Merck hopes to patent subcutaneous version of blockbuster cancer drug Keytruda

US: U.S. drugmaker Merck & Co hopes to patent a new formulation of its $20 billion cancer immunotherapy Keytruda that can be injected under the skin, allowing it to protect its best-selling drug from competition expected as soon as 2028.

For years Merck has relied on Keytruda to fuel its growth. The treatment, approved in 2014, harnesses the body's own immune system to fight cancers with dramatic results. Against advanced lung cancer, it has led to a five-year survival rate in about one-quarter of people compared to 5% of people historically.But the key patents on Keytruda will begin to expire in 2028, opening the door to biosimilars - near copies of expensive biologic drugs whose complex molecules cultivated inside living cells make it impossible to manufacture exact copies.Merck is testing in clinical trials two versions of the drug that can be injected subcutaneously, a quick alternative to infusions, the current delivery method in which patients receive an intravenous drip in a health office once every three or six weeks. The company reported early data from one of those trials last year.While Merck has disclosed that it is developing subcutaneous versions of Keytruda, it has not previously said that it expects the new formulation to become the most widely used version of the drug after it is rolled out and an engine for growth toward the end of the decade.If successful, Merck could begin marketing the new formulation within a few years, a top Merck executive told Reuters. It expects it to fuel Keytruda's growth as it gains approvals in earlier stage cancers. Keytruda now accounts for more than one-third of Merck's sales."We believe that subcutaneous formulation has the potential to be novel, non-obvious and useful, which means we would get a new patent for it," Merck CFO Caroline Litchfield said in an interview, using the terminology for the criteria under U.S. law to determine what technologies merit a patent."The clock for that patent would start ticking from the time we would get that patent approved."While some patients would likely still receive the original formulation if it is being administered along with chemotherapy or other intravenous drugs, the subcutaneous formulation could replace the IV version for most patients, Merck Chief Medical Officer Eliav Barr told Reuters."In theory it could replace everywhere that Keytruda currently is used," Barr said.Drug patents have a guaranteed term of exclusivity for 20 years after receiving a patent under U.S. law, but sometimes the companies are able to add additional patents that extend their exclusivity.For example, the primary patent on Abbvie's arthritis drug Humira expired in 2016 but the drug will not face U.S. competition until 2023, in part because the company eventually received more than 130 patents that protect the drug.Merck's patents on the subcutaneous version of Keytruda could protect that formulation until at least 2040, according to Tahir Amin, co-founder of drug patents watchdog group Initiative for Medicines, Access & Knowledge (I-MAK)."It's the way the pharmaceutical companies now use that system -- it's all about taking up as much space as possible, making it difficult for anybody to enter," Amin said. "Keytruda is going to be the next Humira by all accounts."Asked whether it was motivated more by patent issues than medical need, Merck said it was continuously focused on improving Keytruda and getting it to more patients.Merck said it may seek patents for innovations in how the drug is used, its formulation, the size and schedule of doses and combinations with other drugs."These patent applications, if granted, may provide varying degrees of protection beyond 2028. However, we would continue to point to late 2028 as the most likely timeframe for biosimilar entry into the market," Merck said in a statement.DO PATIENTS PREFER SHOTS?Getting doctors and hospitals to adopt the new formulation before biosimilar competition arrives could help Merck protect more of its Keytruda revenue for longer but is not certain, analysts said. On average, they expect Keytruda revenues to top $30 billion in 2026 and $35 billion by 2028, according to Refinitiv data. "Theoretically, in the US, they could transition all of the market," Mizuho analyst Mara Goldstein said, "depending on how quickly they can get it to market."However, BMO Capital's Evan Seigerman said that private insurers in the U.S. might balk at paying for the more expensive branded product and prefer a biosimilar infusion version. Still, he believes the new formulation could allow the company to hold onto as much as 20 percent of its Keytruda revenue into the 2030s.Two doctors interviewed by Reuters said they were not convinced that the new route of administration represents a significant enough clinical improvement over IV infusions to justify the additional system-wide healthcare costs that might be a product of Merck receiving a new patent."I don't think it's going to improve the safety or the effectiveness of the drug," said Dr. Shailender Bhatia, an oncologist at the Fred Hutchinson Cancer Center in Seattle.Merck's Barr said the easier-to-use formulation of the drug could help patients' health by keeping them on Keytruda and on schedule, and could keep high-risk cancer patients from spending long times in hospital settings where they could be exposed to other diseases."From a quality of life and patient perspective, it's for sure going to be helpful," Barr said.That view is backed by clinical studies that have found that patients prefer subcutaneous injections to intravenous administration which can be time-consuming and invasive.How much hospitals and doctors embrace the method could reflect how they will be impacted by the change financially.Hospitals are typically paid less to administer an injection than a long infusion. That could be offset somewhat if the drug's price is higher, since providers receive a percentage fee for physician-administered drugs, according to Lisa Mulloy, chief pharmacy officer for New York's Northwell Health hospital system.Merck said it would not speculate on the expected price of pipeline products. The infusion's list price is about $185,000 per year, though the drug may cost less with company discounts.Northwell's Mulloy said moving patients to subcutaneous versions of drugs also opens up spots in infusion centers for additional patients.

Propylene Glycol and Hydroxypropyl Guar Nanoemulsion - Safe and Effective in Management of Dry Eye Disease

Dry eye disease (DED) is a chronic condition impacting >30 million people in the United States and >344 million people globally. It is a multifactorial disease of ocular surface characterized by a loss of tear film homeostasis, and accompanied by ocular symptoms such as eye discomfort and visual disturbances.

DED can be classified as aqueous deficient dry eye (ADDE),
evaporative dry eye (EDE), and mixed DED. ADDE is due to tear underproduction
by the lacrimal glands. EDE can occur due to causes related to either lid
(meibomian gland dysfunction [MGD] or blink-related) or ocular surface (mucin
deficiency and contact lens wear), resulting in abnormal lipid secretion, tear
film instability, and excessive evaporation of tears. Although EDE is considered
a leading cause of DED, ADDE can occur without obvious signs of EDE and vice
versa.

Further, iatrogenic DED could be caused by topical or
systemic drugs, contact lens wear, and ophthalmic surgical/non-surgical
procedures. Goblet cells, which produce mucins and contribute to the stability
of the tear film and immune defenses, are extremely sensitive to
toxic/inflammatory stress and are reduced in density after exposure to
iatrogenic factors. Owing to the multifactorial nature of DED, medications that
can target multiple underlying pathologies simultaneously are desirable.

Treatment goal for DED is to restore ocular surface and tear
film homeostasis. Current treatment options in the management of DED include
artificial tears or ocular lubricants, nutraceuticals, anti-inflammatory
agents, tear stimulants, autologous serum, antibiotics, and other therapies
(eg, physical treatments such as warm compresses, complementary medicines such
as herbal products, punctal occlusion, and surgical approaches).

Artificial Tears

Artificial tears, which substitute or supplement the natural
tear film, are the first line option in the management of DED. Artificial tears
improve symptoms (burning, irritation, and/or discomfort), and provide
temporary relief of dryness of the eye, but have not been shown to treat
pathophysiology of DED. Ideal artificial tears should spread uniformly and
evenly, minimize friction during blinks, have minimal visual disturbance upon
instillation, be safe/ convenient to use, and effectively improve the
signs/symptoms of DED.

Artificial tears are formulated with polymeric lubricants,
demulcents, buffering agents (compatible with ocular pH of approximately 7.5),
electrolytes, osmolality adjusting excipients, and surfactants, with/without
preservatives. Most of artificial tears are formulated to supplement either
lipid layer or aqueous layer of the tear film. However, some eye drops are
formulated as emulsions, which contain aqueous lubricants (such as
hydroxypropyl guar [HPG], polyethylene glycol [PEG], and propylene glycol [PG])
and lipid ingredients (such as phospholipid and mineral oil). Lipid-based
artificial tears have been shown to stabilize the tear film lipid layer, reduce
tear evaporation, and improve the signs of MGD and EDE.

One of the major challenges with eye drops is low retention
time. To increase the retention time, viscosity enhancing agents such as
hyaluronic acid (HA) and carboxymethyl cellulose (CMC) are incorporated in eye
drops; these agents also exhibit muco-mimetic properties and reduce desiccation
by forming a protective layer on the ocular surface. However, eye drops with
high viscosity may cause transient visual disturbances (blurred vision) and
also result in debris, leading to intolerance and non-compliance. Thus, to
overcome low ocular retention, in situ gelling chemistry is used; this is
achieved through HPG, a natural polysaccharide, that forms a viscoelastic gel
at ocular pH through cross-linking.

HPG forms the backbone in artificial tears of the SystaneTM
family (Alcon Laboratories, Inc., Fort Worth, TX, USA), which are indicated for
the temporary relief of dry eye symptoms (such as burning and irritation) and
ocular surface protection in patients with DED. Artificial tears of the
SystaneTM family include nonlipid-based (PEG/PG-HPG lubricant eye drop
[SystaneTM Original], PEG/PG-HPG-sorbitol lubricant eye drop [SystaneTM Ultra]
and PEG/PG-HPG/sodium hyaluronate (HA)-sorbitol lubricant eye drop [SystaneTM
Hydration]) as well as lipid-based (PG-HPG microemulsion lubricant eye drop
[SystaneTM Balance] and PG-HPG nanoemulsion lubricant eye drop [SystaneTM
Complete]) formulations.

In this review, Srinivasan and Williams presented the
formulation components, mechanisms of action, and the summary of literature
evidence of PG-HPG nanoemulsion lubricant eye drop (SystaneTM Complete, Alcon
Laboratories, Inc., Fort Worth, TX, USA) that is indicated for temporary relief
of symptoms of burning and irritation in DED.

PG-HPG Nanoemulsion Lubricant Eye Drops

Craig et al demonstrated the treatment of DED according to
disease subtype and severity. In a multicenter, double-masked, parallel group,
randomized controlled trial, 99 participants (mean age, 44±16 years; 64%
female) with DED were enrolled. Participants instilled either lipid-based
PG-HPG nanoemulsion drops (SystaneTM Complete) or nonlipid-based aqueous drops
(SystaneTM Ultra) ≥4 times daily for 6 months; dry eye symptomology, and tear
film and ocular surface characteristics were assessed.49 Both treatments
demonstrated sustained reduction in DED symptoms (Ocular Surface Disease Index
[OSDI], Dry Eye Questionnaire-5 [DEQ-5], and Symptom Assessment Questionnaire
iN Dry Eye [SANDE] scores) from Day 30 onwards (all p≤0.01) and decreased
superior lid wiper epitheliopathy grades from Day 60 onwards (all p≤0.01).

Further, non-invasive tear film breakup time (NITBUT), and sodium fluorescein
and lissamine green staining scores consistently improved from Day 120 onwards
in both groups (all p<0.05).49 Tear film lipid layer grades increased only with PG-HPG nanoemulsion eye drops (from Day 90 onwards); with significantly greater improvement in patients with low lipid layer thickness at baseline (lipid layer grade ≤3; p=0.01).49 Hence, both lipid-based and non-lipid-based artificial tears provided symptom relief within a month.49 Improvements in the tear film stability and ocular surface characteristics were slower than the symptomatic improvements.49 Further, both formulations showed long-term efficacy and a good tolerability profile across DED subtypes; however, improvement in tear film lipid layer grade was observed only with PG-HPG nanoemulsion drops; particularly in subgroup of patients with evaporative DED due to tear lipid insufficiency (with baseline lipid layer grade ><0.05).

Tear film lipid layer grades increased only with PG-HPG
nanoemulsion eye drops (from Day 90 onwards); with significantly greater
improvement in patients with low lipid layer thickness at baseline (lipid layer
grade ≤3; p=0.01). Hence, both lipid-based and non-lipid-based artificial tears
provided symptom relief within a month. Improvements in the tear film stability
and ocular surface characteristics were slower than the symptomatic
improvements. Further, both formulations showed long-term efficacy and a good
tolerability profile across DED subtypes; however, improvement in tear film
lipid layer grade was observed only with PG-HPG nanoemulsion drops; particularly
in subgroup of patients with evaporative DED due to tear lipid insufficiency
(with baseline lipid layer grade ≤3).

In a Phase IV, openlabel, single-arm,
multicenter trial, patients with DED (N=134; 56.6±14.8 years; 75.4% female)
instilled one drop of PGHPG nanoemulsion in each eye, twice daily for 28 days.
The instillation of PG-HPG nanoemulsion eye drops increased tear film break-up
time (TFBUT) by 1.5±2.8 seconds at 14 days; and the improvement remained consistent
through 28 days. It also improved (decreased) ocular discomfort at 14 days
(mean±SD change in visual analog scale [VAS] score, −17.3±24.80). Moreover,
subgroup analysis of patients with ADDE, EDE, and mixed DED indicated that
PG-HPG nanoemulsion was effective and well tolerated in all three types of DED.
PG-HPG nanoemulsion improved tear film stability, and signs and symptoms of DED

DED is a multifactorial condition with ADDE, EDE, and mixed
etiologies. Artificial tears are the backbone in the management of DED.
Lipid-based lubricant eye drops with viscoelastic characteristics are
beneficial in providing temporary relief of dry eye symptoms.

PG-HPG and borate components in PG-HPG nanoemulsion
lubricant eye drops form a thin viscoelastic layer that prolongs retention of
demulcent; thus, provides long-term surface hydration and moisture retention,
and ocular surface protection by improving cell barrier functions and cell
recovery, and temporary relief of symptoms in DED. Moreover, it provides tear
film stability between and during blinks owing to viscoelastic properties of
HPG. Further, PG-HPG nanoemulsion formulation helps to optimize ocular surface
coverage of lipids that is beneficial in replenishing the tear film lipid
layer. Additionally, PG-HPG nanoemulsion lubricant eye drops in the form of
multidose preservative-free system (with Novelia® bottles) is effective,
convenient, and well tolerated in DED patients who have intolerance to
preservatives with long-term eye drop use.

Clinically, PG-HPG nanoemulsion lubricant eye drops have
been shown to improve dry eye symptoms, enhance tear film stability, and lipid
layer thickness; hence, they help to restore eye surface health and provide
symptom relief in patients with DED, regardless of subtypes. Moreover, PG-HPG
nanoemulsion relieves ocular dryness and discomfort associated with daily
contact lens wear, and in prophylactic treatment of dry eye against adverse
environmental conditions.

Conversely, other lipid-based and/or liposome-based
lubricant eye drops, shown to mimic tear film composition, provide ocular surface
benefits and improve signs of dry eye; however, large-scale controlled clinical
studies are required to obtain more robust evidence on the efficacy. With over
a demi-decade of usage, PG-HPG nanoemulsion lubricant eye drops are effective,
convenient to use, and well tolerated in DED, regardless of its subtypes.

Heart transplantation's newest breakthrough: donation after circulatory death

Heart transplantation is limited by organ availability. Transplant programs involve marginal donors with risk characteristics include older age, size mismatch, left ventricular hypertrophy, poor ejection fraction, and extended donor ischemia durations. Brain death or circulatory death is required for deceased organ donation . All brain functions stop after brain death.

Cold solution flushing stops organ function during DBD donor organ assessment and procurement. Circulatory death donors have irreparable damage and cannot be saved. After treatment is discontinued, the donor dies of circulatory failure (no blood pressure, pulse, or heartbeat). Before organ harvesting, circulatory death is certified after a 5-minute standoff.

Ischemic damage threatens all donor organs. Ischemic damage destroys pump and electrical performance in DCD hearts. Recent breakthroughs in machine perfusion (MP) have permitted resuscitation of DCD hearts and successful transplant. DCD hearts may boost donor numbers by 50%.

DCD Heart Recovery

Direct procurement and ex situ perfusion (DPP) and normothermic regional in situ perfusion (NRP) are DCD heart procurement methods.

DPP uses ex situ MP. After circulatory death is confirmed, the heart is flushed with cold crystalloid cardioplegia, obtained, back table instrumentation, and reperfused with normothermic blood. Only TransMedics Organ Care System (OCSTM) (Andover, MA, USA) is FDA-approved for ex situ perfusion of DCD hearts. OCS machine priming before cardiac recovery takes 1100 mL donor blood. Cannulated aorta and pulmonary arteries and LV vent avoid distension. The OCS system keeps the heart normothermic and beating throughout resuscitation and transfer . Lactate metabolism, physical examination, and coronary flow predict heart function and organ viability. Before implant, cardioplegia freezes the heart.

NRP uses open cardiopulmonary bypass (CPB). Death declaration and standoff follow DCD protocol. The donor right atrium and ascending aorta are cannulated for CPB. Before CPB thoraco-abdominal organ reperfusion, the aortic arch arteries are constricted to isolate brain circulation. Venting the innominate artery prevents brain circulation. Heart function recovers after 45–60 minutes. Weaning CPB allows cardiac function testing. After cardioplegia, the heart is carried in cold static storage, normothermic, or hypothermic MP storage.

DCD Heart Transplantation Evolution

DCD hearts are not new. Dr. Christiaan Barnard used NRP to accomplish the first DCD donor heart transplant in 1967. DCD was abandoned due to brain death criteria and ischemia heart damage concerns. Denver Children's Hospital transplanted three pediatric DCD hearts in 2004. Ten years later, Sydney's St. Vincent's Hospital launched a DCD program using DPP In 2015, Papworth Hospital in Cambridge, UK completed NRP DCD heart transplants.

In 2019, the first adult DCD heart transplant was conducted in the US as part of a randomized controlled experiment comparing OCS to DBD cold storage. NYU conducted the first adult DCD NRP heart transplant in 2020. DCD heart transplants boost donor organ yield. Thoraco-abdominal NRP improves DCD liver and kidney transplant survival.

Results -

International studies reveal a 30-48% donor pool increase with DBD heart transplant results. Messer and colleagues analyzed DCD and DBD cardiac transplants. DCD 92% and DBD 96% had similar 90-day and 1-year survival. There was no significant difference in primary graft malfunction requiring extracorporeal membrane oxygenation (ECMO) (DCD 15% vs. DBD 6%, p = 0.12) or intra-aortic balloon pump (IABP) (DCD 32% vs. DBD 23%, p=0.28). There was also no significant difference in intensive care unit (ICU) or hospital durations of stay. 57 DCD transplant hearts were DPP and 22 NRP with OCS perfusion. Survival was comparable, but NRP transplants needed fewer ventilator days, dialysis, and hospital stays. US DCD heart multicenter trials randomized 180 patients to 90 OCS and 90 DBD hearts. Six- and 12-month post-transplant survival were similar. DCD hearts used 89%.

Ethics -

DCD heart transplant raises ethical issues. Circulatory death is irreversible cardiopulmonary failure. The phrase "irreversible" raises worries of breaking the deceased donor rule by restoring circulation to the thoraco-abdominal organs using NRP. Before intervention, the donor fulfilled requirements and was proclaimed dead. The obligatory standoff time indicates no autoresuscitation. NRP does not revive the patient or restore pre-withdrawal non-life-sustaining damage.

Before bypass, the head vessels are blocked and ventilated to address concerns about NRP resuming neurologic function.

It is vital to highlight that if the duration from removal of life support to death exceeds the permissible f-WIT for solid organ donation, donors stay on hospice and the process to death continues. In this situation, the donor may still be able to give additional tissue for transplant or study.

Summary of findings

Widespread use of DCD heart transplant has been hindered by ischemia damage. However, success of employing DPP and NRP procedures has led in exponential increase of DCD heart transplant in recent years. MP also allows the study of innovative therapies like gene therapy and mitochondrial transplant, which might repair and reimplant failing hearts.

Many advantages of DCD heart transplant encourage its broader spread adoption: enlarging the donor pool, shortening waiting periods, enhancing organ quality, boosting total organ yield per donor are among them.

Herbicide causes poisoning at the Montecristi school

Herbicide would have been the cause of nine teachers being intoxicated with poisoning symptoms at the basic level school “Aurora Tavares Ballard” in the municipality of San Lorenzo de Guayubn, in the province of Montecristi, yesterday.

As a result, the National Police launched an extensive investigation into the poisoning suffered by the educators, prompting the educational district 13-02 to suspend classes until next Monday to disinfect the facility and environment, according to the center’s director. Isabel Veras is an educator.

The Ministry of Public Health was able to determine that the cause of the poisoning was herbicide, which occurred after the teachers inhaled a highly toxic substance sprayed on the campus. “We were able to contact a person who lives in front of the school, and he showed us the container in which the herbicide was supplied, which is a burner for cleaning a patio,” a source close to the investigation said.

A woman who lives near the school would have sprayed this liquid to kill the herbs in her yard, but according to the epidemiologist in charge of the Montecristi health province, she sprayed more than the recommended amount, and with the arrival of the wind, the substance entered the school and caused the poisoning. So far, 15 people, including teachers and children, have been taken to the hospital with poisoning symptoms.

The National Police are expected to look into the situation further so that the person responsible can be brought to justice if necessary.

The sociopolitical crisis hinders the fight against AIDS in Haiti

The fight against HIV/AIDS in Haiti is being hampered by an acute sociopolitical crisis, which threatens to undermine the significant advances made in the last decade.

The rise in cases is primarily due to two factors, lamented this community health specialist on World AIDS Day this Thursday: The lack of fuel paralyzed Haiti, preventing patients from attending medical appointments, and insecurity prevented people living in the so-called “red zones” from visiting health centers to receive care.

According to the most recent Ministry of Public Health and Population data, there are approximately 150,000 people in Haiti living with HIV/AIDS, 145,000 of who are adults and 5,700 of whom are children. 85% of those infected with the virus are aware of their situation, and 90% are receiving treatment. In 2021, 4,300 people became infected with HIV and 1,500 died from AIDS-related illnesses, bringing the total number of deaths in the country to 217,000 since the outbreak began.

Women account for 59% of those living with HIV, making them the most vulnerable to the disease due to factors such as higher poverty, more visits to health centers than men, greater vulnerability, and a lack of economic and financial autonomy. According to health officials, approximately 133,000 people have active access to antiretrovirals, to eradicate the disease in Haiti by 2030.

FIR for Attacks on Doctors, Medical Professionals need to be Registered within one hour: Kerala HC directs Police

Ernakulam: Taking cognizance of the increasing instances of attacks on doctors, the Kerala High Court has recently directed the police authorities to ensure that a First Information Report (FIR) needs to be registered on every incident of attack on a doctor or medical professionals within one hour.

The HC bench comprising Justice Devan Ramachandran and Justice Kauser Edappagath issued this direction as a primary step to address the issue of violence against doctors.

Suo Motu impleading the State Police Chief, the bench observed, "as a first step, in addition to the earlier directions, we are of the firm view that every incident of attack on a Doctor or a Healthcare Professional, including any other staff of the Hospital - be that Security or other - will have to be taken cognizance of by the Station House Officer of the concerned Police Station not later than one hour from the time on which it is reported to him."

"This can be under the Special Law applicable, or under the Indian Penal Code; but an FIR will be need to be registered within the afore time frame, which alone will ensure that the perpetrator/s understands that action is swift and quick," further noted the bench.

Earlier this year, the Kerala High Court had suggested the Government to consider deploying police presence in hospitals, especially in the most sensitive areas and later extend it to other hospitals as well.

Such observations had come from the High Court bench while it was considering a case related to the an attack on a nurse and a doctor at Neendakara Taluk Hospital.

Medical Dialogues had earlier reported that while considering the matter, the High Court had referred to the reports of 'routine' attacks on Healthcare personnel and observed that even though Kerala Healthcare Service Act 2012 has provision for strict penalties for assault against healthcare workers, the legal provision was not sufficient to stop the assaults.

Therefore, the HC Division bench comprising of Justice Devan Ramachandran and Justice Kauser Edappagath had noted back in June 2022, "No doubt, the Kerala Healthcare Service Persons and Healthcare Service Institutions (Prevention of Violence and Damage to Property) Act, 2012 provide for very stringent provisions and punishment. However, as the present case demonstrates, it is not always the best deterrent. We, therefore, have to think about placing hospitals, particularly in remote areas, under police protectional cover, more in the evenings and nights, so that the doctors and nurses can work without apprehension."

While the bench was considering these matters after almost six months, Sri.S.Gopakumaran Nair, learned Senior Counsel, instructed by Sri.S.Prashanth; and Sri.K.Anand informed the bench that for about 12 month period from June, 2021, the number of attacks recorded was in excess of 138.

Taking note of this, the bench observed, "This is certainly distressing, because, statistically, this means that there are at least 10 or 12 attacks every month."

Clarifying that the court is more concerned because despite the court orders in the past, the attacks have only increased in number. The court noted, "We are more concerned because we had been issuing orders in the past, under the hortative hope that the official system would function faultlessly; and that the citizens would also be aware of the imperative requirement to treat the Healthcare System with the respect it deserves."

"The discussions at the Bar today clearly show that, unless a sense of fear of law is instilled into the citizens, nothing can really change. Experience has shown us that citizens are not fearful of law, but of apprehension in case of misconduct or infraction," it further observed.

The bench added that prima facie it is perhaps because citizens get the impression that the processes of law are slow and that they would not be taken to task, that such recurrent occurrences happen.

"The fact that the Government Hospital System is overwhelmed and that the number of patients are escalating by the day, are common knowledge. Unless the Doctors and Healthcare Professionals are able to act in peace and calm, it would become impossible for the system itself to sustain," the bench observed at this outset.

Noting that all the stakeholders should inform the court about the steps that have been taken in this regard, the bench added, "Obviously, therefore, we require all the stakeholders, including the Government, to inform us what steps had been and have to be taken to ensure this."

Meanwhile, the Senior Government Pleader Sri S. Kannan informed the bench that every step as ordered by the HC bench earlier, including the establishment of Police Outposts in hospitals, had been implicitly adhered to by the Government. The Government counsel further submitted that the State was willing to accept any other suggestions- either by the Court or by the stakeholders in this regard.

"We also assured that the Government shares the concern of this Court qua the integrity of the Healthcare System," noted the court at this outset.

Therefore, as a first step the Court has directed the police to ensure that FIRs are lodged against the instances of attacks on doctors and healthcare professionals within one hour.

"As said above, this is only the first step and we will certainly add to this in the days to come, depending upon the inputs which are to be received from the parties in these cases," noted the court.

Suo motu impleading the State Police Chief, the bench remarked,

"We do so because, the said Authority will be the best Officer to ensure that our directions as below are effectively implemented, through necessary Circulars or such other instructions."

"In the afore perspective, we hereby order that every Station House Officer concerned, to whom, or to whose Station, a complaint of atrocity or attack or harm on any Healthcare Professional – be that Doctors, Nurses, staffs, security or such other, or against the property of a Hospital- shall be recorded as a first information and a case registered within a period of one hour from the time on which such information is obtained or gathered," read the order.

"Needless to say, swift action thereafter shall be initiated, including to apprehend the Offenders, as and when it requires so, leading to prosecution and such other, as the law warrants," it further added.

Further, requesting the State to ensure that the citizens are aware of the gravity of the offence of an attack on medical professionals, the bench added in the judgement,

"...we request them to ensure that the citizens are told, by appropriate methods, the gravity of the offence of an attack on a Hospital or a Healthcare Personnel; and the manner in which this Court proposes to deal with it in future."

The Business of Clinical Trials Is Booming. Private Equity Has Taken Notice.

After finding success investing in the more obviously lucrative corners of American medicine — like surgery centers and dermatology practices — private equity firms have moved aggressively into the industry’s more hidden niches: They are pouring billions into the business of clinical drug trials.

To bring a new drug to market, the FDA requires pharmaceutical firms to perform extensive studies to demonstrate safety and efficacy, which are often expensive and time-consuming to conduct to the agency’s specifications. Getting a drug to market a few months sooner and for less expense than usual can translate into millions in profit for the manufacturer.

That is why a private equity-backed startup like Headlands Research saw an opportunity in creating a network of clinical sites and wringing greater efficiency out of businesses, to perform this critical scientific work faster. And why Moderna, Pfizer, Biogen, and other drug industry bigwigs have been willing to hire it — even though it’s a relatively new player in the field, formed in 2018 by investment giant KKR.

In July 2020, Headlands announced it won coveted contracts to run clinical trials of covid-19 vaccines, which would include shots for AstraZeneca, Johnson & Johnson, Moderna, and Pfizer.

In marketing its services, Headlands described its mission to “profoundly impact” clinical trials — including boosting participation among racial and ethnic minorities who have long been underrepresented in such research.

“We are excited,” CEO Mark Blumling said in a statement, to bring “COVID-19 studies to the ethnically diverse populations represented at our sites.” Blumling, a drug industry veteran with venture capital and private equity experience, told KHN that KKR backed him to start the company, which has grown by buying established trial sites and opening new ones.

Finding and enrolling patients is often the limiting and most costly part of trials, said Dr. Marcella Alsan, a public policy professor at Harvard Kennedy School and an expert on diverse representation in clinical trials, which have a median cost of $19 million for new drugs, according to Johns Hopkins University researchers.

Before covid hit, Headlands acquired research centers in McAllen, Texas; Houston; metro Atlanta; and Lake Charles, Louisiana, saying those locations would help it boost recruitment of diverse patients — an urgent priority during the pandemic in studying vaccines to ward off a disease disproportionately killing Black, Hispanic, and Native Americans.

Headlands’ sites also ran, among other things, clinical studies on treatments to combat Type 2 diabetes, postpartum depression, asthma, liver disease, migraines, and endometriosis, according to a review of website archives and the federal website ClinicalTrials.gov. But within two years, some of Headlands’ alluring promises would fall flat.

In September, Headlands shuttered locations in Houston — one of the nation’s largest metro areas and home to major medical centers and research universities — and Lake Charles, a move Blumling attributed to problems finding “experienced, highly qualified staff” to carry out the complex and highly specialized work of clinical research. The McAllen site is not taking on new research as Headlands shifts operations to another South Texas location it launched with Pfizer.

What impact did those sites have? Blumling declined to provide specifics on whether enrollment targets for covid vaccine trials, including by race and ethnicity, were met for those locations, citing confidentiality. He noted that for any given trial, data is aggregated across all sites and the drug company sponsoring it is the only entity that has seen the data for each site once the trial is completed.

A fragmented clinical trials industry has made it a prime target for private equity, which often consolidates markets by merging companies. But Headlands’ trajectory shows the potential risks of trying to combine independent sites and squeeze efficiency out of studies that will affect the health of millions.

Yashaswini Singh, a health economist at Johns Hopkins who has studied private equity acquisitions of physician practices, said consolidation has potential downsides. Singh and her colleagues published research in September analyzing acquisitions in dermatology, gastroenterology, and ophthalmology that found physician practices — a business with parallels to clinical trial companies — charged higher prices after acquisition.

“We’ve seen reduced market competition in a variety of settings to be associated with increases in prices, reduction in access and choice for patients, and so on,” Singh said. “So it’s a delicate balance.”

Dr. Aaron Kesselheim, a professor of medicine at Harvard Medical School, called private equity involvement in trials “concerning.”

“We need to make sure that patients” know enough to provide “adequate, informed consent,” he said, and ensure “protections about the privacy of the data.”

“We don’t want those kinds of things to be lost in the shuffle in the goals of making money,” he said.

Blumling said trial sites Headlands acquired are not charging higher prices than before. He said privacy “is one of our highest concerns. Headlands holds itself to the highest standard.”

Good or bad, clinical trials have become a big, profitable business in the private equity sphere, data shows.

Eleven of the 25 private equity firms identified by industry tracker PitchBook as the top investors in health care have bought stakes in clinical research companies, a KHN analysis found. Those companies have been involved in studies ranging from covid vaccines to treatments for ovarian cancer, Parkinson’s disease, and Alzheimer’s.

Contracted firms also analyze patient data and prepare materials to secure approval from regulatory agencies, in hopes of getting more drugs to market faster. And a big draw for investors: Clinical research companies make money whether or not a drug succeeds, making it less risky than investing in a drug company.

The number of clinical trials has exploded to more than 434,000 registered studies this year as of late November, more than triple the number a decade ago.

Still, most trial sites are physician practices that don’t consistently perform studies, according to a presentation by Boston-based investment firm Provident Healthcare Partners.

“Independent sites are being purchased by private equity, and they’re moving into larger site groups of 30, 40, and then their game plan is to roll that up into a business and then sell it again,” said Linda Moore Schipani, CEO of Clinical Research Associates, a Nashville-based company that worked on covid vaccine trials for AstraZeneca, Novavax, and Pfizer. “That’s kind of the endgame.”

Headlands is a prime example. It announced in November 2019 that it would acquire six centers in the U.S. and Canada, including three sites in Texas and Louisiana owned by Centex Studies that would help improve participation among Hispanics and African Americans.

It has made other acquisitions since then and opened new sites in areas with “extremely limited trial options,” something Blumling says distinguishes his company.

“I’m not an evangelist for private equity,” Blumling said. “The ability of KKR to be willing to invest in something that is a three- to five-year return versus a one- to two-year return is something that you won’t see out there.”

A research center in Brownsville, Texas — a stone’s throw from the U.S.-Mexico border and where 95% of the population is Hispanic or Latino — is one of several where it is partnering with Pfizer to boost patient diversity.

To recruit patients, Headlands “is really going beyond what a lot of sites do, which is social media,” Blumling said in an interview. “It’s going within churches, community fairs, really getting out into as much as possible the broader community.”

Headlands closed the Houston and Lake Charles sites because of staffing issues, Blumling said, and finished or moved their studies elsewhere. Blumling said the decision to close those locations “did not have anything to do with the speed of trials.”

Similarly, he said, Headlands is moving the McAllen site’s operations to Brownsville “because it had a larger population of trained personnel.”

“We want to continue to grow sites and do great work,” Blumling said. “If we can’t find the people in order to do that at the quality that we demand, which is at the highest level, then it doesn’t make sense to keep those sites.”

‘The Writing to Me Was on the Wall’

In 2006, Devora Torrence co-founded Centex Studies, which she described as “my little mom and pop business” in a 2021 podcast about female entrepreneurs in science. She said a flurry of interest from private equity came at the end of 2018. The appeal was evident: Drug companies were relying on bigger clinical trial networks.

“The thing is speed, getting it to market. With a bigger network, you get that speed,” Torrence said on the podcast. “The writing to me was on the wall that either I get some outside investment and scale up myself, or kind of listen to these guys and see if maybe now would be the right time to exit.”

Joining Headlands had its benefits during the pandemic because she could “lean on” its other sites with experience running vaccine trials. “Had we not gotten those … we may not still be here,” Torrence said.

Torrence, whose LinkedIn profile said she left the company in 2021, didn’t respond to messages from KHN.

Lyndon Fullen, a health care consultant and former Centex employee, said private equity provides funding that allows companies to add study sites.

“I completely support it,” he said. “If it’s about reaching that large patient population, it’s of course better to have larger groups with that funding.”

Opportunity in Long Covid

Contract research organization Parexel saw opportunity in the covid pandemic — millions of people were developing long covid after infection and there were few, if any, meaningful treatment options.

The company, which employs more than 19,000 people, was acquired in 2021 by EQT Private Equity and Goldman Sachs’ private equity arm for $8.5 billion, billions more than the $4.5 billion that private equity firm Pamplona Capital Management paid when it took Parexel private in 2017.

A growing body of research shows the debilitating effects of long covid, including a recent study of tens of thousands of patients in Scotland where nearly half had not fully recovered months later. But treatments addressing its root causes could be years away. “It’s a huge number of people,” said Dr. Nathalie Sohier, who leads Parexel’s infectious diseases and vaccines franchise. “There’s a lot of need.”

Long covid represents the promise and peril of the work to develop new drugs: Millions of patients create a potentially lucrative market for drug companies, and yet researchers and industry experts say they are reluctant to jump in. In part, that’s because “it’s not a well-defined disease, and that really makes it highly risky for companies to invest in research,” said Cecil Nick, a vice president for Parexel.

“How are we going to be able to tell the FDA that our drug works? We can’t count the number of people who died; we can’t count the number of people in the hospital,” said Dr. Steven Deeks, a University of California-San Francisco professor who is running an observational study on long covid patients.

As of August, among more than 4,400 covid studies, only 304 focused on long covid. A third of those were related to drug development, Sohier said.

Sohier said “there are few” companies in its long covid program. That hasn’t stopped Parexel from pitching itself as the ideal partner to shepherd new products, including by doing regulatory work and using remote technology to retain patients in trials. Parexel has worked on nearly 300 covid-related studies in more than 50 countries, spokesperson Danaka Williams said.

Michael Fenne, research and campaign coordinator with the Private Equity Stakeholder Project, which studies private equity investments, said Parexel and other contract research organizations are beefing up their data capacity. The aim? To have better information on patients.

“It kind of ties into access and control of patients,” Fenne said. “Technology makes accessing patients, and then also having more reliable information on them, easier.”

Roche to stop all Gantenerumab studies in early Alzheimer's disease

Chicago: Swiss drugmaker Roche is closing down most clinical trials of its experimental Alzheimer's drug gantenerumab after it failed to slow advance of the mind-robbing disease in a pair of large, late-stage studies, the company said on Wednesday.

Roche presented full results of twin trials at an Alzheimer's meeting in San Francisco after announcing in November that the drug had failed in the two trials.

Unlike Eisai Co Ltd and Biogen Inc's lecanemab, which appears to be on track for U.S. regulatory approval after presenting successful trial results on Tuesday, Roche's drug did not show a statistically significant benefit in patients with mild cognitive impairment and early Alzheimer's disease.

Both drugs are designed to remove forms of the protein beta amyloid from the brain, sticky plaques believed to play a major role in the disease.

While Eisai's infusion succeeded in slowing the advance of Alzheimer's by 27% after 18 months, Roche's drug reduced decline by just 8% in the Graduate I study and 6% in the Graduate II study compared with a placebo after two years.

A key difference may have been in the drug's ability to clear amyloid from the brain.

In a presentation on Wednesday, researchers said gantenerumab, which is given by injection, only achieved amyloid clearance in 28% of patients in the Graduate I trial and 25% in Graduate II after two years, half of what the company expected to see.

Lecanemab, by contrast, cleared amyloid in 68% of those in the study after 18 months.

Dr. Howard Fillit, chief science officer at the Alzheimer's Drug Discovery Foundation, said there are a number of reasons why Roche's drug may have failed, including differences in chemistry, dosing, and the way it was administered via injection versus infusion.

But the fact that the drug failed to remove amyloid deposits in the brain as expected clearly played a role, he added.

The field of Alzheimer's research is littered with failure and disappointment, including for several drugs in the same class, and previous efforts to prove gantenerumab's worth.

In 2014, the drug failed to show a benefit when given at a lower dose among patients with mild Alzheimer's, and it failed again in 2020 in a Washington University School of Medicine trial of patients with an inherited form of Alzheimer's.

"Obviously, within the class, some drugs are working and some aren't," Fillet said.

A Roche spokesman said in an emailed statement that the company will stop all gantenerumab studies in early Alzheimer's disease, including extension studies of the Graduate trials and the Skyline Phase III study in patients with evidence of amyloid in the brain but no signs of cognitive decline.

"In the Graduate studies, the level of amyloid removal was lower than expected. We expect the same, lower effect in the Skyline population, and consider this insufficient to continue," the spokesman said.

Roche is still testing a different formulation of gantenerumab called trontinemab, designed to ferry the drug across the blood-brain barrier - protective blood vessels that prevent chemicals in the bloodstream from entering the brain - in hopes of getting more of the treatment into the brain.

"We remain committed to Alzheimer's disease and will direct our focus to new and potentially improved approaches for new treatments," Rachelle Doody, Roche's global head of neurodegeneration drug development, said in a statement.

Biomarker in urine -the first to reveal early-stage Alzheimer's disease?

Alzheimer's disease can remain undetected
until it is too late to treat. Large-scale screening programs could help to
detect early-stage disease, but current diagnostic methods are too cumbersome
and expensive. Could a simple urine test reveal if someone has early-stage
Alzheimer's disease and could this pave the way for large-scale screening

Alzheimer's disease can remain undetected
until it is too late to treat. Large-scale screening programs could help to
detect early-stage disease, but current diagnostic methods are too cumbersome
and expensive. Could a simple urine test reveal if someone has early-stage
Alzheimer's disease and could this pave the way for large-scale screening
programs?

A new study published to Frontiers is the
first to identify formic acid as a sensitive urinary biomarker that can reveal
early-stage Alzheimer's disease, potentially paving the way for inexpensive and
convenient disease screening.

The
researchers tested a large group of patients with Alzheimer's disease of
different levels of severity and healthy controls with normal cognition to
identify differences in urinary biomarkers.

They found that urinary formic acid is a
sensitive marker of subjective cognitive decline that may indicate the very
early stages of Alzheimer's disease. Current methods to diagnose Alzheimer's
are expensive, inconvenient, and unsuitable for routine screening. This means
that most patients only receive a diagnosis when it is too late for effective
treatment. However, a non-invasive, inexpensive, and convenient urine test for
formic acid could be just what the doctor ordered for early screening.

Alzheimer's disease is a continuous and
concealed chronic disease, meaning that it can develop and last for many years
before obvious cognitive impairment emerges. The early stages of the disease
occur before the irreversible dementia stage, and this is the golden window for
intervention and treatment. Therefore, large-scale screening for early-stage
Alzheimer's disease is necessary for the elderly.

Urinary formic acid showed an excellent
sensitivity for early Alzheimer's screening. "The detection of urine biomarkers
of Alzheimer's is convenient and cost-effective, and it should be performed
during routine physical examinations of the elderly.

Game-changer machine to eradicate mosquitoes, treat burns coming 2023

LEADERS in the science and technology sector are confident that the multi-purpose gamma irradiation technology, which is expected to arrive in the island next year, will be a game changer.

"The equipment is purchased. What really happened to us was COVID-19 and the whole world slowed down as we all know, for two years. But I am hoping for the latter part of next year, it will be well on its way," said Charles Grant, director general at International Centre for Environmental and Nuclear Sciences (ICENS).

Grant was among several officials in the science and technology sector who guided journalists and tertiary students on an open day and media tour of ICENS at The University of the West Indies, Mona on Tuesday.

Research scientist at ICENS Johann Antoine told the Jamaica Observer that gamma irradiation technology — a tool used for sterilisation, radiotherapy, and nuclear energy — will help in reducing diseases, and improve the agricultural and medical industry in Jamaica.

"We are going to use that for the sterile insect technique to raise male insects that are pests and then to sterilise in an effort to lower the population of these pests. So, let's say its mosquitoes, which is our first focus, you are lowering the population of mosquitoes so there will be less dengue, Zika virus and chikungunya," he said.

"We are just waiting on the delivery of the actual instrument and as soon as we do that, we connect with the Ministry of Health and Wellness who have an insectary. They are going to supply the male mosquitoes and we will irradiate," he added.

Antoine said that the multi-purpose tool will also be used to sterilise skin grafts for burn victims and crop mutation.

"The irradiator will create beneficial traits in crops such as drought resistance and disease resistance. So there is a direct relationship with agriculture and we are doing that in connection with the Scientific Research Council [SRC] so that we can offer better crops —crops that will have to face that climate change adaptation that we will have to face so that Jamaica can remain food secure," he added, noting that nuclear technology and power generation are also being explored.

Chairman at SRC Dr Parris Lyew-Ayee Jr, who said he is looking forward to the different services the gamma irradiation technology will offer, said, "All of those things are going to have some sort Ne atom impact on Jamaica in terms of being able to enable existing technologies, and sectors to become more productive."

"It is all well and good for us to be able to keep on swatting flies, or turning over standing water objects to prevent the spread of mosquitoes but there are technologies that train people to do more than that."
