Biotech this week, Nov. 8

Biotech stocks reversed course and closed the week ended Nov. 5 lower, squandering the gains notched early in the week.

What was good news for Pfizer, Inc. 

 (Get Free Alerts for PFE) turned out to be negative for several others engaged in COVID-19 vaccine and treatment research. Pfizer announced Friday its oral COVID-19 pill Paxlovid reduced the risk of COVID-19-related hospitalization or death by 89%.

Merck & Co., Inc. (MRK: NYSE), which also has a competing medication in the pipeline, shed close to 10% on Friday.

Stocks also reacted to the earnings, which came in thick and fast during the week. Five stocks belonging to the biotech and diagnostics spaces, debuted on Wall Street during the week.

Here are the key upcoming catalysts that biotech investors are on in the unfolding week:

Abstract

Difficulty in controlling SARS-CoV-2 transmission made the ability to inactivate viruses in aerosols and fomites to be an important and attractive risk reduction measure. Evidence that light frequencies have the ability to inhibit microorganisms has already been reported by many studies which, however, focused on ultraviolet (UV) wavelengths, which are known to induce potential injury in humans. In the present study, the effect on suspensions of SARS-CoV-2 of a Light Emitting Diode (LED) device capable of radiating frequencies in the non-hazardous visible light spectrum (VIS) was investigated. In order to evaluate the efficiency of viral inactivation, plaque assay and western blot of viral proteins were performed. The observed results showed a significant reduction in infectious particles that had been exposed to the LED irradiation of visible light. Furthermore, the analysis of the intracellular expression of viral proteins confirmed the inactivating effect of this irradiation technology. This in vitro study revealed for the first time the inactivation of SARS-CoV-2 through LED irradiation with multiple wavelengths of the visible spectrum. However additional and more in-depth studies can aim to demonstrate the data obtained during these experiments in different matrices, in mutable environmental conditions and on other respiratory viruses such as the influenza virus. The type of LED technology can decisively contribute on reducing virus transmission through the continuous sanitation of common environments without risks for humans and animals.

Exploring the Mystery of COVID-19 Vaccine-Linked Heart Inflammation

 In exceptionally rare cases, people, typically young males, negatively respond to the mRNA COVID-19 vaccines manufactured by Pfizer-BioNTech and Moderna. These responses include myocarditis, the inflammation of the heart muscle, and pericarditis, which is the inflammation of the sac surrounding the heart muscle. The risk of myocarditis and pericarditis from mRNA vaccines appears mild and temporary, and lower than the risk of the same conditions from COVID-19.

Nonetheless, researchers aren’t sure why the mRNA vaccines appear to, in rare cases, cause this condition. According to the U.S. Food and Drug Administration (FDA), the risk seems higher within seven days of the second jab of the vaccines. In vaccinated individuals, it is typically mild and requires minimal treatment.

The U.S. Centers for Disease Control and Prevention (CDC) indicates that the benefits of preventing COVID-19, hospitalizations, and death from the vaccines outweigh the risks of myocarditis and pericarditis.

A study published in 1996 notes that, in North America, myocarditis is caused by viral infections “with a wide spectrum of natural history. The majority of patients recover spontaneously, but those with persistent ventricular dysfunction face a 20% one-year mortality. Myocarditis initiates as viral disease, and molecular techniques have confirmed viral persistence.”

The Mayo Clinic adds that myocarditis can result from a drug reaction or part of more general inflammatory conditions. Symptoms of myocarditis include chest pain, fatigue, shortness of breath, and rapid or irregular heartbeats.

In a study conducted by Kaiser Permanente Southern California (KPSC) and published in JAMA Internal Medicine on October 4, 2021, in a cohort of 2,392,924 members of KPSC who had received at least one dose of COVID-19 mRNA vaccines, there were 15 cases of confirmed myocarditis, two after the first dose and 13 after the second. This is an observed incidence of 0.8 cases per 1 million first doses and 5.8 cases per 1 million second doses over a 10-day observation window. All were males with a median age of 25 years.

A CDC study cites rates of about 12.6 cases per million doses of second-dose mRNA vaccine in people 12 to 39 years of age. The patients typically reported chest pain two to three days after a second dose and had elevated cardiac troponin levels. ECG was abnormal.

The authors of the study say this warrants further investigation and note that “no relationship between COVID-19 mRNA vaccination and postvaccination myocarditis can be established given the observational nature of this study.”

According to a CDC study, from March 2020 to January 2021, the risk of myocarditis was 0.146% in patients diagnosed with COVID-19 during an inpatient or hospital-based outpatient encounter and 0.009% in patients not diagnosed with COVID-19. Another way of putting it is that the risk of myocarditis was 15.7 times higher for people with COVID-19 than healthy people.

Some theories as to why the mRNA vaccines might cause myocarditis revolve around the spike protein. In the SARS-CoV-2 virus, which causes COVID-19, the spike protein helps the virus enter human cells then take over the cell’s genetic machinery to reproduce itself. The mRNA vaccines code for segments of the spike protein, which then trains the immune system to recognize the spike protein and thus recognize the virus.

Another theory, according to Biykem Bozkurt, M.D., Ph.D., a professor of medicine specializing in cardiology at Baylor College of Medicine in Houston, says there might be similarities between the spike protein and proteins in the heart muscle. This is dubbed the “molecular mimicry” theory, but it hasn’t been fully tested in people who have been vaccinated and doesn’t explain why myocarditis isn’t seen more broadly.

Jay Schneider, M.D., Ph.D., a consultant in cardiovascular medicine at the Mayo Clinic’s Jacksonville, Fla., campus, speculates that some of the mRNA in the vaccines might be taken up by cardiomyocytes, which are specialized heart cells. They then manufacture the spike protein, which could stimulate an antibody response against the cells. Schneider got heart cells to take up the Moderna vaccine in laboratory studies and then express the spike protein. Those results haven’t been published yet, and Schneider is cautious about the interpretation.

Yet another theory is that improper injection of the vaccines might be a factor. The injections should be into the deltoid (shoulder) muscle. But if the injection is accidentally into a vein, some of the vaccines might be delivered to the heart via blood vessels. A research study in Hong Kong that injected mice intravenously with the Pfizer-BioNTech vaccine resulted in both myocarditis and pericarditis in the animals.

And yet another theory focuses on the fact that myocarditis only seems to appear in male adolescents and young men. Bozkurt suggests that testosterone may play a role by increasing an inflammatory immune response. Alternately, Bozkurt notes in a study published in Circulation that underdiagnosis of cardiac disease in women may also be a factor.

Studies have hinted that the Moderna vaccine has a higher risk of myocarditis than the Pfizer-BioNTech. The difference hasn’t been confirmed, but the Moderna vaccine is given at a higher dose than the Pfizer-BioNTech vaccine, and Moderna’s chief executive officer Stéphane Bancel noted that if the difference is real, the dosing might be a factor. Some immunologists and vaccine experts have said the dose difference is probably one reason the Moderna vaccine is slightly more effective against COVID-19 with more durability than the Pfizer-BioNTech vaccine.

Vitamin D and Disease Prevention: Worth Another Look

 The use of vitamin D and omega-3 fatty acid supplementation was associated with a decreased likelihood of autoimmune disease in an ancillary analysis of a large randomized trial.

During 5 years of follow-up in a cohort of almost 17,000 adults, there were 123 incident cases of autoimmune disease among those who were taking vitamin D supplements daily, while there were 155 among those on placebo, for a hazard ratio of 0.78 (95% CI 0.61-1.00, P=0.045), reported Karen Costenbader, MD, of Brigham and Women's Hospital in Boston.

"I don't have to convince this audience of the burden of autoimmune diseases. These diseases affect 5% to 8% of the population, or 15 to 20 million Americans. They are among the top 10 causes of death among women under 65 in the U.S. and the second most common cause of chronic illness," she said in a plenary session at the 2021 virtual annual meeting of the American College of Rheumatology.

There currently is no means of preventing autoimmune diseases, which include conditions such as rheumatoid arthritis, polymyalgia rheumatica, and psoriasis.

Vitamin D is a pleiotropic hormone with wide regulatory actions. It binds to the nuclear vitamin D receptor and regulates an array of genes involved in innate and adaptive immune responses, she explained.

Ecological observations have demonstrated that autoimmune diseases such as inflammatory bowel disease, multiple sclerosis, and type 1 diabetes are more prevalent at northern latitudes where vitamin D levels typically are lower. In previous observational studies, high residential ultraviolet exposures have been associated with lower risks of Crohn's disease, and also with decreased rates of rheumatoid arthritis. However, no prospective trial has tested the effects of supplementation with vitamin D and the incidence of autoimmune disease over time.

Omega 3 fatty acids are abundant in fish. These compounds suppress the biosynthesis of inflammatory arachidonic acid-derived eicosanoids and regulate the inflammatory transcription factors nuclear factor kappa B and peroxisome proliferator activated receptor. Previous studies have found that higher intake of omega-3 fatty acids was associated with a lower incidence of rheumatoid arthritis and a decreased prevalence of seropositivity. To date, no prospective study has evaluated the effects of daily use of omega 3 fatty acids on the incidence of autoimmune disease.

To address these knowledge gaps, Costenbader's group analyzed data from the vitamin D and omega 3 (VITAL) trial, which included almost 26,000 men ages 50 and older and women 55 and older.

The primary analysis of VITAL was for the incidence of cancer and cardiovascular disease; no decrease in risk was observed for those conditions.

In this ancillary study, the outcome of interest was the incidence of all autoimmune diseases among the 16,956 participants who had undergone assays for 25 (OH) vitamin D and had plasma omega-3 index measurements.

First, participants were randomized to vitamin D, 2,000 IU/day (n=12,937) or placebo (n=12,937), and then in a 2 × 2 factorial design they were again randomized to omega 3 fatty acids, 1 g/day (n=6,468) or placebo (n=6,469) in the active vitamin D arm and to omega 3 fatty acids, 1 g/day (n=6,468) or placebo (n=6,469) in the placebo group of the vitamin D randomization arm.

Median follow-up was 5.3 years.

Participants' mean age was 67, and the groups were well matched on factors such as demographics, vitamin D levels and intake, and family history.

The cumulative incidence curves for vitamin D supplementation versus placebo begin to diverge after 2 to 3 years of follow-up, "which makes sense biologically and supports long-term use," she said.

For omega-3 supplementation, there were 130 confirmed cases of autoimmune disease in the active treatment group and 148 cases in the placebo group (HR 0.85, 95% CI 0.67-1.09, P=0.20). In an additional analysis comparing patients who had initially been randomized to the vitamin D placebo arm, there were 67 confirmed cases in the re-randomized omega-3 supplementation group and 88 in the placebo group (HR 0.74, 95% CI 0.54-1.03, P=0.07). In that analysis, there were 63 cases in the vitamin D plus omega-3 group and 88 cases in the placebo/placebo arm, for a hazard ratio of 0.69 (95% CI 0.49-0.96, P=0.03).

There were no significant differences in adverse events between the active and placebo groups.

"Supplementation for 5 years with vitamin D3 and/or omega-3 fatty acids reduced incident autoimmune disease by 25% to 30% in older adults versus those who received neither supplement," she concluded.

"The clinical importance of these findings is high, given that these are well tolerated, nontoxic supplements and that there are no other effective therapies to reduce the incidence of autoimmune diseases," she commented.

For Moderna, Inventing The Jab Was The Easy Part

 Moderna's stock crashed late last week as it was hit by disappointing vaccine sales and Pfizer's 'miracle' COVID pill news. Wall Street analysts panicked about a handful of factors, but while Moderna and its rivals managed to complete their groundbreaking vaccines in ten months (with government help, of course), inventing the vaccines actually wasn't the hardest part of the process.

Mass-producing enough jabs to innoculate the entire world (or, at least, the entire developed world) is a task of almost herculean proportions. And while Moderna rivals like Pfizer have factories already in place to produce various products already being sold by the pharma giant, Moderna and other rivals had to ramp up facilities on multiple continents and distributing the vaccine to countries around the world in the middle of a devastating pandemic.

But when Moderna revealed during its Q3 earnings that its FY2021 production target would be between 700MM and 800MM jabs, analysts - and by extension, investors - were none too pleased. It was this subpar sales guidance that, combined with the Pfizer news, that sent shares of the pharma contender (which had been relentlessly pumped on CNBC by investor Stephen Weiss) sliding.

That added to pressure on the stock that has been building for months. Since Aug. 9, Moderna has dropped 51%, wiping out almost $100 billion in market value.

Here's an example of Moderna's problem: the company says it has already produced enough bulk substance to create more than 900MM doses of its vaccine, which consists of messenger RNA coated in lipid nanoparticles.

However, Moderna apparently won’t be able to get all those doses into vials, where they need to be, before next year.

Speaking on a conference call with analysts, Moderna CEO Stephane Bancel tried to make the best of it, comparing the production delays to "teething problems" as Moderna attempts to expand from a "boutique" biotech firm in Cambridge, Mass. to a global vaccine distribution powerhouse.

To be sure, Moderna isn’t the first vaccine maker to run into production delay, which is why Moderna led shares of several vax-makers lower. J&J, AstraZeneca and Novavax lower after reporting Moderna's earnings. It seems like all vax makers, and their partners, have all hit production snags that have slowed rollouts of their vaccines at some point during the past year.

Novavax CEO Stanley Erck said in an interview Friday that his company had no factories of its own at the outset of the pandemic, and had to create a network of internal and external production facilities from scratch. Among other problems it encountered were shortages of things like filters and 4,000-liter bags needed for producing its vaccine in insect cells.

"Seemingly simple things ran out of global supply," Erck said. But now the problems are mostly solved and the company and its partners are able to produce 200MM doses a month by early next year.

Moderna has relied almost entirely on contract manufacturers to fill vials with its vaccine a process known as fill and finish.

As for the advantage enjoyed by Pfizer and BioNTech, long-term relationships with an extensive base of suppliers, as well as numerous supply-chain experts helping to plan for every possible contingency during production, were major assets for Pfizer and BioNTech, said Julie Swann, a health systems expert at North Carolina State University, which gave Pfizer a massive advantage over its rivals.

For example: Prior to the pandemic, Pfizer already had capacity to make 200MM vaccine doses a year, with 12 biologics and vaccine-manufacturing facilities in 10 countries. Moderna’s lone factory was a plant in Norwood, Mass., which had never produced anything at large scale before COVID.

The problems of scale are only going to get worse for Moderna, especially as it starts to ship more jabs abroad. Now, Moderna and its contractors have become major exporters of a heavily regulated drug. Each new market has its own set of rules that must be met and understood. Pfizer's global scale will make this somewhat easier.

But as one analyst said: “It’s not surprising that if someone had a problem, it would be [Moderna]," said Swann.
