FDA authorization of vilobelimab signals new opportunities for drug developers in inflammatory diseases

The FDA has granted InflaRx (Nasdaq:IFRX) emergency use authorization (EUA) for the monoclonal antibody Gohibic (vilobelimab) to treat critically-ill COVID-19 patients. The company’s shares were up yesterday almost 84% to $3.77. Today, its shares jumped an additional 62% to $6.10.

The EUA represents a significant advance for the Jena, Germany–based company, which on March 31, 2022, encountered a setback related to the antibody. At that time, the company announced that vilobelimab failed a topline readout for critically ill intubated patients suffering from COVID-induced pneumonia in the phase 2/3 PANAMO study. Later, however, InflaRx reported in a predefined analysis without site-stratification that vilobelimab significantly decreased all-cause mortality at 28 days. While the initial protocol did not require site-stratification, the company amended the protocol based on regulators’ recommendations.

One of the ways that the COVID-19 pandemic had a profound impact on the pharma industry was how it highlighted the importance of pharmacovigilance. As personalized medicine gained traction, drug developers had to evolve their strategies to ensure safety and efficacy. In their report, “The Future of Pharmacovigilance,” Dr. Sabine Jeck-Thole and Ben Enejo, partners at Arthur D. Little, discussed the challenges and opportunities in this new landscape.

Embracing the shift in perception of adverse events and side effects

“When we heard about adverse events and side effects, it was not bad news,” Jeck-Thole said in an interview. “It indicated that we understood our drug or vaccine much better than without any safety information.” She emphasized that this shift in perception was essential for the industry as it moved towards pharmacovigilance in personal…

Pfizer and BioNTech secure FDA nod for omicron-adapted COVID-19 booster for kids under 5

COVID-19 vaccine developers Pfizer (NYSE:PFE) and its partner BioNTech (Nasdaq:BNTX) have won emergency use authorization (EUA) for a single booster dose of their omicron BA.4/BA.5-adapted bivalent COVID-19 booster for kids between 6 months and 4 years of age.

The booster can be administered at least two months after completing the primary vaccination series with three doses of the original Pfizer-BioNTech COVID-19 vaccine. Additionally, FDA has authorized the bivalent vaccine for use as the third dose in a primary series for the same age group. The agency, however, has not yet authorized a fourth booster dose.

Trial data Supports bivalent vaccine safety and efficacy

The EUA is based on data from substudies within the companies’ Phase 1/2/3 trial (NCT05543616) evaluating the safety, tolerability and immunogenicity of a fourth bivalent vaccine dose in 300 children aged 6 months to 4 years. A subset of 60 study participants within the same age group demonst…

Researchers at the University of Houston are using glow-in-the-dark materials to enhance the sensitivity of rapid COVID-19 home diagnostics.

The widely used lateral flow assay provides rapid results for diagnostics such as at-home COVID-19 or pregnancy tests. They also offer low costs and ease of operation. Test results on LFA diagnostics come through in colored lines.

“We are making those lines glow-in-the-dark so that they are more detectable, so the sensitivity of the test is better,” said Richard Willson, who’s leading the University of Houston team.

Willson is the Huffington-Woestemeyer professor of chemical and biomolecular engineering at the UH Drug Discovery Institute and a professor of biochemic…

This T-cell vaccine could be the future of COVID-19 protection

The current mRNA vaccines from Moderna (Nasdaq:MRNA) and Pfizer (NYSE:PFE)/BioNTech (Nasdaq:BNTX) stimulate the production of neutralizing antibodies that bind to the spike protein of SARS-CoV-2.

But there is a novel mRNA vaccine that activates T cells to attack cells infected with the virus. Developed by researchers at MIT and other institutions, the new vaccine could sidestep the need for updated boosters based on currently circulating variants.

In a preclinical study published in Frontiers in Immunology, the T-cell vaccine successfully attacked cells infected with the virus rather than activating the part of the immune system that releases neutralizing antibodies. In addition, the researchers tested the vaccine in humanized mice and successfully generated both CD8+ (cytotoxic) and CD4+ (helper) T-cell responses.

This new MIT-T-COVID vaccine could …

We still don’t fully understand why the SARS-CoV-2 virus is so transmissible and causes severe disease in some people but not others.

But Dr. Philip Adamson, chief medical officer of Abbott’s heart failure business, said he’s amazed by how quickly we’re learning about COVID-19, building off our prior knowledge of coronaviruses and other viral pathogens.

“We have more of a handle on the mechanisms, and that’s where I think we are beginning to have hope for clarity,” he said. “In just about every disease that we are able to treat, we develop those treatments because we understand the fundamental mechanism of the disease.”

Adamson warned of increasing rates of heart and lung failure due to COVID-19 when Medical Design & Outsourcing interviewed h…

Dual defense: FluGen’s M2SR vaccine shields against influenza and COVID-19

[Image courtesy of Adobe Stock]

For many years, vaccine developers have known that several problems with current influenza vaccines – short-lived serum antibodies, lack of immunity at the site of infection, and lack of robust protection against drifted strains – contribute to their modest efficacy. Although new approaches to influenza vaccine design, manufacture and administration have been explored, none has yielded an approved vaccine that addresses all of these problems.

mRNA COVID-19 vaccines have saved millions of lives worldwide since their approval, and their importance in combatting the pandemic cannot be overemphasized. However, these vaccines are already facing the same problems as influenza vaccines. Because they protect against illness but not infection, vaccinated individuals who contract the SARS-CoV-2 virus can still shed and transmit it.

To better control both viruses and the illnesses th…

FDA extends shelf life of some popular COVID tests

[Image courtesy of Abbott]The FDA announced today that certain COVID-19 diagnostic tests under emergency use authorization now have a longer shelf life.

Diagnostics made by Abbott, Maxim Biomedical and iHealth Labs all received extensions for their expiration dates.

The Abbott BinaxNow COVID-19 antigen self tests now have a shelf life of 22 months. Previously, the popular test had a 15-month shelf life.

Pfizer seeks EUA for omicron booster for under-5 kids

Pfizer (NYSE: PFE) and its COVID-19 vaccine partner BioNTech (Nasdaq: BNTX) today announced they’ve submitted a EUA application with the FDA for an omicron COVID-19 booster for children under 5.

The companies are seeking authorization for their omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine as the third 3-µg dose in the three-dose primary series for children 6 months through 4 years of age.

The U.S. is presently grappling with a “tripledemic” of COVID-19, flu and RSV, which can each cause respiratory distress in children. Pfizer and BioNTech said today that updated COVID-19 vaccines may help prevent severe illness and hospitalization.

If authorized, children in this age group would still receive a primary series consisting of two 3-µg doses of the original Pfizer-BioNTech COVID-19 vaccine. After that, they would receive a third 3-µg dose of the omicron BA.4/BA.5-adapted bivalent vaccine.

Pfizer and BioNTech are seeking a sim…
