FDA Throws Up a Roadblock in Ocugen Gaining Approval for Bharat’s Covaxin Covid-19 Vaccine

Ocugen Faces Major Slowdown for COVID-19 Vaccine as FDA Recommends BLA
Ocugen just hit a major speed bump in what was expected to be its final turn in the COVID-19 vaccine race. The Pennsylvania-based eye disease company had to change its application from an Emergency Use Authorization to a full Biologics License Application (BLA) approval. The announcement comes right as Ocugen was finalizing its EUA application. The FDA decided for the company by recommending a BLA submission instead of a EUA for Covaxin. The agency also requested additional information beyond what was submitted. No further details on the data needed were given. Ocugen’s decision to join the race for a COVID vaccine was a bit of a surprise. A player in the ocular gene therapy world, the company was facing delisting from the NASDAQ in December of 2019. Joining forces with Indian vaccine developer Bharat Biotech bolstered Ocugen’s to stay in the game. Yesterday’s news may be a glimpse into why the FDA is recommending a BLA instead of the EUA fast lane the three vaccines currently approved in the US took. A study performed by endocrinologist Dr. Awadhesh Kumar Singh showed Ocugen-Bharat’s Covaxin did not stack up against a competing vaccine developed by the Serums Institute of India. Bharat Biotech questions the study’s validity and is launching a Phase IV study of real-world efficacy against COVID-19. According to the company, the Phase IV study would ensure that Covaxin “met every rigorous scientific standard for safety, effectiveness and manufacturing quality needed to support Emergency Use Authorization.” With millions of doses already given across India, sizeable data is anticipated soon. Today’s announcement certainly draws out the timeline for approval for Ocugen. The FDA can take six to ten months to approve a BLA. However, the current pandemic has shown they will stomp the gas for our current pandemic once the evidence of safety and efficacy is proven.

Ocugen’s CEO, Dr. Shankar Musunuri, said, “Although we were close to finalizing our EUA application for submission, we received a recommendation from the FDA to pursue a BLA path. While this will extend our timelines, we are committed to bringing COVAXIN to the US. This differentiated vaccine is a critical tool to include in our national arsenal given its potential to address the SARS-CoV-2 variants, including the delta variant, and given the unknowns about what will be needed to protect US population in the long term.” While final Phase III data is still coming, a second interim report shows a 78% efficacy against mild to moderate infection and 100% efficacy against severe COVID-19. The trial was the largest ever conducted in India, with 25,800 volunteers. Covaxin only needs regular refrigeration temperatures and is shipped ready-to-use, vital features for countries with limited access. This morning, India reported more than 6,000 COVID-19 deaths in a 24-hour period, the highest ever in the world. Less than 6% of the country’s massive population is fully vaccinated. Although securing a EUA for use in the US is now out of the picture, Ocugen will continue to move forward to secure full approval from the FDA, as well as a EUA in Canada. The company expanded rights for commercialization to include Canada earlier this month.

AstraZeneca antibody cocktail fails to prevent Covid-19 symptoms in large trial

AstraZeneca said a late-stage trial failed to provide evidence that the company’s Covid-19 antibody therapy protected people who had contact with an infected person from the disease, a small setback in its efforts to find alternatives to vaccines.

Astra antibody cocktail fails to prevent COVID-19 symptoms in large trial

(Reuters; )

June 15 (Reuters) – AstraZeneca (AZN.L) said on Tuesday a late-stage trial failed to provide evidence that its COVID-19 antibody therapy protected people who had contact with an infected person from the disease, a small setback in its efforts to find alternatives to vaccines.

The study assessed whether the therapy, a cocktail of two types of antibodies, could prevent adults who had been exposed to the virus in the past eight days from developing COVID-19 symptoms.

The therapy, AZD7442, was 33% effective in reducing the risk of people developing symptoms compared with a placebo, but that result was not statistically significant — meaning it might have been due to chance and not the therapy.

The Phase III study, which has not been peer reviewed, included 1,121 participants in the United Kingdom and the United States. The vast majority, though not all, were free of the virus at the start of the trial.

Results for a subset of participants who were not infected to begin with was more encouraging but the primary analysis rested on results from all participants.

“While this trial did not meet the primary endpoint against symptomatic illness, we are encouraged by the protection seen in the PCR negative participants following treatment with AZD7442,” AstraZeneca Executive Vice President Mene Pangalos said in a statement.

The company is banking on further studies to revive the product’s fortunes. Five more trials are ongoing, testing the antibody cocktail as treatment or in prevention.

The next one will likely be from a larger trial testing the product in people with a weakened immune system due to cancer or an organ transplant, who may not benefit from a vaccine.

TARGETED ALTERNATIVES

AZD7442 belongs to a class of drugs called monoclonal antibodies which mimic natural antibodies produced by the body to fight off infections.

Similar therapies developed by rivals Regeneron (REGN.O) and Eli Lilly (LLY.N) have been approved by U.S. regulators for treating unhospitalised COVID patients.

European regulators have also authorised Regeneron’s therapy and are reviewing those developed by partners GlaxoSmithKline (GSK.L) and Vir Biotechnology (VIR.O) as well as by Lilly and Celltrion (068270.KS).

Regeneron is also seeking U.S. authorisation for its therapy as a preventative treatment.

But the AstraZeneca results are a small blow for the drug industry as it tries to find more targeted alternatives to COVID-19 inoculations, particularly for people who may not be able to get vaccinated or those who may have an inadequate response to inoculations.

The Anglo-Swedish drugmaker, which has faced a rollercoaster of challenges with the rollout of its COVID-19 vaccine, is also developing new treatments and repurposing existing drugs to fight the virus.

AstraZeneca also said on Tuesday it was in talks with the U.S. government on “next steps” regarding a $205 million deal to supply up to 500,000 doses of AZD7442. Swiss manufacturer Lonza (LONN.S) was contracted to produce AZD7442.

Shares in the company were largely unchanged on the London Stock Exchange.

The full results will be submitted for publication in a peer-reviewed medical journal, the company said.

Former FDA Head Takes on Exec Role at Flagship’s Preemptive Health Initiative

 

Stephen Hahn, the Commissioner of the U.S. Food and Drug Administration (FDA) under former President Donald Trump, has taken on a new role as chief medical officer of a new health security initiative launched by Flagship Pioneering, a life sciences venture firm that incubates and curates biopharma companies.

First announced Monday, Flagship’s Preemptive Medicine and Health Security initiative aimed at developing products that can help people before they get sick. This division will focus on infectious disease threats and pursue bold treatments for existing diseases, including cancer, obesity, and neurodegeneration. 

In a brief statement, Hahn, who served as commissioner from December 2019 until January 2021, said the importance of investing in innovation and preemptive medications has never been more apparent. 

“In my career I have been a doctor and a researcher foremost and it is an honor to join Flagship Pioneering in its efforts to prioritize innovation, particularly in its Preemptive Medicine and Health Security Initiative. The more we can embrace a “what if …” approach the better we can support and protect the health and well-being of people here in the U.S. and around the world,” Hahn said in a statement. 

During his time at the FDA, Hahn was at the forefront of the government’s effort to battle the COVID-19 pandemic. His office oversaw the regulatory authorization of antivirals, antibody therapeutics and vaccines, as well as diagnostics and other tools to battle the novel coronavirus.

Hahn bore the brunt of verbal barbs aimed at the FDA by the former president for not rushing to authorize a vaccine for COVID-19 ahead of the November 2020 election. The second vaccine authorized by the FDA for COVID-19 was developed by Moderna, a Flagship company. 

Prior to his confirmation as FDA Commissioner, Hahn, a well-respected oncologist, served as chief medical executive of the vaunted The University of Texas MD Anderson Cancer Center. Hahn was named deputy president and chief operating officer in 2017. In that role, he was responsible for the day-to-day operations of the cancer center, which includes managing more than 21,000 employees and a $5.2 billion operating budget. He was promoted to that position two years after joining MD Anderson as division head, department chair and professor of Radiation Oncology. Prior to MD Anderson, Hahn served as head of the radiation oncology department at the University of Pennsylvania’s Perelman School of Medicine.

Flagship Founder and Chief Executive Officer Noubar Afeyan said the COVID-19 pandemic that shut down economies and caused the deaths of more than 3.8 million people across the world was an important reminder that health security is a top global priority. In addition, the ongoing pandemic brings into “stark focus” the importance of preemptive medications. 

Hahn, who helmed the FDA for three years and before that served as chief medical executive at The University of Texas MD Anderson Cancer Center, has extensive experience overseeing clinical and administrative programs. Afeyan said the new division would benefit from Hahn’s experience as FDA Commissioner and help steer the Preemptive Medicine and Health Security initiative as it explores Flagship’s “growing number of explorations and companies in this emerging field.”

It is not unusual for former FDA heads to take prominent roles with companies. For example, former FDA Commissioner Scott Gottlieb, Trump’s first FDA Commissioner, took a position on the Pfizer Board of Directors weeks after departing his government role. He has also taken positions on other boards since then, including Aetion, FasterCures and Illumina.

Five U.S. states had coronavirus infections even before first reported cases – study

Five U.S. states had coronavirus infections even before first reported cases – study

(Reuters) – At least seven people in five U.S. states were infected with the novel coronavirus weeks before those states reported their first cases, a new government study showed.

Participants who reported antibodies against SARS-CoV-2 were likely exposed to the virus at least several weeks before their sample was taken, as the antibodies do not appear until about two weeks after a person has been infected, the researchers said.

The latest results build on findings from a Centers for Disease Control and Prevention study that suggested the novel coronavirus may have been circulating in the United States last December, well before the first COVID-19 case was diagnosed on Jan. 19, 2020.

The positive samples came from Illinois, Massachusetts, Mississippi, Pennsylvania and Wisconsin, and were part of a study of more than 24,000 blood samples taken for a National Institutes of Health research program between Jan. 2 and March 18, 2020.

Samples from participants in Illinois were collected on Jan. 7 and Massachusetts on Jan. 8, suggesting that the virus was present in those states as early as late December.

“This study allows us to uncover more information about the beginning of the U.S. epidemic,” said Josh Denny, one of the study authors.

The findings were published in the journal Clinical Infectious Diseases.
