BioNTech, a German company that collaborates with Pfizer from the United States, has announced its progress in obtaining the COVID-19 vaccine.

Pfizer chairman Dr Albert Bourla said the results of the first set of Phase 3 COVID-19 vaccine trials provide early evidence that the vaccine has the potential to cure infections.

“Today is a great day for science and humanity. The results of the first set of our Phase 3 COVID-19 vaccine test provide early evidence of our vaccine’s ability to prevent COVID – 19, ”reads an excerpt from Dr Albert’s report.

He said with new records for epidemics, high-capacity hospitals and economies struggling to reopen, they are reaching an important milestone in developing the vaccine against the epidemic at a time when the world is most in need.

“With today’s news, we are an important step in delivering much needed improvements to people around the world to help put an end to this global health crisis. We look forward to sharing additional performance and safety data generated from thousands of participants. In the coming weeks.”

Meanwhile, the third phase of clinical trials of BNT162b2 began on July 27 and registered 43,538 participants, 38,955 of whom received the second dose of the vaccine candidate until November 8, 2020.

According to Professor Ugur Sahin, co-founder and CEO of BioNTech, the first interim analysis of the Global Phase 3 study provides evidence that the vaccine can effectively prevent COVID-19.

“The first interim analysis of our Global Phase 3 study provides evidence that a vaccine can effectively inhibit COVID-19. It is a breakthrough in innovation, science and global collaboration,” he said.

This comes at a time when the coronavirus continues to rise worldwide with confirmed cases hitting 50,891,706 by Monday afternoon. Of these, a total of 35,879,529 have recovered from the virus and 1,264,205 have been infected.

PFIZER AND BIONTECH ANNOUNCE VACCINE CANDIDATE AGAINST COVID-19 ACHIEVED SUCCESS IN FIRST INTERIM ANALYSIS FROM PHASE 3 STUDY

“Today is a great day for science and humanity. The first set of results from our Phase 3 COVID-19 vaccine trial provides the initial evidence of our vaccine’s ability to prevent COVID-19,” said Dr Albert Bourla, Pfizer Chairman and CEO. 

“We are reaching this critical milestone in our vaccine development program at a time when the world needs it most with infection rates setting new records, hospitals nearing over-capacity and economies struggling to reopen. 

With today’s news, we are a significant step closer to providing people around the world with a much-needed breakthrough to help bring an end to this global health crisis. We look forward to sharing additional efficacy and safety data generated from thousands of participants in the coming weeks.”

After discussion with the FDA, the companies recently elected to drop the 32-case interim analysis and conduct the first interim analysis at a minimum of 62 cases.

Upon the conclusion of those discussions, the evaluable case count reached 94 and the DMC performed its first analysis on all cases. 

The case split between vaccinated individuals and those who received the placebo indicates a vaccine efficacy rate above 90%, 7 days after the second dose. This means that protection is achieved 28 days after the initiation of the vaccination, which consists of a 2-dose schedule.

As the study continues, the final vaccine efficacy percentage may vary. The DMC has not reported any serious safety concerns and recommends that the study continue to collect additional safety and efficacy data as planned. The data will be discussed with regulatory authorities worldwide.

“I want to thank the thousands of people who volunteered to participate in the clinical trial, our academic collaborators and investigators at the study sites, and our colleagues and collaborators around the world who are dedicating their time to this crucial endeavor,” added Bourla.

“We could not have come this far without the tremendous commitment of everyone involved.”

The new covid vaccine BNT162b2

“The first interim analysis of our global Phase 3 study provides evidence that a vaccine may effectively prevent COVID-19. This is a victory for innovation, science and a global collaborative effort,” said Prof. Ugur Sahin, BioNTech co-founder and CEO.

“When we embarked on this journey 10 months ago this is what we aspired to achieve. Especially today, while we are all in the midst of a second wave and many of us in lockdown, we appreciate even more how important this milestone is on our path towards ending this pandemic and for all of us to regain a sense of normality. 

We will continue to collect further data as the trial continues to enrol for a final analysis planned when a total of 164 confirmed COVID-19 cases have accrued. I would like to thank everyone who has contributed to making this important achievement possible.”

The Phase 3 clinical trial of BNT162b2 began on July 27 and has enrolled 43,538 participants to date, 38,955 of whom have received a second dose of the vaccine candidate as of November 8, 2020. 

Approximately 42% of global participants and 30% of U.S. participants have racially and ethnically diverse backgrounds.

The trial is continuing to enrol and is expected to continue through the final analysis when a total of 164 confirmed COVID-19 cases have accrued.

The study also will evaluate the potential for the vaccine candidate to protect COVID-19 in those who have had prior exposure to SARS-CoV-2, as well as vaccine prevention against severe COVID-19 disease.

In addition to the primary efficacy endpoints evaluating confirmed COVID-19 cases accruing from 7 days after the second dose, the final analysis now will include, with the approval of the FDA, new secondary endpoints evaluating efficacy based on cases accruing 14 days after the second dose as well.

The companies believe that the addition of these secondary endpoints will help align data across all COVID-19 vaccine studies and allow for cross-trial learnings and comparisons between these novel vaccine platforms. The companies have posted an updated version of the study protocol at https://www.pfizer.com/science/coronavirus.

Pfizer and BioNTech are continuing to accumulate safety data and currently estimate that a median of two months of safety data following the second (and final) dose of the vaccine candidate – the amount of safety data specified by the FDA in its guidance for potential Emergency Use Authorization – will be available by the third week of November. 

Additionally, participants will continue to be monitored for long-term protection and safety for an additional two years after their second dose.

Along with the efficacy data generated from the clinical trial, Pfizer and BioNTech are working to prepare the necessary safety and manufacturing data to submit to the FDA to demonstrate the safety and quality of the vaccine product produced.

Based on current projections they expect to produce globally up to 50 million vaccine doses in 2020 and up to 1.3 billion doses in 2021.

Pfizer and BioNTech plan to submit data from the full Phase 3 trial for scientific peer-review publication.
