Pfizer Inc. may be the first to apply for food approval
The New York-based company may have knowledge of its Phase 3 clinical trials for the COVID-19 vaccine through the end of October, a critical step before federal approval, but the timing of submission to the FDA will depend on when the federal firm publishes its rules for presenting knowledge of COVID-19 or SARS-CoV-2 vaccine trials , which have not yet been made public, said Jerica Pitts, Pfizer’s spokesman.
“I don’t really need to wait,” Jerica Pitts said, when asked if Pfizer could simply submit his knowledge and seek FDA approval until October or early November. “Even if we have a reading, let’s not say we know it because the FDA hasn’t published what those criteria are. “
The vaccine evolved through Pfizer and BioNTech, founded in Germany, as well as evolving through Moderna Inc. , founded in Cambridge, Massachusetts, are the highest complex in Phase 3 clinical trials among corporations competing to locate a vaccine to fight COVID-19. Peter Pitts, president of the Center for Public Interest Medicine and former associate commissioner of the FDA, said.
“There will be more than one approved,” Pitts noted, adding that a number of new vaccines will be sent for FDA approval in the coming months.
Moderna CEO Stéphane Bancel once announced last week that the company would seek FDA approval for its candidate vaccine until at least November 25 to allow more time to monitor the protection of trial participants.
Meanwhile, Pfizer has already invested $87 million to reconfigure its Kalamazoo operation for the first vaccine production, said Chaz Calitri, acting director of the Kalamazoo site. The company would almost double its spending for a moment later, he added.
“(We continue to) hope that the effectiveness of our test verification will be read as soon as late October,” Jerica Pitts told the Detroit News.
Kalamazoo’s investment is a component of Pfizer’s $2 billion commitment to expanding a coronavirus vaccine, which the company says remains at risk because it does not yet have a product. simply get up to 500 million additional doses, according to Pfizer.
Pfizer and Moderna are looking for what would be the first vaccines based on mRNA technology or messenger RNA, Pitts said, which is a safe, less expensive and faster way to produce a vaccine. Detroit and elsewhere.
Phase 3 trials for the vaccine evolved through AstraZeneca and Oxford University, based on a weakened bloodless virus that infects chimpanzees and includes genetic clothing similar to SARS-CoV-2, were discontinued in the United States last month after a player became ill. Tests have resumed in Britain, Peter Pitts said.

Despite the clinical network’s skepticism that a vaccine can be obtained so quickly, President Donald Trump has continually said that a vaccine may be in a position on Election Day. Pfizer is one of nine major pharmaceutical corporations that have pledged not to do so. cut corners in the race to create a vaccine.
Dr. Anthony Fauci, the country’s leading infectious disease physician, said a vaccine was unlikely to be available until November 3, but that’s not impossible. The director of the National Institute of Allergy and Infectious Diseases also said a vaccine may be obtained faster than expected if trials yield incredibly positive results.
Pfizer, who has not lately seen the effects of his Phase 3 trials, expects to know the knowledge as soon as the end of October, but in the meantime, only a small committee of researchers has the knowledge.
“We don’t need to get into politics of that,” said Jerica Pitts of Pfizer. “Lately we’re running to make sure we don’t take shortcuts. We focus on power and safety. “
Once you own the data, Pfizer will temporarily compare it before passing it on to the FDA. The federal company will perform its own analysis, although it is also likely to name an advisory committee of external experts to compare the vaccine.
“The advisory committee’s resolution does not bind the FDA,” Pitts said. “The FDA makes its own resolutions, sometimes following the recommendation of its advisory committee. “
Between Pfizer and Moderna, Pitts, the former FDA associate, said Pfizer would possibly have the best chance of obtaining advance FDA approval due to his long delight in the agency’s approval procedure. Moderna’s lack of pleasure in obtaining FDA drug approval “could potentially slow down his procedure with his data,” he said.
“Pfizer knows exactly what to do and has been very involved in his knowledge communications,” he said.
At the end of FDA approval, Pfizer expects to produce one hundred million vials until the end of the year between the Kalamazoo plant and a plant in Puurs, Belgium, classified to supply European supply. The two factories would produce 1. 3 billion by 2021.
To increase production to this level, Pfizer would raise around 500 jobs in Kalamazoo, two hundred of whom have already been hired, said Calitri, plant manager.
The company also recently expanded its check protocol to reach 44,000 people, 47% more than its original 30,000-person check plan. The expansion allows Pfizer to raise 16- and 17-year-olds and come with a more varied combination of Pfizer has registered 31,000 participants in the United States, parts of Europe, Argentina, Brazil, South Africa and elsewhere.
“We have been working on the COVID candidate vaccine for Pfizer since March 20 Array . . . so we’ve been there for six months,” said Calitri, plant manager at Kalamazoo. “Many things have happened over the past six months to prepare us in case we succeed in reading the effects of our clinical trials.
The 1,300-acre Kalamazoo is Pfizer’s largest production facility, with 3,000 workers generating active pharmaceutical ingredients, prescription drugs, and medical devices. The company plans to manufacture the COVID-19 vaccine without interruption from its other source lines, Calitri added.
More than 60 leading bioethics researchers and specialists sent a letter on September 25 to Pfizer asking the company to wait at least until last November before the FDA approved its vaccine.
The letter, first reported through Bloomberg News, indicated that Pfizer will need to monitor participants for at least two months after the injection of the two-dose vaccine before asking the FDA to sign it. November before seeking approval, the scientists wrote.
Kamlendra Singh and a team of researchers from the University of Missouri recently learned 3 express mutations of the COVID-19 virus that have evolved since the first instances of COVID-19 were known in China and said they would have signed the letter if it had. I knew he was being sent.
Mutations known through their team coexist in each case of COVID-19 in the United States and may play a role in their infectious nature, according to the peer-reviewed study published on September 15 in the Journal of Neuroimmune Pharmacology.
Singh argued that mutations may be only to blame for the resurgence of COVID-19 in Europe, where mutations are widespread. Although mutations have been discovered in 3 cases of viruses in China, a new spread can lead to a resurgence there, he added. .
“It’s all over the world,” Singh said of mutations, “and it wasn’t like that in mid-March. We that these 3 mutations in combination made the virus more persistent. “
When asked how to expand a vaccine at a time when there is still much to report on the virus, Singh said, “It is very difficult to expand a vaccine opposed to a mutated virus. “
“Let’s hope corporations don’t take shortcuts and (not) they’re offering something that’s not enough,” he said. “While these corporations have combined and committed to doing nothing to make these vaccines dangerous.
“So it’s a difficult situation. “
Pfizer and Moderna are using a vaccine based on RNA or mRNA messages. If developed through any of the companies, it would be the first mNS-founded vaccine for inactivated coronavirus.
Messenger RNA is a long, single-strand molecule that carries genetic commands to produce one or more proteins that help the framework generate a imaginable immune reaction to a vaccine.
“The price of the mNSA generation is that it is safer; it does not use any live virus,” said Peter Pitts, former associate commissioner of the FDA. “It is faster to manufacture and also faster to scale from a virtual point of view and it is cheaper. “
Pfizer took a step forward in the progress of his vaccine, as he partnered with BioNTech for two years to create an mNRN-based influenza vaccine, according to the company’s spokeswoman.
With traditional vaccines, a piece of inactivated virus, called an antigen, is injected into the body, identifying it as a toxin or foreign body, which causes the body’s immune formula to produce express antibodies to fight the invader and prepare for the next time it finds the pathogen.
With the Pfizer vaccine, the mNA is injected into the body, where it enters mobiles and provides commands to produce antigens. When the mobile presents antigens to the body’s immune system, it triggers the production of T-mobiles and antibodies to fight infection.
“You don’t have to inject any facets of the virus into the frame,” Peter Pitts said. “What you inject into the human frame are necessarily instructions to (create the antibodies) you need to produce. “
DNA, the style required to manufacture the mRN vaccine, will be manufactured in a mobile growing procedure at a Pfizer facility in St. Louis, where it will be purified, filtered and sent to the company’s production facility in Andover, Massachusetts. DNA will be incubated with mAA building blocks, an enzyme procedure to create mRN.
Kalamazoo will get mNRA and raw tissues and mix them with the vaccine.
“We are the last level of the relay race,” said Calitri, the plant manager.
The Kalamazoo facility is well placed to adopt the assignment, as it is already expanding its ability to produce vaccines and other liquid drugs stored in vials, said Ron Kitchens, executive director of Southwest Michigan First, the Kalamazoo-based regional economic progression company.
“Michigan’s competitive credit for getting those jobs for which Pfizer already had the amenities under structure to produce, compared to generating them in its European amenities,” Kitchens said, adding that the company began expansion about 3 years ago.
“They didn’t know they were going to do this (COVID-19 vaccine), but they knew that injectables were the long-term administration of medicines because it is much safer, it is much more effective, so the moment matches perfectly compared to Europe, where the vast majority of other vaccines will be manufactured. “
The history of the pfizer region goes back to the founding of Upjohn through Dr. William E. Upjohn in 1886, Kitchens said.
“Today, those amenities and this company are under the Pfizer brand, yet Kalamazoo is the largest pharmaceutical plant in the United States,” he said, noting that Perrigo, one of the country’s leading generic drug manufacturers, is about 10 miles from Kalamazoo in Allegan County.
“Just keep making sure the can is still made in Michigan. “
Production of Pfizer’s COVID-19 vaccine in Kalamazoo would be a major financial aid to the region, Kitchens said.
“Especially jobs where you don’t think like trades,” he said.
Calitri, the plant manager, said many stalls will be in spaces like packaging and labeling that don’t require prior experience. Kitchens expect part of the work to pass on to others who can train at work.
Some other people on the network will move to better-paid jobs in Pfizer, leaving their old vacancies for others to fill, he said.
“Each task will create more for others,” Kitchens said. “This creates a food chain in the grid because they buy so much, their electricity consumption increases. It’s a virtuous circle. “
