26 Companies Racing to Develop the Most Promising Coronavirus Vaccines and Drugs

Anne ChouFeatures


As the novel coronavirus continues to spread across the globe, pharmaceutical giants and smaller biotech companies worldwide are racing to develop effective vaccines and treatments to stem the pandemic. To date, there are no approved vaccines to prevent infections by this coronavirus, or specific drugs to treat them, so speed in development, testing and approval of vaccines and treatments for the disease is critical.

The urgent search for a solution to the coronavirus crisis has companies working on three primary fronts – developing a vaccine to provide immunity to the disease, creating new medicines specifically to treat or prevent coronavirus infections, and repurposing existing drugs to be used as a treatment for patients with COVID-19, the disease caused by the virus.

Companies that are working on experimental vaccines are leveraging a range of innovative technologies, such as DNA, mRNA and adenovirus vector vaccine platforms, that allow for a faster and lower-cost vaccine development process in response to a viral outbreak.

Three of the most promising vaccines are being developed by U.S. biotech firm Moderna, China’s CanSino Biologics, and Johnson & Johnson. CanSino jumped ahead of others in the race to develop a coronavirus vaccine when it announced plans last week to start a Phase 2 clinical trial of its experimental vaccine in China.

The vaccine candidates being developed by Moderna and Johnson & Johnson are among those that have been fast-tracked by the U.S. Department of Health and Human Services (HHS). The Biomedical Advanced Research and Development Authority (BARDA), a division of HHS, will help foot the bill, speed up clinical trials, and provide expertise for the selected companies working with the agency.

Cambridge, MA-based Moderna saw its experimental vaccine enter human trials in record time on March 16, just nine weeks after Chinese authorities released the genetic sequence of SARS-CoV-2, the novel coronavirus. The company, which went public in 2018 in the largest-ever biotech IPO, specializes in an innovative messenger RNA (mRNA) vaccine technology. This approach delivers the virus’s genetic code into the body, which then instructs the cell machinery to create the proteins needed to fight off the virus itself.

Johnson & Johnson, the world's biggest pharmaceutical company, announced that its Janssen unit has identified a lead vaccine candidate utilizing the same technologies used to make its experimental Ebola vaccine. J&J will jointly contribute $1 billion toward its COVID-19 vaccine effort in partnership with the federal government's BARDA, with the goal of supplying one billion vaccine doses worldwide for emergency pandemic use by early 2021.

Companies such as Eli Lilly and Regeneron Pharmaceuticals are working on developing entirely new treatments for COVID-19, while also attempting to repurpose drugs originally designed for other diseases, such as arthritis, malaria and HIV, to treat coronavirus patients. Already approved drugs could provide the fastest path to fighting COVID-19 since doctors already know what are the expected side effects and how safe they are for people, whereas researchers creating new drugs are starting from scratch.

The decades-old generic malaria drug hydroxychloroquine has made headlines in recent weeks for its potential to help with treating COVID-19 based on earlier anecdotal reports from China and France. However, there’s no solid evidence yet that hydroxychloroquine works in treating or preventing the disease. A recent small-scale Brazilian research trial of chloroquine, which is related to hydroxychloroquine, was abruptly halted for safety reasons after putting some COVID-19 patients at a higher risk of potentially fatal heart complications.

In the U.S., a nationwide trial is underway around hydroxychloroquine as a potential therapy for COVID-19. The drug has yet another opportunity to prove its effectiveness against the disease in the World Health Organization’s (WHO) unprecedented large-scale global trial, called Solidarity, which was unveiled last month to test the most promising treatments, including hydroxychloroquine and chloroquine.

When will a coronavirus vaccine or treatments for the disease be ready?

Developing new vaccines and drug treatments takes time and a vast amount of money. Extensive testing in clinical trials is needed to see if new vaccines and drugs are both safe and effective before they can gain regulatory approval.

The vaccine development process has traditionally been measured in years and even decades. But, progress in vaccine development is now occurring at an unprecedented speed, and new technological advances have taken years off the traditional development timeline.

Some experts predict that an approved coronavirus vaccine could be 12 to 18 months away. However, the most promising option for quickly finding a way to manage the COVID-19 global health emergency is repurposing existing drugs, with a number of them now in late-stage clinical trials to test their efficacy for COVID-19.

Companies Developing Coronavirus Vaccines & Drugs

A number of pharmaceutical giants such as Pfizer and GlaxoSmithKline are teaming up with smaller biotech firms to accelerate development, testing and manufacturing capabilities by providing funding and sharing expertise and technologies. These private company partnerships can be crucial to putting a vaccine or treatment on the market as quickly as possible.

Government agencies and international organizations are also collaborating with companies to tackle the pandemic, including the WHO, BARDA, the National Institute of Allergy and Infectious Diseases (NIAID), and the Coalition for Epidemic Preparedness Innovations (CEPI), an Oslo-based nonprofit founded in 2017 by the governments of Germany, Japan and Norway, the Bill and Melinda Gates Foundation, and others to address a gap in vaccine development funding after the Ebola and Zika virus outbreaks.

One of the largest public-private efforts is being coordinated by CEPI. The organization has invested almost $30 million to date in eight projects and companies, including Moderna, Inovio Pharmaceuticals, and CureVac. All three companies are working on innovative genetic vaccines that are potentially faster to develop than traditional vaccine processing, which requires the laborious production of viral proteins or actual viruses. But, it is still an unproven technology. There are no FDA approved mRNA or DNA vaccines for any disease, so the coronavirus crisis is an opportunity for these technologies to be tested far more quickly than they would have otherwise

“Nature has invented mechanisms to activate our immune system against infectious diseases. With our unique messenger RNA technology, we mimic nature and give our body the information how to fight against the virus,“ said Dr. Mariola Fotin-Mleczek, CureVac’s chief technology officer.

It’s a crowded race with dozens of companies across the globe working on vaccines and drugs, as the coronavirus pandemic continues to ravage the world around us. The number of cases worldwide has passed 2,000,000 and deaths are approaching 130,000, according to John Hopkins University.

The jury is still out on which vaccines and drugs will cross the finish line. While a vaccine is the best way to prevent disease spread since healthy people are protected from becoming infected in the first place, the option that is most likely to save lives in the shortest amount of time is to repurpose existing drugs for other diseases, or develop new drugs to treat and prevent infection.

Here is a list of 26 companies that are working on some of the most talked-about efforts to treat or prevent COVID-19 based on our review of the current research and development efforts. The companies are listed in order of which treatments and vaccines are furthest along in the development pipeline based on the latest information, starting with those in Phase 2/3 clinical trials, followed by Phase 1 clinical trials, and then preclinical development efforts.
