[GEN has updated this list. See GEN’s COVID-19 DRUG & VACCINE CANDIDATE TRACKER, a comprehensive collection of news, milestones and updates on more than 200 drug and vaccine candidates currently being developed for the COVID-19 pandemic.]
As the world scrambles to monitor and contain the COVID-19 outbreak, drug companies are racing to develop or repurpose treatments to combat the potential pandemic. The death toll continues to climb. The first U.S. death associated with the SARS-CoV-2 virus was reported in Washington state February 29. As of March 2, according to the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University, 3,048 people in 11 countries had died worldwide, nearly all of them (96% or 2,914) in China.
CSSE also reported 89,198 confirmed cases in 67 countries, including 80,026 (90%) in China and 86 in the U.S. Of those confirmed cases, just over half (45,175) have recovered.
A new survey by Genetic Engineering & Biotechnology News (GEN) reveals 35 active drug development programs in North America, Europe, and China. Those 35 include treatments that have received the greatest public attention in recent days, being developed by companies that range from pharma giants like GlaxoSmithKline and Sanofi, to small and large biotechs such as Moderna and Gilead Sciences. Gilead has begun clinical trials in China after peer-reviewed journals showed its antiviral candidate, remdesivir, having positive results in a case involving an American patient and Chinese in vitro tests.
China’s status as the center of the SARS-CoV-2 outbreak is reinforced by a statistic tucked at the bottom of a report published February 28 by the state-run Xinhua news agency: Of 234 clinical trials registered with the Chinese Clinical Trial Registry, nearly half (105) focus on treatments for COVID-19.
Many of those trials are included in the 60 studies listed in ClinicalTrials.gov whose descriptions include the term COVID-19, as well as the seven studies whose descriptions include SARS-CoV-2. The U.S. website lists 331,715 trials in 209 countries.
In the Xinhua report, Wu Yuanbin, director-general of Science and Technology for social Development with China’s Ministry of Science and Technology (MOST), announced the publication of guidelines for clinical studies of drugs and vaccines intended to combat the deadly viral outbreak. The guideline gives priority to drugs that are already marketed, and whose efficacy has been proven in animal and in vitro studies.
Yet repurposing existing drugs is just one proverbial arrow in the quiver of drug developers and health agencies worldwide, as seen in GEN’s A-List of top 35 treatments under development and/or clinical study for COVID-19, as disclosed by drug developers and/or authorities in recent weeks. Because some of the experimental treatments have yet to be named, or identified, each prospective treatment is listed by its developer, followed by the treatment name or description, the type of treatment including its mechanism, and a brief status update summarizing recent developments.
Where applicable, the status updates include links to recent news reports in GEN, as well as to clinical trials pages maintained by U.S. authorities via ClinicalTrials.gov, and by Chinese authorities as the Chinese Clinical Trial Registry.
In many cases, Chinese authorities, hospitals, and companies are studying potential treatments outside the auspices of their original developers. The First Hospital of Changsha and the Second Xiangya Hospital of Central South University are primary sponsors partnering with Hu’nan Haiyao hongxingtang Pharmaceutical Co. on a clinical trial assessing the combination of Beijing Genova Biotech’s Novaferon, a recombinant interferon alpha (IFN-α) like viral protein launched in 2018 to treat hepatitis B, and AbbVie’s Kaletra® (See above) in eliminating SARS-CoV-2 in patients with COVID-19. The trial has been prospectively registered with Chinese authorities. (ChiCTR2000029496).
Another example: Pirfenidone—an idiopathic pulmonary fibrosis drug marketed by Roche and its Genentech subsidiary as Esbriet®—will be studied in patients with severe and critical COVID-19, under a planned randomized, open-label clinical trial that has been prospectively registered by Tongji Hospital of Tongji Medical College, part of Huazhong Science and Technology University (ChiCTR2000030333).
Two other recent coronavirus-related collaborations focus on potential targets. The Israeli Institute for Biological Research, a government research institute, said February 25 it will explore the potential of Dyadic International’s C1 gene expression platform to express gene sequences and targets developed by the Institute into an rVaccine candidate and monoclonal antibodies for treating COVID-19. A day earlier, Cocrystal Pharma agreed to license proprietary broad-spectrum antiviral compounds for COVID-19 and norovirus from Kansas State University Research Foundation. Cocrystal’s technology is designed to generate a 3D structure of inhibitor complexes at near-atomic resolution, enabling the company to identify novel binding sites.
And at least one collaboration announced January 28 focuses on a platform with the promise of future treatments: AbCellera said it and partners will apply its pandemic response platform to develop field-ready medical countermeasures within 60 days of isolation of an unknown viral pathogen. Those partners include researchers at the Vaccine Research Center at the NIH’s National Institute of Allergy and Infectious Diseases (NIAID).
This list is certain to multiply in coming weeks as global health agencies, governments, and drug developers step up efforts against the SARS-CoV-2 virus.
Treatment: Kaletra® (also marketed as Aluvia; lopinavir/ritonavir)
Type: HIV-1 protease inhibitor indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in adults and children 14 days old and older.

The Health Commission of Henan Province announced January 31 that three confirmed cases of patients diagnosed with new coronavirus infections recovered after taking Kaletra, a combination of ritonavir and lopinavir. As of that date, nucleic acid testing of more than 20 confirmed cases of patients infected with new coronavirus, admitted to hospitals in Zhejiang Province turned negative after taking Kaletra, according to Ascletis Pharma, which is evaluating a combination therapy of its own candidates ASC09 and ritonavir (See below).
Treatment: Ampligen® (rintatolimod)
Type: Immune modulator indicated for severe chronic fatigue syndrome
Status: AIM ImmunoTech said February 27 it is partnering with ChinaGoAbroad, a matchmaking and advisory service for cross-border deals involving China, to facilitate talks with China’s government to allow entry of AIM’s drug candidate Ampligen into China for use as a prophylactic/early-onset therapeutic against COVID-19. The companies are pursuing approval for trials in China, and FDA authorization under regulations allowing the export of investigational drugs for use in a sudden and immediate national emergency. Through those rules, AIM won FDA authorization to import Ampligen into Argentina in 2019 as a treatment for severe chronic fatigue syndrome.

Status: Moderna said February 24 that it shipped the first batch of mRNA-1273 to the NIH’s National Institute of Allergy and Infectious Diseases (NIAID) for use in a planned Phase I study in the U.S. The primary aim of the Phase I open-label, dose-ranging trial study (NCT04283461), which had yet to recruit patients at deadline, is to evaluate the safety and reactogenicity of a 2-dose vaccination schedule of mRNA-1273, given 28 days apart, across 3 dosages in healthy adults. Moderna designed the vaccine in collaboration with investigators at the NIAID Vaccine Research Center (VRC).
Treatment: Antiviral therapy based on company’s novel nanomedicines platform.
Type: Broad-spectrum virus-binding ligand: “It is like a ‘Venus-Fly-Trap’ for the virus,” says Anil R. Diwan, PhD, President and Executive Chairman.
Status: NanoViricides confirmed January 30 that it was developing a COVID-19 treatment, stating that it “already found some lead candidate ligands in its chemical library” that can bind to the SARS-CoV spike protein just as it binds to cognate receptor ACE2.
NanoViricides’ technology relies on copying the human cell-surface receptor to which the virus binds, and making ligands that chemically attach to a nanomicelle, to create a nanoviricide®. When a virus comes in contact with the nanoviricide, the nanomicelle polymer is designed to fuse with the virus lipid envelope.
The company said it has started preparing for testing of potential candidates in cell cultures against “low-threat” coronaviruses, including ones that use the ACE2 receptor, in its own BSL-2 virology laboratory at its Shelton, CT, campus. NanoViricides added that it is working on developing collaborations to advance its COVID-19 program should an effective drug candidate be identified.
Treatment: Vaccine candidate to be selected
