Clinical Catch-Up: June 28-July 2
It was another busy week for clinical trial news ahead of the July 4 holiday in the U.S. Here’s a look.
Five pharmaceutical companies in India, Cipla, Dr Reddy, Emcure, Sun Pharma and Torrent Pharma, announced plans to collaborate on a clinical trial of the oral anti-viral drug molnupiravir for mild COVID-19 in an outpatient setting in India. Between March and April, the five companies entered into a non-exclusive voluntary licensing deal with Merck Sharp Dohme (MSD) [Merck, in the U.S.], to manufacture and distribute molnupiravir to India and more than 100 Low and Middle-Income Countries (LMICs). They have since entered into a deal to jointly sponsor, supervise and monitor the trial in India. It is expected to run between June and September with about 1,200 patients. The drug is being developed by Merck (MSD) via a collaboration with Ridgeback Biotherapeutics in a Phase III trial for non-hospitalized patients with confirmed COVID-19.
Rigel Pharmaceuticals reported that its novel oral spleen tyrosine kinase (SYK) inhibitor, fostamatinib, had been chosen for a National Institutes of Health (NIH) ACTIV-4 (Accelerating COVID-19 Therapeutic Interventions and Vaccines) trial in hospitalized COVID-19 patients.

Altimmune provided an update on its AdCOVID investigational vaccine against COVID-19. The Phase I AdCOVID trial suggests the vaccine is well tolerated with an overall adverse event profile similar to intranasal saline placebo. The immunogenicity data was lower than expected, however. As a result, it is discontinuing further development beyond completing the Phase I trial.

CureVac reported final data for its COVID-19 vaccine, demonstrating 48% efficacy. It was a bit better at preventing symptomatic disease, at 53%, when the trial excluded people 60 years of age and older. In a June 16 readout, the figure was 47% overall. The company notes that the rise of more infectious variants has proven to be a headwind. The study involved approximately 40,000 adults in Europe and Latin America.
A University of Oxford study found that a third shot of the AstraZeneca-Oxford COVID-19 vaccine created a strong immune response. The vaccine is typically dosed twice, usually four to 12 weeks apart. The study, which has yet to be peer reviewed, was in 90 trial participants in Britain who were the earliest to receive doses in 2020. In March 2021, they received a third dose, about 30 weeks after their second. The third dose increased levels of antibodies against SARS-CoV-2 higher than seen a month after the second dose.
HDT Bio received the greenlight from the U.S. Food and Drug Administration (FDA) to proceed with a U.S.-based Phase I trial of its HDT-301 COVID-19 RNA vaccine.
