It was a particularly busy week for clinical trial news, in part because of several big medical conferences. Here’s a look.

COVID-19-Related
AstraZeneca announced that its Farxiga (dapagliflozin) failed to hit the endpoints in its Phase III DARE-19 study in hospitalized COVID-19 patients at serious risk of developing complications. It also failed to assist hospitalized patients with recovery. The drug is a first-in-class, oral, once-daily SGLT2 inhibitor approved by the FDA to decrease the risk of hospitalization for heart failure in type 2 diabetes and with cardiovascular disease or multiple cardiovascular risk factors.
Regeneron Pharmaceuticals announced the results from its Phase III trial of recently infected asymptomatic COVID-19 patients for its REGEN-COV (casirivimab with imdevimab) antibody cocktail. The therapy decreased the overall risk of the patients progressing to symptomatic COVID-19 by 31%, which was the primary endpoint of the trial. It also decreased the overall risk of progression by 76% after the third day. In addition, REGEN-COV decreased the duration of symptoms and significantly reduced viral levels.
Regeneron also reported results from a second trial of REGEN-COV, this trial evaluating the combination therapy’s ability to decrease the risk and burden of COVID-19 infection among household contacts of SARS-CoV-2 infected individuals. This was jointly run with the National Institute of Allergy and Infectious Diseases (NIAID). The trial hit both primary and key secondary endpoints, demonstrating the antibody cocktail decreased the risk of symptomatic infections by 81% in people who were not infected when they began the trial. On average, people receiving the antibody therapy who had symptomatic infection resolved their symptoms in one week, compared to three weeks with placebo.
Rigel Pharmaceuticals announced positive topline results from its Phase II trial of fostamatinib for hospitalized patients with COVID-19. The drug is an oral spleen tyrosine kinase (SYK) inhibitor.
Romark announced initial results from its Phase III trial of NT-300 (nitazoxanide extended-release tablets, 300 mg) for mild or moderate COVID-19. A median time to sustained response was similar for patients receiving NT-300 compared with placebo, but in mild disease, sustained response was decreased by 3.1 days. It also hit a secondary endpoint, demonstrating an 85% reduction in progression to severe disease. Nitazoxanide was originally developed to treat intestinal protozoan infections caused by Cryptosporidium parvum and Giardia lamblia. It also has broad-spectrum antiviral activity.
Inovio reported interim data from its Phase I study of its COVID-19 vaccine, saying it induced a robust T-cell response against multiple variants, both the Brazil and UK variants. The data came from clinical samples from the study. The vaccine, INO-4800, is made up of an optimized DNA plasmid and delivered directly into cells via a proprietary smart device.
Merck indicated it was moving its molnupiravir into the Phase III part of the Phase II/III MOVE-OUT study in outpatient COVID-19 patients based on a planned interim analysis from the Part II part. However, the Phase III portion in hospitalized patients will not proceed because the data suggests the drug is unlikely to demonstrate a clinical benefit in that patient population. Molnupiravir is an oral antiviral candidate.
The I-SPY COVID Trial, sponsored by Quantum Leap Healthcare Collaborative (QLHC) announced that, in addition to the razuprotafib and apremilast arms, the icatibant portion of the trial has concluded. Icatibant, which is marketed by Takeda as Firazyr for hereditary angioedema (HAE), was unlikely to impact critically ill COVID-19 patients. It was chosen because it is an antagonist of the bradykinin type 2 receptor, which may be involved in respiratory impairment in COVID-19. The I-SPY COVID Trial is a Phase II study in critically ill COVID-19 patients receiving high flow oxygen or mechanical ventilation.
Non-COVID-19-Related
