The race to develop better antivirals for COVID-19 is heating up after Pfizer Inc. and Merck & Co. Inc. pushed ahead with clinical development of late-stage candidates, while Rigel Pharmaceuticals Inc. announced encouraging midstage data.

Although COVID-19 is still dictating how things are done in the U.S. and throughout the world, the FDA looked beyond the pandemic in an update to its guidance on conducting clinical trials of medical products during the public health emergency.
Pfizer Inc. reported on Aug. 30, 2021, that its JAK inhibitor, abrocitinib, beat Dupixent (dupilumab, Regeneron Pharmaceuticals Inc./Sanofi SA) in a head-to-head study of patients with moderate to severe atopic dermatitis. In the JADE DARE study, a higher percentage of patients taking abrocitinib had a 4-point improvement in the severity of Peak Pruritus Numerical Rating Scale (PP-NRS4) from baseline to week two compared to Dupixent.
Questions regarding rates of cytokine release syndrome (CRS) cropped up during Poseida Therapeutics Inc.’s conference call on preliminary data from nine patients in the company’s phase I trial of P-PSMA-101, an autologous CAR T product candidate to treat patients with metastatic castrate-resistant prostate cancer (mCRPC).
Higher antibody titer levels were found in participants receiving two doses of Moderna Inc.’s COVID-19 vaccine compared to those receiving the Pfizer Inc.-Biontech SE vaccine, according to a research letter published in JAMA.
A closely watched phase IIb test of JNJ-9220, an investigational HIV vaccine regimen developed by Johnson & Johnson's Janssen Vaccines & Prevention BV, has been stopped because the regimen provided insufficient protection against HIV infection. Though safe, the candidate's efficacy was just 25.2%, according to statisticians who analyzed data from the study, called Imbokodo. Further analysis of the study will continue, and the study was deemed to have provided sufficient data for further immunological correlates research, according to J&J.
Clinical updates, including trial initiations, enrollment status and data readouts and publications: Bayer, Bone, Daiichi, Janssen, Kinnov, Lysogene, Nrx, Pfizer, Regeneron, Sanofi, Uniqure.
DUBLIN – AC Immune SA and partner Genentech reported Aug. 31 that their Tau-targeting antibody, semorinemab, brought about a dramatic 43.6% reduction in cognitive decline vs. baseline in a phase II trial in patients with mild to moderate Alzheimer’s disease. The effect was statistically significant (p<0.0025) and is clinically meaningful. Indeed, it represents the biggest single treatment effect ever reported in a clinical trial in this population of Alzheimer’s patients and sets the stage for an extensive phase III program that could set the agenda for Alzheimer’s research for the foreseeable future.
New data from Nrx Pharmaceuticals Inc.’s phase IIb/III trial for treating acute respiratory failure due to critical COVID-19 showed that Zyesami (aviptadil) improved the lung’s ability to transmit oxygen within a day of administration. The respiratory distress ratio’s average difference between those participants receiving aviptadil and placebo was clinically meaningful and statistically significant. The benefit was found across participants, all baseline severities and hospitals of all types.
