When Amgen Inc. won approval of the oncolytic virus (OV) therapy Imlygic (talimogene laherparepvec, t-vec) for melanoma in late October 2015, hopes ran high for the space. The mood has since faded in some quarters – but hardly all.
Less than two months after scrubbing a phase III non-small-cell lung cancer trial of the bifunctional fusion protein immunotherapy bintrafusp alfa, Merck KGaA said a phase II test of the candidate in another indication, biliary tract cancer, has missed a predefined threshold that would have enabled a regulatory filing for it.

Kintor Pharmaceutical Ltd. said its androgen receptor (AR) antagonist, proxalutamide, reduced mortality risk by 92% and shortened median hospital length stay by nine days vs. standard of care, based on a preliminary analysis of phase III data from 590 hospitalized COVID-19 patients in Brazil.

Following the positive results, Kintor is seeking conditional approval in Brazil and will start another trial in critically ill patients in intensive care, she said.
The sad phase III fate of Abbvie Inc.’s rovalpituzumab tesirine, also known as rova T, in advanced small-cell lung cancer (SCLC) has not discouraged other drug developers targeting delta-like ligand 3 (DLL3) – not all of them, anyway.
Data from two Novavax Inc. clinical trials show its COVID-19 vaccine had 100% protection against severe disease, including hospitalization and death, paving the way for an emergency use authorization submission in the U.S. Mild and moderate COVID-19 was dramatically reduced in both studies, according to the data, and some efficacy was confirmed in variant strains.
