After a landmark clinical trial of the first POLQ inhibitor in cancer last year, a recently formed U.K. biotech is gearing up to bring a potential rival to the clinic in the coming months. Varsity Pharmaceuticals Ltd., of Cambridge, is planning to begin a phase I trial of novobiocin, a drug previously used as an antibiotic, which has also been found to inhibit the polymerase theta inhibitor (POLQ) pathway.
Researchers at Inserm have developed a method to direct pre-existing antibodies toward new targets. Their bimodular fusion proteins could be a broadly useful method for expanding access to antibody therapy. In a study that appeared in the Feb. 11, 2022, issue of Science Advances, the teams showed that antibodies to Epstein-Barr virus (EBV), which are present in 95% of the global population, could be redirected to a target cell of their choosing by fusing an EBV antigen to a cellular targeting ligand.
Marker Therapeutics Inc.’s update from the safety lead-in stage of its phase II study of MT-401 in treating post-transplant acute myeloid leukemia saw response in one of the six participants. The results from the study of the multitumor-associated antigen-specific T-cell product also known as zelenoleucel saw firms such as Oppenheimer cut its target price for Marker to $5 from $8 and Piper Sandler to cut its target price from $5.50 to $4.
Remix Therapeutics Inc., a company developing small molecules to manipulate RNA processing, stands to earn upward of $1 billion through a new strategic collaboration with Janssen Pharmaceutica NV. A Cambridge, Mass.-based startup, Remix last year patented new RNA splicing modulators. It will receive an initial payment of $45 million for research funding plus potential preclinical, clinical, commercial and sales milestone payments, and royalties. Janssen gains exclusive rights to three targets with applications in immunology and oncology.
