LONDON – Natural killer (NK) cell therapy specialist Onk Therapeutics Ltd. has raised $21.5 million in a series A, enabling it to move three lead programs into proof-of-concept animal testing and to progress manufacturing and scale-up of its cord blood-derived cells.

Clonal hematopoiesis of indeterminate potential (CHIP) was associated with a 35% reduced risk of Alzheimer's disease (AD) in studies presented at the plenary session of the American Society of Hematology (ASH) annual meeting on Sunday.

Another drug from the emerging menin inhibitor drug class has hit safety issues, after the FDA put an early stage acute myeloid leukemia trial of Kura Oncology Inc.’s KO-539 on partial clinical hold because of a patient death. The news from Kura follows safety issues that emerged from Syndax Pharmaceuticals Inc.’s rival SNDX-5613, where an issue with QT prolongation emerged in at least 5% of patients in otherwise encouraging phase I/II trial results announced in April.

A phase III trial of Rafael Pharmaceuticals Inc.’s devimistat in pancreatic cancer has failed, sending shares in its publicly listed holding company through the floor. Shares in Rafael Holdings (NYSE:RFL) closed Oct. 28 down 73% to $8.09, for a loss of $22.08 after an independent data monitoring committee also recommended a separate phase III trial of devimistat in acute myeloid leukemia should be stopped due to lack of efficacy.

Targeted therapies are a classical example of a glass that can be seen as half full or half empty.

While Aprea Therapeutics Inc.’s data disclosed July 21 from the phase II trial with eprenetapopt – also known as APR-246, a reactivator of mutant tumor suppressor protein p53 – plus azacitidine (AZA) whetted interest in taking aim at the “guardian of the genome,” the company’s fortune took an unexpected turn when the FDA smacked a partial clinical hold on work with the duo.

Advaxis Inc.’s long journey is ending happily by way of a merger with Biosight Ltd. that leaves the new firm with $50 million to help advance aspacytarabine (BST-236), a prodrug of cytarabine for acute myeloid leukemia and myelodysplastic syndromes.

San Diego-based Biotheryx Inc. has raised $92 million in series E financing led by Farallon Capital Management to advance multiple molecular glues, proteolysis-targeting chimeras and monovalent degraders toward the clinic. Its first molecular glue program, BTX-1188, is expected to enter the clinic by the end of this year.

Charlene Liao, Immune-Onc Therapeutics Inc.’s CEO told BioWorld she has a solid plan for using the company’s new $73 million series B1 and B2 financing. “It is time to go beyond T cells and to consider myeloid checkpoints as the next wave of cancer immunotherapies,” she said. Immune-Onc will use the funding to target myeloid checkpoints, especially leukocyte immunoglobulin-like receptor subfamily B, as it continues to develop its blood cancer and solid tumor therapies.
