Despite the arrival of FDA-approved tissue-agnostic targeted cancer therapies, there is increasing recognition that the response of tumors that are driven by the same oncogene differs according to their location.

Jazz Pharmaceuticals plc's acquisition of Redx Pharma plc's pan-RAF inhibitor program for treating RAF- and RAS-mutant tumors was rocket fuel for Redx's stock (AIM:REDX), which closed 108% higher than it opened, offering some relief for the struggling company.

Revolution Medicines Inc., a California-based company developing a small-molecule inhibitor of SHP2 in partnership with Sanofi SA and other programs targeting mutant forms of the key signaling protein RAS, has raised a $100 million series C equity financing led by Boxer Capital LLC, an investment firm funded by British businessman Joe Lewis' Tavistock Group, which has backed financings of companies including G1 Therapeutics Inc., Kura Oncology Inc. and, more recently, Encoded Therapeutics Inc.

Merck & Co. Inc. has tapped Skyhawk Therapeutics Inc. for its expertise in the discovery and development of small molecules that modulate RNA splicing, agreeing to pay it up to $600 million per program target plus royalties on sales of any commercialized products of the collaboration.

Despite a February adcom meeting urging the agency to wait for more data, the FDA has approved Karyopharm Therapeutics Inc.'s selinexor, in combination with dexamethasone (dex), as a new treatment for certain adults with relapsed refractory multiple myeloma (MM).

Boston Biomedical Inc. shuttered phase III study Canstem111P of napabucasin for patients with metastatic pancreatic ductal adenocarcinoma, adding to the list of studies that have fallen in pancreatic cancer.

The Warburg effect – the marked preference of tumors for fueling themselves via anaerobic metabolism – was described more than 90 years ago. Otto Warburg won the Nobel Prize for his discovery in 1931, and research into the phenomenon long dominated the field of tumor metabolism. Over the past decade, however, there has been increased attention to the fact that tumor metabolism is deregulated in multiple ways beyond the Warburg effect.
