A novel pharmacologically targetable metabolic mechanism driving resistance to epidermal growth factor receptor (EGFR)-targeting tyrosine kinase inhibitors (TKIs) has been identified in preclinical models of lung cancer in a Chinese study led by scientists at Shanghai Jiao Tong University School of Medicine.
Researchers have retrospectively divided more than 16,000 non-small-cell lung cancer (NSCLC) patients with EGFR mutations into four structure-based subgroups, and looked at how the members of each subgroup fared depending on which EGFR inhibitor they were given.

Hongyun Biotech Co. Ltd. raised ¥100 million (US$15.5 million) in a series B round to move its new generation EGFR inhibitor, RC-01, to the IND stage in China and the U.S. for non-small-cell lung carcinoma (NSCLC). The plan is to finish the IND filing by the end of this year and start the trial in 2022.
Diamedica Therapeutics Inc.’s chief medical officer, Harry Alcorn, said that “due to the complexity [of diabetic kidney disease (DKD)], there's not a clear answer” as to why such patients did less well in the company’s Redux phase II trial with DM-199 (recombinant human tissue kallikrein 1 [KLK1]). “But I wouldn't say that there wasn't a response in the DKD group,” he said, citing upside in 30% of subjects.
Shares of Cullinan Oncology Inc. (NASDAQ:CGEM) rose 11.3% to close at $33.11 on June 4 as an update on its EGFR inhibitor, CLN-081, suggested it may prove competitive with Johnson & Johnson's recently approved treatment, Rybrevant (amivantamab), for adults with non-small-cell lung cancer (NSCLC) whose tumors bear EGFR exon 20 insertion mutations.
Bad regulatory news didn’t quash hopes for Travere Therapeutics Inc. with sparsentan, its dual-acting antagonist of the endothelin type A and angiotensin II type 1 receptors for focal segmental glomerulosclerosis (FSGS), a disease of kidney scarring.
The bad cohort 1 news from Spectrum Pharmaceuticals Inc. in late April with poziotinib in the phase II Zenith20 study turned itself around in a stock-boosting way as the Henderson, Nev.-based firm unveiled data from cohort 2.
It is equally fair to say that lung cancer treatment has come a long way, and that it has a long way to go. Speaking at a joint conference by the International Association for the Study of Lung Cancer and the American Association for Cancer Research on lung cancer translational research, William Pao remembered the stark realities of being an oncology fellow at Memorial Sloan-Kettering Cancer Center just 20 years ago, when the main lung cancer “procedure” done by trainees was to get a DNR, or do-not-resuscitate order, from their patients.
