When combined with chemotherapy, the PD-1 inhibitor antibody toripalimab reduced the risk of death by 37% over chemotherapy alone when used first line in patients with recurrent or metastatic nasopharyngeal carcinoma, Coherus Biosciences Inc. revealed at this year’s American Society of Clinical Oncology meeting (ASCO).

The U.S. FDA has issued a final guidance for non-clinical performance testing for tissue containment bags used during power morcellation procedures, and the FDA had recommended in 2020 containment bags always be used during morcellation procedures. Despite the FDA’s advisory, a survey of surgeons published last year suggested that most of these procedures are not done with these containment systems, possibly because the rate of procedure-related complications is considerably higher when containment is used.

Freenome Inc. has acquired U.K.-based immunodiagnostics developer Oncimmune Ltd. for £13 million (US$16 million), in a move that bolsters Freenome’s frontline early cancer detection efforts. While Freenome has been largely focused on getting the U.S. FDA’s nod for its colorectal cancer test, Oncimmune already has a CE-IVD marked EarlyCDT Lung blood test, an autoantibody platform and an R&D pipeline of over seven cancer detection signals.

Exact Sciences Corp.’s long-term analysis of results from the Detecting cancers Earlier Through Elective mutation-based blood Collection and Testing (DETECT-A) study found that all patients diagnosed and treated for stage I or II cancers identified through its blood-based multi-cancer early detection (MCED) test remained cancer-free more than four years after diagnosis. Half of all the participants with cancer detected remained alive at four years, notable because most of the detected cancers had no recommended screening tests or standards. The results will be presented at the American Society of Clinical Oncology meeting June 2-6.
