Regeneron Pharmaceuticals Inc. proposes to buy Checkmate Pharmaceuticals Inc. though an all-cash price of $10.50 per share for about $250 million. That’s pretty much on target with Checkmate’s April 19 closing share price (NASDAQ:CMPI) of $10.35, as the stock gained a staggering 326% on the day.
Bristol Myers Squibb Co.’s relatlimab will hit the market as the first U.S. FDA-approved LAG-3 inhibitor, cleared by the agency for use in a fixed-dose combination with Opdivo (nivolumab) to treat adult and pediatric patients with unresectable or metastatic melanoma. The approval, a day ahead of the March 19 FDA target date, adds another type of immune checkpoint inhibitor to the oncology arsenal, which already includes drugs targeting PD-1/PD-L1 and CTLA4.
Four years after Bristol Myers Squibb Co.’s (BMS) $1.85 billion investment in Nektar Therapeutics Inc., the pair’s collaboration has stumbled mightily with a phase III failure. A first analysis their melanoma study, PIVOT IO-001, showed it missed three primary endpoints. The study of interleukin-2-targeting NKTR-214 (bempegaldesleukin) combined with Opdivo (nivolumab) compared to Opdivo monotherapy as a first-line treatment for previously untreated, unresectable or metastatic melanoma did not meet the primary endpoints of progression-free survival and objective response rate.
Oncorus Inc. offered initial safety, tolerability and immune activation and clinical response data from its ongoing phase I trial with ONCR-177 at the Society for Immunotherapy of Cancer (SITC) meeting. In the fully enrolled and completed surface lesion, dose-escalation part of the study, single-agent ONCR-177, an oncolytic herpes simplex virus for intratumoral injection, proved well-tolerated with no dose-limiting toxicities.
It’s been a decade since the first checkpoint inhibitors were approved, but the problem of low response rates remains in many forms of cancer. Highlight Therapeutics SL, of Valencia, Spain, hopes to change all that with an approach that primes the body to become more responsive to immunotherapies.
Shares of Ultimovacs ASA (OSE:ULTI) climbed 16.6% to NOK148.60 (US$17.82) on news the FDA will expedite an eventual review of its investigational cancer vaccine, UV-1, in combination with checkpoint inhibitors for the potential treatment of unresectable or metastatic melanoma.
In studies that give new insights into both developmental biology and the origins of melanoma, investigators at Memorial Sloan-Kettering Cancer Center and Weill Cornell Medical College have identified the activity of chromatin remodeling protein ATAD2 as necessary for cells with the oncogenic mutation V600E to give rise to melanomas. Involvement of epigenetic factors in cancers, or their targeting, is not new in cancer – as HDAC inhibitors as well as newer drugs such as the EZH2 inhibitor Tazverik (tazemetostat, Epizyme Inc.) demonstrate. But to Richard White and his colleagues, the point of their work is not so much about individual targets.

LONDON – Endomag Ltd. has received endorsement from the U.K. health technology assessment body NICE, opening the way to broader adoption of its Magtrace non-radioactive cancer staging technology in the National Health Service, and providing backing for commercialization of the system in other markets.
Oncohost Ltd. has opened eight U.K. trial sites in the study assessing the ability of its artificial intelligence (AI)-driven proteomics profiling technology to single out which cancer patients will respond to treatment with immune checkpoint inhibitors. The sites will carry out proteomic analyses of blood samples from patients with late-stage melanoma or non-small-cell lung cancer (NSCLC), to predict their likely response to immunotherapy.
