A trio of European cancer vaccine specialists have filed progress reports, with advances in technology and targeting, fresh infusions of cash, and off-the-shelf products moving into the clinic. Six years on from its formation, Ervimmune closed a series A at €17 million (US$19.9 million) to drive forward clinical development of lead program Ervac-01. Accession Therapeutics Ltd. raised a further £30.5 million (US$40.4 million) from its existing investors, following dosing of four patients with Trocept-01. And Infinitopes Ltd. added $15.4 million to its seed round, as it finalizes preparations for a phase I/IIa trial of the lead product ITOP-1.
Immune checkpoint inhibitor therapy has proven effective against many types of solid tumors, but not many subtypes of ovarian cancer, including the rare subtype of ovarian clear cell carcinoma (OCCC). Now, researchers have identified a subtype of OCCC that involves inactivating mutations in the gene PPP2R1A and that responds well to immune checkpoint inhibitor therapy.
Researchers at the Fred Hutchinson Cancer Research Center found that autoantibodies targeting the exoproteome reshaped checkpoint inhibitor responses and opened new avenues to enhance immunotherapy. In the study published in the July 23, 2025, issue of Nature, the authors set out to address a long-standing question in cancer immunotherapy: why patients with the same type of cancer, treated with the same immunotherapy, can experience such drastically different outcomes.
Taiwan’s Hanchorbio Inc. is out-licensing its breakthrough checkpoint inhibitor, HCB-101, to Shanghai Henlius Biotech Inc. in a deal worth more than $200 million.
Researchers in the U.K. have overthrown the orthodox view that childhood cancers have a low mutation burden, opening up new drug targets and opportunities for repurposing existing therapies. In particular, a high mutation rate is associated with a response to cancer immunotherapy. But although PD-1 checkpoint inhibitors are approved for treating pediatric cancers with a high level of microsatellite instability mutations, in general it is thought childhood tumors are not amenable to immunotherapy.

Tilt Biotherapeutics Ltd. has raised $25.6 million in a series B round that will fund phase II development of the lead oncolytic virus in the treatment of platinum-resistant ovarian cancer.
Ellipses Pharma Ltd. has agreed to in-license global rights to GENA-104, a first-in-class immuno-oncology monoclonal antibody that targets CNTN4, from Genome & Co. Ltd. Targeting CNTN4 is a new approach that blocks the CNTN4-APP checkpoint interaction on T cells, promoting tumor cell killing, with potential use in cancers that respond poorly to conventional checkpoint inhibitors.
Ottimo Pharma Ltd. is equipped to file an IND and take its lead bifunctional antibody into phase II development, after closing a $140 million series A. The round will accelerate development of jankistomig, which targets the PD-1 immune checkpoint whilst inhibiting tumor angiogenesis by neutralizing vascular endothelial growth factor (VEGF).
A year after manufacturing issues resulted in a complete response letter for cosibelimab, the U.S. FDA approved Checkpoint Therapeutics Inc.’s drug, branded Unloxcyt, as the first anti-PD-L1 antibody for use in metastatic or locally advanced cutaneous squamous cell carcinoma patients who are not candidates for curative surgery or curative radiation.
