New clinical data for ANKTIVA immunotherapy in lung cancer, a study on EBV-driven resistance via ADAR1 RNA editing, and research on microbiome metabolites modulating immunotherapy response were presented at major conferences and in recent publications.
The FDA has cleared CStone Pharmaceuticals' investigational new drug application to begin a Phase II trial of its trispecific antibody CS2009 in advanced solid tumors. The multicenter trial will evaluate monotherapy and combination regimens across nine cancer types in Australia, China, and the U.S. Initial Phase I data showed a favorable safety profile and encouraging antitumor activity.
The phase 3 RAMPART trial updated results show adjuvant durvalumab monotherapy did not significantly improve disease-free survival in resected renal cell carcinoma, while the durvalumab plus tremelimumab combination showed benefit in high-risk patients. Real-world treatment decisions are also shaped by patient-specific factors.
The FDA granted Fast Track designation to COYA 302 for ALS. Phase 1 data showed tolerability and biomarker effects, and the phase 2 ALSTARS trial is underway.
European biotechs are exploring new immunotherapy targets beyond PD-1/PD-L1, including BTLA, TIGIT, and SLAMF6. Lund University researchers discovered a SLAMF6-mediated immune evasion mechanism. BioNTech and GenMab are advancing next-generation ICIs and bispecific antibodies through strategic partnerships.
The global cancer monoclonal antibodies market was valued at USD 66.7 billion in 2025 and is expected to reach USD 135.2 billion by 2033. Growth is being driven by targeted therapies, bispecific antibodies, ADCs and checkpoint inhibitors.
Studies on immune checkpoint inhibitor therapy found pretreatment biomarkers strongly predicted checkpoint inhibitor-associated autoimmune diabetes, while hyperglycemia during treatment was common and did not worsen disease progression.
Early results from stage I of the phase 3 PRESERVE-003 trial showed gotistobart improved overall survival versus docetaxel in previously treated metastatic squamous NSCLC. Objective response rate and duration of response also favored gotistobart, while progression-free survival did not differ significantly.
Adagene and Incyte will collaborate on a Phase 1 study combining muzastotug with INCA33890 for MSS colorectal cancer patients, beginning in 2026. The collaboration marks the second instance where Adagene's SAFEbody technology is paired with a PD-1-based bispecific. Muzastotug has shown encouraging response rates in combination with pembrolizumab in previous trials.
Recent publications and collaborations advance glioblastoma research through blood-based microRNA diagnostics, combination immunotherapy trials, and identification of MOV10 as a prognostic biomarker and therapeutic target.
