Several drugmakers saw shares fall after earnings missed expectations. Alnylam's Amvuttra sales disappointed despite growth; Neurocrine's guidance underwhelmed; AbbVie's Imbruvica and Roche's Vabysmo fell short of consensus.
Clinical trials show a pancreatic cancer drug nearly doubles survival, a head-and-neck therapy shrinks tumors, and new research explains drug resistance. Cancer mortality is falling in the US and UK.
A rare BTK A428D mutation causes resistance to all BTK-targeted therapies, finds a new study. China is reviewing the first CAR-T therapy for gastric cancer, and research reveals why BET inhibitors fail and targets AML's DNMT3A mutation.
Six-year SEQUOIA trial data show zanubrutinib sustains a progression-free survival advantage (74% vs 32%) over bendamustine-rituximab in CLL without del(17p). Benefit extends to high-risk del(17p) patients.
The U.S. FDA has accepted for filing a New Drug Application for tirabrutinib under the accelerated approval pathway for relapsed or refractory primary central nervous system lymphoma, setting a PDUFA action date of December 18, 2026. The submission is supported by Phase 2 PROSPECT study results showing a 67% overall response rate and 44% complete response rate. If approved, tirabrutinib would be the first BTK inhibitor commercially available in the U.S. for this indication.
Long-term results from the phase III TRIANGLE trial show ibrutinib-based regimens improve survival in younger mantle cell lymphoma patients, while the ECHO trial establishes a new standard for older patients. Advances in CAR T-cell and bispecific antibody therapies are reshaping treatment for this rare blood cancer. The findings were presented at the annual MCL Consortium meeting.
