Engineered CD40 Antibody Achieves Complete Cancer Remission in Phase 1 Trial
- A modified CD40 agonist antibody called 2141-V11 demonstrated remarkable efficacy in a phase 1 clinical trial, with six of 12 patients experiencing significant tumor reduction and two achieving complete remission.
- The drug showed systemic anti-tumor effects when injected directly into tumors, causing cancer disappearance at both injected and distant sites without the severe toxicities associated with previous CD40 therapies.
- Tissue analysis revealed the formation of tertiary lymphoid structures within tumors, creating immune-rich microenvironments that replaced cancerous tissue with organized immune cell aggregates.
- Nearly 200 patients are now enrolled in follow-up phase 1 and phase 2 trials investigating the drug's effectiveness against specific aggressive cancers including bladder cancer, prostate cancer, and glioblastoma.
