New drug combo targets rare, aggressive cancer in early trial

NCT ID NCT06132113

First seen Jun 27, 2026 · Last updated Jul 23, 2026 · Updated 4 times

Summary

This early-phase trial tests a new drug called BI 764532 (Obrixtamig) given together with standard chemotherapy for people with advanced neuroendocrine carcinoma (NEC), a rare and fast-growing cancer. The study involves about 55 adults whose tumors have a specific marker (DLL3). The main goals are to find a safe dose and see if the combination helps shrink tumors. Participants receive infusions of the drug plus chemo for up to 3 years if they benefit.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
BI 764532 (Obrixtamig) plus platinum-based chemotherapy (carboplatin or cisplatin) and etoposide
What this could lead to
If it works, this could point toward a new treatment option for advanced neuroendocrine carcinoma, a rare and aggressive cancer.
What could go wrong
This is an early Phase 1 trial with only 55 participants, so safety and dosing are the main focus. The combination may cause significant side effects, and it is too early to know if it will improve outcomes.
