New Dual-Action antibody enters first human trials for Hard-to-Treat cancers

NCT ID NCT07660432

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early-phase study tests a new drug called SIM0689 in adults with advanced solid tumors that have stopped responding to standard treatments. SIM0689 is a bispecific antibody designed to block two cancer-promoting pathways (PD1 and VEGF). The trial will first find a safe dose, then expand to see if it shrinks tumors in specific cancer types.

Active substance
SIM0689 (a bispecific antibody targeting PD1 and VEGF)
What this could lead to
If successful, this could point toward a new treatment option for people with advanced solid tumors that have not responded to standard therapies.
What could go wrong
This is a very early Phase 1 trial, so the drug may not be safe or effective. Side effects are unknown, and only a small number of participants will receive the optimal dose.
