Minhua Chu: Novel Claudin18.2-Targeting ADC Drug for Pancreatic Cancer

Minhua Chu, Managing Partner at TransitionValue Partner, shared a post on X:

“Innovent Biologics has registered a Phase III clinical trial for its novel Claudin18.2-targeting ADC drug, IBI343, for the treatment of pancreatic cancer.

The trial, titled G-HOPE-002, plans to enroll 201 patients with advanced pancreatic cancer. IBI343 features a differentiated design. The ADC technology originates from a collaboration with Synaffix and utilizes glycan-mediated site-specific conjugation, with a drug-to-antibody ratio (DAR) of 4. It employs a highly internalizing antibody and incorporates Fc silencing mutations.

In July, Innovent officially disclosed the molecular structure of IBI343 (Arcotatug tavatecan).

The Ph1 results of Innovent’s anti-CLDN18.2 ADC, IBI343, in the treatment of advanced G/GEJ AC are published in Nature Medicine.

Based on these data, IBI343 has initiated an international multicenter Phase 3 clinical study (G-HOPE-001, NCT06238843) in 2024.”
