Specifically, the company highlighted that the global multi-center Phase II clinical trial for its core pipeline asset, CS2009 (a PD-1/VEGF/CTLA-4 trispecific antibody), is progressing smoothly.
Plans are in place to release the latest clinical data in the upcoming interim results announcement and at the 2026 European Society for Medical Oncology (ESMO) annual congress.
Furthermore, the company intends to engage with the U.S. Food and Drug Administration (FDA) before the end of this year to discuss the protocol for a Phase III global multi-center registration study (MRCT), aiming to initiate the first batch of global Phase III MRCT trials.
In a separate move during June 2026, the company itself repurchased a cumulative total of 4,597,000 shares, with all repurchased shares slated for cancellation.
This share buyback initiative is seen as a clear demonstration of the company's firm belief in its own long-term business growth.
