ABOUT SPEVATAMIG
Spevatamig is a first-in-class native IgG-like bispecific antibody (bsAb) targeting claudin 18.2 and CD47. It was granted orphan drug designation (ODD) for the treatment of pancreatic cancer by the FDA in 2022 and was granted Fast Track designation for the treatment of patients with metastatic claudin 18.2-positive pancreatic adenocarcinoma in 2024. In 2023, Phanes entered into a clinical collaboration agreement with Merck (known as MSD outside the US and Canada) to study spevatamig in combination with Merck's anti-PD-1 therapy, pembrolizumab.

The US multi-center Phase 1/2 clinical trial of spevatamig (NCT05482893) is evaluating the safety, tolerability, pharmacokinetics, and preliminary efficacy of spevatamig in patients with advanced gastric, gastroesophageal junction, pancreatic ductal or biliary tract adenocarcinomas. The Phase 2 study of spevatamig has begun in China (CTR20241655).
