Spevatamig (PT886) as Monotherapy or in Combination With Chemo and/or Targeted Therapy and/or ICI, for the Treatment of Patients With Advanced Gastrointestinal Cancers, Including Gastric, Gastroesophageal Junction, Pancreatic Ductal or Biliary Tract Carcinomas (the TWINPEAK Study)
A Phase 1/2, Open-Label, Dose Escalation and Expansion Study With PT886 Followed by a Multi-cohorT Study in Patients With Advanced Gastrointestinal Cancers, Including GastrIc, Gastroesophageal JuNction, Pancreatic Ductal or Biliary Tract AdEnocarcinomas of PT886, in Combination With ChemotherApy, Targeted Therapy, and/or an Immune ChecKpoint Inhibitor. The TWINPEAK Study
This is a first-in-human, Phase 1/2, open-label, dose escalation and dose expansion and combination study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of Spevatamig (PT886). Patients with the following tumor types will be eligible for screening: unresectable or metastatic gastric adenocarcinoma, gastroesophageal junction (GEJ) adenocarcinoma, biliary tract carcinoma (BTC), pancreatic ductal adenocarcinoma (PDAC) and colorectal carcinoma (CRC).
