New targeted drug shows promise for hard-to-treat stomach and pancreatic cancers
NCT ID NCT06219941
First seen Jun 27, 2026 · Last updated Jul 30, 2026 · Updated 2 times
Summary
This study tests a new drug called AZD0901, alone or with other cancer treatments, in people with advanced solid tumors that have a specific protein called CLDN18.2. The goal is to see if the drug is safe and can shrink tumors. About 224 adults with stomach, pancreatic, or bile duct cancers that have not responded to standard therapy will participate.

Sub study 2 Specific Inclusion criteria: * Participants diagnosed with histologically confirmed metastatic or advanced PDAC. * Availability of an archival sample or a fresh tumour biopsy taken at screening. * No prior treatments for unresectable or metastatic disease. Prior neoadjuvant/adjuvant chemotherapy is permitted as long as participants progressed ≥ 6 months (183 days) from the last dose. Sub study 3 Specific Inclusion criteria * Histologically confirmed, unresectable advanced, or metastatic adenocarcinoma of biliary tract, including cholangiocarcinoma (intrahepatic or extrahepatic) and gallbladder carcinoma (NOTE: Ampullary cancers are not eligible). * Documented radiographic or clinical disease progression on or after at least one prior regimen and maximum 2 prior lines of systemic treatment for unresectable or metastatic disease. Master Exclusion Criteria applicable to all sub studies: * Unstable or active peptic ulcer disease or digestive tract bleeding including but not limited to clinically significant bleeding in the setting of prior CLDN18.2 directed therapy. * Participants with clinically significant ascites that require drainage. * A history of drug-induced non-infectious ILD/pneumonitis. * Central nervous system metastases or CNS pathology. * Peripheral neuropathy, sensory, or motor ≥ Grade 2 at screening. * History of another primary malignancy. * Prior exposure to any MMAE-based ADC. * Prior exposure to any CLDN18.2 targeted agents except anti-CLDN18.2 monoclonal antibody. Sub study 1 Specific Exclusion criteria: * Participants with HER2-positive (3+ by IHC, or 2+ by IHC, and positive by ISH) or indeterminate GC/GEJC unless they have failed/not tolerated/or are not eligible for standard anti-HER2 therapy, where available. * Any factors that increase the risk of QTc prolongation or risk of arrhythmic events. * The use of concomitant medications known to prolong the QT/QTc interval. Sub study 2 Specific Exclusion criteria: * Known DPD enzyme deficiency based on local testing where testing is SoC. * Use of strong inhibitor or inducer of UGT1A1. * Use of strong inhibitors or inducers of CYP3A4. * Known homozygous for the UGT1A1\*28 allele based on local testing where testing is SoC.
