Official Title ICMJE | Phase I/IIa, First-in-human, Open-label, Dose Escalation Trial With Expansion Cohorts to Evaluate Safety, Pharmacokinetics, Pharmacodynamics, and Preliminary Efficacy of BNT141 as a Monotherapy and in Combination With Other Anti-cancer Agents in Patients With CLDN18.2-positive Solid Tumors | ||||||
Brief Summary | This trial is an open-label, multi-site, Phase I/IIa dose escalation, safety, and pharmacokinetic (PK) trial of BNT141 followed by expansion cohorts in patients with CLDN18.2-positive tumors. The trial design consists of three parts: Part 1A is a dose escalation of BNT141 as monotherapy in patients with advanced unresectable or metastatic Claudin 18.2 (CLDN18.2)-positive solid tumors for which there is no available standard therapy likely to confer clinical benefit, or the patient is not a candidate for such available therapy. The dose of BNT141 will be escalated until the maximum tolerated dose (MTD) and/or recommended phase II dose (RP2D) of BNT141 as monotherapy are defined. Eligible tumor types are gastric cancer, gastroesophageal junction (GEJ) and esophageal adenocarcinoma, pancreatic, biliary tract (cholangiocarcinoma and gallbladder cancer), and mucinous ovarian cancers. Additionally, patients with specific tumors (including colorectal cancer, non-small-cell lung cancer, gastric subtype of endocervical adenocarcinoma) where there is scientific evidence that the CLDN18.2 could be elevated can be tested for CLDN18.2 expression. Part 1B is a dose escalation of BNT141 in combination with nab-paclitaxel and gemcitabine in patients with advanced unresectable or metastatic CLDN18.2-positive pancreatic adenocarcinoma or cholangiocarcinoma who are eligible for treatment with nab-paclitaxel and gemcitabine. Part 1B intends to define the MTD and/or RP2D of the combination. Part 2 with adaptive design elements will be added at a later stage. |

Eligibility Criteria ICMJE | Key inclusion criteria: For all Parts:
Trial part-specific inclusion criteria: For Part 1A: Patients with solid tumors, for which there is no available standard therapy likely to confer clinical benefit, or the patient is not a candidate for such available therapy. Patients must have received all available standard therapies and failed at least first-line standard of care (SOC) therapy prior to enrolment. Measurable or evaluable disease per RECIST 1.1. Eligible tumor types are gastric cancer, gastroesophageal junction (GEJ) and esophageal adenocarcinoma, pancreatic, biliary tract (cholangiocarcinoma and gallbladder cancer), and mucinous ovarian cancers. Additionally, patients with specific tumors (including colorectal cancer, non-small-cell lung cancer, gastric subtype of endocervical adenocarcinoma) where there is scientific evidence that the CLDN18.2 could be elevated can be tested for CLDN18.2 expression. For Part 1B: Patients with advanced pancreatic adenocarcinoma or cholangiocarcinoma who are eligible for treatment with nab-paclitaxel and gemcitabine. Measurable or evaluable disease per RECIST 1.1.
