What You Need to Know Before You Apply

What is the purpose of this trial?

This is a Phase 1b dose escalation trial of OMTX705, an anti-fibroblast activation protein (FAP) antibody-drug conjugate (ADC), in combination with gemcitabine/nab-paclitaxel and tislelizumab in patients with advanced/metastatic pancreatic ductal adenocarcinoma (PDAC).

The trial will be conducted in two parts (Part 1 and Part 2). Both parts will enroll participants with advanced PDAC that, in general, are eligible to receive gemcitabine/nab-paclitaxel. Part 1 is intended to determine the safe recommended dose of OMTX705 in combination with gemcitabine/nab-paclitaxel (1A) and in combination with gemcitabine/nab-paclitaxel+tislelizumab (1B). Both 1A and 1B will enroll in a standard 3+3 design. Only one dose level of OMTX705 will be selected for Part 2 by a Data Safety Monitoring Board (DSMB). In Part 2, 3 parallel randomized arms will be opened simultaneously with 1:1:1 randomization (N=15 each): OMTX705+gemcitabine/nab-paclitaxel (arm 2A), OMTX705+tislelizumab+gemcitabine/nab-paclitaxel (arm 2B) and gemcitabine/nab-paclitaxel (arm 2C, reference arm).

Are You a Good Fit for This Trial?

This trial is for adults with advanced or metastatic pancreatic cancer who can consent, have measurable disease, good performance status (able to carry out daily activities), and proper organ function. They must not have had more than one prior chemotherapy line and agree to use effective contraception.

What Are the Treatments Tested in This Trial?

Interventions

  • Nab-paclitaxel + Gemcitabine
  • OMTX705
  • Tislelizumab

Trial Overview

The study tests OMTX705 combined with gemcitabine/nab-paclitaxel and tislelizumab in two parts: finding a safe dose (Part 1) and comparing three treatment arms in randomized groups (Part 2). The goal is to see how well these combinations work for pancreatic cancer.
