Study Details

Study Description

Brief Summary

Open label, nonrandomized, dose-escalation with cohort expansion trial of MVT-5873/MVT-1075 in subjects with previously treated, CA19-9 positive malignancies (e.g., pancreatic adenocarcinoma).

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

Open label, nonrandomized, dose escalation trial of MVT-5873/MVT-1075 to evaluate safety, dosimetry, determine the MTD and recommended phase 2 dose, and define the pharmacokinetics of MVT-1075. The population consists of subjects with CA19-9 positive malignancies (i.e., predominately pancreatic adenocarcinoma) who may benefit from a CA19-9-based radioimmunotherapy.

The study will utilize a 3+3 study design to identify the MTD. The RP2D will be no higher than the MTD. An expansion group will receive MVT-5873/MVT-1075 at the RP2D in order to obtain initial estimates of response and additional information on safety.
