Study BT5528-100 in Patients With Advanced Solid Tumors Associated With EphA2 Expression

Phase I/II Study of the Safety, Pharmacokinetics, and Preliminary Clinical Activity of BT5528 in Patients With Advanced Malignancies Associated With EphA2 Expression

This clinical trial is evaluating a drug called BT5528 alone and in combination with nivolumab in participants with advanced solid tumors historically known for expression of EphA2. The main goals of this study are to:

• Find the recommended dose(s) of BT5528 that can be given safely to participants alone and in combination with nivolumab
• Learn more about the side effects of BT5528
• Learn about how effective BT5528 is for the treatment of ovarian cancer, urothelial/bladder cancer, lung cancer (NSCLC), triple-negative breast cancer, head and neck cancer (HNSCC), and gastric/upper gastrointestinal cancer.
• Learn more about BT5528 therapy alone and in combination with nivolumab.

Study Overview

• Status: Active, not recruiting
• Conditions: Head and Neck Cancer; Ovarian Cancer; Triple Negative Breast Cancer; Non-small Cell Lung Cancer; Advanced Solid Tumor Historically Known for High EphA2 Expression; Urothelial Cancer; Gastric/Upper Gastrointestinal Cancer
• Intervention / Treatment: Drug: BT5528; Drug: Nivolumab

Detailed Description

BT5528 consists of a bicyclic peptide (Bicycle®) which binds to EphA2, and is covalently attached to a spacer and a protease cleavable peptide linker attached to MMAE.

The Phase I/II multi-center, open-label trial will evaluate BT5528 administered once-weekly as a single agent and in combination with nivolumab. The Phase I portion is a dose escalation primarily designed to assess the safety and tolerability of BT5528 and to determine recommended Phase II dose(s) (RP2D). Following selection of a recommended Phase II dose(s) (RP2D), a dose expansion portion will be initiated with the primary objective of evaluating the clinical activity of BT5528.
