Description

Summary

This is an open-label, first-in-human (FIH), phase 1 dose-escalation and cohort expansion study of BB-1701 in subjects with locally advanced/metastatic HER2 positive solid tumors. The study consists of 2 parts: dose-escalation (Part 1) and cohort expansion (Part 2). Part 1 consists of dose escalation cohorts for determining the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D). Part 2 consists of expansion cohorts, including but not limited to breast cancer, gastric/gastroesophageal junction cancer, bladder cancer and colon cancer, for exploring 1 or more RP2Ds or schedules for expanding/deepening the information/knowledge about clinical safety, clinical pharmacokinetics and anti-tumor activity.

Official Title

A First-in-human, Open Label, Multiple Dose, Dose Escalation and Cohort Expansion Phase I Study to Investigate the Safety, Tolerability, Pharmacokinetics and Antitumor Activities of BB-1701 in Subjects With Locally Advanced/Metastatic HER2 Positive Solid Tumors

Details

This is an open-label, FIH, phase 1 dose-escalation and cohort expansion study of BB-1701 in subjects with locally advanced /metastatic HER2 positive solid tumors. The study consists of 2 parts: dose-escalation (Part 1) and cohort expansion (Part 2).

Part 1 of this study will follow accelerated titration and traditional "3 + 3" design. Part 2 is a cohort expansion study with HER2 positive locally advanced/metastatic solid tumors. Part 2 consists of 2 cohorts: Cohort 1 includes subjects with HER2 positive breast cancer, who must have received prior 3 lines of HER2 targeting therapies and Cohort 2 includes subjects with HER2 positive cancers including but not limited to gastric/gastroesophageal junction cancer (GC/GEJ), bladder cancer and colon cancer; prior HER2 therapy not required for cancer types other than GC/GEJ.

Study duration consists of Screening (up to 28 days), Treatment cycles (up to 8 cycles), and Safety Follow-up (30 days).
