Brief 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 expressing 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.

Condition or disease Intervention/treatment Phase
Locally Advanced/Metastatic HER2 Positive Solid Tumors Drug: BB-1701 Phase 1

Detailed Description:

This is an open-label, FIH, phase 1 dose-escalation and cohort expansion study of BB-1701 in subjects with locally advanced /metastatic HER2 expressing 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 expressing locally advanced/metastatic solid tumors.

Part 2 consists of 4 cohorts:

Cohort 1: Patients with HER2 overexpressing or positive (defined as IHC 3+ or IHC 2+/FISH positive) locally advanced or metastatic breast cancer who have progressed on prior standard therapies including anti HER2 therapy

Cohort 2: Patients with HER2 low expressing (defined as IHC 2+ /FISH negative, or IHC 1+) locally advanced or metastatic breast cancer who have progressed on prior standard therapies.

Cohort 3: Patients with HER2 overexpressing or positive (defined as IHC 3+ or IHC 2+/FISH positive) locally advanced or metastatic gastric cancer or gastroesophageal junction cancer who have progressed on prior standard therapies.

Cohort 4: Patients with HER2 overexpressing or positive (defined as IHC 3+, or IHC 2+/FISH positive) locally advanced or metastatic solid tumors (other than breast cancer and gastric or gastroesophageal junction cancer) who have progressed on prior standard therapies. Patients with HER2 mutation or amplification by NGS can also be enrolled in this cohort.

Secondary Outcome Measures :
  1. Area under the serum concentration time curve from time 0 extrapolated to infinity (AUC0-inf) [ Time Frame: Cycle 1 Day 1. Duration of each cycle is 21 days. ]
    To characterize the pharmacokinetics (PK) of BB-1701

  2. Maximum observed plasma concentration (Cmax) [ Time Frame: Pre-dose and post-dose during Cycle 1 through Cycle 8. Duration of each cycle is 21 days. ]
    To characterize the PK of BB-1701

  3. Incidence of anti-drug antibodies [ Time Frame: Cycle 1 Day 1, Cycle 1 Day 15, and Day 1 of Cycles 2, 3, 4, 6, and 8. Duration of each cycle is 21 days. ]
    To assess the immunogenicity of BB-1701

  4. Objective response [ Time Frame: Every 9 weeks within 6 months and approximately every 12 weeks thereafter (up to 2 years) ]
    To assess the preliminary anti-tumor activity of BB-1701

  5. Progression Free Survival [ Time Frame: Every 9 weeks within 6 months and approximately every 12 weeks thereafter (up to 2 years) ]
    To assess the preliminary anti-tumor activity of BB-1701

  6. Duration of Response [ Time Frame: Every 9 weeks within 6 months and approximately every 12 weeks thereafter (up to 2 years) ]
    To assess the preliminary anti-tumor activity of BB-1701
