Brief Summary:

This is a study of trastuzumab deruxtecan, which was approved by the FDA (in December 2019) for the treatment of HER2-positive unresectable or metastatic breast cancer following two or more prior anti-HER2 based regimens.

Participants will receive this study drug along with a cancer drug, an immune checkpoint inhibitor, anti-PD1, called nivolumab.

The study will be done in two parts:

  • Part 1 is to identify the recommended dose to use for treatment.
  • Part 2 is to find out how well the combination works, and how safe and tolerable it is.

Condition or disease Intervention/treatment Phase
Breast Cancer Urothelial Carcinoma Drug: Trastuzumab deruxtecan Drug: Nivolumab Phase 1

Detailed Description:

The purpose of this phase 1b (Part 1, Part 2) study is to assess the combination of a test drug (trastuzumab deruxtecan) with nivolumab in participants with HER2-expressing breast and urothelial cancer who had disease progression during or after prior therapies, did not respond to standard therapies, or for whom no standard therapy is available.

The study will be performed in 2 parts.

  • Part 1 is to test different doses of trastuzumab deruxtecan when given along with a fixed dose of nivolumab, and establish the most effective and the maximum/recommended tolerated dose, when used in combination with nivolumab
  • Part 2 is to assess the efficacy and safety of this dose combination.

Arm Intervention/treatment
Experimental: Dose Escalation

Part 1 will enroll participants meeting the eligibility criteria set up for any of the 4 cohorts of Part 2 specified below using a 3 + 3 + 3 design. Escalating/de-escalating doses of trastuzumab deruxtecan in combination with a flat dose of nivolumab will be administered on Day 1 of each 21-day cycle.

The recommended dose for expansion (RDE) will be calculated using data collected from this population in the first two cycles. These participants may continue to receive study treatment in subsequent cycles.

Primary Outcome Measures :
  1. Part 1: Number of participants with dose-limiting toxicity at each dose level [ Time Frame: 2 cycles (within 2 months) ]
    Categories: Low Dose, High Dose

  2. Part 2: Dose expansion - Objective response rate (ORR) as assessed by Central Imaging Review [ Time Frame: 6 months after the last participant is enrolled, or when 80% of participants have experienced disease progression or discontinued study treatment, whichever occurs first (within 24 months) ]
    ORR is defined as the percentage of participants with tumor size reduction of a predefined amount and for a minimum time period. ORR includes partial response (PR) and complete response (CR). ORR will be assessed by Central Imaging Review based on Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.

  3. Number of participants with treatment emergent adverse events (TEAEs) during the trial [ Time Frame: at the time of final database lock (anticipated within three years) ]
    Total number of participants in the safety analysis set with TEAEs collected during the trial (including follow-up periods), for inclusion in the database


Secondary Outcome Measures :
  1. Duration of Response (DoR) [ Time Frame: within 24 months ]
  2. Disease Control Rate (DCR) [ Time Frame: within 24 months ]
  3. Progression Free Survival (PFS) [ Time Frame: within 24 months ]
    PFS is defined as the time from randomization until objective tumor progression or death, whichever occurs first.

  4. Time to Response based on central review [ Time Frame: within 24 months ]
  5. Overall Survival (OS) [ Time Frame: within 24 months ]
    Overall survival is defined as the time from randomization until death from any cause and is measured in the intent-to-treat population.

  6. ORR [ Time Frame: within 24 months ]
    ORR, as assessed by the investigator based on RECIST Version 1.1.
