Brief Summary:

This is an open-label, multi-center, multi-cohort, Phase 2 study to evaluate the efficacy and safety of trastuzumab deruxtecan (T-DXd) for the treatment of selected HER2-expressing tumors.

This study will enroll 7 cohorts: urothelial bladder cancer, biliary tract cancer, cervical cancer, endometrial cancer, ovarian cancer, pancreatic cancer, and rare tumors.

Study hypothesis: Trastuzumab deruxtecan will show meaningful clinical activity and a favorable risk benefit profile in selected HER2-expressing solid tumors.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: An average of approximately 41 months ]
    Confirmed ORR per RECIST 1.1 is the percentage of patients with Complete Response or Partial Response that is subsequently confirmed.


Secondary Outcome Measures :
  1. Duration of response (DoR) [ Time Frame: An average of approximately 41 months ]
    DOR is defined as the time from the date of first documented response until the date of documented progression or death.

  2. Disease control rate (DCR) [ Time Frame: An average of approximately 41 months ]
    DCR is the percentage of subjects who have a best overall response of complete response (CR) or partial response (PR) or stable disease (SD).

  3. Progression free survival (PFS) [ Time Frame: An average of approximately 41 months ]
    PFS is the time from date of first dose of study treatment until the date of objective disease progression or death.

  4. Proportion of patients alive and progression-free at 6 months and 12 months [ Time Frame: Up to 12 months ]
    The proportion of patients alive and progression-free at 6 and 12 months (Kaplan-Meier estimates).

  5. Overall survival (OS) [ Time Frame: An average of approximately 41 months ]
    OS is the time from date of first dose of study treatment until death due to any cause.

  6. Proportion of patients alive at 6 and 12 months [ Time Frame: Up to 12 months ]
    The proportion of patients alive at 6 and 12 months (Kaplan-Meier estimates).

  7. Occurrence of adverse events (AEs) and serious adverse events (SAEs) [ Time Frame: An average of approximately 41 months ]
    Occurrence of AEs and SAEs graded according to NCI CTCAE v5.0.

  8. Pharmacokinetics (PK) assessed by serum concentration of T-DXd, total anti-HER2 antibody and MAAA-1181 [ Time Frame: An average of approximately 41 months ]
    Individual patient data and descriptive statistics will be provided for serum concentration data at each time point for T-DXd, total anti-HER2 antibody and MAAA-1181a

  9. The immunogenicity of T-DXd assessed by the presence of ADAs for T-DXd [ Time Frame: An average of approximately 41 months ]
    Individual participant data and descriptive statistics will be provided for data at each time point.
