RC48-G001
A Phase 2 Multi Cohort, Open Label, Multi-Center Clinical Study Evaluating the Efficacy and Safety of Disitamab Vedotin (RC48-ADC) Alone and in Combination with Pembrolizumab in Subjects with Locally Advanced Unresectable or Metastatic Urothelial Carcinoma That Expresses HER2
Trial overview
Topic
Urothelial cancer
Study details
This study is being done to see if a drug called disitamab vedotin, alone or with pembrolizumab, works to treat HER2 expressing urothelial cancer. It will also test how safe the drug is for participants.
Participants will have cancer that has spread in the body near where it started (locally advanced) and cannot be removed (unresectable) or has spread through the body (metastatic).
It will also study what side effects happen when participants get the drug. A side effect is anything a drug does to your body besides treating the disease.
Eligibility criteria
Inclusion Criteria:
- Histologically-confirmed, locally-advanced, unresectable or metastatic urothelial cancer (LA/mUC), including UC originating from the renal pelvis, ureters, bladder, or urethra
- Cohorts A and B: Participants must have received only 1 or 2 lines of prior systemic treatment for LA/mUC, including 1 line of platinum-containing chemotherapy
- Cohort C: No prior systemic therapy for LA/mUC
- Cohorts A and B only: Radiographically documented disease progression during or after the most recent line of therapy for LA/mUC
- Cohort C only: Participant is eligible to receive cisplatin- or carboplatin- containing chemotherapy per investigator evaluation
- HER2-expression status determined by the central laboratory to be IHC 1+, 2+ or 3+, in the provided tumor sample
Exclusion Criteria:
- Prior antitumor treatment (including chemotherapy, radiotherapy, targeted therapy, immunotherapy etc.) within 2 weeks of start of study
- Toxicity from a previous treatment has not returned to Grades 0 or 1 (except for Grade 2 alopecia)
- Prior MMAE-based ADCs (eg, enfortumab vedotin) or HER2-directed therapy
- Peripheral sensory or motor neuropathy ≥ Grade 2 at baseline
There are additional inclusion and exclusion criteria. The study centre will determine if criteria for participation are met.
