EU CTIS ID: 2023-509781-37-00
What this study is testing
Primary obj. for escalation (A-1 & A-2) and renal insufficiency (C) and supplementary PK (D) cohorts: - Assess safety and tolerability of zelenectide pevedotin in pts with advanced solid tumor malignancies associated with Nectin-4 expression: a) as monotherapy (A- 1); b) in combination with pembrolizumab (A-2); c) moderate to severe renal insufficiency (C). - Define MTD and determine RP2D(s) (A-1&A-2). - To further characterize the PK of zelenectide pevedotin (BT8009) and MMAE (D). Primary obj. for expansion (B): - Assess the ORR of zelenectide pevedotin (BT8009) as a monotherapy in pts with EV-exposed (B-1) or EV-naïve (B-2&B-3) urothelial carcinoma using RECIST V1.1 (metastatic urothelial cancer pts). - Assess ORR of zelenectide pevedotin (BT8009) as a monotherapy in pts with solid tumor with Nectin-4 expression B-4 [ovarian], B5 [TNBC], and B-6 [NSCLC]) using RECIST V1.1. - Assess ORR of zelenectide pevedotin (BT8009) in cisplatin-ineligible pts with locally advanced or metastatic urothelial carcinoma in combination with pembrolizumab using RECIST 1.1 (B-7). - Further characterize the PK of zelenectide pevedotin (BT8009) and MMAE(D). - Assess the safety and tolerability of the alternative dosing regimen of zelenectide pevedotin (BT8009) monotherapy of 6mg/m^2 day 1 and 8 of a 21 day cycle (B-8 and B-9).

Significant medical condition including but not limited to skin (conditions related to or that may confound monitoring for rash including but not limited to autoimmune conditions such as eczema or psoriasis), life-threatening illness, active uncontrolled infection or organ system dysfunction (such as ascites, coagulopathy, encephalopathy), or other reasons which, in the Investigator opinion, could compromise the patient’s safety, or interfere with or compromise the integrity of the study outcomes, including consideration of gastrointestinal, skin and pulmonary co-morbidities and including review of screening chest CT to ensure no clinically significant co-morbidities. Treatment induced ≤ Grade 2 endocrinopathy is allowed, if appropriately controlled with supplemental hormone replacement and stable for at least 2 months on therapy. Skin toxicity should resolve to Grade ≤1.
