Clinical Trials Identifier NCT 8-digits: NCT07484022

Sponsor: Generate Biomedicines

Phase: Phase 1

Eligibility:

• Age: minimum 18 Years maximum N/A
• Gender: All

Inclusion Criteria:

• Planned to receive standard-of-care treatment with enfortumab vedotin (EV) (starting dose 1.25 mg/kg) in combination with pembrolizumab for locally advanced or metastatic urothelial cancer.
• Age ≥18 years.
• ECOG Performance Status score of 0 or 1 (ECOG 2 excluded in Dose Escalation but allowed in Dose Expansion).
• Weight ≥50 kg at screening.
• Life expectancy ≥3 months, as determined by the investigator.
• Participants must provide written informed consent before any study-related activities are carried out and must be able to understand the nature and purpose of the study, including potential risks and adverse effects.
• Willing and able to comply with all study assessments and adhere to the protocol schedule and restrictions.

Exclusion Criteria:

• Previously received enfortumab vedotin (EV) or other MMAE-based antibody-drug conjugates (ADCs).
• Received anti-cancer treatment with chemotherapy, biologics, or investigational agents within 4 weeks before the first dose of EV/pembrolizumab.
• Uncontrolled diabetes.
• Active CNS metastases. Participants with treated CNS metastases are permitted if all of the following criteria are met:
• CNS metastases have been clinically stable for at least 4 weeks prior to screening and baseline scans show no evidence of new or enlarged metastasis.
• The participant is on a stable dose of ≤10 mg/day of prednisone or equivalent for at least 2 weeks (if requiring steroid treatment).
• The participant does not have leptomeningeal disease.
• Ongoing clinically significant toxicity associated with prior treatment (including radiotherapy or surgery) that has not resolved to Grade ≤1 or returned to baseline.
• History of a severe (Grade ≥3) allergic or infusion-related reaction to any monoclonal antibody.
• Another underlying medical condition that, in the opinion of the investigator, would impair the ability of the participant to receive or tolerate the planned treatment and follow-up.
