Recruiting PHASE1 Advanced Urothelial Cancer

New treatment option for Advanced Urothelial Cancer

Official title Study of GB-4362 With Enfortumab Vedotin and Pembrolizumab for Advanced Urothelial Cancer

ClinicalTrials.gov ID: NCT07484022

What this study is testing

What is GB-4362?

GB-4362 is an investigational medicine, being studied as a potential treatment for advanced urothelial cancer.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The purpose of this study is to evaluate the safety and tolerability of an investigational drug called GB-4362 when it is given together with enfortumab vedotin and pembrolizumab in adults with advanced or metastatic urothelial cancer. GB-4362 is a monoclonal antibody designed to bind and neutralize free monomethyl auristatin E (MMAE), a chemotherapy payload released from enfortumab vedotin that is associated with side effects such as peripheral neuropathy.

Who can take part

Ages 18 and older

You may be able to join if

  • Planned to receive standard-of-care treatment with enfortumab vedotin (EV) (starting dose 1.25 mg/kg) in combination with pembrolizumab for locally...
  • 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.

You likely can't join if

  • 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).
