Brief summary
NUV-422-04 is an open-label Phase 1b/2 dose escalation and expansion study designed to evaluate the safety and efficacy of NUV-422 in combination with enzalutamide. The study population is comprised of adults with mCRPC. Patients will self-administer NUV-422 and 160 mg enzalutamide orally in 28-day cycles. Patients will be treated until disease progression, toxicity, withdrawal of consent, or termination of the study.
Interventions
NUV-422 is an investigational drug for oral dosing.

Requires medications that are known to be strong inducers and /or inhibitors of CYP3A4/5 enzymes, except enzalutamide * For Phase 1b only: Requires medications that are known to be moderate inducers and /or inhibitors of CYP3A4/5 enzymes, except enzalutamide 5. Prior therapy with enzalutamide, apalutamide, darolutamide, or investigational androgen receptor inhibitors 6. Known allergy or hypersensitivity to enzalutamide
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Phase 1b Dose Escalation: Safety and tolerability of NUV-422 in combination with enzalutamide to determine the recommended Phase 2 combination dose (RP2cD) | During the DLT period (28 days) | Incidence of treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), dose-limiting toxicities (DLTs), and laboratory abnormalities |
| Phase 2 Dose Expansion: Prostate-specific antigen (PSA)-response rate (PSA-RR) | Every 4 weeks throughout study treatment, an average of 6 months | PSA per standard criteria |
| Phase 2 Dose Expansion: Objective response rate (ORR) | Every 8 weeks throughout study treatment, an average of 6 months | ORR per standard criteria |
