NUV-868-01

Details and patient eligibility

About

NUV-868-01 is a first-in human, open- label, Phase 1/2 dose escalation and expansion study in patients with advanced solid tumors. The Phase 1 and 1b portions include patients with advanced solid tumors and are designed to determine the safety and the dose(s) of NUV-868 to be used as monotherapy and in combination with olaparib or enzalutamide for the Phase 2 portion. In Phase 2, NUV-868 in combination with olaparib or enzalutamide will be given to determine the safety and efficacy of these study treatments. One cohort of patients (with enzalutamide-naïve metastatic castration-resistant prostate cancer) will be randomized to receive either NUV-868 monotherapy, enzalutamide monotherapy, or the combination of NUV-868 + enzalutamide. Patients will self-administer NUV-868 orally daily in 28-day cycles as monotherapy in Phases 1 and 2. In Phases 1b and 2, patients will self-administer NUV-868 orally daily in 28-day cycles in combination with olaparib or enzalutamide daily at standard prescribed doses (Phase 1b) or at the recommended Phase 2 combination dose (RP2cD) that is determined in Phase 1b. Patients will be treated until disease progression, toxicity, withdrawal of consent, or termination of the study.

3. (Select cohorts only) Measurable disease

4. Patient must be able to read and write sufficiently to document food intake and study drug dosing on the Dosing Diary or must have a caregiver who is willing and able to complete the Dosing Diary with the patient.

5. One of the following tumor types:

   1. Ovarian: Platinum-resistant OR platinum-refractory high grade serous ovarian, fallopian, or primary peritoneal cancer in the relapsed setting
   2. Pancreatic: Pancreatic ductal adenocarcinoma (PDAC) with progression on or after treatment with at least one line of systemic chemotherapy in the advanced setting
   3. Prostate: Histologically confirmed, metastatic adenocarcinoma of the prostate (adenocarcinoma/high grade carcinoma with neuroendocrine features is allowed) with progression on or after treatment with at least one NHT in the metastatic setting
   4. Breast: Triple-negative breast cancer (TNBC) with progression on or after treatment with at least one line of systemic chemotherapy in the advanced setting
   5. Other advanced tumors (only Phase 1b dose escalation, NUV-868 + olaparib): the study Medical Monitor must approve enrollment.
   6. For all tumor types: Patients will be allowed in the study regardless of their BRCA/HRR status.

Phase 2
