You may qualify if…
- Patients diagnosed with prostate cancer and treated with androgen deprivation therapy (ADT) and at least one androgen receptor pathway inhibitor (ARPI) (eg, abiraterone, enzalutamide, apalutamide or darolutamide). Previous prostate-specific membrane antigen (PSMA)-targeted therapy or cytotoxic chemotherapy is allowed but not required.
- Androgen levels ≤50 ng/dL (≤1.73 nmol/L).
- Disease progression following ADT and ARPI treatment described
- PSA progression over 2 assessments, defined as rising PSA values from 2 consecutive assessments with an interval of at least 7 days between assessments. PSA levels prior to study enrollment are considered and appropriate for inclusion.
- Measurable disease by RECIST v1.1 on chest/abdomen/pelvis CT or evaluable disease observed on bone scan.
- Eastern Cooperative Oncology Group (ECOG) performance status 0, 1, or 2
- Appropriate hepatic function defined by a total bilirubin (TBL) ≤1.5 × the upper limit of normal (ULN), alanine aminotransferase (ALT) AND aspartate aminotransferase (AST) ≤3 × ULN at screening.
- Appropriate kidney function defined by calculated or actual creatinine clearance ≥30 mL/min
- Absolute neutrophil count (ANC) ≥ 1,500 cells/mm3.
- Platelets ≥100,000 cells/mm3.
- Serum hemoglobin level ≥8 g/dL.
- Agree to not donate blood or sperm during the study and for 90 days after the last dose of study treatment.
- Patients with sexual partners of childbearing potential must agree to use highly effective methods of contraception throughout the study
- Ability to understand and the willingness to sign a written informed consent document
You may not qualify if…
- Any investigational agent:
- within 4 weeks OR within a time interval less than at least 5 half-lives of the investigational agent, whichever is shorter, before initiating study treatment.
- Low PSA (≤10 ng/mL) at initial presentation (before ADT or at symptomatic progression in the castrate setting) plus high volume (≥20) bone metastases.
- Simultaneous enrollment in any other cancer treatment interventional clinical trial.
- Active, uncontrolled diarrhea leading to dehydration or electrolyte disturbances not controlled with oral repletion.
- Grade ≥3 uncontrolled infection.
- Major surgery (in the opinion of the treating investigator) ≤3 weeks before initiating study treatment.
- Not having fully recovered to a grade of 1 or lower from any surgery-related adverse effects within the 3 weeks preceding the start of the study treatment.
- Small cell, anaplastic, or neuroendocrine component.
- Known active brain metastasis.
- Known active leptomeningeal disease.
- Planned ongoing treatment with other drugs thought to potentially have adverse interactions with either of the medications included in the study treatment must be discontinued ≥2 weeks prior to initiating study treatment unless otherwise noted:
- Monoamine oxidase inhibitors (MAOI) use; must discontinue use 10 days prior to initiating study therapy.
- Strong or moderate CYP1A2, CYP3A4 and CYP2C19 inhibitors.
- Rucaparib, Olaparib and Talazoparib, due to their common findings of liver enzyme elevation.
- Inability to swallow medication.
- Known hypersensitivity to GZ17-6.02 components (curcumin, harmine, and isovanillin) or excipients.
- Known or suspected malabsorption condition or obstruction.
- Active untreated hepatitis B or C" and "Known liver cirrhosis of any cause, active nonalcoholic steatohepatitis, or nonalcoholic fatty liver disease. Note: no additional testing necessary to confirm
- Medical, psychological, or social condition that, in the opinion of the investigator, may increase the patient's risk or limit the patient's adherence with study requirements
