ArtemiCoffee in Patients With Rising PSA

This is an open-labeled phase II study of Artemisia annua (Aa) decaf coffee in patients with biochemical recurrence of prostate cancer.

Inclusion criteria

• Completion of localized therapy (prostatectomy or radiotherapy) for prostate adenocarcinoma (either histologically or cytologically confirmed)
• Biochemical PSA recurrence
• Age ≥18 years.
• Eastern Cooperative Oncology Group (ECOG) performance status ≤3
• Total bilirubin ≤ 1.5 x upper normal limit (ULN), and AST (aspartate transaminase) and ALT (alanine transaminase) ≤ 3.0 x ULN
• Patients with a prior or concurrent malignancy (non-prostate) whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen as determined by the treating physician are eligible.
• Ability to understand and the willingness to sign a written informed consent document.

Exclusion criteria

• Any radiological evidence of metastatic disease (determined by standard of care computed tomography (CT) scans of abdomen, pelvis, chest, whole body bone scan or Axium PET/CT scan or prostate specific membrane antigen (PSMA) PET/CT scan).
• Receipt of prior cytotoxic chemotherapy for recurrent prostate cancer
• Use of androgen deprivation therapy (for example, bicalutamide, flutamide, nilutamide, or leuprolide acetate) concurrently or within the previous 3 months.
• Uncontrolled intercurrent illness such as active infections. Other illnesses will be evaluated and eligibility status determined at the discretion of the treating physician and the investigator.
• Psychiatric illness/social situations that would limit compliance with study requirements.
• Concomitant use of nevirapine, ritonavir, and strong UGT inducers or strong UGT inhibitors such as phenobarbital, rifampin, carbamazepine, diclofenac, imatinib, axitinib, and vandetanib
• Concurrent use of strong inducers of CYP2A6, including phenobarbital and rifampin
