AGN-Cogni.Q Acute Dose Safety and Pharmacokinetics Dose-Response in Prostate Cancer Patients

The long-term goal of the study is to conduct human clinical trials to test Angelica gigas Nakai (AGN) root alcoholic extract herbal supplement product (AGN-Cogni.Q, or Cogni.QTM, made with INM®176 proprietary ingredient, Quality of Life Laboratories, Purchase, NY) as a safe and potential efficacious modality for prostate cancer interception akin to secondary prevention to delay hormonal therapy or avoid it entirely after patients have developed recurrent disease following their standard of care (SOC) surgery and radiation curative treatment. The acute dose safety and pharmacokinetics (PK) and pharmacodynamics (PD) information in the target patient population from the current proposed acute PK dose-response trial will inform the optimal design and execution of the longer-term safety and efficacy (phase I/II) trials.
