Popis: | TPS404 Background: There are currently no FDA approved modalities for intercepting biochemically recurrent prostate cancer (PCa) after standard of care surgery and radiation therapies to delay or prevent the need of androgen deprivation therapy (ADT) for localized disease. Preclinical modeling has suggested herbal alcoholic extracts of Angelica gigas Nakai (AGN) root, their signature pyranocoumarins and metabolite decursinol, as potential novel modalities to address this unmet clinical need. We hypothesize that CognI.Q at the higher doses has an acceptable safety profile in prostate cancer patients and pharmacokinetics (PK) exposure metrics will be increased proportional to dose increment. Methods: This is a single institution, phase 1 PK study, N=12. Primary objective- PK, pharmacodynamic (PD) biomarkers with a single ascending dose (SAD)-PK response design. After a subject is enrolled, a 14-day gap must occur before the next subject can be enrolled. If one subject develops a dose limiting toxicity (DLT) at any dose level, that subject will stop participation; If a 2nd subject develops DLT at the same dose level, the trial will be stopped, and the dose level below will be the maximum tolerated dose (MTD). Any subject at a higher dose level at the time of occurrence of 2nd DLT will also stop participation. All subjects will initially start at the 800 mg x 1dose, with further single dose escalation to 1200mg, 1600mg, 2000mg doses of AGN-CognI.Q; each dose will be 1-2 weeks apart. Inclusion criteria: Treated PCa, not on ADT; no active cancer. Subjects will be assessed for safety- clinical, labs (CBC, CMP, baseline and after 24hrs) and EKGs. PK blood will be taken at hourly intervals from 2-7hrs and 24hrs. Plasma pyranocoumarin content will be measured by LC-MS. Immunophenotyping of NK and T cell subtypes will be assessed at baseline and 24 h. Primary Endpoint: MTD. Secondary Endpoint: PK metrics; genotype CYP 2C19 and 3A4 metabolizer status and explore relationship to PK metrics and safety metrics; NK and inflammatory and immune cytokines as PD biomarkers. Trial is now open to accrual (Clinical trial registration NCT05375539). We anticipate that the acute dose safety and PK/PD information will inform the optimal design and execution of the longer-term safety and efficacy (phase I/II) trials.
