About this trial
This is an interventional treatment trial for Prostate Cancer
Eligibility Criteria
Inclusion Criteria:
- confirmed adenocarcinoma of the prostate
- undergone definitive treatment (surgery, surgery with radiation therapy, cryotherapy, radiation therapy or brachytherapy) for the primary prostate tumor with a rising PSA
- life expectancy greater than 6 months
- has Eastern Cooperative Oncology Group (ECOG) performance status 0, 1, or 2
- use of other dietary/herbal supplements (e.g. saw palmetto, selenium, etc.) has been stable for at least 2 months prior to screening and the patient agrees not to stop or change the dose while participating in the study.
- Adequate hepatic function with serum bilirubin ≤ 1.5 times the upper institutional limits of normal, ALT and AST ≤ 2.5 times the upper institutional limits of normal
- Adequate renal function with serum creatinine ≤ 1.5 times the upper institutional limits of normal
- Adequate hematologic function (absolute neutrophil counts ≥ 1,500 mm3 and platelets ≥ 100,000 mm3)
- All electrolytes (including potassium, sodium, and serum or ionized calcium) must be within normal limits
Exclusion Criteria:
- Patients with evidence of metastatic disease would be excluded, except for presence of positive lymph nodes from the surgical pathology. Similarly, patients with radiological evidence of lymph nodes < 2 cm that lack pathological confirmation would be eligible
- Patients with a PSA doubling time of <6months at screening would be excluded
- Patients meeting Phoenix criteria for biochemical failure (nadir + ≥2ng/mL increase in serum PSA) who wish additional conventional therapy
- Any concurrent malignancy other than adequately treated basal or squamous cell skin cancer or superficial bladder cancer
- Any psychiatric or other disorders such as dementia that would prohibit the patient from understanding or rendering informed consent or from fully complying with protocol treatment and follow-up
- Inability to swallow capsules
- Patients with a known history of gastrointestinal disease, surgery or malabsorption that could potentially impact the absorption of the study drug
- Patients requiring the use of a feeding tube
- Receipt of prior chemotherapy

Arms of the Study
Arm 1
Arm 2
Arm Type
Experimental
Experimental
Arm Label
KLTc high dose
KLTc low dose
Arm Description
6 KLTc gelcaps taken four times a day
3 KLTc gelcaps taken four times a day
Outcomes
Primary Outcome Measures
prostate specific antigen doubling time (PSADT)
PSADT is defined as the natural log of 2 (0.693)divided by the slope (beta- rate of change) of the relationship between the log of PSA and the time of PSA measurement using linear regression model
Secondary Outcome Measures
PSA objective response
a 50% or more decline in PSA level compared to baseline
KLTc intake compliance
actual number of capsules taken divided by the expected number of capsules taken multiplied by 100 to get a percentage of compliance
