MCS in Treating Lower Urinary Tract Symptoms (LUTS) Suggestive of Benign Prostatic Hyperplasia
Double-Blind, Randomized, Placebo-Controlled Study to Investigate the Efficacy and Safety of MCS in Treating Lower Urinary Tract Symptoms Suggestive of Benign Prostatic Hyperplasia
Phase III, Randomized, double-blind, parallel placebo-controlled study. Two arms: MCS (30mg/day) vs. placebo.
Subproject MCS-2: alpha-blocker naïve subjects
Subproject MCS-3: subjects responding poorly to alpha-blocker

Detailed Description
For MCS-2 This is a double-blind, randomized, placebo-controlled, parallel study where eligible male subjects (age 40, N=188), after a two-week washout period, will be randomized at 1:1 ratio to receive either MCS 30 mg/day or placebo for 12 weeks.
Group A: MCS 30 mg/day for 12 weeks Group B: placebo for 12 weeks
Subjects are limited to those who are currently not being treated medically for BPH or LUTS with alpha-blockers, anti-cholinergics, 5-alpha reductase inhibitors, or hormonal therapeutic agents. For each treatment arm, about 85 subjects eligible for final per protocol analysis will be recruited. Concerning an expected dropout rate of 10%, 188 subjects in total will be recruited onto the study.
For MCS-3 This is a double-blind, randomized, placebo-controlled, add-on, parallel study where eligible male subjects (age 40, N=242), after a two-week washout period, will be randomized at 1:1 ratio to receive either MCS 30 mg/day plus alpha-blocker or placebo plus alpha-blocker for 12 weeks.
Group A: alpha-blocker plus MCS 30 mg/day Group B: alpha-blocker plus placebo
Subjects are limited to those who are currently not being treated medically for BPH or LUTS with anti-cholinergics, 5-alpha reductase inhibitors, or hormonal therapeutic agents. For each treatment arm, about 220 subjects eligible for final per protocol analysis will be recruited. Concerning an expected dropout rate of 10%, 242 subjects in total will be recruited onto the study.
All participating subjects will be advised to maintain a normal diet as they do before joining the study. However, participating subjects are advised to refrain from extra source of carotenoids supplementation and MCS extracts made into a capsule, soft gel, or crude granule extracts.

Description
Inclusion criteria for subproject MCS-2
- Age ≧ 40 years old.
- Not being treated for BPH or LUTS with Alpha-blocker, anti-cholinergics, 5-alpha reductase inhibitors, or hormonal agents.
- PSA≦4 ng/ml within 4 weeks of V1 and no pathologically-proven prostate cancer.
- No known malignancy, except cancers without signs of recurrence for > 5 years and no need for further anti-cancer treatment.
- AST/ALT≦3X UNL.
- creatinine≦3X UNL.
- Subjects who sign the informed consent form.
Exclusion criteria
- Subjects' LUTS are not BPH-related but are associated with such conditions as urethral stricture, prostatitis, neurogenic bladder, or pelvic treatment procedures.
- Have been treated with pelvis irradiation or pelvic surgery.
- Plan to undergo any invasive procedures within the study period, such as, prostate surgery, prostate biopsy, cystourethroscopy, pelvic surgery, laparotomy, or any procedures needing urethral catheterization.
- Participating in another investigational agent study in the past 12 weeks or are going to do so during the study period.
- Active infection or inflammation.
- Considered ineligible by the investigators.
Inclusion criteria for subproject MCS-3
- Age≧40 years old.
- The alpha-blocker dosage used should be as high as subjects can tolerate.
- No known malignancy, except cancers without signs of recurrence for > 5 years and no need for further anti-cancer treatment.
- PSA≦10.0 ng/ml without pathologically-proven prostate cancer or other cancers. Prostate biopsy is mandatory > 12 weeks before screening, if PSA is≧4 ng/ml to rule out prostate cancer.
- AST/ALT≦3X UNL.
- Creatinine≦3X UNL.
- Subjects who sign the informed consent form.
Exclusion criteria
- Subjects' LUTS are not BPH-related but associated with such conditions as urethral stricture, prostatitis, neurogenic bladder, or pelvic treatment procedures.
- Subjects who have been treated with pelvis irradiation or pelvic surgery.
- PSA > 10.0 ng/ml, abnormal DRE of the prostate or any suspicion of prostate malignancy. However, those who have a negative prostate biopsy are allowed.
- Active infection or inflammation.
- Considered ineligible by the investigators.
