About
This clinical trial is designed as a randomized, placebo-controlled, single-blind, parallel design, multi-center, phase 2 clinical trial to evaluate the efficacy and safety of GV1001 in patients with benign prostatic hyperplasia. Eligible subjects are randomized into a group out of the three study groups and a placebo group after four weeks of placebo run-in period. Placebo run-in period is concurrently proceeded as a wash-out period for previous treatment of benign prostatic hyperplasia, and a placebo is administered intradermally twice with two-week interval during this period. After that, the randomized subjects receive a study drug and a placebo intradermally seven times with two-week interval by visiting at Week 0, 2, 4, 6, 8, 10, and 12. After the treatment period, the subjects additionally visit at Week 13 and 16, and the efficacy is evaluated at Week 4, 8, 12, 13, and 16, and the safety is evaluated over the 16-week period.

Inclusion and exclusion criteria
[Inclusion Criteria]
All of the following criteria should be satisfied to be enrolled in this clinical trial.
A male at 50 years of age and older
A patient who satisfies the following clinical signs and symptoms of benign prostatic hyperplasia
① A patient with a volume of prostate gland (TRUS) > 30 cc
② A patient with moderate to severe lower urinary tract symptoms with IPSS ≥ 13
③ A patient with 5-15 mL/sec of maximum flow rate (Qmax) measured when urine volume was at least 125 mL
A patient with PSA level < 10 ng/mL (however, if 4 ng/mL < PSA < 10 ng/mL, a person with a biopsy result, confirming that he does not have prostate cancer)
A patient with residual urine volume ≤ 200 mL
A patient with intention of not using drugs which may affect benign prostatic hyperplasia (5-alpha reductase inhibitors, drugs similar to LHRH, alpha blockers, alpha-beta blockers, anticholinergics, antidiuretic hormones, diuretics, PDE-5 inhibitors, beta-3 adrenoceptor antagonists, etc.), drugs affecting immune system (steroids, immunosuppressants), or health functional foods which may affect a prostate gland (saw palmetto, etc.) during the clinical trial period
A patient has to consent not to participate in other clinical trials as a subject during this clinical trial period.
Before enrollment to the study, a patient has to consent to avoid pregnancy by using condoms for 90 days after the end of study participation period and treatment. (However, this is not applied if the patient had vasectomy.) Also, a partner of the patient has to consent to avoid pregnancy by using contraceptive devices or oral contraceptives during the patient's participation in clinical trial and for 90 days after the end of treatment, except if the partner reaches menopause or is surgically sterilized. (Consent should be obtained before visit 4, when necessary.)
[Exclusion Criteria]
If any one of the following is applied, a patient cannot be enrolled in this clinical trial.
[Inclusion Criteria for Randomization]
A patient who satisfies the following clinical signs and symptoms of benign prostatic hyperplasia
① A patient with a volume of prostate gland (TRUS) > 30 cc *
② A patient with moderate to severe lower urinary tract symptoms with IPSS ≥ 13
③ A patient with 5-15 mL/sec of maximum flow rate (Qmax) measured when urine volume was at least 125 mL
A patient with residual urine volume ≤ 200 mL
A partner of the patient has to consent to avoid pregnancy by using contraceptive devices or oral contraceptives during the patient's participation in clinical trial and for 90 days after the end of treatment, except if the partner reaches menopause or is surgically sterilized.
(* In case that additional TRUS examination has been performed after screening, a decision should be made based on the latest result.)
