August 27, 2018 updated by: Hyun Jun Park

The Efficacy and Safety of New Herbal Formula (KBMSI-2) in the Treatment of Erectile Dysfunction: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial

Background: KBMSI-2, which is the herbal formular consisted of Ginseng Radix Rubra, Dioscorea tenuipes, Cornus officinalis Sieb. Et Zucc, Lycium Chinese Mill, Curcuma logna Linn, Honey, improved the erectile function by preserving the smooth muscle content and inhibiting the fibrosis of the corpus cavernosum in STZ-induced diabetic rat model. In this study, the researchers investigated the efficacy and safety of the herbal formula (KBMSI-2) in the treatment of ED.

Material and Methods: Patients were instructed to take investigational products (KBMSI-2 6g or placebo) twice a day for 8 weeks at least 1 hour after food intake. The primary efficacy variable was the change in the EF domain scores of the IIEF questionnaire from baseline. Secondary efficacy measures included change in all domain scores of the IIEF from baseline, change in question 2 and 3 of the SEP2,3, from baseline.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

19 years to 40 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

  • age range between 19 and 40 years old;
  • patients were required to be involved in a stable, monogamous relationship with a female sexual partner and having failed >50% of at least four sexual attempts during the run-in period.

Experimental: KBMSI-2 6gm
Patients were instructed to take investigational products (KBMSI-2 6g) twice a day for 8weeks at least 1 hour after food intake
Drug: KBMSI-2
The KBMSI-2 capsules (6gm/capsule) and placebo were provided by Korean Bio Medical Science Institute (Seoul, Korea). KBMSI-2 was analyzed by high-performance liquid chromatography. KBMSI-2 contained major ginsenoside-Rb1: 260.53ug/g, -Rb2: 543.91ug/g, -Rc: 424.92ug/g, -Re: 377.32ug/g, -Rf: 1160.55ug/g, -Rg1: 703.97ug/g, Curcumin 60.73ug/g, Allantoin 98.66ug.g, and Loganin 744.13ug/g. During the study period, two capsules were taken daily for 8 weeks. The placebo capsules were identical in shape, color, and taste.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in the EF domain scores of the IIEF questionnaire from baseline
Time Frame: Baseline, 4weeks, 8weeks
calculated by comparing total scores from questions 1 to 5 and 15 from IIEF questionnaire
Baseline, 4weeks, 8weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in all domain scores of the IIEF from baseline
Time Frame: Baseline, 4weeks, 8weeks

change in question 2 and 3 of the Sexual Encounter Profile (SEP2: Were you able to insert your penis in your partner's vagina? SEP3: Did your erection last long enough for you to have a successful intercourse?) from baseline
