简要总结
Twenty (20) individuals to be recruited from Ballantyne Medical Associates in Charlotte, NC, without any significant chronic medical history. These patients are general patients for primary care that meet inclusion criteria. Patients will be screened and enrolled by Dr. Bauer and his delegated research staff upon patient consult. Patients will be informed of the purpose of the study including risks, benefits, and alternative treatments to the study. After the potential participants have been given the opportunity to ask questions and have their questions answered, they will be asked to sign an informed consent prior to any study-specific procedures being performed.
Blinded test product will be randomly assigned to study subjects. Test group 1 will be dosed with a placebo capsule taken two capsules once daily Test group 2 will be dosed with Berkeley Life capsules taken two capsules once daily. At baseline, prior to crossover to the other treatment, and at the study's conclusion, NO levels will be monitored using salivary nitric oxide test strips. Both test groups will remain on their existing treatment protocol throughout the study.
详细描述
Patients will be consented and enrolled in the study. A complete medical history and focused physical examination will be conducted and documented and NO levels will be measured using salivary test strips.
Twenty (20) patients with low NO levels will be enrolled and will be randomly assigned to group 1 or group 2.
Once enrolled, patients will be required to complete a subjective questionnaire (the International Index of Erectile Function (IIEF)), EHS Score questionnaire and a Quality of Life (QOL) survey. Patients will be instructed to take 2 Berkeley Life capsules once daily or the placebo based on randomization. The (IIEF) was developed by Rosen and colleagues in 1997 as a multidimensional, 15-item, self-administered questionnaire with the goal of assessing five domains of male sexual function including erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction. The erectile function domain of the IIEF (IIEF-EF) contains 6 questions which the patient answers on a scale from 1 (never or almost never) to 5 (almost always or always), providing a total score of 6 to 30 points. The questions concern erectile frequency, firmness, penetration ability, maintenance frequency, maintenance ability, and erection confidence. Based on a controlled study of 1,151 men taking sildenafil in order to establish cutoff scores for the IIEF-EF, a score of 26 or greater is defined as normal function, mild ED is a score from 22 to 25, mild to moderate ED 17 to 21, moderate ED 11 to 16, and severe ED 6 to 10.
Patients will be sent home with instructions to take 2 Berkeley Life capsules once daily in combination with their existing treatment protocol and then return on day 60, returning all unused test product.
The subject should be willing to self-administer 2 capsules daily and be willing to, upon waking in the AM, self-test with strip and record on a pre-print sheet the test strip color, followed by self-administration of capsule(s) and then at 2 hours self-test again and record on a pre-print sheet the test strip color.

研究组 & 干预措施
Nitric Oxide
Upon enrollment, patients will complete the IIEF questionnaire, EHS Score questionnaire and the Quality of Life survey.
Patients will be sent home with instructions to take 2 Berkeley Life capsules once daily (in this case Active NO), in combination with their existing treatment protocol (Tadalafil) and then return on day 60, returning all unused test product.
After 60 days of taking the active ingredient + tadalafil, patients will repeat the IIEF questionnaire, EHS Score questionnaire and the Quality of Life survey.
After a 4 week wash out, patients will be crossed over to the placebo group and given the other combination.
After 60 days of both combinations, placebo and active, patients will repeat the IIEF questionnaire, EHS Score questionnaire and the Quality of Life survey
干预措施: Nitric Oxide (Dietary Supplement)

结局指标
主要结局
Erection Hardness Score
时间窗: Initial, 2 months post first arm, 2 months post second arm
The Erection Hardness Scale (EHS) involves a 1-4 response to a single question to assess firmness of erection, where 3 is sufficient for penetration and 4 is a rigid erection
International Index of Erectile Function
时间窗: Initial, 2 months post first arm, 2 months post second arm
The (IIEF) was developed by Rosen and colleagues in 1997 as a multidimensional, 15-item, self-administered questionnaire with the goal of assessing five domains of male sexual function including erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction \[17\]. The erectile function domain of the IIEF (IIEF-EF) contains 6 questions which the patient answers on a scale from 1 (never or almost never) to 5 (almost always or always), providing a total score of 6 to 30 points. The questions concern erectile frequency, firmness, penetration ability, maintenance frequency, maintenance ability, and erection confidence. Based on a controlled study of 1,151 men taking sildenafil in order to establish cutoff scores for the IIEF-EF, a score of 26 or greater is defined as normal function, mild ED is a score from 22 to 25, mild to moderate ED 17 to 21, moderate ED 11 to 16, and severe ED 6 to 10.
