What this trial studies

This clinical trial aims to evaluate the efficacy and safety of the drug LIB-01 in treating erectile dysfunction in male adults. Participants will take either LIB-01 or a placebo daily for three days and attend weekly clinic visits for four weeks, with an additional visit at eight weeks for assessments. The study will measure improvements in erectile function and monitor any medical issues arising from the drug. The results will help determine if LIB-01 is a viable treatment option for erectile dysfunction.

Who should consider this trial

Good fit: Ideal candidates are males aged 25 to 65 in stable heterosexual relationships who are motivated to seek treatment for erectile dysfunction.

Not a fit: Patients with clinically significant diseases or those not meeting the inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve erectile function and quality of life for men suffering from erectile dysfunction.

How similar studies have performed: Other studies have shown promise in treating erectile dysfunction with novel pharmacological approaches, suggesting potential for success with LIB-01.

9. History of glaucoma.
10. History of Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION).
11. History of prostatectomy.

17. Use of nitrate medications within 14 days prior to the screening visit.
18. Use of any drug with narrow therapeutic index or drugs that are sensitive substrates, strong inducers or strong inhibitors to CYP3A4 as well as substrates and inhibitors of OATP1B1 or sensitive to substrates to CYP2B6 in accordance with the list provided (see Section 9.6.2.1).
19. Use of oral, injectable, intra-urethral, or topical pro-erectile drugs or supplements, including but not limited to PDE5-Is or prostaglandin E1, or use of devices for ED treatment, within 14 days prior to screening.
20. Primary hypoactive sexual desire.
21. Presence of penile anatomical abnormalities, such as penile fibrosis or Peyronie's disease, which would cause significantly impaired sexual performance, as judged by the Investigator.
22. Insufficient therapeutic effect when using PDE5-Is.
23. History of, or ongoing antiandrogen treatment.
24. Any positive result at the screening visit for serum hepatitis B surface antigen, hepatitis B and C antibodies and/or human immunodeficiency virus (HIV).
