An open-label investigation using MED3000 gel or tadalafil (5 mg) tablets in the treatment of erectile dysfunction in patients from 22 to 70 years of age. Each patients will be expected to participate for up to 30 weeks. Eligible patients will be randomised to receive either MED3000 gel or tadalafil (5 mg) tablets in a 1:1 ratio.

To demonstrate the efficacy of various doses of MED2005 versus placebo in male patients with clinically diagnosed erectile dysfunction, and to evaluate the long-term efficacy and safety (12 months) of MED2005.

Futura Medical Developments Ltd (FMD) are developing a gel formulation of GTN (MED2005) as a topical treatment for ED delivered using DermaSys®, a versatile and bespoke technology. Treatment requires the application of a small quantity of gel (approx 300 mg), containing a fixed dose of GTN, to the glans of the penis. Pharmacokinetic studies in healthy volunteers indicate rapid absorption of the drug and low systemic exposure, reducing the risk of adverse events (such as headache) commonly associated with GTN therapy.
The purpose of this study is to demonstrate similar or lower bioavailability of GTN from MED2005 (test IMP) with that from Nitrostat (reference IMP).
The study will be conducted in two parts (Part 1 and 2). Part 1 will be conducted in 30 subjects and Part 2 will be conducted in 10 subjects. Part 1 will compose of a pre-study screen, followed by six treatment periods and a post-study follow-up.
Part 2 will compose of a pre-study screen, followed by two treatment periods and a post-study follow-up. Subjects can only participate in either Part 1 or 2 of the study (not both).
