AbstractObjectivesTo assess the effectiveness, onset of action and safety of MED3000 gel over a 24-week treatment period in male patients clinically diagnosed with ED.Methods100 male patients clinically diagnosed with ED were randomised into two treatment groups, 50 to MED3000 and 50 to Tadalafil (5mg) in 11 Investigational sites in USA, Poland Georgia and Bulgaria.ResultsBoth Co-Primary end points were achieved (P<0.001) (1) Mean IIEF-EF change from baseline at 24 weeks (2) Minimal clinically important difference (MCID) exceeded at 24 weeks). 61% of MED3000 users exceeded the MCID at 24 weeks The mean IIEF score at weeks 4, 8, 12, 16, 20, 24 was 4.59, 5.20, 5.12, 5.83, 5.57 5.73 Secondary Endpoint 10 minute onset of action FDA agreed standard for achieving a 10 minute onset of action was achieved. A key differentiator from PDEi's Effective in Mild, Moderate and Severe ED MED3000 also delivered a clinically meaningful outcome over 24 weeks in accordance with the Rosen 2, 5 and 7 criteria (Rosen et al 2011)1 in mild, moderate and severe ED subjects Adverse Events (<2 incidences) are detailed in figure 1.Reference1 – Rosen RC et al “Minimal clinically important differences in the erectile function domain in the International Index of Erectile Function Scale Eur Urol 2011;60(5):1010-6ConclusionsMED3000 has been shown to deliver a clinically meaningful response and is fast-acting. It was also shown to be clinically effective in mild, moderate and severe ED. Results were generally consistent with a previously conducted clinical study used for European approval MED3000 was shown to have minimal adverse events. Its “drug-free” formula provides a further margin of safety with no propensity for adverse drug interactions. This profile makes it suitable for OTC use.FDA filing for marketing authorisation as a De Novo medical device occured in October 2022.Conflicts of InterestProfessor David Ralph is a consultant to FMD Tim Holland and Ken James are employees of FMD The study was funded by FMD (Not for promotional purposes in the US).
