Stakeholder Opinions: Sexual Dysfunction - The quest for the new Viagra continues
http://www.reportlinker.com/p0184975/Stakeholder-Opinions-Sexual-Dysfunction---The-quest-for-the-new-Viagra-continues.html
Introduction
Drug developers interested on the sexual dysfunction market are searching for the next Viagra. Companies are focusing on premature ejaculation and female hypoactive sexual desire disorder, which are suggested to be as prevalent as erectile dysfunction. As products advance through the pipeline, there are several challenges that will have to be addressed in order to succeed in these markets.
Scope
*Overview of erectile dysfunction, premature ejaculation and female sexual dysfunction disorders including epidemiology and key unmet needs.
*Summary of the drug classes currently used for the different sexual dysfunction disorders and an update of the latest proposed treatment guidelines.
*Evaluation of marketed brands and pipeline agents for erectile dysfunction, premature ejaculation and female sexual dysfunction disorders.
*Insights from interviews with seven leading US and European key opinion leaders in the field of male and female sexual dysfunction.
Highlights
The erectile dysfunction market will remain the most attractive and accepted one among the different sexual dysfunction disorders for the foreseeable future, although Johnson & Johnson is well positioned to develop the premature ejaculation area with the launch of Priligy (dapoxetine) in the EU.
Companies entering the sexual dysfunction market will have to follow the example of Viagra (sildenafil, Pfizer) and invest heavily in direct to consumer marketing in the US. A strong marketing message will be vital to raising awareness and beginning the campaign to destigmatize the different disorders.
There is high R&D risk in the associated with the development of drugs for female sexual dysfunction due to the lack of clear disorder definition and trial endpoints, the strong placebo effect of drugs and the scrutiny of regulatory bodies. As such Boehringer Ingelheim's flibanserin and BioSante's LibiGel (testosterone) approval is not guaranteed.
Reasons to Purchase
*Understand the prevalence of erectile dysfunction, premature ejaculation and female sexual dysfunction.
*Identify the key clinical unmet needs in the treatment of male and female sexual dysfunction as determined by interviewed key opinion leaders.
*Evaluate the potential of key strategies companies can employ to increase their presence in the sexual dysfunction disorder markets.
