Standard treatments include orallyadministered non-steroidal anti-inflammatory (NSAID) drugs, pain-killers andhormone therapy to bring about symptomatic relief. PSD508 is a proprietary delivery form of a well characterised NSAID, which isadministered intra-vaginally utilising technology which Plethora licensed fromMetris Therapeutics Limited in 2006. This novel approach has the potentialbenefit of allowing women to access a convenient "on-demand" treatmentcontaining an NSAID while minimising systemic exposure to the drug and therebylowering the risk of side effects which limit the usefulness of existingtherapies. Although the technology is being evaluated in dysmenorrhoea, it mayhave much wider utility in the treatment of uro-gynaecological disorders wherethere is little or no effective therapy, e.g. endometriosis and dyspareunia. Study details The study was designed to confirm an earlier proof of concept study. It is a 'gold standard' double-blind, placebo-controlled, multiple-dose crossover studycomparing the efficacy of intra-vaginally delivered PSD508 to that of oral NSAIDand placebo in relieving menstrual-associated pain. This study is taking placeacross three consecutive menstrual cycles, allowing the trial to be completed inthe shortest possible time frame. The study will also add to the extensiveexisting clinical data on the safety and tolerability of PSD508. A total of 159patients have been enrolled into the study at 3 centres in the UK. Dr. Mike Wyllie, CSO of Plethora, commented: "This study was initiated in December 2007 and the ease with which we haverecruited and enrolled patients is indicative of the large patient populationwhich is poorly served by existing treatment options and it is also a measure ofthe acceptability of this product as a patient-friendly drug delivery platform.The conclusion of this study, when the outcome is reported in full later thisyear, will also end our period of significant investment in Phase II studies inour women's health portfolio. These include PSD503 for the treatment of stressurinary incontinence, PSD506 for overactive bladder and PSD597 for the treatmentof interstitial cystitis; all of which are now the subject of early stagelicensing discussions."
