Last subject has completed treatment in the first part of Peptonic Medical’s phase 2b VVA study

Stockholm, 1st February 2017. Peptonic Medical AB (publ) - a company developing pharmaceuticals based on oxytocin - today announced that all of the randomized subjects of the first part of the ongoing phase 2b study (main study) now have completed the treatment and exited the study. In this study, the effect of treating menopausal and post-menopausal women suffering from vulvar and vaginal atrophy (VVA) with Peptonic Medcial’s oxytocin gel (Vagitocin®) is being investigated. A glass syringe has been used for storage and administration of the gel.

In total, 161 randomized subjects participated   in   the study. Of these, more than 97 per cent of the subjects have completed the 12-week treatment and attended all of the follow-up visits during the course of the study. This is a very satisfactory outcome and provides a good basis for assessing the effects of the treatment with oxytocin. With the exception of a slower than planned patient recruitment, the study has progressed well and in accordance with the plan and there are no major deviations or treatment related serious adverse effects to report.

The information collected during the study will now be analysed according to the study protocol and initial results are expected before end of March.

“I want to extend my gratitude to all those that have been engaged and contributed to the success so far – not least all the study subjects”, says Johan Inborr, CEO of Peptonic Medical, “It’s going to be   exciting to see the results of this study.”.

About oxytocin

Oxytocin is a peptide hormone that is produced within the neurons of the brain and released in to the blood stream. It is well known for its key role in labour and breast feeding, stimulating the contraction of the uterus and promoting milk ejection. Oxytocin has been used clinically since the 1960s as an IV drip and is also administered as an injection after childbirth to reduce uterine bleeding. More recently, oxytocin has been found to possess additional medicinal benefits as an anti-inflammatory agent, in promoting the healing of tissues as well as the possible reduction in certain types of pain.  

Oxytocin is the active substance of Vagitocin®, which is currently being investigated for the treatment of vaginal atrophy in menopausal women. In this application, the oxytocin gel is administered vaginally.
