VivaGel® BV treatment clinical submission under rolling submission

21 December 2017

Melbourne, Australia; 21 December 2017: Starpharma (ASX: SPL, OTCQX: SPHRY) today announced that it has completed the VivaGel® BV treatment clinical section of the NDA clinical module, which will be submitted to the FDA under Starpharma’s rolling submission on Friday 22 December 2017 (US time).

 

The clinical module of the NDA is the fourth of five modules to be submitted and accounts for a major part of the overall submission. The FDA has also completed a preliminary review of the proposed clinical datasets and has confirmed that the intended format and presentation of that data is acceptable.

 

Included in the BV treatment section is data from Starpharma’s two phase 3 treatment clinical trials of VivaGel® BV conducted in 2012. Efficacy data from these trials complies with the revised FDA guidance for the treatment of bacterial vaginosis (BV) issued in mid-2016. The revised FDA guidance recommends that the primary efficacy endpoint for products for treatment of BV should be assessed 7–14 days after commencing treatment. This timing aligns with the data from Starpharma’s 2012 BV treatment efficacy trials, which showed highly statistically significant clinical cure of BV when patients were assessed 2–5 days after end of treatment (9‑12 days after commencing treatment).

 

Starpharma’s NDA submission for VivaGel® BV is for both BV indications - BV treatment and prevention of recurrent BV (rBV). As previously announced, the first three of five modules of the NDA were submitted in November, and it’s expected that the final clinical data and remaining module will be submitted in the near future. Based on experience with other products granted Fast Track status, review time is expected to be approximately 6-8 months. The VivaGel® BV NDA submission and review process benefits from FDA’s Fast Track status and Qualified Infectious Disease Product (QIDP) designation which are designed to accelerate the regulatory process and secure rapid approval and early market access for products that address unmet medical needs.

 

VivaGel® BV is already approved for sale in Europe and Australia. In Australia VivaGel® BV is licensed to Aspen Pharmacare, who will launch the product in the near future. Starpharma is actively engaged in licensing negotiations for commercial rights to VivaGel® BV across multiple regions. A number of term sheets and draft contracts are currently under discussion with parties, including major global and regional companies as well as companies specialising in women's health. These negotiations have been impacted positively by Fast Track status and QIDP designation, successful phase 3 rBV results and most recently, TGA approval, which is also relevant for many markets outside Australia.

 

Dr Jackie Fairley, Starpharma CEO, commented: “We are pleased with the significant progress of our rolling NDA submission and look forward to its completion soon. We anticipate that the prevention of rBV data along with the final module will be submitted in the New Year, by which time the volume of the NDA is likely to exceed 100,000 pages. This submission is a major milestone for the Company and we’re also excited to see such good progress on the commercial negotiations for this breakthrough product for BV.”

About Bacterial Vaginosis (BV)

Bacterial vaginosis is the most common cause of vaginal infection for women of childbearing age, and affects around 30% of women in the US. It is a highly recurrent condition with 50-60% of sufferers having it recurrently. BV is caused by an imbalance of naturally occurring bacterial flora (the usual bacteria found in a woman's vagina). Smoking, the use of some hygiene products and several other risk factors are linked to a higher risk of developing BV. Current therapies for BV are inadequate and have many unpleasant side-effects, there are also no approved products in the US for rBV making VivaGel® BV a first-in-class therapy supported by large, randomised clinical studies.
