US FDA requests further data for VivaGel® BV approval
- FDA has advised Starpharma it requires confirmatory clinical data prior to approval
- Starpharma plans to meet with the FDA as soon as possible to discuss the additional data required for approval
- In parallel with FDA discussions, Starpharma and its non-US partners are committed to the active commercialisation of VivaGel® BV in non-US regions; VivaGel® BV is already approved in the EU and Australia, and has been licensed in most regions around the world, with launches planned in 2019
- Regulatory processes underway continue in other markets and are independent of FDA approval
Melbourne, Australia; 27 December 2018: Starpharma (ASX: SPL, OTCQX: SPHRY) today received advice from the US FDA that it will require confirmatory clinical data prior to approving VivaGel® BV for treatment of bacterial vaginosis (BV) and the prevention of recurrent BV (rBV).
Starpharma is currently evaluating the details of FDA’s advice but anticipates being able to address the issues raised through the generation of confirmatory clinical efficacy data. The company is requesting a meeting with the FDA as soon as practicable to discuss the data required and Starpharma is keen to secure approval with minimal delay. Encouragingly, the FDA did not identify any approvability issues in relation to the safety, manufacturing or quality of VivaGel® BV. Starpharma will also be discussing next steps with its US partner, ITF Pharma, and any potential impact on its US licence.
VivaGel® BV is already approved in the EU and Australia, and regulatory processes currently underway continue in other markets and are completely independent of FDA approval. Starpharma has licensed VivaGel® BV to Mundipharma for most non-US regions around the world. Initial launches for VivaGel® BV will proceed as planned in multiple Mundipharma regions (including Europe) and Australia during the first half of 2019.
Dr Jackie Fairley, CEO of Starpharma, said: “Clearly we are surprised and extremely disappointed with the FDA's requirement for confirmatory data in order to approve the NDA for VivaGel® BV considering the comprehensive nature of the data provided. However, we are greatly encouraged by the FDA’s acknowledgement of the significant unmet medical need that would be fulfilled by the product, and they have expressed a desire to work with Starpharma to secure approval in order to make VivaGel® BV available to women in the US as soon as possible”.
“Aside from VivaGel® BV, Starpharma will also continue to commercially exploit its deep portfolio of DEP® drugs, including DEP® docetaxel, DEP® cabazitaxel, DEP® irinotecan and a range of other internal and partnered programs, including the novel oncology agent AZD0466, which is being developed under licence by AstraZeneca”.
“Importantly for the dendrimer component of VivaGel® BV, which is the first of its kind to be reviewed by the FDA under an NDA, no issues were raised in relation to the safety, manufacturing or quality of the product. We stand by the compelling data package submitted to the FDA, which has supported approvals in other major markets and is expected to enable multiple additional approvals throughout non-US regions. Starpharma is committed to the active commercialisation of VivaGel® BV in these regions as well as commercialisation of our DEP® portfolio, in parallel with addressing the requirements for approval in the US.”, concluded Dr Fairley.
In their advice, the FDA acknowledged the demonstrated efficacy benefits of VivaGel® BV although they have requested confirmatory data prior to approval. The FDA’s acknowledgment of the significant unmet medical need for an approved product to manage rBV is consistent with the strong positive feedback from key opinion leaders, OBGYNs and patients in the US. Starpharma knows that BV patients, US clinicians and BV key opinion leaders will be disappointed with the FDA’s decision on VivaGel® BV which will delay access to the product in the US. Starpharma looks forward to working with the FDA to address their additional requirements as soon as practicable.

About Bacterial Vaginosis (BV)
BV is the most common cause of vaginal infection for women of childbearing age and affects one in three women in the US. It is a highly recurrent condition with almost two thirds of sufferers experiencing repeated episodes. BV is caused by an imbalance of naturally occurring bacterial flora (the usual bacteria found in a woman's vagina). Current therapies for BV are inadequate and have many unpleasant side-effects, there are also no approved products in the US for preventing recurrent BV.
