Solosec™ Now Approved

On September 18th, 2017, Symbiomix Therapeutics announced that the U.S. Food and Drug Administration (FDA) had approved its lead product Solosec™ (secnidazole) 2g oral granules for the treatment of bacterial vaginosis (BV) in adult women.

Following approval on September 15, 2017, Solosec is anticipated to be commercially available in early 2018.

Solosec™ has been designated as a Qualified Infectious Disease Product (QIDP) by the U.S. Food and Drug Administration (FDA) for the treatment of BV. QIDP designation creates incentives for the development of new drugs intended to treat serious or life threatening infections and makes Solosec™ eligible for certain benefits including at least 10 years of market exclusivity.

The FDA approval was supported by a comprehensive set of studies, including two pivotal trials in BV and an open label safety study, which found efficacy for single-dose secnidazole 2g. All treatment-emergent adverse events were mild or moderate in intensity; no serious adverse events were reported, and no patients discontinued treatment due to adverse events. [6,7]

SOLOSECTM (secnidazole) 2g oral granules is a 5-nitroimidazole antimicrobial agent indicated for the treatment of bacterial vaginosis in adult women.
