Tolmar Pharma Drug Approved for Early Puberty
FDA has approved a Tolmar Pharmaceuticals NDA for Fensolvi (leuprolide acetate) for injectable suspension for treating pediatric patients two years of age and older with central precocious puberty (CPP). The rare disease is defined as the onset of puberty before age eight in girls and before age nine in boys, according to the company. CPP patients are at risk of having significantly short stature as adults in addition to social, psychological and emotional issues, it says.
Tolmar says that leuprolide acetate is the most widely used treatment for CPP. Fensolvi uses a propietary polymeric gel technology that forms an in-situ solid after injection and releases leuprolide acetate in a sustained and controlled manner over time. “This polymeric gel technology enables a small volume of injection of only 0.375mL, subcutaneous administration, and a six-month dosing cycle,” the company says.
Approval was based on data from a single-arm Phase 3 study in 64 children with CPP. The study met its primary endpoint, according to Tolmar, with 87% achieving a serum luteinizing hormone target concentration at six months post injection. The study also demonstrated that Fensolvi suppressed sex hormones to pre-pubertal levels, and stopped or reversed the progression of clinical signs of puberty, the company says.
