The FDA accepted for review a new drug application for the steroidogenesis inhibitor levoketoconazole for the treatment of endogenous Cushing’s syndrome, according to an industry press release.

“We are pleased with the FDA’s acceptance for filing of the Recorlev new drug application,” John H. Johnson, CEO of Strongbridge Biopharma, said in the release. “We believe this decision reflects the comprehensive clinical evidence that went into the NDA submission, including the positive and statistically significant efficacy and safety results from the multinational phase 3 SONICS and LOGICS studies evaluating Recorlev as a potential treatment option for adults with endogenous Cushing’s syndrome. We are advancing our commercial readiness plans and look forward to potentially bringing a new therapeutic option to the Cushing’s syndrome community in the first quarter of 2022.”

As Healio previously reported, top-line findings from the LOGICS study demonstrated that levoketoconazole (Recorlev, Strongbridge Biopharma) improved and normalized morning urinary free cortisol concentrations for adults with endogenous Cushing’s disease compared with placebo.

The drug was generally well tolerated, with safety data mirroring those from the earlier phase 3 SONICS trial.

Endogenous Cushing’s syndrome — caused by chronic hypercortisolism — is rare, with estimates ranging from 40 to 70 people per million affected worldwide, according to the National Institute of Diabetes and Digestive and Kidney Diseases.

The FDA set a Prescription Drug User Fee Act target action date of Jan. 1, 2022, for levoketoconazole, according to the company. The FDA letter made no mention of a plan to hold an advisory committee meeting.
