Clarus Wants FDA Testosterone-Ester Guidance
Clarus says FDA should establish clear written guidance on safety and efficacy standards required for oral testosterone-ester prodrugs as testosterone replacement therapy for adult men with a deficiency or absence of endogenous testosterone. A company petition also asks that the agency not approve any pending NDA for an oral testosterone-ester to treat male hypogonadism that fails to meet the approval standards listed in the petition.
The company says FDA should address the specific criteria that oral testosterone-ester prodrugs must meet regarding primary efficacy, secondary efficacy, dose titration, concordance, food effect, and characterization of post-collection conversion of specific testosterone-ester to testosterone in blood of men treated with oral testosterone-ester to assess clinical testosterone response.
FDA approved 3/27 Clarus’ Jatenzo, the first U.S. oral testosterone-ester product indicated for testosterone replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone.
