FDA Rejects Lipocine’s Testosterone Replacement

Share

FDA has sent a complete response letter (CRL) to Lipocine for its LPCN 1021, an oral testosterone product candidate for testosterone replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone. The CRL identified deficiencies related to the dosing algorithm for the label, noting that the titration scheme for clinical practice was significantly different from the titration scheme used in the Phase 3 trial, leading to discordance in titration decisions between the trial and real-world clinical practice.

Lipocine says its next step will be to request a meeting with FDA to understand more fully the issues raised and to agree on a path forward for approval of LPCN 1021. “We are evaluating the content of the CRL, including the FDA recommended actions to bring our NDA in a position for approval, and will work closely with FDA to determine the appropriate next steps for the NDA,” said Lipocine CEO Mahesh Patel.
