LPCN 1021: Oral Product Candidate for Testosterone Replacement Therapy

LPCN 1021 is a novel oral product candidate of Testosterone (T) containing Testosterone Undecanoate (TU) that is designed to help restore normal T levels in males for conditions associated with a deficiency or absence of endogenous testosterone.

LPCN 1021 is designed to overcome many of the issues related to TRT products on the U.S. market. LPCN 1021 received a Complete Response Letter from the FDA on June 28, 2016 with two new clinical studies being conducted to address the deficiency cited. LPCN 1021 is being studied for both Primary and Secondary hypogonadism and is targeted to the established chronic US TRT market.
