Subdermal Implant-bioabsorbable Oxandrolone Pellet For Rehabilitation Following Anterior Cruciate Ligament (ACL) Surgical Reconstruction
96 patients around the world
Available in Brazil
This is a phase II, randomized, double-blind, placebo-controlled, multicenter clinical
study designed to evaluate the safety and tolerability profile of the absorbable
oxandrolone implant as an adjuvant treatment in rehabilitation following anterior
cruciate ligament (ACL) reconstruction surgery. The primary safety outcome will be the
incidence of serious adverse events (SAEs) collected through spontaneous reports and/or
clinical findings over 24 weeks after randomization (subdermal insertion of the
absorbable oxandrolone implant). The exploratory evaluation of the efficacy of the
absorbable oxandrolone implant will compare the use of oxandrolone implant with a placebo
pellet in the rehabilitation of patients after ACL reconstruction surgery will be based
on its effects on muscle mass recovery, muscle strength, and functional capacity.
