A Multicentre, Randomised, Double-blind, Placebo-controlled Proof of Concept Study to Compare the Efficacy and Safety of r-hLIF (Emfilermin) for Improving Embryo Implantation Following in Vitro Fertilization (IVF) and Embryo Transfer (ET) in Women With Recurrent Implantation Failure

The primary objective of the study was to provide further clinical and statistical evidence of the efficacy of r-hLIF, in comparison with placebo, administered during the luteal phase after IVF and ET for improving embryo implantation in infertile women with a history of at least 2 implantation failures following transfer of fresh embryos. The secondary objective of the study was to assess the safety profile of r-hLIF in the proposed indication.
