Design outcomes

Primary

MeasureTime frame
Main Objective: To show that the efficacy of LeukoNorm CytoChemia® applied as supportive immunotherapy within IVF/ICSI-treatment is superior to placebo with respect to an increased pregnancy rate;Secondary Objective: To investigate the safety and tolerability of LeukoNorm CytoChemia® injection within a therapy scheme of 10 intra-muscular injections;Primary end point(s): The primary efficacy variable will be the rate of successful pregnancies, measured by clinical methods (transvaginal sonography). Thereby a positive heart activity within at least one intrauterine embryonic sac will be regarded as successful pregnancy.
