Design outcomes

Primary

MeasureTime frame
Main Objective: Evaluate non-inferiority of a double ovarian stimulation using two sucessive doses of corifolltropin alfa (150 micrograms) versus two conventional controlled ovarian hyperstimulation cycles, in poor-responder patients defined according to Bologna Criteria, in terms of total number of oocytes obtained.; Secondary Objective: a) Evaluate non-inferiority of accumulative clinical pregnancy rate and live birth rate, as well as other secondary efficacy outcomes (duration of stimulation, total dose of gonafotropins, serum estradiol on HCG day, number of total and MII oocytes, number of fertilized oocytes, normal fertilization rate, number of cleaving embryos, number of total and top quality embryos, clinical pregnancy rate per randomized patient and per embryo transfer). b) Compare, with exploratory intention, safety, and tolerability outcomes as cancellation rate due to low or excessive response, oocyte atresia after ICSI, abnormal oocoye fertilization, total or partial fertilization failure, number of non-survival thawed embryos, number of post-thawed non-developing embryos, miscarriage after weeks of pregnancy, adverse reactions rate. b) Comparative cost-efectiveness analysis c) Comparative analysis of psyco-emotional effects of stimulation treatments ;Primary end point(s): Number of total retrieved oocytes; Timepoint(s) of evaluation of this end point: The main timepoint of evaluation will be embryo transfer phase of treatment. If embryo transfer is not reached as a result of any of the following causes, respective timepoints of evaluation will be: a) After cancelation of second stimulation, if this event occurs b) After second oocyte retrieval, if no oocytes are recovered c) After confirming absence of fertilization or abnormal fertilization in all recovered oocytes d) After confirming divisional
