Trial to Assess the Clinical Efficacy and Safety of MSJ-0011 in Inducing Ovulation in Anovulatory or Oligo-ovulatory Japanese Women

Study Overview
=================
Brief Summary
-----------------
This is an open-label, parallel-group, randomized, multicenter Phase III trial to compare the efficacy and safety of a single 250 microgram (mcg) subcutaneous dose of MSJ-0011 to a single 5,000 international units (IU) intramuscular dose of urinary human chorionic gonadotropin (hCG) in inducing ovulation in Japanese women diagnosed with anovulation or oligo-ovulation. Ovulation induction therapy will be undertaken with follitropin alfa. The primary objective is to show that MSJ-0011 is non-inferior to urinary hCG, as assessed by the ovulation rate.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: MSJ-0011<br> | Drug: MSJ-0011<br>* Subjects who underwent ovarian stimulation with follitropin alfa according to a low-dose step-up protocol for maximum of 28 days will receive a single dose of 250 microgram (mcg) MSJ-0011 (choriogonadotropin alfa [recombinant human Chorionic Gonadotropin, r-hCG]) subcutaneously (SC) within 32 hours after the last dose of follitropin alfa administration unless dominant follicle reached a mean diameter of greater than or equal to (>=) 18 millimeter (mm); not more than 3 follicles each with a mean diameter of >=16 mm and serum Estradiol (E2) level within an acceptable range for the number of follicle present, and not more than 2,000 picogram per milliliter (pg/mL).<br>Drug: Follitropin alpha<br>* Low-dose step-up protocol involves starting dose of follitropin alfa as 75 International Units (IU) subcutaneously per day ,increments by 37.5 IU every 7 days (Day 8, 15, 28) will be done if no ovarian response will be observed for maximum of 28 days.<br>|
| Active Comparator: urinary hCG<br> | Drug: urinary hCG (u-hCG)<br>* Subjects who underwent ovarian stimulation with follitropin alfa according to a low-dose step-up protocol for maximum of 28 days will receive a single dose of 5,000 IU u-hCG intramuscularly dose within 32 hours after the last dose of follitropin alfa administration unless dominant follicle reached a mean diameter of >=18 mm; not more than 3 follicles each with a mean diameter of >=16 mm and serum E2 level within an acceptable range for the number of follicle present, and not more than 2,000 pg/mL.<br>Drug: Follitropin alpha<br>* Low-dose step-up protocol involves starting dose of follitropin alfa as 75 International Units (IU) subcutaneously per day ,increments by 37.5 IU every 7 days (Day 8, 15, 28) will be done if no ovarian response will be observed for maximum of 28 days.<br>|

| --- | --- | --- |
| Percentage of Subjects With Ovulation Mid-luteal Serum Progesterone (P4) Level of Greater Than or Equal (>=) 5 Nanogram Per Milliliter (ng/mL) or Clinical Pregnancy | Ovulation was defined as mid-luteal serum progesterone level of >= 5 ng/mL or clinical pregnancy. Clinical pregnancy was defined as the presence of at least a fetal sac on transvaginal ultrasound (TVUS). | Mid-luteal phase progesterone assessed (Day 5 to 10) or clinical pregnancy (Day 35 to 42) post hCG treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |

Clinical pregnancy was defined as the presence of at least a fetal sac on TVUS. | Mid-luteal phase progesterone assessed (Day 5 to 10) or clinical pregnancy (Day 35 to 42) post hCG treatment | 
| Mid-luteal Endometrial Thickness | Endometrial thickness was measured using TVUS. | Day 5 to 7 post hCG treatment | 
| Percentage of Participants With Biochemical Pregnancy | Percentage of subjects with biochemical pregnancy was assessed. Biochemical pregnancy was defined as any miscarriage without any evidence of a fetal sac on TVUS on the Day 35 to 42 post hCG treatment, but with a positive serum β-hCG pregnancy test on Day 15 to 20 post hCG treatment (Beta-hCG level greater than [>] 10 IU/Liter) | Day 35 to 42 post hCG treatment |
