An AE is any untoward medical occurrence in a participant participating in a clinical trial. The intensity of an AE was classified using the following 3-point scale: mild=awareness of signs or symptoms, but no disruption of usual activity; moderate=event sufficient to affect usual activity (disturbing); or severe= inability to work or perform usual activities (unacceptable). Seriousness refers to death, hospitalization/ prolongation of existing hospitalization, a life-threatening experience, persistent or significant disability/incapacity, or congenital anomaly. The possibility of whether the IMP caused the AE would be classified as: reasonable possibility, no reasonable possibility. All the reasonable possible causality to the IMP were referred to as adverse drug reactions (ADRs). Relatedness of AEs to IMP was assessed by the investigator.

Population: The mITT analysis set consisted of all participants who had successful oocyte retrieval, received at least 1 dose of IMP, and had completed fresh embryo transfer.

Rate of Abnormal Findings in Clinical Laboratory Tests (Clinical Chemistry, Hematology, and Urinalysis)

Participants with at least one abnormal finding in clinical laboratory tests (i.e. abnormal clinical significant \[CS\] values: as assessed by investigator) were reported. Clinical chemistry included: glucose, aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, creatinine, potassium, sodium, chloride, calcium, estimated glomerular filtration rate, and gamma-glutamyl transferase; hematology included: basophils, eosinophils, hematocrit, hemoglobin, lymphocytes, monocytes, neutrophils, platelets, erythrocytes, and leukocytes; urinalysis included: specific gravity, ketones, pH, protein, blood, and glucose.

Time frame: From Day 1 of PVR treatment (day after oocyte retrieval) up to end-of-trial (12 weeks post-oocyte retrieval)

Population: The safety analysis set comprised of all participants treated with IMP.

Rate of Abnormal Findings in Vital Signs

Participants with at least one abnormal finding (i.e. abnormal CS values: as assessed by investigator) in vital signs were reported. Vital signs includes: Weight (kg): decrease of \>=7% from baseline (BL) or increase of \>=7% from BL; Systolic Blood Pressure (SBP): \<=90 mmHg and decrease of \>=20 mmHg from BL or \>=180 mmHg and increase of \>= 20 mmHg from BL; Diastolic Blood Pressure (DBP): \<= 50 mmHg and decrease of \>= 15 mmHg from BL or \>=105 mmHg and increase of \>=15 mmHg from BL; Heart Rate: \<=50 (beats per minute \[bpm\]) and decrease of \>= 15 bpm from BL or \>=120 bpm and increase of \>=15 from BL; Temperature \>= 38.3 degree Celsius.

Time frame: From Day 1 of PVR treatment (day after oocyte retrieval) up to end-of-trial (12 weeks post-oocyte retrieval)

Rate of Ectopic and Heterotopic Pregnancies Following Oocyte Retrieval

Frequency of participants with ectopic and heterotopic pregnancies was presented.
