Phase III trial comparing the efficacy and safety of recombinant- or urine-derived human chorionic gonadotropin for ovulation triggering in Japanese women diagnosed with anovulation or oligo-ovulation and undergoing ovulation induction with follitropin-alfa.

ABSTRACT: Aim:Outside of Japan, recombinant-human chorionic gonadotropin (r-hCG) is widely used for the induction of final follicular maturation and early luteinization in women undergoing ovulation induction; whereas in Japan, urine-derived hCG (u-hCG) is predominantly used. The primary objective of this study was to demonstrate the non-inferiority of r-hCG to u-hCG for ovulation induction, as assessed by the ovulation rate. Methods:This was an open-label, parallel-group, randomized, multicenter, phase III trial in Japanese women with anovulation or oligo-ovulation secondary to hypothalamic-pituitary dysfunction or polycystic ovary syndrome, undergoing ovulation induction with recombinant-human follicle-stimulating hormone. The women were randomized (2:1) to receive either a single 250 ?g s.c. dose of r-hCG or a single 5000 IU i.m. dose of u-hCG for ovulation triggering. Results:Eighty-one women were randomized to either r-hCG (n=54) or u-hCG (n=27). Ovulation occurred in 100% of the participants and treatment with r-hCG was observed to be non-inferior to u-hCG for ovulation induction. Overall, the type and severity of adverse events were as expected for women receiving fertility treatment. Conclusion:This study demonstrated that r-hCG was non-inferior to u-hCG for inducing ovulation. Furthermore, r-hCG demonstrated an expected safety profile, with no new safety concerns identified.

Project description:The major limitations associated with gonadotropin-releasing hormone agonist (GnRHa) triggering are inferior clinical outcomes in fresh embryo transfer cycles caused by luteal phase insufficiency following the GnRHa triggering. We included 153 high-risk patients in this study. In group I, the patients received gonadotropin-releasing hormone agonist (GnRHa) trigger + 1,500 IU human chorionic gonadotropin (hCG) support on the oocyte pick-up (OPU) day; in group II, the patients had a dual trigger (GnRHa + 1,500 IU hCG); and in group III (control), 10,000 IU hCG trigger was prescribed for the final oocyte maturation. The levels of LH, estradiol, and progesterone were evaluated in serum on the stimulation starting day, day 6 of stimulation, on the day of the trigger administration, OPU day, days 3 and 5 post-OPU, and day 14 post-ET, as well as in follicular fluid. Progesterone concentration was significantly lower in group I on OPU+5 compared to the hCG group (I vs. III, р = 0.0065). Progesterone levels were significantly lower in group II in serum on OPU+5 compared to groups I and III (I vs. II, р = 0.0068; II vs. III, р = 1.76 × 108). The progesterone levels were significantly higher in follicular fluid in group III compared to the study groups (I vs. III, р = 0.002; II vs. III, p = 0.009). However, no significant differences in clinical outcomes were found between the groups. Then, we divided all women into pregnant and non-pregnant groups and found that estradiol (p = 0.00009) and progesterone (p = 0.000036) on the day of the pregnancy test were significantly higher in the pregnant women group. Also, progesterone on OPU day was significantly higher in the non-pregnant group (p = 0.033). Two cases of moderate ovarian hyperstimulation syndrome (OHSS) late-onset occurred in group I (3.5%, 2/56), no case of moderate/severe OHSS late-onset in group II, and three cases of moderate late-onset in group III (5.7%, 3/53). The low-dose hCG supplementation improves the luteal phase insufficiency after GnRHa triggering, which is confirmed by the comparable pregnancy rates in fresh transfer cycles between the groups. However, low-dose hCG carries a similar risk of OHSS as the full dose of hCG in high-responder patients.

Project description:Purpose:We aimed to compare the efficacy and safety of recombinant human follicle-stimulating hormone (follitropin alfa) and purified urinary human follicle-stimulating hormone (urofollitropin) for ovulation induction in Japanese women with anovulatory infertility;also to verify the noninferiority (in terms of ovulation rate) of follitropin alfa versus urofollitropin. Methods:In a Phase III, multicenter, single-blind, parallel-group study, we enrolled 265 Japanese women aged 20-39 years. The patients were menstruating without apparent ovulation or were amenorrheic (with a positive progestin challenge test), and had failed to conceive with anti-estrogen ovulation-induction therapy. The patients underwent a low-dose step-up regimen using follitropin alfa or urofollitropin with a starting dose of 75 IU. The primary endpoint was the proportion of patients who ovulated (mid-luteal serum progesterone ?5 ng/mL and/or confirmed clinical pregnancy). Secondary endpoints included the proportion of patients with a dominant follicle (?18 mm) and the duration of stimulation. Results:Ovulation occurred in 79.1% and 82.6% of the patients who received follitropin alfa and urofollitropin, respectively, in the full-analysis set (n = 261), and in 79.2% and 82.5% of the per-protocol set (n = 251). The predefined noninferiority criteria for the primary endpoint were achieved. No significant differences were observed in any secondary endpoint. Treatment-emergent adverse events were reported by a similar proportion of patients in each group (follitropin alfa, 53.5%; urofollitropin, 50.0%). Conclusions:No significant difference in the primary efficacy endpoint (rate of ovulation) was observed between follitropin alfa and purified urofollitropin in women with anovulatory infertility who were menstruating or had progestin-positive amenorrhea. The use of treatment holidays in this study prevents comparison of the data with previous trials that utilized consecutive daily doses.
