Abstract
BACKGROUND Personalisation strategies of ovarian stimulation for in vitro fertilisation (IVF)/ intracytoplasmic sperm injection (ICSI) treatments using exogenous follicle-stimulating hormone (FSH) have been extensively studied over the past 20 years. This research aimed to develop a FSH population pharmacokinetic (PPK) model taking into account the contribution of gene polymorphisms in Chinese reproductive-age women. METHODS Data from 173 patients undergoing GnRH agonist down-regulation long protocols of IVF/ICSI treatment were collected. PPK analysis was subsequently conducted using the nonlinear mixed-effect model (NONMEM) software. Several covariates, including 18 single nucleotide polymorphisms, demographic factors and biological characteristics, were evaluated. The final PPK model was extensively validated using bootstrapping and normalised prediction error distribution, as well as external validation on an independent group of 35 patients. RESULTS FSH PPK was accurately described by a one-compartment model with first-order absorption. The typical population value of apparent clearance was estimated to be 0.81 L/h [relative standard errors (RSE) 5.3%] with an inter-individual variability (IIV) of 16.0%. The typical apparent distribution volume was 8.36 L (RSE 9.7%, 59.7% IIV), and the absorption rate constant was estimated to be 0.0444 h-1 (RSE 9.1%). Body weight, basal prolactin concentration and the gene ADIPOQ (rs1501299) showed a significant covariate effect on the FSH clearance rate and exposure concentration. Genotypes of THADA (rs12478601) significantly influenced the distribution volume. Simulation results indicated that patients with the TT genotype of THADA (rs12478601) required a longer time to reach steady state and had less fluctuation in FSH levels. Model evaluations showed that the final model accurately and precisely described the observed data and demonstrated effective prediction performance. CONCLUSION PPK models of FSH have been developed, which could potentially be used for FSH dosage individualisation in the clinical setting.

Pharmacokinetics and Safety of Follitropin Delta in Gonadotropin Down-Regulated Healthy Chinese Women. Clin Drug Investig 2023; 43:37-44. [PMID: 36478528 PMCID: PMC9834375 DOI: 10.1007/s40261-022-01232-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/17/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND Follitropin delta, a novel recombinant follicle-stimulating hormone (rFSH) preparation derived from a human cell line, has different pharmacokinetic and pharmacodynamic properties compared with existing rFSH preparations expressed by Chinese hamster ovary cells (CHO). OBJECTIVES The objective of this study was to assess the pharmacokinetic characteristics, dose proportionality, and safety of follitropin delta in healthy Chinese women. METHODS This was a phase I, randomized, open-label study. Twenty-four healthy Chinese women were randomized (1:1:1) to receive a single subcutaneous administration of follitropin delta 12, 18, or 24 μg. The pharmacokinetic parameters (maximum observed serum concentration [Cmax], time to reach Cmax [tmax], area under the serum concentration-time curve from dosing to infinity [AUC∞], and elimination phase half-life [t½]) of follitropin delta were derived using noncompartmental analysis. RESULTS Following a single subcutaneous administration of follitropin delta 12, 18, or 24 μg, mean Cmax (0.388, 0.677, and 0.825 ng/mL, respectively) and AUC∞ (41.3, 62.9, and 83.1 h·ng/mL, respectively) increased in a dose-proportional manner. The median tmax was 24 h, and the mean t½ was in the range of 50.5-60.9 h. All treatment-related adverse events were categorized as mild, except for one case of urticaria from the follitropin delta 18-μg dose group which was considered moderate. Only one woman presented with elevation of alanine transaminase and aspartate aminotransferase at the follow-up visit, which was reported as a treatment-emergent adverse event. There were no injection-site reactions and none of the participants showed any confirmed presence of treatment-induced anti-FSH antibodies. CONCLUSIONS The administration of single doses of follitropin delta to healthy Chinese women demonstrated dose-proportional pharmacokinetics over the dose range of 12-24 μg, and these doses were well tolerated. CLINICAL TRIAL REGISTRATION Clinicaltrials.gov registration no. NCT04150861.

Abstract
OBJECTIVE KN015 is a long-acting, recombinant human follicle-stimulating hormone Fc fusion protein that induces follicle development. This first-in-human study evaluated the effect of KN015 on healthy, pituitary-suppressed women and examined its pharmacokinetics, pharmacodynamics, and tolerability. METHODS This phase I study was a double-blind, randomized, and placebo-controlled design with a single ascending dose (20, 40, and 60 μg, respectively). RESULTS After subcutaneous administration of a single dose, the maximum serum KN015 concentrations reached 1.57, 2.78, and 3.62 ng/mL, respectively, after baseline adjustment. Over this dose range, the median Tmax occurred at 240-312 h, and the half-life (t½) was 752-1160 h. Dose proportionality was shown across the studied dose range. In most subjects, follicular growth was observed, and the number and diameter of the follicles increased with an increasing dose. In the 40-μg and 60-μg groups, the mean numbers of follicles with a diameter of ≥17 mm were 3 and 4, respectively. There was no significant difference in adverse events between the KN015 and placebo groups. KN015 antibody was not detected in any of the dosage groups. CONCLUSION The administration of a single ascending dose of KN015 was tolerated and able to induce follicular growth. TRIAL REGISTRATION This trial is registered at the Chinese Clinical Trials website (http://www.chinadrugtrials.org.cn/index.html # CTR20160741) and ClinicalTrials.gov (https://clinicaltrials.gov/ # NCT03192527).

Abstract
It is a challenge to obtain enough oocytes during in vitro fertilization (IVF) in women who have a poor ovarian response (POR) in achieving conception. We have adopted the characteristics of the first uterine pass effect, which we pioneered in employing the vaginal administration of gonadotropins in women receiving IVF treatments. In our previous study employing vaginal administration, faster absorption and slower elimination of gonadotropins were demonstrated, and, female subjects presented proper ovarian follicle growth and pregnancy rates. In this study, during 2016–2020, 300 to 675 IU of gonadotropins were administered vaginally every three days in 266 POR women for their controlled ovarian hyperstimulation (COH). The injections were performed with needles angled at 15–30° towards the middle-upper portions of the bilateral vaginal wall, with an injection depth of 1–2 mm. For the COH results, these women, on average, received 3.0 ± 0.9 vaginal injections and a total dose of 1318.4 ± 634.4 IU gonadotropins, resulting in 2.2 ± 1.9 mature oocytes and 1.0 ± 1.2 good embryos. Among these embryos, 0.9 ± 1.0 were transferred to reach a clinical pregnancy rate of 18.1% and a live birth rate of 16.7%. In conclusion, the intermittent vaginal administration of gonadotropins proved to be effective in POR women for their IVF treatments.

Abstract
CONTEXT Gonadotropins can be administered every 5 days under intradermal injection in in vitro fertilization (IVF) treatment. OBJECTIVE To explore the effectiveness of intradermal injection of recombinant human FSH (rhFSH) for women undergoing IVF. METHODS Women who received their first IVF treatment enrolled in this prospective intervention in 2018. All women received a bolus of 900 IU rhFSH intradermally at day 2 of the treatment cycle followed by additional dosage of rhFSH at day 7 and/or day 10. The main outcome measures included the total dose of rhFSH and number of injections required, sequential serum FSH level detected, and number of mature oocytes retrieved. RESULTS Seventy women completed the study. On average, 2.31 ± 0.73 injections and 1662 ± 397 IU of rhFSH were administered. While the baseline FSH level was 5.6 ± 2.2 IU/L, the serum concentrations of FSH after rhFSH administration were 35.3 ± 7.0 on the first day (24 hours) and 10.7 ± 3.7 IU/L on the fifth day (120 hours). A total of 10.5 ± 6.6 mature oocytes were retrieved, resulting in 7.3 ± 5.1 pronuclear embryos; 1.8 ± 0.6 embryos were transferred to the uterus. Our findings resulted in 72% fertilization, 91% cleavage, 31% implantation, and 36% live birth rates. Although fewer larger follicles were found, noninferiority results were noted in the mature oocytes retrieved, good embryos available, and clinical pregnancy rate compared with those received conventional daily subcutaneous rhFSH administration. CONCLUSION Intradermal administration of rhFSH, with a smaller dose of rhFSH and fewer injections, may achieve the goal of a cost-effective and more patient-friendly regimen.

Abstract
OBJECTIVE To determine whether serum human follicle-stimulating hormone (FSH) levels after single subcutaneous dosing of highly purified human menopausal gonadotropins (HP-hMG) in a liquid formulation and a powder formulation are bioequivalent. MATERIALS AND METHODS This was a randomized, two-way, crossover, single-dose, bioequivalence trial comparing Menopur liquid injected by pre-filled pen, with Menopur powder injected by conventional syringe and needle. The primary endpoints were AUCt and Cmax of baseline-adjusted FSH. Pituitary-suppressed, healthy women were administered single subcutaneous injections of 450 IU Menopur liquid (600 IU/0.96 mL) and 450 IU Menopur powder (by 2 subcutaneous injections of 225 IU in 1 mL) in a randomized order. The pharmacokinetic parameters of FSH and human chorionic gonadotropin (hCG) were assessed by non-compartmental methods with adjustment for endogenous pre-dose levels. RESULTS In total, 76 women were randomized, and 56 completed the trial. The mean FSH and hCG serum concentration-time profiles were comparable between the two HP-hMG formulations. The geometric mean ratios and 90% confidence intervals of FSH for HP-hMG liquid versus HP-hMG powder were 1.12 (1.0562 - 1.1889) for AUCt and 1.17 (1.0946 - 1.2490) for Cmax, showing that the two formulations were bioequivalent. The incidence and severity of adverse events were similar between the two preparations, and both preparations were well tolerated. CONCLUSION The 90% CIs for the geometric mean ratios of serum FSH AUCt and Cmax were both within 0.8000 - 1.2500, thus the two formulations are bioequivalent.

Abstract
The uterine first-pass effect occurs when drugs are delivered vaginally. However, the effect of vaginally administered recombinant human follicle-stimulating hormone (rhFSH) on ovarian folliculogenesis and endometrial receptivity is not well established. We aimed to compare the efficacy of rhFSH administered vaginally and abdominally in clinical in vitro fertilization (IVF) treatment, pharmacokinetic study, and animal study. In IVF treatment, the number of oocytes retrieved, endometrial thickness and uterine artery blood perfusion were not different between women who received the rhFSH either vaginally or abdominally. For serum pharmacokinetic parameters, significantly lower Tmax, clearance, and higher AUC and T1/2_elimination of rhFSH were observed in women who received rhFSH vaginally, but urine parameters were not different. Immature female rats that received daily abdominal or vaginal injections (1 IU twice daily for 4 days) or intermittent vaginal injections (4 IU every other day for two doses) of rhFSH had more total follicles than the control group. In addition, the serum progesterone and progesterone receptors in the local endometrium were significantly higher in the groups treated with intermittent abdominal or vaginal injection of rhFSH, compared with those who recieved daily injection. In summary, vaginal administration of rhFSH may provide an alternative treatment regimen in women receiving IVF.

[PMID: 33224104 PMCID: PMC7674484 DOI: 10.3389/fendo.2020.536100] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Accepted: 09/22/2020] [Indexed: 11/13/2022] Open
Abstract
Background When ovarian response to FSH stimulation for IVF/ICSI is unsatisfactory, the FSH dose is often adjusted in the treatment cycles, thereby assuming that hormone status and follicular development were insufficient for optimal stimulation. Objectives To evaluate whether serum delta FSH levels between D6 of gonadotrophin use and basal serum FSH or between D6 of gonadotrophin use and D1 of gonadotrophin use predict ovarian response in IVF/ICSI cycles. Method The participants of this retrospective study were chosen from the Reproductive Medicine, The First Affiliated Hospital of Zhengzhou University between August 2015 and December 2017 (n = 3,109), and during the COS, each participant was given a fixed dose of rFSH in the first 6 days. Delta FSH1: The difference of serum FSH between D6 of gonadotrophin use and basal serum FSH. Delta FSH2: The difference of serum FSH between D6 of gonadotrophin use and D1 of gonadotrophin use. Logistic regression was used to analyze the association between delta FSH1 level and delta FSH2 level and ovarian response. Besides, we also use the tertile statistics to divide the groups. Results Part I: Delta FSH1 levels (mean: 1.41 ± 3.46) in normal responders were higher than delta FSH1 levels (mean: 1.07 ± 23.89) in hyper responders (P = 0.0248). The tertile of delta FSH1 is dif ≤ 0, 0 < dif ≤ 2.25 and dif > 2.25. Compared with the hyper responder, the delta FSH1 (0 < dif ≤ 2.25 and dif > 2.25) in the normal responder has a higher ratio and is statistically significant. Part II: Delta FSH2 levels (mean: 4.90 ± 2.84) in normal responders were similar with delta FSH2 levels (mean: 4.74 ± 2.09) in hyper responders (P = 0.103). The tertile of delta FSH1 is dif ≤ 3.91, 3.91 < dif ≤ 5.69 and dif > 5.69. Compared with the hyper responders, the delta FSH2 (3.91 < dif ≤ 5.69 and dif > 5.69) in the normal responders has a higher ratio and is statistically significant. Conclusions There is a weak relationship between ovarian response and serum delta FSH levels.

Abstract
The first commercially available gonadotropin product was a human chorionic gonadotropin (hCG) extract, followed by animal pituitary gonadotropin extracts. These extracts were effective, leading to the introduction of the two-step protocol, which involved ovarian stimulation using animal gonadotropins followed by ovulation triggering using hCG. However, ovarian response to animal gonadotropins was maintained for only a short period of time due to immune recognition. This prompted the development of human pituitary gonadotropins; however, supply problems, the risk for Creutzfeld-Jakob disease, and the advent of recombinant technology eventually led to the withdrawal of human pituitary gonadotropin from the market. Urinary human menopausal gonadotropin (hMG) preparations were also produced, with subsequent improvements in purification techniques enabling development of products with standardized proportions of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) activity. In 1962 the first reported pregnancy following ovulation stimulation with hMG and ovulation induction with hCG was described, and this product was later established as part of the standard protocol for ART. Improvements in immunopurification techniques enabled the removal of LH from hMG preparations; however, unidentified urinary protein contaminants remained a problem. Subsequently, monoclonal FSH antibodies were used to produce a highly purified FSH preparation containing <0.1 IU of LH activity and <5% unidentified urinary proteins, enabling the formulation of smaller injection volumes that could be administered subcutaneously rather than intramuscularly. Ongoing issues with gonadotropins derived from urine donations, including batch-to-batch variability and a finite donor supply, were overcome by the development of recombinant gonadotropin products. The first recombinant human FSH molecules received marketing approvals in 1995 (follitropin alfa) and 1996 (follitropin beta). These had superior purity and a more homogenous glycosylation pattern compared with urinary or pituitary FSH. Subsequently recombinant versions of LH and hCG have been developed, and biosimilar versions of follitropin alfa have received marketing authorization. More recent developments include a recombinant FSH produced using a human cell line, and a long-acting FSH preparation. These state of the art products are administered subcutaneously via pen injection devices.

Abstract
BACKGROUND AND OBJECTIVE Highly purified human menotrophin and urofollitrophin preparations obtained from human urine via a novel patented purification method have been tested over a timeframe of 14 years in the studies presented in this article. The objective of the studies was to investigate the pharmacokinetics and the pharmacodynamics of follicle-stimulating hormone (FSH) after single subcutaneous and intramuscular doses and multiple subcutaneous doses of the tested preparations in healthy fertile pituitary-suppressed women. DESIGNS We performed five open, randomised, crossover, single-dose bioequivalence and/or bioavailability studies and one open, multiple-dose, pharmacokinetics and pharmacodynamics study. STUDY SUBJECTS AND TREATMENTS The six studies included 121 healthy fertile women taking their usual combined oral contraceptives for 3 months before the study: Study 1: 300 international units (IU) of highly purified menotrophin as single subcutaneous and intramuscular doses. Study 2: 300 IU of highly purified menotrophin (test formulation vs. comparator) as single subcutaneous doses. Study 3: 300 IU of highly purified urofollitrophin (hp-FSH) (test formulation vs. comparator) as single subcutaneous doses. Study 4: 300 IU (2 × 150 IU vs. 4 × 75 IU) of hp-FSH as single subcutaneous doses. Study 5: 225 and 445 IU of hp-FSH as single subcutaneous doses. Study 6: daily 225 IU of hp-FSH as subcutaneous doses for 5 consecutive days. MAIN OUTCOME MEASURES The main outcome measures were the FSH pharmacokinetic parameters, estradiol concentrations, and the number and size of the follicles. RESULTS FSH after single subcutaneous and intramuscular injections of menotrophin or urofollitrophin attained a systemic peak (maximum) concentration (C max) that was on average consistent throughout the first four studies and ranged from 4.98 to 7.50 IU/L. The area under the plasma concentration-time curve (AUC) from administration to the last observed concentration time t (AUCt) ranged from 409.71 to 486.16 IU/L·h and the elimination half-life (t ½) ranged from 39.02 to 53.63 h. After multiple doses of urofollitrophin (225 IU) for 5 days, FSH attained a mean C max of 14.93 ± 2.92 IU/L and had an AUC during the time interval τ between two consecutive doses at steady state (AUCτ) of 322.59 ± 57.92 IU/L·h, which was similar to the mean AUCt after a single subcutaneous dose of 225 IU of urofollitrophin in study 5 (306.82 ± 68.37 IU/L·h). CONCLUSIONS In our studies, the intramuscular and subcutaneous routes of menotrophin were equivalent; both menotrophin and urofollitrophin were bioequivalent to their marketed reference; FSH kinetic parameters following injection of urofollitrophin were dose proportional and independent from the administered concentration; and multiple doses of FSH increased estradiol levels and enhanced growth of follicles with a good dose-response correlation. Local tolerability was excellent throughout the six studies.

Abstract
Background and Objectives FE 999049 is a novel recombinant follicle-stimulating hormone (rFSH) preparation expressed by a human cell line (PER.C6®), in contrast to existing rFSH preparations expressed by Chinese hamster ovary (CHO) cell lines. Since the individual dose of rFSH may be altered depending on the response in women undergoing assisted reproductive technologies, knowledge on the dose-exposure linearity and proportionality is important. The purpose of these studies was to investigate the dose-exposure linearity and proportionality properties of FE 999049 with a comparison between Caucasian and Japanese women. This is the first study in Japanese women regarding pharmacokinetics of rFSH. Methods Forty-eight Caucasian and 31 Japanese healthy women of reproductive age were pituitary down-regulated to suppress endogenous FSH. Following single subcutaneous administration of 37.5, 75, 150, 225, or 450 IU (Steelman–Pohley assay), the serum FSH concentration was followed over 10 days. Results The dose-dependent pharmacokinetic parameters of FE 999049, area under the serum concentration-time curve (AUC) and maximum serum concentration (Cmax), showed dose-exposure linearity and proportionality over 150–450 IU in Caucasian women, the dose interval available for analysis, and 75–450 IU in Japanese women, which was the dose interval investigated. Comparison between Caucasian and Japanese women showed no differences between the populations. The dose-independent parameters were similar over all doses in both populations. FE 999049 was safe and well tolerated at all doses in both populations with few, mostly mild, adverse events. Conclusion The results demonstrate dose-exposure proportionality and a predictable dose-dependent exposure of FE 999049, with no differences in Caucasian and Japanese women of reproductive age.

Abstract
CONTEXT Previous studies suggest that aging in women is associated with a reduction in hypoglycosylated forms of FSH. OBJECTIVE Experiments were performed to determine whether glycosylation of the FSHβ subunit modulates the biological activity of FSH in human granulosa cells. DESIGN AND SETTING Recombinant human FSH (hFSH) derived from GH3 pituitary cells was purified into fractions containing hypoglycosylated hFSH(21/18) and fully glycosylated hFSH(24). The response to FSH glycoforms was evaluated using the well-characterized, FSH-responsive human granulosa cell line, KGN at an academic medical center. INTERVENTIONS Granulosa cells were treated with increasing concentrations of fully- or hypoglycosylated FSH glycoforms for periods up to 48 hours. MAIN OUTCOME MEASURE(S) The main outcomes were indices of cAMP-dependent cell signaling and estrogen and progesterone synthesis. RESULTS We observed that hypoglycosylated FSH(21/18) was significantly more effective than fully glycosylated FSH(24) at stimulating cAMP accumulation, protein kinase A (PKA) activity, and cAMP response element binding protein (CREB) (S133) phosphorylation. FSH(21/18) was also much more effective than hFSH(24) on the stimulation CREB-response element-mediated transcription, expression of aromatase and STAR proteins, and synthesis of estrogen and progesterone. Adenoviral-mediated expression of the endogenous inhibitor of PKA, inhibited FSH(21/18)- and FSH(24)-stimulated CREB phosphorylation, and steroidogenesis. CONCLUSIONS Hypoglycosylated FSH(21/18) has greater bioactivity than fully glycosylated hFSH(24), suggesting that age-dependent decreases in hypoglycosylated hFSH contribute to reduced ovarian responsiveness. Hypoglycosylated FSH may be useful in follicle stimulation protocols for older patients using assisted reproduction technologies.

Abstract
The role of the IVF clinician is to make the ART treatment safe, patient-friendly, cost effective and at the same time offer good and high quality treatment. IVF protocols are a burden for women and are one of the potential reasons why women don’t return for subsequent cycles. Frequent injections may increase stress and also result in high error rates. Simple short treatment regimen with optimal recovery of good quality oocytes results in development of good quality embryos followed by SET in treatment and cryopreservation cycles are a less burden and result in related lesser discontinuation, side effects, treatment cycles in time and are more cost-effective. Development of FSH analogues with longer terminal t1/2 and slower absorption to peak serum levels will increase the efficiency, decrease the side effects and also is easy to administer. This makes it convenient for the patients increasing the compliance. A certain minimum LH concentration is necessary for adequate thecal cell function and subsequent oestradiol synthesis in the granulosa cells. Adjuvant r-HLH gives clinician's precise control over the dose of LH bioactivity administered to target the therapeutic window. New parenteral, transdermal, inhaled and oral fertility drugs and regimens are currently under research and development with the objective to further simplify treatment for ART.

Abstract
OBJECTIVE Evaluation of the pharmacokinetics and safety of s.c. hydrocortisone injection for use in adrenal emergency. DESIGN Single-center, open-label, sequence-randomized, crossover study in a tertiary care center. PATIENTS AND METHODS Twelve patients with chronic Addison's disease. Comparison of hydrocortisone pharmacokinetics after s.c. and i.m. injection (100 mg) and after s.c. administration of sodium chloride (0.9%) respectively at three different visits. MAIN OUTCOME MEASURE maximum serum cortisol (Cmax), time to Cmax (tmax), and time to serum cortisol >36 μg/dl (tserum cortisol >36 μg/dl) after s.c. administration compared with i.m. administration, safety, and patient preference. RESULTS Serum cortisol increased rapidly and substantially after both i.m. and s.c. injections (Cmax: 110±29 vs 97±28 μg/dl, P=0.27, tmax: 66±51 vs 91±34 min, P=0.17, and tserum cortisol >36 μg/dl: 11±5 vs 22±11 min, P=0.004 respectively). Both i.m. and s.c. injections were well tolerated. Eleven (91.7%) patients preferred s.c. injection, whereas one patient did not have any preference. CONCLUSIONS S.c. administration of 100 mg hydrocortisone shows excellent pharmacokinetics for emergency use with only a short delay in cortisol increase compared with i.m. injection. It has a good safety profile and is preferred by patients over i.m. injection.

Abstract
Corifollitropin alfa is a synthetic recombinant follicle-stimulating hormone (rFSH) molecule containing a hybrid beta subunit, which provides a plasma half-life of ∼65 hours while maintaining its pharmocodynamic activity. A single injection of corifollitropin alfa can replace daily FSH injections for the first week of ovarian stimulation for in vitro fertilization. Stimulation can be continued with daily FSH injections if the need arises. To date, more than 2500 anticipated normoresponder women have participated in clinical trials with corifollitropin alfa. It is noteworthy that one-third of women did not require additional gonadotropin injections and reached human chorionic gonadotropin criterion on day 8. The optimal corifollitropin dose has been calculated to be 100 μg for women with a body weight ≤60 kg and 150 μg for women with a body weight >60 kg, respectively. Combination of corifollitropin with daily gonadotropin-releasing hormone antagonist injections starting on stimulation day 5 seems to yield similar or significantly higher numbers of oocytes and good quality embryos, as well as similar ongoing pregnancy rates compared with women stimulated with daily rFSH injections. Stimulation characteristics, embryology, and clinical outcomes seem consistent with repeated corifollitropin-stimulated assisted reproductive technologies cycles. Multiple pregnancy or ovarian hyperstimulation syndrome rates with corifollitropin were not increased over daily FSH regimen. The corifollitropin alfa molecule does not seem to be immunogenic and does not induce neutralizing antibody formation. Drug hypersensitivity and injection-site reactions are not increased. Incidence and nature of adverse events and serious adverse events are similar to daily FSH injections. Current trials do not provide information regarding use of corifollitropin alfa in anticipated hyper- and poor responders to gonadotropin stimulation. Although corifollitropin alfa is unlikely to be teratogenic, at the moment data on congenital malformations is missing.

Abstract
BACKGROUND Multifollicular ovarian stimulation (MOS) is widely used in IVF and the compliance to treatment is deeply influenced by the tolerability of the medication(s) used and by the ease of self-administration. This prospective, controlled, randomised, parallel group open label, multicenter, phase III, equivalence study has been aimed to compare the clinical effectiveness (in terms of oocytes obtained) and tolerability of subcutaneous (s.c.) self-administered versus classical intramuscular (i.m.) injections of Merional, a new highly-purified hMG preparation. METHODS A total of 168 normogonadotropic women undergoing IVF were enrolled. Among them, 160 achieved pituitary suppression with a GnRH-agonist long protocol and were randomised to MOS treatment with Merional s.c. or i.m. They started MOS with a standard hMG dose between 150-300 IU, depending upon patient's age, and underwent a standard IVF procedure. RESULTS No statistically significant difference in the mean number of collected oocytes (primary endpoint) was observed between the two study subgroups (7.46, SD 4.24 vs. 7.86, SD 4.28 in the s.c. and i.m. subgroups, respectively). As concerns the secondary outcomes, both the pregnancy and the clinical pregnancy rates were comparable between subgroups. The incidence of adverse events was similar in the two groups (2.4% vs. 3.7%, respectively). Pain at injection site was reported only the i.m. group (13.9% of patients). CONCLUSION Merional may be used by s.c. injections in IVF with an effectiveness in terms of retrieved oocytes that is equivalent to the one obtained with i.m administration and with a better local tolerability. With the limitations due to the sample size af this study, s.c. and i.m. administration routes seem to have the same overall safety.

Abstract
Aim: The aim of the present study was to establish a standard protocol for ovarian stimulation with gonadotropin-releasing hormone analog (GnRH-a) long protocol using recombinant-follicle stimulating hormone (rec-FSH) preparations for assisted reproductive technology (ART) treatment. Methods: In 86 patients who underwent ovarian stimulation with GnRH-a long protocol for ART treatment, 53 were stimulated by rec-FSH preparations (rec-FSH group) and the others were stimulated by urinary-hMG (u-hMG group) preparations. The subjects were randomly assigned to either of these preparations. Hormonal profiles, total doses of gonadotropins, duration of stimulation and ART results were compared in both groups. Results: The duration of stimulation was similar in both groups (9.2 ± 0.3 days and 9.2 ± 0.2 days, respectively). The total doses of gonadotropin in the rec-FSH group (1505.3 ± 29.2 IU) was significantly lower than those in the u-hMG group (2130.3 ± 54.6 IU, P < 0.0001). The FSH and LH values on the day of human chorionic gonadotropin (hCG) administration in the rec-FSH group were significantly lower than those in the u-hMG group. Pregnancy rates were 31.3% in the rec-FSH group and 33.3% in the u-hMG group, respectively. Conclusions: The present study showed that rec-FSH preparations were more potent than conventional u-hMG preparations and the protocol of the present study with rec-FSH was a new ovarian stimulation protocol with GnRH-a long protocol.

Abstract
OBJECTIVE To carefully examine the features of controlled ovarian stimulation performed with recombinant FSH-alpha or hMG. DESIGN Controlled, prospective, randomized comparison of fixed gonadotropin regimens. SETTING Academic research institution. PATIENT(S) Fifty infertile patients who were candidates for IUI. INTERVENTION(S) Patients were randomized to receive a fixed regimen of recombinant FSH-alpha (150 IU/day, 25 patients) or hMG (150 IU/day, 25 patients), after GnRH-agonist suppression (long regimen). MAIN OUTCOME MEASURES Daily measurements of serum LH, immunoreactive FSH, hCG, E(2), P, and T. Transvaginal pelvic ultrasound every 2 days. Pregnancy and abortion rates. Cost of medications. Two recombinant FSH-alpha-treated patients did not respond. Despite matched daily FSH dose, duration of treatment (hMG 10.8 +/- 0.4 vs. recombinant FSH-alpha 12.4 +/- 0.5 days), gonadotropin dose (21.7 +/- 0.8 vs. 25.3 +/- 1.3 ampoules), gonadotropin cost (288 +/- 10 vs. 1,299 +/- 66 /cycle), serum P levels, and small preovulatory follicle number were significantly lower, and LH, hCG, immunoreactive FSH levels, and larger follicles on day 8 were significantly higher in hMG-treated patients. The pregnancy, abortion, and twin pregnancy rates did not differ. CONCLUSION The hMG administration was associated with: [1]. increased serum LH activity and immunoreactive FSH levels during treatment; [2]. reduced signs of premature luteinization; [3]. differential modulation of folliculogenesis; [4]. lower treatment duration, gonadotropin dose, and cost; and [5]. clinical outcome comparable to recombinant FSH-alpha.

Abstract
This article reviews the past, present, and future of gonadotrophin therapy, including purification of gonadotrophins from animal or human urine sources and production of gonadotrophins through recombinant technology. With the advent of recombinant DNA methodologies combined with site-directed mutagenesis, a variety of structural modifications becomes possible.
