This method was developed to cope with variability of production batch quality. The bioassay, however, presents some limitations, and differences in clinical responses when using different batches of urine-derived gonadotrophins have been reported. The production of human FSH by recombinant technology now allows the use of advanced physicochemical methods for quantifying FSH, which can be measured in µg of FSH proteins (in mass). The study reported here was designed and conducted to assess the clinical relevance of this new method for quantifying therapeutic preparation of FSH. Four bulk lots of recombinant human FSH (r-hfsh) were used to prepare batches filled by IU (FbIU) and four batches filled by mass (FbM). These eight batches were compared in a double-blind, randomized study in patients undergoing assisted reproductive technology. One hundred and thirty-one patients were enrolled in this study and met protocol criteria (66 in the FbM group and 65 in the FbIU group). The starting dose of recombinant human FSH (r-hfsh) was either 150 IU or 11 µg/day. Both preparations induced multiple follicular development and all patients underwent oocyte retrieval. The number of follicles 11 mm was and 14.91, serum oestradiol concentration on day of human chorionic gonadotrophin (HCG) administration was 6524 and 6350 pmol/l, number of oocytes retrieved was and 11.28, number of two-pronuclear (2 PN) oocytes was 5.2 and 5.00, number of viable embryos (replaced or cryopreserved) was 4.15 and 3.72, and clinical pregnancy rate was 30.3 and 26.2% respectively in the FbM and FbIU groups. Overall, the patients response consistency was found to be superior with FbM (P = 0.039), and in particular for clinical pregnancy rates (P < 0.001). This new method for quantifying r-hfsh delivers an improved consistency in clinical outcome. Keywords: assisted reproduction treatment, bioassay, FSH, gonadotrophins, recombinant technology 185
2 186 Introduction FSH is a complex heterodimeric glycoprotein secreted by the pituitary gland. Therapeutic preparations of human FSH are used broadly to stimulate ovarian follicle growth in infertile women, and spermatogenesis in hypogonadotrophic hypogonadal men. Until 1995, all human FSH pharmaceutical preparations were extracted from post-menopausal urine i.e. Menotropin or human menopausal gonadotrophin (HMG) and urofollitropin or u-hfsh. Marked heterogeneity with respect to bioactivity, immunoreactivity, LH content and isohormone profiles has been reported between different commercial urinary gonadotrophin preparations (Harlin et al., 1986; Rodgers et al., 1995) and, more importantly, between batches of the same preparation (Cook et al., 1988; Stone et al., 1989; Braileanu et al., 1998). Variability in the quality of the gonadotrophin preparations has been shown to contribute to differences in patient response (Stone et al., 1989; Rector et al., 1993). In order to overcome the variability of urine-derived products, FSH activity in batches of gonadotrophin preparations is assessed by the Steelman and Pohley rat in-vivo bioassay (Steelman and Pohley, 1953). Briefly, each production batch is tested in rats in order to quantify its FSH activity content. The end-point of the test is the rat ovarian weight gain. Measuring rat ovarian weight has inherent limitations, hence the European Pharmacopoeia defines an activity range within which an FSH batch is acceptable for clinical use. The practical consequence is that a labelled 75 IU FSH ampoule may theoretically contain anything between 48 and 117 IU FSH (finished product FSH activity, fiducial limits) (European Pharmacopoeia). Over the last 30 years, attempts to replace the cumbersome invivo bioassay by an immunoassay or an in-vitro bioassay have been undertaken (Rose et al., 2000). However, because the biological activity of FSH is heavily determined by its glycosylation, which defines its pharmacokinetic characteristics as well as its activity at the receptor level (Galway et al., 1990; Chappel, 1995; Vitt et al., 1998; Creus et al., 2001), these attempts have failed to provide a reliable predictor of FSH therapeutic activity (Rose et al., 2000). Recombinant DNA technology allows the in-vitro production of human FSH (r-hfhs) with very high purity and consistent quality (Recombinant Human FSH Development Group, 1998). Recombinant FSH has been demonstrated to be the most effective agent yet developed for stimulating human follicular development (Daya et al., 2001). However, r-hfsh release specifications still include the Steelman and Pohley bioassay. Because of its high purity, each production batch of r-hfsh (Gonal-F ; Serono, Aubonne, Switzerland) has been routinely characterized and controlled using physicochemical techniques, including size exclusion high performance liquid chromatography (SE-HPLC), isoelectric focusing (IEF) (Siebold, 1996) and glycan mapping (Gervais et al., 2003). The first method allows assessment of the integrity of FSH molecules as well as quantifying the amount of FSH, while the last two allow the characterization of FSH glycoforms present in the preparation. This approach is consistent with the current trend for therapeutic proteins in finding alternative approaches to biological assay to assess their activity (Jeffcoate, 1994; Mulders et al., 1997). The result of the characterization of more than 100 batches of this r-hfsh preparation has demonstrated that for this product there is a consistent glycosylation profile in the different production batches, and that there is a constant relationship between the FSH mass (µg) and its biological activity (Driebergen et al., 2002). Because measuring FSH µg by SE- HPLC is more precise, it has been postulated that substituting this assay for the bioassay to calibrate each batch of r-hfsh would deliver more consistent FSH activity. This clinical trial has been designed and conducted to assess the clinical relevance of the improved manufacturing process. Materials and methods This was a multicentre, double-blind, randomized, parallel group study to compare the safety and efficacy of r-hfsh preparations (Gonal-F ) filled and released by µg (FbM) and filled and released by IU (FbIU) in stimulating multiple follicular development prior to in-vitro fertilization (IVF). The study was conducted in three clinical centres according to Good Clinical Practice (GCP) standards, including patient s written informed prior to enrolment in the study. The protocol was approved by each of the three centre s Institutional Review Board or Ethics Committee. Study population Patients admitted to the study were infertile women desiring pregnancy and justifying assisted reproductive techniques (IVF, ICSI), provided that they conformed to the following eligibility criteria: (i) infertility justifying assisted reproduction treatment, (ii) a male partner with semen analysis obtained within 6 months prior to beginning gonadotrophin (GnRH)-agonist therapy with > motile spermatozoa (motility grade A or B) per ml in the whole ejaculate and an oocyte fertilization rate 20% during any previous assisted reproduction treatment attempt, (iii) aged years (inclusive), a spontaneous ovulatory menstrual cycle of days, (iv) early follicular phase (day 2 4) serum FSH <12 IU/l, serum LH <13.5 IU/l, serum prolactin <800 miu/l, serum oestradiol <75 pg/ml, (v) presence of both ovaries, (vi) a body mass index (BMI) <30, (vii) not more than three previous consecutive assisted reproduction treatment cycles without a clinical pregnancy, (viii) no previous assisted reproduction treatment cycle indicating a poor response to gonadotrophin stimulation, (ix) in the early follicular phase, a baseline endovaginal ultrasound scan showing no more than 13 follicles 4 mm and 8 mm on the largest section through one ovary. The primary objective of this study was to confirm the equivalence of rfsh filled and released by mass or by bioactivity in stimulating multiple follicular development in women undergoing IVF and embryo transfer. The set of patients to be used for all statistical analyses was the per protocol dataset. The number of patients in this study was determined on practical and statistical grounds. A maximum difference of 2 in the number of follicles 11 mm was considered as a relevant efficacy concern. Using a one-sided level of significance of 0.05 and assuming that the common standard deviation is 5.4, the power to accept the equivalence between the two treatments was 70% for 65 evaluable patients per group.
3 Randomization When a patient had signed the informed consent form, was found to be eligible for the study and pituitary down-regulation with GnRH-agonist was confirmed, she was allocated a unique patient identification number in sequential, chronological order. This identification number assigned the patient in a blinded fashion to one of the eight batches of rfsh filled and released by either mass (FbM) or bioactivity (FbIU) according to a computer generated randomization list. The randomization was stratified by treatment and by centre, so that all centres received r-hfsh from the eight batches. Study medication and administration regimen Eight batches of r-hfsh were used in the study. These batches were obtained from four different lots of r-hfsh, with each lot used to produce one batch filled and released by µg and one batch filled and released by bioactivity (Figure 1). All r-hfsh lots were produced at the same production site (Laboratoires Serono, Aubonne, Switzerland). All batches were produced at the same production site (Serono Pharma Bari, SPB, Italy). The finished product was supplied in ampoules delivering either 75 IU of r-hfsh or its mass equivalent, i.e. 5.5 µg FSH, 30 mg sucrose and phosphate buffer in a lyophilized form. Treatment with rfsh began after at least 10 days of GnRHagonist therapy when pituitary desensitization was achieved, and was administered subcutaneously once daily in the abdominal wall. The starting fixed dose was 150 IU FSH/day (i.e. two ampoules/day) for 5 days (inclusive). The dose could be adapted as of day 6 of stimulation, according to the ovarian response monitored by ultrasound and serum oestradiol concentrations. The maximum dose allowed was 450 IUFSH/day (i.e. six ampoules/day). In order to achieve final follicular maturation before oocyte retrieval, urinary human chorionic gonadotrophin (u-hcg) was administered subcutaneously or intramuscularly at a dose of up to 10,000 IU. Oocytes were retrieved h after u-hcg administration and fertilized in vitro. Not more than three of the resulting embryos were replaced. Natural progesterone was administered vaginally, every day starting after oocyte retrieval and continuing either up to menstruation, or if the patient became pregnant, for at least the first 3 weeks of pregnancy. The patient was followed up and the treatment outcome (pregnancy or menstruation) was recorded. If, at any time, a clinician suspected that a patient might be at risk of ovarian hyperstimulation syndrome, the dosage of r- hfsh was reduced or administration discontinued. Results Patient disposition and demographics A total of 131 patients were enrolled, randomized to r-hfsh treatment and included in the per protocol population. Sixty-six patients were allocated to r-hfsh FbM and 65 to r-hfsh FbIU. Treatment outcomes were as follows: all patients qualified for and received HCG and underwent oocyte retrieval, and 63 and 61 had at least one embryo transferred in the FbM and FbIU group respectively. In terms of demographic characteristics, the two groups were well balanced. Patients ages were 30.8 ± 4.0 and 31.4 ± 3.5; BMI was 23.1 ± 3.2 and 22.5 ± 3.1; the proportion of non-smoker was 72.7 and 72.3%; the proportion of primary infertility was 60.6 and 56.9%; duration of infertility was 3.7 ± 2.9 and 3.7 ± 2.5 years; mean cycle duration was 28.7 ± 1.5 and 29.0 ± 1.7 days, the proportion of patients without previous assisted reproduction treatment was 74.2 and 73.8%; baseline serum FSH was 7.4 ± 1.4 and 7.4 ± 1.7 IU/l; baseline serum LH was 3.8 ± 1.3 and 3.8 ± 1.2 IU/l; and number of follicle between 4 and 8 mm in diameter in both ovaries was 7.3 ± 4.0 and 8.5 ± 5.2 in the FbM and the IU groups respectively. In addition, no difference was recorded in baseline sperm characteristics between the treatment group partners. The duration of GnRH agonist administration (from start to HCG) was comparable between the two groups, with 28.3 ± 6.5 days and 28.9 ± 6.5 days for the FbM and the FbIU groups respectively. Figure 1.

Both preparations achieved significant ovarian stimulation, resulting in a large number of embryos and a clinical pregnancy rate close to 30% per treated cycle. Variability of the ovarian response to different batches of r- hfsh was compared for all efficacy parameters. Figure 2 shows the mean number of oocytes retrieved in patients treated with the four batches of FbM and the corresponding four batches of FbIU. Figure 3 shows similar presentation for pregnancy rates. For both parameters, the r-hfsh FbM batches appear to deliver a more consistent therapeutic effect. This consistency was quantified and tested comparing the difference between the highest and the lowest mean value in each treatment group for efficacy parameters (Table 2). For the majority of the efficacy parameters, FbM performed more consistently than FbIU, as illustrated by a smaller difference between the mean results obtained in each four patient subgroups. Overall, as well as for clinical pregnancy rates, FbM consistency was found to be statistically superior to FbIU (P = and respectively). The safety assessment showed the expected adverse events associated with ovarian stimulation and assisted reproduction technology, with the most frequently reported being headaches and abdominal pain and discomfort. Six cases of ovarian hyperstimulation syndrome (OHSS) (four mild and two moderate) were reported in the FbIU group and four (three mild and one severe) were reported in the FbM group (P = 0.531) (Table 2). Discussion The purity of human FSH produced by recombinant DNA technology has made possible the use of state-of-the-art methods for characterizing the integrity of FSH, the FSH glycosylation pattern and for quantifying the FSH content of individual production batches. Extensive experience with rfsh production has revealed a very consistent pattern of integrity and glycosylation overtime (Driebergen et al., 2002; Gervais et al., 2003). This has led to the conclusion that replacing the standard bioassay, which was developed to cope with the variability of urine-derived FSH preparations, by an SE-HPLC 188 a Figure 2.

This clinical study assessed the possible clinical benefit of applying this new calibration method by comparing the clinical response to four batches calibrated in µg (FbM) with four batches calibrated in IU (FbIU). The study results support the selected conversion factor, as illustrated by the clinical outcome in the two treatment groups. More important for clinicians are the results regarding consistency of the clinical response between batches. It is well established that patient s responses to ovarian stimulation treatment are variable. Parameters contributing to this variability are numerous and include patient s age, ovarian reserve, pre-treatment with GnRH analogues and oral contraceptive pill, and polycystic ovaries. The levels of ovarian response directly and indirectly impact on the clinical pregnancy rates, since the latter is directly related to the number of embryos obtained in vitro and to the number of embryos replaced, both of which are strong prognostic factors for conception (Templeton and Morris, 1998). Adding additional variability in this context is unlikely to be beneficial. This study shows that in a homogeneous population of patients receiving assisted reproduction treatment, the improved manufacturing process was associated with an improvement in the consistency of the ovarian response, including significantly improved consistency in the clinical pregnancy rate between batches of gonadotrophin. The variability between clinical outcome resulting from treatment with different FbM batches was reduced, indicating that in a well-defined patient population the quality of the gonadotrophin preparation may have a predominant role in the consistency of clinical response. This study did not include a urinary gonadotrophin arm. However, published data indicate that a larger variation may be expected in clinical response when using different batches of urinederived gonadotrophins. In a retrospective study, comparing nine batches of HMG, Stone et al. reported a mean number of large follicles at OPU ranging between 6.4 ± 0.8 and 10.4 ± 1.4 and a pregnancy rate ranging between 0 and 21% (Stone et al., 1989). 189
6 190 In conclusion, the consistent quality of the recombinant DNA technology manufacturing process for human FSH has allowed for the first time, the delivery of FSH based on µg of protein. This new method results in further improvement in r-hfsh preparations by delivering increased consistency in clinical outcome.
