BACKGROUND / RATIONALE
FE 999049 is a human recombinant follicle-stimulating hormone (rFSH) belonging to the 
pharmaceutical class of gonadotropins. It is intended for the following indication: “Controlled 
ovarian stimulation for the development of multiple follicles in women undergoing assisted 
reproductive technologies (ART) such as an in vitro fertilisation (IVF) or intracytoplasmic sperm 
injection (ICSI) cycle”. FE 999049 will be delivered as a solution for injection for subcutaneous 
self-administration by an injection pen.
FE 999049 is expressed from a host cell line of human fetal retinal origin (PER.C6®). The PER.C6®
cell line is well-characterised, and bio-testing of the master cell bank has demonstrated safety and 
consistency. FE 999049 is a glycoprotein which is composed of two non-covalently bound 
polypeptide chains, denoted alfa (α) and beta (β). The α-subunit contains 92 amino acid residues
with 5 intrachain-disulphide bonds. The β-subunit contains 111 amino acid residues with 
6 intrachain-disulphide bonds. Each subunit is N-glycosylated at two positions, and about 40% of 
the total mass is carbohydrates.
There are no commercially available rFSH products derived from human cell lines, but Ferring has 
recently submitted a Marketing Authorisation Application to the European Medicines Agency 
(EMA) for FE 999049 (October 2015) and received positive opinion from the Committee for 
Medicinal Products for Human Use (October 2016). Currently-approved rFSH products for the 
proposed indication, such as follitropin alfa (GONAL-F, Merck Serono) and follitropin beta 
(PUREGON, MSD), are derived from a Chinese hamster ovary (CHO) cell line. The amino acid 
sequence of FE 999049 is identical to the endogenous human FSH sequence and to that in existing 
CHO-derived rFSH products. Manufacturing from different cell systems leads to glycosylation 
heterogeneity between rFSH preparations. The glycosylation profile of recombinant proteins is 
dependent on the expressing cell line and the cell culture conditions. Differences in glycosylation

profile, sialic acid pattern and isoform profile, have been documented between FE 999049 and
existing rFSH products from a CHO cell line. Comparison between the FE 999049 and the 
GONAL-F and PUREGON profiles indicate differences in acidity and carbohydrate side chains. As 
CHO cells lack enzymatic functions to construct more complex carbohydrate structures found in 
humans, the glycosylation profile of FE 999049 is more complex. In addition, RE 999049 contains 
both α2,3 and α2,6 sialylation patterns, while CHO-derived rFSH products exclusively carry 
2,3 linked sialic acid; this difference further contributes to the observed differences in glycosylation 
profiles between FE 999049 and CHO-derived rFSH products.
Before the current trial, Ferring has completed four phase 1 trials, two phase 2 dose-response trials
(one conducted in EU and one in Japan) and two phase 3 trials as part of the clinical development 
programme for FE 999049. A total of 1,927 subjects have been included in the completed clinical 
trials, of whom 1,112 subjects were exposed to FE 999049.
The two phase 2 trials were randomised, controlled, assessor-blind, multi-centre dose-response 
trials in which randomisation was stratified according to the subject’s anti-Müllerian hormone 
(AMH) level at screening. In both trials, a statistically significant dose-response relationship for 
FE 999049 with respect to the number of oocytes retrieved was observed for the overall population 
and for each AMH strata. Furthermore, the dose-response profile observed in Japanese and 
European subjects was similar. An individualised FE 999049 dosing regimen based on subject’s 
AMH level and body weight was designed by modelling and simulation and prospectively tested in 
the phase 3 trials.
During the phase 3 trials, 665 IVF/ICSI subjects were treated with FE 999049 in 1,012 treatment 
cycles. The two phase 3 trials supported the efficacy and safety of FE 999049 in the proposed 
indication. ESTHER-1 (trial 000004, Evidence-based Stimulation Trial with Human rFSH in 
Europe and Rest of World, ESTHER) was an efficacy trial designed to demonstrate non-inferiority 
of FE 999049 versus an approved recombinant FSH preparation with ongoing pregnancy rate and 
ongoing implantation rate as co-primary endpoints (as agreed with the EMA during Scientific 
Advice) and also to prospectively evaluate the outcome of the stratified medicine approach with the 
individualised FE 999049 dosing regimen based on the AMH level (measured by Elecsys® AMH 
Immunoassay, Roche Diagnostics) and body weight. ESTHER-2 (trial 000071) was a safety 
immunogenicity trial with up to two repeated treatment cycles in subjects who did not achieve an
ongoing pregnancy in ESTHER-1. Both trials have been completed with respect to their 
intervention part.
The ESTHER-1 trial demonstrated non-inferiority of FE 999049 to GONAL-F for the two co-
primary endpoints, ongoing pregnancy rate and ongoing implantation rate, for both the per-protocol 
(PP) and modified intention-to-treat (mITT) populations. Across treatment groups and analysis 
populations, the ongoing pregnancy rate was in the range 31-33% and the ongoing implantation rate 
in the range 35-37%. 
The AMH dosing regimen for FE 999049 in controlled ovarian stimulation cycles led to a 
statistically significantly lower proportion of subjects with extreme ovarian response (<4 or ≥15 
oocytes retrieved or <4 or ≥20 oocytes retrieved) compared to the GONAL-F group, when adjusted 
for AMH. Furthermore, the value of the individualised FE 999049 dosing regimen was reflected in 
statistically significant and clinically relevant reductions in ovarian hyperstimulation syndrome 
(OHSS) risk management compared to GONAL-F. Overall, the incidence of preventive 
interventions for early OHSS among subjects treated with FE 999049 was half of that observed 
with GONAL-F, which was a statistically significant reduction. The combined incidence of early

OHSS (all and those of moderate/severe grade) and/or preventive interventions for early OHSS was 
also statistically significantly reduced with FE 999049 in comparison to GONAL-F. Overall, there 
was a statistically significantly lower incidence of total OHSS and/or preventive interventions for 
early OHSS, and of total moderate/severe OHSS and/or preventive interventions for early OHSS 
with FE 999049 compared to GONAL-F.
A design similar to the phase 3 trial ESTHER-1 is being proposed for the present trial to be 
conducted in mainland China and other Asian countries and regions, with some modifications 
according to local practice. The primary objective of this trial is to demonstrate non-inferiority of 
FE 999049 compared with GONAL-F with respect to ongoing pregnancy rate in women 
undergoing controlled ovarian stimulation.

METHODOLOGY
This will be a randomised, controlled, assessor-blind, parallel groups, multicentre, Pan-Asian non-
inferiority trial comparing the efficacy and safety of two rFSH preparations, FE 999049 and 
follitropin alfa (GONAL-F), in first cycle subjects aged 20-40 years undergoing controlled ovarian 
stimulation for IVF/ICSI following a gonadotropin-releasing hormone (GnRH) antagonist protocol. 
The trial has been designed to demonstrate non-inferiority of FE 999049, a human cell line-derived 
rFSH preparation, versus an approved CHO-derived rFSH preparation, i.e. GONAL-F, with 
ongoing pregnancy rate as the primary endpoint. Secondary endpoints include pharmacokinetic 
profile of FE 999049, pharmacodynamic parameters of FSH action as well as efficacy and safety 
parameters related to controlled ovarian stimulation. The assessor-blind design ensures that the 
investigators and other assessors such as embryologists and central laboratory personnel are blinded 
to individual treatment allocation. The sponsor will break the blind when all subjects have 
completed the end-of-trial visit, in order to evaluate efficacy and safety up to the ongoing 
pregnancy visit.
Subjects will be screened within 90 days prior to randomisation for compliance with the inclusion 
and exclusion criteria. On day 2-3 of the menstrual cycle, subjects will be randomised in a 1:1 ratio 
to treatment with either FE 999049 or GONAL-F, and stimulation will be initiated. Randomisation 
will be stratified by centre and according to age (<35, 35-37 and 38-40 years). Subjects randomised 
to FE 999049 will have their individual dose determined on the basis of their AMH level at 
screening and their body weight at randomisation. The daily FE 999049 dose will be fixed
throughout the stimulation period. For subjects with low AMH (<15 pmol/L) the daily FE 999049 
dose is 12 μg, irrespective of body weight. For subjects with high AMH (≥15 pmol/L) the daily 
FE 999049 dose is on a continuous scale ranging from 0.19 to 0.10 μg/kg, i.e. dependent on actual 
AMH and body weight (note: the minimum and maximum allowed daily doses are 6 µg and 12 µg, 
respectively). Subjects can be treated with FE 999049 for a maximum of 20 days, and coasting is 
not allowed. For subjects randomised to GONAL-F, the dosing regimen is within labelling. The 
starting daily dose of GONAL-F is 150 IU and fixed for the first five stimulation days after which it 
may be adjusted by 75 IU per day based on the individual response. The maximum daily GONAL-
F dose allowed is 450 IU. Subjects can be treated with GONAL-F for a maximum of 20 days, and 
coasting is not allowed. 
During stimulation, subjects will be monitored by transvaginal ultrasound on stimulation day 1 and 
6 and hereafter at least every second day. When the leading follicle reaches ≥15 mm, visits must be 
performed daily. To prevent a premature LH surge, a GnRH antagonist will be initiated on 
stimulation day 6 and continued throughout the stimulation period. Triggering of final follicular 
maturation will be done as soon as ≥3 follicles with a diameter ≥17 mm are observed. If there are 
<25 follicles with a diameter ≥12 mm, human chorionic gonadotropin (hCG) will be administered. 
If there are 25-35 follicles with a diameter ≥12 mm, a GnRH agonist can be administered or the 
cycle can be cancelled. In case of excessive follicular development, defined as >35 follicles with a 
diameter ≥12 mm, the cycle is to be cancelled. If it is judged by the investigator that ≥3 follicles 
with a diameter ≥17 mm cannot be reached, but 1 or 2 follicles with a diameter ≥17 mm are 
observed, the cycle may either be cancelled due to poor follicular development or triggering of final 
follicular maturation is to be induced, as judged by the investigator.

Oocyte retrieval will take place 36h (±2h) after triggering of final follicular maturation and the 
oocytes can be inseminated by IVF or ICSI. Rescue ICSI is not allowed. Fertilisation and embryo 
development will be assessed from oocyte retrieval to the day of transfer. For subjects who 
underwent triggering of final follicular maturation with hCG, transfer is performed on day 3
(embryo stage) after oocyte retrieval. Subjects <35 years at randomisation will have single embryo 
transfer if a good-quality embryo is available; otherwise, double embryo transfer will be performed 
(and single transfer if two embryos are not available). Subjects ≥35 years at randomisation will 
have double embryo transfer (and single transfer if two embryos are not available). Remaining 
embryos may be cryopreserved in accordance with local guidelines and/or regulations. For subjects 
who underwent triggering of final follicular maturation with GnRH agonist, no transfer will take 
place in the current fresh cycle and the embryos available will be cryopreserved on day 3, 5 or 6, 
according to local practice. All cryopreserved embryos can be used by the subject after completion 
of the trial, in accordance with local guidelines and/or regulations. 
Vaginal progesterone will be provided for luteal phase support from the day of oocyte retrieval or 
the day after and at least until clinical pregnancy. Thereafter the investigator may decide to 
continue up to the ongoing pregnancy visit, according to local practice. Progesterone administration 
should not continue if menses, negative βhCG or pregnancy loss occurs. A serum βhCG test will be
performed 13-15 days after transfer, clinical pregnancy will be confirmed by transvaginal 
ultrasound 5-6 weeks after transfer, and ongoing pregnancy will be confirmed by transvaginal or 
abdominal ultrasound 10-11 weeks after transfer.
Blood samples will be collected throughout the trial for the purpose of evaluating the endocrine 
profile, clinical chemistry and haematology parameters as well as anti-FSH antibodies. Endocrine 
parameters are assessed at screening, stimulation day 1, stimulation day 6 and end-of-stimulation, 
furthermore FSH is also assessed at oocyte retrieval. Clinical chemistry and haematology 
parameters are assessed at screening, stimulation day 1, end-of-stimulation and end-of-trial. Anti-
FSH antibodies are collected at four occasions. The first blood sample is taken at the screening visit 
and is exclusively used as back-up samples for the anti-drug antibody assay development. The 
subsequent three samples are used for analysis of anti-FSH antibodies in the individual subjects in 
the trial, and are taken prior to dosing on stimulation day 1 and at two occasions post-dosing: 5-10 
days after the last FE 999049 or GONAL-F dose (it may coincide with the transfer visit) and 19-28 
days after the last FE 999049 or GONAL-F dose (it may coincide with the βhCG test visit). 
Subjects with a treatment-induced anti-FSH antibody response will be followed until the response 
has become negative or returned to the pre-dosing level, with a maximum follow-up period of one 
year. 
Local tolerability of FE 999049 and GONAL-F following subcutaneous administration will be 
assessed by the subject three times daily: immediately, 30 minutes and 24 hours after each 
injection. The assessment of injection site reactions will be made throughout the stimulation period 
and recorded by the subjects in a diary. 
Post-Trial Activities
Post-trial activities cover pregnancy and neonatal health follow-up. All subjects with an ongoing 
pregnancy will be followed till delivery to gather information on live birth rate. Furthermore, data 
will be gathered on neonatal health, including any congenital anomalies, at birth and at 4 weeks 
after birth. These data will be reported separately.

NUMBER OF SUBJECTS
It is planned to randomise 1,000 subjects from 15-30 sites in mainland China and other Asian 
countries and regions. Of the 1,000 subjects it is expected that 740 subjects will be recruited in 
mainland China (i.e. possessing a Chinese identification card and having native Chinese parents)
and the rest from other Asian countries and regions, potentially Taiwan, South Korea and Vietnam. 
It is estimated that approximately 1,200 subjects should be screened to achieve 1,000 subjects 
eligible for randomisation.

DURATION OF TREATMENT
The maximum period of exposure to FE 999049 or GONAL-F is 20 days.
STATISTICAL METHODS
The primary objective of this trial is to demonstrate non-inferiority of FE 999049 compared with 
GONAL-F with respect to ongoing pregnancy rate in women undergoing controlled ovarian 
stimulation. Ongoing pregnancy is defined as at least one intrauterine viable fetus 10-11 weeks 
after transfer. The non-inferiority limit for the difference between treatments (FE 999049 versus 
GONAL-F) is -10.0% (absolute) for the primary endpoint. 
The trial is designed to have 90% power of achieving the primary objective for the overall trial 
population and to have 80% power in the mainland Chinese population. Assuming an ongoing 
pregnancy rate of 32.2% in both treatment groups, a total of 918 subjects are needed in the PP 
analysis set. To account for major protocol deviations a total of 1,000 subjects should be 
randomised. To secure that consistency can be established between the results from the overall trial
population and the mainland Chinese trial population at least 740 subjects will be recruited in 
mainland China. The remaining subjects will be recruited from other Asian countries and regions.
Sample Size Monitoring
The overall ongoing pregnancy rate will be monitored in a blinded manner, as the number of 
subjects to be randomised may need to be increased beyond the planned 1,000, if the overall 
ongoing pregnancy rate observed in the trial is above the estimated 32.2% used for the sample size 
calculation. The expected maximum number of subjects to be randomised would then be 
approximately 1,144 (572 per treatment group), corresponding to an observed rate of 50%. Blinded 
monitoring of the assumptions underlying the sample size is recommended specifically for non-
inferiority trials by Food and Drug Administration (FDA) and in general by EMA.
Primary Endpoint: Ongoing Pregnancy Rate
The non-inferiority hypothesis to be tested for the primary endpoint is
H0: FE - GF -10.0% against the alternative HA: FE - GF > -10.0%,
where FE and GF denote the ongoing pregnancy rate after treatment with FE 999049 and 
GONAL-F, respectively. Non-inferiority will be evaluated based on the overall trial population.
The null hypothesis (H0) will be tested against the alternative (HA) by constructing a two-sided 95% 
confidence interval for the difference in ongoing pregnancy rates. The primary analysis will be 
adjusted for the stratification factor (age group) by using the Mantel-Haenszel method to combine 
results across age groups. In brief, this corresponds to deriving a weighted average across age 
groups where the weight depends on the number of observations in each treatment group in each 
age stratum.
Evaluation of the Primary Objective
If the lower limit of the two-sided 95% confidence interval based on the overall population is
greater than the non-inferiority limit (-10.0%) for both the full analysis set (FAS) and the PP 
analysis set, the null hypotheses will be rejected. In that case it will be claimed that FE 999049 is

non-inferior to GONAL-F with respect to ongoing pregnancy rate in women undergoing controlled 
ovarian stimulation.
If the lower limit of the two-sided 95% confidence interval for the treatment difference based on the 
FAS not only lies above the non-inferiority limit (-10.0%) but also above zero then there is 
evidence of superiority in terms of statistical significance at the 5% level. The result based on the 
PP analysis set is not essential for the superiority claim but should lead to a comparable result for a 
robust interpretation.
A supportive evaluation of the subjects recruited in mainland China will be conducted, and it is 
expected that the findings among the mainland Chinese trial population will be consistent with the 
overall findings in the trial.

INTRODUCTION
1.1
Background
FE 999049 is a human recombinant follicle-stimulating hormone (rFSH) belonging to the 
pharmaceutical class of gonadotropins. It is intended for the following indication: “Controlled 
ovarian stimulation for the development of multiple follicles in women undergoing assisted 
reproductive technologies (ART) such as an in vitro fertilisation (IVF) or intracytoplasmic sperm 
injection (ICSI) cycle”. FE 999049 will be delivered as a solution for injection for subcutaneous 
self-administration by an injection pen.
FE 999049 is expressed from a host cell line of human fetal retinal origin (PER.C6®). The PER.C6®
cell line is well-characterised, and bio-testing of the master cell bank has demonstrated safety and 
consistency. FE 999049 is a glycoprotein which is composed of two non-covalently bound 
polypeptide chains, denoted alfa (α) and beta (β). The α-subunit contains 92 amino acid residues 
with 5 intrachain-disulphide bonds. The β-subunit contains 111 amino acid residues with 
6 intrachain-disulphide bonds. Each subunit is N-glycosylated at two positions, and about 40% of 
the total mass is carbohydrates.
There are no commercially available rFSH products derived from human cell lines, but Ferring has 
recently submitted a Marketing Authorisation Application to the European Medicines Agency 
(EMA) for FE 999049 (October 2015) and received positive opinion from the Committee for 
Medicinal Products for Human Use (October 2016). Currently-approved rFSH products for the 
proposed indication, such as follitropin alfa (GONAL-F, Merck Serono) and follitropin beta 
(PUREGON, MSD), are derived from a Chinese hamster ovary (CHO) cell line. The amino acid 
sequence of FE 999049 is identical to the endogenous human FSH sequence and to that in existing 
CHO-derived rFSH products. Manufacturing from different cell systems leads to glycosylation 
heterogeneity between rFSH preparations. The glycosylation profile of recombinant proteins is 
dependent on the expressing cell line and the cell culture conditions. Differences in glycosylation
profile, sialic acid pattern and isoform profile, have been documented between FE 999049 and 
existing rFSH products from a CHO cell line. Comparison between the FE 999049 and the
GONAL-F and PUREGON profiles indicate differences in acidity and carbohydrate side chains. As 
CHO cells lack enzymatic functions to construct more complex carbohydrate structures found in 
humans, the glycosylation profile of FE 999049 is more complex. In addition, FE 999049 contains 
both α2,3 and α2,6 sialylation patterns, while CHO-derived rFSH products exclusively carry 
2,3 linked sialic acid; this difference further contributes to the observed differences in glycosylation 
profiles between FE 999049 and CHO-derived rFSH products.
Before the current trial, Ferring has completed four phase 1 trials, two phase 2 dose-response trials
(one conducted in EU and one in Japan) and two phase 3 trials as part of the clinical development 
programme for FE 999049. A total of 1,927 subjects have been included in the completed clinical 
trials, of whom 1,112 subjects were exposed to FE 999049. 
The two phase 2 trials were randomised, controlled, assessor-blind, multi-centre dose-response 
trials in which randomisation was stratified according to the subject’s anti-Müllerian hormone 
(AMH) level at screening. In both trials, a statistically significant dose-response relationship for 
FE 999049 with respect to the number of oocytes retrieved was observed for the overall population 
and for each AMH strata. Furthermore, the dose-response profile observed in Japanese and 
European subjects was similar. An individualised FE 999049 dosing regimen based on subject’s

AMH level and body weight was designed by modelling and simulation and prospectively tested in 
the phase 3 trials.  
During the phase 3 trials, 665 IVF/ICSI subjects were treated with FE 999049 in 1,012 treatment 
cycles. The two phase 3 trials supported the efficacy and safety of FE 999049 in the proposed 
indication. ESTHER-1 (trial 000004, Evidence-based Stimulation Trial with Human rFSH in 
Europe and Rest of World, ESTHER) was an efficacy trial designed to demonstrate non-inferiority 
of FE 999049 versus an approved recombinant FSH preparation with ongoing pregnancy rate and 
ongoing implantation rate as co-primary endpoints (as agreed with the EMA during Scientific 
Advice) and also to prospectively evaluate the outcome of the stratified medicine approach with the 
individualised FE 999049 dosing regimen based on the AMH level (measured by Elecsys® AMH 
Immunoassay, Roche Diagnostics) and body weight. ESTHER-2 (trial 000071) was a safety 
immunogenicity trial with up to two repeated treatment cycles in subjects who did not achieve an 
ongoing pregnancy in ESTHER-1. Both trials have been completed with respect to their 
intervention part.
The ESTHER-1 trial demonstrated non-inferiority of FE 999049 to GONAL-F for the two co-
primary endpoints, ongoing pregnancy rate and ongoing implantation rate, for both the per-protocol 
(PP) and modified intention-to-treat (mITT) populations. Across treatment groups and analysis 
populations, the ongoing pregnancy rate was in the range 31-33% and the ongoing implantation rate 
in the range 35-37%. 
The AMH dosing regimen for FE 999049 in controlled ovarian stimulation cycles led to a 
statistically significantly lower proportion of subjects with extreme ovarian response (<4 or ≥15 
oocytes retrieved or <4 or ≥20 oocytes retrieved) compared to the GONAL-F group, when adjusted 
for AMH. Furthermore, the value of the individualised FE 999049 dosing regimen was reflected in 
statistically significant and clinically relevant reductions in ovarian hyperstimulation syndrome 
(OHSS) risk management compared to GONAL-F. Overall, the incidence of preventive 
interventions for early OHSS among subjects treated with FE 999049 was half of that observed 
with GONAL-F, which was a statistically significant reduction. The combined incidence of early 
OHSS (all and those of moderate/severe grade) and/or preventive interventions for early OHSS was 
also statistically significantly reduced with FE 999049 in comparison to GONAL-F. Overall, there 
was a statistically significantly lower incidence of total OHSS and/or preventive interventions for 
early OHSS, and of total moderate/severe OHSS and/or preventive interventions for early OHSS 
with FE 999049 compared to GONAL-F.
A design similar to the phase 3 trial ESTHER-1 is being proposed for the present trial to be 
conducted in mainland China and other Asian countries and regions, with some modifications 
according to local practice. The primary objective of this trial is to demonstrate non-inferiority of 
FE 999049 compared with GONAL-F with respect to ongoing pregnancy rate in women 
undergoing controlled ovarian stimulation.
For further information regarding FE 999049, please refer to the current edition of Investigator’s 
Brochure.
1.2
Scientific Justification for Conducting the Trial
The present trial is a phase 3 trial designed to assess the efficacy and safety of the human-derived 
rFSH preparation FE 999049 in women undergoing controlled ovarian stimulation for the 
development of multiple follicles for ART. FE 999049 is the first rFSH preparation derived from a

human cell line. The dosing regimen for FE 999049 will be individualised for each woman based 
on her AMH level and body weight. The trial will support the registration of FE 999049 in 
mainland China and other Asian countries and regions.
1.3
Benefit / Risk Aspects
Benefits
The treatment cycle is provided to the participating subjects free of charge, as Ferring compensates 
the investigational sites for their expenses. Subjects participating in this trial may benefit by
achieving pregnancy. Subjects will be closely monitored, and they will have either the same or 
more frequent visits to the clinic compared to routine treatment, depending on local practice. In 
addition, the data obtained from the treatment cycle may provide useful information for optimising 
the ovarian response and for clinical planning of subsequent treatment cycles.
Risks
The risks associated with ART treatment, including the risks associated with controlled ovarian 
stimulation and clinical and laboratory procedures, are explained to the subjects as part of the
counselling prior to starting treatment.
Gonadotropins
In this trial, controlled ovarian stimulation will be performed either with the individualised 
FE 999049 dosing regimen or with GONAL-F, a widely available recombinant FSH preparation 
used in line with its approved labelling. Both preparations will be administered subcutaneously.
To date, a total of 1,112 women have been exposed to FE 999049 in completed phase 1, 2 and 3
trials. The overall adverse event profile of the individualised FE 999049 dosing regimen appeared 
to be comparable to that of GONAL-F with the exception of fewer OHSS and/or preventive 
interventions with FE 999049. The most frequently reported adverse drug reactions during 1,012 
treatment cycles with FE 999049 in the phase 3 programme were headache, pelvic discomfort,
OHSS, pelvic pain, adnexa uteri pain, nausea and fatigue (all reported as common, i.e. 1% to 
< 10%). Uncommon adverse drug reactions reported with FE 999049 were diarrhoea, dizziness, 
mood swings, constipation, vomiting, abdominal discomfort, breast pain, breast tenderness, vaginal 
haemorrhage and somnolence. FE 999049 administered with the injection pen was well-tolerated 
with a low incidence of local injection site reactions. The severity of local injection site reactions 
was in general mild and comparable to that reported for GONAL-F administrated with the pre-filled 
pen.
The FE 999049 dosing regimen used in this trial is an individualised dosing regimen based on the 
subject’s AMH and body weight. AMH is a well-established predictor of ovarian response to 
gonadotropin treatment and was confirmed to be the best endocrine marker of ovarian response to 
FE 999049 treatment in the phase 2 trial. The FE 999049 dosing is based on the Elecsys® AMH 
assay from Roche Diagnostics which displays better performance with less variability than other 
AMH assays.3
GONAL-F is a commercially available CHO-derived rFSH preparation with established safety and 
efficacy4. The most frequent adverse events in relation to use of GONAL-F are as follows: 
headache, ovarian cysts and injection site reactions (all reported as very common, i.e. ≥10%) and

abdominal pain, abdominal distension, abdominal discomfort, nausea, vomiting, diarrhoea and mild 
or moderate OHSS including associated symptomatology (all reported as common, i.e. 1% to 
<10%)4. The GONAL-F dosing regimen used in this trial is in line with labelling recommendations.
Concerning well-known risks associated with the use of gonadotropin products for ovarian 
stimulation, subjects are closely monitored throughout the trial. The most serious risk associated 
with gonadotropin treatment is OHSS. OHSS manifests itself with increasing degrees of severity. 
Moderate/severe OHSS is associated with marked ovarian enlargement, fluid accumulation and 
other complications. Early OHSS can potentially be prevented by withholding gonadotropins, 
withholding human chorionic gonadotropin (hCG) or administering gonadotropin-releasing 
hormone (GnRH) agonist for triggering of final follicular maturation. Very rare cases of serious 
allergic reactions have been reported after injection of gonadotropins. Concerning immunogenicity, 
the risk of treatment-induced anti-drug-antibodies for gonadotropin products is very low (estimated 
to be 0-2%5,6,7,8,9,10,11) and no safety or efficacy concern has been identified with regards to 
immunogenicity with FE 999049 or with the available rFSH preparations.
Procedures and Concomitant Fertility Medications
Subjects will undergo standard ART treatment procedures (e.g. transvaginal ultrasound, blood 
sampling, oocyte retrieval and transfer) and also receive concomitant fertility medication as part of 
the treatment cycle in this trial. The transvaginal ultrasound examinations may be associated with 
mild discomfort and a very rare risk of infection. The blood sampling might be associated with mild 
discomfort, bruising and a very rare risk of infection. The oocyte retrieval procedure is associated 
with discomfort and very rarely infections and bleeding. The transfer procedure is associated with 
mild discomfort and very rarely infections and mild bleeding. The concomitant fertility medications 
are approved products and are considered generally well-tolerated. The most frequently reported
adverse events with these concomitant medication products are similar to those reported for FSH 
preparations, such as headache, injection site reactions, pelvic pain, abdominal pain, abdominal 
distension and allergic reactions. Furthermore, the vaginal progesterone has been associated with 
vulvovaginal disorders and uterine spasms (at a frequency of 1-2%).
Pregnancy-related Events
A serious concern associated with ART cycles is the frequency of multiple pregnancies / births and 
the related neonatal health problems. To minimise the risk of multiple gestations, subjects will have 
transfer of 1 or 2 embryos of the highest quality available. The incidence of miscarriage and ectopic 
pregnancy is higher in women undergoing controlled ovarian stimulation than in women conceiving 
spontaneously, though the risk of ectopic pregnancy is mainly higher in patients with a history of 
tubal infertility. Furthermore, the prevalence of congenital malformations after ART may be 
slightly higher than after spontaneous conceptions; this is thought to be due to differences in 
parental characteristics (e.g. maternal age and sperm characteristics) and multiple pregnancies.

Benefits / Risks
Participation in this trial is not expected to have a negative influence on the subject’s likelihood of 
conceiving compared to normal clinical practice. Furthermore, participation does not imply extra 
risks for the subjects in comparison to routine controlled ovarian stimulation. In conclusion, the 
evaluation of benefits and risks indicate that participation in this trial is associated with a
favourable benefit-risk ratio.

Overall Design and Control Methods
Trial Design 
This will be a randomised, controlled, assessor-blind, parallel groups, multicentre, Pan-Asian non-
inferiority trial comparing the efficacy and safety of two rFSH preparations, FE 999049 and 
follitropin alfa (GONAL-F), in first cycle subjects aged 20-40 years undergoing controlled ovarian 
stimulation for IVF/ICSI following a GnRH antagonist protocol. The trial has been designed to 
demonstrate non-inferiority of FE 999049, a human cell line-derived rFSH preparation, versus an 
approved CHO-derived rFSH preparation, i.e. GONAL-F, with ongoing pregnancy rate as the 
primary endpoint. Secondary endpoints include pharmacokinetic profile of FE 999049, 
pharmacodynamic parameters of FSH action as well as efficacy and safety parameters related to 
controlled ovarian stimulation. The assessor-blind design ensures that the investigators and other 
assessors such as embryologists and central laboratory personnel are blinded to individual treatment 
allocation. The sponsor will break the blind when all subjects have completed the end-of-trial visit, 
in order to evaluate efficacy and safety up to the ongoing pregnancy visit.
Subjects will be screened within 90 days prior to randomisation for compliance with the inclusion 
and exclusion criteria. On day 2-3 of the menstrual cycle, subjects will be randomised in a 1:1 ratio 
to treatment with either FE 999049 or GONAL-F, and stimulation will be initiated. Randomisation 
will be stratified by centre and according to age (<35, 35-37 and 38-40 years). Subjects randomised 
to FE 999049 will have their individual dose determined on the basis of their AMH level at 
screening and their body weight at randomisation. The daily FE 999049 dose will be fixed 
throughout the stimulation period. For subjects with low AMH (<15 pmol/L) the daily FE 999049 
dose is 12 μg, irrespective of body weight. For subjects with high AMH (≥15 pmol/L) the daily 
FE 999049 dose is on a continuous scale ranging from 0.19 to 0.10 μg/kg, i.e. dependent on actual 
AMH and body weight (note, the minimum and maximum allowed daily doses are 6 µg and 12 µg, 
respectively). Subjects can be treated with FE 999049 for a maximum of 20 days, and coasting is 
not allowed. For subjects randomised to GONAL-F, the dosing regimen is within labelling. The 
starting daily dose of GONAL-F is 150 IU and fixed for the first five stimulation days after which it 
may be adjusted by 75 IU per day based on the individual response. The maximum daily 
GONAL-F dose allowed is 450 IU. Subjects can be treated with GONAL-F for a maximum of 
20 days, and coasting is not allowed. 
During stimulation, subjects will be monitored by transvaginal ultrasound on stimulation day 1 and 
6 and hereafter at least every second day. When the leading follicle reaches ≥15 mm, visits must be 
performed daily. To prevent a premature LH surge, a GnRH antagonist will be initiated on 
stimulation day 6 and continued throughout the stimulation period. Triggering of final follicular 
maturation will be done as soon as ≥3 follicles with a diameter ≥17 mm are observed. If there are 
<25 follicles with a diameter ≥12 mm, hCG will be administered. If there are 25-35 follicles with a 
diameter ≥12 mm, a GnRH agonist can be administered or the cycle can be cancelled. In case of 
excessive follicular development, defined as >35 follicles with a diameter ≥12 mm, the cycle is to 
be cancelled. If it is judged by the investigator that ≥3 follicles with a diameter ≥17 mm cannot be 
reached, but 1 or 2 follicles with a diameter ≥17 mm are observed, the cycle may either be 
cancelled due to poor follicular development or triggering of final follicular maturation is to be 
induced, as judged by the investigator.

Oocyte retrieval will take place 36h (±2h) after triggering of final follicular maturation and the 
oocytes can be inseminated by IVF or ICSI. Rescue ICSI is not allowed. Fertilisation and embryo 
development will be assessed from oocyte retrieval to the day of transfer. For subjects who 
underwent triggering of final follicular maturation with hCG, transfer is performed on day 3 
(embryo stage) after oocyte retrieval. Subjects <35 years at randomisation will have single embryo 
transfer if a good-quality embryo is available; otherwise, double embryo transfer will be performed 
(and single transfer if two embryos are not available). Subjects ≥35 years at randomisation will 
have double embryo transfer (and single transfer if two embryos are not available). Remaining 
embryos may be cryopreserved in accordance with local guidelines and/or regulations. For subjects 
who underwent triggering of final follicular maturation with GnRH agonist, no transfer will take 
place in the current fresh cycle and the embryos available will be cryopreserved on day 3, 5 or 6,
according to local practice. All cryopreserved embryos can be used by the subject after completion 
of the trial, in accordance with local guidelines and/or regulations. 
Vaginal progesterone will be provided for luteal phase support from the day of oocyte retrieval or 
the day after and at least until clinical pregnancy. Thereafter the investigator may decide to 
continue up to the ongoing pregnancy visit, according to local practice. Progesterone administration 
should not continue if menses, negative βhCG or pregnancy loss occurs. A serum βhCG test will be
performed 13-15 days after transfer, clinical pregnancy will be confirmed by transvaginal 
ultrasound 5-6 weeks after transfer, and ongoing pregnancy will be confirmed by transvaginal or 
abdominal ultrasound 10-11 weeks after transfer. 
Blood samples will be collected throughout the trial for the purpose of evaluating the endocrine 
profile, clinical chemistry and haematology parameters as well as anti-FSH antibodies. Endocrine 
parameters are assessed at screening, stimulation day 1, stimulation day 6 and end-of-stimulation, 
and furthermore FSH is also assessed at oocyte retrieval. Clinical chemistry and haematology 
parameters are assessed at screening, stimulation day 1, end-of-stimulation and end-of-trial. Anti-
FSH antibodies are collected at four occasions. The first blood sample is taken at the screening visit 
and is exclusively used as back-up samples for the anti-drug antibody assay development. The 
subsequent three samples are used for analysis of anti-FSH antibodies in the individual subjects in 
the trial, and are taken prior to dosing on stimulation day 1 and at two occasions post-dosing: 5-10 
days after the last FE 999049 or GONAL-F dose (it may coincide with the transfer visit) and 19-28 
days after the last FE 999049 or GONAL-F dose (it may coincide with the βhCG test visit). 
Subjects with a treatment-induced anti-FSH antibody response will be followed until the response 
has become negative or returned to the pre-dosing level, with a maximum follow-up period of one 
year. 
Local tolerability of FE 999049 and GONAL-F following subcutaneous administration will be 
assessed by the subject three times daily: immediately, 30 minutes and 24 hours after each 
injection. The assessment of injection site reactions will be made throughout the stimulation period 
and recorded by the subjects in a diary. 
Post-Trial Activities
Post-trial activities cover pregnancy and neonatal health follow-up. All subjects with an ongoing 
pregnancy will be followed till delivery to gather information on live birth rate. Furthermore, data 
will be gathered on neonatal health, including any congenital anomalies, at birth and at 4 weeks 
after birth. These data will be reported separately.

Planned Number of Trial Sites and Subjects
It is planned to randomise 1,000 subjects from 15-30 sites in mainland China and other Asian 
countries and regions. Of the 1,000 subjects it is expected that 740 subjects will be recruited in 
mainland China (i.e. possessing a Chinese identification card and having native Chinese parents)
and the rest from other Asian countries and regions, potentially Taiwan, South Korea and Vietnam.
It is estimated that approximately 1,200 subjects should be screened to achieve 1,000 subjects 
eligible for randomisation. 
The assumptions underlying the sample size calculations will be monitored in a blinded manner 
(see sections 3.3, 9.1 and 9.10), and the number of randomised subjects may be adjusted up to a 
maximum of approximately 1,144 subjects, corresponding to an observed ongoing pregnancy rate 
of 50%.
3.3
Interim Analysis and Administrative Review
No interim analysis intended to compare treatment groups with respect to efficacy or safety is 
planned. 
The overall ongoing pregnancy rate will be monitored in a blinded manner. This monitoring will be 
performed by the project statistician who will evaluate the overall ongoing pregnancy rate in 
relation to the assumptions underlying the sample size.

Data Monitoring Committee
No Data Monitoring Committee will be established for this trial.

Discussion of Overall Trial Design and Choice of Control Groups
3.5.1
Trial Design
The primary objective of the trial is to demonstrate non-inferiority of FE 999049 compared with 
GONAL-F with respect to ongoing pregnancy rate in women undergoing controlled ovarian 
stimulation.
Strict criteria have been incorporated in the design of this comparative trial to properly assess the 
effect of the interventions on treatment outcome. In general, standardisation of criteria, timing of 
assessments, procedures and interventions have to a great extent been incorporated in the design of 
this trial to minimise variation12,13,14.

This is a randomised controlled trial using an approved gonadotropin preparation as active 
comparator. It is a parallel group design restricted to a single treatment cycle, as this design is 
preferred over a cross-over design in fertility trials. The trial will be open-label but assessor-blind. 
A double-blind design is not considered feasible for the present trial for various practical reasons, 
which are described in detail in section 3.5.3. The assessor-blinding will ensure blinding and 
thereby unbiased evaluation by the investigators, embryologists and central laboratory personnel. 
Similarly, Ferring staff will also remain blinded to individual subject treatment allocation during 
the conduct of the trial. The trial will be a multi-centre Pan-Asian trial. This set-up ensures that the 
required number of subjects can be recruited within a reasonable time and also has the advantage 
that it should facilitate subsequent generalisation of the results.
The trial is designed to demonstrate non-inferiority of FE 999049 versus GONAL-F with respect to 
ongoing pregnancy rate. The non-inferiority margin for the primary endpoint has been set at -10.0% 
(absolute) in line with other recent large randomised controlled trials in ART15,16,17 and the power is 
90% for the overall trial population and 80% power for the mainland Chinese population. A non-
inferiority margin of -8.0% (and a power of 80%) has been implemented in the pivotal phase 3 trial 
(ESTHER-1). However, the present phase 3 trial to be conducted in mainland China and other 
Asian countries and regions will not be a stand-alone trial but will be supported by the ESTHER-1 
trial conducted in Europe and the Rest of World, arguing for a less strict non-inferiority limit in the 
present trial. Furthermore, narrowing the non-inferiority margin with 2% points (i.e. from -10.0% to
-8.0%) would increase the sample size by 516 subjects but would only reduce the maximum 
allowed difference in the point estimates for the ongoing pregnancy rate for FE 999049 required to 
demonstrate non-inferiority versus the comparator, by 0.8% (further details are provided in 
section 9.1), which is not clinically relevant.
Subjects will undergo controlled ovarian stimulation with an individualised dosing regimen of 
FE 999049 based on the subject’s AMH level and body weight, or with a labelling recommended 
dosing regimen of GONAL-F, following a GnRH antagonist protocol. The daily FE 999049 dose is 
fixed throughout the stimulation period in this trial. The daily GONAL-F dose is fixed for the first 
five stimulation days after which it may be adjusted by 75 IU per day based on the individual 
response, which is within the recommendations in the labelling. The selection of doses is described 
in detail in section 3.5.4. Monitoring of ovarian response by transvaginal ultrasound and blood 
sampling for assessment of several endocrine parameters will be performed regularly during 
stimulation.
Oocytes will be inseminated by either IVF or ICSI reflecting the procedures used in the target 
population for the proposed indication. Embryos will be cultured for 3 days and embryo 
development will be assessed from oocyte retrieval till the day of transfer, allowing evaluation of 
embryo development until cleavage stage. The duration of culture in this trial is adapted to clinical 
practice in Asia where transfer on day 3 after oocyte retrieval is the most common. In contrast, 
culture to blastocyst stage and transfer on day 5 after oocyte retrieval are incorporated in the 
phase 3 trial ESTHER-1, reflecting clinical practice in the participating countries in that trial.
The present protocol requires single or double embryo transfer on day 3 for all women, depending 
on age, with at least one good-quality embryo available. The scientific justification for 
incorporating these features is that it will ensure that the data obtained in this trial are in line with 
the current clinical directions taken for maintaining efficacy (i.e. ongoing pregnancy rates) and 
minimising risks (i.e. multiple pregnancies)18,19,20. The embryo transfer policy in this trial has been

adapted to clinical practice in Asia, and is not identical to the policy in the ESTHER-1 trial where 
single embryo (blastocyst) transfer is more strictly enforced.
Luteal phase support of the endometrium will be provided via vaginal progesterone. The 
progesterone product used in ESTHER-1 is not approved in all Asian countries and regions and 
therefore another progesterone product which is approved in mainland China and the other 
participating Asian countries and regions will be used in the present trial. Furthermore, luteal phase 
support in this trial continues to at least the clinical pregnancy visit while it was stopped at the
βhCG visit in ESTHER-1; this is a reflection of differences in local clinical practice.
Subjects who achieve a pregnancy will be followed till live birth to collect information on 
pregnancy outcome. In addition, neonatal health data will be gathered at birth and at 4 weeks after 
birth. These data will be reported separately.
3.5.2
Selection of Endpoints
The ultimate objective of fertility treatment is live birth. Ongoing pregnancy is considered an 
appropriate primary endpoint for efficacy trials, as ongoing pregnancy is the best predictor of live 
birth and it is definable within a time period in which other potential confounding factors are more 
easily controlled14.
One of the secondary objectives is to compare the clinical benefits of FE 999049 in its dosing 
regimen to those of GONAL-F with respect to efficacy and safety. This objective is addressed by 
multiple endpoints to address it from several angles; i.e. proportion of subjects with extreme 
ovarian response, early OHSS (including moderate/severe grade), preventive interventions for early 
OHSS, cycle cancellations due to poor ovarian response development and cycle cancellation due to 
excessive ovarian response.
Additional secondary endpoints include pharmacodynamic parameters, such as ovarian response in 
terms of follicular development, endocrine profile and oocytes retrieved, and also oocyte / embryo 
quality. Follicular development and endocrine profile will be evaluated after the initial 5 days (i.e. 
before any potential dose adjustments in the GONAL-F group and before start of the GnRH 
antagonist) as well as at the end of stimulation. The endocrine profile consists of FSH, luteinising 
hormone (LH), estradiol, progesterone, inhibin A and inhibin B. Serum FSH levels will be used to 
assess the population pharmacokinetics associated with repeated dosing of FE 999049, which is 
also a secondary endpoint. 
Clinical safety endpoints cover adverse events, early and late OHSS, preventive interventions for 
early OHSS, local tolerability, clinical chemistry and haematology parameters, immunogenicity and 
pregnancy-related events (i.e. multi-fetal gestations, biochemical pregnancies, spontaneous 
abortions, ectopic pregnancies and vanishing twins). Pre-defined local tolerability reactions, i.e. 
redness, pain, itching, swelling and bruising, will be assessed by the subjects on three occasions 
spanning from immediately after the subcutaneous injection till 24 hours after. Presence of anti-
FSH antibodies will be evaluated 5-10 and 19-28 days after the last administration of FE 999049 or 
GONAL-F for assessment of a potential immunoglobulin M (IgM) response and a fully mounted 
immunoglobulin G (IgG) immune response, respectively21,22,23. Technical malfunction of the pens 
used for administration of the gonadotropin preparations will also be monitored.
Post-trial activities cover follow-up of ongoing pregnancies up to live birth. Neonatal health data at 
birth and at 4 weeks after birth will be gathered.

In conclusion, the list of primary and secondary endpoints is appropriate for an efficacy trial and 
furthermore includes items of special interest considering the profile of FE 999049 and specific
recommendations from EMA.
3.5.3
Blinding
The two investigational medicinal products (IMPs) differ in presentation as FE 999049 is provided 
as a liquid in a cartridge to be administered via an injection pen whereas GONAL-F is provided as a 
liquid in a pre-filled pen. Furthermore, GONAL-F is manufactured by Merck Serono and bought 
commercially for use in this phase 3 trial. Therefore, a double-blind, double-dummy design is not 
feasible. The trial, however, is assessor-blind, ensuring unbiased evaluation by the investigators, 
embryologists and central laboratory personnel. 
One or more trial medication delegate(s) will be identified at each site. The trial medication 
delegate will be responsible for all trial medication related issues, both practically at the clinic and
in interactions with the subject. To maintain the assessor-blinding, the trial medication delegate is 
not allowed to perform any assessments in the trial. Information on treatment allocation is only 
available to the trial medication delegate. The investigator does not have access to these modules in 
the electronic case report form (e-CRF). Thus, only the trial medication delegate at the site, the 
monitors and the participating subjects will know the treatment allocation once the subjects are 
randomised. Precaution will be taken to ensure that the treatment allocations are not available to the 
investigators or other assessors throughout the trial. Subjects will be clearly instructed to only 
discuss their treatment allocation with the trial medication delegate, and to not mention it to the 
investigator.
Drug accountability forms and other forms identifying treatment allocation are kept unavailable to 
the investigator. The subject will during the informed consent process be informed, both verbally 
and in writing, to not disclose her treatment allocation to the investigator. Trial staff is provided 
training in the importance of maintaining blinding, and trial medication delegates are also helped to 
set up systems at the clinic.
The trial medication delegate will dispense the trial medication to the subject (and may also do the 
actual administration at the clinic, if required). The investigator will, based on the follicular 
development, judge if dose adjustments are recommended and state his/her directions on a form 
developed for that purpose, which will be used to inform the trial medication delegate. Depending 
on whether the subject is being treated with FE 999049 or GONAL-F, the trial medication delegate
will provide detailed instructions to the subject in line with the dosing regimen for each preparation
as outlined in the protocol. In other words, if the investigator recommends a dose adjustment, the 
trial medication delegate will implement a decrease or increase of 75 IU per day as applicable if the 
subject is in the GONAL-F group, while no dose adjustments will be implemented if the subject is 
in the FE 999049 group. Requests for cycle cancellation due to inappropriate response or other 
medical reasons are followed, irrespective of treatment group.
The Ferring clinical trial team (i.e. data manager, statistician, trial manager, medical writer, 
pharmacovigilance manager and sponsor’s responsible medical officer) will be blinded to treatment 
allocation until breaking of the blind. The blind will be broken when all subjects have completed 
the end-of-trial visit and the trial database is declared clean and locked.

3.5.4
Selection of Doses in the Trial
FE 999049
Modelling and simulation based on the efficacy and safety data obtained in the European phase 2 
trial have been used to establish the overall dosing regimen for FE 999049 in the phase 3 trials. 
This is the same dosing regimen that was used in the phase 3 trial 000004 (ESTHER-1), where it 
has been shown to reduce the risk of extreme ovarian response, the risk of cycle cancellation due to 
excessive ovarian response, and the risk of early moderate/severe OHSS and/or prevention 
interventions for early OHSS, while obtaining a pregnancy rate that is non-inferior to GONAL-F.
AMH and body weight were found to influence the dose-response with regard to obtaining the aim 
of the model of the FE 999049 dosing regimen. The impact of body weight on ovarian response is 
clinically relevant for low dose levels of FE 999049, while the effect is only minor at dose levels of 
12 μg and above. The individualised dosing regimen of FE 999049 in the present trial is described 
in detail in section 5.1.1 and is summarised as follows: For subjects with low AMH (<15 pmol/L)
the daily FE 999049 dose is 12 μg, irrespective of body weight, and for subjects with high AMH
(≥15 pmol/L) the daily FE 999049 dose is on a continuous scale ranging from 0.19 to 0.10 μg/kg, 
depending on the baseline AMH level. The minimum and maximum allowed daily doses are 6 µg 
and 12 µg, respectively.
GONAL-F
Subjects randomised to GONAL-F will be dosed according to the approved labelling. The starting 
dose of GONAL-F in this trial is 150 IU, which is the same starting dose as used in the ESTHER-1
trial. The European4, mainland Chinese24, Taiwanese25, South Korean26 and Vietnamese27
labelling’s for GONAL-F state a starting dose of 150-225 IU, but provide no recommendation for 
when to use 150 IU and when to use 225 IU. In the absence of a recommendation from the 
manufacturer, the lowest effective dose has been selected as this would be a reasonable approach in 
clinical practice, especially as this trial will include subjects with no previous controlled ovarian 
stimulation for IVF/ICSI. This choice is also in line with the US labelling of GONAL-F28 which 
recommends a starting dose of 150 IU in patients where the endogenous gonadotropin levels are not 
suppressed (such as the GnRH antagonist cycle, where prevention of premature LH surge is only 
initiated after 5 days of stimulation). The GONAL-F starting dose is fixed for the first five 
stimulation days after which it may be adjusted by 75 IU per day based on the individual response. 
For GONAL-F, the maximum daily dose allowed is 450 IU. 
Concomitant Fertility Medication 
The doses and overall treatment regimens for the GnRH antagonist, hCG and progesterone products 
are in line with the recommendations in the respective products’ labelling for the indication of ART
and/or standard clinical practice. The GnRH agonist is included as an option for triggering of final 
follicular maturation in subjects with 25-35 follicles with a diameter ≥12 mm, as this approach is 
associated with almost an elimination of the risk of early moderate/severe OHSS despite high 
ovarian response. The use of a GnRH agonist for triggering of final follicular maturation in a GnRH 
antagonist protocol is well-described in the literature and considered an acceptable alternative to 
cycle cancellation29,30,31,32,33.

3.5.5
Selection of the Trial Population
This trial will include women undergoing their first IVF/ICSI cycle, as this group of subjects is 
considered the most appropriate population for a trial comparing the efficacy between 
gonadotropins and furthermore when using different dosing regimens. The subjects have been
diagnosed with tubal infertility, unexplained infertility, endometriosis stage I/II or have partners 
diagnosed with male factor infertility, and are considered eligible for IVF or ICSI. The trial will 
include women up to 40 years of age and will thereby cover the patient age span in which most 
ART treatments are performed. The allowed body mass index (BMI) is 17.5-32.0 kg/m2, thus 
including underweight, normal weight, overweight and obese subjects.
The exclusion criteria incorporate the contraindications for the use of gonadotropins.
Altogether, the population selected for this trial would be expected to be representative for patients 
undergoing controlled ovarian stimulation in IVF/ICSI cycles.
3.5.6
Follow-up Procedures
Post-trial Activities
Post-trial activities cover pregnancy and neonatal health follow-up at birth and at 4 weeks after 
birth as described in section 7.4.1. 
Safety Follow-up
As a safety precaution, subjects with treatment-induced anti-FSH antibody response will be 
followed until the response has become negative or returned to the pre-dosing level for at least 2 
consecutive measurements with a maximum follow-up period of one year .The assessments will 
also be terminated if the subject commences a new treatment cycle with any gonadotropin 
preparation. Safety follow-up also includes follow-up on adverse events (with onset during the trial 
and classified as serious or related to IMP) until it is resolved or until the medical condition of the 
subject is stable.
Access to Therapy after End-of-trial
Concerning access to therapy after completion of the trial, FE 999049 is currently under clinical 
development and cannot be offered to subjects after participation in this clinical trial. However, 
several gonadotropin preparations are approved for controlled ovarian stimulation and are 
commercially available.

Method of Assigning Subjects to Treatment Groups
4.2.1
Recruitment
The participating subjects will be recruited among the patients attending the clinics included in the 
trial. Advertisements may be used if approved by the local ethics committee and regulatory 
authorities, as applicable according to local regulations.
A screening number is allocated to each subject who has given written informed consent to 
participate in the trial. A subject must always be assigned to the lowest available screening number 
at each site. A subject screening / enrolment log for all screened subjects must be maintained by the 
investigator.
4.2.2
Randomisation
On day 2-3 of the menstrual cycle, subjects will be randomised in a 1:1 ratio to treatment with 
either FE 999049 or GONAL-F, and stimulation will be initiated. Randomisation is performed 
centrally through the e-CRF and will be stratified according to age (<35, 35-37 and 38-40 years).
The randomisation number will be allocated to the subject together with the treatment allocation 
and starting dose. When a subject is randomised to the trial, she will always be assigned to the 
lowest available randomisation number. An independent statistician at the Ferring Global 
Biometrics Department will prepare a computer-generated randomisation list and randomisation is 
performed in blocks. Blocks will be maintained within trial sites, i.e. the randomisation will be 
stratified by trial site. The block size will only be revealed when the trial database is declared clean 
and locked. An overview of recruitment will be recorded on a subject identification code list for all 
randomised subjects kept by the investigator.

Restrictions
4.3.1
Prior and Concomitant Therapies
The subjects must not have used fertility modifiers, including DHEA, metformin or cycle 
programming with oral contraceptives, progestogen or estrogen preparations, or hormonal 
preparations (except for thyroid medication) during the last menstrual cycle before randomisation.
The subject must also not use metformin as ongoing treatment during the trial.
During the trial it is prohibited to administer any other fertility medications, than the ones provided 
as part of the trial regimen.
Dopamine agonist for preventive intervention of OHSS is not allowed.
4.3.2
Prohibited Therapy
It is prohibited to continue therapy outside the scope of the trial with medicinal products provided 
specifically for the trial.
4.4
Withdrawal Criteria
Withdrawal from Trial
The subjects have the right to withdraw from the trial at any time for any reason, without the need 
to justify their decision. However, the investigator should record the reason for the subject’s 
withdrawal, if possible. 
If, at the time of discontinuation, a dose of the IMP has already been administered, the subject must 
be advised to participate in the follow-up safety investigations, which will include all post-dosing 
antibody assessments and all procedures outlined in the end-of-trial visit.
The investigator also has the right to withdraw subjects. For any discontinuation, the investigator 
will obtain all the required details and document the date of the premature termination and the main 
reason in the e-CRF.
Withdrawal of Consent
If the subject withdraws her consent, no further data will be obtained. However, already obtained 
samples may be analysed. This will be described in the Informed Consent Documents. The subject 
can request destruction of samples which would otherwise have been kept in storage.
4.5
Subject Replacement
A subject can only be assigned one screening number and one randomisation number.
Subjects who discontinue prematurely from the trial after randomisation are not to be replaced, i.e. 
randomisation numbers are uniquely linked to each subject and cannot be re-used.

TREATMENTS
5.1
Investigational Medicinal Products (IMPs)
Subjects will be randomised to the following IMPs in a 1:1 ratio in the trial:

FE 999049 manufactured by Ferring will be provided as a cartridge and an injection pen. 
One subcutaneous injection will be administered daily, starting on day 2-3 of the subject’s 
menstrual cycle and continued throughout the stimulation period. 

GONAL-F (follitropin alfa for injection) manufactured by Merck Serono is provided as a 
pre-filled pen containing a liquid formulation for injection. One subcutaneous injection will 
be administered daily, starting on day 2-3 of the subject’s menstrual cycle and continued 
throughout the stimulation period.
For information on warnings, precautions and treatment of overdose, please refer to the 
Investigator’s Brochure for FE 999049 and the Prescribing Information for GONAL-F.
5.1.1
FE 999049 Dosing Regimen
Subjects randomised to FE 999049 will have their individual dose determined on the basis of their 
AMH level at screening and their body weight at randomisation. For subjects with low AMH 
(<15 pmol/L) the daily FE 999049 dose is 12 μg, irrespective of body weight. For subjects with 
high AMH (≥15 pmol/L) the daily FE 999049 dose is on a continuous scale ranging from 0.19 to 
0.10 μg/kg, i.e. dependent on actual AMH and body weight. The minimum and maximum allowed 
daily doses are 6 µg and 12 µg, respectively. 
The daily FE 999049 dose will be fixed throughout the stimulation period. Dosing will continue 
until the criterion for triggering of final follicular maturation has been met. Subjects can be treated 
with FE 999049 for a maximum of 20 days. Coasting is not allowed. Overdose and medication 
errors of IMP with and without clinical consequences will be tracked in the e-CRF and reviewed 
ongoing by Ferring GPV.
The complete FE 999049 dosing regimen is tabulated in detail in Table 5-1.

AMH concentration will be rounded off to integers.
Subjects can be treated for a maximum of 20 days.
The FE 999049 preparation is administered as a single daily subcutaneous injection in the 
abdomen. The dose must not be split into two injections. To minimise local injection site reactions, 
it is advisable to change injection site regularly.
The first FE 999049 injection will take place at the clinic and will be performed either by the trial 
medication delegate or the subject under supervision by the trial medication delegate. Subsequent 
injections can be done at home or at the clinic. The trial medication delegate will give the subject 
instructions for how to administer FE 999049.
Calculation of the FE 999049 Dose and Setting the Dose on the FE 999049 Pen
The subject’s serum AMH concentration will be available from the blood sample taken at screening 
and analysed by a central laboratory using a qualified assay. The AMH concentration will be 
provided from the central laboratory directly to the e-CRF. The subject’s body weight will be 
measured at randomisation using a calibrated scale and performed without shoes and overcoat. The 
body weight result will be entered into the e-CRF. The FE 999049 dosing algorithm has been 
programmed in the e-CRF, which calculates the FE 999049 dose based on the subject’s AMH and 
body weight. 
The FE 999049 injection pen has a dosing scale numbered from 0 to 24 μg. Each number is 
separated by two lines, each representing 0.33 μg. Thus, the pen can be set to supply doses rounded 
to the nearest 0.33 μg. Rounding off of the calculated dose may be needed, as in this example of a 
subject weighing 60.0 kg with an AMH level of 30 pmol/L for whom the calculated dose is 7.2 μg 
(0.12 μg/kg * 60.0 kg) which will then be rounded to 7.33 μg, i.e. 7 μg + 1 line on the pen. The 
minimum daily dose of 6 µg will be administered in cases like this example: a subject weighing 
40.0 kg and with an AMH level of 40 pmol/L will have a calculated dose of 4.0 µg (0.10 µg/kg * 
40.0 kg) which will then be rounded up to 6 µg. The e-CRF will provide the calculated dose in an 
output that matches the numbers and lines on the injection pen; i.e. any rounding off will be done 
automatically prior to providing the subject’s calculated dose.

5.1.2
GONAL-F Dosing Regimen
For subjects randomised to GONAL-F, the dosing regimen is within labelling. The starting dose of 
GONAL-F is 150 IU per day and fixed for the first five stimulation days, after which it may be 
adjusted by 75 IU per day based on the individual response. The maximum daily GONAL-F dose 
allowed is 450 IU. Dosing will continue until the criterion for triggering of final follicular 
maturation has been met. Subjects can be treated with GONAL-F for a maximum of 20 days.
Coasting is not allowed. Overdose and medication errors of IMP with and without clinical 
consequences will be tracked in the e-CRF and reviewed ongoing by Ferring GPV.
The GONAL-F dosing regimen is shown in detail in Table 5-2.

Conditions for Storage and Use
The trial medication delegate will ensure that the centrally sourced medicinal products will be 
stored in appropriate conditions as stated in the IMP Handling guideline and in a secure location 
with controlled access. The storage compartment shall be monitored regularly and the temperature 
shall be documented.
Deviations in storage temperature must be reported without delay and the centrally sourced 
medicinal products must not be used until further instructions from Ferring are received.
Storage and deviations in storage temperature before dispensing of prescribed CETROTIDE will be 
handled according to standard practice at the hospital / clinic pharmacy and local regulations.
In case of technical malfunction of an administration pen, all relevant details (including time, date, 
a description of the malfunction and whether dosing was affected) of the incidence should be 
reported, the pen should be replaced and the treatment continued.
For information on warnings, precautions and treatment of overdose, please refer to the 
Investigator’s Brochure for FE 999049 and the Product Information for GONAL-F as well as for 
OVITRELLE, GONAPEPTYL, CETROTIDE and CRINONE.
5.6
Blinding / Unblinding
5.6.1
Blinding
The trial is assessor-blind, and all investigators, embryologists and central laboratory personnel will 
be blinded to treatment allocation throughout the trial. The trial medication delegate at site (person 
responsible for IMP/NIMP), the trial coordinator at site (person entering data into e-CRF), the 
monitors and the participating subjects will know the treatment allocation once the subjects are 
randomised. Precaution must be taken to ensure that the treatment allocations are not available to 
the investigators or other assessors throughout the trial. Subjects must be clearly instructed to only 
discuss their treatment allocation with the trial medication delegate, and to not mention it to the 
investigator.
The trial medication delegate will dispense the trial medication to the subject (and may also do the 
actual administration at the clinic, if required). The investigator will, based on the follicular 
development, judge if dose adjustments are recommended and state his/her directions on a form 
developed for that purpose, which will be used to inform the trial medication delegate. Depending 
on whether the subject is being treated with FE 999049 or GONAL-F, the trial medication delegate
will provide detailed instructions to the subject in line with the dosing regimen for each preparation
as outlined in the protocol. In other words, if the investigator recommends a dose adjustment, the 
trial medication delegate will implement a decrease or increase of 75 IU per day as applicable if the 
subject is in the GONAL-F group, while no dose adjustments will be implemented if the subject is
in the FE 999049 group. Requests for cycle cancellation due to inappropriate response or other 
medical reasons are followed, irrespective of treatment group.
The randomisation list will not be available to any person involved in the conduct and evaluation of 
the trial until the trial database is declared clean and locked. Likewise, the treatment allocation 
information in the e-CRF will not be accessible to assessors or the Ferring clinical trial team or 
laboratory personnel during the trial.

The Ferring clinical trial team (i.e. data manager, statistician, trial manager, medical writer, 
pharmacovigilance manager and sponsor’s responsible medical officer) will be blinded to treatment 
allocation until breaking of the blind. The blind will be broken when the trial database is declared 
clean and locked.
5.6.2
Unblinding of Individual Subject Treatment
An emergency unblinding solution will be available to the investigator and designated persons at 
the sponsor. Breaking of the blind for individual subjects in emergency situations is only permitted 
in case of a suspected unexpected serious adverse reaction (SUSAR) or in case of an important 
adverse event where the knowledge of the IMP in question is required for therapeutic decisions for 
the management of the subject.
As far as the emergency permits, the need to break the blind will be agreed by the investigator and 
the sponsor. It should be recorded in the e-CRF that the code is broken, why, when and by whom. 
The investigator must record the event of unblinding in the subject’s medical record, including the 
reason for unblinding.
In case of accidental unblinding (e.g. the subject tells the investigator), the same documentation as 
for emergency unblinding must be obtained, i.e. why, when and by whom must be recorded in the 
e-CRF, and the event must also be recorded in the subject’s medical record.
It may be necessary to unblind an individual subject’s treatment for the purposes of expedited 
reporting to the authorities and/or ethics committees. In that situation, every effort will be made to 
maintain blinding of sponsor personnel involved in data analysis and interpretation. Other 
personnel may be unblinded for SUSARs, including trial site staff as well as staff acting on behalf 
of Ferring.
Information on whether the blind has been broken for any subjects must be collected before the 
database is declared clean and locked.
5.7
Dispensing and Accountability, Return and Destruction
All handling of centrally sourced medicinal products (both IMP and NIMP) will be done by a trial 
medication delegate(s) at the site. Prescribed CETROTIDE will be dispensed to the subject by a 
trial medication delegate or a pharmacist / pharmacist assistant, while all subsequent handling of 
prescribed CETROTIDE will be performed by the trial medication delegate. The trial medication 
delegate will maintain subject dispensing logs, detailing the dates, quantities and batch numbers of 
dispensed and returned IMP and NIMP for each subject. The trial medication delegate will also 
manage the overall drug accountability at the site.
The monitor will verify drug accountability of IMP and NIMP throughout the trial and will 
document any discrepancies.
Concerning destruction, the trial medication delegate at the site must ensure destruction of 
dispensed IMP and NIMP in accordance with local legislation after drug accountability has been 
verified by the monitor and signed off by the trial medication delegate, while non-dispensed IMP 
and NIMP will be returned for destruction as instructed by the Ferring IMP Department.

Stimulation 
6.2.1
Stimulation Day 1 
Subjects will attend the stimulation day 1 visit on day 2-3 of the menstrual cycle.
The following must take place prior to randomisation:

Ensure that the subject is still eligible for participation in the trial

Check those inclusion and exclusion criteria that were not possible during screening 

Body weight [note: this body weight result is used for dose calculation in the FE 999049 
group and should be measured on a trial specific calibrated scale]

Pregnancy test – must be negative

Transvaginal ultrasound of uterus and ovaries (endometrial thickness, ovarian volume, 
number and size of follicles). If a cyst ≥10 mm is observed (functional or not), it should be 
punctured before treatment is initiateda. If the cyst was present at the screening visit, it 
should have been recorded on the medical history form. If the cyst presented between 
screening and stimulation day 1, it should be recorded on the adverse event form.
If the subject fulfils all inclusion and exclusion criteria, she will proceed to randomisation:

Randomisation, i.e. assignment to the lowest available subject number and thereby 
allocation to either FE 999049 or GONAL-F
The following must take place after randomisation but before administration of the first dose of 
IMP (FE 999049 or GONAL-F):

Vital signs (systolic blood pressure, diastolic blood pressure, pulse)

Blood collection for central laboratory analysis of:
-
Clinical chemistry and haematology parameters
-
Endocrine parameters (AMH and treatment panel: FSH, LH, estradiol, progesterone, 
inhibin A and inhibin B)
-
Anti-FSH antibodies
Once the above has been completed, the following must be performed by the trial medication 
delegate. Care must be taken to ensure blinding of the investigator and other assessors.

Dispense IMP according to randomisation and instruct the subject on how to administer the
IMP 

Administer the 1st dose of IMP according to randomisation [administration of IMP takes 
place at the clinic and can be done by either the trial medication delegate or the subject
under supervision by the trial medication delegate]:
                                                                                                                                                
a Treatment can be initiated the same day. If puncture is not possible, randomisation may be postponed to the next 
menstrual cycles, assuming that the cyst will disappear and that the subject fulfils the inclusion criteria.


Hand out the diary to the subject. The subject must be instructed to assess and record local 
tolerability immediately, 30 min and 24 hours after each IMP administration throughout the 
entire stimulation period.
After the first administration of FE 999049 or GONAL-F, the subject must do the following: 

Assessment of local tolerability (recorded in a diary) – the first evaluation of local 
tolerability reactions at the injection site is done immediately after the subcutaneous 
injection of IMP, followed by the second evaluation 30 min after injection of IMP and the 
third evaluation 24 hours after injection of IMP (before the next day’s injection of IMP).
Finally, this must be done before the subject leaves the clinic:

Take precautions in the event that the subject experiences an acute allergic reaction. In the 
first 30 min following the IMP administration, the trial medication delegate (or another 
qualified trial staff) must observe the subject’s general health with emphasis on symptoms 
of an acute allergic reaction. The trial sites are requested to have facilities (i.e. medication, 
equipment and trained staff) and procedures in place for diagnosis and treatment of acute 
allergic reactions.

Recording of use of any concomitant medication

Recording of adverse events
The next visit must be scheduled for stimulation day 6.
6.2.2
Stimulation Day 6 
The following must take place at stimulation day 6:

Transvaginal ultrasound of uterus and ovaries (endometrial thickness, endometrial triple-
layer structure, endometrial echogenicity pattern, number and size of follicles)

Blood collection for central laboratory analysis of:
-
endocrine parameters (treatment panel: FSH, LH, estradiol, progesterone, inhibin A 
and inhibin B) – the blood sample must be drawn at least 8 hours after the latest IMP 
administration

Dispensing of IMP and potential dose adjustment
-
FE 999049: the daily dose is fixed throughout stimulation
-
GONAL-F: from stimulation day 6 and onwards, the daily dose may be adjusted by 
75 IU per day based on the individual response

emphasis on symptoms of an acute allergic reaction. Note: it is important that the subject 
does not mix up the injection sites for IMP and GnRH antagonist

Instruct the subject to administer the GnRH antagonist at a daily dose of 0.25 mg throughout 
the stimulation period.
After the stimulation day 6 visit, the next visits must be scheduled at least every second day 
throughout the remaining stimulation period. When the leading follicle reaches ≥15 mm, visits must 
be performed daily.
6.2.3
Stimulation Days ≥7 to ≤20
These visits will take place at least every second day throughout the remaining stimulation period. 
When the leading follicle reaches ≥15 mm, visits must be performed daily. Coasting is not allowed. 
The maximum period of stimulation is 20 days.
The following must take place at all visits throughout the remainder of the stimulation period (with 
the exception of the end-of-stimulation visit, which is described in section 6.2.4):

Transvaginal ultrasound of uterus and ovaries (endometrial thickness, endometrial triple-
layer structure, endometrial echogenicity pattern, number and size of follicles)

End-of-stimulation
The end-of-stimulation visit takes place when the subject reaches the criterion for triggering of final 
follicular maturation or any of the cycle cancellation criteria because of poor or excessive follicular
development as specified in Table 6-2. Administration of hCG or GnRH agonist must take place as 
soon as reaching the criterion for triggering of final follicular maturation.
If triggering as soon as reaching the criterion would lead to oocyte retrieval or embryo transfer on a 
day the clinic is closed e.g. Sunday or a public holiday, stimulation may be continued for one 
additional day, meaning triggering is delayed for a maximum of one day.

If the GnRH antagonist is administered in the morning it should also be administered on the day of 
triggering. If the GnRH antagonist is administered in the evening, no GnRH antagonist is to be 
given on the day of triggering.
Table 6-2
Triggering and Cycle Cancellation Criteria related to Follicular Development
Poor follicular development 
Triggering criterion 
Excessive follicular development
If it is judged by the investigator 
that ≥3 follicles with a diameter 
≥17 mm cannot be reached, but 
1 or 2 follicles with a diameter 
≥17 mm are observed, the cycle 
may either be cancelled due to 
poor follicular development or 
triggering of final follicular 
maturation is to be induced, as 
judged by the investigator.
Criterion for triggering of final 
follicular maturation:

≥3 follicles with a diameter 
≥17 mm
If <25 follicles with a diameter 
≥12 mm are observed, hCG is 
administered.
In case of >35 follicles with a 
diameter ≥12 mm, the cycle is to
be cancelled.
If 25-35 follicles with a diameter 
≥12 mm are observed, GnRH 
agonist can be administered; 
alternatively the cycle can be 
cancelled.
If 25-35 follicles with a diameter 
≥12 mm are observed, the cycle 
can be cancelled; alternatively 
GnRH agonist can be
administered.
Triggering drug must be 
administered the day the criterion 
is met.
The investigator also has the option of cancelling the cycle for other relevant medical reasons, 
including adverse events and technical malfunctions of the administration pen.
The following must take place at end-of-stimulation visit:

Transvaginal ultrasound of uterus and ovaries (endometrial thickness, endometrial triple-
layer structure, endometrial echogenicity pattern, ovarian volume, number and size of 
follicles)

Blood collection for central laboratory analysis of:
-
clinical chemistry and haematology parameters
-
endocrine parameters (treatment panel: FSH, LH, estradiol, progesterone, inhibin A 
and inhibin B) – the blood sample must be drawn at least 8 hours after the latest 
administration of IMP and GnRH antagonist

TRIAL ASSESSMENTS
7.1
Assessment Related to Primary Endpoint
7.1.1
Ongoing Pregnancy
A transvaginal or abdominal ultrasound of the uterus will be performed 10-11 weeks after transfer. 
Ongoing pregnancy will be defined as at least one intrauterine viable fetus. For ongoing 
pregnancies, the number of intrauterine viable fetuses will be recorded.
7.2
Assessments Related to Secondary Endpoints
7.2.1
βhCG Test
A blood hCG test must be obtained 13-15 days after transfer. If the test is positive according to the 
local laboratory’s reference ranges, this confirms a positive hCG.
7.2.2
Clinical Pregnancy
A transvaginal ultrasound of the uterus will be performed 5-6 weeks after transfer. Clinical 
pregnancy will be defined as at least one gestational sac, either intrauterine or ectopic. The 
inclusion of ectopic pregnancies and the lack of specification of heart beat in the definition of 
clinical pregnancy is in line with the current International Committee Monitoring Assisted 
Reproductive Technologies (ICMART) and World Health Organization (WHO) glossary on ART 
terminology.d,34 For intrauterine and ectopic pregnancies, the number of gestational sacs with fetal 
heart beat as well as without fetal heart beat will be recorded. 
7.2.3
Vital Pregnancy
A transvaginal ultrasound of the uterus will be performed 5-6 weeks after transfer. Vital pregnancy 
will be defined as at least one intrauterine gestational sac with fetal heart beat 5-6 weeks after 
transfer. 
7.2.4
Implantation
Implantation is determined based on the transvaginal ultrasound performed at the clinical 
pregnancy visit. Implantation rate will be defined as the number of gestational sacs 5-6 weeks after 
transfer divided by number of embryos transferred.
7.2.5
Ongoing Implantation
Ongoing implantation is determined based on the ultrasound performed at the ongoing pregnancy 
visit. Ongoing implantation rate will be defined as the number of intrauterine viable fetuses

10-11 weeks after transfer divided by number of embryos transferred.
7.2.6
Extreme Ovarian Response
The number of oocytes retrieved will be counted at the oocyte retrieval visit. Extreme ovarian 
response will be defined as retrieval of <4, ≥15 or ≥20 oocytes.
7.2.7
Early OHSS (including OHSS of Moderate/Severe Grade) and/or Preventive 
Interventions for Early OHSS
Early OHSS is defined as OHSS with onset ≤9 days after triggering of final follicular maturation. 
Classification of grade is according to Golan’s classification system (see section 8.3 for details) and 
all OHSS cases will be graded as mild, moderate or severe. Preventive interventions for early 
OHSS cover cycle cancellation due to excessive ovarian response or triggering of final follicular 
maturation with GnRH agonist.
7.2.8
Cycle Cancellation due to Poor or Excessive Ovarian Response or Embryo Transfer 
Cancellation due to Excessive Ovarian Response / OHSS Risk
The reason for each cycle cancellation will be recorded. Cycle cancellations related to inappropriate 
ovarian response will include poor and excessive follicular development. Cycle cancellation due to 
poor follicular development is implemented when the investigator judges that ≥3 follicles with a 
diameter ≥17 mm cannot be reached by stimulation day 20. Cycle cancellation due to excessive 
follicular development is implemented when >35 follicles with a diameter ≥12 mm are observed
(can also be implemented if there are 25-35 follicles with a diameter ≥12 mm). The reason for each 
embryo transfer cancellation will be recorded. Transfer cancellation due to adverse events such as 
the Medical Dictionary for Regulatory Activities preferred terms (MedDRA PTs) "ovarian 
hyperfunction" and "ovarian hyperstimulation syndrome" and "high progesterone" in subjects with 
embryos available for transfer will be considered as transfer cancellations due to excessive response 
/ OHSS risk.
7.2.9
Number and Size of Follicles during Stimulation
Transvaginal ultrasound will be performed at all visits during the stimulation period to count the 
number of follicles and measure the size of the follicles. Data will be recorded separately for the 
right and left ovary.
7.2.10
Number and Distribution of Oocytes Retrieved
The number of oocytes retrieved will be recorded at the oocyte retrieval visit. The proportion of 
subjects with <4 oocytes (low response), 4-7 oocytes (moderate response), 8-14 oocytes (targeted 
response), 15-19 oocytes (hyperresponse) and ≥20 oocytes (severe hyperresponse) will be 
calculated.
7.2.11
Metaphase II Oocytes

stage will be categorised as germinal vesicle, metaphase I, metaphase II, degenerated or other.
7.2.12
Fertilisation Rate 
The number of pronuclei will be counted on day 1 after oocyte retrieval and recorded as 0, 1, 2 or 
>2. Fertilised oocytes with 2 pronuclei will be regarded as correctly fertilised.
7.2.13
Number and Quality of Embryos on Day 3
Each embryo will be followed closely and formally evaluated on day 3 after oocyte retrieval. The 
quality evaluation will consist of assessment of cleavage stage and embryo morphology parameters 
(number of cells, degree of fragmentation, blastomere uniformity and visual signs of 
multinucleation). 
Cleavage stage will be defined by the number of blastomeres: 1, 2, 3, 4, 5, 6, 7, 8, …. On day 3, it 
will also be possible to indicate the compaction status instead of number of blastomeres.
Degree of fragmentation will be classified as one of the following: 0%, 1-10%, 11-20%, 21-50%, or 
>50% fragmentation, or totally fragmented (no blastomeres recognised).
Blastomere uniformity will be classified as equally sized blastomeres or unequally sized 
blastomeres (largest blastomere >25% larger in average diameter compared to the smallest 
blastomere). 
Visual sign of multinucleation will be evaluated as yes or no.
A good quality embryo is defined as an embryo with ≥6 blastomeres and ≤20% fragmentation, 
without signs of multinucleation.
7.2.14
Circulating Levels of Endocrine Parameters
During treatment, the following panel of endocrine parameters will be evaluated (treatment panel): 
FSH, LH, estradiol, progesterone, inhibin A and inhibin B. 
Blood samples will be drawn at stimulation day 1e, stimulation day 6 and the end-of-stimulation
visit. The sample on stimulation day 1 (baseline) will be collected prior to the first dose of 
FE 999049 or GONAL-F, and samples drawn at stimulation day 6 and the end-of-stimulation visit 
will be collected at least 8 hours after the previous FE 999049, GONAL-F or GnRH antagonist
administration. The samples will be analysed at a central laboratory. The investigator will review 
and evaluate the laboratory results. The Laboratory Report will be signed and dated by the 
investigator.
7.2.15
FSH Population Pharmacokinetics
In addition to the sampling time points mentioned in section 7.2.14, blood samples will also be 
drawn at the oocyte retrieval visit for analysis of FSH. 
Based on the serum FSH samples obtained during the trial, a population pharmacokinetic model 
will be developed to assess the pharmacokinetics of FE 999049 and confirm predictors for FSH

Total Gonadotropin Dose and Number of Stimulation Days
The start and end dates as well as daily dose of IMP will be recorded and used to calculate the total 
FE 999049 or GONAL-F dose administered and the number of stimulation days.
7.2.17
Gonadotropin Dose Adjustments
Investigator-requested decreases and increases of the gonadotropin dose will be captured during the 
stimulation period. 
7.2.18
Adverse Events
Adverse events will be recorded from the signed informed consent for participation in the trial until 
the end-of-trial visit. For each adverse event the following parameters are recorded by the 
investigator on the Adverse Event Log: description of event, date and time of onset, intensity, 
causal relation to IMP, action taken to IMP, other actions taken, seriousness of the adverse event, 
date and time of outcome, and outcome. Furthermore, the pattern (e.g. the frequency, time of onset, 
intensity, seriousness and outcome) of the most frequent / relevant adverse events will be tabulated. 
7.2.19 Clinical Chemistry and Haematology Parameters
The following clinical chemistry and haematology parameters will be analysed at a central 
laboratory: 
CHEM-20: alanine transaminase, albumin, alkaline phosphatase, aspartate aminotransferase, 
bicarbonate, bilirubin direct, bilirubin total, blood urea nitrogen, calcium, chloride, cholesterol total, 
creatinine, gamma-glutamyl transpeptidase, glucose, lactate dehydrogenase, phosphorus,

Complete Blood Count (CBC): red blood cells, red blood cell morphology, white blood cells, white 
blood cell morphology, haemoglobin, haematocrit, mean corpuscular volume, mean corpuscular 
haemoglobin, mean corpuscular haemoglobin concentration, platelets.
Blood samples will be drawn at screening, on stimulation day 1, end-of-stimulation and end-of-
trial. The samples from the screening visit will be used for safety and eligibility evaluation of the 
subject before randomisation. The sample at stimulation day 1 (baseline) must be drawn before the 
first FE 999049 or GONAL-F injection. The investigator will review the laboratory results and 
evaluate and document whether the abnormal results are non-clinically or clinically significant. The 
Laboratory Report will be signed and dated by the investigator.
7.2.20 Injection Site Reactions
Every day throughout the stimulation period, the subjects will assess the local tolerability of 
subcutaneous injections of FE 999049 or GONAL-F at three time points relative to the daily 
administration: immediately after the injection, 30 minutes after the injection and 24 hours after the 
injection. The following injection site reactions will be assessed: redness, pain, itching, swelling

following: none, mild, moderate or severe.
The subject will record the assessments in a diary and the diary data will subsequently be 
transcribed to the e-CRF.
7.2.21 Anti-FSH Antibodies
Blood samples for assessment of anti-FSH antibodies in the individual subjects in the trial will be 
drawn pre-dosing and post-dosing: 

Screening [note: this sample is exclusively used as back-up sample for the anti-drug 
antibody assay development]

Stimulation day 1, prior to dosing (baseline; pre-dosing sample)

5-10 days after the last FE 999049 or GONAL-F dose
This may coincide with the transfer visit. Subjects not reaching transfer must be called in for 
this extra visit.

19-28 days after the last FE 999049 or GONAL-F dose
This may coincide with the βhCG visit. In case of discontinuation before the βhCG visit, 
this assessment should be done at the end-of-trial visit scheduled 19-28 days after the last 
FE 999049 or GONAL-F dose.
Ferring has developed the following assays for evaluating the immunogenicity of FE 999049 or 
GONAL-F:
Assay 1)
A screening immunoassay, assessing the presence in serum of anti-FSH antibodies, 
using a parametric cut-point approach with a 5% false positive rate. 
Assay 2)
A confirmatory immunoassay, confirming or disconfirming the specificity of any 
positive results in assay 1), using a parametric cut-point approach with a 0.1% false 
positive rate.
Assay 3)
A titre immunoassay determining the antibody response titre of any anti-FSH 
antibodies confirmed in assay 2).
Assay 4)
A cell-based assay qualitatively assessing the neutralising capacity of any anti-FSH 
antibodies confirmed in assay 2), using a parametric cut-point approach with a 1% 
false positive rate.
Assay 5)
A cell-based assay determining the neutralising antibody response titre of any 
positive result in assay 4).
Assay 6)
A confirmatory assay based on native FSH, in order to assess cross-reactivity with 
native FSH of any anti-FSH antibodies confirmed to be specific towards exogenous 
FSH in assay 2), using a parametric cut-point approach with a 0.1% false positive 
rate.
In subjects with a negative pre-dosing sample, a treatment-induced anti-FSH antibody response will 
be defined as any post-dosing sample being positive in the confirmatory assay; Assay 2).

In subjects with a positive pre-dosing sample, a treatment-induced anti-FSH antibody response will 
be defined as a statistically determined fold increase in titres from the pre-dosing assessment to a 
post-dosing assessment.f
All positive samples in the confirmatory Assay 2) will be further characterised for titre, neutralising 
capacity (qualitatively and titre) and cross-reactivity. A subject is defined to have treatment-
induced anti-FSH antibodies with neutralising capacity if the subject has a positive outcome of 
assay 4) after IMP administration compared to pre-dose.
The proportion of subjects with treatment-induced anti-FSH antibodies and the proportion of 
subjects with treatment-induced anti-FSH antibodies with neutralising capacity are secondary 
endpoints.
Subjects with a treatment-induced anti-FSH antibody response (both with and without neutralising 
capacity) will be followed until the response becomes negative or has returned to pre-dosing level.
These subjects will be called in for monthly assessments for a period of 3 months after the last post-
dosing anti-FSH antibody sampling. If required, further assessments will be made quarterly, i.e. 6, 9
and 12 months after the last post-dosing anti-FSH antibody sampling. The assessments will be 
terminated when two consecutive assessments are negative or indicate that the pre-dosing level has 
been reached, with a maximum follow-up period of one year. The assessments will also be 
terminated if the subject commences a new treatment cycle with a gonadotropin preparation.
7.2.22
Immune-related Adverse Events
All adverse events reported in the trial will be analysed to identify those that potentially are 
immune-related. To identify all possible cases, a broad-scope search on Standardised Medical 
Dictionary for Regulatory Activities (MedDRA) Queries (SMQs), including ‘Hypersensitivity’,
‘Anaphylactic reactions’, ‘Angioedema’ and ‘Severe cutaneous adverse reactions’ will be 
considered. Moreover, to identify the potential cases manifested by non-specific symptoms and not 
covered by these SMQs, other MedDRA PTs like ‘Musculoskeletal pain’, ‘Asthenia’, ‘Pyrexia’, 
‘Chills’, ‘Body temperature increased’, ‘Influenza like illness’, ‘Injection related reaction’, ‘Pre-
syncope'’ and ‘Syncope’ will also be taken into account. Hypersensitivity reactions manifested by 
local symptoms will be identified using the MedDRA high level term (HLT) ‘injection site 
reactions’. The SMQs may include very specific as well as less specific terms; hence a narrow-
scope search on these SMQs will be carried out to identify those cases that are highly likely to 
represent an immune-related aetiology.
7.2.23
Cycle Cancellations due to an Adverse Event, including Immune-related Adverse 
Events, or due to Technical Malfunctions of the Administration Pen
The reason for each cycle cancellation will be recorded. Among the options are adverse events, 
including immune-related adverse events, and technical malfunctions of the administration pen.

subsequent calculation of ovarian volume. 
7.3.13 Endometrial Status
Transvaginal ultrasound of the uterus to assess the endometrial status will be conducted at all visits 
during the stimulation period. The endometrial status assessments consist of the following 
parameters: endometrial thickness, endometrial triple-layer structure and endometrial echogenicity 
pattern (note: the latter two are not assessed on stimulation day 1).
Endometrial thickness (composed of both layers of the endometrium) will be measured in the 
sagittal view of the uterus from the proximal and distal interfaces between the echogenic 
endometrium and the hypoechoic inner layer of the myometrium. Care should be taken not to 
include the hypoechoic subendometrial halo and to account for the presence of any fluid in the 
uterine cavity (not to be included in the endometrial thickness value). Endometrial thickness will be 
recorded in mm.
Endometrial triple-layer structure will be recorded as observed or not.
Endometrial echogenicity pattern will be recorded as hypoechogenic, isoechogenic, 
hyperechogenic, or not possible to evaluate.

should be recorded. One diagnosis / symptom should be entered per record.
If a subject suffers from the same adverse event more than once and the subject recovers in between 
the events, the adverse events should be recorded separately. If an adverse event changes in 
intensity, a worst-case approach should be used when recording the event, i.e. the highest intensity 
and the longest duration of the event.g
Note: A procedure is not an adverse event; the reason for conducting the procedure is. 
Hospitalisation is not an adverse event; the reason for hospitalisation is. Death is not an adverse 
event, but the cause of death is (an exception is sudden death of unknown cause, which is an 
adverse event).
Date and Time of Onset
The date of onset is the date when the first sign(s) or symptom(s) were first noted. If the adverse 
event is an abnormal clinically significant laboratory test or outcome of an examination, the onset 
date is the date the sample was taken or the examination was performed. 
                                                                                                                                                
g
Exception: if an adverse event with onset before the first IMP administration (i.e. a pre-treatment adverse event) 
changes in intensity after the administration of the IMP, this must be recorded as two separate events. The initial 
adverse event should be recorded with outcome “not yet recovered” and the date and time of outcome is when the 
intensity changed. The second adverse event should be recorded with date and time of onset when the intensity 
changed.

Intensity
The intensity of an adverse event must be 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).
Severe:
Inability to work or perform usual activities (unacceptable).
Causal Relationship to IMP
The possibility of whether the IMP caused the adverse event must be classified as one of the 
following:
Reasonable possibility: 
There is evidence or argument to suggest a causal relationship 
between the IMP and the adverse event. The adverse event may occur 
as part of the pharmacological action of the IMP or may be 
unpredictable in its occurrence.
Examples: 

Adverse events that are uncommon but are known to be strongly 
associated with IMP exposure.

Adverse events that are not commonly associated with IMP 
exposure, but the event occurs in association with other factors 
strongly suggesting causation, such as a strong temporal 
association with the IMP or the event recurs on rechallenge with 
the IMP.
No reasonable possibility: 
There is no reasonable evidence or argument to suggest a causal 
relationship between the IMP and the adverse event.
Examples:

Known consequences of the underlying disease or condition 
under investigation.

Adverse events common in the trial population, which are also 
anticipated to occur with some frequency during the course of the 
trial, regardless of IMP exposure.
Action Taken to IMP
The action taken to the IMP in response to an adverse event must be classified as one of the 
following:

No change (medication schedule maintained or no action taken)

Discontinued

Interrupted

Adverse Events of Special Interest and/or Requiring Special Handling
8.3.1
Ovarian Hyperstimulation Syndrome (OHSS)
Symptoms and Classification
OHSS is an adverse event of special interest during controlled ovarian stimulation. Investigators 
will record OHSS symptoms and use these symptoms directly to grade (1, 2, 3, 4 or 5) each OHSS 
case into Golan’s classification system35 as shown in Table 8-1.

Table 8-1
Classification of Mild, Moderate and Severe OHSS (Golan’s Classification 
System)
Mild OHSS
Grade 1
Abdominal distension and discomfort 
Grade 2 
Features of grade 1 plus nausea/vomiting and/or diarrhoea. Ovaries enlarged to 
5-12 cm.a)
Moderate OHSS
Grade 3 
Features of mild OHSS plus ultrasonic evidence of ascites.b)
Severe OHSS
Grade 4 
Features of moderate OHSS plus clinical evidence of ascites and/or hydrothorax (or 
breathing difficulties). Paracentesis due to OHSS symptoms. c)
Grade 5 
All of the above plus change in blood volume, increased blood viscosity due to 
haemoconcentration, coagulation abnormalities, and diminished renal perfusion and 
function.d) Hospitalisation due to OHSS symptoms.
a) For each ovary, the size will be the average of the greatest diameter and its greatest perpendicular diameter. Ovarian 
enlargement will be based on the average size of the right and left ovaries. The sizes of both ovaries should be 
recorded. 
b) For subjects with transvaginal evidence of ascites, the size of the fluid pockets in the pelvis (Douglas pouch, vesico-
uterine pouch, etc) should be estimated by measuring the greatest diameter and its greatest perpendicular diameter, 
and multiplying these two numbers (the unit will be cm2). Peritoneal fluid is the total size of all fluid pockets in the 
pelvis. 
c) In case of paracentesis, the volume of fluid drained should be measured.
d) Heaemoconcentration is defined as haematocrit >45 %. Electrolyte disturbances is defined as hyponatremia (sodium 
<135 mEq/L) and/or hyperkalemia (potassium >5.0 mEq/L). Coagulation abnormalities are defined as presence of 
thromboembolic events, abnormal prothrombin time or abnormal activated partial thrombin time. Diminished renal 
perfusion is defined as creatinine >1.2 mg/dl. Oliguria is defined as urine output less than 500 mL / 24 hours. Anuria 
is defined as failure to produce urine. If applicable, actual volume of urine output will be recorded.
All cases of OHSS must be reported as adverse events. Those that fall under the category serious 
adverse events must be reported as such. Note that the classification ‘mild OHSS’, ‘moderate 
OHSS’ and ‘severe OHSS’ does not refer to the classification of an adverse event’s intensity (also 
rated mild, moderate, or severe).
Subject narratives will be prepared for all moderate and severe OHSS cases.
Concerning timing, early OHSS will be defined as OHSS with onset ≤9 days after triggering of 
final follicular maturation and late OHSS will be defined as OHSS with onset >9 days after 
triggering of final follicular maturation.
In addition to early OHSS and late OHSS overall, emphasis will be placed on OHSS of 
moderate/severe grade.
Preventive Interventions of Early OHSS
Preventive interventions of early OHSS include the following:

Cycle cancellation due to excessive ovarian response

Investigations to be Conducted in Subjects where OHSS Symptoms are Observed
The following investigations must be conducted when OHSS symptoms are first observed and 
repeated when there are clinically relevant changes in the OHSS presentation: 

Body weight and maximum abdominal circumference (for all OHSS)

Vital signs (for all OHSS)

Blood sample for central laboratory analysis of the following (for moderate/severe OHSS):

Progesterone and estradiol

CBC (red blood cells, red blood cell morphology, white blood cells, white blood cell 
morphology, haemoglobin, haematocrit, mean corpuscular volume, mean 
corpuscular haemoglobin, mean corpuscular haemoglobin concentration, platelets)

CHEM-20 (alanine transaminase, albumin, alkaline phosphatase, aspartate 
aminotransferase, bicarbonate, bilirubin direct, bilirubin total, blood urea nitrogen, 
calcium, chloride, cholesterol total, creatinine, gamma-glutamyl transpeptidase, 
glucose, lactate dehydrogenase, phosphorus, potassium, sodium, total protein, uric 
acid)

Coagulation parameters (prothrombin time, activated partial thrombin time)
Any treatments of OHSS, e.g. intravenous administration of volume expanders, paracentesis, use of 
low-molecular-weight heparin and intravenous administration of albumin, must be recorded as 
concomitant medication.
8.3.2
Local Tolerability
Injection site reactions after administration of IMP (FE 999049 and GONAL-F) are only to be 
reported as adverse events if they require active management, i.e. discontinuation of IMP, 
additional investigations or treatment of the injection site reaction. Local tolerability of IMP 
constitutes a secondary endpoint and will be evaluated in detail based on the subjects’ recordings in 
the diary. 
Local tolerability reactions after administration of NIMP are to be reported as adverse events if they 
fulfil the definition of an adverse event.
8.3.3
Treatment-induced Anti-FSH Antibodies
Presence of treatment-induced anti-FSH antibodies is not to be reported as an adverse event. These 
data will be described as part of the secondary endpoints.

Menstrual Bleeding
Menstrual bleeding is only to be reported as an adverse event in case it is excessive, painful, 
delayed or in any other way deviating from the subject’s normal menstruation. Menstrual bleeding 
associated with lack of pregnancy will be reported as part of the efficacy evaluation.
8.3.5
Ovarian Torsion
Any case of ovarian torsion will be reported as an adverse event and it will be specified whether it 
is associated with any signs or symptoms of OHSS.
8.3.6
Pregnancy Losses
The following terminology should be used for reporting of pregnancy losses during the trial:
Biochemical pregnancy: 
Positive βhCG test but no gestational sac is observed on later 
transvaginal ultrasound, or menstruation is reported
Spontaneous abortion: 
Positive βhCG test but all intrauterine gestational sacs are 
without fetal heart beat as documented by ultrasound, or there 
are no viable fetuses observed by ultrasound
Vanishing twin:
Spontaneous disappearance of an intrauterine gestational sac 
with or without heart beat in a pregnancy where one viable 
fetus remains as documented by ultrasound
Ectopic pregnancy:
Extrauterine gestational sac with or without fetal heart beat as 
documented by ultrasound or surgery
Concerning timing, a pregnancy loss occurring before ongoing pregnancy (i.e. during 1st trimester) 
will be defined as an early pregnancy loss, while a pregnancy loss occurring after ongoing 
pregnancy (i.e. during 2nd or 3rd trimester) during the post-trial follow-up will be defined as a late 
pregnancy loss.
8.3.7
Multiple Pregnancies
Multi-fetal gestations are not to be reported as adverse events. These data will be described as part 
of the secondary endpoints.

Serious Adverse Events
8.4.1
Serious Adverse Event Definition
Serious Adverse Events during the Trial
An event is defined a serious 
adverse event if it:
Guidance
results in death
Any event resulting in a fatal outcome must be fully documented and reported, 
including deaths occurring within four weeks after the treatment ends and 
irrespective of the causal relationship to the IMP. The death of a subject 
enrolled in a trial is per se not an event, but an outcome.
is life-threatening
The term life-threatening refers to an adverse event in which the subject was at 
immediate risk of death at the time of the event. It does not refer to an event, 
which may have caused death if it were more severe.
requires in-patient
hospitalisation or prolongation 
of existing hospitalisation
The term hospitalisation means that the subject was admitted to hospital or that 
existing hospitalisation was extended as a result of an event. Hospitalisation 
describes a period of at least 24 hours. Over-night stay for observation, stay 
at emergency room or treatment on an out-patient basis do not constitute a 
hospitalisation. However, medical judgement must always be exercised and 
when in doubt the case should be considered serious (i.e. if case fulfils the 
criterion for a medically important event). Hospitalisations for administrative 
or social purposes do not constitute a serious adverse event. Hospital 
admissions and/or surgical operations planned before trial inclusion are not 
considered adverse events, if the illness or disease existed before the subject 
was enrolled in the trial, provided that the condition did not deteriorate during 
the trial.
results in persistent or 
significant disability /
incapacity
Disability / incapacity means a substantial disruption of a person’s ability to 
conduct normal life functions. In doubt, the decision should be left to medical 
judgement by the investigator.
is an important medical event
Medical and scientific judgment should be exercised in deciding whether other 
situations should be considered serious such as important medical events that 
might not be immediately life-threatening or result in death or hospitalisation 
but might jeopardise the patient or might require intervention to prevent one of 
the other outcomes listed in the definition above. Examples of such events are 
intensive treatment in an emergency room or at home for allergic 
bronchospasm, blood dyscrasias or convulsions that do not result in 
hospitalisation, or development of drug dependency or drug abuse.
Serious Adverse Events during Post-trial Follow-up
The following untoward medical occurrences reported as part of the pregnancy outcome and 
neonatal health data collection will be recorded as serious adverse events. Data will be collected at 
birth and at 4 weeks after birth.

Death of mother in connection with pregnancy or labour

Death of neonate


Medically important event
In case of admission to NICU or NCU, the reason for admission must be reported as a serious 
adverse event, rather than just the act of hospitalisation. 
Congenital anomalies will be coded by Ferring using both MedDRA and ICD-10 and classified as 
minor or majorh in accordance with the EMA guideline1.

Collection, Recording and Reporting of Serious Adverse Events
Serious Adverse Event Reporting by the Investigator
All serious adverse events must be reported immediately to Ferring Global Pharmacovigilance as 
soon as it becomes known to the investigator and not later than within 24 hours of their knowledge 
of the occurrence of a serious adverse event.
The investigator is responsible for submitting the completed Serious Adverse Event (SAE) Report 
Form with the fullest possible details within 3 calendar days of his/her knowledge of the serious 
adverse event.
Serious Adverse Event (SAE) Report Form
The SAE Report Form is included in the e-CRF system, and must be completed and submitted 
according to the instructions provided on the form. In case the e-CRF cannot be accessed and hence

Additional information relevant to the serious adverse event such as hospital records, results from 
investigations, e.g. laboratory parameters (that are not already uploaded in the e-CRF), invasive 
procedures, scans and x-rays, and autopsy results can be faxed or scanned and e-mailed to Ferring 
Global Pharmacovigilance using the contact details in the section above. In any case this 
information must be supplied by the investigator upon request from Ferring. On any copies 
provided, such details such as subject’s name, address, and hospital ID number should be concealed 
and instead subject number should be provided.
The investigator will supply Ferring and the ethics committee with any additional requested 
information such as results of post-mortem examinations and hospital records.
Expedited Reporting by Ferring
Ferring will report all adverse events that are serious, unexpected and with a reasonable possible 
causality to the IMP as judged by either the investigator or Ferring to the relevant parties within 
the stipulated timelines.
The expectedness is assessed by Ferring according to the current edition of the Investigator’s 
Brochure for FE 999049 and the Product Information for GONAL-F.4
Serious adverse events will be considered reportable regardless of whether or not the IMP was used 
in accordance with the provisions in the protocol, Investigator’s Brochure and labelling.
8.5
Follow-up of Adverse Events and Serious Adverse Events 
8.5.1
Follow-up of Adverse Events with Onset during the Trial
During the trial, the investigator must follow-up on each adverse event until it is resolved or until 
the medical condition of the subject is stable.
After the subject’s last visit, the investigator must follow-up on any adverse event classified as 
serious or considered to have a reasonable possible causality to the IMP until it is resolved or until 
the medical condition of the subject is stable. All such relevant follow-up information must be 
reported to Ferring. If the event is a chronic condition, the investigator and Ferring may agree that 
further follow-up is not required.
8.5.2
Collection of Serious Adverse Events with Onset after End-of-trial
If an investigator becomes aware of a serious adverse event after the end of the trial, and he/she 
assesses the serious adverse event to have a reasonable possible causality to the IMP (FE 999049 or 
GONAL-F) or a NIMP where Ferring is Marketing Authorisation Holder (i.e. GONAPEPTYL) the 
case will have to be reported to Ferring, regardless how long after the end of the trial this takes 
place.

STATISTICAL METHODS
The Ferring Global Biometrics Department will be responsible for the statistical analyses of the 
primary and secondary endpoints. This section details the planned statistical analyses for the 
primary endpoint and outlines the planned statistical analyses for the secondary endpoints. All 
analyses and further descriptions of the statistical methodology for the primary and secondary 
endpoints will be included in the Statistical Analysis Plan (SAP) available before the first subject is 
randomised. A separate SAP will be prepared to cover the post-trial information.
The Ferring Health Economics & Outcome Research department will perform a health economic 
analysis of FE 999049 in comparison with GONAL-F utilising relevant data recorded in this trial. 
The details of this analysis will be described in a separate health economic analysis plan.
9.1
Determination of Sample Size
The primary objective of this trial is to demonstrate non-inferiority of FE 999049 compared with 
GONAL-F with respect to ongoing pregnancy rate in women undergoing controlled ovarian 
stimulation. The non-inferiority limit for the difference between treatments (FE 999049 versus
GONAL-F) is -10.0% (absolute) for the primary endpoint.
The trial is designed to have 90% power of achieving the primary objective for the overall trial 
population and 80% power in the mainland Chinese population. The number of subjects needed to 
achieve 90% power depends on the assumptions regarding the ongoing pregnancy rate. The 
ongoing pregnancy rate is defined as the number of subjects with at least one intrauterine viable 
fetus 10-11 weeks after transfer divided by the number of randomised and exposed subjects. 
Considerations for Choice of Non-inferiority Margin
Assuming that the ongoing pregnancy rate is 32.2% in both treatment groups, then the total number 
of subjects needed to achieve 90% power is governed by the choice of non-inferiority margin. In 
order to establish non-inferiority, the two-sided 95% confidence interval must lie entirely above the 
chosen non-inferiority margin. Therefore, the power of the test is directly related to the width of the 
two-sided 95% confidence interval. The width of this confidence interval is inversely related to the 
square root of the sample size, i.e. a quadrupling of the sample size will lead to a halving of the 
width of the confidence interval. In fact, increasing the sample size with 500 subjects from 100 to 
600 reduces the width of the confidence band with 59%, while the impact of a similar increase in 
number of subjects from 1,000 to 1,500 only reduces the width of the confidence band with 18%.
The sample sizes for three different non-inferiority margins are shown in Table 9-1. As shown,
changing the non-inferiority margin from -12.0% to -10.0% requires 280 additional subjects, while 
tightening the margin with an additional 2.0% requires 516 additional subjects. To further illustrate 
the difference between these three non-inferiority margins, the width of the two-sided 95% 
confidence intervals and the precision quantified as ±1 standard error are also included in 
Table 9-1. As can be seen, increasing the sample size from 918 to 1,434 subjects reduces the 
standard error with 0.6 percentage points (from 3.1% to 2.5%).

The relation between the choice of non-inferiority margin and the maximum allowed difference in 
ongoing pregnancy rates leading to non-inferiority can also be derived. Assuming the observed rate 
for the GONAL-F group is 32.2% the minimum observed rate in the FE 999049 group that still 
leads to non-inferiority is shown in Table 9-1. For example, if the non-inferiority margin is -10.0% 
and the observed ongoing pregnancy rate in the GONAL-F group is 32.2%, then non-inferiority 
will only be established if the observed ongoing pregnancy rate in the FE 999049 group is at least 
28.2%, i.e. the observed ongoing pregnancy rates must not differ with more than 4.0 percentage 
points. Tightening the margin to -8.0%, (i.e. adding 516 subjects) will require a minimum ongoing 
pregnancy rate of 29.0% in the FE 999049 in order to claim non-inferiority, i.e. a maximum 
difference of 3.2 percentage points. Hence, increasing the sample size from 918 to 1,436 subjects 
reduces the maximum allowable observed difference between treatments by 0.8 percentage points 
(from 4.0% to 3.2%).
Taking the above into account a non-inferiority margin of -10.0% (absolute) seems appropriate 
since further tightening of the non-inferiority margin will lead to an increase in sample size with 
only limited impact on the precision of the estimate and the maximum difference in observed rates 
leading to non-inferiority.

Considerations for Sample Size
Table 9-2 summarises the required sample size to obtain 80% and 90% power for various rates 
(assumed equal in the two treatment groups) and assuming a non-inferiority margin of -10.0% 
(absolute).
Since this is a non-inferiority trial, the full analysis set (FAS) and the per-protocol (PP) analyses are 
equally important, i.e. non-inferiority should be established for both analysis sets in order to have a 
robust conclusion36,37. Therefore, the expected proportion of subjects with major protocol deviations 
should be taken into account when setting the total sample size for the trial. The proportion of 
subjects with major protocol deviations is assumed to be at most 8%.

* Assuming 8% major protocol deviations
Based on an assumed ongoing pregnancy rate of 32.2 % observed in the PP population of the 
ESTHER 1 trial, N=918 subjects are required in the PP population to obtain a power of 90%. 
Anticipating at most 8% major protocol deviations this results in N=1000 subjects to be 
randomised. The power is reasonably robust against deviations from the ongoing pregnancy rate 
assumption of 32.2%: a 35% ongoing pregnancy rate would still result in a 88.9% power, while 
lower rates will only increase the power (e.g. 30% yields 91.1% power). Recruiting at least 
740 subjects in mainland China is expected to secure that consistency can be established between 
the results from the overall trial population and the mainland Chinese trial population. In addition, 
to obtain approval in other Asian countries and regions at least 260 subjects are needed. Thus a total 
sample size of 1,000 subjects will be recruited for this trial.
A sample size re-assessment is planned and will be done without breaking the blind and without 
inflating the type 1 error of the trial, in line with the current regulatory guidelines (see section 9.10). 
The expected maximum number of subjects to be randomised would then be approximately 1,144
(572 per treatment group), corresponding to an observed rate of 50%. 
9.2
Subject Disposition
All screened subjects will be accounted for. 
Screened subjects who discontinue from the trial prior to randomisation are regarded as screening 
failures.
Subject disposition with respect to analysis sets will be tabulated by treatment group overall, by age 
stratum and country for all randomised subjects. This table will include the number of completed 
and discontinued subjects including reason for discontinuation. Screening failures and their primary 
reason for screening failure will also be included. Screening failures will not otherwise be 
accounted for. 
A separate table will summarise the subject disposition with respect to analysis sets by trial site 
overall and by age stratum.

Protocol Deviations
Major protocol deviations, such as significant non-compliance or other serious unforeseen
deviations deemed to invalidate the data and affect the conclusions of the trial, will lead to
exclusion of data from the PP analysis set. Data will not be excluded from the PP analysis set in
case of minor protocol deviations. The list of major protocol deviations include, but is not restricted 
to:

Unblinding of assessor

Treatment not in accordance with randomisation

Non-compliance with IMP for two or more days

Administration of hCG for triggering of final follicular maturation was not given despite the
triggering criterion for hCG administration was met

GnRH agonist criterion met but hCG used for triggering of final follicular maturation

GnRH agonist criterion not met but GnRH agonist used for triggering of final follicular 
maturation

Non-compliance with the number of embryos transferred
The rating of protocol deviations in ‘minor’ and ‘major’ will be decided by the Ferring clinical
team on the basis of a blinded review of data before declaration of clean file and lock of database. If 
the blinded review identifies serious unforeseen deviations deemed to impact the primary endpoint 
and affect the conclusions of the trial these will also be rated as major deviations. 
The list of major protocol deviations will be detailed and documented in the clean file document 
prior to database release. Major protocol deviations will be tabulated and listed by subject for the 
FAS analysis set.

Endpoint Assessments
9.7.1
General Considerations
Primary and Secondary Endpoints
The results of the analyses of the primary endpoint (ongoing pregnancy rate) based on the overall 
trial population are essential for the non-inferiority claim. The results obtained for the mainland 
Chinese trial population is considered supportive of the overall conclusion. If the results for the 
mainland Chinese trial population are markedly different from those obtained based on the overall 
trial population the reasons for this difference will be examined. The secondary endpoints positive 
βhCG rate, clinical pregnancy rate, vital pregnancy rate, implantation rate and ongoing implantation 
rate are considered supportive of the primary endpoint. However, non-inferiority does not need to 
be established for these secondary endpoints.
The remainder of the secondary endpoints are intended to provide additional characterisation of the 
treatments. 
Analysis and Presentation of Primary and Secondary Endpoints
Summary tables and treatment comparisons for the primary endpoint and supportive secondary 
endpoints will be presented overall, by age stratum and country for both the FAS and PP analysis 
sets. Treatment comparisons will be produced for the overall trial population and for the mainland 
Chinese population. As applicable for the remaining secondary endpoints, summary tables and 
treatment comparisons may be presented overall and by age stratum for the FAS and PP analysis 
sets. 
All tabulations will present the treatment groups and include a total column. Continuous variables 
will be presented with number of subjects, mean, standard deviation, median, inter-quartile range, 
minimum, and maximum. Categorical variables will be presented with number and percentage of 
subjects within each specific category. 
All statistical tests will be performed using a two-sided test at a 5% significance level. Treatment 
differences will (where appropriate) be presented with 95% confidence intervals and p-values 
corresponding to the statistical test of the hypothesis of ‘equal effect’ against the alternative of 
‘different effect’.
Visual displays will be produced as appropriate. All primary and secondary efficacy endpoints will 
be listed for the FAS.
Multiplicity 
No adjustments for multiplicity are required since there is only one primary endpoint and non-
inferiority has to be established for both the FAS and the PP analysis sets. In addition, the testing 
for superiority will be made in a sequential manner, only if non-inferiority is established. The 
evaluation of the subjects recruited in mainland China will be regarded as supportive. Concerning 
the secondary endpoints no formal adjustment for multiplicity will be utilised.

Missing Data
Missing observations for the primary endpoint ongoing pregnancy rate will be imputed as 
‘negative’ irrespective of the reason why data are not recorded.
Missing observations for the supportive secondary endpoints positive βhCG rate, clinical pregnancy 
rate and vital pregnancy rate will be imputed as ‘negative’ unless a positive result is observed at a 
later pregnancy assessment. For example, if the outcome of βhCG is missing but clinical pregnancy 
is positive then βhCG will be imputed as ‘positive’.
For subjects with transfer but missing information on the number of viable fetuses 10-11 weeks 
after transfer, the number of viable fetuses will be imputed as zero irrespective of why data are not 
recorded. For subjects with transfer but missing information on the number of gestational sacs 
5-6 weeks after transfer, the number of gestational sacs will be imputed as the number of viable 
fetuses at 10-11 weeks after transfer.
For adverse events, missing values will be treated as missing, except for causality, intensity and
seriousness of adverse events, where a worst-case approach will be used.
Missing values will not be imputed for any of the other secondary endpoints.
9.7.2
Primary Endpoint
This trial has one primary endpoint: Ongoing pregnancy rate. The primary objective of this trial is 
to demonstrate non-inferiority of FE 999049 compared with GONAL-F with respect to the primary 
endpoint in women undergoing controlled ovarian stimulation. The non-inferiority limit for the 
difference between treatments (FE 999049 versus GONAL-F) is -10.0% (absolute).
The non-inferiority hypothesis to be tested for the primary endpoint is
H0: FE - GF -10.0% against the alternative HA: FE - GF > -10.0%,
where FE and GF denote the ongoing pregnancy rate after treatment with FE 999049 and 
GONAL-F, respectively. Non-inferiority will be evaluated based on the overall trial population.
The primary analyses will be adjusted for the stratification factor (age group) by using the Mantel-
Haenszel method to combine results across age groups. In brief, this corresponds to deriving a 
weighted average across age groups where the weight depends on the number of observations in 
each treatment group in each age stratum.
For the primary endpoint the null hypothesis (H0) will be tested against the alternative (HA) by 
constructing a two-sided 95% confidence interval for the difference in ongoing pregnancy rates. If 
the lower-limit of the two-sided 95% confidence interval is greater than the non-inferiority limit 
(-10.0%) for both the FAS and the PP analysis set, the null hypothesis will be rejected. In that case 
it will be claimed that FE 999049 is non-inferior to GONAL-F with respect to ongoing pregnancy 
rate in women undergoing controlled ovarian stimulation.

If the lower-limit of the two-sided 95% confidence interval for the treatment difference based on 
the FAS not only lies above the non-inferiority limit (-10.0%) but also above zero then there is 
evidence of superiority in terms of statistical significance at the 5% level. In this case, the p-value 
from the test for superiority will be reported and it will be claimed that FE 999049 is superior to 
GONAL-F for the primary endpoint analysed. The result based on the PP analysis set is not 
essential for the superiority claim but should lead to a comparable result for a robust interpretation. 
There is no need for a multiplicity adjustment when switching from non-inferiority to superiority 
since it is a simple sequential test procedure. This interpretation is in line with the Food and Drug 
Administration (FDA) draft guidance on “Non-inferiority Clinical Trials”36 and EMA’s “Points to 
consider on switching between superiority and non-inferiority”38.
Due to the large sample size the two-sided 95% confidence intervals will be established based on 
the asymptotic normal distribution as follows

A supportive evaluation of the subjects recruited in mainland China will be conducted, and it is 
expected that the findings among the mainland Chinese trial population will be consistent with the 
overall findings in the trial. If the results based on the mainland Chinese trial population are 
markedly different from those obtained based on the overall trial population the implications for the 
overall conclusion of the trial will be evaluated.

Additional Analyses, including Sensitivity Analysis
The primary analyses described above will be repeated restricted to subjects with oocytes retrieved 
and to subjects with embryo(s) transferred. Since the trial is not powered to establish non-inferiority 
for these subgroups, the outcomes of these analyses are considered supportive of the primary 
analysis.
Besides stratification by age group the randomisation is also stratified by trial site. However, as 
detailed above, the primary analysis will be based on all data pooled across sites assuming 
homogeneity of the risk differences across sites. This assumption will be tested using the approach 
described by Lipsitz et al. (1998).39 If there is statistically significant heterogeneity across sites the 
implications for the interpretation of the primary result will be discussed.
To evaluate the robustness of the conclusions, the following factors potentially impacting ongoing 
pregnancy will be evaluated one by one:

Insemination method

Primary reason for infertility

Primary infertility

Smoking status
For each factor, subjects will be grouped according to the levels of the factor and the primary 
analysis will be repeated using this grouping. The outcomes of these analyses are considered 
supportive and should lead to similar results as the primary analysis to ensure robustness of the 
conclusion.
As described in Section 6.5.1, transfer of one or two embryo(s) is to be performed on day 3 after 
oocyte retrieval. The decision to transfer either one or two embryo(s) is based on the subject’s age 
and the quality and availability of embryo(s) on the day of transfer. Since this decision is based on 
observations performed after randomisation it can be affected by the treatment allocation. It is 
therefore not planned to perform a formal statistical analysis of the ongoing pregnancy rate
adjusting for number of embryos transferred. The rationale for not including these adjustments in 
the primary analysis is that such an adjustment may hide or exaggerate the differences between 
treatments.40 Instead the ongoing pregnancy rate will be presented by number of embryos
transferred. Further, a frequency table will be produced to compare the treatment groups with 
respect to number of embryos transferred.
9.7.3
Secondary Endpoints
For each secondary endpoint the analysis based on the FAS will be used to assess the statistical 
significance of differences between treatments. The analysis based on the PP analysis set will be 
considered supportive and should lead to a similar but not necessarily statistically significant result 
in order to have a robust interpretation.

Positive βhCG Rate
The positive βhCG rate is considered supportive of the primary endpoint and will therefore be 
analysed in a similar manner.
Clinical Pregnancy Rate
The clinical pregnancy rate is considered supportive of the primary endpoint and will therefore be 
analysed in a similar manner. For subjects with clinical pregnancy, the type of clinical pregnancy 
(intrauterine or ectopic) will be tabulated.
Vital Pregnancy Rate
The vital pregnancy rate is considered supportive of the primary endpoint and will therefore be 
analysed in a similar manner. For subjects with a vital pregnancy, the number of intrauterine 
gestational sacs with fetal heart beat and the number of fetuses with fetal heart beat will be 
tabulated.
Implantation Rate
For implantation rate, the experimental unit will be the transferred embryos, i.e. the analysis will 
compare the proportions of embryos transferred that results in gestational sacs 5-6 weeks after 
transfer.
Ongoing Implantation Rate
For ongoing implantation rate, the experimental unit will be the transferred embryos, i.e. the 
analysis will compare the proportions of embryos transferred that results in intrauterine viable 
fetuses 10-11 weeks after transfer.
Extreme Ovarian Response
The analyses of extreme ovarian response will be performed using the following definitions of 
extreme ovarian response: <4 oocytes retrieved, ≥15 oocytes retrieved, ≥20 oocytes retrieved, <4 or 
≥15 oocytes retrieved and <4 or ≥20 oocytes retrieved. Subjects with cycle cancellation due to poor 
ovarian response will be included as <4 oocytes retrieved. Subjects with cycle cancellation due to 
excessive ovarian response will be included as ≥15 and ≥20 oocytes retrieved.
For each definition the proportion of subjects with extreme ovarian response will be tabulated. 
Treatment groups will be compared using a logistic regression model with treatment and age group 
as factors. The possibility of an interaction will be tested. The difference between treatments will be 
reported as an odds ratio including 95% confidence interval and p-value for test of no treatment 
difference. If the expected number of observations is less than five in any of the cells in the 
contingency table then Fisher’s exact test within strata will be used as alternative.

Early OHSS (Including OHSS of Moderate/Severe Grade) and/or Preventive Interventions 
for Early OHSS
OHSS will for each treatment group be tabulated by classification (mild, moderate, severe) and 
grade (1, 2, 3, 4, 5). Early OHSS is defined as OHSS with onset ≤9 days after triggering of final 
follicular maturation. Note that this includes OHSS with onset before triggering and OHSS with 
onset during stimulation where triggering is not performed.
This endpoint will be tabulated and analysed in a similar manner as the proportion of subjects with 
extreme ovarian response. The analysis will be performed for the proportion of subjects with early 
OHSS, the proportion of subjects with early OHSS of moderate or severe grade, the proportion of 
subjects with preventive interventions for early OHSS, the proportion of subjects with early OHSS 
and/or preventive interventions for early OHSS, and the proportion of subjects with early OHSS of 
moderate or severe grade and/or preventive interventions for early OHSS.
Cycle Cancellation due to Poor or Excessive Ovarian Response or Embryo Transfer 
Cancellation due to Excessive Ovarian Response / OHSS Risk
This endpoint will be tabulated and analysed in a similar manner as the proportion of subjects with 
extreme ovarian response. The analysis will be performed for the following: the proportion of 
subjects with cycle cancellation due to poor ovarian response, the proportion of subjects with cycle 
cancellation due to excessive ovarian response, the proportion of subjects with cycle cancellation 
due to poor or excessive ovarian response, the proportion of subjects with embryo transfer 
cancellation due to excessive ovarian response / OHSS risk.
Number and Size of Follicles during Stimulation 
The follicle cohort on stimulation day 6 and end-of-stimulation will be summarised by treatment on 
the follicle level (number of follicles 8-9 mm, 10-11 mm, 12-14 mm, 15-16 mm and ≥17 mm) and 
on the subject level (total number of follicles, size of largest follicle, average follicle size, average 
size of three largest follicles, and number of follicles ≥8 mm, ≥10 mm, ≥12 mm, ≥15 mm and 
≥17 mm). Continuous data will be compared between treatment groups using the van Elteren test 
stratified for age-group. Ordinal data will be compared using the Cochran-Mantel-Haenszel test for 
ordinal data stratified for age-group. Within strata comparisons will be based on Wilcoxon’s test.
Number and Size Distribution of Oocytes Retrieved
The number of oocytes retrieved will be tabulated including both summary statistics and a 
frequency table with subjects grouped according to number of oocytes retrieved [<4 (low response), 
4-7 (moderate response), 8-14 (targeted response), 15-19 (hyperresponse) and ≥20 (severe 
hyperresponse)]. Subjects with cycle cancellation due to poor ovarian response will be included in 
the <4 oocytes group. Subjects with cycle cancellation due to excessive ovarian response will be 
included in the ≥20 oocytes group. Continuous data will be compared between treatment groups 
using the van Elteren test stratified for age-group. Ordinal data will be compared using the

Metaphase II Oocytes
Oocytes undergoing ICSI will have their maturity stage assessed prior to insemination. The 
percentage of MII oocytes to oocytes retrieved for subjects where all oocytes are inseminated using 
ICSI will be tabulated. Further, the number of MII oocytes per subject will be tabulated including 
both summary statistics and a frequency table. Continuous data will be compared between

using the Cochran-Mantel-Haenszel test for ordinal data stratified for age-group. Within strata 
comparisons will be based on Wilcoxon’s test.
Fertilisation Rate
An oocyte is defined as fertilised if it is scored as 2 pronuclei on day 1 after oocyte retrieval. For
subjects with oocytes retrieved, the rate of fertilised oocytes to oocytes retrieved (and also the rate 
of fertilised oocytes to metaphase II oocytes for those inseminated using ICSI) will be tabulated. 
Further, the number of fertilised oocytes per subject will be tabulated including both summary 
statistics and a frequency table. Continuous data will be compared between treatment groups using
the van Elteren test stratified for age-group. Ordinal data will be compared using the Cochran-
Mantel-Haenszel test for ordinal data stratified for age-group. Within strata comparisons will be 
based on Wilcoxon’s test.
Number and Quality of Embryos on Day 3
The number of embryos on day 3 including a breakdown by selected quality parameters will be 
tabulated including both summary statistics and frequency tables. Further, for subjects with oocytes 
retrieved, the rate of embryos to oocytes retrieved will be summarised overall and by selected 
quality parameters. Continuous data will be compared between treatment groups using the van 
Elteren test stratified for age-group. Ordinal data will be compared using the Cochran-Mantel-
Haenszel test for ordinal data stratified for age-group. Within strata comparisons will be based on 
Wilcoxon’s test.
Circulating Levels of Endocrine Parameters
Blood samples drawn at stimulation days 1 and 6 and end-of-stimulation are analysed for FSH, LH, 
estradiol, progesterone, inhibin A and inhibin B. Furthermore, blood samples drawn at the oocyte 
retrieval visit are also analysed for FSH. Values below the lower limit of quantification (LLOQ) 
will be included as LLOQ/2. Values above the upper limit of quantification (ULOQ) will be 
included as ULOQ.

between treatment groups. These endpoints will be compared between treatments using Wilcoxon’s 
test.
Gonadotropin Dose Adjustments
Investigator-requested decreases and increases of the gonadotropin dose will be captured during the 
stimulation period. The requested dose change (decrease / increase / no change) on stimulation 
day 6 will be tabulated. Further, the number of dose increase requests and number of dose decrease 
requests per subject will be tabulated. Treatment groups will be compared using chi-square tests.
Adverse Events
Adverse Events – General 
Adverse events will be coded using MedDRA. The version of MedDRA will be documented. 
Adverse events are grouped according to start of IMP as follows:

Pre-treatment adverse event, i.e. any adverse event occurring after signed informed consent 
and before start of IMP, or a pre-existing medical condition that worsens in intensity after 
signed informed consent but before start of IMP.

Treatment-emergent adverse event, i.e. any adverse event occurring after start of IMP and 
before the end-of-trial visit, or a pre-treatment adverse event or pre-existing medical 
condition that worsens in intensity after start of IMP and before the end-of-trial visit.

Treatment-emergent adverse events will be presented in summary tables and listings. Pre-treatment 
adverse events will be presented in a listing only.
A treatment-emergent adverse event overview table will be prepared including the number of 
subjects reporting an adverse event, the percentage of subjects with an adverse event, and the 
number of events reported, for the following categories: all adverse events, severe adverse events, 
adverse reactions, adverse events leading to discontinuation, serious adverse events and deaths. An 
adverse reaction is an adverse event judged by the investigator to be related to IMP with a 
reasonable possibility.
Treatment-emergent adverse events will be tabulated by system organ class (SOC) alphabetically 
and preferred term (PT) in decreasing order of frequency. The following will be presented: number 
of subjects reporting an adverse event, the percentage of subjects with an adverse event, and the 
number of events reported.
Summary tables will be produced for the following: all adverse events, adverse events by causality 
(reasonable possibility / no reasonable possibility), adverse events leading to death, adverse events 
by intensity (mild / moderate / severe), adverse reactions by intensity (mild / moderate / severe), 
serious adverse events, adverse events leading to discontinuation, adverse events with an incidence 
of ≥5% in any treatment group, and non-serious adverse events with an incidence of ≥5% in any 
treatment group.
Clinical Chemistry and Haematology Parameters
Safety laboratory variables will be grouped under “Haematology” and “Clinical Chemistry”.
The baseline is based on the blood sample drawn at stimulation day 1. Treatment-emergent 
laboratory data will be obtained at end-of-stimulation and end-of-trial.
The circulating levels of clinical chemistry and haematology parameters including change from 
baseline will be tabulated for each time-point for each laboratory variable. 
Shift tables will be prepared to compare baseline values to the end-of-stimulation and end-of-trial 
values, using a categorisation of low, normal and high values at each visit. Low, normal and high 
will be defined according to the reference ranges provided by the central laboratory.
For each laboratory variable, a summary table will be prepared displaying the proportion of 
subjects who have at least one markedly abnormal value. The table will also include a break-down 
by classification of the baseline value. Markedly abnormal criteria for the safety laboratory 
variables will be specified in the SAP.
All laboratory values will be listed by subject number and time point. Values outside the reference 
range and markedly abnormal values will be flagged.
Injection Site Reactions
For each injection site reaction (redness, pain, itching, swelling and bruising), the number of events 
and number of subjects experiencing those events will be tabulated by time (immediately, 
30 minutes, 24 hours), reaction and intensity (none, mild, moderate and severe).

subjects with treatment-induced anti-FSH antibodies with neutralising capacity will be tabulated. 
Furthermore, all assessments of anti-FSH antibodies will be listed for subjects with a positive 
results in assay 1). 
Immune-related Adverse Events
Potential immune-related adverse events will be tabulated using the SMQs, PTs and HLTs 
mentioned in section 7.2.22.
Cycle Cancellations due to an Adverse Event, including Immune-related Adverse Events, or 
due to Technical Malfunctions of the Administration Pen
A summary table will be prepared showing the proportion of subjects with cycle cancellations 
including reason for cancellation.
Late OHSS (Including OHSS of Moderate/Severe Grade)
OHSS will for each treatment group be tabulated by classification (mild, moderate, severe) and 
grade (1, 2, 3, 4, 5). Late OHSS is defined as OHSS with onset >9 days after triggering of final 
follicular maturation.
This endpoint will be tabulated and analysed in a similar manner as the proportion of subjects with 
early OHSS. The analysis will be performed for the proportion of subjects with late OHSS and the 
proportion of subjects with late OHSS of moderate or severe grade.
Multi-fetal Gestation, Biochemical Pregnancy, Spontaneous Abortion, Ectopic Pregnancy and 
Vanishing Twins
Frequency tables will be prepared for these endpoints.
Pen Malfunction
The frequency of technical malfunctions of the administration pen will be tabulated.

baseline and end-of-trial assessment for comparison.
Changes in Body Weight 
Body weight will be measured at screening, on stimulation day 1 (baseline) and at end-of-trial. The 
actual measurements and the change from baseline will be tabulated.
Vital Signs
Vital signs and their change from stimulation day 1 (baseline) to end-of-trial will be summarised. 
Shift tables will be prepared to compare the baseline values with the end-of-trial values using the 
categorisation of low, normal and high values. Low, normal and high values will be specified in the 
SAP. All vital signs values will be listed per subject. Values outside the reference range will be 
flagged.
9.9
Post-trial Activities
A separate SAP will be prepared to cover the post-trial information.
The number and percentage of subjects with live birth will be presented by treatment group. 
Subjects with no information on live birth will be defaulted to a negative response.
Neonatal health, including minor/major congenital anomalies, at birth and at 4 weeks after birth 
will be presented by treatment group.
9.10
Interim Analyses and Administrative Review
No interim analysis intended to compare treatment groups with respect to efficacy or safety is 
planned.
A blinded sample size reassessment will take place when data on the primary endpoint are available 
for 70% of the planned subjects or when 800 subjects are randomised, whichever comes first. The 
sample size reassessment will be done without breaking the blind and without inflating the type I 
error of the trial, in line with the current regulatory guidelines for non-inferiority trials by FDA36
and in general by EMA.37
A restricted recalculation rule for the sample size reassessment will be used. Accordingly 1,000 
subjects should be randomised to achieve sufficient power if the ongoing pregnancy rate is 32.2%. 
If the ongoing pregnancy rate is above the expected 32.2%, the sample size can be adjusted up to a 
maximum of 1,144 (572 per treatment group), corresponding to an ongoing pregnancy rate of 50%. 
If the rate is below the expected 32.2% the sample size will not be decreased below the planned 
1,000 subjects.

No specific protocol data can be recorded directly in the e-CRF without prior written or electronic 
record.
If the trial sites use electronic subject record systems, the sponsor will decide if the electronic 
subject records qualify for the trial and document the decision. If the electronic subject records 
system does not qualify for the trial, it may be considered to utilise certified printouts of the data in 
the electronic subject records system for source data as an exception.
The source data for the endocrine parameters, clinical chemistry and haematology parameters will 
be available at the central laboratory. Laboratory reports will be available at the sites.
10.2
e-CRF
An e-CRF system provided by an independent third-party contract research organisation, Target 
Health Inc., will be used for data capture. The system is validated and access at all levels to the 
system is granted / revoked following sponsor and vendor procedures, in accordance with 
regulatory requirements and system requirements.
Data should be entered into the system within a reasonable time after the subject has attended a 
visit or after the data become available, as applicable.
The investigator will approve / authorise the e-CRF entries for each subject, with the exception of 
the treatment allocation module which is un-accessible to the investigator to maintain the assessor-
blinding, with an electronic signature which is equivalent to a handwritten signature.
The e-CRF system and the database will be hosted at Target Health Inc. After the trial database is 
declared clean and locked, a final copy of the database will be stored at Ferring. The investigator 
will also receive a copy of the trial site’s final and locked data (including audit trail, electronic 
signature and queries) as write-protected pdf-files produced by Target Health Inc. The pdf-files will 
be stored in an electronic format and will be provided to the investigator before access to the e-CRF 
is revoked. 
Errors occurring in the e-CRF will be corrected electronically. Such corrections / modifications will 
be automatically tracked by an audit trail detailing the date and time of the correction and the name 
of the person making the correction.

MONITORING PROCEDURES
11.1
Periodic Monitoring
The monitor will contact and visit the investigator periodically to ensure adherence to the protocol, 
International Conference on Harmonisation-Good Clinical Practice (ICH-GCP), standard operating 
procedures and applicable regulatory requirements, maintenance of trial-related source records, 
completeness, accuracy and verifiability of e-CRF entries compared to source data, verification of 
drug accountability and compliance to safety reporting instructions. The investigator will permit the 
monitor direct access to all source data, including electronic medical records, and/or documents in 
order to facilitate data verification. The investigator will co-operate with the monitor to ensure that 
any discrepancies that may be identified are resolved. The investigator is expected to be able to 
meet the monitor during these visits. When the first subject is randomised at the trial site a 
monitoring visit will take place shortly afterwards. For this trial, the frequency of the monitoring 
visits is intended to be approximately every second week (it can be adjusted depending on 
recruitment rate).
11.2
Audit and Inspection
The investigator will make all the trial-related source data and records available at any time to 
quality assurance auditor(s) mandated by Ferring, or to domestic / foreign regulatory inspectors or 
representatives from ethics committees who may audit / inspect the trial.
The main purposes of an audit or inspection are to assess compliance with the trial protocol and the 
principles of ICH-GCP including the Declaration of Helsinki41 and all other relevant regulations.
The subjects must be informed by the investigator and in the Informed Consent Documents that 
authorised Ferring representatives and representatives from regulatory authorities and ethics 
committees may wish to inspect their medical records. During audits / inspections the auditors / 
inspectors may copy relevant parts of the medical records. No personal identification apart from the 
screening / randomisation number will appear on these copies.
The investigator should notify Ferring without any delay of any inspection by a regulatory authority 
or ethics committees.
11.3
Confidentiality of Subject Data
The investigator will ensure that the confidentiality of the subjects’ data will be preserved. In the 
e-CRF or any other documents submitted to Ferring, the subjects will not be identified by their 
names, but by an identification system, which consists of an assigned number in the trial. 
Documents that are not for submission to Ferring, e.g. the confidential subject identification code 
and the signed Informed Consent Documents, will be maintained by the investigator in strict 
confidence.

agreed upon by the investigator and Ferring prior to its implementation. Amendments may be 
submitted for consideration to the approving ethics committees and regulatory authorities, in 
accordance with local regulations. Changes to the protocol to eliminate immediate hazard(s) to trial 
subjects may be implemented prior to ethics committee approval or favourable opinion.
12.2
Deviations from the Protocol
Deviations from the protocol should not occur. If deviations occur, the investigator must inform the 
monitor, and the implications of the deviation must be reviewed and discussed. Any deviation must 
be documented in the e-CRF. A log of protocol deviation reports will be available in the e-CRF. 
Protocol deviation reports and supporting documentation must be kept in the Investigator’s File and 
filed in the Trial Master File at the end of the trial.
12.3

ARCHIVING
16.1
Investigator File
The investigator is responsible for maintaining all the records, which enable the conduct of the trial 
at the site to be fully understood, in compliance with ICH-GCP. The trial documentation including 
all the relevant correspondence should be kept by the investigator for at least 15 years after the 
completion or discontinuation of the trial, if no further instructions are given by Ferring.
The investigator is responsible for the completion and maintenance of the confidential subject 
identification code which provides the sole link between named subject source records and 
anonymous e-CRF data for Ferring. The investigator must arrange for the retention of this Subject 
Identification Log and signed Informed Consent Documents for at least 15 years after the 
completion or discontinuation of the trial.
No trial site document may be destroyed without prior written agreement between the investigator 
and Ferring. Should the investigator elect to assign the trial documents to another party, or move 
them to another location, Ferring must be notified. If the investigator retires and the documents can 
no longer be archived by the site, Ferring can arrange having the Investigator File archived at an 
external archive.
