SAINT-PREX, Switzerland--(BUSINESS WIRE)--Ferring Pharmaceuticals announced today a new analysis of Rekovelle (follitropin delta) data that showed cumulative live birth rates were similar between women receiving Rekovelle and conventional follitropin alfa treatment.1 In addition, Rekovelle data from a separate new analysis showed a favourable safety profile in women with high anti-Mllerian hormone (AMH) levels.2 These analyses of the ESTHER-1 and ESTHER-2 Phase III clinical trials3,4 were presented today at the 33rd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) in Geneva, Switzerland.

Rekovelles individualised dosing regimen, based on a patients AMH level and body weight, provides clinicians with a consistent, evidence-based approach to personalising treatment for their patients, said Per Falk, Executive Vice President and Chief Scientific Officer, Ferring Pharmaceuticals. These new Rekovelle analyses add further evidence for a personalised approach to fertility treatment for patients.

A new analysis of the ESTHER-1 and ESTHER-2 trials showed that in women undergoing in vitro fertilisation (IVF), the cumulative live birth rate for fresh embryo transfers after three treatment cycles was 43.9% (292/665) with Rekovelle and 44.5% (294/661) with follitropin alfa.1 In addition, ongoing pregnancy rate was 45.1% (300/665) and 45.7% (302/661), respectively.1 The ESTHER trials3,4 were not powered for this analysis, so no confirmatory conclusions can be derived.

A separate new analysis of the ESTHER-1 trial was conducted to evaluate ongoing pregnancy rates, early ovarian hyperstimulation syndrome (OHSS) and preventive interventions for early OHSS in women with different AMH levels.2 For women with high AMH 35 pmol/L (13% of the trial population) the incidence of early OHSS with Rekovelle was lower (4.7%, 4/86) compared with conventional follitropin alfa dosing (11.9%, 10/84). The number of patients requiring preventive interventions for early OHSS was also lower (4.7%, 4/86 and 23.8%, 20/84 respectively). In addition, patients maintained ongoing pregnancy rate.2 The ESTHER trials3,4 were not powered for this analysis, so no confirmatory conclusions can be derived.

About Rekovelle(follitropin delta) Rekovelle is the first recombinant follicle stimulating hormone (rFSH) derived from a human cell line (PER.C6 cell line).3,5,6,7 It has been developed for individualised dosing based on a patients body weight and serum AMH level, as determined by a companion diagnostic, the Elecsys AMH Plus immunoassay from Roche.3,8,9 Rekovelle is structurally and biochemically distinct from other existing recombinant FSH treatments.3,5,6,7

Rekovelle received Marketing Authorisation from the European Commission (EC) in December 2016.

About the ESTHER trials ESTHER-1 (Evidence-based Stimulation Trial with Human recombinant FSH in Europe and Rest of World) is a Phase 3, randomised, assessor-blind, controlled trial of 1326 patients in 11 countries undergoing their first ART cycle. Patients were randomized 1:1 to receive treatment with individualised Rekovelle, a fixed daily dose based on serum anti-Mllerian hormone (AMH) levels and body weight, or conventional follitropin alfa dosing. The co-primary endpoints of ongoing pregnancy rates and ongoing implantation rates were met and results showed no difference between the two treatment arms. Results of the ESTHER-1 trial were published in the February 2017 issue of Fertility & Sterility.3

ESTHER-2 is a Phase 3, assessor-blind, controlled trial evaluating the immunogenicity of Rekovelle in a subset of ESTHER-1 patients undergoing repeated cycles of controlled ovarian stimulation for ART. Data demonstrated no increased immunogenicity risk with Rekovelle after exposure in repeated cycles.4

About AMH and OHSS AMH is a biomarker used to assess ovarian reserve and can help predict ovarian response.10 Women with high AMH levels are at an increased risk of developing OHSS, a potential complication of IVF treatment.11,12 Symptoms of early OHSS may include abdominal distension or discomfort, nausea and vomiting. In more severe cases OHSS can lead to large amounts of ascites (fluid accumulation in the abdominal cavity), shortness of breath, blood clots, dehydration and potentially, death.11

The prevalence of OHSS in women undergoing IVF varies according to severity, with cases of OHSS experienced by 2033% (mild), 36% (moderate) and 0.12% (severe) of women.13 A recent report suggested that OHSS is an underreported side effect of ovarian stimulation and the real world incidence may be higher.14 In addition to the impact on patients, the treatment of OHSS is associated with significant costs to the healthcare system.15 In the UK for example, the cost of treating moderate and severe cases of OHSS is estimated to be over 7 million every year.15,16

About the ElecsysAMH Plus immunoassay from Roche The Elecsys AMH Plus immunoassay from Roche has been shown to provide a precise, reliable and robust measurement of AMH levels.8,9,17,18,19,20 This fully automated Elecsys AMH Plus immunoassay, run on the cobase and Elecsys immunoassay analysers, determines AMH levels in 18 minutes, making it appropriate for routine clinical use. The Elecsys AMH Plus immunoassay is intended to be used for assessment of ovarian reserve, prediction of response to COS and establishment of the individual daily dose of Rekovelle in combination with body weight in COS for the development of multiple follicles in women undergoing an assisted reproductive technology programme.8,9,17,18,19,20
