Study Question: Are progesterone vaginal pessaries 400 mg twice a day (bid) non-inferior to progesterone vaginal gel (90 mg) once a day (od) in the primary endpoint of clinical pregnancy rate after 38 days of luteal phase support in women undergoing in vitro fertilisation (IVF)?, Summary Answer: Non-inferiority of progesterone vaginal pessaries 400 mg bid to progesterone 8% vaginal gel (90 mg od) was shown for clinical pregnancy rate after 38 days of luteal phase support., What Is Known Already: To maximise successful embryo transfer after IVF, additionally administered progesterone is used for proper endometrium transformation in the luteal phase. Vaginally administered progesterone results in adequate secretory transformation of the endometrium., Study Design, Size, Duration: This multicentre, multinational, open, randomised, two-parallel group, non-inferiority Phase 3 clinical trial was carried out at 17 study sites in five European countries (Belgium, Bulgaria, Czech Republic, Hungary and Serbia) between October 2013 and August 2014. An interactive web response system (IWRS) was implemented for treatment allocation at the sites. Power analysis, based on the assumptions of a non-inferiority margin of -9%, a significance level of α 2.5% (one-sided), power 90%, at a reference pregnancy rate for the progesterone vaginal gel group of 30%, as well as applying a dropout rate of 10%, yielded a total number of 766 patients to be randomised., Participants/materials, Setting, Methods: Women aged between 18 and 40 years with a clinical indication for IVF/intracytoplasmic sperm injection (ICSI) and embryo transfer were eligible to participate. The clinical pregnancy rate was assessed by fetal heart movement measured by transvaginal ultrasound at day 38 (D38) (primary endpoint) and D70. Also assessed were biochemical pregnancy rate (assessed by serum β-hCG ≥25 IU/L), clinical implantation rates at D38, patient evaluation of vaginal bleeding and discharge (assessed by diary) and adverse event (AE) incidence, severity and relationship to study medication., Main Results and the Role of Chance: A total of 769 female patients were randomised to progesterone 400 mg vaginal pessaries bid (n = 385, 50.1%) or progesterone 90 mg vaginal gel od (n = 384, 49.9%). Patients receiving progesterone vaginal pessaries and progesterone vaginal gel were comparable in demographics, baseline characteristics and number of retrieved oocytes. In the full analysis set (FAS; n = 369 progesterone vaginal pessaries and n = 368 progesterone vaginal gel), clinical pregnancy rates on D38 were 38.3% for progesterone vaginal pessaries and 39.9% for progesterone vaginal gel. In the per protocol analysis set (PP; n = 357 progesterone vaginal pessaries and n = 356 progesterone vaginal gel), clinical pregnancy rates on D38 were 38.1% for progesterone vaginal pessaries and 40.4% for progesterone vaginal gel. For the differences in pregnancy rates between the progesterone vaginal pessaries group and the progesterone vaginal gel, the lower limit of the 97.5% CI was -8.6 and -9.5% for the FAS and PP datasets, respectively. The original prespecified non-inferiority margin of -9% was thus met in the FAS dataset but was marginally below this in the PP dataset. However, the pregnancy rate of the comparator was higher than the anticipated rate of 30%, and a predetermined logistic regression model including treatment group, country and age group effects without interaction terms showed non-inferiority of progesterone vaginal pessaries to progesterone vaginal gel for both the FAS and PP populations, in that the lower limits of the 95% CIs were above 0.7 for both analyses. As a result of this, the relevant authorities accepted to widen the acceptable non-inferiority margin to -10%, and as such both the FAS and PP populations succeeded in showing non-inferiority. Biochemical pregnancy and clinical implantation rates were comparable for both treatments. Both treatment groups showed similar high compliance throughout the study, and the safety profiles were also comparable between the groups. Drug-related AEs occurred with frequencies of 15.1% with progesterone vaginal pessaries and 14.4% with progesterone vaginal gel., Limitations, Reasons for Caution: Clinical pregnancy rate is a surrogate for the outcome of live birth rate., Wider Implications of the Findings: Progesterone 400 mg pessaries bid for luteal phase support is an effective, safe and tolerable treatment option for women undergoing IVF during ART., Study Funding/competing Interest(s): This work was funded by Actavis Group PTC ehf., Iceland, part of Teva Pharmaceuticals, and by L.D. Collins & Co. Ltd. Gedeon Richter plc has recently entered into a license and distribution agreement to commercialise the vaginal pessaries in the European Union (except Ireland/UK). The progesterone vaginal pessaries studied are now marketed as Cyclogest®, Amelgen®, Cyclovita®, Luteum and Cygest® throughout the EU, Asia and Middle East & North Africa.

Introduction: Endometriosis is one of the most common gynaecological diseases affecting 70 million women worldwide., Aim: The aims of this study were to determinate the diagnostic delay of endometriosis, to assess the effectiveness of surgical and combined therapy and to analyse the quality of life of women suffering from this disease., Method: Of the 240 patients with endometriosis enrolled in the study, 84 patients filled in a prospective as well as a retrospective questionnaire., Results: There was a 3.9 year delay from the onset of symptoms to the definitive diagnosis. Before therapy, 89% of the patients reported endometriosis related pain, while after therapy only 28% in the prospectively investigated months (p = 0.025). There was no significant difference between the outcome of surgical treatment alone and combined operative and medical therapy (p = 0.85). Reduced productivity at work was present in 47% of the patients and 40% of the patients reported impaired personal relationship, too. Endometriosis-associated symptoms generated 0.147 quality-adjusted life years per woman., Conclusions: This study is the first ever prospective survey to investigate the impact of endometriosis on the quality of life in Hungary. The results indicated a long diagnostic delay. Both surgical and combined therapies proved to be efficient. Endometriosis impaired health-related quality of life, but adequate therapy attenuated the severity of symptoms.
