简要总结
This clinical study examines whether tirzepatide can improve ovarian dysfunction in premenopausal women with polycystic ovary syndrome (PCOS) who are overweight or have obesity. Tirzepatide is already approved for the treatment of diabetes and obesity, but its effects on ovarian dysfunction in PCOS are not yet known. Participants will be randomly assigned to tirzepatide or placebo in a double-blinded manner.
The goal of the study is to demonstrate that tirzepatide, at the maximum tolerated dose, is superior to placebo for improvement of ovarian dysfunction as defined by menstrual irregularity in overweight or obesity-related PCOS.
All participants will have a screening visit, followed by 72 weeks of treatment. Treatment includes a 20-week dose-escalation period and a 52-week maintenance period. Lower doses may be used if side effects occur, and the highest tolerated dose will be continued through the maintenance phase. A 4-week safety follow-up will take place after treatment, and long-term follow-up will continue for one year. The study will take place at five clinical trial sites in Germany.
详细描述
PERIODS is a prospective, phase IV, multi-centre, randomized, double-blind and placebo-controlled clinical trial that will investigate the effects of tirzepatide compared with placebo on ovarian dysfunction in premeno-pausal, overweight (BMI ≥ 27 kg/m2) women with PCOS. The primary endpoint is the improvement of ovarian dysfunction as defined by menstrual irregularity and ovulation frequency in overweight or obesity-related PCOS.
All subjects will undergo a screening visit and a 72-week treatment period including a 20-week dose escalation up to the maximum tolerated dose. Lower doses of tirzepatide are permitted if intolerable side effects occur. However, even if a lower dose of tirzepatide turns out to be the maximum tolerated dose, this lower dose will be administered for the entire 20-week dose escalation period, followed by the 52-week maintenance dose.
The safety follow-up period will be 4 weeks (for subjects completing or discontinuing IMP during the first 72 weeks). Long-term follow-up will be one year after discontinuation of IMP.
The trial design is multi-centred with a planned number of 5 participating trial sites in Germany.
