Dienogest is as effective as leuprolide acetate in treating the painful symptoms of endometriosis: a 24-week, randomized, multicentre, open-label trial
Abstract
BACKGROUND: Dienogest is a selective progestin that has been investigated in a clinical trial programme for the treatment of endometriosis. The current non-inferiority trial compared the efficacy and safety of dienogest against leuprolide acetate (LA) for treating the pain associated with endometriosis. METHODS: Patients with confirmed endometriosis were randomized to treatment with dienogest (2 mg/day, orally) or LA (3.75 mg, depot i.m. injection, every 4 weeks) for 24 weeks. The primary efficacy variable was absolute change in pelvic pain from baseline to end of treatment, assessed by visual analogue scale (VAS). Safety variables included adverse event profile, laboratory parameters, bone mineral density (BMD), bone markers and bleeding patterns. RESULTS: A total of 252 women were randomized to treatment with dienogest (n = 124) or LA (n = 128); 87.9 and 93.8% of the respective groups completed the trial. Absolute reductions in VAS score from baseline to Week 24 were 47.5 mm with dienogest and 46.0 mm with LA, demonstrating the equivalence of dienogest relative to LA. Hypoestrogenic effects (e.g. hot flushes) were reported less frequently in the dienogest group. As expected, bleeding episodes were suppressed less with dienogest than with LA. Changes in mean lumbar BMD between screening and final visit were +0.25% with dienogest and -4.04% with LA subgroups (P = 0.0003). Markers of bone resorption increased with LA but not dienogest. CONCLUSIONS: Dienogest 2 mg/day orally demonstrated equivalent efficacy to depot LA at standard dose in relieving the pain associated with endometriosis, although offering advantages in safety and tolerability.

“As is appropriate for noninferiority studies (Piaggio et al., 2006), the primary analysis was based on the per protocol set (PPS), which included all randomized patients except those with major protocol deviations that affected the primary efficacy variable.”

The Methodological Issues section (p. 2) says per-protocol or other non-ITT analyses might be desirable in noninferiority trials because ITT can increase the risk of falsely concluding noninferiority. It also warns that excluding nonadherent patients can bias results in either direction, so it does not unconditionally endorse a per-protocol primary analysis. The cited paper does not define the citing study’s specific PPS exclusions; those are the citing authors’ description of their own analysis. (LLM, conf=0.84)

The Introduction and Conclusions say progestogens can be used long term and effectively control endometriosis pain. The Results report weight gain with some treatments and describe medroxyprogesterone acetate as having moderate androgenic activity. They do not establish that high doses are required for efficacy or link those adverse effects specifically to such doses. (LLM, conf=0.86)

The intramuscular-route section identifies DMPA as a depot formulation of MPA and says uterine breakthrough bleeding may be prolonged and repeated.

The Safety and Tolerability section reports more intermenstrual bleeding and significantly more bleeding or spotting days with depot medroxyprogesterone acetate (DMPA-SC 104) than with leuprolide. The discussion (p. 323) identifies increased spotting and bleeding as the treatment’s most significant disadvantage and describes its side effects as typical of progestin-only contraception.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
