Abstract

Objective To compare the efficacy and safety of SC depot medroxyprogesterone acetate (DMPA-SC 104) with that of leuprolide acetate in treatment of endometriosis.Design Phase 3, multicenter, randomized, evaluator-blinded, comparator-controlled trial.Setting Clinical trial sites in Canada and United States.Patient(s) Two hundred seventy-four women with surgically diagnosed endometriosis.Intervention(s) Intramuscular injections of DMPA-SC (104 mg) or leuprolide acetate (11.25 mg), given every 3 months for 6 months, with 12 months of posttreatment follow-up.Main outcome measure(s) Reduction in five endometriosis symptoms or signs (dysmenorrhea, dyspareunia, pelvic pain, pelvic tenderness, pelvic induration); change in bone mineral density (BMD), hypoestrogenic symptoms, bleeding, and weight.Result(s) The depot medroxyprogesterone acetate given SC was statistically equivalent to leuprolide in reducing four of five endometriosis symptoms or signs at the end of treatment (month 6) and in reducing all five symptoms after 12 months' follow-up (month 18). Patients in the DMPA-SC 104 group showed significantly less BMD loss than did leuprolide patients at month 6, with scores returning to baseline at 12 months' follow-up. No statistically significant differences in median weight changes were observed between groups. Compared with leuprolide, DMPA-SC 104 was associated with fewer hypoestrogenic symptoms but more irregular bleeding.Conclusion(s) Efficacy of DMPA-SC 104 was equivalent to that of leuprolide for reducing endometriosis-associated pain, with less impact on BMD and fewer hypoestrogenic side effects but more bleeding.

  • Depot medroxyprogesterone acetate has demonstrated efficacy equivalent to leuprolide acetate, but long-term use impacts adversely on bone mineral density, and the delay in resumption of ovulation that may follow discontinuation is a contraindication in women wishing to conceive in the near future.

    “Depot medroxyprogesterone acetate (MPA; 104 mg, subcutaneous injection, every 3 months) has demonstrated an efficacy equivalent to LA, but long-term use of depot MPA preparations is shown to impact adversely on bone mineral density (BMD), while the delay in resumption of ovulation that may follow discontinuation of this therapy is a contraindication to use in women wishing to conceive in the near”

  • MPA is as effective as GnRH agonists in reducing endometriosis-related pain.

    “MPA appeared to be more effective than placebo [214] and as effective as danazol [215] and GnRH-agonists [216, 217] in reducing endometriosis-related pain.”
  • Irregular uterine bleeding is a known adverse effect of treatment with progestins, including depot preparations of MPA, which have been compared in trials against LA.

    “Irregular uterine bleeding is a known adverse effect of treatment with progestins, including depot preparations of MPA, which have been compared in trials against LA (Vercellini et al., 2003;Crosignani et al., 2006;Schlaff et al., 2006).”
  • In two large multicenter evaluator-blinded comparator-controlled trials, subcutaneous DMPA 104 mg/0.65 ml was statistically equivalent to leuprolide acetate in reducing pain symptoms after 12 months' follow-up.

    “In both studies DMPA-SC was statistically equivalent to GnRHa in reducing pain symptoms after 12 months' follow-up.”
  • In those trials, DMPA-SC group showed significantly less BMD loss than leuprolide at month 6, and BMD returned to pretreatment levels at 12 months in DMPA-SC group but not leuprolide group.

    “Patients in the DMPA-SC group showed significantly less BMD loss than did leuprolide patients at month 6.”

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.

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.
