Relugolix for oral treatment of uterine leiomyomas: a dose-finding, randomized, controlled trial
Ontology highlight
ABSTRACT: Background
Uterine leiomyomas are the most common neoplasm affecting women and frequently cause heavy menstrual bleeding and pain. Gonadotropin-releasing hormone (GnRH) receptor antagonists provide fast symptom relief and show promise as a medical (non-surgical) treatment option and as a presurgical treatment to reduce leiomyoma size. The aim of this study was to evaluate the efficacy and safety of three dose levels of oral relugolix, a small molecule GnRH receptor antagonist, in Japanese women with uterine leiomyomas and heavy menstrual bleeding.

Project description:ObjectiveTo assess efficacy and tolerability of ulipristal acetate, a selective progesterone receptor modulator, for treatment of symptomatic uterine leiomyomas.MethodsThis phase 3, double-blind, placebo-controlled study enrolled premenopausal women (aged 18-50 years) with abnormal uterine bleeding, one or more discrete leiomyomas, and uterine size 20 weeks of gestation or less. Patients were randomized 1:1:1 to 5 mg ulipristal, 10 mg ulipristal, or placebo once daily for 12 weeks followed by 12-week drug-free follow-up. Coprimary endpoints were rate of and time to amenorrhea, defined as no bleeding for the last 35 consecutive days of treatment. Secondary endpoints included rates of amenorrhea from day 11 and change from baseline to endpoint in the Revised Activities subscale of the Uterine Fibroid Symptom and Quality of Life questionnaire, which includes questions pertaining to physical and social activities. Safety assessments included adverse event monitoring and endometrial biopsies. A sample size of 150 was planned to compare separately each dose of ulipristal with placebo.ResultsFrom March 2014 to March 2016, 157 patients were randomized. Demographics were similar across treatment groups. Amenorrhea was achieved by 25 of 53 (47.2% [97.5% CI 31.6-63.2]) and 28 of 48 (58.3% [97.5% CI 41.2-74.1]) patients treated with 5 mg and 10 mg ulipristal, respectively, compared with 1 of 56 (1.8% [97.5% CI 0.0-10.9]) placebo-treated patients (both P<.001). Time to amenorrhea was shorter for both ulipristal doses compared with placebo (P<.001), and both doses of ulipristal resulted in improved quality of life compared with placebo (P<.001). Common adverse events (5% or greater in either ulipristal group during treatment) were hypertension, elevated blood creatinine phosphokinase, and hot flushes. Serious adverse events occurred in four patients, but none was considered related to treatment. Endometrial biopsies were benign.ConclusionUlipristal at 5 mg and 10 mg were well tolerated and superior to placebo in rate of and time to amenorrhea in women with symptomatic uterine leiomyomas.Clinical trial registrationClinicaltrials.gov number, NCT02147197.

Project description:ObjectiveIn the LIBERTY 1 and LIBERTY 2 placebo-controlled trials, once-daily relugolix combination therapy reduced menstrual blood loss volume and pain in women with heavy menstrual bleeding associated with uterine leiomyomas and was well tolerated, with preservation of bone mineral density (BMD) through 24 weeks. Here we report the long-term efficacy and safety of relugolix combination therapy treatment for up to 52 weeks.MethodsWomen with uterine leiomyoma-associated heavy menstrual bleeding who completed any treatment arm in either the LIBERTY 1 or LIBERTY 2 trial were eligible to enroll in a 28-week long-term extension study. All participants received once-daily relugolix combination therapy (40 mg relugolix, estradiol 1 mg, norethindrone acetate 0.5 mg) in the extension study. The primary efficacy endpoint was the proportion of women who achieved or maintained a menstrual blood loss volume of less than 80 mL and a 50% or greater reduction in menstrual blood loss volume from LIBERTY study baseline to the last 35 days of treatment (defined as responders ). Analyses were conducted for all three randomized treatment groups from pivotal studies.ResultsOverall, 477 women enrolled, 476 were treated, and 363 (76.1%) completed 52 weeks. Among patients treated with relugolix combination therapy through 52 weeks (n=163), sustained improvement in heavy menstrual bleeding was observed in 87.7% (responders). The least squares mean menstrual blood loss volume reduction was 89.9%, with 70.6% of patients achieving amenorrhea. At week 52, 59.0% of patients with anemia at baseline had improvements in hemoglobin concentration of greater than 2 g/dL. Distress due to uterine leiomyoma-associated symptoms measured by the BPD (Bleeding and Pelvic Discomfort) scale score was reduced by 51.3 points. Sustained reductions in uterine and uterine leiomyoma volume were observed. Bone mineral density was preserved through week 52.ConclusionImprovements in heavy menstrual bleeding and anemia and reduction of uterine leiomyoma-associated symptom burden were sustained through up to 52 weeks of treatment with relugolix combination therapy in women with uterine leiomyomas. No new safety concerns were identified, and BMD was maintained.Clinical trial registrationClinicalTrials.gov , NCT03049735; NCT03103087; NCT03412890.Funding sourceMyovant Sciences GmbH.

Project description:ObjectiveTo investigate effects of ulipristal acetate on health-related quality of life (QOL) and symptom severity in women with symptomatic uterine leiomyomas and abnormal uterine bleeding.MethodsWomen were randomized to ulipristal (5 mg, 10 mg) or placebo in two phase 3, multicenter, double-blind, placebo-controlled trials (VENUS I and II). Health-related QOL and symptom severity were assessed at baseline, and over one (VENUS I and II) and two (VENUS II) 12-week treatment courses using the Uterine Fibroid Symptom Health-Related Quality of Life questionnaire. In pooled VENUS I and II data, change from baseline to the end of the first course for each Uterine Fibroid Symptom Health-Related Quality of Life scale was analyzed, including a Revised Activities subscale that measured physical and social activities. The proportion of women achieving meaningful change in the Symptom Severity (20 or more points), Health-Related QOL Total (20 or more points), and Revised Activities (30 or more points) scales was calculated. In VENUS II data, change from baseline to the end of each course in each scale was analyzed for each treatment arm.ResultsIn pooled analyses, the intent-to-treat population included 589 patients (placebo, n=169; ulipristal 5 mg, n=215; ulipristal 10 mg, n=205). Significantly greater improvements from baseline in all Uterine Fibroid Symptom Health-Related Quality of Life scales were observed with both ulipristal doses compared with placebo (P<.001). A meaningful change in Revised Activities was achieved by 51 patients receiving placebo (34.9%), compared with 144 (73.5%; OR 5.0 [97.5% CI 2.9-8.6]) and 141 (80.6%; OR 7.9 [97.5% CI 4.3-14.6]) patients receiving ulipristal 5 mg, and 10 mg, respectively. In VENUS II, at end of courses 1 and 2, both ulipristal doses demonstrated significant improvements from baseline compared with placebo for all Uterine Fibroid Symptom Health-Related Quality of Life scales (P<.01). Mean Revised Activities scores showed that beneficial ulipristal effects were maintained in course 2, and improvements occurred on switching to ulipristal; results for other scales were similar.ConclusionUlipristal was associated with significant improvements in health-related QOL and symptom severity compared with placebo for women with symptomatic uterine leiomyomas.Clinical trial registrationClinicalTrials.gov, NCT02147197 and NCT02147158.Funding sourceAllergan plc, Dublin, Ireland.

Project description:A novel subcutaneous allergen immunotherapy formulation (gpASIT+™) containing Lolium perenne peptides (LPP) and having a short up-dosing phase has been developed to treat grass pollen-induced seasonal allergic rhinoconjunctivitis. We investigated peptide immunotherapy containing the hydrolysate from perennial ryegrass allergens for the optimum dose in terms of clinical efficacy, immunogenicity and safety.This prospective, double-blind, placebo-controlled, phase IIb, parallel, four-arm, dose-finding study randomized 198 grass pollen-allergic adults to receive placebo or cumulative doses of 70, 170 or 370 ?g LPP. All patients received weekly subcutaneous injections, with the active treatment groups reaching assigned doses within 2, 3 and 4 weeks, respectively. Efficacy was assessed by comparing conjunctival provocation test (CPT) reactions at baseline, after 4 weeks and after completion. Grass pollen-specific immunoglobulins were analysed before and after treatment.Conjunctival provocation test (CPT) response thresholds improved from baseline to V7 by at least one concentration step in 51.2% (170 ?g; P = .023), 46.3% (370 ?g), and 38.6% (70 ?g) of patients receiving LPP vs 25.6% of patients receiving placebo (modified per-protocol set). Also, 39% of patients in the 170-?g group became nonreactive to CPT vs 18% in the placebo group. Facilitated allergen-binding assays revealed a highly significant (P < .001) dose-dependent reduction in IgE allergen binding across all treatment groups (70 ?g: 17.1%; 170 ?g: 18.8%; 370 ?g: 26.4%). Specific IgG4 levels increased to 1.6-fold (70 ?g), 3.1-fold (170 ?g) and 3.9-fold (370 ?g) (mPP).Three-week immunotherapy with 170 ?g LPP reduced CPT reactivity significantly and increased protective specific antibodies.

Project description:BackgroundUterine fibroids are a common cause of heavy menstrual bleeding and pain. Treatment with the combination of relugolix (an oral gonadotropin-releasing hormone-receptor antagonist), estradiol, and norethindrone acetate, administered once daily, may have efficacy in women with uterine fibroids and heavy bleeding while avoiding hypoestrogenic effects.MethodsWe conducted two replicate international, double-blind, 24-week, phase 3 trials involving women with fibroid-associated heavy menstrual bleeding. Participants were randomly assigned in a 1:1:1 ratio to receive once-daily placebo, relugolix combination therapy (40 mg of relugolix, 1 mg of estradiol, and 0.5 mg of norethindrone acetate), or delayed relugolix combination therapy (40 mg of relugolix monotherapy, followed by relugolix combination therapy, each for 12 weeks). The primary efficacy end point in each trial was the percentage of participants with a response (volume of menstrual blood loss <80 ml and a ≥50% reduction in volume from baseline) in the relugolix combination therapy group, as compared with the placebo group. Key secondary end points were amenorrhea, volume of menstrual blood loss, distress from bleeding and pelvic discomfort, anemia, pain, fibroid volume, and uterine volume. Safety and bone mineral density were assessed.ResultsA total of 388 women in trial L1 and 382 in trial L2 underwent randomization. A total of 73% of the participants in the relugolix combination therapy group in trial L1 and 71% of those in trial L2 had a response (primary end point), as compared with 19% and 15%, respectively, of those in the placebo groups (P<0.001 for both comparisons). Both relugolix combination therapy groups had significant improvements, as compared with the placebo groups, in six of seven key secondary end points, including measures of menstrual blood loss (including amenorrhea), pain, distress from bleeding and pelvic discomfort, anemia, and uterine volume, but not fibroid volume. The incidence of adverse events was similar with relugolix combination therapy and placebo. Bone mineral density was similar with relugolix combination therapy and placebo but decreased with relugolix monotherapy.ConclusionsOnce-daily relugolix combination therapy resulted in a significant reduction in menstrual bleeding, as compared with placebo, and preserved bone mineral density in women with uterine fibroids.

Project description:OBJECTIVE:To evaluate whether 3-month administration of CDB-2914, a selective progesterone receptor modulator, reduces leiomyoma size and symptoms. METHODS:Premenopausal women with symptomatic uterine leiomyomata were randomly assigned to CDB-2914 at 10 mg (T1) or 20 mg (T2) daily or to placebo (PLC) for 3 cycles or 90-102 days if no menses occurred. The primary outcome was leiomyoma volume change determined by magnetic resonance imaging at study entry and within 2 weeks of hysterectomy. Secondary outcomes included the proportion of amenorrhea, change in hemoglobin and hematocrit, ovulation inhibition, and quality-of-life assessment. RESULTS:Twenty-two patients were allocated, and 18 completed the trial. Age and body mass index were similar among groups. Leiomyoma volume was significantly reduced with CDB-2914 administration (PLC 6%; CDB-2914 -29%; P=.01), decreasing 36% and 21% in the T1 and T2 groups, respectively. During treatment, hemoglobin was unchanged, and the median estradiol was greater than 50 pg/mL in all groups. CDB-2914 eliminated menstrual bleeding and inhibited ovulation (% ovulatory cycles: CDB-2914, 20%; PLC, 83%; P=.001). CDB-2914 improved the concern scores of the uterine leiomyoma symptom quality-of-life subscale (P=.04). One CDB-2914 woman developed endometrial cystic hyperplasia without evidence of atypia. No serious adverse events were reported. CONCLUSION:Compared with PLC, CDB-2914 significantly reduced leiomyoma volume after three cycles, or 90-102 days. CDB-2914 treatment resulted in improvements in the concern subscale of the Uterine Fibroid Symptom Quality of Life assessment. In this small study, CDB-2914 was well-tolerated without serious adverse events. Thus, there may be a role for CDB-2914 in the treatment of leiomyomata.

Project description:ObjectiveTo evaluate elagolix, an oral gonadotropin-releasing hormone receptor antagonist, alone or with add-back therapy, in premenopausal women with heavy menstrual bleeding (greater than 80 mL per month) associated with uterine leiomyomas.MethodsThis double-blind, randomized, placebo-controlled, parallel-group study evaluated efficacy and safety of elagolix in cohorts 1 (300 mg twice daily) and 2 (600 mg daily) with four arms per cohort: placebo, elagolix alone, elagolix with 0.5 mg estradiol/0.1 norethindrone acetate, and elagolix with 1.0 mg estradiol/0.5 mg norethindrone acetate. A sample size of 65 per group was planned to compare elagolix with add-back to placebo on the primary end point: the percentage of women who had less than 80 mL menstrual blood loss and 50% or greater reduction in menstrual blood loss from baseline to the last 28 days of treatment. Safety assessments included changes in bone mineral density.ResultsFrom April 8, 2013, to December 8, 2015, 571 women were enrolled, 567 were randomized and treated (cohort 1=259; cohort 2=308), and 80% and 75% completed treatment, respectively. Participants had a mean±SD age of 43±5 years (cohort 2, 42±5 years), and 70% were black (cohort 2, 74%). Primary end point responder rates in cohort 1 (cohort 2) were 92% (90%) for elagolix alone, 85% (73%) for elagolix with 0.5 mg estradiol/0.1 mg norethindrone acetate, 79% (82%) for elagolix with 1.0 mg estradiol/0.5 mg norethindrone acetate, and 27% (32%) for placebo (all P<.001 vs placebo). Elagolix groups had significant decreases compared with placebo in lumbar spine bone mineral density, which was attenuated by adding 1.0 mg estradiol/0.5 mg norethindrone acetate.ConclusionElagolix with and without add-back significantly reduced menstrual blood loss in women with uterine leiomyomas. Add-back therapy reduced hypoestrogenic effects on bone mineral density.Clinical trial registrationClinicalTrials.gov, NCT01817530; EU Clinical Trial Register, 2013-000082-37.

Project description:Tetrodotoxin (TTX) has emerged as a potentially efficacious agent for chemotherapy-induced neuropathic pain (CINP), a prevalent, debilitating condition often resistant to analgesics. This randomized, double-blind, dose-finding study was undertaken to explore safety and trends in efficacy of four TTX doses and to identify a dose for further study. One hundred and twenty-five patients with taxane- or platinum-related CINP received subcutaneous placebo or TTX (7.5 µg twice daily (BID), 15 µg BID, 30 µg once daily (QD), 30 µg BID) for four consecutive days. Primary outcome measure was average patient-reported Numeric Pain Rating Scale (NPRS) score during Days 21-28 post-treatment. Changes in mean NPRS score were not statistically different between cohorts, due to small trial size and influence of a few robust placebo responders. Cumulative responder analysis showed significant difference from placebo with 30 µg BID cohort using the maximum response at any timepoint (p = 0.072), 5-day (p = 0.059), 10-day (p = 0.027), and 20-day (p = 0.071) rolling averages. In secondary quality of life (QOL) outcomes, 30 µg BID cohort also differed significantly from placebo in a number of SF-36 and CIPN20 subscales. Most adverse events (AE) were mild or moderate with oral paresthesia (29.6%) and oral hypoesthesia (24.8%) as most common.
