Article Synopsis
  • Two clinical trials, LIBERTY 1 and LIBERTY 2, studied the effectiveness of relugolix combination therapy versus placebo in reducing heavy menstrual bleeding and pain in women with uterine fibroids over a 24-week period.
  • Results showed that a significantly higher percentage of women on relugolix reported minimal or no menstrual (65% vs. 19%) and non-menstrual (45% vs. 22%) pain compared to those on placebo.
  • The researchers concluded that relugolix combination therapy was effective in reducing pain from uterine fibroids, with many women experiencing a one-third reduction in their worst pain symptoms.

Objective: To investigate the effects of 52 weeks of treatment with relugolix combination therapy (relugolix 40 mg, estradiol 1 mg, norethindrone acetate 0.5 mg) on symptoms of uterine fibroids (UF) and quality of life (QoL) in women with heavy menstrual bleeding associated with UF and anemia (hemoglobin ≤10.5 g/dL) at baseline.

A 16-year-old warmblood mare was referred with a progressive history of behavioral changes and left-sided blindness. Following neuroanatomical localization to the forebrain, magnetic resonance imaging of the head revealed a well-delineated, 4.5 cm in diameter, round pituitary mass causing marked compression of the midbrain and optic chiasm.

Background: In the LIBERTY Long-Term Extension study, once-daily relugolix combination therapy (40 mg relugolix, estradiol 1 mg, norethindrone acetate 0.5 mg) substantially improved uterine fibroid-associated heavy menstrual bleeding throughout the 52-week treatment period in the overall study population.

Objective: Black or African American women typically experience a greater extent of disease and symptom burden of uterine fibroids vs other racial groups and have traditionally been underrepresented in clinical trials.

Background: In the pivotal LIBERTY 1 and 2 trials and long-term extension study, once-daily relugolix combination therapy (40 mg relugolix, 1 mg estradiol, 0.5 mg norethindrone acetate) reduced menstrual blood loss volume and pain among women with uterine fibroids. Relugolix combination therapy was well tolerated with preservation of bone mineral density through 52 weeks.

What is this summary about? This is a summary of a research study (known as a clinical trial) called the LIBERTY extension study. The LIBERTY extension study is a long-term study looking at how well a medicine called relugolix combination therapy worked in reducing blood loss during menstrual periods in women with uterine fibroids with heavy menstrual periods. Women were included in the extension study if they finished the 24-week LIBERTY 1 or LIBERTY 2 studies.

Background And Objective: Relugolix is a gonadotropin-releasing hormone receptor antagonist. Relugolix 40-mg monotherapy is associated with vasomotor symptoms and long-term bone mineral density loss due to hypoestrogenism. This study assessed whether the addition of estradiol (E2) 1 mg and norethindrone acetate (NETA) 0.

Article Synopsis
  • The LIBERTY 1 and LIBERTY 2 studies evaluated the effectiveness of relugolix combination therapy in reducing heavy menstrual bleeding in women with uterine fibroids compared to a placebo.
  • Approximately 73% of women in LIBERTY 1 and 71% in LIBERTY 2 experienced significant reductions in menstrual blood loss after 24 weeks of treatment.
  • Common side effects included headaches and hot flushes, but overall, the side effects were comparable among the treatment and placebo groups.

Background: Symptomatic uterine fibroids are burdensome to live with; they are associated with symptom-related distress, affect daily activities, and reduce health-related quality of life. The LIBERTY randomized clinical trials showed that oral relugolix combination therapy (40 mg relugolix, 1 mg estradiol, and 0.5 mg norethindrone acetate once daily) markedly improved fibroid-associated symptoms and conditions, including heavy menstrual bleeding, pain, and anemia, and was well-tolerated.

Objective: In 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.

Methods: Women 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.

Objective: To assess the effect of once-daily relugolix combination therapy (relugolix-CT: relugolix 40 mg, estradiol 1 mg, and norethindrone acetate 0.5 mg) compared with placebo on moderate-to-severe pain in women with uterine leiomyomas and heavy menstrual bleeding.

Methods: Two replicate, multinational, double-blind, 24-week, randomized, phase 3 studies (LIBERTY 1 and 2) were conducted in premenopausal women with uterine leiomyoma-associated heavy menstrual bleeding (80 mL or greater per cycle for two cycles or 160 mL or greater during one cycle).

Background: Intermediate nerve neuralgia is a rare type of cranial neuralgia that causes clinical, therapeutic, and diagnostic challenges. Studies have described pharmacological and surgical treatment options. Surgical treatment ranges from sectioning of neural structures to microvascular decompression.

Article Synopsis
  • Uterine fibroids cause significant menstrual bleeding and pain, and a new treatment approach using relugolix combined with estradiol and norethindrone acetate may offer a solution without lowering estrogen levels.
  • In two international phase 3 trials, women were randomized to receive either the relugolix combination therapy, placebo, or delayed therapy, with the main goal being to see how many had reduced menstrual blood loss and related symptoms.
  • Results showed that 71-73% of women on the combination therapy reported improvement, compared to only 15-19% in the placebo group, with additional benefits seen across several secondary measures, highlighting the efficacy of this treatment for managing symptoms related to uterine fibroids.

Article Synopsis
  • Antibiotic resistance in gram-negative bacteria is significantly increasing, highlighting the need for new prevention strategies.
  • A study developed a vaccine targeting FimH, a protein involved in bacterial adhesion, to prevent recurrent urinary tract infections (UTIs).
  • The phase 1 trial involved 67 healthy women and showed that the vaccine was safe, well-tolerated, and induced strong antibody responses, leading to plans for further phase 2 testing.

This article reports on 3-year clinical outcomes of the Sonography Guided Transcervical Ablation of Uterine Fibroids (SONATA) pivotal trial of transcervical fibroid ablation (TFA) in women with symptomatic uterine myomata. The SONATA, prospective, controlled, multicenter interventional trial enrolled 147 premenopausal women with symptomatic uterine fibroids who underwent uterus-preserving, sonography-guided TFA with the Sonata System (Gynesonics, Inc., Redwood City, CA, USA).

Objective: To 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.

Methods: Women 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.

Purpose: To evaluate the efficacy of two cervical block protocols for pain management during hysteroscopic removal of intrauterine polyps and myomas using the MyoSure(®) device.

Patients And Methods: This was a randomized, comparative treatment trial conducted by five private Obstetrics and Gynecology practices in the USA. Forty premenopausal women aged 18 years and older were randomized to receive either a combination para/intracervical block protocol of 37 cc local anesthetic administered at six injections sites in association with the application of topic 1% lidocaine gel, or an intracervical block protocol of 22 cc local anesthetic administered at three injections sites without topical anesthetic, for pain management during hysteroscopic removal of intrauterine polyps and/or a single type 0 or type 1 submucosal myoma ≤3 cm.
