Elagolix Cuts Heavy Menstrual Bleeding in Women With Fibroids

In continuation of my update on elagolix

For women with uterine fibroids, elagolix with add-back hormonal therapy is associated with a reduction in heavy menstrual bleeding compared with placebo, according to a study published in the Jan. 23 issue of the New England Journal of Medicine.

William D. Schlaff, M.D., from Thomas Jefferson University in Philadelphia, and colleagues conducted two randomized, placebo-controlled phase 3 trials (Elaris Uterine Fibroids 1 and 2 [UF-1 and UF-2]) to assess the efficacy and safety of elagolix twice daily with hormonal add-back therapy to replace reduced levels of endogenous hormones. Overall, 412 women in UF-1 and 378 in UF-2 were randomly assigned in a 2:1:1 ratio to receive elagolix with add-back therapy, elagolix alone, or placebo. The primary end point was menstrual blood loss <80 mL in the final month of treatment and ≥50 percent reduction in menstrual blood loss from baseline to the final month.
The researchers found that in UF-1 and UF-2, the criteria for the primary end point were met by 68.5 percent of 206 and 76.5 percent of 189 women, respectively, who received elagolix plus add-back therapy, compared with 8.7 percent of 102 and 10 percent of 94 women, respectively, who received placebo. The primary end point was met by 84.1 percent of 104 women and 77 percent of 95 women in UF-1 and UF-2, respectively, who received elagolix alone. With add-back therapy, hypoestrogenic effects of elagolix were attenuated.
"In both trials reported here, the risk of heavy menstrual bleeding among premenopausal women with uterine fibroids was significantly lower among women who received elagolix," the authors write.
Several authors disclosed financial ties to biopharmaceutical companies, including AbbVie, which manufactures elagolix and funded the study.

A novel pill to treat bleeding from uterine fibroids aims for FDA approval


In continuation of my update on elagolix

A new drug called elagolix cut blood loss by half over six months in the overwhelming majority of  who participated in two clinical trials published Wednesday in the New England Journal of Medicine.
Elagolix, being developed by AbbVie, was approved by the U.S. Food and Drug Administration in 2018 under the brand name Orilissa to reduce the pain of endometriosis—another common, debilitating female disorder.
The fibroid studies, conducted at 77 sites in the United States and Canada, were led by William D. Schlaff, the chair of obstetrics and gynecology at Thomas Jefferson University in Philadelphia. The results have been submitted to the FDA, which is expected to issue its decision in the first half of 2020.
Elagolix works by suppressing the gonadotropin  and the ovarian sex hormones, estrogen and progesterone. In effect, it throws women into a temporary menopause.
Because this suppression can cause , the researchers gave a subset of women low doses of sex hormones along with elagolix. Of those 395 women, about 70% cut their blood loss by half without suffering more bone thinning than women taking a placebo. The "add-back" hormones also reduced menopausal side effects such as hot flashes and night sweats, although these remained common.
"As a clinician working with patients like this for 40 years, I think this is a valuable clinical tool," Schlaff said of elagolix and add-back hormones. "It's oral, the effect is fast onset, and the side-effect profile is tolerable."
The brand name and pricing that would be used if the FDA approves this use of elagolix have not yet been established for the drug, an AbbVie spokesperson said. The list price for a four-week supply of Orilissa is $907.39.
An estimated 80% of women approaching menopause have fibroids—muscular growths in the uterine wall. Half of those women will develop symptoms, primarily heavy menstrual bleeding, which can lead to a blood iron deficiency. Charlotte Owens, medical director at AbbVie, noted that African American women have a higher risk for  and often develop more severe symptoms than Caucasian women.
After menopause, when the ovaries shut down, menstrual bleeding stops, but many women find the transitional bleeding so troublesome that they seek treatment.
Current options—including drugs that target hormones, procedures that destroy the uterine lining or surgical removal of the fibroids or entire uterus—all have drawbacks. A device called an electric morcellator, which minces fibroids and removes the tissue through tiny incisions, has been largely abandoned because in rare cases it can disseminate an undetected uterine cancer. Philadelphia cardiac surgeon Hooman Noorchashm and his late wife, anesthesiologist Amy Reed, campaigned for a ban on morcellators after her cancer was spread during a hysterectomy.
Existing gonadotropin hormone-suppressing drugs, including one approved in 1989 that Schlaff helped to test in patients, have to be given as injections and take up to two weeks to begin working.
Other companies besides AbbVie have been working to tap the potentially huge market of women with fibroid-related bleeding. A few years ago, Allergan seemed to be in the lead with ulipristal acetate, brand name Esmya, which was already approved in Europe. But after European regulators initiated an investigation into whether the drug led to liver damage in some patients, the FDA declined to approve it.
Myovant Sciences' relugolix, which reduced blood loss in nearly three-quarters of patients in the second of two late-stage clinical trials, is also seeking approval for the  in combination with add-back hormone medications.

FDA Approves Orilissa (elagolix) for the Management of Moderate to Severe Pain Associated with Endometriosis

In continuation of my update on elagolix


AbbVie a research-based global biopharmaceutical company, in cooperation with Neurocrine Biosciences, Inc. , announced that the U.S. Food and Drug Administration (FDA) approved Orilissa (elagolix), the first and only oral gonadotropin-releasing hormone (GnRH) antagonist specifically developed for women with moderate to severe endometriosis pain. The FDA approved Orilissa under priority review. Orilissa represents the first FDA-approved oral treatment for the management of moderate to severe pain associated with endometriosis in over a decade and is expected to be available in U.S. retail pharmacies in early August 2018.

"Orilissa represents a significant advancement for women with endometriosis and physicians who need more options for the medical management of this disease," said Michael Severino, M.D., Executive Vice President, Research and Development and Chief Scientific Officer, AbbVie. "The approval of Orilissa demonstrates AbbVie's continued commitment to address serious diseases and unmet needs."
Endometriosis is one of the most common gynecologic disorders in the U.S.3 It affects an estimated one in 10 women of reproductive age and can be associated with pain symptoms that can be debilitating.3,4 Women can suffer for up to six to 10 years and visit multiple physicians before receiving a proper diagnosis.5,6
Endometriosis-associated pain is often managed with medicines such as oral contraceptives, nonsteroidal anti-inflammatory drugs (NSAIDs), opioids and hormonal therapies, which can work for some women but very few are specifically indicated for the treatment of endometriosis.3,7 In more extensive cases, surgical interventions (e.g., laparotomy, laparoscopy or hysterectomy) are often pursued, and may not be curative for all individuals.8
"Endometriosis is often characterized by chronic pelvic pain that can impact women's daily activities," said Hugh S. Taylor, M.D., study investigator and Chair of the Department of Obstetrics, Gynecology and Reproductive Sciences, Yale School of Medicine. "Women with endometriosis may undergo multiple medical treatments and surgical procedures seeking pain relief and this approval gives physicians another option for treatment based on a woman's specific type and severity of endometriosis pain."
The approval is supported by data from two replicate studies in the largest endometriosis Phase 3 study program conducted to date, which evaluated nearly 1,700 women with moderate to severe endometriosis pain. Clinical trial data demonstrated Orilissa significantly reduced the three most common types of endometriosis pain: daily menstrual pelvic pain, non-menstrual pelvic pain and pain with sex. A higher proportion of women treated with Orilissa 150 mg once daily and 200 mg twice daily were responders for daily menstrual pain and non-menstrual pelvic pain compared to placebo in a dose-dependent manner at month three. Women were defined as responders if they experienced a reduction in daily menstrual pain and non-menstrual pelvic pain with no increase in analgesic use (nonsteroidal anti-inflammatory drug or opioid) for endometriosis-associated pain.
Both Orilissa treatment groups showed statistically significant greater mean decreases from baseline compared to placebo in daily menstrual pain and non-menstrual pelvic pain at month six. Women in the Phase 3 studies also provided a daily self-assessment of their endometriosis pain using a numeric rating scale (NRS) and women taking Orilissa 150 mg once daily and 200 mg twice daily reported a statistically (p <0.001) significant reduction from baseline in NRS scores compared to placebo at month three. Clinical trial data also demonstrated women taking Orilissa 200 mg twice daily showed statistically significant greater reduction in pain with sex from baseline to month three compared to placebo.
The recommended duration of use for Orilissa is up to 24 months for the 150 mg once daily dose and up to six months for the 200 mg twice daily dose, as it causes a dose-dependent decrease in bone mineral density (BMD). BMD loss is greater with increasing duration of use and may not be completely reversible after stopping treatment. For women with moderate hepatic impairment, the recommended dosage is 150 mg once daily for up to six months. Orilissa is recommended to be taken orally at approximately the same time each day, with or without food.
"Together with AbbVie, we are proud to offer a treatment option for the many women suffering from pain associated with endometriosis," said Kevin Gorman, Ph.D., Chief Executive Officer of Neurocrine Biosciences. "Neurocrine discovered Orilissa nearly twenty years ago and through our partnership with AbbVie, the approval of Orilissa reflects our joint commitment to develop therapies for difficult to manage conditions in underserved patient populations."

Phase 3 Elagolix Trial Begins | News | Drug Discovery and Development Magazine

Elagolix (see structure) is an oral gonadotropin-releasing hormone (GnRH) antagonist. "Endometriosis can be a debilitating disease that affects millions of women around the world and the exploration of new treatments could offer other options for women with this disease," said Dr. Hugh Taylor, M.D., Chief of Division of Reproductive Endocrinology and Infertility, Yale School of Medicine.

The Phase 3 trial (M12-665) is a 24-week, multinational, randomized, double-blind, placebo-controlled study designed to evaluate the safety and efficacy of elagolix in 875 women, age 18 to 49, with moderate-to-severe endometriosis-associated pain. It will be conducted at approximately 160 sites in the United States, Puerto Rico and Canada.
"The investigation of elagolix for endometriosis is an important step in the exploration of potential treatments for this underserved patient population," said Rita Jain, M.D., divisional vice president, Pain, Respiratory and Metabolic Development, Global Pharmaceutical R&D, Abbott.

The trial has begun screening for enrollment. A second Phase 3 study is planned with an NDA filing targeted in 2016.
