Daré Bioscience Announces Publication in Menopause: The Journal of The North American Menopause Society of Data from Phase 1/2 Open-Label Safety and Pharmacokinetics Study of DARE-HRT1 in Healthy Postmenopausal Women
Daré Plans to Advance DARE-HRT1 into Single Phase 3 Efficacy Trial for Treatment of Vasomotor Symptoms (VMS) due to Menopause
DARE-HRT1 has the potential to be the first FDA-approved monthly intravaginal ring delivering both estrogen and progestogen hormone therapy
The article, titled “A phase 1/2, open-label, parallel group study to evaluate the safety and pharmacokinetics of DARE-HRT1 (80 μg estradiol/4 mg progesterone and 160 μg estradiol/8 mg progesterone intravaginal rings) over 12 weeks in healthy postmenopausal women,” is available online through both the Latest Articles section of the Menopause journal’s website, as well as the Scientific & Clinical Publications section of Daré’s website, and will be published in Volume 30, Issue 8 of Menopause.
The study enrolled a total of 21 subjects, who were randomized (1:1) to receive one of two versions of DARE-HRT1, either IVR1 (E2 80 μg/d with P4 4 mg/d) or IVR2 (E2 160 μg/d with P4 8 mg/d), and used DARE-HRT1 over 12 weeks (three 28-day cycles). The study results demonstrated both versions of DARE-HRT1 were safe and released E2 in systemic concentrations in the low, normal premenopausal range and P4 in systemic concentrations predictive of endometrial protection. Data from the study support continued clinical development of DARE-HRT1 for the treatment of menopausal symptoms.
Daré previously reported positive topline data from the Phase 1/2 study of DARE-HRT1 in
DARE-HRT1 has the potential to be the first FDA-approved product to offer vaginal delivery of combination bio-identical estradiol and bio-identical progesterone therapy in a convenient monthly format. Daré plans to advance DARE-HRT1 into a single Phase 3 clinical trial to support a new drug application for DARE-HRT1 for the treatment of moderate to severe VMS due to menopause in women with intact uteri.
“The clinical and quality of life issues associated with menopause continue to take center stage as women and healthcare providers increasingly appreciate the need for more treatment options. We are excited to have the results of our Phase 1/2 study published in this prestigious peer-reviewed journal and we believe the study results underscore DARE-HRT1’s compelling therapeutic value proposition and its potential to be a first-in-category non-oral and convenient non-daily option for women suffering from vasomotor symptoms associated with menopause, such as hot flashes and night sweats,” said
DARE-HRT1 505(b)(2) Regulatory Pathway
Following clinical development, Daré intends to leverage the existing safety and efficacy data on the active ingredients in DARE-HRT1, estradiol and progesterone, to utilize the
Daré intends to seek FDA approval of DARE-HRT1 for the treatment of moderate to severe VMS due to menopause in women with intact uteri. Based on pre-IND communications with the FDA and the topline PK data from the DARE-HRT1 Phase 1 / 2 study, Daré believes FDA approval of DARE-HRT1 for that indication is achievable via the 505(b)(2) pathway supported by a single, placebo-controlled, Phase 3 clinical trial of DARE-HRT1 and a scientifically justified PK “bridge” (via a relative bioavailability trial) between DARE-HRT1 and the selected listed estradiol and progesterone drugs. Ongoing activities to support progressing directly into a single Phase 3 study to support registration include manufacturing and non-clinical studies to support the IND submission and the planned IND-opening Phase 3 study.
About Menopause
Menopause is defined as the final menstrual period and is typically confirmed after a woman has missed her period for 12 consecutive months. Most women experience menopause between ages 40 and 58.1 An estimated 45 million women in the U.S. are approaching or in menopause, which results in a decrease in estrogen and other hormones.1,2 Hot flashes, vaginal dryness and loss of bone density are frequently associated with menopause. Night sweats (hot flashes that occur during sleep) often cause sleep disturbance, and vaginal atrophy (the drying and thinning of vaginal tissues) can cause a feeling of vaginal tightness during sex along with pain, burning, or soreness.1 Hence, management of menopausal symptoms can impact quality of life, productivity and health. The North American Menopause Society (NAMS) believes that hormone therapy is the most effective treatment for VMS and the genitourinary syndrome of menopause and observes that a non-oral route may offer potential advantages over oral routes of administration because non-oral routes bypass the first-pass hepatic effect.2
