Nestorone (segesteroneacetate) effects on neuroregeneration. Nestorone® (segesteroneacetate) is a progestin with a chemical structure closely related to progesterone with high affinity and selectivity for the progesterone receptor without significant interaction with other steroid receptors. It has been developed for female and male contraception and is FDA-approved in a first long-acting

Design of an International Male Contraceptive Efficacy Trial Using a Self-Administered Daily Transdermal Gel Containing Testosterone and SegesteroneAcetate (Nestorone®). Injectable male hormonal contraceptives are effective for preventing pregnancy in clinical trials; however, users may prefer to avoid medical appointments and injections. A self-administered transdermal contraceptive gel may combined testosterone and segesteroneacetate (Nestorone®™) gel for male contraception. The transdermal approach to male contraception raises novel considerations regarding adherence with the daily gel, as well as concern about the potential transfer of the gel and the contraceptive hormones to the female partner. Enrolled couples are in committed relationships. Male partners have baseline normal
The use of serum segesteroneacetate levels to assess adherence of trial participants with a contraceptive vaginal ring. To determine the incidence of out-of-range segesteroneacetate (NES) concentrations in participants of a pharmacokinetic/pharmacodynamic trial of a continuous use contraceptive vaginal ring (CVR) releasing NES and estradiol (E2). We hypothesized that out-of-range

Dose-finding study of a 90-day contraceptive vaginal ring releasing estradiol and segesteroneacetate. To evaluate serum estradiol (E2) concentrations during use of 90-day contraceptive vaginal rings releasing E2 75, 100, or 200 mcg/day and segesteroneacetate (SA) 200 mcg/day to identify a dose that avoids hypoestrogenism. We conducted a multicenter dose-finding study in healthy, reproductive median unscheduled bleeding or spotting days. Estradiol concentrations with rings releasing E2 200 mcg/day and SA 200 mcg/day avoid hypoestrogenism over 30-day use. A 90-day contraceptive vaginal ring releasing estradiol 200 mcg/day and segesteroneacetate 200 mcg/day achieves estradiol concentrations that should avoid hypoestrogenism and effectively suppresses ovulation.
Simultaneous assay of segesteroneacetate (Nestorone®), estradiol, progesterone, and estrone in human serum by LC-MS/MS. To develop a method to simultaneously quantify the synthetic contraceptive progestin segesteroneacetate (Nestorone®, NES) and the endogenous steroid hormones estradiol (E2), progesterone (P4), and estrone (E1) in human serum samples by liquid chromatography-tandem mass
Bleeding profile associated with 1-year use of the segesteroneacetate/ethinyl estradiol contraceptive vaginal system: pooled analysis from Phase 3 trials. To describe bleeding patterns among users of the segesteroneacetate (SA) and ethinyl estradiol (EE) contraceptive vaginal system (CVS), and identify factors associated with unscheduled bleeding/spotting (B/S). We pooled results from two
Segesteroneacetate/Ethinyl estradiol 12-month contraceptive vaginal system safety evaluation. To evaluate safety outcomes from clinical studies of a 12-month contraceptive vaginal system (CVS) releasing an average of segesteroneacetate (SA) 150 mcg and ethinyl estradiol (EE) 13 mcg daily. We integrated clinical safety data from nine studies in which women used the CVS for 21 consecutive days
Efficacy of the 1-year (13-cycle) segesteroneacetate and ethinylestradiol contraceptive vaginal system: results of two multicentre, open-label, single-arm, phase 3 trials. A ring-shaped, contraceptive vaginal system designed to last 1 year (13 cycles) delivers an average of 0·15 mg segesteroneacetate and 0·013 mg ethinylestradiol per day. We evaluated the efficacy of this contraceptive vaginal system and return to menses or pregnancy after use. In two identically designed, multicentre, open-label, single-arm, phase 3 trials (one at 15 US academic and community sites and one at 12 US and international academic and community sites), participants followed a 21-days-in, 7-days-out segesteroneacetate and ethinylestradiol contraceptive vaginal system schedule for up to 13 cycles.

Therapeutic progestin segesteroneacetate promotes neurogenesis: implications for sustaining regeneration in female brain. Neurogenesis is the principal regenerative mechanism to sustain the plasticity potential in adult brains. Decreased neurogenesis parallels the cognition decline with aging, and has been suggested as a common hallmark in the progression of many neurodegeneration diseases. We previously reported that acute exposure to segesteroneacetate (ST-1435; Nestorone), alone or in combination with 17β-estradiol (E2), increased human neural stem cells proliferation and survival both in vitro and in vivo. The present study expanded our previous findings to investigate the more clinical related chronic exposure in combination with E2 on the regenerative capacity of adult brain. To mimic
Effects of concurrent vaginal miconazole treatment on the absorption and exposure of Nestorone® (segesteroneacetate) and ethinyl estradiol delivered from a contraceptive vaginal ring: A randomized, crossover drug-drug interaction study. To evaluate the effects of concurrent administration of three vaginal miconazole nitrate formulations on the absorption and exposure of Nestorone® (segesteroneacetate) and ethinyl estradiol from a novel contraceptive vaginal ring (NES/EE CVR). This was an open-label, randomized, crossover, drug-drug interaction study conducted over three menstrual cycles in healthy women with regular menses. We compared systemic exposure to NES and EE by determining area under the curve (AUC) with CVR only and CVR with each miconazole treatment. Three different miconazole
The Effects of Annovera™ and Tampon Co-Usage on the Pharmacokinetics of SegesteroneAcetate and Ethinyl Estradiol This study will evaluate the effect of Annovera and tampon co-usage on the pharmacokinetics (PK) of segesteroneacetate (SA) and ethinyl estradiol (EE). This is an open label, randomized, crossover PK study. Participants will be randomized to one of two treatment sequences. Each
to decreased effectiveness and a higher risk of VTE [36]. While the evidence is limited, clinicians should counsel patients regarding the potential for decreased ef-fectiveness of and increased risk of VTE from the contraceptive patch in pregnant-capable people with a BMI of 30 kg/m2 or higher.Etonogestrel (ENG)/ethinyl estradiol (EE) and segesteroneacetate/ ethinyl estradiol (EE) contraceptive vaginal rings. Similarly, a pro-spective study including 20 pregnant-capable people with a BMI of 30 kg/m2 or higher using the ENG/EE contraceptive vaginal ring found that these individuals had lower serum EE levels but still had sup-pression of ovarian follicular development similar to that of pregnant- capable people with a BMI of 18.5–24.9 kg/m2 [37]. Clinical trials for the segesteroneacetate/EE
30. A newer vaginal ring containing 103 mg segesteroneacetate and 17.4 mg ethinyl estradiol (releases 0.15 mg/day of segesteroneacetate and 0.013 mg/day ethinyl estradiol) was FDA-approved in 2018. Unlike the traditional ring that is designed for one-time use, the newer ring is reusable and lasts for 1 year. Currently, data on use for prolonged menstrual suppression are available only on the management of unscheduled bleeding, see Table 2. Further ResearchGaps in research include limited studies specifically addressing rates of amenorrhea with hormonal therapy, particularly with non–FDA-approved use such as extended and continuous cycling. Newer methods of hormonal therapy, including the drospirenone-only pill and segesteroneacetate and ethinyl estradiol vaginal system, have limited data
and contraception. A transdermal gel delivering Nestorone (segesteroneacetate) and testosterone is under development and is leading the way in advancing novel, self-delivered methods of male hormonal contraception.
