Adherence with ethinylestradiol 20 ?g/drospirenone 3 mg in a flexible extended regimen supported by the use of a digital tablet dispenser with or without acoustic alarm: an open-label, randomized, multicenter study.

ABSTRACT: OBJECTIVE:To evaluate the effect of a digital dispenser's acoustic alarm function on adherence to ethinylestradiol (EE) 20 ?g/drospirenone 3 mg in a flexible extended regimen (EE/drospirenoneFlex) among women in five European countries (France, Germany, Italy, Spain, UK) seeking oral contraception. STUDY DESIGN:Randomized, parallel-group open-label study. METHODS:Women aged 18-35 years received EE/drospirenoneFlex administered in a regimen with cycle lengths of their choice with the aid of a digital pill dispenser over 1 year. In group A (N=250), the dispenser's acoustic alarm was activated (ie, acoustic alarm + visual reminder). In group B (N=249), the acoustic alarm was deactivated (ie, visual reminder only). In addition, the women recorded pill intake daily in diary cards. The primary efficacy variable was the mean delay of daily pill release after the dispenser reminded the woman to take a pill (reference time). Secondary efficacy variables included number of missed pills, contraceptive efficacy, bleeding pattern, tolerability, and user satisfaction. RESULTS:Dispenser data showed a mean (standard deviation [SD]) daily delay in pill release of 88 (126) minutes in group A vs 178 (140) minutes in group B (P<0.0001). Median (lower quartile, Q1; upper quartile, Q3) number of missed pills was 0 (0; 1) in group A vs 4 (1; 9) in group B (P<0.0001). Diary card results revealed similar trends; however, underreporting of missed pills was evident in both groups. No pregnancies were reported during 424 women-years of exposure. Across the two groups, the mean (SD) EE/drospirenoneFlex cycle length was 51.0 (31.8) days with strong regional differences, and the mean (SD) number of bleeding/spotting days was 50.4 (33.0) days. EE/drospirenoneFlex was well tolerated, and 80% of women were satisfied with treatment. CONCLUSION:The dispenser's activated acoustic alarm improved adherence with daily tablet intake of EE/drospirenoneFlex, reducing missed pills. EE/drospirenoneFlex provided effective contraception and a good tolerability profile.

Project description:The contraceptive efficacy and tolerability of a new flexible extended regimen of ethinylestradiol (EE) 20 ?g/drospirenone (DRSP) 3 mg to extend the menstrual cycle and enable management of intracyclic (breakthrough) bleeding (flexible(MIB)) was investigated and the bleeding pattern compared with a conventional 28-day regimen and a fixed extended 124-day regimen.This Phase III, 2-year, multicentre, open-label study randomly (4:1:1) allocated women (aged 18-35 years) to the following regimens: flexible(MIB) (24-120 days' active hormonal intake with 4-day tablet-free intervals); conventional (24 days' active hormonal intake followed by a 4-day hormone-free interval); or fixed extended (120 days' uninterrupted active hormonal intake followed by a 4-day tablet-free interval). Primary outcomes included the number of bleeding/spotting days during Year 1 (all regimens) and the number of observed unintended pregnancies over 2 years (flexible(MIB) only).Results were analysed in 1067 women (full analysis set). The mean number of bleeding/spotting days was lower with the flexible(MIB) vs the conventional regimen [41.0±29.1 (95% CI 38.8-43.3) vs 65.8±27.0 (95% CI 62.2-69.4) days, p<0.0001; treatment difference -24.8 (95% CI -29.2 to -20.3) days]. The corresponding value for the fixed extended regimen was 60.9±51.1 (95% CI 53.9-67.9) days. The Pearl Index for the flexible(MIB) regimen was 0.64 (95% CI 0.28-1.26). All regimens had comparable tolerability profiles.EE 20 ?g/DRSP 3 mg administered as a flexible extended regimen with MIB is effective, well tolerated and is associated with statistically significantly fewer bleeding/spotting days and fewer withdrawal bleeding episodes vs EE/DRSP in a conventional 28-day regimen. The flexible(MIB) also provided statistically significantly fewer spotting days vs EE/DRSP in a fixed extended 124-day regimen (post hoc evaluation). The flexible(MIB) regimen allows women to extend their menstrual cycle and manage their intracyclic (breakthrough) bleeding.

Project description:BackgroundDysmenorrhea is a common condition in women, which is characterized by menstrual pain. Low-dose estrogen/progestin combined oral contraceptives have been shown to reduce the severity of dysmenorrhea symptoms, and a 28-day cyclic regimen of ethinylestradiol/drospirenone (28d regimen) is approved for this indication in Japan.AimThe aim of this study was to assess the safety and efficacy of a flexible extended regimen of ethinylestradiol/drospirenone (flexible regimen) in Japanese women with dysmenorrhea.MethodsThis multicenter, open-label study was performed in Japanese women with dysmenorrhea who, after a baseline observational phase, were randomized to receive ethinylestradiol 20 μg/drospirenone 3 mg in a flexible regimen (one tablet each day for 24-120 days followed by a 4-day tablet-free interval) or in the standard 28d regimen (one tablet each day for 24 days, followed by 4 days of placebo tablets for six cycles). The primary endpoint was the number of days with dysmenorrhea of at least mild intensity over a 140-day evaluation period. Dysmenorrhea scores, bleeding patterns, and other pain-related parameters were also assessed.ResultsA total of 216 women (mean age 29.7 years) were randomized to the flexible regimen (n=108) or 28d regimen (n=108) and 212 were included in the full analysis sets (flexible regimen, n=105; 28d regimen, n=107). Women in the flexible-regimen group reported a mean of 3.4 fewer days with dysmenorrheic pain than women in the 28d-regimen group, with similar decreases in disease severity reported in both treatment groups. According to the investigators, 64.8% and 59.4% of women in the flexible-regimen and 28d-regimen treatment groups had "very much improved" or "much improved" disease, while 54.3% and 50.9% of patients reported being "very much satisfied" or "much satisfied" with their treatment, respectively.ConclusionIn Japanese women with dysmenorrhea, a flexible extended regimen of ethinylestradiol/drospirenone decreased the number of days with dysmenorrheic pain versus the traditional 28d regimen.

Project description:IntroductionDysmenorrhea and endometriosis are common gynecologic disorders among women of reproductive age that significantly impact health-related quality of life (HRQL) as well as productivity. Although there are treatment options listed in Japanese guidelines, a gap remains in unmet medical needs for maximizing treatment outcome. The extended regimen of ethinylestradiol and drospirenone (EE/DRSP) (taken daily for up to 120 consecutive days) has been available in Japan for treating dysmenorrhea and/or endometriosis-associated pain since 2016. Yet, the effectiveness of its usage on HRQL has not been investigated elsewhere to date. Therefore, in this study, we aim to observe changes in HRQL of Japanese women treated with an extended regimen of EE/DRSP for dysmenorrhea and/or endometriosis-associated pain.MethodsAs part of a 2-year post-marketing surveillance study, women with dysmenorrhea or endometriosis-associated pelvic pain were prescribed extended EE/DRSP during routine clinical practice. Data were collected 1 month before and 3 and 6 months after initiating treatment. Primary outcomes were the Menstrual Distress Questionnaire (MDQ) (before, during, and after menstruation) in patients with dysmenorrhea, and the Endometriosis Impact Scale (EIS) and European Quality of Life 5-dimensions 5-level instrument (EQ-5D-5L) in patients with endometriosis.ResultsThe study cohort included 315 patients (mean age 28.9 years) with dysmenorrhea and 262 patients (mean age 31.3 years) with endometriosis. Mean MDQ total scores before and during menstruation decreased significantly after 6 months with extended EE/DRSP; there was no improvement in after-menstruation MDQ score. Mean EIS domain scores improved significantly by 6 months, with improvement in most EIS individual item scores. Mean EQ-5D-5L scores increased slightly during 6 months of treatment.ConclusionsExtended EE/DRSP treatment improved HRQL outcomes in Japanese women with dysmenorrhea or endometriosis-associated pelvic pain.Trial registrationRegistered at ClinicalTrials.gov (NCT03126747) on June 2017.

Project description:BACKGROUND:The Clyk™ digital pill dispenser helps ensure correct and consistent administration of a flexible extended regimen of the combined oral contraceptive, ethinylestradiol (EE) 20 ?g/drospirenone 3 mg (EE/drospirenone ; YAZ(®) Flex Flex), guiding users through the intake cycle and 4-day pill break and providing visible and acoustic daily reminders when pill intake is due. A study showed that the audible alarm function of the dispenser could help reduce the number of missed pills, but it lacked an appropriate "non-dispenser" group for a meaningful assessment of the impact of the dispenser on adherence. This study indirectly assessed the overall effect of the digital dispenser on adherence by comparing data from a treatment with standard blister packaging. MATERIALS AND METHODS:One-year adherence data were compared from two similarly designed, Phase III, open-label, randomized trials of EE/drospirenoneFlex. In study 1, women used diary cards to record adherence with EE/drospirenoneFlex dispensed in blister packs (n=640), and in study 2 the dispenser was used with the alarm activated (n=250) or deactivated (n=248) in addition to using diary cards. RESULTS:A mean (±SD) of 4.3 (±4.24) missed pills over 1 year were recorded in diary cards among women who dispensed their pills from the blister packages (study 1) compared with 1.0 (±2.4) recorded by the alarm-activated dispenser (study 2). In study 2, a mean of 1.9 (±4.2) missed pills were reported in the diaries over 1 year compared with 4.4 (±9.1) from automatic recording by the dispenser (both arms of study 2), indicating underreporting of missed pills in diary cards vs the digital dispenser. Adjusting for this rate of underreporting, an estimated mean of ten pills were missed over 1 year by women using EE/drospirenoneFlex in blister packs, or ten times more than with the digital dispenser with activated acoustic alarm. CONCLUSION:The digital dispenser helps reduce the number of missed pills and increases adherence.
