Trial Outcomes & Findings for Study to Evaluate Ospemifene in Patients With Moderate to Severe Vaginal Dryness Due to Menopause (NCT NCT02638337)

NCT ID: NCT02638337

Last Updated: 2019-04-02

Results Overview

Parabasal cells are immature squamous cells in the lining of the vagina. A predominance of parabasal cells indicates absence of estrogenic stimulation and vaginal atrophy. Vaginal smear samples were taken from the middle third of the lateral vaginal wall and were evaluated at a central laboratory by a qualified pathologist. A decrease in parabasal cells indicates improvement in vaginal atrophy. To calculate least squares (LS) means, a mixed-effects model for repeated measures (MMRM) model was used.

Participant Flow

Participants were randomized at 68 sites in the United States.

After a screening period of up to 4 weeks, participants who met all eligibility criteria were randomized in a 1:1 ratio to receive either ospemifene 60 mg once daily or matching placebo for 12 weeks. Randomization was stratified by severity of most bothersome symptom of vaginal dryness on Day 1 and by the presence or absence of the uterus.

Superficial cells are mature squamous cells in the lining of the vagina that can decrease in number after menopause resulting in vulvovaginal atrophy. Vaginal smear samples were taken from the middle third of the lateral vaginal wall and were evaluated at a central laboratory by a qualified pathologist. An increase in the number of superficial cells indicates improvement in atrophy. To calculate least squares (LS) means, a mixed-effects model for repeated measures (MMRM) model was used.

The pH scale ranges from 0 to 14. A pH of 7 is neutral, less than 7 is acidic, and greater than 7 is basic. A typical vaginal pH in women of reproductive age is between 3.5 and 4.5, increasing to \> 4.5 after menopause. Vaginal pH was measured by the investigator using a pH indicator strip at the middle third of the vaginal wall. To calculate least squares (LS) means, a mixed-effects model for repeated measures (MMRM) model was used.

PRIMARY outcome

Timeframe: From the first dose of study drug up to 14 days after the last dose; 14 weeks

Population: Participants who received at least 1 dose of study drug. Four participants randomized to placebo received ospemifene in error and are counted in the ospemifene group for safety assessments. One participant randomized to placebo who enrolled at 2 different sites at the same time was excluded.

Treatment-related adverse events (AEs) were defined as AEs that were considered by the investigator to be related to investigational medicinal product, for which causal relationship with the study drug could be reasonably explained. A serious adverse event (SAE) is defined as any AE occurring at any dose that resulted in any of the following outcomes: * Death * Life-threatening condition * Hospitalization or prolongation of existing hospitalization for treatment * Persistent or significant disability/incapacity * Congenital anomaly/birth defect * Other medically important conditions that, based on medical judgment, may jeopardize the participant's health and may require medical intervention to prevent one of the outcomes listed above.

The maturation value is an indicator of the level of maturation attained by the vaginal epithelium. Vaginal smear samples were taken from the middle third of the lateral vaginal wall and were evaluated at the central laboratory by a qualified pathologist. Parabasal cells (P), intermediary cells (I), and superficial cells (S) were counted and results were expressed as the maturation value (MV), whereby superficial cells were assigned a point value of 1.0, intermediate cells were assigned a point value of 0.5, and parabasal cells were assigned a point value of 0. The maturation value (MV) was defined as: (percentage of superficial cells \* 1) + (percentage of intermediate cells \* 0.5) + (percentage of parabasal calls \* 0). Lower MV indicates lower estrogen effect.

The investigator performed an evaluation of the vagina, assessing overall elasticity, fluid secretion, pH, condition of epithelial mucosa, and moisture. The severity of each characteristic was assessed using a 5-grade scale from 1 (worst) to 5 (best). The total score was calculated as the sum of the 5 individual scores and ranges from 5 to 25, where higher scores indicate better vaginal health

The investigator performed a visual examination of the vulva, assessing the labia majora, labia minora, clitoris, introitus appearance and elasticity, color, discomfort and pain, and presence of other findings (eg, petechiae, excoriations, ulcers, etc). The severity of each characteristic was assessed on a 4-point scale as 0 = normal, 1 = mild, 2 = moderate, and 3 = severe. The total score was calculated by adding the 7 individual scores and ranges from 0 to 21, where lower scores indicate better vulvar health. A negative change from baseline indicates improvement.

Population: Intent-to-treat population; participants who agreed to participate in the optional vaginal imaging, and with available data at both time points were included.

Vulvovaginal imaging was performed by trained site personnel following a standard procedure. Photographs were assessed by an Independent Panel Review (IPR) in a blinded fashion. Nine parameters (labia majora, labia minora, clitoris, urethra, introitus and elasticity, color, erythema, moisture, and other findings (petechiae, excoriation, ulceration, etc.)) were evaluated on a scale from 0 (normal/none) to 3 (severe). The total score was calculated from the sum of the 9 individual scores and ranged from 0 to 27 with lower values indicating better vulvovaginal health; a negative change from baseline indicates improvement.

The Female Sexual Function Index consists of 19 questions organized into 6 domains (desire, arousal, lubrication, orgasm, satisfaction, and pain) answered by the participant on a 5-point scale from 1 to 5. Where relevant, some questions also include an option of 0 if a question is not applicable due to no sexual activity. Each domain score was calculated by adding the scores of each item in the domain and multiplying by a domain factor. The total score was calculated by summing each domain score and ranges from 2 to 36, with higher values indicating better sexual function.

Where relevant, some questions also include an option of 0 if not applicable due to no sexual activity. Each domain score was calculated by adding the scores of each item in the domain and multiplying by a domain factor. For all domains, higher values indicate better sexual function, according to the following: Desire (2 questions): domain score ranges from 1.2 to 6; Arousal (4 questions): domain score ranges from 0 to 6; Lubrication (4 questions): domain score ranges from 0 to 6; Orgasm (3 questions): domain score ranges from 0 to 6; Satisfaction (3 questions): domain score ranges from 0.8 to 6; Pain (3 questions): domain score ranges from 0 to 6.

The presence or absence of urinary symptoms was assessed using the Urinary Distress Inventory (UDI)-6. The symptoms include frequent urination, urine leakage related to the feeling of urgency, urine leakage related to physical activity, coughing, or sneezing, small amounts of urine leakage, difficulty emptying bladder, and pain and discomfort in the lower abdominal or genital area. If a symptom was present, participants were asked to assess the degree to which they were bothered by it on the following 4-point scale: 1. = present but doesn't bother her at all; 2. = present and bothers her slightly; 3. = present and bothers her moderately; 4. = present and bothers her greatly. The total score was calculated by adding the 6 scores together (Absent = 0), and ranges from 0 to 24, with lower values indicating less urinary distress.
