Comparisons and correlations of 1-month recall vs 24-hour recall in patient-reported outcomes of an exploratory, phase 2b, randomized, double-blind, placebo-controlled clinical trial of sildenafil cream, 3.6% for the treatment of female sexual arousal disorder.

BACKGROUND: Efficacy assessments in clinical trials of treatments for female sexual arousal disorder (FSAD) and other female sexual dysfunction (FSD) diagnoses rely on various patient-reported outcomes (PROs). AIMS: We sought to compare 1-month recall PRO measures among participants enrolled in a clinical trial who provided these data without (test population) vs with (control population) use of an at-home, 24-hour recall electronic diary (eDiary), capturing similar data. METHODS: Preplanned subset analysis as performed during a phase 2b, exploratory, randomized, placebo-controlled, double-blind study of sildenafil cream, 3.6% (sildenafil cream) among healthy premenopausal women with FSAD. Preliminary product efficacy was assessed via 1-month recall and 24-hour recall questionnaires. A subset of the participants, the Evaluation of Recall Subset [ERS] provided PROs via the 1-month recall instruments but did not provide data via the 24-hour recall eDiary. OUTCOMES: Responses to the 1-month recall instruments were compared among ERS (test) vs non-ERS (control) participants. Among the non-ERS population, correlations between 1-month and 24-hour recall endpoints were calculated. RESULTS: There were no significant differences in the study co-primary 1-month recall efficacy endpoints, the Arousal Sensation (AS) domain of the 28-item Sexual Function Questionnaire (SFQ28) and the Female Sexual Distress Scale - Desire, Arousal, Orgasm question 14, among ERS vs non-ERS participants during the initial 1-month no-drug run-in period or the 1-month single-blind placebo run-in period (P values > .47). Scores on these 1-month recall PROs continued to be similar after randomization for sildenafil cream (P values > .30) and placebo cream (P values > .20) assigned ERS and non-ERS participants during the 3-month double-blind dosing period. There were strong correlations between the SFQ28 AS and eDiary AS scores during the no-drug run-in (R = 0.79, P < .01) and the single-blind run-in (R = 0.73 P < .001). During the double-blind dosing period, the SFQ28 AS score continued to be highly correlated with the eDiary AS score among sildenafil cream users (R = 0.83; P < .001) and placebo cream users (R = 0.8; 2 P < .001). CLINICAL IMPLICATIONS: There was no evidence that 1-month recall PRO instruments introduce recall bias; assessing arousal sensations with 24-hour vs 1-month PRO instruments is similar and either method could be used to assess efficacy depending on study objectives. STRENGTHS AND LIMITATIONS: This preplanned subset analysis compared efficacy of PROs based on recall duration. While the subset was preplanned, the study was powered to detect significant differences in the primary efficacy objectives, not among this subset analyses. CONCLUSION: These data will be used in planning future efficacy assessments of sildenafil cream for FSAD. CLINICAL TRIAL REGISTRATION: This clinical trial was registered with ClinicalTrials.gov, NCT04948151.

Safety of topical sildenafil cream, 3.6% in a randomized, placebo-controlled trial for the treatment of female sexual arousal disorder.

BACKGROUND: There are currently no Food and Drug Administration-approved treatments for female sexual arousal disorder (FSAD), which is physiologically analogous to male erectile dysfunction. AIMS: The study sought to test the systemic and local genital safety of topical sildenafil cream, 3.6% (sildenafil cream) among healthy premenopausal women with FSAD and their sexual partners over a 12-week treatment period. METHODS: This was a phase 2b, exploratory, randomized, placebo-controlled, double-blind study of sildenafil cream among healthy premenopausal women with FSAD. Safety was assessed by the frequency and incidence of treatment-emergent adverse events (TEAEs) among participants and their sexual partners. Participants recorded the incidence of TEAEs in a daily eDiary (electronic diary). Sexual partners were contacted within 72 hours of each sexual event in which investigational product was used. All participants used placebo cream for 1 month, during a single-blind run-in period, and then if eligible, were randomized 1:1 to sildenafil cream or placebo cream. Participants used their assigned investigational product over a 12-week double-blind dosing period. They attended monthly follow-up visits, in which their eDiary TEAE data were reviewed by the study staff and graded for severity and relationship to study product. OUTCOMES: The frequency and incidence of TEAEs among participants and their sexual partners. RESULTS: During the 12-week double-blind dosing period, there were 78 TEAEs reported by 29 of 99 sildenafil-assigned participants and 65 TEAEs reported by 28 of 94 placebo-assigned participants (P = .76). All TEAEs were mild or moderate in severity. The most common treatment-related TEAE among active and placebo-assigned participants was application site discomfort. There were no differences in the number of treatment-related TEAEs among sildenafil cream vs placebo cream users (P > .99). Four sildenafil cream participants and 3 placebo cream participants discontinued the study due to TEAEs involving application site discomfort (P > .99). There were 9 TEAEs reported by 7 of 91 sexual partners exposed to sildenafil cream vs 4 TEAEs reported by 4 of 84 sexual partners exposed to placebo cream (P = .54). CLINICAL IMPLICATIONS: These data support further clinical development of topical sildenafil cream for the treatment of FSAD. STRENGTHS AND LIMITATIONS: Safety was assessed among participants and their sexual partners after 1357 and 1160 sexual experiences in which sildenafil cream or placebo cream were used, respectively. The phase 2b study was powered for the primary objectives of efficacy, rather than safety. CONCLUSION: These data demonstrate that topically applied sildenafil cream was safe and well tolerated by exposed users and their sexual partners.

A Qualitative Analysis of Low-Income Pregnant and Parenting Caregivers' Experiences With Home Visiting in California During the First 2 Years of the COVID-19 Pandemic.

CONTEXT: In-person home visiting programs that provide evidence-based parenting and child development support improve outcomes for low-income children and families. The COVID-19 pandemic led to a shift from primarily in-person to virtual home visiting services, and little is known about clients' experience of home visiting in this context. OBJECTIVE: To describe the experience of clients in the California Work Opportunity and Responsibility to Kids (CalWORKs) Home Visiting Program (HVP) across California during the first 2 years of the pandemic. DESIGN: Three repeated cross-sectional surveys over a 2-year period. Clients' free-text responses to open-ended questions were analyzed using a directed content analysis approach. SETTING: Forty-one counties in California. PARTICIPANTS: Current CalWORKs HVP clients and those who left the program in the 6 months prior to each survey. MAIN OUTCOME MEASURES: Clients' experience of the CalWORKs HVP. RESULTS: Five main themes emerged: (1) benefits received from the program; (2) life challenges; (3) COVID-19-related or other program changes; (4) client dissatisfaction and suggestions for improvement; and (5) appreciation for the program. Clients valued the practical, financial, parenting, and interpersonal support provided to themselves and their children. Almost three-quarters commented on life challenges experienced during the program. Significant programmatic changes related to COVID-19 pandemic public health safety and organizational constraints impacted clients both positively and negatively. Very few clients experienced overt dissatisfaction with the program. Many clients expressed appreciation for the program, particularly the individualized and relational support offered by a consistent home visitor. CONCLUSIONS: The findings provide insights into the benefits and challenges experienced by clients receiving evidence-based home visiting services. The findings highlight the ongoing life challenges faced by clients who experience poverty, and how those challenges were exacerbated by a global pandemic. The CalWORKs HVP may buffer the substantial personal stresses clients experience related to parenting in the context of poverty and major public health challenges.

Symptoms and associated impact in pre- and postmenopausal women with sexual arousal disorder: a concept elicitation study.

BACKGROUND: Approximately 26% of adult women in the United States suffer from female sexual arousal disorder (FSAD), yet little has been done to compare the experience of FSAD in pre- and postmenopausal women, which is critical to enhance the current understanding of FSAD and inform the development and assessment of treatment options for these patient populations. AIM: To explore the experience of condition-associated symptoms and the relative importance of FSAD symptoms, including their severity, bother, and impact, on participants' health-related quality of life (HRQoL) in pre- and postmenopausal women with FSAD. METHODS: In-depth, qualitative, semistructured concept elicitation interviews were conducted with premenopausal (n = 23) and postmenopausal (n = 13) women who were clinically diagnosed with FSAD by a trained sexual medicine clinician. All interviews were audio recorded and transcribed verbatim by a professional transcription company. Thematic analysis was performed with the assistance of NVivo qualitative analysis software. OUTCOMES: Outcomes included qualitative interview data about FSAD symptoms and HRQoL, as well as a comparison between pre- and postmenopausal populations. RESULTS: The most frequently reported symptom in both cohorts was "inability or difficulty with orgasm" (premenopausal, n = 21; postmenopausal, n = 13). The symptom that premenopausal women most desired to have treated was lubrication, and for postmenopausal women, it was a lack of lubrication or wetness and loss of feeling/sensation. In total, 21 of 23 premenopausal women and all 13 postmenopausal women reported a lack of feeling or sensation in the genitals. The most frequently reported HRQoL impact in both groups was decreased confidence. CLINICAL IMPLICATIONS: Results from this study suggest that the manifestation and experience of FSAD are similar in pre- and postmenopausal women and that the unmet need for an FSAD treatment in the postmenopausal population is just as great as that of the premenopausal population. STRENGTHS AND LIMITATIONS: This study involved in-depth qualitative interviews with a relatively small group of women (N = 36) recruited from only 5 study sites across the United States. CONCLUSION: The analysis of qualitative data from the concept elicitation interviews revealed a substantial physical and emotional burden of FSAD, underscoring the need for Food and Drug Administration-approved treatment options for pre- and postmenopausal women with FSAD.

Preliminary Efficacy of Topical Sildenafil Cream for the Treatment of Female Sexual Arousal Disorder: A Randomized Controlled Trial.

OBJECTIVE: To assess the efficacy of topical sildenafil cream, 3.6% among healthy premenopausal women with female sexual arousal disorder. METHODS: We conducted a phase 2b, exploratory, randomized, placebo-controlled, double-blind study of sildenafil cream. Coprimary efficacy endpoints were the change from baseline to week 12 in the Arousal Sensation domain of the SFQ28 (Sexual Function Questionnaire) and question 14 of the FSDS-DAO (Female Sexual Distress Scale-Desire, Arousal, Orgasm). RESULTS: Two hundred women with female sexual arousal disorder were randomized to sildenafil cream (n=101) or placebo cream (n=99). A total of 174 participants completed the study (sildenafil 90, placebo 84). Among the intention-to-treat (ITT) population, which included women with only female sexual arousal disorder and those with female sexual arousal disorder with concomitant sexual dysfunction diagnoses or genital pain, although the sildenafil cream group demonstrated greater improvement in the SFQ28 Arousal Sensation domain scores, there were no statistically significant differences between sildenafil and placebo cream users in the coprimary and secondary efficacy endpoints. An exploratory post hoc subset of the ITT population with an enrollment diagnosis of female sexual arousal disorder with or without concomitant decreased desire randomized to sildenafil cream reported significant increases in their SFQ28 Arousal Sensation domain score (least squares mean 2.03 [SE 0.62]) compared with placebo cream (least squares mean 0.08 [SE 0.71], P =.04). This subset achieved a larger mean improvement in the SFQ28 Desire and Orgasm domain scores. This subset population also had significantly reduced sexual distress and interpersonal difficulties with sildenafil cream use as measured by FSDS-DAO questions 3, 5, and 10 (all P ≤.04). CONCLUSION: Topical sildenafil cream improved outcomes among women with female sexual arousal disorder, most significantly in those who did not have concomitant orgasmic dysfunction. In particular, in an exploratory analysis of a subset of women with female sexual arousal disorder with or without concomitant decreased desire, topical sildenafil cream increased sexual arousal sensation, desire, and orgasm and reduced sexual distress.

Comparison of Biaxial Biomechanical Properties of Post-menopausal Human Prolapsed and Non-prolapsed Uterosacral Ligament.

Uterosacral ligaments (USLs) provide structural support to the female pelvic floor, and a loss of USL structural integrity or biomechanical function may induce pelvic organ prolapse (POP). Alterations in extracellular matrix composition and organization dictate USL mechanical function. Changes in USL microstructure and corresponding mechanical properties, however, are not fully understood, nor is it understood how microstructure and mechanics change with onset and progression of POP. This is due, in part, as USL properties are primarily characterized along a single direction (uniaxial test), whereas the USL is loaded in multiple directions simultaneously within the body. Biaxial testing permits the acquisition of biomechanical data from two axes simultaneously, and thus simulates a more physiologic assessment compared to the traditional uniaxial testing. Therefore, the objective of this study was to quantify the biaxial biomechanical properties and histological composition of the USL in post-menopausal women with and without POP at various stages. Potential correlations between tissue microstructural composition and mechanical function were also examined. Tangential modulus was lower and peak stretch higher in POP III/IV compared to non-POP and POP I/II in the main in vivo loading direction; however, no significant differences in mechanical properties were observed in the perpendicular loading direction. Collagen content positively correlated to tangential modulus in the main in vivo loading direction (r = 0.5, p = 0.02) and negatively correlated with the peak stretch in both the main in vivo (r = -0.5, p = 0.02) and perpendicular loading directions (r = -0.3, p = 0.05). However, no statistically significant differences in USL composition were observed, which may be due to the small sample size and high variability of small sections of human tissues. These results provide first step towards understanding what microstructural and mechanical changes may occur in the USL with POP onset and progression. Such information may provide important future insights into the development of new surgical reconstruction techniques and graft materials for POP treatment.
