    ABSTRACT: To evaluate, posthoc, the relationship between serum total testosterone and response to therapy in a study of tadalafil once daily for erectile dysfunction (ED). Men were aged ≥18 years, with ≥3-month history of ED and partial prior response to on-demand (PRN) phosphodiesterase type 5 inhibitor (PDE5I) therapy. A 4-week maximum-dose PRN PDE5I run-in was followed by a 4-week nondrug washout period, then randomization to tadalafil 2.5 mg titrated to 5 mg or tadalafil 5 mg (pooled for analyses) or placebo once daily for 12 weeks. Analyses compared endpoint efficacy results between low- (<300 ng/dL) vs normal-testosterone (≥300 ng/dL) level subgroups. Improvements for tadalafil vs placebo were significant for the International Index of Erectile Function (IIEF) Erectile Function domain, Intercourse Satisfaction domain, Overall Satisfaction domain, and Question 15 (confidence in the ability to get and keep an erection; all P <.001), and for the Sexual Encounter Profile Questions 1-5 (all P ≤.011). Analysis of covariance modeling identified significant treatment-by-subgroup interactions for the IIEF-Overall Satisfaction domain and erection confidence question and Sexual Encounter Profile Question 3. Comparing between tadalafil-treated testosterone subgroups, the IIEF-Erectile Function domain scores improved significantly more in men with normal vs low testosterone (P = .022); no other significant differences were identified for either placebo or tadalafil. No significant differences in pre-existing conditions were observed between tadalafil and placebo within the normal- and low-testosterone subgroups. In men with partial response to a PRN PDE5I, tadalafil 5 mg once daily significantly improved ED and sexual function vs placebo irrespective of testosterone levels.

    ABSTRACT: To assess the efficacy and safety of oxybutynin transdermal gel 3% (OTG3%), with propylene glycol for enhanced skin permeation, in patients with urinary incontinence (UI). In this phase 3 study, 626 patients ≥18 years old with urgency and/or mixed UI symptoms and predominantly urgency UI for ≥3 months were randomized 1:1:1 to receive 12 weeks of OTG3% 84 mg, OTG3% 56 mg, or placebo gel applied once daily to abdomen, inner/upper thigh, or upper arm/shoulder. Primary efficacy endpoint was change from baseline to Week 12 in weekly UI episodes recorded in 3-day bladder diaries. Results were compared using analysis of covariance. Adverse events (AEs) were monitored. Efficacy was assessed in 601 (intent-to-treat) and safety in 626 patients. At 12 weeks, OTG3% 84 mg/day achieved significantly greater improvement versus placebo in weekly UI episodes (mean change from baseline: -20.4 vs. -18.1; P < 0.05), daily urinary frequency (-2.6 vs. -1.9; P = 0.001), and urinary void volume (32.7 vs. 9.8; P < 0.0001(b) ). Dry mouth, the most common treatment-related AE, occurred more often with OTG3% 84 mg/day (26/214 [12.1%]) vs. placebo (10/202 [5.0%]) (P = 0.028); 4 OTG3% patients withdrew because of dry mouth. Application site erythema occurred more often with OTG3% 84 mg/day (8/214 [3.7%]) versus placebo (2/202 [1.0%]) (P = NS); 12 OTG patients withdrew because of skin irritation. No serious treatment-related AEs occurred. OTG3% 84 mg/day was well tolerated and effective in improving urge incontinence or mixed UI symptoms with a predominance of UI in adults with overactive bladder. Neurourol.

    ABSTRACT: To assess the efficacy and safety of tadalafil, a phosphodiesterase 5 (PDE5) inhibitor efficacious for erectile dysfunction and lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH), in population subgroups, using pooled data from 4 international, randomized, placebo-controlled studies in men with LUTS/BPH. The safety database included 1500 men randomized to tadalafil 5 mg once daily or placebo for 12 weeks. Changes in total International Prostate Symptom Score (IPSS), IPSS-quality of life index, and BPH impact index were examined overall, and changes in IPSS or adverse events (AEs) were examined across subgroups of interest. Treatment-group differences were assessed using analysis of covariance. Results of pooled data confirmed that tadalafil (N = 752) resulted in significant improvements from baseline vs placebo (N = 746) in IPSS (mean difference -2.3; P <.001), and also in BPH impact index and IPSS-quality of life index (both P <.001). Subgroup analyses demonstrated that IPSS improvements were significant regardless of baseline LUTS severity (IPSS <20/≥20), age (≤65/>65 years), recent previous use of α-blockers or PDE5 inhibitors, total testosterone level (<300/≥300 ng/dL), or prostate-specific antigen predicted prostate volume (≤40/>40 mL). Rates of treatment emergent AEs were comparable between subgroups of baseline age (≤65/>65 years), previous PDE5 inhibitor use, and the presence or absence of pre-existing diabetes, hypertension, or cardiovascular disease (including hypertension), but somewhat higher for recent previous α-blocker use. In these pooled data analyses, tadalafil 5 mg improved LUTS/BPH across subgroups of age, LUTS severity, testosterone levels, and prostate volume. Rates of AEs were similar across the subgroups assessed.

    ABSTRACT: An optimal outcome of an erectile dysfunction (ED) treatment is to enable a return to normal erectile function (as defined by an International Index of Erectile Function-Erectile Function [IIEF-EF] domain score ≥26). As-needed (PRN) phosphodiesterase type 5 (PDE5) inhibitor treatment does not always result in a return-to-normal erectile function. The combined studies evaluated whether treatment with tadalafil once daily would allow men to return to normal erectile function who had less than normal IIEF-EF domain scores while using a maximum dose of a PRN PDE5 inhibitor treatment. Men were ≥18 years of age, sexually active, reported a ≥3-month history of ED, and had been taking the maximum dose of sildenafil citrate, vardenafil, or tadalafil PRN. Randomization to once-daily therapy with tadalafil 2.5 mg to 5 mg (N = 207), tadalafil 5 mg (N = 207), or placebo (N = 209) for 12 weeks followed a 4-week maximum dose PRN PDE5 treatment and 4-week nondrug lead periods. Two identical double-blind, randomized, placebo-controlled studies were conducted; combined results are reported. The main outcome measure was the percentage of subjects with a return-to-normal erectile function (IIEF-EF domain score ≥ 26) when treated with tadalafil once daily compared with placebo. In subjects not achieving normal erectile function with the maximum dose of a PRN PDE5 inhibitor, a higher percentage of subjects treated with tadalafil had an IIEF-EF domain score ≥26 at end point (tadalafil 2.5- to 5-mg group [39%]; tadalafil 5-mg group [40%]) compared with the placebo group (12.1%; P < 0.001). Tadalafil was generally well tolerated and adverse events observed were consistent with previous reports of tadalafil once daily. Treatment with tadalafil once daily significantly improved erectile function in men with mild to mild-moderate impairments in erectile function following PRN PDE5 inhibitor treatment.

    ABSTRACT: The Decreased Sexual Desire Screener is a brief diagnostic instrument for generalized acquired Hypoactive Sexual Desire Disorder in women. During the screening visit of 2 clinical trials, the authors assessed sensitivity of the Decreased Sexual Desire Screener in premenopausal women presenting with decreased sexual desire. The authors compared diagnoses of generalized acquired Hypoactive Sexual Desire Disorder made by clinicians who were not trained or specialized in the diagnosis of female sexual dysfunction using the Decreased Sexual Desire Screener with diagnoses made by expert clinicians after an extensive diagnostic interview. The sensitivity of the Decreased Sexual Desire Screener was 0.946 in a North American trial and 0.960 in a European trial.

    ABSTRACT: Flibanserin is a 5-HT(1A) agonist/5-HT(2A) antagonist that has been shown to increase sexual desire and reduce distress in premenopausal women with Hypoactive Sexual Desire Disorder (HSDD). To assess the efficacy and safety of flibanserin over 24 weeks of double-blind treatment vs. placebo in premenopausal women with HSDD who showed a predefined response after 24 weeks of open-label treatment with flibanserin. Women (N = 738) were treated with open-label, flexible-dose flibanserin (50 mg or 100 mg/day) for 24 weeks. At week 24, women who showed a predefined response, measured using an eDiary, were randomized to 24 weeks of continued flibanserin therapy at optimized dosage (N = 163) or placebo (N = 170). The criteria for entering the double-blind phase were an increase from baseline to weeks 21-24 of ≥2 satisfying sexual events (SSE) and/or ≥4 "desire days." A "desire day" was one in which a woman reported more than "no" desire. Coprimary endpoints were change from randomization to study end in SSE and desire score. Secondary measures included change in Female Sexual Function Index (FSFI) total and desire domain scores and Female Sexual Distress Scale-Revised (FSDS-R) total and Item 13 scores. During the open-label period, mean SSE and desire score approximately doubled, and FSFI, FSDS-R total, and Item 13 scores improved. At the end of the double-blind period, flibanserin was superior to placebo in change from randomization in SSE, desire score, FSFI desire domain and total scores, and FSDS-R total and Item 13 scores (P < 0.05, for all). Flibanserin was well tolerated, and withdrawal reactions were not observed. At the end of the 24-week randomized withdrawal phase of a 48-week trial in premenopausal women with HSDD, flibanserin was superior to placebo on measures of SSE, sexual desire, overall sexual function, and sexual distress. Flibanserin was well tolerated, and no withdrawal reactions were observed following discontinuation.

    ABSTRACT: To assess changes in overactive bladder (OAB) symptoms and patient-reported outcomes in a post hoc analysis in which subjects from a 12-week, open-label, flexible-dose fesoterodine study were stratified according to whether they opted for dose escalation. Subjects with OAB (eight or more micturitions and three or more urgency episodes per 24 h) who reported dissatisfaction with tolterodine within 2 years of screening received fesoterodine 4 mg once daily for 4 weeks, with an optional dose increase to 8 mg after week 4 based on discussion of efficacy and tolerability between the subject and investigator. Subjects completed 5-day diaries, the Patient Perception of Bladder Condition (PPBC) and Urgency Perception Scale (UPS) at baseline and weeks 4 and 12, and the Overactive Bladder Questionnaire (OAB-q) at baseline and week 12. Subjects rated treatment satisfaction at week 12. Dose escalation to 8 mg at week 4 was chosen by 255 (50%) of 513 subjects. At baseline, subjects who opted for dose escalation at week 4 (escalators) had significantly higher means for all diary variables except urgency urinary incontinence (UUI) episodes, significantly greater OAB-q Symptom Bother scores and significantly lower OAB-q health-related quality of life (HRQL) scores (all P < 0.05) compared to subjects who did not opt for dose escalation (non-escalators). There was no significant difference in the percentage of escalators (51%) and non-escalators (48%) who reported at least one UUI episode on baseline diary. At week 4 (before the decision to escalate was made), all outcomes were significantly improved vs baseline among both groups (all P < 0.0001), although non-escalators had significantly greater improvements in all diary variables and in PPBC and UPS scores than escalators (all P < 0.05), and the 5-day diary-dry rate (i.e. the percentage of subjects with at least one UUI episode on baseline diary and no UUI episodes on week 4 diary) was significantly higher (P = 0.0016) among non-escalators (62%) than among escalators (42%). At week 12, all outcomes were again significantly improved vs baseline among both groups (all P < 0.0001). There were no significant differences between non-escalators and escalators in week 12 improvements for most diary variables, UPS scores, OAB-q Symptom Bother scores, the diary-dry rate (68% vs 60%) or the percentage of subjects who reported treatment satisfaction (82% vs 78%). However, escalators still had significantly greater improvements from baseline in urgency episodes, PPBC scores and OAB-q total HRQL and Coping domains (P < 0.05). Adverse event rates were similar between non-escalators and escalators. Dry mouth was the most frequently reported adverse event; most cases were mild. Flexible-dose fesoterodine significantly improved OAB symptoms and patient-reported outcomes in subjects who chose to remain on the initial 4-mg dose, as well as in the 50% of subjects who escalated to the 8-mg dose after 4 weeks. Non-escalators had significantly fewer OAB symptoms at baseline and significantly greater improvements than escalators before dose escalation. Escalators showed increased symptom relief after dose escalation; improvements in most outcomes were similar among non-escalators and escalators by week 12. Flexible-dose fesoterodine was well tolerated, with similar adverse-event profiles observed in the escalator and non-escalator groups. These results may help clinicians to identify patients more likely to require fesoterodine 8 mg to achieve maximum relief of OAB symptoms and thus facilitate dose escalation in these patients.

    ABSTRACT: • To evaluate the 1-year safety of 5 mg of tadalafil once daily in men with lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH-LUTS); efficacy measures were included to evaluate the maintenance of efficacy after an additional year of treatment. • In total, 427 men who completed a 12-week, placebo-controlled, dose- finding study assessing once-daily tadalafil (2.5, 5, 10 or 20 mg) or placebo elected to continue into the open-label extension period. Safety and efficacy parameters were assessed after 1 month and every 3 months. • In total, 299 patients (69.9%) completed the 1-year, open-label extension period. Treatment-emergent adverse events (TEAEs) were reported by 57.6% of patients, with most TEAEs being mild (44%) or moderate (45%) in severity; the most common TEAEs (≥ 2%) were dyspepsia, gastro-oesophageal reflux disease, back pain, headache, sinusitis, hypertension and cough. Twenty-two patients (5.2%) discontinued as a result of AEs. During the open-label extension period, mean prostate-specific antigen increased from 1.6 ± 1.3 ng/mL to 1.8 ± 1.4 ng/mL. • Mean post-void residual volume was 61.1 ± 60.4 mL at study entry and 42.2 ± 64.1 mL after the open-label extension period. Changes in the total International Prostate Symptom Score (IPSS), IPSS irritative and obstructive subscores, IPSS health-related quality of life and BPH Impact Index were maintained after 1 year. In sexually-active patients with erectile dysfunction, improvements in the International Index of Erectile Function-Erectile Function domain were maintained after 1 year. • In men with BPH-LUTS, 5 mg of tadalafil once daily during 1 year of treatment was well tolerated and efficacy changes were maintained.

    ABSTRACT: We evaluated the efficacy onset and safety of tadalafil 2.5 and 5 mg once daily for 14 days compared with placebo in men with erectile dysfunction. In this randomized, double-blind, placebo controlled, parallel group study we randomized 372 men after a 4-week run-in period to receive placebo, or tadalafil 2.5 or 5 mg once daily for 14 days, followed by a 14-day open label extension period of tadalafil 5 mg once daily. Primary analysis focused on the cumulative percent of men with a successful intercourse attempt during the first 4 days of treatment. On secondary analysis we evaluated the percent of successful attempts during the study. The Sexual Encounter Profile diary question 3 was used to assess efficacy. Safety was assessed by monitoring adverse events and vital signs. Significantly more men in the tadalafil 5 mg group achieved successful intercourse, as indicated by a yes response to diary question 3, than those on placebo by day 2 (48.6% vs 36.6%, p < 0.025). The tadalafil 2.5 mg group did not separate from the placebo group on primary analysis. Secondary analysis showed that men on tadalafil 2.5 mg achieved a significantly higher percent of successful intercourse attempts than those on placebo by day 3 (35.5% vs 27.2%, p < 0.025). All groups further improved during the open label extension period. Tadalafil was well tolerated. This prospective trial shows the onset of efficacy of tadalafil 2.5 and 5 mg once daily within a few days of initiating therapy.

    ABSTRACT: The prescribing information for sildenafil citrate (VIAGRA, Pfizer, New York, NY, USA) recommends flexible dosing (50 mg initially, adjusted to 100 or 25 mg based on effectiveness and tolerability) in most men with erectile dysfunction (ED). In many men, however, 100 mg may be the most appropriate initial dose because it would reduce the need for titration and could prevent discouragement and treatment abandonment should 50 mg be insufficient. Results of two previously published double-blind, placebo-controlled sildenafil trials of similar design except for a fixed-dose vs flexible-dose regimen were analyzed. Relative to the flexible-dose, approximately one-third more men were satisfied with an initial and fixed dose of 100 mg. In addition, tolerability was similar, and improvements from baseline in outcomes on validated, ED-specific, patient-reported questionnaires were either similar (erectile function and the percentage of completely hard and fully rigid erections) or greater (emotional well-being and the overall sexual experience). The similarity in outcomes is not surprising given that almost 90% of the men in the flexible-dose trial titrated to 100 mg after 2 weeks. These data suggest prescription of an initial dose of 100 mg for men with ED, except in those for whom it is inappropriate.

    ABSTRACT: In the few studies to evaluate antimuscarinics for overactive bladder (OAB) in men, safety has been the primary focus. In OAB efficacy trials, subject populations have been predominantly female and patient-reported outcomes (PROs) have been assessed only recently. We present a post hoc analysis of PRO-based findings from the subset of men (without presumed bladder outlet obstruction [BOO]) from two large, independent, open-label trials of solifenacin. Subjects with OAB for > or =3 months received flexibly dosed solifenacin for 12 weeks. At baseline and 4-week intervals, subjects completed the Patient Perception of Bladder Condition (PPBC) and Overactive Bladder Questionnaire (OAB-q). In one study, subjects also completed 3-day bladder diaries. At baseline, mean PPBC scores were similar in both studies and indicative of moderate-to-severe problems. After 12 weeks of solifenacin, mean PPBC scores improved significantly (p < 0.0001); values were suggestive of minor-to-moderate problems. Mean scores on the OAB-q were also significantly improved after solifenacin (p values < or =0.001). In men without presumed BOO, solifenacin significantly improved PRO measures of symptom bother, health-related quality of life, and overall perception of bladder problems. Results from these two studies support the use of solifenacin as a well-tolerated and efficacious treatment option for providing symptom relief in men with OAB without BOO.

    ABSTRACT: To evaluate the efficacy and tolerability of flexible-dose fesoterodine in subjects with overactive bladder (OAB) who were dissatisfied with previous tolterodine treatment. This was a 12-week, open-label, flexible-dose study of adults with OAB (> or = 8 micturitions and > or = 3 urgency episodes per 24 h) who had been treated with tolterodine (immediate- or extended-release) for OAB within 2 years of screening and reported dissatisfaction with tolterodine treatment. Subjects received fesoterodine 4 mg once daily for 4 weeks; thereafter, daily dosage was maintained at 4 mg or increased to 8 mg based on the subject's and physician's subjective assessment of efficacy and tolerability. Subjects completed 5-day diaries, the Patient Perception of Bladder Condition (PPBC) and the Overactive Bladder Questionnaire (OAB-q) at baseline and week 12 and rated treatment satisfaction at week 12 using the Treatment Satisfaction Question (TSQ). Safety and tolerability were assessed. Among 516 subjects treated, approximately 50% opted for dose escalation to 8 mg at week 4. Significant improvements from baseline to week 12 were observed in micturitions, urgency urinary incontinence episodes, micturition-related urgency episodes and severe micturition-related urgency episodes per 24 h (all p < 0.0001). Approximately 80% of subjects who responded to the TSQ at week 12 reported satisfaction with treatment; 38% reported being very satisfied. Using the PPBC, 83% of subjects reported improvement at week 12 with 59% reporting improvement > or = 2 points. Significant improvements from baseline (p < 0.0001) exceeding the minimally important difference (10 points) were observed in OAB-q Symptom Bother and Health-Related Quality of Life (HRQL) scales and all four HRQL domains. Dry mouth (23%) and constipation (5%) were the most common adverse events; no safety issues were identified. Flexible-dose fesoterodine significantly improved OAB symptoms, HRQL, and rates of treatment satisfaction and was well tolerated in subjects with OAB who were dissatisfied with prior tolterodine therapy.

    ABSTRACT: An accurate diagnosis of Hypoactive Sexual Desire Disorder (HSDD) currently relies on a time-consuming interview with an expert clinician. Limited access to such expertise means that many women with HSDD remain undiagnosed. The Decreased Sexual Desire Screener (DSDS) was developed to provide clinicians who are neither trained nor specialized in Female Sexual Dysfunction (FSD) with a brief diagnostic procedure for the diagnosis of generalized acquired HSDD in women. A prospective non-treatment multicenter study enrolled 263 women at 27 centers in North America in order to test the validity of the DSDS for diagnosing generalized acquired HSDD in women. Subjects completed the DSDS at the screening visit and their answers were reviewed with a clinician who was not an expert in FSD ("non-expert clinician"). Separately and while being unaware of the non-expert clinician's diagnosis, an expert clinician conducted a standard diagnostic interview. Diagnostic outcomes (generalized acquired HSDD or not) were compared. Primary endpoints included the sensitivity and specificity of the DSDS relative to the standard diagnostic interview. Subject and non-expert clinician debriefing were obtained via a written, structured interview. This ensured that a large sample could be tested under uniform conditions across multiple sites. Diagnostic assessment by DSDS and standard diagnostic interview were in agreement in 85.2% (224/263) of cases, with the sensitivity and specificity of the DSDS 83.6% and 87.8%, respectively. Debriefing showed that the five DSDS questions were well understood by 85.4% (76/89) of subjects included in the debriefing exercise, while non-expert clinicians considered the DSDS questions adequate to diagnose HSDD in 92.9% (235/253) of cases. The DSDS is a sensitive and specific brief diagnostic instrument for generalized acquired HSDD in women that is quick and easy to use.

    ABSTRACT: Erectile dysfunction is increasingly common with advancing age, yet sexual activity and intimacy are important to elderly men. To assess the efficacy and tolerability of tadalafil in men over the age of 65 years. In this multicenter open-label study, 188 men (mean age = 71.6 years) who were over age 65 and did not have diabetes mellitus or clinical depression received tadalafil 20 mg, taken on demand, for up to 12 weeks. Efficacy was assessed using the International Index of Erectile Function (IIEF) and Sexual Encounter Profile (SEP). Psychosocial outcomes were evaluated using the Psychological and Interpersonal Relationship Scale (PAIRS). Tadalafil treatment significantly improved all domains of the IIEF from baseline, including the erectile function (EF) domain (change = 8.8, end point = 21.6; P < 0.001). Mean per-patient percentage of "yes" responses to SEP questions concerning successful penetration (SEP2; change = 33.5%, end point = 73.5%; P < 0.001) and successful intercourse (SEP3; change = 39.6%, end point = 59.6%; P < 0.001) also improved significantly from baseline. Forty percent of the patients with baseline EF scores < 26 had normal EF (IIEF-EF domain scores > or = 26) at end point, and 81% reported improved erections in the Global Assessment Questionnaire. At least 56% of attempts at sexual intercourse were successfully completed (SEP3) at all time intervals up to 36 hours after tadalafil administration. The patients also experienced significant improvement in both the sexual self-confidence and spontaneity domains of the PAIRS. Tadalafil was well tolerated, with < 5% of the patients discontinuing because of adverse events. Tadalafil 20 mg was effective and well tolerated in elderly men with ED.

    ABSTRACT: In two randomized, double-blind, placebo-controlled trials of 100 mg sildenafil citrate, men (N=601) with mild to moderate erectile dysfunction (ED) attempted intercourse 8 h (range, 7-9 h) postdose. The baseline to end-of-treatment improvement in the sildenafil groups vs placebo was greater (P<0.001) for the per-patient proportion (PPP) of 'yes' responses to the Sexual Encounter Profile question 3 (SEP3: successful intercourse (primary outcome)) (odds ratio (OR)=3.2 (trial 1), 7.6 (trial 2) and 5.6 (pooled data)); PPP of erection hardness score 4 (EHS 4, completely hard and fully rigid) (OR=6.2 (trial 1) and 10.9 (trial 2)); scores on the International Index of Erectile Function; and other EHS and SEP outcomes. Two to three times as many men were satisfied with sildenafil vs placebo treatment (Erectile Dysfunction Inventory of Treatment Satisfaction Index >50). Thus, responsiveness to 100 mg sildenafil may persist for 8 h postdose in men with mild to moderate ED.
