Purpose This study assessed the benefit of adding behavioural modification to darifenacin treatment for overactive bladder (OAB). Materials and methods The ABLE trial was a randomised, open-label, parallel-group, multicentre study of 12 weeks of darifenacin treatment [with voluntary up-titration from 7.5 mg once daily (qd) to 15 mg qd at week 2] alone or in combination with a Behavioural Modification Programme (BMP) for men and women with dry or wet OAB. Efficacy was assessed as the change in the number (per day) of micturitions (primary variable), urge urinary incontinence (UUI) episodes, urgency episodes, pads used and nocturnal voids. Health-related quality of life (HRQoL) was also evaluated. Tolerability and safety assessments included adverse events and the number of discontinuations. Results Of 592 patients screened, 395 were randomised, 190 to darifenacin alone and 205 to darifenacin + BMP. At baseline, the majority of subjects were dry (mean 2.8 and three UUI episodes per day in the darifenacin and darifenacin + BMP groups respectively). At study end, darifenacin alone and darifenacin + BMP both produced significant reductions from baseline in median numbers of micturitions, UUI episodes, urgency episodes and nocturnal voids (all p < 0.05), but not in the number of pads used. HRQoL also improved. There were no significant differences between treatment groups in efficacy or HRQoL variables. Conclusions Darifenacin treatment provides a degree of normalisation of micturition variables and improvement in HRQoL that cannot be further enhanced by behavioural therapy of the type used in this study. Whether behavioural modification would add benefit over darifenacin treatment in patients with more pronounced incontinence problems remains to be determined.

Background: Testosterone replacement therapies may increase blood pressure (BP) with chronic use but the mechanism is not clear. TLANDO™ is a new oral testosterone undecanoate (TU) under development for the treatment of male hypogonadism. Methods: We studied the effects of the TU at 225 mg twice daily on ambulatory BP (ABP) and heart rate, in 138 men with hypogonadism (mean age, 54 years, 79% white, 48% with hypertension). Ambulatory BP and heart rate and hematologic assessments were obtained at baseline and following 4-months of therapy. Results: Changes from baseline in ambulatory 24-hour, awake, and sleep systolic BP (SBP) of 3.8 ( P < 0.001), 5.2 ( P < 0.001), and 4.3 mmHg ( P = 0.004) were observed post-treatment, respectively. Lesser changes in the diastolic BP (DBP) were observed (1.2 ( P = 0.009), 1.7 ( P = 0.004), and 1.7 mmHg ( P = 0.011) for 24-hour, awake, and sleep, respectively). Hematocrit and hemoglobin were increased by 3.2% and 0.9 g/dL ( P < 0.001), respectively. In those men in the top quartile of changes in hematocrit (range of 6% to 14%), the largest increases in ambulatory SBP (mean, 8.3 mmHg) were observed, whereas the changes in ambulatory SBP in the lower 3 quartiles were smaller (mean, 1.9, 3.3, and 2.1 mmHg in 1st, 2nd and 3 rd quartiles, respectively). Conclusion: These data demonstrate that small increases in ABP occurred following 4 months of the oral TU. For those men whose hematocrit rose by >6%, BP increases were of greater clinical relevance. Hence, hematocrit may aid in predicting the development of BP increases on testosterone therapy. ClinicalTrials.gov identifier: NCT 03868059.
