Abstract
Velufenacin (DA-8010) is a new muscarinic receptor antagonist under development for the treatment of overactive bladder. This study aimed to evaluate the effect of food on the pharmacokinetics (PK) and safety of velufenacin in healthy subjects. A randomized, open-label, single-dose, 4-sequence, 4-treatment, 4-period crossover study was conducted. Subjects received a single oral dose of velufenacin 2.5 or 5 mg in a fasted or fed (high-fat meal) state in each period with a 7-day washout. PK parameters including maximum plasma concentration (Cmax ) and area under the concentration-time curve from time 0 to the last measurable point were compared between the fed and fasted states. Twenty-seven subjects completed the study. The mean area under the concentration-time curve from time 0 to the last measurable point of the velufenacin 2.5 and 5 mg doses under the fed condition showed a 1.5- and 1.3-fold increase, respectively, compared to the fasted condition. The corresponding values for Cmax were a 2.3- and 2.0-fold increase, respectively. The time to reach Cmax was comparable regardless of the dose or food intake, showing median values of 4.5-5.0 hours. These results suggest a modest increase of velufenacin absorption by food intake. Velufenacin was generally safe and well tolerated at the 2.5 and 5 mg doses regardless of food.

Sci Rep 2023; 13:18395.

Abstract
Overactive bladder (OAB) is a common, long-term symptom complex with a high prevalence in women worldwide. OAB has caused a social burden, and effective treatments are urgently needed. However, the pathogenesis of OAB has yet to be elucidated. Model rats underwent bladder outlet obstruction surgery. In the 2nd, 3rd, and 4th weeks after surgery, metabolic cages were used to detect the 12 h urine volume of rats in the sham and model groups. The urodynamic parameters bladder leak point pressure (BPLL), maximum voiding pressure (MVP), residual volume (RV), maximum bladder capacity (MBC), bladder compliance (BC), voided efficiency (VE), and non-voiding contractions (NVCs) were also detected. Moreover, the contractile responses of isolated detrusor muscles to electrical and carbachol stimulation were examined at the abovementioned time points. At the 4th week after surgery, the bladders of both groups were obtained for hematoxylin-eosin (H&E) and Masson's trichrome staining. Real-time qPCR and Western blot were performed to quantify the expression of choline acetyltransferase (ChAT) and solute carrier family 17 member 9 (SLC17A9). At week 4, compared with the sham group, the 12 h urine volume of PBOO group increased significantly. The BLPP, MVP, VE, MBC, and NVCs increased significantly, and the VE was significantly reduced in 4-week PBOO group. The contractile responses of isolated detrusor muscles to electrical and carbachol stimulation significantly increased in 4-week PBOO group. In the 4-week PBOO group, the bladder wall and the ratio of bladder muscle to collagen within the bladder smooth muscle layer wall were significantly higher than those in the sham group. ChAT and SLC17A9 mRNA and protein expression in the OAB model rats significantly increased. At 4 weeks after PBOO, the OAB model was successfully established. The gene and protein expression levels of ChAT and SLC17A9 increased in the bladder of the OAB model, suggesting that OAB may be related to increased excitatory purinergic and cholinergic expression.

Pharmacol Res Perspect 2023; 11:e01040. [PMID: 36734627 PMCID: PMC9897050 DOI: 10.1002/prp2.1040] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 11/24/2022] [Accepted: 12/02/2022] [Indexed: 02/04/2023] Open
Abstract
This study assessed the safety, tolerability, and pharmacokinetics of single and multiple oral doses of DA-8010, a muscarinic M3 receptor antagonist, in healthy subjects. This was a randomized, double-blind, placebo-controlled, ascending single (Part A: 1, 2.5, 5, 20, and 40 mg QD fasted and 10 mg QD fasted and fed) and multiple doses (Part B: 5, 10, and 20 mg QD from Days 1 to 7 fasted), sequential-group study. Safety data were analyzed descriptively, time to maximum plasma concentration (tmax ) nonparametrically, and pharmacokinetic parameters using power and mixed models and ANOVA. Of 109 subjects randomized (Part A = 69 and Part B = 40; each part consisted a female group), 31 (44.9%) in Part A and 29 (72.5%) in Part B experienced treatment-emergent adverse events (TEAEs) in a dose-related manner. Common drug-related TEAEs in Part A and B were dizziness (8.7% and 15.0%), headache (5.8% and 12.5%) and blurred vision (8.7% and 20%). One male (20 mg) and one female (10 mg) from Part B discontinued the study due to a confusional state, and nausea and vomiting. Irrespective of sex, DA-8010 was steadily absorbed following single and multiple doses in the fasted state with increased systemic exposure in a dose-proportional manner with maximum plasma concentration occurring at a median tmax between 4.0 and 6.0 h. A high-fat meal increased systemic exposure. DA-8010 was safe, well tolerated, and well absorbed at lower doses and moderately tolerated at higher doses without any notable effects of food and sex.

Efficacy and Safety of DA-8010, a Novel M3 Antagonist, in Patients With Overactive Bladder: A Randomized, Double-Blind Phase 2 Study. Int Neurourol J 2022; 26:119-128. [PMID: 35793990 PMCID: PMC9260321 DOI: 10.5213/inj.2142382.191] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2021] [Accepted: 01/09/2022] [Indexed: 11/08/2022] Open
Abstract
Purpose: DA-8010 is a novel muscarinic M3 receptor antagonist with significant selectivity for bladder over salivary gland in preclinical studies. We evaluated the clinical efficacy and safety of DA-8010 in overactive bladder (OAB) patients.Methods: This phase 2, randomized, double-blind, parallel-group, active reference- and placebo-controlled trial was conducted at 12 centers in South Korea (NCT03566134). Patients aged ≥19 years with OAB symptoms for ≥3 months were enrolled. Three hundred six patients (30.07% male) were randomized to 12 weeks of treatment among 4 groups; 2 experimental groups (DA-8010 2.5 or 5 mg), an active reference group (solifenacin 5 mg), and a placebo group. The change from the baseline of (=∆) 24-hour frequency at 12 weeks (primary endpoint), episodes of urgency, overall/urgency urinary incontinence, average/ maximum voided volume, nocturia, and patients’ subjective responses were analyzed.Results: In the full analysis set, the mean (standard deviation) [median] values for ∆ 24-hour frequency at 12 weeks were -1.01 (2.44) [-1.33] for placebo, -1.22 (2.05) [-1.33] for DA-8010 2.5 mg, and -1.67 (2.25) [-1.67] for DA-8010 5 mg; DA-8010 5 mg showed a significant decrease compared with placebo (P=0.0413). At 4 and 8 weeks, both DA-8010 2.5 mg (P=0.0391 at 4 weeks, P=0.0335 at 8 weeks) and DA-8010 5 mg (P=0.0001 at 4 weeks, P=0.0210 at 8 weeks) showed significant decrease in ∆ 24-hour frequency compared with placebo. DA-8010 5 mg achieved a significant decrease in ∆ number of urgency episodes, compared with placebo at 4 (P=0.0278) and 8 (P=0.0092) weeks. Adverse drug reactions (ADRs) were observed in 3.95% of placebo, 6.67% of DA-8010 2.5 mg, 18.42% of DA-8010 5 mg, and 17.33% of solifenacin 5 mg groups. No serious ADRs were observed in any patient.Conclusions: Both DA-8010 2.5 mg and 5 mg showed therapeutic efficacy for OAB without serious ADRs. Therefore, both dosages of DA-8010 can advance to a subsequent large-scale phase 3 trial.

Abstract
Pharmacological management of urinary incontinence (UI) is currently based on antimuscarinic and beta-3-agonist drugs. Botulinum toxin A detrusor injections represent an effective but more invasive alternative. This review covers the latest developments of the currently available drugs and the emerging compounds for the treatment of UI. Evidence shows that new antimuscarinics and beta-3-agonists with improved safety profiles may offer unique options to patients intolerant to currently available drugs. Combination therapy proved to be a non-invasive alternative for patients refractory to first-line monotherapy. Exciting advances are ongoing in the research to improve the efficacy/tolerability profile of botulinum toxin, through innovative routes of administration. Several new agents emerged from preclinical studies, some of which have now entered the clinical phase of development and could represent, in the coming years, a new way for the treatment of UI. Recent evidence on the existence of different overactive bladder phenotypes could be the key to tailored treatment. Rather than discovering new molecules, reaching the ability to identify the right drug for the right patient could be the real gamechanger of the future.
