RESUMO

BACKGROUND: Poor patient adherence with antiacne medications is a common clinical challenge. DMT310, a natural, topical product with a once-weekly application schedule, may alleviate this obstacle. OBJECTIVE: Evaluate the safety, tolerability, and efficacy of DMT310 in treating moderate-to-severe acne. METHODS: This 12-week, randomized, double-blind, placebo-controlled, multicenter clinical trial enrolled participants 12 years and older with moderate-to-severe acne. RESULTS: The intent-to-treat population included a total of 181 participants (DMT310, N = 91; placebo, N = 90). Participants who received DMT310 vs participants treated with placebo demonstrated a statistically significant greater reduction in the number of inflammatory and noninflammatory lesions at all time points: inflammatory lesion counts at week 12 (-15.64 vs -10.84, P < .001); noninflammatory lesion counts at week 12 (-18.26 vs -12.41, P < .001). DMT310-treated participants also had higher rates of Investigator's Global Assessment treatment success than participants in the placebo group at all time points: Investigator's Global Assessment at week 12 (44.40% vs 17.78%; P < .001). No serious treatment related adverse events occurred. CONCLUSIONS: DMT310 once-weekly topical treatment significantly reduced both inflammatory and noninflammatory lesions and yielded a greater proportion of Investigator's Global Assessment treatment success at all time points in participants with moderate-to-severe acne.

RESUMO

PURPOSE: Overactive bladder affects 12% to 17% of the general population and almost a third experience urinary incontinence, which may severely impact health related quality of life. Oral anticholinergics are the mainstay of pharmacological treatment but they are limited by inadequate efficacy or side effects, leading to a high discontinuation rate. We report the results of the first large (557 patients), phase 3, placebo controlled trial of onabotulinumtoxinA in patients with overactive bladder and urinary incontinence inadequately managed with anticholinergics. MATERIALS AND METHODS: Eligible patients with overactive bladder, 3 or more urgency urinary incontinence episodes in 3 days and 8 or more micturitions per day were randomized 1:1 to receive intradetrusor injection of onabotulinumtoxinA 100 U or placebo. Co-primary end points were the change from baseline in the number of urinary incontinence episodes per day and the proportion of patients with a positive response on the treatment benefit scale at posttreatment week 12. Secondary end points included other overactive bladder symptoms and health related quality of life. Adverse events were assessed. RESULTS: OnabotulinumtoxinA significantly decreased the daily frequency of urinary incontinence episodes vs placebo (-2.65 vs -0.87, p <0.001) and 22.9% vs 6.5% of patients became completely continent. A larger proportion of onabotulinumtoxinA than placebo treated patients reported a positive response on the treatment benefit scale (60.8% vs 29.2%, p <0.001). All other overactive bladder symptoms improved vs placebo (p ≤0.05). OnabotulinumtoxinA improved patient health related quality of life across multiple measures (p <0.001). Uncomplicated urinary tract infection was the most common adverse event. A 5.4% rate of urinary retention was observed. CONCLUSIONS: OnabotulinumtoxinA 100 U showed significant, clinically relevant improvement in all overactive bladder symptoms and health related quality of life in patients inadequately treated with anticholinergics and was well tolerated.

RESUMO

BACKGROUND: This phase III study was undertaken to evaluate the efficacy of an allogeneic whole-cell vaccine (Canvaxin™) plus bacillus Calmette-Guerin (BCG) after complete resection of stage IV melanoma. METHODS: After complete resection of ≤5 distant metastases, patients were randomly assigned to BCG+Canvaxin (BCG/Cv) or BCG+placebo (BCG/Pl). The primary endpoint was overall survival (OS); secondary endpoints were disease-free survival (DFS), and immune response measured by skin test (ClinicalTrials.gov identifier: NCT00052156). RESULTS: Beginning in May 1998, 496 patients were randomized. In April 2005, the Data Safety Monitoring Board recommended stopping enrollment due to a low probability of efficacy. At that time, median OS and 5-year OS rate were 38.6 months and 44.9%, respectively, for BCG/Pl versus 31.4 months and 39.6% in the BCG/Cv group (hazard ratio (HR), 1.18; p = 0.250). Follow-up was extended at several trial sites through March 2010. Median OS and 5-year and 10-year survival was 39.1 months, 43.3 and 33.3%, respectively, for BCG/Pl versus 34.9 months, 42.5 and 36.4%, in the BCG/Cv group (HR 1.053; p = 0.696). Median DFS, 5- and 10-year DFS were 7.6 months, 23.8 and 21.7%, respectively, for BCG/Pl versus 8.5 months, 30.0%, and 30.0%, respectively, for the BCG/Cv group (HR 0.882; p = 0.260). Positive DTH skin testing correlated with increased survival. DISCUSSION: In this, the largest study of postsurgical adjuvant therapy for stage IV melanoma reported to date, BCG/Cv did not improve outcomes over BCG/placebo. Favorable long-term survival among study patients suggests that metastasectomy should be considered for selected patients with stage IV melanoma.

RESUMO

BACKGROUND: Overactive bladder (OAB) syndrome with urinary incontinence (UI) is prevalent in the population and impairs health-related quality of life (HRQOL). OBJECTIVE: To assess the impact on efficacy, safety, and HRQOL of onabotulinumtoxinA (BOTOX(®), Allergan, Inc.) treatment in patients with OAB with UI. DESIGN, SETTING, AND PARTICIPANTS: This pivotal, multicentre, double-blind, randomised, placebo-controlled, phase 3 study enrolled patients with idiopathic OAB with ≥ 3 urgency UI episodes over 3 d and ≥ 8 micturitions per day who were inadequately managed by anticholinergics. INTERVENTION: OnabotulinumtoxinA at a 100U dose (n=277) or placebo (n=271), administered as 20 intradetrusor injections of 0.5 ml. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Co-primary end points were change from baseline in the number of UI episodes per day and proportion of patients reporting positive treatment response on the treatment benefit scale (TBS) at week 12. Additional end points included other OAB symptoms (episodes of urinary urgency incontinence, micturition, urgency, and nocturia) and HRQOL (Incontinence Quality of Life [I-QOL], King's Health Questionnaire [KHQ]). Safety assessments included adverse events (AEs), postvoid residual (PVR) urine volume, and initiation of clean intermittent catheterisation (CIC). RESULTS AND LIMITATIONS: OnabotulinumtoxinA significantly decreased UI episodes per day at week 12 (-2.95 for onabotulinumtoxinA versus -1.03 for placebo; p<0.001). Reductions from baseline in all other OAB symptoms were also significantly greater following onabotulinumtoxinA compared with placebo (p ≤ 0.01). Patients perceived a significant improvement in their condition, as measured by patients with a positive treatment response on the TBS (62.8% for onabotulinumtoxinA versus 26.8% for placebo; p<0.001). Clinically meaningful improvements from baseline in all I-QOL and KHQ multi-item domains (p<0.001 versus placebo) indicated positive impact on HRQOL. AEs were mainly localised to the urinary tract. Mean PVR was higher in the onabotulinumtoxinA group (46.9 ml versus 10.1 ml at week 2; p<0.001); 6.9% of onabotulinumtoxinA patients versus 0.7% of placebo patients initiated CIC. CONCLUSIONS: OnabotulinumtoxinA 100 U was well tolerated and demonstrated significant and clinically relevant improvements in all OAB symptoms, patient-reported benefit, and HRQOL in patients inadequately managed by anticholinergics. TRIAL REGISTRATION: ClinicalTrials.gov: NCT00910520.
