Abstract Background Rezafungin (RZF) is a novel echinocandin exhibiting distinctive pharmacokinetics/pharmacodynamics. STRIVE was a phase 2, double-blind, randomized trial designed to compare the safety and efficacy of RZF once weekly (QWk) to caspofungin (CAS) once daily for treatment of candidemia and/or invasive candidiasis (IC). Methods Adults with systemic signs and mycological confirmation of candidemia and/or IC were randomized to RZF 400 mg QWk (400 mg), RZF 400 mg on week 1 then 200 mg QWk (400/200 mg), or CAS 70 mg as a loading dose followed by 50 mg daily for ≤ 4 weeks. Efficacy assessments included overall cure (resolution of signs of candidemia/IC + mycological eradication) at day 14 (primary endpoint), investigator-assessed clinical response at day 14, and 30-day all-cause mortality (ACM) (secondary endpoints), and time to negative blood culture. Safety was evaluated by adverse events and ACM through follow-up. Results Of 207 patients enrolled, 183 were in the microbiological intent-to-treat population (~21% IC). Overall cure rates were 60.5% (46/76) for RZF 400 mg, 76.1% (35/46) for RZF 400/200 mg, and 67.2% (41/61) for CAS; investigator-assessed clinical cure rates were 69.7% (53/76), 80.4% (37/46), and 70.5% (43/61), respectively. 30-day ACM was 15.8% for RZF 400 mg, 4.4% for RZF 400/200 mg, and 13.1% for CAS. Candidemia was cleared in 19.5 and 22.8 hours in RZF and CAS patients, respectively. No concerning safety trends were observed; ACM through follow-up was 15.2% (21/138) for RZF and 18.8% (13/69) for CAS. Conclusions RZF was safe and efficacious in the treatment of candidemia and/or IC.

In a randomized double-blind study fifty-four patients suffering from acute maxillary sinusitis were treated for 10 days with daily doses of sulphadiazine/trimethopim (1 g) and sulphamethoxazole/trimethoprim (1.92 g), respectively. The efficacy was evaluated clinically at two follow-up visits. X-ray investigations were performed at admission and after the therapy. Of thirty-nine patients finally evaluated, thirty-seven showed a favourable result. After 6–8 days of therapy there was significant difference in cure rates in favour of sulphadiazine/trimethoprim (p < 0.05) while the outcome as evaluated after treatment was similar for both drugs.

Sequential Analyses

Objective: Our aim was to assess the usefulness of cranberry extract in multiple sclerosis (MS) patients suffering from urinary disorders. Methods: In total, 171 adult MS outpatients with urinary disorders presenting at eight centers were randomized (stratification according to center and use of clean intermittent self-catheterization) to cranberry versus placebo in a 1-year, prospective, double-blind study that was analyzed using a sequential method on an intent-to-treat basis. An independent monitoring board analyzed the results of the analyses each time 40 patients were assessed on the main endpoint. Cranberry extract (36 mg proanthocyanidins per day) or a matching placebo was taken by participants twice daily for 1 year. The primary endpoint was the time to first symptomatic urinary tract infection (UTI), subject to validation by a validation committee. Results: The second sequential analyses allowed us to accept the null hypothesis (no difference between cranberry and placebo). There was no difference in time to first symptomatic UTI distribution across 1 year, with an estimated hazard ratio of 0.99, 95% CI [0.61, 1.60] ( p = 0.97). Secondary endpoints and tolerance did not differ between groups. Conclusion: Taking cranberry extract versus placebo twice a day did not prevent UTI occurrence in MS patients with urinary disorders. Trial Registration NCT00280592.

Abstract Background ASPECT-NP, a phase 3, randomized, double-blind study, evaluated C/T (at double the approved dose for other indications) vs. meropenem (MEM) in adults with ventilated nosocomial pneumonia. We compared safety and efficacy outcomes from this trial among patients with and without renal impairment (RI). Methods Patients were stratified by age and diagnosis and were randomized 1:1 to intravenous (IV) C/T 3 g every 8 h or IV MEM 1 g every 8 h. Study drug was administered for 8–14 days; doses were adjusted for moderate and severe RI. Eligible patients were mechanically ventilated; those on renal replacement therapy or with creatinine clearance (CrCL) < 15 mL/minute were excluded. Key efficacy endpoints included clinical cure rates at the test of cure (TOC) visit in the intent-to-treat (ITT) and clinically evaluable (CE) populations and Day 28 all-cause mortality (ACM) in the ITT population. In this analysis, patients were stratified based on renal function for outcome comparisons: normal renal function (CrCL ≥ 80 mL/minute); mild RI (CrCL > 50 to < 80 mL/minute); moderate RI (CrCL ≥ 30 to ≤ 50 mL/minute); and severe RI (CrCL ≥ 15 to < 30 mL/minute). Results A total of 726 patients were enrolled (C/T, N = 362; MEM, N = 364). Clinical cure rates at the TOC visit (CE and ITT populations) were robust across CrCL subgroups in both treatment arms and were similar based on 95% confidence intervals for treatment differences that included 0 (table). Day 28 ACM rates for patients with moderate and severe RI were numerically higher than those with mild RI in the MEM treatment arm. Rates of treatment-emergent adverse events (TEAEs) were similar in both treatment arms and across CrCL subgroups, with rates generally increasing with increasing RI severity. Rates of treatment-related TEAEs were low across treatment arms and CrCL subgroups with no treatment-related deaths reported. Conclusion Similar clinical cure and Day 28 ACM rates at the TOC visit were found across treatment groups for all CrCL subgroups, consistent with the overall primary and key secondary efficacy results for the ASPECT-NP study. Both drugs were well-tolerated. The results of this analysis indicate that the use of dose-adjusted C/T is appropriate in patients with nosocomial pneumonia and moderate or severe RI.

ObjectiveTo determine if chronic motor deficits secondary to traumatic brain injury (TBI) can be improved by implantation of allogeneic modified bone marrow-derived mesenchymal stromal/stem cells (SB623).MethodsThis 6-month interim analysis of the 1-year double-blind, randomized, surgical sham-controlled, phase 2 STEMTRA trial (NCT02416492) evaluated safety and efficacy of the stereotactic intracranial implantation of SB623 in patients with stable chronic motor deficits secondary to TBI. Patients in this multi-center trial (N = 63) underwent randomization in a 1:1:1:1 ratio to 2.5 × 106, 5.0 × 106, 10 × 106 SB623 cells or control. Safety was assessed in patients who underwent surgery (N = 61), and efficacy in the modified intent-to-treat population of randomized patients who underwent surgery (N = 61; SB623 = 46, control = 15).ResultsThe primary efficacy endpoint of significant improvement from baseline of Fugl-Meyer Motor Scale score at 6 months for SB623-treated patients was achieved. SB623-treated patients improved by (LS mean [SE]) +8.3 (1.4) vs +2.3 (2.5) for control at 6 months, the LS mean difference was 6.0 (95% CI: 0.3–11.8); p = 0.040. Secondary efficacy endpoints improved from baseline, but were not statistically significant vs control at 6 months. There were no dose-limiting toxicities or deaths, and 100% of SB623-treated patients experienced treatment-emergent adverse events vs 93.3% of control patients (p = 0.25).ConclusionsSB623 cell implantation appeared to be safe and well tolerated, and patients implanted with SB623 experienced significant improvement from baseline motor status at 6 months compared to controls.Classification of evidenceThis study provides Class I evidence that implantation of SB623 was well tolerated and associated with improvement in motor status.

Abstract Background Rezafungin is a novel echinocandin antifungal in development for treatment as well as prevention (prophylaxis) of invasive fungal infections. STRIVE (NCT02734862) is a global, randomized, double-blind, placebo-controlled, Phase 2 trial evaluating safety and efficacy of IV rezafungin once weekly (QWk) for treatment of candidemia and/or invasive candidiasis compared with standard-of-care (IV caspofungin once daily with optional oral stepdown). Here we report pharmacokinetic (PK) data from the completed STRIVE trial analyzed by patient demographics at baseline. Methods Rezafungin Day 8 trough (Cmin) concentrations from patients treated with rezafungin were summarized categorically by race (black or white), sex (male or female), and geographic region (North America [NA], or Europe [EU]), or plotted versus continuous variables of age, body weight, body mass index (BMI), and body surface area (BSA). As the first dose of rezafungin was 400 mg for all rezafungin-treated patients, data from both dose groups (Group 1: 400 mg QWk; Group 2: 400 mg in Week 1 followed by 200 mg QWk) were combined in this analysis. Results Rezafungin mean Cmin (SD) values were 1.8 (0.7) and 2.3 (1.2) in black and white patients, 1.9 (1.0) and 2.6 (1.2) in males and females, and 1.9 (0.6) and 2.4 (1.3) in patients from NA and EU. There were small differences in point estimates between the groups, but there was a great deal of overlap and the differences are not expected to be clinically meaningful (Figure). Similarly, no trends in Cmin values were observed across a range of ages (20-80 years), weights (~40-155 kg), BMI (~15-65 kg/m2), and BSA (~1.4-2.4 m2). Figure Conclusion No meaningful differences in rezafungin Cmin values were observed in patients grouped by sex, race, or geographic region, or across a wide range of patient factors, including age and body weight and size. These findings indicate that a single rezafungin dose regimen can be expected to provide consistent PK across diverse patient populations. Disclosures Shawn Flanagan, PhD, Cidara Therapeutics, Inc.

Objective. To compare the use of once-a-day cefpodoxime proxetil to once-a-day cefixime in the treatment of acute suppurative otitis media. Design. Randomized, multicenter, investigator-blinded. Setting. Outpatient. Patients. A total of 368 patients (age 2 months to 17 years) were randomized to receive either cefpodoxime or cefixime in a 2:1 ratio (245 cefpodoxime, 123 cefixime); 236 patients (155 cefpodoxime, 81 cefixime) were evaluable for drug efficacy. Interventions. Patients received either cefpodoxime proxetil oral suspension (10 mg/kg/day, once daily for 10 days) or cefixime oral suspension (8 mg/kg/day, once daily for 10 days). Main outcome measures. Clinical evaluations were performed before treatment (study day 1), at an interim visit (study day 3 through 6), at the end of therapy (study day 12 through 15), and at final follow-up (study day 25 through 38). Microbiologic evaluations were performed at enrollment and whenever appropriate thereafter. Results. End-of-therapy clinical cure rates in evaluable patients were 56% for the cefpodoxime group and 54% for the cefixime group. Clinical improvement rates were 27% for both groups. Clinical response rates were not significantly different between treatment groups (P = .541; 95% confidence interval = -8.1%, 15.2%). At long-term follow-up, 17% of patients in the cefpodoxime group and 20% in the cefixime group had a recurrence of infection. Drug-related adverse events (eg, diarrhea, diaper rash, vomiting, rash) occurred in 23.3% of cefpodoxime-treated patients and 17.9% of cefixime-treated patients (P = .282). Conclusions. These findings suggest that cefpo-doxime proxetil administered once daily is as effective and safe as cefixime given once daily in the treatment of acute suppurative otitis media in pediatric patients.
