Dalbavancin for the Treatment of Osteomyelitis in Adult Patients: A Randomized Clinical Trial of Efficacy and Safety.

ABSTRACT: Background:Osteomyelitis is a challenging infection that can involve 4-6 weeks of intravenous (IV) antibiotics. Dalbavancin, approved for acute bacterial skin and skin structure infections, has potent activity against gram-positive pathogens. This study assessed the efficacy and safety of dalbavancin as a 2-dose regimen for osteomyelitis. Methods:This study was a randomized, open-label, comparator-controlled trial in adults with a first episode of osteomyelitis defined by clinical symptoms, radiologic findings, and elevated C-reactive protein. Patients were randomized 7:1 to dalbavancin (1500 mg IV on days 1 and 8) or standard of care (SOC) for osteomyelitis (oral or IV) per investigator judgment for 4-6 weeks. The primary endpoint was clinical response at day 42, defined as recovery without need for additional antibiotics in the clinically evaluable (CE) population. Clinical response was also assessed at day 21, 6 months, and 1 year. Results:Eighty patients were randomized to dalbavancin (n = 70) or SOC (n = 10). All had baseline debridement; Staphylococcus aureus was the most common pathogen (60% of patients). Clinical cure at day 42 was seen in 65/67 (97%) and 7/8 (88%) patients in the dalbavancin group and SOC group in the CE population, respectively. Clinical response was similar in the dalbavancin group at day 21 (94%), 6 months, and 1 year (96%). Treatment-emergent adverse events occurred in 10 patients in the dalbavancin group; no patient discontinued treatment due to an adverse event. Conclusions:A 2-dose regimen of weekly dalbavancin is effective and well tolerated for the treatment of osteomyelitis in adults. Clinical Trials Registration:NCT02685033.

Project description:Importance:Ozenoxacin, a novel topical antibacterial agent with potent bactericidal activity against gram-positive bacteria, has been developed as a cream with 1% active drug for the treatment of impetigo, a highly contagious bacterial skin infection. Objectives:To evaluate the efficacy, safety, and tolerability of ozenoxacin cream, 1%, after 5-day twice-daily topical treatment in patients with impetigo. Design, Setting, and Participants:This randomized, double-blind, vehicle-controlled clinical trial included patients 2 months or older with impetigo who were enrolled at centers in 6 countries from June 2, 2014, through May 30, 2015. Data were analyzed based on intention to treat from July 9 through July 22, 2015. Interventions:Patients were randomized 1:1 to receive topical ozenoxacin or placebo control. Main Outcomes and Measures:Efficacy was measured using the Skin Infection Rating Scale and microbiological culture. Safety and tolerability were also evaluated. Results:Among the 411 patients who received treatment (210 males [51.1%]; mean [SD] age, 18.6 [18.3] years), ozenoxacin demonstrated superior clinical success compared with placebo, which was evident after 5 days of therapy (112 of 206 [54.4%] vs 78 of 206 [37.9%]; P = .001). Ozenoxacin also demonstrated superior microbiological success compared with placebo after 2 days of therapy (109 of 125 [87.2%] vs 76 of 119 [63.9%]; P = .002). Ozenoxacin was well tolerated, with 8 of 206 patients experiencing adverse effects, with only 1 of these potentially related to the study treatment; none were serious. Conclusions and Relevance:Topical ozenoxacin is effective and well tolerated in the treatment of impetigo in patients 2 months and older. This effect is demonstrated by rapid onset of response and superior clinical and microbiological response compared with placebo. Topical ozenoxacin represents a novel option for the treatment of impetigo. Trial Registration:ClinicalTrials.gov Identifier: NCT02090764.

Project description:ImportanceIndividuals living with schizophrenia are affected by cardiometabolic, endocrine, and motor adverse effects of current antipsychotic medications. Lumateperone is a serotonin, dopamine, and glutamate modulator with the potential to treat schizophrenia with few adverse effects.ObjectiveTo examine the efficacy and safety of lumateperone for the short-term treatment of schizophrenia.Design, setting, and participantsThis randomized, double-blind, placebo-controlled, phase 3 clinical trial was conducted from November 13, 2014, to July 20, 2015, with data analyses performed from August 13 to September 15, 2015. Patients with schizophrenia who were aged 18 to 60 years and were experiencing an acute exacerbation of psychosis were enrolled from 12 clinical sites in the United States.InterventionsPatients were randomized 1:1:1 (150 patients in each arm) to receive lumateperone tosylate, 60 mg; lumateperone tosylate, 40 mg (equivalent to 42 or 28 mg, respectively, of the active moiety lumateperone); or placebo once daily for 4 weeks.Main outcomes and measuresThe prespecified primary efficacy end point was mean change from baseline to day 28 in the Positive and Negative Syndrome Scale (PANSS) total score vs placebo. The key secondary efficacy measure was the Clinical Global Impression-Severity of Illness (CGI-S) score. The PANSS subscale scores, social function, safety, and tolerability were also assessed.ResultsThe study comprised 450 patients (mean [SD] age, 42.4 [10.2] years; 346 [77.1%] male; mean [SD] baseline PANSS score, 89.8 [10.3]; mean [SD] baseline CGI-S score, 4.8 [0.6]). In the prespecified modified intent-to-treat efficacy analysis (n = 435), 42 mg of lumateperone met the primary and key secondary efficacy objectives, demonstrating a statistically significant improvement vs placebo from baseline to day 28 on the PANSS total score (least-squares mean difference [LSMD], -4.2; 95% CI, -7.8 to -0.6; P = .02; effect size [ES], -0.3) and the CGI-S (LSMD, -0.3; 95% CI, -0.5 to -0.1; P = .003; ES, -0.4). For 28 mg of lumateperone, the LSMD from baseline to day 28 was -2.6 (95% CI, -6.2 to 1.1; P = .16; ES, -0.2) on the PANSS total score and -0.2 (95% CI, -0.5 to 0.0; P = .02; ES, -0.3) on the CGI-S. Both lumateperone doses were well tolerated without clinically significant treatment-emergent motor adverse effects or changes in cardiometabolic or endocrine factors vs placebo.Conclusions and relevanceLumateperone demonstrated efficacy for improving the symptoms of schizophrenia and had a favorable safety profile.Trial registrationClinicalTrials.gov identifier: NCT02282761.

Project description:Importance:It remains uncertain whether vitamin C routinely used with oral iron supplements is essential for patients with iron deficiency anemia (IDA). Objective:To compare the equivalence and assess the safety of oral iron supplements plus vitamin C or oral iron supplements alone in patients with IDA. Design, Setting, and Participants:This single-center, open-label, equivalence randomized clinical trial was conducted from January 1, 2016, to December 30, 2017, in Huashan Hospital, Fudan University. Adult patients with newly diagnosed IDA were enrolled. Participants were randomly assigned (1:1) to the oral iron supplements plus vitamin C group or the oral iron supplements-only group. Data analysis was performed from March to December 2018. Interventions:Patients were randomized to receive a 100-mg oral iron tablet plus 200 mg of vitamin C or a 100-mg iron tablet alone every 8 hours daily for 3 months. Main Outcomes and Measures:The primary outcome was the change in hemoglobin level from baseline to 2 weeks of treatment, and an equivalence margin of 1 g/dL in hemoglobin was chosen for the demonstration of comparable efficacy. Secondary outcomes included the change in the reticulocyte percentage after 2 weeks of treatment, the increase in hemoglobin level after 4 weeks of treatment, the increase in serum ferritin level after 8 weeks of treatment, and adverse events. Results:Among the 440 randomized patients (220 each in the oral iron supplements plus vitamin C group and iron-only group; 426 women [96.8%]; mean [SD] age, 38.3 [11.7] years), all were assessed for the primary outcome, and 432 (98.2%) completed the trial. From baseline to the 2-week follow-up, the mean (SD) change in hemoglobin level was 2.00 (1.08) g/dL in the oral iron supplements plus vitamin C group and 1.84 (0.97) g/dL in the oral iron supplements-only group (between-group difference, 0.16 g/dL; 95% CI, -0.03 to 0.35 g/dL), thus meeting the criteria for equivalence. The mean (SD) change in serum ferritin level from baseline to 8-week follow-up was 35.75 (11.52) ng/mL in the vitamin C plus iron group and 34.48 (9.50) ng/mL in the iron-only group (between-group difference, 1.27 ng/mL; 95% CI, -0.70 to 3.24 ng/mL; P?=?.21). There were no significant differences between the 2 groups regarding the rates of adverse events (46 [20.9%] vs 45 [20.5%]; difference, 0.4%; 95% CI, -6.7% to 8.5%; P?=?.82). No patient withdrew because of adverse events. Conclusions and Relevance:Among patients with IDA, oral iron supplements alone were equivalent to oral iron supplements plus vitamin C in improving hemoglobin recovery and iron absorption. These findings suggest that on-demand vitamin C supplements are not essential to take along with oral iron supplements for patients with IDA.

Project description:ImportanceRimabotulinumtoxinB (RIMA) may be preferable as an anti-sialorrhea treatment compared with current oral anticholinergic drugs in people with neurological disorders.ObjectiveTo assess the safety, efficacy, and tolerability of RIMA injections for the treatment of sialorrhea in adults.Design, setting, and participantsThis randomized, parallel, double-blind, placebo-controlled clinical trial of RIMA 2500 U and 3500 U was conducted from November 14, 2013, to January 23, 2017. A total of 249 adult patients with troublesome sialorrhea secondary to any disorder or cause were screened. Of them, 13 refused further participation in the study or were lost to follow-up and 49 did not fulfill the criteria for participation; 187 were ultimately enrolled. Patients had to have a minimum unstimulated salivary flow rate (USFR) of 0.2 g/min and a minimum Drooling Frequency and Severity Scale score of 4.ExposuresPatients were randomized 1:1:1 to RIMA, 2500 U (n = 63); RIMA, 3500 U (n = 64); or placebo (n = 60).Main outcomes and measuresPrimary outcomes were the change in USFR from baseline to week 4 and the Clinical Global Impression of Change (CGI-C) at week 4. The CGI-C scores were recorded on a 7-point scale ranging from very much improved to very much worse. Adverse events were recorded throughout the trial period.ResultsOf 187 patients enrolled (147 men [78.6%]; mean [SD] age, 63.9 [13.3] years), 122 patients had Parkinson disease (65.2%), 13 (7.0%) were stroke survivors, 12 had amyotrophic lateral sclerosis (6.4%), 6 had medication-induced sialorrhea (3.2%), 4 had adult cerebral palsy (2.1%), and 30 had sialorrhea owing to other causes (16.0%). A total of 176 completed the study. Treatment with both doses of RIMA significantly reduced USFR at week 4 vs placebo (mean treatment difference, -0.30 g/min [95% CI, -0.39 to -0.21] for both doses vs placebo, P < .001). The CGI-C scores were statistically significantly improved at week 4 for both treatment groups vs placebo (-1.21 [95% CI, -1.56 to -0.87] for 2500 U, -1.14 [95% CI, -1.49 to -0.80] for 3500 U, both P < .001). Treatment benefits were seen as early as 1 week after injection and were maintained over the treatment cycle of approximately 13 weeks. The RIMA injections were well tolerated compared with placebo. The most common adverse events were self-limited mild to moderate dry mouth, dysphagia, and dental caries.Conclusions and relevanceTreatment with RIMA (2500 U and 3500 U) in adults was well tolerated and reduced sialorrhea, with the onset of the effect at 1 week after the injection. These data support the clinical use of RIMA in the management of sialorrhea in adults.Trial registrationClinicalTrials.gov Identifier: NCT01994109.

Project description:IntroductionThe current standard treatment for patients with Duchenne muscular dystrophy (DMD) involves corticosteroids. Granulocyte colony-stimulating factor (G-CSF) induces the proliferation of satellite cells and myoblasts and, in turn, muscle regeneration. Beneficial effects of G-CSF were also described for skeletal muscle disorders.AimWe assessed the safety and effects of using G-CSF to promote muscle strength in patients with DMD.Materials and methodsInclusion criteria were as follows: patients aged 5-15 years with diagnosed with DMD confirmed by genetic test or biopsy. Fourteen patients were treated with steroids, and their use was not changed in this study. Diagnoses were confirmed by genetic tests: deletions were detected in 11 patients and duplications in 5 patients. Nineteen 5- to 15-year-old patients diagnosed with DMD-9 were in wheelchairs, whereas 10 were mobile and independent-completed an open study. Participants received a clinical examination and performed physiotherapeutic and laboratory tests to gage their manual muscle strength, their isometric force using a hand dynamometer, and aerobic capacity [i.e., 6-min walk test (6MWT)] before and after therapy. Each participant received G-CSF (5 µg/kg/body/day) subcutaneously for five consecutive days during the 1st, 2nd, 3rd, 6th, and 12th month. Laboratory investigations that included full blood count and biochemistry were performed. Side effects of G-CSF treatment were assessed during each visit. During each cycle of G-CSF administration in the hospital, rehabilitation was also applied. All patients received regular ambulatory rehabilitation.ResultsThe subcutaneous administration of G-CSF improved muscle strength in participants. We recorded a significant increase in the distance covered in the 6MWT, either on foot or in a wheelchair, increased muscle force in isometric force, and a statistically significant decrease in the activity of the muscle enzyme creatine kinase after nearly every cycle of treatment. We observed no side effects of treatment with G-CSF.ConclusionOur findings suggest that G-CSF increases muscle strength in patients with DMD, who demonstrated that G-CSF therapy is safe and easily tolerable.

Project description:ImportanceThere is clinical equipoise for COVID-19 convalescent plasma (CCP) use in patients hospitalized with COVID-19.ObjectiveTo determine the safety and efficacy of CCP compared with placebo in hospitalized patients with COVID-19 receiving noninvasive supplemental oxygen.Design, setting, and participantsCONTAIN COVID-19, a randomized, double-blind, placebo-controlled trial of CCP in hospitalized adults with COVID-19, was conducted at 21 US hospitals from April 17, 2020, to March 15, 2021. The trial enrolled 941 participants who were hospitalized for 3 or less days or presented 7 or less days after symptom onset and required noninvasive oxygen supplementation.InterventionsA unit of approximately 250 mL of CCP or equivalent volume of placebo (normal saline).Main outcomes and measuresThe primary outcome was participant scores on the 11-point World Health Organization (WHO) Ordinal Scale for Clinical Improvement on day 14 after randomization; the secondary outcome was WHO scores determined on day 28. Subgroups were analyzed with respect to age, baseline WHO score, concomitant medications, symptom duration, CCP SARS-CoV-2 titer, baseline SARS-CoV-2 serostatus, and enrollment quarter. Outcomes were analyzed using a bayesian proportional cumulative odds model. Efficacy of CCP was defined as a cumulative adjusted odds ratio (cOR) less than 1 and a clinically meaningful effect as cOR less than 0.8.ResultsOf 941 participants randomized (473 to placebo and 468 to CCP), 556 were men (59.1%); median age was 63 years (IQR, 52-73); 373 (39.6%) were Hispanic and 132 (14.0%) were non-Hispanic Black. The cOR for the primary outcome adjusted for site, baseline risk, WHO score, age, sex, and symptom duration was 0.94 (95% credible interval [CrI], 0.75-1.18) with posterior probability (P[cOR<1] = 72%); the cOR for the secondary adjusted outcome was 0.92 (95% CrI, 0.74-1.16; P[cOR<1] = 76%). Exploratory subgroup analyses suggested heterogeneity of treatment effect: at day 28, cORs were 0.72 (95% CrI, 0.46-1.13; P[cOR<1] = 93%) for participants enrolled in April-June 2020 and 0.65 (95% CrI, 0.41 to 1.02; P[cOR<1] = 97%) for those not receiving remdesivir and not receiving corticosteroids at randomization. Median CCP SARS-CoV-2 neutralizing titer used in April to June 2020 was 1:175 (IQR, 76-379). Any adverse events (excluding transfusion reactions) were reported for 39 (8.2%) placebo recipients and 44 (9.4%) CCP recipients (P = .57). Transfusion reactions occurred in 2 (0.4) placebo recipients and 8 (1.7) CCP recipients (P = .06).Conclusions and relevanceIn this trial, CCP did not meet the prespecified primary and secondary outcomes for CCP efficacy. However, high-titer CCP may have benefited participants early in the pandemic when remdesivir and corticosteroids were not in use.Trial registrationClinicalTrials.gov Identifier: NCT04364737.
