NCT04581434
Many people who have posttraumatic stress disorder (PTSD) also struggle with problematic alcohol or drug use (substance use disorders \[SUD\]). Patients with both conditions prefer PTSD be treated alongside SUD. However, clinicians don't know if treatments that have been found to help those with PTSD work as well for people who also have SUD. This often leads to delaying PTSD treatment or using psychotherapies without research support. Trauma-focused psychotherapy (TFT) is the type of psychotherapy for PTSD that has been studied most often among people with both PTSD and SUD. It reduces symptoms of PTSD and substance use, although it might not work as well in those who have SUD as those who do not. Further, many patients with both PTSD and SUD do not complete TFT. Another strategy for treating PTSD is non-trauma-focused psychotherapy (NTFT). One NTFT, Present Centered Therapy, has been found to reduce symptoms of PTSD and more patients are able to complete NTFT than are able to finish TFT. However, no one has studied how well Present Centered Therapy works among patients who also have SUD. We will test which approach (TFT of NTFT) is better for reducing symptoms of PTSD and which is more likely to be completed by patients with both PTSD and SUD at VA healthcare facilities. We will also test to see whether some participants did better than others, so we can learn how to individualize treatment recommendations to patients. Participants will be assigned by chance to either TFT of NTFT. Patients assigned to TFT will receive either Prolonged Exposure or Cognitive Processing Therapy; both are weekly psychotherapies focused on addressing thoughts and/or memories related to their trauma. Those assigned to NTFT will receive Present Centered Therapy, a weekly psychotherapy in which patients learn about how PTSD relates to their current difficulties and problem solve current life difficulties. All participants will also receive SUD treatment. Participants will answer questions about their symptoms and experience with treatment before, right after they finish, and three and six months after they finish PTSD treatment. At the end of the study we will compare which treatment approach worked better to decrease PTSD symptom severity and which treatment patients were better able to complete. We will also track other outcomes that are important to patients (e.g., how they are doing in their relationships).
NCT03719690
An international, multicenter, open-label, 2 cohort, non-comparative, pivotal study evaluating the efficacy of tipifarnib in HRAS mutant HNSCC (AIM-HN). The first cohort will assess the objective response rate (ORR) of tipifarnib in subjects with HNSCC with HRAS mutations. The second study cohort, SEQ-HN, is an observational sub-study including HNSCC patients in whom HRAS mutations were not identified (wild type HRAS HNSCC) and who consent to provide first line outcome data and additional follow up.
NCT04772313
This is a Phase 4, multicenter, open-label trial of pegloticase with methotrexate (MTX) in adult participants with uncontrolled gout who were previously treated with pegloticase without a concomitant immunomodulator and stopped pegloticase due to failure to maintain serum uric acid (sUA) response and/or a clinically mild infusion reaction (IR). Approximately 30 participants will be enrolled. Pegloticase + MTX will be administered for approximately 24 weeks, with an optional extension up to 48 weeks. The trial design will include 5 distinct components: 1. Screening Period, lasting up to 42 days; 2. 6-week MTX Tolerability Assessment Period (hereafter referred to as the MTX Run-in Period); 3. 24-week Pegloticase + MTX Treatment Period, which will include a Week 24/End of Trial/Early Termination Visit (subjects that end MTX and pegloticase treatment prior to the Week 24 will remain on trial for follow up until the Week 24 visit) 4. Optional Pegloticase + MTX Extension Period up to 24 weeks 5. 30-Day Post Treatment Follow -up
NCT03635957
The overall objective of the study is to assess the efficacy, safety, tolerability, and pharmacokinetics (PK) of the concomitant use of pegloticase with methotrexate (MTX) to enhance the response rate seen with pegloticase alone in adults with uncontrolled gout.
NCT04347720
Patent ductus arteriosus (PDA) is the most common cardiovascular problem that develops in preterm infants. Persistent PDA may result in higher rates of death, chronic lung disease (CLD), pulmonary hemorrhage, necrotizing enterocolitis (NEC), acute kidney injury (AKI), intraventricular hemorrhage (IVH) and cerebral palsy. Currently available options to treat a PDA include indomethacin, ibuprofen or acetaminophen followed by surgical or interventional closure of the PDA if medical therapy fails. Wide variation exists in PDA treatment practices across Canada. A survey conducted through the Canadian Neonatal Network (CNN) in 2019 showed that the most common choice of initial pharmacotherapy is standard dose ibuprofen. In view of the high pharmacotherapy failure rate with standard dose ibuprofen, there is a growing use of higher doses of ibuprofen with increasing postnatal age (with 32% of respondents currently adopting this practice) in spite of the fact that effectiveness and safety of higher ibuprofen doses have not been established in extremely preterm infants \[\<29 weeks gestational age (GA)\]. In view of this large practice variation across Canadian neonatal intensive care units (NICUs), we are planning a comparative effectiveness study of the different primary pharmacotherapeutic agents used to treat the PDA in preterm infants. Aims Primary: To compare the primary pharmacotherapeutic practices for PDA closure and evaluate their impact on clinical outcomes in extremely preterm infants (\<29 weeks GA) Secondary: To understand the relevance of pharmacotherapeutic PDA treatment with respect to clinical outcomes in the real world. Methods: Participants: Extremely preterm infants (\<29 weeks gestational age) with an echocardiography confirmed PDA who will be treated according to attending team Interventions: 1. Standard dose ibuprofen \[10-5-5 regimen, i.e., 10mg/kg followed by 2 doses of 5mg/kg at 24h intervals\] 2. Adjustable dose ibuprofen \[10-5-5 regimen if treated within the first week. Higher doses of ibuprofen up to a 20-10-10 regimen if treated after the postnatal age cut-off for lower dose as per the local center policy\] 3. Intravenous indomethacin \[0.1-0.3mg/kg every 12-24h for a total of 3 doses\]. 4. Acetaminophen \[Oral/intravenous\] (15mg/kg every 6h) for 3-7 days Outcomes: Primary: Failure of primary pharmacotherapy (Need for further medical and/or surgical/interventional treatment following an initial course of pharmacotherapy). Secondary: (a) Receipt of 2nd course of pharmacotherapy; (b) Surgical/interventional PDA closure; (c) CLD (d) NEC (stage 2 or greater) (e) Severe IVH (Grade III-IV) (f) Definite sepsis (g) Stage 1 or greater AKI; (h) Post-treatment serum bilirubin; (i) Phototherapy duration; (j) All-cause mortality during hospital stay.
NCT03070522
This will be a 5 year randomized, double blind, placebo controlled trial of 7 days of oral prednisone in cystic fibrosis (CF) patients receiving intravenous (IV) antibiotic treatment for a pulmonary exacerbation at the Hospital for Sick Children and other study sub-sites across Canada. The intervention will be oral prednisone 2 mg/kg/day (max 60 mg) divided twice daily for 7 days as an adjunctive therapy for pulmonary exacerbations in CF patients who have not recovered their baseline forced expiratory volume in 1 second (FEV1) after 7 days of IV antibiotic treatment. The primary outcome will be the proportion of subjects who achieve \>90% of their baseline FEV1 % predicted at day 14 of IV antibiotic treatment for a pulmonary exacerbation in each treatment arm.
NCT03689244
Selexipag is available in many countries for the treatment of pulmonary arterial hypertension (PAH). Due to the similarities between PAH and chronic thromboembolic pulmonary hypertension (CTEPH) and the observed efficacy of other PAH medicines in CTEPH, it is believed that selexipag could benefit to patients with CTEPH. This study aims to assess the efficacy and safety of selexipag in participants with inoperable or persistent/recurrent CTEPH.
NCT03927690
The primary objectives of this study were to evaluate the safety and efficacy of LKA651 in patients with macular edema from diabetic macular edema (DME),
NCT03610724
The purpose of the study was to assess the efficacy and safety of tisagenlecleucel in pediatric, adolescent and young adult patients with relapsed/refractory B-cell non-Hodgkin lymphoma (r/r B-NHL) including Burkitt Lymphoma and Burkitt Leukemia. For pediatric patients who have r/r B-NHL including Burkitt Lymphoma and Burkitt Leukemia, survival rates are dismal, only \~20-50% subjects are alive at 2 years with overall response rate (ORR) of 20-30% after conventional salvage chemotherapy.
NCT05948475
This study is a Phase III, Randomized, Controlled, Global Multicenter Study to Evaluate the Efficacy and Safety of Oral Tinengotinib versus Physician's Choice in Subjects with Fibroblast Growth Factor Receptor (FGFR)-altered, Chemotherapy- and FGFR Inhibitor-Refractory/Relapsed Cholangiocarcinoma
NCT04410523
The purpose of this study is to determine the efficacy and safety of multiple CSJ117 doses (0.5; 1; 2; 4 and 8 mg) inhaled once daily compared with placebo, when added to standard-of-care (SoC) asthma therapy in adult patients with uncontrolled asthma with respect to change from baseline in FEV1 at the end of 12 weeks of treatment.
