NCT06649110
A study to learn about the treatment LTP001 in healthy participants (Part A) and in participants with PAH (Part B)
NCT01142388
This randomized phase II trial studies how well paclitaxel with or without cixutumumab works in treating patients with esophageal cancer or gastroesophageal junction cancer that has spread to other places in the body (metastatic). Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Cixutumumab may kill cancer cells by blocking the action of a protein needed for cancer cell growth. Giving paclitaxel with or without cixutumumab may kill more tumor cells.
NCT01134614
This randomized phase II trial is studying how well giving ipilimumab with or without sargramostim (GM-CSF) works in treating patients with stage III or stage IV melanoma that cannot be removed by surgery (unresectable). Ipilimumab works by activating the patient's immune system to fight cancer. Colony-stimulating factors, such as sargramostim, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of treatment. It is not yet known whether giving ipilimumab together with sargramostim is more effective than ipilimumab alone in treating melanoma.
NCT03055338
This will be a randomized, placebo-controlled, parallel-group, multi-site, double-blind trial of elpipodect compared with placebo, using Risperidone as an active control. The participants will be adult subjects experiencing an acute episode of schizophrenia, according to the criteria specified in the Diagnostic and Statistical Manual of Mental Disorders, 5th ed. (DSM-5). This study will be up to 7 weeks in duration, with up to 7 site visits for each participant. The study will consist of a Screening/tapering period (up to one week long), a 4-week treatment period, and a 14-day follow-up period. The primary objective will be to assess symptoms of schizophrenia at 4 weeks, and to assess safety and tolerability during treatment and post-treatment follow-up. The secondary objective will be to assess the severity of schizophrenia at 4 weeks. The primary hypothesis is that elpipodect is superior to placebo in reducing the overall symptoms of schizophrenia as assessed by the mean change from baseline in the Positive and Negative Syndrome Scale (PANSS) total score after 4 weeks of treatment.
NCT06938841
Repetitive transcranial magnetic stimulation (rTMS) has emerged as a promising intervention for treatment-resistant depression (TRD), yet substantial uncertainties persist regarding its efficacy as a maintenance treatment. This prospective study seeks to investigate the efficacy of maintenance rTMS in individuals with TRD who have previously responded to an acute course of rTMS. In the R61 phase of the study, we will recruit 75 participants across three study sites, the University of California San Diego, Weill Cornell Medicine, and Australian National University, into a double-blind, three-arm maintenance treatment trial. In this trial, participants will be randomized to receive either standard maintenance rTMS, clustered maintenance rTMS, or sham maintenance rTMS for a duration of 6 months. Our primary aim is to examine the efficacy of maintenance rTMS on sustaining connectivity between the dorsolateral prefrontal cortex (DLPFC) and subgenual cingulate cortex (SGC) measured through concurrent TMS and electroencephalography (TMS-EEG) at baseline and every six weeks throughout the 6-month treatment period. We will also assess changes in depressive symptom severity using clinical scales, including the Montgomery-Asberg Depression Rating Scale (MADRS) as a secondary outcome measure. It is hypothesized that stimulation with clustered maintenance rTMS will demonstrate superiority in sustaining DLPFC-SGC connectivity compared with standard maintenance rTMS and sham maintenance rTMS

NCT06103487
RGX-111-5101 is a long-term follow up study that evaluates the long-term safety and efficacy of RGX-111 in participants who have received RGX-111 (a gene therapy intended to deliver a functional copy of the alpha-L-iduronidase gene (IDUA) to the central nervous system) in a separate parent study.
NCT05893862
The primary purpose of this study to evaluate the effect of a supratherapeutic dose of 80 mg elpipodect on the QT interval corrected for heart rate (QTc interval) and to assess the safety and tolerability of multiple once-daily doses of elpipodect in participants with schizophrenia. The effects of 3 treatment sequences 1) elpipodect (48 mg \[Day 1\] and 80 mg \[Day2\]); 2) standard image placebo (Day 1) and moxifloxacin 400 mg (Day 2); and 3) elpipodect placebo (Day 1 and Day 2) were assessed with 5-day washout intervening sequence. Participants received all treatments in a counter-balanced order according to 1 of 6 possible treatment sequences. The primary hypothesis is that the administration of an 80 mg elpipodect dose on Day 2 does not prolong the QTc interval to a clinically significant degree. Specifically, the true mean difference (elpipodect - placebo) in QTc change from baseline is less than 10 milliseconds (msec).
NCT06524414
The purpose of this study is to learn about the safety of a new pneumococcal vaccine and how the new pneumococcal vaccine helps to fight against germs in infants when compared to the pneumococcal vaccines that are currently in use, 20vPnC (Prevnar 20®) or another licensed pneumococcal vaccine. To ensure that the new vaccine (PG4) stays stable, it is placed in a liquid mixture of sterile water and other substances (a solution). This study will also test if there is a difference in the safety and immune effects of the new pneumococcal vaccine when it is one type of solution compared to when it is in a different type of solution. The immune response is how the body's cells; tissues and organs work together to protect the body from infection. Blood samples will be used to measure the amount of antibodies produced after the vaccination. Antibodies are proteins that protect you when an unwanted germ enters the body. This will help understand how well the new pneumococcal vaccine works. This vaccine can possibly provide protection against pneumococcal disease. Pneumococcal disease includes a variety of infections caused by a specific germ, Streptococcus pneumoniae. This study is seeking participants who are: * male or female infants who are 2 months of age, * infants born at 36 weeks (about 8 and a half months) of pregnancy or later; and, * said to be healthy by the study doctor There are four groups in this study. All participants will be assigned to one of the four groups. All study vaccines will be given as a single shot into the left thigh muscle. Participants in the three groups will have 3 blood samples collected during the 1 and a half years they are in the study. The first 400 participants who enter the study will be assigned to either Group 1 or Group 2. Half the participants in Group 1 and half the participants in Group 2 will receive 4 doses at 2, 4, 6, and 12 to 15 months of age of PG4 mixed in the first solution. The other half of the participants in Groups 1 and 2 will receive 4 doses of 20vPnC (Prevnar 20®) at 2, 4, 6, and 12 to 15 months of age. The main difference between Groups 1 and 2 is that participants in Group 2 will have the first blood sample collected at an earlier time than those in Group 1. Once 400 participants have been assigned to Groups 1 and 2 then 100 new participants will be assigned to Group 3. Half the participants in Group 3 will receive PG4 in the second solution at 2, 4, 6, and 12 to 15 months of age. The other half of the participants in Groups 3 will receive 4 doses of 20vPnC (Prevnar 20®) at 2, 4, 6, and 12 to 15 months of age. Once the 100 participants have been assigned to Group 3 then 300 new participants will be assigned to Group 4. Half the participants in Group 4 will receive PG4 in the first solution at 2, 4, 6, and 12 to 15 months of age. The other half of the participants in Group 4 will receive 4 doses of a licensed pneumococcal comparator vaccine at 2, 4, 6, and 12 to 15 months of age. Participants will take part in this study for about 16 to 19 months (about 1 and a half years). During this time, participants will have 6 study clinic visits and 1 to 2 phone calls. At these study clinic visits, parent(s) or legal guardian(s) will be asked if the participant experienced any side effects. A side effect is an unintentional or unexpected reaction to a vaccine.
NCT00265798
This phase II trial is studying how well sorafenib works in treating patients with malignant gastrointestinal stromal tumor that progressed during or after previous treatment with imatinib mesylate and sunitinib malate. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

NCT05765812
The primary purpose of the Phase 1 (Dose Escalation) of this study is to identify the dose-limiting toxicities (DLTs) of Debio 0123 combined with temozolomide (TMZ) (Arm A) and with TMZ and radiotherapy (RT) (Arms B and C) and to characterize the safety and tolerability of these combinations in adult participants with glioblastoma (GBM). Arm B which was previously added to the protocol, has been permanently halted per the safety monitoring committees' decision on the safety findings of this arm. The primary purpose of Phase 1 (Dose expansion) of the study is to assess the doses studied under Phase 1 (Dose Escalation) Arm A and identify the recommended dose (RD) for further development. The Phase 2 will start once the RD Phase 1 has been defined. The primary objective of Phase 2 is to assess the efficacy of Debio 0123 at the RD for further development in combination with TMZ, compared to the standard of care (SOC) in adult participants with GBM.
NCT06023459
This pilot trial will explore the feasibility, acceptability, and effectiveness of the most recently approved formulation of injectable extended-release buprenorphine (XR-BUP) for treatment of opioid use disorder (OUD) in rural settings. We will randomize 144 eligible individuals with moderate to severe OUD in a 2:1 ratio to one of two medication conditions: (1) XR-BUP (128mg target), administered every 4 weeks or (2) SL-BUP (16mg-24 mg/day target).Participants will receive study medication treatment for the 14 week-intervention period, including an initial \~2-week period of induction/stabilization. The study will use a mixed-methods approach (participant assessments, study medication records, qualitative interviews) for assessing feasibility and acceptability, and results will include patient outcome data on the comparative effectiveness of XR-BUP versus SL-BUP for patients with OUD in rural settings.
