NCT02567435
This randomized phase III trial studies how well combination chemotherapy (vincristine sulfate, dactinomycin, cyclophosphamide alternated with vincristine sulfate and irinotecan hydrochloride or vinorelbine) works compared to combination chemotherapy plus temsirolimus in treating patients with rhabdomyosarcoma (cancer that forms in the soft tissues, such as muscle), and has an intermediate chance of coming back after treatment (intermediate risk). Drugs used 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. Combination chemotherapy and temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether chemotherapy plus temsirolimus is more effective than chemotherapy alone in treating patients with intermediate-risk rhabdomyosarcoma.
NCT06792539
The goal of this clinical trial is to evaluate the safety and effectiveness of the Polymotion Hip Resurfacing (PHR) System compared to total hip arthroplasty, for adults who require hip resurfacing arthroplasty due to 1) non-inflammatory arthritis (degenerative joint disease) such as osteoarthritis, traumatic arthritis, or 2) mild dysplasia/developmental dislocation of the hip (DDH) up to Crowe Grade 1.
NCT07435428
The purpose of this study is to assess the effectiveness and safety of a single dose of IPN10200 compared to placebo (double-blind phase) and how well and safely repeat doses of IPN10200 work over time (open-label phase) in adult participants with moderate to severe glabellar lines. Glabellar lines are wrinkle-like lines that appear between the eyebrows and can become more noticeable with age or repeated facial expressions. They may affect a person's appearance and confidence. All participants in the double-blind phase will receive IPN10200 or placebo during the first treatment cycle. De novo participants in the open-label phase will receive IPN10200 during the first treatment cycle. Some participants may receive additional treatment cycles with IPN10200 depending on their eligibility. There will be 3 periods in this study: * A screening period (up to 20 days) to assess whether the participant can take part, requiring at least 1 visit to the study centre. * A treatment period where participants may receive up to 4 treatment cycles. In the double-blind phase, participants receive a single treatment of IPN10200 or placebo. In the open-label phase (rollover participants from double-blind), eligible participants may receive additional cycles of IPN10200. In the open-label phase (de novo participants), participants will receive IPN10200 in the first cycle and eligible participants may receive additional cycles of IPN10200. Requires multiple visits during the first month followed by 1 visit every month. * A follow-up period (24 weeks) after the last injection where participants' health will be monitored. Participants will undergo health measurements and observation, including blood sampling, physical examinations, clinical evaluations and electrocardiograms (ECG: recording of the electrical activity of heart). They will also be asked to fill in questionnaires and keep a diary. Each participant will be in this study for up to 107 weeks. Participants may withdraw consent to participate at any time.

NCT06540963
The purpose of this study is to evaluate the investigational drug, tipifarnib (a pill taken by mouth), in combination with the Food and Drug Administration (FDA) approved drug, naxitimab, administered intravenously (IV; a liquid that continuously goes into your body through a tube that has been placed during a surgery into one of your veins). Naxitamab is FDA approved for pediatric patients 1 year of age and older and adult patients with relapsed or refractory high-risk neuroblastoma in the bone or bone marrow who have demonstrated a partial response, minor response, or stable disease to prior therapy, it may not be approved in the type of disease used in this study. The goals of this part of the study are: * Test the safety and tolerability of tipifarnib in combination with naxitimab in patients with cancer * To determine the activity of study treatments chosen based on: * How each subject responds to the study treatment * How long a subject lives without their disease returning/progressing
NCT04613128
This is a prospective, multi-center observational study. The study is designed to measure the clinical effectiveness of elexacaftor, tezacaftor and ivacaftor (ETI) triple combination therapy in children (6-11 years of old) with one or more copies of the F508del mutation, study the effects of ETI across a number of CF disease manifestations, and collect specimens for future research. Subjects in the study will have one "before ETI" visit within 30 days before initiation of the therapy and five "after ETI" visits over a 24-month follow-up period. Participants who have participated in the original PROMISE Pediatric Sub-Study have the option of participating in a long-term extension with annual visits performed at the 36- and 48-month timepoints. The durability of the clinical and biological changes in the PROMISE Pediatric Sub-Study can be assessed with extended follow-up, which would enable the sub-studies to consider potential clinical consequences of the biological or physiological effects being studied. This work will help to inform long term prognosis and feasibility of certain clinical trials outcomes for interventional studies and may be useful when considering research priorities in drug development. The duration of participation for each subject is 24 months (with an additional 24 months if participants agree to the optional long-term extension). NOTE: FDA has granted approval for elexacaftor, tezacaftor and ivacaftor in the 6-11 age group.

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.

The overall objective of the RESTORATiVE303 study is to evaluate the safety and the Clostridioides difficile infection (CDI) recurrence rate at Week 8 in participants who receive a 14-day course of VE303 or matching placebo. The objectives and endpoints are identical for Stage 1 (recurrent CDI) and Stage 2 (high-risk primary CDI).
NCT06814496
Phase I study to examine safety of the addition of concurrent tarlatamab with standard palliative and consolidative RT regimens , with a main cohort of N=20-24 patients with extracranial anatomic radiation sites. I) After lead in of 10 patients demonstrating safety of treatment, allow for expansion to cranial sites of disease (N=6-10) with continued enrollment in main cohort II) If toxicity criteria is not met in concurrent RT tarlatamab cohort, we will continue with sequential RT, either A) delivered within 7 days prior to cycle 1 day 1, or B) delivered during cycle 1 -2 but with pre- and post-RT washout of 7 days with no drug during RT, to examine safety in a temporally spaced setting. III) If sequential tarlatamab and radiation is not deemed safe, we would allow for continued enrollment to assess efficacy of drug sans radiation treatment, enriching for tumors not of small cell lung cancer histology and allowing for patients without sites amenable to RT. A nested phase II study will attempt to assess for ORR and safety of study intervention amongst tumors not of small cell lung cancer histology.
NCT04647253
AGENT IDE is a Prospective, Randomized (2:1), Multicenter Trial. The purpose of this study is to assess the safety and effectiveness of the Agent Paclitaxel Coated PTCA Balloon Catheter compared to balloon angioplasty (POBA) in patients with in-stent restenosis (ISR) of a previously treated lesion of up to 26 mm in length (by visual estimate) in a native coronary artery 2.0 mm to 4.0 mm in diameter.
NCT02150902
Atrial fibrillation (AF) is an abnormal heart rhythm in which the top chambers of the heart beat very fast. AF catheter ablation is a known technique to convert heart rhythm from AF to normal rhythm. The technique sends out electrical energy through a catheter (long thin round solid tubes) to destroy the heart tissues in a focused area where AF is starting. This technique is practiced at many hospitals, including the Heart Institute, and is not experimental. The AWARE study will compare two techniques of AF catheter ablation: 1. Ablation of tissues in wide circular bands around the opening of the pulmonary veins (bring blood back from lungs) in the left upper chamber of the heart. A medicine called adenosine will be given to unmask any incompletely ablated area. Additional ablations will be given if required. This is standard procedure. 2. Same as above but adenosine will not be used. Instead, additional ablation of a second circular band of tissues around the opening of the pulmonary veins will be given. This additional ablation is not standard procedure and is considered experimental. The Investigators are testing if adding more ablation sites will help maintain normal heart rhythm and reduce the rate of return to AF. The study will compare the occurrence of medical events and complications between the two groups. Identical supplies and equipment used in both techniques have been approved by Health Canada. Adenosine is currently approved by Health Canada for the treatment and diagnosis of arrhythmias. 396 participants from study sites across Canada will be randomly assigned "similar to flipping a coin" to treatment group 1 or group 2. After the ablation, participants will have study follow-up at 3, 6 and 12 months. All participant's will be followed for a minimum of 12 months.
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.
