There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to obtain ovarian tissue from female patients undergoing gonadotoxic treatments or gonadal ablating surgery, and that in consequence may see their future fertility impaired. Participants will be offered to preserve (freeze) and use ovarian tissue for the purpose of conceiving in the future. Although, 86 live births have been reported with ovarian tissue cryo-preservation and grafting, the procedure is still considered experimental. This research, will help us to learn and validate how to perform ovarian tissue cryo-preservation and thawing in the fertility preservation context.
The study purpose is to assess various protein blends, which differ in protein quality, and the impact on blood amino acid response in male subjects.
This is a 2-arm, randomized, open-label, international, multicenter study comparing the efficacy of ripretinib to sunitinib in GIST patients who progressed on or were intolerant to first-line anticancer treatment with imatinib. Approximately 426 patients will be randomized in a 1:1 ratio to ripretinib 150 mg once daily (continuous dosing for 6 week cycles) or sunitinib 50 mg once daily (6 week cycles, 4 weeks on, 2 weeks off).
Psychological factors such as stress, distress, anxiety, depression, and poor coping strategies may be associated with ongoing pain following injuries such as fractures. To study this relationship, patients will undergo cognitive behavioural therapy (CBT) which is designed to modify such thoughts with the goal of reducing ongoing pain and improving quality of life. The goal of this study is to determine if CBT, versus usual care, reduces the prevalence of moderate to severe persistent post-surgical pain (PPSP) over 12-months post-fracture
This observational study is designed to collect urine and relevant clinical information from patients who have a known diagnosis of bladder cancer and currently on clinically driven surveillance. The study aims to compare the urine test to the flexible cystoscopy procedure (which the patient is already scheduled).
This is a randomized controlled trial, comparing 3 months of intensive leg exercise to standard physiotherapy care for the improvement of gross motor function in young children with spastic diplegia.
A prospective, single blind, parallel group, randomized control trial to determine if early, intensive lower extremity activity delivered by a physical therapist and a parent in partnership improves gross motor function more than usual care.
The study will evaluate the efficacy of the Rehabilitation Planning Consult (RPC) to achieve key rehabilitation outcomes in survivors of head and neck cancer compared to a waiting list control group. The RPC is a consultative intervention that teaches survivors to use self-management and problem solving strategies to meet and attain individualized goals. Follow-through with plans and goal attainment are facilitated by a Rehabilitation Consultant. Results from this study will be used to plan for a larger multi-site trial and subsequent real world implementation.
Treatment of glioblastoma involves an optimal surgery, followed by a combination of radiation and temozolomide chemotherapy. Progression-free survival (PFS) with this treatment is only 6.9 months and relapse is the norm. The rationale behind the fact that limited chemotherapy agents are available in the treatment of malignant gliomas is related to the blood-brain barrier (BBB), which limits drug entry to the brain. Intraarterial (IA) chemotherapy allows to circumvent this. Using IA delivery of carboplatin, the investigators have observed responses in 70% of patients for a median PFS of 5 months. Median survival from study entry was 11 months, whereas the overall survival 23 months. How can this be improved? By coupling radiation with a chemotherapeutic which is also a potent radiosensitizer such as carboplatin. Study design: In this phase I/II trial, patients will be treated at recurrence; a surgery will be performed for cytoreduction and to obtain tumor sample, followed with a combination of re-irradiation and IA carboplatin chemotherapy. A careful escalation scheme from 1.5Gy/fraction up to 3.5Gy/fraction will allow the investigators to determine the optimal re-irradiation dose (10 fractions of radiation over 2 weeks). Toxicity will be assessed according to the NCIC common toxicity criteria. Combined with radiation, patients will receive 2 treatments of IA carboplatin, 400 mg/m2, 4 hours prior to the first and the sixth radiation fraction. IA treatments will then be continued on a monthly basis, up to a total of 12 months, or until progression. Outcome measurements: Tumor response will be evaluated using the RANO criteria by magnetic resonance imaging monthly. The investigators will also acquire a sequence that enables the measurement of cerebral blood flow, cerebral blood volume and blood vessel permeability that are all relevant to understand the delivery of therapeutics to the CNS. Primary outcome will be OS and PFS. Secondary outcome will be QOL, neurocognition, and carboplatin delivery. In vitro intracellular carboplatin accumulation: Tumor samples from re-operation will be be analyzed for intracellular Pt concentration by ICP-MS. The amount of Pt bound to DNA will be measured. The level of apoptosis will be determined for each of the sample. Putting together these data will allow to correlate clinical and radiological response to QOL, NC (MOCA), and to delivery surrogates for the IA infusion and intracellular penetration of carboplatin.
NTM therapy consists of a multi-drug macrolide based regimen for 18-24 months. Treated patients frequently experience debilitating side effects, and many patients delay the start of antibiotic treatment due to these risks. Common side effects include nausea, diarrhea, and fatigue, and rare but serious toxicities include ocular toxicity, hearing loss, and hematologic toxicity. To date, most of the evidence underlying the current treatment recommendations has come from observational studies in which either a macrolide has been combined with rifampin and ethambutol, or in some cases combined with ethambutol alone. The proposed study will answer whether a third drug is necessary or whether taking two drugs can increase tolerability without a substantial loss of efficacy.
