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 investigators are comparing two methods for helping improve everyday cognitive functioning in Canadian Armed Forces (CAF) veterans who have sustained a mild traumatic brain injury (mTBI). The two methods are 1) providing educational materials (Education Group) and 2) individual cognitive rehabilitation delivered by a trained Occupational Therapist or Speech-Language Pathologist (Therapy Group). The study is a pilot randomized controlled clinical trial (RCT), and will serve as pilot data for a future RCT.
A two-centre prospective cohort phase III study of 18F-PSMA-1007 PET/CT imaging in specific patient populations: 1. Adults patients (≥18 years old) with a history of radical prostatectomy for treatment of prostate cancer, and a serum prostate specific antigen (PSA) ≥ 0.2 mcg/L 2. Adult patients with a history of radiotherapy, cryotherapy, or brachytherapy for treatment of prostate cancer, and a serum PSA progressively rising to ≥ 2 mcg/L (minimum two samples) OR a serum PSA doubling time of < 9 months 3. Adult patients with a history of biopsy-proven prostate cancer and high-risk features for metastatic disease prior to treatment with radical prostatectomy, radiotherapy, cryotherapy, or brachytherapy. High-risk features include a Gleason score ≥ 7, serum PSA ≥ 20 mcg/L, OR minimum clinical T-stage T2c 4. Adult patients who do not meet criteria 1-3 but in whom a 18F-PDAM-1007 PET/CT scan is expected to provide clinical benefit as determined by a Urologist, Radiation Oncologist, Medical Oncologist, or Nuclear Medicine physician (licensed in Alberta) The safety of the investigational 18F-PSMA-1007 tracer will be evaluated in 3 ways: 1. The participant will be screened for adverse effects immediately post-injection 2. The participant will be screened for adverse effects immediately after the scan (approximately 2.5 hours after tracer injection) 3. The participant will be provided an information sheet and contact information for self-reporting of any delayed adverse events (1-7 days post injection) The incidence of and activity of non-specific bone lesions will be quantified and evaluated as follows: 1. All lesions categorized as non-specific bone lesions (PSMA-1007 SUVmax > 2.5 but no corresponding lesion on CT) will be recorded 2. The SUVmax and anatomic location will be recorded for each lesion (max 5 per participant) 3. Recorded lesions will be evaluated a minimum of 1 year post-scan to determine whether they are benign or malignant based on previously published reference standard criteria (Arnfield et al., 2021) 4. Equivocal lesions will be considered unevaluable and will be excluded from assessment of accuracy
This study is designed as a prospective comparative randomized clinical study to determine the diagnostic accuracy (sensitivity, specificity, positive predictive value, and negative predictive value) of pulsed fluoroscopy retrograde urethrogram for urethral stricture disease. The target population includes patients scheduled for retrograde urethrogram either new referral or follow up at Thunder Bay Regional Health Sciences Centre (TBRHSC) for treatment of urethral stricture who meet the specific eligibility criteria. The overall number of participants targeted will be 46. Upon presentation to the urology clinic or ambulatory care unit, the treating urologist/investigator will notify the patient of an opportunity to participate in the study. If the patient is interested, a research team member who is not directly involved in the patient care will be invited to discuss the study to the potential participant. The study team member will obtain a full-informed consent form the potential participant. Following informed consent, participants will be screened to ensure they meet the specific eligibility requirements of this study, through consultation with their medical records and the treating urologist. Randomization will be conducted in a 1:1 allocation ratio to either treatment arm: (1) the Pulsed fluoroscopy retrograde urethrogram, or (2) the Traditional retrograde urethrogram. Using an Excel sheet, the RAND function will give a random code. The random code is a figure ranging from 0.00000000 to 0.9999999999. A 0.5 cut-off code will be used, below which we will use the small blocks of 4 cells (4 rows of excel) and above which we will use the large blocks of 8 cells (8 rows of excel). Participants will undergo procedures according to the order of randomization Participants will undergo either Pulsed fluoroscopy retrograde urethrogram or Traditional retrograde urethrogram, depending on the treatment arm they are randomized to. Clinical data such as stricture location, stricture length and possible adverse effects will be recorded. According to the urologist decision based on data obtained during RUG, participant will be scheduled for urethroplasty or cystoscopy. All participants will undergo these procedures according to standard care procedures at TBRHSC. Data collection at baseline will include demographics, and relevant medical history. All retrograde urethrogram data including the type of urethrogram, the urethrogram date, fluoroscopy time, cumulative radiation dose, stricture location, stricture length and intraprocedural complications. Furthermore, we will record intraoperative data such as operative date, stricture location and stricture length. De-identified research files will be maintained in a secure office of a research team member during the conduct of the study. De-identified research data will be input into an electronic database that is password protected and maintained on research team member's computers or encrypted USB devices. An enrolment log, linking Participant ID to identifiable information will be maintained in hard copy in a locked office, or electronically as a password-protected document on the TBRHSC network. Only delegated research team members and the Principal Investigator will have access to research and patient data. Upon study closure, research records will be kept in secure storage in a research team member's office for a period of 5 years. Following this, the files will be securely shredded, and any electronic documents permanently deleted. Data will be analyzed using the commercially available SPSS software version 26 (SPSS Inc., Chicago, IL, USA). For both techniques, data obtained during baseline and postoperative urethrograms will be compared in terms of stricture location, stricture length, fluoroscopy time, cumulative radiation dose and the occurrence of intraprocedural complications. Categorical data will be compared using Chi-squared or Fisher test. Continuous data will be analyzed using the T test or Mann-Whitney U test Data obtained during urethroplasty will set as a standard of comparison to determine sensitivity, specificity, positive predictive value and negative predictive value of pulsed fluoroscopy and traditional urethrograms. For each comparison, 2 × 2 contingency tables were used to present the results and calculate the diagnostic accuracy estimates with 95% confidence intervals Data analysis will be done blindly regarding the type of performed procedure. One procedure will be coded as "1" and the other will "2". Categorical variables will be presented using number and percentage, and continuous variables will be presented using median and ranges. Two-tailed p-values of less than 0.05 will be set for statistical significance.
The purpose of this study is to compare the efficacy and safety of mezigdomide (CC-92480), bortezomib and dexamethasone (MeziVd) versus pomalidomide, bortezomib and dexamethasone (PVd) in participants with relapsed or refractory multiple myeloma (RRMM) who received between 1 to 3 prior lines of therapy and who have had prior lenalidomide exposure.
The rapid development of safe and effective COVID-19 treatment is a global health priority. Numerous studies evaluating therapies for this disease are currently underway, but the majority of these are in hospitalized patients with severe illness. Consequently, there is an urgent need to identify therapies that prevent mild COVID-19 cases in the community from becoming more severe. "Proning" or lying face down in bed has been shown to improve breathing and oxygen levels in COVID-19 patients, reducing the need for breathing tubes and ventilators and increasing survival. The current study will investigate whether proning and repositioning (lying on one's side or sitting up) can prevent mild cases of COVID-19 from becoming more severe resulting in fewer hospitalizations and death. A randomized controlled trial will be used to reduce the risk of bias when testing this intervention. Unvaccinated or partially vaccinated adult patients with a positive COVID-19 test willing to participate and well enough to be treated outside the hospital will be randomly assigned to one of two groups: a home-proning intervention group with instructions and daily reminders to prone and reposition during the day and at night, and a standard care group. Our goal is to assess whether home-proning/repositioning leads to fewer hospitalizations and death when compared with standard care. We'll also compare recovery time, use of antibiotics and follow up emergency department visits between these two groups. The current pilot study will assess the feasibility of a larger investigation or "main trial", meaning it will be small scale test of methods and procedures to be used on a larger scale.
