Filter by:Study design This study is a Phase III, randomized, open-label, multi-center, global study to determine the efficacy of a single immediate intravesical chemotherapy instillation (SI) in the prophylaxis of intravesical recurrence after diagnostic uretero-renoscopy (URS) of patients 18 years of age or older with the fist diagnosis of UTUC. This study will randomize 394 patients globally Patients will be randomized in a 1:1 ratio to the interventional arm or to observation. Study period This study will include a screening period, a treatment and disease assessment period, safety follow-up visits and a 5-year survival follow-up period to begin immediately after the treatment. Screening period: The period up to 28 days prior to intervention during which the screening procedures occur. Treatment and disease assessment period: The period starting the day of diagnostic URS (Day 0) during which patients receive their assigned treatment (Day 0 to day 1) and disease assessments are performed. All patients must follow the disease assessment schedule, which includes disease assessments at screening and every 3 months (±1 week) from the date of intervention until 24 months from the date of randomization, and then every 6 months for up to 5 years. The treatment and disease assessment period will end at the time of intravesical recurrence, death, or MINERVA-CTU decision to terminate the trial early. Safety follow-up visits: Every patient in this study will be assessed for the occurrence of adverse events (AEs) and serious adverse events from the time of signed informed consent until 90 days after the administration of SI. All patients who receive SI will have safety visits 4, 8, and 12 weeks following administration of SI. Safety assessments include targeted physical examination, complications according to Dindo-Clavien classification and patient-reported outcomes (PRO) assessments. Survival follow-up period: Patients will be followed up at in-clinic site visits, by telephone contact, or by contact with the patient's current physician for up to 5 years from the date of randomized into this study. Objectives Primary objective Efficacy of a SI in the prophylaxis of intravesical recurrence after diagnostic URS for UTUC Secondary objectives - Time to intravesical recurrence - 5-years intravesical recurrence rates - Incidence of high-grade BCa recurrence - Incidence and gravity of adverse events (AEs) due to the SI - To collect and store blood, urine and tissue samples according to each country's local and ethical procedures for identifying candidate markers that may correlate with likelihood of clinical benefit (optional) - To collect and store DNA according to each country's local and ethical procedures for future exploratory research into somatic mutations and genes/genetic variations that may influence oncologic outcomes, to study treatments and susceptibility to disease (optional) - To assess disease-related symptoms and HRQoL in patients with UTUC treated with SI compared those undergoing observation - To assess patient-reported treatment tolerability directly using specific PRO-CTCAE symptoms Target study population The study population includes patients 18 years of age or older with a primary diagnosis of UTUC, scheduled for diagnostic URS Duration of treatment Patients randomized to the interventional arm will receive a SI within 24h after diagnostic URS. In case of multiple diagnostic URS during the follow-up (including 2nd look for incomplete ablation, non-diagnostic first URS or UTUC recurrence) patients randomized to the interventional arm will receive a SI after each diagnostic URS for 2 years after the day of first diagnostic URS. Follow-up of subjects post discontinuation of study treatment Patients who have discontinued study treatment due to toxicity, symptomatic deterioration, intravesical recurrence or investigator's decision will be followed up for survival until 5 years from the date of diagnostic URS. Survival All randomized patients, regardless of disease status, will be followed up for survival until 5 years from the date of diagnostic URS. Investigational product, dosage, and mode of administration Patients randomized to the interventional arm will receive a SI. The chemotherapy will be at investigator's discretion and institutional availability. The selected chemotherapy must be approved by the MINERVA-CTU in discussion with the local investigator. Statistical methods This study will randomize 394 patients globally. Patients will be randomized 1:1 to SI or observation. Randomization will be stratified by the following factors: 1. Center 2. EAU UTUC risk stratification
To study the feasibility of using magnetic resonance imaging (MRI) in evaluation UB wall thickening after transurethral resection (TUR) of bladder cancer.
This study will be carried out to examine the effect of telephone-assisted smoking cessation program on self-efficacy, smoking behavior, tumor recurrence and progression in patients with non-muscle invasive bladder cancer.
To evaluate the effects of local intravesical B.C.G and gemcitabine on semen quality and testicular volume.
miRNAs have been detected in different bodily fluids, which suggests significant potential, such as their use as biomarkers in diagnostics and prognostics. Sha-mir-71a was abundantly found in the urine of patients with bladder cancer as compared to benign bladder cystitis associated with schistosomiasis . Additionally, this miRNA was more highly detected in urine samples from patients with bilharzial bladder cancer than bladder cancer not associated with bilharziasis (schistosomiasis), suggesting its specificity in the identification of bladder cancer associated with infection.
Patients with metastatic bladder cancer are usually treated with chemotherapy. If their cancers do not progress after chemotherapy, they can be enrolled into this study and receive a standard-of-care immunotherapy medication named avelumab plus a study drug named copanlisib.
This trial will evaluate the use of combination pembrolizumab and enfortumab vedotin for patients with high grade non-metastatic (cN0/NxMx, no measurable regional lymph nodes, no metastases) upper tract urothelial cancer (UTUC), preferring to forego standard of care radical nephroureterectomy (RNU) surgery. Currently these patients would not be suitable candidates for neoadjuvant trials, as the patients intention is to forego surgery. The patients are also not candidates for metastatic trials, as the patients have no measurable metastasis. The Investigators hypothesize the combination of pembrolizumab and enfortumab vedotin for patients with high grade cN0/NxMx UTUC deferring RNU will lead to event free survival outcomes similar to that achieved by RNU in a historic dataset.
Investigation of delay in postoperative mobilization due to motor block and complications related to block in patients who underwent USG-assisted obturator nerve block with distal approach
For patients with high-risk non-muscle-invasive bladder cancer (NMIBC), intravesical therapy of BCG is the standard treatment proved to reduce the risk of recurrence and progression. However, there are patients failed to complete the whole treatment due to the long period and some patients showed no response to BCG or suffered tumor progression after BCG treatment. The aim of this study is to examine the efficacy and safety of intravesical therapy of BCG combined with PD-1 monoclonal antibody as the treatment of high-risk NMIBC patients without BCG treatment. At the same time, transcriptome sequencing is used to analyze the correlation between the efficacy of the treatment and the level of immune cell infiltration and tumor molecular subtypes.
This project will conduct a large-sample, multi-center prospective clinical trial to further establish the safety and efficacy of BL-5ALA-PDT in preventing Non-Muscle Invasive Bladder Cancer (NMIBC) recurrence when compared to the usual postoperative perfusion chemotherapy regimen.
