Active clinical trials for "Urinary Bladder Neoplasms"

Based on the applicant's previous work and combined with the clinical medical resources of our unit, tumor cells were isolated from the lesion site of cancer patients, dendritic cells or macrophages were isolated from peripheral blood, and personalized chimeric exosome vaccine was prepared for patients. To evaluate the safety and tolerability of multiple administration of chimeric exosome vaccine in subjects with hatching or metastatic bladder cancer, explore the maximum tolerated dose (MDT) and dose-limiting toxicity (DLT) in humans, and recommend the safe dose range for the subsequent extended trials and subsequent clinical studies of this product. To reveal the "double-effect" improvement mechanism of chimeric exosome vaccine on the activation of immune response and the microenvironment of bladder cancer lesions, improve the anti-recurrence treatment effect of bladder cancer, and realize the clinical transformation of "double-target and double-effect" chimeric exosome vaccine in the field of individualized precision treatment of bladder cancer patients. To explore the clinical application value of this tumor therapeutic vaccine by using the T-cell receptor immunoomics and immunomolecular evaluation technology platform established by previous researchers, and to provide preliminary clinical research results for further vaccine development.

Intravesical immunotherapy or chemotherapy for non-muscle invasive bladder cancer is a well-established treatment for preventing or delaying tumor recurrence after bladder tumor resection. For high-risk non-muscle invasive bladder cancer, immunotherapy in the form of intravesical Bacillus Calmette-Guérin (BCG) can be effective as first-line, nevertheless, the response rate to BCG is suboptimal with many patients failing treatment. Following BCG-failure, however, very few effective therapeutic options exist besides life-changing cystectomy. In addition, nationwide shortages of BCG have pushed the use of alternative intravesical therapies for non-muscle invasive bladder cancer. At Banner University Medical-Tucson, the use of intravesical Gemcitabine is considered as standard treatment for patients with bladder cancer who are unable to get BCG or have failed prior BCG treatment. The role of Gemcitabine as treatment for NBMIC is poorly understood. The purpose of this study is to gain a better understanding of the use of Gemcitabine intravesical chemotherapy for non-muscle invasive bladder cancer in a prospective cohort of patients.

The purpose of this trial is to evaluate a new drug, HTL0039732, that will be administered on its own (as a monotherapy) and in combination with atezolizumab or with other approved anti-cancer therapies, in participants with advanced solid tumours.

The purpose of this study is to find out whether lattice radiation therapy (LRT) is an effective radiation therapy technique when compared to standard stereotactic body radiation therapy (SBRT). The study will also study how the different radiation therapy techniques (LRT and SBRT) affect how many immune cells are able to attack and kill tumor cells (immune infiltration).

The purpose of this study is to investigate the side effects, quality of life, and treatment effects of concurrent chemo-hypofractionated intensity-modulated radiation therapy in bladder cancer. Twenty fractionation within 4 weeks are performed using hypofractionated intensity-modulated radiation therapy. As for the radiation dose, 2.8-3.2 Gy at a time, total dose 56-64 Gy, to the high-risk target volume, and 2-2.2 Gy at a time, and 40-44 Gy, respectively, to the low-risk target volume. It aims to include more than 97% of the total dose to cover the entire PTV, and the minimum dose in the PTV is not lower than 95% of the prescribed dose, and the maximum dose does not exceed 107% of the prescribed dose. Chemotherapy before and after radiotherapy can be performed depending on the institutional policy. Among radiotherapy, chemotherapy is performed with platinum-based agents (cisplatin, carboplatin, etc.), and is administered once a week for a total of 3 or more.

This is a perioperative Phase 2, open-label, non-randomized, single-cohort study in patients with urothelial carcinoma of the bladder who cannot receive or refuse to receive cisplatin-based chemotherapy.

This is a single-arm, prospective, Phase II, multi-center clinical trial designed to demonstrate that adaptive radiotherapy for muscle invasive bladder cancer will translate into a decreased rate of acute gastrointestinal toxicity compared with the historically reported rate for non-adaptive intensity modulated radiation therapy (IMRT).

This is a single arm, Phase II trial involving the use of atezolizumab plus platinum and etoposide for patients with locally advanced urothelial cancer. The primary goal of this trial is to assess the pathologic complete response rate at cystectomy in patients after being treated with a combination therapy of atezolizumab, platinum, and etoposide.

A study of the efficacy and safety of probiotics in immunotherapy of urothelial carcinoma.

This phase Ⅰb/Ⅱ study evaluates the safety and efficacy of OH2 for adjuvant therapy in non-muscle-invasive bladder cancer after first-line prophylactic intravesical instillation therapy. OH2 is an oncolytic virus developed upon genetic modifications of the herpes simplex virus type 2 strain HG52, allowing the virus to selectively replicate in tumors. Meanwhile, the delivery of the gene encoding human granulocyte macrophage colony-stimulating factor (GM-CSF) may induce a more potent antitumor immune response.
