Study of Cretostimogene Given in Patients With Non-Muscle Invasive Bladder Cancer ,Unresponsive to Bacillus-Calmette-Guerin

This is a Phase 3, open-label, single arm trial designed to evaluate Cretostimogene patients with NMIBC who have failed prior BCG therapy. Up to approximately 115 CIS bladder cancer patients with or without HG Ta or HG T1 papillary disease will be enrolled under the original protocol through Amendment 4, which will comprise Cohort C. Cohort C is closed to enrollment. Under Amendment 5-1, Cohort P was added to enroll up to 70 patients with HG Ta/T1 papillary bladder cancer. Under Amendment 6, the target number of patients enrolled in Cohort P was increased to 75. Cohort P is open to enrollment Cohort C and Cohort P will be analyzed and reported separately. Patients will have had to fail prior BCG therapy which is defined as having persistent or recurrent disease within 12 months (Cohort C) or 6 months (Cohort P) following the completion of adequate BCG therapy for HGUC

Study of Cretostimogene Given in Patients With Non-Muscle Invasive Bladder Cancer ,Unresponsive to Bacillus-Calmette-Guerin

This study aims to evaluate the efficacy and safety of Cretostimogene in patients with BCG-unresponsive high-risk non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS), with or without Ta/T1 papillary tumors.

A Study of Adjuvant Cretostimogene Grenadenorepvec for Treatment of Intermediate Risk NMIBC Following TURBT

This is a Phase 3, open-label, randomized trial designed to evaluate the RFS of TURBT followed by cretostimogene grenadenorepvec versus TURBT followed by surveillance for the treatment of participants with IR-NMIBC.

Hyperthermic Intravesical Chemotherapy (HIVEC) in BCG-Non-Responsive High-Grade NMIBC Patients

This is a Phase II, prospective, single-arm, open-label clinical study evaluating hyperthermic intravesical chemotherapy (HIVEC) with Mitomycin C in patients with high-grade, non-muscle-invasive bladder cancer (NMIBC) who are BCG-non-responsive or BCG-intolerant and are ineligible for, or refuse, radical cystectomy. Mitomycin C is an approved medicinal product used within routine clinical practice and administered with a CE-marked recirculation device (BRS Combat system) that maintains the solution at approximately 43°C for 60 minutes. The treatment schedule consists of 6 weekly induction instillations followed by 9 monthly maintenance instillations. The co-primary objectives are to describe the safety and toxicity profile of HIVEC, including treatment discontinuations due to procedure-related toxicity, and to estimate the 12-month recurrence-free survival (12moRFS). Secondary objectives include characterizing patterns of non-muscle-invasive and muscle-invasive recurrences, bladder cancer-specific survival, overall survival, and quality of life. Approximately 50 patients will be enrolled in this single-center pilot study to generate exploratory safety and efficacy data in this high-risk population and to support the design of future randomized trials

Efficacy of Gemcitabine Submucosal Injection for Preventing Recurrence in Intermediate- and High-Risk Non-Muscle-Invasive Bladder Cancer: A Randomized Trial

Bladder cancer is the most common malignant tumor of the urinary system in China, and its incidence has been increasing year by year. It is classified into non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC). NMIBC accounts for 75% of newly diagnosed bladder cancer cases, and transurethral resection of bladder tumor (TURBT) followed by postoperative intravesical therapy is the standard treatment for NMIBC. However, the 5-year recurrence rate of NMIBC remains as high as 50%, with 20-30% of patients progressing to MIBC. MIBC is characterized by rapid progression and a high tendency for metastasis. The 5-year survival rate for patients with metastatic bladder cancer is only 5.4%. This study aims to investigate the efficacy of submucosal injection of the chemotherapeutic agent gemcitabine in preventing recurrence of intermediate- and high-risk NMIBC. Additionally, it seeks to develop software and devices related to submucosal injection to promote the clinical application of this new approach in the chemotherapeutic management of NMIBC. This research is expected to bring a revolutionary breakthrough in the standardisation of whole-process diagnosis and treatment of NMIBC, holding significant scientific value and major clinical translational importance for improving therapeutic outcomes and prognosis of bladder cancer.

A Phase 1/1b Study of ZH9 Treatment in Patients With Non-Muscle Invasive Bladder Cancer

This is a first-in-human, multicenter, Phase 1/1b, 3-part, double-blind study of ZH9 in patients with recurrent NMIBC who are eligible for intravesical therapy. In Part 1, the safety, tolerability, and pharmacology of ZH9 IVI will be evaluated in a single ascending dose (SAD) patient cohort. In Part 2, the safety, tolerability, and pharmacology of ZH9 oral prime followed by ZH9 IVI will be evaluated in 2 patient cohorts at the doses and schedule established in Part 1. In Part 3, the safety, pharmacology, and clinical efficacy of ZH9 will be further evaluated in 2 expansion cohorts of patients with recurrent intermediate- and high-risk NMIBC.

A Study Comparing the Necessity of a Second Transurethral Resection in High-Risk Non-Muscle-Invasive Bladder Cancer Patients With Negative Results From Post-Initial Resection Urine Genome-Wide Low-Depth Sequencing

This study is a prospective, randomized, multicenter clinical trial aiming to enroll 428 patients with non-muscle-invasive bladder cancer (NMIBC) from the Department of Urology at Jiangsu Provincial People's Hospital and its affiliated centers, who have undergone their initial transurethral resection and are scheduled for a second resection. Within 1-6 weeks after the first resection and prior to the second resection, 100ml of routine urine will be collected and sent within 24 hours to Beijing Genetron Health Clinical Laboratory Co., Ltd. for the extraction of urinary sediment DNA, which will then undergo genome-wide low-depth sequencing. Patients with positive test results will proceed with the second resection, while those with negative results will be randomly assigned in a 1:2 ratio to either the intervention group, which will not undergo a second resection, or the control group, which will undergo the second resection. All enrolled patients will be followed up for two years. The study will statistically analyze and compare the two-year recurrence-free survival rates between the two groups and evaluate the predictive capability of the test results for follow-up recurrence.

Open Label Study to Evaluate the Safety and Efficacy of NDV01 KIT in High Grade NMIBC

This is a prospective, single-arm study evaluating the safety and efficacy of NDV01 KIT, a fixed-dose combination of gemcitabine HCl and docetaxel, administered via intravesical instillation in patients with high-grade Non-Muscle Invasive Bladder Cancer (NMIBC). NDV01 KIT includes 60 mL Carbopol Gel followed by 15 g NDV01 solution (gemcitabine HCl 1000 mg and docetaxel 40 mg), administered biweekly for six treatments, followed by monthly maintenance therapy for up to 12 months. The study includes a pharmacokinetic (PK) sub-study assessing systemic exposure to NDV01's active ingredients.

Follow up of Intravesical N-803 Plus BCG in BCG-Naive Non-Muscle Invasive Bladder Cancer (NMIBC)

The purpose of this clinical trial is to obtain long-term follow-up information and status of bladder cancer for patients who received study treatment in the QUILT-2.005 study.

The Necessity of a Second Transurethral Resection in High-risk Non-muscle-invasive Bladder Cancer Patients With Negative Urine Biomarker After Initial Transurethral Resection

The goal of this clinical trial is to evaluate the efficacy of using a urine biomarker test to guide the decision-making process regarding the necessity of reTURBT in NMIBC patients. The main question aims to answer whether patients with negative urine biomarker tests can safely avoid reTURBT without compromising recurrence-free survival. Participants who have completed the initial TURBT and tested negative for the urine biomarker will be enrolled in the study. They will then be randomized 1:2 into two groups:Group A: Participants will not receive reTURBT and Group B: Participants will undergo reTURBT. Researchers will compare the RFS rates between Group A (no reTURBT) and Group B (reTURBT) to determine if the urine biomarker test can safely spare patients from unnecessary reTURBT.
