3 Clinical Trials for Various Conditions
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
To evaluate the activity of intravesical administration of CG0070 and intravenous administration of Pembrolizumab in patients with tissue pathology-confirmed non-muscle invasive bladder cancer (NMIBC) who have Bacillus-Calmette-Guerin (BCG) unresponsive disease with carcinoma in situ (CIS) with or without Ta/T1 papillary disease.
Background: Non-muscle-invasive bladder cancer is in the early stages. But it usually comes back after treatment. The drugs Vicineum and Durvalumab may help the immune system find and destroy cancer cells. Objective: To test if the drugs Durvalumab and Vicineum together are safe and effective to treat people with bladder cancer that has not spread to the muscle in the bladder. Eligibility: People ages 18 and older who have bladder cancer that has not spread to the muscle in the bladder and was treated unsuccessfully with Bacillus Calmette-Guerin Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Tumor sample from previous surgery. If one is not available, they will have a biopsy: A small piece of tumor is removed. Cystoscopy to examine the inside of the bladder. This may include a biopsy or removing tumors. Computed tomography (CT) or magnetic resonance imaging (MRI): They lie in a machine that takes pictures of the body. Electrocardiogram to test heart function Participants will receive Durvalumab and Vicineum in 2 phases: First phase: Durvalumab every 4 weeks and Vicineum once a week for 3 months Second phase: Durvalumab every 4 weeks and Vicineum once every other week Participants will have tumor samples taken every 3 months. They will have blood and urine tests throughout the study. Participants will continue treatment for up to 2 years. Participants will have a visit about 30 days after their last treatment. This includes blood and urine tests. It may include a cytoscopy or additional biopsies.
