Active, not recruiting

• Conditions: Non Muscle Invasive Bladder Cancer

• Registration Number: NCT05981131
• Lead Sponsor: ImmunityBio, Inc.

Brief Summary

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.

Detailed Description

All 9 subjects that completed QUILT-2.005 phase 1b are planned to be enrolled in this study.

Thus, the maximum enrollment for this study is 9 subjects. All enrolled subjects will be followed every 12 months for life, or until withdrawal of consent, or if the Sponsor closes the study.

Primary Outcome Measures

Name	Time	Method
Assess the Complete response yearly	assessed up to 60 months	CR rate yearly following completion of QUILT-2.005 phase 1b for subjects with CIS disease with or without papillary disease at the initial diagnosis.; CR rate (as determined by the Investigator) yearly following completion of QUILT-2.005 phase 1b will be reported along with a two-sided exact 95% confidence interval. The exact confidence interval will be calculated using the Clopper-Pearson method.
Asses Disease-free Survival	assessed up to 60 months	To assess disease-free survival (DFS) since the first instillation of BCG plus N-803 in QUILT-2.005 phase 1b for subjects with papillary disease only at the initial diagnosis.; DFS (as determined by the Investigator) will be analyzed using Kaplan-Meier (KM) analysis methods. Subjects that are disease-free at the end of follow-up with censored at the last disease-free assessment
Obtain Long Term Follow-Up data to be summarized using descriptive statistics	assessed up to 60 months	Follow-up data on survival status, bladder cancer status (high-grade or low-grade), cystoscopy results (including number of cystoscopies done for each subject), biopsy results, upper tract evaluations, posttherapies and responses and outcomes of posttherapies, urine cytology results, and other medical history or treatments (if available) related to bladder cancer will be collected from subjects who were enrolled and treated in QUILT-2.005 phase 1b study with intravesical N-803 plus BCG.; Study endpoints will be summarized with descriptive statistics. Continuous variables will be summarized as mean, median, standard deviation, and minimum and maximum values. Categorical variables will be summarized as the number and percentage of subjects in each category. All confidence intervals will be constructed at the two-sided 95% level of confidence.
