A Study of TAR-200 in Combination With Cetrelimab, TAR-200 Alone, or Cetrelimab Alone in Participants With Non-Muscle Invasive Bladder Cancer (NMIBC) Unresponsive to Intravesical Bacillus Calmette-Guérin Who Are Ineligible for or Elected Not to Undergo Radical Cystectomy

Titre officiel

Phase 2b Clinical Study Evaluating Efficacy and Safety of TAR-200 in Combination With Cetrelimab, TAR-200 Alone, or Cetrelimab Alone in Participants With High-Risk Non-Muscle Invasive Bladder Cancer (NMIBC) Unresponsive to Intravesical Bacillus Calmette-Guérin (BCG) Who Are Ineligible for or Elected Not to Undergo Radical Cystectomy

Sommaire:

The purpose of this study is to evaluate the overall complete response (CR) rate in participants treated with TAR-200 in combination with cetrelimab (Cohort 1), or TAR-200 alone (Cohort 2), or cetrelimab alone (Cohort 3) with Carcinoma in Situ (CIS), with or without concomitant high-grade Ta or T1 papillary disease.

• Number of Participants with Adverse Events (AEs) by Severity Grades

Bladder cancer is the tenth most common type of cancer worldwide. The natural history of high-risk Non-Muscle Invasive Bladder Cancer (HR-NMIBC) is unpredictable; rates of recurrence vary from 15 percent (%) to 78%, and rates of progression to muscle invasion and metastasis vary from less than (<) 1 to 45%. The gemcitabine 225 milligrams (mg) intravesical delivery system (JNJ-17000139) product (hereafter, TAR-200) is an investigational product that is comprised of a drug and device components. Cetrelimab (JNJ-63723283) is a fully human immunoglobulin G4 (IgG4) kappa monoclonal antibody (mAb) that binds programmed-cell death protein 1 (PD-1). This study consists 3 periods: screening phase (up to 42 days); treatment phase (up to 2 years); follow up phase (up to 5 years). Total duration of study is up to 6 year and 7 months. Efficacy, safety, pharmacokinetics (PK), and biomarkers will be assessed at specified time points during this study.
