Summary

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.

Description

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 TAR-200/gemcitabine (JNJ-17000139-AAC) intravesical delivery system (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 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 5 years. Efficacy, safety, pharmacokinetics (PK), and biomarkers will be assessed at specified time points during this study.

Eligibility

Yes No Not Sure

Inclusion Criteria

Histologically confirmed diagnosis of persistent or recurrent high-risk, Non-muscle Invasive Bladder Cancer (HR-NMIBC) (carcinoma in situ [CIS]; Tumour in situ [Tis]), with or without papillary disease (T1, high-grade Ta) within 12 months of completion (last dose) of adequate Bacillus Calmette-Guerin (BCG) therapy. Mixed histology tumours are allowed if urothelial differentiation (transitional cell histology) is predominant (example, less than (<) 20 percent (%) variant histologic subtype). However, the presence of neuroendocrine, micropapillary, signet ring cell, plasmacytoid, or sarcomatoid features will make a participant ineligible. For participants with lamina propria invasion (T1) on the screening biopsy/ transurethral resection of bladder tumor (TURBT), muscularis propria must be present in order to rule out Muscle Invasive Bladder Cancer (MIBC)
Visible papillary disease must be fully resected (absent) prior to randomization (residual CIS acceptable) and documented at screening cystoscopy
Participants must be ineligible for or have elected not to undergo radical cystectomy
BCG-unresponsive high-risk NMIBC after treatment with adequate BCG therapy defined as a minimum of 5 of 6 doses of an induction course (adequate induction) plus 2 of 3 doses of a maintenance course, or 2 of 6 doses of a second induction course
Eastern Cooperative Oncology Group (ECOG) performance status Grade 0, 1, or 2

Exclusion Criteria

Histologically confirmed, muscle-invasive, locally advanced, nonresectable, or metastatic urothelial carcinoma (that is, T2, T3, T4, and/or Stage IV
Must not have had urothelial carcinoma or histological variant at any site outside of the urinary bladder. Ta/T1/CIS of the upper urinary tract (including renal pelvis and ureter) is allowable if treated with complete nephrouretrectomy more than 24 months prior to initiating study
Participants with an active, known or suspected autoimmune disease. Participants with autoimmune disorders not requiring systemic treatment (example, skin conditions such as vitiligo, psoriasis, alopecia) or conditions requiring hormonal replacement therapies such as type 1 diabetes mellitus or hypothyroidism are permitted to enroll
Active hepatitis B or C infection (for example, participants with history of hepatitis C infection but undetectable hepatitis C virus polymerase chain reaction (PCR) test and participants with history of hepatitis B infection with positive hepatitis B surface antigen (HBsAg) antibody and undetectable PCR are allowed)
Prior therapy with an anti-programmed cell death 1 (PD-1), anti-PD-ligand 2 (L2) agent, or with an agent directed to another co-inhibitory T-cell receptor
