A Phase Ib/II, Open-Label Study of the Safety and Pharmacology of Atezolizumab Administered With or Without Bacille Calmette-Guérin in Patients With High-Risk Non-Muscle-Invasive Bladder Cancer
Thomas A. Stamey Research Professor of Urology
Kathryn Simmons Stamey Professor, Emeritus
Inclusion Criteria:
- Histologically confirmed non-muscle-invasive transitional cell carcinoma (TCC) of the
bladder with carcinoma in-situ (CIS)
- High-risk NMIBC defined by the following:
BCG-unresponsive NMIBC:
Persistence of high-grade CIS at 6 months following an adequate course of BCG; or
Stage/grade progression at 3 months after induction BCG; or Recurrence of high-grade CIS
after achieving a disease-free state (i.e., CR) following induction of an adequate course
of BCG that occurs less than (<) 6 months after the last exposure to BCG
BCG-relapsing NMIBC:
Recurrence of high-grade CIS after achieving a disease-free state following induction of an
adequate course of BCG that occurs greater than or equal to (>/=) 6 months after the last
exposure to BCG
Very high-risk (VHR) BCG-naïve NMIBC:
VHR NMIBC, defined as having at least 1 of the following: Multiple and/or large (greater
than [>] 3 centimeters [cm]) T1, (HG/G3) tumors; T1, (HG/G3) tumor with concurrent CIS; T1,
G3 with CIS in prostatic urethra; Micropapillary variant of non-muscle invasive urothelial
carcinoma
- For BCG-unresponsive and BCG-relapsing NMIBC, participants must have received an
adequate course of BCG
- Resection of all pTa/pT1 papillary disease
- No prior radiation to bladder or pelvic region
- Eastern Cooperative Oncology Group (ECOG) performance status of less than or equal to
(
- Life expectancy >/=12 weeks
- Adequate hematologic and end-organ function
- Creatinine clearance >/=30 milliliters per minute (mL/min) (calculated using the
Cockcroft-Gault formula)
- For women of childbearing potential: agreement to remain abstinent (refrain from
heterosexual intercourse) or use contraceptive methods that result in a failure rate
of <1% per year during the treatment period and for at least 5 months after the last
dose of study drug. Women must refrain from donating eggs during this same period.
- For men receiving BCG: Agreement to remain abstinent (refrain from sexual intercourse)
or use a condom
- Tumor tissue biopsy within 60 days prior to study entry or availability of an archival
specimen obtained within 60 days of study screening
Exclusion Criteria:
- Evidence of locally advanced, metastatic, muscle-invasive, and/or extravesical bladder
cancer
- Any malignancy within 5 years prior to Cycle 1, Day 1
- History of autoimmune disease, idiopathic pulmonary fibrosis, organizing pneumonia
(e.g., bronchiolitis obliterans), drug-induced pneumonitis, idiopathic pneumonitis, or
active pneumonitis
- Signs or symptoms of infection within 2 weeks prior to the first dose of study
treatment
- Treatment with therapeutic oral or IV antibiotics within 2 weeks prior to the first
dose of study treatment
- Treatment with any approved anti-cancer therapy within 3 weeks prior to the first dose
of study treatment
- Treatment with any other investigational agent or participation in another clinical
trial with therapeutic intent within 4 weeks prior to the first dose of study
treatment
- Pregnant or lactating women, or women intending to become pregnant during the study
- Prior allogeneic stem cell or solid organ transplantation
- Positive test for human immunodeficiency virus (HIV)
- Active hepatitis B or C and/or tuberculosis
- Severe infections within 28 days prior to the first dose of study treatment
- Significant cardiovascular disease
- Major surgical procedure other than for diagnosis within 4 weeks prior to the first
dose of study treatment, or anticipation of need for a major surgical procedure during
the course of the study
- Administration of a live/attenuated vaccine within 4 weeks prior to the first dose of
study treatment, within 5 months following the administration of the last dose of
study drug, or anticipation that such a live/attenuated vaccine will be required
during the study
- History of prior significant toxicity or intolerance to BCG requiring discontinuation
of treatment
- History of prior systemic BCG infection
- History of immunosuppression, or conditions associated with congenital or acquired
immune deficiency
- Concurrent febrile illness, urinary tract infection, or gross hematuria
- Prior treatment with cluster of differentiation 137 (CD137) agonists or immune
checkpoint blockade therapies
- Treatment with systemic immunostimulatory agents within 6 weeks or five half-lives of
the drug, whichever is shorter, prior to the first dose of study treatment
- Treatment with systemic immunosuppressive medications within 2 weeks prior to the
first dose of study treatment, or anticipated requirement for systemic
immunosuppressive medications during the trial
