- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Patients must have histologically proven, recurrent, non-muscle invasive urothelial carcinoma of the bladder within 60 days prior to registration; the carcinoma must be stage T1 high-grade, stage CIS, or stage Ta high-grade
- Patients with mixed urothelial carcinoma and a glandular and/or squamous component will be eligible for the trial, but the presence of other histologic variants, pure adenocarcinoma, or pure squamous cell carcinoma, or pure squamous carcinoma in situ will make a patient ineligible
- Patients must have had all visible tumor resected completely within 60 days prior to registration; CIS disease is not expected to be completely excised; all patients must have tumor tissue from the histologic diagnosis of recurrence available for central pathology review submission; failure to submit these materials will make the patient ineligible for this study
- Patients must have had cystoscopy confirming no visible papillary tumor within 21 days prior to registration; (CIS disease is not expected to have been completely excised); if the transurethral resection of bladder tumor (TURBT) or bladder biopsy falls within 21 days of registration it will fulfill this criterion
- Patients must have had urine cytology within 21 days prior to registration; cytology for patients with CIS component is not expected to be negative for malignant cells; if the cytology for male patients with only Ta/T1 disease in the absence of CIS is positive for malignant cells, patient must have had a biopsy of the prostatic urethra within the previous six months
- All patients with T1 urothelial carcinoma at study entry must undergo re-TURBT within 60 days prior to registration, and must have evidence of uninvolved muscularis propria in the pathologic specimen from either the first or the second TURBT; tissue from the re-resection must be submitted for central review in addition to the tissue from the first TURBT; the TURBT that identified the recurrent T1 disease may have taken place more than 60 days prior to registration but not more than 120 days; patients with high grade Ta or CIS do not require a re-TURBT, but if this is performed at the discretion of the treating physician, the second TURBT must be within 60 days of registration; there is no requirement for muscularis propria in the specimen of Ta/CIS patients, but the tissue from the first and second TURBTs must be submitted for central review; if a patient with Ta/T1 disease undergoes repeat TURBT, the patient will be stratified as having CIS if there is CIS on either TURBT

- Patients must not have had urothelial carcinoma in the prostatic urethra within the previous 24 months or muscle invasive urothelial carcinoma of the bladder at any time; patients with prior urothelial carcinoma in the upper urinary tract within the previous 24 months will only be eligible if they had =< T1 carcinoma and were treated with nephroureterectomy; patients must have a computed tomography (CT) or magnetic resonance imaging (MRI) (including CT-intravenous pyelogram [IVP], CT-urogram or MR-urogram) of the abdomen and pelvis to rule out upper tract malignancy and intra-abdominal metastases within 90 days prior to registration; if a patient cannot tolerate intravenous contrast, a retrograde pyelogram should be performed within 90 days prior to registration
- Patients must be deemed unfit for radical cystectomy by the treating physician, or the patient must refuse radical cystectomy, which is considered standard of care for these patients; the reason for patients not to undergo cystectomy will be clearly documented
- Patients must be BCG-unresponsive; a patient is BCG-unresponsive if they meet one or more of the following criteria:
- Patient has persistent or recurrent high-grade Ta/CIS urothelial carcinoma after completing therapy with at least induction BCG (>= 5 doses) and first round maintenance (>= 2 doses) or second induction BCG (>= 2 doses); both rounds of BCG must have been administered within a 12 month period; these patients must have either had high-grade Ta tumors and did not achieve a disease-free state for more than 6 months following last dose of BCG, or they had CIS and did not achieve a CR; S1605 registration must occur within 9 months of the last dose of BCG
- If a patient does not meet these criteria only because the last dose of BCG was more than 9 months ago, the patient may become eligible if he/she shows histologically proven high-grade recurrence after an additional round of induction or maintenance BCG (>= 3 doses) within 9 months prior to registration
- Patient has persistent or recurrent high grade T1 urothelial carcinoma after completing therapy with at least induction BCG (>= 5 doses); patients with recurrent high grade T1 urothelial carcinoma after additional rounds of BCG will also be eligible, but one round of maintenance therapy or a second induction is not a pre-requisite for these patients. Trial registration must occur within 9 months of the last dose of BCG
- If a patient does not meet these criteria only because the last dose of BCG was more than 9 months ago, the patient may become eligible if he/she shows histologically proven high grade recurrence after an additional round of induction or maintenance BCG (>= 3 doses) within 9 months prior to registration
- Patient achieves disease-free state at 6 month time point (i.e., complete response; presence of only low-grade tumor at this timepoint is still considered complete response) after induction and maintenance (or second round of induction) BCG but later experiences a high-grade Ta/T1 recurrence (with or without concomitant CIS) within 6 months after the last dose of BCG or recurrent CIS (in absence of concomitant Ta/T1 tumor) within 12 months after the last BCG dose; the time of eligibility is measured from the last dose of BCG to the time of disease recurrence; the patient must be registered on the trial within 60 days of this recurrence, or within 60 days of a re-TURBT if indicated
- All adverse events associated with any prior surgery and intravesical therapy must have resolved to grade =< 2 prior to registration
- Absolute neutrophil count (ANC) >= 1,500 microliter (mcL) (within 42 days prior to registration)

- Patients must have Zubrod performance status =< 2
- Patients must have a baseline electrocardiograph (ECG) performed within 42 days prior to registration
- Patients positive for human immunodeficiency virus (HIV) are eligible only if they have all of the following:

About this study
Official title: Phase II Trial of Atezolizumab in BCG-Unresponsive Non-Muscle Invasive Bladder Cancer
This phase II trial studies how well atezolizumab works in treating patients with non-muscle invasive bladder cancer that has come back (recurrent) and has not responded to treatment (refractory) with Bacillus Calmette-Guerin (BCG). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
Read the detailed description
PRIMARY OBJECTIVE:
- To estimate complete response at 25 weeks after registration for those with a carcinoma in situ (CIS) component and to evaluate event-free survival at 18 months in patients with BCG-unresponsive high-risk non-muscle invasive bladder cancer (Ta/T1/CIS) treated with atezolizumab.
SECONDARY OBJECTIVES:
- To estimate event-free survival at 18 months for the subset of patients with papillary cancer (Ta/T1).
II. To estimate progression-free survival, cystectomy-free survival, bladder cancer-specific survival, overall survival in all patients.
ADDITIONAL OBJECTIVES:
- To estimate the level of agreement between local and central pathology review in terms of recurrence (for all patients) and complete response (for the CIS subset).
II. To identify markers that predict response to atezolizumab in the CIS population and that are associated with event-free survival (EFS) in patients with Ta/T1/CIS BCG-unresponsive non-muscle invasive bladder cancer. The following markers will be tested:
IIIa. Expression of PD-L1 and CD8 by immunohistochemistry (IHC). IIIb. Expression of immune signatures by ribonucleic acid (RNA)-sequencing (RNA-seq).
IIIc. Peripheral immune response by mass cytometry (CyTOF) and TruCulture.
OUTLINE:
Patients receive atezolizumab intravenously (IV) over 60 minutes on day 1. Treatment repeats every 21 days for up to 17 cycles (51 weeks) in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 12 weeks for 2 years and then every 24 weeks for 3 years.

What is being measured
The primary outcome is the main question the study is designed to answer.
Complete Response (CR) Rate in the Subset of Patients With Carcinoma in Situ (CIS)
To estimate complete response at 25 weeks after registration for those with a CIS component. Complete Response (CR) is defined as negative biopsy for high grade disease at Week 25 (± 7 days) for the subset of patients with a CIS component at study entry, according to local pathology call. In addition, patients with a CIS component who undergo negative biopsy at Week 13 for suspicious cystoscopy and or positive cytology and have cystoscopy not suspicious for cancer and cytology not positive for malignant cells at Week 25 do not require repeat biopsy at Week 25 and will be considered to have a complete response at Week 13 and will also be counted as having a complete response at Week 25.
Measured: At 25 weeks
Event-free Survival (EFS)
To evaluate event-free survival at 18 months in patients with BCG-unresponsive high-risk non-muscle invasive bladder cancer (Ta/T1/CIS) treated with atezolizumab. Event-Free Survival is defined as time from date of registration to first documentation of event. Participants last known to be alive and not to have recurred are censored at the date of last contact. An event was defined as the first occurrence of any of the following: biopsy-proven high-grade bladder cancer (including persistent CIS at 3 and/or 6 months); high-grade upper tract urothelial carcinoma; high-grade urothelial carcinoma of the prostatic urethra; muscle-invasive disease; clinical evidence of metastatic disease; or death due to any cause.
Measured: 18 months
Secondary outcomes (5)
Event-free Survival (EFS) in the Ta/T1 Subset
To evaluate event-free survival at 18 months in the subset of participants with papillary cancer (Ta/T1) treated with atezolizumab. Event-Free Survival is defined as time from date of registration to first documentation of event. Participants last known to be alive and not to have recurred are censored at the date of last contact. An event was defined as the first occurrence of any of the following: biopsy-proven high-grade bladder cancer (including persistent CIS at 3 and/or 6 months); high-grade upper tract urothelial carcinoma; high-grade urothelial carcinoma of the prostatic urethra; muscle-invasive disease; clinical evidence of metastatic disease; or death due to any cause.
Measured: 18 months
Progression-free Survival (PFS)
To evaluate progression-free survival at 18 months in all eligible and evaluable participants. Progression-free survival (PFS) is defined as the time from registration to first evidence of biopsy-proven muscle-invasive bladder cancer (T>=2), nodal or distant metastasis, or death from any cause. Participants without an event were censored at the date of their last cystoscopy. Estimated using Kaplan-Meier.
Measured: 18 months
Time to Cystectomy
Time to cystectomy is defined as time from discontinuation of protocol therapy to time of cystectomy.
Measured: Up to 5 years
Bladder Cancer-Specific Survival
To evaluate bladder cancer-specific survival at 3 years in all eligible and evaluable participants. Bladder cancer-specific survival is defined as the time from registration to death due to bladder cancer. Participants without bladder cancer death are censored at last contact date or date of non-bladder cancer death. Estimated using Kaplan-Meier.
Measured: 3 years
Three-Year Overall Survival
Overall survival (OS) is defined as the time from registration to the date of death due to any cause. Participants last known to be alive are censored at the date of last contact.
Measured: 3 years
