Functional Imaging of T-Cell Activation With [18F]F-AraG in Urothelial Carcinoma Patients Receiving Neoadjuvant Therapy or Patients With Cancer Receiving Standard of Care Anti-PD-1/L1
Condition: Bladder Cancer
Intervention:
- Drug: Fluorine F 18 Ara-G
- Procedure: Positron Emission Tomography
- Procedure: Magnetic Resonance Imaging
Purpose: This phase II trial studies how well fluorine F 18 Ara-G positron emission tomography (PET)/magnetic resonance (MR) imaging works in measuring clinical response to atezolizumab or patients with cancer receiving standard of care Anti-PD-1/L1. Diagnostic procedures, such as fluorine F 18 Ara-G PET/MR imaging, may help measure a patient’s response to standard of care atezolizumab or Anti-PD-1/L1 treatment.
Study Type: Interventional
Clinical Trials Identifier NCT 8-digits: NCT03007719
Sponsor: Lawrence Fong
Primary Outcome Measures:
- Measure: The change between pre-treatment and post-treatment SUVmax (Standardized Uptake Values) in the primary and/or metastatic tumor(s) on whole-body [18F]F-AraG PET/MR (Positron Emission Tomography/Magnetic Resonance) imaging.
- Time Frame: Baseline up to day 8
- Safety Issue:
Secondary Outcome Measures:
- Measure: Change in maximum standard uptake value (SUVmax)
- Time Frame: Baseline up to day 8
- Safety Issue:
- Measure: The change between pre-treatment and post-treatment SUVmax in lymphoid organs on whole-body [18F]F-AraG PET/MR imaging (Cohort 1 and 2).
- Time Frame: Baseline up to 8 days
- Safety Issue:
Estimated Enrollment: 31
Study Start Date: March 7, 2017
Phase: Phase 2
Eligibility:
- Age: minimum 18 Years maximum N/A
- Gender: All
Inclusion Criteria:
- Histologically or cytologically documented cancer to which anti-PD1 or anti-PDL1 are approved therapies
- Eligible for with plan to undergo neoadjuvant treatment with atezolizumab followed by surgery as part of a companion study (NCT02451423), or planned to undergo treatment with anti-PD-1 or anti-PD-L1 per standard of care
- Must have measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 regardless of disease stage (e.g. localized, locally advanced, or metastatic)
- In female patients, negative pregnancy test with no plans to become pregnant during the duration of the study
- Able to provide informed consent and follow the study guidelines
- Archival tumor tissue from biopsy or resection will be required for all patients; archival tissue should be of good quality based on total and viable tumor contents; fine needle aspiration, brushing, and cytologic cell pellets are not acceptable
Exclusion Criteria:
- History of prior treatment with immune checkpoint antibodies (e.g. anti-PD1, anti-PDL1, anti-CTLA4 antibody) or co-stimulatory agonist antibodies (e.g. anti-41BB, anti-OX40) * Prior intravesical treatment with Bacillus Calmette-Guerin (BCG) is allowed; however, the last dose must be at least 6 weeks from time of enrollment and patients must have documented progressive disease at least 6 weeks from completion of last BCG
- Diagnosis of immunodeficiency including history of human immunodeficiency virus (HIV)
- Receiving systemic steroid therapy or any form of immunosuppressive therapy within 7 days prior to first injection of [18F]F-AraG * Topical and inhaled corticosteroids are allowed
- Prior allogeneic stem cell or solid organ transplant
- Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the study
- Biopsy or resection of the primary tumor within 14 days the first injection of [18F]F-AraG
- Contraindication to magnetic resonance (MRI) imaging, as determined through review of the University of California, San Francisco (UCSF) MRI screening form by study investigator
- Evidence of active infection within 14 days of study enrollment
- Female patients who are pregnant or breastfeeding
- Inability to receive furosemide (Lasix) in the opinion of the treating investigator
- Patients that plan to receive off-label use of anti-PD1 or anti-PDL1
