Inclusion Criteria (Phase 1 Only): - In addition to the inclusion criteria required of all patients listed above, the following inclusion criteria are also required of patients enrolling to Phase 1 of the study. - BCG-unresponsive disease defined by any of the following: - Persistent or recurrent CIS with or without the presence of concurrent Ta or T1 tumors within 12 months of completion of adequate BCG therapy - Recurrent high-grade Ta or T1 tumors within 6 months of completion of adequate BCG therapy NOTE: In recognition of the fact that procedure scheduling factors beyond the control of the patient or treating physician may cause unintended delays in disease evaluations, patients with pure papillary tumors (Ta or T1) with no components of CIS with recurrence documented within 9 months of completion of adequate BCG therapy who meet all other eligibility criteria may be considered for enrollment after consultation with the study chair. - Persistent T1 high-grade tumors at the first disease evaluation (e.g. 3- month post-treatment evaluation) following an adequate BCG induction course - Prostatic urethra involvement of NMIBC Adequate BCG therapy is defined as at least one of the following: - At least 5 of 6 doses of an initial induction BCG course plus at least 2 of 3 doses of maintenance therapy - At least 5 of 6 doses of an initial induction BCG course plus at least 2 of 6 doses of a second induction course NOTE: Patients with concurrent non-muscle invasive tumors (CIS, Ta, T1) in the prostatic urethra and/or concurrent non-invasive tumors (CIS, Ta) in the upper urinary tracts (ureter, renal pelvis) are permitted to enroll in Phase 1 of the study. Patients with concurrent T1 tumors in the upper urinary tracts (ureter, renal pelvis) are not eligible to enroll in Phase 1 of the study. Patients who have met the BCG-unresponsive criteria at any time point in their treatment history are permitted to enroll in Phase 1 of the study regardless of the time frame between their most recent BCG treatment administration and study registration dates. Inclusion Criteria (Phase 2 Only): - In addition to the inclusion criteria required of all patients listed above, the following inclusion criteria are also required of patients enrolling to Phase 2 of the study. Intermediate or high-risk NMIBC defined according to modified EORTC risk criteria summarized as follows: - Low-risk Tumors Initial or recurrent tumor > 12 months after resection with all of the following: - Solitary tumor - Low-grade - < 3 cm - No CIS - Intermediate-Risk Tumors: All tumors not defined in the two adjacent categories (between the category of low- and high-risk). - High-risk Tumors: Any of the following: - T1 tumor - High-grade - CIS - Multiple and recurrent and large (> 3 cm) Ta low-grade tumors (all conditions must be met for this point on Ta low-grade tumors). - Documented recurrence within 15 months of last exposure to intravesical therapy. - Recurrence after 1 prior induction course of intravesical BCG. 8. BCG-relapsing NMIBC defined as recurrent intermediate- or high-risk NMIBC after achievement of a complete response to initial BCG induction therapy which does not meet any of the BCG-unresponsive criteria outlined in section 3.1.2. OR BCG-persistent NMIBC defined as persistent intermediate- or high-risk NMIBC at the first disease evaluation after initial BCG induction therapy (with no intervening achievement of complete response) for which a second course of BCG induction therapy is considered a standard of care (e.g. CIS or high grade Ta tumors) which does not meet any of the BCG-unresponsive criteria outlined in section 3.1.2. NOTE: Patients who have received additional non-BCG based intravesical therapies (e.g. chemotherapy, non-BCG investigational agents) are eligible provided they have received only 1 prior course of BCG induction therapy and satisfy the above BCG-relapsing or BCG-persistent definitions.

Women of child-bearing potential are defined as sexually mature women who have not undergone a hysterectomy or who have not been naturally postmenopausal for at least 12 consecutive months (i.e., who has had menses any time in the preceding 12 consecutive months). Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply: - Women <50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menop
Patient Assignment in Phase 1 Prior to commencing accrual, each study site will be required to self-identify their site as a site with (EBRT+) or without (EBRT-) the capacity to provide radiation therapy as specified in the durvalumab + EBRT arm. The radiation therapy status of each site will remain fixed throughout the course of the trial. In phase 1 of the protocol, patients will be assigned to study treatment cohorts based on patient slot availability and study site choice of radiation therapy arm participation. Patient Randomization in Phase 2 In phase 2 of the protocol, subjects registered at self-identified EBRT+ study sites will be randomized 1:1 between all actively accruing study arms while subjects registered at self-identified EBRT- study sites will be randomized 1:1 between all actively accruing study arms except the durvalumab + EBRT arm. Papillary Subgroup Enrollment Cap As described further in the Section 12 enrollment in Phase 2 of patients with papillary only (Ta or T1) tumors with no evidence of concurrent CIS within each experimental study arm will be capped to ensure adequate representation of patients with CIS for planned efficacy analyses.
