ADAPT-BLADDER: Modern Immunotherapy in BCG-Relapsing Urothelial Carcinoma of the Bladder
Trial ID or NCT#
A multi-arm multi-stage (MAMS) phase 1/2 study. Phase 1 will be conducted in BCG-unresponsive NMIBC patients to establish the safety of durvalumab monotherapy (cohort 1) and durvalumab in combination with BCG (cohort 2a) and external beam radiation therapy (EBRT) (cohort 2b). Provided safety is demonstrated and recommended phase 2 doses (RP2D) are established in phase 1, the study will proceed to phase 2 testing. Phase 2 will be conducted in the BCG-relapsing or persistent NMIBC population. In phase 2, BCG-relapsing or persistent NMIBC subjects will be randomized between treatment arms examining intravesical BCG in combination with novel immunotherapy agents (durvalumab), novel immunotherapy in combination with radiation (durvalumab + EBRT), or retreatment with intravesical BCG. In addition to providing additional safety data on the combination regimens studied, phase 2 will provide preliminary efficacy profiles for BCG-relapsing or persistent NMIBC subjects with and without CIS treated with each regimen. For regimens demonstrating a tolerable safety profile and encouraging clinical activity in this phase 1/2 design, a randomized phase 3 trial of experimental arm therapy versus re-treatment with intravesical BCG therapy would be considered.

Subjects that have completed all necessary therapy and are considered to be at less than 30% risk of relapse are not considered to have an active second malignancy and are eligible for enrollment. - Subjects who have received the last administration of an anti-cancer therapy including chemotherapy, immunotherapy, and monoclonal antibodies ≤ 4 weeks prior to starting study drug, or who have not recovered from the side effects of such therapy. - Any unresolved toxicity NCI CTCAE Grade ≥ 2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria: - Patients with Grade ≥ 2 neuropathy will be evaluated on a case-by-case basis after consultation with the sponsor-investigator. - Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the sponsor-investigator. - Subjects who have received prior therapy with PD-1 or PD-L1 directed agents. - Subjects who have had any prior radiation to the prostate or pelvis. - Subjects who have undergone major surgery (e.g. intra-thoracic, intra-abdominal or intra-pelvic), open biopsy or significant traumatic injury ≤ 4 weeks prior to starting study drug, or subjects who have had minor procedures (i.e. TURBT), percutaneous biopsies or placement of vascular access device ≤ 1 week prior to starting study drug, or who have not recovered from side effects of such procedure or injury. - Subjects with any of the following concurrent severe and/or uncontrolled medical conditions which could compromise participation in the study: - Clinically significant cardiac diseases, including any of the following: - History or presence of serious uncontrolled ventricular arrhythmias. - Clinically significant resting bradycardia. - Any of the following within 3 months prior to starting study drug: myocardial infarction (MI), severe/unstable angina, Coronary Artery Bypass Graft (CABG), Congestive Heart Failure (CHF), Cerebrovascular Accident (CVA), Transient Ischemic Attack (TIA), Pulmonary Embolism (PE). - Uncontrolled hypertension defined by a SBP ≥ 160 mm Hg and/or DBP ≥ 100 mm Hg, with or without anti-hypertensive medication(s). - Cirrhosis - Active Infection (includes chronic active and chronic persistent). - Tuberculosis - Hepatitis B (known positive HBV surface antigen (HbsAg). Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody [anti-HBc] and absence of HbsAg) are eligible. - Hepatitis C. Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA. - Known diagnosis of human immunodeficiency virus (HIV/positive HIV 1/2 antibodies) infection (HIV testing is not mandatory). - Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., colitis or Crohn's disease], diverticulitis [with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.]). The following are exceptions to this criterion: - Patients with vitiligo or alopecia. - Patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement. - Any chronic skin condition that does not require systemic therapy. - Patients without active disease in the last 5 years may be included but only after consultation with the study physician. - Patients with celiac disease controlled by diet alone. - Other concurrent severe and/or uncontrolled concomitant medical conditions (e.g. active or uncontrolled infection, uncontrolled diabetes) that could cause unacceptable safety risks or compromise compliance with the protocol. - Current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab. The following are exceptions to this criterion: - Intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection). - Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent. - Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication). - Usage of non-steroidal anti-inflammatory medications (NSAIDS) for the treatment of osteoarthritis and uric acid synthesis inhibitors for the treatment of gout are permitted. - Pregnant or breast-feeding women. Women of child-bearing potential must have a negative urine or serum test ≤ 14 days prior to starting study drug. - Women of child-bearing potential, who are biologically able to conceive, and not employing two forms of highly effective contraception or abstinence. Highly effective contraception or abstinence must be used from the time of informed consent, throughout the trial and up to 180 days after the last dose of durvalumab (e.g. male condom with spermicidal; diaphragm with spermicide; intra-uterine device). 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-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy). - Women ≥50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses >1 year ago, had chemotherapy-induced menopause with last menses >1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy). - Fertile males not willing to use contraception or abstinence, as stated above. Contraception or abstinence must be followed from screening through 180 days after receipt of the final dose of durvalumab therapy. - Subjects unwilling or unable to comply with the protocol. - Receipt of live attenuated vaccine within 30 days prior to the first dose of IP. - Known allergy or hypersensitivity to any of the study drugs or any of the study drug excipients.
