Gene therapy joins forces with chemo and immunotherapy to fight bladder cancer

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥ 18 years at the time of screening * Ability to understand and willingness to sign the written informed consent document * Patients with confirmed muscle-invasive urothelial carcinoma of the bladder (cT2-4a, N0-1, M0 or cT1, N1, M0), who are planning to undergo RC * Pure urothelial or mixed histologic subtypes are allowed if urothelial is the primary histology (regardless of the % of conventional urothelial histology) * Eligible to receive neoadjuvant cisplatin/gemcitabine and durvalumab per the patient's medical oncologist's discretion * Eastern Cooperative Oncology Group (ECOG) performance status 0-1 * Hemoglobin count ≥ 9 gm/dL * Absolute neutrophil count of ≥ 1500 cells/uL * Platelet count of ≥ 100,000/uL * Alanine and aspartate aminotransferase levels ≤ 2.5 x upper limit of normal (ULN) * Total bilirubin ≤ 1.5 x ULN (≤ 2.5 x ULN for Gilbert syndrome) * Creatinine clearance or estimated glomerular filtration rate (GFR) ≥ 40ml/min (using Chronic Kidney Disease Epidemiology Collaboration Formula \[CKD-EPI\] 2021 equation) * For patients with evidence of, or history of HIV, chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, the viral load must be undetectable, or the infection must have been treated and cured. Patients are not allowed to be on immunosuppressive agents for HIV, HBV or HCV. Routine testing for HIV, HBV and HCV is not required for patients without such history unless clinically indicated * Individuals with a prior malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are allowed to enroll Exclusion Criteria: * cT4b, N2-3, or M1 stage at time of screening * Any known concurrent clinically relevant malignancies * Prior systemic therapy for muscle-invasive bladder carcinoma (MIBC) (prior intravenous pembrolizumab for non-muscle invasive bladder carcinoma \[NMIBC\] is allowed) * Current or prior use of systemic immunosuppressive medication within 14 days before first dose of investigational product. The following are allowed (not systemic route): intranasal, inhaled, intra-articular, topical steroids, local steroid injections * Pure non-urothelial histology subtype/variant or any neuroendocrine (small or large cell) component * Prior treatment with adenovirus-based drugs * Known hypersensitivity or allergy to any components of rAd-interferon (IFN)a/Syn3 * Currently receiving other investigational agent * Pregnant or lactating women
