Brief summary: This is a phase II randomized study of standard of care (SOC) neo-adjuvant cisplatin chemotherapy (NAC) versus NAC plus durvalumab in patients with either clinical or pathologic intra-pelvic node-positive urothelial carcinoma of the bladder. Patients with cTanyN1-3M0 via American Joint Committee on Cancer (AJCC) 8th edition staging30 will be considered tor enrollment in this trial. We plan to enroll 60 patients. Patients will be randomized 2:1 to the intervention arm with durvalumab plus NAC vs SOC NAC. In patients randomized to receive, durvalumab will be continued as maintenance every 4 weeks until either relapse or 1 year, whichever event occurs first.

Tissue collection will occur as a biopsy prior to initiation of neo-adjuvant therapy via both transurethral biopsy of bladder and lymph node biopsy. Tissue will again be collected at the time of radical cystectomy or, in patients who are no longer surgical candidates, in the form of biopsy as standard of care. Blood and urine will be collected at baseline, week 2, week 6, week 16, and at the 6 week-post surgery visit for analysis of correlative studies.

Detailed description: Primary Objective:

• To estimate the difference in pathologic complete response rate as defined as no evidence of disease (ypT0N0) or carcinoma in situ within the bladder only (ypTcisN0) in patients after administration of the combination of dose-dense MVAC and durvalumab versus dose-dense MVAC alone.

Secondary Objectives:

* To estimate the difference in the rate of patients eligible for surgical consolidation within 90 days of completion of pre-surgical treatment.
* To estimate the difference in the proportion of patients with relapse free survival at 12 and 36 months following surgery in each treatment arm.
* To estimate the difference in overall survival for both arms on study.
* To measure lymph node response with those with measurable disease via RECIST v1.1 criteria at baseline, week 6, and week 12 on study.
* To evaluate the toxicity of the combination of dose-dense MVAC chemotherapy and durvalumab.

Correlative Objectives:

• Exploratory biomarkers to study the correlation between immunological and molecular changes in tumor tissues and peripheral blood with pathologic complete response, time until relapse and rate of adverse events, with a specific emphasis upon comparison of tissue samples in patients exposed to combination dose-dense MVAC and durvalumab versus dose-dense MVAC alone

  * Renal iv. Creatinine clearance \> 50 ml/min as calculated by the Cockgroft Gault formula as:

    1. CLCR = {\[(140-age) × weight)\]/(72 x SCR) × 0.85 (if female), where CLCR (creatinine clearance) is measured in mL/min, age is expressed in years, weight in kilograms (kg), and SCR (serum creatinine) in mg/dL.
  * Hepatic v. Serum total bilirubin ≤1.5xULN OR Direct bilirubin ≤ULN for subjects with total bilirubin levels \>1.5xULN. vi. AST and ALT ≤2.5xULN OR ≤5xULN for subjects with liver metastases.
  * Coagulation vii. International Normalized Ratio (INR) or Prothrombin Time (PT) ≤1.5xULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants. viii. Activated Partial Thromboplastin Time (aPTT) ≤1.5xULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants.
* Women of child-bearing potential MUST have a negative serum or urine HCG test unless prior tubal ligation (\>/= 1 year before screening), total hysterectomy or menopause (defined as 12 consecutive months of amenorrhea). Patients should not become pregnant or breastfeed while on this study. Sexually active patients must agree to use dual contraception for the duration of study participation and for 90 days after receipt of last drug on active treatment.
* Ability to understand and willingness to sign informed consent from prior to initiation of the study and any study procedures.
* Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.

Exclusion Criteria:

* Has metastatic disease to lymph nodes outside of the pelvis or to visceral sites as seen on imaging.
* CTCAE v5.0 Grade ≥ 2 neuropathy.
* CTCAE v5.0 Grade ≥ 2 hearing loss.
* New York Heart Association (NYHA) Class III or IV heart failure defined as:

  * Class III heart failure is defined as: patients with cardiac disease resulting in marked limitation of physical activity and/or less than ordinary activity causes fatigue. Patients are comfortable only at rest.
  * Unable to carry on any physical activity without discomfort. Symptoms of heart failure at rest. If any physical activity is undertaken, discomfort increases
* Known active Hepatitis B, Hepatitis C infection (HCV-DNA positive), or HIV infection.
* Current or prior use of immunosuppressive medication within 28 days before the first dose of study drug, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid. Systemic steroid administration required to manage toxicities arising from chemotherapy and/or immunotherapy delivered as part of the therapy on trial is allowed.
* Prior exposure to any anti-PD-1 or anti-PD-L1 (including durvalumab) antibody.
* Active or prior documented autoimmune disease within the past 2 years. NOTE: Patients with vitiligo, Grave's disease, or psoriasis not requiring systemic treatment (within the past 2 years) are not excluded.

* Established use of oral, inserted, or injected or implanted hormonal methods of contraception are allowed provided the patient remains on the same treatment throughout the entire study and has been using that hormonal contraceptive for an adequate period of time to ensure effectiveness.
