Inclusion Criteria:

1. 18 years old or older
2. Histologic diagnosis of predominantly urothelial carcinoma of the bladder. Focal differentiation allowed other than small cell histology.
3. Stage T2-T3 N0M0 (AJCC-TNM version 6) based on trans-urethral resection of bladder tumor (TURBT), CT or MRI imaging, +/- bimanual examination under anaesthesia.
4. FDG-PET within 6 weeks from the start of treatments, showing no evidence of lymph nodes or metastatic disease.
5. Attempt of complete trans urethral resection of bladder tumour (TURBT) within 56 days (8 weeks) prior to the start of chemoradiotherapy. If TURBT was performed > 8 weeks prior but a recent cystoscopy shows no residual disease, then a repeat TURBT is not necessary.
6. Life expectancy greater than 6 months
7. Eastern Cooperative Oncology Group (ECOG) performance status of 1 or better
8. Another primary cancer is allowed only if treated with curative intent at least 3 years prior to enrolment without evidence of recurrence or if the untreated cancer is clinically indolent (e.g., lower risk prostate cancer).
9. Patients must be considered able to tolerate systemic chemotherapy combined with pelvic intensity-modulated radiation therapy (IMRT) by the joint agreement of the participating radiation oncologist and medical oncologist.
10. Able and willing to give written informed consent.

11. For women of childbearing potential (WOCBP), study participants must use a contraceptive method that is highly effective (with a failure rate of < 1% per year) for at least 5 months after the last dose of study intervention. Men receiving any study drug and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 6 months after the last dose of chemotherapy with cisplatin or nab-paclitaxel.

    The investigator or a designated associate is requested to advise the subject how to achieve an adequate birth control. Adequate contraception is defined in the study as any medically recommend method (or combination of methods) as per standard of care. Acceptable methods are oral contraceptives, hormonal implants, hormonal patches, IDU, Diaphragm with spermicides, cervical cape with spermicide, and condom with spermicide.

12. Adequate bone-marrow, liver, and renal function as assessed by the following laboratory requirements conducted within 7 days of starting the study treatment:
13. Total bilirubin ≤1∙5 × the upper limit of normal (ULN).
14. Alanine aminotransferase and aspartate aminotransferase ≤2 × ULN (≤5 × ULN for patients with liver involvement of their cancer).
15. International normalized ratio (INR) and partial thromboplastin time (PTT) ≤1∙5 × ULN. Subjects who are therapeutically treated with an agent such as warfarin or heparin will be allowed to participate if no prior evidence of an underlying abnormality in coagulation parameters exists. Close monitoring with at least weekly evaluations will be performed until INR and PTT are stable based on a pre-dose measurement as defined by the local standard of care.
16. Platelet count ≥100 000/mm3, haemoglobin >9 g/dl, absolute neutrophil count >1,500/mm3.
17. Alkaline phosphatase limit ≤2∙5 × ULN (≤5 × ULN for patients with liver involvement of their cancer).
18. Creatinine clearance greater than 40 ml/min as evaluated by Cockcroft-Gault formula.

Exclusion Criteria:

1. Prior systemic therapy for other urothelial tumours.
2. Prior RT to the pelvis
3. Treatment with any other investigational agent or participation in another clinical trial with therapeutic intent within 28 days or five half-lives of the drug, whichever is longer, prior to enrolment.

4. Malignancies other than urothelial cancer within 3 years prior to Cycle 1, Day 1:

   1. Patients with localized lower risk prostate cancer (defined as Stage ≤T2b, Gleason score ≤ 7, and PSA at prostate cancer diagnosis ≤ 20 ng/mL [if measured]) treated with radical prostatectomy and without prostate-specific antigen (PSA) recurrence are eligible.
   2. Patients with lower risk prostate cancer (defined as Stage T1/T2a, Gleason score ≤ 7 and PSA ≤ 10 ng/mL) who are treatment-naive and undergoing active surveillance are eligible.
   3. Patients with malignancies of a negligible risk of metastasis or death (e.g., risk of metastasis or death <5% at 5 years) are eligible provided they meet all the following criteria:
   4. Malignancy treated with expected curative intent (such as adequately treated carcinoma in situ of the cervix, basal or squamous cell skin cancer, or ductal carcinoma in situ of the breast treated surgically with curative intent) No evidence of recurrence or metastasis by follow-up imaging and any disease-specific tumor markers.
5. Pre-existing medical conditions precluding treatment (e.g., previous history of immune-related adverse reactions, pneumonitis, colitis, etc.)
6. History of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins
7. History of autoimmune disease, including, but not limited to, myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, vascular thrombosis associated with antiphospholipid syndrome, Wegener's granulomatosis, Sjogren's syndrome, Guillain-Barré syndrome, multiple sclerosis, vasculitis, or glomerulonephritis. Patients with a history of autoimmune-related hypothyroidism on a stable dose of thyroid replacement hormone may be eligible for this study. Patients with controlled Type I diabetes mellitus on a stable dose of insulin regimen may be eligible for this study.
