Primary Outcome Measures :
  1. The efficacy of Durvalumab+Olaparib combination therapy compared to Durvalumab + Placebo in terms of Progression-Free Survival (PFS) in patients with Platinum ineligible bladder cancer [ Time Frame: 2 years ]

Secondary Outcome Measures :
  1. The efficacy of Durvalumab+Olaparib combination therapy compared to Durvalumab + Placebo in terms of Overall survival (OS) in patients with Platinum ineligible bladder cancer [ Time Frame: 4 years ]
  2. The efficacy of Durvalumab+Olaparib combination therapy compared to Durvalumab + Placebo in terms of Duration of response (DoR) in patients with Platinum ineligible bladder cancer [ Time Frame: 2 years ]
  3. The efficacy of Durvalumab+Olaparib combination therapy compared to Durvalumab + Placebo in terms of Objective Response Rate (ORR) in patients with Platinum ineligible bladder cancer [ Time Frame: 2 years ]
  4. The efficacy of Durvalumab+Olaparib combination therapy compared to Durvalumab + Placebo in terms of Progression-Free Survival (PFS) in patients with Platinum ineligible bladder cancer with homologous recombination repair mutated (HRRm) subgroup [ Time Frame: 2 years ]
  5. The efficacy of Durvalumab+Olaparib combination therapy compared to Durvalumab + Placebo in terms of Progression free at 6 months (PFS6) in patients with Platinum ineligible bladder cancer [ Time Frame: 2 years. ]
  6. The pharmacokinetics (PK) of durvalumab and olaparib as determined by trough concentration [ Time Frame: Concentration of durvalumab and olaparib will be assessed three times, in Cycle 1 (each cycle is 28 days), 2 and 4. Additional assessments at Day 30 post last dose for olaparib, 3 months post last dose for durvalumab. ]
  7. Presence of anti-drug antibodies (ADA) for durvalumab [ Time Frame: ADA for durvalumab will be assessed three times, in Cycle 1(each cycle is 28 days), 2 and 4, and 3 and 6 months post last dose of durvalumab. ]
  8. Patient reported outcome (PRO) including Global health status/Quality of Life (QoL), assessed through questionnaire - European Organisation for Research and Treatment of Cancer 30-item core quality of life questionnaire (EORTC QLQ-C30) [ Time Frame: PRO:Global health status assessment on day of first dose and every 4 weeks until 3 months post treatment discontinuation. ]

Other Outcome Measures:
  1. Number of Participants with Treatment-Related Adverse Events as Assessed by Common Terminology Criteria for Adverse Events (CTCAE) [ Time Frame: 2 years ]
  2. Changes in WHO/ECOG performance status [ Time Frame: 2 years ]
