En undersøgelse af atezolizumab versus placebo som adjuverende terapi hos patienter med højrisiko muskelinvasiv blærekræft, som er ctDNA-positive efter cystektomi (IMvigor011)
En fase III, dobbeltblind, multicenter, randomiseret undersøgelse af Atezolizumab (Anti-PDL1 antistof) versus placebo som adjuverende terapi hos patienter med højrisiko muskelinvasiv blærekræft, som er ctDNA-positive efter cystektomi
This is a global Phase III, randomized, placebo-controlled, double-blind study designed to evaluate the efficacy and safety of adjuvant treatment with atezolizumab compared with placebo in participants with MIBC who are circulating tumour deoxyribonucleic acid (ctDNA) positive and are at high risk for recurrence following cystectomy.

Eksperimentel: Arm A: Atezolizumab
Atezolizumab will be administered intravenously (IV) at a dose of 1680 milligrams (mg) on Day 1 of each 28-day cycle for 12 cycles or up to 1 year (whichever occurs first). Atezolizumab will be discontinued in the event of disease recurrence, unacceptable toxicity, withdrawal of consent, or study termination by the Sponsor. |
ctDNA positive participants will receive 1680 mg IV, every 4 weeks (Q4W) on Day 1 of each 28-day cycle.
Andre navne:
Signatera will be used to evaluate whether ctDNA is detected during serial monitoring of peripheral blood samples for participants enrolled in surveillance. Participants with a ctDNA positive result will be screened for inclusion in the treatment phase. Participants who remain ctDNA negative at 12 months from the date of cystectomy will not be randomized to treatment and will enter surveillance follow-up. |
|
Placebo komparator: Arm B: Placebo
Placebo will be administered IV on Day 1 of each 28-day cycle. Placebo will be discontinued in the event of disease recurrence, unacceptable toxicity, withdrawal of consent, or study termination by the Sponsor. Following the primary analysis, participants randomized to the comparator arm might discontinue placebo and may receive treatment outside the study at the investigator's discretion. |

INV-assessed Disease-free Survival (DFS)
Tidsramme: From randomization to the first occurrence of a DFS event (Up to 48.2 months)
|
INV-assessed DFS was defined as the time from randomization to the first occurrence of a DFS event, defined as any of the following: local (pelvic) recurrence of urothelial carcinoma (UC) (including soft tissue and regional lymph nodes); urinary tract recurrence of UC (including all pathological stages and grades); distant metastasis of UC; or death from any cause. Participants without an INV-assessed DFS event were censored at the last date the participant was assessed to be alive and recurrence-free as determined with radiographic evidence. Kaplan-Meier (KM) methodology was used to estimate the median DFS. |

Overall Survival (OS)
Tidsramme: From randomization to death from any cause (Up to 48.2 months)
|
OS was defined as the time from randomization to death from any cause. Data for participants who did not die at the time of analysis were censored at the date last known to be alive. Data for participants who did not have post-baseline information were censored at the date of randomization. KM methodology was used to estimate the median OS. |

Independent Review Facility (IRF)-Assessed DFS
Tidsramme: From randomization to the first occurrence of a DFS event (Up to 48.2 months)
|
IRF-assessed DFS was defined as the time from randomization to the first occurrence of a DFS event, defined as any of the following: local (pelvic) recurrence of UC (including soft tissue and regional lymph nodes); urinary tract recurrence of UC (including all pathological stages and grades); distant metastasis of UC; or death from any cause. Participants without an IRF-assessed DFS event were censored at the last date the participant was assessed to be alive and recurrence-free as determined with radiographic evidence. KM methodology was used to estimate the median DFS. |

INV-assessed Disease-specific Survival (DSS)
Tidsramme: From randomization to death from UC (Up to 48.2 months)
|
INV-assessed DSS was defined as the time from randomization to death from UC per investigator assessment of cause of death. Data for participants who did not die will be censored at the last date they were known to be alive. Data for participants who died from causes other than bladder cancer were censored at the date of death. KM methodology was used to estimate the median DSS. |
From randomization to death from UC (Up to 48.2 months)
|
|
INV-assessed Distant Metastasis-free Survival (DMFS)
Tidsramme: From randomization to the first occurrence of a DMFS event (Up to 48.2 months)
|
INV-assessed DMFS was defined as the time from randomization to the first occurrence of a DMFS event, defined as diagnosis of distant (i.e., non-locoregional) metastasis or death from any cause. Data for participants without a DMFS event were censored at the last date the participant was assessed to be alive and free of distant metastasis. Data for participants with no post-baseline disease assessment were censored at the randomization date. KM methodology was used to estimate the median DMFS. |

Time to Confirmed Deterioration (TTCD) in Physical Functioning, Role Functioning & Global Health Status/Quality of Life (GHS/QoL), Assessed by European Organisation for Research & Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30)
Tidsramme: Up to 11.8 months
|
TTCD of physical functioning (PF), role functioning (RF) & health-related quality of life (HRQoL) was defined as time from randomization to first documented confirmed deterioration. Confirmed deterioration=participant's first ≥10-point score decrease from baseline on EORTC QLQ C30 PF, RF or GHS/QoL scale that must be held for ≤2 consecutive time points or followed by death due to cancer progression within 8 weeks from last patient-reported outcomes (PRO) assessment. EORTC QLQ-C30 has 30 questions assessing 5 aspects of participant functioning (physical, emotional, role, cognitive & social), 3 symptom scales (fatigue, nausea & vomiting & pain), GHS/QoL & 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea & financial difficulties). Functioning items are scored on a 4-point scale (1=Not at All to 4=Very Much) & GHS/QoL on a 7-point scale (1=very poor to 7=excellent). Scores are linearly transformed on a scale of 0 to 100. High score=better functioning/better QoL. |
Up to 11.8 months

|
Percentage of Participants With ctDNA Clearance
Tidsramme: Baseline, Day 1 of Cycles 3 or 5 (Cycle length = 28 days)
|
ctDNA clearance was defined as the percentage of participants who were ctDNA positive at baseline and ctDNA negative at Cycle 3, Day 1 or Cycle 5, Day 1. Percentages have been rounded off. |
Baseline, Day 1 of Cycles 3 or 5 (Cycle length = 28 days)

AE is defined as any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. |
From initiation of study treatment up to approximately 5 years

Number of Participants With Anti-drug Antibodies (ADAs) to Atezolizumab
Tidsramme: Up to 12.8 months

Participants who received atezolizumab were considered to be treatment-emergent ADA-positive if they were ADA-negative or had missing data at baseline but developed an ADA response following atezolizumab exposure (treatment-induced ADA response), or if they were ADA-positive at baseline and the titer of one or more post-baseline samples was at least 0.60 titer units (t.u.) greater than the titer of the baseline sample (treatment-enhanced ADA response). Participants with a positive post-baseline sample have been reported here. |
