En undersøgelse af Atezolizumab Plus Tiragolumab i kombination med paclitaxel og cisplatin sammenlignet med paclitaxel og cisplatin som førstelinjebehandling hos deltagere med uoperabelt lokalt avanceret, uoperabelt tilbagevendende eller metastatisk esophageal carcinom (SKYSCRAPER-08)

4. august 2026 opdateret af: Hoffmann-La Roche

Et fase III, randomiseret, dobbeltblindt, placebokontrolleret studie af Atezolizumab Plus Tiragolumab i kombination med paclitaxel og cisplatin sammenlignet med paclitaxel og cisplatin som førstelinjebehandling hos patienter med uoperabelt, lokalt fremskredent, uoperabelt tilbagevendende eller metastatisk celleøserisk squamsophage

Formålet med denne undersøgelse er at evaluere effektiviteten og sikkerheden af ​​atezolizumab plus tiragolumab i kombination med paclitaxel og cisplatin (PC) sammenlignet med atezolizumab matchende placebo plus tiragolumab matchende placebo plus PC som førstelinjebehandling hos deltagere med uoperabelt lokalt fremskreden, uoperabelt tilbagevendende eller metastatisk esophageal carcinom (EC). Deltagerne vil blive randomiseret i forholdet 1:1 til at modtage en af ​​følgende behandlingsregimer under induktionsfasen:

Arm A: Atezolizumab plus Tiragolumab og PC Arm B: Atezolizumab placebo plus Tiragolumab placebo og PC Efter induktionsfasen vil deltagerne fortsætte vedligeholdelsesbehandlingen med enten atezolizumab plus tiragolumab (arm A) eller atezolizumab-matchende placebo plus tiragolumab-matchende placebo (arm B).

Independent Review Facility (IRF)-Assessed Progression-free Survival (PFS)
Tidsramme: From randomization to the first occurrence of PD or death from any cause, whichever occurred first (up to approximately 19 months)
PFS was defined as the time from randomization to the first occurrence of progressive disease (PD) or death from any cause (whichever occurred first), as determined by an IRF according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1).

Time to Confirmed Deterioration (TTCD) in Participant-reported Physical Functioning, as Measured by European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Core 30 (EORTC QLQ-C30)
Tidsramme: Up to approximately 27 months
Clinically meaningful changes in physical functioning as measured by the EORTC QLQ-C30. EORTC QLQ-C30 is a self-reported measure, consisting of 30 questions that assess 5 aspects of participants functioning (physical, emotional, role, cognitive and social), 3 symptom scales (fatigue, nausea and vomiting, and pain), global health status/quality of life (GHS/QoL), and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea and financial difficulties) within the previous week. Physical functioning was scored on a 4-point scale: 1=Not at all, 2=A little, 3=Quite a bit, 4=Very much. Scores were linearly transformed to a range of 0 to 100, with higher scores (i.e. closer to 100) reflecting better functioning. Participants were considered "Worsened" if their baseline score decreased by ≥10 points. K-M method was used to estimate median TTCD.

EORTC QLQ-C30 is a self-reported measure, consisting of 30 questions that assess 5 aspects of participants functioning (physical, emotional, role, cognitive and social), 3 symptom scales (fatigue, nausea and vomiting, and pain), GHS/QoL, and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea and financial difficulties) within the previous week. Role functioning was scored on a 4-point scale: 1=Not at all, 2=A little, 3=Quite a bit, 4=Very much. Scores were linearly transformed to a range of 0 to 100, with higher scores (i.e. closer to 100) reflecting better functioning. Participants were considered "Worsened" if their baseline score decreased by ≥10 points. K-M method was used to estimate median TTCD.

EORTC QLQ-C30 is a self-reported measure, consisting of 30 questions that assess 5 aspects of participants functioning (physical, emotional, role, cognitive and social), 3 symptom scales (fatigue, nausea and vomiting, and pain), GHS/QoL, and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea and financial difficulties) within the previous week. GHS and QoL items were scored on a 7-point scale, with scores ranging from 1=Very poor to 7=Excellent. Scores were linearly transformed to a range of 0 to 100, with higher scores (i.e. closer to 100) reflecting better GHS/QoL. Participants were considered "Worsened" if their baseline score decreased by ≥10 points. K-M method was used to estimate median TTCD.

Tidsramme: Up to approximately 27 months
Clinically meaningful changes in dysphagia as measured by the EORTC QLQ-OES18. EORTC QLQ-OES18 is a modular supplement to the EORTC QLQ-C30 questionnaire for use in participants with esophageal cancer. EORTC QLQ-OES18 consists of 4 multiple-item scale (dysphagia, eating, reflux, and pain) and 6 single items (trouble swallowing saliva, choked when swallowing, dry mouth, trouble with taste, trouble with coughing, and trouble talking) with a recall period of the previous week. Each symptom item was scored on a 4-point scale: 1=Not at all, 2=A little, 3=Quite a bit, 4=Very much. Scores were linearly transformed to a range of 0 to 100, with higher transformed scores (i.e. closer to 100) reflecting worse symptoms. Participants were considered "Worsened" if their baseline score increased by ≥ 10 points. K-M method was used to estimate median TTCD.

Number of Participants With Adverse Events (AEs)
Tidsramme: Up to approximately 49.6 months
An AE was any untoward medical occurrence in a participant administered a pharmaceutical product, and which does not necessarily have a causal relationship with the treatment. An AE was therefore any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product.
Up to approximately 49.6 months
Number of Participants With Cytokine-release Syndrome (CRS), With Severity Determined by the American Society for Transplantation and Cell Therapy (ASTCT) Consensus Grading Scale
Tidsramme: Up to approximately 49.6 months
CRS was defined as supraphysiologic response following administration of any immune therapy that results in activation/engagement of endogenous or infused T cells and/or other immune effector cells. Symptoms may be progressive, including fever at onset, and may also include hypotension, capillary leak (hypoxia), and end-organ dysfunction. Severity of CRS was determined per ASTCT Consensus Grading Criteria, which categorizes CRS into 5 grades: Grade 1: fever (≥38◦Celsius), with/without constitutional symptoms, in absence of hypotension & hypoxia; Grade 2: fever with hypotension not requiring vasopressors and/or hypoxia requiring low-flow oxygen; Grade 3: fever with hypotension requiring one vasopressor, with/without vasopressin, and/or hypoxia requiring high-flow oxygen; Grade 4: fever accompanied by hypotension requiring multiple vasopressors (excluding vasopressin) and/or hypoxia requiring positive-pressure ventilation; Grade 5: death due to CRS.
