Um estudo de atezolizumabe mais tiragolumabe em combinação com paclitaxel e cisplatina em comparação com paclitaxel e cisplatina como tratamento de primeira linha em participantes com carcinoma esofágico localmente avançado irressecável, recorrente irressecável ou metastático (SKYSCRAPER-08)

4 de agosto de 2026 atualizado por: Hoffmann-La Roche

Um estudo de fase III, randomizado, duplo-cego, controlado por placebo de atezolizumabe mais tiragolumabe em combinação com paclitaxel e cisplatina comparado com paclitaxel e cisplatina como tratamento de primeira linha em pacientes com carcinoma de células escamosas de esôfago irressecável localmente avançado, irressecável recorrente ou metastático

O objetivo deste estudo é avaliar a eficácia e segurança de atezolizumabe mais tiragolumabe em combinação com paclitaxel e cisplatina (PC) em comparação com atezolizumabe correspondente placebo mais tiragolumabe correspondente placebo mais PC como tratamento de primeira linha em participantes com localmente avançado irressecável, recorrente irressecável , ou carcinoma esofágico metastático (EC). Os participantes serão randomizados em uma proporção de 1:1 para receber um dos seguintes regimes de tratamento durante a fase de indução:

Braço A: Atezolizumabe mais Tiragolumabe e PC Braço B: Atezolizumabe placebo mais Tiragolumabe placebo e PC Após a fase de indução, os participantes continuarão a terapia de manutenção com atezolizumabe mais tiragolumabe (Grupo A) ou atezolizumabe com placebo mais tiragolumabe com placebo (Grupo B).

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)
Prazo: 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.
Up to approximately 27 months
TTCD in Participant-reported Role Functioning (RF), as Measured by EORTC QLQ-C30
Prazo: Up to approximately 27 months
Clinically meaningful changes in role 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), 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.
Up to approximately 27 months
TTCD in Participant-Reported GHS/QoL, as Measured by EORTC QLQ-C30
Prazo: Up to approximately 27 months
Clinically meaningful changes in GHS/QoL 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), 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.

TTCD in Participant-reported Dysphagia, as Measured by European Organisation for Research and Treatment of Cancer Quality-of-life Esophageal Cancer, Module 18 Questionnaire (EORTC QLQ-OES18)
Prazo: 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.
Up to approximately 27 months
Number of Participants With Adverse Events (AEs)
Prazo: 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
Prazo: 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.
Up to approximately 49.6 months

Number of Participants With Anti-drug Antibodies (ADAs) to Tiragolumab
Prazo: Up to approximately 27.5 months
Participants were considered to be ADA positive if they were ADA negative at baseline but developed an ADA response following tiragolumab administration (treatment-induced ADA response), or if they were ADA positive at baseline and the titer of one or more post-baseline samples was greater than the titer of the baseline sample by a scientifically reasonable margin such as at least 0.60 titer unit (t.u.) greater than the baseline titer result (treatment-enhanced ADA response). Participants with a positive post-baseline sample have been reported here.
