En studie av Atezolizumab Plus Tiragolumab i kombinasjon med paklitaksel og cisplatin sammenlignet med paklitaksel og cisplatin som førstelinjebehandling hos deltakere med uoperabelt lokalt avansert, uoperabelt tilbakevendende eller metastatisk esophageal karsinom (SKYSCRAPER-08)

4. august 2026 oppdatert av: Hoffmann-La Roche

En fase III, randomisert, dobbeltblind, placebokontrollert studie av Atezolizumab Plus Tiragolumab i kombinasjon med paklitaksel og cisplatin sammenlignet med paklitaksel og cisplatin som førstelinjebehandling hos pasienter med uoperabelt lokalt avansert, uoperabelt tilbakevendende eller metastatisk squamsofag i karcinomer.

Hensikten med denne studien er å evaluere effektiviteten og sikkerheten til atezolizumab pluss tiragolumab i kombinasjon med paklitaksel og cisplatin (PC) sammenlignet med atezolizumab matchende placebo pluss tiragolumab matchende placebo pluss PC som førstelinjebehandling hos deltakere med uoperabelt lokalt avansert, uoperabelt tilbakevendende , eller metastatisk esophageal carcinoma (EC). Deltakerne vil bli randomisert i forholdet 1:1 for å motta ett av følgende behandlingsregimer under induksjonsfasen:

Arm A: Atezolizumab pluss Tiragolumab og PC Arm B: Atezolizumab placebo pluss Tiragolumab placebo og PC Etter induksjonsfasen vil deltakerne fortsette vedlikeholdsbehandlingen med enten atezolizumab pluss tiragolumab (arm A) eller atezolizumab-matchende placebo pluss tiragolumab-matchende placebo (arm B).

Tidsramme
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). PD was defined as at least a 20% increase in the sum of diameters (SOD) of target lesions, taking as reference the smallest SOD at prior timepoints (including baseline).

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.

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.

Number of Participants With Anti-drug Antibodies (ADAs) to Tiragolumab
Tidsramme: 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.
