Conditions

Non-small Cell Lung Cancer (NSCLC)

Brief summary

The purpose of this study is to evaluate sacituzumab tirumotecan versus pemetrexed in combination with carboplatin for the treatment of epidermal growth factor receptor (EGFR)-mutated advanced non-squamous non-small cell lung cancer (NSCLC). Participants in this study have NSCLC that has continued to progress on prior treatment with EGFR tyrosine kinase inhibitors (TKIs). The primary hypotheses of this study are that sacituzumab tirumotecan is better than platinum-based doublet chemotherapy (pemetrexed and carboplatin) in regard to progression-free survival (PFS) and overall survival (OS).

Detailed description

Participants will be randomized 1:1 into two arms: * Sacituzumab tirumotecan * Pemetrexed plus Carboplatin Participants will receive treatment until any of the criteria for discontinuation of study intervention are met.

Design outcomes

Primary

MeasureTime frameDescription
Progression-Free Survival (PFS)Up to approximately 51 monthsProgression-Free Survival is defined as the time from randomization to the first documented disease progression per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) based on blinded independent central review (BICR) or death due to any cause, whichever occurs first. PFS for all randomized participants will be reported.
Overall Survival (OS)Up to approximately 51 monthsOverall survival is defined as the time from randomization to death due to any cause. Overall survival for all randomized participants will be reported.

Secondary

MeasureTime frameDescription
Objective Response Rate (ORR)Up to approximately 51 monthsThe objective response rate (ORR) is defined as a confirmed complete response (CR: disappearance of all target lesions) or partial response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1 as assessed by BICR. The overall response rate for all randomized participants will be reported.
Duration of Response (DOR)Up to approximately 51 monthsFor participants who demonstrate confirmed CR or PR per RECIST 1.1 as assessed by BICR, duration of response is defined as the time from the first documented evidence of CR or PR until disease progression or death due to any cause, whichever occurs first. CR is defined as the disappearance of all target lesions. PR is defined as at least a 30% decrease in the sum of diameters of target lesions.
Change from Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) Global Health Status (Item 29) and Quality of Life (Item 30) Combined ScoreBaseline and up to approximately 6 yearsThe EORTC-QLQ-C30 is a 30-item questionnaire developed to assess the quality of life of cancer patients. Participant responses to the Global Health Status (GHS) question "How would you rate your overall health during the past week?" (Item 29) and the Quality of Life (QoL) question "How would you rate your overall quality of life during the past week?" (Item 30) are scored on a 7-point scale (1=Very Poor to 7=Excellent). Using linear transformation, raw scores are standardized so that scores range from 0 to 100. A higher value indicates a better level of function. The change from baseline in EORTC QLQ-C30 Items 29 and 30 combined score will be reported.
Change From Baseline in the Dyspnea (Item 8) Score, on the EORTC QLQ-C30Baseline and up to approximately 6 yearsThe EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire. Participant responses to the question "Were you short of breath?" are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized so that scores range from 0 to 100. A higher value indicates increased severity of symptoms. Change from baseline in dyspnea (EORTC QLQ-C30 Item 8) will be reported.
Change from Baseline in the Cough (Item 31) Score, on the EORTC Lung-Cancer specific Quality of Life Questionnaire (QLQ-LC13)Baseline and up to approximately 6 yearsThe EORTC QLQ-LC13 is a lung cancer-specific supplemental questionnaire used in combination with the EORTC QLQ-C30. Participant responses to the question "How much did you cough?" are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher value indicates increased severity of symptoms. Change from baseline in cough (EORTC QLQ-LC13 Item 31) will be reported.
Change from Baseline in the Chest Pain (Item 40) Score, on the EORTC QLQ-LC13Baseline and up to approximately 6 yearsThe EORTC QLQ-LC13 is a lung cancer-specific supplemental questionnaire used in combination with the EORTC QLQ-C30. Participant responses to the question "Have you had pain in your chest?" are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher value indicates increased severity of symptoms. Change from baseline in chest pain (EORTC QLQ-LC13 Item 40) score will be presented.
Time to Deterioration (TTD) in Global Health Status/Quality of Life (Items 29 and 30) Combined Score, on the EORTC QLQ-C30Baseline and up to approximately 6 yearsEORTC-QLQ-C30 is a 30-item questionnaire developed to assess the QoL of cancer patients. Participant responses to Items 29 and 30 ("How would you rate your overall health during the past week?" and "How would you rate your overall quality of life during the past week?") are scored on a 7-point scale (1=Very Poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. TTD in Global Health Status (GHS)/Quality of Life (QoL) is defined as the time from baseline to the first onset of a ≥10-point decrease from baseline in combined GHS/QoL score.
