Overall Response Rate (ORR), Central Independent Review Assessed by RECIST v1.1 Primary · From baseline until disease progression, death, lost to follow-up or withdrawal of consent, whichever occurs first, assessed up to approximately 50 months from treatment initiation

Overall Response Rate (ORR) was defined as the proportion of participants with best overall response (BOR) of complete response (CR) or partial response (PR), as per central independent review assessment and according to RECIST 1.1.

Progression Free Survival (PFS), Investigator Assessed by RECIST v1.1 Secondary · From baseline until disease progression or death due to any cause, whichever occurs first, assessed up to approximately 50 months from treatment initiation

Progression Free Survival (PFS) was defined as the time from the date of first dose to the date of the first documented progression or death due to any cause. PFS was assessed via local review according to RECIST 1.1. PFS was censored if no PFS event was observed before the first to occur between: (i) the analysis cut-off date, and (ii) the date when a new anti-neoplastic therapy is started. The censoring date was the date of the last adequate tumor assessment prior to cut-off/start of new anti-neoplastic therapy.

Duration of Response (DoR), Investigator Assessed by RECIST v1.1 Secondary · From first documented response until first documented progression or death due to any cause, whichever occurs first, assessed up to approximately 50 months from treatment initiation

Duration of Response (DoR) only applies to participants whose Best Overall Response (BOR) was complete response (CR) or partial response (PR) according to RECIST 1.1 based on tumor response data per local review. The start date is the date of first documented response of CR or PR (i.e. the start date of response, not the date when response was confirmed), and the end date is defined as the date of the first documented progression or death due to any cause. Participants continuing without progression or death were censored at the date of their last adequate tumor assessment.

Overall Survival (OS) Secondary · From baseline until death due to any cause, assessed up to approximately 50 months from treatment initiation

Overall Survival (OS) was defined as the time from date of first dose to date of death due to any cause. If a participant was not known to have died, then OS was censored at the latest date the participant was known to be alive (on or before the cut-off date).

Mean Change From Baseline in the European Quality of Life (EuroQol)- 5 Dimensions, 5 Level Questionnaire (EQ-5D-5L) Secondary · Baseline (BL), Week 12, End of Treatment (up to approximately 50 months after treatment initiation)

The EQ-5D-5L is a standardized tool for measuring health-related quality of life (HRQoL). The instrument includes a descriptive system and a visual analogue scale. The descriptive system covers five dimensions (Mobility, Self-care, Usual activities, Pain/discomfort, Anxiety/depression), each with five severity levels ranging from 0 (no problems) to 5 (extreme problems) resulting in a 5-digit health code. In China, a country-specific value set is used to convert the five-digit health state into a utility score, ranging from \<0 (worse than death) to 1.0 (perfect health). A positive change from

The EORTC QLQ-C30 is a 30-item questionnaire that patients complete, consisting of both multi-item scales and single-item measures. It includes five functional scales, three symptom scales, six single items, and a Global Health Status/Quality of Life (GHS/QoL) scale. The GHS/QoL scale has seven possible response scores ranging from 1 (very poor) to 7 (excellent), which are averaged and transformed to a 0-100 scale. A higher score on this scale indicates a better quality of life. The change from baseline in GHS/QoL scores is calculated. A positive change from baseline indicated improvement in t

Percentage of Participants With Adverse Events (AEs) Secondary · From baseline until end of study, assessed up to approximately 50 months

An adverse event (AE) is any untoward medical occurrence (e.g. any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a participant or clinical investigation participant after providing written informed consent for participation in the study. Therefore, an AE may or may not be temporally or causally associated with the use of a medicinal (investigational) product. Treatment Emergent Adverse Events (TEAEs) in this study are events that started after the first dose of study treatment and until 30 days after last dose.

Sponsor's own description

This was a single-arm, open label, multicenter phase II, study of dabrafenib in combination with trametinib in Chinese participants with BRAF V600E mutation positive, stage IV NSCLC (American joint committee on cancer staging 8th edition). Approximately 40 Chinese adults were to be enrolled in this study. Participants were to be treated with dabrafenib in combination with trametinib until disease progression, start of a new anti-neoplastic therapy, unacceptable toxicity, pregnancy, withdrawal of consent, lost to follow-up, physician's decision, death, or if study be terminated by the sponsor. The general study design was discussed and agreed with China National Medical Products Administration and was based on a similar design used in the global pivotal phase II study (Study 113928 / NCT01336634).
