Trial Outcomes & Findings for Dacomitinib for Treatment of Patients in India With Metastatic Non Small Cell Lung Cancer With EGFR Activating Mutations (NCT NCT04511533)

NCT ID: NCT04511533

Last Updated: 2024-04-05

Results Overview

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Relatedness to study drug was assessed by the investigator. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to approximately 107.3 weeks that were absent before treatment or that worsened relative to pretreatment state.

PRIMARY outcome

Timeframe: From the first dose of study treatment up to 28 days after the last dose of study treatment (maximum treatment duration: 107.3 weeks)

Population: All participants who received at least 1 dose of dacomitinib.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Relatedness to study drug was assessed by the investigator. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to approximately 107.3 weeks that were absent before treatment or that worsened relative to pretreatment state.

SECONDARY outcome

Timeframe: From time of first dose until disease progression, death or initiation of a new anticancer therapy, whichever occurs first, assessed for up to 26 months

Population: All participants who received at least 1 dose of dacomitinib.

Percentage of participants with objective response based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to RECIST. Confirmed responses are those that persist on repeat imaging study at least 4 weeks after initial documentation of response. Per RECIST v1.1: CR was defined as complete disappearance of all target lesions and non-target disease, with the exception of nodal disease. All nodes, both target and non-target, must decrease to normal (short axis \<10 mm). No new lesions. PR was defined as \>=30% decrease under baseline of the sum of diameters of all target lesions. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. No unequivocal progression of non-target disease. No new lesions. Stable disease was defined as not qualifying for CR, PR, Progressive Disease.

SECONDARY outcome

Timeframe: From time of first tumor response until disease progression, death or initiation of a new anticancer therapy, whichever occurs first, assessed for up to 26 months

Population: All participants who received at least 1 dose of dacomitinib. DOR was only for the subset participants with an objective response.

DOR: time from first documented occurrence of response (PR or CR) until date of first documented PD or death due to underlying cancer. RECIST 1.1. CR: disappearance of all non-nodal target lesions and of all non-target lesions. In addition, any pathological lymph nodes assigned as target lesions/ non-target lesions must have a reduction in short axis to \<10 mm. PR: at least a 30% decrease in sum of diameter of all target lesions, taking as reference baseline sum of diameters. PD: at least a 20% increase in sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline. In addition to the relative increase of 20%, sum must also demonstrate an absolute increase of at least 5 mm\^2. Unequivocal progression of existing non-target lesions. Appearance of new lesions. Participants with no PD and were still alive, were censored at last adequate tumor assessment. Kaplan-Meier method was used for DOR analysis.
