Trial Outcomes & Findings for Study of the Safety and Activity of Lenvatinib (E7080) in Subjects With KIF5B-RET-Positive Adenocarcinoma of the Lung (NCT NCT01877083)

NCT ID: NCT01877083

Last Updated: 2019-08-13

Results Overview

ORR was defined as the percentage of participants with a best overall response (BOR) of complete response (CR) or partial response (PR), based on the investigator assessment of radiologic response according to Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1. No independent review of tumor assessments was performed. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (target or non-target) had to be reduced in short axis to less than (\<) 10 millimeter (mm). PR was defined as at least a 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum of diameters.

Participant Flow

Participants took part in the study at 14 investigative sites in the United States, Japan, Singapore, and Taiwan from 05 April 2013 to 2 November 2017.

A total of 25 participants with kinesin family 5B oncogene rearranged during transfection (KIF5B-RET)-positive adenocarcinoma of the lung or other RET translocations were enrolled and treated, 5 participants were ongoing in the Extension Phase at the time of data cut-off.

PRIMARY outcome

Timeframe: From first dose date until PD, development of unacceptable toxicity, withdrawal of consent, participant's choice to stop study treatment (up to approximately 2 years 10 months)

Population: FAS included all participants who received at least 1 dose of lenvatinib.

ORR was defined as the percentage of participants with a best overall response (BOR) of complete response (CR) or partial response (PR), based on the investigator assessment of radiologic response according to Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1. No independent review of tumor assessments was performed. CR was defined as disappearance of all target lesions.

Objective Response Rate (ORR)
16.0 percentage of participants
Interval 4.5 to 36.1

SECONDARY outcome

Timeframe: From first dose date until PD or death (up to approximately 2 years 10 months)

Population: FAS included all participants who received at least 1 dose of lenvatinib.

PFS was defined as the time from the first dose to the date of first documentation of PD, or date of death, whichever occurred first. Tumor response data used to analyze PFS was obtained from the investigator's assessment of the imaging scans using RECIST 1.1. No independent review of tumor assessments were performed. PFS was calculated using Kaplan-Meier estimate and presented with 2-sided 95% Cl based on the Greenwood formula. PD was defined as at least 20% increase (including an absolute increase of at least 5 mm) in the sum of diameters of target lesions.
