Trial Outcomes & Findings for Real-World Effectiveness of Afatinib (Gilotrif) Following Immunotherapy in the Treatment of Metastatic, Squamous Cell Carcinoma of the Lung: A Multi-Site Retrospective Chart Review Study in the U.S. (NCT NCT04750824)

NCT ID: NCT04750824

Last Updated: 2024-09-19

Results Overview

ORR was defined as the percentage of patients with a complete response (CR) or partial response (PR) out of all patients (CR+PR/all patients) at initial response assessment and best response (response based on the scan where the patient showed the best response to treatment (not progression)). Charted/physician-reported (physician-provided information as recorded in patient's chart) ORR is reported.

Participant Flow

This was a non-interventional, retrospective, United States (US), multi-site, cohort study based on existing data from medical records of patients with Neuregulin-1 (NRG1) gene fusion-positive solid tumors treated with afatinib or other systemic therapy.

Only subjects that met all inclusion and none of the exclusion criteria were included.

Population: All patients who initiated index therapy (i.e., afatinib in any line; other systemic therapy among those without any history of afatinib) between 01 January 2017 and 31 March 2020.

PFS was defined as time from initiation of a line of therapy until disease progression or death; patients on therapy at the time of data cut-off were censored on the last date of treatment. Patients who discontinued a line of therapy for a reason other than disease progression but who subsequently die prior to the receipt of any other therapy were considered an event on the date of death. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1): Progressive disease (PD): at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study), or unequivocal progression of existing non-target lesions, or the appearance of one or more new lesions. In addition to the relative increase of 20%, the sum must also have demonstrated an absolute increase of at least 5 millimeter (mm).

PRIMARY outcome

Timeframe: From the index date (i.e., anytime between 01-January-2017 and 31-March-2020) until data collection (i.e. 11-Nov-2020 to 20-Jan-2021), up to 4 years and 19 days.

Population: All patients who initiated index therapy (i.e., afatinib in any line; other systemic therapy among those without any history of afatinib) between 01 January 2017 and 31 March 2020.

TTP was defined as time from initiation of a line of therapy until discontinuation due to disease progression. Patients on therapy or those who discontinued due to a reason other than disease progression were censored on the last date of treatment.

Number of patients who experienced any averse drug reactions (ADRs) during index treatment line is reported. An ADR was defined as a response to a medicinal product which is noxious and unintended. Response in this context means that a causal relationship between a medicinal product and an adverse event (AE) is at least a reasonable possibility.
