Registration Number
NCT07185997
Lead Sponsor
ArriVent BioPharma, Inc.
Brief Summary

Global, Phase 3, randomized, multicenter, open-label study evaluating the efficacy and safety of firmonertinib at a dose level of 240 mg QD compared to investigator's choice of osimertinib (80 mg QD) or afatinib (40 mg QD) in participants who have locally advanced or metastatic NSCLC with EGFR PACC mutations, and who have not received any prior therapy for advanced disease. Participants will be randomized in a 1:1 ratio to treatment with firmonertinib or osimertinib or afatinib and will take the assigned dose daily.

Primary Outcome Measures
NameTimeMethod
Progression Free Survival (PFS) determined by blinded independent central review (BICR)Until progression or death, assessed up to approximately 4 years

PFS is defined as the time from randomization to the first occurrence of disease progression as determined by BICR using RECIST v1.1, or death from any cause, whichever occurs first.

Confirmed overall response rate (ORR) as determined by BICRUntil progression or death, assessed up to approximately 3 years

Confirmed ORR is defined as the percentage of participants with a confirmed CR or PR based on BICR assessment relative to the total number of participants.

Secondary Outcome Measures
NameTimeMethod
Overall survival (OS)Until death, assessed up to approximately 5 years

OS is defined as the time from randomization to death from any cause.

Investigator-assessed PFSUntil progression or death, assessed up to approximately 4 years

Investigator-assessed PFS is defined as the time from randomization to the first documented disease progression or death, whichever occurs first, based on investigator assessment per RECIST v1.1.

Investigator-assessed confirmed ORRUntil progression or death, assessed up to approximately 3 years

Investigator-assessed confirmed ORR is defined as the percentage of participants with a confirmed CR or PR based on investigator assessment relative to the total number of participants.

Duration of response (DOR)Until progression or death, assessed up to approximately 4 years

DOR is defined as the time from first documented evidence of CR or PR until the first documented evidence of disease progression or death, whichever occurs first.

Time to second Progression-free survival (PFS2)Assessed up to approximately 5 years

PFS2 is defined as the time from randomization to second progression (ie, earliest of the subsequent progression events after initiation of a new anti-cancer treatment), or death from any cause, whichever occurs first.

Incidence and severity of adverse events (AEs), as a measure of safety and tolerability of firmonertinibAssessed up to approximately 5 years

An AE is defined as any unfavorable or unintended medical occurrence in a trial participant administered a pharmaceutical product, regardless of causal attribution.

Change from baseline in safety-related clinical laboratory test resultsAssessed up to approximately 5 years

Safety-related laboratory parameters include absolute neutrophil count, hemoglobin, platelet count, albumin, blood urea nitrogen (BUN), chloride, creatinine, potassium, sodium, alkaline phosphatase (ALP), alanine aminotransferase (ALT); aspartate aminotransferase (AST), total bilirubin. Each parameter is measured using its standard unit. Changes in participants' laboratory test values are evaluated by comparing baseline (pre-treatment) results with those obtained at prespecified time points during or following the treatment.
