Efficacy and Safety of Furmonertinib in Patients With Locally Advanced or Metastatic NSCLC With EGFR Exon 20 Insertion

Korábbi kezelés

• More than 3 prior systemic anticancer therapy regimens for locally advanced or metastatic NSCLC
• Previous interstitial lung disease (ILD), drug-induced ILD, radiation pneumonitis requiring steroid therapy; or having the clinical manifestations of suspected ILD
• AEs from prior anticancer therapy that have not resolved to Grade ≤ 1 except for alopecia, vitiligo, endocrinopathy managed with replacement therapy, or Grade ≤ 2 peripheral neuropathy.

Más betegség

• Severe acute or chronic infections
• History of or active clinically significant cardiovascular dysfunction

Laborértékek

• Prior treatment with any EGFR-targeting agents (e.g., EGFR tyrosine kinase inhibitors [TKIs], monoclonal antibodies, or bispecific antibodies).
• Mean resting corrected QT interval (QTc) > 470 msec, obtained from triplicate ECGs, using the screening clinic ECG machine derived Fridericia's formula (QTcF) value
• Clinically significant prolonged QT interval or other arrhythmia or clinical status considered by investigators that may increase the risk of prolonged QT interval (e.g., complete left bundle branch block, degree III atrioventricular block, second-degree heart block, PR interval > 250 msec, congenital long QT syndrome, family history of long QT syndrome, or unexplained sudden death under 40 years of age in first-degree relatives, serious hypokalemia, heart failure) or current use of the drugs that may lead to prolonged QT interval.
