Lung Icon

GAVRETO was generally well tolerated in patients with RET+ mNSCLC1

mNSCLC=metastatic non–small cell lung cancer; RET+=rearranged during transfection positive.

Lung patient safety

Safety of GAVRETO was evaluated in 220 patients with RET+ mNSCLC in ARROW1


of patients permanently discontinued GAVRETO
due to any adverse reaction1


discontinued due to adverse reactions considered treatment-related by the trial investigator34

Adverse reactions resulting in permanent discontinuation which occurred in >1 patient included pneumonitis (1.8%), pneumonia (1.8%), and sepsis (1%).

Dose modifications and interruptions in RET fusion+ mNSCLC1

Dose reductions due to an adverse reaction occurred in 36% of patients treated with GAVRETO

Adverse reactions requiring dosage reductions in ≥2% of patients included neutropenia, anemia, pneumonitis, neutrophil count decreased, fatigue, hypertension, pneumonia, and leukopenia.

Dosage interruptions due to an adverse reaction occurred in 60% of patients treated with GAVRETO

Adverse reactions requiring dosage interruption in ≥2% of patients included neutropenia, pneumonitis, anemia, hypertension, pneumonia, pyrexia, increased aspartate aminotransferase (AST), increased blood creatine phosphokinase, fatigue, leukopenia, thrombocytopenia, vomiting, increased alanine aminotransferase (ALT), sepsis, and dyspnea.

Adverse reactions (≥15%) in RET fusion-positive mNSCLC patients who received GAVRETO in ARROW

††Denominator for each laboratory parameter is based on the number of patients with a baseline and post-treatment laboratory value available, which ranged from 216 to 218 patients.
Clinically relevant laboratory abnormalities in <20% of patients who received GAVRETO included increased phosphate (10%).

Adverse reactions (≥15%) and Grades 3-4 laboratory abnormalities (≥2%) in RET fusion-positive mNSCLC patients within the exploratory follow-up analyses were generally consistent with the pivotal data included in the U.S. Prescribing Information (USPI)1,34
