Abstract 1302

Background

Lorlatinib, a potent, brain-penetrant 3rd-generation (gen) ALK/ROS1 tyrosine kinase inhibitor (TKI), is approved for the treatment of patients (pts) with ALK+ metastatic NSCLC whose disease has progressed on 2nd-gen ALK TKIs. The safety profile of lorlatinib has been previously reported; treatment-related adverse events (AEs) were primarily mild–moderate in severity and manageable through dose modification or standard medical therapy. Here, we report safety data in key subgroups of pts based on age, gender and race.

Methods

This analysis was based on 295 pts with ALK+ or ROS1+ advanced NSCLC, ± CNS metastases, enrolled in the ongoing ph 1/2 trial (NCT01970865) who received lorlatinib 100 mg once daily. All causality AEs were graded per CTCAE v4.03. Data cutoff was 02 Feb 2018.

Results

Of the 295 pts, 241 were aged <65 years (y) and 54 were ≥65 y. AEs were reported at frequencies of 99.6% and 100% in the <65 y and ≥65 y subgroups respectively; however, there were generally more AEs in the ≥65 y subgroup, e.g. anemia (<65 y: 13.7% vs ≥ 65 y: 25.9%), edema (51.5% vs 68.5%), cognitive effects (26.1% vs 40.7%), dyspnea (25.7% vs 37.0%) and fatigue (26.6% vs 35.2%). AEs were generally balanced between males (n = 125) and females (n = 170). Among Asian (n = 108) and non-Asian (n = 161) pts, AEs were reported at a similar incidence (99.1% vs 100%). Grade 3/4 and grade 5 AEs were reported, respectively, in 57.4% and 12.0% of Asian pts and 58.4% and 14.9% of non-Asian pts. There were generally more AEs in non-Asian pts (Table). With multiple dosing, there were no substantial differences in lorlatinib plasma exposure in Asian vs non-Asian pts and neither steady-state AUC nor Cmax met the threshold for dose-adjustment.Table:

Unspecified race (n = 26)

b

Clustered term comprising AEs that represent similar clinical symptoms/syndromes.

.

Conclusions

There were no clinically relevant differences in the AEs based on age or gender. The frequencies of most AEs known to be associated with lorlatinib were generally lower in Asian than in non-Asian pts; however, hypertriglyceridemia was more frequently reported in Asian vs non-Asian pts.
