Lorlatinib is a third-generation anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor (TKI) indicated for the treatment of patients with ALK-positive metastatic non-small cell lung cancer (NSCLC) whose disease has progressed on a) the prior use of crizotinib and at least one other ALK inhibitor for metastatic disease, or b) the prior use of alectinib as the first ALK inhibitor therapy for metastatic disease, or c) the prior use of certinib as the first ALK inhibitor therapy for metastatic disease.
FDA Label
Lorviqua as monotherapy is indicated for the treatment of adult patients with anaplastic lymphoma kinase (ALK)positive advanced nonsmall cell lung cancer (NSCLC) previously not treated with an ALK inhibitor.
Lorviqua as monotherapy is indicated for the treatment of adult patients with ALKpositive advanced NSCLC whose disease has progressed after:
- alectinib or ceritinib as the first ALK tyrosine kinase inhibitor (TKI) therapy; or
- crizotinib and at least one other ALK TKI.
Based on data from Study B7461001, exposure-response relationships for Grade 3 or 4 hypercholesterolemia and for any Grade 3 or 4 adverse reaction were observed at steady-state exposures achieved at the recommended dosage, with higher probability of the occurrence of adverse reactions with increasing lorlatinib exposure. In 295 patients who received lorlatinib at the recommended dosage of 100 mg once daily and had an ECG measurement in the same Study B7461001, the maximum mean change from baseline for their PR interval was 16.4 ms (2-sided 90% upper confidence interval [CI] 19.4 ms). Among the 284 patients with PR interval <200 ms at baseline, 14% had PR interval prolongation 200 ms after starting use with lorlatinib. The prolongation of PR interval occurred in a concentration-dependent manner and atrioventricular block occurred in 1% of patients. Finally, in 275 patients who received lorlatinib at the recommended dosage in the activity-estimating portion of Study B7461001, no large mean increases from baseline in the QTcF interval (i.e., >20 ms) were detected.

Absorption
The median lorlatinib Tmax was 1.2 hours (0.5 to 4 hours) following a single oral 100 mg dose and 2 hours (0.5 to 23 hours) following 100 mg orally once daily at steady state. The mean absolute bioavailability is 81% (90% CI 75.7%, 86.2%) after oral administration compared to intravenous administration. Administration of lorlatinib with a high fat, high-calorie meal (approximately 1000 calories with 150 calories from protein, 250 calories from carbohydrate, and 500 to 600 calories from fat) had no clinically meaningful effect on lorlatinib pharmacokinetics.
Route of Elimination
Following a single oral 100 mg dose of radiolabeled lorlatinib, 48% of the radioactivity was recovered in urine (<1% as unchanged) and 41% in feces (about 9% as unchanged).
Volume of Distribution
The mean (CV%) steady-state volume of distribution (Vss) was 305 L (28%) following a single intravenous dose.
Clearance
The mean oral clearance (CL/F) was 11 L/h (35%) following a single oral 100 mg dose and increased to 18 L/h (39%) at steady state, suggesting autoinduction.
In vitro, lorlatinib is metabolized primarily by CYP3A4 and UGT1A4, with minor contribution from CYP2C8, CYP2C19, CYP3A5, and UGT1A3. In plasma, a benzoic acid metabolite (M8) of lorlatinib resulting from the oxidative cleavage of the amide and aromatic ether bonds of lorlatinib accounted for 21% of the circulating radioactivity in a human [14C] mass balance study. The oxidative cleavage metabolite, M8, is pharmacologically inactive.
The mean plasma half-life (t) of lorlatinib was 24 hours (40%) after a single oral 100 mg dose of lorlatinib.
Non-small cell lung cancer (NSCLC) accounts for up to 85% of lung cancer cases worldwide and remains a particularly difficult to treat condition. The gene rearrangement of anaplastic lymphoma kinase (ALK) is a genetic alteration that drives the development of NSCLC in a number of patients. Ordinarily, ALK is a natural endogenous tyrosine kinase receptor that plays an important role in the development of the brain and elicits activity on various specific neurons in the nervous system. Subsequnetly, lorlatinib is a kinase inhibitor with in vitro activity against ALK and number of other tyrosine kinase receptor related targets including ROS1, TYK1, FER, FPS, TRKA, TRKB, TRKC, FAK, FAK2, and ACK. Lorlatinib demonstrated in vitro activity against multiple mutant forms of the ALK enzyme, including some mutations detected in tumors at the time of disease progression on crizotinib and other ALK inhibitors. Moreover, lorlatinib possesses the capability to cross the blood-brain barrier, allowing it to reach and treat progressive or worsening brain metastases as well. The overall antitumor activity of lorlatinib in in-vivo models appears to be dose-dependent and correlated with the inhibition of ALK phosphorylation. Although many ALK-positive metastatic NSCLC patients respond to initial tyrosine kinase therapies, such patients also often experience tumor progression. Various clinical trials performed with lorlatinib, however, have demonstrated its utility to effect tumor regression in ALK-positive metastatic NSCLC patients who experience tumor progression despite current use or having already used various first and second-generation tyrosine kinase inhibitors like crizotinib, alectinib, or ceritinib.
