Pharmacodynamics

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 Label.

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) Label. Among the 284 patients with PR interval <200 ms at baseline, 14% had PR interval prolongation ≥200 ms after starting use with lorlatinib Label. The prolongation of PR interval occurred in a concentration-dependent manner and atrioventricular block occurred in 1% of patients Label.

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 Label.

Mechanism of action

Non-small cell lung cancer (NSCLC) accounts for up to 85% of lung cancer cases worldwide and remains a particularly difficult to treat condition 10. The gene rearrangement of anaplastic lymphoma kinase (ALK) is a genetic alteration that drives the development of NSCLC in a number of patients 6,7. 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 2,5,6.

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 Label. 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 Label. Moreover, lorlatinib possesses the capability to cross the blood-brain barrier, allowing it to reach and treat progressive or worsening brain metastases as well 10,5. The overall antitumor activity of lorlatinib in in-vivo models appears to be dose-dependent and correlated with the inhibition of ALK phosphorylation Label.

Although many ALK-positive metastatic NSCLC patients respond to initial tyrosine kinase therapies, such patients also often experience tumor progression 8. 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 9.

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 Label.

The mean absolute bioavailability is 81% (90% CI 75.7%, 86.2%) after oral administration compared to intravenous administration Label.

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 Label.

Volume of distribution

The mean (CV%) steady-state volume of distribution (Vss) was 305 L (28%) following a single intravenous dose Label.

Protein binding

In vitro, lorlatinib was 66% bound to plasma proteins at a concentration of 2.4 µM Label. The blood-to-plasma ratio was 0.99 Label.

Metabolism

In vitro, lorlatinib is metabolized primarily by CYP3A4 and UGT1A4, with minor contribution from CYP2C8, CYP2C19, CYP3A5, and UGT1A3 Label. 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 Label. The oxidative cleavage metabolite, M8, is pharmacologically inactive Label.

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) Label.

Half-life

The mean plasma half-life (t½) of lorlatinib was 24 hours (40%) after a single oral 100 mg dose of lorlatinib Label.

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 Label.

Toxicity

Although there is no formal data available on the use of lorlatinib in pregnant women, based on findings from animal studies and its mechanism of action, it is believed that lorlatinib can cause embryo-fetal harm when administered to a pregnant woman Label.

There are no data on the presence of lorlatinib or its metabolites in either human or animal milk or its effects on the breastfed infant or on milk production Label. Because of the potential for serious adverse reactions in breastfed infants, instruct women not to breastfeed during treatment with lorlatinib and for 7 days after the final dose Label.

Advise female patients of reproductive potential to use effective non-hormonal contraception during treatment with lorlatinib and for at least 6 months after the final dose Label. Advise females of reproductive potential to use a non-hormonal method of contraception, because lorlatinib can render hormonal contraceptives ineffective Label.

Based on genotoxicity findings, advise males with female partners of reproductive potential to use effective contraception during treatment with lorlatinib and for at least 3 months after the final dose Label.

Based on findings from animal studies, use of lorlatinib may transiently impair male fertility Label.

The safety and effectiveness of lorlatinib in pediatric patients have not been established Label.

Of the 295 patients in Study B7461001 who received 100 mg lorlatinib orally once daily, 18% of patients were aged 65 years or older Label. Although data are limited, no clinically important differences in safety or efficacy were observed between patients aged 65 years or older and younger patients Label.

No dose adjustment is recommended for patients with mild hepatic impairment (total bilirubin ≤ upper limit of normal [ULN] with AST > ULN or total bilirubin >1 to 1.5 × ULN with any AST) Label. The recommended dose of lorlatinib has not been established for patients with moderate or severe hepatic impairment Label.

No dose adjustment is recommended for patients with mild or moderate renal impairment (creatinine clearance [CLcr] 30 to 89 mL/min estimated by Cockcroft-Gault) Label. The recommended dose of lorlatinib has not been established for patients with severe renal impairment Label.

Carcinogenicity studies have not been conducted with lorlatinib Label. Lorlatinib was aneugenic in an in vitro assay in human lymphoblastoid TK6 cells and positive for micronuclei formation in vivo in the bone marrow of rats. Lorlatinib was not mutagenic in an in vitro bacterial reverse mutation (Ames) assay Label.

Dedicated fertility studies were not conducted with lorlatinib Label. Findings in male reproductive organs occurred in repeat-dose toxicity studies and included lower testicular, epididymal, and prostate weights; testicular tubular degeneration/atrophy; prostatic atrophy; and/or epididymal inflammation at 15 mg/kg/day and 7 mg/kg/day in rats and dogs, respectively (approximately 8 and 2 times, respectively, the human exposure at the recommended dose of 100 mg based on AUC) Label. The effects on male reproductive organs were reversible Label.

Distended abdomen, skin rash, and increased cholesterol and triglycerides occurred in animals Label. These findings were accompanied by hyperplasia and dilation of the bile ducts in the liver and acinar atrophy of the pancreas in rats at 15 mg/kg/day and in dogs at 2 mg/kg/day (approximately 8 and 0.5 times, respectively, the human exposure at the recommended dose of 100 mg based on AUC) Label. All effects were reversible within the recovery period Label.
