Clinical Trial Summary

The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called Lorlatinib) in health participants. This study is seeking participants who: - Must be male or female of 18 to 75 years of age, inclusive at the time of the study. - Are willing and able to comply with all scheduled visits, treatment plan, and other study procedures. - Have a BMI (body mass index) of 17.5 to 40 kg/m2; and a total body weight >50 kg (110 lb). - Are capable of giving signed informed consent document. All participants in this study will receive Lorlatinib. Participants will be placed into 1 of 3 cohorts based on their hepatic (liver) function. Participants will take Lorlatinib once by mouth. We will examine the experiences of people receiving the study medicine. This will help us determine if the study medicine is safe and effective. Participants will take part in this study for up to 35 days.


Description:

This is a Phase 1, open label, parallel group study to investigate the effect of moderate and severe hepatic impairment on the plasma PK, safety, and tolerability after a single oral 100 mg dose of lorlatinib under fasted conditions.

Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality or other conditions or situations related to COVID-19 pandemic (eg. Contact with positive case, residence, or travel to an area with high incidence) that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study. 4. Participants with an eGFR of = 60 mL/min/1.73 m2 based on the 2021 CKD-EPI equation, with a single repeat permitted to assess eligibility, if needed. 5. Concurrent use of any of the following prohibited concomitant medication(s) within 12 days prior to the first dose of lorlatinib: 1. Known strong CYP3A inhibitors (eg, boceprevir, cobicistat, clarithromycin, conivaptan, diltiazem, idelalisib, indinavir, itraconazole, ketoconazole, lopinavir, nefazodone, nelfinavir, posaconazole, ritonavir, saquinavir, telaprevir, tipranavir, troleandomycin, voriconazole, grapefruit juice or grapefruit/grapefruit-related citrus fruits [eg Seville oranges, pomelos]). The topical use of these medications (if applicable), such as 2% ketoconazole cream, is allowed. 2. Known strong CYP3A inducers (eg, carbamazepine, enzalutamide, mitotane, phenytoin, rifabutin, rifampin, St. John's Wort). 3. Known P-gp substrates with a narrow therapeutic index (eg, digoxin). 6.

Known hypersensitivity to lorlatinib or its excipients. 9. A positive urine drug test. Participants with moderate or severe hepatic impairment (Cohorts 1 and 2) will be eligible to participate if their urine drug test is positive with a drug for a prescribed condition that is not expected to interfere with the PK of lorlatinib. 10.

Additional Exclusion Criteria for Participants with Normal Hepatic Function (Cohort 3) - 1. Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies deemed relevant for participation in this study, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing). 2. History of regular alcohol consumption exceeding 7 drinks/week for females or 14 drinks/week for males (1 drink = 5 ounces (150 mL) of wine or 12 ounces (360 mL) of beer or 1.5 ounces (45 mL) of hard liquor) within 6 months of Screening. 3. Screening supine BP =140 mm Hg (systolic) or =90 mm Hg (diastolic), following at least 5 minutes of supine rest. If initial supine BP is =140 mm Hg (systolic) or =90 mm Hg (diastolic), the BP should be repeated 2 more times and the average of the 3 BP values should be used to determine the participant's eligibility. 4. Baseline standard 12-lead ECG that demonstrates clinically relevant abnormalities that may affect participant safety or interpretation of study results (eg, baseline QTcF interval >450 msec, complete LBBB, signs of an acute or indeterminate age myocardial infarction, ST T interval changes suggestive of myocardial ischemia, second or third degree AV block, baseline PR interval >200, or serious bradyarrhythmias or tachyarrhythmias). If the baseline uncorrected QT interval is >450 msec, this interval should be rate corrected using the Fridericia method and the resulting QTcF should be used for decision making and reporting. If QTcF exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated 2 more times and the average of the 3 QTcF or QRS values should be used to determine the participant's eligibility. Computer interpreted ECGs should be overread by a physician experienced in reading ECGs before excluding a participant. 5. Use of prescription or nonprescription drugs and dietary supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study medication. As an exception, acetaminophen/paracetamol may be used at doses of =1 g/day. Limited use of nonprescription medications that are not believed to affect participant safety or the overall results of the study may be permitted on a case by case basis following approval by the Sponsor. Herbal supplements and HRT must have been discontinued at least 28 days prior to the dose of lorlatinib. 6. Participants with a history of or current positive results for hepatitis B or hepatitis C, including HBsAg, HBcAb, or HCVAb. Additional Exclusion Criteria for Participants with Moderate and Severe Hepatic Impairment (Cohorts 1 and 2) - 1. Other clinically significant disease that contraindicates study drug or that may affect the PK of lorlatinib. 2. Hepatic carcinoma and hepatorenal syndrome. 3. Undergone porta-caval shunt surgery. 4. History of gastrointestinal hemorrhage due to esophageal varices or peptic ulcers less than 1 month prior to study entry. 5. Any clinically significant laboratory abnormality except for those parameters influenced by hepatic impairment. 6. Presence of clinically active Stage 2, 3 or 4 encephalopathy. 7. Severe uncontrolled ascites and/or pleural effusion. 8. Screening supine BP =160 mm Hg (systolic) or =90 mm Hg (diastolic), on a single measurement following at least 5 minutes of rest. If initial supine BP is =160 mm Hg (systolic) or =90 mm Hg (diastolic), the BP should be repeated 2 more times and the average of the three BP values should be used to determine the participant's eligibility. 9. Screening supine 12-lead ECG demonstrating QTcF >470 msec. If initial QTcF exceeds 470 msec, the ECG should be repeated two more times and the average of the three QTcF values should be used to determine the participant's eligibility. 10. Second-degree or third-degree AV block (unless paced) or baseline PR interval >200 msec at any time prior to dosing of study treatment.
