The factors, or reasons, that allow a person to participate in a clinical study.
Show details

- Male and female participants who are overtly healthy as determined by medical
evaluation including medical history, physical examination, laboratory tests, and ECG.

- Adequate Renal Function, including:

Estimated creatinine clearance ≥90 mL/min as calculated using chronic kidney disease
epidemiology collaboration equation (CKD EPI). In equivocal cases, a 24 hour urine

compliance with the requirements and restrictions listed in the informed consent
document (ICD) and in this

Exclusion criteria
The factors, or reasons, that prevent a person from participating in a clinical study.
Show details

- Evidence or history of clinically significant hematological, renal, endocrine,
pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological, or
allergic disease (including drug allergies, but excluding untreated, asymptomatic,
seasonal allergies at the time of dosing).

- Other acute or chronic medical or psychiatric condition including recent (within the
past year) or active suicidal ideation or behavior or laboratory abnormality that may
increase the risk associated with study participation or investigational product
administration or may interfere with the interpretation of study results and, in the
judgment of the investigator, would make the participant inappropriate for entry into
this study. Psychiatric adverse experiences have been reported in patients treated
with modafinil with many, but not all, with prior psychiatric history. Participants
with a history of psychosis, depression, or mania are excluded from this study.

- Use of prescription or nonprescription drugs and dietary and herbal supplements within
7 days or 5 half lives (whichever is longer) prior to the first dose of
investigational product. 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.

- Previous administration with lorlatinib within 30 days (or as determined by the local
requirement) or 5 half lives preceding the first dose of lorlatinib used in this study
(whichever is longer).

- Previous treatment with lorlatinib

- A positive urine drug test, as confirmed by a single repeat.

- Screening supine blood pressure (BP) ?130 mm Hg (systolic) or ?80 mm Hg (diastolic),
following at least 5 minutes of supine rest. If BP is ?130 mm Hg (systolic) or ?80 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.

- History of pancreatitis (elevated amylase or lipase) or hyperlipidemia.

- Screening supine 12 lead ECG demonstrating PR interval >200 msec, corrected QT (QTc)
>450 msec or a QRS interval >120 msec.

>50, and occasional asymptomatic premature atrial contraction and premature
ventricular contractions), history of atrioventricular (AV) block, history of
symptomatic bradycardia, history of QTc prolongation.

- Participants with ANY of the following abnormalities in clinical laboratory tests at
screening: Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) level >
upper limit of normal (ULN); Total bilirubin level > ULN; participants with a history
of Gilbert's syndrome may have direct bilirubin measured and would be eligible for
this study provided the direct bilirubin level is ? ULN.

- History of alcohol abuse or binge drinking and/or any other illicit drug use or
dependence within 6 months of Screening. Binge drinking is defined as a pattern of 5
(male) and 4 (female) or more alcoholic drinks in about 2 hours. As a general rule,
alcohol intake should not exceed 14 units per week for males or 7 units per week for
females (1 unit = 8 ounces (240 mL) beer, 1 ounce (30 mL) of 40% spirit or 3 ounces
(90 mL) of wine).

- As modafinil is a controlled substance, participants with a history drug abuse will be
excluded.

within 60 days prior to dosing.

- History of sensitivity to lorlatinib or modafinil.

- Unwilling or unable to comply with the criteria in the Lifestyle Considerations
section of this protocol.

- Male participants with partners currently pregnant; male participants able to father
children who are unwilling or unable to use a highly effective method of contraception
as outlined in this protocol for the duration of the study and for at least 97 days
after the last dose of investigational product or longer based upon the compound's
half life characteristics, and refrain from sperm donation for the duration of the
study and for at least 97 days after the last dose of investigational product.

- Investigator site staff members directly involved in the conduct of the study and
their family members, site staff members otherwise supervised by the investigator, or
Pfizer employees, including their family members, directly involved in the conduct of
the study.

Descriptive Information
Brief Title  ICMJE Effect of Multiple Doses of Modafinil on the Pharmacokinetics of Single Dose Lorlatinib in Healthy Participants
Official Title  ICMJE PHASE 1, OPEN-LABEL, FIXED SEQUENCE, 2-PERIOD STUDY TO INVESTIGATE THE EFFECT OF MULTIPLE DOSES OF MODAFINIL ON THE PHARMACOKINETICS OF SINGLE DOSE LORLATINIB (PF-06463922) IN HEALTHY PARTICIPANTS
Brief Summary

The primary purpose of the study is to characterize the safety profile of lorlatinib in the presence of a moderate CYP3A4/5 inducer, modafinil. In another drug-drug interaction study for lorlatinib coadministered with a strong CYP3A4/5 inducer, rifampin, all participants experienced increases in liver enzymes after receiving the combination of a single dose lorlatinib (100 mg) with rifampin (600 mg daily (QD)) after multiple doses of rifampin. The AST and ALT continued to increase over the next 24-48 hours, but recovered below the upper limit of normal for all participants upon discontinuation of rifampin.

We hypothesize the combination of lorlatinib with the moderate CYP3A inducer modafinil will not have a safety findings related to liver enzyme elevation similar to what occurred in the study with rifampin and lorlatinib.

Detailed Description

This will be a Phase 1 study in approximately 16 healthy participants employing administration of a single dose of lorlatinib in the fasted state alone, and with multiple doses of modafinil 400 mg once daily. This study will consist of up to 3 lorlatinib treatment groups: 50, 75, or 100 mg single doses of lorlatinib given alone and in combination with multiple doses of modafinil.

Each enrolled participant will receive lorlatinib 50, 75, or 100 mg alone in Period 1 and then lorlatinib 50, 75, or 100 mg in combination with multiple dose modafinil in Period 2 after a washout period of at least 19 days between lorlatinib doses in Periods 1 and 2. A single PK sample is taken prior to lorlatinib dosing in each period. Following administration of lorlatinib in each period, participants will undergo serial PK sampling.

There will be 4 cohorts. Cohorts 1 to 3 will include 2 participants each, while Cohort 4 will include 10 participants. Participants in Cohorts 1 to 4 will be sequentially enrolled such that participants in a new cohort can receive their lorlatinib Period 2 dose only after participants from the prior cohort are 72 hours past their lorlatinib Period 2 combination dose (with modafinil) with no safety concerns. In addition, Cohorts 1 to 3 will employ sentinel dosing such that the second participant in each cohort can receive their lorlatinib Period 2 dose only after the first participant from the same cohort is 72 hours past their lorlatinib and modafinil Period 2 combination dose with no safety concerns. Participants in Cohort 4 may be dosed in parallel, as sentinel dosing of lorlatinib 100 mg will have been completed in Cohort 3. The overall study design will be identical in all 4 cohorts, with the only difference being the dose of lorlatinib administered.

The decision to dose subsequent cohorts during Period 2 with lorlatinib will be made after reviewing the totality of the participants' clinical picture for safety by the investigator. Furthermore, participants in subsequent cohorts will not be dosed if the following liver function abnormalities are observed during the 72 hour time frame for safety evaluation after lorlatinib dosing in Period 2.

For enrollment of each successive cohort, the period of safety evaluation will be at least 72 hours after the Period 2 lorlatinib dosing in the previous cohort. During Period 2, safety laboratory assessments including urinalysis, hematology and chemistry will be performed once daily from Day 14 through Day 20. Only after the review of safety labs for at least 72 hours after lorlatinib+ modafinil dosing during Period 2 of the previous cohort, will participants in a new cohort receive lorlatinib in combination with modafinil in their Period 2. Additional safety laboratory assessments may be performed at any additional times at the discretion of the investigator. If safety events of concern are observed in Cohorts 1, 2, or 3 during Period 2, this study will be terminated.
