A Study of Lazertinib (JNJ-73841937) in Healthy Participants

Overview

The purpose of this study is to evaluate the effect of steady-state concentrations of lazertinib on the single-dose pharmacokinetics (PK) of probe substrates (midazolam, rosuvastatin, and metformin) in healthy adult participants.

Full Title of Study: “A Phase 1, Open-label, Study in Healthy Participants to Evaluate the Effect of Steady State Concentrations of Lazertinib (JNJ-73841937) on the Single-dose Pharmacokinetics of Probe Substrates (Midazolam, Rosuvastatin, and Metformin)”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: N/A
    • Intervention Model: Single Group Assignment
    • Primary Purpose: Basic Science
    • Masking: None (Open Label)
  • Study Primary Completion Date: December 30, 2021

Interventions

  • Drug: Lazertinib
    • Lazertinib tablets will be administered orally, alone or in combination with probe substrates.
  • Drug: Midazolam
    • Midazolam (cytochrome P450 3A4 [CYP3A4] substrate) will be administered orally as a syrup as a part of probe substrates.
  • Drug: Rosuvastatin
    • Rosuvastatin (breast cancer resistant protein [BCRP] substrate) tablet will be administered orally as a part of probe substrates.
  • Drug: Metformin
    • Metformin (organic cation transporter 1 [OCT1] substrate) will be administered orally as a syrup as a part of probe substrates.

Arms, Groups and Cohorts

  • Experimental: Lazertinib + Probe Substrates of Midazolam, Rosuvastatin, and Metformin
    • Participants will receive a single oral dose of probe substrates of midazolam, rosuvastatin, and metformin on Day 1 under fasted conditions followed by a single oral dose of lazertinib under fed conditions from Day 5 to Day 14 except Day 13 which is under fasted conditions and co-administered with probe substrates under fasted conditions on Day 13.

Clinical Trial Outcome Measures

Primary Measures

  • Plasma Concentration of Probe Substrates (Midazolam, Rosuvastatin, and Metformin) Co-administered with Lazertinib (Day 13) as Test Versus Plasma Concentration of Probe Substrates Administered Alone (Day 1) as Reference
    • Time Frame: Predose up to 12 hours postdose (Days 1 and 13)
    • Plasma samples will be analyzed to determine concentrations of midazolam and its metabolite 1-OH-midazolam, rosuvastatin, metformin, or lazertinib using a validated, specific, and sensitive method on Day 1 versus Day 13 as a part of drug-drug interaction (DDI) assessment.

Secondary Measures

  • Number of Participants with Adverse Events (AEs)
    • Time Frame: Up to 56 days
    • AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
  • Number of Participants with AEs by Severity
    • Time Frame: Up to 56 days
    • Number of participants with AEs by severity will be reported. AE severity is a clinical determination of the intensity of an AE and is assessed by using the standard grades as follows: Grade 1= mild, Grade 2= moderate, Grade 3= severe, Grade 4= life-threatening and Grade 5= death related to AE.
  • Number of Participants with Clinically Significant Changes in Laboratory Test Results
    • Time Frame: Up to 28 days
    • Number of participants with change in clinical laboratory test results (including hematology and serum chemistry) will be reported.
  • Number of Participants with Clinically Significant Abnormalities in 12-lead Electrocardiograms (ECGs)
    • Time Frame: Up to 28 days
    • Number of participants with clinically significant abnormalities in ECGs will be reported.
  • Number of Participants with Clinically Significant Abnormalities in Vital Signs
    • Time Frame: Up to 28 days
    • Number of participants with clinically significant abnormalities in vital signs (including temperature [oral], pulse rate, and blood pressure) will be reported.
  • Number of Participants with Clinically Significant Abnormalities in Physical Examination
    • Time Frame: Up to 28 days
    • Number of participants with clinically significant abnormalities in physical examination (including height and body weight) will be reported.
  • Plasma Concentrations of Lazertinib at steady-state
    • Time Frame: Predose on Day 7, 9, 11, 13, and 14
    • Plasma concentration of lazertinib at steady-state will be assessed.
  • Plasma Concentrations of Lazertinib Following Repeat Dosing for 10 Days
    • Time Frame: Day 14, 15, 16, 17, 21, and 28
    • Plasma concentration of lazertinib following repeat dosing for 10 days will be assessed.

Participating in This Clinical Trial

Inclusion Criteria

  • Healthy on the basis of medical history at screening only, and physical examination, vital signs, and 12-lead electrocardiogram (ECG) performed at screening and at admission to the study center – Healthy on the basis of clinical laboratory tests performed at screening and at admission to the study center. – A woman who is considered surgically sterile but not postmenopausal, must have a negative highly sensitive serum (beta-human chorionic gonadotropin [beta-hCG]) at screening and a negative urine pregnancy test on Study Day 1.
