Eli Lilly and Company

1 INDICATIONS AND USAGE

1.1 Metastatic RET Fusion-Positive Non-Small Cell Lung Cancer

RETEVMO™ is indicated for the treatment of adult patients with metastatic RET fusion-positive non-small cell lung cancer (NSCLC).

This indication is approved under accelerated approval based on overall response rate and duration of response [see Clinical Studies (14.1 )]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s).

1.2 RET -Mutant Medullary Thyroid Cancer

RETEVMO is indicated for the treatment of adult and pediatric patients 12 years of age and older with advanced or metastatic RET -mutant medullary thyroid cancer (MTC) who require systemic therapy.

This indication is approved under accelerated approval based on overall response rate and duration of response [see Clinical Studies (14.2 )]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s).

1.3 RET Fusion-Positive Thyroid Cancer

RETEVMO is indicated for the treatment of adult and pediatric patients 12 years of age and older with advanced or metastatic RET fusion-positive thyroid cancer who require systemic therapy and who are radioactive iodine-refractory (if radioactive iodine is appropriate).

This indication is approved under accelerated approval based on overall response rate and duration of response [see Clinical Studies (14.3 )]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s).

2 DOSAGE AND ADMINISTRATION

2.1 Patient Selection

Select patients for treatment with RETEVMO based on the presence of a RET gene fusion (NSCLC or thyroid cancer) or specific RET gene mutation (MTC) in tumor specimens or plasma [see Clinical Studies (14)]. An FDA-approved test for the detection of RET gene fusions and RET gene mutations is not currently available.

2.2 Important Administration Instructions

RETEVMO may be taken with or without food unless coadministrated with a proton pump inhibitor (PPI) [see Dosage and Administration (2.4), Clinical Pharmacology (12.3)].

2.3 Recommended Dosage

The recommended dosage of RETEVMO based on body weight is:

  • Less than 50 kg: 120 mg
  • 50 kg or greater: 160 mg

Take RETEVMO orally twice daily (approximately every 12 hours) until disease progression or unacceptable toxicity.

Swallow the capsules whole. Do not crush or chew the capsules.

Do not take a missed dose unless it is more than 6 hours until next scheduled dose.

If vomiting occurs after RETEVMO administration, do not take an additional dose and continue to the next scheduled time for the next dose.

2.4 Dosage Modifications for Concomitant Use of Acid-Reducing Agents

Avoid concomitant use of a PPI, a histamine-2 (H2) receptor antagonist, or a locally-acting antacid with RETEVMO [see Drug Interactions (7.1)]. If concomitant use cannot be avoided:

  • Take RETEVMO with food when coadministered with a PPI.
  • Take RETEVMO 2 hours before or 10 hours after administration of an H2 receptor antagonist.
  • Take RETEVMO 2 hours before or 2 hours after administration of a locally-acting antacid.

The recommended dosage modifications for adverse reactions are provided in Table 2.

Table 2: Recommended RETEVMO Dosage Modifications for Adverse Reactions
Adverse Reaction Severity Dosage Modification
Hepatotoxicity [see Warnings and Precautions (5.1)] Grade 3orGrade 4
  • Withhold RETEVMO and monitor AST/ALT once weekly until resolution to Grade 1 or baseline.
  • Resume at reduced dose by 2 dose levels and monitor AST and ALT once weekly until 4 weeks after reaching dose taken prior to the onset of Grade 3 or 4 increased AST or ALT.
  • Increase dose by 1 dose level after a minimum of 2 weeks without recurrence and then increase to dose taken prior to the onset of Grade 3 or 4 increased AST or ALT after a minimum of 4 weeks without recurrence.
Hypertension [see Warnings and Precautions (5.2)] Grade 3
  • Withhold RETEVMO for Grade 3 hypertension that persists despite optimal antihypertensive therapy. Resume at a reduced dose when hypertension is controlled.
Grade 4
  • Discontinue RETEVMO.
QT Interval Prolongation[see Warnings and Precautions (5.3)] Grade 3
  • Withhold RETEVMO until recovery to baseline or Grade 0 or 1.
  • Resume at a reduced dose.
Grade 4
  • Discontinue RETEVMO
Hemorrhagic Events[see Warnings and Precautions (5.4)] Grade 3orGrade 4
  • Withhold RETEVMO until recovery to baseline or Grade 0 or 1.
  • Discontinue RETEVMO for severe or life-threatening hemorrhagic events.
Hypersensitivity Reactions [see Warnings and Precautions (5.5)] All Grades
  • Withhold RETEVMO until resolution of the event. Initiate corticosteroids.
  • Resume at a reduced dose by 3 dose levels while continuing corticosteroids.
  • Increase dose by 1 dose level each week until the dose taken prior to the onset of hypersensitivity is reached, then taper corticosteroids.
