Source: FDA, National Drug Code (US)  Revision Year: 2024 

1. Indications and Usage

OJEMDA is indicated for the treatment of patients 6 months of age and older with relapsed or refractory pediatric low-grade glioma (LGG) harboring a BRAF fusion or rearrangement, or BRAF V600 mutation.

This indication is approved under accelerated approval based on response rate and duration of response [see Clinical Studies (14)]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

2. Dosage and Administration

2.1 Patient Selection

Confirm the presence of BRAF fusion or rearrangement, or BRAF V600 mutation prior to initiation of treatment with OJEMDA [see Warnings and Precautions (5.6), Clinical Studies (14)]. An FDA approved test for the detection of BRAF fusion or rearrangement, or BRAF V600 mutation in relapsed or refractory pediatric LGG is not currently available.

2.2 Recommended Testing Before Initiating OJEMDA

Before initiating OJEMDA, evaluate liver function tests, including ALT, AST and bilirubin [see Warnings and Precautions (5.3)].

2.3 Recommended Dosage

The recommended dosage of OJEMDA based on body surface area (BSA) is 380 mg/m² orally once weekly (the maximum recommended dosage is 600 mg orally once weekly) with or without food [see Administration (2.4) and Clinical Pharmacology (12.3)] until disease progression or intolerable toxicity. OJEMDA may be administered as an immediate release tablet (see Table 1) or as an oral suspension (see Table 2). A recommended dosage for patients with BSA less than 0.3 m² has not been established.

1 OJEMDA for oral suspension has a concentration of 25 mg/mL. Each bottle of OJEMDA for oral suspension delivers 300 mg/12 mL.

Continue once weekly dosing until disease progression or intolerable toxicity.

2.4 Administration

  • Take OJEMDA at a regularly scheduled time once weekly.
  • OJEMDA may be taken with or without food [see Clinical Pharmacology (12.3)].

If a dose is missed by:

  • 3 days or less, take the missed dose as soon as possible, and take the next dose on its regularly scheduled day.
  • more than 3 days, skip the missed dose and take the next dose on its regularly scheduled day.

If vomiting occurs immediately after taking a dose, repeat that dose.

OJEMDA tablets:

  • Swallow tablets whole with water.
  • Do not chew, cut, or crush.

OJEMDA for oral suspension:

  • Prior to first time use of OJEMDA for oral suspension, ensure that caregivers (and if appropriate, patients) read and understand the “Instructions for Use” before preparing, measuring, and administering OJEMDA.

Preparation and Administration

  • Reconstitute the powder in each supplied bottle with exactly 14 mL of room temperature water to form the OJEMDA for oral suspension. After reconstitution each mL contains 25 mg of tovorafenib. Product foaming after reconstitution reduces the deliverable volume.
  • Each bottle delivers 300 mg of tovorafenib in 12 mL. For doses greater than 300 mg, reconstitute two bottles to achieve the dose. Split the dose as equally as possible between the two bottles (e.g., 6 mL and 7 mL for a 325 mg dose).
  • Administer OJEMDA for oral suspension using the supplied oral dosing syringe or feeding tube (minimum 12 French) immediately after preparation.
  • If the OJEMDA for oral suspension is not administered within 15 minutes after preparation, instruct the patient to discard it.
