ZELBORAF

ZELBORAF is an FDA-registered drug product whose active ingredient is VEMURAFENIB. It is labelled by Genentech, Inc. taken by oral and marketed as a human prescription drug product. Identifiers on file: NDC 50242-090, application NDA202429, label effective 20260828. This page reproduces the FDA-approved label text so you can check what a product is, who makes it and how it is supplied before discussing it with a pharmacist or prescriber.

Across FDA labelling, products containing VEMURAFENIB are most often described in connection with: treatment patients, braf mutation, unresectable metastatic, zelboraf indicated, detected fda-approved, erdheim-chester disease, kinase inhibitor, erdheim- chester. Wording differs between labels, and the full indications section on this page takes precedence when it is present.

1 INDICATIONS AND USAGE ZELBORAF ® is a kinase inhibitor indicated for the treatment of patients with unresectable or metastatic melanoma with BRAF V600E mutation as detected by an FDA-approved test. ( 1.1 , 2.1 ) ZELBORAF ® is indicated for the treatment of patients with Erdheim- Chester Disease with BRAF V600 mutation. ( 1.2 , 2.1 ) Limitation of Use: ZELBORAF is not indicated for treatment of patients with wild-type BRAF melanoma ( 2.1 , 5.2 ) 1.1 Unresectable or Metastatic Melanoma ZELBORAF ® is indicated for the treatment of patients with unresectable or metastatic melanoma with BRAF V600E mutation as detected by an FDA-approved test. Limitation of Use: ZELBORAF is not indicated for treatment of patients with wild-type BRAF melanoma [see Warnings and Precautions (5.2) ] . 1.2 Erdheim-Chester Disease ZELBORAF ® is indicated for the treatment of patients with Erdheim-Chester Disease (ECD) with BRAF V600 mutation.

2 DOSAGE AND ADMINISTRATION Confirm the presence of BRAF V600E mutation in tumor specimens prior to initiation of treatment with ZELBORAF. ( 2.1 ) Recommended dose: 960 mg orally twice daily taken approximately 12 hours apart with or without a meal. ( 2.2 ) 2.1 Patient Selection for Treatment of Melanoma Confirm the presence of BRAF V600E mutation in melanoma tumor specimens prior to initiation of treatment with ZELBORAF [see Warnings and Precautions (5.2) ] . Information on FDA-approved tests for the detection of BRAF V600 mutations in melanoma is available at http://www.fda.gov/CompanionDiagnostics. 2.2 Recommended Dose The recommended dose of ZELBORAF is 960 mg (four 240 mg tablets) orally every 12 hours with or without a meal. A missed dose can be taken up to 4 hours prior to the next dose. Treat patients with ZELBORAF until disease progression or unacceptable toxicity occurs. Do not take an additional dose if vomiting occurs after ZELBORAF administration, but continue with the next scheduled dose. Do not crush or chew the tablets. 2.3 Dose Modifications For New Primary Cutaneous Malignancies: No dose modifications are recommended. For Other Adverse Reactions: Permanently discontinue ZELBORAF for any of the following: Grade 4 adverse reaction, first appearance (if clinically appropriate) or second appearance QTc prolongation > 500 ms and increased by > 60 ms from pre-treatment values [see Warnings and Precautions (5.5) ] Withhold ZELBORAF for NCI-CTCAE (v4.0) intolerable Grade 2 or greater adverse reactions. Upon recovery to Grade 0–1, restart ZELBORAF at a reduced dose as follows: 720 mg twice daily for first appearance of intolerable Grade 2 or Grade 3 adverse reactions 480 mg twice daily for second appearance of Grade 2 (if intolerable) or Grade 3 adverse reactions or for first appearance of Grade 4 adverse reaction (if clinically appropriate) Do not dose reduce to below 480 mg twice daily. 2.4 Dose Modification for Strong CYP3A4 Inducers Avoid concomitant use of strong CYP3A4 inducers during treatment with ZELBORAF [see Drug Interactions (7.1) and Clinical Pharmacology (12.3) ] . If concomitant use of a strong CYP3A4 inducer is unavoidable, increase the dose of ZELBORAF by 240 mg (one tablet) as tolerated. After discontinuation of a strong CYP3A4 inducer for two weeks, resume the ZELBORAF dose that was taken prior to initiating the strong CYP3A4 inducer.

6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the label: New Primary Malignancies [see Warnings and Precautions (5.1) ] Hypersensitivity Reactions [see Warnings and Precautions (5.3) ] Dermatologic Reactions [see Warnings and Precautions (5.4) ] QT Prolongation [see Warnings and Precautions (5.5) ] Hepatotoxicity [see Warnings and Precautions (5.6) ] Photosensitivity [see Warnings and Precautions (5.7) ] Ophthalmologic Reactions [see Warnings and Precautions (5.8) ] Radiation Sensitization and Radiation Recall [see Warnings and Precautions (5.10) ] Renal Failure [see Warnings and Precautions (5.11) ] Dupuytren's Contracture and Plantar Fascial Fibromatosis [see Warnings and Precautions (5.12) ] Melanoma: Most common adverse reactions (≥ 30%) are arthralgia, rash, alopecia, fatigue, photosensitivity reaction, nausea, pruritus, and skin papilloma.

Unresectable or Metastatic Melanoma with BRAF V600E Mutation This section describes adverse drug reactions (ADRs) identified from analyses of Trial 1 and Trial 2 [see Clinical Studies (14) ] . Trial 1 randomized (1:1) 675 treatment-naive patients with unresectable or metastatic melanoma to receive ZELBORAF 960 mg orally twice daily or dacarbazine 1000 mg/m 2 intravenously every 3 weeks. In Trial 2, 132 patients with metastatic melanoma and failure of at least one prior systemic therapy received treatment with ZELBORAF 960 mg orally twice daily. Table 1 presents adverse reactions reported in at least 10% of unresectable or metastatic melanoma patients treated with ZELBORAF. The most common adverse reactions of any grade (≥ 30% in either study) in ZELBORAF-treated patients were arthralgia, rash, alopecia, fatigue, photosensitivity reaction, nausea, pruritus, and skin papilloma. The most common (≥ 5%) Grade 3 adverse reactions were cuSCC and rash. The incidence of Grade 4 adverse reactions was ≤ 4% in both studies. The incidence of adverse events resulting in permanent discontinuation of study medication in Trial 1 was 7% for the ZELBORAF arm and 4% for the dacarbazine arm. In Trial 2, the incidence of adverse events resulting in permanent discontinuation of study medication was 3% in ZELBORAF-treated patients. The median duration of study treatment was 4.2 months for ZELBORAF and 0.8 months for dacarbazine in Trial 1, and 5.7 months for ZELBORAF in Trial 2.

Table 3 presents adverse reactions reported in at least 20% of BRAF V600 mutation-positive ECD patients treated with ZELBORAF. In Trial 4, the most commonly reported adverse reactions (> 50%) in patients with BRAF V600 mutation- positive ECD treated with ZELBORAF were arthralgia, rash maculo-papular, alopecia, fatigue, electrocardiogram QT interval prolonged, and skin papilloma.

Skin and subcutaneous tissue disorders: Drug reaction with eosinophilia and systemic symptoms (DRESS syndrome) [see Warnings and Precautions (5.3) ] . Blood and lymphatic systems disorder: Neutropenia Injury, poisoning and procedural complications: Radiation sensitization and recall [see Warnings and Precautions (5.10) ].
