Lazertinib, sold under the brand name Lazcluze among others, is an anti-cancer medication used for the treatment of non-small cell lung cancer. [2] [5] [6] It is a kinase inhibitor of epidermal growth factor receptor. [2]
The most common adverse reactions include rash, nail toxicity, infusion-related reactions (amivantamab), musculoskeletal pain, edema, stomatitis, venous thromboembolism, paresthesia, fatigue, diarrhea, constipation, COVID-19 infection, hemorrhage, dry skin, decreased appetite, pruritus, nausea, and ocular toxicity. [5]
Lazertinib was approved for medical use in South Korea in January 2021, [7] [8] in the United States in August 2024, [5] [9] [10] [11] and in the European Union in January 2025. [3] [4]
Lazertinib is indicated in combination with amivantamab for the first-line treatment of adults with locally advanced or metastatic non-small cell lung cancer with epidermal growth factor receptor exon 19 deletions or exon 21 L858R substitution mutations. [2] [5] [3] [4]
Efficacy was evaluated in MARIPOSA (NCT04487080), a randomized, active-controlled, multicenter trial of 1074 participants with exon 19 deletion or exon 21 L858R substitution mutation-positive locally advanced or metastatic non-small cell lung cancer and no prior systemic therapy for advanced disease. [5] Participants were randomized (2:2:1) to receive lazertinib in combination with amivantamab, osimertinib monotherapy, or lazertinib monotherapy (an unapproved regimen for non-small cell lung cancer) until disease progression or unacceptable toxicity. [5]
Lazertinib was approved for medical use in the United States in August 2024. [5]
In November 2024, the Committee for Medicinal Products for Human Use of the European Medicines Agency adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Lazcluze, intended in combination with amivantamab, for the treatment of non-small cell lung cancer (NSCLC) with activating epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 L858R substitution mutations. [3] The applicant for this medicinal product is Janssen-Cilag International NV. [3] [12] Lazertinib was authorized for medical use in the European Union in January 2025. [3] [4]
Lazertinib is the international nonproprietary name. [13]
Lazertinib is sold under the brand name Lazcluze [2] [3] and in South Korea as Leclaza. [7]
