Insights

Lorlatinib effectively treats anaplastic lymphoma kinase-positive non-small cell lung cancer. This case suggests lorlatinib may trigger autoimmune thyroiditis, a condition that resolved after discontinuing the drug.

Area of Science:

  • Oncology
  • Immunology

Background:

  • Lorlatinib is an effective treatment for anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC).
  • The safety profile of lorlatinib, especially immune-related adverse events, requires further characterization.
