[12] Pralsetinib was approved for medical use in the United States in September 2020,[12][13][14][15][16][excessive citations] and in the European Union in November 2021.
[8] Pralsetinib is indicated for the treatment of adults with metastatic RET fusion-positive non-small cell lung cancer (NSCLC) as detected by an FDA approved test.
[12][15] Efficacy was investigated in a multicenter, open-label, multi-cohort clinical trial (ARROW, NCT03037385) with 220 participants aged 26-87 whose tumors had RET alterations.
[12][15] Identification of RET gene alterations was prospectively determined in local laboratories using either next generation sequencing, fluorescence in situ hybridization, or other tests.
[15] Efficacy for RET fusion-positive NSCLC was evaluated in 87 participants previously treated with platinum chemotherapy.
