Pralsetinib is an orally administered, small-molecule, selective RET inhibitor approved for the treatment of RET non-small cell lung cancer (NSCLC).

ARROW A multi-cohort, open-label, Phase 1/2 study at 71 sites (community and academic cancer centers). Patients aged 18 years or older with locally advanced or metastatic solid tumors, including RET fusion-positive non-small cell tumors, were recruited. cell lung cancer, and Eastern Cooperative Oncology Group performance status was 0-2 (later restricted to 0-1 in a protocol amendment). In Phase 2, patients receive 400 mg of oral platinib once daily and may continue treatment until disease progression, intolerance, withdrawal of consent, or investigator decision. The primary endpoints of Phase 2 are overall response rate (as assessed by blinded independent central review according to Response Evaluation Criteria in Solid Tumors version 1) and safety. Tumor response was evaluated in patients with RETfusion-positive non-small cell lung cancer who had center-adjudicated baseline measurable disease and who received platinum-based chemotherapy or who did not receive treatment because they did not meet standard of care. This ongoing study is registered with ClinicalTrials.gov, NCT03037385At the time of the interim analysis, enrollment of treatment-naïve RET fusion-positive NSCLC patients was ongoing.

Survey results:In2017year3month17233namesR were recruited between 2020year5month22 Among patients with ETfusion-positive non-small cell lung cancer(data cutoff), 92 had previously received platinum-based chemotherapy,29 treatment-first patients received platinib before 7month11 in 2019(Efficacy recruitment cut-off);87 patients who had previously received treatment and 27 patients who received treatment for the first time were collectively determined to have baseline measurable disease. The overall response was recorded at 53 (61%; 95% CI 50-71 ),including5patients(6%)who had complete remission; and19 (70%;50-86), including 3cases(11%)complete remission. Among 233casesRETfusion-positive NSCLC, the common Grade 3 or worse treatment-related adverse event was neutropenia(43cases[18%], hypertension (26 [11%]), and anemia (24 [10%]).
