Indicated for the treatment of adult and pediatric patients 12 years of age and older with advanced or metastatic thyroid cancer with a RET gene fusion, as detected by an FDA-approved test, who require systemic therapy and who are radioactive iodine-refractory (if radioactive iodine is appropriate)

Indicated for the treatment of adult patients with locally advanced or metastatic solid tumors with a RET gene fusion that have progressed on or following prior systemic treatment or who have no satisfactory alternative treatment options.

This summary is based on the review of two randomized controlled trial(s). ^[1-2]
In patients with rearranged during transfection (RET) fusion-positive non-small-cell lung cancer (NSCLC), selpercatinib demonstrated a median progression-free survival (PFS) of 24.8 months (95% confidence interval (CI), 16.9 to not estimable), compared to 11.2 months (95% CI, 8.8 to 16.8) for the control, with a hazard ratio (HR) for progression or death of 0.46 (95% CI, 0.31 to 0.70), P<0.001.
In patients with RET-mutant medullary thyroid cancer (MTC), selpercatinib significantly improved PFS with a hazard ratio for disease progression or death of 0.28 (95% CI, 0.16 to 0.48), P<0.001, and a 12-month PFS rate of 86.8% (95% CI, 79.8 to 91.6) compared to 65.7% (95% CI, 51.9 to 76.4) for the control group.
Selpercatinib achieved higher overall response rates in both NSCLC (84%, 95% CI, 76 to 90) and MTC (69.4%, 95% CI, 62.4 to 75.8) compared to control treatments.
In MTC patients, 38.9% of those treated with selpercatinib required dose reductions compared to 77.3% in the control group. Treatment discontinuation due to adverse events was 4.7% for selpercatinib versus 26.8% for the control.
For non-small-cell lung cancer (NSCLC), adverse events with selpercatinib were consistent with previous reports, but no detailed breakdown was provided.
The studies focused on patients with advanced RET fusion-positive NSCLC and RET-mutant MTC. In both populations, selpercatinib demonstrated significant improvements in progression-free survival, overall response rates, and treatment failure-free survival compared to control treatments.
