Retevmo 80 mg is the primary capsule strength for selpercatinib, used in the standard 160 mg twice-daily regimen for patients weighing 50 kg or more. This is the dose evaluated in the pivotal LIBRETTO-001 trial, where it demonstrated robust clinical responses across RET fusion-positive NSCLC, RET-mutant medullary thyroid cancer, and RET fusion-positive thyroid cancer. Each capsule meets strict oncology manufacturing standards. A confirmed RET gene alteration via approved companion diagnostic testing is required before prescribing.
At the 80 mg-based regimen, selpercatinib delivers its full clinical potential — blocking oncogenic RET signaling with high selectivity, achieving objective response rates of up to 84% in treatment-naive RET fusion-positive NSCLC patients in the LIBRETTO-001 trial. Activity is maintained across RET fusions and RET activating mutations. CNS penetrance provides intracranial efficacy for patients with brain metastases. Reduced off-target kinase inhibition means a more manageable tolerability profile compared to earlier multikinase inhibitors.
The recommended dose for patients weighing 50 kg or more is 160 mg twice daily — two 80 mg capsules per dose, with or without food. Total daily dose is 320 mg. Capsules must be swallowed whole. Dose modifications apply for strong CYP3A4 inhibitors or inducers, hepatic impairment, and specified adverse reactions. Concurrent use of acid-reducing agents should be managed per prescribing guidance. Treatment is initiated and managed by an oncology specialist throughout the course of therapy.
