In which countries is Selpercatinib approved?

Selpercatinib Overview

Mechanism of Action

Selpercatinib is a highly selective, potent receptor tyrosine kinase inhibitor specifically designed to target the RET (rearranged during transfection) oncogene. It binds to the active site of the RET kinase domain, inhibiting both wild‐type RET and mutated or fusion variants. This inhibition effectively blocks downstream signaling pathways that are normally responsible for tumor cell proliferation and survival. In both in vitro and in vivo studies, selpercatinib has demonstrated robust activity against RET‐activated cancer models including those driven by gene fusions and activating point mutations. Its distinctive design minimizes off‐target activity on other kinases, thereby reducing toxicity and allowing for more focused therapeutic action. This mechanism of action underpins its use in several RET‐altered malignancies.

Clinical Indications

Clinically, selpercatinib has been primarily developed and approved for the treatment of RET‐fusion–positive non–small‐cell lung cancer (NSCLC) and various thyroid cancers such as RET‐mutant medullary thyroid cancer (MTC) and RET‐fusion–positive thyroid cancers. In many clinical trials, the drug has shown high objective response rates and durable responses, even in patients with central nervous system (CNS) metastases. Select clinical studies have reported overall response rates exceeding 60–80%, with some patient cohorts achieving complete responses. The significant efficacy in multiple subtypes of RET‐altered cancers has established selpercatinib as a paradigm shift for targeting oncogenic alterations in solid tumors and has contributed to its global approval in various regions.

Regulatory Approval Process

General Approval Process for Oncology Drugs

Oncology drugs, especially those targeting specific molecular pathways, generally undergo a rigorous and multi‐phased approval process. Regulatory agencies worldwide require extensive preclinical data, followed by stepwise clinical trials—from Phase 1 safety assessments to Phase 2/3 evaluations of efficacy and dosing. In scenarios where the target is a well‐characterized oncogene driver and there is an urgent unmet medical need, regulatory bodies often provide accelerated or conditional approvals. Such expedited pathways allow promising drugs to reach patients sooner, subject to the requirement of continued post‐approval studies to confirm long‐term efficacy and safety. The global regulatory frameworks emphasize a risk–benefit evaluation. Agencies such as the FDA in the United States, EMA in Europe, and PMDA in Japan have instituted pathways like breakthrough therapy designation, priority review, and accelerated approval to fast‐track drugs that address high‐unmet medical needs. This process involves extensive interactions between sponsors and regulators, where data from pivotal clinical trials are supplemented by real‐world evidence and post‐marketing commitments.

Specific Considerations for Selpercatinib

For selpercatinib, the regulatory approval strategy was tailored to its targeted mechanism and robust clinical activity. The pivotal LIBRETTO-001 trial, an international, open-label, multicohort study evaluating selpercatinib in patients with RET-altered tumors, provided the foundation for multiple approvals. In the United States, the FDA granted accelerated approval in May 2020 based on impressive response rates and durable responses in patients with RET fusion–positive NSCLC, as well as in advanced thyroid cancers. Subsequent data from additional cohorts further solidified its benefit–risk profile. In Europe, the approval through the European Medicines Agency (EMA) reflected a similar commitment to innovation in oncology, with the drug approved under a traditional pathway following robust data from the LIBRETTO-001 trial. Specific regulatory submissions in Europe also included details of the formulation (capsule form) and dosing regimen, which align with the clinical trial evidence. In markets such as Japan and China, additional considerations such as ethnic differences in pharmacokinetics, local trial data, and conditional approvals were factored into the regulatory decisions. In Japan, the Pharmaceuticals and Medical Devices Agency (PMDA) approved selpercatinib after reviewing data provided by Eli Lilly Japan KK, while in China, the Drug Regulatory Review was conducted under a conditional marketing approval process to address the immediate need for targeted therapies in RET fusion–positive NSCLC. Furthermore, orphan drug designations and specific indications for subtypes of thyroid cancer have been granted in select regions such as Australia. The orphan drug designation in Australia reflects the rarity of conditions like medullary thyroid cancer and provides incentives for companies to supply these critical therapies.
