Approved drug
selpercatinib is an approved drug (FDA (2020), EMA (2021))
Compound class: Synthetic organic
Comment: Selpercatinib (LOXO-292) is a potent, selective and orally bioavailable ATP-competitive RET kinase inhibitor that was developed by Loxo Oncology. It inhibits wild-type RET, RET fusions,and RET carrying activating mutations and acquired resistance mutations [5]. This reference by Subbiah et al. contains preclinical and proof-of-concept data for LOXO-292. This compound was rationally designed to offer a novel therapeutic option for heavily pretreated, multikinase inhibitor-experienced patients whose tumours carry diverse RET alterations.

Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the CDK toolkit. All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.

Summary of Clinical Use Click here for help
LOXO-292 was advanced to clinical evaluation in patients with RET fusion-positive solid tumours. Click here to link to ClinicalTrials.gov's full list of LOXO-292/selpercatinib studies. Eli Lilly's New Drug Application for selpercatinib (for use in certain RET-fusion positive tumours) received FDA priority review, based on positive outcome data from the LIBRETTO-001 Phase 1/2 trial NCT03157128 [11]. In May 2020, this led to accelerated approval as a treatment for RET-fusion positive NSCLC or advanced/metastatic RET-mutant medullary thyroid cancer (MTC) [2]. More advanced trials are ongoing.
