GtoPdb Ligand ID: 9450

Synonyms: CCX-168 | CCX168 | Tavneos®
Approved drug PDB Ligand Immunopharmacology Ligand
avacopan is an approved drug (FDA (2021), EMA (2022))
Compound class: Synthetic organic
Comment: Avacopan is a small molecule, competitive and orally bioactive antagonist of human C5a1 receptor [1]. It was originally proposed as an alternative to steroid (glucocorticoid) therapy for ANCA-associated vasculitis [3,7]. The evidence confirming C5, C5a and the C5a receptor as anti-inflammatory and anti-cancer drug targets was reviewed by Horiuchi and Tsukamoto (2016) [2].

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
Avacopan (research code CCX168) was evaluated in clinical trials for efficacy in ANCA-associated vasculitis and C3 glomerulopathy. Phase 2 results in ANCA-associated vasculitis were reported in [4]. This study showed that avacopan safely and effectively replaced high dose glucocorticoid (prednisolone) therapy in patients with ANCA-associated vasculitis, which supported progression to Phase 3 trial.
The EMA granted orphan designations for avacopan as a treatment for granulomatosis with polyangiitis, microscopic polyangiitis (both 2014), and C3 glomerulopathy (2017).
Positive results from Phase 3 (ADVOCATE trial NCT02994927 [6]) led to FDA approval of avacopan as an adjunct (in combination with standard therapy) for the treatment of severe ANCA-associated vasculitis in October 2021.
