Tissue Protection
Erythropoietin innate repair receptor signalling
Selective activation of the tissue-protective erythropoietin receptor complex without clinically meaningful erythropoiesis.
Biological pathway
ARA-290 is designed to activate the innate repair receptor, a heteromeric complex associated with anti-inflammatory, cytoprotective and tissue-repair signalling.
Evidence summary
Small phase 2 studies in sarcoidosis and diabetic neuropathy report symptom and small-fibre signals, but confirmatory evidence is limited.
Limitations
The receptor model and clinical relevance remain under investigation; findings cannot be generalised to unregulated products.
