What is Cibinetide?
A tissue-protective peptide studied for neuropathy and inflammation with promising but limited clinical results.
This profile is educational. It organizes publicly discussed research context for Cibinetide and related naming aliases — it is not a treatment guide.
Proposed mechanism
Activates innate repair receptor (IRR), a heteromer of EPO receptor and CD131, promoting anti-inflammatory and cytoprotective signaling without erythropoietic effects.
Mechanism language on PepGuide describes how researchers discuss pathways. Proposed mechanisms can change as evidence evolves.
Current research notes
Human evidence grade: Limited human evidence
Preclinical evidence grade: Moderate human evidence
ARA-290 (cibinetide) was studied in sarcoidosis-associated neuropathy and diabetic neuropathy with mixed phase 2 results. Researchers highlight non-hematopoietic EPO pathway activation. Human evidence is limited to specific neuropathy contexts; not FDA approved.
Key uncertainties
- Regulatory path forward
- Efficacy in broader neuropathies
Research areas being studied
- Neuropathic pain
- Sarcoidosis neuropathy
- Tissue protection
Being studied for a topic is not the same as proven benefit in that topic. Prefer primary literature for study design, endpoints, and limitations.
Safety & side-effect notes
Reported or discussed adverse effects
- Generally well tolerated in trials
- Injection-site reactions
Additional risks & considerations
- Development setbacks in some indications
