Motixafortide (Aphexda) vs Synthetic Secretin (ChiRhoStim)
An educational, source-based comparison of Motixafortide (Aphexda) and Synthetic Secretin (ChiRhoStim) — how each peptide works, what it's researched for, and what to know before going deeper.
CXCR4 antagonist peptide that mobilizes stem cells for autologous transplant in multiple myeloma.
A long-acting synthetic peptide antagonist of the CXCR4 chemokine receptor. Disrupts the CXCR4/CXCL12 axis anchoring hematopoietic stem cells in the bone marrow, releasing them into circulation for collection. Used with G-CSF.
- Stem cell mobilization for autologous transplant in multiple myeloma
- • FDA-approved September 2023.
- • Common side effects: injection-site reactions, flushing, pruritus.
- • Risk of hypersensitivity / anaphylactoid reactions.
27-amino-acid peptide used to stimulate pancreatic secretions for diagnosis.
Synthetic human secretin that stimulates pancreatic bicarbonate, fluid secretion, and gastrin release — used diagnostically for pancreatic function, gastrinoma evaluation, and ERCP facilitation.
- Pancreatic function testing
- Gastrinoma (Zollinger-Ellison) diagnosis
- ERCP facilitation
- • FDA-approved.
- • Single diagnostic dose; minimal adverse effects.
