Motixafortide (Aphexda) vs Triptorelin (Trelstar)
An educational, source-based comparison of Motixafortide (Aphexda) and Triptorelin (Trelstar) — 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.
Decapeptide GnRH agonist that initially stimulates then desensitizes pituitary GnRH receptors, suppressing LH, FSH, and downstream gonadal steroid production after the initial flare.
- Advanced prostate cancer
- Central precocious puberty (international)
- Endometriosis (international)
- • FDA-approved.
- • Initial testosterone flare; consider antiandrogen pretreatment.
- • Hot flashes, bone density loss with chronic use.
