Motixafortide (Aphexda) vs Plecanatide (Trulance)
An educational, source-based comparison of Motixafortide (Aphexda) and Plecanatide (Trulance) — 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.
Synthetic analog of human uroguanylin that activates guanylate cyclase-C in a pH-dependent manner, increasing intestinal fluid secretion and transit.
- Chronic idiopathic constipation
- IBS-C
- • FDA-approved.
- • Diarrhea most common adverse event.

Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
|---|---|---|---|---|
| Motixafortide (Aphexda) | GENESIS phase 3 trial of motixafortide + G-CSF | Nature Medicine | 2023 | Higher proportion of patients collected ≥6×10^6 CD34+ cells/kg in ≤2 apheresis sessions vs G-CSF alone. |
| Plecanatide (Trulance) | Plecanatide phase 3 | American Journal of Gastroenterology | 2017 | Significantly improved complete spontaneous bowel movements vs placebo. |
