01Mechanism of Action

Parameter
Adipotide
Survodutide
Primary target
Prohibitin-1 (PHB1) on adipose vasculature endotheliumHossen 2013
GLP-1 receptor and glucagon receptor (GCGR)Yathindra 2026Zimmermann 2026
Pathway
CKGGRAKDC domain binds PHB1 → Peptide internalisation → D(KLAKLAK)₂ mitochondrial membrane disruption
Central: CVOs → hypothalamic appetite regulation. Peripheral: GLP-1R → incretin effect; GCGR → hepatic lipid metabolism, energy expenditureZimmermann 2026Long 2026
Downstream effect
Endothelial apoptosis → Adipose vascular collapse → Adipocyte involution → Weight loss
Decreased energy intake, increased energy expenditure, improved glucose homeostasis, hepatic fat reductionZimmermann 2026Yathindra 2026
Feedback intact?
N/A — Direct apoptotic mechanism, non-hormonal
Origin
Synthetic bioconjugate: PHB1-targeting homing peptide + pro-apoptotic KLA sequence
Antibody development

05Administration Protocol

Parameter
Adipotide
Survodutide
1. Route
Intravenous injection (systemic) in preclinical models. No human protocols exist.
Specific reconstitution protocol not yet publicly disclosed. Follow manufacturer instructions upon approval.
2. Formulation
Bioconjugate peptide. May also be encapsulated in nanoparticles (prohibitin-targeted nanoparticle formulation, KLA-PTNP, showed superior efficacy vs. free bioconjugate in mice).Hossen 2013
Subcutaneous — abdomen, thigh, or upper arm. Rotate sites weekly to minimize injection site reactions.
3. Preclinical dosing
Low-dose systemic injection (exact dosing not specified in available abstract). Frequency and duration not detailed.Hossen 2013
Once weekly, same day each week. Can be administered at any time of day, with or without meals.
4. Storage
Not specified — likely requires peptide-grade lyophilised storage and reconstitution.
Store refrigerated (2–8 °C) until use. Do not freeze. Protect from light. Specific reconstituted storage duration pending labeling.
5. Needle
Subcutaneous injection with appropriate gauge needle (typically 27–31G). Use sterile technique.
