A
grade
HMB supplementation combined with high-intensity functional exercise supports aerobic capacity but not strength in trained and untrained males: a randomized controlled trial.
PT-141 (Bremelanotide) · Journal of the International Society of Sports Nutrition · 2026 · RCT · n=90
HMB supplementation at 90 mg/kg FFM/day improves aerobic capacity in trained individuals but not strength, with limited effects in untrained individuals.
VO2MAX increased with HMB in TR, p=0.024.
B
grade
Risk stratification for in-hospital mortality in sepsis-associated acute kidney injury patients receiving continuous renal replacement therapy: an interpretable, externally validated machine learning study.
PT-141 (Bremelanotide) · Renal failure · 2026 · Observational
The gradient boosting machine model achieved an AUC of 0.890 for predicting in-hospital mortality in SA-AKI patients on CRRT, but its clinical utility may be limited by the study's retrospective design.
AUC of 0.890 in training cohort, n=1217.
D
grade
Comprehensive characterization of bremelanotide acetate and its degradants by LC-HRMS/MS and predicting epimerization through computational modelling.
PT-141 (Bremelanotide) · Analytical methods : advancing methods and applications · 2026
Bremelanotide showed lower degradation under acidic conditions and significant susceptibility to oxidative conditions, with eight degradation products identified.
Coefficient of determination (r²) of 0.9993 over the concentration range of 25-150 µg mL-1.
C
grade
Incorporation of Three Extracyclic Arginine Residues into a Melanocortin Macrocyclic Agonist (c[Pro-His-DPhe-Arg-Trp-Dap-Lys(Arg-Arg-Arg-Ac)-DPro]) Decreases Food Intake When Administered Intrathecally or Subcutaneously Compared to a Macrocyclic Ligand Lacking Extracyclic Arginine Residues (c[Pro-His-DPhe-Arg-Trp-Dap-Ala-DPro)].
PT-141 (Bremelanotide) · ACS pharmacology & translational science · 2024 · Preclinical · n=30
The study suggests that adding extracyclic arginine residues to melanocortin peptides may improve their ability to reduce food intake in mice, but the clinical implications for humans are not established.
Not reported in abstract.
