Delparantag is a novel, salicylamide-derived, small molecule. Delparantag is heptagonist. It acts as universal anticoagulation-reversing agent. Delparantag neutralized the antithrombotic, anticoagulant, and bleeding effects of heparins as effectively as protamine sulfate and may be slightly more efficacious against low-molecular-weight heparins (LMWHs). This agent was designed to restore coagulation by specifically binding to the pentasaccharide and disrupting unfractionated heparin and LMWH interaction with antithrombin. Delparantag has been shown to completely reverse the anticoagulant effects of heparin and normalize blood-clotting time in six human subjects in less than 10 minutes in a phase IB clinical trial. In clinical trial studies, safety was ascertained by blood pressure measurements and efficacy was determined by measuring blood clotting time (aPTT, Activated Partial Thromboplastin Time, or ACT, Activated Coagulation Time). Plasma half-life elimination of delparantag is between 3 and 5 min. Development was recently paused due to hypotension noted in the studies although this may be avoided with longer administration times and will require further investigation.

Elpamotide is an anti-angiogenic cancer vaccine. It is an HLA-A*24:02-restricted epitope peptide of vascular endothelial growth factor receptor 2 (VEGFR-2) (RFVPDGNRI) and induces cytotoxic T lymphocytes (CTLs) against VEGFR-2/KDR. OncoTherapy Science was developing elpamotide for the treatment of solid tumors.

alpha-MELANOTROPIN (also known as an alpha-melanocyte-stimulating hormone or alpha MSH) is an endogenous melanocortin 1-receptor agonist, which exclusively expressed in cells of the melanocytic lineage. alpha-MELANOTROPIN possesses anti-inflammatory properties and antagonizes proinflammatory mediators, including TNF-alpha, IL-6 and NO, and induces anti-inflammatory cytokine IL-10. alpha-MELANOTROPIN was studied in phase I clinical trial in patients with acute renal failure. In addition, this compound was assigned of orphan designation for the treatment of chronic beryllium disease.

Modimelanotide is a melanocortinergic peptide drug derived from α-melanocyte-stimulating hormone (α-MSH) which was under development for the treatment of acute kidney injury. Modimelanotide had promising preclinical data, and a Phase II trial in patients undergoing cardiopulmonary bypass surgery showed a reduced incidence of acute kidney injury in subjects that received Modimelanotide. However, a Phase IIb, multicenter study of Modimelanotide in patients with chronic kidney disease who underwent cardiopulmonary bypass surgery failed to show a significant reduction in the incidence of acute kidney injury in subjects who received the drug, both by serum creatinine measurements and by novel biomarkers of tubular injury.
