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.

Detirelix is a synthetic decapeptide containing five D-amino acids. It is a very potent Gonadotropin-releasing hormone (GnHR) antagonist. The acute effects of detirelix were consistent with peripheral vasodilation. Subchronic effects were associated with inhibition of pituitary gonadotropic and gonadal hormone secretion. As long-acting GnRH antagonist detirelix can rapidly suppress gonadotropin secretion, inhibit follicular development, and prevent ovulation. It can be used as luteolytic agent. A projected use is for the treatment of sex hormone-releasing diseases, as part of anticancer hormone therapy of sex-hormone-dependent tumors.

ABT-510 is an anti-angiogenesis compound that was under development by Abbott for the treatment of solid tumours, lymphoma and melanoma. It is a synthetic peptide that mimics the anti-angiogenic activity of the endogenous protein thrombospondin-1 (TSP-1). ABT-510 inhibits the actions of several pro-angiogenic growth factors important to tumor neovascularization; these pro-angiogenic growth factors include vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF)), hepatocyte growth factor (HGF), and interleukin 8 (IL-8).

N-acetylmannosamine (ManNAc), a hexosamine monosaccharide, is the first committed biological precursor of Neu5Ac. N-acetylmannosamine is being investigated as a potential treatment for GNE myopathy. N-acetylmannosamine has being reported to improve the cognitive function in aged animals. It has potential therapeutic application for cognitive dysfunction. N-acetylmannosamine is under investigation for GNE myopathy.

Lisavanbulin, also known as BAL-101553, a prodrug of the molecule BAL-27862 with potential antitumor activity. BAL-27862 binds to tubulin, prevents tubulin polymerization, destabilizes microtubules, arrests tumor cell proliferation, and induces cell death in cancer cells. Lisavanbulin participated in phase II clinical trials for the treatment of advanced solid tumors. Besides, the drug participates in a 1/2a clinical study in patients with recurrent glioblastoma and in patients with platinum-resistant or refractory ovarian cancer. In this study, will be characterized the safety and tolerability and to obtain efficacy data in these selected cancer types.
