Edratide (hCDR1 or TV-4710) is a peptide based on the sequences of the complementarity determining region (CDR) 1 of monoclonal anti-DNA antibody. The capacity of the peptide to bind to major histocompatibility complex class II molecules correlated with the proliferative responses. Edratide is being developed for the treatment of SLE (Systemic Lupus Erythematosus). Edratide ameliorates the SLE-related autoimmune process by specific upstream immunomodulation through the generation of regulatory T cells.

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.

Oxeclosporin (previously known as SDZ IMM 125 and now called as tigderimus) was developed as an immunosuppressive drug. It was shown that the drug possessed apoptotic activity via induction of uptake of extracellular calcium. The increased intracellular calcium might directly cause apoptosis by increasing the caspase-3 activity. Oxeclosporin was studied in clinical trials in patients with severe psoriasis. In addition, it was used for the treatment of rheumatoid arthritis and transplant rejection. However, all these studies were discontinued. Besides, oxeclosporin is participating in phase II trials in Europe for the treatment of asthma and in Switzerland for the treatment of cancer. However, information about the further development of this drug is not available.

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.
