Sebriplatin (also known as NK-121 or CI-973) is a platinum analog with antitumor activity. Sebriplatin participated in phase II clinical trials for the treatment of patients with metastatic breast cancer. However, the further development of this drug was discontinued.

Ramorelix is a glycosylated gonadoliberin antagonist patented by Hoechst A.-G. as an anticancer agent. In preclinical studies, a single injection of ramorelix microparticles inhibited tumor progression for only 14 days. This short action is due to a different release profile of the ramorelix microparticles and the different specific activities of peptides incorporated. In the preventive experiments, animals were treated 17 days after DMBA induction before tumor development. Treatment with buserelin implants every 56 days or with buserelin microparticles every 28 days and the treatment with ramorelix microparticles every 7 days prevented the development of tumors. Six weeks after the last injection of ramorelix microparticles a strong tumor progression was seen. There was a clear correlation between peptide release and tumor inhibition. The implants and the microparticles were well tolerated, no tissue reaction or side-effects of ramorelix were seen.

SER-100 (previously known as ZP120, Ac-RYYRWKKKKKKK-NH2) is a peripherally acting orphanin FQ/nociceptin (ORL-1) receptor agonist that is in development with Serodus Pharmaceuticals for the treatment of Isolated systolic hypertension. SER-100 is a peripherally acting, highly potent and selective NOP receptor partial agonist, which was developed by coupling a chain of six lysine residues to an existing NOP receptor partial agonist hexapeptide, Ac-RYYRWK-NH2 to improve meta-bolic stability. SER-100 has sodium-potassium-sparing aquaretic and anti-natriuretic activity. SER-100 exerts a chronic hypotensive and bradycardic effects in rodents, including models of systemic and pulmonary hypertension. SER-100 produces its cardiovascular effects, at least in part, by inhibition of cardiac and vascular sympathetic activity. In terms of clinical evaluation, SER-100 was originally assessed in a randomized, double-blind, placebo controlled Phase II trial as add-on therapy in patients with sub-acute decompensated chronic heart failure (NCT00283361); how-ever, the clinical development of the peptide for this indication was terminated prematurely due to significant hypotensive activity, primarily on systolic blood pressure (SBP). Nonetheless, as a result of this profound drop in SBP, SER-100 (10 mg, s.c., bid) was investigated in a randomized, placebo-controlled study in patients with treatment-resistant isolated systolic hypertension (NCT01987284) and found to produce a meaningful and long lasting drop in SBP(~7 mmHg) and diastolic (~4 mmHg) blood pressure (DBP),as well as being safe and well-tolerated. FDA has granted an Orphan Drug Designation for SER-100 in pulmonary arterial hypertension (PAH).

LATROMOTIDE is a synthetic peptide with antineoplastic activity. It consists of 10 amino acid corresponding to amino acid residues 66-75 of human kinesin-like protein KIF20A.
