BioLineRx Ltd has developed BL-8040, a short peptide for the treatment of solid tumors, acute myeloid leukemia, or AML, and stem-cell mobilization for bone-marrow transplantation. BL-8040 acts as CXCR4 antagonist. CXCR4 is a chemokine receptor that is directly involved in tumor progression, angiogenesis, metastasis, and cell survival. In February 2019 US Food and Drug Administration (FDA) has granted Orphan Drug Designation to BL-8040, for the treatment of pancreatic cancer. Previously FDA had granted Orphan Drug Designation for the treatment of acute myeloid leukemia and stem-cell mobilization.

Biafungin (formerly SP 3025 or CD101), a highly stable echinocandin and an antifungal drug that was studied against panels of Candida and Aspergillus clinical isolates. Biafungin was involved in phase II clinical trials in the treatment of acute moderate to severe vulvovaginal candidiasis. Seachaid Pharmaceuticals invented this drug. Then Cidara Therapeutics acquired a worldwide exclusive license to develop and commercialize the drug.

Difelikefalin (Korsuva™) is a synthetic peptide agonist of the kappa opioid receptor being developed by Cara Therapeutics for the treatment of pruritus. In August 2021, intravenous difelikefalin was approved in the USA for the treatment of moderate-to-severe pruritus associated with chronic kidney disease (CKD) in adults undergoing haemodialysis. Difelikefalin selectively acts on kappa opioid receptors in peripheral tissues, which contribute to pruritis and nociception. The activation of opioid receptors in peripheral neurons and keratinocytes reduces afferent (sensory) impulses towards the central nervous system, decreasing pain signals. Activating kappa opioid receptors on immune cells, including monocytes and T lymphocytes, decreases the release of pro-inflammatory chemicals such as prostaglandins.
