Advancements and Technologies Driving Peptide Drug Design and Development Simplifying Progress Advancements and Technologies Driving Peptide Drug Design and Development Peptides are small intrinsic signaling molecules associated with numerous physiological functions. Since the introduction of insulin in the clinic in the 1920s, and the advent of peptide synthesis in the 1950s, dozens of therapeutic peptides have been developed. Peptides offer several advantages over other therapeutics, and ongoing research and development is aimed at enhancing their stability and efficacy. Advantages Challenges Discovery and Development ▪ high selectivity and potency ▪ chemical and physical ▪ new peptides and protein instability fragments ▪ safety and tolerability hydrolysis and

  • PARSABIV (Etelcalcetide) RATIONALE for INCLUSION IN
    PARSABIV (etelcalcetide) RATIONALE FOR INCLUSION IN PA PROGRAM Background Parsabiv (etelcalcetide) is a calcimimetic agent that increases the sensitivity of the calcium-sensing receptor to activation by extracellular calcium. These calcium-sensing receptors are on the parathyroid hormone gland and are the principal regulators of PTH (parathyroid hormone) synthesis and secretion. By increasing the sensitivity of the calcium sensing receptors, a reduction in PTH secretion is achieved. Reductions in PTH are associated with a decrease in bone turnover and bone fibrosis in patients with CKD (chronic kidney disease) on hemodialysis and uncontrolled secondary hyperparathyroidism (HPT) (1). Regulatory Status FDA approved indication: Parsabiv is a calcium-sensing receptor agonist indicated for treatment of secondary hyperparathyroidism (HPT) in adult patients with chronic kidney disease (CKD) on hemodialysis (1). Limitation of Use: Parsabiv has not been studied in adult patients with parathyroid carcinoma, primary hyperparathyroidism, or with CKD who are not on hemodialysis and is not recommended for use in these populations (1). Initial treatment with Parsabiv is contraindicated if serum calcium is less than the lower limit of the normal range. Life threatening events and fatal outcomes were reported due to hypocalcemia. Hypocalcemia can prolong QT interval, lower the threshold for seizures, and cause hypotension, worsening heart failure, and/or arrhythmia. Monitor serum calcium carefully for the occurrence of hypocalcemia during treatment. Once the maintenance dose has been established, serum calcium should be measured monthly for patients with secondary hyperparathyroidism with CKD on hemodialysis (1). In patients with secondary hyperparathyroidism with chronic kidney disease who are on hemodialysis, serum calcium should be measured within 1 week of starting Parsabiv, and intact parathyroid hormone (iPTH) should be measured 4 weeks after initiation or dose adjustment of Parsabiv (1).

  • Efficacy and Safety of Elcatonin in Postmenopausal Women with Osteoporosis: a Systematic Review with Network Meta-Analysis of Randomized Clinical Trials
    Osteoporosis International (2019) 30:1723–1732 https://doi.org/10.1007/s00198-019-04997-6 REVIEW Efficacy and safety of elcatonin in postmenopausal women with osteoporosis: a systematic review with network meta-analysis of randomized clinical trials W.-C. Chen1,2 & E.-Y. Lin3 & Y.-N. Kang1,4 Received: 20 November 2018 /Accepted: 21 April 2019 /Published online: 1 May 2019 # International Osteoporosis Foundation and National Osteoporosis Foundation 2019 Abstract Summary The present systematic review aimed to evaluate bone mineral density (BMD) change and complication rates of elcatonin on treating postmenopausal osteoporosis. The result confirmed efficacy of elcatonin and safety in combination thera- pies of elcatonin (C-E). Introduction Postmenopausal osteoporosis is an important issue in global aging trends. One treatment of osteoporosis is elcatonin, a kind of calcitonin. However, it has been challenged for long time because of safety. Many trials investigated on this topic, but they were designed differently. Those designs can be categorized in monotherapy of elcatonin (M-E) and C-E. Unfortunately, no synthesized evidence dealt this topic. Methods This study systematically identified target trials from six important databases and only included randomized controlled trial for synthesis. Two investigators assessed quality of eligible trials using the Cochrane Risk of Bias Tool, and they indepen- dently extracted data. Network meta-analysis performed Peto odds ratio (POR, used for dealing with zero cell) or weighted mean difference (WMD, for continuous data) with 95% confidence intervals (CI) and consistency H. Results Sixteen trials recruiting 2754 women with postmenopausal osteoporosis were included in our study. Elcatonin therapies and non-elcatonin medications had comparable fracture rates and bone mineral density change.

  • 1 Advances in Therapeutic Peptides Targeting G Protein-Coupled
    Advances in therapeutic peptides targeting G protein-coupled receptors Anthony P. Davenport1Ϯ Conor C.G. Scully2Ϯ, Chris de Graaf2, Alastair J. H. Brown2 and Janet J. Maguire1 1Experimental Medicine and Immunotherapeutics, Addenbrooke’s Hospital, University of Cambridge, CB2 0QQ, UK 2Sosei Heptares, Granta Park, Cambridge, CB21 6DG, UK. Ϯ Contributed equally Correspondence to Anthony P. Davenport email: [email protected] Abstract Dysregulation of peptide-activated pathways causes a range of diseases, fostering the discovery and clinical development of peptide drugs. Many endogenous peptides activate G protein-coupled receptors (GPCRs) — nearly fifty GPCR peptide drugs have been approved to date, most of them for metabolic disease or oncology, and more than 10 potentially first- in-class peptide therapeutics are in the pipeline. The majority of existing peptide therapeutics are agonists, which reflects the currently dominant strategy of modifying the endogenous peptide sequence of ligands for peptide-binding GPCRs. Increasingly, novel strategies are being employed to develop both agonists and antagonists, and both to introduce chemical novelty and improve drug-like properties. Pharmacodynamic improvements are evolving to bias ligands to activate specific downstream signalling pathways in order to optimise efficacy and reduce side effects. In pharmacokinetics, modifications that increase plasma-half life have been revolutionary. Here, we discuss the current status of peptide drugs targeting GPCRs, with a focus on evolving strategies to improve pharmacokinetic and pharmacodynamic properties. Introduction G protein-coupled receptors (GPCRs) mediate a wide range of signalling processes and are targeted by one third of drugs in clinical use1. Although most GPCR-targeting therapeutics are small molecules2, the endogenous ligands for many GPCRs are peptides (comprising 50 or fewer amino acids), which suggests that this class of molecule could be therapeutically useful.
