Delving into the Latest Updates on Cebix, Inc. with Synapse

Overview

OBJECTIVELack of C-peptide in type 1 diabetes may be an important contributing factor in the development of microvascular complications. Replacement of native C-peptide has been shown to exert a beneficial influence on peripheral nerve function in type 1 diabetes. The aim of this study was to evaluate the efficacy and safety of a long-acting C-peptide in subjects with type 1 diabetes and mild to moderate peripheral neuropathy.RESEARCH DESIGN AND METHODSA total of 250 patients with type 1 diabetes and peripheral neuropathy received long-acting (pegylated) C-peptide in weekly dosages of 0.8 mg (n = 71) or 2.4 mg (n = 73) or placebo (n = 106) for 52 weeks. Bilateral sural nerve conduction velocity (SNCV) and vibration perception threshold (VPT) on the great toe were measured on two occasions at baseline, at 26 weeks, and at 52 weeks. The modified Toronto Clinical Neuropathy Score (mTCNS) was used to grade the peripheral neuropathy.RESULTSPlasma C-peptide rose during the study to 1.8–2.2 nmol/L (low dose) and to 5.6–6.8 nmol/L (high dose). After 52 weeks, SNCV had increased by 1.0 ± 0.24 m/s (P < 0.001 within group) in patients receiving C-peptide (combined groups), but the corresponding value for the placebo group was 1.2 ± 0.29 m/s. Compared with basal, VPT had improved by 25% after 52 weeks of C-peptide therapy (Δ for combined C-peptide groups: −4.5 ± 1.0 μm, placebo group: −0.1 ± 0.9 μm; P < 0.001). mTCNS was unchanged during the study.CONCLUSIONSOnce-weekly subcutaneous administration of long-acting C-peptide for 52 weeks did not improve SNCV, other electrophysiological variables, or mTCNS but resulted in marked improvement of VPT compared with placebo.

C-peptide is formed in the biosynthesis of insulin and is therefore deficient in patients with type 1 diabetes mellitus. A pegylated form of human synthetic C-peptide (CBX129801) has been developed to extend the half-life of the native peptide and is undergoing clinical investigation as replacement therapy to treat diabetic peripheral neuropathy. This monkey study was conducted to evaluate the toxicity of CBX129801 with weekly subcutaneous dosing for 39 weeks at dose levels of 0 (vehicle), 0.4, 1.33, and 4.0 mg/kg/wk. No systemic adverse effects were observed at any dose with maximal CBX129801 plasma concentrations of 735 to 1050 nmol/L during the dosing period (physiological range is 1-3 nmol/L). CBX129801-related effects were limited to minimal macrophagic vacuolization at the injection sites and in the associated draining (axillary) lymph nodes; these local effects largely resolved by the end of a 7-week recovery period. No systemic macrophagic vacuolization was observed. Additionally, there was no histological evidence for plaque formation in the major arteries of these nondiabetic animals.
