Physico-chemical stability of co-formulation of PEGylated human amylin with insulin.

Since the discovery of amylin no combined formulation with insulin has been made available. Amylin or its triple proline analog pramlintide are not compatible in solution with insulin. The drug candidate hAmy-PEG5k is a novel monoPEGylated amylin derivative with improved physicochemical properties and retained similar pharmacological activity compared to free amylin and pramlintide.

BZ043, a novel long-acting amylin analog, reduces gastric emptying, food intake, glycemia and insulin requirement in streptozotocin-induced diabetic rats.

Amylin analogs are important adjunctive drugs in the treatment of diabetes mellitus. However, a dual therapy with insulin involves inconvenient multiple injections. Here we describe a novel n-terminal PEGylated human amylin analog - BZ043 - and its potential to improve the control of glycemia using lower doses of insulin.

IL-13 immunotoxin accelerates resolution of lung pathological changes triggered by silica particles in mice.

Instillation of silica into the lungs of rodents results in pathological changes that strongly mimic human silicosis, an occupational lung disease marked by restrictive airway obstruction, inflammation, and fibrosis. Because IL-13 is a pivotal proinflammatory and fibrogenic cytokine, we examined whether a recombinant immunotoxin comprised of human IL-13 and a mutated form of Pseudomonas exotoxin (IL-13-PE) might affect pathological features of experimental silicosis. Mice received a single intranasal instillation of silica particles and were treated with intranasal IL-13-PE every other day from days 21 to 27 postsilica.
