Halogenated Insulin: a fast-acting, ultra stable analog.
DESCRIPTION (provided by applicant): A Phase 1 SBIR program of pre-clinical development is proposed focusing on a novel rapid-acting insulin analog for the treatment of diabetes mellitus. Designated Insulin-Cl, our product is a derivative of insulin lispro
(the active component of HumalogTM) containing a single chloro-substitution within the aromatic ring of a conserved phenylalanine in the B-chain (PheB24). Insulin-Cl retains the interchange of residues B28 and B29 (substitutions ProB28 .Lys and LysB29.Pro
) that confers upon HumalogTM its rapid absorption following subcutaneous injection. Insulin-Cl offers to patients the potential advantages of (i) greater shelf life and stability to degradation at temperatures above room temperature; and (ii) possible for
mulation as a zinc-free solution to provide ultra- rapid absorption. Current meal-time insulin analogs such as HumalogTM and NovalogTM are less stable than human insulin and must be formulated as zinc insulin hexamers; as a consequence, absorption is in pr
inciple not as rapid as could be provided by a zinc-free formulation. Ultra-rapid absorption of Insulin-Cl may offer added patient convenience and also enhanced safety in closed-loop smart pumps coupled to glucose sensors. We seek to test candidate formu
lations of Insulin-Cl and to assess its in vivo potency and pharmacokinetics in animal models. Insulin-Cl was invented at Case Western Reserve University and is being developed under license to Thermalin Diabetes, Inc. The principal investigator, who bring
s to this application four decades of experience in pharmacetical studies of insulin formulations, was co-inventor of insulin lispro. PUBLIC HEALTH RELEVANCE: Diabetes is an increasingly prevalent disease in the developed and developing worlds; pati
ents seek greater convenience, improved glycemic control, and fewer adverse side-effects, all of which result in greater compliance and lower healthcare costs. This project will complete pre- clinical development of Insulin-Cl, a potentially ultra-stable a
nd ultra-rapid acting insulin analog which could conveniently be stored without refrigeration and taken closer to meal time and could cause less post-meal glucose deficiency.
