A new nanomedicine formulation method that uses the active pharmaceutical ingredient (API) as a scaffold rather than a separate matrix is a big breakthrough for biopharmaceutical manufacturers, says the team behind controlled-release insulin.<\/p>

The concept of nanomedicine\u2014the use of nanoscale technologies to create new dosage forms with improved characteristics\u2014has been around for a\u00a0century<\/a>. In most nano formulations the API is loaded onto an inert, non-functional material made of lipids or biodegradable polymers.<\/p>

In the small molecule space several nano-drug formulations are already on pharmacy shelves and more are in the pipeline.<\/p><\/blockquote>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The approach has also been used to develop nano-formulations versions of\u00a0biopharmaceuticals<\/a>. However, says Andrew Urquhart, PhD, from the Technical University of Denmark, the reliance on matrices has been a challenge.<\/p>

\u201cWhere there is matrix there cannot be drug and vice versa. If you are trying to load a biopharmaceutical, which frequently has a large molecular weight, then this means that the biopharmaceutical takes up more space than, say, a small molecule drug. This in turn means that we load less of the biopharmaceutical into a matrix,\u201d explains Urquhart.<\/p>

The approach, detailed in a paper in the International Journal of Biological Macromolecules,is based on the creation of so called \u201cprotein nanoclusters.\u201d<\/p>

\u201cWith protein nanoclusters we are maximizing the biopharmaceutical loading by eliminating the need for an inert matrix. This in turn allows a higher dose of a biopharmaceutical which could reduce the number of doses required,\u201d continues Urquhart.<\/p>

The team used insulin to develop the process, with the first stage being to cluster protein molecules into nano-sized spheres.<\/p>

\u201cIn this research we developed a methodology that linked insulins into small repeating units (oligomers of 2\u20135 insulins in water),\u201d says Urquhart. This involved chemically linking insulins in a manner that was reversible in the body, in other words, when the drug is administered the linkers begin to cleave.<\/p>

\u201cThen we force these insulin units to precipitate by introducing a small quantity of water miscible organic solvent which can be easily removed before any biological work. By controlling the rate of organic solvent addition we can control the size of the insulin nanocluster and we use the point where the solution becomes turbid.\u201d<\/p>

The resulting formulations show significant promise for the production of patient-friendly treatments for people with type 2 diabetes, notes Urquhart.<\/p>

\u201cInsulin nanoclusters had a lower potency than free insulin but a significant increase in therapeutic duration and allowed a large concentration of insulin to be administered without apparent toxicity. This last point is of potential interest in the case of patients with insulin resistance as a reduced number of administrations combined with a higher injection dose of insulin may help treat these patients.\u201d<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

And, looking beyond insulin, the nanocluster approach could be used to formulate other large molecule protein therapeutics and antibodies, according to Urquhart.<\/p>

\u201cAny therapeutic protein has the potential to be clustered as nanoclusters,\u201d he points out. We are still at an early stage in this emerging field and so there may be beneficial protein physicochemical properties for nano-clustering that we will discover as research continues.<\/p>

\u201cIt is also worth highlighting that in our biology, we have proteins that cluster into complex intracellular machinery that appear to assemble and disassemble in a controllable fashion. This last aspect indicates that protein clustering is flexible and controllable but will require significant study if we are to approach the level of control that our cells achieve.\u201d<\/p>

Urquhart and his colleagues have\u00a0previously<\/a>\u00a0developed nanocluster formulations of large molecule drugs for the treatment of neurodegenerative diseases of the retina.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
