Does Using Long Acting Insulin Increase Cancer Risk?

According to the FDA, five recent studies of a possible link between insulin glargine (marketed as Lantus long acting insulin) and the growth of cancerous cells have failed to shed more light on the subject. Calling the studies "inconclusive", the FDA said it was continuing to work with the long acting insulin manufacturer, Sanofi-Aventus, to determine whether there is an increased risk of cancer for users of insulin glargine.

The concerns arose because Lantus' ability to act as a long acting insulin arises from its prolonged interaction with the insulin-like growth factor-I receptor (IGF-IR). IGF-IR overactivity has been linked to many types of cancer. That begs the question - could long acting insulin glargine be associated with cancer because of its continual interfacing with IGF-IR?

While the debate about the possible cancer risk associated with long acting insulin continues, the American Diabetes Association, the American Association of Clinical Endocrinologists and two similar European governing bodies are reassuring insulin dependent diabetics that there is no need to change their insulin glargine treatment.

Enhanced Long Acting Insulin to Challenge Lantus

October 4th, 2011

(From Bloomberg Businessweek) Drugs to treat diabetes, mostly injectable insulin, have become a $34 billion annual business crowded with manufacturers of relatively similar products. Novo Nordisk wants to stand out from the pack. Following the example of consumer product companies, the Danish drugmaker is betting that it can add product enhancements to basic insulin and command higher prices in wealthier nations.

Explains Chief Executive Officer Lars Sørensen, pounding his desk for emphasis: "A country like the US ought to be able to offer people the most modern insulins and not giving them Third World insulins." Novo Nordisk, which gets half its $11.1 billion sales from insulin, this year is seeking U.S. and European regulatory approval for its newest treatment, degludec, in a bid to unseat Sanofi's Lantus as the world's best-selling diabetes medication.

Sørensen says degludec is "the fundamental part" of a strategy to boost Novo Nordisk's sales by shifting patients in developed nations from older, cheaper types of insulin that must be taken just before mealtimes to more expensive chemically altered versions that are absorbed more slowly and act longer.

Degludec's advantage is that it can be administered at any time, providing diabetes patients with greater flexibility, whereas Lantus insulin must be injected at the same time every day, although not necessarily at mealtimes. Trial results presented at a conference in Lisbon in September showed that degludec works as well as Lantus at controlling blood sugar.
