Where are all the new diabetes drugs? – STAT

s oncologists race forward with new treatments verging on science fiction and biotech companies press onwith drugs for once-hopeless rare disorders, one of the worlds most pervasive diseases looks like its been left behind.

There are few new drugs on the horizon for diabetes, which affects about 29 million Americans. Most of the treatments in late-stage development are simply improved versions of whats out there taken weekly versus daily, or orally instead of by injection.

So has pharma run out of ideas in diabetes?

Not exactly. But whether its ideas will ever get to market is another question. Theres plenty of promising science in the early stages of research. Available drugs, however, work pretty well. Given the cost of development and a high bar for approval, pharma can only afford to advance true-blue breakthroughs, and those are hard to come by.

There are unmet needs, but its going to take a really good drug, said Dr. John Buse, director of the Diabetes Center at the University of North Carolina, Chapel Hill. Its not like 10 years ago where you could market acarbose, a drug you have to take three times a day that makes you fart. Now that profile would never make it into Phase 2.

And the economics can be unforgiving. Oral insulin has long been considered a Holy Grail in diabetes research, potentially freeing patients from routine injections in favor of an easy-to-take pill. But late last year, Danish drug maker Novo Nordisk backed away from such a project not because it failed in clinical trials, but because developing it would be too expensive to get a sure return on investment.

That logic frustrates patients and their advocates.

My wish would be that people thinking like that would spend time with the people who face the challenges of Type 1 diabetes, said Derek Rapp, CEO of JDRF, which funds and advocates for research in the field.

But diabetes has become a tough and crowded market. Industry leaders Sanofi, Novo Nordisk, and Eli Lilly have all issued grim sales forecasts in recent years, as pricing pressure makes their past discoveries less and less lucrative.Novo Nordisks CEO abruptly decided to resign last year amid a surprise dip in projected revenue.

Clearly the bar has gone up, said Dr. Philip Larsen, Sanofis head of diabetes research. The larger companies are now in what you could call a thinking-outside-the box mode.

That means betting on early-stage efforts that could truly move the needle, albeit withhigh odds of failure.

Scientists at Sanofi, for instance, noted that gastric bypass surgery can have remarkable effects on Type 2 diabetes, even sending some patients into remission. Their question: Can that be replicated with a drug? Theyve got a drug, now in mid-stage development, that seeks to copy the cocktail of endocrine events that happens in the aftermath of surgery, Larsen said. The goal:create an injection that spares the need for a knife.

Drug makers are also at work on so-called smart insulin, which would switch on when blood glucose is too high and then harmlessly switch off once it had normalized, reducing the risk of hypoglycemia. Others are digging into the gut microbiome, a network of trillions of microbes, in hopes of finding a way to ameliorate diabetes.

We dont want to add new classes just to have new classes, said Dr. Ruth Gimeno, vice president of diabetes research at Eli Lilly. We want to really make a difference. Were giving ourselves a little more time rather than saying lets just fill the pipeline with incremental things.

And pharma has gradually widened its aperture to include novel technology, examining how wearable devices, glucose monitors, and advanced insulin pumps can work alongside drugs to improve patients lives.

There are some exciting and promising things that are being looked at, but I think the scope of diabetes management is getting a bit wider to be not strictly pharmaceuticals, said Dr. Robert Gabbay, chief medical officer of Harvard Universitys Joslin Diabetes Center. Devices are becoming increasingly important.

For some doctors, the key isnt more new products. Its education to teach themhow to use whats already on the market

Drugs called GLP-1 agonists, introduced more than a decade ago, have proved both to lower patients blood sugar and cut the risk of long-term cardiovascular problems. The same goes for SGLT2 inhibitors, introduced in 2013, which have been shown to reduce the risk of death by 32 percent for Type 2 diabetics.

And yet theyre not being widely used.

Thats in part because most primary care physicians dont know how to use them, said Dr. Athena Philis-Tsimikas, who leads the Scripps Whittier Diabetes Institute in California. The other issue is paperwork: Doctors have to go through a ridiculous number of steps to get patients health plans to cover those new drugs, Philis-Tsimikas said.

Its not like were desperate for something that is additionally innovative, she said. Were not using what we have.
