Slow moving turtles may help fight for a fast moving big human crisis


Our human being is facing a lot crises. No, not the border crisis Trump just declared. 🤠Certainly not any manufactured crisis that someone  is calling. 😲😲I’m talking about something health-related. If you are not aware of yet, one big crisis we are witnessing is the diabetes crisis. Here is the alarming stats from the government: According to the Centers for Disease Control and Prevention (CDC), 30.3 million people—or 9.4 % of the U.S. population—had diabetes in 2015, and in the same year, about 1.5 million new cases of diabetes were diagnosed among adults age 18 or older. The CDC also estimates that 33.9% of U.S. adults had prediabetes. The economic burden of diabetes is massive. The American Diabetes Association (ADA) estimates that the cost of diagnosed diabetes in the U.S. hit $327 billion in 2017, with reduced productivity costing another $90 billion (Diabetes Care 2018;41:917-928).(You can see more details in this report: Facing the Diabetes Crisis).


One of the most effective treatment is insulin, a protein that we normally should produce to balance the glucose levels but diabetic patients often lack, especially those with so-called type I diabetes. Although there are many other effective antidiabetic medications that have been invented in the past decades, insulin remains an unbeatable effective core therapy for this terrible life long disease. For those not in the medical field, the biggest drawback for insulin is the way how it must be used. It is a painful injection every day the patient has to do. If it is just a short term injection, it is not a big deal, right? But it is a life long routine patients have to endure. For years, scientists have been trying to develop a new formulation like a pill or inhalant that may relieve patients from the painful treatment but all fail. Why so difficult you may ask? Well, it is all boggled down to the nature of insulin, that is it is a protein. As a protein, it is a big molecule that cannot be simply absorbed by our intestine. Instead it must be digested and downgraded into small molecule pieces that can pass through the intestinal wall and therefore it becomes useless after being absorbed into the blood. For inhalation, actually there is an insulin inhalation product already approved by the FDA but unfortunately it has been a widely disappointment in terms of usage, primarily due to the fact that it is very difficult to control the blood level from inhalation. The insulin blood level is very critical as it can easily cause disaster if not well controlled such as dangerous hypoglycemia with too much insulin. If I’m not mistaken, this is the major issue for the inhalation insulin. So if there is any breakthrough that will allow easy intake of insulin without relying on injection, that could be revolutionary given the rampant crisis. I’m happy to say that we may see a glimpse of light now. Scientists are developing an oral insulin delivery system.  See below what was reported in Science with a genius idea that will basically still inject insulin but within the stomach. If successful, patients may get stable doses of insulin as the current skin injections but without pain.


The pill is about the size of a blueberry and contains a small needle made of insulin. Once it reaches the stomach, it adjusts its orientation to ensure contact with stomach tissue before injecting the medicine. In tests in rats and pigs, the drug successfully lowered blood sugar to levels similar to those seen with insulin injections. The team reported the results in Science.


Interestingly, this idea was inspired by tortoises actually. The key to success is to make sure the tiny needle can always position in such a way to make the injection directly into the stomach wall. Turtles are well known to able to turn around to position properly regardless what happens, even in an upside down position. That’s why scientists want to mimic for this new insulin delivery system. It looks promising at least in the animal testing. Of course it is still a long way to go before it can be finally proved effective in humans but I think the prospect is bright!


If indeed it proves to be successful, which company may benefit the most? Novo Nordisk (NVO), the company that sponsors the development of this technology. If you are not yet aware, NVO is a pure player for insulin development and actually I cannot think about any other well-established pharma that is so successful for decades but solely based on one product, insulin! That also speaks for the fact that how critical insulin is for this life long disease as the need is always there and growing as the crisis is deepening. NVO is a very well managed drug company and its business has been booming for decades. More attractively to me is the fact that NVO is also a great dividend growth stock. In the past two years though, NVO has apparently run against its bottleneck and its growth has been slowing down significantly. But I think it is temporary hiccup and great business can always find its way to turn challenges around. I have good faith in NVO for its long term. This new development of the innovative technology shows again how NVO is working hard to overcome the obstacles it is facing. If successful, it will be a great stride for it and greatly benefit the company while helping diabetic patients in a revolutionary way. Even if not, it will also trying to innovate in other ways to continue its mission to help fight for this human crisis.
