New pill can deliver insulin through the stomach

About the size of a blueberry, the capsule contains a small needle made of compressed insulin, which is injected after the capsule reaches the stomach. In tests in animals, the researchers showed that they could deliver enough insulin to lower blood sugar to levels comparable to those produced by injections given through skin. They also demonstrated that the device can be adapted to deliver other protein drugs.

[...] Giovanni Traverso, an assistant professor at Brigham and Women's Hospital, Harvard Medical School, and a visiting scientist in MIT's Department of Mechanical Engineering, where he is starting as a faculty member in 2019, is also a senior author of the study. The first author of the paper, which appears in the February 8 issue of Science, is MIT graduate student Alex Abramson. The research team also includes scientists from the pharmaceutical company Novo Nordisk.

[...] Several years ago, Traverso, Langer, and their colleagues developed a pill coated with many tiny needles that could be used to inject drugs into the lining of the stomach or the small intestine. For the new capsule, the researchers changed the design to have just one needle, allowing them to avoid injecting drugs into the interior of the stomach, where they would be broken down by stomach acids before having any effect.

The tip of the needle is made of nearly 100 percent compressed, freeze-dried insulin, using the same process used to form tablets of medicine. The shaft of the needle, which does not enter the stomach wall, is made from another biodegradable material.

Within the capsule, the needle is attached to a compressed spring that is held in place by a disk made of sugar. When the capsule is swallowed, water in the stomach dissolves the sugar disk, releasing the spring and injecting the needle into the stomach wall.

    Take it on an empty stomach, preferable 15' before the meak, otherwise the probability to inject it into the stomach lining goes too low.
    Meaning: take it when your blood sugar level is the lowest. What can go wrong?

      Swallow a needle. That sounds really super safe, and super smart. Is the needle biodegradable, thus disappears via digestion after use? Or, does that little thingie pass through your intestines, then pop out the other end? Hmmmmm - wonder what the Sani-Can guys are going to think of that.

      I've lived with diabetics all my life. This sounds kinda cool, in that daily injections are obviously a pain in the ass.

      Maybe they should take another look at this idea. Insulin is broken down in the stomach, which is why people can't just swallow some insulin. But, what about the intestines? Put the stuff in a time-release capsule, that doesn't dissolve until arrival in the intestine? I suppose it's hard to figure out how to make that happen reliably. But, we do have all kinds of new technology, right? What we need seems to be a capsule that doesn't dissolve in stomach acid, but maybe the acid acts a catalyst. The capsule needs to dissolve when the environment becomes less acid, right?

      As near as I can tell, any insulin that reaches the intestine will be absorbed. No needles at all, if they can delay the capsule dissolving long enough.

        From the description, it's a tiny needle made of insulin that breaks off and dissolves. Sounds like the volume of insulin you need is really small.
        Given how fast it heals, and the high blood flow in the area, has anyone ever experimented with insulin injections under the tongue?

    The researchers — at M.I.T., Harvard and Novo Nordisk, the pharmaceutical company — hope to start testing Soma [self-orienting millimeter-scale applicator] in humans in three years.

    What kind of drugs are they loading this thing up with again?

    The innovation in Doyle’s research is that they have found a way to attach the insulin to vitamin B-12. The vitamin protects the insulin as it journeys through the gastrointestinal tract in a "Trojan horse" strategy.

    No undigestible bits there - sounds like a great idea!

    releasing the spring and injecting the needle into the stomach wall.

    This has to be accounted for somehow, but....What happens if the needle is pointed at the center of the stomach? Doesn't happen to hit a wall when the spring pushes it out?

    At that point isn't it just like any other insulin pill that doesn't work getting dissolved by stomach acid?

    This is reminiscent of Monty Python's spring surprise [youtube.com].

    I suppose this could be grounds for not granting them a patent.
