Hi Rayiner, you are spot on with your analysis

Hi Rayiner, you are spot on with your analysis. My name is Eric, and my non-profit, Project Insulin, is tackling this problem head-on as well. We are developing a biosimilar insulin and will distribute it directly to patients at cost. The drug development process is still expensive but much cheaper because of the Biologics Act that was passed in 2020. When going through the FDA approval process, biosimilar insulin makers don't have to do phase 2 trials, and their phase 1 & phase 3 are focused on interchangeability with the reference product rather than proving that insulin is a way to lower high blood sugars. Another obstacle, as you pointed out, is that there are few manufacturers who produce synthetic insulins. From what I've learned in my discussions with manufacturers is that many are transitioning their facilities to a focus on mRNA drug manufacturing. Therefore there is a limited set of manufacturers who don't make insulin but have the equipment/facilities for it (in the U.S.).

> I don't understand. My understanding of why insulin is so expensive: intellectual property laws are enforced by the government preventing businesses without that intellectual property to compete in the space. That’s not an accurate understanding of intellectual property specifically. Insulin isn’t like a pill, where once you have a chemical formula you can make millions of them very cheaply. It’s a biologic, an artificial hormone. Even leaving aside the patents, it’s very expensive to get approval for a generic biologic (called a biosimilar). That’s why there are few manufacturers of synthetic human insulin, even though that’s out of patent.

Hi Eric! I'm a T1D and so super interested in this space. Can you comment on whether it is the case that "modern" insulins (Lantus and Humalog/Novolog, in my case) are both covered by current patents, and also considerably better for patient outcomes (faster acting, more predictable -> lower A1c) than non-covered insulins? That is my understanding for why cheap, high quality insulins are not available, but I'd love to be informed if it is not the case! Thank you for your work in this area!

Don't have anything to add - just wanted to say thank you for sharing and for the work you are doing. Providing low cost insulin that is a substitute at the counter will literally change and save lives. I'm glad I share this pale blue dot with humans like you.

Hi Eric, my name is Francesco. In the last three years we industrialized a novel method for producing biosimilar insulin (in Italy). We are an international team and I really would like to contact you. Can you write to the email you find on my profile?

Hey Eric, somewhat tangential question -- why is it that seemingly all precursor manufacturing is done in China or India? Is it just a low-cost game or are regulations making it too expensive to do in the U.S. or something else?
