No. Here's where we are:
1- There are insulin pumps now that drip insulin at a constant rate into tissue, keeping blood sugar relatively even, and that also deliver a 'bolus' of insulin to take care of meals. The person has to estimate the carbs in each meal and decide how much insulin to have the pump deliver for each gram of carb. It is very complicated, and many people are unable to use it effectively.
2- There are pancreas transplants, which leave the person diabetes-free, but they must take a lot of anti-rejection drugs that can have nasty side effects, including bone loss .
3- An artificial pancreas is in the testing stage. It would sense your blood sugar and try to duplicate the dance of the liver and pancreas. It will be expensive and will probably not be available for several more years.
4- There is talk of 'immunotherapy', where doctors would harvest all of a person's immune cells, kill the adult ones that attack insulin-producing cells, keep the 'precursor cells' and reinject them into the body. This is a long shot, from what I am reading.
