Type 1 diabetes (T1D) is an autoimmune disease that permanently destroys beta cells of the pancreatic islet, which means that the body can no longer produce insulin. Over the last 90 years, insulin therapy has been evolving continuously, as at present, no other treatment can be offered to a patient who is newly diagnosed with T1D. A variety of insulin analogs with different times of action long-acting as well as short or rapid-acting analogs have been on the market for the past decade. In addition, many other developments were happening in parallel, such as glucose monitoring and significant advances in insulin delivery systems. The T1D market will approximately double over the forecast period, growing from $6.6 billion to $13.6 billion.This growth will be fueled by the significant increase in T1D prevalence as well as the uptake of the novel ultra-long-acting insulin analogs, novel ultra-rapid formulations of insulin analogs, and the adjunct therapies for T1D. The launches of these novel products will offset the dip in sales caused by the patent expiries of seven insulin products, and the consequent emergence of biosimilars.
