Company Background

Thermalin Inc. is developing a pipeline of patent pending insulin analogs that address significant unmet needs in the rapidly growing insulin market ($17B today, $70B expected worldwide by 2030).  Founded on a portfolio of new insulin analogs invented by Dr. Michael Weiss, Chairman Emeritus of Biochemistry at Case Western Reserve Medical School and Director of Therapeutic Protein Institute, Thermalin’s focus is on advancing new rapid-acting and new long-acting insulins into the market.  Thermalin’s analogs are expected to address many problems associated with diabetes management by providing faster onset, lower cancer risk, reduced weight gain, reduced damage to insulin-producing cells, sustained release, and/or unrefrigerated stability/reduced fibrillation. By addressing multiple, clinically-relevant modalities, Thermalin expects to open new competitive dimensions in the marketplace. Upon clinical validation, these benefits should put Thermalin’s new insulins in an excellent, defensible position to compete for market share.
