NEWARK, CA / ACCESSWIRE / November 9, 2023 / Protagonist Therapeutics (Nasdaq:PTGX) today announced it ranked in the top 3% of the 2023 Deloitte Technology Fast 500^TM, a list of the fastest-growing technology, media, telecommunications, life sciences, fintech and energy tech companies in North America. Life sciences and software companies dominated at the top of the Fast 500 this year; Protagonist joins Vir Biotechnology and Moderna among the top companies across all sectors.

This honor reflects the validation of our innovative peptide technology platform, the promise of peptide therapeutics, the dedication of our team and the strength of our partnerships. We intend to continue on this trajectory with the ultimate goal of bringing new medicines to address unmet needs in patients."

Paul Silverglate, vice chair, Deloitte LLP and U.S. technology sector leader, said, "Each year, we look forward to reviewing the progress and innovations of our Technology Fast 500 winners. This year is especially celebratory as we expand the number of winners to better represent just how many companies are developing new ideas to progress our society and the world, especially during a slow economy."
