Gelesis Holdings, Inc., listed under ticker CPSR, became a publicly traded company through its business combination with Capstar Special Purpose Acquisition Corp, sponsored by Capstar SPAC Sponsor LLC, which completed its IPO in 2021. Operating in the healthcare and medical device sector, Gelesis developed a superabsorbent hydrogel technology platform targeting weight management and metabolic health indications. The company entered Chapter 11 bankruptcy proceedings in early 2023, and its October 2023 Form 8-K filing reflects continued activity during that restructuring period, marking a challenging post-merger outcome for the de-SPAC transaction.
