GELESIS HOLDINGS, INC.

Gelesis Holdings, Inc., trading under the SPAC ticker CPSR as Capstar Special Purpose Acquisition Corp, is a blank-check company sponsored by Capstar Special Purpose Acquisition Holdings LLC that completed its initial public offering in 2021. The vehicle targeted the healthcare and medical-device sector, ultimately pursuing a business combination with Gelesis, Inc., a Boston-based biotech developing superabsorbent hydrogel therapeutics for weight management. The November 2021 8-K filing reflects activity during the de-SPAC process as the parties advanced toward closing. The combined company, focused on commercializing the FDA-cleared Plenity platform, subsequently began trading as a public entity.
