The company operates in the healthcare and pharmaceutical market, targeting patients with CF, particularly those with the F508del mutation. Proteostasis employs a business model centered around research and development, advancing its proprietary CFTR modulators through clinical trials. The company generates revenue through partnerships, grants, and potential future sales of its investigational drugs. Proteostasis is currently conducting the CHOICES trial, utilizing ex vivo screening of patient-derived organoids to identify responsive patients. Their triple combination therapy includes posenacaftor (a corrector), dirocaftor (a potentiator), and nesolicaftor (an amplifier), showing promising results in Phase 2 trials. The company aims to further develop and commercialize these therapies to improve the quality of life for CF patients.
