  • 2. Cantor Fitzgerald analysts commented, "The Disclosure Section may be found on pages 43 – 45. We are initiating coverage of Proteostasis Therapeutics (PTI) with an Overweight rating and a 12- month price target of $21/share. Proteostasis is developing CFTR modulators for the treatment of cystic fibrosis. The company has a number of ongoing Phase 2 studies evaluating doublet and triplet proprietary drug combinations, with further studies assessing the drugs as add-on therapies to standard of care. In our view, cystic fibrosis is a well-understood disease that has received a magnitude of support from multiple CF foundations. We believe Vertex (Rated OW by Alethia Young) has ignited the engine with establishing proof of concept of this drug class, with three approved drugs." (11/6/2018)
  • 3. HC Wainwright analysts commented, "Our price target of $15 is based on a probability-adjusted $12 from PTI-428 in F508del CF (12% discount rate, 2% growth rate, in line with the expected discount and growth parameters of a development-stage company) + $3 in cash. Risks to our investment thesis and target price include: (1) failure in clinical studies; (2) failure to secure regulatory approval; and (3) a smaller than anticipated commercial opportunity due to market size, competition, and/or pricing.
