About PTI-428
PTI-428 is a first in class investigational CFTR amplifier for the treatment of CF in patients who are homozygous for the F508del mutation. PTI-428 is designed to increase the amount of newly synthesized cystic fibrosis transmembrane conductance regulator (CFTR) protein and to act synergistically with other CFTR modulators, such as correctors and potentiators. PTI-428 has received Fast Track, Orphan Drug and Breakthrough Therapy designations by the FDA.
PTI-428 is in development as an add-on therapy to approved CFTR modulator products such as Orkambi® and Symdeko(TM), and as part of PTI's proprietary once-a-day dosing triple combination regimen, which includes PTI-808, the Company's potentiator, and PTI-801, its corrector. The ongoing study of the triple combination received endorsement from the Therapeutics Development Network (TDN), the drug development arm of the Cystic Fibrosis Foundation (CFF), and PTI expects to report preliminary data from this study in the second half of 2018. In April, the TDN also endorsed Proteostasis' study protocol to investigate PTI-428 in CF patients on background Symdeko therapy. Proteostasis plans to initiate this Phase 2 study in the third quarter of 2018. Previously, PTI announced the results of a 28-day Phase 2 study in CF subjects on background Orkambi therapy, in which PTI-428 demonstrated mean absolute improvements in ppFEV(1) of 5.2 percentage points from baseline compared to placebo (p<0.05).
About PTI-801
PTI-801 is a third generation CFTR corrector, which is currently being studied in a 14-day trial in CF patients on background Orkambi treatment. PTI expects to report additional data from this study in the second quarter of 2018. In December, Proteostasis announced initial data from the first five subjects (four PTI-801 treated and one placebo) of the first dose level, once-a-day 100 mg of PTI-801. PTI-801 is also being studied in a double combination trial with PTI-808 and as part of PTI's proprietary triple combination.
About PTI-808
PTI-808 is the Company's novel CFTR potentiator, which is currently being evaluated as part of PTI's proprietary double (PTI-801 and PTI-808) and triple combination treatments. Proteostasis announced in December that it had completed PTI-808 safety and PK profiles from its SAD and MAD study in healthy volunteers. A total of 48 healthy volunteers had participated and completed the study of up to 300 mg of once-a-day, orally dosed PTI-808 in single and multiple dose cohorts. PTI-808 was found to be generally well tolerated.
