In addition to the proprietary triplet study, Proteostasis is conducting studies exploring a proprietary doublet (PTI-808 and PTI-801), and separate studies of PTI-801 and PTI-428 with background SYMDEKO® (tezacaftor/ivacaftor and ivacaftor) therapy, in CF subjects. All four studies are on track to read out in the first quarter of 2019.
"We believe a comprehensive data set from our proprietary doublet and triplet studies will provide evidence of the individual contribution of each drug candidate to the overall activity of the combinations, supporting Phase 3 dose selection rationale," said Meenu Chhabra, President and Chief Executive Officer of Proteostasis. "In addition to our proprietary combinations, we remain as excited about our add-on portfolio, with both strategies reinforcing our commitment to expanding treatment options for CF patients. Given that the anticipated timing of these study readouts across this portfolio of programs remains Q1 2019, assuming positive results, we expect to be in a position to initiate Phase 3 studies within the next 12-18 months."
