PTI Announces Preliminary Clinical Data

As mentioned above Proteostasis Therapeutics is having a great start to the trading session in the pre-market hours this morning after releasing positive clinical data. In a press release issued early this morning, the company offered up positive preliminary results from three doublet cohorts of its ongoing Phase 1 clinical trial. The trial is assessing PTI-808 and PTI-801. The company also provided an enrollment update from the triplet, PTI-808, PTI-801, and PTI-428. These treatments are being assessed as an option for patients with cystic fibrosis.

In the release, PTI said that at the time of the data cut, 21 subjects were randomized and treated in the first three dose cohorts of the doublet combination or received placebo. PK results proved to be as expected and confirmed a once-daily dosing profile for both PTI-801 and PTI-808. The company also said that the compunds are showing to be safe and generally well tolerated.

PTI also said that a dose-dependent improvement in ppFEV1 and sweat chloride concentration was observed across all cohorts. For ppFEV1, a maximum and statistically significant increase from baseline to day 7 of +6.3% and at day 14 of +5.9% was reported in the 300mg dose cohort. In a statement, Carsten Schwarz, MD, Head of the Adult Cystic Fibrosis Centre, Lung-Transplantation Program and Endoscopy Unit in the Department of Pediatric Pneumology and Immunology at the  Charité, Berlin University Medical Center, had the following to offer:

Doublet combinations, the current standard of care for many CF patients, are the benchmark for current treatment in cystic fibrosis. These data are the first results seen using an entirely new CF doublet, compare favorably to standard of care, and demonstrate the potential of next-generation CFTR modulators to further improve outcomes in this disease… I look forward to results from the fourth dosing cohort and to understanding the potential of another novel combination, PTI-801, PTI-808 and PTI-428.
