Proteostasis Therapeutics, Inc., a company developing novel therapeutics that regulate protein homeostasis to improve outcomes for patients with neurodegenerative and orphan diseases, announced today that two new senior executives have joined the Company's management team. Proteostasis has appointed David Weiner, M.D., as Chief Medical Officer and Markus Haeberlein, MSc, Ph.D., as Senior Vice President of Chemistry.

“Dave and Markus bring a wealth of research and development experience to our company and will play pivotal roles as we move our lead clinical candidates into IND filings in 2014 and 2015. I am pleased to welcome them to our management team,” commented Mark Enyedy, Chief Executive Officer. “Dave will formulate and execute the development and regulatory strategy for our current pipeline as well as identify potential in-licensing opportunities to support our overall corporate growth strategy. Markus will lead our efforts to identify and optimize leads that modulate key pathways within the Proteostasis Network to strengthen and diversify our pipeline.”

About Proteostasis Therapeutics

Proteostasis Therapeutics is developing disease-modifying therapeutics for orphan and neurodegenerative diseases. The Company's lead programs in cystic fibrosis (CF) and protein aggregation disorders such as Parkinson's disease modulate protein chaperone and proteasomal degradation pathways within the cell. These pathways are part of the cellular ‘quality control' machinery, called the protein homeostasis network or Proteostasis Network (PN) that regulates protein folding, trafficking, and clearance. By enhancing the function and capacity of the PN, the Company's product candidates correct for imbalances in the PN resulting from the cumulative effects of disease, genetic mutations, environmental factors, and aging.
