Arcturus Therapeutics to Receive Up to $3 Million from Cystic Fibrosis Foundation Therapeutics to Advance a Novel LUNAR-Formulated mRNA CFTR Therapeutic

SAN DIEGO, May 30, 2017 /PRNewswire/ — Arcturus Therapeutics, Inc. (“Arcturus” or the “Company”), a leading RNA medicines company, today announced that it has entered into a research agreement with Cystic Fibrosis Foundation Therapeutics Inc. (CFFT), the nonprofit drug discovery and development affiliate of the Cystic Fibrosis Foundation in which CFFT will pay up to $3 million to advance LUNAR-CF, a novel messenger RNA (mRNA) therapeutic formulated with Arcturus’ LUNAR™ delivery technology.

“Arcturus is developing a potentially transformative broad-spectrum mRNA therapeutic. If successful, it has the potential to treat all CF patients – more than 1,700 different genetic variations of the disease,” said Joseph E. Payne, President and CEO of Arcturus Therapeutics. “With the financial support from CFFT, we are now positioned to accelerate the development of our CF program and expand our LUNAR™ platform to include pulmonary delivery of nucleic acids.”

The two-year agreement will support discovery and development of mRNA therapeutics that aim to enable cells of CF patients to restore the function of their cystic fibrosis transmembrane conductance regulator, or CFTR, gene in their lungs. Arcturus’ LUNAR™ delivery system will be advanced and optimized for pulmonary administration to allow for the development of novel nucleic acid based therapeutics for a variety of respiratory diseases.
