LogicBio Reports Second Quarter 2019 Financial Results and Provides Business Updates

CAMBRIDGE, Mass., August 13, 2019 – LogicBio Therapeutics, Inc. (Nasdaq:LOGC) (LogicBio or the Company), a genome editing company focused on developing medicines to durably treat rare diseases in pediatric patients, today reported financial results and provided a corporate update for the second quarter ended June 30, 2019.

“Over this quarter, we continued to make steady progress advancing GeneRide^TM, our proprietary promoterless, nuclease-free genome editing platform with the potential to durably treat rare diseases in pediatric patients. We are committed to building a broad pipeline of product candidates to capture the full value of GeneRide, beginning with our lead product candidate, LB-001 for the treatment of methylmalonic acidemia (MMA), a rare and life-threatening pediatric disease,” said Fred Chereau, CEO of LogicBio. “We look forward to executing towards our upcoming milestones, including our plan to file an Investigational New Drug application for LB-001 in the fourth quarter of 2019.”

Business Highlights Include:

•

Rare Pediatric Disease Designation for LB-001 in July 2019. The FDA grants rare pediatric disease designation for serious and life-threatening diseases that primarily affect children through age 18 and affect fewer than 200,000 people in the United States. Separately, LB-001 was also granted orphan drug designation by the FDA in April 2019.

•

Closed $20 Million Secured Debt Facility with Oxford Finance LLC and Horizon Technology Finance Corporation in July 2019. Under the agreement, $10 million was drawn down at closing and $10 million will be available following the enrollment of the first patient in the Company’s Phase 1/2 clinical trial of LB-001.
