WALTHAM, Mass., March 10, 2022 (GLOBE NEWSWIRE) -- Dyne Therapeutics, Inc. (Nasdaq: DYN), a muscle disease company focused on advancing innovative life-transforming therapeutics for people living with genetically driven diseases, today reported financial results for the fourth quarter and full year 2021 and recent business highlights.

“In 2021 we made significant achievements throughout the business. We generated platform-validating preclinical data across our programs, including demonstrating sustained knockdown of toxic nuclear DMPK RNA and correction of splicing in DM1 and robust exon skipping and dystrophin expression in DMD. We also submitted our first IND for DYNE-251 in DMD in the fourth quarter, further strengthened our leadership team with multiple key hires, and completed a $168 million financing at the start of the year, extending our cash runway into the second half of 2024,” said Joshua Brumm, president and chief executive officer of Dyne. “We begin 2022 laser focused on advancing our programs into the clinic. We are on track to submit our response to the FDA for our DYNE-251 IND in DMD in the second quarter. In addition, as part of our global clinical development strategy, we now anticipate submitting regulatory filings in multiple countries for DYNE-101 in DM1 in the second quarter, with the goal of initiating patient dosing in clinical trials for both DYNE-251 and DYNE-101 in mid-2022. We believe we have the team, platform and pipeline in place to execute on our mission of delivering life-transforming therapies for people living with serious muscle diseases.”
