WALTHAM, Mass., March 04, 2021 (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 2020 and recent business highlights.

“2020 was a transformational year for Dyne. We delivered validating data for our FORCE™ platform and programs, further strengthened our exceptional team with the addition of highly experienced leaders and completed our IPO. Together with earlier financings in 2020 and the follow-on public offering completed in January 2021, we have raised more than $550 million, which we expect to support us into the second half of 2024. We begin 2021 focused on driving our DM1, DMD and FSHD programs to the clinic as we pursue our goal of delivering potentially life-transforming therapies to people living with serious muscle diseases,” said Joshua Brumm, president and chief executive officer of Dyne.

Recent Highlights

• In January 2021, Dyne announced new preclinical data from its myotonic dystrophy type 1 (DM1) program demonstrating robust RNA knockdown of toxic human nuclear DMPK, the genetic basis of the disease. To assess the ability of its lead DM1 candidate to reduce toxic human nuclear DMPK RNA, Dyne developed an innovative hTfR1/DMSXL mouse model that expresses the human TfR1 (hTfR1) and carries a human DMPK gene that represents a severe DM1 phenotype with more than 1,000 CTG repeats. In this model, two doses (2 x 10 mg/kg) of Dyne’s candidate resulted in significant toxic human nuclear DMPK knockdown at 14 days: 60 percent in the heart; 56 percent in the diaphragm; 54 percent in the tibialis anterior and 39 percent in the gastrocnemius. In the study, Dyne’s candidate was well tolerated. Dyne expects to share data from the hTfR1/DMSXL model at a scientific meeting during 2021.
• The Company further strengthened its leadership team with the appointment of Wildon Farwell, M.D., MPH, as chief medical officer, announced separately today, and Ashish Dugar, Ph.D., MBA, as senior vice president, global head of medical affairs, in February 2021.

• In January 2021, Dyne completed its follow-on public offering of 6,000,000 shares of its common stock at a public offering price of $28.00 per share. Gross proceeds of the offering before deducting the underwriting discount and commissions and offering expenses were approximately $168 million. Dyne expects its cash, cash equivalents and marketable securities as of December 31, 2020, together with the net proceeds from the January 2021 public offering, will be sufficient to fund its operating expenses and capital expenditure requirements into the second half of 2024.

Upcoming Scientific & Investor Conference Presentations

• Dyne is scheduled to participate in the 2021 MDA Virtual Clinical & Scientific Conference. Romesh Subramanian, Ph.D., chief scientific officer, will present as part of the panel “Therapeutic Considerations for Dominant Neuromuscular Diseases,” and Oxana Beskrovnaya, Ph.D., senior vice president, head of research, will participate in the “Non-viral Delivery in Neuromuscular Disease” session. Both presentations will take place on March 15, 2021 and will be available to registered attendees at: https://mdavirtualconference.org/.
• Dr. Beskrovnaya also intends to present on Dyne’s FORCE platform during the virtual 7th Cold Spring Harbor Laboratory meeting on Nucleic Acid Therapies on March 24, 2021, which is accessible to registered participants at: https://meetings.cshl.edu/meetings.aspx?meet=NAT&year=21.
• Mr. Brumm and Dr. Subramanian are scheduled to participate in a virtual fireside chat during Stifel’s 3rd Annual CNS Day on April 1, 2021 at 10:30 am ET.
