– VRDN-002 incorporates clinically validated half-life extension technology to support development as a low volume subcutaneous injection –
– Company expects to report top line VRDN-002 Phase 1 clinical data in mid-2022 –

WALTHAM, MA, USA I January 31, 2022 I Viridian Therapeutics, Inc. (NASDAQ: VRDN), a biotechnology company advancing new treatments for patients suffering from serious diseases underserved by current therapies, today announced the United States Food and Drug Administration (FDA) clearance of its investigational new drug (IND) application of VRDN-002. The Company’s next generation IGF-1R antibody, VRDN-002, is a humanized monoclonal antibody that incorporates half-life extension technology and is designed to support administration as a convenient, low-volume, subcutaneous (SC) injection for the treatment of thyroid eye disease (TED).

The IND application clearance allows the Company to proceed with its planned first-in-human Phase 1 clinical trial of VRDN-002, which is a single ascending dose study to explore safety, tolerability, pharmacokinetics and pharmacodynamics of intravenously administered VRDN-002 in healthy volunteers. Data from this Phase 1 trial are expected to be announced in mid-2022 and will inform the feasibility of a low-volume and/or low-frequency SC dosing paradigm for TED patients.

“We are excited to advance our VRDN-002 clinical development plan. We believe the incorporation of half-life extension technology into VRDN-002 may enable a differentiated, low volume subcutaneous injection, offering TED patients improved convenience and broader settings of care,” stated Jonathan Violin, Ph.D., Viridian Therapeutics’ President and CEO. “This IND acceptance is the first of multiple regulatory, clinical, and operational milestones expected in 2022, including top-line data from our VRDN-001 Phase 1/2 proof of concept trial in the second quarter of 2022, and top-line data from our VRDN-002 Phase 1 trial in mid-2022.”
