WALTHAM, Mass., March 08, 2023 (GLOBE NEWSWIRE) — Viridian Therapeutics, Inc. (NASDAQ: VRDN), a biotechnology company focused on discovering and developing potential best-in-class medicines for serious and rare diseases, today announced financial results for the fourth quarter and full year ended December 31, 2022.

“2022 was a productive year for Viridian, as we made significant progress and reached multiple important milestones in our TED program with VRDN-001, our lead product candidate. Building on this positive momentum, we are strategically positioned to continue the advancement of our pipeline of TED programs in 2023,” said Scott Myers, President and CEO of Viridian Therapeutics. “As part of my recent appointment as CEO, I look forward to advancing our recently initiated THRIVE Phase 3 trial of VRDN-001 in patients with active TED, generating data in patients with chronic TED, continuing the development of our subcutaneous programs, and beginning to establish our commercial capabilities. These activities support our overall goal to build a fully integrated biopharmaceutical company.”

Added Mr. Myers: “We also look forward to providing additional details on one of our preclinical programs later this year. Our preclinical programs have the potential to expand our current pipeline beyond TED and build on our strategy of developing best-in-class medicines that address known limitations of current therapies.”

Program highlights

Thyroid eye disease (TED)

Intravenous (IV) program: VRDN-001
Viridian’s lead product candidate, VRDN-001, is a monoclonal antibody believed to act as a full antagonist of insulin-like growth factor-1 receptor (IGF-1R). VRDN-001 is being evaluated in clinical trials for the treatment of active and chronic TED.

• In January 2023, the Company announced positive data from the third, low-dose cohort in its ongoing Phase 1/2 clinical trial of VRDN-001 in patients with active TED.
• In December 2022, the Company announced that the first patient was enrolled in its THRIVE Phase 3 trial evaluating the efficacy and safety of VRDN-001 in patients with active TED, with topline results expected in the middle of 2024.
• Clinical and non-clinical presentations of VRDN-001 are expected at the 49^th Annual Meeting of the North American Neuro-Ophthalmology Society (NANOS) from March 11^th to 16^th, 2023, in Orlando, Florida.
• Initial results from the proof-of-concept study of VRDN-001 in patients with chronic TED are expected in the second quarter of 2023.

• Initiation of the THRIVE-2 Phase 3 trial evaluating the efficacy and safety of VRDN-001 in patients with chronic TED is planned for the middle of 2023, with topline results expected by year-end 2024.

Subcutaneous (SC) programs: VRDN-001, VRDN-002, and VRDN-003
The Company is advancing VRDN-001, VRDN-002, and VRDN-003 as SC program candidates. All three candidates have the potential to be developed into a convenient, SC, self-administered pen device. VRDN-001 IV’s low-dose data support its potential as a SC candidate. VRDN-002 is a novel anti-IGF-1R monoclonal antibody incorporating half-life extension technology. VRDN-003 is an anti-IGF-1R monoclonal antibody with the same amino acid sequence as VRDN-001, except for the addition of the half-life extension technology that is incorporated in VRDN-002.

• In January 2023, the Company announced that updated pharmacokinetic (PK) modeling support feasibility of ongoing development of a self-administered pen for SC administration, and a planned dosing interval of up to once monthly for its SC program candidates.

• A clinical poster presentation of VRDN-002 Phase 1 data in healthy volunteers is expected at the 49^th Annual Meeting of NANOS from March 11^th to 16^th, 2023 in Orlando, Florida.

• The filing of the investigational new drug application (IND) for VRDN-003 with the US Food and Drug Administration (FDA) is planned for the second quarter of 2023.

• The Company plans to initiate Phase 1 trials in healthy volunteers for both VRDN-003 and VRDN-001 SC, with topline results expected in the fourth quarter of 2023.

• VRDN-002 proof-of-concept trial results in patients with active TED are expected by year-end 2023.

• The Company expects to select its lead SC program by year-end 2023 and advance the selected SC program into a pivotal trial in the middle of 2024.
