WALTHAM, Mass., March 07, 2023 (GLOBE NEWSWIRE) — Viridian Therapeutics, Inc. (NASDAQ: VRDN), a biopharmaceutical company focused on discovering and developing potential best-in-class medicines for serious and rare diseases, today announced that multiple abstracts on VRDN-001 and VRDN-002—the Company’s investigational therapies for the treatment of thyroid eye disease (TED)—will be presented at the 49^th Annual Meeting of the North American Neuro-Ophthalmology Society (NANOS), to be held March 11 to 16, 2023, in Orlando, Florida.

An oral presentation with data from the ongoing Phase 1/2 trial of VRDN-001, a full antagonist antibody to the insulin-like growth factor 1 receptor (IGF-1R), is scheduled for the morning of Tuesday, March 14, with four posters from Viridian’s TED program to be presented that evening.

“We are pleased to present this encouraging data from our TED pipeline at this important annual gathering,” said Barrett Katz, M.D., M.B.A., Chief Medical Officer of Viridian. “Taken together, the clinical and mechanistic data we are sharing at NANOS strengthen our confidence not only in VRDN-001 as we work to enroll patients in our active THRIVE Phase 3 trial, but also in our ability to develop follow-on assets with the potential for subcutaneous self-administration to decrease treatment burdens on patients and their families living with TED.”

About Viridian’s Thyroid Eye Disease Pipeline (VRDN-001, -002, and -003)

Viridian’s lead product candidate, VRDN-001, is a differentiated monoclonal antibody targeting insulin-like growth factor-1 receptor (IGF-1R), a clinically and commercially validated target for the treatment of thyroid eye disease (TED). In preclinical studies, VRDN-001 was shown to be a full antagonist of IGF-1R, with more complete receptor blockade than other anti-IGF-1R antibodies, including the only currently approved TED therapy. Data from the initial dose cohorts of the Phase 2 portion of the ongoing trial established clinical proof-of-concept for VRDN-001 in patients with active TED. Preliminary data from the ongoing trial showed treatment with VRDN-001 led to clinically meaningful reductions in proptosis, improvement in clinical activity score (CAS), and diplopia resolution. VRDN-001 had a favorable safety profile and was well tolerated in the trial. The Company recently initiated its THRIVE Phase 3 trial in patients with active TED to support a global marketing registration.

VRDN-001 is also being evaluated in Phase 2 trial cohorts in patients with chronic TED. Pending the release of that data, the Company plans to initiate its THRIVE-2 Phase 3 trial in patients with chronic TED.

The Company is advancing VRDN-002, a distinct anti-IGF-1R antibody incorporating half-life extension technology, and VRDN-003, a half-life extended version of VRDN-001. Both VRDN-002 and VRDN-003 are designed for administration as convenient, low-volume, subcutaneous injections.

VRDN-001, -002, and -003 are investigational therapies that are not approved for any use in any country.

About TED

TED is a serious and debilitating rare autoimmune disease that causes inflammation within the orbit of the eye that can cause double vision, pain, and potential blindness. TED is a progressive disease consisting of an initial active phase, followed by a transition to a secondary chronic phase. More than 50,000 and 200,000 people are estimated to suffer from active and chronic TED, respectively, in the United States and Europe.

About Viridian Therapeutics

Viridian Therapeutics is a biopharmaceutical company focused on engineering and developing potential best-in-class medicines for patients with serious and rare diseases. Viridian’s expertise in antibody discovery and engineering enables it to develop differentiated therapeutic candidates for previously validated drug targets in commercially established disease areas.

Viridian is advancing multiple candidates in the clinic for the treatment of patients with thyroid eye disease (TED). The Company recently initiated its first global Phase 3 trial called ‘THRIVE’ to evaluate the safety and efficacy of VRDN-001 in patients with active TED. Viridian is also evaluating VRDN-001 in a Phase 2 proof-of-concept trial in patients with chronic TED. In addition to its intravenously administered VRDN-001 program, the Company is advancing two candidates for its subcutaneous strategy with the goal of providing a more conveniently administered therapy to patients with TED. Viridian is developing multiple preclinical assets in autoimmune and rare diseases.
