– Significant and rapid improvement in both signs and symptoms of TED after two infusions of 3 mg/kg, generally consistent with prior 10 and 20 mg/kg results –
– Among 3 mg/kg VRDN-001 treated patients, 67% were proptosis responders, 56% were overall responders, 67% achieved a Clinical Activity Score (CAS) of 0 or 1, and 20% had complete resolution of their diplopia –
– Across all 21 VRDN-001 treated patients to date, 71% were proptosis responders, 67% were overall responders, 62% achieved a CAS of 0 or 1, and 54% had complete resolution of their diplopia, with a favorable safety profile seen across all dose levels –
– 3 mg/kg data support planned once-monthly low-volume subcutaneous dosing profile for VRDN-002 and VRDN-003 –
WALTHAM, Mass., Jan. 08, 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 positive topline clinical data from the third, low dose cohort in its ongoing Phase 1/2 clinical trial of VRDN-001, an anti-insulin-like growth factor 1 receptor (IGF-1R) antibody, in patients with active thyroid eye disease (TED). The Company believes this data further validate the differentiated and potentially best-in-class clinical activity of VRDN-001. The data also support the planned dosing interval for Viridian’s VRDN-002 and VRDN-003 subcutaneous programs of up to once monthly.
“The rapid and meaningful improvements in signs and symptoms of TED observed with a low dose of VRDN-001 reinforce previously reported findings in this trial, and suggest that VRDN-001 may offer a differentiated efficacy profile,” said Roger Turbin, M.D., Professor of Ophthalmology and Visual Science within the Department of Ophthalmology of Rutgers New Jersey Medical School, and an investigator on the VRDN-001 trial. “The data also support development of VRDN-001 as a patient-friendly low volume subcutaneous injection, which could reduce the burden of care for patients suffering from TED.”
VRDN-001 – Phase 1/2 proof-of-concept trial
The proof-of-concept portion of this double-blind, placebo-controlled Phase 1/2 trial evaluated two infusions of VRDN-001 administered intravenously, three weeks apart, with efficacy measured six weeks after the first dose. VRDN-001 was evaluated at doses of 3, 10, and 20 mg/kg, with each cohort designed to include six patients randomized to drug, and two patients randomized to placebo. The Company previously announced positive results from the first two dose cohorts, which demonstrated a favorable safety profile. The third cohort evaluated a VRDN-001 dose of 3 mg/kg with 6-week data announced today. In the 3 mg/kg dose cohort, nine patients were randomized to receive VRDN-001 to enable all consented patients who were eligible following screening to participate in the trial, and two patients were randomized to receive placebo. One patient receiving placebo discontinued in the trial prior to the 6-week evaluation.
VRDN-001 – Safety data
VRDN-001 was generally safe and well-tolerated by all patients treated in the three dose cohorts. There were no reported serious adverse events (SAEs), no discontinuations, and no infusion reactions in patients treated with VRDN-001 as of December 19, 2022, the most recent cut-off date for follow-up observation. The safety and tolerability profile at the 3 mg/kg dose level was generally consistent with previously reported results.
VRDN-001 – Clinical activity data
All VRDN-001 treated patients (n=21) in the 3 mg/kg (n=9), 10 mg/kg (n=6) and 20 mg/kg (n=6) cohorts were treated for two full cycles and were evaluated for changes in proptosis, clinical activity score (CAS) and diplopia. Improvement in proptosis and CAS was generally consistent across the three cohorts. A preliminary analysis of systemic IGF-1 levels, a biomarker for target engagement, shows a similar increase was also observed across the three cohorts. The following activity was observed in the 3mg/kg cohort (n=9) and across all three dose groups (n=21) at week 6:
Clinical Activity Score (CAS)
“Data from this low dose cohort expand our overall data set to 21 drug-treated patients and build additional confidence in our ongoing Phase 3 ‘THRIVE’ trial evaluating VRDN-001 in patients with active TED.” said Barrett Katz, MD, MBA, Chief Medical Officer at Viridian. “This low dose data also increases our confidence in our planned subcutaneous program, which we are advancing as a convenient, self-administered pen.”
The Company believes that data from the 3 mg/kg dose cohort of VRDN-001 validate a low volume, subcutaneous product profile for the Company’s next-generation half-life extended anti-IGF-1R antibodies VRDN-002 and VRDN-003.
VRDN-002 is a novel anti-IGF-1R monoclonal antibody that incorporates half-life extension technology. The Company previously reported that VRDN-002 demonstrated a half-life up to 43 days in healthy volunteers, supporting administration as a low-volume, subcutaneous injection up to once-monthly.
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.
The Company’s updated pharmacokinetic (PK) modeling support feasibility of ongoing development of a self-administered pen for subcutaneous administration, and a planned dosing interval of up to once-monthly for VRDN-002 and VRDN-003.
A presentation of the VRDN-001 3 mg/kg data is available under “Events and Presentations” on the Investors section of the Viridian website at viridiantherapeutics.com.

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 was generally safe and well tolerated in the trial. The Company recently initiated its THRIVE Phase 3 trial in patients with active TED to support global marketing registration.
VRDN-001 is also being evaluated in Phase 2 trial cohorts in patients with chronic TED. Pending positive results, the Company plans to start 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.
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.
