WALTHAM, Mass.--(BUSINESS WIRE)-- Viridian Therapeutics, Inc. (NASDAQ: VRDN), a biotechnology company focused on discovering, developing and commercializing potential best-in-class medicines for serious and rare diseases, today reported recent business highlights and financial results for the fourth quarter and full year ended December 31, 2024.
“We made tremendous progress in 2024 which was capped off by the positive and better-than-expected pivotal data for our lead TED program veligrotug in active and chronic TED, and advancing towards the clinic with an IND submission for our lead FcRn inhibitor program VRDN-006,” said Steve Mahoney, Viridian’s President and CEO. “The veligrotug BLA submission is on track for 2H 2025 and our early commercial preparations are underway. In the new start TED market, we are excited about the potential for veligrotug to become the treatment-of-choice for patients. Our team executed throughout 2024, enrolling over 400 TED patients in veligrotug clinical trials, and we are carrying that momentum into our REVEAL studies, the phase 3 clinical trials for our potential best-in-class subcutaneous VRDN-003. Both REVEAL studies are on track to report topline data in the first half of 2026, which would enable a BLA submission by the end of 2026.”
“Turning to our FcRn inhibitor portfolio, we anticipate proof-of-concept data in healthy volunteers, including IgG reduction, in Q3 2025. We also continue to advance our bispecific, half-life extended, potential best-in-class VRDN-008 program and anticipate sharing additional data from the ongoing VRDN-008 preclinical studies later this year. Building on the execution success of 2024, we are excited to continue delivering important catalysts across both our TED and FcRn portfolios.”
TED Portfolio Progress
Veligrotug is an intravenously (IV) delivered anti-insulin-like growth factor-1 receptor (IGF-1R) antibody in phase 3 development for thyroid eye disease, with the potential to be the IV treatment-of-choice for active and chronic TED.
Positive Topline Data in THRIVE and THRIVE-2:Veligrotug achieved all primary and secondary endpoints in THRIVE and THRIVE-2, pivotal phase 3 clinical trials for patients with active and chronic TED, respectively. Pivotal Data Show a Differentiated Clinical Profile:Veligrotug showed a differentiated clinical profile in THRIVE and THRIVE-2, with a rapid onset of treatment effect and statistically significant and meaningful reduction and resolution of diplopia, including the first demonstration of diplopia response and resolution in a global chronic TED phase 3 study. Veligrotug was also generally well tolerated and had a low rate of hearing impairment, a key AE of interest, in both clinical trials. BLA On Track for 2H 2025, Marketing Authorization Application (MAA) Submission Expected 1H 2026:BLA submission is on track for the second half of 2025, with an MAA submission to the European Medicines Agency expected in the first half of 2026.
VRDN-003 is a potential best-in-class, subcutaneous, half-life extended anti-IGF-1R antibody with the same binding domain as veligrotug. Viridian designed VRDN-003 to be an infrequent, at-home, and self-administered subcutaneous injection using a low-volume autoinjector.
REVEAL-1 and REVEAL-2 Progressing as Planned:Patient enrollment and dosing continues in both phase 3 clinical trials. Topline Data On Track for 1H 2026: Viridian anticipates topline data from both REVEAL-1 and REVEAL-2 in the first half of 2026, with a BLA submission planned by year-end 2026. Viridian plans to launch VRDN-003 with a commercially available low-volume autoinjector for at-home administration.
FcRn Inhibitor Portfolio Progress
FcRn inhibitors have the potential to treat a broad array of autoimmune diseases, representing significant potential commercial market opportunities. The two marketed indications of myasthenia gravis (MG) and chronic inflammatory demyelinating polyneuropathy (CIDP) alone are projected to have a market size close to $10 billion by 2030. An additional 17 indications are currently in clinical development with an FcRn inhibitor, with dozens more autoimmune diseases thought to be addressable by FcRn inhibitors.
VRDN-006 is a highly selective Fc fragment which inhibits FcRn and is designed to be a convenient subcutaneous and self-administered option for patients.
Proof-of-Concept Phase 1 Clinical Data On Track for Q3 2025:Viridian expects data from the phase 1 clinical trial in Q3 2025, including proof-of-concept IgG reduction data in healthy volunteers.
VRDN-008 is a half-life extended bispecific FcRn inhibitor comprising an Fc fragment and an albumin-binding domain designed to prolong IgG suppression and provide a potentially best-in-class subcutaneous option for patients.
Additional Preclinical Data Expected in 2025:Non-human primate (NHP) studies are ongoing to generate additional data for VRDN-008. Once complete, Viridian plans to use the totality of VRDN-008’s NHP data to build a robust pharmacokinetic and pharmacodynamic model to enable the prediction of potential human dosing regimens for VRDN-008.
Corporate Updates
Today, Viridian announced the appointment of Radhika Tripuraneni, M.D., to the role of Chief Medical Officer, succeeding Thomas Ciulla, M.D. Dr. Tripuraneni joined Viridian in early 2024 as a consultant and brings a strong track record of leading clinical and medical teams at late-stage and commercial organizations with experience in multiple therapeutic areas, including rare disease, hematology/oncology, and neurology. Her prior roles include serving as Prothena’s Chief Development Officer and in senior clinical and medical roles at MyoKardia Inc., Synageva BioPharma Corp., and Alexion Pharmaceuticals Inc. Viridian thanks Dr. Ciulla for his contributions to Viridian’s progress and looks forward to his support as he transitions into a consulting role with the company.

Financial Results
Cash Position:Cash, cash equivalents, and short-term investments were $717.6 million as of December 31, 2024, compared with $477.4 million as of December 31, 2023. The company believes that its current cash, cash equivalents, and short-term investments will be sufficient to fund its currently planned operations into the second half of 2027.

The increase in research and development expenses was driven by increased costs associated with our ongoing clinical trials for our TED portfolio, additional investment in advancing our FcRn inhibitor portfolio, as well as increased personnel-related costs as a result of increased headcount. G&A Expenses:General and administrative expenses were $61.1 million during the year ended December 31, 2024, compared to $95.0 million during the year ended December 31, 2023. The decrease in general and administrative expenses was driven by $31.0 million in nonrecurring severance costs in 2023. Net Loss:The company’s net loss was $269.9 million for the year ended December 31, 2024, compared with $237.7 million for the same period last year.
