VRDN-008

WALTHAM, Mass.--( BUSINESS WIRE )--Viridian Therapeutics, Inc. (NASDAQ: VRDN), a biotechnology company focused on discovering and developing potential best-in-class medicines for serious and rare diseases, today reported recent business highlights and financial results for the third quarter ending September 30, 2024. “ We had another exceedingly strong quarter of execution across our TED and FcRn portfolios,” said Steve Mahoney, Viridian’s President and Chief Executive Officer. “ In TED, we reported highly-compelling and positive phase 3 data for veligrotug and eagerly anticipate the readout of THRIVE-2 in December. We also initiated both pivotal phase 3 clinical trials for VRDN-003, our next-generation subcutaneous IGF-1R inhibitor. For our FcRn inhibitor portfolio, we are thrilled today to share VRDN-008 NHP data for the first time, demonstrating a potential best-in-class pharmacokinetic and pharmacodynamic profile for this half-life extended bispecific FcRn inhibitor. Together with our Fc fragment approach with VRDN-006, we believe these programs in our FcRn portfolio will bring differentiated options for patients and each contribute to an exciting pipeline beyond TED. This quarter, we also further strengthened our cash position with a financing that allows us to accelerate our R&D pipeline and extend our cash runway into the second half of 2027.” RECENT TED PORTFOLIO PROGRESS Veligrotug is an intravenously delivered anti-insulin-like growth factor-1 receptor (IGF-1R) antibody in phase 3 development for thyroid eye disease. Achieved All Primary and Secondary Endpoints in THRIVE: In September, Viridian announced positive topline results for veligrotug in THRIVE, a global phase 3 clinical trial in patients with active TED. Veligrotug met all of its primary and secondary endpoints after five infusions with high statistical significance (p < 0.0001) and was generally well-tolerated. THRIVE-2 Topline Data Readout on Track for December 2024: THRIVE-2 is a global phase 3 clinical trial assessing the efficacy and safety of veligrotug after five infusions in patients with chronic TED. THRIVE-2 completed enrollment in July 2024 with a total of 188 patients, exceeding the enrollment target of 159 patients due to patient demand, and is on track for topline readout of the 15-week primary efficacy analysis in December. Veligrotug BLA on Track for Second Half 2025: Viridian anticipates submitting a Biologics License Application (BLA) in the second half of 2025, pending data, and expects that its data package will support a marketing authorization application in Europe. VRDN-003 is a potential best-in-class, subcutaneous, half-life extended anti-IGF-1R antibody with the same binding domain as veligrotug. REVEAL-1 and REVEAL-2 Initiated in August 2024: REVEAL-1 and REVEAL-2 are designed to evaluate VRDN-003 in patients with active and chronic TED, respectively, via a subcutaneous administration every four weeks or every eight weeks. Viridian believes the THRIVE topline results provide strong evidence to support the profile of VRDN-003 as a potential best-in-class subcutaneous anti-IGF-1R antibody in a low-volume, infrequent, self-administered, subcutaneous injection designed for patients to use at home. Topline Data and BLA in 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. The company plans to launch VRDN-003 with a commercially available low-volume autoinjector for at-home administration. FCRN PORTFOLIO UPDATE WITH NEW VRDN-008 NHP DATA 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. IND on Track for Year-End 2024: Viridian is on track to submit an IND application for VRDN-006 by year-end 2024. Viridian anticipates starting a phase 1 clinical trial for VRDN-006 in healthy volunteers in early 2025 and proof-of-concept IgG reductions from that study in the second half of 2025. 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. Positive New NHP Data Confirms Half-Life Extension: In a head-to-head study, single doses of VRDN-008 demonstrated 3x the half-life of efgartigimod and showed a deeper and more sustained IgG reduction in NHPs with peak IgG reductions that were 20% deeper than efgartigimod. IgG levels returned to baseline 35 days after VRDN-008 dosing, more than twice as long as efgartigimod, which returned to baseline 14 days after dosing. VRDN-008 spared albumin and low-density lipoprotein (LDL), consistent with efgartigimod. Given that NHP data for FcRn inhibitors have been highly translatable to humans, Viridian believes this data shows the potential for VRDN-008 to be a best-in-class, extended half-life FcRn inhibitor for patients. IND Submission Expected Year-End 2025: With these positive proof-of-concept data for VRDN-008, Viridian plans to further advance IND-enabling activities and submit an IND by year-end 2025. Viridian anticipates proof-of-concept IgG reduction data in healthy volunteers in the second half of 2026. FINANCIAL RESULTS Cash Position : Cash, cash equivalents, and short-term investments were $753.2 million as of September 30, 2024, compared with $571.4 million as of June 30, 2024. The company completed a public offering in September 2024 with net proceeds of $243.2 million and believes that its current cash, cash equivalents, and short-term investments will be sufficient to fund its operations into the second half of 2027. R&D Expenses : Research and development expenses were $69.2 million during the quarter ended September 30, 2024, compared to $30.4 million during the quarter ended September 30, 2023. The increase in research and development expenses was driven by increased clinical trials costs associated with our ongoing THRIVE and THRIVE-2 pivotal clinical trials, as well as increased personnel costs to support our pipeline development. G&A Expenses : General and administrative expenses were $14.4 million during the quarter ended September 30, 2024, compared to $20.9 million during the quarter ended September 30, 2023. The decrease in general and administrative expenses was driven by a decrease in personnel-related costs, including share-based compensation expenses. Net Loss : The company’s net loss was $76.7 million for the third quarter ended September 30, 2024, compared with $47.7 million for the same period last year. Shares Outstanding: As of September 30, 2024, Viridian had 97,850,645 shares of common stock outstanding on an as-converted basis, which included 79,181,445 shares of common stock and an aggregate 18,669,200 shares of common stock issuable upon the conversion of 134,864 and 145,160 shares of Series A and Series B preferred stock, respectively.
