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 second quarter ending June 30, 2024.

“Our team continues to execute across the board as shown by the progress we have made this quarter, and we are proud to report solid progress in our TED portfolio, with both VRDN-001 phase 3 trials, THRIVE and THRIVE-2, exceeding enrollment targets, and VRDN-003 trials, REVEAL-1 and REVEAL-2, planned to initiate this month,” said Steve Mahoney, Viridian President and Chief Executive Officer. “All timelines within our FcRn portfolio remain on track, and we anticipate submitting an IND for VRDN-006 by year-end, and reporting NHP data for VRDN-008 in the second half of the year. We look forward to delivering on these multiple key program milestones this year, beginning with our THRIVE readout next month.”

RECENT PROGRESS

Thyroid Eye Disease Portfolio

VRDN-001, an intravenously delivered anti-insulin-like growth factor-1 receptor (IGF-1R) antibody

• THRIVE-2 Completed and Exceeded Enrollment in July 2024: The THRIVE-2 global phase 3 clinical trial in patients with chronic TED completed enrollment in July 2024 with a total of 188 patients, exceeding its enrollment target of 159 patients due to patient demand. Approximately 40% of the enrolled patients were from the US.

• VRDN-001 Topline Data and BLA on Track: Both VRDN-001 global phase 3 clinical studies, THRIVE and THRIVE-2, are on track for topline data readouts in September and by year-end 2024, respectively. 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,a potential best-in-class, subcutaneous, half-life extended anti-IGF-1R antibody designed as a low-volume, infrequent, and self-administered subcutaneous injection

• REVEAL-1 and REVEAL-2 on Track to Initiate in August: REVEAL-1 and REVEAL-2 are randomized, double-masked, placebo-controlled, global phase 3 clinical trials assessing the efficacy and safety of VRDN-003 in patients with active and chronic TED, respectively. In each study, Viridian plans to administer VRDN-003 subcutaneously every 4 weeks or every 8 weeks and assess outcomes versus placebo. The trials are designed to have a primary endpoint of proptosis responder rate, based on the achievement of at least 2 mm improvement in proptosis from baseline at week 24, and additional secondary outcome measures including changes from baseline in proptosis, clinical activity score (CAS), and diplopia.

• Topline Data and BLA in 2026: Viridian anticipates topline data for both REVEAL-1 and REVEAL-2 to be available in the first half of 2026 to enable a potential BLA submission by the end of 2026. The company plans to launch VRDN-003 with a commercially available auto-injector pen, if approved.

FcRn Inhibitor Portfolio

VRDN-006, a highly selective anti-FcRn Fc fragment 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.

VRDN-008, a half-life extended FcRn inhibitor designed to prolong IgG suppression and provide a potentially best-in-class subcutaneous option for patients

• NHP Data on Track for Second Half 2024: Viridian is on track to provide VRDN-008 non-human primate data, including PK and PD data, in the second half of 2024.

• Potential Best-in-Class Profile: As a half-life extended FcRn inhibitor, VRDN-008 has the potential to enable deeper and more durable suppression than existing therapies targeting FcRn.

FINANCIAL RESULTS

• Cash Position: Cash, cash equivalents, and short-term investments were $571.4 million as of June 30, 2024, compared with $613.2 million as of March 31, 2024. The company believes that its current cash, cash equivalents, and short-term investments will be sufficient to fund its operations into the second half of 2026.

• R&D Expenses: Research and development expenses were $56.2 million during the quarter ended June 30, 2024, compared to $40.1 million during the quarter ended June 30, 2023. The increase in research and development expenses was driven by increased clinical trials costs associated with our ongoing THRIVE and THRIVE-2 clinical trials, as well as increased personnel costs to support our pipeline development.

• G&A Expenses: General and administrative expenses were $16.1 million during the quarter ended June 30, 2024, compared to $19.3 million during the quarter ended June 30, 2023. The decrease in general and administrative expenses was driven by a decrease in personnel-related costs, primarily due to decreased share-based compensation expense in the current year.

• Net Loss: The company’s net loss was $65.0 million for the second quarter ended June 30, 2024, compared with $55.1 million for the same period last year.

• Shares Outstanding: As of June 30, 2024, Viridian had approximately 83,944,478 shares of common stock outstanding on an as-converted basis, which included 63,879,675 shares of common stock and an aggregate of approximately 20,064,803 shares of common stock issuable upon the conversion of 157,435 and 143,522 shares of Series A and Series B preferred stock, respectively.
