Business Overview

Viridian's strategy is to identify market opportunities where there is a clear unmet need and the potential to develop differentiated products. The company then aims to engineer the best possible therapeutics and rapidly advance its programs to patients.

Thyroid Eye Disease (TED) Portfolio

Viridian's lead programs are focused on the treatment of TED, a serious and debilitating autoimmune condition characterized by inflammation and damage to the tissues around and behind the eyes. The company is developing two anti-IGF-1R antibodies for TED: VRDN-001, an intravenously (IV) delivered monoclonal antibody, and VRDN-003, a subcutaneously (SC) administered antibody.

VRDN-001 Program

VRDN-001 is Viridian's lead product candidate for the treatment of TED. In Phase 2 clinical trials, VRDN-001 demonstrated robust clinical activity and a favorable safety profile in both active and chronic TED patients after just two infusions. Viridian is currently conducting two global Phase 3 trials, THRIVE and THRIVE-2, to evaluate the efficacy and safety of VRDN-001 in patients with active and chronic TED, respectively. The company recently announced that THRIVE completed enrollment in March 2024, exceeding the target of 90 patients with a total of 113 patients enrolled, due to strong patient demand. Topline data from THRIVE is expected in September 2024, while THRIVE-2 is on track for topline readout by the end of 2024. Viridian plans to file a Biologics License Application (BLA) for VRDN-001 in the second half of 2025.

VRDN-003 Program

Viridian is also developing VRDN-003, a subcutaneous version of VRDN-001 with an extended half-life, as a potential best-in-class therapy for TED. In a Phase 1 study, VRDN-003 demonstrated a prolonged half-life of 40 to 50 days, which is four to five times longer than that of VRDN-001. This extended half-life could enable less frequent dosing, potentially improving convenience for patients. Viridian recently completed a positive Type C meeting with the FDA and is on track to initiate its pivotal program for VRDN-003 in mid-2024.

FcRn Inhibitor Portfolio

In addition to its TED programs, Viridian is developing a portfolio of engineered anti-FcRn inhibitors, including VRDN-006 and VRDN-008, to address the unmet needs of patients living with autoantibody-mediated autoimmune diseases. FcRn inhibitors represent a significant commercial opportunity, as the first FcRn inhibitor, Vyvgart, has already achieved over $1 billion in annual sales. Viridian plans to file an Investigational New Drug (IND) application for VRDN-006 by the end of 2024 and expects to share data on VRDN-008 in non-human primates in the second half of 2024.

Financials

As of March 31, 2024, Viridian had $613.2 million in cash, cash equivalents, and short-term investments, which the company believes will be sufficient to fund its operations, including its clinical development plan, into the second half of 2026. The company's strong cash position reflects its successful capital raising efforts, including a $150 million public offering in January 2024 and a $186 million private placement in November 2023.

Risks and Challenges

Viridian faces several risks and challenges common to the biopharmaceutical industry, including the inherent uncertainty of clinical development, regulatory approval processes, and commercialization. The company's success will depend on its ability to successfully navigate these challenges and advance its product candidates through clinical trials and regulatory review. Additionally, Viridian operates in a highly competitive environment, with several companies developing therapies for TED and autoimmune disorders.

Outlook

Viridian is well-positioned to continue its momentum in 2024 and beyond. The company expects to report topline data from the THRIVE trial of VRDN-001 in September 2024 and topline data from the THRIVE-2 trial by the end of 2024. Viridian also plans to initiate its pivotal program for VRDN-003 in mid-2024 and file an IND for VRDN-006 by the end of 2024. These upcoming milestones, if successful, could significantly advance Viridian's pipeline and position the company as a leader in the treatment of TED and autoimmune disorders.

Conclusion

Viridian Therapeutics is a promising biopharmaceutical company with a robust pipeline of innovative therapies targeting serious and rare diseases. The company's focus on TED and autoimmune disorders, coupled with its strong financial position and upcoming catalysts, make it an intriguing investment opportunity for those seeking exposure to the rapidly evolving rare disease and autoimmune treatment landscapes.
