Viridian Therapeutics Enters Autoinjector Pen Device Customization and Supply Agreement with Ypsomed AG for Subcutaneous Drug Delivery in Thyroid Eye Disease

- Supply agreement supports Viridian’s development of potential first- and best-in-class subcutaneous therapies for treatment of thyroid eye disease (TED) -

- Ypsomed brings strong track record of drug-device combination approvals engineered with its proprietary YpsoMate self-injection technology -

Viridian Therapeutics, Inc. (NASDAQ: VRDN), a biotechnology company focused on discovering and developing potential best-in-class medicines for serious and rare diseases, and Ypsomed AG (SIX: YPSN), the leading developer and manufacturer of injection and infusion systems for self-medication have signed a supply agreement for Ypsomed’s customizable YpsoMate 2.25 autoinjector pen device with a fill volume of 2.0 milliliters.

As part of the agreement, Ypsomed will customize and supply YpsoMate 2.25 patient-administered delivery devices to support Viridian’s development of investigational subcutaneous therapy candidates for the treatment of thyroid eye disease (TED).

“Developing a subcutaneous therapy is an essential part of our vision to offer the most comprehensive set of therapeutic options to the TED community. Following our lead intravenous candidate, a subcutaneous therapy would bring much needed convenience to care givers and patients while potentially expanding the TED medicines market,” said Scott Myers, President and CEO of Viridian. “Thus, it’s critical that we continue to improve our therapy by packaging it in a delivery device that is as convenient and user-friendly as possible. We engaged in a rigorous selection process and concluded that, based on its strong track record of drug-device combination approvals in multiple disease areas, Ypsomed is the ideal partner to supply such a device. We’re very much looking forward to working with them.”

“We are very pleased that, together with Viridian, we may provide people affected by TED access to an innovative drug,” said Ulrike Bauer, Chief Business Officer Delivery Systems at Ypsomed. “It shows that with our platform approach, we are able to quickly and efficiently customize autoinjectors that optimally support users in the administration of their medicine.”

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 the 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 Phase 2 portion of the ongoing trial established clinical proof-of-concept for VRDN-001 delivered intravenously (IV) in patients with active and chronic TED. VRDN-001 was generally well tolerated in the trial.

The THRIVE Phase 3 trial in patients with active TED is ongoing, and the Company is currently recruiting for its second Phase 3 trial, called THRIVE-2, in patients with chronic TED.

The Company is also advancing three candidates (VRDN-001 SC, VRDN-002, and VRDN-003) designed for administration as a convenient, low-volume, subcutaneous (SC) injection for the treatment of TED.

Viridian’s goal is to bring a best-in-class IV therapy followed by a first- and best-in-class SC therapy to the market for the treatment of the TED.

VRDN-001, -002, and -003 are investigational therapies that are not approved for any use in any country.

About TED

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. According to estimates, more than 50,000 and 200,000 people suffer from active and chronic TED, respectively, in the United States and Europe.
