Viela Bio Reports First Quarter 2020 Financial Results and Program Highlights

Company to host investor conference call and webcast today at 5:00 pm ET

Gaithersburg, MD—May 13, 2020—Viela Bio (Nasdaq:VIE), a clinical-stage biotechnology company pioneering treatments for autoimmune and severe inflammatory disease, today reported financial results and provided program highlights for the first quarter ended March 31, 2020.

“With the PDUFA date for our lead product candidate, inebilizumab, approaching in about one month, we are nearing another major company milestone—our first potential U.S. regulatory approval,” said Bing Yao, Ph.D., Chief Executive Officer at Viela Bio. “In anticipation, our field teams have been hard at work continuing to prepare for the potential product launch. Based on positive efficacy and safety data in the pivotal N-MOmentum trial—which studied a broad, real-world spectrum of adults with neuromyelitis optica spectrum disorder, or NMOSD—we believe inebilizumab has the potential to be a first-line monotherapy option that could change the treatment paradigm for thousands of patients affected by this rare and devastating neuroinflammatory disease.”

Continued Dr. Yao: “While it is still too early to gauge the full potential impact of the COVID-19 pandemic, at present, we have been fortunate to experience minimal effects on our business and we continue to make solid progress advancing our entire pipeline. Today, we announced positive interim results from cohorts of patients with cutaneous lupus erythematosus in our ongoing Phase 1b trial of VIB7734 and we recently initiated a Phase 2b trial of VIB4920 for the treatment of Sjögren’s syndrome.”

PROGRAM HIGHLIGHTS

Inebilizumab

• Company Advances Field Planning Activities

The U.S. Food and Drug Administration (FDA) is continuing its review of the Biologics License Application (BLA) for inebilizumab, with a Prescription Drug User Fee Act (PDUFA) action date of June 11, 2020. In preparation for the potential U.S. regulatory approval of inebilizumab, Viela has hired and trained market access and sales teams, and deployed MSLs. Should Viela secure product approval, the Company anticipates being able to initiate commercial launch activities shortly thereafter.

• Viela Preparing for Additional Clinical Trials with Inebilizumab

Viela Bio recently submitted two Investigational New Drug (IND) applications to the FDA to begin human studies of inebilizumab in myasthenia gravis and IgG4-related disease, and plans to initiate Phase 3 pivotal and Phase 2b trials, respectively, in mid-year 2020. Viela Bio initiated a Phase 2 trial in 2019 for kidney transplant desensitization. Due to the COVID-19 pandemic, the Company has voluntarily paused enrollment of new patients in the kidney transplant desensitization trial.

VIB4920

• Viela Advancing Multiple Mid-Stage Studies with VIB4920

Viela dosed the first patient at the end of 2019 in a Phase 2b trial of VIB4920 for the treatment of Sjögren’s syndrome—a chronic, systemic autoimmune disease involving inflammation and destruction of the salivary and lacrimal glands which leads to severe dryness and chronic pain. Due to the COVID-19 pandemic, the Company has voluntarily paused enrollment of new patients, while those currently enrolled continue in the trial. VIB4920 is an investigational fusion protein designed to bind to CD40L, blocking the T cells’ interaction with CD40-expressing cells. In earlier clinical studies, VIB4920 demonstrated the ability to address immune overactivation in T and B cell-driven diseases such as Sjögren’s syndrome. In response to COVID-19, the Company has voluntarily paused enrollment in its Phase 2 trial in patients with kidney transplant rejection. The Company is exploring other potential indications associated with the CD40/CD40L co-stimulatory pathway in which to pursue additional clinical studies with VIB4920.

VIB7734

• Company Reports Promising Interim Results from Phase 1b Trial

Viela today reported positive interim Phase 1b data from a study with VIB7734, its novel anti-ILT7 therapy, in patients with cutaneous lupus erythematosus (CLE). The data provide preliminary evidence that VIB7734 can safely deplete plasmacytoid dendritic cells (pDCs) in these patients. In addition, the skin biopsy results, interferon signature and the Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI) scores—an important indicator that quantifies disease activity and damage in CLE patients—indicated clinically meaningful change from baseline. The drug candidate is designed to deplete pDCs by binding to ILT7, a cell surface molecule specific to pDCs. Viela looks forward to the final data from this trial and plans to provide additional information at a future medical conference.
