Vir Biotechnology Completes Enrollment of Phase 2 Chronic Hepatitis Delta SOLSTICE Trial Ahead of Schedule - Seite 2

About Tobevibart

Tobevibart is an investigational subcutaneously administered antibody designed to block entry of hepatitis B and hepatitis delta viruses into hepatocytes and to reduce the level of virions and subviral particles in the blood. Tobevibart, which incorporates Xencor’s Xtend and other Fc technologies, has been engineered to potentially function as a T cell vaccine against hepatitis B virus and hepatitis delta virus, as well as to have an extended half-life. Tobevibart was identified using Vir’s proprietary mAb discovery platform.

About Elebsiran

Elebsiran is an investigational subcutaneously administered hepatitis B virus-targeting small interfering ribonucleic acid (siRNA) that Vir believes has the potential to stimulate an immune response and have direct antiviral activity against hepatitis B virus and hepatitis delta virus. It is the first siRNA in the clinic to include Enhanced Stabilization Chemistry Plus (ESC+) technology to enhance stability and minimize off-target activity, which potentially could result in an increased therapeutic index. Elebsiran is the first asset in the Company’s collaboration with Alnylam Pharmaceuticals, Inc. to enter clinical trials.

These forward-looking statements are based on Vir’s expectations and assumptions as of the date of this press release. Forward-looking statements contained in this press release include, but are not limited to, statements regarding Vir’s strategy and plans; the potential benefits, safety and efficacy of tobevibart and elebsiran for the treatment of chronic hepatitis delta; the timing and design of the Phase 2 SOLSTICE clinical trial, including enrollment and the anticipated timing of data readouts or presentations; statements regarding Vir’s scientific and executional expertise; and risks and uncertainties associated with drug development and commercialization. Many factors may cause differences between current expectations and actual results, including risks of unexpected safety or efficacy data or results observed during the Phase 2 SOLSTICE trial or in data readouts; the occurrence of adverse safety events; risks of unexpected costs, delays or other unexpected hurdles; the timing and outcome of Vir’s planned interactions with regulatory authorities; difficulties in obtaining regulatory approval; challenges in accessing manufacturing capacity; clinical site activation rates or clinical trial enrollment rates that are lower than expected; difficulties in collaborating with other companies; successful development and/or commercialization of alternative product candidates by Vir’s competitors; changes in expected or existing competition; delays in or disruptions to Vir’s business or clinical trials due to geopolitical changes or other external factors; and unexpected litigation or other disputes. Drug development and commercialization involve a high degree of risk, and only a small number of research and development programs result in commercialization of a product. Results in early-stage clinical trials may not be indicative of full results or results from later-stage or larger-scale clinical trials and do not ensure regulatory approval. You should not place undue reliance on these statements, or the scientific data presented. Other factors that may cause actual results to differ from those expressed or implied in the forward-looking statements in this press release are discussed in Vir’s filings with the U.S. Securities and Exchange Commission, including the section titled “Risk Factors” contained therein.
