“This placement was well-received by several leading international long-only funds and was significantly oversubscribed, reflecting strong capital market confidence in Everest’s commercial execution capabilities and innovative R&D strengths,” said Rogers Yongqing Luo, Chief Executive Officer of Everest Medicines. “It also underscores investors’ endorsement of our long-term strategic vision. We will use the proceeds to accelerate the development of innovative pipelines and our proprietary AI+mRNA platform, while advancing the commercialization of our existing portfolio. With a strengthened capital base, we are poised to drive both commercialization and innovation, delivering greater value to patients and shareholders.”

Everest has built an industry-leading, fully integrated, and localized AI+mRNA platform, enabling the development of multiple oncology and autoimmune disease programs, including EVM14, an off-the-shelf therapeutic mRNA cancer vaccine; EVM16, a personalized mRNA cancer vaccine; and an in vivo CAR-T program aimed at building a differentiated portfolio of precision immunotherapies.

• The first patient has been dosed with Everest’s internally developed personalized mRNA cancer vaccine (PCV) EVM16 at Peking University Cancer Hospital in the investigator-initiated clinical trial (IIT). Early results showed strong immunogenicity and specific T-cell responses even at a low starting dose in advanced cancer patients.

• The Investigational New Drug (IND) application for EVM14, a Tumor-Associated Antigen (TAA) vaccine, has been accepted by both the National Medical Products Administration (NMPA) of China and the U.S. Food and Drug Administration (FDA), making it Everest's first mRNA cancer therapeutic vaccine to achieve dual IND submissions in both China and the United States. The first clinical batch of EVM14 was successfully released from Everest’s Jiashan manufacturing site on June 9, and is anticipated to be delivered to U.S. clinical centers by mid-August. This batch will support the clinical trials of EVM14 in both China and the United States (US).

• Everest’s in vivo CAR-T program is founded upon its proprietary targeted LNP (tLNP) delivery system and has shown promising results in both humanized mouse models and non-human primates. It offers key advantages including off-the-shelf availability, lymphodepletion-free administration, and dose controllability.

EVER001, a next-generation covalent reversible BTK inhibitor with global rights, is advancing through global multi-center clinical studies for glomerular diseases such as primary membranous nephropathy (pMN). Positive results from its Phase 1b/2a clinical trial demonstrated rapid onset, durable response, good tolerability, and oral convenience, offering strong potential to address unmet needs in renal disease treatment worldwide.

NEFECON?, the first and only etiological treatment for IgA nephropathy (IgAN) full approved in China, the U.S., and Europe, continues to gain strong commercial traction in China following its inclusion in the National Reimbursement Drug List (NRDL), benefiting over 20,000 patients to date. Everest is also accelerating the development of its proprietary diagnostic test for Gd-IgA1 to build an integrated disease management ecosystem encompassing diagnosis, treatment, and long-term care.

The New Drug Application (NDA) for Etrasimod (VELSIPITY?) has been accepted in Mainland China, with approval anticipated between late 2025 and early 2026. The NDA has also been accepted in South Korea. VELSIPITY? has been commercially launched in Macao SAR, Singapore and Hong Kong SAR in 2024. As Everest’s third commercialized product, VELSIPITY? has been officially approved by the Guangdong Provincial Medical Products Administration for adult patients with moderately to severely active UC. It is now available at medical institutions designated under the Connect Policy in the Greater Bay Area. In March 2025, Everest has launched the construction project at its Jiashan manufacturing site to support the local production for VELSIPITY?.

Everest Medicines is accelerating the strategic advancement of its core pipeline and AI+mRNA technology platforms to further solidify its position as a leading innovative biopharmaceutical company in Asia.
