Biosion, Inc. and Celldex present positive preclinical data at SITC 2021. CDX-585 is the first compound from Celldex’s research and collaboration agreement with Biosion, Inc. and combines Celldex’s ILT4 mAb with Biosion’s PD-1 mAb.

Celldex Presents Positive Preclinical Data from PD-1/ILT4 Bispecific Antibody Program CDX-585 at SITC 2021

HAMPTON, N.J., November 12, 2021 — Celldex Therapeutics, Inc. today announced positive preclinical data from CDX-585, the Company’s bispecific antibody with dual targeting of ILT4 and PD-1 checkpoint pathways, developed from its bispecific antibody platform. These data were presented in a poster session as part of the Society for Immunotherapy of Cancer’s 36th Annual Meeting (SITC 2021).

The data show CDX-585 effectively combines the blockade of ILT4 and PD-1 into one molecule, with favorable biophysical and functional characteristics, supporting the initiation of development activities including manufacturing and IND-enabling studies. CDX-585 is the first compound from Celldex’s research and collaboration agreement with Biosion, Inc. and combines Celldex’s ILT4 mAb with Biosion’s PD-1 mAb.

“We are pleased with this data which demonstrate we have successfully combined two important pathways into one molecule and support the further advancement of CDX-585,” said Tibor Keler, Ph.D., Executive Vice President and Chief Scientific Officer of Celldex Therapeutics. “We believe that co-targeting ILT4 and PD-1, which are both critical checkpoint pathways, has the potential to produce significant immune enhancing and antitumor effects. We are excited to move forward with CDX-585 in addition to the continued generation of other candidates from our bispecific antibody platform for oncology and inflammatory diseases.”

In the preclinical data presented at SITC, the simultaneous inhibition of ILT4 and PD-1 checkpoints with CDX-585 led to myeloid and T cell activation which may potentially demonstrate clinical utility, particularly in the T cell checkpoint inhibitor refractory setting. CDX-585 promoted T cell activation as measured by mixed lymphocyte reactions superior to that achieved by the combination of ILT4 and PD-1 monoclonal antibodies. CDX-585 also demonstrated anti-tumor activity in a humanized mouse model of melanoma and had a favorable pharmacokinetic profile in pilot studies, without adverse effects of treatment noted in clinical observations or clinical chemistry.

The poster presented at SITC can be viewed on the “Publications” page of the “Science” section of the Celldex website.

About CDX-585

CDX-585 is a dual targeting PD-1/ILT4 bispecific antibody from Celldex’s bispecific antibody platform, currently in preclinical studies including manufacturing and IND-enabling studies. Expression of ILT4 in several tumor types is associated with poor outcome and in preclinical models, antagonist antibodies to ILT4 have demonstrated immune enhancing and antitumor effects. CDX-585 is being developed as part of a research and collaboration agreement with Biosion, Inc.

About Celldex’s Bispecific Antibody Platform

Celldex’s deep antibody experience and in-house manufacturing capabilities support efficient development of next generation bispecific antibody programs for inflammatory/autoimmune diseases and oncology. Bispecific antibodies can engage two independent pathways involved in controlling immune reactions and combining these into one molecule can result in stronger activity than a combination of the independent antibodies. Targets are being selected based on new science as well as their compatibility to be used in bispecific antibody formats with Celldex’s existing antibody programs. Lead targets in development are emerging as important pathways controlling inflammatory diseases or immunity to tumors.

About Celldex Therapeutics, Inc.

Celldex is a clinical stage biotechnology company dedicated to developing monoclonal and bispecific antibodies that address devastating diseases for which available treatments are inadequate. Our pipeline includes antibody-based therapeutics which have the ability to engage the human immune system and/or directly affect critical pathways to improve the lives of patients with inflammatory diseases and many forms of cancer.

Biosynergics, Inc. Completes Series A Financing and Company Restructuring

On October 29, 2017, Biosynergics, Inc. (“Biosynergics”), a China-based startup biotech company, announced that it has completed a 30 million RMB Series A financing. The Series A round was exclusively invested in by Shenzhen Renhe Capital. After completion of the financing, Shenzhen Renhe Capital (“SRC”) and Biosynergics co-registered a new entity named as Biosion, Inc. (“Biosion”) in Nanjing, China. Going forward, Biosynergics will operate as a wholly-owned subsidiary of Biosion.

The rationale for restructuring of Biosynergics was driven by three considerations. First, Biosyngerics has developed and directed its core antibody drug discovery business to minimize preclinical drug development risks while accelerating the clinical and commercial antibody drug pipeline success of its current and future biopharmaceutical clients. Second, Biosynergics has successfully recruited highly trained scientific talent to continue its execution on its business plan and will continue putting the effort of attracting more top talents in the near future. Third, the critical investment and restructuring required to create Biosion, now enables a strategic path forward to enhance and expand its capabilities as necessary through a future IPO. The newly established company, Biosion will focus on innovative antibody drug discovery and early preclinical drug development while Biosynergics will continue its existing business scope of In VitroDiagnosis(IVD) critical raw materials supply and CRO services.

Dr. Mingjiu Chen, Founder and CEO of Biosion stated “We are very pleased that our recent achievements and future growth potential were recognized by the Renhe Capital team. Exploiting our proprietary H³ (High-throughput High-content High-efficiency) antibody platform and SynAb™ (Synergistic Antibody) technology, we are able to interrogate very large, program-specific, antibody collections that result in the discovery and development of both First-in-Class and Best-in-Class antibody drug candidates. With SRC’s investment and their capital management experience, we anticipate that our antibody drug discovery pipeline will be accelerated and our corporate operation efficiency will be further optimized.”

“The demonstrated excellent performance of the Biosynergics team to date and the great growth potential of China’s biotechnology industry are the main considerations for today’s investment,” commented Mr. Weichun Ji, CEO of Shenzhen Renhe Capital. “Furthermore, leveraging their core business of innovative antibody drug discovery and early development, Biosion offers a very unique value proposition to its biopharmaceutical partners to increase the speed and success rate of their antibody drug development. Biosion team has demonstrated a combination of great technical expertise, a thoughtful and clear understanding of marketing strategy, and a strong implementation capability. During our due diligence, we have received very positive feedbacks from both Biosion’s current clients and from the experts from the industry. We are truly pleased to work with Biosion team to promote the innovation of China’s antibody drug industry.”
