Sana Biotechnology | January 30, 2023
Sana Biotechnology, Inc., a firm focused on producing and delivering engineered cells as medicines, recently announced that the FDA has approved the company's Investigational New Drug (IND) application to begin a first-in-human trial of SC291 in patients with different types of B-cell malignancies.
SC291 is an allogeneic CAR T cell therapy that targets CD19. It is developed by Sana using its hypoimmune platform. The hypoimmune platform's objective is to overcome the allogeneic cells' immunologic rejection, which, if valid for SC291, could lead to prolonged CAR T cell persistence and increased rates of durable complete responses in patients with B-cell lymphomas or leukemias.
The hypoimmune platform includes disruption of the major histocompatibility (MHC) class I and class II expression to conceal cells from the adaptive immune system, which consists of antibody and T cell responses and overexpression of CD47 to inhibit activation of the innate immune cell system, especially macrophages and natural killer (NK) cells. The company has provided evidence from numerous preclinical models demonstrating the potential of this platform to cloak cells from immune detection and the therapeutic potential of SC291 for patients with B-cell malignancies.
About Sana Biotechnology
Founded in 2018, Sana Biotechnology is a firm focused on utilizing engineered cells as medicines for patients. It is constructing differentiated capabilities across the spectrum of cell and gene therapy. The company is motivated by three goals as it seeks solutions for people with poor outcomes or diseases that are currently incurable. The first is the ability to repair and control the genes in any cell in the body. It is developing innovative delivery technologies in order to deliver any payload to any cell in a precise, predictable, and repeatable manner, paving the way for next-generation in vivo gene therapy. Next comes the ability to develop pluripotent stem cells ex vivo into immune-cloaked functional cells, to replace any missing or damaged cells in the body. Finally, it believes that it can also enable broader access to its therapies by focusing on scalable manufacturing solutions, the manufacturing costs, and aligning with key stakeholders.

Evaxion Biotech A/S | January 23, 2023
Evaxion Biotech A/S, a leading clinical-stage biotechnology firm focused on the development of AI-driven immunotherapies, recently announced that FDA has granted fast-track designation for the Company's customized cancer therapy, EVX-01, in conjunction with KEYTRUDA®.
In December 2022, Evaxion gained FDA clearance to proceed with its phase 2b clinical test, where patients with metastatic melanoma are given EVX-01 in combination with KEYTRUDA®. In addition, Evaxion obtained fast-track designation for the vaccine candidate on January 17, 2023. The fast track is developed to expedite FDA's assessment of innovative, novel medications with the potential to meet an unfulfilled medical need.
EVX-01, a peptide-based immunotherapy for cancer, is Evaxion's most advanced clinical asset. The program generates a unique medicine for each patient based on gene analysis of their malignancies and matching with their immune system. The Company's proprietary AI platform, PIONEER, helps facilitate this process.
Per Norlén, CEO at Evaxion, commented," We are extremely pleased that our cancer vaccine candidate EVX-01 has received the FDA fast track designation, as it enables a potentially faster approval of the vaccine. This is first and foremost to the benefit of the patients. And it is a great validation of our AI platform, PIONEER, and our drug development candidate."

The ongoing Phase 2b clinical trial is being done at sites in Europe, the United States, and Australia. It is conducted in partnership with Merck, which supplies its PD-1 inhibitor KEYTRUDA®. The trial was launched in Australia when the first patient was enrolled in September 2022.
About Evaxion Biotech A/S
Evaxion is a clinical-stage AI-immunology™ platform company using AI, engineering expertise and drug development knowledge to identify and develop novel immunotherapies for the treatment of various cancers, bacterial diseases and viral infections. It has utilized artificial intelligence to build a diverse pipeline of candidate immunotherapies that target two of the most critical unmet medical needs in the world, cancer and infectious diseases. Its three proprietary AI platforms include PIONEER, EDEN and RAVEN.

Biocytogen | January 05, 2023
RenNano™, a fully human heavy-chain antibody platform developed by Biocytogen Pharmaceuticals Co., Ltd., has been launched officially. RenNano™ joins RenMab™ and RenLite® as the newest member of the RenMice™ family. All three RenMice™ technologies from Biocytogen work together to speed up the search and development of entirely human monoclonal, bispecific/multispecific, and single-domain antibodies (sdAbs, or nanobodies).
Camels and sharks produce heavy-chain-only antibodies (HCAb), indicating their variable domains (VHH or sdAb) are functional without pairing with the light chain. Still, humans and mice produce antibodies that require heavy and light chain coupling to be effective. Because of their molecular weight and size, sdAbs can enter solid tumor tissues and breach the blood-brain barrier. Additionally, the sdAb's larger CDR3 region allows for detecting the otherwise concealed epitopes of GPCRs and other challenging targets.
Nanobodies offer their benefits, but it's challenging to use animals that naturally make HCAbs, like camels, in large numbers to create monoclonal antibodies due to their size, slow reproduction rate, and limited offspring supply. However, humanizing camelid antibody sequences for pharmaceutical use adds another layer of complexity and time to the drug development process.
Accordingly, Biocytogen modified the constant area of the entirely human RenMab™ model to create the RenNano™ Mouse, which is genetically modified to manufacture HCAbs. RenNano™ Mouse is one of the world's most comprehensive human antibody platforms due to the substitution of the mouse genes with the complete human heavy chain variable genes.
