背景信息

OMG recombinant protein, developed by Beijing Biotech OMG, is a cutting-edge therapeutic agent designed to target inflammatory and autoimmune disorders. Originating from extensive research on immune regulation pathways, this engineered protein combines human-derived sequences with proprietary modifications to enhance stability and bioactivity.

The molecule primarily functions as a cytokine inhibitor, specifically targeting key pro-inflammatory signals like IL-17 and TNF-α, which are implicated in conditions such as psoriasis, rheumatoid arthritis, and inflammatory bowel disease. Its design leverages Fc fusion technology to prolong serum half-life, requiring less frequent dosing compared to conventional biologics.

Preclinical studies demonstrate 68% higher binding affinity to inflammatory markers than existing therapies, coupled with reduced immunogenicity risks due to humanized domains. Phase II trials in China showed 82% of psoriasis patients achieving PASI-75 improvement within 12 weeks. Current applications extend beyond therapeutics, including diagnostic kits for cytokine storm monitoring and research tools for T-cell activation studies.

Production utilizes a glycoengineered CHO cell system, ensuring consistent post-translational modifications critical for function. The platform achieves >95% purity via multimodal chromatography, complying with FDA and EMA standards. As a cost-effective alternative to monoclonal antibodies, OMG recombinant protein represents China's growing innovation in next-generation biopharmaceuticals, with ongoing investigations in neuroinflammation and tumor microenvironment modulation.
