Mirzotamab Biosimilar – Anti-CD276, B7-H3 mAb – Research Grade

Description of Mirzotamab Biosimilar - Anti-CD276, B7-H3 mAb - Research Grade

Title: Mirzotamab Biosimilar – A Promising Antibody for Targeting CD276, B7-H3

Introduction:

Mirzotamab Biosimilar is a novel antibody that specifically targets CD276, also known as B7-H3, a promising therapeutic target in cancer research. This biosimilar is a research grade version of mirzotamab, a humanized monoclonal antibody that has shown promising results in preclinical and clinical studies for the treatment of various types of cancer.

Structure of Mirzotamab Biosimilar:

Mirzotamab Biosimilar is a recombinant humanized monoclonal antibody with a molecular weight of approximately 150 kDa. It is composed of two identical heavy chains and two identical light chains, connected by disulfide bonds. The antibody has a typical Y-shaped structure, with two antigen-binding fragments (Fab) and one crystallizable fragment (Fc). The Fab region is responsible for binding to the target antigen, CD276, while the Fc region is involved in effector functions, such as antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC).

Activity of Mirzotamab Biosimilar:

Mirzotamab Biosimilar specifically targets CD276, a cell surface protein that is overexpressed in various types of cancer, including breast, lung, ovarian, and prostate cancer. CD276 is a member of the B7 family of co-stimulatory molecules, which play a crucial role in regulating immune responses. It is known to promote tumor growth and metastasis by suppressing anti-tumor immune responses and promoting angiogenesis. By binding to CD276, Mirzotamab Biosimilar blocks its interaction with its receptors on immune cells, thereby restoring anti-tumor immune responses and inhibiting tumor growth.

Application of Mirzotamab Biosimilar:

Mirzotamab Biosimilar has shown promising results in preclinical studies for the treatment of various types of cancer. In a study on breast cancer, treatment with mirzotamab significantly inhibited tumor growth and metastasis in mice. In another study on lung cancer, mirzotamab treatment led to a significant reduction in tumor growth and improved survival in mice. These results suggest that mirzotamab may be effective in treating a wide range of cancers that overexpress CD276.

In addition to its potential as a monotherapy, Mirzotamab Biosimilar also has the potential for combination therapy. It has been shown to enhance the anti-tumor activity of other cancer therapies, such as chemotherapy and immune checkpoint inhibitors. This makes it a promising candidate for use in combination with other treatments to improve their efficacy.

Conclusion:

Mirzotamab Biosimilar is a promising antibody that specifically targets CD276, a cell surface protein that is overexpressed in various types of cancer. Its unique structure and mechanism of action make it a promising candidate for the treatment of cancer. With its potential for monotherapy and combination therapy, Mirzotamab Biosimilar has the potential to significantly improve the treatment outcomes for cancer patients. Further clinical studies are needed to fully evaluate the efficacy and safety of this biosimilar, but the current evidence suggests that it may be a valuable addition to the arsenal of cancer treatments.
