Luveltamab Biosimilar – Anti-FOLR1 mAb – Research Grade

Description of Luveltamab Biosimilar - Anti-FOLR1 mAb - Research Grade

The Structure of Luveltamab Biosimilar

Luveltamab Biosimilar, also known as Anti-FOLR1 mAb, is a monoclonal antibody that specifically targets the folate receptor 1 (FOLR1). It is a biosimilar version of the original Luveltamab, which was developed by the pharmaceutical company Immunomedics. Luveltamab Biosimilar is a humanized IgG1 antibody, meaning that it is composed of both human and mouse components, making it less likely to elicit an immune response in patients.

The antibody has a molecular weight of approximately 150 kDa and consists of two heavy chains and two light chains. The heavy chains are composed of four constant domains (CH1, CH2, CH3, and CH4) and one variable domain (VH), while the light chains consist of two constant domains (CL) and one variable domain (VL). The variable domains are responsible for binding to the FOLR1 receptor, while the constant domains provide stability and effector functions.

The Activity of Luveltamab Biosimilar

Luveltamab Biosimilar works by binding to the FOLR1 receptor, which is overexpressed in many types of cancer cells. This receptor is essential for the uptake of folate, a vitamin that is crucial for cell growth and division. By targeting FOLR1, Luveltamab Biosimilar inhibits the uptake of folate, leading to decreased cell growth and proliferation.

In addition to blocking folate uptake, Luveltamab Biosimilar also has other mechanisms of action. It can induce antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC), which are mechanisms by which the immune system can kill cancer cells. Luveltamab Biosimilar has also been shown to inhibit tumor angiogenesis, the process by which tumors develop their own blood supply.

The Application of Luveltamab Biosimilar

Luveltamab Biosimilar is currently being studied for its potential use in the treatment of various types of cancer, including ovarian, lung, and breast cancer. It is also being investigated as a treatment for inflammatory diseases such as rheumatoid arthritis and psoriasis.

In clinical trials, Luveltamab Biosimilar has shown promising results. In a phase II study for ovarian cancer, Luveltamab Biosimilar was well-tolerated and showed a response rate of 31% in patients with FOLR1-positive tumors. In another phase II study for lung cancer, Luveltamab Biosimilar demonstrated a response rate of 38% in patients with FOLR1-positive tumors.

As a research grade antibody, Luveltamab Biosimilar is also widely used in laboratory settings for studying the role of FOLR1 in cancer and other diseases. It can be used in various techniques such as flow cytometry, immunohistochemistry, and Western blotting to detect and quantify FOLR1 expression.

The Future of Luveltamab Biosimilar

With its multiple mechanisms of action and promising results in clinical trials, Luveltamab Biosimilar has the potential to become a valuable treatment option for various types of cancer and inflammatory diseases. As a biosimilar, it also offers a more cost-effective option for patients in need of this targeted therapy.

In the future, Luveltamab Biosimilar may also be studied for its potential use in combination with other cancer treatments, such as chemotherapy and immunotherapy. This could potentially enhance its effectiveness and lead to better outcomes for patients.

In conclusion, Luveltamab Biosimilar, also known as Anti-FOLR1 mAb, is a promising monoclonal antibody with a specific target and multiple mechanisms of action. Its structure, activity, and applications make it a valuable tool for both research and potential therapeutic use in cancer and inflammatory diseases.
