What does alemtuzumab do?
Alemtuzumab is a type of targeted cancer drug called a monoclonal antibody. It is a treatment for several cancers including: chronic lymphoblastic leukaemia (CLL) a rare type of leukaemia called T-cell prolymphocytic leukaemia (T-PLL)
How is alemtuzumab made?
The alemtuzumab molecule is a genetically engineered human IgG1 kappa monoclonal antibody with a molecular weight of approximately 150 kD. The humanised antibody was made by the insertion of six complementarity-determining regions (CDRs) from an IgG2a rat monoclonal antibody into a human IgG1 immunoglobulin molecule.

Is alemtuzumab cytotoxic?
Alemtuzumab, a monoclonal anti-CD52 antibody has been shown to be highly effective in B-cell chronic lymphocytic leukemia, even in fludarabine-refractory disease. The mechanism of action is currently unknown, but may rely on complement-mediated cell lysis and antibody-dependent cellular cytotoxicity.
How much does Lemtrada cost in UK?
The cost of Lemtrada is around £56,000 per person, when you compare this to Tysabri, another infusion treatment, which costs approximately £100,000 per person per year, this is a massive saving. It also could reduce the amount of disability benefit claimants as they would potentially be able to return to work.
How long does Lemtrada stay in system?
A: After IV administration, the elimination half-life of Lemtrada is approximately 2 weeks. Anti-Lemtrada binding antibodies develop in most patients (83%, 3 months after the 2nd cycle). Neutralizing antibodies also are common, detectable in 88-94% of binding antibody-positive patients 1-3 months after the 2nd cycle.
Is Campath the same as lemtrada?
Lemtrada, also known as Campath-1H or alemtuzumab, has taken a long and winding road to the FDA’s doorstep. “Campath” stands for Cambridge Pathology, where the monoclonal antibodies’ properties were first recognized as a potential treatment for disease.
What is alemtuzumab (Altena) used for?
Alemtuzumab is a humanized monoclonal antibody that selectively binds to CD52, a protein found on the surface of normal and malignant B and T cells, that is used to reduce the numbers of circulating malignant cells of patients who have B-cell chronic lymphocytic leukemia (B-CLL).
What is alemtuzumab used for in chronic lymphocytic leukemia?
Chronic lymphocytic leukemia. Alemtuzumab is used for the treatment of B-cell chronic lymphocytic leukemia (B-CLL) in people who have been treated with alkylating agents and who have failed fludarabine therapy.
Adverse effects. Alemtuzumab has been associated with infusion-related events including hypotension, rigors, fever, shortness of breath, bronchospasm, chills, and/or rash. It can also precipitate autoimmune disease through the suppression of suppressor T cell populations and/or the emergence of autoreactive B-cells.
