New Drug Information: Lucatumumab Anti-CD40 Monoclonal Antibody

Also known as: HCD122

Drug Information: Lucatumumab is one of several experimental anti-CD40 monoclonal antibodies. CD40 is a cellular surface protein involved in immune system signaling, which is present on cancerous B cells. The drug's developer, Novartis, believes that it both blocks proliferation of malignant cells and attracts other immune system cells to attack the cancer. It is given intravenously on a weekly basis for multi-week treatment cycles.

Lucatumumab is a fully human antibody, meaning it may cause less adverse reactions than mouse-based and chimeric antibodies already in use.

Side Effects: No information yet.

Clinical Trials: A Phase I/II trial for follicular lymphoma patients was initiated by Novartis in 2010 and is listed on It involves lucatumumab given in combination with bendamustine.

A Phase I/II clinical trial in 79 lymphoma patients, including follicular lymphoma patients, reported a 40% response rate in patients who failed to respond to rituximab. In 49 patients given the maximum tolerable dose, 4 of 12 (33%) of follicular lymphoma patients responded to lucatumumab monotherapy, including one who achieved complete remission.

  1. Hello,

    You have provided a very good site to knowing about Monoclonal antibody. These antigen used to generate the antibody is covalently attached to an agarose support, which is produce a single type of antibody that binds to a corresponding antigen. Thanks a lot for creating this type of valuable site....

  2. I find many useful things herewith. It is really amazing for us. Where ever we are, just click on the website and Take advantage .Your article impressed me very heartily. From a last decade I was searching such type of website. Thanks for giving me a space in your blog. I refer this to my close friends who are already seeking for the same .Thanks again guys…
