Drug class CCR5 competitor

Leronlimab ( INN ) is a humanized monoclonal antibody being developed to treat graft-versus-host disease (GvHR) from HIV , breast cancer and COVID-19 .

Mechanism of action

Leronlimab binds to the CC motif chemokine receptor 5 (CCR5), the cells of the immune system such as T cells and macrophages expressed is. In this way it competitively prevents the binding of HIV-1 to the CD4 receptor and thus acts as an entry inhibitor . Numerous other pathophysiological processes , such as tumor invasion and metastasis , the pathogenesis of non-alcoholic steatohepatitis and the development of graft-versus-host diseases, involve the CC motif chemokine receptor 5 and can be influenced by Leronlimab.

Other Information

In Leronlimab is a humanized form of a mouse - IgG4 κ antibody which biotechnologically with the help of CHO cells is produced.

Leronlimab has fast track status in the United States for combination therapy with HAART in HIV-infected patients and for the treatment of patients with CCR5- positive metastatic triple negative breast cancer (mTNBC) . For use in COVID-19 patients, the FDA has granted Emergency Investigational New Drug (EIND) status.
