| Description | Motavizumab (MEDI-524, NUMAX, NISTmAb) is a second generation monoclonal antibody (mAb) derived from palivizumab (Synagis) using affinity maturation techniques. Motavizumab is currently undergoing US Food and Drug Administration review as a treatment for respiratory syncytial virus (RSV) prophylaxis. It has been evaluated in large-scale clinical studies, and has demonstrated efficacy in reducing the disease burden of RSV in high-risk infant populations. Motavizumab (MEDI-524, NUMAX, NISTmAb) has higher affinity and a longer half-life, was effective in reducing RSV hospitalization in high-risk full-term infants in the US, but was not licensed due to safety concerns (allergic reactions). |

| Background | Palivizumab (brand name Synagis) is a humanized IgG monoclonal antibody (mAb) manufactured by MedImmune with recombinant DNA technology. It is used in the prevention of respiratory syncytial virus (RSV) infections. It is recommended for infants that are high-risk because of prematurity or other medical problems such as congenital heart disease. Palivizumab directed against an epitope in the A antigenic site of the F protein of RSV. Palivizumab is a composite of human (95%) and murine (5%) antibody sequences. The human heavy chain sequence was derived from the constant domains of human IgG1 and the variable framework regions of the VH genes Cor and Cess. The human light chain sequence was derived from the constant domain of Cκ and the variable framework regions of the VL gene K104 with Jκ -4. The murine sequences were derived from a murine monoclonal antibody, Mab 1129, in a process that involved the grafting of the murine complementarity determining regions into the human antibody frameworks. Palivizumab is composed of two heavy chains and two light chains and has a molecular weight of approximately 148, 000 Daltons. Palivizumab was approved for medical use in 1998 but the indications for prophylaxis vary worldwide. Palivizumab is primarily indicated for the following conditions: prematurity (gestational age ≤ 35 weeks), bronchopulmonary dysplasia/chronic lung disease, hemodynamically significant congenital heart disease, and other serious medical disorders on an ad hoc basis. Infants with these medical conditions are at increased risk of more severe disease and more serious subsequent sequelae.
