1. Target and Function
Basiliximab is a chimeric monoclonal antibody that specifically targets the α chain (CD25) of the interleukin-2 receptor (IL-2R) on activated T-lymphocytes [1]. By binding to CD25, basiliximab inhibits IL-2-mediated activation and proliferation of T-cells, which play a crucial role in the immune response and allograft rejection [2].
2. Medical Uses
Basiliximab is primarily used as an induction therapy in kidney transplantation to prevent acute rejection in the early post-transplantation period [3]. It is administered in two doses, with the first dose given within 2 hours before transplantation surgery and the second dose given 4 days after transplantation [4].
3. Clinical Trial Results
Recent clinical trials have demonstrated the efficacy and safety of basiliximab in kidney transplantation. A 2022 meta-analysis of randomized controlled trials found that basiliximab significantly reduced the incidence of acute rejection compared to placebo or no induction therapy [5]. Another study published in 2023 showed that basiliximab was associated with improved long-term graft survival and patient survival compared to no induction therapy [6].
4. Safety Profile
Basiliximab has a favorable safety profile, with a low incidence of adverse events [7]. The most common side effects include gastrointestinal disorders, infections, and hematologic abnormalities [8]. Serious adverse events, such as malignancies and opportunistic infections, are rare and not significantly different from placebo or other induction agents [9].
5. Molecular Engineering and Development
Basiliximab was developed using recombinant DNA technology and is produced in mouse myeloma cells [10]. It is a chimeric antibody, consisting of human constant regions and mouse variable regions [11]. The use of chimeric antibodies reduces the risk of immunogenicity and improves the pharmacokinetic properties compared to fully murine antibodies [12].
6. Potential Drug Interactions
Basiliximab may interact with other immunosuppressive agents, such as calcineurin inhibitors and corticosteroids, potentially increasing the risk of infections and other adverse events [13]. Close monitoring of immunosuppressive drug levels and dose adjustments may be necessary when using basiliximab in combination with other immunosuppressants [14].
7. New Potential Uses
Recent studies have explored the potential use of basiliximab in other solid organ transplantations, such as liver and heart transplantation [15, 16]. Additionally, basiliximab has been investigated as a treatment option for autoimmune disorders, such as rheumatoid arthritis and inflammatory bowel disease, due to its ability to modulate T-cell activation [17, 18].
8. Other Antibodies in Clinical Development
Several other monoclonal antibodies targeting the IL-2 pathway are currently in clinical development for transplantation and autoimmune disorders. These include daclizumab, a humanized anti-CD25 antibody, and inolimomab, a murine anti-CD25 antibody [19, 20]. Additionally, novel antibodies targeting other co-stimulatory pathways, such as the CD28/B7 pathway, are being investigated as potential alternatives to basiliximab [21].
