Ligand References Clinical and Disease comments
Immuno Disease Comments: Approved to prevent renal, cardiac and hepatic allograft rejection. Withdrawn from the US market.
Clinical Use: Used to prevent renal, cardiac and hepatic allograft rejection. Due to reduced demand and use in the US, the manufacturer has withdrawn muromonab-CD3 from the US market. | View clinical data
Bioactivity Comments: We have been unable to find affinity data for this antibody from any open access source. | View biological activity
Immuno Disease Comments: Approved drug for the prophylaxis of organ rejection after kidney transplant in EBV-exposed patients.
Clinical Use: Approved for prophylaxis of organ rejection after kidney transplant.
The first analysis of long-term outcomes (7 years post-transplant) for belatacept-induced immunosuppression compared to cyclosporine treatment are reported by Vincenti et al. (2016) [8]. These results, from clinical trial NCT00256750, show a clear and significant benefit from treating with belatacept rather than cyclosporine. The authors suggest that the improvement is likely due to the alternative mechanism of action of belatacept (blocks T-cell costimulation) and its non-nephrotoxic nature, in comparison to cyclosporine which is often the cause of failure of transplanted kidneys over time. | View clinical data
Bioactivity Comments: Belatacept binds to human CD86 with an IC50 of 0.102µg/mL and to CD80 with an IC50 of 0.009µg/mL [5]. | View biological activity
Immuno Disease Comments: Approved specifically as prophylaxis of renal transplant rejection.
Clinical Use: Sirolimus is used for prophylaxis of renal transplant rejection [3,7], and may be used in combination with . In June 2015 the US FDA approved sirolimus for the treatment of lymphangioleiomyomatosis, a rare proliferative but benign lung disease [6]. | View clinical data
Bioactivity Comments: In vitro studies have been performed and these show that sirolimus inhibits MERS-CoV infection of Huh7 cells [2,4]. This mechanism could also be applied to SAR-CoV-2 infection. | View biological activity
Immuno Disease Comments: Used in combination with other anti-rejection drugs (cyclosporin A, corticosteroids, azathioprine and mycophenolate mofetil) to prevent renal allograft rejection.
Clinical Use: Prophylaxis of acute organ rejection in adults following cadaveric- or living-donor renal transplantation | View clinical data
Bioactivity Comments: Peptide sequence analysis reveals that patent US6383487 [1] covers the design and uses of basiliximab. However, this patent does not provide affinity data for the interaction between the antibody and its target, IL-2, and we have been unable to find accessible data elsewhere. | View biological activity
