Purpose
Chemotherapy for the hemodialysis (HD) patient is a challenging situation because it requires special considerations including dose modifications and timing of drug administration in relation with HD sessions. Polaltuzumab vedotin (PV), an antibody–drug conjugate in which monomethyl auristatin E (MMAE) is linked to an anti-CD79b monoclonal antibody, is an extremely promising therapeutic for treating diffuse large B cell lymphoma (DLBCL), but the pharmacokinetics are unknown in HD patients.
Methods
We carried out pharmacokinetic studies of PV when administered at 1.2 mg/kg to a DLBCL patient on HD, and compared the results with that of non-HD patients. PV was administered in conjunction with bendamustine and rituximab.
Results
Serum concentration–time curves of both antibodyconjugated and unconjugated MMAE in the presented HD patient were similar compared to that of non-HD patients. We also demonstrate that elimination of both antibody-conjugated and unconjugated MMAE through HD is limited. PV administration at 1.2 mg/kg to an HD patient was also clinically feasible, and no signs of peripheral neuropathy were observed.
Conclusions
PV therapy may be a relatively safe treatment method for DLBCL patients on HD.
