Carfilzomib is a proteasome inhibitor licenced to treat multiple myeloma; autonomic and peripheral neuropathy are uncommon toxicities with carfilzomib. There is limited data on the use of carfilzomib in AL amyloidosis. Here, we report the results of a phase Ib dose-escalation study of Carfilzomib-Thalidomide-Dexamethasone (KTD) in relapsed/refractory AL amyloidosis. RESULTS: The trial registered 11 patients from 6 UK centres from September 2017 to January 2019; 10 patients received at least one dose of trial treatment. 80 adverse events were reported from 10 patients in the 1st three cycles. One patient experienced dose-limiting toxicity (acute kidney injury) at a dose of 45 mg/m2, and another patient had a SAR (fever). Five patients experienced an AE {$\ge$} grade 3. There were no haematologic, infectious, or cardiac AE {$\ge$} grade 3. The overall haematological response rate (ORR) at the end of three cycles of treatment was 60\%. CONCLUSION: Carfilzomib 45 mg/m2 weekly can be safely given with thalidomide and dexamethasone. The efficacy and tolerability profile appears comparable to other agents in relapsed AL amyloidosis. These data provide a framework for further studies of carfilzomib combinations in AL amyloidosis.}, url = {https://doi.org/10.1080/13506129.2023.2169124} }
