The combination of lenalidomide and dexamethasone can produce hematologic responses in previously treated patients with AL amyloidosis. Because lenalidomide is primarily excreted unchanged by the kidney, adjustments to the starting dose of lenalidomide are recommended to provide appropriate drug exposure in patients with moderate or severe renal impairment and in patients on dialysis. Here, we report on a study of patients with AL amyloidosis on dialysis treated with lenalidomide at a dose of 10 mg orally three times a week. Seven patients were enrolled. All patients had received prior treatment, with 57% receiving prior high‐dose melphalan and stem cell transplantation. Two patients died before evaluation of response. The most common adverse event was infection; no thromboembolic complications were seen. One patient required dose‐modification. Hematologic responses were obtained by four of the five evaluable patients. Median overall survival was 18 months. In conclusion, adjusted dose lenalidomide was reasonably tolerated and induced sustained hematologic responses in previously treated patients with AL amyloidosis on dialysis. Am. J.
