简要总结
This phase II trial studies how well isatuximab works in treating patients with primary amyloidosis that has come back or does not respond to treatment. Monoclonal antibodies, such as isatuximab, may interfere with the ability of cancer cells to grow and spread.
详细描述
PRIMARY OBJECTIVES:
I. To assess the efficacy as measured by the confirmed overall hematologic response rate (partial response or better) of isatuximab in relapsed/refractory systemic light chain (AL) amyloidosis.
SECONDARY OBJECTIVES:
I. To evaluate toxicities in the treatment of relapsed/refractory AL amyloidosis with isatuximab.
II. To evaluate time to hematologic response. III. To evaluate duration of response. IV. To evaluate progression-free survival (PFS). V. To evaluate overall survival (OS).

主要结局
Assess Efficacy by Confirmed Overall Hematologic Response
时间窗: From date of enrollment until progression or death due to any cause, whichever occurs first, assessed up to 4 years
To assess the efficacy as measured by the confirmed overall hematologic response rate (partial response, very good partial response, complete response) of isatuximab in relapsed/ refractory systemic light chain (AL) amyloidosis. Measured as rate of partial response or better. Partial response is defined as a dFLC decrease of ≥ 50%, but remaining \> 4.0 mg/dL. Very good partial response is defined as the difference between involved and uninvolved FLCs \[dFLC\] \< 4.0 mg/dL. Complete response is defined as laboratory values within the normal range free light chain (FLC) ratio (0.25 - 1.65) and negative serum and urine immunofixation.
