简要总结
This phase II trial studies how well ibrutinib with or without bortezomib and dexamethasone works in treating patients with immunoglobulin light chain amyloidosis that has come back after a period of improvement or that does not respond to treatment. Ibrutinib and bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ibrutinib with or without bortezomib and dexamethasone may work better in treating patients with relapsed or refractory immunoglobulin light chain amyloidosis.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate the overall hematologic response rate (stringent complete response [sCR] + amyloid complete response [ACR]+ very good partial response [VGPR] + partial response [PR]) during the first 6 cycles for ibrutinib with bortezomib and dexamethasone added for lack of response in patients with amyloid light chain (AL).
SECONDARY OBJECTIVES:
I. To evaluate overall hematologic response rate (sCR+ACR+VGPR+PR) of single agent ibrutinib in patients with AL.
II. To evaluate overall hematologic response rate (sCR+ACR+VGPR+PR) to ibrutinib + bortezomib and dexamethasone (Vd) in subjects with progressive disease after initial response to single agent ibrutinib.

研究组 & 干预措施
Treatment (ibrutinib, bortezomib, dexamethasone)
Patients receive ibrutinib PO QD on days 1-28. After 3 courses, patients who achieve partial response repeat treatment every 28 days for up to 18 courses in the absence of disease progression or unacceptable toxicity. Patients who do not achieve partial response after 3 courses continue receiving ibrutinib PO QD on days 1-28. Beginning at course 4, patients who do not achieve partial response also receive bortezomib SC and dexamethasone PO on days 1, 8, and 15. Treatment repeats every 28 days for up to 18 courses in the absence of disease progression or unacceptable toxicity.

结局指标
主要结局
Overall hematologic response rate during the first 6 courses for patients treated with ibrutinib, bortezomib, and dexamethasone
时间窗: Up to 6 months
Will include a confirmed stringent complete response, amyloid complete response, very good partial response, and partial response. Confirmation will be defined as a response that is maintained on two consecutive evaluations at least 2 weeks apart. Progression will be defined as either hematologic or organ progression. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Confidence intervals for the true success proportion will be calculated according to the approach of Duffy and Santner.
次要结局
- Incidence of adverse events(Up to 3 years)
- Organ response rate(Up to 3 years)
- Overall hematologic response rate for single agent ibrutinib(Up to 6 months)
- Progression-free survival(From registration to the earliest date of documentation of disease progression (on single agent or combination therapy) or death due to any cause, assessed up to 3 years)
