Spots Global Cancer Trial Database for Ibrutinib With or Without Bortezomib and Dexamethasone in Treating Patients With Relapsed or Refractory Immunoglobulin Light Chain Amyloidosis

Study Description

Brief Summary: 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.

Detailed Description: 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. III. To describe the toxicities associated with ibrutinib, alone and in combination with Vd, in patients with AL. IV. To determine the organ response in AL patients treated with ibrutinib alone and in combination with Vd. V. To determine 3 year progression free survival of AL patients on the study. TERTIARY OBJECTIVES: I. To characterize health related quality of life of patients. II. To determine the caregiver and patient disease burden. III. To determine the correlation between cardiac biomarkers and hematologic response to therapy. IV. To evaluate the effect of ibrutinib on AL microenvironment. V. To characterize BTK expression in neoplastic plasma cells. VI. To evaluate the characterization of CD38 expression on neoplastic plasma cells. OUTLINE: Patients receive ibrutinib orally (PO) daily (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 subcutaneously (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. After completion of study treatment, patients are followed up every 3 months for 1 year, and then every 6 months for 2 years.
