Filter by:This study seeks to enroll patients with AL amyloidosis, for whom treatment with one of the standard melphalan chemotherapy-based regimens is either not recommended or is not their preference. Pomalidomide (CC-4047) is a drug given by mouth, which can change or regulate the functioning of the immune system. So, in theory, it may reduce or prevent the production of the amyloid protein. Pomalidomide is not currently FDA-approved for AL Amyloidosis. Pomalidomide is chemically similar to thalidomide and lenalidomide, both of these drugs have been approved by the FDA for treatment of patients with multiple myeloma (MM), a disease similar to AL Amyloidosis. Participants in this study will receive pomalidomide and dexamethasone. Phase I is a dose-escalation study and dose escalation will proceed through 3 dose-levels according to standard rules in which dose levels are started sequentially after complete evaluation of the occurrence of dose-limiting toxicities. In the Phase II portion, participants will receive pomalidomide and dexamethasone using the defined maximum tolerated dose.
The purpose of this study is to determine the safety, tolerability, pharmacokinetics and pharmacodynamics of a single dose of ALN-TTR02 in healthy volunteer subjects.
High-dose melphalan (MEL) with autologous stem cell transplant (SCT) is an effective therapy for systemic AL amyloidosis (AL), but treatment-related mortality (TRM) has historically been high. The investigators performed a phase II trial of risk-adapted SCT followed by adjuvant dexamethasone (dex) and thalidomide (thal) in an attempt to reduce TRM and improve response rates. Patients with newly diagnosed AL involving £2 organ systems were assigned to MEL 100, 140, or 200 mg/m2 with SCT, based on age, renal function and cardiac involvement. Patients with persistent clonal plasma cell disease 3 months post-SCT received 9 months of adjuvant thal/dex (or dex if there was a history of deep vein thrombosis or neuropathy). TRM was 4.4%. Thirty-one patients began adjuvant therapy, with 16 (52%) completing 9 months of treatment and 13 (42%) achieving an improvement in hematological response. By intention-to-treat, overall hematological response rate was 71% (36% complete response) with 44% having organ responses. With a median follow-up of 31 months, 2-year survival was 84% (95% confidence interval: 73%, 94%). Risk-adapted SCT with adjuvant thal/ dex is feasible and results in low TRM and high hematological and organ response rates in AL patients.
The aim of the study is to evaluate the safety and efficacy of Pomalidomide and Dexamethasone in patients who did not achieve a complete response after initial treatment with both an alkylating agent (Melphalan or Cyclophosphamide) and Bortezomib. Patients who received 1 previous treatment without achieving a complete response (CR), but who could not be treated with alkylators and/or Bortezomib due to contraindications, will be included.
An ongoing trial of diflunisal has been closed for enrollment, thus, patients suitable for the study can no longer participate or receive treatment by diflunisal; and patients, who have participated in the trial can not continue their treatment. The investigators want to continue to monitor the effect of the drug on transthyretin (TTR) amyloidosis in an open label observational study. Primary endpoint will be a composite score of the manifestations of the disease (Kumamoto scale) and secondary end points will be measurements of neurological impairment, heart involvement and nutritional status.
The purpose of the study is to determine the capability of a radiolabeled amyloid-reactive monoclonal antibody to document the presence and distribution of amyloid deposits by PET/CT imaging in patients with AL amyloidosis.
This study aims to provide safety information on the ligand, GSK2315698A. The pharmacokinetics and pharmacodynamics of the ligand will be determined together with the differences in routes of dose administration, namely the tolerability between intravenous versus subcutaneous dose administration. The study will be carried out in patients with systemic amyloidosis and the ability of GSK2315698A in depleting levels of serum amyloid protein (SAP) will be measured.
The goal of this clinical trial is to determine the toxicity and also the efficacy of a treatment that includes the following treatment: Two medications, bortezomib and dexamethasone (or BD), followed by autologous stem cell transplantation, and a prolonged course of treatment with bortezomib and dexamethasone after transplantation. This type of treatment has been very effective in multiple myeloma. However, there is little experience with this treatment in patients who have Monoclonal Immunoglobulin Deposition Disease (MIDD) or amyloidosis. The investigators and others have treated patients who have MIDD and amyloidosis with bortezomib and autologous stem cell transplantation and have had success with this treatment. But the combination of autologous transplant with BD given before and after the transplant is a new way of treating these diseases, which the investigators believe will be very effective.
The purpose of this study is to provide safety information and to define the optimal induction and short term maintenance regimen for GSK2315698 to deplete circulating SAP in healthy volunteers prior to assessing in patients
This study will include participants with previously treated systemic relapsed or refractory light-chain (AL) amyloidosis who require further therapy and will be aimed at determining the safety profile and the maximum tolerated dose/recommended phase 2 dose of MLN9078 (Ixazomib) administered orally.
