4 Clinical Trials for Various Conditions
This registry is a observational, multi-center study designed to collect data and analyze it retrospectively on patients with cardiac amyloidosis who have been evaluated and treated at major amyloid centers across the US and internationally between 1997 and 2025.
Immunoglobulin light chain (AL) amyloidosis is the most common form of systemic amyloidosis. AL amyloidosis has many root causes and is characterized by the overproduction of AL that are secreted by clonal bone marrow plasma cells. This is a study to determine adverse events and change in disease activity in adult participants with AL amyloidosis treated with ABBV-383. Etentamig (ABBV-383) is an investigational drug being developed for the treatment of AL amyloidosis. This study in broken into 2 parts (dose escalation and safety expansion) with 5 arms. During dose escalation (arms 1-3) participants will receive 1 of 3 doses of ABBV-383 to determine the part 2 doses. After completion of the dose escalation portion of the study, the safety expansion (part 2) portion of the study will begin. Two arms (arm 4-5) will begin and participants will receive 1 of 2 doses as determined during the dose escalation portion (part 1). Around 76 adult participants with relapsed/refractory AL amyloidosis will be enrolled at approximately 20 sites across the world. Participants will receive Etentamig (ABBV-383) as an infusion into the vein for up to approximately 2 year study duration. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and questionnaires.
This is a phase 1/2 open label study of melphalan flufenamide (melflufen) in combination with dexamethasone for participants with Al amyloidosis following at least one prior line of therapy. Melflufen will be administered on Day 1 of each 28-day cycle in combination with dexamethasone on days 1 and 2. In both phases, treatment of each individual participant will continue for up to 8 cycles or until any stopping events occur. Approximately 46 participants will be enrolled. The study was intended to be a Phase 1/2 trial but was early terminated and never moved forward to Phase 2.
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.
