April 16, 2024 updated by: Zhi-Hong Liu, MD, Nanjing University School of Medicine

Daratumumab and Dexamethasone Combined With Pomalidomide (DPD) or ASCT in the Treatment of Newly Diagnosed Systemic Light Chain Amyloidosis (AL Amyloidosis): a Prospective, Single Center Clinical Trial

This is a prospective, single-center study exploratory clinical trial, aim to exploring the efficacy and safety of daratumumab in patients with AL amyloidosis, patients were divided into three groups: one group received long-term treatment with daratumumab based regimen, and the other group received autologous stem cell transplantation after two standard treatment courses with daratumumab based regimen, and the third group consists of newly diagnosed stage IIIb AL amyloidosis patients who plan to receive DPD treatment. The purpose of this study is to observe the efficacy and safety of Daratumumab, in the treatment of newly diagnosed systemic AL amyloidosis.

Detailed Description

This is a prospective, single-center study exploratory clinical trial, aim to exploring the efficacy and safety of daratumumab in patients with AL amyloidosis, patients were divided into three groups: one group received long-term treatment with daratumumab based regimen (group A) and the other group received autologous stem cell transplantation after two standard treatment courses with daratumumab based regimen (group B) , and the third group consists of newly diagnosed stage IIIb AL amyloidosis patients who plan to receive DPD treatment (group C). Participants with AL Amyloidosis will receive the drug daratumumab by IV infusion once weekly for two months, then every 2 weeks for four months, then once each month. Study treatment may continue until disease progression, unacceptable toxicity, or decision to withdraw from the trial. Disease evaluations will be performed every three months until disease progression. Group C were given Daratumumab (16mg/kg), dexamethasone (40mg) and pomalidomide. The usage of Daratumumab and dexamethasone is the same as group A and B. Patients received oral pomalidomide on days 1-21 of a 28-days cycle from cycle 1 to 6. The dose of pomalidomide is adjusted based on the patient's renal function and ECOG score.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Participants must be aged ≥18 and ≤75 years;
  2. Newly diagnosed AL amyloidosis ((confirmed by pathological examination with at least one major organ involvement (heart, kidney, or liver));
  3. In group A and B, according to the Mayo 2004 staging system, the disease is classified as stage Ⅰ-ⅢA; In group C, according to the Mayo 2004 staging system, the disease is classified as stage IIIB: NT⁃proBNP>8500ng/L and cTnT>0.035μg/L or cTnI>0.01g/L;
  4. Participants must personally sign an informed consent form approved by the Ethics Committee before the start of the study;
  5. Expected survival ≥ 12 weeks;
  6. ECOG performance status≤ 2;
  7. Female participants of childbearing potential must agree to use effective contraception from the day of signing the informed consent until 365 days after the infusion. Effective contraception is defined as abstinence or the use of a contraceptive method with a failure rate of <1% per year.
