Tumor-Associated Antigen-Specific Cytotoxic T-Lymphocytes for Multiple Myeloma
(TACTAM)
What this study is about
This study is for patients that have a cancer called Multiple Myeloma, monoclonal gammopathy of undetermined significance (MGUS) or smoldering myeloma (SM). MGUS and SM have tumor cells that possess nearly identical properties to the cancer cells seen in patients with multiple myeloma.
View original scientific description
This study is for patients that have a cancer called Multiple Myeloma, monoclonal gammopathy of undetermined significance (MGUS) or smoldering myeloma (SM). MGUS and SM have tumor cells that possess nearly identical properties to the cancer cells seen in patients with multiple myeloma. The investigators would like to target proteins that are expressed by these cells using the patient's own immune cells known as T lymphocytes.This research study uses special immune system cells called tumor associated antigen (TAA)-specific cytotoxic T lymphocytes (CTLs), a new experimental therapy. The proteins that investigators are targeting in this study are called tumor associated antigens (TAAs). These are cell proteins that are specific to the cancer cell.They either do not show or show up in low quantities on normal human cells. In this study the investigators are targeting five common TAAs called NY-ESO-1, MAGEA4, PRAME, Survivin and SSX. On a different protocol, patients have been treated and so far this treatment has shown to be safe. Investigators now want to try this treatment in patients with multiple myeloma or if the investigators can arrest the progression of the patient's condition condition (described above) to multiple myeloma. These TAA-specific CTLs are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to find the largest safe dose of TAA-specific CTLs, to learn what the side effects are, and to see whether this therapy might help patients with multiple myeloma monoclonal gammopathy of undetermined significance (MGUS) or smoldering myeloma (SM) .
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
