A Phase 1 interventional study of DC vaccines in Multiple Myeloma or Plasmacytoma, sponsored by Shenzhen Geno-Immune Medical Institute. Not yet recruiting at 1 site in China. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-11-02.
Sponsored by Shenzhen Geno-Immune Medical Institute · Phase 1, Interventional, and Treatment
The purpose of this study is to determine the feasibility, safety, and efficacy of dendritic cell (DC) vaccines in the treatment of multiple myeloma (MM) or plasmacytoma based on immune-modified DC vaccines (DCvac). This approach is aimed to achieve prolonged maintenance of remission in multiple myeloma or plasmacytoma patients.

Multiple myeloma (MM) is a plasma cell malignancy, characterized by the aberrant occupation of bone marrow with malignant plasma cells, and the destruction of bones together with the production of abnormal immunoglobulins. The clinical symptoms and signs can be manifested through various mechanisms. At present, the therapeutic drugs for MM include glucocorticoid, cytotoxic drugs, immunosuppressants, protease inhibitors, monoclonal antibodies and cell therapies including hematopoietic stem cell transplantation (HSCT). Among them, immunotherapy has been proven to be a revolutionary treatment with great potential of producing long term cure.
In the past decades, adoptively transferred T cells modified with chimeric antigen receptors (CARs) have demonstrated high effectiveness, and the CAR-T therapy has changed the treatment paradigm for many hematological malignancies. Currently, several antibody-based therapies and a few BCMA-based CAR-T cell therapies have been approved for MM treatment. However, in many MM patients, the disease may still relapse after extensive immunotherapies including auto- and allo-HSCT. We have previously reported a DC-based immune activation strategy against MM in a preclinical study. This study proposes to apply the individual patients' MM tumor antigen-based DCs as vaccines (DCvac) to booster anti-myeloma immunity, in order to prevent disease relapse. The MM patients who have achieved very good partial or complete remission will be treated with multiple DCvacs to achieve a prolonged remission without disease recurrence.
This trial protocol will inject DCvacs to MM or plasmacytoma patients who have been treated with a combination of anti-cancer regimens, including CAR-T cell therapy, and who have achieved partial or complete disease remission. The DCvacs are patient's own DCs which are immune modified to present target antigens and to activate anti-cancer immunity. The aim of this study is to evaluate the feasibility, safety, and efficacy of the innovative MM patient-based DC vaccines.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Start is estimated for Jun 2027; primary completion for Dec 2028, 18 months later.
Of 201 non-industry phase 1 interventional studies under Multiple Myeloma, half reached primary completion within 57 months of starting (the median), counting those still running; a quarter within 39 and three quarters within 99. This study's planned 18 months is below that.
Counting every sponsor, half of 413 studies reached it within 50 months; a quarter within 33 and three quarters within 75.
How these figures are worked out, and which studies are left out of them.
