Study summary

KSVCBD injection is an in vivo Chimeric Antigen Receptor T-Cell (CAR-T cell) therapy product. This multicenter, single-arm, open-label, early exploratory clinical study is designed to evaluate the preliminary safety and efficacy of KSVCBD injection in patients with relapsed or refractory (r/r) multiple myeloma(MM) expressing CD19 and/or BCMA.

Read the detailed description

A structurally modified, third-generation, self-inactivating lentiviral vector was used in KSVCBD injection. This modified vector exhibits reduced immunogenicity and enables efficient T-cell targeting, thereby facilitating the in vivo generation of CD19/BCMA CAR T cells from endogenous T cells. Simultaneously targeting BCMA to eliminate plasma cells producing anti-lentivirus and anti-CD19 scFv antibodies enables repeated infusion. The safety and efficacy of CD19/BCMA dual-target autologous CAR-T therapy for the treatment of r/r MM have already been validated in clinical studies. In this study, dose-escalation research will be conducted to explore the safety and preliminary efficacy of CD19/BCMA dual-target in vivo CAR-T therapy in patients with r/r MM who are positive for CD19 and/or BCMA expression.

Eligibility criteria

Key Inclusion Criteria:

  1. Age 18-75 years (inclusive), any gender.
  2. Subjects must meet the following diagnostic and treatment criteria:

    2.1 According to the IMWG 2014 diagnostic criteria, subjects must have a confirmed diagnosis of multiple myeloma and be in a state at screening, while meeting all of the following conditions:

    • Must have received at least 3 prior lines of MM therapy (including a proteasome inhibitor and an immunomodulatory agent). consecutive cycles of induction chemotherapy, hematopoietic stem cell transplantation, and maintenance therapy are considered as one if no disease progression occurs between these treatments. each line of therapy must consist of at least one complete treatment cycle, unless the best response to that regimen was disease progression.
    • Must have experienced disease progression during or within 12 months after the most recent anti-myeloma therapy. or the subject must have experienced disease progression within the last 6 months and subsequently shown no response to the most recent line of therapy. Lack of response is defined as failure to achieve at least a minimal response (MR) or experiencing disease progression (PD) during treatment.

    2.2 Subjects judged by the investigator to be intolerant to standard therapy may also be included in the study.

  3. Presence of at screening as determined by any of the following criteria:

    • Serum monoclonal paraprotein (M-protein) level ≥ 1.0 g/dL, or urinary M-protein level ≥ 200 mg/24 hours. or
    • For light chain multiple myeloma without measurable lesions in serum or urine: serum immunoglobulin free light chain level ≥ 10 mg/dL and an abnormal serum immunoglobulin κ/λ free light chain ratio.
  4. Positive expression of CD19 and/or BCMA in tumor tissue confirmed by flow cytometry and/or histopathology (previous pathology or flow cytometry diagnosis of CD19 and/or BCMA in the patient, as confirmed by the investigator, is acceptable). For subjects who have previously received anti-CD19 and/or anti-BCMA therapy, a tumor should be performed to confirm current positive expression of CD19 and/or BCMA.
  5. Toxicities from any prior therapy must be stable and have resolved to ≤ Grade 1 (excluding hematologic toxicities and clinically insignificant toxicities such as alopecia).
  6. (ECOG) performance status ≤ 2.

Key Exclusion Criteria:

  1. Expected survival \< 3 months.
  2. History of or concurrent active . Exceptions include: carcinoma in situ of the cervix that has been cured or with no recurrence for at least 3 years, non-invasive basal cell or squamous cell skin cancer, locally advanced prostate cancer that has received curative treatment, or ductal carcinoma in situ after radical surgery.
  3. Prior hematopoietic stem cell transplantation (allo-HSCT) or autologous HSCT within 3 months prior to KSVCBD infusion.
  4. Diagnosis of plasma cell leukemia, Waldenström's macroglobulinemia, POEMS syndrome, or primary AL amyloidosis.
  5. Presence of or symptoms of CNS metastasis.
  6. Receipt of anti-tumor therapy that is still within 5 half-lives prior to the planned KSVCBD infusion.
  7. Presence of uncontrolled active infections.
  8. Positive for (HIV) antibody, positive for Treponema pallidum antibody, positive for surface antigen (HBsAg) or positive for hepatitis B core antibody (HBcAb) with detectable peripheral blood HBV DNA, or positive for virus (HCV) antibody with detectable HCV RNA. except for infections that the investigator judges can be prevented or controlled with medication.
  9. Known active disease requiring systemic treatment.
  10. Known severe allergy to the study drug or any of its components.
  11. Pregnant or breastfeeding women.
  12. Receipt of a within 6 weeks prior to enrollment.
Terms in these criteria, in plain language(13)

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.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

HIV

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 tests

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 tests

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.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

Started Sep 2026 (actual). Primary completion is estimated for Dec 2028, 27 months after the start.

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 27 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.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 15, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
