BCMA-målrettede LCAR-BCDR-celler hos patienter med recidiverende/refraktær myelomatose
Et klinisk fase I-studie til evaluering af sikkerheden, tolerabiliteten og effektiviteten af BCMA-målrettet LCAR-BCDR-celleprodukt hos patienter med recidiverende/refraktær myelomatose
This is a prospective, single-arm, open-label, dose-finding and dose-expansion study that evaluates the safety, tolerability, PK, and anti-tumor efficacy of LCAR-BCDR cell preparations in relapsed/refractory multiple myeloma subjects who received adequate standard therapy.

Detaljeret beskrivelse
The research plan stipulates that "four dose groups will be conducted, namely 30×10^6, 100×10^6, 200×10^6, and 400×10^6". The research team held a SET meeting and decided to increase the dose escalation to 600×10^6 and 800×10^6, and obtained ethical approval from all sites.

Beskrivelse
Inclusion Criteria:
- The subject voluntarily participates in the clinical study; Fully understand and be Informed of the study and sign the Informed consent (Informed Consent Form, ICF); Willing to follow and able to complete all test procedures; Informed consent must be obtained before initiating any tests or procedures related to the study that are not part of the standard treatment of the subject's disease;
- Subjects ≥ 18 years of age.
- Documented initial diagnosis of MM according to IMWG diagnostic criteria.
- Presence of measurable disease at screening.
- Received a PI and an IMiD (except thalidomide).
- Received at least 3 prior lines of therapy for multiple myeloma, undergone at least 1 complete cycle of treatment for each line, unless progressive disease (PD) was documented by IMWG criteria as the best response to the regimen. Also, subjects refractory or intolerant to any PI and any IMiD in their previous treatment afterwards are eligible.
- Expected survival ≥ 3 months.
- Clinical laboratory values meet screening visit criteria
- Fertile women must be negative using a highly sensitive serum pregnancy test (β human chorionic gonadotropin [β -HCG]) at screening time and before initial treatment with cyclophosphamide and fludarabine;
Exclusion Criteria:
- No response to prior BCMA-targeted CAR-T therapy (except in subjects who relapsed after CR to prior CAR-T treatment).
- Prior treatment with any antibody targeting BCMA.
- Diagnosed or pretreated for an invasive malignancy other than multiple myeloma.
- Prior anti-tumor treatment (before pretreatment) with insufficient washout period.
- Known active, or prior history of central nervous system (CNS) involvement, or clinical signs of membrane/spinal membrane involvement of multiple myeloma.
- Positive of any hepatitis B surface antigen (HBsAg), hepatitis B virus deoxyribonucleic acid (HBV DNA), hepatitis C antibody (HCV-Ab), hepatitis C virus ribonucleic acid (HCV RNA), human immunodeficiency virus antibody (HIV-Ab) at the time of screening.
- Serious underlying medical conditions
- Male subjects who have a birth plan during the study period or within 1 year after the study treatment.
- Female subjects who are pregnant, breast-feeding, or plan to become pregnant during the study period or within 1 year after the study treatment.
- The investigator considered that the subjects were not suitable for any conditions of participation in the study.

Tidsramme |
|---|---|---|
|
Overall Response Rate (ORR)
Tidsramme: Minimum 2 years after LCAR-BCDR infusion (Day 1)
|
The ORR is defined as the percentage of participants who achieve partial response (PR) or better according to international myeloma working group (IMWG) criteria. |
Minimum 2 years after LCAR-BCDR infusion (Day 1)
|
|
Progression-free survival (PFS)
Tidsramme: Minimum 2 years after LCAR-BCDR infusion (Day 1)
|
Progression Free Survival (PFS) is defined as the time from the date of first infusion of the LCAR-BCDR to the first documented disease progression (according to IMWG criteria) or death (due to any cause), whichever occurs first |
Minimum 2 years after LCAR-BCDR infusion (Day 1)
|
|
Overall Survival (OS)
Tidsramme: Minimum 2 years after LCAR-BCDR infusion (Day 1)
|
Overall Survival (OS) is defined as the time from the date of first infusion of LCAR-AIO to death of the subject |
Minimum 2 years after LCAR-BCDR infusion (Day 1)
|
|
Incidence of anti-LCAR-BCDR antibody
Tidsramme: Minimum 2 years after LCAR-BCDR infusion (Day 1)
|
Venous blood samples will be collected to measure LCAR-BCDR positive cell concentrations and the transgenic level of LCAR-BCDR, at the time points when anti-LCAR-BCDR antibody serum samples are evaluated |
