About this study
Official title: A Phase 2, Open-label, Multicenter Multi-cohort Study to Evaluate the Efficacy and Safety of Anitocabtagene Autoleucel in Participants With Newly Diagnosed Multiple Myeloma
The goal of this clinical trial is to learn if anitocabtagene autoleucel following induction therapy works to treat adult participants with newly diagnosed multiple myeloma. The main objectives of this clinical trial are:
- To determine the incidence and severity of all adverse events (AEs).
- To determine the proportion of patients achieving undetectable minimal residual disease (uMRD) negative-CR rate (minimum 10 to -5) at 12 months (+/- 3 months) after enrollment.
Participants will receive induction therapy with a quadruplet regimen including a proteasome inhibitor (Bortezomib [V]), immunomodulatory drug (Lenalidomide [R]), dexamethasone [d] and anti-CD38 monoclonal antibody (Daratumumab [D] or Isatuximab [Isa]) followed by anitocabtagene autoleucel. Participants in Cohorts A and B will receive lenalidomide maintenance therapy following infusion with anitocabtagene autoleucel.
Read the detailed description
Approximately 30 participants will be enrolled to receive induction therapy followed by a single dose of anitocabtagene autoleucel (~ 10 patients treated at target treatment dose per cohort). Participants will be distributed in 3 cohorts of treatment (A, B and C). Participants of cohort A will be transplant eligible while participants of cohorts B and C will not be planned to receive transplantation:
- Induction therapy:
- Cohort A: will consist of a total of 6 cycles D-VRd (28-day cycles); 3 cycles followed by leukapheresis for T-cell collection to manufacture anitocabtagene autoleucel, followed by 3 additional cycles.
- Cohort B: will consist of a total of 4 cycles Isa-VRd (42-day cycles); 2 cycles followed by leukapheresis for T-cell collection to manufacture anitocabtagene autoleucel, followed by 2 additional cycles.
- Cohort C: will consist of a total of 4 cycles Isa-VRd (42-day cycles); 2 cycles followed by leukapheresis for T-cell collection to manufacture anitocabtagene autoleucel, followed by 2 additional cycles.
- Bridging Therapy: Bridging therapy will not be required because the leukapheresis and manufacturing will be planned during the induction phase to allow the availability of anitocabtagene autoleucel at the end of the induction therapy.
- Lymphodepleting Chemotherapy: Chemotherapy regimen consisting of cyclophosphamide 300 mg/m2/day and fludarabine 30 mg/m2/day will be administered intravenously (IV) daily for 3 days (Days -5 through -3) before administration of anitocabtagene autoleucel. The fludarabine dose may be adjusted for renal function. Initiation of the 3-day lymphodepleting chemotherapy regimen on Day -7 or Day -6 prior to the anitocabtagene autoleucel infusion on Day +1 is permitted.
- Anitocabtagene Autoleucel: Treatment consists of a single infusion of anitocabtagene autoleucel administered intravenous (IV) on Day 1 at a target dose of 115 x 10e6 (± 10 x 10e6) CAR+ viable T cells.
- Maintenance Therapy:
Cohorts A and B will receive maintenance therapy which will consist of lenalidomide 10 mg daily (days 1 to 28 of repeated 28-day cycle) for 2 years or until unacceptable toxicity, progression as per IMWG criteria, participant withdrawal of consent, death, or study completion, whichever occurs first. If any of these circumstances occur participant maintenance will end. After 3 cycles of lenalidomide maintenance, the dose can be increased to 15 mg orally once daily if tolerated.

MRD measured by Next Generation Flow Cytometry. Serum and/or urine monoclonal protein alone or with clinical features suggestive of progression including CRAB (C, hypercalcemia; R, renal failure; A, anemia; B, bone disease) symptoms.
Measured: 3 years
Undetectable MRD at 10e-6 (0.0001%)
MRD measured by Next Generation Flow Cytometry. Undetectable MRD at 10e-6 (10 elevated to -6, which is the same as 0.0001%) means no presence of multiple myloma cells within 1,000,000 cells analyzed by flow cytometry
Measured: 3 years
Overall Response Rate (ORR) per International Myeloma Working Group (IMWG) criteria
ORR is defined as the proportion of participants who achieve a best overall response of at least partial response (PR) or better (sCR, CR, VGPR, or PR) per IMWG criteria.
Measured: 3 years
Duration of Response (DoR)

Overall rate of "imaging plus MRD negative" (using PET/CT per International Myeloma Working Group [IMWG] criteria)
Measured by Fluorodeoxyglucose Positron Emission Tomography-Computerized Tomography (FDG PET-CT) scan using the Deauville score.
The Deauville score is a 5-point grading system used on FDG PET/CT imaging to assess treatment response. It is based on comparing FDG uptake in lesions with uptake in the liver and mediastinum. The Deauville score values are:
- No FDG uptake above background.
- Uptake less than the liver.
- Uptake equal to the liver.
- Uptake moderately greater than the liver.
- Uptake markedly greater than the liver, typically 2-3 times greater.
Measured: 3 years
Expansion and persistence of anitocabtagene autoleucel in peripheral blood
Measured by Next Generation Flow Cytometry.
Measured: 2.5 years

|---|---|---|
| Cohort A | Experimental | Drug: Daratumumab, Drug: Bortezomib, Drug: Lenalidomide, Drug: Cyclophosphamide, Drug: Fludarabine, Drug: Anitocabtagene AutoleucelCohort A participants will be transplant eligible. Cohort A participants will receive induction with 6 cycles D-VRd. After induction, lymphodepleting chemotherapy will be administered consisting of cyclophosphamide 300 mg/m2/day and fludarabine 30 mg/m2/day intravenous (IV) daily for 3 days before administration of anitocabtagene autoleucel. Initiation of the 3-day lymphodepleting chemotherapy regimen on Day -7 or Day -6 prior to the anitocabtagene autoleucel infusion on Day +1 is permitted. After lymphodepletion, participants will receive a single infusion of anitocabtagene autoleucel administered IV. After CAR T-cell infusion, cohort A participants will receive maintenance therapy with lenalidomide 10 mg daily for 2 years or until unacceptable toxicity, progression as per IMWG criteria, participant withdrawal of consent, death, or study completion, whichever occurs first. |
| Cohort B | Experimental | Drug: Isatuximab, Drug: Bortezomib, Drug: Lenalidomide, Drug: Cyclophosphamide, Drug: Fludarabine, Drug: Anitocabtagene AutoleucelCohort B participants will not be transplant eligible. Cohort B participants will receive induction with 4 cycles Isa-VRd. After induction, lymphodepleting chemotherapy will be administered consisting of cyclophosphamide 300 mg/m2/day and fludarabine 30 mg/m2/day IV daily for 3 days before administration of anitocabtagene autoleucel. Initiation of the 3-day lymphodepleting chemotherapy regimen on Day -7 or Day -6 prior to the anitocabtagene autoleucel infusion on Day +1 is permitted. After lymphodepletion, participants will receive a single infusion of anitocabtagene autoleucel administered IV. After CAR T-cell infusion, cohort B participants will receive maintenance therapy with lenalidomide 10 mg daily for 2 years or until unacceptable toxicity, progression as per IMWG criteria, participant withdrawal of consent, death, or study completion, whichever occurs first. |
| Cohort C | Experimental | Drug: Isatuximab, Drug: Bortezomib, Drug: Lenalidomide, Drug: Cyclophosphamide, Drug: Fludarabine, Drug: Anitocabtagene AutoleucelCohort C participants will not be transplant eligible. Cohort C participants will receive induction with 4 cycles Isa-VRd; 2 cycles followed by leukapheresis for T-cell collection to manufacture anitocabtagene autoleucel, followed by 2 additional cycles. After induction, lymphodepleting chemotherapy will be administered consisting of cyclophosphamide 300 mg/m2/day and fludarabine 30 mg/m2/day IV daily for 3 days (Days -5 through -3) before administration of anitocabtagene autoleucel. The fludarabine dose may be adjusted for renal function. Initiation of the 3-day lymphodepleting chemotherapy regimen on Day -7 or Day -6 prior to the anitocabtagene autoleucel infusion on Day +1 is permitted. After lymphodepletion, participants will receive a single infusion of anitocabtagene autoleucel administered IV with a dose of 115 x 10e6 (± 10 x 10e6) CAR+ viable T cells.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 25 inclusion and 33 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 1 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 10 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Carmen López-Carrero (0034 699 835 437, carmen@fundacionpethema.es), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence and severity of all adverse events (AEs) (time frame: 3 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Aug 2025.
