Brief Summary:
This is a Phase II study to determine the efficacy and safety of PHE885, a BCMA-directed CAR-T cells, manufactured with a new process. CAR-T cells will be investigated as a single agent in relapsed and refractory multiple myeloma

Condition or disease Intervention/treatment Phase
Multiple Myeloma Biological: PHE885 Phase 2

Detailed Description:

This clinical trial employs an open label, single arm, multi-center design with primary analysis testing overall response rate ( ORR), including one interim analysis for futility and one interim analysis for efficacy.

The trial population includes adult patients with relapsed and refractory multiple myeloma ( MM) who failed 3 or more different prior lines of therapy, including failing an immunomodulatory drug (IMiD), a proteasome inhibitor (PI) and an anti-CD38 (cluster of differentiation 38) monoclonal antibody (mAb) and who have measurable disease at enrollment per IMWG criteria . In addition, patients must be refractory to the last line of therapy

The trial will enroll 100 efficacy evaluable adult patients with relapsed and refractory MM (efficacy evaluable means participants injected with a PHE885 product that met all release specifications).

Patients will be followed for acute and intermediate safety and efficacy within this trial for a minimum of 2 years before being transferred to the long-term follow-up trial. A long-term post-study follow-up for lentiviral vector safety will be offered under a separate destination protocol for 15 years post injection per health authority guidelines.

Primary Outcome Measures :
  1. Overall response rate (ORR) per Independent Review Committee (IRC) [ Time Frame: 24 Months ]
    Percentage of patients with best overall response (BOR) of either stringent complete response (sCR), complete response (CR), very good partial response (VGPR), partial response (PR) according to the International Myeloma Working Group (IMWG) criteria'


Secondary Outcome Measures :
  1. Complete response rate (CRR) [ Time Frame: 24 Months ]
    Percentage of patients with BOR of sCR or CR according to the IMWG criteria

  2. Time to response [ Time Frame: 24 Months ]
    Time form PHE885 infusion to the date of first documented response (PR or better)

  3. Duration of Response (DOR) [ Time Frame: 24 Months ]
    Time from first documented response (PR or better) until relapse or death due to any cause

  4. Progression free survival (PFS) [ Time Frame: 24 Months ]
    Time from PHE885 infusion until progression or death due to any cause

  5. Time to next anti-myeloma treatment (TTNT) [ Time Frame: 24 Months ]
    Time from PHE885 infusion until start of new anti-myeloma therapy or death due to any cause

  6. Overall Survival (OS) [ Time Frame: 24 Months ]
    Time from PHE885 infusion until death due to any cause

  7. Patient Reported Outcomes (PRO): EORTC-QLQ-C30 [ Time Frame: 24 months ]
    PROs as measured by European Organization for Research and Treatment of Cancer Quality-of-Life questionnaire (EORTC-QLQ-C30) Questionnaire will be used as a measure of health-related quality of life.

  8. Patient Reported Outcomes (PRO): EQ-5D-5L Health Questionnaire [ Time Frame: 24 months ]
    PROs as measured by EuroQoL Group EQ-5D-5L Health Questionnaire is a standardized measure of health status developed by the EuroQol Group in order to provide a simple, generic measure of health for clinical and economic appraisal.

  9. Patient Reported Outcomes (PRO): EORTC-QLQ-MY20 [ Time Frame: 24 months ]
    PROs as measured by EORTC-QLQ-MY20 is a 20-item myeloma module intended for use among patients varying in disease stage and treatment modality.

  10. Rate of minimal residual disease (MRD) Negativity [ Time Frame: 24 Months ]
    Percentage of patients who attain MRD negative status defined at sensitivity level of 1 in 10^5 nucleated cells by next generation sequencing (NGS)

  11. Durability of MRD negativity [ Time Frame: 24 Months ]
    Time from the start of undetectable MRD to the time of reappearance of detectable MRD

  12. PHE885 manufacturing success rate [ Time Frame: 24 Months ]
    Percentage of enrolled patients for whom PHE885 product was manufactured that met all release specifications

  13. Manufacturing turnaround time [ Time Frame: 24 months ]
    Time from pick of cryopreserved material at the clinic or hospital until return to the clinical or hospital

  14. Immunogenicity to PHE885 [ Time Frame: 24 Months ]
    Summary of pre-existing and treatment-induced immunogenicity (cellular and humoral) of PHE885

  15. Transgene of PHE885 concentrations over time in peripheral blood and bone marrow [ Time Frame: 24 Months ]
    As determined by quantitative polymerase chain reaction (qPCR)

  16. Cellular kinetics parameter: Cmax [ Time Frame: 24 Months ]
    The maximum transgene level at Tmax

  17. Cellular kinetics parameter: Tmax [ Time Frame: 24 Months ]
    The time to peak transgene level

  18. Cellular kinetics parameter: AUC [ Time Frame: 24 months ]
    The Area under the curve of the transgene level
