Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   44235   clinical trials with a EudraCT protocol, of which   7336   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Eligibility is determined prior to leukapheresis. Subjects must satisfy the following criteria to be enrolled in the study:
    1. Subject is ≥ 18 years of age at the time of signing the informed consent form (ICF).
    2. Documented diagnosis of multiple myeloma
    - Must have received at least 3 prior MM treatment regimens. Note: induction with or without hematopoietic stem cell transplant and with or without maintenance therapy is considered a single regimen.

    - Must have received a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 antibody.
    - Must be refractory to the last treatment regimen. Refractory is defined as documented progressive disease during or within 60 days (measured from the last dose) of completing treatment with the last anti-myeloma drug regimen before study entry.
    3. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
    4. Subjects must have measurable disease, including at least one of the criteria below:
    - Serum M-protein greater or equal to 1.0 g/dL
    - Urine M-protein greater or equal to 200 mg/24 h
    - Serum free light chain (FLC) assay: involved FLC level greater or equal to 10 mg/dL (100 mg/L) provided serum FLC ratio is abnormal
    - Bone marrow plasma cells > 30% of total bone marrow cells
    5. Recovery to Grade 1 or baseline of any non-hematologic toxicities due to prior treatments, excluding alopecia and Grade 2 neuropathy.
    6. Subject must understand and voluntarily sign an ICF prior to any study-related assessments/procedures being conducted.
    7. Subject is willing and able to adhere to the study visit schedule and other protocol requirements within this protocol as well as agrees to continued follow-up for up to 15 years as mandated by the regulatory guidelines for gene therapy trials.
    8. Females of childbearing potential (FCBP (see note 1 below)) must:
    - Have a negative pregnancy test as verified by the Investigator, one negative serum beta human chorionic gonadotropin [β-hCG] pregnancy test result at screening, prior to LD chemotherapy. This applies even if the subject practices true abstinence* from heterosexual contact.
    - Either commit to true abstinence* from heterosexual contact or agree to use, and be able to comply with, effective measures of contraception without interruption, from screening through 1 year following last bb2121 infusion. Contraception methods must include 1 highly effective and 1 additional effective (barrier) method of contraception from screening until at least 12 months following bb2121 infusion and until CAR T cells are no longer present by qPCR on two consecutive tests, whichever occurs last.
    - Agree to abstain from breastfeeding during study participation and for at least 1-year post-bb2121 infusion and until CAR T cells are no longer present by qPCR on two consecutive tests, whichever occurs last.

    Note 1: A female of childbearing potential is a female who: 1) has achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral oophorectomy or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (ie, has had menses at any time in the preceding 24 consecutive months).

    Male subjects must:
    - Practice true abstinence* or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study, even if he has undergone a successful vasectomy. Subjects will be followed from screening until at least 1 year following last bb2121 infusion and until CAR T cells are no longer present by qPCR on two consecutive tests, whichever occurs last.

    * True abstinence is acceptable when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.

    Los sujetos varones deben:
    - Practicar la abstinencia real* o aceptar usar un preservativo durante las relaciones sexuales con mujeres embarazadas o en edad fértil mientras participan en el estudio, incluso si se han sometido a una vasectomía con éxito. Se realizará un seguimiento de los sujetos desde la selección hasta que haya transcurrido, como mínimo, un año desde la última infusión de bb2121 y hasta que los linfocitos T CAR ya no estén presentes en su organismo, verificado mediante dos PCR cuantitativas, lo que ocurra más tarde.
    * La abstinencia real se considera aceptable si es coherente con el estilo de vida habitual preferido por el sujeto. La abstinencia periódica, (p. ej., métodos de Ogino, ovulación, sintotérmico o posovulación) y el coito interrumpido no se consideran métodos anticonceptivos aceptables.

    Because this protocol involves gene transfer, long-term follow-up for lentiviral vector safety will be followed under a separate LTFU protocol, for up to 15 years after bb2121 infusion. Subjects will be followed on the current protocol for myeloma response and disease status for a minimum of 24-months post bb2121 infusion or until documented PD, whichever is longer (or minimum of 6 months for subjects retreated with a second bb2121 infusion). Further details are provided in the protocol.
    Seguim a largo plazo para comprobar la seguridad del vector lentivírico conforme a un protocolo de SLP independiente durante un plazo de hasta 15 años tras la infusión de bb2121. Seguim. de los pacientes en el protocolo actual para determinar la respuesta del mieloma y el estado de la enfermedad durante 24 meses mínimo tras la infusión de bb2121o hasta que se verifique la PE, el plazo que sea mayor (o de un mínimo de 6 meses en el caso de los pacientes que reciban una segunda infusión de bb2121)
