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   44338   clinical trials with a EudraCT protocol, of which   7368   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.

    - Characterize the changes from baseline in plasma 2-methylcitric acid (2-MC) levels after single and repeated administrations of mRNA-3705
    - Characterize the pharmacokinetics (PK) of human MUT (hMUT) messenger ribonucleic acid (mRNA) after single and repeated administrations of mRNA-3705

    E.3Principal inclusion criteria
    1. Participant is ≥ 1 year of age at the time of informed consent/assent.
    2. Participant has a body weight of ≥ 11.0 kg at the Screening Visit
    3. Participant has a diagnosis of isolated MMA due to MUT deficiency confirmed by molecular genetic testing. (see guidance in Section 8.1.1 for participants < 23.3 kg).
    4. Participant has a serum/plasma vitamin B12 level equal to or above the lower limit of normal (based on laboratory reference range) confirmed in the Screening Period. For those participants found to have an elevated serum/plasma vitamin B12 level, the participant may enter if, in the opinion of the Investigator, the cause of the elevation is secondary to B12 supplementation.
    5. Participant or his/her legally authorized representative is willing and able to provide informed consent and/or assent as mandated by local regulations and willing and able to comply with study-related assessments.
    6. Sexually active females of childbearing potential and
    sexually active males of reproductive potential agree to
    use a highly effective method of contraception during the study and for 3 months after the last administration of study drug (Section 11.4).
    7. Participants with parameters that indicate MMA clinical severity as described in Section 11.2.3.
    E.4Principal exclusion criteria
    1. Participant has a diagnosis of isolated MMA cb1A, cb1B, or cb1D enzymatic subtypes or methylmalonyl-CoA
    epimerase deficiency or combined MMA with homocystinuria.
    2. Participant has any individual laboratory abnormalities
    achieving exclusionary thresholds defined in Table 16.
    3. Participant has previously received gene therapy for the treatment of MMA.
    4. Participant has an eGFR <30mL/min/1.73m2, as estimated by the Schwartz formula for participants<18years of age (Schwartz et al 2009), or by the Chronic Kidney Disease Epidemiology Collaboration creatinine-based formula for participants ≥ 18 years of age (Inker et al 2021), or receives long-term dialysis.
    5. Participant has a corrected QT interval > 480 ms using
    Bazett’s correction.
    6. For female participants of reproductive potential, the
    participant has a positive pregnancy test at the Screening
    Visit.
    7. Participant is pregnant or breastfeeding.
    8. Participant has a history of organ transplantation.
    9. Participant has a history of hypersensitivity to any
    components of the study drug.
    10. Participant has a history of hypersensitivity to
    acetaminophen/paracetamol and/or ibuprofen or
    H1/H2receptor blockers.
    11. Participation in another clinical study of another investigational agent within 30 days before study entry or within 5 elimination half-lives of the
    investigational agent, whichever is longer.
    12. Participant has undergone a major surgical procedure within 30 days before the Screening Visit (excludes central line, port, or feeding tube placement).
    13. Participant has new uses or adjustments in dose within the last 2 weeks to antibiotic therapy used to reduce propionate production. Any participant whose new or adjusted dose in antibiotics conflicts with the rules described above may enter the Treatment Period after stabilization of the antibiotic
    regimen and reconfirmation of study eligibility.
    14. Participant has an active, unstable or clinically significant medical condition not related to MMA or history of noncompliance that, in the Investigator’s opinion, could potentiate the risk while participating in this study, interfere with the interpretation of study results or limit
    the participant’s participation in the study. This may include, but is not limited to, history of relevant food or drug allergies; history of cardiovascular, central nervous, gastrointestinal, or infectious disease; history of clinically significant pathology; and/or history of cancer.
    15. Participant has received COVID-19 vaccination (generally 2 doses or a booster) within 6 weeks between their last COVID-19 vaccination dose and first study drug administration.
    16. Participant has any individual vital sign abnormalities achieving exclusionary thresholds as defined in Table 17
    .17. Participant has a history of anaphylaxis/anaphylactoid reaction or severe hypersensitivity with infusions.
