Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Patient who permanently discontinued avalglucosidase alfa in a previous clinical study

Other illness

  • Patient with life-threatening hypersensitivity (anaphylactic reaction) to one of avalglucosidase alfa's excipients.
  • The patient has clinically significant organic disease (with the exception of symptoms relating to Pompe disease), including clinically significant cardiovascular, hepatobiliary, pulmonary, neurologic, or renal disease, or other medical condition, serious intercurrent illness, or extenuating circumstance that, in the opinion of the Investigator, precludes participation in the study or potentially decreases survival.

Other

  • Pregnant or breastfeeding female patient
  • The patient is concurrently participating in another clinical study of investigational treatment.
  • The patient, in opinion of the Investigator, is unable to comply with the requirements of the study.
  • Individuals accommodated in an institution because of regulatory or legal order; prisoners, or patients who are legally institutionalized.
    • The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

Who the study is looking for

  • Patient with LOPD or IOPD who has previously completed Study EFC14028, LTS13769, or ACT14132 in France, and reimbursement for avalglucosidase alfa is not yet granted in France.
  • The patient and/or their parent/legal guardian is willing and able to provide signed informed consent, and the patient, if \<18 years of age, is willing to provide assent if deemed able to do so.
  • The patient (and patient's legal guardian if patient is \<18 years of age) must have the ability to comply with the clinical protocol.
  • The patient, if female and of childbearing potential, must have a negative pregnancy test result \[urine beta-human chorionic gonadotropin (β-HCG)\] at enrollment.
  • Sexually active female patients of childbearing potential and male patients are required to practice true abstinence in line with their preferred and usual lifestyle or to use 2 acceptable effective methods of contraception.
