Study summary

This is a non-interventional, observational, global, multicenter, study describing participant characteristics, clinical outcomes, and event rates in participants with propionic acidemia (PA).

Read the detailed description

Data will be abstracted through medical record review ensuring inclusion only of data from participants meeting all the inclusion criteria and none of the censoring criteria. Data will be collected retrospectively from study sites, including medical clinics, hospitals and academic medical centers.

Study population

Individuals of a minimum age of 2 years with confirmed diagnosis of PA.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

Participants' medical records are eligible for abstraction only if all of the following criteria apply:

  • Confirmed diagnosis of PA based on diagnosis by molecular genetic testing (propionyl-CoA carboxylase subunitα[PCCA] and/or propionyl-CoA carboxylase subunitβ[PCCB] mutations).
  • Participant provided (and assent, as applicable).
  • Medical records with sufficient data to support medical encounter for CEC adjudication (MEA adjudication) must be available dating back to birth or 01 January 2015, whichever occurs later. Participants born prior to 2015 will require additional information to confirm eligibility.
  • Experienced at least one MDE in the 24 months preceding the Index Date or experienced at least 3 MDEs within any one 12-month retrospective review period (based on Index Date) dating back to birth or 01 January 2015, whichever occurs later.
  • Must have a confirmed age (months) of disease onset (early or late, where early is defined as the neonatal period).
  • Participants who meet any of the censoring criteria listed below may be enrolled into the study if they have a minimum of 2 years of data available for abstraction prior to meeting the censoring criteria and they meet all inclusion criteria based on the data available for abstraction.

Censoring Criteria:

Participants medical records meeting the following censoring criterion will not be abstracted:

  • Participation in a clinical study of any agent.
  • Received gene therapy treatment
  • Confirmed organ transplantation
  • Investigator is no longer able to obtain relevant clinical information of the participant.
  • Death

Exclusion criteria

Exclusion Criteria:

Participant's medical records will not be eligible for abstraction if the participant meets the following exclusion criteria:

- Participation (prior or ongoing) in clinical study mRNA-3927-P101 (NCT04159103) or mRNA-3927-P101-EXT (NCT05130437).

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 5, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
