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

  1. Type I SMA, defined by bi-allelic mutations in the SMN1 gene.
  2. Clinical history and signs are consistent with type I SMA, such as hypotonia, delayed motor function development, and poor head control.
  3. On the day of administration, the age of the subjects do not exceed 180 days after birth.

Exclusion criteria

Exclusion Criteria:

  1. Pulse oximetry \< 96% saturation at screening while the patient is awake or asleep without any supplemental oxygen or respiratory support.
  2. Weight-for-age below the 3rd percentile for the same sex and age based on WHO Child Growth Standards.
  3. Active viral infection.
  4. In the presence of other severe infections or diseases that require systemic anti-infection treatment.
  5. Known allergy to prednisolone, other , or SKG0201's .
  6. abnormal laboratory values prior to administration.
  7. Previously used Zolgensma or other SMA gene therapy drugs, or currently participating in other SMA clinical studies on therapeutic drugs.
  8. Having previously undergone major surgery or expected to undergo major surgery during the study assessment period.
Terms in these criteria, in plain language(3)

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.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

What researchers measure

Primary outcomes

  1. Incidence of AEs and SAEs

    AEs: adverse events; SAEs: serious Adverse events

    Time frame: to 18 months of age

  2. Incidence and characteristics of DLT

    DLT: dose-limiting toxicity

    Time frame: 4 weeks

Secondary outcomes

  1. Survival rate

    Survival is defined as avoidance of either death or permanent ventilation.

    Time frame: 14 months of age

  2. CHOP-INTEND score changes from baseline

    CHOP-INTEND (Children's hospital of Philadelphia Infant Test of Neuromuscular Disorders) score ranges from 0 to 64 with higher scores indicating higher motor function.

    Time frame: to 18 months of age

  3. The proportion of subjects whose CHOP-INTEND score reached 40 or above

    CHOP-INTEND (Children's hospital of Philadelphia Infant Test of Neuromuscular Disorders) score ranges from 0 to 64 with higher scores indicating higher motor function.

    Time frame: to 18 months of age

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.
