Study summary

This is a global, prospective, multi-center study that is designed to assess the long-term safety and efficacy of OAV101 in patients who participated in an OAV101 clinical trial. The assessments of safety and efficacy in Study COAV101A12308 will continue for 5 years after enrollment in this study.

Read the detailed description

The study is comprised of a Baseline Visit and 2 Follow-up Periods. For Follow-up Periods 1 and 2, which includes Baseline through Year 5 visits, assessments will be performed at the Investigational site. For the first 2 years (Follow-up Period 1), visits will occur every 6 months. For Years 3 to 5 (Follow-up Period 2) follow-up visits will be conducted annually. All patients will enter the study at the baseline visit and continue for 5 years.

Study arms

  • Experimental
    Intravenous (IV) & Intrathecal (IT) Onasemnogene Abeparvovec

    Patients who received OAV101 IT or OAV101 IV in clinical trials (COAV101A12306, COAV101B12301 and COAV101B12302)

    Biological: onasemnogene abeparvovec

Interventions

  • Biologicalonasemnogene abeparvovec

    Onasemnogene abeparvovec is a non-replicating recombinant adeno-associated virus serotype 9 containing the human survival motor neuron gene under the control of the ytomegalovirus enhancer/chicken β-actin-hybrid promoter. Onasemnogene abeparvovec is administered as a one-time intravenous (IV) infusion or intrathecal (IT) injection. Dosage determined by participant weight.

    Also known as: Zolgensma

What researchers measure

Primary outcomes

  1. Number of participants with treatment-emergent serious adverse events (SAEs)

    An SAE is defined as any adverse event \[appearance of (or worsening of any pre-existing)\] undesirable sign(s), symptom(s), or medical conditions(s) which meets any one of the following criteria: * fatal * life-threatening * results in persistent or significant disability/incapacity * constitutes a congenital anomaly/birth defect, fetal death or congenital abnormality or birth defect * requires in-patient hospitalization or prolongation of existing hospitalization, unless hospitalization is for routine treatment or monitoring of the studied indication, not associated with any deterioration in condition * is medically significant, e.g. defined as an event that jeopardizes the participant or may require medical or surgical intervention to prevent one of the outcomes listed above

    Time frame: Up to Year 5

  2. Number of participants with treatment emergent Adverse Events of Special Interest (AESI)

    The following are important identified and important potential risks (AESI) associated with OAV101: Hepatotoxicity, Transient Thrombocytopenia, Cardiac adverse events, Sensory abnormalities suggestive of ganglionopathy, and Thrombotic microangiopathy. These will be assessed by the investigator.

    Time frame: Up to Year 5

Secondary outcomes

  1. The number of participants demonstrating each developmental milestone according to the Developmental Milestone Checklist

    The Developmental Milestone Checklist is a sponsor created list of items using relevant definitions obtained from World Health Organization Multicentre Growth Reference Study (WHO-MGRS). These will be assessed via the milestone checklist, formed of 6 yes/no questions. The developmental milestones are: sitting with support, hands-and-knees crawling, standing with assistance, walking with assistance, standing alone and walking alone. A yes response indicates that the patient reached a particular development milestone.

    Time frame: Up to Year 5

  2. The number of participants demonstrating maintenance of each developmental milestone according to the Developmental Milestone Checklist

    The Developmental Milestone Checklist is a sponsor created list of items using relevant definitions obtained from World Health Organization Multicentre Growth Reference Study (WHO-MGRS). These will be assessed via the milestone checklist, formed of 6 yes/no questions. The developmental milestones are: sitting with support, hands-and-knees crawling, standing with assistance, walking with assistance, standing alone and walking alone. A yes response indicates that the patient reached a particular development milestone.

    Time frame: Up to Year 5

  3. Change from Baseline in the Hammersmith Functional Motor Scale - Expanded (HFMSE) total score

    The HFMSE is a validated SMA specific assessment devised for use in children with SMA to give objective information on motor ability and clinical progression. The HFMSE contains 33 items rated from 0 (unable to perform) to 2 (performs without modification/adaptation/compensation). Total scores range from 0-66. Higher scores indicate higher levels of motor ability.

    Time frame: Up to Year 5

  4. Change from Baseline in the Revised Upper Limb Module (RULM) total score

    The RULM is a validated SMA specific assessment of motor performance in the upper limbs from childhood through adulthood in ambulatory and non-ambulatory individuals with SMA. The scale consists of 19 scorable items: 18 items scored on 0 (unable) to 2 (full achievement) scale, and one item that is scored from 0 (unable) to 1 (able). Total scores range from 0-37 points. Higher scores reflect higher level of motor ability.

    Time frame: Up to Year 5

  5. Systolic and diastolic blood pressure (mmHg)

    Time frame: Up to Year 5

  6. Number of patients with potentialy clinically significant vital sign findings - Respiratory Rate (breaths/min)

    Time frame: Up to Year 5

  7. Number of patients with potentialy clinically significant vital sign findings -Pulse Rate (beats/min)

    Time frame: Up to Year 5

  8. Number of patients with potentialy clinically significant vital sign findings -Temperature (Degrees Celsius)

    Time frame: Up to Year 5

  9. Number of patients with potentialy clinically significant vital sign findings -Oxygen saturation level (%).

    Oxygen saturation is the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated+saturated) in the blood and then multiplied by 100.

    Time frame: Up to Year 5
