Brief Summary:
This long-term follow-up study will continue to evaluate the long-term safety and efficacy of SPK-8011 in males with hemophilia A, who have received a single intravenous administration of SPK-8011 in any Spark-sponsored SPK-8011 study.

Condition or disease Intervention/treatment
Hemophilia A Genetic: SPK-8011

Detailed Description:
This study will follow patients with hemophilia A, who have received a single intravenous administration of SPK-8011 in any prior Spark-sponsored SPK-8011 study. Subjects will be followed for up to a total of 5 years post infusion (including the time on the dosing study).

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Incidence of FVIII Inhibitors [ Time Frame: 4 years ]
    Incidence of FVIII Inhibitors

  2. Incidence of all adverse events [ Time Frame: 4 years ]
    Incidence of all adverse events

  3. Incidence(s) of new or exacerbation of adverse events of interest [ Time Frame: 4 years ]
    Such as: malignancies, neurologic, rheumatologic or other autoimmune, or hematologic disorders

  4. Annual bleeding rate [ Time Frame: 4 years ]
    Annual bleeding rate

  5. FVIII activity levels [ Time Frame: 4 years ]
    FVIII activity levels

  6. Total FVIII consumption [ Time Frame: 4 years ]
    Total FVIII consumption

  7. Number of FVIII infusions [ Time Frame: 4 years ]
    Number of FVIII infusions


Secondary Outcome Measures :
  1. Joint Health Assessment [ Time Frame: 4 years ]
    Assessment of joint health for six index joints using a modified Hemophilia Joint Health Score (HJHS). The HJHS is a physical examination assessment tool, that measures joint health in the domain of body structure and function (i.e. impairment), of the joints most commonly affected by bleeding in hemophilia: the knees, ankles, and elbows

  2. Target Joint Assessment [ Time Frame: 4 years ]
    Investigator assessment of bleeding in target joints (e.g., hip, elbow, wrist, shoulder, knee, and ankle)

  3. Haem-A-QoL [ Time Frame: 4 years ]
    Quality-of-life (QoL) assessment

  4. EQ-5D-5L [ Time Frame: 4 years ]
    Quality-of-life (QoL) assessment

  5. Activities Assessments [ Time Frame: 4 years ]
    Hemophilia Activities List

  6. Health Economics Assessment [ Time Frame: 4 years ]
    Collection of information including number of hospitalizations, emergency room visits, physician visits and work/school days missed
