Long-Term Safety and Efficacy of Spark-Sponsored Gene Therapies in Males With Hemophilia A

November 26, 2024 updated by: Spark Therapeutics, Inc.

A Multi-Center Evaluation of the Long-Term Safety and Efficacy of Spark-sponsored Gene Therapies in Males With Hemophilia A

This long-term follow-up study will continue to evaluate the long-term safety and efficacy of SPK-8011 and SPK-8016 in males with hemophilia A, who have received a single intravenous administration of SPK-8011 or SPK-8016 in any Spark-sponsored SPK-8011 or SPK-8016 study.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will follow patients with hemophilia A, who have received a single intravenous administration of SPK-8011 or SPK-8016 in any prior Spark-sponsored SPK-8011 or SPK-8016 study. Participants will be followed for up to a total of 10 years post infusion (including the time on the dosing study).

Study Type

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Males with hemophilia A, who received a single intravenous administration of SPK-8011 or SPK-8016 in any Spark-sponsored study.

Description

Inclusion Criteria

Participants are eligible to be included in the study only if all of the following criteria apply:

  1. Have received a single intravenous administration of SPK-8011 or SPK-8016 in either Study SPK-8011-101 or SPK-8016-101, respectively.
  2. Understand the purpose and risks of the study and provide signed and dated informed consent before undergoing any study-specific procedures.

Exclusion Criteria

Participants are excluded from the study if any of the following criteria apply:

1.Unable or unwilling to comply with the schedule of visits and study assessments as described in this study protocol.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame

Time Frame: Up to 9 years
Up to 9 years
Number of Participants with Adverse Events of Special Interest (AESIs)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
