What will happen during the study?

Participation in the ACTiVION-I investigational study lasts about 104 weeks (24 months) and is divided into 3 periods:

1. Screening:

Receive tests and assessments to confirm you qualify for the study, including blood and urine tests, imaging (X-ray and MRI) tests, and questionnaires.

2. Study Therapy:

Receive a single injection of either the investigational study therapy or placebo (2:1 randomization ratio). You will remain at the study clinic for approximately 2 hours afterward so the study team can check your health.

3. Follow-up:

Visit the study clinic for tests and assessments. You will have visits 1 day, 1 week, and 1 month after your injection, and then 6 times over the next 24 months.

4. Long-Term Follow-up:

You will be asked to participate in a long-term safety follow-up study to monitor your progress for up to 15 years. If you do not want to participate in the long-term safety follow-up study, then you will be asked to answer questions about your health annually for 13 years after you receive your investigational study therapy or placebo injection.

Participation in this clinical study is voluntary. You can ask any questions you have and may leave this research study at any time, for any reason.
