Study of ARO-ATXN2 Injection in Adults With Spinocerebellar Ataxia Type 2

To join this study, you must be an adult aged between 18 and 65 years old. You need to have a confirmed diagnosis of Spinocerebellar Ataxia Type 2 (SCA2) and carry a specific genetic marker (at least 33 CAG repeats in the ATXN2 gene), which will be checked from your medical records or a genetic test.

There are also some health conditions that would prevent you from taking part. For instance, if you are pregnant or breastfeeding, you cannot join. People with certain uncontrolled health issues like very high blood pressure, serious heart, liver, or kidney disease, or specific infections like HIV or hepatitis B or C, would not be suitable.

Additionally, if you’ve had stem cell therapy previously, have a learning disability, or any problem that would make a procedure called a 'lumbar puncture' unsafe, you wouldn't be able to participate. If you're a woman who could become pregnant, you would need to agree to use effective birth control during and for some time after the study.

If you decide to take part in this study, you would first go through a screening process to make sure you're eligible. If you are, you would then be randomly assigned to receive either the ARO-ATXN2 injection or a placebo (a dummy injection). This will be a single injection administered through a 'lumbar puncture', which is a procedure where a small needle is inserted into your lower back to deliver the medicine into the fluid around your spinal cord.

After the injection, you would have several follow-up appointments. These visits will involve various tests and checks to monitor your health, look for any side effects, and see how your body is reacting to the treatment. This includes checking your general health, possibly having blood tests, and further assessments of your SCA2 symptoms. The total duration of your involvement in the study would be outlined by the study team.
