First-in-Human Study for the Safety and Evaluation of Two 4R Tau Ligands as Potential PET Radioligands for Imaging Tau Protein in the Brain

Testing new brain imaging tools for tau protein safety.

Recruiting
18-80 years
All
Phase 0

This study is testing two new imaging drugs, [18F]ABBV-964i and [18F]ABBV-965i. These drugs are used with PET scans, a special type of brain scan, to help doctors see tau protein buildup in the brain. Tau protein buildup is linked to a rare disease called Progressive Supranuclear Palsy (PSP), which affects movement and thinking.

The study is checking if these drugs are safe and if they work well for showing tau in the brain. It also looks at how these drugs move in the body and the amount of radiation they produce. This information may help create better tools for diagnosing PSP and understanding its progress.

  • Study involves multiple visits for PET scans, blood tests, and an optional MRI scan.
  • Participants can be healthy adults or those with PSP, aged 18-80 for healthy volunteers and 40-80 for PSP patients.
  • Safety checks include vital signs, blood tests, and heart monitoring.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
