What is this study?
Our overall objective is to obtain an initial assessment of the potential value of using \[18F\]3F4AP for imaging demyelinating diseases such as multiple sclerosis: * Aim 1) Assess the safety of \[18F\]3F4AP in healthy volunteers and subjects with multiple sclerosis (MS). Hypothesis 1: Administration of \[18F\]3F4AP will result in no changes in vitals or other adverse events.
It is , overseen by an independent and licensed medical staff.

Our overall objective is to obtain an initial assessment of the potential value of using \[18F\]3F4AP for imaging demyelinating diseases such as multiple sclerosis: * Aim 1) Assess the safety of \[18F\]3F4AP in healthy volunteers and subjects with multiple sclerosis (MS). Hypothesis 1: Administration of \[18F\]3F4AP will result in no changes in vitals or other adverse events. * Aim 2) Assess the pharmacokinetics of a bolus infusion of \[18F\]3F4AP in humans including healthy volunteers and MS patients. Hypothesis 2: the pharmacokinetics of \[18F\]3F4AP at the whole brain level will be similar in controls and MS subjects. The kinetics in demyelinated lesions will be slower than in healthy control areas. * Aim 3) Assess the reproducibility of \[18F\]3F4AP in humans. Hypothesis 3: the test/retest variability of \[18F\]3F4AP within the same subject will be lower than 10%. * Aim 4) Correlate MR brain images with \[18F\]3F4AP PET brain images. Hypothesis 4A: all the lesions seen on the MRI will show increased signal (VT or SUV) on the PET images. Hypothesis 4B: some of the lesions on the MRI will show increased signal (VT or SUV) on the PET but not all. * Aim 5) Correlate \[18F\]3F4AP PET signal with neuropsychological testing in people with MS. Hypothesis 5: increased PET signal (VT or SUV) will correlate with impaired Single Digit Modality Test (SDMT) scores. * Aim 6) Correlate \[18F\]3F4AP PET signal with EDSS score in people with MS. Hypothesis 6: increased PET signal (VT or SUV) will correlate with higher EDSS scores.
Are you a good fit?

What to expect, step by step
- 1
Usually a few weeks
The study team checks whether the study is a good fit for you, with a visit and sometimes lab tests. You can ask any questions before deciding.
- 2
Treatment
If you join and choose to continue, you receive the study treatment and are watched closely by medical staff.
- 3
Follow-up
After treatment, the team checks on your health and confirms the visit schedule with you. You can leave the study at any point.
Has this treatment been tested before?
This is an early-stage study. The treatment has gone through laboratory and preliminary testing before being studied in people here.
What you need to know before you apply
What is this study testing?+
Our overall objective is to obtain an initial assessment of the potential value of using \[18F\]3F4AP for imaging demyelinating diseases such as multiple sclerosis: * Aim 1) Assess the safety of \[18F\]3F4AP in healthy volunteers and subjects with multiple sclerosis (MS). Hypothesis 1: Administration of \[18F\]3F4AP will result in no changes in vitals or other adverse events.
Is it safe? Who makes sure of that?+
This is an early study (Phase 1), focused mostly on safety. Every study is reviewed and monitored by an independent ethics board (called an IRB) whose job is to protect participants, and care is overseen by licensed medical staff. You'll be told the known risks before you agree to anything, and you can stop at any time.
Will I get a placebo instead of the real treatment?+
Some studies compare a treatment against a placebo (an inactive version), and some don't. If this one does, the study team will explain your chances of receiving the active treatment before you decide. Nothing is hidden from you.
Do I have to stop taking my current medications?+
It depends on the study. Some let you stay on your current medications and some ask you to adjust them. Never stop a medication on your own — the study team will review everything with you first.
Does it cost anything? Will I be paid?+
The study treatment and study-related visits are provided at no cost to you. Some studies also pay for your time; the coordinator can tell you if this one does. You should never be asked to pay to take part.
Do I need insurance? Will anyone ask about my immigration status?+
No. You do not need health insurance to take part in a research study, and you will not be asked about your immigration status to join. Taking part is about whether you're a medical fit for the study.
What if English isn't my first language?+
You have the right to understand everything before you agree. Study sites can often provide materials or an interpreter in your language — you can ask the coordinator for one.
Is my information private?+
Yes. Your health information is only shared with the study sites you choose to be contacted by, and only to help match and enroll you. It is never sold, and you can ask us to delete it at any time.
Some requirements (like specific lab values or timing) are confirmed directly by the study team, not by us.
