Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Sampling Method
Study Population
Aim 1: Dosimetry/ Safety Group Ten healthy adult volunteers (5 males and 5 females) will be recruited and undergo whole-body PET/CT imaging for assessing the safety, dosimetry and metabolism of [11C]-CS1P1.
Aim 2: Feasibility Cohort Aim 2A will consist of 24 adult volunteers that will be recruited and scanned to characterize [11C] CS1P1 uptake on PET scans of the brain and cervical lymph nodes, to assess for radiolabeled metabolites. Up to 20 participants who have completed Aim 2A will continue with the collection of test-retest and safety data, Aim 2B. Ten healthy controls age and gender-matched to 10 participants with MS will be invited to return for repeat imaging for test-retest reliability not less than 7 days after and not more than 12 months after baseline imaging.
Description
Inclusion Criteria:
- Male or female, any race;
- Age ≥ 18 years;
- Capable of providing written informed consent for volunteering to undergo research procedures.
- Healthy volunteer or volunteer with a diagnosis of MS
Exclusion Criteria:
- Hypersensitivity to [11C]-CS1P1 or any of its excipients;
- Contraindications to PET, CT or MRI (e.g. certain incompatible electronic medical devices, inability to lie still for extended periods) that make it potentially unsafe for the individual to participate;
- Severe claustrophobia
- Women who are currently pregnant or breast-feeding;
- Currently undergoing radiation therapy;
- Any condition that, in the opinion of the Sponsor-Investigator or designee could increase risk to the participant, limit the participant's ability to tolerate the research procedures or interfere with collection of the data (e.g., renal or liver failure, advanced cancer);
- Participants who in the last 6 months experienced any of the following cardiovascular conditions or findings in the screening electrocardiogram (ECG): unstable cardiac arrhythmias, myocardial infarction, unstable angina, stroke, transient ischemic attack or decompensated heart failure requiring hospitalization or Class III/IV heart failure;
- Must not have participated in any clinical trial involving a study drug or device within the 30-days prior to study enrollment;
- Must not participate in another drug or device study prior to the end of this study participation;
- Current or recent (within 12 months prior to screening) participation in research studies involving radioactive agents such that the total research-related radiation dose to the participant in any given year would exceed the limits set forth in the U.S. Code of Federal Regulations (CFR) Title 21 Section 361.1.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Experimental: [11C] CS1P1
|
Participants will receive a single intravenous bolus injection of 6.0 - 20.0 mCi (222-740 MBq) of the investigational radiotracer [11C] CS1P1.
Participants will then undergo a [11C] CS1P1 PET/CT scan.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The tracer [11C]-CS1P1 will be injected for the first time into humans, using a dose range of 12-17 mCi for evaluations of safety, biodistribution, and dosimetry.
Time Frame: 2 years
|
Whole-body PET/CT images (skull vertex to proximal thighs) will be obtained in 10 healthy volunteers (5 males and 5 females) for up to a maximum of 4 hours immediately following intravenous (IV) injection of 12-17 mCi of [11C]-CS1P1 (dosage range calculated from rodent dosimetry data extrapolated to humans).
|
2 years
|
PET imaging studies of [11C]-CS1P1 in healthy normal control participants and human participants with multiple sclerosis.
Time Frame: 2 years
|
We hypothesize that specific binding of [11C]-CS1P1 is elevated in participants with neuroinflammatory/neurodegenerative diseases of the CNS compared to healthy normal control participants.
