April 15, 2024 updated by: Stanford University
Biodistribution and Pharmacokinetic Study of the Positron Emission Tomography (PET) Radiopharmaceutical [18F]-C-SNAT4
Primary Objectives
- Determine the biodistribution of [18F]-C-SNAT4 in 5 healthy volunteers. Secondary Objectives
- Determine the dosimetry of [18F]-C-SNAT4 PET in healthy volunteers and patients with lung cancer.
- Determine the acute toxicity of [18F]-C-SNAT4 PET in healthy volunteers and patients with lung cancer.
- Determine whether uptake in [18F]-C-SNAT4 PET imaging is significantly different in tumor and corresponding contralateral noncancer tissue in patients with lung cancer (tested by Wilcoxon test) before the therapy.
- Determine/verify the safety profile of the [18F]-C-SNAT4 radiotracer, as an imaging agent in patients with lung cancer.
- Determine the time of maximal [18F]-C-SNAT4 radiotracer uptake post injection.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Healthy volunteers (Group 1)
Group 1(n = 5) healthy volunteers.
Each participant in this part of the study will receive a single dose of [18F]-C-SNAT4 and then undergo three times of whole body (WB) PET/CT scans (Scan 1: 60 minutes dynamic scan; Scan 2: WB skull base-thigh at 90 minutes +/- 10 minutes post injection; Scan 3: WB skull base-thigh at 120 minutes +/- 10 minutes post-injection of [18F]-C-SNAT4).

Radiotracer- Dose 10 mCi
Positron emission tomography (PET)/Computed tomography (CT) Scan
|
Experimental: Patients with newly diagnosed lung cancer (Group 2)
Group2 (n = 5) newly diagnosed lung cancer.
Each participant in this part of the study will receive a single dose of [18F]-C-SNAT4 and then undergo three times of whole body (WB) PET/CT scans (Scan 1: 60 minutes dynamic scan; Scan 2: WB skull base-thigh at 90 minutes +/- 10 minutes post injection; Scan 3: WB skull base-thigh at 120 minutes +/- 10 minutes post-injection of [18F]-C-SNAT4).

Positron emission tomography (PET)/Computed tomography (CT) Scan
|
Experimental: Patients with lung cancer undergoing non-surgical tx (Group 3)
Group 3 (n = 10) lung cancer after non-surgical therapy.
Each participant in this part of the study will receive a total of 2 doses of [18F]-C-SNAT4 (on 2 separate occasions spaced at least 1 week apart, each of which will be followed by undergoing a [18F]-C-SNAT4 PET/CT scan)

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Biodistribution of [18F]-C-SNAT4
Time Frame: 1 day
|
Whole-body [18F]-C-SNAT4 PET scans will be performed at 60 min post intravenous injection of the PET tracer in Group 1 of 5 healthy volunteers
|
1 day
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Dosimetry of [18F]-C-SNAT4
Time Frame: 1 day
|
Radiation dosimetry of the [18F]-C-SNAT4 radiotracer will be measured through careful monitoring of each participant's vital signs in Group 1 and group 2. Time-Activity curves will be graphed by measuring activity in various organs using multiple PET/CT scans (1 hour dynamic scan, 1 hour and 2 hours) after tracer injection.
Absorbed radiation will be calculated.
|
1 day
|
Toxicity of [18F]-C-SNAT4
Time Frame: 7 days
|
The acute [18F]-C-SNAT4 toxicity will be assessed as related adverse events, including laboratory abnormalities, that occur within 7 days of the infusion of [18F]-C-SNAT4.
|
7 days
|
18F]-C-SNAT4 Uptake
Time Frame: 1 day
|
The tumor uptake of [18F]-C-SNAT4 PET will be compared with the corresponding contralateral non-cancer tissue in patients with lung cancer before the therapy in Group 2 and 3. SUVmax measurements will be taken from the pre-treatment scan.
|
1 day
|
The Maximal [18F]-C-SNAT4 Uptake as PET Radiotracer
Time Frame: 1 day
|
The time of maximal [18F]-C-SNAT4 radiotracer uptake post-injection will be assessed in Group 2 and 3. Time-Activity Curves (TAC) will be graphed by measuring activity in tumor after tracer injection.
The maximal of [18F]-C-SNAT4 radiotracer uptake post-injection in lung cancer patients will be determined from these time activity curves.
|
1 day
|
[18F]-C-SNAT4 PET Imaging Signal in Responders and Non-responders
Time Frame: 7 days
|
The [18F]-C-SNAT4 PET scan signal from pre-therapy to one week after initiation of therapy in Group 3 will be compared both in treatment responders vs. non-responders.
SUVmax will be measured in both the pre-treatment and one-week post-initiation of treatment scans.
