In Vivo Real-time Detection of Circulating Melanoma Cells

Study Purpose

The objective of this clinical trial is to determine whether a Photoacoustic flow cytometry (PAFC)-based prototype device can detect circulating tumor cells (CTCs) in the blood of melanoma patients in vivo, in real time, and do so at detection limits at least one order of magnitude below the detection limits of currently existing ex vivo methods.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	Yes
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	18 Years - 80 Years
Gender	All

- Signed informed consent form approved by the University of Arkansas for Medical Sciences (UAMS) Institutional Review Board (IRB) - Must be able to sit still for 90 minutes.

Exclusion Criteria:

- Active infection.

- Current and significant medical or surgical condition as determined by the Investigator.

- Diagnosis or evidence of organic brain syndrome.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT01776905
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Study Population: Approximately 80 subjects will be consented in order to achieve an enrollment goal of 75 subjects at this institution in three cohorts as follows: 1. Cohort #1 will consist of fifteen healthy control subjects, ten of whom will be Caucasian and five of whom will be African-American. Subjects in cohort #1 will be used to address the calibration goal of Specific Aim #1. 2. Cohort #2 will consist of 30 subjects who have advanced-stage melanoma will be recruited from the Medical Oncology clinic at UAMS, where advanced stages are defined as Stages III or

IV. Subjects in cohort #2 will be used to address the validation goal of Specific Aim #2.

Approximately half of the 30 advanced-stage subjects will be Stage III and the other half will be Stage

IV. 3.

Cohort #3 will consist of 30 subjects with early-stage melanoma will be recruited from the Surgical Oncology clinic at UAMS, where early stages are defined as Stages I or

II. Subjects in cohort #3 will be used to address the detection goal of Specific Aim #3.

Approximately 10 of the 30 early-stage subjects will be Stage I and approximately 20 will be Stage II.

Arms & Interventions

Arms

: Healthy control subjects

Characterize the baseline PA signals produced by the in vivo PAFC prototype device in healthy volunteers or Develop Standard Curves for the ex vivo CTC assays.

: Advanced-Stage Melanoma

To validate the in vivo PAFC method of melanoma CTC detection, we will use the PAFC-based prototype device to noninvasively determine CTC concentrations in the blood of subjects who have advanced-stage (Stage III or Stage IV)melanoma, and we will also use current ex vivo methods to determine the CTC concentration in samples of blood drawn from the same subjects.

: Early-Stage Melanoma

To determine whether in vivo PAFC can detect melanoma CTCs at concentrations below the detection limits of the ex vivo methods, we will use the PAFC-based prototype device to noninvasively detect CTCs in the blood of subjects who have early-stage (Stages I or II) melanoma, and we will also use current ex vivo methods to detect CTCs in samples of blood drawn from the same subjects.
