Metabolic Phenotypes in Melanoma

Get Involved

Study Purpose

This is a single centre, correlative, longitudinal, biomarker study that aims to describe the metabolic features of human melanoma using mass spectrometry.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
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.	Interventional
Eligible Ages	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Patient has provided written informed consent. 2. Male or female aged 18 years or older at written informed consent. 3. Presence of a known melanoma lesion requiring surgical excision or biopsy. 4. Patient is willing and able to comply with the protocol for the duration of the study including undergoing biopsies and receiving a stable isotope infusion (where applicable)

Exclusion Criteria:

Patients who meet any of the following criteria will be excluded from receiving a [U-13C]Glucose infusion: 1. Diabetes mellitus. 2. Pregnancy or breast feeding. 3. Patients unable to comply with study procedures and follow up in the opinion of the investigator

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.	NCT05570227
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.	N/A

Additional Details

This is a single-centre, correlative study designed to investigate metabolic phenotypes in a longitudinal cohort of patients with melanoma. This study will involve the collection of tissue at the time of surgical excision or biopsy. The key intervention, in a subset of patients, will be to perform peri-operative infusions of a stable isotope, [U13C]Glucose. Patients will be intravenously administered sterile, pyrogen-free 13C-glucose, delivered as an 8g bolus followed by infusion of 4g/hour for 2-3 hours. Blood samples will be obtained to monitor glucose and to analyse enrichment of labelled nutrients by gas-chromatography mass spectrometry (GC-MS). At the time of resection or biopsy, tumour samples will be divided and either immediately frozen in liquid nitrogen or processed to form patient-derived xenografts. Frozen tumour samples will be subsequently processed for: isotope enrichment by GC-MS; global metabolomics by liquid-chromatography mass spectrometry (LC-MS); and genomic analyses. Relevant clinical, histologic and genomic features will also be correlated with metabolic findings.

Arms & Interventions

Arms

Experimental: [U-13C]Glucose Infusion

A 13.3% solution of sterile, pyrogen-free [U-13C]glucose in sterile water will be infused intravenously rapidly over 10 minutes to a total dose of 8 grams (bolus dose). Then the infusion will change to a rate of 4 grams/ hour. The infusion will continue until the time of tumour excision or biopsy, planned 2-3 hours.

No Intervention: No [U-13C]Glucose Infusion

Blood and tissue samples to be collected for translational research studies, no other additional intervention.

Interventions

Other: - [U-13C]Glucose Infusion

Peri-operative infusion of [U-13C]glucose
