EMLA Topical Cream for Treatment of Pain in Patients Receiving Intra-Dermal Technetium 99 Injections for Lymphoscintigraphy for Skin Cancers

Study Purpose

This phase II trial tests how well EMLA topical cream works in treating pain in patients with skin cancers receiving Technetium 99 injections for a lymphoscintigraphy mapping procedure. A lymphoscintigraphy mapping procedure is used to find the main or lead lymph node (tissue that fight infection) so it can be removed and checked for tumor cells. Using lymphoscintigraphy to highlight and then surgically remove lymph nodes is standard way to treat skin cancer for many patients. The Technetium 99 injections used for lymphoscintigraphy can be briefly painful due to the sensitivity of the nerve endings in the skin. The EMLA topical cream, which contains a numbing medicine to block pain from nerve endings, has been studied in breast cancer patients with a difference in pain reported, but this is the first time it has been studied in patients undergoing lymphoscintigraphy for skin cancer. This study may help researchers learn whether the use of EMLA cream may improve the associated pain at the time of the lymphoscintigraphy procedure.

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.

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.

NCT06223659
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

PRIMARY OBJECTIVE:

  • I. Evaluate if the application of eutectic mixture of local anesthetics (EMLA) topical cream (2.5% lidocaine mixed with 2.5% prilocaine) prior to intra-dermal Technetium 99 sulfur colloid (Tc99 injection) for lymphoscintigraphy can improve associated pain.
OUTLINE: Patients are randomized to 1 of 2 cohorts. COHORT 1: Patients apply EMLA cream topically to skin 30 minutes prior to Tc99 lymphoscintigraphy procedure. COHORT 2: Patients apply placebo cream topically to skin 30 minutes prior to Tc99 lymphoscintigraphy procedure.
