About this trial

Lipomas are benign tumors composed of mature adipose tissue. While harmless, these are the most common type of soft tissue growths with some patients developing numerous lipomas. Patients often seek removal for cosmesis, or symptoms caused by location and/or compression of surrounding structures. This exploratory study aims to evaluate the effectiveness of subcutaneous injections of cooled normal saline as a treatment option for lipomas. The study will assess whether this technique could serve as a viable alternative to existing treatment options, especially compared to topically applied fat-freezing devices. The Investigators propose that this method may offer a more comfortable nonsurgical option for targeted fat reduction, as the cold temperatures are applied directly to the lipomas.

Amendment to Protocol Feb 2026- Including and additional ARM of the study to evaluate the effectiveness of subcutaneous injections of warmed normal saline as a treatment option for lipomas.

Treatments tested in this trial

  • Cooled Sodium Chloride Injection

    Drug

    A 30-gauge, 0.5-inch needle attached to a 3 mL syringe will be used to directly inject the solution transcutaneously into the lipoma. Injection of a solution containing sterile, cooled 0.9% sodium chloride and 1% lidocaine with epinephrine (1:100,000).

  • Warmed Sodium Chloride Injection

    Drug

    A 30-gauge, 0.5-inch needle attached to a 3 mL syringe will be used to directly inject the solution transcutaneously into the lipoma. Injection of a solution containing sterile, warmed 0.9% sodium chloride and 1% lidocaine with epinephrine (1:100,000).

Trial outcomes

Primary outcomes

1

Post-Injection Pain (First Treatment)

Pain is assessed using a scale of 0-10 reported by the patient, with 0 being no pain and 10 being the worst pain ever experienced.

Time frame
15 minutes post injection (treatment)
2

Post-Injection Pain (Second Treatment)

Pain is assessed using a scale of 0-10 reported by the patient, with 0 being no pain and 10 being the worst pain ever experienced.

Time frame
15 minutes post injection (treatment)
3

Post-Injection Pain (Third Treatment)

Pain is assessed using a scale of 0-10 reported by the patient, with 0 being no pain and 10 being the worst pain ever experienced.

Time frame
15 minutes post injection (treatment)
4

Post-Injection Pain (Forth Treatment)

Pain is assessed using a scale of 0-10 reported by the patient, with 0 being no pain and 10 being the worst pain ever experienced.

Time frame
15 minutes post injection (treatment)
