Lipoma

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.

This study aims to evaluate the safety, efficacy, and pharmacokinetics of Ronkyla Plus, a combinational drug that forms a hydrogel at the injection site, promising a better experience of lipolysis injection for the treatment of superficial lipoma. The study consists of a Part I dose-escalation study to investigate the drug's maximum tolerated dose (MTD) for this indication and a Part II study for evaluating its relative bioavailability in comparison to an FDA-approved lipolysis injection, Kybella.

Lipomas are non-cancerous growths of fatty tissue that develop under the skin in approximately 1 in 1000 people, though this number may be higher. While rarely symptomatic, they often cause emotional distress due to the unappealing appearance of the mass. Treatment of unsightly lipomas is excision with local anesthetic in the office or with sedation in the operating room. The recovery period is short and the procedure is low risk; however, the result of the operation is a visible scar over the site of the lipoma. Many patients defer surgical excision because excision of a lipoma is a cosmetic procedure, but the aesthetic outcome is undesirable. Radiofrequency ablation (RFA) is a technique that applies heat generated by a high frequency, alternating current to soft tissue. The hyperthermia produced by the current causes tissue necrosis that ablates the tissue into which the energy is directed. RFA has been successfully applied to thyroid nodules, pancreatic lesions, esophageal dysplasia and liver tumors. However, the manufacturers of the RFA technology have been focused on its application in pre-malignant and malignant lesions and have not yet considered its application to benign tumors. This study will test the success of RFA for superficial lipomas as a non-surgical option for treatment.

Lipoma is a relatively common, slow-growing mesenchymal neoplasm originating from adipose tissue. Patients seek treatment for lipomas for various reasons, such as concerns about their growth and spread, aesthetic issues, or worries about the compressive effects of the lipoma. Lipomas are typically removed surgically through excision, which can have complications including bleeding, infection, scarring, and recurrence. Other mentioned treatment methods include liposuction, laser, and medicinal approaches. Purified synthetic deoxycholic acid has been introduced as the first pharmacological intervention approved by the FDA for the reduction of submental fat. Deoxycholic acid is a type of bile acid that, due to its ability to cause non-selective cell lysis and disruption of adipocyte membranes (adipocytolysis), leads to emulsification of fat in the intestine. This is an interventional (pre-post), single-arm, and open-label study to evaluate the efficacy and safety of Embella (Deoxycholic acid, produced by Espad Pharmed Co.) for the management of superficial lipomas.
