Study Summary

"This trial will study 20 patients with soft tissue sarcomas undergoing surgery. Patients will take 5-ALA before surgery to help identify tumor margins using fluorescence."

Who is the study for?
This trial is for patients with Grade 2 or 3 soft tissue sarcomas, who are scheduled for surgical removal of their tumor. Participants must be able to take the study drug orally before surgery.Check my eligibility
What is being tested?
The trial tests if a drug called Aminolevulinic Acid (5-ALA), taken orally, helps surgeons see cancerous tissues better during surgery. The goal is to improve the precision of tumor removal in soft tissue sarcoma patients.See study design
What are the potential side effects?
Potential side effects from Aminolevulinic Acid may include sensitivity to light, nausea, vomiting, liver enzyme changes, and skin reactions. These are based on known responses to similar procedures.

Experimental Treatment
Group I: Aminolevulinic acid (5-ALA)Experimental Treatment1 Intervention
20 mg/kg body weight of 5-ALA orally at 3-4 hours prior to surgical resection. 5-ALA fluorescence will be used to evaluate the resected tumor per gross margins and identifying further areas of fluorescing tissues beyond the gross tumor margins.

The trial's initial posting was on March 1st, 2024, with the latest update made on February 2nd, 2024. Although this particular study is not actively seeking participants, there are numerous other trials - a total of 439 - that are open for enrollment at present."

Answered by AI

Has the Food and Drug Administration endorsed Aminolevulinic acid (5-ALA) for medical use?

"Given that this is a Phase 1 trial with minimal safety and efficacy data, our team at Power rates the safety of Aminolevulinic acid (5-ALA) as 1 on a scale of 3."
