Treatment of skin and soft tissue cancers using alpha radiation emitters

A Safety and Preliminary Effectiveness Study of Intratumoral Diffusing Alpha Radiation Emitters on Cutaneous, Mucosal and Superficial Soft Tissue Neoplasia

Not applicable Interventional Alpha Tau Medical LTD. · NCT03886181

This study is testing a new treatment that uses tiny radioactive seeds inserted into skin and soft tissue cancers to see if it can shrink tumors safely.

What this trial studies

This clinical trial evaluates the safety and efficacy of a novel treatment method using diffusing alpha radiation emitters (DaRT) for patients with superficial cutaneous, mucosal, or soft tissue neoplasia. The approach involves inserting radioactive seeds directly into the tumor, allowing for localized radiation therapy that aims to reduce tumor volume and increase necrotic tissue. The study will assess outcomes 30-45 days after the insertion and removal of the seeds, focusing on both tumor response and safety through monitoring adverse events. It is a prospective, open-label, single-arm controlled study.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with histopathologically confirmed superficial malignant tumors measuring 5 cm or less.

Not a fit: Patients with larger tumors, poor performance status, or specific histological types like Keratoacanthoma may not benefit from this treatment.

Why it matters

Potential benefit: If successful, this treatment could provide a targeted and effective option for patients with superficial skin and soft tissue cancers.

How similar studies have performed: While this approach is innovative, similar studies using localized radiation therapies have shown promise in treating superficial tumors.
