Lattice radiation therapy for treating large tumors

A Phase 2 Study of Lattice Radiotherapy for Dose-Escalated Palliation of Bulky Tumors

Phase 2 Interventional University of Cincinnati · NCT06416007

This study is testing a new type of radiation therapy called lattice radiation therapy to see if it works better than standard treatment for people with large tumors.

What this trial studies

This clinical trial aims to evaluate the effectiveness of lattice radiation therapy (LRT) in providing better treatment outcomes for patients with bulky tumors compared to standard radiotherapy. It is a single-institution, single-arm Phase II trial that plans to enroll 37 patients, who will receive LRT in five fractions delivered every other day. The study will assess the overall response rate (ORR) at 60 days post-treatment and monitor safety and toxicity at various intervals. Additionally, a translational analysis will explore the impact of LRT on systemic immune responses.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with solid tumor malignancies that require radiation and have measurable disease.

Not a fit: Patients with hematologic malignancies or those receiving cytotoxic chemotherapy or radiosensitizing agents may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer improved outcomes for patients with large tumors that are difficult to manage with conventional therapies.

How similar studies have performed: While lattice therapy is a novel approach, similar studies have shown promise in enhancing treatment efficacy for bulky tumors.
