Assessing the safety of pentoxifylline and SABR for lung cancer treatment

Effect of Pentoxifylline and Vitamin E in Preventing Radiation-induced Toxicity in the Treatment of Recurrent or New Primary NSCLC Using Stereotactic Ablative Radiotherapy in Patients Previously Treated With Thoracic Radiation

Phase 2 Interventional University of Louisville · NCT01871454

This study is testing if combining a medication called pentoxifylline with a type of targeted radiation therapy can help people with recurrent lung cancer feel better and live longer.

What this trial studies

This phase II clinical trial aims to evaluate the safety and effectiveness of combining pentoxifylline with stereotactic ablative radiotherapy (SABR) in patients with recurrent or new non-small cell lung cancers. Participants will undergo imaging and pulmonary function tests to confirm eligibility before receiving the treatment. The study focuses on patients who have previously been treated for thoracic malignancies and are experiencing loco-regional recurrence. The goal is to determine if this combination therapy can improve outcomes for these patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a history of thoracic malignancy and a new or recurrent lung cancer within the previously irradiated area.

Not a fit: Patients with lung cancers that are not recurrent or new within the previously treated area may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new option for patients with recurrent lung cancers, potentially improving their prognosis.

How similar studies have performed: While this approach is being explored in this trial, similar studies have shown promise in combining radiotherapy with adjunctive therapies for cancer treatment.
