Stereotactic Body Radiotherapy (SBRT) for Early Treatment of Oligometastatic Adenoid Cystic Carcinoma: The SOLAR Trial

Adenoid Cystic Carcinoma Clinical Trial

Official title: Stereotactic Body Radiotherapy (SBRT) for Early Treatment of Oligometastatic Adenoid Cystic Carcinoma: The SOLAR Trial

Status Recruiting

Clinical Trial Summary

The aim of this study is to learn whether the early initiation of a specialized and focused type of radiation called stereotactic body radiation therapy (SBRT) will impact the progression of advanced adenoid cystic carcinoma, quality of life, and overall survival.

The name(s) of the study intervention involved in this study is:

• Stereotactic Body Radiation Therapy (SBRT)

Clinical Trial Description

This is a randomized phase II, open-label and non-blinded two-arm study aimed to investigate the potential benefit of treating oligometastatic adenoid cystic carcinoma (ACC) with early initiation of stereotactic body radiotherapy (SBRT). Given the overall uncertainty about the role of local therapy in the treatment of ACC, there is also a prospective observational cohort that will investigate outcomes following local ablative treatments in patients with advanced or metastatic ACC.

This research study is investigating how the specialized and focused stereotactic body radiation therapy (SBRT) impacts disease progression, quality of life, and overall survival in patients with a limited number of metastases (one to five) from their adenoid cystic carcinoma cancer. The use of SBRT to treat all areas of disease after early spread of ACC is investigational. SBRT is a more focused form of radiation compared to the palliative radiation typically received per standard of care treatment. Recent retrospective studies conducted suggest that patients with adenoid cystic carcinoma cancer may benefit from early initiation of a targeted radiation therapy.

The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits. After enrollment participants will be randomized into two groups: Standard of Care or Stereotactic body radiotherapy (SBRT). All participants in the study, regardless of treatment regimen, will be followed for up to 10 years.

It is expected that about 66 people will take part in this research study.

Two organizations, Gateway for Cancer Research and the Adenoid Cystic Carcinoma Research Foundation (ACCRF), are supporting this research study by providing funding. ;
