Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
SABR (stereotactic ablative body radiosurgery) treatment . SABR will be delivered as a single fraction of 20 Gy to 1-2 metastases (bone and/or lymph node) with the location of sites selected at the discretion of the treating radiation oncologist. This will be followed by Avelumab commencing within 5 days +/- 3 days of SABR. Avelumab will be administered at 10 mg/kg intravenous (IV) every 2 weeks (Q2W). A second course of treatment with SABR to 1-2 different metastases will be delivered 5 days +/-3 days after cycle 1 of Avelumab. The length of an Avelumab cycle is 14 days. All radiotherapy courses should be completed in a single session. The sites treated with radiotherapy should ideally be inclusive of both a bone and a lymph node metastasis.

Summary
Brief summary
The purpose of this study is to investigate the safety and efficacy of stereotactic ablative body radiotherapy (SABR) plus Avelumab in patients with metastatic castration-resistant prostate cancer (mCRPC).

Who is it for?
You may be eligible for this study if you are an adult with metastatic castration-resistant prostate cancer (mCRPC) and have a predicted life expectancy of at least 6 months.

Study details
This project will investigate the combination of SABR and Avelumab for metastatic castration resistant prostate cancer (mCRPC). SABR is a noninvasive, high precision radiotherapy technique. The high precision of SABR allows a high dose of
radiation to be delivered to the target areas with minimal toxicity to the surrounding areas.
Avelumab is a monoclonal antibody that works against a protein called PD1 on the surface of the cancer cells. It is thought that cancer cells with increased levels of PD1
avoid detection by the body’s immune system. In this study, we hypothesise that combining Avelumab with standard therapy high dose precision radiotherapy (SABR) may
enhance the antitumour efficacy of Avelumab in mCRPC. This study will evaluate the patient survival, tumour regrowth and side effects with this combined treatment in patients with mCRPC.
