Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this research project is to assess the feasibility and safety of carbon-ion radiotherapy (CIRT) for the treatment of in Chinese localized prostate cancer

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to determine the maximal tolerated dose (MTD) of CIRT in the treatment of localized prostate cancer and to evaluate the efficacy of such treatment at the MTD. Participants will be treated with CIRT with escalating dose regimens to evaluate the maximal tolerated dose (MTD) in terms of acute and subacute toxicity observed during and within 6 months after the completion of CIRT. Once the MTD for localized prostate cancer is determined, the MTD will be used as the recommended dose to patients fulfilling the inclusion criteria in the Phase II part of the trial.

carbon-ion radiotherapy

Five dose levels \[59.2 GyE(Gray equivalent)/16Fx, 60.8 GyE/16Fx, 62.4 GyE/16Fx, 64.0 GyE/16Fx and 65.6 GyE/16Fx\] are planned within the Phase I part. After the recommended dose (RD), i.e., MTD, is determined or if the treatments to 65.6 GyE/16Fx are safely delivered, the recommended dose (or 65.6 GyE/16Fx) will be the prescribed dose in the Phase II part of the study.
