Varian ProBeam Proton Therapy System China Clinical Trial (Guangzhou)

Varian, a Siemens Healthineers Company47 enrolled

Overview

This study is prospective, single-center, single-arm objective performance criteria. This trial will be conducted with a total of 47 subjects enrolled. All of subjects will be treated with radiation therapy using the medical device Varian ProBeam Proton Therapy System (ProBeam), aim to compare the data with objective performance criteria (OPC) to evaluate the effectiveness and safety of ProBeam radiotherapy system for oncology patients, providing a clinical basis for the medical device registration.

Oncology patients, including tumors of head and neck, chest, abdomen, spine, pelvic cavity, extremities and other tumors. The screening period from informed consent to enrollment is expected to be 2 weeks, while the treatment period depends on patient medical situation and treatment plan. The period after the last treatment is divided into short-term follow-up which is 90 days after treatment completion and long-term follow-up which is 5 years after treatment completion. The clinical trial with short-term follow-up fulfills the requirements for National Medical Products Administration (NMPA) regulatory registration. All the end points claimed will be achieved in the short-term follow-up stage. The trial is defined as completion once short-term follow-up is finished. And long-term follow-up report will be submitted for future post market evaluation when requested by NMPA.

Outcomes

Primary Outcomes

Effectiveness evaluation: Local tumor control rate 90 days after the proton radiation treatment completion

At 90 days after the treatment completion, the number of cases in partial response (PR) and stable disease (SD) and complete response (CR) accounted for the proportion of total cases will be rated according to Response Evaluation Criteria in Solid Tumors RECIST Version 1.1 (RECIST 1.1) criteria.

Time frame: 90 days ± 7 days after treatment completion

Safety evaluation: Incidence of Acute radiation injury

Observe acute radiation injury occurrence throughout the trial period, including the treatment period and the 90-day follow-up period. Acute radiation injury will be summarized separately (calculating quantity of participants, number of cases, and incidence) based on Radiation Therapy Oncology Group (RTOG) Grading Criteria.

Time frame: from enrollment to 90 days ± 7 days after treatment completion

Safety evaluation: Incidence of Adverse Events based on CTCAE 5.0 criteria

Record Incidence of Adverse Events and estimate according to Common Terminology Criteria for Adverse Events version 5.0 (CTCAE 5.0) criteria, level 3 toxic reaction ratio should be lower than the acceptable value (5%), level 4 and 5 toxic reaction should not occur.

Time frame: from enrollment to 90 days ± 7 days after treatment completion
