About this study

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.

  • The target lesion is a measurable solid tumor, and the longest diameter of the lesion should be ≥10mm;
  • Those who have an expected survival time of more than 6 months;
  • Eastern Cooperative Oncology Group (ECOG) physical status is graded as 0~2;
  • Females of childbearing potential with a negative blood or urine pregnancy test result within 7 days prior to the first treatment;

Exclusion criteria

(Major Criteria):

  • There are contraindications to radiation therapy, including congenital susceptibility to ionizing radiation hypersensitivity; or the presence of comorbidity that may lead to ionizing radiation hypersensitivity, which will increase the sensitivity of normal tissues to radiation therapy;
  • The tumor recurring at the same site has received two or more radiotherapy treatments;

Treatment and study plan

Proton Radiation Therapy System (ProBeam)

Device

All enrolled subjects will be treated with Proton radiation therapy using the medical device Varian Proton Therapy System (ProBeam). 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 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.

Primary outcomes

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

    Time frame: 90 days ± 7 days after 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.

  2. Safety evaluation: Incidence of Acute radiation injury

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

    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.

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

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

    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.
