Pinoxin for the Prevention of Radiation-Induced Skin Injury

April 15, 2026 updated by: Zhen Zhang, Fudan University

A Multicenter, Randomized, Controlled, Double-Blind Clinical Study of Hydrogen-Donor Modified SOD (Pinoxin) for the Prevention of Radiation-Induced Skin Injury

The incidence of radiation-induced skin injury is high, and effective preventive measures are currently lacking. This study evaluates the role of the skin protective agent Pinoxin in preventing skin injury. Patients are randomly assigned into two prospective groups: treatment group and control group. In treatment group, patients will receive Pinoxin treatment. In control group，patients will receive placebo treatment. The rate of grade 2 or greater skin injury will be analyzed.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a prospective, randomized controlled, multicenter phase II study, with a design of superior efficacy，to compare the efficacy of Pinoxin and placebo in protecting radiation induced skin injury. We will consecutively enrolled patients who were diagnosed with cancer，and will receive radiotherapy at the dose of 50Gy or higher and radiation field is near skin. A total of 202 patients will be Randomized 1:1 to the treatment group and control group. In treatment group, patients will be sprayed Pinoxin，four times daily (morning, noon, evening, bedtime) from radiotherapy start until 2 weeks post-radiotherapy (continuous, including weekends) .In control group, patiants will received vitamin B12 as placebo. The dosing frequency is the same as that in the treatment group. Unblinding will be triggered if Grade 3 or higher reactions occur. If participants in the placebo control group develop Grade 3 or higher skin injury, they are permitted to use Pinoxin or opt for other appropriate symptomatic treatments.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Age ≥ 18 years, regardless of gender.
  2. Pathologically diagnosed with a malignant tumor.
  3. Scheduled to receive long-course radiotherapy with a total dose of ≥50 Gy, in accordance with standard treatment guidelines.
  4. No prior history of radiotherapy.
  5. Has provided signed and dated informed consent, indicating that the patient has been informed of all relevant aspects of the study.
  6. Patients who are willing and able to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures.

Exclusion Criteria:

  1. History of dermatologic conditions (e.g., vitiligo, psoriasis, etc.) or collagen vascular diseases.
  2. Planned hypofractionated radiotherapy regimen.
  3. Recent use (e.g., within 3 months) of similar topical protective agents.
  4. Known hypersensitivity to any related components or materials.
  5. Immunodeficiency disorders.
  6. Women who are pregnant or lactating.
  7. Any other condition that, in the investigator's judgment, may compromise patient safety or protocol compliance. This includes severe concomitant illnesses (including psychiatric disorders) requiring active treatment, significant laboratory abnormalities, or significant social/familial factors.
