The Therapeutic Effect of Thalidomide in RI

November 21, 2019 updated by: Yamei Tang, Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

The Effect of Thalidomide in Radiation-induced Brain Injury（RI）: a Phase II Clinical Trial

Purpose: This phase II clinical trial aims to evaluate the indications, therapeutic effects and side effects of thalidomide in radiation-induced brain injury.

Further study details as provided by Sun Yat-sen Memorial Hospital, Sun Yat-sen University / Yameitang.

Primary outcome measure: The primary endpoint is the brain injury remission at week 15. In brief, the brain lesion will be evaluated by using brain MRI scan before and after thalidomide regimen. The clinical efficacy is defined as ≥ 25% reduction in brain edema volume on FLAIR images at week 15, as compared with that before thalidomide usage.

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

There is no acknowledged and effective standard treatment for radiation-induced brain injury (RI). Glucocorticoids and bevacizumab during acute period are optional ways to reduce the brain edema. However, glucocorticoids and bevacizumab are unsuitable or ineffective for some patients, especially in the early stage of RI. The investigators supposed that angiogenesis might play a key role in the pathogenesis of RI, and that thalidomide, as an antiangiogenic drug, would reduce immature angiogenesis and improve vessel maturation in RI.

Primary objectives: This phase II clinical trial aims to evaluate the indications, therapeutic effects and safety of thalidomide in radiation-induced brain injury.

OUTLINE: This is a phase II, open-label, single arm clinical trial. Patients are enrolled and administrated with thalidomide. Thalidomide is supplied as 25 mg per pill to be taken by mouth.

Arm І: Patients receive thalidomide with a dosage of 25 mg at bedtime daily one week (days 1-7), then 50 mg at bedtime daily for one week (days 8-14), then 75 mg at bedtime daily for one week (days 15-21), then 100 mg at bedtime daily for 12 weeks (days 22-105), in the absence of unacceptable toxicity or severe deterioration.

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

35 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
