PTCs-based Precision Treatment Strategy on Recurrent High-grade Gliomas

February 9, 2025 updated by: Yang Zhang, Beijing Tiantan Hospital

Study on Precision Treatment Strategy Through PTCs (patient-derived Tumor-like Cell Clusters)-based Drug Screening for Recurrent High-grade Gliomas

This trial is an open-label, single-arm, phase 0/1 study of high-grade glioma that aims to evaluate the feasibility, preliminary efficacy and safety of the precision treatment strategy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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

The investigators have established a precision treatment strategy, that select chemotherapeutic drugs or targeted drugs based on information from PTCs drug-screening or/and bioinformatic prediction. In this study, the investigators are going to exploit this strategy for the precision treatment of recurrent high-grade gliomas. The investigators will evaluate the feasibility, safety and preliminary efficacy via collecting the indexes comprising clinical presentation, results of imaging examination, clinical assays, KPS, neurological score, etc.

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

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Receiving chemotherapeutic or targeted drugs recommended by molecular tumor board.
These drugs included all the FDA-approved drugs that have been used in treating gliomas. A single drug or a drug combination for a specific patient will be recommended by the molecular tumor board, comprising neurooncologists, neurosurgeons, pharmacologists, cancer biologists, radiologists and bioinformaticians, will recommend , based on their expertise, patients willingness as well as evidences from PTCs-drug screening and bioinformatic prediction for drug response.
Drug: Receiving chemotherapeutic or targeted drugs recommended by molecular tumor board.
Patients will be treated with FDA-approved chemotherapeutic or targeted drugs which were recommended by the molecular tumor board (MTB), based on their expertise, patients willingness as well as evidences from PTCs-drug screening and bioinformatic prediction for drug response.
