A Taiwanese Oncogenetic Panel and Integrated Clinical Data Registry Study for Diffuse Glioma

Study Purpose

Glioma is a major histological subtype of primary malignant brain tumors in Taiwan, with distinct epidemiological, clinical, and pathological features comparing to the other common cancer diseases. The disease rarely appears with metastatic disease at diagnosis, and with the most malignant subtype, glioblastoma, occurs with preference in mid- to old-age. For decades, primary malignant brain tumors has been known as one of the most desperate disease without successful improvement regarding of the treatment. Surgical resection is the principle for the primary treatment of gliomas. Chemotherapy and radiotherapy are often applied to patients for adjuvant therapy of surgery to pursue the treatment effect. Disappointedly, vast majority of the patients would eventually develop disease recurrence, leaving only limited choice for salvage treatment thereafter. The prognosis of these patients remains desperate, and thus a better understanding of this deadly disease is crucial for finding better therapeutic strategies for these patients.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	Unknown
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	20 Years and Over

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Pathological confirmation or suggestion of adult-type diffuse gliomas A. Diagnosis includes glioblastoma, astrocytoma, oligodendrocytoma that is listed in ATDG category per WHO criteria. B. Gliomas that are preferred as ATDGs from pathological and clinical views, but not given for confirmed diagnosis. 2. Willingness to provide archival or newly obtained tumor tissues for current study proposal. 3. Age equal or more than 20 years old (inform consent). 4. Life expectancy more than 3 months. 5. Patients fully understand the protocol with the willingness to have regular follow-up. 6. Additional criteria for individual arms A. [Arm 1] Within 2 months after surgery for primary tumor. B. [Arm 2] Total resection of primary tumors with tissue samples available for test. C. [Arm 3]

(1) Total resection of primary tumors with the paired primary and recurrent tissue samples available for test.

(2) IDH test suggesting wild-type.

Exclusion Criteria:

1. Gliomas diagnosed or preferred as other categories than ATDGs, such as pediatric-type diffuse gliomas, circumscribed astrocytic gliomas, and others. 2. Inability to cooperate by providing a complete medical history. 3. Patients disagree to provide archived tumor samples. 4. Undesirable compliance. 5. Having a known additional malignancy that is progressing or has required active treatment within the past 3 years. Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ (e.g., cervical carcinoma in situ) that have undergone potentially curative therapy are not excluded.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05622409
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

With demand of molecular characterization in precise diagnosis, we proposed this registry study to explore the impact of the new criteria by applying next-generation sequencing. The specific aims of this project are

(1) to establish the tumor genetic and molecular profiles of adult-type diffuse gliomas in Taiwan, (2) to understand the treatment prognosis depending on difference of the genetic and molecular profiles for adult-type diffuse gliomas in Taiwan, and (3) to reveal the evolutionary changes of genetic and molecular features of adult-type diffuse gliomas.

The long-term goals of this study are to help implement personalized therapy, to develop novel therapy, and to improve outcomes of patients with adult-type diffuse gliomas. It is also expected to create a platform for data storage and sharing.

Arms & Interventions

Arms

: Arm 1

Newly diagnosis arm (N=150): The study aims to obtain clinical information to correlate with genetic characterization of ATDGs of all types. Only patients with primary tumors that have recently received surgery are applicable.

: Arm 2

Post treatment arm 1 for training set (IDH-wild type ATDGs, N=50; IDH-mutant ATDGs, N=50): The study aims to compare the genetic differences of ATDGs in terms of IDH mutation status. Samples of primary tumors are preferred but can be replaced with recurrent ones. Paired samples are both eligible for typing if the recurrent diseases of IDH-mutant tumors possess potential altered genes (such as up grading per histology features).

: Arm 3

Post treatment arm 2 (recurrent ATDGs; N=25): The study will focus on recurrent diseases of ATDGs to study the consistency of genetic difference of the primary and the recurrent tumors. Tumor free is mandatory and needs to be documented after resection of the primary tumor. Patients remain eligible if IDH statuses are uncertain.
