Prospective Multicenter Clinical Study of Neoadjuvant Imatinib Mesylate for Gastrointestinal Stromal Tumors (ZJGIST-01)

October 9, 2021 updated by: Yu jiren, First Affiliated Hospital of Zhejiang University
The R0 resection rate of gastrointestinal stromal tumor (GIST) with high recurrence risk was relatively low, and the relapse-free survival rate was relatively low, which needed to be further improved. A few retrospective analyses and a small sample of prospective studies have found that neoadjuvant therapy with imatinib mesylate can improve R0 resection rates. Whether neoadjuvant therapy prolongs long-term survival remains unclear. The primary objective of this study was to evaluate 5-year progression-free survival (PFS) for GIST patients with high recurrence risk after neoadjuvant treatment with imatinib mesylate.

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

14 years to 76 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Patients receive oral imatinib mesylate 400mg once daily for 3-12 months in the absence of disease progression or unacceptable toxicity. Within 1 week after completion of preoperative imatinib mesylate, patients with responding or stable disease undergo surgical resection. After complete resection, patients receive oral imatinib mesylate 400mg once daily for 36 months in the absence of disease progression or unacceptable toxicity, and are followed for 5 years.
