Trial summary

For patients of GIST (Gastrointestinal Stromal Tumor), Imatinib has been widely used in GIST with KIT or PDGFRA sensitive mutations. From clinical points of view, individual differences often occur between different patients, leading diverse effect in ADR and drug effect. Read more about this study

About this study

Official title: Retrospective Study Based on Pharmacokinetics, Somatic Mutations and Genetic Polymorphisms Related to Individual Variations of Drug Effect and Adverse Drug Reaction of Imatinib in Gastrointestinal Stromal Tumor Treatment.

For patients of GIST (Gastrointestinal Stromal Tumor), Imatinib has been widely used in GIST with KIT or PDGFRA sensitive mutations. From clinical points of view, individual differences often occur between different patients, leading diverse effect in ADR and drug effect. Meanwhile, the drug effect and adverse drug reaction was significantly influenced by the pharmacokinetic factors and pharmacodynamic and other factors. In this research, we try to establish a more sensitive method to detect sensitive mutations in plasma and discover the correlation between somatic and germline mutations, plasma trough concentration and drug effect, the association between ADME-associated SNP, Target/Receptor/Pathway-associated SNP, trough concentration and TKI adverse effect. Furthermore, in vivo and in vitro research is also crucial for rational explanation for these clinical phenomenon.

Read the detailed description

The plasma concentration of Imatinib were established. The ADME-associated SNPs included are CYP3A4, CYP3A4, CYP1A1, CYP2C9, CYP2C19, ABCB1, ABCG2, ABCC4, SLC22A1, SLCO1B3 and so on. The Target/Receptor/Pathway-associated SNP s included KIT, PDGFRA, PDGFRB, FLT1, FLT3, MAPK1, SHC1, CCL5, CXCL14 and so on. The somatic mutations included are KIT, PDGFRA, BRAF and so on.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT03092128
Study groupRoleWhat they receive
sensitive group; non-sensitive groupsensitive patients were defined as patients reached CR or PR after first month administration,SD after first three months administration. non-sensitive patients were defined as patients reached PD after first month administration and first three months administration.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression free survival

    Excluding clinical deterioration without evidence of objective progression according to the Response Evaluation Criteria In Solid Tumors (RECIST), or death from any cause.

    Measured: The time from the date of randomisation (baseline) to the date of objective tumour progression,and expected average of 36 months.

Secondary outcomes (1)
  1. Number of patients with objective response and adverse events

    Objective responses (complete response plus partial response) and disease control (objective response plus stable disease≥6 weeks) were established according to RECIST.And adverse events was established according to CTCAE.

    Measured: one month, three month, 12 month

Questions about this trial

What is this clinical trial studying?

An observational study of Gastrointestinal Stromal Tumors and Germline Mutation, run by Xueding Wang at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 13 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Wei Zhuang, Ph.D (86-13427526343, zhuangw@mail2.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression free survival (time frame: The time from the date of randomisation (baseline) to the date of objective tumour progression,and expected average of 36 months.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03092128, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Sep 2018.
