  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Ability to understand the risks of the study and to provide signed and dated informed consent and authorization to use protected health information (in accordance with national and local subject privacy regulations).
  • Age 18 years or older.
  • Unresectable and/or metastatic malignant GIST with objective progression of disease following treatment with a maximum of 3 tyrosine kinase inhibitors (TKIs) including imatinib.

  • Willing to provide a tissue block or unstained slides of archived tumour for central pathology review and genotyping, or a full pathology report and results of genotyping of a previous tumour sample, or willing to undergo a new tumour biopsy for central pathology review and genotyping during the screening period of the study (prior to dosing)

Who cannot join

  • Pregnancy or lactation (women of childbearing potential must have a negative serum or urine pregnancy test within 7 days prior to commencing treatment ). Male and female patients of childbearing potential must use appropriate birth control (abstinence, barrier methods, oral contraceptives and/or intrauterine devices) during the entire duration of the study, or the patient must be surgically sterile (with documentation in the patient's medical records).
  • Impaired liver function, as evidenced by prior liver segmentectomy or hemi-hepatectomy; or alanine or aspartate aminotransferase (ALAT/ASAT) >2.5x ULN; or alkaline phosphatase >2.0x ULN; or bilirubin >2.0x ULN.
  • Abnormal clotting, as evidenced by PT or PTT >1.5x ULN, or therapeutic/prophylactic anticoagulation.
  • Renal impairment, defined as either serum creatinine higher than the institution ULN,or estimated creatinine clearance lower than LLN (i.e. patients should have both normal serum creatinine, and normal estimated creatinine clearance)
  • Impaired marrow function, defined as haemoglobin <9.0 g/dL, neutrophils <1.5 x10^9/L, or platelets <100 x10^9/L. Patients may receive a blood transfusion for anaemia to allow entry to the study but should not be transfusion-dependent.
  • Left ventricular ejection fraction <50% on echocardiography or MUGA scan.
Show all 19Show fewer
  • Known metastases of the central nervous system.
  • Prior anticancer therapies including tyrosine kinase inhibitors (other than imatinib) not completed within 2 weeks or 5 half-lives of the agent (including known active metabolites) prior to treatment with study drug. Patients receiving imatinib should continue to receive imatinib (400 mg daily) throughout the screening period.
  • Clinically important intolerance or safety concerns with prior use of imatinib 400 mg daily.
  • Prior treatment with an HSP90 inhibitor.
  • Major surgery within 14 days prior to treatment with study drug, or failure to recover from the effects of such surgery.
  • Wide field radiotherapy within 4 weeks prior to treatment with study drug, limited field radiation within 2 weeks, or failure to recover from such therapies.
  • History of an ischaemic cardiac event or unstable cardiac disease within 3 months of study entry.
  • QTc >450 ms using Fredericia's correction.
  • Previous malignancy, except for basal cell and squamous cell skin carcinomas or carcinoma of the uterine cervix, unless treated with curative intent more than 2 years prior to study entry.
  • Evidence of severe or uncontrolled systemic medical conditions which make it undesirable for the patient to take part in the study, or which could jeopardize protocol compliance. Patients with multiple comorbidities and/or requiring multiple concomitant medications (especially conditions/medications which may impair renal function or predispose to renal impairment) should be discussed with the Astex Medical Monitor at the discretion of the Investigator before enrollment.
  • Prior history of infection with HIV, or known active hepatitis B or C viral infection (active screening for viral infections is not required for study entry).
  • Significant visual impairment such that in the opinion of the investigator, further minor deterioration would have unacceptable consequences (eg. loss of ability to drive or live at home.
  • The Safety Monitoring Committee may add other specific exclusion criteria to enhance the safety of the patients based on emerging safety data.

About this study

Official title: An Open-Label, Randomised, Multi-Centre, Phase II Study to Investigate the Safety and Efficacy of AT13387, Either as Monotherapy or in Combination With Imatinib, in Patients With Unresectable and/or Metastatic Malignant GIST Whose Tumour Has Progressed Following Treatment With a Maximum of Three Tyrosine Kinase Inhibitors

The purpose of this study is to investigate if an investigational drug called AT13387 is active against Gastrointestinal Stromal Tumor (GIST) that is resistant to other treatments, and to understand more about the safety of AT13387.

Most subjects in the study will receive AT13387 along with another drug called imatinib (Gleevec). Imatinib is a standard (approved) drug for treating patients with GIST. Some patients may receive AT13387 on its own. As a result, we shall begin to understand the effects of AT13387 given on its own and when combined with imatinib.We shall also find out more about the side-effects of AT13387, and more about how the body breaks down (metabolizes) AT13387.

Read the detailed description

The study consists of 3 parts: Part 1 is a dose escalation phase, Part 2 is a dose expansion phase and Part 3 is either a further dose expansion phase or a randomised phase in which half the patients receive AT13387 monotherapy and half continue to receive AT13387 in combination with imatinib.

All patients will receive AT13387 given by intravenous infusion on Days 1, 8, and 15 of a 28-day cycle. Most patients will also receive imatinib 400 mg by mouth every day.

Patients will have tumour imaging at baseline, and at 2, 4 and 6 months, and then at 2 month intervals until cycle 12, and then 3-monthly thereafter.

Blood samples will be taken to measure plasma drug levels of AT13387 given in combination with imatinib

What participants receive

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

  • AT13387 and ImatinibDrug

    Also called Gleevec

    In part 1 pts will receive AT13387 in combination with imatinib. Up to 5 possible dose levels of AT13387 could be evaluated in combination with imatinib 400 mg daily: 120 mg/m2, 150 mg/m2, 180 mg/m2, 220 mg/m2 and 260 mg/m2. AT13387 IV (in the vein) on day 1, 8 and 15 of each 28 day cycle, until progression or unacceptable toxicity develops, in order to establish the recommended phase II combination dose, which will be used in part 2 and/or part 3 of the study.

    In part 2 an additional 6-9pts will be treated.

    In part 3, provided that sufficient evidence of anti-tumour effect was observed in part 2 (disease stabilisation or reduction in tumour dimensions by RECIST), then an additional 12pts will be treated with AT13387 in combination with imatinib. Alternatively, if combination treatment is found to have excellent efficacy the randomised phase of the study may start so that 12 pts receive AT13387 on its own (monotherapy) and 12 pts receive AT13387 in combination with imatinib.

A Phase 2 study testing AT13387 and Imatinib in people with Gastrointestinal Stromal Tumor (GIST), run by Astex Pharmaceuticals, Inc. at 8 sites in United States.

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 7 inclusion and 19 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: finished, as of the sponsor's last update on 2 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of reduction/stabilisation of tumour size at 4 months according to Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 criteria (time frame: 4 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 NCT01294202, which also lists 1 linked publication.

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 2 Aug 2024.
