Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

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

Who may be able to join

  • Male or female patients ≥ 18 years of age -WHO performance status (PS) of 0-2 -Histologically confirmed diagnosis of GIST that is unresectable or metastatic -.Available tissue specimen: • Dose-escalation part: patients must have available archival tumor tissue which can be shipped during the course of the study. In the absence of archival tumor tissue, patients must agree to a fresh pre-treatment biopsy at screening. • Dose-expansion part: patients must have available archival tumor tissue which can be shipped during the course of the study and must agree to a fresh pre-treatment biopsy
  • Failed prior therapy with imatinib followed by sunitinib for the treatment of unresectable or metastatic GIST. Note the following specific criteria for the two parts of the trial: • Dose-escalation part: patients who failed prior therapy with imatinib and then have failed therapy with sunitinib. Treatment failure may be due to either disease progression on therapy (both imatinib and sunitinib) or intolerance to therapy (sunitinib) • Dose-escalation part patients may have had additional lines of therapy than imatinib and sunitinib dose-expansion part: patients must have documented disease progression on both imatinib and sunitinib. In addition, patients may have had no more than two lines of prior therapy (i.e. treatment with imatinib followed by treatment with sunitinib). • Note: Adjuvant imatinib will not count as a prior course of imatinib for the purposes of this criterion 6. Radiological (CT/MRI) confirmation of disease progression (RECIST criteria) during prior therapy with imatinib and sunitinib will be required for patients entering the Dose-expansion part

Who cannot join

  • -Previous treatment with PI3K inhibitors -Patient has active uncontrolled or symptomatic central nervous system (CNS) metastases Note: A patient with controlled and asymptomatic CNS metastases may participate in this trial. As such, the patient must have completed any prior treatment for CNS metastases > 28 days (including radiotherapy and/or surgery) prior to start of treatment in this study and should not be receiving chronic corticosteroid therapy for the CNS metastases -Severe and/or uncontrolled concurrent medical condition that, in the opinion of the investigator, could cause unacceptable safety risks or compromise compliance with the protocol (e.g. acute or chronic liver, pancreatic disease, severe renal disease considered unrelated to study disease, chronic pulmonary disease including dyspnea at rest from any cause) -Patients with diabetes mellitus requiring insulin treatment and/or with clinical signs or with FPG >120mg/dL / 6.7mmol/L, or history of documented steroid-induced diabetes mellitus -Patient who has not recovered to grade 1 or better from any adverse events related to previous imatinib and/or sunitinib therapy before screening procedures are initiated

About this study

Official title: A Dose-finding Phase Ib Multicenter Study of Imatinib in Combination With the Oral Phosphatidyl-inositol 3-kinase (PI3K) Inhibitor BYL719 in Patients With Gastrointestinal Stromal Tumor (GIST) Who Failed Prior Therapy With Imatinib and Sunitinib

The purpose of this study is to determine a maximum tolerated dose and/or recommended phase 2 dose of a combination of imatinib and BYL719 in the treatment of 3rd line GIST patients.

Conditions
3rd Line GIST
Being tested
ST571 + BYL719
Keywords
Imatinib mesylate, STI571, BYL719, GIST, 3rd line GIST

What participants receive

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

  • ST571 + BYL719Drug

    Evaluable patients must meet the minimum treatment and safety evaluation requirements of the study. Patients will be treated until they experience progression of disease, withdraw consent, or experience unacceptable toxicity. One study cycle equals 28 days.

Study groups in NCT01735968
Study groupRoleWhat they receive
STI571 (imatinib mesylate) and BYL719ExperimentalThe study will comprise of 2 parts. A dose escalation and a dose expansion part. All patients in the dose escalation part will have a pharmacokinetic (PK) run-in period of 7 days receiving imatinib monotherapy. Patients will receive increasing doses of BYL719 (200, 300, 400 mg) in combination with 400mg imatinib daily until maximum tolerated dose (MTD) and rapid phase 2 dose (RP2D) is determined. Approximately 35 patients will enter the expansion phase.

What is being measured

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

  1. Frequency of dose limiting toxicities (DLTs)

    Dose limiting toxicity (DLT) will be assessed using Common Terminology Criteria for Adverse Events (CTCAE) (v4.0.3), unless otherwise specified in the protocol.

    Measured: 28 days (1st cycle)

  2. Characteristics of dose limiting toxicities (DLTs)

    Dose limiting toxicity (DLT) will be assessed using Common Terminology Criteria for Adverse Events (CTCAE) (v4.0.3), unless otherwise specified in the protocol.

    Measured: 28 days (1st cycle)

Secondary outcomes (10)
  1. Frequency and characteristics of DLTs

    Dose limiting toxicity (DLT) will be assessed using CTCAE (v4.0.3), unless otherwise specified in the protocol.

    Measured: 28 days (1st cycle)

  2. Imatinib and BYL719 plasma concentrations vs time profile

    Measured: 28 days (1st cycle)

  3. Clinical benefit rate (CBR)

    Clinical benefit rate is defined as the rate of confirmed complete response (CR) or partial response (PR), or stable disease (SD) which lasts for at least 16 weeks.Tumor response will be determined locally by the investigator sites according to Novartis guideline on the Response Evaluation Criteria in Solid Tumors, based on RECIST Version 1.1.

    Measured: 28 days (1st cycle)

  4. Type of adverse drug reactions

    Measured: 28 days (1st cycle)

  5. Frequency of adverse drug reactions

    Measured: 28 days (1st cycle)

  6. Severity of adverse drug reactions

    Measured: 28 days (1st cycle)

  7. Effect of basic Pharmacokinetics (PK) parameter: AUC0-24

    Measured: 28 days (1st cycle)

  8. Effect of basic PK parameter: Cmax

    Measured: 28 days (1st cycle)

  9. Effect of basic PK parameter: Tmax

    Measured: 28 days (1st cycle)

  10. Effect of basic PK parameter: CL/F

    Measured: 28 days (1st cycle)

A Phase 1 study testing ST571 + BYL719 in people with 3rd Line GIST, run by Novartis Pharmaceuticals at 11 sites in 8 countries.

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 2 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: finished, as of the sponsor's last update on 21 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Germany, Italy, Netherlands, United States, Belgium and 3 more countries. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Frequency of dose limiting toxicities (DLTs) (time frame: 28 days (1st cycle)). The study lists 2 primary outcomes in all. 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 NCT01735968, 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 21 Dec 2020.
