  5. Number of Participants With Objective Response

    Objective response in participants was defined as the number of participants with confirmed complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Confirmed response were those that persisted on repeat imaging study for at least 4 weeks after initial documentation of response. CR was defined as disappearance of all lesions (target and non-target). PR was defined as at least 30 percentage (%) decrease in the sum of the longest dimensions of target lesions taking as a reference the baseline sum longest dimensions, with non-target lesions not increased or absent.

    Duration of response was defined as time (in months) from the first documentation of objective tumor response (confirmed CR or PR) to the first documentation of disease progression or death due to any cause. Confirmed response were those that persisted on repeat imaging study for at least 4 weeks after initial documentation of response. CR was defined as disappearance of all lesions (target and non-target). PR was defined as at least 30% decrease in the sum of the longest dimensions of target lesions taking as a reference the baseline sum longest dimensions, with non-target lesions not increased or absent. Progression was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study).

  9. Number of Participants With Adverse Events Based on National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) for Pharmacokinetic (PK) Subgroups

As per NCI CTCAE version 4.0, Grade1= asymptomatic or mild symptoms, Grade 2= Moderate;local or noninvasive intervention indicated; Grade 3 events =medically significant but not immediately life-threatening, unacceptable or intolerable events, significantly interrupting usual daily activity, require systemic drug therapy/other treatment, Grade 4 events =participant to be in imminent danger of death. Grade 5 events =death. Participants with any of the Grade 1 to Grade 5 AEs were reported. The PK evaluable participants were divided into 2 PK subgroups on Day 28 of Cycle 1: those with total drug (sunitinib + SU012662) trough plasma concentration (Ctrough) value less than (<) the median Ctrough value(lower exposure) and those with total drug (sunitinib + SU012662) Ctrough values greater than or equal to (>=) the median Ctrough value(higher exposure).

CR: disappearance of all lesions (target and non-target). PD:at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing sunitinib malate dose escalation and sunitinib malate in people with Gastrointestinal Stromal Tumors, run by Pfizer at 9 sites in 3 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 3 inclusion and 3 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 27 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Czechia, France. 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?

Yes. Results are posted in the registry (first posted 12 Mar 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Estimated Steady-State Maximum Plasma Concentration (Cmax,ss) of Sunitinib and Its Metabolite (time frame: pre-dose on Day 1, Day 12-18 and Day 25-29 of Cycle 1,2, 3 and 2, 4, 6, 8 hours post-dose on Day 1 Cycle 1). The study lists 6 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 NCT01396148, which also lists 2 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 27 Mar 2019.
