About this study

Official title: Pharmacodynamic Study Using FLT-PET/CT in Patients With Advanced Solid Malignancies Treated With a Sequential Combination of X-82 and Docetaxel

This partially randomized phase I trial studies the side effects and how well sequential dosing of vascular endothelial growth factor receptor (VEGFR)/platelet derived growth factor receptor (PDGFR) dual kinase inhibitor X-82 and docetaxel works in treating patients with solid tumors. VEGFR/PDGFR dual kinase inhibitor X-82 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving VEGFR/PDGFR dual kinase inhibitor X-82 and docetaxel one at a time instead of concurrently may work in treating patients with solid tumors.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To evaluate the safety and tolerability of intermittent X-82 (VEGFR/PDGFR dual kinase inhibitor X-82) when administered in a 2 week on, 1 week off schedule (Cycle #1).

II. To evaluate the safety and tolerability of intermittent X-82 administered in combination with docetaxel every 3 weeks (Cycle #2).

III. To determine the change in vascular parameters using 3'Deoxy-3'-fluorothymidine (FLT) positron emission tomography (PET)/computed tomography (CT) to X-82 alone (Cycle #1).

IV. To determine the change in vascular parameters using FLT PET/CT to X-82 in combination with docetaxel (Cycle #2).

SECONDARY OBJECTIVES:

  1. To determine the objective response using Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 of intermittent X-82 with docetaxel.

II. To measure the change in plasma vascular endothelial growth factor (VEGF) levels with changes on FLT PET/CT.

III. To measure changes in X-82 pharmacokinetics with changes on FLT PET/CT.

TERTIARY OBJECTIVES:

  1. To evaluate the safety and tolerability of sequential X-82 with docetaxel in disease sub-populations. (Dose expansion cohort) II. To evaluate the objective response rate of sequential X-82 with docetaxel in these disease sub-populations. (Dose expansion cohort)

OUTLINE: Patients are randomized to 1of 2 treatment arms.

ARM I: Patients receive high dose VEGFR/PDGFR dual kinase inhibitor X-82 orally (PO) once daily (QD) on days 2-15. Beginning course 2, patients also receive docetaxel intravenously (IV) over 60 minutes on day 1.

ARM II: Patients receive low dose VEGFR/PDGFR dual kinase inhibitor X-82 PO QD on days 2-15 and docetaxel IV as in Arm I.

In both arms, courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

EXPANSION COHORT: Patients receive VEGFR/PDGFR dual kinase inhibitor X-82 as in Arm I and docetaxel IV over 60 minutes on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

What is being measured

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

  1. Incidence of toxicity graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.0 (Pharmacodynamic study)

    The number and severity of toxicities and adverse events will be summarized using frequencies and percentages and stratified by X-82 dose level (low or high) and treatment (X-82 alone or X-82/docetaxel). Ninety-five percent confidence intervals for the toxicity rates will be constructed.

    Measured: Up to 2 years

  2. Changes in the FLT PET/CT vascular parameters for VEGF/PDGF dual kinase inhibitor X-82

    The changes in FLT PET/CT parameters will be calculated and summarized using descriptive statistics and compared using a paired t-test or non-parametric Wilcoxon signed rank test.

    Measured: Baseline to day 15 (course 1)

  3. Changes in the FLT PET/CT vascular parameters for the combination of VEGFR/PDGFR dual kinase inhibitor X-82 and docetaxel

    The changes in FLT PET/CT parameters will be calculated and summarized using descriptive statistics and compared using a paired t-test or non-parametric Wilcoxon signed rank test.

    Measured: Day 1 to day 15 (course 2)

Secondary outcomes (3)

  1. Disease response assessed by the RECIST 1.1

    All patients with measurable disease will be classified as having either progressive disease (PD), stable disease (SD), a partial response (PR), or a complete response (CR). Responses will be summarized in tabular format delineating complete and partial responses as well as stable and progressive disease. A ninety-five percent confidence interval for the RECIST response rate will be constructed for the X-82 (low and high dose)/docetaxel combination.

    Measured: Up to 2 years

  2. Changes in VEGF

    Changes in VEGF levels will be summarized using descriptive statistics. Pearson's or Spearman's rank correlation analysis will be used to correlate changes in VEGF and pharmacokinetic parameters with changes in FLT PET/CT parameters.

    Measured: Baseline to up day 15 (course 2)

  3. Pharmacokinetic parameters of VEGFR/PDGFR dual kinase inhibitor X-82

    Changes in X-82 pharmacokinetics will be summarized using descriptive statistics. Pearson's or Spearman's rank correlation analysis will be used to correlate changes in VEGF and pharmacokinetic parameters with changes in FLT PET/CT parameters.

    Measured: Within 3 hours prior to X-82 administration on days 1, 12-15, and 19-21 (course 1); and days 12-15 (course 2)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing VEGFR/PDGFR dual kinase inhibitor X-82, docetaxel and fluorine F 18 fluorothymidine in people with Unspecified Adult Solid Tumor, Protocol Specific, run by University of Wisconsin, Madison at 1 site 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 18 inclusion and 29 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 18 Nov 2019. 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 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 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?

Incidence of toxicity graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.0 (Pharmacodynamic study) (time frame: Up to 2 years). The study lists 3 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 NCT02146222, 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 18 Nov 2019.
