About this study

Official title: Pharmacokinetic-Driven Individualization of Pazopanib Therapy in Patients With Solid Tumors: A Phase I Study

This phase I trial studies the side effects and the best dose of pazopanib hydrochloride in treating patients with solid tumors that has spread to other places in the body and usually cannot be cured or controlled with treatment (advanced) or does not respond to treatment (refractory). Pazopanib hydrochloride may prevent the growth of new blood vessels that tumors need to grow. Studying samples of blood in the laboratory from patients receiving pazopanib hydrochloride may help doctors learn more about the effects of the body on the drug. It may also help doctors understand how well patients respond to treatment.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To assess the feasibility and safety of individualizing pazopanib (pazopanib hydrochloride) monotherapy based upon attained pazopanib plasma concentrations so as to achieve desired target pazopanib plasma concentration in the highest possible fraction of treated patients.

SECONDARY OBJECTIVES:

  1. To assess whether patient cytochrome P450 (CYP) or other polymorphisms may correlate with attained pazopanib levels in response to standard pazopanib dosing.

II. To assess whether patient trough pazopanib levels attained 24 hours after initiation of 800 mg daily fasting may predict steady state trough pazopanib levels after 14 days of pazopanib administration.

III. To assess whether patient trough pazopanib levels may correlate with observed pazopanib toxicities.

OUTLINE: This is a dose-escalation study.

Patients receive pazopanib hydrochloride orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Course length can be extended to 56 days at the discretion of the treating physician after 12 courses (1 year) of treatment on study.

After completion of study treatment, patients are followed up for 3 months.

What is being measured

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

  1. Biologically optimal dose (BOD) defined as the dose level and diet in combination that induces no toxicity requiring dose modification per protocol and achieves a satisfactory pazopanib trough concentration (Cmin greater than 30 ug/mL)

    Measured: At 14 days

  2. Adverse events profile, as assessed by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0

    The number and severity of all adverse events (overall, by dose-level and diet, and by tumor group) will be tabulated and summarized.

    Measured: Up to 3 months

  3. Incidence of grade 3+ adverse events, as assessed by the NCI CTCAE version 4.0

    The number and severity of grade 3+ adverse events will be tabulated and summarized.

    Measured: Up to 3 months

  4. Toxicity profile, as assessed by the NCI CTCAE version 4.0

    Non-hematologic toxicities will be evaluated via the ordinal CTC standard toxicity grading. Hematologic toxicity measures of thrombocytopenia, neutropenia, and leukopenia will be assessed using continuous variables as the outcome measures (primarily nadir) as well as categorization via CTC standard toxicity grading. Overall toxicity incidence as well as toxicity profiles by dose level, patient and tumor site will be explored and summarized. Frequency distributions, graphical techniques and other descriptive measures will form the basis of these analyses.

    Measured: Up to 3 months

  5. Response profile, assessed using modified Response Evaluation Criteria in Solid Tumors (RECIST)

    Responses will be summarized by simple descriptive summary statistics delineating complete and partial responses as well as stable and progressive disease in this patient population The summary will be overall and by tumor group, and particularly by cohorts (first 34 patients vs. expansion cohort where a possibly refined definition of disease progression will be used).

    Measured: Up to 3 months

  6. Time until any treatment-related toxicity, as assessed by the NCI CTCAE version 4.0

    Measured: Up to 3 months

  7. Time until treatment-related grade 3+ toxicity, as assessed by the NCI CTCAE version 4.0

    Measured: Up to 3 months

  8. Time until hematologic nadirs (ANC, platelets, hemoglobin) , as assessed by the NCI CTCAE version 4.0

    Measured: Up to 3 months

  9. Time to progression according to RECIST version 1.1

    Measured: Up to 3 months

  10. Time to treatment failure

    Measured: From registration to documentation of progression, unacceptable toxicity, or refusal to continue participation by the patient, assessed up to 3 months

Secondary outcomes (3)

  1. Pazopanib hydrochloride levels attained in response to standard dosing

    Descriptive statistics, simple scatter plots and linear regression model will form the basis of presentation of these data. Attained levels will be correlated with cytochrome P450 and other polymorphisms and with observed toxicities.

    Measured: At baseline, at 24 hours after pazopanib hydrochloride and day 14 of course 1, and at 14 days of dosage change

  2. Steady state pazopanib hydrochloride trough levels

    Descriptive statistics, simple scatter plots and linear regression model will form the basis of presentation of these data. Will be correlated with steady state trough levels after 14 days.

    Measured: 24 hours after initiation of 800 mg daily fasting

  3. Trough pazopanib hydrochloride levels

    Descriptive statistics, simple scatter plots and linear regression model will form the basis of presentation of these data. Trough levels will be correlated with observed toxicities.

    Measured: After 14 days of pazopanib hydrochloride administration

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Laboratory Biomarker Analysis, Pazopanib Hydrochloride and Pharmacological Study in people with Solid Neoplasm, run by National Cancer Institute (NCI) at 2 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 21 inclusion and 56 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: under way, not looking for participants, as of the sponsor's last update on 9 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 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?

This study is still under way. Results are not available in the source record yet.

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?

Biologically optimal dose (BOD) defined as the dose level and diet in combination that induces no toxicity requiring dose modification per protocol and achieves a satisfactory pazopanib trough concentration (Cmin greater than 30 ug/mL) (time frame: At 14 days). The study lists 10 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 NCT01552356.

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 9 Sep 2026.
