About this study

Official title: Phase 1 Study of Pazopanib in Combination With Irinotecan and Temozolomide (PAZIT) for Children and Young Adults With Relapsed or Refractory Sarcoma

This is the first study to evaluate the safety and clinical activity of the combination of oral pazopanib, intravenous or oral irinotecan, and oral temozolomide in pediatric and young adult patients with relapsed or refractory sarcomas. This study will use a 3 + 3 design for dose escalation (Part 1), followed by an expansion cohort (Part 2) at the recommended phase 2 dose level.

Read the detailed description

The combination of irinotecan and temozolomide is well-tolerated and provides an active therapy option for heavily pre-treated patients with sarcoma. The toxicity profile and activity level suggest that this combination will provide a useful platform onto which novel compounds may be added. Pazopanib has been shown to demonstrate single-agent activity in sarcomas in the preclinical and clinical settings. Pazopanib has also been shown to have additive or synergistic effects in preclinical models of sarcomas when combined with cytotoxic chemotherapy. Pharmacokinetic studies of pazopanib and irinotecan as well as pharmacodynamic studies of pazopanib to assess anti-angiogenesis will be performed. Exploratory studies to assess non-invasive methods of monitoring tumor response [circulating tumor DNA and functional imaging by positron emission tomography (PET)/magnetic resonance imaging (MRI) will be performed].

What participants receive

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

  • PazopanibDrug

    Pazopanib will be administered orally as a tablet according to an assigned dose level per protocol. A cycle will be defined as 21 days. Drug dosing for the tablet formulation will be determined using a study-specific nomogram.

  • IrinotecanDrug

    Patients will be given irinotecan at a dose of 25 mg/m2/dose IV on days 1-5 of a 21-day cycle during Cycle 1. In subsequent cycles, irinotecan may be given intravenously at a dose of 25 to 37.5 mg/m2/dose or orally at a dose of 45 to 67.5 mg/m2/dose on days 1-5 of a 21-day cycle.

    Note that some patients enrolled on an earlier protocol version received 50 mg/m2/dose IV on days 1-5 of the first 21-day cycle and then either 50 mg/m2/dose IV or 90 mg/m2/dose orally for subsequent 21-day cycles. This higher dose level is no longer being given to newly enrolled subjects.

  • TemozolomideDrug

    Temozolomide will be given at a dose of 100 mg/m2/dose orally on days 1-5 of each 21-day cycle.

Study groups in NCT03139331
Study groupRoleWhat they receive
Pazopanib, irinotecan, temozolomide (PAZIT)ExperimentalPatients will receive daily oral pazopanib on days 1-21 in a 21-day cycle. This will be combined with intravenous or oral irinotecan and oral temozolomide on days 1-5. Dosing of irinotecan will be from 25 to 37.5 mg/m2/day for IV dosing or from 45 to 67.5 mg/m2/dose for oral dosing and oral temozolomide will be 100 mg/m2/day for dose levels at each assigned dose level. In the absence of disease progression or unacceptable toxicity, patients will receive cycles of therapy repeating every 21 days for a maximum of 12 months on study.
Receives: Drug: Pazopanib; Drug: Irinotecan; Drug: Temozolomide

What is being measured

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

  1. Maximum Tolerated Dose

    Maximum tolerated dose or recommended phase 2 dose of pazopanib administered in combination with irinotecan and temozolomide

    Measured: 3 weeks

  2. Number of Patients with Dose-Limiting Toxicities (DLTs) Using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0

    Toxicity will be graded using the CTCAE criteria, version 4.0. DLT will be defined as any of the events as defined per the protocol that are at least possibly, probably, or definitely attributable to the combination of pazopanib, irinotecan, and temozolomide. DLTs are generally grade 3 or greater in severity.

    Dose limiting hematological and non-hematological toxicities are defined differently, per the protocol.

    Measured: 3 weeks

  3. Describing toxicities of PAZIT drug combination using NCI CTCAE Version 4.0

    To describe any toxicities associated with the combination of pazopanib, irinotecan and temozolomide (PAZIT).

    Measured: 3 weeks

Secondary outcomes (3)

  1. Objective Response Rate Using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

    The best overall response is the best response recorded from the start of the treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started). The patient's best response assignment will depend on the achievement of both measurement and confirmation criteria. Tumor response will be assessed using RECIST version 1.1.

    Measured: From treatment initiation until disease progression, an average of about 6 months

  2. Progression-Free Survival (PFS) Using RECIST Version 1.1

    PFS is defined as the duration of time from start of treatment to time of tumor progression. Tumor response will be assessed using RECIST version 1.1.

    Measured: From treatment initiation until disease progression, an average of about 6 months

  3. Overall Survival (OS)

    OS is defined as the duration of time from start of treatment to time of death from any cause.

    Measured: From treatment initiation until death, an average of about 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Pazopanib, Irinotecan and Temozolomide in people with Sarcoma and Refractory Sarcoma, run by University of California, San Francisco at 3 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 53 inclusion and 28 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 5 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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?

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?

Maximum Tolerated Dose (time frame: 3 weeks). 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 NCT03139331.

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 5 Jan 2021.
