About this study

Official title: X-TRAP: Phase I/II Study of Capecitabine Plus Aflibercept in Metastatic Colorectal Cancer

The Primary Phase I objectives are to determine the recommended phase II dose for the capecitabine and aflibercept doublet combination; and to describe any dose limiting and non-dose limiting toxicities. The Phase II Primary objective is to determine progression free survival associated with this regimen. The Phase II secondary objectives are to determine response rate associated with this regimen; to determine overall survival associated with this regimen; and to explore any correlation of clinical outcome with baseline and on treatment changes in blood-based angiogenesis biomarkers.

This open-label, non-randomized phase I/II trial is designed to assess the safety, tolerability and RPTD of capecitabine plus aflibercept in adult subjects with metastatic colorectal cancer.

What participants receive

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

  • Capecitabine and afliberceptDrug

    Capecitabine given on days 1-14 and off days 15-21. Dose: Phase 1 cohort 1 850mg/m2 Phase 1 cohort 2 1000mg/m2, Phase 2 RPTD.

    Aflibercept will be held constant at 6 mg/kg, given intravenously every 3 weeks.

    Both agents will be administered on a 21-day cycle.

Study groups in NCT01661972
Study groupRoleWhat they receive
Phase 1: Capecitabine and AfliberceptExperimentalA standard 3+3 dose escalation format will be used. Capecitabine will start at 850mg/m2 to be given on days 1-14 and off days 15-21. If tolerated, the dose will then be escalated to 1000mg/m2 for the next cohort, given on the same schedule. The dose of aflibercept will be held constant at 6 mg/kg, given intravenously every 3 weeks.
Receives: Drug: Capecitabine and aflibercept
Phase 2: Capecitabine and AfliberceptExperimentalOnce the RPTD of the doublet combination has been identified, an additional 50 subjects with metastatic colorectal cancer will be added to a single, Phase 2 arm
Receives: Drug: Capecitabine and aflibercept

What is being measured

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

  1. Recommended Phase II Dose (RPTD) for the Capecitabine and Aflibercept Doublet Combination

    Phase 1 of this study will be the dose escalation component to determine safety and the Recommended Phase II dose (RPTD) for the capecitabine plus aflibercept combination. Cohort 1 will receive 850mg/m2 capecitabine and 6mg/kg aflibercept. If less than 2 of 6 patients experience a dose limiting toxicity in Cohort 1, then the next patients will be enrolled in Cohort 2 at 1000mg/m2 capecitabine and 6mg/kg aflibercept. RPTD is determined by the number of dose limiting toxicities (Primary obj 2 for Phase I).

    Measured: RPTD for the study will be determined at the completion of Phase I; up to 1 year.

  2. Number of Dose-Limiting Toxicities (Phase 1)

    Number of patients experiencing a dose-limiting toxicity in each cohort.

    A dose-limiting toxicity is defined as Grade 4 neutropenia, thrombocytopenia or anemia or grade 3 neutropenia or thrombocytopenia lasting over 7 days Grade 3 thrombocytopenia associated with bleeding Febrile Neutropenia Nausea/Vomiting or Diarrhea ≥ grade 3 and lasting ≥ 4 days despite adequate supportive measures Grade ≥ 3 Bilirubin, ALT or AST > 7 days Other non-hematologic toxicity ≥ grade 3 excluding alopecia, anorexia, fatigue, hypertension, isolated lab abnormalities (not clinically significant) and/ rare, idiosyncratic reactions to any of the study drugs. Anorexia, fatigue and hypertension will be considered as DLT only if they reach grade 4 or are considered unmanageable Treatment delay of ≥ 14 days for cycle 2 due to unresolved toxicity Treatment-related death or clinically significant,treatment-related hospitalization

    Measured: 28 days

  3. Median Progression Free Survival (PFS)

    Time in months from the start of study treatment to the date of first progression (PD) according to the RECIST criteria, or death due to any cause. Per RECIST criteria, a PD is indicated when there is at least a 20% increase in the sum of the longest diameters from target lesions relative to the smallest sum recorded since treatment is initiated. Median PFS was estimated using a Kaplan-Meier curve, and is the time at which 50% of patients remain alive without disease progression.

    Measured: approximately 5 months

Secondary outcomes (2)
  1. Response Rate

    The percentage of patients for whom the best overall response is complete response (CR) or partial response (PR). A CR occurs when all lesions disappear; whereas, a PR is indicated when there is at least a 30% decrease in the sum of the longest diameters (LD) of the target lesion. A PD (progressive disease) occurs when there is at least a 20% increase in the sum of the LD relative to the smallest sum LD recorded since treatment is initiated. Disease is considered stable if there is no response and no PD. All patients were assigned a best response for inclusion in this calculation in accordance with the protocol.

    Measured: approximately every 9 weeks and/or restaging, through study completion

  2. Median Survival

    Time in months from the start of study treatment to date of death due to any cause. Median survival was estimated using a Kaplan-Meier curve and is the time point at which 50% of patients remain alive.

    Measured: Subjects will be followed until death which is estimated to be on average 6 months - 1 year after coming off protocol therapy

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Capecitabine and aflibercept in people with Metastatic Colorectal Cancer, run by John Strickler, M.D. 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 19 inclusion and 13 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 29 Oct 2018. 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 combined 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.

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 11 Jul 2017). 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?

Recommended Phase II Dose (RPTD) for the Capecitabine and Aflibercept Doublet Combination (time frame: RPTD for the study will be determined at the completion of Phase I; up to 1 year.). 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 NCT01661972, 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 29 Oct 2018.
