About this study
Official title: Phase I Trial of FOLFIRI in Combination With Sorafenib and Bevacizumab in Patients With Advanced Gastrointestinal Malignancies
This phase I trial studies the side effects and best dose of sorafenib tosylate when given together with bevacizumab, irinotecan hydrochloride, leucovorin calcium, and fluorouracil in treating patients with colorectal cancer that has spread to other parts of the body. Drugs used in chemotherapy, such as irinotecan hydrochloride, leucovorin calcium, and fluorouracil, 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. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. Sorafenib tosylate and bevacizumab may also block tumor growth in different ways by targeting certain cells. Giving sorafenib tosylate and bevacizumab together with combination chemotherapy may be a better treatment for colorectal cancer.
Read the detailed description
PRIMARY OBJECTIVES:
- To determine the maximally tolerated dose of the combination of irinotecan hydrochloride, leucovorin calcium, and fluorouracil (FOLFIRI) plus sorafenib (sorafenib tosylate) plus bevacizumab.
SECONDARY OBJECTIVES:
- To assess the safety of FOLFIRI plus sorafenib plus bevacizumab. II. To assess the feasibility of the proposed combination. III. To evaluate the response rate and identify any activity of the proposed combination.
OUTLINE: This is a dose-escalation study of sorafenib tosylate followed by a cohort study. (Cohort study cancelled as of March 25, 2014)
Patients receive irinotecan hydrochloride intravenously (IV) over 90 minutes on day 1, leucovorin calcium IV over 2 hours on day 1, fluorouracil IV continuously over 46 hours on days 1-2, bevacizumab IV over 30-90 minutes on day 1, and sorafenib tosylate orally (PO) once (QD) or twice daily (BID) on days 3-6 and 10-13*. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.
NOTE: *Patients may also receive sorafenib tosylate on days 7 and 14.
After completion of study therapy, patients are followed up for 3 months.

What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum tolerated dose of sorafenib tosylate in combination with FOLFIRI and bevacizumab, defined as the dose level below the lowest dose that induces dose-limiting toxicity in at least one-third of patients (at least 2 of a maximum of 6 new patients)
Graded using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0
Measured: 14 days
Secondary outcomes (7)
Incidence of adverse events of sorafenib tosylate in combination with bevacizumab and FOLFIRI as assessed by NCI CTCAE v 4.0
The number and severity of all adverse events (overall, by dose-level, and by tumor group) will be tabulated and summarized in this patient population. The grade 3+ adverse events will also be described and summarized in a similar fashion.
Measured: Up to 3 months
Response rate in patients treated with sorafenib tosylate in combination with FOLFIRI and bevacizumab, assessed using Response Evaluation Criteria in Solid Tumors
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 (overall and by tumor group).
Measured: From the start of the treatment until disease progression/recurrence, assessed up to 3 months
Time to progression
Measured: Up to 3 months
Time to treatment failure
Measured: Time from registration to documentation of progression, unacceptable toxicity, or refusal to continue participation by the patient, assessed up to 3 months
Time to until treatment related grade 3+ toxicity assessed via CTC standard toxicity grading
Will be assessed using continuous variables as the outcome measures (primarily nadir). 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
Time until any treatment related toxicity evaluated via the ordinal Common Toxicity Criteria (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
Time until hematologic nadirs (ANC, platelets, hemoglobin)
Descriptive statistics and simple scatter plots will form the basis of presentation of these data.
Measured: Up to 3 months

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Bevacizumab, Fluorouracil and Irinotecan Hydrochloride in people with Recurrent Colon Carcinoma and Recurrent Rectal Carcinoma, run by National Cancer Institute (NCI) 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 18 inclusion and 35 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 19 Apr 2017. 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 of sorafenib tosylate in combination with FOLFIRI and bevacizumab, defined as the dose level below the lowest dose that induces dose-limiting toxicity in at least one-third of patients (at least 2 of a maximum of 6 new patients) (time frame: 14 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 19 Apr 2017.
