About this study

Official title: Phase II Trial Of Neoadjuvant Bevacizumab With Modified FOLFOX7 In Patients With Stage II And III Rectal Cancer

This phase II trial studies how well bevacizumab, fluorouracil, leucovorin calcium, and oxaliplatin before surgery works in treating patients with stage II-III rectal cancer. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as fluorouracil, leucovorin calcium, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab together with fluorouracil, leucovorin calcium, and oxaliplatin may be an effective treatment for rectal cancer.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine if six cycles of modified fluorouracil, leucovorin calcium, and oxaliplatin (mFOLFOX7) plus bevacizumab (Avastin) will yield complete pathologic response (cPR) of 25% or more in the primary tumor of patients with stage II and III rectal cancer.

SECONDARY OBJECTIVES:

  1. To assess the rate of tumor regression (pathologic stage lower than clinical stage) after 6 cycles of mFOLFOX7 and bevacizumab in the primary rectal cancer.

II. To assess local recurrence rate over 3 years after 6 cycles of mFOLFOX7 and bevacizumab.

TERTIARY OBJECTIVES:

  1. Correlation of the following marker with response (defined as CPR or down staging):
  • Intratumoral Gene expression and germline polymorphism of genes involved in the vascular endothelial growth factor (VEGF) and VEGF independent pathways (VEGF, vascular endothelial growth factor receptor 1 [VEGFR1], VEGFR2, interleukin-8 [IL8], chemokine (C-X-C motif) receptor 2 [CXCR2], intercellular adhesion molecule [ICAM], VEGFR1 and VEGFR2, neuropilin 1 or 2 [NRP1,2], cluster of differentiation [CD] 44, aldehyde dehydrogenase [ALDH], leucine-rich repeats and immunoglobulin-like [LRIG].
  • Circulating tumor cells (CTC) and VEGF-factor A (A) on the CTC.

II. Prediction of surgical resection margin by pretreatment magnetic resonance imaging (MRI).

OUTLINE:

Patients receive bevacizumab intravenously (IV) over 30-90 minutes, oxaliplatin IV over 2 hours, leucovorin calcium IV, and fluorouracil IV continuously over 46-48 hours on day 1. Treatment repeats every 14 days for 6 courses in the absence of disease progression or unacceptable toxicity. Within 6-8 weeks after treatment, patients undergo surgery.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

What is being measured

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

  1. Number of Participants With Pathological Complete Response (pCR) to Neoadjuvant Therapy

    Pathological Complete Response (pCR) after neoadjuvant therapy in pathological specimen. Pathological Complete Response (pCR) is the absence of all invasive cancer in the breast and lymph nodes after neoadjuvant therapy, meaning all cancer cells are eliminated. This outcome is a strong predictor of improved survival. Evaluating pCR provides a rapid assessment of a patient's likely response to therapy and can help guide future treatment decisions.

    Measured: Up to 3 years

Secondary outcomes (5)
  1. Tumor Regression on Mesorectal Margins (Pathologic Stage Lower Than Clinical Stage)

    Measured: Up to 3 years

  2. Rate of Locoregional Recurrence

    Number of cancer patients who experience a return of their cancer in the original tumor site or in the nearby lymph nodes following initial treatment. It is a measure of how often cancer returns to the local area where it started, rather than spreading to distant organs.

    Measured: Up to 3 years

  3. Number of Participants With Adverse Events (AEs)

    Incidence and nature of adverse events (AEs) according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 ( v4)

    Measured: Up to 3 years

  4. Number of Participants With Serious AEs (SAEs) According to NCI CTCAE v4.0

    Measured: Up to 3 years

  5. Number of Participants of AEs of Special Interest for Bevacizumab (Grades) According to NCI CTCAE v4.0

    Measured: Up to 3 years

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 17 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: stopped early, as of the sponsor's last update on 1 Jul 2026. 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 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 1 Jul 2026). 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?

Number of Participants With Pathological Complete Response (pCR) to Neoadjuvant Therapy (time frame: Up to 3 years). 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 NCT01871571, 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 1 Jul 2026.
