About this study

Official title: A Phase II Study to Assess the Safety and Efficacy of the Combination of Carboplatin, Paclitaxel, and Bevacizumab ± Combretastatin A4 Phosphate (CA4P) Followed by Bevacizumab ± CA4P in Subjects With Chemotherapy Naïve Stage IIIB/IV Non-Squamous Cell Histology Non-Small Cell Lung Cancer (NSCLC)

The purpose of this study is to determine the safety, tolerability and efficacy of combretastatin A4 phosphate (CA4P), also known as fosbretabulin, in combination with bevacizumab (Avastin), carboplatin and paclitaxel in patients with chemotherapy naïve non-small cell lung cancer (NSCLC). This is a randomized parallel arm study. All participants will receive carboplatin, paclitaxel and bevacizumab, and half will additionally receive CA4P. Patients who complete the first 6 cycles of therapy and have not experienced disease progression will receive maintenance therapy with bevacizumab alone or with bevacizumab plus CA4P.

The rationale for this study is the potential additive or synergistic actions of vascular disrupting agents like CA4P with anti-angiogenic agents like bevacizumab.

Read the detailed description

Lung cancer has become the leading cause of cancer death in both men and women in the US and Europe, accounting for 29% of all cancer deaths. Non-Small Cell Lung cancer (NSCLC) accounts for approximately 80% of all lung cancer cases. Currently, no curative treatment is available for advanced stages of the disease (stages III and IV), which comprise the majority of cases. Treatment with the combination of carboplatin and paclitaxel has been shown to be effective and well tolerated in advanced stage NSCLC. Targeted therapies, such as bevacizumab, often act synergistically with chemotherapy. Bevacizumab inhibits vascular endothelial growth factor (VEGF), necessary for endothelial cell proliferation and new blood vessel formation. CA4P targets existing abnormal vasculature of tumors, impeding tumor blood flow and leading to extensive tumor cell death as a consequence of oxygen and nutrient deprivation.

This study will compare the effect of CA4P when combined with chemotherapy and bevacizumab on progression free survival (PFS) to PFS after chemotherapy and bevacizumab alone.

What is being measured

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

  1. Progression Free Survival (PFS) in the Intent-to-Treat Population

    Progression was defined using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.0. Based on 20% increase of the longest diameter of target lesions or appearance of one or more new non-target lesions or/and progression of non-target lesions since the treatment started.

    Measured: Six 21-day cycles

Secondary outcomes (5)
  1. Best Overall Tumor Response Rate (RR) in the Intent-to-Treat Population

    Based on Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.0 for target lesions (assessed by MRI or CT scan): Complete Response (CR) is defined as the disappearance of all target lesions, Partial Response (PR) is defined as at least a 30% decrease in the sum of the longest diameter of target lesions, Progressive Disease is defined as at least 20% increase in the sum of the longest diameter of target lesions, Stable Disease (SD) is defined as neither shrinkage to qualify for a PR or increase to qualify for a PD.

    Measured: Six 21-day cycles

  2. Overall Survival (OS) Using a Multivariate Cox Regression Model in the Intent-to-Treat Population

    Measured: Until death or lost to follow-up, up to 12 months since randomization

  3. Chemistry NCI-CTCAE Toxicity Grade of 3 or 4 (Safety Population)

    Measured: Days 1 (pretreatment) per 21-day Cycle (6 Cycles)

  4. Hematology NCI-CTCAE Grade 3 or 4 (Safety Population)

    Measured: Days 1 (pretreatment), 7, 14, and 21 per 21-day Cycle (6 Cycles)

  5. Coagulation NCI-CTCAE Grade 3 or 4 (Safety Population)

    Measured: Day 1 (pretreatment) per 21-day Cycle (6 Cycles)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Fosbretabulin, Carboplatin and Paclitaxel in people with Tumors, run by Mateon Therapeutics at 15 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 6 inclusion and 11 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 9 Feb 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 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 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 9 Feb 2015). 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?

Progression Free Survival (PFS) in the Intent-to-Treat Population (time frame: Six 21-day cycles). 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 NCT00653939, which also lists 7 linked publications.

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.
