Trial summary

The well-established role of vascular endothelial growth factor (VEGF) in carcinogenesis and tumor angiogenesis has led to the development of agents that target this pathway. Anti-VEGF agents the VEGF monoclonal antibody bevacizumab, and the small molecule VEGF receptor tyrosine kinase inhibitors. Read more about this study

About this study

Official title: A Study of the Pharmacodynamic Effects of Anti-vascular Endothelial Growth Factor Therapy in Patients With Advanced Malignancies

The well-established role of vascular endothelial growth factor (VEGF) in carcinogenesis and tumor angiogenesis has led to the development of agents that target this pathway. Anti-VEGF agents the VEGF monoclonal antibody bevacizumab, and the small molecule VEGF receptor tyrosine kinase inhibitors. Angiogenic factors play a key role in the maintenance of lung integrity and normal endothelial function. Endothelial dysfunction has been implicated in hypertension, proteinuria and retinopathy. One of the major issues of anti-VEGF agents is its long-term toxicity especially taking into account the lack of adequate knowledge in this area and the possibility of prolonged periods of therapy in non-progressing patients. Hypertension and proteinuria are commonly seen in patients treated with anti-VEGF agents. In addition, the investigators have also observed in a relatively high frequency of pulmonary air-filled lesions in patients with malignancy in the lung treated with an anti-VEGF agent. Objectives of this exploratory study are to 1) determine the effect of anti-vascular endothelial growth factor (VEGF) on endothelial function 2) determine endothelial dysfunction as a marker of early response and as an indicator for the development of hypertension and proteinuria 3) characterize the effect of anti-VEGF therapy on the pulmonary function of patients with malignancy (primary or secondary) involving the lung in patients treated with anti-VEGF agents. Pharmacodynamic endpoints to be assessed are: blood pressure, brachial artery reactivity, retinal microvessels, microalbuminuria and proteinuria, pulmonary function, assess the effects of anti-VEGF therapy by assessing brachial artery reactivity, retinal vasculature and pulmonary function in a subset of patients receiving anti-VEGF therapy. The development of markers of endothelial dysfunction may result in the early identification of patients who are non-responders or develop toxicity from anti-VEGF treatment.

Questions about this trial

What is this clinical trial studying?

An observational study of Advanced Malignancy, run by National University Hospital, Singapore at 1 site in Singapore.

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 5 inclusion and 1 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 Apr 2010. 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 Singapore. 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.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00978926, which also lists 2 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.

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 9 Apr 2010.
