Trial summary

Patients who have inoperable non-small cell lung cancer are presently treated with chemotherapy and radiation therapy. Despite this combined approach, the vast majority of patients will have their cancer recur after treatment. A recurrence is not curable at this time. Read more about this study

About this study

Official title: A Phase I/II Dose Escalation Trial Using Hypofractionation With Individualized Differential Boosting With Respiratory Gated Intensity-modulated Radiation Therapy (IMRT) in the Treatment of Non-small Cell Lung Cancer.

Patients who have inoperable non-small cell lung cancer are presently treated with chemotherapy and radiation therapy. Despite this combined approach, the vast majority of patients will have their cancer recur after treatment. A recurrence is not curable at this time. Because of the sensitivity of surrounding structures to chest irradiation, it has not been possible to give radiation doses that can cure many of these tumors. Intensity-modulated radiation therapy is a special form of radiotherapy delivery that allows doctors to reduce the amount of radiation dose to normal tissues and therefore reduce side effects. The reduction of radiation side effects may allow more radiation to be delivered to tumors, therefore improving tumor control and possibly longevity of patients. The purpose of this study is to determine whether the combination of custom designed intensity-modulated radiotherapy (based on individual tumor anatomy) with regular chemotherapy, will be safe enough to allow further intensification of radiation treatment.

Read the detailed description

All patients must have a satisfactory IMRT plan prior to starting radiation therapy, which will commence concurrently with chemotherapy. All patients will be treated to a minimum of 48 Gy in 20 daily fractions over 4 weeks [2.4 Gy per fraction (fx)], to the planning target volume (PTV) defined by pre chemotherapy CT with PET imaging. This is approximately biologically equivalent to a dose of 54 Gy in 27# (5 fractions/week). A differential boosting will then be selected from one of 5 dose escalation schemes. The total individual radiotherapy dose will be prescribed according to the highest dose level that can satisfy all of the set radiotherapy planning constraints for the individual's anatomy. The trial will proceed in 2 phases. In the first phase only the first 3 dose escalation schedules will be used. Once all of these 3 schedules have been deemed safe then dose levels 4 and 5 will be opened up to participation.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Radiotherapy in people with Carcinoma, Non-Small-Cell Lung, run by AHS Cancer Control Alberta at 1 site in Canada.

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 9 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 6 Apr 2016. 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 Canada. 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?

Results are not available in the source record.

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?

Toxicity of treatment (time frame: 90 days (Acute), 5 years (Late)). 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 NCT00690963.

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 6 Apr 2016.
