We need your help to advance medical research

You can help accelerate the discovery of cures of medical conditions by signing up and creating a profile. By doing so you can register your interest in clinical trials and researchers will be able to get in touch about trials that are suitable for you.

This information is designed to help you decide whether this trial is of interest. In some cases it is provided as a link to more detailed patient information or it may still be awaited from the organisation running the trial. Please look again shortly if the information you need is not here or, if named, contact the researcher named above.
Summary
The I-START trial is designed to determine the highest doses of radiotherapy that can safely be used in locally advanced non-small cell lung cancer (NSCLC). Patients with NSCLC who are expected to live longer than three months and are fit to receive radical radiotherapy (radiotherapy given with curative intent) will be eligible to participate. All trial participants will receive 20 doses (called fractions) of radiotherapy. Evidence is available that suggests increasing the dose of radiotherapy given per fraction may improve both local control of the cancer and survival in some patients. However, high dose radiotherapy can damage normal tissues as well as the tumour. The dose of radiotherapy that can be used to treat lung cancer is limited by the normal tissues close to the cancer. For most of these normal tissues (lung, spinal cord and heart) the maximum safe radiotherapy dose that can be given is known. The maximum safe dose of radiotherapy for the oesophagus (gullet) is not currently known.

The trial will be split into two parts:

1. For those participants where the oesophagus will receive a high dose of radiation due to it lying close to the cancer, the first part of the trial will establish the maximum safe dose of radiotherapy to the oesophagus. The first group of participants will receive a slightly higher dose than is currently used to treat lung cancer. If these participants do not have any significant side effects, a second group of participants will receive a slightly higher dose than the first group. This process will continue incrementally until side effects from the treatment become evident, thus demonstrating the maximum dose that can safely be given. Once the maximum safe dose to the oesophagus is known this will be classed as the recommended Phase II dose and all further patients entering the trial will receive no more than this dose to the oesophagus.

2. For those participants where the cancer is a safe distance from their oesophagus, the highest dose of radiotherapy that does not exceed the known safe dose limits of the normal structures (lung, spinal cord and heart) will be used.

The findings of both parts of this study will determine whether increasing the dose of radiotherapy for NSCLC patients is a tolerable, safe and effective treatment. If the results are positive then this new treatment may be compared against the best currently available standard treatments in a future larger randomised (Phase III) trial.
Research Details
  • Main inclusion criteria:

    3. Disease which can be encompassed within a radical radiotherapy treatment plan in keeping with standard practice at the participating centre

    4. WHO Performance Status 0 or 1 (Appendix III)

    5. Adequate respiratory function: FEV1 ≥ 1.0 litre, DLco (transfer factor) ≥ 40% of predicted and Kco (DLco/VA) > 40% predicted on baseline lung function tests

    9. Considered fit to receive trial treatment

    10. Estimated life expectancy of more than 3 months

    11. Written informed consent obtained

    12. Patient consents for electronic CT scan and planning data to be used for future research

    Main exclusion criteria:

    1. Medically unstable (e.g. unstable diabetes, uncontrolled hypertension, infection, hypercalcaemia or very symptomatic ischaemic heart disease)

    2. Previous or current malignant disease likely to interfere with protocol treatment

    3. Pancoast tumours

    4. Connective tissue disorders (e.g. Scleroderma, Systemic Lupus Erythematosus)

    5. Interstitial lung disease

    6. Women who are pregnant or lactating

    7. Women of childbearing potential who are not using adequate contraceptive precautions

    Primary outcome measure:

    Phase I:

    • Establish the maximum tolerated dose (MTD) to the oesophagus to use as the recommended Phase II dose.

    Phase II:

    • Toxicity rate (grade 3 and 4) at three months.

    Secondary outcome measures

    Phase I:

    • Chronic oesophagitis or stricture occurring/persisting two months or more after completion of radiotherapy

    Phase II:

    - Local control at three months (to include complete response, partial response and stable disease)

    - Feasibility

    - Time to Local Progression; measured in days from the day of trial entry to the date of first clinical evidence of progressive disease at the primary site

    - Time to distant metastases measured in days

    - Overall Survival; measured in days, from the day of trial entry to the day of death (from any cause)

    - Toxicity; pulmonary, oesophageal, spinal cord and cardiac grade 3 or 4 toxicity occurring up to three months after radiotherapy

    - Radiotherapy Quality Assurance. A detailed QA program will be in place to ensure adherence to the protocol. Major and minor deviations will be documented
