Study information

Scientific title

A phase I/II multicentre interventional trial of concurrent chemoradiation with dose-escalated radiotherapy in patients with stage II or stage III non-small cell lung cancer



Study hypothesis

The aim of IDEAL-CRT is to investigate the toxicity, feasibility and potential clinical effectiveness of dose-escalated radiotherapy (RT) with concurrent chemotherapy in stage IIb or stage III non-small cell lung cancer (NSCLC) as a potential experimental arm in future phase III trials. It will also allow the assessment and validation of radiobiological models for predicting tumour control and normal tissue complications.

Please note, as of 03/11/2011 updates have been made to the trial record and can be found under this date in the relevant fields below.
Both start and end dates for this trial have been updated. The dates at time of registration were as follows:
Original start date: 01/12/2009
Original end date: 01/12/2011

Ethics approval

Non-small cell lung cancer


Dose escalation will be through an individual patient-based model, associated with an acceptable level of grade 3 toxicity (from oesophagus or lung).

Radiotherapy (30 single daily fractions to planning target volume [PTV]) for six weeks given concurrently with standard chemotherapy (2 cycles of cisplatin and vinorelbine).

On-treatment assessments:
1. Weekly for 6 weeks

Post-treatment assessments:
2. Weekly until 1 month post RT, then
3. Monthly until 6 months post RT, then
4. 3-monthly until 2 years post RT, then
5. 6-monthly until 3 years post RT, then
6. Annually

Intervention type



Phase I/II

Drug names

Cisplatin, vinorelbine

Primary outcome measures

Current primary outcome measures as of 03/11/2011:
Grade 2-5 according to Common Terminology Criteria for Adverse Events v4.0 (CTCAE v4.0 - appendix 1) acute oesophagitis during RT or within 3 months from the first dose of RT for all patients.

Early Radiation Pneumonitis (ERTP) determined by grade 2 - 5 according to CTCAE v4.0 toxicity rates occurring within 6 months from the first dose of RT for all patients.

Previous primary outcome measures:
Grade 2 - 5 according to Common Terminology Criteria For Adverse Events v4.0 (CTCAE v4.0) acute oesophagitis during RT or within 6 months from the first dose of RT rate for all patients. In IDEAL-CRT this will be used for 6 months post-RT.

Secondary outcome measures

Current secondary outcome measures as of 03/11/2011:
Chronic oesophageal stricture rate: grade 1 - 5 according to Radiation Therapy Oncology Group (RTOG) late toxicity scales from 3 months post-RT for all patients.

1. Pneumonitis grades 2 - 5 (CTCAE v4.0) 6 or more months after end of RT for all patients
2. Changes from baseline in FEV1, forced vital capacity (FVC) and DLCO (CTCAE v4.0 grades 2 - 5)
3. Any grade 2 - 5 pulmonary toxicity according to CTCAE v4.0 from start of RT to death

Previous secondary outcome measures:
3. Any grade 2 - 5 pulmonary toxicity according to CTCAE v4.0 from start of RT to 12 months post-RT

6. Radiotherapy dose constraints consistent with minimum prescription dose of 63 Gy in 30 fractions
7. Age 18 or over (no upper age limit), either sex
8. No prior thoracic radiotherapy
9. No prior lobectomy/pneumonectomy
10. No prior systemic chemotherapy
11. Willing and able to give informed consent
