Scientific titleA dose escalation phase I study of continuous, hyperfractionated, accelerated radiotherapy (CHART) in patients with inoperable non-small cell lung cancer
Study acronymCHART-ED
Study objectivesThe CHART-ED study aims to assess the feasibility of radiotherapy dose-escalation for treating patients with inoperable stage III non-small cell lung cancer (NSCLC).

This study is a multicentre phase I feasibility study. Once completed, a randomised phase II comparison of the dose escalated chemo-radiotherapy CHART-ED schedule with a concurrent chemo-radiotherapy protocol is planned.

As of 01/03/2011 the anticipated end date for this trial has been updated from 31/12/2009 to 01/09/2011
Ethics approval(s)Oxfordshire Research Ethics Committee (REC) A on 21/10/2008 (ref: 08/H0604/147)
Health condition(s) or problem(s) studiedNon-small cell lung cancer (NSCLC)
InterventionPre-study evaluation:
The following baseline assessments need to be performed within the 42 days prior to the radiotherapy planning scan:
1. History (including severity of chronic obstructive airways disease) and examination
2. Respiratory related medication – current and previous history
3. All concurrent medication (e.g., statins, angiotensin converting enzyme inhibitor [ACEI], non-steroidal anti-inflammatory drugs [NSAIDs])
4. Assessment of performance status
5. Assessment of MRC dyspnoea score
7. Chest X-ray (CXR)
8. Positron emission tomography (PET) or co-registered PET-computed tomography (PET-CT) scan
9. CT scan of the thorax and upper abdomen.
Either the CT scan and PET scan (or co-registered PET-CT scan) must be performed within 42 days of the radiotherapy (RT) planning scan.
10. Pulmonary function tests (PFTS) - performed within 14 days of the RT planning CT scan:
10.1. Forced expiratory volume in one second (FEV1)
10.2. Forced vital capacity (FVC)
10.3. Carbon monoxide transfer factor (DLCO) – corrected for haemoglobin (Hb) level
11. Baseline blood tests:
11.1. Haematology: full blood count
11.2. Biochemistry: renal function, liver function, bone profile
12. Electrocardiogram (ECG)
13. Pregnancy test (if applicable)

Interventions:
Radiotherapy dose-escalation.

Dose escalation schedule:
Group 1: 57.6 Gy in 38 fractions, treating 8 hours apart on day 15
Group 2: 61.2 Gy in 40 fractions, treating 8 hours apart on days 15 - 16
Group 3: 64.8 Gy in 42 fractions, treating 8 hours apart on days 15 - 17
Intervention typeOther
Primary outcome measure(s)

The degree of dose escalation achievable. This will be determined by the incidence and grade of potential dose limiting toxicities:
1. Pulmonary toxicity:
1.1. Early radiation pneumonitis (ERTP): occurring within 6 months of finishing RT
1.2. Late radiation pneumonitis (LRTP)/fibrosis: occurring after the six months period following RT
1.3. Changes in pulmonary function tests (PFTs)
2. Oesophageal toxicity:
2.1. Acute oesophagitis: occurring during RT or up to three months post RT
2.2. Chronic oesophagitis/stricture: occurring/persisting beyond three months post-completion of RT
3. Spinal cord toxicity
4. Cardiac toxicity

Toxicity will be assessed at the following post-treatment assessments:
1. Weekly until 1 month post-treatment
2. Monthly until 6 months post-treatment
3. Three-monthly until 2 years post-treatment
4. Six-monthly until 3 years post-treatment
5. Annually until 5 years post-treatment

Key secondary outcome measure(s)

1. Tumour response
2. Two year survival
3. Overall survival
4. Progression free survival
5. Local control

Follow-up visits measuring weight (performance status) and adverse events (dyspnoea score) will occur at the following timepoints:
1. Weekly until 1 month post-treatment
2. Monthly until 6 months post-treatment
3. Three-monthly until 2 years post-treatment
4. Six-monthly until 3 years post-treatment
5. Annually until 5 years post-treatment

In addition, the following investigations will be requested:
1. CXR: at months 1, 2, 5, 12, 18, 24 post-treatment
2. CT chest/abdomen: at months 3 and 6 post-treatment
3. PFTs: at months 3, 6 and 12 post-treatment
4. ECG: at months 6 and 12 post-treatment

Appropriate investigations and assessments will be performed if the patient becomes symptomatic in between trial follow-up appointments.
