Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Phase 1 - dose escalation trial of stereotactic ablative radiotherapy (SABR).

Each dose arm delivers a tumour dose biologically equivalent to the conventional regime of 60 Gy in 30 fractions over 6 weeks.

Arm 1 - 50.4 Gy in 12 fractions over 2.5 weeks
Arm 2 - 46 Gy in 8 fractions over 2-3 weeks
Arm 3 - 42 Gy in 6 fractions over 2-3 weeks

Treatment will be prescribed by the treating radiation oncologist after a discussion at a multidisciplinary meeting. Treatment will be administered in the radiotherapy department at the hospital. During the SABR treatment you will be lying on a treatment couch whilst the radiation machine moves around you delivering the radiation. Prior to the treatment beginning the treatment staff will carry out imaging procedures to ensure the radiation is delivered accurately to your tumour. When the treatment machine is on you will not feel or see the radiation, you will only hear a buzzing noise. You will be in the treatment room for approximately 30 minutes for each treatment. Your treatment appointments will be scheduled Monday to Friday. In dose arms 2 and 3 you may have a day or two break between each treatment

Outcomes
Primary outcome [1] 320011 0
Maximum tolerated dose (MTD) of SABR assessed using a bayesian data augmentation dose finding with the continual reassessment method (DA-CRM). MTD is determined by the occurrence of a dose limiting toxicity (DLT) (as defined by CTCAE criteria) up to 12 months after the first dose of radiotherapy.

A DLT is defined as:
- Any grade 4-5 acute toxicity occurring during or <90 days post completion of RT, or,
- Any grade 3-5 late toxicity occurring > 90 days post completion of radiotherapy and up to 12 months after the first dose of radiotherapy.
Timepoint [1] 320011 0
Toxicity will be assessed weekly throughout treatment and at 6 weeks, 3, 6 and 12 months following treatment completion via face-to face appointments with the treatment doctor. Patients will be instructed to notify the treatment doctor if any side effects occur between scheduled appointments. Side effects may occur in the surrounding thoracic organs such as lung, oesophagus, heart or blood vessels.
Secondary outcome [1] 370221 0
To assess the rate of acute, sub acute and chronic toxicity. Side effects may occur in the surrounding thoracic organs such as, but not limited to, lung, oesophagus, heart or blood vessels.
Timepoint [1] 370221 0
Toxicity will be assessed weekly throughout treatment and at 6 weeks, 3, 6, 12, 18, 24 months and yearly for up to 5 years following treatment completion via face-to face appointments with the treatment doctor. Patients will be instructed to notify the treatment doctor if any side effects occur between scheduled appointments.
Secondary outcome [2] 370222 0
Quality of life (QOL) assessed using European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 and the lung cancer-specific module QLQ-LC13.
Timepoint [2] 370222 0
6 weeks, 3, 6, 12, 18, 24 months and yearly for up to 5 years following treatment completion.
Secondary outcome [3] 370223 0
Tumour local and regional control as defined by the absence of progression at the treated sites as assessed on sequential CT imaging by a multidisciplinary group with or without PET confirmation.
Timepoint [3] 370223 0
3, 6, 12, 18, 24 months and yearly for up to 5 years post radiotherapy
Secondary outcome [4] 370224 0
Overall survival as determined by the time from first treatment to death. Notification of death will be via data linkage to medical records.
Timepoint [4] 370224 0
3, 6, 12, 18, 24 months and yearly for up to 5 years post radiotherapy

Statistical methods / analysis
The Bayesian data augmentation continuous reassessment method (DA-CRM) will be used to analyse the accruing and final DLT data. The MTD is defined as the dose for which the median of the posterior probability distribution for the DLT rate is closest to the target rate (25%) and for which the safety criterion is met.

Tumour local and regional control and overall survival will be estimated by the Kaplan-Meier Method.

QOL will be analysed by repeated measures analysis using linear mixed models.
