Brief Summary:

This is a prospective non-randomised Phase I/II study with patients recruited to escalated dose cohorts. Escalated dose to the iGTV (internal gross tumour volume), with 60 Gy to the conventional PTV (planning target volume), will be delivered to successive cohorts of participants (6-12 participants/cohort) until the maximum tolerated oesophageal dose is determined. The minimum dose will be 60 Gy delivered via intensity modulated radiation therapy (IMRT) or volume modulated arc therapy (VMAT), planned on an Average Intensity Projection (AVIP) dataset.

Standard of care chemotherapy.

There will be two treatment arms; one with patients who are planned to receive neo-adjuvant or no chemotherapy, and the other with patients who are planned to receive concurrent chemotherapy.


Condition or disease Intervention/treatment Phase
Non-Small Cell Lung Cancer Radiation: Radiation Phase 1 Phase 2

Detailed Description:

This is a prospective non-randomised Phase I/II cohort study; please see above for Radiation Therapy and Chemotherapy treatment details

Each cohort will require a minimum of 6 and a maximum of 12 patients. Once 6 patients have been treated in a cohort a two-month break is taken before toxicity is analysed.

  • If 2 or fewer patients experience a grade ≥3 toxicity, the next cohort will be enrolled and will receive an escalated dose (an additional +5 Gy at each escalation up to a maximum of 75 Gy)
  • If 3 of the 6 patients experience a grade ≥3 toxicity, a further 6 patients will be recruited into that dose level
  • If 4 or more patients experience a grade ≥3 toxicity then the MTD is fixed at the dose level of the previous cohort

If the cohort is extended to 12 patients, the following rules apply:

  • If 4 or fewer patients experience a grade ≥3 toxicity, the next cohort will be enrolled and will receive an escalated dose.
  • If 5 of the 12 patients experience a grade ≥3 toxicity, then the MTD is fixed at that dose level and recruitment continues up to a total of 24 patients at that dose level.
  • If 6 or more patients experience a grade ≥3 toxicity, then the MTD is fixed at the dose level of the previous cohort.

Once the maximum dose cohort is established, patients will continue to be recruited at that dose level up to a total of 24 patients.

There will be two treatment arms; one with patients who are planned to receive neo-adjuvant or no chemotherapy, and th eother with patients who are planned to receive concurrent chemotherapy.

The concurrent and neo-adjuvant /no chemotherapy arms will then be escalated independently of each other.

For each arm the following number of patients will be required:

  • Minimum number (if maximum dose level reached) = 36 (6 at 65 Gy, 6 at 70 Gy and 24 at 75 Gy)
  • Maximum number (if maximum dose level reached) = 48 (12 at 65 Gy, 12 at 70 Gy and 24 at 75 Gy) A maximum of 48 patients are required to complete each arm (neo-adjuvant or none /concurrent chemotherapy) of the trial.

Acute toxicity will be assessed weekly during treatment and at 2, 4 and 8 weeks post-treatment Late toxicities will be assessed at 3, 6, 9, 12, 18 and 24 months post-treatment and annually thereafter until disease relapse / patient withdrawal / patient death.

Arm Intervention/treatment
Trial Cohort Description

Escalated dose of min 65Gy to the iGTV, with 60Gy to PTV delivered to successive cohorts of patients(pts) until the MTD oesophageal dose is determined. Toxicity will be analysed 2 months post 6pts treated in a cohort.

If: ≤2pts have ≥G3 toxicity, next cohort will be enrolled & receive escalated dose (an additional +5Gy at each escalation upto max 75Gy)/3 of 6pts have ≥G3 toxicity, a further 6pts will be recruited into that dose level/≥4pts have ≥G3 toxicity, the MTD is fixed at dose level of previous cohort

Cohort is extended to 12pts:

If: ≤4pts have ≥G3 toxicity, next cohort will be enrolled & receive escalated dose/5 of 12pts have ≥G3 toxicity, the MTD is fixed at that dose level & recruitment continues up to 24pts/≥6pts have ≥G3 toxicity, the MTD is fixed at the dose level of previous cohort.

Once the max dose cohort is established, recruiting will continue at that dose until 24pts. Concurrent & neo-adjuvant/no chemotherapy arms will be escalated independently of each other

Radiation: Radiation
Escalated dose of minimum 65Gy to the iGTV, with 60 Gy to PTV.




Primary Outcome Measures :
  1. To assess the safe delivery of an achievable level of dose escalation in a dose escalated and intensified RT regime delivered via VMAT/IMRT and focused on the GTV by the proportion of grade ≥3 toxicities determined to be related to RT [ Time Frame: 4 years 3 months ]

Secondary Outcome Measures :
  1. To compare grade ≥3 toxicity 3, 6, 9, 12, 18 and 24 months, post-treatment, graded by NCI-CTCAE Version 4 (V4) [ Time Frame: 2 years post treatment ]
  2. To estimate the rate of overall survival; death from any cause is considered an event [ Time Frame: 8 years ]
  3. To estimate the rate of disease-free survival. All disease recurrences will be recorded. In disease-free survival, any tumour recurrence, development of distant metastases or death is considered an event. [ Time Frame: 8 years ]
  4. To estimate the time to local failure (failure defined by RECIST V1.1 ) [ Time Frame: 8 years ]
  5. To evaluate tumour response at 6, 12 and 24 months (response measured by RECIST V1.1) [ Time Frame: 2 years ]
  6. The estimate the time to distant metastases as assessed by imaging or biopsy [ Time Frame: 8 years ]
  7. To assess Quality of life according to the EORTC QLQ-C30 and EORTC QLQ-LC13 [ Time Frame: 8 years ]
  8. To assess the MTD to the oesophagus. The MTD is defined as the highest dose that does not cause unacceptable toxicities. Toxicities of interest are any CTCAE V4 grade ≥3 oesophageal toxicity determined to be related to radiation therapy. [ Time Frame: 5 years ]
  9. The change in pulmonary function post-treatment will be analysed by calculating the differences in measurements from baseline to the 1-year follow-up [ Time Frame: 1 year ]
