Scientific titleA phase I/II trial of isotoxic accelerated radiotherapy in the treatment of patients with non-small cell lung cancer
Study acronymI-START
Study hypothesisThe 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.

Phase I will establish the maximum tolerated dose (MTD) that may be safely delivered to the oesophagus in patients where the oesophagus lies within the radiotherapy high dose region. This will establish the maximum dose to the oesophagus for phase II.

Phase II will establish whether this novel radiotherapy regimen is tolerable, safe and sufficiently active in eligible patients to justify its inclusion as an experimental arm in future randomised phase III trials.
Ethics approval(s)First MREC, 15/09/2010, ref: 10/MRE09/n29
ConditionTopic: National Cancer Research Network; Subtopic: Lung Cancer; Disease: Lung (non-small cell)
InterventionPhase I will have two groups, each with 6 to 12 particpantss who will be treated at each of up to 4 dose levels until the MTD recommended Phase II dose is identified.

49 patients need to be recruited into Phase II, or which 39 should be toxicity-free at three months for evidence to proceed (base on a Flemming 1 stage design)

Radiotherapy, between 58Gy and 65Gy delivered in 20 fractions; Follow Up Length: 24 month(s); Study Entry : Registration only
Intervention typeOther
Primary outcome measureGrade 3 or 4 toxicities; Timepoint(s): occuring up to three months after radiotherapy
Secondary outcome measures1. Dose Limiting Toxicity; Timepoint(s): occuring up to six months after radiotherapy (RT)
2. Estabilsh Maximum Tolerated Dose to the oesophagus; Timepoint(s): acute grade 3 or 4 toxicity occuring up to two months after radiotherapy
3. Local control; Timepoint(s): to the date of first clinical evidence of progressive disease at the primary site, or death
4. Overall Survival; Timepoint(s): date of entry to date of death
5. Tumour response; Timepoint(s): assessed using Response Evaluation Criteria In Solid Tumors (RECIST) at 2 months post RT
Overall study start date01/03/2011
Overall study end date30/04/2016
