Brief Summary
HALT is a phase II, randomised multi-centre study with integrated seamless continuation to phase III trial following acceptable safety and feasibility assessment. HALT aims to recruit 110 patients with mutation positive advanced NSCLC with oligoprogressive disease (OPD) following initial response to a Tyrosine Kinase Inhibitor (TKI).

Outcome Measures
Primary Outcomes (1)
Progression free survival
The primary outcome measure is progression free survival defined as the time from randomisation to the first of one of the following events or death from any cause: * Clinically symptomatic progression requiring palliative tumour-specific oncological intervention (e.g. change in systemic therapy or localised non-SBRT radiotherapy) as determined by the treating physician. * New or existing intra-cranial lesions not amenable to radical surgery or Stereotactic radiosurgery (SRS). * Development of new extra-cranial lesions or progression of existing extra-cranial lesions not meeting the criteria for * SBRT treatment (e.g. size \>7cm) * Development of \>5 new or progressing extra-cranial lesion at any one point in time (i.e. widespread progression)
Time from randomisation to the first of one of the above events or death. Assessed 8 weeks post-randomisation and 3-monthly thereafter (up to 24 months)
Secondary Outcomes (9)
Time to next line of systemic therapy or palliative care
Time from randomisation to change in therapy or referral to palliative care due to clinical progression as determined by the treating physician, or death. Assessed 3-monthly until progression and 6-monthly thereafter (up to 24 months).
Overall survival
Time from randomisation until death from any cause. Assessed up to 24 months.
Patterns of disease progression identified from CT scans to further document natural history of oncogene-addicted NSCLC
Assessed 3-monthly up to 24 months.
Radiotherapy toxicities (acute events)
Baseline, 8 weeks and 3-monthly intervals during follow-up (a minimum of 6 months).
Radiotherapy toxicities (late events)
Baseline, 8 weeks and 3-monthly intervals during follow-up (a minimum of 6 months).
- +4 more secondary outcomes
Study Arms (2)
SBRT and continued TKI therapy
EXPERIMENTALPatients will continue to receive background TKI treatment as prior to trial entry. Simultaneous administration (SBRT \& TKI) or break in TKI during SBRT will be by centre preference and determined prior to commencing recruitment. Repeat SBRT will be permissible upon development of subsequent OPD lesions dependent on SBRT suitability and total progression lesion number at any one point remaining ≤ 5.
Continued TKI therapy alone
ACTIVE COMPARATORContinuation on the same background TKI treatment as prior to trial entry

Eligibility Criteria
You may qualify if:
- Male or female, ≥ 16 years of age
- Established histological diagnosis of advanced NSCLC, not suitable for radical treatment, with defined actionable mutation receiving targeted TKI therapy
- Clinical and/or radiologically confirmed response to TKI therapy (assessed locally usually 2-3 months post commencing TKI)
- Confirmed OPD defined as ≤ 5 extracranial sites of progressive disease. All sites must be visible, imaging defined targets and suitable for treatment with SBRT as determined by the virtual multi-disciplinary team (MDT) and in accordance with the HALT Radiotherapy planning and delivery guidance document.
- Adequate baseline organ function to allow SBRT to all relevant targets
- Predicted life expectancy ≥ 6 months
- Karnofsky Index ≥ 60% and ECOG 0-2
- Provision of written informed consent
You may not qualify if:
- \> 5 extracranial sites of progressive disease
- Progressing or newly diagnosed brain metastases identified at the time of trial entry, not amenable to radical surgery or SRS. Previously treated brain metastases (i.e palliative radiotherapy or systemic therapy) which have remained clinically and radiologically stable for ≥ 6 months are permissible.
- Prior radiotherapy near the oligoprogressive lesion precluding ablative SBRT. Suitability of lesions for ablative SBRT as part of the trial defined in section 4.1 of this document and will be determined by the HALT virtual MDT
- Co-morbidities considered clinically precluding the safe use of SBRT (as detailed in the HALT radiotherapy planning and delivery guidelines).
- Any psychological, sociological or geographical issue potentially hampering compliance with the study
- Pregnancy
