Description of intervention(s) / exposure
open label non randomised phase I combination of Tarloxotinib and stereotactic
body radiation in a window of opportunity setting prior to surgery for
advanced HPV negative head and neck cancer.
Cohort A: Four pts will undergo baseline and day 14 oxygen-enhanced magnetic resonance imaging (OE-MRI)
to test logistics of OE-MRI acquisition and University of Manchester analysis (CAMRI).
Cohort B: Four patients will undergo Tarloxotinib monotherapy 150 mg/m2 IV days 1,11 with baseline and day 14 OE-MRI to evaluate safety.
Cohort C: Four patients will undergo the combination of Tarloxotinib 150 mg/m2 IV days 1,11 and SBRT 6 Gy x 3 days 4,6 and 8, with baseline and day 14 OE-MRI.
After surgical resection (day 25 or later), pts from all cohorts will continue with standard care including post-operative radiation therapy (PORT) if appropriate.
Each cohort will recruit sequentially.
Tarloxotinib will be administered at a dose of 150 mg/m2 IV as a 1-hour infusion on Day 1 and Day 11 in Cohort B and Cohort C. Tarloxotinib infusions must be at least 1 hour (60 minutes) in duration.
SBRT will be administered by the Department of Radiation Oncology Auckland City Hospital.

Outcomes
Primary outcome [1] 330231 0
The incidence of treatment related serious adverse events associated with Tarloxotinib and SBRT study protocol resulting in delay to surgery beyond day 39. Adverse events will be assessed using Common Toxicity Criteria for Adverse Events (CTCAE v5). Examples od adverse events which could be relevant include diarrhoea and macula-papular rash.
Timepoint [1] 330231 0
day 39 of study protocol.
Secondary outcome [1] 403738 0
A second objective of the study is to test if there is a significant change in the hypoxic fraction following treatment with Tarloxotinib on it's own or in combination with stereotactic body radiotherapy for human papilloma virus negative head and neck cancer prior to surgery. This will be evaluated using a specialised type of MRI scan, called Oxygen-enhanced MRI which calculates hypoxic fraction. The secondary outcome is change in hypoxic fraction between baseline and day 11 of study protocol.
Timepoint [1] 403738 0
baseline and day 11 of study protocol
Secondary outcome [2] 406144 0
To estimate the proportion of patients with a major pathological response (mPR; less than 10% viable tumour cells at surgery). The pathologists will be reporting the percentage of viable tumour cells in the resected specimen, banded in increments of 10%.
Timepoint [2] 406144 0
date of surgery
Secondary outcome [3] 406146 0
To describe the occurrence of treatment-related adverse events (unplanned delay to surgical resection due to toxicity, post-surgical complications grade 3 or higher using Clavien Dindo scale, and life-threatening arrhythmia). CTCAE v5 will be used to document treatment-related adverse event resulting in unplanned delay to surgery. The medical records will used to document post surgical complications using the Clavien Dindo scale. Patients will be on telemetry during Tarloxotinib infusions until 4 hours post infusion to document life-threatening threatening arrhythmias.
Timepoint [3] 406146 0
up to week 20 of study protocol

Other design features
The study is divided into 3 cohorts which will be described separately.
The primary hypothesis in the Phase I is that tarloxotinib and SBRT will not adversely impact on the ability to proceed with surgery, with no treatment related adverse events (AE) resulting in delay to surgery beyond day 39. Four pts will undergo baseline and day 14 OE-MRI to test logistics of OE-MRI acquisition and analysis (Cohort A). Four pts will undergo Tarloxotinib monotherapy 150 mg/m2 IV days 1,11 with baseline and day 14 OE-MRI (Cohort B). Four pts will undergo the combination of Tarloxotinib 150 mg/m2 IV days 1,11 and SBRT 6 Gy x 3 days 4,6 and 8, with baseline and day 14 OE-MRI (Cohort C). After surgical resection (day 25 or later), pts from all cohorts will continue with standard care including post operative radiotherapy if appropriate.

Type of endpoint/s
Statistical methods / analysis
The primary objective is that tarloxotinib and SBRT will not adversely impact on the ability to proceed with surgery with no treatment related adverse events (AE) resulting in delay to surgery beyond day 39. A descriptive report will be prepared.
Secondary objectives are
1. to estimate the proportion of patients who experience a reduction in tumour hypoxic fraction (measured using OE-MRI) of at least 50%.
2. To estimate the proportion of patients with a major pathological response (mPR; less than 10% viable tumour cells at surgery).
3. To describe the occurrence of treatment-related adverse events (unplanned delay to surgical resection due to toxicity, post-surgical complications grade 3 or higher using Clavien Dindo scale, and life-threatening arrhythmia).
