least 28 days prior to enrolment, except for those who have declined or are not
eligible for COVID-19 vaccination.
5. Patient has recovered to Grade =1 (CTCAE v5.0) from the effects (excluding alopecia)
of any prior therapy for their malignancies.
6. Patient has at least one measurable lesion per RECIST 1.1 criteria by computed
tomography scan or magnetic resonance imaging (non-neoadjuvant cohorts).
7. Wherever possible, patients not scheduled for curative intent resection surgery should
have a fresh tumour biopsy (or have an archival biopsy [obtained within the past 5
years] if obtaining a fresh biopsy is not feasible) at baseline for molecular studies,
and agree to a post-treatment biopsy (at Week 25 or the end of treatment visits), if
feasible. Patients in the SCCHN neoadjuvant cohort must have both a fresh
pre-treatment biopsy and agree to have their resected tumour analysed.
8. Patient is male or female and at least 18 years of age.
9. Patient has a life expectancy of more than 6 months.
10. Patient has an ECOG performance status of 0 or 1.
