A Study to Investigate Biomarker Effects of Pre-Surgical Treatment With DNA Damage Repair (DDR) Agents in Patients With Head and Neck Squamous Cell Carcinoma (HNSCC).
- Conditions
- Head and Neck Squamous Cell Carcinoma
- Interventions
- Registration Number
- NCT03022409
- Lead Sponsor
- AstraZeneca
- Brief Summary
This biomarker study has been designed to assess the effects of different agents in both tumour tissue and peripheral samples to help inform the best combinations of DDR agents with immuno-oncology (IO) therapies. In the first instance 2 DDR agents will be assessed separately as monotherapy. Additional arms may be added later to evaluate other DDR agents and/or DDR and immunotherapy agents in combination or in sequence. The primary objective of the study is to investigate immune activation due to DDR inhibition by assessing tumour and blood samples of patients treated with study investigational agent(s).
- Detailed Description
Patients are dosed for a minimum of nine days with drug. Surgery or biopsy can then take place at any time between Day 10 and Day 21 (depending on when it can be scheduled), but must occur with 24 hrs following three consecutive treatment days. During the treatment period, safety assessments must be completed at least weekly.
Follow-up will be completed after surgical resection or biopsy has been completed and can be part of standard post-surgery follow-up. If this follow-up visit occurs prior to 30 days after the final dose, a further visit or telephone call must be conducted to assess that any toxicity has resolved and to check for late toxicity.

Patients who are suitable for radical chemoradiation without surgery are eligible if they are willing to undergo an on-treatment biopsy (FNA samples are not acceptable, specimens must be core or surgical biopsy).
- Females must be using adequate contraceptive measures, must not be breast feeding and must have a negative pregnancy test prior to start of dosing if of child-bearing potential or must have evidence of non-child-bearing potential
- For the duration of the study and for 6 months after the last study drug administration, sexually active male patients must be willing to use barrier contraception i.e., condoms with all sexual partners
- No previous systemic cancer treatment or radiotherapy for the current malignancy
- Provision of genetics research informed consent

Group Intervention Description Olaparib Olaparib Olaparib (300 mg) tablets administered orally twice daily continuously for a minimum of 9 days and a maximum of 21 days. AZD6738 Ceralasertib AZD6738 (160 mg) tablet twice daily continuous dosing for a minimum of 9 days and a maximum of 21 days.
- Primary Outcome Measures
Name Time Method Conversion of an immunologically based 25-gene signature from a prognostically unfavourable state to a prognostically favourable state. From baseline through Day 31 (Follow up) To investigate prognosis-correlated immune activation due to DDR inhibition by monitoring the induction of immunologically relevant genes in tumours of patients treated with study investigational agent(s)
- Secondary Outcome Measures
Name Time Method Transition from a low tumour infiltrating leukocyte (TIL) state (poor prognosis) to a high TIL state (favourable prognosis) shown by TIL enumeration and an increase in CD8+ T-cells From baseline through Day 31 (Follow up) To investigate the prevalence and localization of TILs associated with prognosis.
Transition from a low TIL infiltrative state (poor prognosis) to a high TIL infiltrative state (favourable prognosis) shown by TIL enumeration and an increase in CD3+ T-cells From baseline through Day 31 (Follow up) To investigate the prevalence and localization of tumour infiltrating leukocytes (TILs) associated with prognosis.
Vital signs From screening until Day 15 (+ 2 days) Assessment of the safety for each DDR agent in terms of the Vital signs
Clinical chemistry/haematology From screening until Day 15 (+ 2 days) Assessment of the safety for each DDR agent in terms of the clinical chemistry / haematology assessments
Number of patients with abnormal findings in Electrocardiograms (ECG) At screening and Day 1 Assessment of the safety for each DDR agent in terms of the ECG changes. A 12-lead ECG will be performed in triplicate at screening and at a time convenient during the visits (single ECG only required at subsequent visits).
