Scientific title

Phase III randomised controlled trial Comparing Alternative REgimens for escalating treatment of intermediate and high-risk oropharyngeal cancer


CompARE Trial

Study hypothesis

Pragmatic phase III open-label randomised controlled trial using an efficient, adaptive, multi-arm multi-stage (MAMS) design, with an integrated qualitative recruitment investigation aiming to optimise recruitment and consenting, to determine the optimum treatment of intermediate and high-risk OPC with the aim of improving survival outcomes without significantly worsening toxicity, Quality of Life (QoL) or swallowing function, compared to the current standard treatment of chemoradiotherapy.

Topic: Cancer; Subtopic: Head and Neck Cancer; Disease: Head and Neck


1. Arm 1: Control arm, concomitant chemoradiotherapy, 3-weekly cisplatin 100mg/m2 or weekly 40mg/m2 with Intensity Modulated Radiotherapy (IMRT) using 70Gy in 35F +/- neck dissection as indicated by clinical and radiological assessment 3-months post treatment. This is the international gold standard.
2. Arm 2: Induction chemotherapy (3 cycles at 3-weekly intervals: Docetaxel 75mg/m2 + Cisplatin 80mg/m2 + 5-Fluorouracil (5-FU) 800mg/m2/day, daily for 4 days), followed by Arm 1.
3. Arm 3: Dose-escalated chemoradiotherapy using intensity modulated radiotherapy (IMRT) 64Gy in 25F + Cisplatin 100mg/m2 day 1 of week 1 and of week 5 or weekly 40mg/m2 (neck dissection as indicated by clinical and radiological assessment at 3-months post-treatment).
4. Arm 4: Resection of primary + selective neck dissection followed by chemoradiotherapy. For T1 & T2 primary tumour, resection must be transoral. For T3 & T4 primary tumour, resection preferably transoral if possible otherwise by open surgery.
Follow Up Length: 24 month(s); Study Entry : Registration and One or More Randomisations

Phase III

Drug names

Primary outcome measures

1. Definitive (efficacy) endpoint: Overall Survival (OS) - Interval in whole days between the date of randomisation and the date of death from any cause
2. Interim outcome measure (activity stages): Disease Free Survival (DFS) - Interval between the date of randomisation and the date of death or the 1st documented relapse

Secondary outcome measures

1. Total number of acute (<3 months post-treatment) and late (up to 2 years) severe (grade 3-5) toxicity events at 2 years post randomisation, measured by Common Terminology Criteria for Adverse Events (CTCAE) version 4.0
2. Overall and head and neck specific QoL at 2 years post randomisation, using the European Organisation for Research and Treatment of Cancer (EORTC) C30 and H&N35 Questionnaires
3. Swallowing outcomes using M.D. Anderson Dysphagia Inventory (MDADI) Questionnaire at 24 months and percutaneous endoscopic gastrostomy (PEG) utilisation rates at 1 year
4. Cost effectiveness using EuroQol Group (EQ-5D), patient diaries and primary and secondary resource utilisation data
5. Surgical complication rates in each arm
