Brief Summary:
This trial is investigating the inclusion of avelumab post long-course chemo-radiotherapy in patients with resectable locally advanced rectal cancer. It is hypothesised that this may enhance the pathological and imaging response rates whilst potentially reducing the relapse rates. Participants will receive standard long course chemoradiotherapy (LCCRT) treatment with radiotherapy and 5-fluorouracil (5 FU)/Capecitabine for 6 weeks, this then followed by 4 cycles of Avelumab and then surgical resection. The trial will measure disease response just prior to surgery and participants will be followed up for a minimum of 18 months (from study entry) and up to 42 months.

Drug Information available for: Avelumab

Arm Intervention/treatment
Experimental: Avelumab
Long course chemoradiotherapy (LCCRT) comprised of 50.4 Gy radiotherapy in conjunction with 5FU (225mg/m2/day continuous infusion)/Capecitabine (825 mg/m2 BID on RT days) over 5. 5 weeks, followed by 4 cycles of Avelumab. This is then followed up with surgical resection
Drug: Avelumab
Avelumab 10 mg/Kg every 2 weeks for 4 cycles post LCCRT
Other Name: MSB0010718C

Drug: 5 Fluorouracil
5FU continuous infusion 225mg/m2/day during radiotherapy

Drug: Capecitabine Pill
Can be administered in place of 5FU infusion. Dose = 825 mg/m2 twice a day on each day of radiotherapy

Radiation: Radiotherapy
50.4 Gy in 28 fractions delivered over 5.5 weeks as 5 fractions/week

Procedure: Surgical Resection
Surgical resection of tumour mass post radiotherapy and chemotherapy

Primary Outcome Measures :
  1. Pathological Response rate [ Time Frame: At time of resection i.e.16 -18 weeks post commencement of treatment ]
    To investigate the role of PD-L1 blockade for rectal cancer following neoadjuvant LCCRT, prior to definitive surgical resection, in terms pathological response rates. Assessed by tumour regression grade in resected rectal cancers post LCCRT at the time of definitive surgery: according to Ryan et al

Secondary Outcome Measures :
  1. Response as per structural imaging [ Time Frame: At 8 weeks post LCCRT ]
    Describe radiological response rate based on Pelvic MRI post PD-L1 blockade as per RECIST 1.1

  2. Overall FDG PET response [ Time Frame: At 8 weeks post LCCRT ]
    Describe FDG-PET response rate post PDL1 blockade as per PERCIST

  3. Define toxicity during administration of PDL1 inhibitor and post-surgery [ Time Frame: From consent until 4 weeks post surgery ]
    Worst grade AE's and SAE's CTCAE version 4.03

  4. Determine rate of downstaging [ Time Frame: At time of surgical resection ]
    Patients will be considered downstaged if the pathologic T or N stage at surgery assessment is lower than the initial radiological stage.
