Key exclusion criteria
1. Patients with disease outside the pelvis

2. Prior pelvic radiotherapy

3. Participation in another interventional clinical trial within 30 days of registration
(participation in observational studies are permitted)

4. Concurrent anti-cancer treatment

5. Concurrent treatment with a non-permitted drug (Section 8.3.2)

6. Major surgery for any reason within 4 weeks of registration (except defunctioning
stoma creation with the patient having fully recovered from this procedure)

7. Current use of immunosuppressive medication. Except for the following: (a) intranasal,
inhaled, topical steroids, or local steroid injection (e.g., intra-articular
injection); (b). Systemic corticosteroids at physiologic doses = 10 mg/day of
prednisone or equivalent; (c). Steroids as premedication for hypersensitivity
reactions (e.g., CT scan premedication); (d) Short-term administration of systemic
steroids (that is, for allergic reactions or the management of irAEs) is allowed while
on study.

Note: Patients receiving bisphosphonate or denosumab are eligible

8. Active autoimmune disease that might deteriorate when receiving an immunostimulatory
agent. Patients with diabetes type I, vitiligo, psoriasis, or hypo- or hyperthyroid
diseases not requiring immunosuppressive treatment are eligible

9. Active or history of immunodeficiencies

10. Has received prior therapy with an anti-PD1, anti-PDL1, anti-PDL2 or anti-CTLA-4
agents

11. Has clinically significant (that is, active) cardiovascular disease: cerebral vascular
accident / stroke (< 6 months prior to registration), myocardial infarction (< 6
months prior to registration), unstable angina, congestive heart failure (New York
Heart Association Classification Class = II), or serious cardiac arrhythmia requiring
medication.

12. Has an active infection requiring systemic therapy

13. Other severe acute or chronic medical conditions including immune colitis,
inflammatory bowel disease, immune pneumonitis, pulmonary fibrosis or psychiatric
conditions including recent (within the past year) or active suicidal ideation or
behaviour; or laboratory abnormalities that may increase the risk associated with
study participation or study treatment administration or may interfere with the
interpretation of study results and, in the judgment of the investigator, would make
the patient inappropriate for entry into this study

14. Prior malignancies within 3 years of registration (with the exception of non-
melanomatous skin cancer)

15. Prior organ transplantation, including allogeneic stem-cell transplantation

16. A known history of testing positive for HIV or known acquired immunodeficiency

formulations, including known severe hypersensitivity reactions to monoclonal
antibodies (CTCAE v4.03 grade = 3)

19. Is pregnant or lactating

20. Vaccination within 4 weeks of registration and while on trials is prohibited except
for administration of inactivated vaccines

21. Known deficiency of dihydropyrimidine dehydrogenase

Summary
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.
