Plain-language summary
This is a multicenter, single-arm, phase II study of nivolumab in combination with regorafenib in subjects with locally-advanced rectal cancer who are eligible for a curative treatment including pre-operative SCRT and TME(or watch \& wait approach). The study is based on the Simon's two-stage design and a maximum of 60 subjects will be enrolled. In addition to the standard efficacy interim analysis according to the statistical design, a safety interim analysis will be performed on the first 6 subjects who have completed the study treatment to ensure safe continuation of the study investigation.
Eligible subjects will be treated according to the following sequential treatment plan:
* Induction treatment: This consists of treatment with nivolumab (240 mg intravenously, on day 1 and 15) and regorafenib (60 mg/day orally, from day 1 to 14)
* Standard SCRT: This consists of 25 Gy delivered in 5 fractions (from day 22 to 26)
* Consolidation treatment: This consists of treatment with nivolumab (240 mg intravenously, on day 29, 43 and 57) and regorafenib (60 mg/day orally, from day 29 to 49)
* Surgery: Surgical resection will be performed according to the principles of TME (between day 74 and 87, i.e., between 7 to 8 weeks after completion of SCRT). As an alternative to surgery, subjects who achieve cCR can be offered a watch \& wait approach.
* Adjuvant chemotherapy: Administration of adjuvant chemotherapy will be left to the discretion of the treating physician
The study also includes translational procedures (i.e. collection of tumour biopsies, blood samples and stool samples at pre-specified time points) for exploratory molecular and immune contexture analyses. These are mandatory for all study subjects.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Evaluation of the efficacy of the combination of nivolumab and regorafenib when administered before and after standard, pre-operative short-course radiation therapy.
. Adequate haematological function as defined by absolute neutrophil count (ANC) ≥1.5 × 109/L, platelet count ≥100 × 109/L, and haemoglobin ≥9 g/dL
Exclusion criteria
. Any prior or concurrent surgery, chemotherapy, radiotherapy, immunotherapy, biologic or hormonal therapy for rectal cancer. Concurrent use of hormones for noncancer-related conditions (i.e., insulin for diabetes and hormone replacement therapy) is acceptable.
. Any contraindication to pelvic irradiation as evaluated by the investigator
. Prior organ transplantation, including allogeneic stem cell transplantation
. Clinically significant acute or chronic infections including, among others:
. Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent (subjects with diabetes type I, vitiligo, psoriasis, hypo- or hyperthyroid disease not requiring immunosuppressive treatment are eligible)
. Systemic corticosteroids administered as hormone replacement or as immunosuppressants at doses exceeding 10 mg/day of prednisone or equivalent. Other immunosuppressive medications including, but not limited to methotrexate, azathioprine, and TNF-α blockers. Use of immunosuppressive medications for the management of treatment-related AEs or in subjects with contrast allergies is acceptable. A temporary period of steroids is allowed for different indications, at the discretion of the investigator (i.e., chronic obstructive pulmonary disease, radiation, nausea, etc.). Administration of steroids through a route known to result in a minimal systemic exposure \[topical, intranasal, intro-ocular, or inhalation\] is acceptable.
. Known severe hypersensitivity reactions to the investigational treatments, or any excipients or non-investigational medicinal products or concomitant medications
