Inclusion Criteria: Age ≥ 18 years on day of signing informed consent Signed and dated informed consent, and willing and able to comply with protocol requirements WHO/ECOG Performance Status (PS) 0-1 Diagnosis of rectal adenocarcinoma Candidate for sphincter-sparing surgical resection prior to neoadjuvant therapy according to the primary surgeon, i.e. no patient will be included for whom surgeon indicates need for abdomino-perineal resection (APR) at baseline. Clinical staging is based on the combination of the following assessments: Physical examination by the primary surgeon CT scan of the chest/abdomen Pelvic MRI Rigid rectoscopy / endoscopic ultrasound (ERUS). Both examinations (i.e. MRI and ERUS) are mandatory. The tumor has to fulfill the following criteria: No symptomatic bowel obstruction Locally advanced rectal and rectosigmoid cancer, i.e. lower border of tumor > 5 cm and < 16 cm from anal verge as determined by rigid rectoscopy MRI criteria: Lower border of tumor below a line defined by promontorium and symphysis, regardless of the criterion "< 16 cm from anal verge as determined by rigid rectoscopy". No evidence that tumor is adjacent to (defined as within 2 mm of) the mesorectal fascia on MRI (i.e. CRM > 2 mm) Only T3-tumors are included, i.e infiltration into perirectal fat < 10 mm provided CRM > 2 mm Note: MRI criteria are used for the definition of T3 tumor (i.e. exclusion of T2 and T4 situation). Hematological status: Neutrophils (ANC) ≥ 2 x 10^9/L Platelets ≥ 100 x 10^9/L Hemoglobin ≥ 9 g/dL (previous transfusion of packed blood cells allowed) Adequate renal function: Serum creatinine level ≤ 1.5 x upper limit normal (ULN) or ≤ 1.5 mg/dl Creatinine clearance ≥ 30 ml/min Adequate liver function: Serum bilirubin ≤ 1.5 x upper limit normal (ULN) Alkaline phosphatase < 3 x ULN AST and ALT < 3 x ULN Proteinuria < 2+ (dipstick urinalysis) or ≤ 1 g/24hour or ≤ 500mg/dl Regular follow-up feasible For female patients of childbearing potential, negative pregnancy test within 1 week (7 Days) prior of starting study treatment Female patients of childbearing potential (i.e. did not undergo surgical sterilization - hysterectomy, bilateral tubal ligation, or bilateral oophorectomy - and is not post-menopausal for at least 24 consecutive months) must commit to using high effective and appropriate methods of contraception until at least 6 months after the end of study treatment such as combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation, progestogen-only hormonal contraception associated with inhibition of ovulation, intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, vasectomized partner, sexual abstinence. If an oral contraception is used, a barrier method of contraception (e.g. male condom, female condom, cervical cap, diaphragm, contraceptive sponge) has to be applied additionally Fertile male patients with a partner of childbearing potential must commit to using high effective and appropriate methods of contraception (details see above) until at least 9 months after the end of study treatment. Exclusion Criteria: Distant metastases (CT scans of thorax and abdomen are mandatory) cT2 and cT4 tumors (defined by MRI criteria) Exclusion of potentially compromised CRM as defined by MRI criteria (i.e. > 2 mm distance from CRM) Prior antineoplastic therapy for rectal cancer History or evidence upon physical examination of CNS metastasis Uncontrolled hypercalcemia Pre-existing permanent neuropathy (NCI-CTCAE grade ≥ 2) Uncontrolled hypertension (defined as systolic blood pressure > 150 mmHg and/or diastolic blood pressure > 100 mmHg), or history of hypertensive crisis, or hypertensive encephalopathy Concomitant protocol unplanned antitumor therapy (e.g. chemotherapy, molecular targeted therapy, immunotherapy, radiotherapy) Treatment with any other investigational medicinal product within 28 days prior to study entry Known dihydropyrimidine dehydrogenase (DPD) deficiency Treatment with CYP3A4 inducers unless discontinued > 7 Days prior to randomization Any of the following in 3 months prior to inclusion: Grade 3-4 gastrointestinal bleeding Treatment resistant peptic ulcer disease Erosive esophagitis or gastritis Infectious or inflammatory bowel disease Diverticulitis Any active infection within 2 weeks prior to study inclusion Vaccination with a live, attenuated vaccine within 4 weeks prior to the first administration of the study medication Other concomitant or previous malignancy, except: Adequately treated in-situ carcinoma of the uterine cervix Basal or squamous cell carcinoma of the skin Cancer in complete remission for > 5 years Any other serious and uncontrolled non-malignant disease, major surgery or traumatic injury within the last 28 days prior to study entry Pregnant or breastfeeding women Patients with known allergy to any constituent to study drugs History of myocardial infarction and/or stroke within 6 months prior to randomization, NYHA class III and IV congestive heart failure Severe renal insufficiency (creatinin clearance < 30 ml/min) Bowel obstruction Contra-indication to the assessment by MRI Involvement in the planning and/or conduct of the study (applies to both Sanofi staff and/or staff of Sponsor and study site) Patient who might be dependent on the sponsor, site or the investigator Patient who has been incarcerated or involuntarily institutionalized by court order or by the authorities § 40 Abs. 1 S. 3 Nr. 4 AMG Patients who are unable to consent because they do not understand the nature, significance and implications of the clinical trial and therefore cannot form a rational intention in the light of the facts [§ 40 Abs. 1 S. 3 Nr. 3a AMG].
