Inclusion Criteria

• Histologically (archival tissue) confirmed adenocarcinoma of the rectum that begins within 12 cm of the anal verge as determined by sigmoidoscopy and/or colonoscopy with no evidence of distant metastasis.
• Locally advanced rectal cancer determined by any of the following features: 1.) Fixed or immobile tumor on physical exam and/or; 2.) T3 disease with invasion through the muscularis propria as defined by transrectal ultrasound, CT or MRI; 3.) T4 disease with invasion of adjacent structures such as pelvic sidewall, sacrum, pelvis, bladder and/or prostate as determined appropriate imaging modalities such as ultrasound, CT or MRI; 4.) Any T with + N on CT scan/MRI or transrectal ultrasound.
• Age equal to or greater than 18 years
• Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1.
• Adequate bone marrow, liver and renal function.
• Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of treatment.
• Women of childbearing potential and men must agree to use adequate contraception (barrier method of birth control) prior to study entry and for the duration of study participation. Men should use adequate birth control for at least 3 months after the last administration of lenvatinib.
• Ability to understand and the willingness to sign a written informed consent. A signed informed consent must be obtained prior to any study specific procedures.

• Previous pelvic irradiation therapy.
• Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy.
• Uncontrolled hypertension defined as systolic blood pressure > 150 mmHg or diastolic pressure > 90 mmHg, despite optimal medical management.
• Known human immunodeficiency virus (HIV) infection or chronic hepatitis B or C.

Arm && Interventions

Group	Intervention	Description
Pre-Surgery Chemotherapy/Radiotherapy	External Radiation Therapy (XRT)	Pre-surgery chemotherapy and external radiation therapy. Dose escalation of Lenvatinib; fixed dose Capecitabine; Radiotherapy. Lenvatinib and capecitabine will be started on day 1 with radiation and will be discontinued on the last day of radiation. Surgical resection should occur between 6 - 10 weeks after the participant completes preoperative lenvatinib, capecitabine, and radiation therapy. Postoperative chemotherapy after surgery will be given at investigator's discretion.
Pre-Surgery Chemotherapy/Radiotherapy	Capecitabine	Pre-surgery chemotherapy and external radiation therapy. Dose escalation of Lenvatinib; fixed dose Capecitabine; Radiotherapy. Lenvatinib and capecitabine will be started on day 1 with radiation and will be discontinued on the last day of radiation. Surgical resection should occur between 6 - 10 weeks after the participant completes preoperative lenvatinib, capecitabine, and radiation therapy. Postoperative chemotherapy after surgery will be given at investigator's discretion.
Pre-Surgery Chemotherapy/Radiotherapy	Lenvatinib	Pre-surgery chemotherapy and external radiation therapy. Dose escalation of Lenvatinib; fixed dose Capecitabine; Radiotherapy. Lenvatinib and capecitabine will be started on day 1 with radiation and will be discontinued on the last day of radiation. Surgical resection should occur between 6 - 10 weeks after the participant completes preoperative lenvatinib, capecitabine, and radiation therapy. Postoperative chemotherapy after surgery will be given at investigator's discretion.

Primary Outcome Measures

Name	Time	Method
Maximum Tolerated Dose (MTD)	Up to 6 months	MTD of lenvatinib used in combination with capecitabine and external beam radiation as neoadjuvant therapy for patients with locally advanced rectal carcinoma. The MTD of lenvatinib will be defined as the highest dose level at which no more than 1 out of 6 participants experiences dose-limiting toxicity (DLT). DLT: Any of the hematology or non-hematologic toxicities noted in Table 3 of the protocol, considered to be at least possibly related to lenvatinib and/or capecitabine.

Secondary Outcome Measures

Name	Time	Method
Rate of Pathologic Response	Up to 36 months	Pathologic response rate after pre-operative therapy and surgery. Pathologic Complete Response (pCR) will be defined as pathologic proof of a complete response based on histologic evaluation of the resected specimen.
Occurrence of Treatment Related Adverse Events	Up to 36 months	To further define safety profile of the combination. Adverse events will be graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 4.0.
