Patients will be enrolled to take 60mg of cabozantinib, by mouth, once a day, every day, for 12 weeks. If less than three patients have Progression Free Survival (PFS) lasting at least 12 weeks, the study will be terminated.

Patients will take 60mg cabozantinib, by mouth, once daily, every day for 12 weeks. This medication should be taken on an empty stomach. Patients should not eat 2 hours before or 1 hour after taking cabozantinib. Only water is permitted during this 3 hour time frame.

Oral Tablet: Cabozantinib

This study seeks to use Cabozantinib to treat those with Metastatic Colorectal Cancer who have not previously responded to treatment.

This is a phase II clinical trial that seeks to use Cabozantinib to treat those with Metastatic Colorectal Cancer who have not previously responded to treatment. This study is a two stage study that will first measure (up to) 16 patients' progression free survival (PFS). Stage two will, again, measure PFS, but in a population (up to) 28 patients.

Investigating Cabozantinib in Patients With Refractory Metastatic Colorectal Cancer

An Open-Label, Single-Arm, Two-Stage Phase II Study Investigating Cabozantinib in Patients With Refractory Metastatic Colorectal Cancer

A patient is classified as progression-free if s/he is assessed as not having progressive disease (PD) as defined per RECIST 1.1 criteria at either the 12-week assessment or after having at least 11 weeks of treatment for subjects without the 12-week assessment. Censored patients (i.e. those who have not progressed but who are missing a 12-week assessment) are not included in the analysis. Subjects who didn't have the 12-week assessment but who had clinical progression were included and considered to have progressed.

Per Response Evaluation Criteria In Solid Tumors Criteria (RECISTv1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

This has the same outcome measure description as the primary analysis. Per Response Evaluation Criteria In Solid Tumors Criteria (RECISTv1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

Progression-free survival will be defined as the time from administration of the initial dose of cabozantinib to evidence of radiographic progression as defined by RECIST criteria or death from any cause without evidence of disease progression, whichever occurs first.

\*A patient is classified as a responder if s/he is assessed as having complete response or partial response (CR or PR) at the time of any assessment, where CR and PR are defined per RECIST 1.1 criteria.

Overall Survival will be defined as the time from administration of the initial dose of cabozantinib until death from any cause.

This has the same outcome measure description as the OS analysis.

40 of the 44 subjects were in the analysis population. 3 subjects were not included because they didn't have treatment response data, and 1 subject was not included because that subject didn't reach at least week 11 (and didn't have PD).
