The primary objective of this open-label phase Ib trial is to determine the maximum tolerated dose and the recommended phase II dose for the combination of PF-03446962 plus regorafenib in patients with metastatic colorectal cancer. The secondary objectives are to describe the safety and tolerablility, and to describe the clinical activity of PF-03446962 plus regorafenib in terms of response rate and progression free survival

Experimental: PF-03446962 plus regorafenib
PF-03446962 will be an investigational formulation supplied by Pfizer . PF-03446962 injection, 10 mg/mL is presented as a sterile solution for IV administration in a formulation consisting of precedented excipients. We will be administering PF-03446962 intravenously at a starting dose of 4.5 mg/kg and escalating to up to 7 mg/kg.
We will be administering regorafenib on-label for the indication of metastatic colorectal cancer. The indicated dose is 160 mg once daily for the first 21 days of a 28 day cycle. We will start at a regorafenib dose of 120 mg in the combination therapy, but may increase to 160 mg during dose escalation.

- Prior regorafenib use with disease progression (expanded cohort only).

- Have had a major surgery or significant traumatic injury within 4 weeks from day 1 of study drug,
- Have not recovered from the side effects of any major surgery (defined as requiring general anesthesia) or
- Are anticipated to require major surgery during the course of the study.
- Patients who have exhibited hypersensitivity reactions to regorafenib and/or a structural compound, biological agent, or formulation (eg sorafenib).
- Grade 3-4 AE associated with prior anti-VEGF therapy. Grade 3 hypertension that was readily managed will be permitted.
- History of grade 3 or higher hypersensitivity reactions/anaphylaxis attributed to humanized and/or chimeric monoclonal antibodies or other such proteins. Hypersensitivity reactions that are clearly related to cetuximab may be permitted at the discretion of the principal investigator.
Patients receiving chronic, systemic treatment with corticosteroids or another immunosuppressive agent with the following exceptions:
- Intermittent steroids (not to exceed 4 mg every day) may be used on an as-needed basis (e.g. treatment for chemotherapy-related nausea, anorexia and fatigue.)
- Patients on physiologic replacement doses of steroids due to adrenal insufficiency for any reason may remain on these medications.

Following antihypertensive medication initiation or adjustment, blood pressure (BP) must be re-assessed three times at approximately 2-minute intervals. At least 24 hours must have elapsed between anti-hypertensive medication initiation or adjustment and BP measurement. These three values should be averaged to obtain the mean diastolic blood pressure and the mean systolic blood pressure. The mean SBP/DBP ratio must be <140/90 mmHg in order for a subject to be eligible for the study.

- Active bleeding diathesis.
- Known endobronchial lesions and/or lesions infiltrating major pulmonary vessels that increase the risk of pulmonary hemorrhage.

- Female patients who are pregnant or breast feeding, or adults of reproductive potential who are not using effective birth control methods. Two acceptable forms of contraceptives must be continued throughout the trial by either sex and for 2 months (60 days) following last dose of either drug. Hormonal contraceptives are not acceptable as a sole method of contraception. (Women of childbearing potential must have a negative serum pregnancy test within 7 days prior to day 1 of study drug).
- Concomitant use of CYP3A4 strong inducers and strong inhibitors. (See Appendix 7).
- Corrected QTc interval > 500 msec. If QTc interval is > 500 msec, then 2 additional ECGs should be obtained over a brief period of time (e.g., within 15-20 minutes) to confirm the abnormality. The average QTc interval will be determined from the 3 ECG tracings by manual evaluation and will be used to determine if the subject will be excluded from the study. The same method of QTc determination must be used throughout the subject's participation in the trial.
- History of Osler-Weber-Rendu syndrome or Hereditary Hemorrhagic Telangiectasia
