Brief Summary

The Primary Phase I objectives are to determine the recommended phase II dose for the capecitabine and aflibercept doublet combination; and to describe any dose limiting and non-dose limiting toxicities. The Phase II Primary objective is to determine progression free survival associated with this regimen. The Phase II secondary objectives are to determine response rate associated with this regimen; to determine overall survival associated with this regimen; and to explore any correlation of clinical outcome with baseline and on treatment changes in blood-based angiogenesis biomarkers. This open-label, non-randomized phase I/II trial is designed to assess the safety, tolerability and RPTD of capecitabine plus aflibercept in adult subjects with metastatic colorectal cancer.

Outcome Measures

Primary Outcomes (3)

• Recommended Phase II Dose (RPTD) for the Capecitabine and Aflibercept Doublet Combination

  Phase 1 of this study will be the dose escalation component to determine safety and the Recommended Phase II dose (RPTD) for the capecitabine plus aflibercept combination. Cohort 1 will receive 850mg/m2 capecitabine and 6mg/kg aflibercept. If less than 2 of 6 patients experience a dose limiting toxicity in Cohort 1, then the next patients will be enrolled in Cohort 2 at 1000mg/m2 capecitabine and 6mg/kg aflibercept. RPTD is determined by the number of dose limiting toxicities (Primary obj 2 for Phase I).

  RPTD for the study will be determined at the completion of Phase I; up to 1 year.

• Number of Dose-Limiting Toxicities (Phase 1)

  Number of patients experiencing a dose-limiting toxicity in each cohort. A dose-limiting toxicity is defined as Grade 4 neutropenia, thrombocytopenia or anemia or grade 3 neutropenia or thrombocytopenia lasting over 7 days Grade 3 thrombocytopenia associated with bleeding Febrile Neutropenia Nausea/Vomiting or Diarrhea ≥ grade 3 and lasting ≥ 4 days despite adequate supportive measures Grade ≥ 3 Bilirubin, ALT or AST \> 7 days Other non-hematologic toxicity ≥ grade 3 excluding alopecia, anorexia, fatigue, hypertension, isolated lab abnormalities (not clinically significant) and/ rare, idiosyncratic reactions to any of the study drugs. Anorexia, fatigue and hypertension will be considered as DLT only if they reach grade 4 or are considered unmanageable Treatment delay of ≥ 14 days for cycle 2 due to unresolved toxicity Treatment-related death or clinically significant,treatment-related hospitalization

  28 days

• Median Progression Free Survival (PFS)

  Time in months from the start of study treatment to the date of first progression (PD) according to the RECIST criteria, or death due to any cause. Per RECIST criteria, a PD is indicated when there is at least a 20% increase in the sum of the longest diameters from target lesions relative to the smallest sum recorded since treatment is initiated. Median PFS was estimated using a Kaplan-Meier curve, and is the time at which 50% of patients remain alive without disease progression.

  approximately 5 months

Secondary Outcomes (2)

• Response Rate

  approximately every 9 weeks and/or restaging, through study completion

• Median Survival

  Subjects will be followed until death which is estimated to be on average 6 months - 1 year after coming off protocol therapy

Study Arms (2)

Phase 1: Capecitabine and Aflibercept

EXPERIMENTAL

A standard 3+3 dose escalation format will be used. Capecitabine will start at 850mg/m2 to be given on days 1-14 and off days 15-21. If tolerated, the dose will then be escalated to 1000mg/m2 for the next cohort, given on the same schedule. The dose of aflibercept will be held constant at 6 mg/kg, given intravenously every 3 weeks.

Drug: Capecitabine and aflibercept

Phase 2: Capecitabine and Aflibercept

EXPERIMENTAL

Once the RPTD of the doublet combination has been identified, an additional 50 subjects with metastatic colorectal cancer will be added to a single, Phase 2 arm

Drug: Capecitabine and aflibercept

Interventions

Capecitabine and aflibercept DRUG

Capecitabine given on days 1-14 and off days 15-21. Dose: Phase 1 cohort 1 850mg/m2 Phase 1 cohort 2 1000mg/m2, Phase 2 RPTD. Aflibercept will be held constant at 6 mg/kg, given intravenously every 3 weeks. Both agents will be administered on a 21-day cycle.

Phase 1: Capecitabine and Aflibercept; Phase 2: Capecitabine and Aflibercept

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• For the phase I portion, patients must have histologically and/or cytologically confirmed malignant solid tumor that is refractory to standard therapies.
• For the phase II portion, patients must have histologically and/or cytologically confirmed metastatic colorectal carcinoma that has progressed on, is intolerant of, or is inappropriate for all standard therapies. Subjects must have been treated with a fluoropyrimidine (e.g., 5-fluorouracil or capecitabine), oxaliplatin, irinotecan and bevacizumab or have contraindication to such treatment. Prior epithelial growth factor receptor (EGFR)-targeting agent (or contraindication to these drugs) is required for subjects with K-Ras wildtype tumors
• Measurable disease by RECIST 1.1 criteria (see Appendix 1). Previously irradiated sites can be included if there is documented progression of disease in that site.
• Age 18 years and older.
• KPS \> 70% (see Appendix 2)
• Life expectancy \> 3 months.
• Adequate organ and marrow function as defined below:
• Absolute neutrophil count \> 1.5 x 109/L
• Platelet count \> 100 x 109/L
• Hemoglobin \> 9 g/dl
• Total bilirubin \< 1.5 x ULN
• AST (SGOT)/ALT (SGPT) \< 2.5 x ULN (or \<5 x ULN if liver metastases)
• Creatinine clearance ≥50 mls/min by Cockcroft-Gault
• Urine Protein/Creatinine ratio \< 1 (or protein \< 1+ on urinalysis or 24hour urine protein \< 1gram/24 hours)
• Previous radiotherapy for palliation of recurrent disease is allowed if \>4 weeks have elapsed since completion of therapy.

You may not qualify if:

• Patients currently receiving anticancer therapies or who have received anticancer therapies within 4 weeks from day 1 of study drug (including investigational agents, chemotherapy, radiation therapy, antibody based therapy, etc.)
• History of severe hypersensitivity reactions/anaphylaxis attributed to humanized and/or chimeric monoclonal antibodies or other such proteins.
• History of abdominal fistula or gastrointestinal perforation at any point within 6 months prior to day 1 of study drug, unless surgically repaired.
• Active peptic ulcer disease, inflammatory bowel disease (e.g. ulcerative colitis, Crohn's disease), diverticular disease or other gastrointestinal conditions with increased risk of perforation or gastrointestinal bleeding.
• Active bleeding diathesis or history of any major bleeding, CNS bleeding, or significant hemoptysis within 6 months of enrollment.
• History of arterial thromboembolic events or symptomatic pulmonary embolism within 6 months of study enrollment.
• Poorly controlled hypertension \[defined as systolic blood pressure (SBP of \>150 mmHg or diastolic blood pressure (DBP) of \>90 mmHg\]
• Patients who have had a major surgery or significant traumatic injury within 4 weeks from day 1 of study drug.
• History of active brain metastases or carcinomatous meningitis (treated metastases are permitted, provided the patient is asymptomatic and off steroids for 28 days).
• 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. 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).
• Any active infection, intercurrent illness, severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the investigator would make the patient inappropriate for entry into this study.
