Trial overview
Official title: Phase I study of Safety and Pharmacokinetics of pazopanib in combination with Cetuximab and irinotecan in patients with colorectal cancer
Trial description: Subjects will be entered into cohorts of 3 for the dose escalation phase so that the maximum tolerated dose can be determined. 18 additional patients will be recruited once the maximum tolerated dose (MTD) is determined for disease assessment.
Primary purpose:
Treatment
Trial design:
Single Group Assignment
Masking:
None (Open Label)
Allocation:
Not applicable
Primary outcomes:
The safety and tolerability of the maximum tolerated dose defined as a dose regimen where no more than 1 of 6 subjects experiences a dose limiting toxicity.
Timeframe: End of 2009
Secondary outcomes:
pharmacokinetics disease assessment
Timeframe: 2010
Clearance of irinotecan (if data permit) and AUC, Cmax, tmax, and t1/2 of irinotecan and SN-38 after administration of irinotecan plus cetuximab.
Timeframe: 2010
AUC(0-24), Cmax, tmax, and t1/2 of pazopanib when administered with irinotecan and cetuximab
Timeframe: 2010
AUC(0-24), Cmax, and tmax of cetuximab when administered with irinotecan alone
Timeframe: 2010
AUC(0-24), Cmax, and tmax of cetuximab when administered with irinotecan plus pazopanib.
Timeframe: 2010
The ratio of SN-38 AUC(0-24) and irinotecan AUC(0-24) on Cycle 1 Day 1 and on Cycle 2 Day 1.
Timeframe: 2010
Objective response rate (complete response (CR) plus partial response (PR)) will be the primary measure of antitumor activity

- Inclusion criteria:
- Male or female at least 18 years of age.
- Willing and able to sign a written informed consent.
- Is either affiliated to or a beneficiary of a social security category
- Histologically or cytologically confirmed diagnosis of colorectal cancer. Subjects should have metastatic disease which is refractory or relapsed following prior treatment.
- Documented disease progression after prior treatment with 5-FU, oxaliplatin and irinotecan containing regimens.
- Complete recovery from surgical or radiotherapy procedures.

- Adequate renal function as determined by a creatinine clearance greater than 50 mL/minute calculated by the Cockcroft-Gault Formula. Measured creatinine clearance greater than or equal to 50 mL/minute by 24 hour urine collection will be acceptable in lieu of a calculated value.
- Urine Protein Creatinine (UPC) Ratio of ≤ 1 as assessed in a random or spot urine sample.
- Adequate hepatic function determined by total bilirubin within the normal range and aspartate aminotransferase (AST or SGOT) or alanine aminotransferase (ALT or SGPT) less than or equal to 2.5 times the upper limit of normal.
- Prothrombin time (PT), international normalized ratio (INR), and partial thromboplastin time (PTT) less than or equal to 1.2 times the ULN.
- A female subject is eligible to enter and participate in the study if she is: ·Non-childbearing potential (i.e., physiologically incapable of becoming pregnant) including any woman who:
- Has had a hysterectomy, or
- Has had a bilateral oophorectomy (ovariectomy), or
- Has had a bilateral tubal ligation, or
- Is post-menopausal (demonstrate total cessation of menses for greater than or equal to 1 year).
- Childbearing potential, has a negative serum pregnancy test at screening, and agrees to one of the following:
- An intrauterine device with a documented failure rate of less than 1% per year.
- Vasectomized partner who is sterile prior to the subject's entry and is the sole sexual partner for that woman.
- Complete abstinence from sexual intercourse for 14 days before exposure to investigation product, throughout the clinical trial, and for at least 21 days after the last dose of investigational product.
- Double barrier contraception defined as condom with spermicidal jelly, foam, suppository, or film; OR diaphragm with spermicide; OR male condom and diaphragm.
- A male patient with a female partner of childbearing potential is eligible to enter and participate in the study if he uses a barrier method of contraception or abstinence during the study.
- Predicted life expectancy of at least 12 weeks.
- Able to understand and comply with protocol requirements and instructions and intends to complete the study as planned. Exclusion criteria:
- Has participated in any study using an investigational drug during the previous 28 days.
- Has had any major surgery, chemotherapy, investigational agent, or radiotherapy within the last 28 days and/or not recovered from prior therapy.
