Clinical Trial Summary

This randomized (2:1), multi-center, placebo-controlled, phase II efficacy study is designed to compare PFS between regorafenib + FOLFIRI chemotherapy (ARM A) versus placebo + FOLFIRI (ARM B) in patients with mCRC previously treated with a FOLFOX regimen.

Description:

This randomized (2:1 ratio), multi-center, placebo-controlled, phase II efficacy study is designed to compare progression-free survival (PFS) between regorafenib + FOLFIRI (5-fluorouracil + leucovorin + irinotecan [ARM A] versus placebo + FOLFIRI [ARM B]) in patients with metastatic colorectal carcinoma (mCRC) previously treated with a FOLFOX (5-fluorouracil + leucovorin + oxaliplatin) regimen. Secondary objectives include objective response (OR) rates, disease control (DC) rates, and overall survival (OS). A pharmacokinetic (PK) evaluation of irinotecan will be conducted in a subset of patients at selected sites. This trial also incorporates a number of exploratory analyses designed to evaluate potential correlations between blood and tissue biomarkers and clinical benefit.

Eligibility

Inclusion Criteria

Subject must meet all of the inclusion criteria to participate in this study:

1. Age =18 years of age (no upper age limit)

2. Histological or cytological documentation of adenocarcinoma of the colon or rectum

3. Archived, paraffin-embedded tissue block (primary or metastatic) available for genomic studies required

4. Metastatic disease not amenable to surgical resection with curative intent

5. Progression during or within 6 months following administration of a standard regimen[2] for treatment of metastatic disease that included oxaliplatin with any of

the following agents with or without bevacizumab:

• 5-fluorouracil (F-FU) with or without leucovorin or levoleucovorin
• Capecitabine Note: In patients receiving FOLFOX, oxaliplatin is sometimes discontinued due to toxicity or as part of maintenance therapy strategy. If such patients progress while on 5-FU alone, they are eligible for this trial. As an example, a patient who is begun on FOLFOX or CapeOx (capecitabine with oxaliplatin, with or without bevacizumab), whose oxaliplatin is held for neurotoxicity and who is switched to capecitabine monotherapy or capecitabine with bevacizumab, would be considered to have had one prior therapy. OR Patients who develop metastatic disease within 9 months of adjuvant FOLFOX for stage II or III colon cancer

6. Measurable disease, defined as at least 1 unidimensionally measurable lesion on a CT scan as defined by RECIST 1.1.

7. Eastern Cooperative Oncology Group (ECOG) performance status =1 (see Appendix C)

8. Life expectancy of at least 3 months

• Glomerular filtration rate (GFR) =30 ml/min/1.73m2 (see Appendix A)
• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =3x ULN ( =5.0 × ULN for patients with liver involvement of their cancer

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression Free Survival (PFS)	To compare PFS between regorafenib + FOLFIRI chemotherapy (ARM A) versus placebo + FOLFIRI (ARM B) in patients failing one prior oxaliplatin-containing regimen for metastatic colorectal cancer. PFS is defined as the time from randomization until metastatic colorectal cancer (mCRC) progression or death as a result of any cause. Radiographic response will be measured by RECIST, Response Evaluation Criteria In Solid Tumors Criteria, indicating if subject experienced a Complete Response (CR), disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Stable Disease (SD), no response or less response than Partial or Progressive; or Progressive Disease (PD), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.	5.5 years
Secondary	Overall Response(OR)Rate	To compare overall response (OR) rates (OR= CR + PR) between ARM A and ARM B as defined via Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) 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.	3 years
Secondary	Disease Control (DC) Rate	To compare Disease Control (DC) Rate (DC= CR + PR + SD) between ARM A and ARM B as defined via Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) 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 and Stable Disease (SD) ), no response or less response than Partial or Progressive; or Progressive Disease (PD), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.	3 years
Secondary	Overall Survival (OS)	To compare overall survival (OS) between ARM A and ARM B. OS is defined as the time from randomization until death as a result of any cause.	5.5 years
Secondary	Drug Metabolism	To compare the pharmacokinetic (PK) profile of FOLFIRI between a subset of patients receiving regorafenib (ARM A) and patients receiving placebo (Arm B). The Area Under the Curve (AUC) levels of the irinotecan metabolite SN-38 were compared.	28 days
Secondary	Percentage of Patients With Severe Adverse Events	Toxicity Assessments were made according to NCI CTCAE v. 4.0 . Severe events (grades 3-4) that occurred in a higher percentage of regorafenib treated participants as compared to placebo are reported below.	3 years
