Study of REOLYSIN® in Combination With FOLFIRI in Patients With Oxaliplatin Refractory/Intolerant KRAS Mutant Colorectal Cancer
This is a Phase 1 dose-escalation study with three dose levels to determine the maximum tolerated dose of REOLYSIN combined with FOLFIRI.

|Official Title:||A Multicenter Phase 1 Study of Intravenous Administration of REOLYSIN® (Reovirus Type 3 Dearing) in Combination With Irinotecan/Fluorouracil/Leucovorin (FOLFIRI) in Patients With KRAS Mutant Metastatic Colorectal Cancer|
- Dose limiting toxicity to define maximum tolerated dose and recommended Phase 2 dose [ Time Frame: During the first cycle of treatment (4 week cycle) ] [ Designated as safety issue: Yes ]
- Pharmacokinetic parameters for irinotecan and 5-FU when combined with REOLYSIN® [ Time Frame: During the first cycle of treatment (4 week cycle) ] [ Designated as safety issue: No ]
- Objective response, clinical benefit rate, progression-free survival, and overall survival [ Time Frame: Assessed every 8 weeks until disease progression or death ] [ Designated as safety issue: No ]
- Safety and tolerability of study treatment [ Time Frame: During study and within 30 days of the last dose of REOLYSIN ] [ Designated as safety issue: Yes ]

|Estimated Primary Completion Date:||December 2012 (Final data collection date for primary outcome measure)|
Reovirus Serotype 3 - Dearing Strain (REOLYSIN) is a naturally occurring, ubiquitous, non-enveloped human reovirus. Reovirus has been shown to replicate selectively in Ras-transformed cells causing cell lysis. Activating mutations in ras or mutation in oncogenes signaling through the ras pathway may occur in as many as 80% of human tumors. The specificity of the reovirus for Ras-transformed cells, coupled with its relatively nonpathogenic nature in humans, makes it an attractive anti-cancer therapy candidate. Eligible patients for this study include those with histologically confirmed cancer of the colon or rectum with Kras mutation and measurable disease.
Cetuximab and panitumumab have shown to be ineffective in patients whose tumors have a KRAS mutation. Therefore, currently, for patients with a KRAS mutation, the only option after failure of front-line therapy is irinotecan or FOLFIRI, and there is no drug that can be combined with it to improve clinical outcomes.
The trial is a Phase I dose escalation study with four dose levels, comprising cohorts of three to six patients, to determine a maximum tolerated dose and dose-limiting toxicities with the combination of REOLYSIN and FOLFIRI. FOLFIRI will be administered on the first day of a two week (14-day) cycle, while REOLYSIN will be administered on days one through five of a four week (28-day) cycle.
The study is expected to enroll 12 to 20 patients.
