Study of Ruxolitinib in Colorectal Cancer Patients

A Randomized, Double-Blind Study of Ruxolitinib or Placebo in Combination With Regorafenib in Subjects With Relapsed or Refractory Metastatic Colorectal Cancer

The purpose of this study was to determine if ruxolitinib, in combination with regorafenib, is safe and effective in the treatment of metastatic colorectal cancer.

Study Overview

• Status: Terminated
• Conditions: CRC (Colorectal Cancer)
• Intervention / Treatment: Drug: Placebo; Drug: Ruxolitinib; Drug: Regorafenib

Detailed Description

The study consisted of an open-label, Part 1 safety run-in (consisting of 1 to 3 cohorts of 9 subjects each), to confirm the safety of the regorafenib/ruxolitinib combination in subjects with relapsed or refractory metastatic colorectal cancer (CRC). If determined to be tolerable, Part 2 was to proceed as a randomized, double-blind study evaluating ruxolitinib or placebo in combination with regorafenib in subjects with relapsed or refractory metastatic CRC previously treated with fluoropyrimidine, oxaliplatin, and/or irinotecan based chemotherapy, an anti-vascular endothelial growth factor (VEGF) therapy and if Kirsten rat sarcoma (KRAS) wild type an anti-epidermal growth factor receptor (EGFR) therapy.

Subjects in the safety run-in received open-label ruxolitinib and regorafenib; for the randomized, double-blind portion of the study all subjects received regorafenib and either ruxolitinib or placebo in a 1:1 blinded manner. Treatment for all subjects consisted of repeating 28-day cycles. Regorafenib was self-administered for the first 21 days of each cycle, and ruxolitinib/placebo was self-administered during the entire 28-day cycle. Treatment cycles continued as long as the regimen is tolerated, and the subject does not meet the discontinuation criteria. When subjects discontinued regorafenib, ruxolitinib or placebo they remained in the study and were followed for subsequent treatment regimens which were initiated and survival.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival (OS)	Overall survival is defined as the time from randomization to death due to any cause. Participants without death observed at the time of the analysis will be censored at last date known to be alive. The median overall survival time was estimated using the Kaplan-Meier method. Overall survival was compared between treatment groups using log-rank test.	Baseline until death due to any cause; up to 16 months or data cut-off 11 FEB 2016.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression Free Survival (PFS)	Progressive Disease (PD) is defined using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 at least a 20% increase in the sum of the Longest Diameter (LD) of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions, unequivocal progression of non-target lesions, or the appearance of new lesions.	Baseline through disease progression, or death due to any cause if sooner; up to 16 months or data cut-off 11 FEB 2016.
Overall Response Rate (ORR)	Response defined per Response Evaluation Criteria In Solid Tumors (RECIST) criteria: Complete Response (CR)=disappearance of all target and non-target lesions without new lesion; Partial Response (PR)=30% decrease in sum of longest diameter of target lesions, non-target lesion not progressed, and no new lesion; Progressive Disease=20% increase in sum of longest diameter of target lesions, or non-target lesion progression, or identification of new lesion; Stable Disease=small changes that do not meet above criteria. ORR was defined as the proportion of participants who achieved a best response of either CR or PR. ORR=number of participants with CR or PR/number of participants randomized.	Baseline through end of study; up to 16 months or data cut-off 11 FEB 2016.
Duration of Response	Duration of response is defined as the time from response (CR/PR) until the earliest date of disease progression determined by investigator assessment of objective radiographic disease assessments per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, or death due to any cause.	Baseline through end of study; up to 16 months or data cut-off 11 FEB 2016.
Percentage of Participants Achieving Disease Control	Disease control as measured by the percentage of participants whose best response was complete response (CR), partial response (PR), or stable disease (SD) per RECIST v.1.1.	Baseline through end of study; up to 16 months or data cut-off 11 FEB 2016.
Percentage of Participants With Treatment-emergent Adverse Events (TEAEs)	TEAEs were defined as any adverse event (AE) during the study that began or worsened on or after the date of first dose of investigational product.	Baseline through approximately 30 days post treatment discontinuation;up to 16 months or data cut-off 27JAN 2016 for Substudy 1 and up to the data cut-off of 11FEB2016 for Substudy 2.
