Study Comparing Veliparib Plus FOLFIRI Versus Placebo Plus FOLFIRI With or Without Bevacizumab in Previously Untreated Metastatic Colorectal Cancer

November 16, 2018 updated by: AbbVie

Randomized, Blinded, Multicenter, Phase 2 Study Comparing Veliparib Plus FOLFIRI ± Bevacizumab Versus Placebo Plus FOLFIRI ± Bevacizumab in Previously Untreated Metastatic Colorectal Cancer

This was a blinded, randomized, placebo-controlled Phase 2 multicenter study evaluating the efficacy and tolerability of veliparib plus irinotecan, fluorouracil, and leucovorin chemotherapy regimen (FOLFIRI) compared to placebo plus FOLFIRI in participants with previously untreated metastatic colorectal cancer. Participants could also have been treated with bevacizumab at the discretion of the Investigator.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Participants were randomized to one of 2 groups: veliparib plus FOLFIRI ± bevacizumab (veliparib group) or placebo plus FOLFIRI ± bevacizumab (placebo group), and stratified by planned use of bevacizumab (planned bevacizumab use compared to unplanned use of bevacizumab) and regions of the world (North America versus rest of world). In this study, the term FOLFIRI was used to describe both the standard regimen containing a fluorouracil bolus that was administered to participants randomized to the placebo arm, and a modified regimen with a saline bolus that was administered to participants randomized to the veliparib arm. One cycle of protocol therapy consisted of 14 days, defined as Day -2 through Day 12. Dosing of oral veliparib/placebo began 2 days prior to the start of FOLFIRI and continued twice a day for a total of 7 consecutive days. At the discretion of the Investigator, bevacizumab could be administered intravenously immediately preceding FOLFIRI. Study visits were conducted on Day 1 and Day 8 of the first and second cycles, then on Day 1 of each subsequent cycle. Participants were to continue protocol therapy and study visits until they met one of the defined discontinuation criteria. When the Investigator determined that a participant met the criteria for discontinuation, a final visit was conducted. Participants were to have had one follow-up visit approximately 30 days after the last dose of protocol therapy. Sites began collecting post-treatment and survival information 4 weeks after the last clinical assessment. Post-baseline radiographic tumor assessment was to be conducted every 8 weeks from Cycle 1, Day 1 (prior to the start of a new cycle) until radiographic progression.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Progression-Free Survival (PFS): Time to Event
Time Frame: Every 8 weeks from Cycle 1, Day 1 until radiographic progression was observed. The maximum observed follow up duration at the progression-free survival analysis time was 579 days.
PFS was defined as the number of days from the date the participant was randomized to the date the participant experienced an event of disease progression or death, whichever occurred first. All events of disease progression were included, whether the participant was still taking or had discontinued study drug. Events of death were included for participants who had not experienced an event of disease progression, if the death occurred within 8 weeks of the last evaluable disease progression assessment. If the participant did not have an event of disease progression and the participant had not died as defined above, data were censored at the date of the participant's last evaluable disease progression assessment. The PFS distribution was estimated using Kaplan-Meier methodology. Point estimates and 95% confidence intervals (95% CIs) for the PFS distribution quartiles are provided.
Every 8 weeks from Cycle 1, Day 1 until radiographic progression was observed. The maximum observed follow up duration at the progression-free survival analysis time was 579 days.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Survival (OS): Time to Event
Time Frame: Survival information was to be collected 4 wks after the last study visit, continuing every 4 wks for 1 yr, then every 8 wks for up to 2 more yrs or until death. The maximum observed follow up duration at the overall survival analysis time was 914 days.
Overall survival was defined as the number of days from the date that the participant was randomized to the date of the participant's death. All events of death were included, regardless of whether the event occurred while the participant was still taking or had discontinued study drug. If a participant had not died, the data were censored at the date last known to be alive. The OS distribution was estimated using Kaplan-Meier methodology. Point estimates and 95% confidence intervals (95% CIs) for the OS distribution quartiles are provided.
Survival information was to be collected 4 wks after the last study visit, continuing every 4 wks for 1 yr, then every 8 wks for up to 2 more yrs or until death. The maximum observed follow up duration at the overall survival analysis time was 914 days.
Objective Response Rate (ORR)
Time Frame: Per protocol, post-baseline tumor assessment was conducted every 8 weeks from Cycle 1 Day 1 until radiographic progression. The maximum observed follow up duration at the progression-free survival analysis time was 579 days.
ORR was defined as the proportion of participants with a complete (CR) or partial response (PR) based on Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1) for target lesions, assessed by computed tomography (CT). Complete response (CR) was defined as disappearance of all target lesions; partial response (PR) ≥30% decrease in the the sum of diameters of target lesions, taking as reference the baseline sum diameters. For participants who underwent surgery, ORR was not evaluated after surgery.
Per protocol, post-baseline tumor assessment was conducted every 8 weeks from Cycle 1 Day 1 until radiographic progression. The maximum observed follow up duration at the progression-free survival analysis time was 579 days.
