Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Histologically confirmed stage IV colon cancer (AJCC 7th edition) that has progressed after standard therapy that included 5-FU, irinotecan, oxaliplatin and appropriate antibody therapy. Antibody therapy with bevacizumab and an anti-EGFR antibody, if RAS wild type, should have been given unless medical reasons have precluded their use. Participants who could not tolerate standard agents because of unacceptable, but reversible toxicity necessitating their discontinuation will be allowed to participate.
  • Participants who had received adjuvant chemotherapy and had recurrence during or within six months of completion of the adjuvant chemotherapy will be allowed to count the adjuvant therapy as one chemotherapy regimen for advanced disease.
  • Progression of disease must be documented on the most recent scan.
  • Presence of measurable disease
  • RAS mutation and MMR status must be determined (or tissue availability for testing if not already determined).
  • Age 18 years or older.
  • ECOG performance status 0-1.
  • Life expectancy of at least three months.

  • Participants with adequate organ function:

    1. Absolute neutrophil count (ANC) > 1.5 x 109/L
    2. Hemoglobin > 9 g/dL
    3. Platelets (PLT) > 70 x 109/L
    4. AST/ALT < 5 x ULN
    5. Albumin within normal limits for institution
  • Women who are nursing and discontinue nursing prior to enrollment in the program.
  • Ability to take oral medication (i.e., no feeding tube).
  • Participant able and willing to comply with study procedures as per protocol.
  • Participant able to understand and willing to sign and date the written voluntary informed consent form (ICF) at screening visit prior to any protocol-specific procedures.

Exclusion Criteria:

  • Participants who have previously received TAS-102.
  • Grade 3 or higher peripheral neuropathy (functional impairment).
  • Inability to tolerate irinotecan previously (due to uncontrolled diarrhea)
  • There are no specific exclusions for bevacizumab. Bevacizumab should be given unless there are specific contraindications per the treating investigator, which should be stated. If UPC is >1.0 (as above) hold bevacizumab until proteinuria resolves and then start bevacizumab.
  • Symptomatic CNS metastases requiring treatment.
  • Other active malignancy within the last three years (except for non-melanoma skin cancer or a non-invasive/in situ cancer).
  • Pregnancy or breast feeding.
  • Current therapy with other investigational agents.
  • Active infection with body temperature > 38°C due to infection.
  • Major surgery within prior four weeks (the surgical incision should be fully healed prior to drug administration).
  • Any anticancer therapy within prior two weeks of first dose of study drug.
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to TAS-102.
  • Current therapy with other investigational agents or participation in another clinical study or any investigational agent received within prior four weeks.
  • Grade 3 or higher hypersensitivity reaction to oxaliplatin or irinotecan, or grade 1-2 hypersensitivity reaction to oxaliplatin not controlled with pre-medication.
  • Has unresolved toxicity of greater than or equal to Common Terminology Criteria for Adverse (CTCAE) Grade 2 attributed to any prior therapies (excluding anemia, alopecia, skin pigmentation, and platinum-induced neurotoxicity).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Disease control rate (DCR):
Time Frame: From baseline until the date of first documented progression of disease, as assessed up to 100 months
Defined as the percentage of patients who have achieved complete response (CR), partial response (PR) and stable disease (SD). The disease control rate will be calculated along with 95% confidence interval. As Simon's two stage design is used in the study, 95% CI will be calculated for the two-stage nature of the study design. Response will be determined by independent radiologists using the RECIST criteria.
From baseline until the date of first documented progression of disease, as assessed up to 100 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression Free Survival (PFS)
Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, on average up to 100 months
Progression Free Survival (PFS) Progression will be assessed by a CT scan according to RECIST criteria version 1.1. This criterion will be estimated by the median time based on a Kaplan-Meier method. Patients who have not progressed or died at the time of analysis will be censored at the time of their latest follow-up with clinically stable disease. This includes participants who withdraw consent.
From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, on average up to 100 months
Overall Survival (OS)
Time Frame: From date of randomization until the date of death up to 100 months
This will be analyzed and plotted using the Kaplan-Meier method.
From date of randomization until the date of death up to 100 months
Overall Response Rate (ORR)
Time Frame: From the date of randomization and measured through the course of study treatment, assessed up to 100 months

This will be calculated along with 95% confidence interval.

Response rate is defined as the percentage of subjects with a confirmed complete response (CR) or partial response (PR) by investigator assessment as per RECIST criteria, version 1.1. A maximum of five measurable lesions in total (and up to 2 per organ) representative of all involved organs should be identified as target lesions at baseline and measured through the course of study treatment. At baseline, the sum of the diameters (longest diameters (LD) for extra nodal target lesions and short axis diameters (SAD) for nodal lesions) will be calculated and reported as the baseline sum LD. This baseline sum LD will be used as the reference by which to characterize the objective tumor response. All other lesions should be identified as non-target lesions and should also be recorded at baseline. Measurements of these lesions are not required, but the presence or absence of each should be noted throughout the study
From the date of randomization and measured through the course of study treatment, assessed up to 100 months
Duration of Response
Time Frame: From the date of response until the date of first documented disease progression or death, assessed up to 100 months
Response will be determined by independent radiologist using RECIST 1.1. Time to progression for responders will be analyzed by Kaplan-Meier methods.
From the date of response until the date of first documented disease progression or death, assessed up to 100 months
