Brief Summary:
A Phase 2 Study with Safety Lead-in, Evaluating TAS-102 Plus Nivolumab in Participants with Microsatellite Stable Refractory Metastatic Colorectal Cancer

Condition or disease Intervention/treatment Phase
Refractory Metastatic Colorectal Cancer Drug: TAS-102 Drug: nivolumab Phase 2

Detailed Description:

This is a multicenter, single arm, safety lead-in, Phase 2 study, using Simon's 2 stage design evaluating the safety and efficacy of TAS-102 plus nivolumab in participants with Microsatellite-stable refractory metastatic colorectal cancer

Stage 1: Participants will be enrolled and after Cycle 1 treatment, they will be evaluated for the safety and tolerability of the combination therapy. Assuming a tolerated dose is confirmed additional participants evaluable for response will be enrolled and followed for a minimum of 6 months and there will be an interim analysis to assess the safety and efficacy to determine whether the second stage will open for enrollment.

Stage 2: Additional participant evaluable for response assessment will be enrolled and followed for a minimum of 6 months.

    irORR was defined as the percentage of participants achieving a complete response (irCR) or partial response (irPR) based on irRC criteria. Per irRC criteria, Complete Response (irCR) was defined as the disappearance of all tumor lesions (measurable or not, and no new lesions)., Partial Response (irPR) was defined as a decrease in the sum of the products of the two largest perpendicular diameters (SPD) by 50 percent (%) or greater by a consecutive assessment at least 4 weeks after first documentation, Stable Disease (irSD) was defined as the failure to meet criteria for irCR or irPR in absence of progressive disease (irPD), irPD was defined as at least 25% increase in SPD relative to nadir.


Secondary Outcome Measures :
  1. Number of Participants With Dose Limiting Toxicities (DLTs) [ Time Frame: Cycle 1 (each cycle is of 4 weeks) ]

    DLT: defined as occurrence of any of the following-

    Hematological toxicities:

    • Grade 4 neutropenia lasting greater than(>)7 days
    • Grade 4 febrile neutropenia and fever greater than or equal to (>=)38 degree celsius for over 1 hour
    • Grade 4 thrombocytopenia or grade 3 thrombocytopenia associated with bleeding or requiring transfusions

    Non-hematological toxicities:

    • Grade 3 or grade 4 non-hematologic toxicity (excluding alopecia, nausea, vomiting, diarrhea)
    • Grade 3 or grade 4 nausea/vomiting lasting >48 hours and uncontrolled by aggressive anti-emetic therapy, including serotonin 5-HT3 receptor antagonists (e.g, ondansetron)
    • Grade 3 or grade 4 diarrhea lasting > 48 hours and unresponsive to antidiarrheal medication

    Drug-related toxicities:

    • Any drug-related toxicity resulting in > 2 weeks delay in initiation of Cycle 2 (i.e, cannot start Cycle 2 until Day 43 or later)
    • Any drug-related toxicity that prevents completion of 80% compliance for either drug in Cycle 1

  2. Recommended Phase 2 Dose (RP2D) [ Time Frame: Cycle 1 (each cycle is of 4 weeks) ]
    RP2D of TAS-102 was evaluated based on the safety and tolerability of the combination therapy of TAS-102 and Nivolumab.

  3. Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs) [ Time Frame: From first dose of study treatment up to 30 days after the last dose of study treatment (up to 53 weeks) ]
    An adverse event (AE) was defined as any untoward medical condition that occurs in a participants while participating in a clinical study and does not necessarily have a causal relationship with the use of the study treatment. A serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in any of the following outcomes: death, life-threatening, required initial or prolonged in-patient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or considered as medically important event. TEAEs: AEs that developed or worsened during the on-treatment period which was defined as the period from the time of first dose of study treatment until 30 days after the last dose of study treatment.

  4. Number of Participants With Grade 3 or Higher Laboratory Tests Abnormalities [ Time Frame: From first dose of study treatment up to 30 days after the last dose of study treatment (up to 53 weeks) ]
    Hematological and chemistry laboratory tests abnormalities were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 4.03. as: Grade 1 (Mild, asymptomatic or mild symptoms); Grade 2 (Moderate, minimal, local or noninvasive intervention indicated); Grade 3 (Severe or medically significant but not immediately life-threatening, hospitalization or prolongation of hospitalization indicated); Grade 4 (Life-threatening consequences, urgent intervention indicated); Grade 5 (Death related to AE).

  5. Overall Response Rate (ORR) [ Time Frame: From first dose of study treatment up to 30 days after the last dose of study treatment (up to 53 weeks) ]
    ORR was defined as the percentage of participants with objective evidence of complete response (CR) or partial response (PR) per response evaluation criteria in solid tumors (RECIST) version 1.1.CR was defined as the disappearance of all target lesions. Any pathological lymph nodes must have reduction in short axis to less than (<)10 millimeters (mm). PR was defined as at least a 30 % decrease in the sum of diameters of the target lesions, taking as a reference the baseline sum diameters.

  6. Progression-Free Survival (PFS) Based on Immune Related Response-Criteria (irRC) [ Time Frame: From the first dose of study treatment to disease progression or death (up to 53 weeks) ]
    Immune-related progression free survival was defined as the time (in months) from the date of first dose of study treatment until the date of the investigator-assessed radiological disease progression (based on irRC) or death due to any cause. Participants who were alive with no disease progression at the moment of the analysis cut-off date was censored at the date of the last tumor assessment. Per irRC criteria disease progression defined as at least 25% increase in SPD relative to nadir. Analysis was performed using Kaplan-Meier estimates.

  7. Progression-Free Survival (PFS) Based on RECIST Criteria [ Time Frame: From the first dose of study treatment to disease progression or death (up to 53 weeks) ]
    Progression free survival was defined as the time (in months) from the date of first dose of study treatment until the date of the investigator-assessed radiological disease progression (based on RECIST 1.1) or death due to any cause. Per RECIST criteria disease progression defined as least 20% increase in the sum of diameters of the target lesions, taking as a reference the smallest sum on study, including the baseline sum. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Definitive new lesion presence also indicated progression.

  8. Disease Control Rate (DCR) Based on irRC Criteria [ Time Frame: From first dose of study treatment up to 30 days after the last dose of study treatment (up to 53 weeks) ]
    DCR was defined as the percentage of participants with objective evidence of radiologic complete response (CR), partial response (PR), or stable disease (SD) and was based on the overall best response from each participant as determined from investigator response assessments and following irRC criteria. Per irRC criteria, CR was defined as the disappearance of all tumor lesions (measurable or not, and no new lesions). PR was defined as a decrease in the sum of the products of the two largest perpendicular diameters by 50% or greater by a consecutive assessment at least 4 weeks after first documentation. SD was defined as the failure to meet criteria for irCR or irPR in absence of in absence of irPD.

  9. Disease Control Rate (DCR) Based on RECIST Criteria [ Time Frame: From first dose of study treatment up to 30 days after the last dose of study treatment (up to 53 weeks) ]
    DCR was defined as the percentage of participants with objective evidence of radiologic CR, PR, or SD and was based on the overall best response from each participant as determined from investigator response assessments and following RECIST Criteria version 1.1. Per RECIST Criteria CR defined as disappearance of all target lesions. Reduction in any pathological lymph nodes in short axis to <10 mm. PR defined as at least a 30% decrease in the sum of diameters of the target lesions, taking as a reference the baseline sum diameters. SD defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as a reference the smallest sum diameters during study.

  10. Overall Survival (OS) [ Time Frame: From first dose of study treatment up to 30 days after the last dose of study treatment (up to 53 weeks) ]
    OS was defined as the time from the first dose of the study treatment to the death in the safety population. Participants alive at the time of the study discontinuation were censored. Analysis was performed using Kaplan-Meier estimates.
