A Phase IIa Study of the MEK Inhibitor Trametinib Monotherapy in the Treatment of Biliary Tract Cancers

3 de mayo de 2017 actualizado por: GlaxoSmithKline

A Phase IIa Study of the MEK Inhibitor GSK1120212 Monotherapy in the Treatment of Gemcitabine Refractory Locally Advanced, Recurrent or Metastatic Biliary Tract Cancers

This is a Phase IIa, open-label, single-arm, multi-center study to evaluate the efficacy and safety of orally administered MEK inhibitor trametinib as the second line in subjects with advanced or metastatic biliary tract cancers (BTC) in Japanese population. The primary endpoint of this study is 12 week non-progressive disease (PD) rate defined as the percentage of subjects without progression at Week 12. As a sub-study, pharmacokinetics (PK) of four tablets of 0.5 milligram (mg) tablet, or one tablet of 2 mg tablet to achieve 2 mg daily regimen will be assessed to evaluate the pharmacokinetics of trametinib in Japanese population.

Eligible subjects will be randomized to receive trametinib at the recommended Phase II dose of 2 mg every day as one 2 mg tablet or four 0.5 mg tablets on Day 1. From Day 2 until disease progression or withdrawal from the study treatment, all subjects will receive one tablet of 2 mg trametinib . Disease assessment will be performed every 8 week. Translational research is also planned to evaluate the potential blood or tumor tissue-derived biomarkers for biological activity, and sensitivity or resistance to treatment with trametinib .

Periodo de tiempo: Up to Week 37
Progression-Free Survival (PFS) is defined as the interval of time (in weeks) between the date of randomization and the earlier of the date of disease progression and the date of death due to any cause. Disease progression was based on the assessments by the Investigator. If a participant received subsequent anti-cancer therapy prior to the date of documented progression or death, PFS in the participant was censored at the last adequate assessment prior the initiation of the new anti-cancer therapy. Otherwise, if a participant did not have a documented date of progression or death, PFS in the participant was censored at the last adequate assessment.

Periodo de tiempo: Up to Week 37
Progression-Free Survival (PFS) is defined as the interval of time (in weeks) between the date of randomization and the earlier of the date of disease progression and the date of death due to any cause. Disease progression was based on the assessments by the independent radiologist. If a participant received subsequent anti-cancer therapy prior to the date of documented progression or death, PFS in the participant was censored at the last adequate assessment prior the initiation of the new anti-cancer therapy. Otherwise, if a participant did not have a documented date of progression or death, PFS in the participant was censored at the last adequate assessment.

Death on study due to any cause was included. One year OS was calculated from Kaplan-Meier estimates.
Up to Week 39
Number of Participants With Overall Response Rate as Assessed by Investigator Per RECIST 1.1 Criteria
Periodo de tiempo: Up to Week 37
Overall Response Rate (ORR) is defined as the number of participants achieving a confirmed CR or PR per RECIST 1.1 criteria from the start of treatment until disease progression or the start of new anti-cancer therapy.

ORR is calculated as CR + PR.
Up to Week 37
Number of Participants With Overall Response Rate as Assessed by Independent Radiologist Per RECIST 1.1 Criteria
Periodo de tiempo: Up to Week 37
Overall Response Rate (ORR) is defined as the number of participants achieving a confirmed CR or PR per RECIST 1.1 criteria from the start of treatment until disease progression or the start of new anti-cancer therapy.

Periodo de tiempo: Up to Week 37
Time to response (TTR) event was defined as achievement of a confirmed CR or PR, as the time from date of randomization until date of first documented evidence of CR or PR (whichever status is recorded first). If a participant received subsequent anti-cancer therapy prior to the date of documented progression or death, progression free survival (PFS) in the participant was censored at the last adequate assessment prior the initiation of the new anti-cancer therapy. Otherwise, if a participant did not have a documented date of progression or death, PFS in the participant was censored at the last adequate assessment.
Up to Week 37
Number of Weeks Until Time to Response Assessed With Independent Radiologist
Periodo de tiempo: Up to Week 37
Time to response (TTR) event was defined as achievement of a confirmed CR or PR, as the time from date of randomization until date of first documented evidence of CR or PR (whichever status is recorded first). If a participant received subsequent anti-cancer therapy prior to the date of documented progression or death, progression free survival (PFS) in the participant was censored at the last adequate assessment prior the initiation of the new anti-cancer therapy. Otherwise, if a participant did not have a documented date of progression or death, PFS in the participant was censored at the last adequate assessment. Only 1 participant reached PR therefore estimated time to response cannot be presented. The time to response for this patient is presented as the actual number of weeks to PR.
Up to Week 37
Number of Participants With Investigator-Assessed Duration of Response
Periodo de tiempo: Up to Week 37
Duration of response was summarized for participants with a confirmed CR or PR and is defined as the time (in weeks) from the initial response (CR/PR) to first documented disease progression or death due to any cause. If a participant received subsequent anti-cancer therapy prior to the date of documented progression or death, PFS in the participant was censored at the last adequate assessment prior the initiation of the new anti-cancer therapy. Otherwise, if a participant did not have a documented date of progression or death, PFS in the participant was censored at the last adequate assessment.
Up to Week 37
Number of Participants With Independent Radiologist Assessed Duration of Response
Periodo de tiempo: Up to Week 37
Duration of response was summarized for participants with a confirmed CR or PR and is defined as the time (in weeks) from the initial response (CR/PR) to first documented disease progression or death due to any cause.
