Trial overview

Official title: An exploratory, phase II trial to determine the association of lapatinib induced fluoropyrimidine gene changes with efficacy parameters of lapatinib and capecitabine in first line gastric cancer
Trial description: The study will determine if changes in expression of markers involved in the 5-FU pathways are associated with response to treatment with the combination of lapatinib and capecitabine independent of tumor erbB2 status.
Primary purpose:
Treatment
Trial design:
Single Group Assignment
Masking:
None (Open Label)
Allocation:
Non-randomized
Primary outcomes:

Change from start of Run-in Period in biomarker expression levels at Day 0

Timeframe: evaluated at baseline and after 7 days of study treatment

Response rate (measured as the percentage of participants with response [complete response or partial response])

Timeframe: From Baseline (Day 0) until disease progression or death due to any cause evaluated every 6 or 12 weeks (up to approximately 85 weeks)

Percentage of participants (par.) with 5-month progression-free survival (PFS)

Timeframe: From initial treatment up to 24 weeks (next available assessment after the 5-month assessment for progressive disease)

Secondary outcomes:

PFS

Timeframe: From Baseline (Day 0) until disease progression or death due to any cause (up to approximately 85 weeks)

Overall Survival (OS)

Timeframe: From Baseline (Day 0) until death due to any cause evaluated at approximately 12 months (up to approximately 100 weeks)
