General information
Database:DB00115
Objective:This trial was designed to determine the safety and efficacy of lapatinib in hepatocellular carcinoma.
Authors:BekaiiSaab T, et al
Title:A multiinstitutionalphase II study of the efficacy and tolerability of lapatinib in patients with advanced hepatocellular carcinomas.
Journal:Clin Cancer Res.
Year:2009
PMID:19737952
Trial Design
Clinical Trial Id:NA
Agent:lapatinib
Target:Epidermal growth factor receptor
Receptor proteintyrosine kinase erbB2
Cancer Type:liver cancer
Cancer Subtype:advanced hepatocellular carcinoma
Therapy Type:mono
Therapeutic Combination Type:NA
Therapeutic Combination Content:NA
Study Type:an openlabel, singlearm, multicenterphase II study
Key Patients Feature:histologically confirmed unresectable advanced hepatocellular carcinoma and measurable disease per RECIST, less than and equal to 1 prior systemic anticancer therapy;
Biomarker:expression of human epidermal growth factor receptor 2/NEU/CEP17 and status of downstream signal pathway proteins(did not correlate with survival)
Biomark Analysis:they did not find evidence of human epidermal growth factor receptor 2/NEU somatic mutations. PTEN, PAKT, and P70S6K expression did not correlate with survival
Control Group Info:single arm
Treatment Info:1, 500 mg/day administered orally in 28day cycles
Primary End Point:ORR as defined by RECIST criteria.
Secondary End Point:toxicity, OS, assessment of mutations of EGFR and human epidermal growth factor receptor 2/neu genes and measurement of expression of proteins in signaling pathways relevant to lapatinib including human epidermal growth factor receptor 2/neu, PTEN, PAkt, and P70S6K.
Patients Number:26
Trial Results
DLT_MTD:NA
Objective Response Rate:No objective responses were observed. Ten (40%) patients had stable disease as their best response including six (23%) with stable disease lasting >120 days.
Disease Control Rate:NA
Median Time to Progression:NA
Median PFS A vs. C:1.9
Median OS A vs. C:12.6, patients who developed a rash had a borderline statistically significant longer survival.
Adverse Event(agent arm):Most common toxicities were diarrhea (73%), nausea (54%), and rash (42%).
Conclusions:Lapatinib is welltolerated but seems to benefit only a subgroup of patients for whom predictive molecular or clinical characteristics are not yet fully defined.
