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. |
