Single-center Investigator Initiated Pilot Study Investigating the Tumor Response of Squamous Cell Carcinoma Lesions in Patients Under Lapatinib Treatment

• Status: Terminated
• Trial end date: 2013-11-01
• Target enrollment: 0
• Participant gender: All

Summary

Primary cutaneous squamous cell carcinomas (SCCs) are epithelial carcinomas with a high frequency of EGF-R expression. EGFR is an important regulator of tumour progression and proliferation in several types of cancer. Mechanism of action of Lapatinib in the EGFR and/or HER2 expressing oesophageal squamous cell carcinoma (ESCC) cells is attributed to inhibition of cell proliferation and induction of apoptosis. Based on the data from oesophageal SCCs the investigators hypothesise that EGFR signalling pathway and its interactions play an important role in the SCC pathogenesis and represent a good therapeutic target from these tumours.

Primary Objectives:

To evaluate the tumour response macroscopically in patients with primary cutaneous SCC lesions and in concomitant SCC in situ (AK).

Secondary Objectives:

• To evaluate tolerability of a single dose regimen of systemic lapatinib therapy in patients with SCC as measured by time to first AE or SAE within the study period.

• To investigate the molecular tumour response of squamous cell carcinoma lesions in patients under lapatinib treatment using a set of variables.

• Trial with medicinal product

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

Exclusion criteria:

• Subjects who have current active hepatic or biliary disease

• Other non-controlled malignancy

• Clinically significant gastrointestinal abnormalities that may increase the risk for gastrointestinal bleeding.

• History of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 28 days of study treatment.

• Presence of uncontrolled infection

• History of any one or more of the following cardiovascular conditions within the past 6 months:Cardiac angioplasty or stenting;Myocardial infarction;Unstable angina;Coronary artery bypass graft surgery;Symptomatic peripheral vascular disease; Class III or IV congestive heart failure, as defined by the New York Heart Association (NYHA)
