Principal objective: to evaluate the effect of the combination pravastatin - sorafenib versus sorafenib alone on overall survival in patients with hepatocellular carcinoma developing on Child-Pugh A cirrhosis who are unsuitable for curative treatment.

Secondary objectives: evaluate the effect of this treatment on progression-free survival, the time to progression, the time to treatment failure and quality of life (QLQ-C30 et FACT HEP)

Inclusion Criteria:

• Hepatocellular carcinoma diagnosed by:
• either a histological examination
• or if histological evidence cannot be obtained (ascites, coagulation disorders) the diagnosis can be made in cases of cirrhosis according to EASL/AASLD 2005 criteria, by revealing a hepatic focal lesion of more than 10 mm
• on two dynamic imaging techniques (helical CT-scan, MRI, contrast-enhanced ultrasound) for tumours measuring less than 2 cm. The lesion must be characterised by hyperdensity during the arterial phase and wash-out during the delayed portal phase Patients who are not suitable for treatment with a curative intent (transplantation, resection, percutaneous destruction) or by chemo-embolisation or with progressive hepatocellular carcinoma after the failure of specific treatment Prognostic CLIP score 0 to 4 Child-Pugh Class A Transaminases ≤ 5 N and Creatininemia ≤ 1.5 N WHO: 0, 1 or 2 Age more than 18 years Foreseeable survival > 12 weeks Possibility of regular follow-up Written informed consent

Exclusion Criteria:

• Extra-hepatic disease that could be life-threatening in the short or medium term Another progressive cancer with the exception of in situ cervical cancer, a superficial bladder tumour and treated basocellular carcinoma.

Any other cancer treated with a curative intent in the previous 3 years can be included in the study Heart failure (≥New York Heart Association class 2), uncontrolled AHT or arrhythmia, myocardial infarction in the previous 6 months Digestive haemorrhage in the previous month Patients who are receiving or have already received treatment with statins or sorafenib Pregnancy and breast-feeding. Women of child-bearing age must use an effective method of contraception throughout the trial and for 3 months after the end of the treatment.
