Patients must have failed prior standard therapies associated with clinical benefits, including survival benefits, if such therapies are available. If docetaxel administration is standard therapy associated with clinical benefits, patients are eligible

• Patients must be recovered from previous surgery

Exclusion criteria

• Active infectious disease
• Gastrointestinal disorders that may interfere with the absorption of the study drug or chronic diarrhea
• Serious illness or concomitant non-oncological disease considered by the investigator to be incompatible with the protocol
• Patients with untreated or symptomatic brain metastases. Patients with treated, asymptomatic brain metastases are eligible if there has been no change in brain disease status for at least eight weeks, no history of cerebral edema or bleeding in the past eight weeks and no requirement for steroids or anti-epileptic therapy
• Cardiac left ventricular function with resting ejection fraction ≥ CTC Grade 1
• Absolute neutrophil count (ANC) less than 1500 / mm3
• Platelet count less than 100 000 / mm3
• Bilirubin > upper limit of normal (ULN)
• Aspartate amino transferase (AST) and / or alanine amino transferase (ALT) > 1.5 x ULN
• Alkaline Phosphatase > 2.5 x ULN
• Serum creatinine > 1.5 mg / dl (> 132 μmol / L, SI (Système Internationale) unit equivalent)
• Women and men who are sexually active and unwilling to use a medically acceptable method of contraception
• Pregnancy or breast-feeding
• Concurrent treatment with other investigational drugs, or chemotherapy, immunotherapy, radiotherapy or hormone therapy (excluding Luteinizing hormone-releasing hormone agonists, or other hormones taken for breast cancer, or bisphosphonates) or participation in another clinical study within the past four weeks before start of therapy or concomitantly with this study

The patient may be eligible for re-treatment after the previous course is finished. The patient will not be eligible if any of the following conditions are met:

• If patients' latest X-ray, CT or MRI reveals progressive disease, or if clinical assessment reveals signs of disease progression
• Cardiac left ventricular function CTC Grade ≥ 2 at any time during the previous course
• Patients fulfilling any of the Exclusion Criteria listed before as determined before treatment Day 1 of any new course
• Patient not recovered from any dose-limiting toxicity (DLT) 14 days after onset. Recovery is defined as a return to baseline level or CTC Grade 1, whichever is higher
