E.3 | Principal inclusion criteria |
• Patients with histologically or cytologically proven malignant mesothelioma
• Age >18 years.
• At the date of randomisation, the patients must have completed 4 cycles of first-line chemotherapy with a platinum (cisplatin or carboplatin) and pemetrexed combination at least 21 days but no more than 42 days prior to study entry, and have no evidence of progressive disease following first-line treatment.

- Hematologie: Neutrofielen ≥ 1.5 x 109/l, Thrombocyten ≥ 100 x 109/l, Hemoglobine ≥ 6.2 mmol/l.
- Lever functie gedefinieerd als serum bilirubin ≤ 1.25 x ULN, ALT en AST ≤ 2.5 x ULN, behalve als er sprake is van levermetastasen, dan mag het ALAT en ASAT < 5 x ULN zijn.
- Nierfunctie gedefinieerd als serum creatinine ≤ 1.25 x ULN of creatinine klaring ≥ 50 ml/min (berekend met de Cockcroft-Gault formule).
