A Randomized Phase I/II Study of Standard Chemotherapy (Cisplatin and Pemetrexed) With or Without Axitinib in Patients With Malignant Mesothelioma: Interim Biopsy Analysis to Determine Efficacy


To determine the effects of the addition of axitinib to standard chemotherapy on tissue
samples with respect to micro-vessel density (MVD): expression of VEGF-Receptor; PDGF
receptor expression; extent of necrosis and apoptosis.

To determine the safety of the addition of axitinib (to a maximum of the recommended dose of
maximally 2 x 10 mg per day) to the standard treatment with cisplatin and pemetrexed.

To determine the feasibility of performing a (second) thoracoscopy after 10 weeks of the
combination treatment with cisplatin, pemetrexed and axitinib.

Serum samples will be collected and tested for inhibiting effects in a tube formation and
spheroid sprouting assay.


Inclusion Criteria:



- histologically or cytologically diagnosed malignant mesothelioma

- age > 18 years

- Medically suitable for limited surgical intervention (pleural biopsies or limited
pleurectomy)

- Measurable or evaluable disease is not required

- Ability to understand the study and give signed informed consent including the
approval to accept a second thoracoscopic or surgical treatment after the third
course

- No previous chemotherapy

- Radiotherapy is allowed when this is given for palliation, the interval is > 4 weeks,
not more than 1/3 of the bone marrow capacity or all tumor is within the irradiation
field.
