Patients with pathologically confirmed diagnosis of advanced, recurrent breast cancer with at least one progressive and/or new metastatic brain lesion, that are refractory to standard therapy or for whom no standard therapy exist.

SCLC brain metastases study arm of the expansion phase:

Stable or decreasing dosages of steroids (e.g. dexamethasone) for 7 days prior to baseline MRI and/or use of non-enzyme inducing anti-epileptic drugs are allowed.

Or

Patients with pathologically confirmed diagnosis of advanced SCLC with newly diagnosed, untreated, brain metastases and controlled extracranial disease which per the multi-disciplinary team decision do not require immediate radiotherapy, surgery or standard systematic chemotherapy.

Melanoma brain metastases study arm of the expansion phase:

Patients with pathologically confirmed diagnosis of advanced, recurrent melanoma with at least one progressive and/or new metastatic brain lesion that are refractory to standard therapy or for whom no standard therapy exist. Stable or decreasing dosages of steroids (e.g. dexamethasone) for 7 days prior to baseline MRI and/or use of non-enzyme inducing anti-epileptic drugs are allowed.

Or

Patients with pathologically confirmed diagnosis of advanced melanoma with newly diagnosed, untreated, brain metastases and controlled extracranial disease which per the multi-disciplinary team decision do not require immediate radiotherapy, surgery or standard systematic chemotherapy.

Recurrent malignant glioma study arm of the expansion phase:

7 patients with histologically proven glioma grade IV, which is progressive following first line treatment with surgery or biopsy followed by fractionated radiotherapy with concurrent temozolomide-containing chemotherapy.

and

7 patients with recurrent histologically confirmed malignant (WHO grade III and IV) glioma or histologically confirmed low-grade (WHO grade II) glioma with radiographic evidence of malignant transformation by MRI, that are refractory to standard therapy, or for whom no standard therapy exists or do not require immediate standard therapy per the multi-disciplinary team decision. Patients in both groups should have stable or decreasing dosage of steroids (e.g. dexamethasone) for a minimum of 7 days prior to baseline MRI. Non-enzyme inducing anti-epileptic drugs are allowed
