Inclusion Criteria:

Histological or cytological documentation of MPM or NSCLC and evidence of EGFR expression in tumour tissue.

Progression during or following the administration of standard 1st, 2nd or 3rd line therapy regimens.

Patient must have at least one measurable lesion according to the RECIST criteria version 1.1 for NSCLC and modified RECIST criteria for MPM

Male or female patients at least 18 years of age. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

Life expectancy of at least 3 months.

Women of childbearing potential and men must agree to use adequate contraception from the time of signing of the informed consent form until at least 3 months after the last study drug administration.

Total bilirubin < 1.5 x the upper limit of normal (ULN) ALT and AST < 2.5 x ULN Amylase < 1.5 x ULN Serum creatinine < 1.5 x ULN GFR > 60 ml/min/m2 INR/PTT < 1.5 x ULN (patients who are therapeutically treated with an agent such as warfarin or heparin will be allowed to participate provided that no prior evidence of underlying abnormality in coagulation parameters exists. Close monitoring with at least weekly evaluations will be performed until INR/APTT is stable (prior to administering the first dose)).

Platelet count > 100.000 and < 800.000, Hemoglobin (Hb) > 9 g/dl, Absolute Neutrophil count (ANC) > 1500/mm3. Alkaline phosphatase limit < 2.5 x ULN.

Exclusion Criteria:

Previous phase I drug treatment for the current diagnosis. Previous or concurrent cancer that is distinct in primary site or histology from MPM or NSCLC within 10 years from the date of screening EXCEPT for curatively treated cervical cancer in situ, non-melanoma skin cancer and superficial bladder tumours (Ta, Tis and T1).

Presence of Salmonella antibodies. Herbal supplements (such as St John's Wort), nutritional supplements and also (multi)-vitamins taken within the last 30 days prior to dosing on Day 1 (and continued use, if appropriate), must be reviewed and approved by the local investigator.

Major surgical procedures in the last four weeks. Pregnancy or breast-feeding. Congestive heart failure > New York Heart Association (NYHA) class 2. Unstable angina (angina at rest) or new-onset angina (< 3 months). Myocardial infarction less than 6 months before eligibility screening.

Cardiac arrhythmias requiring anti-arrhythmic therapy (beta-blockers or digoxin are permitted).

Uncontrolled hypertension (Systolic blood pressure > 150 mmHg or diastolic pressure > 90 mm Hg despite optimal medical management).

Arterial or venous thrombotic or embolic events such as cerebrovascular accident (including Transient Ischemic Attacks), deep vein thrombosis or pulmonary embolism within 6 months before the screening radiographic studies.

Ongoing infection > grade 2 NCI-CTCAE version 4.0 HIV infection. Chronic hepatitis B or C. Patients with a seizure disorder requiring medication. Symptomatic brain metastasis(es). The patient must not be undergoing acute steroid therapy or steroid tapering (Chronic steroid therapy is acceptable provided that the dose is stable for one month prior to and following screening radiographic studies).

Patients with a history of bleeding diathesis: Any hemorrhage or bleeding event of CTCAE Grade 3 within 4 weeks of the proposed start of study medication.

Renal failure requiring hemo-or peritoneal dialysis. Substance abuse, medical, psychological or social conditions that in the opinion of the investigator may interfere with the patient's participation in the study or evaluation of the study results.

Known hypersensitivity to bacterial proteins. Any medical condition that is unstable or could jeopardize the safety of the patient and his/her compliance in the study.

Unresolved toxicity higher than NCI-CTCAE (version 4.0) Grade 2 attributed to any prior therapy/procedure excluding alopecia.
