Serious illness or concomitant non-oncological disease such as neurologic-, psychiatric-, infectious disease or active ulcers (gastro-intestinal tract, skin) or laboratory abnormality that may increase the risk associated with trial participation or investigational drug administration and in the judgment of the investigator would make the patient inappropriate for entry into the trial. 21.
