A phase Ib, dose escalation, multiple dose trial with HuMax-IL8 in patients with metastatic or unresectable, locally advanced malignant solid tumors.

All human subjects with a diagnosis of incurable solid tumors are eligible for the dose-escalation phase of this study. This study consists of two phases, the dose-escalation phase and the expansion phase. Subjects will be treated with the study treatment until any off-treatment criteria are met. The safety and efficacy will be assessed until the end of treatment or for a maximum of 52 weeks. In addition, a separate visit will be performed at the time of disease progression if the patient has a progression between end of treatment and 52 weeks. The patients will be followed up for overall survival until the study closure. The study will be closed when all enrolled patients have been followed up for at least 52 weeks or have died.

Inclusion Criteria:

• Subjects must have metastatic or unresectable locally advanced malignant solid tumor.
• Patients may have measurable or non-measurable but evaluable disease.
• Patients with surgically resected metastatic disease at high risk of relapse are also eligible.
• Patients must have completed or had disease progression on at least one prior line of disease-appropriate therapy for metastatic disease, or not be candidates for therapy of proven efficacy for their disease.
• Patients must have recovered (grade 1 or baseline) from any clinically significant toxicity associated with prior therapy
