The purpose of the study is to determine the safety and tolerability of GLPG0187 administered through continuous intravenous infusion and to explore its preliminary clinical efficacy in patients with solid tumors.

Patients with pathologically confirmed diagnosis of advanced, recurrent, or metastatic cancer and who are refractory to standard therapy or for whom no standard therapy exists will first receive a one-hour infusion of a defined dose of GLPG0187. If well tolerated, one week later a three-week continuous infusion is started. If according to the investigator a subject has a clinical benefit from treatment with GLPG0187, the treatment cycle may be repeated until disease progression, Dose Limiting Toxicity (DLT), or the patient chooses to stop or cannot/will not comply with study procedures.

Throughout treatment, safety and tolerability will be monitored. Within one patient, a fixed dose (infusion rate) will be used. If at a given dose-level sufficient patients have been treated without reaching DLT, the dose for the next group of patients will be increased. This can be repeated until DLT is established, or the scheduled maximum dosage is reached.

Inclusion Criteria:

• Pathologically confirmed diagnosis of advanced, recurrent, or metastatic cancer who are refractory to standard therapy or for whom no standard therapy exist.

  • Known hypersensitivity to any of the study drugs or excipients.
  • Evidence of any other medical conditions (such as psychiatric illness, infectious diseases, physical examination or laboratory findings) that may interfere with the planned treatment, affect subject compliance or place the subject at high risk from treatment-related complications.
