• To evaluate the safety of secondary chemotherapy induced thrombocytopenia prophylaxis with romiplostim in ovarian cancer subjects receiving myelosuppressive chemotherapy. • To show advantageous results in the verum group with respect to other parameters related to platelets and supportive requirements.

Coli-derived product or any additives •Inability to comply with the protocol or missing written informed consent •Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and followup schedule; those conditions should be discussed with the subject before registration in the trial. •Accommodation in an institution due to official or legal orders (§40 p. 1 No. 4 AMG)
