Inclusion Criteria:

• Patient must give written informed consent before registration.
• For Part A: Histologically or cytologically confirmed diagnosis of advanced solid tumors that have progressed despite standard therapy. No more than two prior lines of chemotherapy for advanced disease.
• For Part B: Histologically or cytologically confirmed diagnosis of advanced ovarian cancer. Prior chemotherapy must have contained a platinum and a taxane at some point. Any prior taxane therapy must have been administered on a 3-week schedule. A maximum of 2 prior chemotherapy lines for advanced disease will be permitted. Patients must be refractory (PD during chemotherapy) or resistant (PD within 6 months of completing chemotherapy) to their last platinum-containing chemotherapy regimen.
• For Part C: Histologically or cytologically confirmed diagnosis of advanced ovarian cancer. Prior chemotherapy must have contained a platinum and a taxane at some point. Prior taxane therapy must have been administered on weekly schedule and must be followed by a wash-out period of at least 6 months. A maximum of 2 prior chemotherapy lines for advanced disease will be permitted. Patients must be refractory (PD during chemotherapy) or resistant (PD within 6 months of completing chemotherapy) to their last platinum-containing chemotherapy regimen.
• For Parts B and C, patients must have measurable disease according to RECIST v1.1 Radiological evaluations to be performed within 4 weeks before registration.
