Key Exclusion Criteria:

• Prior treatment with any agent targeting Folate Receptor Alpha.

• Active central nervous system metastasis.

• Persistent toxicities from previous systemic anti-neoplastic treatments of Grade >1.

• Systemic anti-neoplastic therapy within five half-lives or 21 days, whichever is shorter, prior to the first dose of the study drug.

• Radiotherapy to lung field at a total radiation dose of >= 20 Gy within 6 months, wide-field radiotherapy (>30% of marrow-bearing bones) within 28 days, or focal radiation for analgesic purpose or for lytic lesions at risk of fracture within 14 days prior to the first dose of the study drug, or no recovery from side effects of such intervention.

• Major surgery (not including placement of vascular access device or tumor biopsies) within 28 days prior to the first dose of the study drug, or no recovery from side effects of such intervention.

• Prior allogeneic or autologous bone marrow transplantation.

• Significant cardiac or lung disease, active or chronic ocular disorders, thromboembolic or cerebrovascular events within 6 months prior to the first dose of the study drug, acute and/or clinically significant bacterial, fungal, or viral infection.
