Exploratory Phase 2 Study of Farletuzumab in Resectable Non-functioning Pituitary Adenoma

Non-functioning pituitary adenomas are the most frequent type of pituitary tumors, defined
by the lack of hormonal overproduction from the tumor. Non-functioning macroadenomas are >
1 cm in size that can cause progressive visual loss, headaches, and symptoms of pituitary
dysfunction (hypopituitarism and/or hyperprolactinemia). Initial treatment for these type
of tumors is trans sphenoidal surgical resection. In cases where the outcome is incomplete
surgical resection of the tumor, repeat surgery and external beam radiation therapy may be
performed. Previous clinical work suggests there may be a role for a folate receptor in the
treatment of non-secretory, pituitary adenomas. MORAb-003 is a monoclonal antibody that has
the potential to be an effective agent against resectable, non-functioning pituitary
adenomas. MORAb-003 has been shown to be well tolerated. This study allows the opportunity
to determine if therapy with farletuzumab is effective and safe.

Inclusion Criteria:

- Males and females >18 years old

- Diagnosis of non-functional pituitary adenoma

- Able and willing to undergo surgical resection of the pituitary tumor

- Significant medical conditions must be well-controlled and stable for at least 30
days prior to signing the informed consent form

Exclusion Criteria:

- Presence of clinically significant pituitary apoplexy

- Presence of hormone-secreting adenomas

- Presence of compressive optic neuropathy due to pituitary tumor

- No prior surgical, medical, or radiation therapy in the last 6 months
