About GALE-301 (Folate Binding Protein (FBP) vaccine)

GALE-301 (Folate Binding Protein (FBP)) cancer immunotherapy targets FBP, a well-validated therapeutic target, which is highly over-expressed in breast, ovarian and endometrial cancers. FBP is the source of immunogenic peptides that can stimulate cytotoxic T lymphocytes (CTLs) to recognize and destroy presenting FBP-expressing cancer cells. The FBP vaccine consists of the FBP peptide(s) combined with the immune adjuvant, granulocyte macrophage-colony stimulating factor (GM-CSF).   Galena's FBP vaccine is currently in a Phase 1/2 trial in two gynecological cancers: ovarian and endometrial adenocarcinomas.

About Ovarian/Endometrial Cancers

Ovarian cancer occurs in more than 22,000 patients per year in the U.S. and is the most lethal gynecologic cancer. Despite the incidence of ovarian cancer being only approximately 20% of that of breast cancer, the number of patients that die from ovarian cancer is nearly 50% of that of breast cancer. Due to the lack of specific symptoms, the majority of ovarian cancer patients are diagnosed at later stages of the disease. These patients have their tumors routinely surgically debulked to minimal residual disease, and then are treated with platinum- and/or taxane-based chemotherapy. While most patients respond to this treatment regimen and become clinically free-of-disease, the majority of these patients will relapse, and once the disease recurs, the treatment options and successes drop dramatically.

Endometrial cancer is the most common gynecologic cancer and occurs in more than 46,000 women with more than 8,000 deaths in the U.S. annually. There are two basic types of endometrial cancer: endometrioid and papillary serous. The latter has a much more aggressive clinical course and the majority of these patients will die of this form of the disease.
