Ongoing Vaccine Trials in Breast and Ovarian Cancer

To date, sipuleucel-T remains the first and only FDA-approved cancer treatment vaccine on the market and is used for some men with metastatic prostate cancer.3 Best estimates of clinical availability of a vaccine to treat breast and ovarian cancer range from 5 to 10 years.

Genentech, Inc., and Galena Biopharma are enrolling patients with HER2-positive breast cancer for 2 phase 2 trials (ClinicalTrials.gov Identifiers: NCT02297698 and NCT01570036) of the nelipepimut-S vaccine with trastuzumab vs trastuzumab plus GM-CSF alone in to prevent recurrence in the adjuvant setting.4

The National Cancer Institute is conducting a phase 2 study (ClinicalTrials.gov Identifier: NCT02636582) of nelipepimut-S plus GM-CSF in women with DCIS.

The National Cancer Institute is recruiting for a phase 1 trial (ClinicalTrials.gov Identifier: NCT01730118) of an adenoviral transduced autologous DC vaccine expressing human HER2/neu (AdHER2/neu) in adults with tumors — including breast, adenocarcinomas, and metastatic solid tumors characterized by HER2/neu expression — with 1 to 3-positive HER2/neu expression.

The University of Connecticut also recently announced open accrual of patients for “the world’s first personalized genomics-driven ovarian cancer vaccine clinical trial” using OncoImmune, which will be individualized for each patient.5

The phase 1 study (ClinicalTrials.gov Identifier: NCT02933073) will enroll up to 15 women with stage III/IV ovarian cancer in clinical remission after standard of care, with monitoring up to 5 years post-vaccination.
