The NCI's Division of Cancer Prevention (DCP) conducts and supports research to determine a person's risk of cancer and to find ways to reduce the risk. This knowledge is critical to making progress against cancer because risk varies over the lifespan as genetic and epigenetic changes can transform healthy tissue into invasive cancer. With an overall goal to detect such changes and intervene early in the cancer process to prevent symptomatic disease and death, DCP funds and provides administrative support to clinical and laboratory researchers, community and multidisciplinary teams, and collaborative scientific networks.About Ductal Carcinoma in Situ Ductal Carcinoma in Situ (DUK-tul KAR-sih-NOH-muh in SY-too), or DCIS, is defined by the NCI as a noninvasive condition in which abnormal cells are found in the lining of a breast duct, and is the most common type of breast cancer. The abnormal cells have not spread outside the duct to other tissues in the breast. In some cases, DCIS may become invasive cancer and spread to other tissues, and at this time, there is no way to know which lesions could become invasive. Current treatment options for DCIS include breast-conserving surgery and radiation therapy with or without tamoxifen, breast-conserving surgery without radiation therapy, or total mastectomy with or without tamoxifen. According to the American Cancer Society, in 2014 there were an estimated 51,933 diagnoses of ductal carcinoma in situ. About NeuVax™ (nelipepimut-S) NeuVax™ (nelipepimut-S) is a first-in-class, HER2-directed cancer immunotherapy under evaluation to prevent breast cancer recurrence after standard of care treatment in the adjuvant setting. It is the immunodominant peptide derived from the extracellular domain of the HER2 protein, a well-established target for therapeutic intervention in breast carcinoma. NeuVax has been shown to bind to HLA-A2 and A3, as well as HLA-A24 and A26 molecules. The nelipepimut-S sequence stimulates specific CD8+ cytotoxic T lymphocytes (CTLs) following binding to specific HLA molecules on antigen presenting cells (APC). These activated specific CTLs recognize, neutralize and destroy, through cell lysis, HER2 expressing cancer cells, including occult cancer cells and micrometastatic foci. The nelipepimut-S immune response can also generate CTLs to other immunogenic peptides through inter- and intra-antigenic epitope spreading.
NeuVax is currently in an international, Phase 3 PRESENT ( Prevention of Recurrence in Early- Stage, Node-Positive Breast Cancer with Low to Intermediate HER2 Expression with NeuVax Treatment) study under a Special Protocol Assessment (SPA) granted by the U.S. Food and Drug Administration (FDA). Additional information on the PRESENT trial can be found at www.neuvax.com (clinicaltrials.gov identifier: NCT01479244). Galena has two additional breast cancer studies ongoing with NeuVax in combination with trastuzumab (Herceptin®; Genentech/Roche): a Phase 2b trial in node positive and triple negative HER2 IHC 1+/2+ (clinicaltrials.gov identifier: NCT01570036); and, a Phase 2 trial in neoadjuvantly treated node positive and negative HER2 IHC 3+ patients not achieving a pathological complete response (pCR) or adjuvantly treated node positive HER2 IHC 3+ patients (clinicaltrials.gov identifier: NCT02297698).About Galena Biopharma Galena Biopharma, Inc.
