  • A Controlled Study of the Effectiveness of Oregovomab (Antibody) Plus Chemotherapy in Advanced Ovarian Cancer Not Recruiting

    This is a Phase 2 randomized study with two treatment arms to compare the effectiveness of oregovomab (a murine monoclonal antibody directed against cancer antigen 125 (CA125)) when combined with first-line chemotherapy (carboplatin and paclitaxel) to first-line chemotherapy (carboplatin and paclitaxel) alone in female patients with advanced ovarian cancer. This study is to confirm previous results that showed oregovomab was able to help the body to produce an immune response to CA125 (a target that has been identified on ovarian cancer cells) in patients with stage III-IV ovarian cancer when they were receiving chemotherapy for their disease. The primary aim of the study is to see how well these patients with advanced ovarian cancer make an immune response to CA125 by using a specific test (enzyme-linked immunospot (ELISPOT) assay) of the patient's blood. The study will also look at the side effects of the oregovomab, other immune response parameters, how well the patients respond to the treatment of their disease (how long it takes to show that their disease has progressed and how long these patients survive overall).

  • HE4 (WFDC2) gene overexpression promotes ovarian tumor growth SCIENTIFIC REPORTS Moore, R. G., Hill, E. K., Horan, T., Yano, N., Kim, K., MacLaughlan, S., Lambert-Messerlian, G., Tseng, Y. D., Padbury, J. F., Miller, M. C., Lange, T. S., Singh, R. K. 2014; 4


    Selective overexpression of Human epididymal secretory protein E4 (HE4) points to a role in ovarian cancer tumorigenesis but little is known about the role the HE4 gene or the gene product plays. Here we show that elevated HE4 serum levels correlate with chemoresistance and decreased survival rates in EOC patients. HE4 overexpression promoted xenograft tumor growth and chemoresistance against cisplatin in an animal model resulting in reduced survival rates. HE4 displayed responses to tumor microenvironment constituents and presented increased expression as well as nuclear translocation upon EGF, VEGF and Insulin treatment and nucleolar localization with Insulin treatment. HE4 interacts with EGFR, IGF1R, and transcription factor HIF1?. Constructs of antisense phosphorothio-oligonucleotides targeting HE4 arrested tumor growth in nude mice. Collectively these findings implicate increased HE4 expression as a molecular factor in ovarian cancer tumorigenesis. Selective targeting directed towards the HE4 protein demonstrates therapeutic benefits for the treatment of ovarian cancer.

  • PT19c, Another Nonhypercalcemic Vitamin D2 Derivative, Demonstrates Antitumor Efficacy in Epithelial Ovarian and Endometrial Cancer Models. Genes & cancer Kawar, N., MacLaughlan, S., Horan, T. C., Uzun, A., Lange, T. S., Kim, K. K., Hopson, R., Singh, A. P., Sidhu, P. S., Glass, K. A., Shaw, S., Padbury, J. F., Vorsa, N., Arnold, L. A., Moore, R. G., Brard, L., Singh, R. K. 2013; 4 (11-12): 524-534


    Hypercalcemia remains a major impediment to the clinical use of vitamin D in cancer treatment. Approaches to remove hypercalcemia and development of nonhypercalcemic agents can lead to the development of vitamin D-based therapies for treatment of various cancers. In this report, in vitro and in vivo anticancer efficacy, safety, and details of vitamin D receptor (VDR) interactions of PT19c, a novel nonhypercalcemic vitamin D derived anticancer agent, are described. PT19c was synthesized by bromoacetylation of PTAD-ergocalciferol adduct. Broader growth inhibitory potential of PT19c was evaluated in a panel of chemoresistant breast, renal, ovarian, lung, colon, leukemia, prostate, melanoma, and central nervous system cancers cell line types of NCI60 cell line panel. Interactions of PT19c with VDR were determined by a VDR transactivation assay in a VDR overexpressing VDR-UAS-bla-HEK293 cells, in vitro VDR-coregulator binding, and molecular docking with VDR-ligand binding domain (VDR-LBD) in comparison with calcitriol. Acute toxicity of PT19c was determined in nontumored mice. In vivo antitumor efficacy of PT19c was determined via ovarian and endometrial cancer xenograft experiments. Effect of PT19c on actin filament organization and focal adhesion formation was examined by microscopy. PT19c treatment inhibited growth of chemoresistant NCI60 cell lines (log10GI50 ~ -4.05 to -6.73). PT19c (10 mg/kg, 35 days) reduced growth of ovarian and endometrial xenograft tumor without hypercalcemia. PT19c exerted no acute toxicity up to 400 mg/kg (QDx1) in animals. PT19c showed weak VDR antagonism, lack of VDR binding, and inverted spatial accommodation in VDR-LBD. PT19c caused actin filament dysfunction and inhibited focal adhesion in SKOV-3 cells. PT19c is a VDR independent nonhypercalcemic vitamin D-derived agent that showed noteworthy safety and efficacy in ovarian and endometrial cancer animal models and inhibited actin organization and focal adhesion in ovarian cancer cells.

  • Identification of Ovarian Cancer Metastatic miRNAs PLOS ONE Vang, S., Wu, H., Fischer, A., Miller, D. H., MacLaughlan, S., Douglass, E., Steinhoff, M., Collins, C., Smith, P. J., Brard, L., Brodsky, A. S. 2013; 8 (3)


    Serous epithelial ovarian cancer (EOC) patients often succumb to aggressive metastatic disease, yet little is known about the behavior and genetics of ovarian cancer metastasis. Here, we aim to understand how omental metastases differ from primary tumors and how these differences may influence chemotherapy. We analyzed the miRNA expression profiles of primary EOC tumors and their respective omental metastases from 9 patients using miRNA Taqman qPCR arrays. We find 17 miRNAs with differential expression in omental lesions compared to primary tumors. miR-21, miR-150, and miR-146a have low expression in most primary tumors with significantly increased expression in omental lesions, with concomitant decreased expression of predicted mRNA targets based on mRNA expression. We find that miR-150 and miR-146a mediate spheroid size. Both miR-146a and miR-150 increase the number of residual surviving cells by 2-4 fold when challenged with lethal cisplatin concentrations. These observations suggest that at least two of the miRNAs, miR-146a and miR-150, up-regulated in omental lesions, stimulate survival and increase drug tolerance. Our observations suggest that cancer cells in omental tumors express key miRNAs differently than primary tumors, and that at least some of these microRNAs may be critical regulators of the emergence of drug resistant disease.

  • Randomised controlled trial comparing hypnotherapy versus gabapentin for the treatment of hot flashes in breast cancer survivors: a pilot study. BMJ open Maclaughlan David, S., Salzillo, S., Bowe, P., Scuncio, S., Malit, B., Raker, C., Gass, J. S., Granai, C. O., Dizon, D. S. 2013; 3 (9)


    To compare the efficacy of hypnotherapy versus gabapentin for the treatment of hot flashes in breast cancer survivors, and to evaluate the feasibility of conducting a clinical trial comparing a drug with a complementary or alternative method (CAM).Prospective randomised trial.Breast health centre of a tertiary care centre.15 women with a personal history of breast cancer or an increased risk of breast cancer who reported at least one daily hot flash.Gabapentin 900 mg daily in three divided doses (control) compared with standardised hypnotherapy. Participation lasted 8 weeks.The primary endpoints were the number of daily hot flashes and hot flash severity score (HFSS). The secondary endpoint was the Hot Flash Related Daily Interference Scale (HFRDIS).27 women were randomised and 15 (56%) were considered evaluable for the primary endpoint (n=8 gabapentin, n=7 hypnotherapy). The median number of daily hot flashes at enrolment was 4.5 in the gabapentin arm and 5 in the hypnotherapy arm. HFSS scores were 7.5 in the gabapentin arm and 10 in the hypnotherapy arm. After 8 weeks, the median number of daily hot flashes was reduced by 33.3% in the gabapentin arm and by 80% in the hypnotherapy arm. The median HFSS was reduced by 33.3% in the gabapentin arm and by 85% in the hypnotherapy arm. HFRDIS scores improved by 51.6% in the gabapentin group and by 55.2% in the hypnotherapy group. There were no statistically significant differences between groups.Hypnotherapy and gabapentin demonstrate efficacy in improving hot flashes. A definitive trial evaluating traditional interventions against CAM methods is feasible, but not without challenges. Further studies aimed at defining evidence-based recommendations for CAM are (NCT00711529).
