2014 ASCO: Phase 1 testing of VS-6063 (defactinib; targeting cancer stem cells) + paclitaxel (Taxol) shows early signs of clinical activity (64% clinical benefit rate) in ovarian cancer patients......- http://phx.corporate-ir.net/phoenix...
“These data continue to show that the combination of cancer stem cell-targeting agent VS-6063 and paclitaxel is well tolerated, with no unexpected toxicity or worsening of the well understood side effects of paclitaxel, and support the further study of this combination in the clinic,” said Dr. Joanna Horobin, Verastem Chief Medical Officer. “In addition to the demonstration of safety, we continue to see interesting signs of early clinical activity where 14 of 22 (64%) patients enrolled in this study achieved a best overall response of at least stable disease including two partial responses and two complete responses to date.” - Libby's H*O*P*E*

Identifying Lynch syndrome in patients with ovarian carcinoma: the significance of tumor subtype... ... [Adv Anat Pathol. 2013] - PubMed - NCBI - http://www.ncbi.nlm.nih.gov/pubmed...
In spite of contradictory results, likely reflective of differences in study design, sample size and methodology, a recurring observation is the overrepresentation of "endometriosis-associated tumors," namely, endometrioid and clear cell subtypes, in the group of ovarian tumors with MMR deficiency. - Libby's H*O*P*E*

Scientists from USC and NYU design a molecule that blocks cancer growth in mice - http://www.eurekalert.org/pub_rel...
Protein–protein interactions are attractive targets for drug design due to their fundamental role in biological function. However, small molecules that selectively target the intended interactions have been difficult to access using traditional drug discovery approaches. We show that compounds that reproduce key functionality at the interface between transcription factor hypoxia-inducible factor 1α (HIF1α) and coactivator p300 (or CREB binding protein, CBP) can inhibit expression of a multitude of genes under hypoxic environments. The designed inhibitors target the chosen protein–protein interaction in a predictable manner and reduce tumor growth in mouse xenograft models. - Libby's H*O*P*E*

Molecular Genetics of Clear-Cell Renal Cell Carcinoma - http://jco.ascopubs.org/content...
At least one study has found a genomic similiarity (albeit not identifical) between renal (kidney) clear cell cancer and ovarian clear cell cancer. This finding suggests that targeted therapies used to treat RCCC could also be used to treat OCCC. - Libby's H*O*P*E*

Circulating proteolytic signatures of chemotherapy-induced cell death in humans discovered by N-terminal labeling - http://www.pnas.org/content...
Many chemotherapeutics function by inducing cellular apoptosis, or programmed cell death, in tumor cells. Here, using a unique enzymatically driven technology, we find that numerous protein fragments are released into the bloodstream from apoptotic cells within hours after chemotherapy. These circulating signatures of cell death, if confidently assigned to tumor cells, may form the foundation for entirely novel, rapid, and inexpensive biomarkers of chemotherapeutic efficacy. Diagnostic tests to rapidly assess cell death after treatment could serve an important role in management for many cancers. - Libby's H*O*P*E*

Adoptive T-Cell Immunotherapy Based on Mutation-Specific CD4+ T Cells in a Patient with Epithelial (Bile Duct) Cancer - http://www.sciencemag.org/content...
Malignant tumors harbor genetic alterations. Recently, adoptive T cell therapies have taken advantage of this: T cells specific for mutations in tumors are infused into patients to generate an antitumor immune response. Although therapeutic benefit has been seen for melanomas, effectiveness against more common epithelial tumors is unclear. Using whole-exome sequencing, Tran et al. (p. 641) identified tumor-infiltrating CD4+ T cells specific for a mutated antigen expressed by a tumor from a patient with metastatic cholangiocarcinoma. Infusion of this patient with an expanded-population, mutation-specific T cell resulted in tumor regression and stabilization of disease. - Libby's H*O*P*E*

2013 AACR-NCI-EORTC Mtg: Verastem's Results Support Continued Development of VS-6063 (defactinib)(FAK inhibitor) Across Multiple Tumor Types, including Ovarian .....http://www.businesswire.com/news...
Results from the Phase 1 dose escalation portion of the study were presented. Six patients with advanced or refractory ovarian cancer, all of whom had prior taxane exposure and were platinum resistant, were enrolled. Two patients demonstrated significant decreases, or normalization, of CA-125, a marker that becomes elevated with disease progression in ovarian cancer. One patient in the VS-6063 200mg BID cohort experienced an ongoing complete response as confirmed by Response Evaluation Criteria in Solid Tumors (RECIST) with repeated radiologic scans and a second patient in the VS-6063 400mg BID cohort continues to experience prolonged stabilization of her disease. Patient recruitment remains ongoing in the expansion Phase 1b open-label, multicenter portion of the study, where Verastem expects to enroll a total of approximately 15 patients at three U.S. locations. - Libby's H*O*P*E*

Data From Phase I Clinical Trial Of Mitochondrial Inhibitor Drug ME-344 Reveals 35% Disease Control Rate in Refractory Solid Tumors - http://investor.meipharma.com/2013-10...
As reported in the abstract of the presentation, eight of the 23 patients evaluable for efficacy (35%) achieved disease control, including one confirmed partial response (PR) in a patient with refractory small cell lung cancer (duration 52+ weeks) and seven patients with prolonged stable disease (SD) ranging from 8 to 40+ weeks. The maximum tolerated dose was established at 10 mg kg delivered on a weekly schedule. Dose limiting toxicity of Grade 3 neuropathy was observed at 15 mg/kg and 20 mg/kg. Based on these findings, MEI Pharma is actively preparing for a phase Ib clinical trial of ME-344 in combination with Hycamtin (topotecan) in small cell lung cancer and ovarian cancer, which it expects to initiate during the second quarter of 2014.” - Libby's H*O*P*E*

Current standards of care for chemotherapy of optimally cytoreduced advanced epithelial ovarian cancer - http://www.sciencedirect.com/science...
Platinum-taxane chemotherapy remains the standard of care for the primary treatment of optimally cytoreduced advanced epithelial ovarian cancer. Primary intraperitoneal cisplatin-based chemotherapy has been shown to improve survival in the setting of optimal residual advanced ovarian cancer. The role of bevacizumab in the primary anti-neoplastic drug management of optimal residual advanced ovarian cancer remains to be defined. - Libby's H*O*P*E*

Surgical outcomes and national comprehensive cancer network compliance in advanced ovarian cancer surgery in a low volume military treatment facility - http://www.sciencedirect.com/science...
NCCN compliant treatment and survival are reportedly improved at high volume hospitals, arguing for centralization of care. The low volume hospital achieved 85% NCCN treatment compliance, 73% optimal surgical cytoreduction, and 37 month overall survival rates. Hospital volume alone is not a reliable metric for quality patient care. - Libby's H*O*P*E*

Overexpression of c-Abl predicts unfavorable outcome in epithelial ovarian cancer - http://www.sciencedirect.com/science...
Study on the association between c-Abl overexpression and metastasis of EOC is rare. Up-regulated c-Abl expression is associated with an unfavorable prognosis and is an independent prognostic factor for EOC. c-Abl may be a potential effective prognostic marker for EOC. - Libby's H*O*P*E*

Pre-operative imaging with CA125 is a poor predictor for granulosa cell tumors - http://www.sciencedirect.com/science...
Granulosa cell tumors are almost exclusively complex and are most frequently greater than 10 cm. There was a near equal distribution of granulosa cell tumors with a CA125 greater than or less than 35. If complexity and a CA125 level > 35 are used to predict GCTs, we will frequently fail to predict them. - Libby's H*O*P*E*

Diagnostic performance of the biomarkers HE4 and CA125 in type I and type II epithelial ovarian cancer - http://www.sciencedirect.com/science...
With HE4 and CA125 we can diagnose the aggressive type II EOC at all stages and ages most correctly. The diagnostic safety for the dual markers HE4 and CA125 is not acceptable in early stage type I EOC. Our results support that EOC should be looked upon as several different diseases. - Libby's H*O*P*E*

ABCB1 (MDR1) polymorphisms and ovarian cancer progression and survival: A comprehensive analysis from the Ovarian Cancer Association Consortium and The Cancer Genome Atlas - http://www.sciencedirect.com/science...
ABCB1 C1236T (rs1128503) was marginally associated with improved overall survival in 4,616 invasive ovarian cancer patients regardless of chemotherapy. Analysis of an additional 1,562 SNPs flanking ABCB1 in ~ 3000 invasive ovarian cancer patients yielded no new signals. Analysis of ABCB1 expression in 143 ovarian tumors showed that ABCB1 expression may worsen prognosis in sub-optimally debulked patients. - Libby's H*O*P*E*

BMN 673 monotherapy (PARP 1/2 inhibitor) makes splash in BRCA-mutated ovarian, breast cancer : OBGYN News - http://www.obgynnews.com/single-...
Among 25 ovarian cancer patients evaluable by RECIST, 1 patient had a complete response, 10 had partial responses, and 4 had stable disease lasting 24 weeks or more, Dr. Ramanathan reported. Responses were seen in 17 of 22 platinum-sensitive patients. "Platinum sensitivity may be important in identifying patients sensitive to BMN 673," he said. Cancer antigen 125 levels evaluable in 27 ovarian cancer patients dropped by more than 50% in 19 (70%) and returned to the normal range in 9. - Libby's H*O*P*E*
