Breast cancer antiestrogen resistance 3-p130(Cas) interactions promote adhesion disassembly and invasion in breast cancer cells.

Adhesion turnover is critical for cell motility and invasion. We previously demonstrated that the adaptor molecule breast cancer antiestrogen resistance 3 (BCAR3) promotes adhesion disassembly and breast tumor cell invasion. One of two established binding partners of BCAR3 is the adaptor molecule, p130(Cas). In this study, we sought to determine whether signaling through the BCAR3-Cas complex was responsible for the cellular functions of BCAR3. We show that the entire pool of BCAR3 is in complex with Cas in invasive breast tumor cells and that these proteins colocalize in dynamic cellular adhesions. Although accumulation of BCAR3 in adhesions did not require Cas binding, a direct interaction between BCAR3 and Cas was necessary for efficient dissociation of BCAR3 from adhesions. The dissociation rates of Cas and two other adhesion molecules, α-actinin and talin, were also significantly slower in the presence of a Cas-binding mutant of BCAR3, suggesting that turnover of the entire adhesion complex was delayed under these conditions. As was the case for adhesion turnover, BCAR3-Cas interactions were found to be important for BCAR3-mediated breast tumor cell chemotaxis toward serum and invasion in Matrigel. Previous work demonstrated that BCAR3 is a potent activator of Rac1, which in turn is an important regulator of adhesion dynamics and invasion. However, in contrast to wild-type BCAR3, ectopic expression of the Cas-binding mutant of BCAR3 failed to induce Rac1 activity in breast cancer cells. Together, these data show that the ability of BCAR3 to promote adhesion disassembly, tumor cell migration and invasion, and Rac1 activity is dependent on its ability to bind to Cas. The activity of BCAR3-Cas complexes as a functional unit in breast cancer is further supported by the co-expression of these molecules in multiple subtypes of human breast tumors.Oncogene advance online publication, 25 April 2016; doi:10.1038/onc.2016.123.

Thromboelastometric Monitoring of the Hemostatic Effect of Platelet Concentrates Transfusion in Thrombocytopenic Children Undergoing Chemotherapy.

Prophylactic platelet concentrates transfusion represents a therapeutic choice in patients with chemotherapy-induced thrombocytopenia. This prospective, non-interventional study evaluated the effects of platelet concentrates transfusion on thromboelastometric parameters of platelet function in 36 transfusion occasions for 11 thrombocytopenic children undergoing chemotherapy. Pre- and posttransfusion (1-2 hours) blood samples were analyzed using standard coagulation tests and thromboelastometry (ROTEM) measurements (EXTEM and FIBTEM tests). Platelet component of the clot was calculated based on the EXTEM and FIBTEM maximum clot elasticity (MCE) results. After transfusion, mean platelet count increased from 16.5 × 10(9)/L to 43.0 × 10(9)/L (P < .001) and platelet component increased from 34.1 to 73.0 (P < .001). Statistically significant increases for posttransfusion EXTEM parameters A10, A20, and maximum clot firmness (MCF) were observed compared to pretransfusion values (P < .001). The EXTEM α-angle values increased posttransfusion (P < .05). The FIBTEM measurements were comparable pre- and posttransfusion. The study showed that platelet concentrates transfusion in thrombocytopenic children undergoing chemotherapy improves platelet-related coagulation pattern.

"We are off to a strong start in 2016, with first quarter results exceeding our expectations," said José (Joe) E. Almeida, chairman and chief executive officer. "Our new strategic framework focused on portfolio optimization, operational excellence and capital allocation is driving improved performance throughout the organization and is reflected in our increased financial outlook for the year. We are confident our strategy positions the company for sustainable growth and value creation for all our stakeholders."

During the quarter, Baxter achieved a number of operational, pipeline and commercial milestones in support of its strategy to accelerate profitable growth, including:

U.S. launch of ready-to-use VANCOMYCIN injection in 0.9% Sodium Chloride (Normal Saline) in 500 mg, 750 mg and 1 gram presentations. Baxter is the only manufacturer to offer VANCOMYCIN in a premixed presentation, which uses the company’s proprietary frozen GALAXY container technology. With this launch, Baxter now supplies VANCOMYCIN in both saline and dextrose presentations, providing additional therapy options for a critical antibiotic that has appeared periodically on the FDA Drug Shortage list. In addition, Baxter has now submitted to the FDA for review the third of the nine molecules expected to launch over the next several years.
CE marking for the expanded indication of HEMOPATCH in the European Union for tissue sealing and dura replacement in addition to hemostasis. The advanced surgical patch now has one of the broadest indications available for advanced surgical patches in Europe.
Japanese approval for the expanded use of our flowable hemostat FLOSEAL to include endoscopic surgery.
Marketing authorization in United Kingdom and Denmark, the initial of 20 country approvals sought in 2016 for NUMETA G13E, the only triple-chamber, commercially prepared parenteral nutrition system approved to meet the critical needs of vulnerable neonatal patients.
Enrollment of the first patient in the U.S. clinical trial for VIVIA, an investigational home hemodialysis (HD) system. The trial is designed to study more frequent, extended duration nocturnal home HD therapy (High Dose HD).
Retirement of approximately $3.7 billion of gross debt through utilization of a portion of the retained stake in Baxalta Incorporated (Baxalta) through two debt-for-equity exchanges. At the end of the quarter, Baxter held approximately 30.5 million Baxalta shares and currently intends to utilize this remaining equity through a contribution to its U.S. qualified pension plan and an equity-for-equity exchange. While subject to regulatory approval, both of these transactions are currently expected to be completed during the second quarter.
Financial Results

During the quarter, Baxter reported income from continuing operations of $3.4 billion, or $6.13 per diluted share, on a GAAP (Generally Accepted Accounting Principles) basis. These results included an after-tax net gain of approximately $3.3 billion from the disposition of shares the company retained following the spin-off of Baxalta in July 2015. Partially offsetting these results were net after-tax special items totaling $109 million (or $0.20 per diluted share) primarily related to debt extinguishment, intangible asset amortization, Baxalta related spin-off costs and certain business optimization initiatives.

On an adjusted basis, excluding special items, Baxter’s first quarter income from continuing operations totaled $199 million, or $0.36 per diluted share, exceeding the company’s previously-issued guidance of $0.28 to $0.30 per diluted share.

Sales within the United States advanced 5 percent to $992 million, while international sales totaled $1.4 billion, representing a 4 percent increase on a constant currency basis, and a 5 percent decline on a reported basis. There was no impact on Baxter’s total sales growth in the quarter from U.S. cyclophosphamide.

By business, Hospital Products sales of $1.5 billion increased 4 percent on a constant currency basis and declined 1 percent on a reported basis. Hospital Products performance in the quarter benefited from strong sales of Baxter’s next-generation SIGMA SPECTRUM infusion pump and IV solutions in the United States as well as increased demand for the company’s injectable drug compounding services.

Baxter’s Renal Products sales totaled $898 million, representing a 5 percent increase on a constant currency basis, and a 2 percent decline on a reported basis. Increased demand for peritoneal dialysis products and continuous renal replacement therapies contributed to sales growth in the quarter.

Financial Outlook

Based on the company’s strong first quarter performance, Baxter is raising its financial outlook for full-year 2016. Baxter now expects constant currency sales growth for full-year 2016 of approximately 3 percent, or approximately 4 percent after adjusting for increased U.S. competition for cyclophosphamide. On a reported basis, including the impact of foreign exchange, Baxter now expects sales to increase approximately 1 percent as compared to previous guidance of a decline of approximately 1 percent. In addition, the company now expects earnings from continuing operations, before special items, of $1.59 to $1.67 per diluted share for the full year as compared to previous guidance of $1.46 to $1.54 per diluted share.

For the second quarter, the company expects constant currency sales growth of approximately 4 percent, and on a reported basis, sales growth of approximately 2 percent. Baxter expects earnings from continuing operations, before special items, of $0.38 to $0.40 per diluted share for the second quarter of 2016.

The earnings guidance for the second quarter and full-year 2016 excludes approximately $1.94 and $8.01, respectively, per diluted share of realized gains related to the planned use of the Baxalta retained stake; $0.05 and $0.21, respectively, per diluted share of intangible asset amortization expense; an estimated $0.08 to $0.09 and $0.30 to $0.34, respectively, per diluted share related to business optimization and Baxalta separation-related expense activities; and $0.11 per diluted share of debt extinguishment loss and product related reserve adjustments for full-year 2016. These estimates are based on information reasonably available at the time of this release and future events or new information may result in different actual results. Reconciling for the inclusion of these items results in GAAP earnings of $2.18 to $2.21 per share for the second quarter of 2016 and $8.94 to $9.06 per diluted share for full-year 2016.

About Galeterone
Galeterone is an oral small molecule that utilizes the established pathways, including CYP17 enzyme and androgen receptor inhibition, of the current second-generation hormonal therapies abiraterone and enzalutamide. Galeterone also introduces a distinct third mechanism – androgen receptor degradation – that decreases the sensitivity of androgen receptors to androgen activity, thus leading to reductions in tumor growth. Tokai is developing galeterone for the treatment of patients with metastatic castration-resistant prostate cancer (mCRPC). ARMOR3-SV, the company’s pivotal Phase 3 study of galeterone in treatment-naive mCRPC patients whose prostate tumors express the AR-V7 splice variant, is evaluating whether administration of galeterone results in a statistically significant increase in radiographic progression-free survival as compared to enzalutamide. Tokai is also evaluating galeterone in mCRPC patients who have shown resistance following treatment with second-generation hormonal agents. Tokai has worldwide development and commercialization rights to galeterone.
