• The CHAMPION-1 study is the first clinical trial to investigate carfilzomib on a once-weekly dosing schedule with dexamethasone.• Once-weekly carfilzomib (30-minute infusion; 20 and 70 mg/m 2 ) with dexamethasone is feasible and effective in relapsed/refractory MM. , the most common grade ‡3 adverse events were fatigue (11%) and hypertension (7%). Overall response rate at 70 mg/m 2 was 77%. Median progression-free survival was 12.6 months. These findings merit additional evaluation of the once-weekly dosing regimen. This trial was registered at www.clinicaltrials. gov as #NCT01677858. (Blood. 2016;127(26):3360-3368)

Hepatocellular carcinoma (HCC) is one of the most malignant cancers with poor clinical outcome. The protein kinase human monopolar spindle 1 (hMps1/TTK) gene expression is significantly increased in HCCs. However, its contributions to hepatocarcinogenesis remain unclear. In this study, we found that TTK was overexpressed in 77.63% (118/152) HCC specimens. Elevated TTK expression positively correlated with large tumor size and presence of the portal vein tumor thrombus (PVTT). Demethylation in its promoter increased TTK expression in HCC. In vitro assays revealed that TTK not only promoted cell proliferation and anchorage-independent growth, but also cell migration. Subsequent investigations revealed that TTK activated Akt/mTOR pathway in a p53 dependent manner. We also found that TTK specific kinase inhibitor AZ3146 could decrease HCC cell growth. In conclusion, TTK contributes to HCC tumorigenesis via promoting cell proliferation and migration. It may serve as a novel biomarker and a potential target in HCC cancer therapy.

PAmAb is safe, well tolerated, and bioavailable after a single intramuscular or intravenous dose, which supports further clinical development of PAmAb as a novel therapeutic agent for inhalational anthrax.
