Multikinase inhibitors sorafenib and sunitinib as radiosensitizers in head and neck cancer cell lines

2017

Background Radioresistance is a common feature of head and neck squamous cell carcinoma (HNSCC). We previously showed that the irradiation- activated vascular endothelial growth factor (VEGF)-extracellular signal-regulated kinase (ERK)-axis is fundamental for the survival of resistant tumors. In this study, we examined if treatment with potent multikinase (MK) inhibitors, sorafenib and sunitinib, could radiosensitize tumor cells. Methods Cultured HNSCC cell lines were treated with inhibitors and subsequently irradiated. Radiosensitizing effects were functionally assessed by annexin-V apoptosis and clonogenic assays and confirmed by Western blot. Additionally, we surveyed human HNSCC tissue …

Real-world data confirm the effectiveness of caplacizumab in acquired thrombotic thrombocytopenic purpura

2020

Abstract Acquired thrombotic thrombocytopenic purpura (aTTP) is a rare but life-threatening condition. In 2018, the nanobody caplacizumab was approved for the treatment of adults experiencing an acute episode of aTTP, in conjunction with plasma exchange (PEX) and immunosuppression for a minimum of 30 days after stopping daily PEX. We performed a retrospective, observational analysis on the use of caplacizumab in 60 patients from 29 medical centers in Germany during acute disease management. Caplacizumab led to a rapid normalization of the platelet count (median, 3 days; mean 3.78 days). One patient died after late treatment initiation due to aTTP-associated complications. In 2 patients with…

ADAMTS13 and VWF activities guide individualized caplacizumab treatment in patients with aTTP

2020

Abstract Introduction of the nanobody caplacizumab was shown to be effective in the treatment of acquired thrombotic thrombocytopenic purpura (aTTP) in the acute setting. The official recommendations include plasma exchange (PEX), immunosuppression, and the use of caplacizumab for a minimum of 30 days after stopping daily PEX. This study was a retrospective, observational analysis of the use of caplacizumab in 60 patients from 29 medical centers in Germany. Immunosuppressive treatment led to a rapid normalization of ADAMTS13 activities (calculated median, 21 days). In 35 of 60 patients, ADAMTS13 activities started to normalize before day 30 after PEX; in 11 of 60 patients, the treatment was…
