Quality of life in patients with malignant ascites during catumaxomab treatment: Results from the CASIMAS trial.
2012
e13095^ Background: Malignant Ascites (MA) is associated with a poor prognosis and limited palliative treatment options. To demonstrate the value of a new treatment the assessment of quality of life (QoL) is of particular importance. Following the demonstration of catumaxomab’s potential to stabilize QoL and prolong the time to first deterioration of QoL, results from CASIMAS give evidence that the QoL of patients remains unaffected during catumaxomab treatment Methods: In a two-arm, open-label, multicentre phase II/III study 219 patients were randomized to catumaxomab plus premedication of 25 mg prednisolone (111 pts) or to catumaxomab alone (108 pts) QoL was measured using the EQ-5D visu…
Catumaxomab with and without prednisolone in patients with malignant ascites due to epithelial cancer: Results from the phase IIIb CASIMAS study
2012
e13097^ Background: The primary objective of this study was to compare catumaxomab with prednisolone (CP) to catumaxomab without prednisolone (C) as 3-hour intraperitoneal (i.p.) infusion by demonstrating superiority for safety and non-inferiority for efficacy of the CP arm. Methods: 219 patients were randomized to catumaxomab plus premedication of 25 mg prednisolone (111 pts) or to catumaxomab alone (108 pts). The primary endpoint was the composite safety score (CSS) summarizing the worst CTCAE grades for the main TEAEs (pyrexia, nausea, vomiting, and abdominal pain). A potential impact of prednisolone on efficacy was assessed by the co-primary endpoint puncture-free survival (PuFS). Furt…
Catumaxomab: a bispecific trifunctional antibody.
2009
The trifunctional bispecific monoclonal antibody catumaxomab has two binding specificities directed at epithelial cell adhesion molecule (EpCAM) and the T-cell antigen CD3. With its Fc-fragment, catumaxomab additionally binds accessory cells such as dendritic cells, macrophages and natural killer cells. The trifunctional approach thus leads to unrestricted but specific killing of epithelial tumor cells by major histocompatibility complex without the need for preactivation or external costimulation. The tumor-associated antigen EpCAM is strongly expressed in carcinomas of various origins including colon, rectum, ovarian, gastric, esophagus, lung, pancreas, breast and head and neck. Expressio…
Deterioration in quality of life (QOL) in patients with malignant ascites : Results from a phase II/III study comparing paracentesis plus catumaxomab…
2012
Background: Malignant ascites (MA) is associated with poor prognosis and limited palliative therapeutic options. Therefore, quality of life (QoL) assessment is of particular importance to demonstrate new treatment value. Following the demonstration of the superiority of catumaxomab and paracentesis over paracentesis on puncture-free survival, this analysis aimed at comparing deterioration in QoL between both the treatment options. Patients and methods: In a randomised, multicentre, phase II/III study of patients with MA due to epithelial cell adhesion molecule (EpCAM) positive cancer, the QoL was evaluated using the European Organisation for Research and Treatment of Cancer Quality of Life …
Test system for trifunctional antibodies in 3D MCTS culture.
2009
The aim of the present study was to assess the feasibility of a 3D tumor cell culture model, that is, multicellular tumor spheroids (MCTSs) as an adequate model for micrometastases and therefore as a pharmacological model for efficacy testing of trifunctional therapeutic antibodies. Unlike conventional monolayer cultures, spheroids allow researchers to study parameters, such as 3D cell shape, 3D cell arrangement and microenvironment, and penetration efficiency of defense cells that may largely influence the efficacy of antibody treatment in vivo. The authors established a long-term coculture of human MCTSs with peripheral blood mononuclear cells (PBMCs) to test the anticancer effect of the …
Treatment of Malignant Ascites with a Second Cycle of Catumaxomab in Gastric Signet Cell Carcinoma - a Report of 2 Cases
2014
<b><i>Summary</i></b><b><i>Background: </i></b>Malignant ascites is a frequent complication in gastrointestinal malignancy and is unresponsive to systemic therapies. Therapeutic options are limited, and repeated paracentesis is associated with increased loss of fluids and proteins, and impaired quality of life. The bi-specific trifunctional antibody catumaxomab has been approved for the treatment of refractory ascites. It has been proposed that repeated application leads to formation of human anti-mouse antibodies with a decrease in effectiveness and potentially hypersensitivity reactions. <b><i>Case Report: </i></b>Her…
