Prognostic factors for remission of and survival in acquired hemophilia A (AHA): results from the GTH-AH 01/2010 study
Acquired hemophilia A (AHA) is caused by autoantibodies against factor VIII (FVIII). Immunosuppressive treatment (IST) results in remission of disease in 60% to 80% of patients over a period of days to months. IST is associated with frequent adverse events, including infections as a leading cause of death. Predictors of time to remission could help guide IST intensity but have not been established. We analyzed prognostic factors in 102 prospectively enrolled patients treated with a uniform IST protocol. Partial remission (PR; defined as no active bleeding, FVIII restored >50 IU/dL, hemostatic treatment stopped >24 hours) was achieved by 83% of patients after a median of 31 days (range 7-362…
Polatuzumab vedotin as a salvage and bridging treatment in relapsed or refractory large B-cell lymphomas
The antibody-drug conjugate polatuzumab vedotin (pola) has recently been approved in combination with bendamustine and rituximab (pola-BR) for patients with refractory or relapsed (r/r) large B-cell lymphoma (LBCL). To investigate the efficacy of pola-BR in a real-world setting, we retrospectively analyzed 105 patients with LBCL who were treated in 26 German centers under the national compassionate use program. Fifty-four patients received pola as a salvage treatment and 51 patients were treated with pola with the intention to bridge to chimeric antigen receptor (CAR) T-cell therapy (n = 41) or allogeneic hematopoietic cell transplantation (n = 10). Notably, patients in the salvage and brid…
Prognostic Parameters For Remission Of and Survival In Acquired Hemophilia A: Results Of The GTH-AH 01/2010 Multicenter Study
Abstract Acquired hemophilia A (AHA) is a rare autoimmune disorder caused by neutralizing autoantibodies against coagulation factor VIII (FVIII:C). Immunosuppressive treatment may result in remission of disease over a period of days to months. Until remission, patients are at high risk of bleeding and complications from immunosuppression. Prognostic parameters to predict remission and the time needed to achieve remission could be helpful to guide treatment intensity, but have not been established so far. GTH-AH01/2010 was a prospective multicenter cohort study using a standardized immunosuppressive treatment protocol. The primary study endpoint was time to achieve partial remission (PR, def…
Polatuzumab Vedotin in Relapsed and Refractory (r/r) Large B-Cell Lymphoma (LBCL): Real-World Data of the German National Compassionate Use Program (CUP)
Introduction The antibody-drug conjugate polatuzumab vedotin (Pola) has recently been approved in combination with bendamustine and rituximab (Pola-BR) for patients with r/r diffuse LBCL (DLBCL). Methods To characterize the efficacy of Pola-BR in a real-world setting, we retrospectively analyzed data from 97 patients with r/r LBCL who were treated with Pola in 24 German centers within the national CUP. Clinical baseline and follow-up (FU) data were collected by chart review and summarized descriptively. Progression-free survival (PFS) and overall survival (OS) were analyzed using Kaplan-Meier and Cox regression methods. Fisher's exact test was used to compare categorical factors between gro…
