Patient charactaristics: Efficacy and safety of brentuximab vedotin in combination with bendamustine as 2nd line salvage therapy and potential “bridge” to stem cell transplantation for patients with refractory Hodgkin Lymphoma Eshrak Shaibani, Panayotis Kaloyannidis, Mohammed Ali, Ahmed Al Shaghier, Khalid Al Anezi, Hani Al Hashmi Department of Adult Hematology and Stem cell transplant, King Fahad Specialist Hospital, Dammam, Saudi Arabia Treatment: Route of administration intravenously Hospitalization conditions outpatient basis Administration schedule 3-week cycles. Doses brentuximab 1.8 mg/kg on day1 bendamustine 90 mg/m2 on days 1&2 B& B administered cycles (med) 2 (2-5) Introduction: High dose chemotherapy and autologous stem cell transplantation (autoSCT) represents the most reliable curative approach for patients (pts) with refractory or relapsed Hodgkin’s lymphoma (HL) after induction therapy. Nevertheless, the outcome of pts failed post 1st line salvage therapy is extremely poor and only 15-20% can achieve long term survival. For the majority of these pts the 2nd salvage regimen remains ineffective; therefore there is an unmet need for more effective and less toxic approaches. Brentuximab vedotin and Bendamustine have been tested as single-agents in refractory CD30+ lymphomas, demonstrating significant activity and a favorable safety profile. However, the published data of their combination (B&B) as salvage treatment are to date limited Result: Overall response ( > 80% , PET criteria) 4/6 (67%, all HL pts) Progressed disease 2/6 (33%) Toxicity (WHO≥3) myelotoxicity 0 liver 0 kidney 0 neurological 0 infections 0 Aim: To evaluate the efficacy and safety of Brentuximab vedotin & Bedamustin (B&B) combination.ation in refractory HL Patient charactaristics: Number of patients 6 Age (med) 26 (17-34)ys Diagnosis HL 6 Previous salvage treatment ESHAP x 2 5 auto SCT 1 Stage before B&B-treatment II 2 III 2 IV 2 B-symptoms 2 Effect of BB on moblization: 2/4 responders were mobilized with Cyclophosphamide : 2 gr/m2 GCSF 10 mcg/kg Collected CD34+ cells 4,1 & 7.7 x106/kg Long term outcome: Pt response to B&B Additional treatment status post B&B Time #1 yes auto Alive/dis.free +10 mos #2 yes auto Alive/dis.free +10mos #3 yes auto Alive/dis.free +5mos #4 yes allo Alive/dis.free +8 mos #5 no palliative Alive +11mos #6 no palliative Alive +12 mos CONCLUSION: Retrospective study with small series of patients Seems that the B&B combination treatment is an efficacious and safe approach in patients with refractory HL The B&B combination merits further investigation as salvage treatment Refremsess: Zinzani PL et al.
