Bendamustine First synthesized in the 1960 s in Jena, in the former East Germany. Limited data published during the initial period of investigation Used in the treatment of NHL,CLL, Multiple Myeloma, Hodgkin s disease and solid tumors, i.e. Breast cancer and small cell lung cancer Effective in cell lines that are refractory to alkylating agents Only partial cross-resistance with melphalan and cyclophosphamide as a rational for using bendamustine in previously treated patients with low-grade lymphoma
Bendamustine Extensive DNA-damage Like other alkylating agents, it causes intra-stand and inter stand cross-links between DNA bases Tageja N, et al. Cancer Chemother Pharmacol (2010) 66:413-423 More durable and more extensive DNA-damage than other alkylating agents. It is also associated with a relatively slower repair of DNA damage than other alkylating agents.
Bendamustine Apoptosis via a TP53-dependent mechanism; Inhibition of mitotic checkpointsregulating genes, such as CCNB1, As a result of this distinctive activity AURKA profile, and Bendamustine PLK1, this drugs also show limited cross-resitance with agents triggers usually a complex employed phenomenon, for upfront and salvage treatments of HD known including as mitotic anthracyclines, catastrophe, that dacarbazina, cyclophosphamide, ifosfamide, activated non melphalan apoptotic cell and death carmustine. pathway in tumor cells Activates an exonuclease-1 (EXO1) Dna repair Leoni L.M. et al, Clin Canc Res 2008; 14 (1) January 1, 2008

Bendamustine in Hodgkin Lymphoma: Phase II studies & real life retrospective studies Significant response rate Favorable toxicity profile: - manageable/expected hematologic toxicity (thrombocytopenia, infection) -mild non-hematologic toxicity Adequate response duration Response independent from prior: - chemosensitivity status, - ASCT, allo-sct - Bendamustine ADI Short time to best response (2-4 cycles) Early CRs mantained Early PRs do not usually upgrade
Bendamustine in Hodgkin Lymphoma Does it work? Yes, it does! How it works? May be differently than in B-NHL (???) Can we combine it with other agents in rr-hl? Yes, we can! How? Why? 1.To cytoreduce preallosct 2. To palliate 3. As a platform for combination with target-based agents Image: L. Leoni. Clinical Advances in Hematology & Oncology 2011,9 (S 19),
