  1. Esperienza clinica con le antracicline liposomiali nel MM Massimo Offidani Clinica di Ematologia Azienda Ospedaliero-Universitaria Ospedali Riuniti di Ancona

  2. Effect of single drug doxorubicin in MM 9 rel/ref MM pts: 1 PR and 1 MR (Alberts DS et al: Cancer Chem Rep, 1975) Review of literature rel/ref MM: 5% PR (Rodjer S et al: Haemat J, 2000) Effect of doxorubicin combinations in MM VAD: PR=50-65%, VGPR=15%, CR/nCR=4-8%

  3. Anthracyclines in Multiple Myeloma • Doxorubicin is one of the most potent antibiotics used in tumor chemotherapy • Longer exposure to higher concentrations results in higher plasma cell kill • Short half life have negative impact on the administration modality • Total cumulative effect limits its use in chronic disease processes

  4. Rationale for Pegylated Liposomal Doxorubicin in MM • Increased angiogenesis in BM of MM patients • Longer plasma half life • Possible more effective against MDR positive cells • Improved safety profile compared to free doxorubicin • Outpatient regimen

  5. Why CAELYX in Multiple Myeloma? • CAELYX has a favorable safety profile • Phase III DVd vs VAd • RR, PFS, OS similar • Significantly less neutropenia (10 vs 24%) • Alopecia (20 vs 44%) • Less supportive care (CVA, GFs) • DVd regimen decreased angiogenic activity in BM • Need for modifying anthracycline-based regimens with the addition of new-drugs • Thalidomide, Lenalidomide • Bortezomib Rifkin et al. Cancer. 2006;106:848-858 Hussein et al. Clin Lymphoma Myeloma. 2007;7(suppl 4):S145-S149

  6. Preclinical rationale for Pegylated Liposomal Doxorubicin + IMiDs in MM Different but complementary mechanism of action • Both antiangiogenic • Both cytotoxic effect with different mechanism • IMiDs target microenvironment • IMiDs exert immune activation effect • Nonoverlapping toxicities

  7. Preclinical Rationale for Combining CAELYX + Bortezomib • Additive or synergistic effects are seen in both in vitro1,2,3 and in vivo4 model systems • Interactions occur through multiple pathways to enhance anti-tumor efficacy • Bortezomib abrogates anthracycline resistance • NF-kB1,2, Bcl-2, P-glycoprotein, DNA damage repair3 • Anthracyclines abrogate bortezomib resistance • Suppression of stress response protein MKP-14 1Mark et al.
