Panobinostat in combination with
bortezomib and dexamethasone, is
indicated for the treatment of patients
with multiple myeloma who have
received at least 2 prior regimens,
including bortezomib and an
immunomodulatory agent. This
indication is approved under
accelerated approval based on

• Incorporation of new diagnostic criteria for active multiple myeloma-

• Adoption of a new prognostic scoring system for multiple myeloma- R-
ISS
• 4 new FDA approvals for treatment of early relapsed MM (1-3 prior
lines of therapy)- KRD, ERD, IRD, KD56
• 2 new FDA approvals for relapsed and refractory MM- Daratumumab,
and Velcade, Panobinostat, & Dex.
• A glimpse into the next generation of anti-myeloma therapeutics
demonstrates the potential of further targeted therapy and immune
regulation.
Summary of MM 2015 + a little 2016
32. MMWG Moffitt Myeloma Working Group
• There is no easy algorithm for managing relapsed/refractory
myeloma, especially once facing IMID and PI refractory
disease.
• Patient-specific issues and prior therapy should be used to
determine choice of agents.
• In the right patient population(s) effective new targeted
agents will improve patient outcomes.
• New exciting targets and agents are being explored in
numerous phase 1, 2, and 3 clinical trials that will continue to
change the landscape of MM.
Conclusions
33. MM Clinical Trials at Moffitt
• Newly Diagnosed MM
– Phase 2: Carfilzomib/Revlimid/Dex (weekly Carfilzomib at 70mg/m2)- in all comers
