Presentation Summary

Cure is Close, but not there yet!…Until then relapse is common (and drug resistance) 

What Is the Future for Relapsed Multiple Myeloma? 

  • Overview: ~ 20 new therapeutics 
    • Small Molecules: Iberdomide, Venetoclax, Selinexor, Melfulfen 
    • Antibodies: Daratumumab, Isatuximab 
    • Antibody Drug conjugates: Belantamab 
    • BITES/Bi-specifics: AMG701, Teclistamab, CC93269, REGN4548,Talquetamab, Cevostamab… and many more 
    • CAR-T: Ide-cel, Ovra-cel, Cilta-cel, LCARB38… many more 
Defining & Treating High-Risk Multiple Myeloma

Dr. Saad Usmani, Levine Cancer Institute

Presentation Summary

  • Recognize MM is not one disease. There is a need for small enrichment design clinical trials for high-risk disease. 
  • Achieving and sustaining MRD negativity matters for HRMM>SDMM 
  • PI/IMiD based induction/maintenance as options  
  • Potential strategies to eradicate MRD in TE/TI HRMM: 
    • CAR-T cell strategies (BCMA, GPRC5D, SLAMF7, FCRH5, etc.) 
    • Bispecific antibody strategies (BCMA, GPRC5D, FCRH5, etc.) 
    • Antibody-Drug Conjugates (BCMA, SLAMF7, etc.) 
  • For Transplant Ineligible elderly MM, use of immune modulation to re-establish immune surveillance and equilibrium. 
    • Role for immune profiling signatures 
  • For pPCL: Strategies incorporating BCL2 inhibition being explored 
    • CelMods, PROTACs, etc. 
Cellular Therapy in Multiple Myeloma

Dr. Noopur Raje, Massachusetts General Hospital

Presentation Summary

Standard Practice in 2021 

  • Triplets in newly-diagnosed patients: RVD/KRD/VCD  
  • Daratumumab now  approved in first line with VMP Dara-Rd with Rd (MAIA) 
  • Quadruplets under investigation
  • Transplant and maintenance SOC 
  • Continuous therapy is the accepted treatment paradigm for myeloma 

Targeting BCMA as a new standard  

  • Effective options:  
    • Antibody drug conjugates  – Belantamab mafodotin (August 2020) 
    • Bispecific T-cell engagers – Several in phase II  
    • Cellular products – Ide-cel (March 2021) 
  • Future will be to define how to combine/sequence these 
  • Next generation approaches will focus on improving efficacy and DOR 

What’s next? 

  • Mechanisms of resistance to anti-BCMA CAR T cell therapy 
  • Strategies to overcome – dual targeting strategies  
    • Other MM target antigen candidates for CAR T 
    • Opportunities for combination treatment 

Hodgkins Lymphoma

Older Patients with Classical Hodgkin Lymphoma 

Dr. John Kuruvilla, Princess Margaret Cancer Centre 

Access Slides & More

Presentation Summary

  • Outcomes are inferior in older patients 
    • Age 60 may not be a relevant cutoff in clinical practice, 70 appears more relevant 
    • Cause of death is not driven by lymphoma deaths, but disease control is also a problem 
    • Patients are under-represented in clinical trials 
  • Second-line outcomes are also inferior 
    • Biology not clearly understood, biomarkers absent
  • Outcomes with novel agents are also suboptimal
  • But goal in this population is to improve disease control and to improve acute and late toxicity 
  • Optimal Approaches for Primary Therapy of elderly cHL
  • Optimal Approaches for RR-cHL in elderly
  • No clear Standard of Care in RR-cHL patients ineligible for ASCT 
  • Salvage therapy Outcomes in the Elderly  
Integrating Novel therapy in Second-Line Hodgkin Lymphoma

Dr. Alison Moskowitz, Memorial Sloan Kettering Cancer Center

Access Slides & More

Presentation Summary

Best second-line therapy? 

  • Chosen according to baseline risk factors 
    • Prior therapy 
    • Baseline metabolic tumor volume (MTV) 
  • Geared toward markers of treatment sensitivity 
    • 9p24.1 amplification 
  • Modified according to early markers 
    • Interim PET 
    • Reduction in MTV or ctDNA 
Early Stage classical Hodgkin Lymphoma

Dr. Graham Collins, Oxford Cancer and Haematology Centre 

Access Slides & More

Presentation Summary

  • Overview of the prior standard based on GHSG trials
  • Overview of response adaptation trial data:
    • UK RAPID study 
    • EORTC H10 study
  • New kid on the block: HD17
  • Individualizing the radiotherapy late effects risks
  • Future directions
Radiation Therapy in the Upfront Management of Hodgkin Lymphoma 

Dr. David Hodgson, Princess Margaret Cancer Centre

Access Slides & More

Presentation Summary

  • There is no “one size fits all”. 
    • ABVD x 6 for everyone or CMT in every early-stage case not best practice.  
    • Getting to the right decision requires multi-disciplinary input and is often a value judgement and therefore requires patient input and physician patience. 
  • Aim to keep breast mean dose <4Gy and cardiac mean dose <10Gy and limit doxorubicin exposure.

  • Brentuximab, Nivolumab in upfront management to replace doxorubicin & RT for selected patients.
  • Better risk stratification – [as available] use quantitative PET metrics, biomarkers.
