The document discusses immunotherapy strategies for multiple myeloma. It summarizes that while current therapies have improved survival, most patients still relapse. It then reviews several immunotherapeutic approaches including allogeneic stem cell transplantation, vaccination strategies targeting antigens like MAGE and idiotype, dendritic cell-based vaccines, and monoclonal antibodies targeting proteins like CS1, CD38, and CD138. Emerging cellular immunotherapies using chimeric antigen receptor (CAR) T cells and natural killer cells targeting myeloma antigens are also discussed. Clinical trials of these approaches demonstrate feasibility and some early signs of efficacy but also highlight ongoing challenges to further improve outcomes.
It is a neoplasm of B-cell lineage; proliferation of the cells forms a monoclonal population of plasma cells and produces a single type of Ig/Ig fragment.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

9. Allogeneic stem cell transplantation:
controversies remain
• Exploit the graft vs myeloma affect
• DLI’s have been used1
• Chronic GVH may predict for long term disease
control2,3 but this data has not been consistent
• Conflicting data in randomized studies comparing
tandem auto SCT vs auto- allo SCT4,5
• But true effect of allo SCT may take longer than 5
years to emerge
• Myeloablative (MA) allo SCT associated with 50%
TRM but some long term survivors (30-40%) 6
• Outcomes may be improved with better modern
supportive care measures 1. Tricot, Blood 1996

6. Barlogie JCO 2006
11. MAGE
• MAGE-C1/CT7 and MAGE-C2/CT10: genes that
appear to be expressed in MM, solitary
plasmacytomas and MGUS1
• Function yet unknown
• MAGEC1/ CT7 gene frequently expressed in
advanced MM and is associated with worse
overall survival (OS) 2
• Resultant protein is immunogenic
• Thus potential cancer/testis antigen (CTA) /target
for immunotherapy
1. De Carvalho, Cancer Immunol Immunother 2013
2. Andrade, Cancer Immun, 2008
12. Clinical trial of MAGE-A3/Poly-ICLC immunizations
Followed by Adoptive Transfer of Vaccine-Primed and
Costimulated Autologous T Cells
• Phase 2 trial, 27 pts undergoing auto SCT for MM
• MAGE-A3 cancer-testis antigen (CTAg) vaccine
• Injected with TLR-3 agonist Poly-ICLC (Hiltonol)
adjuvant GM-CSF to enhance T-cell priming/ boosting
• Co-injection of Prevnar vaccine
• The protein also contains the HIV-1-TAT membrane
translocation sequence to facilitate formation of MHC
class I complexes
• Lenalidomide maintenance was started at day 100
1. Rapoport, Clin Cancer Res 2013
14. Results
• T-cell infusions were well tolerated
• Vaccine injection site reactions occurred in >90 pts
• 2/9 pts developed sterile abscesses
• MAGE-A3–specific CD8 T cells seen in 7 of 8 evaluable
HLA-A2 pts (88%)
• Vaccine-specific cytokine producing T cells generated in
19 of 25 patients (76%)
• Antibody responses developed in 7/9 patients (78%)
who received montanide and only weakly in 2/18
patients (11%) who did not
• 2-year OS was 74% and 2-year EFS was 56%
1. Rapoport, Clin Cancer Res 2013
16. Results
Limitation: MAGE-A3 expression in the myeloma cells was not required for
study entry; thus reducing ability to evaluate vaccine-specific T- and B-cell
responses
Double positive vaccine-directed IFN-gamma responses on CD4 and CD8 T
cells together was possibly associated with better EFS
1. Rapoport, Clin Cancer Res 2013
17. Idiotype Vaccine
• Targets the variable Ig on surface of plasma cell
• Idiotype-specific T cells at a low frequency have been
detected in 90% of patients with MM or MGUS1
• Induction of CTL activity against autologous myeloma
cells also shown after stimulation with idiotype-loaded
DCs
• Hypothesis that idiotype-specific response diminishes
MM progresses
• Thus far clinical trials have shown safety and some T
cell responses but no definitive clinical response.
1. Yi, Blood 1995
18. Dendritic cell-based vaccines
• DC’s from MM pts can present idiotype
determinants to autologous T cells1
• DC-tumor cell fusions
– Protection against MM in murine model2
• Vaccination with DC-fusion induces tumor immunity
and may work best in post-SCT setting when
minimal T regs
• Most efficient strategy may be vaccination with
lenalidomide on board as there may be decrease in
T cell PD-1 expression and inhibition of T regs
• Basis for upcoming BMT CTN 1401 trial

27. SAR 658094 Anti-CD38 MoAb
• SAR decreases MM cell adhesion to BM
accessory cells via blockage of CD31-CD38
interaction (An et al, ASH 2014)
• KIR3DL1, HLA-B Bw4-80Ile genotype predictive
of correlated with increased ORR and PFS

47. Conclusions
• Though the timeline for patients with myeloma
has changed a definitive cure is still needed
• Myeloma is a malignancy of immune
dysregulation and likely immune exhaustion
• Therefore immunotherapies likely have an
important role in the treatment paradigm
• Fine tuning of antibody, cellular and vaccine
therapy will eventually lead us to the ideal
partners for the recently developed novel
therapies
Alimitation of this study was that MAGE-A3 expression in
the myeloma cells was not required for study entry, thus
reducing our ability to evaluate the clinical impact of
vaccine-specific T- and B-cell responses
