1 Paris Seminar for Patients & Caregivers: BSRI 2017 On the Path to a Cure Brian GM Durie Saturday, June 10,

2 Black Swan: on the way to a cure Sustained low level disease Favorable immune signature Early Treatment Early detection Decide to seek a cure! 4 5 Sensitive, reliable, widely available MRD testing 2

3 Black Swan Key Concepts Cumulative Driving Mutations MGUS SMM MM Prevention Strategies Early intervention with curative intent New therapies for MRD positive 3

4 istopmm: Iceland Project i S T O P MM Iceland Screens Treats Or Prevents Multiple Myeloma Partners Sigurdur Kristinsson & team, University of Iceland Binding Site CURE Trial 140,000 adults > Age 40 Screen HR SMM Prevent Multiple Myeloma Monitor CURE! What causes myeloma? Establish criteria for classification/progression 4

5 istopmm: Iceland Project istopmm Iceland Screens, Treats or Prevents Multiple Myeloma All 35 laboratories in Iceland participate 5

6 Importance of decode Project decode s whole-genome sequencing project 2,600 Icelanders sequenced DNA samples from 120,000 Icelanders all chip typed 6

8 Understanding Cure Backwards Forward s 2037 Baseline samples MRD Assessment Precise F/U Rx Full Clinical & MRD Testing 8

9 CESAR Trial C urative E strategy S moldering A lto R isk HR SMM KRd x 6 cycles ~50 patients accrued ASCT KRd x 2 cycles Rd x 2 years Primary Endpoints MRD Negative at 1 year 3 years 5 years 9

10 ASCENT Trial Aggressive Smoldering Cure Evaluating Novel Rx Transplant HR SMM 1 st Quarter 2017 set to begin KRd + DARA x 4 cycles ASCT KRd + DARA x 4 cycles KRd + DARA x 4 cycles K DARA x 2 years Primary Endpoints MRD Negative at 1 year 3 years 5 years 10

11 Launch of the NGF Method October 10 th & 11 th,

12 NEXT GENERATION FLOW (NGF): IMF-EuroFlow NGF-MRD Approach Optimal antibody panel * Bulk lyse sample processing Standardized sample processing systematic acquisition of 10 7 Novel data analysis strategies Infinicyt software PCA, file merge, automated gating * CD38 multi-epitope OK with dara Flores-Montero, submitted

13 NEXT GENERATION FLOW Comparison with NGS NGF Applicability 31/31 (100%) Positive 19/27 (70%) NGS 27/31 (87%) 13/27 (48%) Less applicable P < P < 0.05 more sensitive 13

14 Progression-free survival (%) NEXT GENERATION FLOW Excellent Outcome for MRD Negative Patients Patients with adequate marrow sample NGF negative at 3 10 level NGF positive 20 0 P= Time from MRD assessment (months) 14

15 How About a Blood Test? Liquid biopsy NGF detects circulating myeloma cells in SMM and MM: molecular analyses are feasible Blood DNA also shows exact mutations and can guide treatment 15

Leukemia (in press)

18 Additional Piece of the Puzzle Make sensitive, standardized MRD testing available globally 23

19 Achieving a Global Standard for MRD Testing Over 50 researchers in 22 countries! 19

20 Current Opportunities NGF in Blood New Trial Options MM MGUS SMM 1 Low MRD Status 2 MRD NEG MGUS Signature 3 CURE Trials Resistant MRD 20

21 Forward Expectations and Plans Now Documenting functional cure Validation of clinical correlates Expanding cure fraction Expanding achievement of MRD-negative Studying MRD-positive; introducing Rx to eradicate Introduce new MRD blood test Understanding 1/3/5 years Coordinate MRD testing for CURE trials Cross correlate NGS, NGF and imaging Standardized NGF test for bone marrow 21
