4 Age-related Incidence of MDS
(per 100,000) Age in 5-year blocks Williamson PJ, et al. Br J Haematol Aug;87(4):743-5.

5 Talk Outline Therapeutic Options The Scottish Perspective Low Risk MDS
High Risk MDS The Scottish Perspective Scottish Medicine Consortium (SMC) How it works What is good & what is bad!

6 Therapeutic Options Low Risk MDS – Main problem is anaemia
High Risk MDS – Main problem is bone marrow failure & leukaemia

7 Therapeutic Options Low Risk MDS
Supportive care/ blood transfusion /iron Chelation Erythropietic stimulating agent (ESA) Immunosuppression Lenalidomide High Risk MDS Supportive care Azacitidine Chemotherapy Stem cell transplantation

8 Best supportive care Red cell transfusion on demand
Antibiotics for treatment & prevention G-CSF during infection Iron chelation therapy

9 Treatment of Anaemia in MDS
Transfusion Growth Factors Symptomatic anaemia in low risk MDS Immunosuppression with Antithymocyte globulin Lenalidomide in 5q-

12 Iron chelation is beneficial on survival in thalassaemia
Survival by Birth Cohort: University College London Hospitals 100% (n=42) 1.00 (n=39) 0.75 (n=21) 69% Survival probability 0.50 Davis and Porter conducted a study of survival probability in 103 patients with beta-thalassemia who were born between 1955 and ,2 These patients were treated with transfusion plus deferoxamine at University College London Hospital. Survival curves show improvement with advances in care. Patients born between 1955 and 1964 had a 69% survival rate at age 40 years. Patients born between 1965 and 1974 had a 78% survival rate at age 35 years. Patients born after 1974 had a 100% survival rate at the time of analysis. The overall survival rate among all birth cohorts was 78% at age 40 years. These survival curves compare favorably with those from the UK Thalassaemia Register. 0.25 Analysis September 2000 yrs 10 20 30 40 Age (years) Davis and Porter. Adv Exp Med Biol. 2002;509:91.

14 Which patients if any should get iron chelation?
IPSS score low or int-1 Ferritin should be ng/ml or clinical or radiological evidence of iron loading at the start of chelation This would often correlate with units of red cells transfused Candidates for allograft in whom there is a significant delay until the procedure

15 Treatment of Anaemia in MDS
Transfusion Growth Factors Symptomatic anaemia in low risk MDS Immunosuppression with Antithymocyte globulin Lenalidomide in 5q-

16 20 Years experience of erythropoietin +/- G-CSF therapy in MDS
Overall response rate ~20-40% Best response group ~ 60-70% Refractory anaemia Low endogenous EPO level (<500mU/ml) Low transfusion requirement (<2u/month)

17 Prototype model for selecting patients for treatment with EPO + GCSF
Score >+1 Good response 74% RA, RARS, RAEB -1 to +1 Intermediate response 23% < -1 Poor response 7% Serum EPO <100 +2 >500 -3 Unit/mth < 2 +2 = or >2 -2 Hellstrom et al, BJHaem 2003, 120,

18 The ‘nitty-gritty’ of EPO therapy
Is there a quality of life benefit for EPO responders? Is EPO therapy cost-effective? Is there a survival advantage for EPO responders?

19 Your doctors have still not answered two major questions in low risk MDS!
Is erythropoietin therapy more beneficial than transfusion? Is iron chelation therapy beneficial?:

20 Our drug companies are trying to answer these questions!
Johnson & Johnson – EPOANE3021 Erythropoietin versus Placebo Novartis – TELESTO Iron chelation (Exjade) versus Placebo

31 Management Jehovah’s Witness!

32 Case 1 Question 2 What would you recommend?
Tell him not to be so daft and have a blood transfusion? Tell his wife and daughter (not JWs) to persuade him to have a blood transfusion? Treat him with a trial of erythropoietic stimulants (EPO, Darbopoietin)? Try something else?

33 Case 1 Answer 2 What would you recommend?
Tell him not to be so daft and have a blood transfusion? Tell his wife and daughter (not JWs) to persuade him to have a blood transfusion? Treat him with a trial of erythropoietic stimulants (EPO, Darbopoietin)? (high predicted response) Try something else?

38 Exceptional Circumstances Group
Approved trial of lenalidomide based on fulfilling local criteria for exceptionality: ‘Because of his religious beliefs he is unable to receive the standard therapy-blood transfusion’

39 22/04/09 started first cycle lenalidomide
Case 1 continued 22/04/09 started first cycle lenalidomide 10mg od for 21 days out of 28 days 12/05/09 GP phoned: Bedridden, home oxygen, not coming to hospital again, no further treatment Most recent Hb 4.3g/dl

41 Case 1 What should you display in your MDS clinic?

42 Therapeutic Options High Risk MDS – Main problems are bone marrow failure & leukaemia Supportive care Azacitidine Chemotherapy Stem cell transplantation

43 Azacitidine It has been suggested that azacitidine may switch on important anti-cancer genes

44 AZA 001: Study design schematic
Azacitidine 75 mg/m2 daily for 7 days, every 28 days Investigator selection of conventional care regimen Randomisation Conventional care regimen Best supportive care only Low-dose ARA-C (20 mg/m2 daily for 14 days every days) Standard chemotherapy (7 + 3)

45 AZA-001: Vidaza is the only licensed drug that has demonstrated a survival advantage in Int-2 and High-risk MDS Vidaza – increases the median survival to 24.5 months (compared to 15 months with CCR) providing a 9.4 month benefit In a post hoc analysis Vidaza doubled 2-year survival rate compared with CCR (p<0.001) Fenaux P, et al. The Lancet Oncology 2009; 10:

46 AZA-001: Setting a new standard in transfusion independence
100 80 60 40 20 % of transfusion Independent patients 90 70 50 30 10 45.0 11.4 33.6% difference p<0.0001 Vidaza CCR Santini V. J Clin Oncol 2008 Fenaux P, et al. The Lancet Oncology 2009; 10: Vidaza SmPC December 2008.

47 Azacitidine (Vidaza) Standard of care for high risk MDS patients who are not candidates for transplantation Approved by NICE ( great help of UKMDS Patient Forum) Not approved by SMC

48 The Scottish Perspective
The Scottish Medicines Consortium Statutory body which is part of: Quality Improvement Scotland (QIS) To advice the NHS in Scotland as to the cost effectiveness of new treatments

49 SMC vs. NICE SMC decisions only apply in Scotland
NICE single drug decisions only apply in England, Wales and Northern Ireland NICE multiple treatment assessments apply in Scotland and replace any existing SMC guidance

50 The workings of the SMC New Drug Committee Patient Access Scheme
Assessment Group (PASAG) Drug Company Main SMC Committee Final Advice Document Exjade Azacitidine

51 What about stem cell transplantation?

52 Current transplant activity in MDS
EBMT 2008: 1147 allografts for MDS ~ 10% of total 1333 MDS patients > 50yrs allografted

53 Considerations for all potential transplant candidates
Disease characteristics Patient characteristics Age Co morbidities (other diseases or disabilities) Iron status at transplant

54 40 yr old female works in our medical illustration department
First time blood donor Failed the screening test Subsequent FBC Hb 12.1 g/dl MCV 103 fl WCC 1.9 X 109/l Neut 1.2 x 109/l Plat 258 x 109/l Blood film: Significant dysplasia

55 Bone Marrow Hypercellular-confirmed on trephine Trilineage dysplasia Blasts 1% Karyotype: 46, XX, der(21)t(1;21)(q11;p11)[6] 46,XX[4]

56 Diagnosis: MDS Refractory cytopenia with multilineage dysplasia
Cytogenetic risk group- Standard ?? IPSS score 0.5 Intermediate 1

57 What is your plan? Watch and wait-no plan to transplant
Proceed to transplant now? Watch and wait-plan to transplant at progression? Something else?

58 Answer 1 What is your plan?
Watch and wait-no plan to transplant Proceed to transplant now? Watch and wait-plan to transplant at progression? Something else?

59 Question 2 Would you… Proceed to transplant as first line therapy?
Give one or two cycles of chemotherapy first?

60 Answer 2 Would you… Proceed to transplant as first line therapy?
Give one or two cycles of remission induction therapy prior to transplant?

61 Question 3 She is exactly 40 yrs old Would you…
Perform a traditional myeloablative conditioned transplant? Perform a Reduced Intensity conditioned transplant (RIC)?

62 Answer 3 She is exactly 40 yrs old Would you…
Perform a traditional myeloablative conditioned transplant? Perform a reduced intensity conditioned transplant (RIC)?

63 Outcome?! RIC allograft 11/05/07 Alive and well
Ongoing morphologic and cytogenetic remission No GVHD and back at work full time Would it be otherwise given I present it to you!

64 Thank you for listening!
