More Optimal Donors Needed Continuing with routine recruitment efforts will not fully support patient needs OneMatch, along with its internal and external partners, must focus on recruiting optimal donors for our Transplant Centres and our patients in need
Why are young males, 17-35 considered optimal donors? More likely to be selected because of their size Increased potential for better post-transplant outcome (less graft vs. host disease, better chance of engraftment) CMV negative donors more likely to be young
Why are young males, 17-35 considered optimal donors? Survival rate statistically significant at one year when product from younger donor (NMDP study) The greatest gap in finding matches is with ethnically diverse patients The largest registries in the world have significantly more young males and therefore OneMatch is often not the registry of choice we need to change this 18
Why are young males, 17-35 considered optimal donors? Better investment at registration if donors are on the Network for longer OneMatch has a preset funding envelope - focusing on ethnically diverse males 17-35 brings best value for health care funding provided 19

Need for Additional Stem Cells OneMatch is an active member of the International Network of stem cell registries and on behalf of all Canadian patients needing a stem cell match, we search and have access to: 19.8M potential adult donors from 66 registries in 48 countries; and, 543K public CBUs from 46 cord blood banks in 30 countries. source: BMDW, September 7, 2012 However, even with this access, we are still only able to find matches for about 50% of patients AND it is harder to find matches in many ethnic groups due to under-representation on registries worldwide. With the continued significant increase in demand and Canada s unique and large ethnic diversity, there is significant need for a national, public cord blood bank. 23
Canadian Aboriginal Recipients Registry data (2005-2011): 102 recipients identified as aboriginal 40 transplanted (39%) 2 full HLA match, rest various degrees of mismatch 7 from Canadian donors Median time to transplant 8.2 months Vs. 5.8 months for non-aboriginal recipients Note 10 searches still active as of Dec 2011 and 1 in work up 50 searches cancelled 24
Need for Additional Stem Cells US National Marrow Donor Program: AABB 2011 9 million donors on registry Adds 1 million per year to registry Rate of 8/8 match (HLA A B C DRB1) Caucasian 80% Asian 30 40% South Central American Black 15% Due to under representation in donor pool AND increased diversity in the minority groups 25
Need for Increased HLA Diversity Increasing donor number has less impact vs pre 2004 Duplication of common haplotypes Need to increase less common haplotypes even more so than common ones Eg assume equal registry size probability of match if African ancestry = 30% vs 60% in non Africans Due to HLA diversity WITHIN the population NMDP 2011 26
Cords and Ethnic Diversity Higher likelihood of match as only 6/6 required HLA A B DR US NMDP data 150,000 CBU and add 25,000 per year Likelihood of 6/6 match European descent: 15% adult recipient, 35% child Likelihood of 4/6 match 75% in ALL adult populations Virtually all children in all ethnic groups 27
Need for a National Public Cord Blood Bank An increasing majority of all unrelated paediatric stem cell transplants in Canada are performed using cord blood and there has been and increase in the adoption of cord blood for adults (two cords used). Cord blood has distinct advantages over bone marrow or PBSCs: More lenient HLA matching requirements With current inventories 95% of children will have at least a 4/6 HLA antigen matched unit With adequate cell dose outcomes similar for 4/6 vs 6/6 HLA matches Banks can be adjusted to increased ethnic (HLA) diversity Units are available immediately (1 day 2wks vs 3 10 mos for adult stem cells) Lower risk of graft-vs.-host disease (GvHD) Minimal risk to donor (mother and baby) All cord blood units supplied by Canadian Blood Services for unrelated transplant are imported from international sources. The cost of importing cord blood units continues to increase $42,000 ea. Uncoordinated, multiple banks cannot meet the need for a HLA diverse inventory that is required for Canadian patients. 28
Official Announcement March 14, 2011 Ministers of Health announce Canada's first national, publicly-funded umbilical cord blood bank $48 million investment over eight years. Please note: $12.5M of the $48M will be raised over three years by Canadian Blood Services fundraising campaign. April 1, 2011 OneMatch Public Cord Blood Bank project began in Ottawa, as per approved model by the Ministers of Health April 2, 2013 Go-live in Ottawa Spring 2014 Go-live in Edmonton, Vancouver and Toronto 29
OneMatch Public Cord Blood Bank Model Includes at least four collection cities and two manufacturing facilities for processing, storage and distribution. Please note: We will also be working on cord blood collection kits that can be sent to targeted areas outside of cities listed below to reach Aboriginal communities, for e.g. Canadian Blood Services OneMatch National Public Cord Blood Bank (inventory of 20,000 units within 8 years*) Medical and Scientific Advisory Committee Searching, Matching OTTAWA Manufacturing Facility (April 2, 2013) EDMONTON Manufacturing Facility (2014) CBS Support HLA Testing Transmissible Disease Testing CBS Research Ethics Committee (units unsuitable for transfusion) Marketing & Recruitment *Optimal size of a national cord blood inventory is currently estimated to be approximately 20,000 units, which can be achieved within eight years using this Model.

Cord Blood and Research Approximately 20% to 40% of the cord blood units collected are of sufficient volume and/or cell count to be used for transplantation. Donors will have the option to designate their cord for research in Canada if it cannot be used for transplantation. Working with stakeholders to ensure a comprehensive system is in place for Canadian researchers to access cord units in a rational, fair and transparent manner CBS Research Ethics Board Canadian Stem Cell Network Canadian Blood and Marrow Transplant Group 31
Informed Consent Established a collaboration with Dr. Bartha Knoppers (McGill University) to: Develop an informed consent protocol for cord blood donation for research for the OMPCBB Develop content for an information pamphlet for potential UCB donors for research. June 2012 Stakeholders Workshop Gain an understanding of stakeholders perspectives around donor consent of UCB for research Inform stakeholders about the OMPCBB Establish relationships between stakeholders across Canada to build long-term trust and to strengthen the community of experts 32
Workshop In partnership with 20 experts including researchers and clinicians from across Canada and
Scope and Timelines The Canadian Blood Services OneMatch Public Cord Blood Bank will consist of collection sites (hospitals) in Ottawa, Toronto, Edmonton and Vancouver, with processing and storage sites at our two existing stem cell manufacturing facilities in Ottawa and Edmonton. The goal is to reach a minimum of 20,000 cord blood units in storage for transplantation by March 31, 2019 eight year period beginning April 1, 2011. Phase I of the cord blood bank will be operational in Ottawa in April 2, 2013, and in the remaining sites, Phase II, in 2014. FY 2011/12 FY 2012/13 FY 2013/14 FY 2014/15 Ottawa Collection & Manufacturing Edmonton Collection & Manufacturing Vancouver Collection Toronto Collection PHASE I PHASE II PHASE II PHASE II 34
Cord Blood Banking Process Seven key processes for cord blood will include capturing and centralizing data on a per unit basis for traceability, searching and matching, information management, ad-hoc queries, reporting, data export and modeling for optimization.

The Selection and Acquisition of Unrelated Cord Blood Grafts Dr. Juliet Barker et al, Blood 2011; 117:2332-9. Transplant centres want to know about factors that influence the graft potency (i.e. volume, TNC, CD 34 + ) They want to know IDM are negative They want to be ensure the unit is matched They want to know the unit comes from an accredited bank They want to know their patient will not acquire a genetic or serious disease 48
