Global Perspective on Donor andRecipient Safety: Biovigilance inHematopoietic Cell TransplantationJohn P. Miller, MDPhDVice President and Senior Medical DirectorNational Marrow Donor Program / Be The MatchPublic Forum of the Quebec Biovigilance CommitteeNovember 16, 2016Learning Objectives Understand the nature and goals of the NMDP biovigilance systemfor donors and recipients of hematopoietic progenitor cells (HPC)– Global trends in transplantation– How are HPC donors different from blood, organ and other tissue donors? Describe the NMDP operational processes that support biovigilance– Reporting requirements for donor centers and transplant centers– NMDP reporting requirements domestically and internationally Share incidence data on NMDP biovigilance for donors– Common adverse events– Serious adverse events– Marrow compared to PBSC donors Share best practices moving forward: Emerging cellular therapies2

Key Elements in Donor AE Biovigilance Reported via FormsNet Form 701Medical Quality Assurance Nurses are notified–––– Investigation ensues if appropriateDonor cared for by DC/AC/CC and NMDPNMDP RN staff (TMS/DMS) follow donor to AE resolutionDonor advocacy RN involved if prolonged AEReporting for serious and unexpected AEs plus serious andexpected events of interest as determined by medicaldirector review– vast majority of events reported are non-serious9Key Elements in Recipient AE Biovigilance AE Reporting– TC education regarding what to report, timelines AE training associated with protocols (e.g. 10-CBA) National mtgs (Tandem, NMDP Council, CB Symp) Web resources at Event Processing– Reporting via FormsNet2 (phone or email permitted)– Events investigated (NMDP or other stakeholder)– Confirmed events entered into IMS Tracking and Trending– MasterControl tools, reports; staff review10

Recipient Serious Adverse Event (SAE)Reporting for the NMDP Network SAEs associated with PBSC, marrow and cord blood must bereported promptly to NMDP– Report using FormsNet Form 3001 Rationale for seriousness (death, life-threatening,hospitalization, birth defect, permanent impairment ordisability) Event type / severity using CTCAE Terms and Grading AttributionSome events are not NMDP regulatory responsibility and infowill be passed to the appropriate IND holderAll Recipient AE and Product Complaint Reporting viaFormsNetTM2 Effective 4/15/12Cord BloodNMDP INDOther IND, LicensedMononuclearCellsNMDP FacilitatedFormsNet212MarrowPBSCNMDP FacilitatedNMDP Facilitated

Benefits of Recipient AE Reporting System Single source of event entry in a system (FormsNet 2) with whichthe Network is familiar Once event is entered, the NMDP provides event notification to thestakeholders (CBBs, IND holders, etc)– Enhances ability to comply with all reporting obligations– Single source of event submission allows tracking & trending of eventsproducing more timely– Network notification– Root cause investigation and remedial / corrective interventions13What Happens to AE Reports? Investigation by Medical Services RNs and MDsDissemination of Information: Regulatory reporting by NMDP– DPSM (the NMDP’s DSMB) and IRB– FDA when NMDP is the IND holder Otherwise, NMDP passes through the report to the IND holder– HRSA and other US government stakeholders– Other stakeholders: Network announcements and PI letters– Pharma as applicable (e.g. for mobilizing agents) International Reporting– Reporting to World Marrow Donor Association (WMDA) when donor orproduct-related: S(P)EAR14

Incident Management IMS: MasterControlTM– Maintained/administered by NMDP Quality Systems– FDA-compliant, configurable software used to report, resolve, monitor,track and trend QIs– Multiple quality management functions Incident captureRemedial actionInvestigationRisk assessmentCorrective Action/Preventative Action (CAPA)NMDP SOPs guide actions– Definitions of events– Process for incident management15International Efforts in Biovigilance in HPCT WMDA: S(P)EAR reporting for donor AEs and productrelated issues– Consolidates data from independent registries:increases power to detect sentinel AE (Shaw, et al, BMT2013)– Mandatory reporting for accredited registries, standardAE definitions and likely attribution16

WMDA SEAR Reporting Serious/unexpected/medically relevant/previously unknownAny serious event or reaction during anesthesia should be reported.Any serious cardiac complication should be reported.Any serious infection should be reported.Any serious mechanical injury should be reported.Any serious incident in hemostasis should be reportedAny serious (late) effect of marrow or PBSC donation should bereported (e.g. autoimmune, malignancy)Any donor death (from 30 post donation; or at any time if thedonation is implicated)17WMDA S(P)EAR Reporting Processing, labeling, handling and transport errors/problems––––––– Wrong stem cell product transfusedWrong stem cell product receivedSerious problems in transportationDamage to bagInadequate cell dose in the stem cell productClotting or other loss of product viabilityContamination leading to serious infection in recipientAny serious unpredicted transmissible infection– HIV, Hepatitis B, Hepatitis C– Any serious unpredicted non-infectious transmissible disease (e.g. malignant)18

WMDA S(P)EAR Committee Review Reporting requirement for accredited WMDA registriesCommittee has international representation with primary review bynon-reporting peersAnnual reports to community by categoryAlmost 300 Cases reported and reviewed in 2016 with determination:––––Donor or product/patient affectedAdditional information requiredAttribution: both that reported and as determined by committeeEducational value for the transplant community 19The Case that Sparked GRIDGRID will replace themany different methodsof identification usedacross the world todaywith a standard,consistent format20
