New Organizational Models for Optimal Cell Processing and Application Robert D. Simari Chair, Cardiovascular Research Professor of Medicine Madrid 2009
NHLBI Working Group onTranslation of Cardiovascular Cell Based Therapies 2005 …the primary recommendation of the Working Group is that the NHLBI establish a cardiovascular cell therapy research network consisting of a clinical research network component (5-7 primary sites)…
What is an NIH Clinical Trial Research Network ? • Provides opportunities for collaborative Phase 1-2 studies. • Success in pulmonary medicine. • Extends single center results (NIH or industry based) • Builds infrastucture to do so.
Clinical Center Selection • Expertise in cell therapy • Preclinical studies • Early clinical trials • Ability to recruit subjects in studies of acute and chronic LV dysfunction. • Willingness to prioritize network studies.

January 2007 • Met to select clinical trials to pursue • Criteria • ability to obtain an IND for trial • Likely performed/completed early phase 1 • Without need for more preclinical studies • Demonstrate need for network resources/sites
January 2007 • Acute MI • MHI pilot study (Traverse/Henry) • Broad European experience • Chronic LV dysfunction • Based on THI experience (Perin/Willerson)
Cardiovascular Cell Therapy Research Network (CCTRN) Regulatory hurdles • CCTRN • Protocol development committee • Steering committee • NHLBI • Protocol Review Committee (Dzau) • DSMB (March) • FDA • IND • Sites • IRB • IBC
Cardiovascular Cell Therapy Research Network (CCTRN) • BMCs in Acute anterior MI • TIME • Timing of delivery (d3 vs d7) • Fixed dose, isolation, delivery • Late TIME • Timing 2-3 weeks • BMCs in chronic ischemic LV dysfunction • Biorepository
Cardiovascular Cell Therapy Research Network (CCTRN) Challenges • Who holds the IND (regulatory responsibility)? New or amended? • Cell preparation-central vs local? And how? • Very high, high or moderate risk population? • Biorepository and cell evaluation-central vs local? • ? Placebo and if so blinding? • Global, regional or clinical endpoints?
Acute MI studies • 2000+ pt studied worldwide • Safety parameters well established • Phase 1 human trial ongoing at MHI (Traverse)-now completed • Basis for IND • Many important unanswered questions
TIME and Late TIME Study Rationale • Changing myocardial milieu following AMI may impact on cell delivery retention. • Prior studies had not randomized to different times. • Cell dose varied greatly within and between studies.

PILOT TRIAL - Administration of BMCs Following Acute Myocardial Infarction at Minneapolis Heart Institute • IND: September 2005 • 40 patients with acute anterior MI’s who received PTCA / Stenting of LAD ( 30% < EF <50% ). • Randomized ( 3:1 Active Treatment vs Placebo). • 100 million BMMC (intracoronary infusion). • Serial Cardiac MRI at Baseline, 3, 6, 12 months. • Potential for cross-over at 6 months
PILOT TRIAL - Administration of BMCs Following Acute Myocardial Infarction at Minneapolis Heart Institute • 40 Patients (31M 9 F), 8 NIDDM, Age= 54yrs • 7 IABP, 2 hypothermia • 37/40 received DES • Transplant Day =5±2 days • Average Ischemic Time = 6:30 hrs • Peak CK = 3308, CKMB = 244 • Baseline LVEF (ECHO 1 day p MI) = 37±12% • Baseline LVEF (cMRI, 4 days p MI) = 49±9% • All Patients had severe MVO on cMRI. • CD34+ count was 2%, Viability > 96% Results at AHA ‘09
TIME Study • Large first Ant MI (EF<45%) • Randomized • cells (2) vs placebo (1) • 3 days vs 7 days • 150 million BMMNCs • Stop flow delivery • 120 pts
Late TIME Study • Large first Ant MI (EF<45%) • Randomized • cells (2) vs placebo (1) • 14-21 days • 150 million BMMNCs • Stop flow delivery • 86 pts
TIME and Late TIME Study Endpoints • Regional and global LV function (cMR) • Core evaluation • Clinical endpoints

FOCUS-HF • Two center US study (THI, MHI) • Perin, Willerson, Henry • Randomized delivery of 30M BMMNCs using NOGA • To be presented at AHA 2009 • Basis for new IND
FOCUS rationale-endpoints • Severe ischemic LV dysfunction • Increased dose (100M cells) in multi-center study. • Placebo controlled • Combined Endpoints = SPECT, Echo (LVV), MVO2 (all core assessed) • 86 pts
Cardiovascular Cell Therapy Research Network (CCTRN) • Cells are processed locally using standardized devices. • Release criteria are local. • Blood and BM is shipped to central biorepository • Univ Minnesota (Taylor) • Univ Florida (Cogle)
CCTRN Biorepository The specific aim of the Biorepository is to examine the relationship between cell therapy clinical outcomes and cell characteristics such as phenotype and function. As a core laboratory, the Biorepository will: • provide storage of critical biomaterials from patients enrolled in CCTRN trials; (BM, PB cells, serum) • provide long-term integrity (up to 10 years) of these specimens • provide phenotypic and functional analyses of BM and PB cells on freshly available samples. Central, rigorous, robust and available

Cardiovascular Cell Therapy Research Network (CCTRN) Ongoing Challenges • Declining severity of acute MI in the U.S. • Focus on the very sick (yet first MI) has generated recruitment challenges. • Rapidly changing scientific landscape of stem cells. We should complete all 3 studies in late 2010/early 2011
