MATRICS: Measurement and Treatment Research to Improve Cognition in Schizophrenia Steve Marder, M.D., P.I. Michael Green, Ph.D., Co-P.I. NIMH Project Officer: Wayne Fenton, M.D. NIMH Division Director, DMDBA: Ellen Stover, Ph.D.
Wayne Fenton Science That Matters
MATRICS: Background and Rationale Increasing evidence that cognitive deficits are core features of schizophrenia Increasing support for relationships between cognition and functional outcome in schizophrenia Increasing research focus on the basic studies of neuropharmacology of cognition
Targeting Cognition in Schizophrenia: Why the Bottleneck? l Lack of consensus regarding cognitive targets. l No widely accepted endpoint. l Ambiguity regarding optimal clinical trial design. l No path to FDA approval and labeling (not a DSM entity).
l FDA registration targets DSM disorders l “No fundamental objection to syndrome- based clinical targets (fever, pain, agitation)” l “We will not accept a new clinical endpoint for the convenience of any drug company” l NIMH can use its convening authority as independent scientific entity to define new and valid clinical endpoints FDA Processes Focus Industry Efforts
NIMH – MATRICS Goals and Products l Create Standardized Measure for use in Clinical Trials l Define Optimal Experimental Designs l Establish path to FDA Approval l Attract large pharmaceutical companies to focus efforts on this important clinical target l Success required involvement of: NIMH, FDA, pharmaceutical industry, and academia
Alzheimer’s Dementia compared with Schizophrenia Neuropsychological Deficit Scores From Heaton et al. (1994) Alzheimer’s Disease: substantial impairment in memory retention relative to schizophrenia
MATRICS Principles for Developing Consensus l Consensus should be as broad as possible l Transparency of process l Inclusion of academia, NIMH, industry, FDA, consumer representatives l A priori development of a path to consensus (e.g., RAND Panel, a modified Delphi process) l Management of conflicts of interest
Steps to MATRICS Consensus Cognitive Battery Subgroup of NCC* & survey of experts NCC, based on survey of experts Survey of experts NCC MATRICS Team RAND Panelists NCC, based on ratings of Panelists *NCC: MATRICS Neurocognition Committee **PASS: MATRICS Psychometric and Standardization Study 1. Identify cognitive domains 2. Select key criteria for test selection 3. Solicit nominations for cognitive tests 4. Narrow tests to 6 or less per domain 5. Create data base on criteria for candidate tests 6. Evaluate tests on criteria with RAND Method 7. Select 2-5 tests per domain for beta battery PASS** group NCC and PASS group 8. Psychometric study with beta battery 9. Final battery of 1-3 tests per domain 10. Co-norming of tests on community sample PASS group
Essential Criteria for Consensus Cognitive Battery for Clinical Trials in Schizophrenia Battery: Inclusion of the seven cognitive domains Valid assessment of cognition at the level of all individual major cognitive domains Individual Tests: High test-retest reliability High utility as a repeated measure Demonstrated relationship to functional outcome Demonstrated tolerability and practicality

Norms from MATRICS-Psychometric and Standardization Study (PASS) Kern et al. Am J. Psychiat. 2008
Co-primary (Intermediate) Measure in Addition to Cognitive Performance: “The current position of the FDA is that concurrent change on a co- primary measure of functional outcome will be required for approval of a neurocognitive drug for schizophrenia.” Buchanan et al. Schizophrenia bulletin 2005 Arguments for Community Status as Co-primary: Increase face validity for consumers and clinicians Increase acceptance by consumers and clinicians The ultimate goal is better community functioning Arguments against Community Status Co-primary: Measurement challenges Distance from biological systems (sensitivity to cognitive-enhancing drugs; likely length of time to change) Intervening variables / level of psychosocial support Arguments by analogy (e.g., not needed for hallucinations, depression, Parkinson’s tremor)
Key Linkages for Cognition and Functional Outcome Cognitive Performance Measures Functional Capacity Interview-based Cognitive Assessment Community Outcome Assessment Environment Laboratory Community Clinic Proximal Distal Within individual Interpersonal Less sensitive More sensitive Sensitivity to cognitive drug effects Intermediate
Follow up Activities to MATRICS 1) TURNS: NIMH Sponsored: Clinical trials network for cognition enhancing drugs; TENETS Network (Treatment and Evaluation Network for Trials in Schizophrenia) 2) Negative Symptoms Initiative New negative symptom scale 3) CNTRICS: NIMH Initiative for cognitive neuroscience measures in clinical trials 4) MATRICS-CT: Translation and Co-primary: Industry / Academic Consortium Translation and co-norming of MCCB into other languages for international trials Evaluation of co-primary measures
TURNS Research Sites Sites Columbia University Duke University Harvard / Mass General Nathan Kline Institute University of Maryland UCLA Washington University *
1. Merck (MK-0777) l 4-week trial l GABA A (α2, α3) partial agonist 2. Allon (AL-108) l 8-week trial l 8 amino acid peptide fragment l promotes assembly of microtubles l potentially neuroprotective 3. Novartis (AQW051) l single dose cross-over study l 2-week parallel group study l α7 nicotinic agonist NIMH-TURNS / TENETS Ongoing Clinical Trials
Identify set of cognitive systems and component processes as targets for treatment development in schizophrenia. Delineate psychometric and pragmatic issues relevant to the development of tasks that measure these cognitive systems. Develop specific measures of target cognitive processes that can be implemented as behavioral tasks, as well as non- invasive functional neuroimaging studies.

Validation of Intermediate Measures (VIM) Study: Key Dependent Measures Performance-based measures 1. Test of Adaptive Behavior in Schizophrenia (TABS) 2. UCSD Performance-based Skills Assessment (UPSA) 3. Independent Living Scales (ILS) Each of these performance-based assessments will be administered so that short forms can be compared with long forms. Interview-based measures 1. Semi-structured: Cognitive Assessment Interview (CAI) 2. Global assessment (1-100 pt scale): Global Assessment of Function from CAI 3. Clinical impression (1-7 pt scale): CGI for Cognitive Impairment
