Clinical
Combining MBMs Multi-Modal Biomarkers and Biomarker Panels
i) Heterogeneity between patients
ii) Heterogeneity between - sensitivity: a) MG number vs function b) proximal vs downstream c) acute vs chronic; TBI symptoms and pathophysiology vary from patient to patient and over time across; therefore, a single biomarker is not sufficient for diagnosis, prognosis, or monitoring
iii) ↑ power (specificity)

- Pooloed: hard to get 3 pooled samples. Is just average acceptable? - Combined decision making? With CSF BM? - Tspo (and other BMs) difference data prerequisite? But the data won't be available in p1b. - What about mab/lab? For phase 2/3? - Intermediate outcome - PoC as "the earliest point in the drug development process at which the weight of evidence suggests that it is 'reasonably likely' that the key attributes for success are present and the key causes of failure are absent" [risk discharge] TE/PE → DR (ePOC) → Interim 이 i) framework 를 명확히 보이고, ii) 왜 ePOC 이 없는지, 왜 datscan/vmat 이 Epoc 이 못 되는지 명확히 보이자. |

Epoc can mean: phase 1, interim ph2, Gray zone: consider other BM Statistical significance: no need, TSPO longi data: needed before ph1b |
