Myeloma outcomes getting better… …but not good enough Kumar et al., Blood 2007 Kumar et al, Leukemia 2011
Why develop early phase trials in the UK? • Improve patient access to novel agents • Provide evidence to develop clinically relevant treatments for the UK • Influence drug development globally • Advance understanding of myeloma and drug resistance • Investigate treatment specific predictors and markers of response/ resistance
An approach to early phase trials Academia Scientific question Pharma Novel drug(s) Clinical Trial Network Early Phase Clinical Trial Biomarker Evaluation Trial Management Biological Markers of Activity

B Cell Receptor Signalling • Ag induced aggregation of BCR – recruitment of SYC • SYC phosphorylates BLNK – BTK – CARD11 • CD19 activates PI3K • Result activation of survival pathways Young & Staudt, Nature Reviews Drug Discovery 12, 229-243 (March 2013)

Ibrutinib & Myeloma • directly inhibit tumor growth • directly inhibit osteoclastic bone resorption, • inhibit the release of osteoclast-derived tumor growth factors • prevent adhesion to bone marrow stromal cells (BMSCs) and release of BMSC-derived growth factors.

Ibrutinib Combinations • MYD88 L265P mutations cooperate with CD79B mutations to enhance BCR signaling addiction • ABC DLBCLs with CARD11 mutations or MYD88 L265P without CD79B mutation resist ibrutinib Yang, Y. et al. Cancer Cell 2012
Summary • Number of early phase myeloma studies in UK • Mix of commercial and academically sponsored • Novel drug access to patients improving • To be globally competitive: • Crucial to maintain innovative pipeline • Meet ambitious recruitment targets • Improve trial set up times
