TRK fusions have been identified across multiple tumor types Trend toward younger patients Consider patients lacking other “common” mutations Lung: EGFR-negative, ALK-negative, ROS1-negative, KRAS-negative Colorectal: KRAS-negative, BRAF-negative GIST: KIT-negative, PDGFR-negative Thyroid: BRAF-negative Panel-based detection available through send-out labs, academic labs, or commercially available NGS kits RNA-based NGS best captures diversity of TRK fusions Key question to ask: how well does the selected approach “cover” TRK fusions? 28 Considerations for Patient Screening

Universally encountered with targeted therapies As of this presentation, no LOXO-101 responder has progressed Most common: mutations that limit drug binding Gatekeeper: ABL-T315I, EGFR-T790M, ALK-L1196M Solvent front: ALK-G1202R, ROS1-G2032R Case reports: two patients with tumor progression after initial response to a different TRK inhibitor in the clinic1,2 Patient 1: NTRK1 G595R (solvent front) + Y667C Patient 2: NTRK3 G623R (solvent front) 29 Russo et al.

LOXO-195: 2nd Generation TRK Inhibitor LOXO-101 “like” Highly potent: nanomolar in cell against TRKA, TRKB, TRKC Highly selective: >1,000x selective over other off targets Excellent drug properties: orally dosed, high exposure, low clearance Structural modeling: should be active against acquired resistance mutations Experimental assays confirm structural insights LOXO-195 active against all acquired resistance mutations identified to date Entering Phase 1 in 2017 30 TRK WT TRK G595R LOXO-101 LOXO-195 LOXO-101 LOXO-195

Conclusions LOXO-101 is a purpose-built, oral, selective and potent TRK inhibitor PK analyses demonstrate very high Cmax (mean levels >IC90) and linear PK with no significant drug accumulation LOXO-101 is well tolerated, with most common adverse events including Grade 1/2 fatigue, constipation, and dizziness; MTD not yet defined LOXO-101 appears broadly active against TRK fusion cancers in this Phase 1 study Significant tumor regression observed in all 6 evaluable patients Confirmed RECIST responses observed in 5 of 6 evaluable patients All TRK fusion patients are currently on study without progression, with the longest patient over one year LOXO-101 Phase 2 basket trial currently enrolling for patients with TRK gene fusions 31
