Eli Lilly and Company / Loxo Oncology, Inc.

2019 · Acquisition/Merger · $8.0B · Complete

An $8B bet on precision oncology's future. Lilly acquired Loxo to get Vitrakvi, the first tumor-agnostic TRK inhibitor, and selpercatinib (Retevmo), a best-in-class RET inhibitor. The deal also carried LOXO-305, later launched as Jaypirca (pirtobrutinib), the first non-covalent BTK inhibitor. The thesis was validated as Retevmo (FDA-approved 2020, tumor-agnostic 2024) and Jaypirca (2023; CLL/SLL indication expanded Dec 2025) both reached market, though Retevmo remains a modest seller (~$364M in 2024) given the rarity of RET-driven cancers.

Eli Lilly acquired Loxo Oncology for approximately $8 billion ($235 per share) in an all-cash tender offer, gaining a precision oncology pipeline anchored by Vitrakvi (larotrectinib), the first tumor-agnostic TRK inhibitor approved by the FDA, and the RET inhibitor selpercatinib (LOXO-292).

Key facts

Disease & market context

B-Cell Malignancies (BTK)

50K US cases/yr · $15.0B Global BTK Inhibitor Market (2024)

Disease Overview

BTK inhibitors have transformed B-cell malignancy treatment. Jaypirca (pirtobrutinib), acquired via Loxo, is a non-covalent (reversible) BTK inhibitor that works after covalent BTK inhibitor failure, addressing a critical unmet need in CLL and MCL.

Competitive Landscape

Covalent BTKi: Imbruvica (AbbVie/J&J, declining), Calquence (AZ), Brukinsa (BeiGene, fastest growing). Non-covalent BTKi: Jaypirca (Lilly) addresses resistance to covalent agents. BTK degraders (NX-2127, NX-5948 from Nurix; ARQ 531 from Merck/ArQule) represent next wave. The BTK market exceeds $15B globally.

RET-Altered Cancers

15K US cases/yr · $1.5B Global RET Inhibitor Market (2024)

Disease Overview

RET alterations (fusions and mutations) drive ~1-2% of NSCLC, ~10-20% of thyroid cancers, and rare occurrences in other tumor types. Retevmo (selpercatinib) was the first selective RET inhibitor, achieving blockbuster status at $800M. RET testing is increasingly integrated into standard molecular profiling.

Competitive Landscape

Retevmo (Lilly) dominates the RET market. Gavreto (pralsetinib, Roche/Blueprint) was the second approved selective RET inhibitor but was voluntarily withdrawn from US market. Next-gen agents target acquired resistance mutations (RET G810 solvent front mutations). The addressable patient population continues to grow with expanded testing.

NTRK Fusion-Positive Solid Tumors

3K US cases/yr · $800M Global NTRK Inhibitor Market (2024)

Disease Overview

NTRK gene fusions occur in <1% of common cancers but up to 90% of rare tumors like secretory breast carcinoma and infantile fibrosarcoma. Vitrakvi (larotrectinib) was the first tumor-agnostic TRK inhibitor, representing precision oncology's paradigm of treating by molecular target rather than tumor site.

Competitive Landscape

Vitrakvi (Lilly/Loxo) and Rozlytrek (Roche/entrectinib) are the two approved TRK inhibitors. Vitrakvi is more selective; Rozlytrek also covers ROS1. Next-gen TRK inhibitors (selitrectinib, repotrectinib) address acquired resistance. The small eligible population limits commercial potential but validates precision oncology.
