2021 · Co-Development · $1.7B · Complete

A costly stumble for Lilly: $300M upfront plus $80M equity ($380M total) for Foghorn's chromatin-regulator platform and lead asset FHD-286, which was paused in AML in January 2022 over a differentiation-syndrome signal.

Eli Lilly (via Loxo Oncology at Lilly) and Foghorn Therapeutics entered a strategic oncology collaboration announced December 13, 2021 (agreement signed December 10, 2021), built on Foghorn's Gene Traffic Control chromatin-regulator platform. Foghorn received $300M cash upfront plus an $80M equity investment ($380M total) and is eligible for up to $1.3B in milestones plus tiered royalties. The pact is structured as a U.S. 50/50 co-development and co-commercialization agreement on Foghorn's selective SMARCA2 (BRM) oncology program and an additional undisclosed oncology target, plus three discovery programs. The collaboration cleared HSR review and became effective in January 2022, when Foghorn received the upfront. The original anchor clinical asset, FHD-286 (a SMARCA2/SMARCA4 dual inhibitor), was paused in AML in January 2022 over a differentiation-syndrome signal and, after the Phase 1 decitabine-combination readout missed Foghorn's internal efficacy threshold, Foghorn discontinued independent FHD-286 AML development on December 16, 2024. The collaboration's lead asset is now FHD-909 (LY4050784), a first-in-class oral selective SMARCA2 inhibitor that dosed its first Phase 1 patient on October 10, 2024 in SMARCA4-mutated solid tumors (NSCLC primary).

Key facts

Disease & market context

BAF Complex-Dependent Solid Tumors (SMARCA4-Mutant; Synthetic Lethality)

30K US cases/yr · $12.0B Global precision oncology small-molecule market (2021) · ~10% NSCLC SMARCA4 mutation rate

Disease Overview

The BAF (BRG1/BRM-associated factor) chromatin remodeling complex is mutated in approximately 20% of all human cancers, with SMARCA4 (BRG1) loss-of-function mutations enriched in lung adenocarcinoma (~10%), small-cell carcinoma of the ovary hypercalcemic type (SCCOHT, near-universal SMARCA4 loss), undifferentiated thoracic SMARCA4-deficient sarcomas (near-universal), and subsets of melanoma, colorectal, gastric, and pancreatic cancers. The therapeutic logic for SMARCA2 (BRM) inhibition is paralog synthetic lethality — SMARCA4-deficient tumors become uniquely dependent on SMARCA2 to maintain BAF complex function, allowing selective tumor cell killing while sparing normal SMARCA4-intact tissue. The U.S. addressable population for SMARCA4-mutant solid tumors is approximately 30,000-50,000 patients annually, with NSCLC (lung adenocarcinoma) representing the largest subset at ~25,000 SMARCA4-mutant cases per year. Foghorn's FHD-286 (Phase 1) and FHD-609 (BRD9 degrader for synovial sarcoma) anchor the lead pipeline; the Lilly collaboration extends Foghorn's chromatin-regulator chemistry into oncology programs that include both BRM (SMARCA2) selectivity and three undisclosed discovery targets, with rare-tumor and synthetic-lethal mechanisms as the commercial wedge.

Competitive Landscape

The chromatin-remodeling oncology landscape is led by EZH2 inhibition (Tazverik/tazemetostat, Epizyme/Ipsen — approved 2020 for epithelioid sarcoma and follicular lymphoma), DOT1L inhibition (pinometostat — discontinued), and emerging selective BRD9 degraders, BRM/SMARCA2 inhibitors, and PRC2 modulators. Foghorn's FHD-286 (selective SMARCA2/SMARCA4 dual inhibitor) is in Phase 1 in uveal melanoma and AML; FHD-609 (BRD9 selective degrader, synovial sarcoma) is in Phase 1; Plexium and Prelude Therapeutics are advancing competing BRM/SMARCA2 selective inhibitors and BRM-targeted PROTAC degraders; Roche/Genentech, AstraZeneca, and Novartis all maintain internal chromatin-regulator programs. The Lilly collaboration positions Foghorn alongside Lilly's broader oncology portfolio (Verzenio, Jaypirca, Retevmo, Cyramza) and gives Lilly optionality across multiple chromatin-regulator MOAs at a fraction of acquisition economics. In January 2022, Foghorn paused FHD-286 dosing in AML following an unexpected differentiation-syndrome safety signal, reactivating in 2023 with revised dosing — a development risk that must be reconciled against the deal's discovery-stage milestone economics.
