CAMBRIDGE, Mass., May 06, 2024 (GLOBE NEWSWIRE) -- Foghorn® Therapeutics Inc. (Nasdaq: FHTX), a clinical-stage biotechnology company pioneering a new class of medicines that treat serious diseases by correcting abnormal gene expression, today provided a financial and corporate update in conjunction with the Company’s 10-Q filing for the quarter ended March 31, 2024. With an initial focus in oncology, Foghorn’s Gene Traffic Control® Platform and resulting broad pipeline have the potential to transform the lives of people suffering from a wide spectrum of diseases.
“We are excited about the progress and strength of data presented this quarter which includes robust preclinical anti-tumor monotherapy activity at tolerable doses for multiple pipeline programs. We believe these data demonstrate the potential of our platform to generate novel medicines against very challenging targets, as well as our leadership in the development of therapeutics in chromatin biology," said Adrian Gottschalk, President and Chief Executive Officer of Foghorn.
Mr. Gottschalk added, “In the second half of the year, we expect initial data from our FHD-286 combination study in AML. The IND for FHD-909 was recently submitted and would be the first selective BRM inhibitor to enter the clinic, with a Phase 1 trial planned to begin in the second half of this year. Earlier this year, we also shared data from our Selective CBP degrader program demonstrating tumor growth inhibition in solid tumors without thrombocytopenia or anemia that have been observed with dual CBP/EP300 inhibition. Our Selective EP300 degrader program also demonstrated promising preclinical efficacy with no thrombocytopenia, which is often seen in dual approaches. Our cash balance remains strong, and with multiple programs advancing, we are expected to deliver near- and mid-term value for both patients and shareholders.”
Corporate Updates

Mr. Humer joins Foghorn with over 14 years of diversified financial strategy and business development experience in the life science industry and more than 20 years of experience in the financial industry.
Key Recent Program Updates and Upcoming Milestones
FHD-286. FHD-286 is a potent, selective inhibitor of the BRG1 (SMARCA4) and BRM (SMARCA2) subunits of the BAF chromatin remodeling complex where dependency on BRG1/BRM is well-established preclinically with multiple tumor types, including acute myeloid leukemia (AML)/myelodysplastic syndrome (MDS), non-small cell lung cancer (NSCLC) and prostate cancer.
- AML Update. Foghorn initiated a Phase 1 trial of FHD-286 in combination with decitabine or low-dose cytarabine (LDAC) in relapsed and/or refractory AML patients, with the first patient dosed during the third quarter of 2023. Dose escalation is ongoing with initial clinical data expected in the second half of 2024 .
- Tyrosine Kinase Inhibitor Resistance. Data published in Cancer Cell in August 2023, along with Foghorn’s work, suggest that FHD-286 may play an important role in overcoming and delaying resistance in EGFR/KRAS tumors. Preclinical data is expected in the second quarter of 2024.
FHD-909. FHD-909 is a first-in-class oral BRM (SMARCA2) selective inhibitor that has been demonstrated in preclinical studies to have high selectivity over its closely related paralog BRG1 (SMARCA4), two proteins that are the catalytic engines across all forms of the BAF complex. BRG1 mutations are common across tumor types, including approximately
- In December 2021, Foghorn announced a strategic collaboration with Lilly to create novel oncology medicines. The collaboration includes a US 50/50 co-development and co-commercialization agreement for Foghorn’s Selective BRM oncology program and an additional undisclosed oncology target. In addition, the collaboration includes three discovery programs using Foghorn’s proprietary Gene Traffic Control platform.
- In the first quarter of 2024, Lilly selected FHD-909 for clinical development and in April the investigational new drug (IND) application was submitted. The primary target patient population is BRG1-mutated NSCLC.
- In April 2024, Foghorn and Lilly presented new preclinical data as a poster presentation at the AACR Annual Meeting demonstrating, at tolerable doses, high BRM selectivity and dose-dependent single agent activity in BRG1-mutated cancers.
- Dosing of first patient in Phase 1 trial for FHD-909 in BRG1-mutated NSCLC is expected in the second half of 2024.
Selective CBP Degrader Program and Selective EP300 Degrader Program. Foghorn is advancing two separate programs targeting either CBP or EP300, both of which are paralog histone acetyltransferases with a synthetic lethal relationship in tumor cells. Attempts to selectively drug CBP or EP300 have been historically challenging due to the high level of similarity between the two proteins. Additionally, dual inhibition of CBP/EP300 is limited by hematopoietic toxicity.
- Selective CBP Degrader Program. In April, Foghorn presented new pharmacodynamic and pharmacokinetic preclinical data at the 2024 AACR Annual Meeting highlighting:
- Deep and sustained CBP degradation significantly inhibited tumor growth in mouse xenograft solid tumor models.
- Robust monotherapy preclinical anti-tumor activity that was not associated with significant body weight loss, thrombocytopenia or anemia.
- Identification of potent and selective CBP protein degraders with first-in-class potential to address tumors harboring EP300 mutations in many types of cancer, including bladder, gastric and endometrial cancers.
- Long-acting CBP-selective protein degrader formulations with first-in-class potential for patients with tumors harboring EP300 mutations.
- IND-enabling studies on track to initiate by year-end 2024.
- Selective EP300 Degrader Program. In April, Foghorn presented new pharmacodynamic and pharmacokinetic preclinical data at the 2024 AACR Annual Meeting highlighting:
- No observed thrombocytopenia in vivo.
- Identification of potent and selective EP300 protein degraders with first-in-class potential to address tumors harboring CBP mutations and tumors with dependency on EP300 in several types of cancer, including prostate, multiple myeloma and diffuse large B cell lymphoma (DLBCL).
Selective ARID1B Degrader Program. ARID1A is the most mutated subunit in the BAF Complex and amongst the most mutated proteins in oncology. These mutations lead to a dependency on ARID1B, in several types of cancer, including ovarian, endometrial, colorectal and bladder. Attempts to selectively drug ARID1B have been challenging because of the high degree of similarity between ARID1A and ARID1B and the fact that ARID1B has no enzymatic activity to target.
- In April, Foghorn presented data at the AACR Annual Meeting demonstrating potent and selective small molecule binders to ARID1B. The Company is in the process of converting these selective binders into heterobifunctional degraders.
Drug Discovery Platform. Foghorn's synthesis of deep chromatin expertise, protein biochemistry and screening, and degrader expertise uniquely positions the Company to successfully drug historically challenging targets.
- Potential for five additional INDs in the next four years.
- Targets combined have the potential to address more than 20 tumor types impacting over 500,000 new patients annually.

About FHD-286
FHD-286 is a potent, selective, allosteric, and orally available small-molecule, enzymatic inhibitor of BRG1 (SMARCA4) and BRM (SMARCA2), two highly similar proteins that are the ATPases, or the catalytic engines, of the BAF complex, one of the key regulators within the chromatin regulatory system. In preclinical studies, FHD-286 has shown anti-tumor activity across a broad range of malignancies including both hematologic and solid tumors.
About AML
Adult acute myeloid leukemia (AML) is a cancer of the blood and bone marrow and the most common type of acute leukemia in adults. AML is a diverse disease associated with multiple genetic mutations. It is diagnosed in about 20,000 people every year in the United States.
About FHD-909
FHD-909 (a.k.a. LY4050784) is a potent, allosteric and orally available small molecule that selectively inhibits the ATPase activity of BRM (SMARCA2) over its closely related paralog BRG1 (SMARCA4), two proteins that are the catalytic engines across all forms of the BAF complex, one of the key regulators of the chromatin regulatory system. In preclinical studies, tumors with mutations in BRG1 rely on BRM for BAF function. FHD-909 has shown significant anti-tumor activity across multiple BRG1-mutant lung tumor models.
