"We have entered 2024 with strong momentum across our business, including compelling preliminary overall survival data from our ADC combination study in metastatic TNBC, accelerating COSELA sales volume in the most recent quarter, and awaiting near-term data from our 1L TNBC pivotal study for trilaciclib," said Jack Bailey, Chief Executive Officer of G1 Therapeutics. "We believe the initial OS results from our ADC trial may serve as proof-of-concept for the potential of trilaciclib to improve overall survival in combination with the growing class of TROP2 ADCs across TNBC indications and beyond. More imminently, we look forward to the interim OS analysis of our pivotal 1L TNBC trial, which has the potential to transform treatment for women living with this aggressive and difficult-to-treat cancer."

The update includes the following:

Clinical

Initial efficacy results from ongoing Phase 2 ADC trial suggest improved OS among patients receiving trilaciclib in combination with a TROP2 ADC: Preliminary data from the ongoing Phase 2 trial of trilaciclib in combination with the ADC sacituzumab govitecan (SG) in metastatic TNBC patients suggests clinically meaningful improvements in OS among patients receiving trilaciclib in combination with SG compared to SG alone based on historical data from the ASCENT trial, including (1) current median OS of 17.9 months with trilaciclib vs 12.1 months for SG alone and (2) estimated 12-month survival of 59% of patients receiving trilaciclib in combination with SG, which would be a ~20% improvement over SG alone. The Company expects to provide updated OS data from this study mid-2024.
Interim OS analysis of ongoing 1L TNBC pivotal trial expected in 1Q24: This Phase 3 trial builds upon the clinically meaningful and statistically significant OS results demonstrated in the previous Phase 2 TNBC trial. Achievement of the OS endpoint would enable global regulatory submissions.
OS continues to improve over time for Phase 2 TNBC patients receiving subsequent anti-cancer therapy (SACT): Among patients receiving SACT after conclusion of study drug in the previous Phase 2 TNBC trial, the OS benefit in the trilaciclib arm increased over time as patients received SACT. Patients in the trilaciclib arms receiving subsequent 2L+ chemotherapy exhibited a median OS of 14.0 months from start of SACT, compared to patients in the chemotherapy arm receiving subsequent 2L+ chemotherapy of 5.8 months (p=0.001). The median OS of 14.0 months in the trilaciclib arms also compares favorably to historical 2L+ benchmarks for chemotherapy and SG of 6.7 months and 12.1 months in the ASCENT trial, respectively.
Commercial

Strong COSELA (trilaciclib) volume growth in 4Q23: COSELA vial volume grew 19% in 4Q23 over the prior quarter as platinum-based chemotherapy shortages began to abate. COSELA vial volume in October, November, and December 2023 represented the highest volume months since launch.
High levels of satisfaction with COSELA: Up to 91% of prescribing oncologists and nurse practitioners / physician assistants rate satisfaction with COSELA as "very high" primarily driven by fewer hospitalization and protection of multiple cell lineages, which is also supported by real-world evidence.
Corporate

Global opportunities in TNBC expected to be pursued through partnerships: If positive, the Phase 3 1L TNBC OS results would be expected to support regulatory submissions and enable reimbursement in territories outside of the U.S. to drive global expansion through future partnerships.
Cash runway to extend into 2025: The Company expects approximately $82M in cash, cash equivalents, and marketable securities as of December 31, 2023, and a >30% decrease in 2023 operating expenses compared to that of 2022.

"We enter 2024 with several important milestones ahead of us. We anticipate data from our Phase 1 combination study of FHD-286 in AML in the second half of the year and look forward to continued progress with our unique pipeline, including our BRM selective inhibitor and degrader programs in collaboration with Loxo@Lilly," said Adrian Gottschalk, President and Chief Executive Officer. "We have made significant progress with our preclinical programs, including our selective EP300, CBP and ARID1B degrader programs and are getting ready to share more preclinical data in the first half of the year. This will also include preclinical combination data of FHD-286 with tyrosine kinase inhibitors of EGFR and KRAS. Over the next four years, we anticipate the filing of at least six new INDs, reflecting the productivity of our precision medicine platform. This is all supported by our cash and equivalents position of approximately $259.9 million as of September 30, 2023."

-FHD-286. FHD-286 is a potent, selective inhibitor of the BRG1 and BRM subunits of the BAF chromatin remodeling complex where dependency on BRG1/BRM is well-established preclinically with multiple tumor types, including acute myelogenous leukemia (AML)/myelodysplastic syndrome (MDS), non–small cell lung cancer (NSCLC) and prostate cancer.

oAML Update. Foghorn commenced a Phase 1 study 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. The first clinical data are expected in the second half of 2024.
oTKI Resistance. Recently published data, along with Foghorn’s work, suggest that FHD-286 may play an important role in overcoming resistance in EGFR/KRAS tumors. The company is conducting preclinical work to further explore the opportunity.

-Differentiated Pipeline Advancement. Foghorn continues to expand its platform and pipeline. The Company anticipates the potential for six new investigational new drug (IND) applications in the next four years. The Company continues to progress programs for multiple targets that include chromatin remodeling complexes, transcription factors, helicases and other chromatin-related factors. These targets include selective BRM* and wholly owned programs including CBP, EP300, and ARID1B, as well as other undisclosed targets, which combined could address more than 20 tumor types impacting more than 500,000 new patients annually.
oSelective EP300 and Selective CBP programs. Foghorn presented new preclinical data for its EP300 and CBP selective degrader programs at Hanson Wade’s 6th Annual Targeted Protein Degradation Summit on October 31, 2023.
EP300 selective degraders showed potent cellular antiproliferation and in vivo tumor growth inhibition in an AR+ enzalutamide prostate in vivo model.
CBP selective degraders demonstrated significant tumor growth inhibition in a colorectal cancer in vivo model. Antiproliferative effects were also observed for numerous cancer cell lines, including colorectal, gastric and bladder cancers.
At preclinical efficacious doses, neither the EP300 nor the CBP selective degraders caused thrombocytopenia, a commonly observed safety liability for dual CBP/EP300 inhibitors.
Additional preclinical data will be presented in the first half of 2024.
-*Loxo@Lilly Collaboration. Foghorn is engaged in a strategic collaboration with Loxo@Lilly and continues to advance the BRM selective inhibitor and degrader programs along with other undisclosed programs.
-Strong Balance Sheet and Cash Runway. As of September 30, 2023, the Company had $259.9 million in cash, cash equivalents and marketable securities providing cash runway into the first half of 2026.
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.

Fate Therapeutics Announces Initiation of Phase 1 Clinical Trial for FT825 / ONO-8250 in Patients with HER2-expressing Advanced Solid Tumors

On January 8, 2024 Fate Therapeutics, Inc. (NASDAQ: FATE), a clinical-stage biopharmaceutical company dedicated to bringing a first-in-class pipeline of induced pluripotent stem cell (iPSC)-derived cellular immunotherapies to patients with cancer and autoimmune disorders, reported the initiation of enrollment for its Phase 1 clinical trial of FT825 / ONO-8250, a multiplexed-engineered, chimeric antigen receptor (CAR) T-cell product candidate targeting human epidermal growth factor receptor 2 (HER2) (Press release, Fate Therapeutics, JAN 8, 2024, View Source [SID1234639076]). The iPSC-derived CAR T-cell product candidate incorporates a novel HER2-targeted antigen binding domain and is designed to overcome unique challenges in treating solid tumors. The Phase 1 study of FT825 / ONO-8250 is being conducted under a strategic collaboration with Ono Pharmaceutical Co., Ltd. (Ono).

"Since the formation of our partnership with Ono in 2018, we have worked closely together to pioneer the manufacture of CD8 alpha-beta T cells from iPSCs and to discover and integrate novel synthetic controls of cell function into our iPSC-derived CAR T-cell product platform for safe and effective treatment of solid tumors, including functional elements designed to promote cell trafficking, resist immune suppression in the tumor microenvironment, and preferentially target cancer cells," said Scott Wolchko, President and Chief Executive Officer of Fate Therapeutics. "The preclinical data for FT825 / ONO-8250 indicate a highly-differentiated therapeutic profile across a broad range of solid tumors, with the novel HER2-targeted antigen binding domain demonstrating selective targeting of cancer cells expressing HER2 including those with low expression. We are excited to initiate the Phase 1 study in collaboration with Ono and assess the potential to benefit patients with hard-to-treat advanced solid tumors who currently have limited treatment options."

Designed using the Company’s iPSC Product Platform, FT825 / ONO-8250 incorporates seven novel synthetic controls of cell function including a CXCR2 receptor to promote cell trafficking, a chimeric TGFβ receptor to redirect immunosuppressive signals in the tumor microenvironment, and a high-affinity, non-cleavable CD16a receptor to enable antibody-dependent cellular cytotoxicity. Preclinical data of FT825 / ONO-8250 presented at the 2023 Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) Annual Meeting demonstrated that the profile of the novel HER2-targeted antigen binding domain is unique and differentiated from that of trastuzumab, exhibiting similar potency with greater specificity for cancer cells expressing HER2.

The Phase 1 study is designed to investigate a single dose of FT825 / ONO-8250 as monotherapy and in combination with monoclonal antibody therapy in previously-treated patients with advanced solid tumors. The dose escalation and dose expansion portions of the trial are expected to evaluate safety, tolerability, and pharmacokinetics as well as anti-tumor activity by overall response rate, duration of response and disease control rate.

Under the terms of its Collaboration and Option Agreement with Ono, Fate will jointly develop and commercialize FT825 / ONO-8250 with Ono in the U.S. and Europe, and Ono maintains exclusive development and commercialization rights for FT825 / ONO-8250 in the rest of the world. Fate is eligible to receive clinical, regulatory and commercial milestone payments as well as tiered royalties on net sales outside of the United States and Europe by Ono. The parties are currently conducting preclinical development of an additional solid tumor program targeting an undisclosed tumor-associated antigen.
