Ferroptosis escape in AML stem cells uncovered by single-cell profiling and reversed by STAT3/NRF2 inhibition
(ASH 2025)
- "These cells were treated with STAT3 inhibitor C188-9 or STAT3-NRF2dual inhibitor (Brusatol) and the effect on cell proliferation was determined using CCK-8 assay, geneexpression by qPCR, flow cytometry was used for the detection of lipid ROS levels by Bodipy dye andintracellular iron estimation were performed...Moreover, acombination of NRF2-STAT3 inhibitor potentiated the effect of ferroptosis inducers RSL3 and Erastin andenhanced the cytotoxicity in LSCs.Our scRNAseq analysis of enriched AML LSCs revealed and dissected the mechanistic differencesbetween LSCs and non-LSCs...Our findings suggest that promoting ferroptosis is indeed apromising strategy to combat chemoresistance in AML. Therefore, dual targeting of NRF2-STAT3 alongwith ferroptosis inducers hold potential as adjuvant therapy by promoting ferroptosis-mediated celldeath in AML LSCs."

E3 Ubiquitin Ligase TRIM21 Enhances Macrophage-Mediated Bortezomib Resistance By Inducing M2 Polarization in Multiple Myeloma
(ASH 2023)
- "QPCR and WB results showed that the macrophage polarization effect induced by TRIM21 overexpression was reversed after treatment with the STAT3 inhibitor C188-9. Our study shows that TRIM21 is overexpressed in macrophages in patients with relapsed and refractory MM. In addition, TRIM21 induces M2 polarization by activating the JAK-STAT3 pathway, thereby enhancing the protective effect of macrophage on MM cells. These findings provide a new insight into the role of TRIM21 in MM drug resistance and lay an important theoretical foundation for targeting macrophages in MM."

E3 Ubiquitin Ligase TRIM21 Enhances Macrophage-Mediated Bortezomib Resistance By Inducing M2 Polarization in Multiple Myeloma
(ASH 2024)
- "Pre-treatment of macrophages with the JAK-STAT pathway inhibitor C188-9 reversed TRIM21-mediated regulation of macrophage polarization and notably reduced its protective effect on MM cells. Immunoprecipitation and ubiquitination experiments confirmed that TRIM21 interacts with SOCS3, and TRIM21 significantly increases its ubiquitination, thereby reducing SOCS3 protein levels.In summary, our research confirms that TRIM21 induces M2 polarization in macrophages by targeting SOCS3 to activate the JAK-STAT pathway, thereby enhancing its protective effect on MM cells. Targeting TRIM21 could potentially be a strategy to improve MM treatment efficacy."

Tvardi Therapeutics Provides Update on Preliminary Data from Phase 2 REVERT Trial in Idiopathic Pulmonary Fibrosis
(Tvardi Press Release)
- "After reviewing the preliminary safety data and exploratory efficacy results, including changes in Forced Vital Capacity (FVC), the Company concluded that the study did not meet its goals...Preliminary data demonstrated patients’ baseline characteristics were similar across treatment arms, with the exception of percent predicted FVC, which was lower in the placebo-treated patients (70.1%) compared to the TTI-101-treated arms (74.1% and 81.1%, respectively)...Preliminary analysis of exploratory efficacy showed no statistically significant differences between placebo and treatment arms."

Exploring the Role of STAT3 phosphorylation in Mediating Airway Hyperresponsiveness in a Model of Corticosteroid-Resistant Asthma
(ERS 2025)
- "However, the underlying mechanism remained unknown.The STAT3 inhibitor C188-9 effectively led to a reduction in AHR, decreased neutrophil infiltration, and alleviated airway remodeling in OVA- and ozone-induced mice...STAT3 levels in induced sputum from asthmatic patients exhibited correlation with their large- and small- airway function, neutrophil chemotaxis, and neutrophil levels in induced sputum. STAT3 activation, negatively regulated by SOCS3, plays a key role in corticosteroid-resistant airway neutrophilic inflammation and AHR by influencing the secretion of neutrophil chemokines, the activity of GR, and the levels of HDAC2 in airway epithelial cells."

STAT3 Inhibitors Inducing DNA Damage in Multiple Myeloma Cells and Enhancing the Anti-tumor Effects of NK Cells
(IMS 2025)
- "Using CCK-8 to explore the Half-maximal inhibitory concentration (IC50) of STAT3 inhibitor C188-9 in MM cell lines U266 and RPMI-8266... We found STAT3 inhibitor induces apoptosis and DNA damage in MM cells and STAT3 inhibitor combined with PARP1 inhibitor induced apoptosis and DNA damage in MM cells and mediated the high expression of MICA/B in MM cells. What's more, STAT3 inhibitor combined with PARP1 inhibitor induces DNA damage in MM cells, mediates high expression of MICA/B in MM cells, and activates the anti-tumour effect of NK cells."

JAK2/STAT3 Signaling Pathway Modulates Acute Methylmercury Toxicity in the Mouse Astrocyte C8-D1A Cell Line.
(PubMed, Neurochem Res)
- "Our data demonstrated that pharmacological inhibition of STAT3 using AG490 or C188-9 exacerbated MeHg-induced cell death and compromised antioxidant responses. Furthermore, to fully characterize the role of STAT3 in oxidative stress, we used two different antioxidants, N-acetylcysteine (NAC) and Trolox. Conversely, reactive oxygen species (ROS)-scavenging antioxidants partially ameliorated STAT3 activation, suggesting that MeHg-induced STAT3 activation is mediated, at least in part, by mechanisms independent of ROS. Our findings suggest that STAT3 contributes to neuroprotection against MeHg exposure in astrocytes and is, at least in part, regulated by the increase in ROS levels within these cells."

INTRINSIC MECHANISMS OF RESISTANCE TO CDK4/6 INHIBITORS IN LUMINAL METASTATIC BREAST CANCER
(EACR 2025)
- "MTT assays were performed to study cell viability and resistance to CDKi (Palbociclib)...In contrast, inhibited cell models showed reduced phosphorylation levels in STAT3, confirming the inhibitory effect of C188-9... Preliminary data suggest that STAT3 activation induces resistance to CDK inhibitors in HR+/HER2-cells, while its inhibition sensitises these cells to treatment. These findings highlight the potential of STAT3 as a response biomarker and a possible therapeutic target to counteract resistance to CDK inhibitors in this breast cancer subtype."

ROS-Responsive Hydrogel for Localized Delivery of Nampt and Stat3 Inhibitors Exhibits Synergistic Antitumor Effects in Colorectal Cancer Through Ferroptosis Induction and Immune Microenvironment Remodeling.
(PubMed, Adv Sci (Weinh))
- "Intriguingly, mass cytometry time-of-flight (CyTOF) analysis indicates that the combined treatment with FK866 and C188-9 exerts antitumor effects by increasing the infiltration of CD8+ T cells and neutrophils into the tumor, as well as enhancing the expression of immune-regulatory molecules, including IFN-γ, IL-10, and perforin. Thus, this localized treatment not only minimizes systemic adverse effects, but also markedly amplifies antitumor efficacy through the modulation of both tumor cells and the tumor immune microenvironment, representing a promising antitumor treatment strategy."

Tvardi Therapeutics Announces Presentation at the American Thoracic Society 2025 Annual Conference
(Businesswire)
- "Tvardi Therapeutics, Inc...announced that an abstract will be presented at the American Thoracic Society 2025 Annual Conference, which is being held May 16-21 in San Francisco...The abstract highlights the role of STAT3 as a master regulator of idiopathic pulmonary fibrosis (IPF). In preclinical studies, TTI-101, Tvardi’s STAT3 inhibitor, suppressed fibrotic markers which are not addressed with currently approved therapies (nintedanib and pirfenidone)....In addition, ex vivo analysis of human lung slices treated with TTI-101, nintedanib or pirfenidone resulted in greater repression of genes within alveolar fibroblast (key effector cells in fibrosis) with TTI-101 vs current approved therapies. Notably, TTI-101 downregulated genes involved in extracellular matrix production, including collagen genes, which were largely unaffected by nintedanib or pirfenidone."

Targeting STAT3 in combination with epigenetic therapy induces tumor suppressive IL-24 in non-small cell lung cancer
(AACR 2025)
- "Because persistent STAT3 signaling is associated with poor prognosis and promotes cancer cell survival in multiple cancer types, including NSCLC, we treated a panel of 19 human NSCLC cell lines with the STAT3 inhibitor, C188-9, and epigenetic therapy and identified 12 cell lines demonstrating a synergistic reduction in cancer cell proliferation...To test this hypothesis, we treated NSCLC cells with exogenous IL-24 and confirmed epigenetic therapy-induced sensitization to IL-24. In summary, we define STAT3 as an actionable target that synergizes with epigenetic therapy to diminish the ability of NSCLC cells to proliferate and survive in anchorage-dependent and -independent conditions, associated with significant induction of IL-24."
