This phase II trial tests how well the combination of WP1066 and radiation therapy works in treating newly diagnosed glioblastoma. Glioblastoma is difficult to treat effectively because the cells within the tumor vary widely and are controlled by factors within and around the tumor, requiring multiple approaches to treat the tumor. The study drug WP1066 targets a specific pathway, known as STAT3, which is responsible for promoting tumor growth and causing the body's immune system to avoid attacking the tumor. Radiation therapy prevents glioblastoma from growing. Giving WP1066 with radiation therapy may prevent glioblastoma from growing and prolong survival.

Interleukin(IL)-37 attenuates isoproterenol (ISO)-induced cardiac hypertrophy by suppressing JAK2/STAT3-signaling associated inflammation and oxidative stress

Article

Author: Wang, Pengfei ; Guo, Bingyan ; Guo, Xiaohua ; Zhang, Donglei ; Qian, Yuxing ; Wei, Huiqing ; Yan, Jie

BACKGROUND:

Inflammation and oxidative stress have drawn more and more interest in the realm of cardiovascular disease. In many different disorders, IL-37 acts as an anti-inflammatory and suppressor of inflammation. This study aimed to investigate whether IL-37 could alleviate cardiac hypertrophy by reducing inflammation and oxidative stress.

METHODS:

In vivo, a cardiac hypertrophy model was induced by 14 d of daily isoproterenol (ISO, 30 mg/kg/d) injection, followed by weeks of treatment with recombinant human IL-37 (1000 ng/animal), administered three times weekly. Assessments concentrated on markers of inflammation and oxidative stress, apoptosis, myocardial disease, and cardiac shape and function. In vitro, neonatal rat cardiomyocytes (NRCMs) were subjected to ISO (10 µM) to establish a cardiomyocytes hypertrophy model. Subsequent IL-37 treatment (100 ng/ml) was applied to determine its cardioprotective efficacy and to elucidate further the underlying mechanisms involved.

RESULTS:

Significant cardioprotective benefits of IL-37 were seen (in vitro as well as in vivo), primarily through the reduction of oxidative stress, inflammation, apoptosis, and heart hypertrophy markers. Furthermore, IL-37 treatment was associated with a decrease in JAK2 and STAT3 phosphorylation. It is interesting to note that WP1066, a JAK2/STAT3 inhibitor, exhibited antioxidant and anti-inflammatory properties comparable to IL-37, as well as synergistic effects when mixed with the latter.

CONCLUSION:

ISO-induced cardiac hypertrophy is lessened by IL-37 through the reduction of oxidative stress and inflammation. Additionally, the effects of IL-37 are closely related to inactivation of the JAK2/STAT3 signaling pathway. It is anticipated that IL-37 will one day be used to treat cardiovascular illnesses such as heart hypertrophy.

METTL14-mediated m6A modification upregulated SOCS3 expression alleviates thyroid cancer progression by regulating the JAK2/STAT3 pathway

Article

Author: Zhang, Yaqi ; Zhang, Qiong ; Zhou, Ming ; Tong, Yanchu

Thyroid cancer (TC) is the most common malignant tumor of the head and neck. As a common epigenetic modification in mRNAs, N6-methyladenosine (m6A) modification plays critical roles in biological process of cancers. However, m6A methyltransferase methyltransferase-like 14 (METTL14)-mediated m6A modification and its potential regulatory mechanisms in TC are not fully elucidated. In our study, we observed that METTL14 was decreased in TC tissues and cells. And upregulation of METTL14 induced apoptotic cell death and hampered cell proliferation, epithelial mesenchymal transition (EMT) and tumor growth in vitro and in vivo. Mechanistically, METTL14 increased the expression of suppressor of cytokine signaling 3 (SOCS3) through m6A methylation modification, and knockdown of SOCS3 reversed the inhibitory effect of overexpressing METTL14 on TC tumorigenesis. In addition, METTL14-mediated m6A modification of SOCS3 inactivated the janus kinase 2 (JAK2)-signal transducer and activator of transcription 3 (STAT3) pathway, and in the METTL14-overexpressing TC cells, silencing SOCS3-induced upregulation of cell proliferation, EMT and suppression of apoptosis was reversed by JAK2/STAT3 inhibitor AG490 and WP1066. Together, we indicated that METTL14/m6A/SOCS3/JAK2/STAT3 axis play an important role in the progression of TC.

PDPN/CCL2/STAT3 feedback loop alter CAF heterogeneity to promote angiogenesis in colorectal cancer

Article

Author: Zhao, Zekun ; Fang, Kai ; Xu, Hanzheng ; Yu, Die ; Xu, Ke ; Zhou, Jinzhe

Colorectal cancer (CRC) is one of the common clinical malignancies and the fourth leading cause of cancer-related death in the world. The tumor microenvironment (TME) plays a crucial role in promoting tumor angiogenesis, and cancer-associated fibroblasts (CAFs) are one of the key components of the tumor microenvironment. However, due to the high heterogeneity of CAFs, elucidating the molecular mechanism of CAF-mediated tumor angiogenesis remained elusive. In our study, we found that there is pro-angiogenic functional heterogeneity of CAFs in colorectal cancer and we clarified that Podoplanin (PDPN) can specifically label CAF subpopulations with pro-angiogenic functions. We also revealed that PDPN + CAF could maintain CAF heterogeneity by forming a PDPN/CCL2/STAT3 feedback loop through autocrine CCL2, while activate STAT3 signaling pathway in endothelial cells to promote angiogenesis through paracrine CCL2. We demonstrated WP1066 could inhibit colorectal cancer angiogenesis by blocking both the PDPN/CCL2/STAT3 feedback loop in CAFs and the STAT3 signaling pathway in endothelial cells. Altogether, our study suggests that STAT3 could be a potential therapeutic target for blocking angiogenesis in colorectal cancer. We provide theoretical basis and new therapeutic strategies for the clinical treatment of colorectal cancer.

Company on track for first subject treated in pivotal, adaptive Phase 3 clinical trial (the "MIRACLE" trial) in the first quarter of 2025 Trial designed for possible accelerated approval of Annamycin in combination with cytarabine for the treatment of relapsed or refractory AML HOUSTON, Nov. 12, 2024 /PRNewswire/ -- Moleculin Biotech, Inc., (Nasdaq: MBRX) ("Moleculin" or the "Company"), a late-stage pharmaceutical company with a broad portfolio of drug candidates targeting hard-to-treat tumors and viruses, today announced it has received Institutional Review Board (IRB) approval for its Phase 3 pivotal trial protocol evaluating Annamycin in combination with Cytarabine (also known as "Ara-C" and for which the combination of Annamycin and Ara-C is referred to as "AnnAraC") for the treatment of AML patients who are refractory to or relapsed after induction therapy (R/R AML) (MB-108). This Phase 3 "MIRACLE" trial (derived from Molecul in R/R AML AnnAraC Clinical Evaluation) will be a global trial, including sites in the US. "IRB approval marks an important milestone towards the launch of our MIRACLE pivotal Phase 3 trial of Annamycin in AML patients. Our team is focused on getting clinical trial sites up and running, and we believe we will be in a position to commence enrollment in the first quarter of 2025," commented Walter Klemp, Chairman and Chief Executive Officer of Moleculin. "We have been extremely busy meeting with potential investigators for this study and are highly encouraged by these conversations. The positive feedback from the clinicians on the strength of our data generated to date, along with our alignment with FDA on the strategic design of the MIRACLE study, gives us a high level of confidence as we take these next steps toward potentially bringing a much needed solution to AML patients." The MIRACLE study, subject to appropriate future filings with and potential additional feedback from the FDA and their foreign equivalents, is expected to initially utilize an adaptive design whereby the first 75 to 90 subjects will be randomized in Part A of the trial to receive high dose cytarabine (HiDAC) combined with either placebo, 190 mg/m2 of Annamycin, or 230 mg/m2 of Annamycin, such doses were specifically recommended by the FDA in our end of Phase 1B/2 meeting. At that point, the trial will be unblinded to select the optimum dose for Annamycin. For Part B of the trial, approximately 240 additional subjects will be randomized to receive either HiDAC plus placebo or HiDAC plus the optimum dose of Annamycin. The selection of the optimum dose will be based on the overall balance of safety, pharmacokinetics and efficacy, consistent with the FDA's new Project Optimus initiative. Annamycin currently has Fast Track Status and Orphan Drug Designation from the FDA for the treatment of relapsed or refractory acute myeloid leukemia, in addition to Orphan Drug Designation for the treatment of soft tissue sarcoma.
