Description: Galunisertib, also known as LY2157299, is a novel, selective small molecule transforming growth factor beta receptor (TGF-βR) kinase inhibitor. LY2157299 inhibited HCC cell migration on Laminin-5, Fibronectin, Vitronectin, Fibrinogen and Collagen-I and de novo phosphorylation of pSMAD2. LY2157299 inhibited HCC migration and cell growth independently of the expression levels of TGF-βRII.

More Info: LY2157299 is a novel selective small molecule transforming growth factor beta receptor (TGF-βR) kinase inhibitor. LY-2157299 could inhibit TGF-β-mediated SMAD2 activation and hematopoietic suppression in primary hematopoietic stem cells. Furthermore, in vivo administration of LY-2157299 ameliorated anemia in a TGF-β overexpressing transgenic mouse model of bone marrow failure. Most importantly, treatment with LY-2157199 stimulated hematopoiesis from primary MDS bone marrow specimens. These studies demonstrate that reduction in SMAD7 is a novel molecular alteration in MDS that leads to ineffective hematopoiesis by activating of TGF-β signaling in hematopoietic cells. These studies also illustrate the therapeutic potential of TBRI inhibitors in MDS. (source: Cancer Res. 2011 Feb 1;71(3):955-63. Epub 2010 Dec 28. ).    

Biological target: TGF-β receptor type I (TGF-βRI) kinase inhibitor with an IC50 of 56 nM.
In vitro activity: The combination of a small molecule inhibitor of TGF-β receptor I, Galunisertib, and CAR T cells was used to explore whether Galunisertib could enhance CAR T cell function against solid tumor cells. In vitro experiments showed Galunisertib could significantly enhance the specific cytotoxicity of both CD133- and HER2-specific CAR T cells. However, Galunisertib had no direct killing effect on target cells. Galunisertib significantly increased the cytokine secretion of CAR T cells and T cells that do not express CAR (Nontransfected T cells). Galunisertib did not affect the proliferation of T cells, the antigen expression on target cells and CD69 on CAR T cells. It was found that TGF-β was secreted by T cells themselves upon activation, and Galunisertib could reduce TGF-β signaling in CAR T cells.

In vivo activity: The in vivo antitumor efficacy of galunisertib was evaluated using a dose of 75 mg/kg administered twice daily by oral gavage, the dosing schedule defined by the PK/PD profile described in the pSMAD inhibition assays (Figure (Figure4).4). Monotherapy anti-tumor activity of galunisertib was evaluated in three independent models; the immune competent 4T1 syngenic murine breast cancer model, the MX1 human xenograft breast cancer model, and the Calu6 human xenograft lung cancer model. In each of these established tumor models, galunisertib monotherapy resulted in significant tumor growth delay (Figure 7A, 7B, 7C, and and7D).7D). For MX1, galunisertib monotherapy resulted in tumor growth delay of 10.3±4.3 days (1500 mm3 crossing time, p = 0.014) (Figure (Figure7A)7A) and for Calu6 galunisertib monotherapy resulted in tumor growth delay of 8.3 +/− 2.6 days (500 mm3 crossing time, p = 0.034) (Figure (Figure7B);7B); for 4T1, galunisertib monotherapy resulted in a tumor growth delay of 13±2.4 days (500 mm3 crossing time, p < 0.01 by repeated measures analysis) and a survival advantage of 4.5 days (p = 0.01) (Figure 7C, 7D), demonstrating the antitumor activity of the compound in traditional preclinical tumor models.
