Description: TG101209 is a novel and potent JAK2 inhibitor, which induced dose- and time-dependent cytotoxicity in a variety of multiple myeloma (MM) cell lines. The induction of cytotoxicity was associated with inhibition of cell cycle progression and induction of apoptosis in myeloma cell lines and patient-derived plasma cells. Exploring the mechanism of action of TG101209 indicated downregulation of pJak2, pStat3, and Bcl-xl levels with upregulation of pErk and pAkt levels indicating cross talk between signaling pathways. TG101209 , when used in combination with the PI3K inhibitor LY294002, demonstrated synergistic cytotoxicity against myeloma cells.

| Biological target: | TG101209 is a JAK2 inhibitor with IC50 of 6 nM. |
| In vitro activity: | The DU 528, HSD2, PEER, MOLT-4 and Jurkat T-ALL cell lines were treated with TG101209, and cell proliferation was analysed using MTT assay. The IC50s of the cell lines were 2.542 µM (DU528), 0.329 µM (HSD2), 0.612 µM (PEER), 2.893 µM (MOLT-4) and 1.794 µM (Jurkat) (Supplementary Figure 2). Apoptosis was increased in the HSD2 and PEER cell lines in a TG101209 concentration-dependent manner, according to the flow cytometry analysis. The expression of apoptosis-related proteins (Bax, Cleaved PARP, caspase-3 and caspase-9) was determined by Western blotting. The expression levels of Bax and Cleaved PARP were up-regulated by TG101209, while caspase-3 and caspase-9 were down-regulated in both HSD2 and PEER cell lines (Figure 3A). The cell cycle of each cell line was analysed using flow cytometry. After treatment, the cell cycle was arrested mainly at the G2/M phase. The expression of the indicated cell cycle-related proteins (P21, P27, CDK4 and CDK6) was determined by Western blotting. The expression levels of P21 and P27 were up-regulated by TG101209, while those of CDK4 and CDK6 were down-regulated by TG101209 in both the HSD2 and PEER cell lines (Figure 3B). Primary bone marrow cells from T-ALL patients and healthy controls were treated with TG101209 (0, 1, 2, 4, 6, 8, or 10 μM), and cell proliferation was analysed using MTT assay. The IC50s were 0.755um and 1.565 um respectively. (Supplementary Figure 2). Apoptosis was increased in the cells in a TG101209 concentration-dependent manner, according to the flow cytometry analysis. (Figure 3A).

| In vivo activity: | To test the in vivo efficacy of TG101209 in inhibiting JAK2V617F, a mouse model of JAK2V617F-induced hematopoietic disease was used. All the animals in the control group died due to disease progression by day 11. In striking contrast, TG101209 at the highest dose level (100 mg/kg b.i.d.) was effective in treating JAK2V617F-induced disease as there was a statistically significant prolongation of survival in this group (10 days; P<0.02), and the animals in this group were still alive at the previously defined study end point of 10 days past the time of death of the final placebo-treated animal (Figure 6a). The animals at the lower dose levels (that is, 10 or 30 mg/kg b.i.d.) developed disease with the same latency and penetrance as the placebo-treated animals, without evidence of prolongation of survival (Figure 6a). Compared with placebo-treated animals, TG101209-treated animals exhibited a statistically significant, dose-dependent reduction in the circulating tumor cell burden at day +11 (75% GFP+ cells in placebo-treated versus 15% GFP+ cells in 100 mg/kg b.i.d. TG101209-treated animals; P<0.02) (Figure 6b). The clinical benefit of TG101209 in this model correlated with inhibition of JAK2V617F activity in vivo, evident in the marked decrease in STAT-5 phosphorylation demonstrable in splenic tumors, as early as 7 h after administration of a single dose of TG101209 (100 mg/kg) to the affected mice (Figure 6c).
