Background on NVP-ADW742

NVP-ADW742 is a novel inhibitor of IFG-1receptor (IGF-1R) kinase with the IC50 value of 0.17μM [1].

NVP-ADW742 has shown above 16-fold effective function against IGF-1R than insulin receptor (InsR). Furthermore, NVP-ADW742 has also been reported to inhibit other kinases , with the IC50 values of >10μM for HER2, PDGFR, VEGFR-2, or Bcr-Abl p210, and the IC50 values >5μM for c-Kit [1]. Besides, NVP-ADW742 combined with etoposide and carboplatin has been reported to inhibit cell growth and induce cytotoxicity by MTT assay using the small cell lung cancer (SCLC), including H526, H146, WBA and H209 cell lines. In addition, NVP-ADW742 has been revealed to completely inhibit the expression of VEGF mRNA which induced by IGF-I in H526 cells [2].

The insulin-like growth factor-I (IGF-I) receptor kinase inhibitor NVP-ADW742, in combination with STI571, delineates a spectrum of dependence of small cell lung cancer on IGF-I and stem cell factor signaling.[Pubmed:15141010]

Mol Cancer Ther. 2004 May;3(5):527-35.

Stem cell factor (SCF)/Kit and insulin-like growth factor-I (IGF-I)/IGF-I receptor (IGF-IR) autocrine loops play a prominent role in the growth of small cell lung cancer (SCLC). Previous data suggested that IGF-I protects cells from apoptosis induced by STI571, an efficient inhibitor of Kit signal transduction, by activating the critical phosphatidylinositol 3-kinase-Akt pathway. To determine if inhibition of IGF-IR signaling would be therapeutically relevant in SCLC, the activity of a novel kinase inhibitor of IGF-IR, NVP-ADW742 (Novartis Pharma AG, Basel, Switzerland), was characterized. Pretreatment of the H526 cell line with NVP-ADW742 inhibited IGF-IR signaling and growth with IC(50) values between 0.1 and 0.4 micro M. SCF-mediated Kit phosphorylation and Akt activation were inhibited with IC(50) values in the 1-5 micro M range. However, NVP-ADW742 affected neither hepatocyte growth factor-mediated Akt activation nor activity of constitutively active Akt. The therapeutic potential of NVP-ADW742 was assessed by determining its effect on growth of several SCLC cell lines in serum. These studies clearly delineated two populations of cell lines as determined by differential sensitivity to NVP-ADW742. One population, which lacks active SCF/Kit autocrine loops, was inhibited with IC(50) values between 0.1 and 0.5 micro M. A second population, which has active SCF/Kit autocrine loops, was inhibited with IC(50) values in the 4-7 micro M range. When these cell lines were treated with a combination of STI571 and NVP-ADW742, no advantage was seen in the former group, whereas, in the latter group, a clearly synergistic response to the combination was seen when growth, apoptosis, or Akt activation was assessed. These data demonstrate that NVP-ADW742 is a potent and selective IGF-IR kinase inhibitor that can efficiently inhibit the growth of cells that are highly dependent on IGF-I signaling. However, for optimal growth inhibition of SCLC cells with an active SCF/Kit autocrine loop, a combination of a Kit inhibitor (STI571) and an IGF-IR inhibitor (NVP-ADW742) appears to be necessary. These observations suggest that, in tumors in which critical signal transduction pathways can be activated by alternative receptors, optimal therapy may require inhibition of multiple receptors.

The insulin-like growth factor-I receptor kinase inhibitor, NVP-ADW742, sensitizes small cell lung cancer cell lines to the effects of chemotherapy.[Pubmed:15746061]

Clin Cancer Res. 2005 Feb 15;11(4):1563-71.

PURPOSE: Insulin-like growth factor-I (IGF-I) is a potent growth factor for small cell lung cancer (SCLC) in both the autocrine and endocrine context. It also inhibits chemotherapy-induced apoptosis through activation of the phosphatidylinositol 3-kinase (PI3K)-Akt pathway and we have previously shown that inhibition of this signaling pathway enhances sensitivity of SCLC cell lines to chemotherapy. The purpose of this study was to determine whether the novel IGF-I receptor (IGF-IR) kinase inhibitor, NVP-ADW742, sensitizes SCLC cell lines to etoposide and carboplatin, which are commonly used in the treatment of SCLC. EXPERIMENTAL DESIGN: Cell growth in the presence of various combinations of NVP-ADW742, imatinib (STI571; Gleevec/Glivec), and chemotherapeutic agents was monitored using a 3-(4,5 dimethylthiazol-2yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay and analyzed using the Chou-Talalay multiple-drug-effect equation. Induction of apoptosis was assessed using terminal deoxynucleotide transferase-mediated dUTP nick end labeling (TUNEL) and Western blot analysis of procaspase 3 and poly(ADP-ribose)polymerase cleavage. IGF-I-induced vascular endothelial cell growth factor expression was monitored by Northern blot and ELISA. RESULTS: NVP-ADW742 synergistically enhanced sensitivity of multiple SCLC cell lines to etoposide and carboplatin. Maximal enhancement occurred at concentrations of NVP-ADW742 that eliminated basal PI3K-Akt activity in individual cell lines. In the WBA cell line, in which the c-Kit receptor tyrosine kinase is partly responsible for basal PI3K-Akt activity, the combination of NVP-ADW742 and imatinib was superior to NVP-ADW742 alone in sensitizing the cells to etoposide. Enhancement of the sensitivity of SCLC cell lines to etoposide, as determined by MTT assay, correlated closely with sensitization to the induction of apoptosis as measured by TUNEL and caspase activation assays. Treatment with NVP-ADW742 also eliminated IGF-I-mediated expression of vascular endothelial cell growth factor, suggesting that in addition to enhancing sensitivity of SCLC to chemotherapy, this kinase inhibitor could potentially inhibit angiogenesis in vivo. CONCLUSIONS: Inhibition of IGF-IR signaling synergistically enhances the sensitivity of SCLC to etoposide and carboplatin. This enhancement in sensitivity to chemotherapy tightly correlates with inhibition of PI3K-Akt activation. Future SCLC clinical trials incorporating IGF-IR inhibitors alone or in combination with other kinase inhibitors should include assessment of PI3K-Akt activity as a pharmacodynamic end-point.

The insulin-like growth factor-I receptor kinase inhibitor NVP-ADW742 sensitizes medulloblastoma to the effects of chemotherapy.[Pubmed:21455580]

Oncol Rep. 2011 Jun;25(6):1565-71.

Medulloblastoma is the most common malignant tumor of the central nervous system in children. The insulin-like growth factor-I receptor (IGF-IR) is an important growth factor for medulloblastoma. The novel IGF-I receptor (IGF-IR) kinase inhibitor NVP-ADW742 has in vitro activity against tumors. Daoy cells were treated with NVP-ADW742 combined with temozolomide, which is commonly used in the chemotherapy of medulloblastoma. The effects on proliferation were assayed by CCK-8 assay. Cell cycle status and apoptosis were assayed by FACS analysis. The IGF-IR signaling pathway was analyzed by RT2 Profiler PCR arrays and Western blotting. NVP-ADW742 inhibited IGF-IR-mediated proliferation with an IC50 of 11.12 micromol/l. The PCR array data suggested that 14 genes were down-regulated at the mRNA level after NVP-ADW742 treatment. Western blot analysis suggested that NVP-ADW742 induced early suppression of Akt, P38 and GSK-3beta phosphorylation, as well as a decrease in the intracellular levels of PI3K, Akt, P38, GSK-3beta and Bcl-2. Combined with NVP-ADW742 (2 micromol/l), IC50 of Daoy to temozolomide was decreased from 452.12 to 256.81 micromol/l. Cell apoptosis was enhanced from 16.18+/-2.47% to 23.20 +/- 2.80%. G phase arrest was also found in both the temozolomide alone group and the temozolomide combined with NVP-ADW742 group. NVP-ADW742 inhibited the activation of PI3K, Akt, P38 and GSK-3beta caused by temozolomide. NVP-ADW742 enhanced the chemosensitivity of Daoy to temozolomide in vitro, as a potent anti-tumor agent highly selective against IGF-IR.

The insulin-like growth factor-1 receptor kinase inhibitor, NVP-ADW742, suppresses survival and resistance to chemotherapy in acute myeloid leukemia cells.[Pubmed:21141739]

Oncol Res. 2010;19(1):35-43.

Deregulation of insulin-like growth factor-1 receptor (IGF-1R) is closely associated with malignant transformation and tumor cell survival in various cancers. We found that IGF-1R expression level in leukemia cells positively correlated with the percentage of blast in bone marrow from de novo acute myeloid leukemia (AML) patients. Moreover, we showed that NVP-ADW742, a novel small weight molecular inhibitor of IGF-IR, could induce apoptosis in both HL-60 cell line and primary AML blasts. However, no significant alteration of cell cycle was observed in HL-60 cells. Further studies revealed that NVP-ADW742 induced Akt dephosphorylation, which might subsequently induce p38 phosphorylation and decrease antiapoptotic protein Bcl-2 expression in HL-60 cells. Finally, we demonstrated that NVP-ADW742 could synergize with Ara-C to induce the kill in a subset of drug-resistant AML specimens. We suggested that IGF-lR targeting might be therapeutically beneficial for some AML patients.
