Protocol

Cell Assay [1]
Cells are incubated for 96 h with a suitable range of concentrations of drug to ensure accurate estimation of the inhibitor concentration required to give 50% growth inhibition (GI50; typically between 0.001-10 μM). Viable cell number is determined by 4 h of incubation with MTS Colorimetric Assay reagent and absorbance measured at 490 nm on a spectrophotometer. Each experiment is carried out in triplicate for each drug concentration and data are presented as geometric means. Sensitivity groupings of GI50 data are <1 μM, 1 to 7 μM, and >7 μM.

Animal Administration [1]
Swiss nude (nu/nu genotype) and severe combined immunodeficient mice are housed in negative-pressure isolators. Experiments are conducted on 8- to 12-wk-old female mice. All human tumor xenografts are established by s.c. injecting 0.1 mL tumor cell suspension (between 4×106 and 9×107 cells) mixed 1:1 with Matrigel, with the exception of LoVo, which does not include Matrigel, and Calu-3, which uses 30% Matrigel. The BT474c cell line is subcloned from the human breast cell line BT474. For the BT474c model, nude mice are implanted with estradiol 0.36 mg 60-d release pellets 24 h before being implanted with tumor cells. In all models, the animal weight and tumor volumes are monitored twice weekly. Group sizes (n=8-17/group) for each xenograft model are determined by power analysis, and randomization occurred when tumors reach the determined size (>0.2 cm3). AZD8931, lapatinib, and gefitinib are suspended in a 1% (v/v) solution of polyoxyethylenesorbitan monooleate (Tween 80) in deionized water. Animals are given AZD8931 (6.25-50 mg/kg), Lapatinib (100 mg/kg), Gefitinib (100-150 mg/kg), or vehicle control once (qd) or twice daily (bid) by oral gavage. The duration of each study is determined by tumor growth characteristics, with studies ending once tumors reach ~1 cm3. Tumor volume and percentage tumor growth inhibition are calculated and statistical analysis of any change in tumor volume is carried out using a standard t test (P value of lower then 0.05 is considered to be statistically significant).

Background on AZD8931 (Sapitinib)

Description:
IC50: AZD8931 showed equipotent, reversible inhibition of EGFR (IC50, 4 nmol/L), erbB2 (IC50, 3 nmol/L), and erbB3 (IC50, 4 nmol/L) phosphorylation in cells
The erbB receptor family is composed of four related receptor tyrosine kinases [epidermal growth factor receptor (EGFR, erbB1), erbB2 (human epidermal growth factor receptor 2, HER2), erbB3 (HER3), and erbB4 (HER4)]. AZD8931 is a novel small-molecule equipotent inhibitor of EGFR, HER2, and HER3 signaling.
In vitro: In a previous in vitro study, the authors investigated the antitumor activity of AZD8931 alone or in combination with paclitaxel using preclinical models of EGFR-overexpressed and HER2 non-amplified IBC cells. Results showed that AZD8931 significantly suppressed cell growth of IBC cells and induced apoptosis of human IBC cells in vitro [2].
In vivo: In a previous study, the authors investigated the antitumor activity of AZD8931 alone or in combination with paclitaxel IBC cells were orthotopically transplanted into the mammary fat pads of immunodeficient mice. AZD8931 was given by daily oral gavage at doses of 25 mg/kg, 5 days/week for 4 weeks. Paclitaxel was subcutaneously injected twice weekly. Results showed that AZD8931 monotherapy inhibited xenograft growth and the combination of paclitaxel + AZD8931 was demonstrably more effective than paclitaxel or AZD8931 alone treatment at delaying tumor growth in vivo in orthotopic IBC models. These results suggest that AZD8931 may provide a novel therapeutic strategy for the treatment of IBC patients with HER2 non-amplified tumors [2].
Clinical trial: A phase I/II clinical trial is conducted to determine if AZD8931 can improve the efficacy of standard chemotherapy for the treatment of advanced breast cancer. This study will be conducted in 2 parts: the first part (phase I) will determine a dose of AZD8931 that can be safely administered with paclitaxel chemotherapy. The second part (phase II) will determine the efficacy and safety of AZD8931 in combination with paclitaxel chemotherapy in breast cancer (https://clinicaltrials.gov/ct2/show/NCT00900627).

Combining AZD8931, a novel EGFR/HER2/HER3 signalling inhibitor, with AZD5363 limits AKT inhibitor induced feedback and enhances antitumour efficacy in HER2-amplified breast cancer models.[Pubmed:26095475]

Int J Oncol. 2015 Aug;47(2):446-54.

The phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) signalling network is frequently de-regulated in breast cancer and has been shown to mediate resistance to anti-HER2 agents. Whilst constitutive activation of this pathway is emerging as a marker of sensitivity to various PI3K pathway inhibitors, activity of these agents in the clinic may be limited by the presence of feedback loops, leading to reactivation of receptor tyrosine kinases, such as HER2/HER3. To determine whether inhibition of HER2 could increase the efficacy of AZD5363, a novel AKT inhibitor, a panel of breast cancer cells was dosed with AZD5363 in combination with AZD8931, an inhibitor of EGFR/HER2/HER3 signalling. We show that the combined treatment resulted in synergistic growth inhibition and enhanced cell death, specifically in the HER2-amplified cell lines. Investigation of the mechanism by western blot analysis revealed that the addition of AZD8931 prevented the induction of HER2/HER3 phosphorylation induced by AZD5363 and resulted in concomitant inhibition of both the PI3K/AKT/mTOR and ERK signalling pathways and induction of apoptosis. Using the HCC1954 xenograft model, which is resistant to trastuzumab, we show that the combination of AZD5363 and AZD8931 is more efficacious than either agent alone, resulting in profound tumour regressions. We conclude that the activity of AZD5363 in HER2-amplified breast cancer cells is enhanced by the addition of AZD8931 and that dual targeting of AKT and EGFR/HER2/HER3 signalling is an attractive treatment option to be explored in the clinic.

NTAK/neuregulin-2 secreted by astrocytes promotes survival and neurite outgrowth of neurons via ErbB3.[Pubmed:27113200]

Neurosci Lett. 2016 May 27;622:88-94.

NTAK (neural- and thymus-derived activator for ErbB kinases), also known as neuregulin-2 (NRG2), is a member of the epidermal growth factor (EGF) family, which binds directly to ErbB3 and ErbB4, and transactivates ErbB2. NTAK/NRG2 is structurally homologous to NRG1. The biological function of NTAK/NRG2 still remains unknown, especially in the nervous system, whereas NRG1 is known to be essential for nervous system function. In the present study, we examined the functions of NTAK/NRG2 secreted from astrocytes to neurons. NTAK/NRG2 was expressed in both neurons and astrocytes, as evidenced by immunohistochemical staining and RT-PCR methods. The conditioned medium (CM) from astrocytes promoted survival and neurite outgrowth of neurons. The CM stimulated phosphorylation of ErbB3 in neurons. When phosphorylation of ErbB3 was blocked by AZD8931, an ErbB3 inhibitor, neuronal survival and neurite outgrowth were reduced. Conversely, canertinib, an ErbB4 inhibitor, did not affect survival or neurite outgrowth of neurons. Survival and neurite outgrowth of neurons were lower in CM of NTAK/NRG2-knockdown astrocytes than in the CM of control astrocytes, whereas the CM of NRG1-knockdown astrocytes had little effect on survival and neurite outgrowth. The present study demonstrated that NTAK/NRG2 secreted from astrocytes bound to ErbB3 on neurons, and promoted neuronal survival and neurite extension in vitro.

EGFR inhibitors identified as a potential treatment for chordoma in a focused compound screen.[Pubmed:27102572]

J Pathol. 2016 Jul;239(3):320-34.

Chordoma is a rare malignant bone tumour with a poor prognosis and limited therapeutic options. We undertook a focused compound screen (FCS) against 1097 compounds on three well-characterized chordoma cell lines; 154 compounds were selected from the single concentration screen (1 microm), based on their growth-inhibitory effect. Their half-maximal effective concentration (EC50 ) values were determined in chordoma cells and normal fibroblasts. Twenty-seven of these compounds displayed chordoma selective cell kill and 21/27 (78%) were found to be EGFR/ERBB family inhibitors. EGFR inhibitors in clinical development were then studied on an extended cell line panel of seven chordoma cell lines, four of which were sensitive to EGFR inhibition. Sapitinib (AstraZeneca) emerged as the lead compound, followed by gefitinib (AstraZeneca) and erlotinib (Roche/Genentech). The compounds were shown to induce apoptosis in the sensitive cell lines and suppressed phospho-EGFR and its downstream pathways in a dose-dependent manner. Analysis of substituent patterns suggested that EGFR-inhibitors with small aniline substituents in the 4-position of the quinazoline ring were more effective than inhibitors with large substituents in that position. Sapitinib showed significantly reduced tumour growth in two xenograft mouse models (U-CH1 xenograft and a patient-derived xenograft, SF8894). One of the resistant cell lines (U-CH2) was shown to express high levels of phospho-MET, a known bypass signalling pathway to EGFR. Neither amplifications (EGFR, ERBB2, MET) nor mutations in EGFR, ERBB2, ERBB4, PIK3CA, BRAF, NRAS, KRAS, PTEN, MET or other cancer gene hotspots were detected in the cell lines. Our findings are consistent with the reported (p-)EGFR expression in the majority of clinical samples, and provide evidence for exploring the efficacy of EGFR inhibitors in the treatment of patients with chordoma and studying possible resistance mechanisms to these compounds in vitro and in vivo.

The precursor N-desmethyl-AZD8931{2-(4-((4-((3-chloro-2-fluorophenyl)amino)-7-methoxyquinazolin -6-yl)oxy)piperidin-1-yl)acetamide} (11b) was synthesized from methyl 4,5-dimethoxy-2-nitrobenzoate or ethyl 4,5-dimethoxy-2-nitrobenzoate and 2-bromoacetamide in 11 steps with 2-4% overall chemical yield. The target tracer [(11)C]AZD8931 {2-(4-((4-((3-chloro-2-fluorophenyl)amino)-7-methoxyquinazolin-6-yl)oxy)piperidin -1-yl)-N-[(11)C]methylacetamide} ([(11)C]11a) was prepared from N-desmethyl-AZD8931 (11b) with [(11)C]CH3OTf under basic condition (NaH) through N-[(11)C]methylation and isolated by HPLC combined with solid-phase extraction (SPE) in 40-50% radiochemical yield based on [(11)C]CO2 and decay corrected to end of bombardment (EOB) with 370-1110GBq/mumol specific activity at EOB.

Use of a genetically engineered mouse model as a preclinical tool for HER2 breast cancer.[Pubmed:26721874]

Dis Model Mech. 2016 Feb;9(2):131-40.

Resistance to human epidermal growth factor receptor 2 (HER2)-targeted therapies presents a major clinical problem. Although preclinical studies have identified a number of possible mechanisms, clinical validation has been difficult. This is most likely to reflect the reliance on cell-line models that do not recapitulate the complexity and heterogeneity seen in human tumours. Here, we show the utility of a genetically engineered mouse model of HER2-driven breast cancer (MMTV-NIC) to define mechanisms of resistance to the pan-HER family inhibitor AZD8931. Genetic manipulation of MMTV-NIC mice demonstrated that loss of phosphatase and tensin homologue (PTEN) conferred de novo resistance to AZD8931, and a tumour fragment transplantation model was established to assess mechanisms of acquired resistance. Using this approach, 50% of tumours developed resistance to AZD8931. Analysis of the resistant tumours showed two distinct patterns of resistance: tumours in which reduced membranous HER2 expression was associated with an epithelial-to-mesenchymal transition (EMT) and resistant tumours that retained HER2 expression and an epithelial morphology. The plasticity of the EMT phenotype was demonstrated upon re-implantation of resistant tumours that then showed a mixed epithelial and mesenchymal phenotype. Further AZD8931 treatment resulted in the generation of secondary resistant tumours that again had either undergone EMT or retained their original epithelial morphology. The data provide a strong rationale for basing therapeutic decisions on the biology of the individual resistant tumour, which can be very different from that of the primary tumour and will be specific to individual patients.
