The present disclosure relates to compositions and methods for the treatment of diseases or disorders (e.g., cancer) with inhibitors of the protein tyrosine phosphatase SHP2, alone and in combination with other therapeutic agents such as a RAS pathway inhibitor (e.g., a MEK inhibitor). Specifically, this invention is concerned with methods of treating diseases or disorders (such as cancer) in certain subsets of patients that are determined to be candidates for treatment with a SHP2 inhibitor.
Cancer remains one of the most deadly threats to human health. In the U.S., cancer affects nearly 1.3 million new patients each year, and is the second leading cause of death after heart disease, accounting for approximately 1 in 4 deaths (US20170204187). Many cancers are caused by constitutive or aberrant activation of receptor tyrosine kinases (RTKs) and/or RAS pathway modulators.
RTKs are transmembrane proteins having an extracellular ligand binding domain, a transmembrane domain, and a tyrosine kinase domain. Receptor tyrosine kinases are an important class of receptor that are involved in many fundamental cellular processes including cell proliferation, survival, metabolism, and migration, e.g. Schlessinger, Cell, 103: 211-225 (2000). Prominent families of this class include, for example, epidermal growth factor receptor (EGFR), platelet derived growth factor receptor (PDGFR), erbB2, erbB4, vascular endothelial growth factor receptor (VEGFR), tyrosine kinase with immunoglobulin-like and epidermal growth factor homology domains (TIE-2), insulin growth factor-I (IGFI) receptor, macrophage colony stimulating factor (MCSF), BTK, ckit, cmet, fibroblast growth factor (FGF) receptors, Trk receptors (TrkA, TrkB, and TrkC), ephrin (eph) receptors, hepatocyte growth factor receptors (HGFR) and the RET protooncogene.
The class of receptor tyrosine kinases is so named because when activated by dimerization, the intracellular domain of RTKs acquire tyrosine kinase activity that can, in turn, activate a variety signal transduction pathways.
RAS oscillates between GDP-bound “off” and GTP-bound “on” state, facilitated by interplay between a GEF protein (e.g., SOS1), which loads RAS with GTP, and a GAP protein (e.g., NF1), which hydrolyzes GTP, thereby inactivating RAS. Additionally, the SH2 domain-containing protein tyrosine phosphatase-2 (SHP2) associates with the receptor signaling apparatus and becomes active upon RTK activation, and then promotes RAS activation (id).
Activation of RAS results in induction of the serine/threonine kinase RAF. RAF phosphorylates MEK/2 which in turn phosphorylates and activates ERK1/2 leading to downstream signaling, e.g., via transcription, as well as feedback inhibition of the RTK, thereby turning off transduction of the signal. RAF also activates MAP3 kinases that activate MKK4/7, MKKK3/6 and MEK5, which activates JNK1/2, p38 and ERK5, consecutively. MAP3Ks are also activated by inflammatory cytokines, oxidative stress and UV radiation. PI3K is activated by RTK autophosphorylation and results in the activation of Akt, which also induces mTOR within the mTORC1 complex. Akt is also regulated by mTORC2 complex. PLCγ activation leads to Ca+2 mobilization and to the activation of PKC. These events play an essential role in proliferation, differentiation, survival and cell migration.
Over-expression or mutation of RTKs and/or RAS pathway signaling molecules have been shown to result in uncontrolled cell growth. The aberrant activity of such kinases has been linked to malignant tissue proliferation, survival, invasion and metastasis. For instance, mutations affecting RTKs and/or RAS pathway components Ras (KRAS, NRAS, HRAS), B-Raf, NF1, PI3K and AKT are common in promoting the malignancy of several types of cancers and from different tissue origins.
Accordingly, RTKs and downstream RAS pathway signal transducers represent attractive therapeutic targets.
However, therapeutic inhibition of the RAS pathway, although often initially efficacious, can ultimately prove ineffective as it may lead to over-activation of RAS pathway signaling via a number of mechanisms including, e.g., reactivation of the pathway via relief of the negative feedback machineries that naturally operate in these pathways. For example, in various cancers, MEK inhibition results in increased ErbB signaling due to its relief of MEK/ERK-mediated feedback inhibition of RTK activation. As a result, cells that were initially sensitive to such inhibitors may become resistant. Thus, a need exists for methods of effectively inhibiting RAS pathway signaling without inducing activation of resistance mechanisms.
SHP2 is a non-receptor protein tyrosine phosphatase encoded by the PTPN11 gene that contributes to multiple cellular functions including proliferation, differentiation, cell cycle maintenance and migration. SHP2 is involved in signaling through the RAS-mitogen-activated protein kinase (MAPK), the JAK-STAT and/or the phosphoinositol 3-kinase-AKT pathways.
SHP2 has two N-terminal Src homology 2 domains (N-SH2 and C-SH2), a catalytic domain (PTP), and a C-terminal tail. The two SH2 domains control the subcellular localization and functional regulation of SHP2. The molecule exists in an inactive, self-inhibited conformation stabilized by a binding network involving residues from both the N-SH2 and PTP domains. Stimulation by, for example, cytokines or growth factors acting through RTKs leads to exposure of the catalytic site resulting in enzymatic activation of SHP2.
Mutations in the PTPN11 gene and subsequently in SHP2 have been identified in several human developmental diseases, such as Noonan Syndrome and Leopard Syndrome, as well as human cancers, such as juvenile myelomonocytic leukemias, neuroblastoma, melanoma, acute myeloid leukemia and cancers of the breast, lung and colon. Some of these mutations destabilize the auto-inhibited conformation of SHP2 and promote autoactivation or enhanced growth factor-driven activation of SHP2.
SHP2, therefore, represents a highly attractive target for the development of novel therapies for the treatment of various diseases including cancer. It has been disclosed previously that either the knockdown of SHP2 expression using RNAi technology or inhibition of SHP2 by an allosteric small molecule inhibitor interferes with signaling from various RTKs involved in driving cancer cell growth. However, this work also concluded that such approaches would be ineffective at blocking growth signaling in cells in which growth is driven by mutations in proteins that act downstream of RTKs, such as those containing activating mutations in Ras or Raf proteins (Chen, Ying-Nan P. 148 Nature Vol 535 7 Jul. 2016 at pg. 151).
The present disclosure relates to treating or preventing a disease or disorder (e.g., cancer) with a SHP2 inhibitor alone or in combination with another suitable therapeutic agent. Specifically, in some embodiments, the present disclosure relates to the unexpected discovery that contrary to the teachings of the prior art, certain subsets of cancer cells carrying oncogenic RAS pathway mutations are sensitive to SHP2 inhibition and may be effectively treated with SHP2 inhibitors. In some embodiments, the present disclosure relates to the discovery that certain subsets of cancer cells carrying RAS mutations (e.g., KRASG12C and/or certain other KRAS mutations) are sensitive to SHP2 inhibition. In some embodiments, the present disclosure relates to the discovery that certain subsets of cancer cells carrying NF1LOF mutations are sensitive to SHP2 inhibition.
Accordingly, in various embodiments, the present disclosure provides a method for treating cells (e.g., cancer cells) containing RAS pathway mutations, which render the mutated protein dependent on upstream signaling through SHP2, with an inhibitor of SHP2.
In some embodiments, the present disclosure relates to the unexpected discovery that even though SHP2 activation naturally promotes MAPK signaling, which in turn may promote feedback inhibition of RTK and RAS pathway signaling, inhibition of SHP2 does not result in subsequent over-activation of RTK or RAS pathway signaling via relief of that feedback inhibition. This is particularly surprising given the fact that SHP2 is downstream from the RTKs in the RAS pathway, and SHP2 inhibition blocks transmission of signals from RTKs; thus, the expected outcome of SHP2 inhibition was hyperactivation of RTKs due to feedback disinhibition. Thus, the present disclosure demonstrates that unlike MAPK inhibitors, which may induce resistance by relief of feedback inhibition, SHP2 inhibitors do not, and they are able to attenuate hyperactivation of RAS in response to MEK inhibitor treatment that may contribute to MEK inhibitor drug resistance.
In some embodiments, the present disclosure relates to the discovery that SHP2 inhibition is an effective means for preventing and delaying the emergence of tumor resistance to various cancer therapies and for re-sensitizing a tumor that is resistant to a MAPK inhibitor to that inhibitor.
In some embodiments, the discoveries disclosed herein provide a method for treating cells (e.g., cancer cells) with a SHP2 inhibitor, wherein the cells have been rendered dependent on SHP2 by means of a therapeutic intervention (e.g., administration of a MAPK inhibitor). In some embodiments, such a therapeutic intervention rendering the cells dependent on SHP2 signaling results in overactivation of the RAS pathway via relief of a natural RAS pathway negative feedback mechanism.
In some embodiments, the present disclosure relates to the surprising discovery that contrary to the teachings of the prior art, SHP2 phosphorylation at Y580 occurs after, and is dependent on prior phosphorylation at Y542, and allosteric inhibition of SHP2 activity occurs by stabilizing the closed state of the enzyme, thereby preventing the phosphorylation of Y580, but not Y542.
In some embodiments, the present invention provides a method of determining whether a SHP2 inhibitor has engaged its target (i.e., SHP2), the method comprising determining whether Y542, but not Y580 on SHP2 is phosphorylated in response to growth factor stimulation.
Accordingly, the present invention relates to compositions and methods for treating or preventing diseases or disorders (e.g., cancer) with inhibitors of the protein tyrosine phosphatase SHP2. The present invention also relates to methods of establishing appropriate treatment plans for subjects based upon the expression of one or more biomarker in a tissue sample from the subject, wherein the biomarker is indicative of SHP2 inhibitor sensitivity.

The terms “RAS pathway” and “RAS/MAPK pathway” are used interchangeably herein to refer to a signal transduction cascade downstream of various cell surface growth factor receptors in which activation of RAS (and its various isoforms and alleotypes) is a central event that drives a variety of cellular effector events that determine the proliferation, activation, differentiation, mobilization, and other functional properties of the cell. SHP2 conveys positive signals from growth factor receptors to the RAS activation/deactivation cycle, which is modulated by guanine nucleotide exchange factors (GEFs, such as SOS1) that load GTP onto RAS to produce functionally active GTP-bound RAS as well as GTP-accelerating proteins (GAPs, such as NF1) that facilitate termination of the signals by conversion of GTP to GDP. GTP-bound RAS produced by this cycle conveys essential positive signals to a series of serine/threonine kinases including RAF and MAP kinases, from which emanate additional signals to various cellular effector functions.
The terms “RAS pathway mutation” and “RAS/MAPK pathway activating mutation” are used interchangeably herein to refer to a mutation in a gene encoding a protein directly involved in the signaling processes of the RAS/MAPK signaling pathway and/or regulating (either positively or negatively) this signaling pathway that renders the pathway active, wherein such mutation may increase, change or decrease the activity level of said protein. Such proteins include but are not limited to Ras, Raf, NF1, SOS, and specific isoforms or alleotypes thereof
The term “RTK-driven tumor” refers to a tumor comprising a cell with one or more oncogenic mutation of an RTK, or a protein that is part of the RTK signaling complex, that causes high levels RTK signaling. Some such cells may be considered “addicted” to the RTK, and inhibition of RTK signaling leads to simultaneous suppression of downstream pathways, often resulting in cell growth, arrest, and death. RTK-driven tumors include, but are not limited to, non-small cell lung cancers (NSCLCs) with mutations in EGFR or ALK.
The term “SHP2” means “Src Homolgy-2 phosphatase” and is also known as SH-PTP2, SH-PTP3, Syp, PTP1D, PTP2C, SAP-2 or PTPN11.
The terms “SHP2 inhibitor” and “inhibitor of SHP2” are used interchangeably.
The term “SOS” (e.g., a “SOS mutation”) refers to SOS genes, which are known in the art to include RAS guanine nucleotide exchange factor proteins that are activated by receptor tyrosine kinases to promote GTP loading of RAS and signaling. The term SOS includes all SOS homologs that promotes the exchange of Ras-bound GDP by GTP. In particular embodiments, SOS refers specifically to “son of sevenless homolog 1” (“SOS1”).
Reference to a “subtype” of a cell, (e.g., an NF1LOF subtype, a KRASG12C subtype, a KRASG12S subtype, a KRASG12D subtype, a KRASG12V subtype) means that the cell contains a gene mutation encoding a change in the protein of the type indicated. For example, a cell classified as an “NF1LOF subtype” contains a mutation that results in NF1 loss of function; a cell classified as a “KRASG12C subtype” contains at least one KRAS allele that encodes an amino acid substitution of cysteine for glycine at position 12 (G12C); and, similarly, other cells of a particular subtype (e.g., KRASG12D KRASG12S and KRASG12V subtypes) contain at least one allele with the indicated mutation (e.g., a KRASG12D mutation, a KRASG12S mutation or a KRASG12V mutation, respectively). Unless otherwise noted, all amino acid position substitutions referenced herein (such as, e.g., “G12C” in KRASG12C) correspond to substitutions in the human version of the referenced protein, i.e., KRASG12C refers to a G→C substitution in position 12 of human KRAS.
A “therapeutic agent” is any substance, e.g., a compound or composition, capable of treating a disease or disorder. In some embodiments, therapeutic agents that are useful in connection with the present disclosure include without limitation SHP2 inhibitors, ALK inhibitors, MEK inhibitors, RTK inhibitors (TKIs), and cancer chemotherapeutics. Many such inhibitors are known in the art and are disclosed herein.
The terms “therapeutically effective amount”, “therapeutic dose”, “prophylactically effective amount”, or “diagnostically effective amount” is the amount of the drug, e.g., a SHP2 inhibitor, needed to elicit the desired biological response following administration.
The term “treatment” or “treating” with regard to a subject, refers to improving at least one symptom, pathology or marker of the subject's disease or disorder, either directly or by enhancing the effect of another treatment. Treating includes curing, improving, or at least partially ameliorating the disorder, and may include even minimal changes or improvements in one or more measurable markers of the disease or condition being treated. “Treatment” or “treating” does not necessarily indicate complete eradication or cure of the disease or condition, or associated symptoms thereof. The subject receiving this treatment is any subject in need thereof. Exemplary markers of clinical improvement will be apparent to persons skilled in the art.
The present disclosure relates to, inter alia, compositions, methods, and kits for treating or preventing a disease or disorder (e.g., cancer) with a SHP2 inhibitor alone or in combination with another suitable therapeutic agent.
SHP2 is an important signaling effector molecule for a variety of receptor tyrosine kinases (RTKs), including the receptors of platelet-derived growth factor (PDGFR), fibroblast growth factor (FGFR), and epidermal growth factor (EGFR). SHP2 is also an important signaling molecule that regulates the activation of the mitogen activated protein (MAP) kinase pathway which can lead to cell transformation, a prerequisite for the development of cancer. For example, SHP2 is involved in signaling through the Ras-mitogen-activated protein kinase, the JAK-STAT and/or the phosphoinositol 3-kinase-AKT pathways. SHP2 mediates activation of Erk1 and Erk2 (Erk1/2, Erk) MAP kinases by receptor tyrosine kinases such as ErbB1, ErbB2 and c-Met by modulating RAS activation.
SHP2 has two N-terminal Src homology 2 domains (N-SH2 and C-SH2), a catalytic domain (PTP), and a C-terminal tail. The two SH2 domains control the subcellular localization and functional regulation of SHP2. The molecule exists in an inactive conformation, inhibiting its own activity via a binding network involving residues from both the N-SH2 and PTP domains. In response to growth factor stimulation, SHP2 associates with the RTK signaling apparatus, and this induces a conformational change that results in SHP2 activation.
Activating mutations of SHP2 have been associated with developmental pathologies such as Noonan syndrome and Leopard Syndrome and may also be found in multiple cancer types, including most RTK-driven tumors, leukemia, lung and breast cancer, gastric carcinoma, anaplastic large-cell lymphoma, glioblastoma and neuroblastoma.1 Grossmann, K S, Rosário, M., Birchmeier, C. & Birchmeier, W.

In addition, SHP2 plays a role in transducing signals originating from immune checkpoint molecules, including but not limited to programmed cell death protein 1 (PD-1) and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). In this context, inhibition of SHP2 function may promote activation of immune cells expressing checkpoint molecules, including anti-cancer immune responses.
It has been disclosed previously that either the knockdown of SHP2 expression using RNAi technology or inhibition of SHP2 by an allosteric small molecule inhibitor interferes with signaling from various RTKs involved in driving cancer cell growth. However, this work also concluded that such approaches would be ineffective at blocking growth signaling in cells in which growth is driven by mutations in proteins that act downstream of RTKs, such as those containing activating mutations in Ras or Raf proteins (Chen, Ying-Nan P. 148 Nature Vol 535 7 Jul. 2016 at pg. 151).
Accordingly, in some embodiments, the present disclosure relates to the unexpected discovery that, contrary to the teachings of the prior art, certain subsets of cells carrying certain oncogenic Ras pathway mutations (e.g., KRASG12C mutations) are sensitive to SHP2 inhibition and may be effectively treated with SHIP2 inhibitors (see, e.g., Example 1). For example, the present disclosure demonstrates that certain subsets of cancer cells carrying particular KRAS mutations (e.g., KRASG12C mutations) or NF1LOF mutations are sensitive to SHP2 inhibition and that SHP2 inhibition is an effective means for preventing and delaying the emergence of tumor resistance to various therapeutic agents including cancer therapies (e.g., MAPK inhibitors) and an effective means for re-sensitizing a tumor that is resistant to a cancer therapy (e.g., a MAPK inhibitor) to that inhibitor, particularly in the context of Ras pathway mutations. Similarly, the present disclosure demonstrates that certain subsets of cancer cells carrying particular BRAF mutations (e.g., Class 3 BRAF mutations) or MEK mutations (e.g., Class 1 MEK1 mutations) are sensitive to SHP2 inhibition and that SHP2 inhibition is an effective means for preventing and delaying the emergence of tumor resistance to various therapeutic agents including cancer therapies (e.g., MAPK inhibitors, MEK inhibitors, Erk inhibitors, etc.) and an effective means for re-sensitizing a tumor that is resistant to a cancer therapy (e.g., a MAPK inhibitor) to that inhibitor, particularly in the context of Ras pathway mutations.
The observation that a SHP2 inhibitor can inhibit some, but not all, KRAS mutant cells may be a function of the nucleotide cycling features of a particular KRAS mutation and its corresponding dependence on signaling inputs to maintain high levels of the active, GTP-bound state. Indeed Patricelli and coworkers have demonstrated that KRASG12C is not a constitutively and fully active protein but rather the nucleotide state of KRASG12C is in a state of dynamic flux that can be modulated by upstream signaling factors (Patricelli et al., Cancer Discov. 2016 March; 6(3):316-29, incorporated herein by reference in its entirety). Similarly, in cells which have lost function of the GTPase activating protein (GAP), e.g. NF1LOF there is a shift towards the active, GTP-bound state of RAS, which drives signaling to RAS effectors and growth addiction. In these cells, the wildtype RAS undergoes nucleotide cycling which, as for KRASG12C makes it sensitive to upstream signaling inputs to maintain a highly active state. In the present disclosure, the sensitivity of KRASG12C and NF1LOF lines to a SHP2 allosteric inhibitor reflects modulation of these upstream factors, and hence the nucleotide state of mutant/WT RAS, by the inhibitor.
Thus the present disclosure provides at least in part, compositions, methods, and kits for the identification, assessment and/or treatment of a disease or condition (e.g., a cancer or tumor such as, for example an oncogene-associated cancer or tumor) responsive to a treatment that includes a SHP2 inhibitor alone or in combination with another cancer therapeutic agent (e.g., an inhibitor of a MAP kinase pathway).
In some embodiments, the present disclosure provides a method for patient stratification based upon the presence or absence of a RAS pathway mutation or based upon the particular subtype of such a mutation. As used herein, “patient stratification” means classifying one or more patient as having a disease or disorder (e.g., cancer) that is either likely or unlikely to be treatable with a SHP2 inhibitor. Patient stratification may comprise classifying a patient as having a tumor that is sensitive to treatment with a SHP2 inhibitor. The patient stratification may be based on the presence or absence of a tumor comprising one or more cell containing a RAS pathway mutation that renders the mutated protein dependent on signaling flux through SHP2. As used herein, the term “at least partially dependent on signaling flux through SHP2” when used in relation to a mutation, e.g., a RAS pathway mutation, refers to a mutation that renders the function of the mutated protein susceptible to modulation by SHP2 and the effects of inhibitors thereof. The RAS pathway mutation may occur in one or more protein selected from KRAS, NRAS, HRAS, ARAF, BRAF, CRAF, SOS, MEK (e.g., MEK1), and NFL The RAS pathway mutation may occur in one or more protein selected from KRAS, NRAS, HRAS, BRAF, SOS, and NH. In particular embodiments, the mutation in KRAS, NRAS, HRAS, BRAF, SOS, MEK (e.g., MEK1) or NF1 renders the mutated protein sensitive to upstream signaling inputs to maintain a highly active state. The upstream signaling inputs may require SHP2. As used herein, the term “sensitive to upstream signaling inputs to maintain a highly active state” means that maintenance of the active state of a protein (e.g., GTP-RAS) requires upstream signaling inputs (e.g., signaling via SHP2), and modulation of these inputs (e.g., by SHP2 inhibition) results in a change of the active state of the protein (e.g., as shown herein, inhibition of SHP2 results in decreased RAS-GTP levels (

In some embodiments, the SHP2 inhibitor is administered to the subject as a monotherapy for the treatment of a tumor. The tumor may contain a RAS pathway activating mutation. In various embodiments, the RAS pathway activating mutation confers cellular dependence on SHP2 (e.g., for reloading of GTP onto RAS).
In certain embodiments, the SHP2 inhibitor is administered to the subject as a monotherapy for the treatment of a tumor comprising a cell that contains an NF1LOF mutation. NF1 is a GAP protein that modulates RAS activation by facilitating hydrolysis of GTP from GTP from active RAS-GTP, thereby inactivating RAS. RAS oscillates between GDP-bound “off” and GTP-bound “on.” Loss of function mutations in NF1 reduce GTP hydrolysis by RAS, and shift the equilibrium toward activated RAS, thereby resulting in cancerous growth/proliferation and possibly oncogene addiction. NF1 mutations occur frequently in NSCLC (e.g., 8.3% per Cancer Genome Atlas Research Network “Comprehensive molecular profiling of lung adenocarcinoma.” Nature 511, 533-550 (2014)), and more than 80% of all constitutional NF1 mutations are NF1LOF (Philpott, 2017), yet no targeted therapies are available for treating NF1LOF subtype tumors. As shown herein, SHP2 inhibition in NF1LOF cells resulted in dose dependent suppression of p-ERK signaling and proliferation (Example 1,
In certain embodiments, the SHP2 inhibitor is administered to the subject as a monotherapy for the treatment of a tumor comprising a cell that contains a mutation in a RAS gene. In certain embodiments, the RAS gene mutation renders the RAS pathway dependent on signaling flux through SHP2. The RAS pathway mutation may be a KRAS, NRAS, or HRAS mutation. Oncogenic RAS mutations, such as KRAS mutations, shift the RAS equilibrium to the GTP-bound “on” state, driving signaling to RAS effectors and oncogene addiction. As used herein, “oncogene addiction” refers to the phenomenon whereby a tumor cell exhibits apparent dependence on a single oncogenic pathway or protein for sustained proliferation and/or survival, despite its myriad of genetic alterations. Treatment of KRAS cell line panels identified certain mutations as biomarkers of growth sensitivity to SHP2 inhibition (Example 1, Table 3). In certain embodiments, the SHP2 inhibitor is administered to the subject as a monotherapy for the treatment of a tumor comprising a cell that contains a KRASG12C mutation.

In certain embodiments, the SHP2 inhibitor is administered to the subject in combination with one or more other therapeutic agent (e.g., an inhibitor of a MAP kinase pathway) as a combination therapy for the treatment of a tumor comprising a cell containing a RAS pathway mutation that renders the mutated protein dependent on signaling flux through SHP2. The mutation may comprise one or more of an NF1LOF mutation; a RAS/RAF mutation; a KRAS mutation; a KRAS mutation selected from a KRASG12A mutation; a KRASG12C mutation; a KRASG12D mutation; a KRASG12S mutation; a KRASG12V mutation; a Class III BRAF mutation; a BRAF mutation selected from D287H; P367R; V459L; G466V; G466E; G466A; S467L; G469E; N581S; N581I; D594N; D594G; D594A; D594H; F595L; G596D; G596R and A762E; a Class I MEK1 mutation; a MEK1 mutation selected from D67N; P124L; P124S; and L177V; a Class II MEK1 mutation; and a MEK1 mutation selected from ΔE51-Q58; ΔF53-Q58; E203K; L177M; C121S; F53L; K57E; Q56P; and K57N.

In some embodiments, the present disclosure provides a method for re-sensitizing a tumor that is resistant to a therapeutic agent targeting a RAS pathway signal transducer, the method comprising administering a SHP2 inhibitor. In particular embodiments, the therapeutic agent is a MAPK inhibitor (e.g., MEK inhibitor or an ERK inhibitor). Suitable MAPK inhibitors are known in the art, are disclosed herein, and include, without limitation: MEK inhibitors, one or more MAPK inhibitor described in Cancers (Basel). 2015 September; 7(3): 1758-1784, incorporated herein by reference in its entirety, one or more of Trametinib, Binimetinib, Selumetinib, Cobimetinib, LErafAON (NeoPharm), ISIS 5132; Vemurafenib, Pimasertib, TAK733, RO4987655 (CH4987655); CI-1040; PD-0325901; CH5126766; MAP855; AZD6244; Refametinib (RDEA 119/BAY 86-9766); GDC-0973/XL581; AZD8330 (ARRY-424704/ARRY-704); RO5126766 (Roche, described in PLoS One. 2014 Nov. 25; 9(11), incorporated herein by reference in its entirety); and GSK1120212 (or “JTP-74057”, described in Clin Cancer Res. 2011 Mar. 1; 17(5):989-1000, incorporated herein by reference in its entirety.
In some embodiments, the present disclosure provides a method for treating cells (e.g., cancer cells) with a SHP2 inhibitor, wherein the cells have been rendered dependent on SHP2 by treatment with a therapeutic agent (e.g., a MAPK inhibitor). The therapeutic agent may be a MAPK inhibitor selected from a MEK inhibitor and an ERK inhibitor. The therapeutic agent may induce overactivation of the RAS pathway via relief of a natural RAS pathway negative feedback mechanism, wherein the overactivated RAS pathway is dependent on SHP2 signaling (e.g., for priming the reloading of GTP onto RAS). Administration of a SHP2 inhibitor in combination with the therapeutic agent (e.g., a MAPK inhibitor) may prevents such overactivation of the RAS pathway by the therapeutic agent. Such cells may, but need not comprise a RAS pathway mutation that confers cellular dependence on SHP2 (e.g., for reloading of GTP onto RAS). Treatment with a SHP2 inhibitor in combination with a MAPK inhibitor (e.g., a MEK or ERK inhibitor) may prevent MAPK inhibitor-induced feedback activation of the RAS pathway.
The present invention also provides methods for determining whether a subject has tumor that will be responsive to SHP2 inhibition. The method may comprise determining whether the tumor is classified as an NF1LOF subtype and administering to the subject an inhibitor of SHP2 if the tumor is classified as an NF1LOF subtype. In some embodiments, the determining may comprise empirical determining, e.g., via experimentation. Such methods for determining a subtype of a tumor are known in the art and may include genotyping, measuring NF1 protein levels, determining the size of NF1 (e.g., via any suitable method such as western blot, mass spectrometry, size exclusion chromatography), or measuring by a functional assay such as, a RAS-GTP accumulation assay.

Effect of SHP2 Allosteric Inhibitors on Cancer Cells Containing Ras Pathway Mutations and Dependent Upon Reloading of GTP onto KRAS
The effect of SHP2 allosteric inhibitors, Compound A or Compound B on RAS pathway activation and tumor cell growth in vitro, and in vivo, was evaluated in cancer cell lines with Ras pathway mutations, including distinct mutations in KRAS, NF1, and BRAF that confer cellular dependence on reloading of GTP onto RAS.
To evaluate cell viability in 3D culture, cells in logarithmic growth phase were plated in growth medium containing 0.65% methylcellulose at an optimum seeding density. Cells were incubated overnight prior to treatment with different concentrations of the test article. Cells were cultured for an additional seven days and cell viability assessed using the CellTiterGlo™ (CTG) reagent, according to the manufacturer's instructions. In some instances, cells were grown in 3D culture as spheroids. Briefly, 2500 cells/well were seeded in round bottom ultra-low attachment 96-well plates (Corning) in growth media supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin, and allowed to form spheroids for 72 hours at 37° C. in 5% CO2. Spheroid formation was confirmed visually, and spheroids were treated in duplicate with serial 3-fold dilutions of Compound B in complete growth media (final DMSO concentration=0.1%). Following drug exposure for five days, cell viability in spheroids was determined using the CellTiter-Glo assay kit. H1838 cells were seeded at 5×103 cells per well of a 12-well plate. After one day in culture, cells were treated with the test article, which was then replenished every three days. Cells were maintained in culture for 10 days until the control wells reached confluency at which time the cells were fixed and stained with crystal violet.
To determine the potency of test articles to inhibit phosphorylation of extracellular signal-related kinase 1 and 2 (ERK1/2) at Thr202/Tyr204 (p-ERK), respective cell lines were cultured under standard 2D culture conditions. Cells were plated at ˜20×103 cells per well and following overnight incubation were washed with serum-free media. Cells were then incubated for one hour with increasing concentrations of the test article in serum-free media containing 0.2% BSA prior to termination of the assay and measurement of pERK levels in cellular lysates by AlphaLisa SureFire Ultra kit conducted according to the manufacturer's instructions.
To determine the effects of small molecules on levels of activated RAS-GTPase, cell lines of interest were cultured under standard 2D culture conditions. Cells were seeded and following overnight incubation incubated at 37° C. with vehicle (DMSO) or test article(s). After an appropriate incubation period, cells were washed and cell lysis buffer added to prepare a cell lysate. The levels of Ras-GTP in the lysates were determined using affinity purification of a Raf-RBD (Ras binding domain of Raf)/GTP-Ras complex. In one approach, the Pierce Active Ras Pulldown and Detection Kit was used. Briefly, clarified lysates (500 μg total protein, quantified by BCA) were mixed with glutathione resin, which had been preincubated with GST-Raf-RBD. The mixture was vortexed and incubated at 4° C. for 1 hour with gentle rocking. The resin was washed three times with lysis buffer and bound Ras-GTP eluted by addition of 2× reducing sample buffer. Eluted proteins were separated by SDS-PAGE using a 4-15% Tris-glycine gel (BioRad). Proteins were transferred to a nitrocellulose membrane for western blot using an anti-Ras antibody (Thermofisher, 1:200) and a Licor IRDye-800 anti-mouse secondary antibody (1:20,000). The Licor Odyssey CLx was used for visualization.
The effects of a SHP2 inhibitor on tumor cell growth in vivo were evaluated in the NSCLC H358 KRasG12C xenograft model using female CB.17 SCID (8-12 weeks old) or Balb/c (6-8 weeks old). Mice were implanted with H358 tumor cells in 50% Matrigel (1×107 and 5×106 for SCID and Balb/c mice, respectively) subcutaneously in the flank. Once tumors reached an average size of ˜200 mm3 mice were randomized to treatment groups and administration of test article or vehicle (50 mM acetate buffer, pH 4.6 containing 10% captisol, unless otherwise indicated) initiated. Body weight and tumor volume (using calipers) was measured biweekly until study endpoint. Compound A or Compound B were administered by oral gavage daily. The positive control, paclitaxel (30 mg/kg iv) in 5% ethanol, 5% cremophor EL, in 5% dextrose in deionized water was administered once every five days. Trametinib (1 mg/kg PO in 0.5% Methylcellulose+0.5% Tween 80) was administered by oral gavage daily. The study endpoint was defined as a mean tumor volume of 2000 mm3 in the control group or 22 days, whichever came first. Mean tumor volume data are reported for all animals that remained on study.
Similar methods were used to evaluate efficacy of test articles in the pancreatic MiaPaca-2 KRasG12C xenograft model. Balb/c nude mice (6-8 weeks old) were implanted with 1.35×109 MiaPaca-2 tumor cells in 50% Matrigel subcutaneously in the flank. Once tumors reached an average size of ˜100-200 mm3 mice were randomized to treatment groups. Administration of test articles and study design are as described above for H358 xenograft model.
Across a small panel of KRAS mutant cell lines, presence of a KRASG12C mutation enriched for sensitivity to 3D growth inhibition (defined as a CTG IC50<10 μM) by a SHP2 inhibitor (Compound A) (Table 3; Ref #1 Crown Bio Project #E3105-U1609).
Consistent with and extending these observations, Compound B, was a potent inhibitor of growth (CTG IC50 range 0.4 to 7.87 μM) in 9/10 KRASG12C lines, 2/2 KRASG12A lines, 2/5 KRASG12D lines, and also two KRASG12V lines, H441 (
One such protein involved in the RAS Pathway that might confer sensitivity to SHP2 signaling by its absence or reduced function is NF1 NF1 is a RAS-GAP protein that facilitates the hydrolysis of RAS-GTP into its inactive RAS-GTP form, thereby inactivating RAS. NF1 is a tumor suppressor, and loss of function mutations in this gene result RAS-GTP accumulation and downstream signaling leading to cell growth in various human cancers (Nissan, Krauthammer, Redig). Therefore, we tested whether SHP2 inhibition might effectively prevent RAS pathway signaling and cell growth in NF1LOF models.
Similar to the observations in the KRASG12C line, Compound A also inhibited Ras-GTP and potently inhibited p-ERK and cell growth (crystal violet stain) in H1838 NF1LOF NSCLC cells in vitro (
Taken together, these results suggest that a SHP2 inhibitor can attenuate RAS-MAPK signaling in KRASG12C mutant cell lines and NF1 loss of function cell lines, while differential sensitivity to growth inhibition may be observed, which likely reflects the intrinsic variation in dependence of each cell line on signaling via the Ras pathway.
The effect of a SHP2 inhibitor on KRASG12C tumor cell growth in vivo was evaluated in the NSCLC H358 and pancreatic MiaPaca-2 xenograft models. Oral administration of Compound A or Compound B, respectively, produced a dose-dependent decrease in tumor volume in vivo in the H358 xenograft model (
Similarly, Compound A was also a potent inhibitor of p-ERK (
Another protein that is involved in signaling via the RAS Pathway is the serine/threonine kinase BRAF, and mutations in BRAF are commonly present in human cancer, and such mutations are oncogenic because of their resultant hyperactivation of pERK signaling. Three classes of oncogenic BRAF mutations have been reported. Class I mutations occur at V600 and result in constitutively active BRAF monomers that are active regardless of their RAS-GTP state (Poulikakos, 2011). Class II mutations are dependent on dimerization, but also are active regardless of their RAS-GTP state (Yao, 2015). Class III mutations of BRAF are both RAF dimer and RAS-GTP dependent (Yao, 2017). Accordingly, we posited that Class I and Class I mutations might be refractory to SHP2 inhibition because they singal independent of GTP, whereas, in contrast Class III mutations might be dependent on SHP2 signaling to promote adequate GTP loading, and cells containing these mutations might, therefore, be sensitive to SHP2 inhibition.
We screened a representative panel of cell lines bearing oncogenic BRAF mutations in these three classes for sensitivity to SHP2 inhibition.
First, we confirmed that Class I BRAF mutations were refractory to SHP2 inhibition. Consistent with the mechanistic framework, we observed that Compound B failed to suppress proliferation and RAS-GTP and pERK levels in A375 cells (
However, in three cell lines carrying Class III BRAF mutations, NCI-H1666 (BRAFG466V/+), NCI-H508 (BRAFG596R/+), and Cal-12T (BRAFG466V/+), treatment with Compound B led to concordant suppression of both pERK levels (
To more fully define the cellular effects of Compound B, we examined biomarkers of cell cycle and apoptosis. Activated Caspase 3/7 Assay in Spheroids. NCI-H358 cells (Lung, KRASG12C) were grown into spheroids by seeding 5,000 cells/well in round bottom ultra-low attachment 96-well plates (Corning) in RPMI media (Gibco) supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin. Immediately after seeding, cells were spun down at 1000 RPM for 5 minutes, and incubated at 37° C. in 5% CO2 for five days to allow for spheroid formation. Spheroid formation was confirmed visually. Spheroids were treated in triplicate with Compound B, staurosporine (Sigma), or DMSO (Sigma) (0.1% final), diluted in RPMI media supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin, and incubated at 37° C. in 5% CO2 for 20 hours. Caspase 3/7 activity was measured using the Caspase-Glo 3/7 Assay System (Promega), following the manufacturer's instructions. After addition of Caspase-Glo reagent, the well contents were pipetted several times and incubated at room temperature in the dark for 45 minutes to allow thorough cell lysis. 50 μL of the lysate/reaction was transferred to an opaque white 96-well ½ area plates (Perkin Elmer). Luminescence was read in an EnVision Multilabel Plate Reader (Perkin Elmer). Assay data was plotted using Prism 7 (GraphPad) software.
In NCI-H358 cells (Lung, KRASG12C), treatment of spheroid cultures with Compound B led to robust caspase 3/7 activation, indicating a pro-apoptotic effect (
To extend our studies into additional clinically-relevant in vivo models, we evaluated the response to Compound B mediated SHP2 inhibition in patient-derived xenograft (PDX) models. Two PDX models of BRAF mutant NSCLC, LUN023 and LUN037, were tested. LUN023 carries the previously described class 3 mutation BRAFD594N {Yao, 2017 #2432}, while LUN037 carries BRAFN581D, a known class 3 residue and established RASopathy substitution {Niihori, 2006 #2538}. As predicted for this class of semi-autonomous driver of RAS/MAPK signaling, we observed dose-dependent tumor growth inhibition upon repeated daily oral dosing of Compound B in both models (
The observation that a SHP2 inhibitor can inhibit some, but not all, KRAS mutant cells is likely a function of the nucleotide cycling features of a particular KRAS mutation and its corresponding dependence on signaling inputs to maintain high levels of the active, GTP-bound state. Indeed Patricelli and coworkers have demonstrated that KRASG12C is not a constitutively and fully active protein but rather the nucleotide state of KRASG12C is in a state of dynamic flux that can be modulated by upstream signaling factors (Patricelli et al., 2016). Similarly, in cells which have lost function of the GTPase activating protein (GAP), e.g. NF1LOF there is a shift towards the active, GTP-bound state of RAS which drives signaling to RAS effectors and growth addiction. In these cells, the wild type RAS undergoes nucleotide cycling which, as for KRASG12C makes it sensitive to upstream signaling inputs to maintain a highly active state. In addition, cells which have acquired a Class 3 mutation in BRAF drive high pERK signaling in a manner that remains dependent on RAS-GTP, and therefore on upstream signaling factors. The sensitivity of KRASG12C; NF1LOF; and BRAF Class 3 cell lines to a SHP2 allosteric inhibitor reflects modulation of these upstream factors, and hence the nucleotide state of mutant/WT RAS, by the inhibitor.
Objective: The effect of SHP2 allosteric inhibitors, Compound A or Compound B, on feedback-driven RAS pathway activation resulting from MEK inhibition was evaluated in various cancer cell lines comprising distinct mutations in KRAS and other mutations that modulate nucleotide cycling of RAS, such as NF1LOF.
To determine the effects of test article(s) on levels of phosphorylated RTKs, MDA-MB231 cells were seeded in 6-well plates and incubated overnight in full growth medium. Cells were treated for 24 hours with selumetinib (5 μM) or Compound A (1 and 5 μM) or left untreated (DMSO control). Lysates were generated using the lysis buffer provided with the kit (Phospho-RTK Array; R&D systems) with inclusion of a protease inhibitor cocktail. To control for protein concentration, total protein levels were quantified using BCA reagent kit. The levels of phospho-RTK were determined according to the manufacturer's instructions.
To determine the effects of small molecules on levels of activated RAS-GTPase, cell lines of interest were cultured under standard 2D culture conditions. Cells were seeded and following overnight incubation incubated at 37° C. with vehicle (DMSO) or test article(s). After an appropriate incubation period, cells were washed and cell lysis buffer added to prepare a cell lysate. The levels of Ras-GTP in the lysates were determined using affinity purification of a Raf-RBD (Ras binding domain of Raf)/GTP-Ras complex. In one approach, the Pierce Active Ras Pulldown and Detection Kit was used. Briefly, clarified lysates (500 μg total protein, quantified by BCA) were mixed with glutathione resin which had been preincubated with GST-Raf-RBD. The mixture was vortexed and incubated at 4° C. for 1 hour with gentle rocking. The resin was washed three times with lysis buffer and bound Ras-GTP eluted by addition of 2× reducing sample buffer. Eluted proteins were separated by SDS-PAGE using a 4-15% Tris-glycine gel (BioRad). Proteins were transferred to a nitrocellulose membrane for western blot using an anti-Ras antibody (Thermofisher, 1:200) and a Licor IRDye-800 anti-mouse secondary antibody (1:20,000). The Licor Odyssey CLx was used for visualization.
The observation that a SHP2 inhibitor can prevent the feedback reactivation of RTKs, as read out by their phosphorylation status (
Objective: To determine whether inhibition of SHP2 with an allosteric inhibitor prevents tyrosine phosphorylation of the C-terminal tail (Tyr-542 and Tyr-580) of SHP2.
Tyrosine phosphorylation of the C-terminal tail (Tyr-542 and Tyr-580) of SHP2 has been proposed to have both regulatory and functional consequences. Early work proposed that SHP2 acts as a scaffolding protein to link PDGFRP to Ras by interactions with Grb2-SOS (Bennett, 1994) via tyrosine phosphorylation after growth factor stimulation. However, it remains controversial whether Grb2 binds to pY542 or pY580 in a cellular context, and whether this interaction is the main functional consequence of Y542/580 phosphorylation. Lu et. al (2001) used phosphotyrosine mimics at these sites to show that phosphorylation increases SHP2 PTPase activity, presumably through intramolecular interactions with the SH2 domains. This suggests that phosphorylation of these residues may contribute significantly towards enzyme activity rather than scaffolding. Subsequent work identified a growth factor specificity for tyrosine phosphorylation in murine fibroblasts (PDGF, FGF, but not EGF) and also concluded that Y580 phosphorylation occurs after, and is dependent on, phosphorylation of Y542 (Araki et al., 2003). This observation led the authors to hypothesize that in a “closed state” Y580 is inaccessible to phosphorylation until a conformational change evoked by phosphorylation of Y542 occurs. They also proposed that p-Y542 is the main Grb2 binding site in fibroblasts. A comprehensive study using FRET corroborated that p-Y542/580 interact with the SHP2 SH2 domains, and that Y580 phosphorylation is dependent on phosphorylation of Y542 (Sun et al, 2013). This study identified Y580 as the likely major binding site for Grb2 in MEFs. Based on these observations, SHP2 pY542 has been used as a biomarker to identify RTK-driven resistance to BRAF inhibitors (Prahallad, 2015), since phosphorylation of this residue occurs in response to RTK signaling.
Cells (MEFs, HEK 293E, H358) were plated in 6-well plates at a density of 750,000 cells/well in low serum (0.1% FBS) media and allowed to grow overnight. Cells were incubated with either DMSO (0.05%), or Compound B (5 μM) for 1 hour. Cells were stimulated with 50 ng/mL of EGF or PDGF for 5 minutes, washed with cold PBS, and 150 μL of lysis buffer (Thermo #1862301) with Halt Protease/Phosphatase inhibitor (Thermo #78440) was added. Cells were scraped, transferred to a cold Eppendorf tube and vortexed for 10 seconds. Lysates were spun at 4 C for 15 min at 13,000 rpm and transferred to a new tube. Lysate protein concentration was assessed using the BCA assay. Lysates (30 μg/lane) were run on a 4-15% Tris glycine gel and transferred to a nitrocellulose membrane using the iBlot2. Western blots were performed using phospho-SHP2 antibodies from Cell Signaling Technologies; pY542 (#3751) and pY580 (#3703) were both used at 1:1000 dilution in 5% BSA in TBS. Membranes were incubated with primary antibody overnight with gentle shaking at 4 C. Beta actin antibody (Cell Signaling Technologies #8457, 1:2000) was used as a loading control. The secondary antibody (Licor IRDye 800 CW anti-rabbit) was used at a 1:20000 dilution in 5% BSA in TBS for 1 hour shaking at room temperature. Blots were visualized using the Licor Odyssey Clx Imager.
These experiments show an increase in phosphorylation of Tyr-542 and Tyr-580 in response to growth factors. In agreement with the literature, this phosphorylation is stimulated by PDGF in MEFs, but not EGF. Conversely, in HEK293 and H358 cells, where MAPK signaling is predominantly EGF stimulated (data not shown), we observe phosphorylation with EGF, but not PDGF. These results suggest that the growth factor specificity of SHP2 Y542/Y580 phosphorylation is cell line dependent. Treatment of these cells with Compound B, an allosteric inhibitor which stabilizes the auto-inhibited, closed conformation of SHP2, decreases the overall phosphorylation levels of Y580, but not Y542. This observation agrees with the hypothesis proposed by Araki et al. (2003); Y580 is occluded from phosphorylation in a “closed state”. We postulate that Compound B stabilizes this “closed state”, preventing phosphorylation at this site. It is currently unclear whether the cellular functional consequences of Compound B inhibition of phosphorylation of Y580 are linked to attenuation of Grb2 binding or to a reduction in SHP2 PTPase activity. However, taken collectively, the present observations suggest that inhibition of phosphorylation of Y580 may serve as a marker of Compound B, or other allosteric SHP2 inhibitor, target engagement in a cell. Furthermore, the present observations suggest that pY580 levels/dependence may be predictive of sensitivity to Compound B or another SHP2 inhibitor.
Objective: To demonstrate the inhibition of SHP2 activity with Compounds A, B, and C.
Without wishing to be bound by theory, SHP is allosterically activated through binding of bis-tyrosyl-phosphorylated peptides to its Src Homology 2 (SH2) domains. The latter activation step leads to the release of the auto-inhibitory interface of SHP2, which in turn renders the SHP2 protein tyrosine phosphatase (PTP) active and available for substrate recognition and reaction catalysis. The catalytic activity of SHP2 was monitored using the surrogate substrate DiFMUP in a prompt fluorescence assay format.
The phosphatase reactions were performed at room temperature in 96-well black polystyrene plate, flat bottom, non-binding surface (Corning, Cat #3650) using a final reaction volume of 100 μL and the following assay buffer conditions: 50 mM HEPES, pH 7.2, 100 mM NaCl, 0.5 mM EDTA, 0.05% P-20, 1 mM DTT.
The inhibition of SHP2 by Compound A, Compound B, and Compound C was monitored using an assay in which 0.2 nM of SHP2 was incubated with 0.5 μM of Activating Peptide 1 (sequence: H2N-LN(pY)IDLDLV(dPEG8)LST(pY)ASINFQK-amide) (SEQ ID NO: 4) or Activating Peptide 2 (sequence: H2N-LN(pY)AQLWHA(dPEG8)LTI(pY)ATIRRF-amide) (SEQ ID NO: 5). After 30-60 minutes incubation at 25° C., the surrogate substrate DiFMUP (Invitrogen, Cat #D6567) was added to the reaction and activity was determined by a kinetic read using a microplate reader (Envision, Perkin-Elmer or Spectramax M5, Molecular Devices). The excitation and emission wavelengths were 340 nm and 450 nm, respectively. Initial rates were determined from a linear fit of the data, and the inhibitor dose response curves were analyzed using normalized IC50 regression curve fitting with control based normalization.
Using the above-protocol, SHP2 inhibition by Compound A, Compound B, and Compound C is shown in Table 4.
In light of our findings that multiple classes of RAS/MAPK pathway oncoproteins that remain dependent upon RAS-GTP loading can be targeted via SHP2 inhibition, we asked whether SHP2-dependent modulation of RAS-GTP was due to disruption of core RAS-regulatory processes.
N-terminally HA-tagged SOS-WT and SOS-F constructs were synthesized (Atum) and subcloned into the pcDNA5/FRT/TO vector (ThermoFisher) using the following primers: SOS1-HA-F or 5′-ACAGGTAAGCTTATGTACCCATACGATGTTCCAGATTAC-3′ (SEQ ID NO: 1), SOS1-HA-REV 5′-AGACTAGCGGCCGCTCAGGAAGAATGGGCATTCTCCAA-3′ (SEQ ID NO: 2), and SOS-F-HA-REV 5′-GATCGAGCGGCCGCTCAGGAGAGCACACACTTGCAG-3′ (SEQ ID NO: 3). SOS-WT and SOS-F plasmids were co-transfected with the pOG44 Flp-recombinase expression vector (ThermoFisher) into the HEK Flp-In T-Rex 293 cell line according to the manufacturer's protocol. Transfected cells were selected in drug media (200 μg/mL hygromycin B, 15 μg/mL blastidicin) and expression of SOS constructs was verified by western blot (SOS-1: Cell Signaling Technologies #5890; HA: Sigma 11867423001).
pERK Analysis of HEK-293 SOS-WT and SOS-F
30,000 HEK-293 cells per well were plated in 96-well plates in Biotin-free RPMI (Hyclone) supplemented with 0.1% fetal bovine serum, 0.02% bovine serum albumin and 1% penicillin/streptomycin. Expression of SOS1 constructs was induced by the addition 0.1 μg/mL doxycycline (Sigma) for 24 hours. Cells were treated with serial 3-fold dilutions of Compound B diluted in biotin-free media supplemented with 0.02% bovine serum albumin and 1% penicillin/streptomycin (final DMSO concentration equivalent to 0.1%) for one hour. For the final 5 minutes of drug treatment, cells were stimulated with 50 ng/mL EGF (Sigma), lysed and subjected to ERK1/2 phosphorylation analysis as described above.
First, we mined data from the recently published Project DRIVE (McDonald, 2017), in which thousands of genes were systematically depleted across hundreds of cell lines to study genetic-dependencies of molecularly-defined cancer cell lines. One way to identify functional modules from high-throughput genetic knockdown experiments is to examine the phenotypic correlation of all possible gene pairs across the full dataset, as knockdown of members of a common functional module tends to yield similar patterns of response over many independent experiments. Taking a hypothesis-driven approach, we pulled data for 23 genes involved in RTK or RAS Pathway signaling and calculated a correlation matrix (
To test this hypothesis, we first asked whether a dominant, constitutively active mutant form of SOS1 could render cells insensitive to Compound B-mediated suppression of pERK signaling. Indeed, in HEK293 cells, inducible expression of SOS-F, a SOS1 mutant with its C-terminus fused to the HRAS farnesylation motif that targets the protein constitutively to the plasma membrane (Aronheim, 1994), rendered pERK signaling insensitive to EGF stimulation and SHP2 inhibition (
We have discovered a novel allosteric SHP2 inhibitor, Compound B, and used it and other SHP2 inhibitors to search for molecular markers of SHP2-dependence in tumors bearing mutations in the RAS Pathway. The identification of KRASG12C NF1LOF, and BRAFClass III mutations that confer sensitivity to SHP2 inhibition in tumor cells establishes SHP2 inhibition as a novel and promising therapeutic strategy against tumors bearing these oncogenic drivers, for which current treatments are largely ineffective in the clinic.
In NSCLC, these semi-autonomous driver mutations are observed frequently: KRASG12C, NF1LOF and BRAFClass III mutations collectively represent about 3% of all cases in the US annually. Importantly, patients whose cancers carry these mutations are dramatically underserved, as no targeted therapies have been approved for these molecular subtypes. The data presented here raise the exciting possibility that a SHP2 inhibitor may make these mutations clinically actionable and improve the outlook for patients.
Our data show that SHP2 is not just a convergent signaling node downstream of multiple RTKs, but instead is an essential regulator of oncogenic RAS activation. Importantly, many tumors remain sensitive to SHP2 inhibition even when the oncogenic ‘driver’ mutation is apparently downstream of SHP2 in the canonical pathway. The association of SHP2 with SOS1 and GRB2 provide a mechanistic context for SHP2's precise role in the regulation of RAS-GTP levels, and presents clear hypotheses around the impact of allosteric inhibitors on this functional module.
The preserved dependence of KRASG12C, NF1LOF, and BRAFClass III mutations on SHP2-mediated upstream signals suggests that certain mutant forms of RAS pathway oncogenic drivers amplify, rather than bypass, the homeostatic mechanisms regulating RAS-GTP and pathway output. This contrasts with a common assumption that RAS oncogenes are locked in the “on” GTP-bound state constitutively to drive signaling and cancer, and is consistent with a framework in which certain oncogenic mutations are semi-autonomous, rather than fully-autonomous, drivers of cancer. More broadly, our study highlights the power of developing selective and potent pharmacologic probes to uncover occult features of oncogenic RAS signaling and unanticipated therapeutic opportunities.
Effect of SHP2 Allosteric Inhibitor (Compound B) on In Vitro Tumor Cell Growth Alone and in Combination with MEK Inhibitor Trametinib
Objective: To evaluate the efficacy of the SHP2 allosteric inhibitor Compound B alone and in combination with trametinib, in vitro, in tumor cells from human non-small cell lung cancer cell lines CALU-1 and NCI-H358.
Cells were grown in 3D culture as spheroids. Briefly, 2500 cells/well were seeded in round bottom ultra-low attachment 96-well plates (Corning) in growth media supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin, and allowed to form spheroids for 72 hours at 37° C. in 5% CO2. Spheroid formation was confirmed visually, and spheroids were treated in duplicate with serial 3-fold dilutions of Compound B in complete growth media (final DMSO concentration=0.1%). Following drug exposure for five days, cell viability in spheroids was determined using the CellTiter-Glo assay kit (Promega)
As shown in
Effect of SHP2 Allosteric Inhibitor (Compound B) on In Vivo Tumor Cell Growth Alone and in Combination with MEK Inhibitor Trametinib
Objective: To evaluate the efficacy of the SHP2 allosteric inhibitor Compound B alone and in combination with trametinib, following oral administration, in the human non-small cell lung cancer NCI-H358 xenograft model in nude mice.
The effects of a SHP2 inhibitor on tumor cell growth in vivo were evaluated in the NSCLC H358 xenograft model using female athymic nude mice (6-8 weeks old). Mice were implanted with H358 tumor cells in 50% Matrigel (1×107 cells/animal) subcutaneously in the flank. Once tumors reached an average size of 200 mm3 mice were randomized to treatment groups and administration of test article or vehicle (50 mM acetate buffer, pH 4.6 containing 10% captisol, unless otherwise indicated) initiated. Trametinib was formulated in a solution of 0.5% Methylcellulose+0.5% Tween 80. Body weight and tumor volume (using calipers) was measured every other day until study endpoints. Compounds were administered by oral gavage according to the schedule set forth in Table 5:
The study endpoints are also shown in Table 5. Mean tumor volume data are reported for all animals that remained on study.
The combination of trametinib at 1 mg/kg and Compound B at 10 mg/kg resulted in a mean tumor regression of 36%, and the same dose of trametinib in combination with 30 mg/kg Compound B resulted in a mean tumor regression of 71%, **p=0.001, ***p<0.0001, respectively, assessed by an ordinary one way ANOVA of tumor volumes along with multiple comparisons via a post-hoc Tukey's test in Graphpad Prism software. Three out of ten animals who received Compound B at 30 mg/kg and trametinib at 1 mg/kg achieved a complete regression of tumor which persisted at day 30.
Compound B exhibits statistically significant, biologically significant and dose-dependent efficacy in the NCI-H358 non-small cell lung cancer xenograft model following oral administration at 10 mg/kg daily and 30 mg/kg daily. Trametinib also exhibited efficacy in this model at 1 mg/kg, a dose level previously predicted to be clinically relevant. Importantly, both doses of Compound B in combination with this dose of trametinib were tolerated and caused significant tumor regressions, some of which were complete regression.
Effect of SHP2 Allosteric Inhibitor (Compound C) on In Vivo Tumor Cell Growth Alone and in Combination with MEK Inhibitor Trametinib
Objective: To evaluate the efficacy of the SHP2 allosteric inhibitor Compound C alone and in combination with Trametinib (MEK Inhibitor), Cobimetinib (MEK Inhibitor), Ulixertinib (ERK Inhibitor), and Abemaciclib (CDK4/6 Inhibitor) following oral administration, in a human non-small cell lung cancer NCI-H358 xenograft model (Trametinib, Cobimetinib, Ulixertinib) or in a human pancreatic carcinoma MIA-Pa-Ca-2 xenograft model (Abemaciclib) in nude mice.
The effects on tumor cell growth in vivo of another SHP2 inhibitor (Compound C) as a monotherapy or as a combination therapy with various Ras pathway inhibitors were evaluated in the NSCLC H358 KRasG12C and MIA-Pa-Ca-2 xenograft models as described above in Example 1, except that the test article and vehicle formulation was (2% HPMC E-50, 0.5% Tween 80 in 50 mM Sodium Citrate Buffer, pH 4.0)+/− the inhibitor compound(s). As before, body weight and tumor volume (using calipers) was measured biweekly until study endpoint. Test compounds or vehicle control were administered by oral gavage daily. The study endpoint was defined as a mean tumor volume of 2000 mm3 in the control group or 22 days post-dosing, whichever came first. Mean tumor volume data are reported for all animals that remained on study.
The combination of Trametinib at 1 mg/kg and Compound C at 10 mg/kg resulted in a significant increase in tumor regression (***p<0.0005), assessed by an ordinary one way ANOVA of tumor volumes along with multiple comparisons via a post-hoc Tukey's test in Graphpad Prism software (
Similarly, each of the combinations of Cobimetinib at 2.5 mg/kg with Compound C at 10 mg/kg (
All regimens were well tolerated for the duration of the study as evaluated by body weight (
Like Compounds A and B, Compound C exhibits statistically significant, biologically significant, and dose-dependent efficacy in the NCI-H358 non-small cell lung cancer and in the MIA-Pa-Ca-2 xenograft models following oral administration at 10 mg/kg daily and 30 mg/kg daily. Trametinib also exhibited efficacy in this model at 1 mg/kg, a dose level previously predicted to be clinically relevant, as did Cobimetinib, Ulixertinib, and Abemaciclib at clinically relevant doses of 2.5, 100, and 50 mg/kg, respectively.
Importantly, in all cases, doses of the Compound C SHP2 inhibitor in combination with the dose of the other Ras pathway inhibitors were tolerated and caused significant tumor regressions, some of which were complete regression.
