Description:
THERAPEUTIC COMBINATION OF KRAS G12C INHIBITOR AND TEAD INHIBITOR

The present disclosure relates to a therapeutic combination of at least one KRAS G12C inhibitor and at least one specific TEAD inhibitor.

The therapeutic combination disclosed herein is particularly advantageous in the treatment of KRAS G12C-mediated cancers, and more particularly in the treatment of lung, pancreatic or colorectal cancer.

RAS proteins, a family of small GTPases that integrate and transmit signals from upstream growth factor receptors, comprise the most frequently mutated protein family in human cancer and high frequency of RAS mutations are found with the top three causes of cancer deaths: lung, colorectal, and pancreatic cancer. RAS proteins function as a molecular switch. In conditions of normal signaling, ligand stimulation results in activation of the guanine nucleotide exchange factor son of sevenless (SOS) and facilitates exchange of the inactive guanosine diphosphate (GDP)-bound state of RAS to an active guanosine triphosphate (GTP)-bound state. This switch between inactive and active states enables RAS to adopt a conformation that interacts with the RAS-binding domain (RBD) of its downstream effectors and facilitates the recruitment of rapidly accelerated fibrosarcoma (RAF) family members (ARAF, BRAF, CRAF) from the cytosol to the plasma membrane which eventually leads to the activation of the MAPK signaling cascade. Active MAPK signaling further results in the activation of gene transcription programs required for cell proliferation. Under normal conditions, the activation of the RAS-RAF-MAPK signaling cascade is transient and is turned off via the action of RAS-GTPase activating (GAP) proteins. These proteins activate GTPase enzymes found within RAS, which hydrolyze GTP to GDP and therefore switch RAS off. Mutations in RAS proteins may lead to conformational changes so that the RAS-GAP protein cannot activate the inherent GTPase enzyme anymore. As a result, the GTP molecules are not hydrolysed and instead they maintain RAS continuously in its active state, thus causing pro tumorigenic effects by amplifying signaling in the MAPK pathway (reviewed in Hymowitz and Malek, CHS Perspectives 2018:8 (1 1 )).

Recently, small molecules specifically targeting the KRAS G12C oncogenic mutant protein have advanced in clinical trials (reviewed in Goebel et al, RSC Medicinal Chem:7, 2020). The KRAS G12C refers to a mutant form of the mammalian KRAS protein that contains an amino acid substitution of a cysteine for a glycine at amino acid position 12. The assignment of amino acid codon and residue positions for human KRAS is based on the amino acid sequence identified by UniProtKB/Swiss-Prot P011 16: Variant p.Gly12Cys.

On the other hand, the transcriptional enhanced associate domain (TEAD) family of transcription factors TEAD1 -TEAD4 are the most downstream effectors of the HIPPO- YAP1 signaling cascade, an evolutionary conserved signaling pathway whose deregulation is described for different cancer types (reviewed in Nguyen and Yi, Trends Cancer. 2019, 5:283-296). The core of the HIPPO pathway in mammals consists of a cascade of kinases including MST1/2 and LATS1/2, their associated adaptor proteins SAV1 and MOB1 , as well as upstream regulators, such as NF2, SCRIBBLE, CRUMBS, and multiple G protein- coupled receptors. In the healthy adult human organism, the HIPPO pathway kinases are mainly found in their “on” state in which they actively phosphorylate YAP1 and TAZ (WWTR1 gene) proteins. Phosphorylated YAP1 and TAZ then remain inactive through sequestration in the cytoplasm and/or degradation by the proteasomal machinery. In many tumors, HIPPO signaling is found in the “off” state, in which case cytosolic YAP1 and TAZ proteins are not anymore phosphorylated and hence free to translocate to the cell nucleus, where they associate with TEAD transcription factors. The YAP1 -TEAD or TAZ-TEAD couples then bind to DNA and induce the expression of genes that promote cell proliferation and cell survival (reviewed in Totaro et al., Nature Cell Bio. 2018, 20:888-899).

Small molecule allosteric ligands binding to the central lipid pocket of TEAD proteins are capable of inhibiting aberrant YAP1 -TEAD or TAZ-TEAD activation and several such allosteric TEAD inhibitors have been described in the literature with K-975 being one of the publicly known examples (Kaneda etal., Am J Cancer Res. 2020, 10:4399-4415). Allosteric TEAD inhibitors inhibit the growth of tumor cells in vitro and in vivo and are active in tumor types that depend on TEAD activity and where activation of TEAD (YAP1 -TEAD or TAZ- TEAD) is the main driver of tumor growth. This is for example the case in tumor indications with dysfunctional HIPPO signaling, which is for example the case in malignant mesothelioma tumors with HIPPO kinase or NF2 inactivation (Kaneda et al.). In tumors, in which TEAD is not the driver of tumor cell growth, TEAD inhibitors have no effect and can be added to in vitro and in vivo models without any impact on tumor cell proliferation and survival.

As every signaling pathway, the HIPPO-YAP1 / TAZ -TEAD signaling cascade does not exist in isolation but cross-talks with other signaling pathways. For example, the crosstalk between this pathway and the MAPK pathway has recently been reported (Pham et al., Cancer Discovery 2020, 11 :778-793). The MAPK pathway is tightly regulated by RAS proteins.

The present disclosure provides the unexpected finding that the combination of a specific TEAD inhibitor with a KRAS G12C inhibitor is particularly effective in the treatment of tumors harboring KRAS G12C mutations, and thus for its use in the treatment of KRAS G12C-associated cancers, including lung adenocarcinoma, pancreatic ductal adenocarcinoma, rectum adenocarcinoma, colon adenocarcinoma, bile duct carcinoma, chronic myelomonocytic leukemia (CMML), rhabdomyosarcoma, endometrial cancer, bladder cancer, and ovarian cancer (Li et al., Nat Rev Cancer, 2018 Dec; 18(12):767:777).

Thus, according to one of its aspects, the present disclosure provides a therapeutic combination comprising at least one KRAS G12C inhibitor and at least one specific TEAD inhibitor selected from the group consisting of molecules of formula (III), indole compounds of formula (IV), indane compounds of formula (V) as detailed hereafter and the pharmaceutically acceptable salts thereof.

Surprisingly, as shown in the tests of the examples set out below in different KRAS tumor models with KRAS G12C mutations, the inventors have discovered that the addition of said TEAD inhibitor in combination with a KRAS G12C inhibitor makes it possible to significantly improve the inhibition of the KRAS G12C mutant cell line growth, in comparison with the effect achieved with the KRAS G12C inhibitor alone.

Thus, the presence of said TEAD inhibitor makes it possible to stimulate/potentiate the inhibition effect of the KRAS G12C inhibitor.

As illustrated in the examples, the combination of said TEAD inhibitor with said KRAS G12C inhibitor surprisingly potentiates the effect of the KRAS G12C inhibitor by several orders of magnitude and up to 100 x in some cases. This significant potentiation effect for the inhibition of KRAS G12C is especially even more surprisingly, given that these specific TEAD inhibitors alone are totally inactive on tumor models with KRAS G12C mutations.

APPLICATIONS

As mentioned above, the inventors have shown that the presence of a specific TEAD inhibitor as described above, in combination with a KRAS G12C inhibitor, makes it possible to drastically enhance the efficiency of the KRAS G12C inhibitor.

Thus, the combination of a TEAD inhibitor as disclosed hereabove and a KRAS G12C inhibitor results in synergistically effect for inhibiting KRAS G12C protein. The potentiation effect of the addition of said TEAD inhibitor in combination with a KRAS G12C inhibitor advantageously allows to consider the implementation of a reduced dose of the KRAS G12C inhibitor with the same, or even an improved efficacy.

Said KRAS G12C inhibitor and said TEAD inhibitor are thus used in combination therapy. The therapeutic combination of said KRAS G12C inhibitor(s) and said TEAD inhibitor(s) is more particularly for use in treating pathologies involving KRAS G12C, in particular in treating KRAS G12C-associated diseases or disorders, especially KRAS G12C-mediated cancers.

The KRAS G12C-mediated cancers include lung adenocarcinoma, pancreatic ductal adenocarcinoma, rectum adenocarcinoma, colon adenocarcinoma, bile duct carcinoma, chronic myelomonocytic leukemia (CMML), rhabdomyosarcoma, endometrial cancer, bladder cancer, and ovarian cancer.

The combination of said KRAS G12C inhibitor and said TEAD inhibitor may advantageously be used in the treatment of non-small cell lung, small cell lung, pancreatic or colorectal cancer.

Thus, according to another aspect, hereinafter is described a therapeutic combination of KRAS G12C inhibitor(s) and specific TEAD inhibitor(s) as disclosed above for use in the treatment of KRAS G12C-mediated cancers, in particular lung adenocarcinoma, pancreatic ductal adenocarcinoma, rectum adenocarcinoma, colon adenocarcinoma, bile duct carcinoma, chronic myelomonocytic leukemia (CMML), rhabdomyosarcoma, endometrial cancer, bladder cancer, and ovarian cancer; and more particularly of non-small cell lung, small cell lung, pancreatic or colorectal cancer.

The therapeutic combination may be used in the treatment of a patient who has exhibited resistance to prior anti-cancer therapy.

The KRAS G12C inhibitor(s) and TEAD inhibitor(s) used in combination can be administered simultaneously or separately.

The administration of a therapeutic combination can thus include simultaneous administration of the two inhibitors in the same dosage form, simultaneous administration in separate dosage forms, and separate administration. The KRAS G12C inhibitor is more particularly administered in a therapeutically effective amount. A “therapeutically effective amount or dose” is an amount that is sufficient to negatively modulate or inhibit the activity of KRAS G12C, and thus to ameliorate, or in some manner reduce a symptom or stop or reverse progression of the condition involving KRAS G12C.

A therapeutically effective amount may vary depending upon the subject (e.g. the weight, age and gender of the subject), disease conditions being treated, the severity of the disease condition and the manner of administration.

The TEAD inhibitor is co-administered in combination with the KRAS G12C inhibitor in an amount sufficient to achieve the effect of potentiation of the activity of said KRAS G12C inhibitor. In particular, the TEAD inhibitor in combination therapy is not administered in a therapeutically effective amount. This means that the TEAD inhibitor alone has no effect in the therapeutic treatment, in particular for the treatment of the targeted cancer.

The terms “co-administration” or “administered in combination with” as used herein encompass administration of both KRAS G12C inhibitor(s) and TEAD inhibitor(s) to a subject so that both inhibitors and/or their metabolites are present in the subject at the same time. Co-administration includes combination and pharmaceutical composition not exclusively limited to the ones which are obtained by physical association of the constituents in a single unit dosage, but also to those which allow a separate administration, which can be simultaneous or sequential (also called “spaced out” or “spread out”) over a period of time. Simultaneous administration in separate compositions and administration in a single unit dosage are preferred.

The KRAS G12C inhibitor and TEAD inhibitor of the therapeutic combination may be administered by any method well known in the art. They may be administered by any route, including, without limitation, parenteral, oral, transdermal, and other dosage forms.

The therapeutic combination may also be administered in combination with at least one third active agent, in particular selected from known active agents in anti-cancer therapy. The therapeutic combination or pharmaceutical composition may also be used in combination with other treatments, such as radiotherapy or chemotherapy. In one embodiment, both KRAS G12C inhibitor(s) and TEAD inhibitor(s), in particular as described above, can be formulated together in the same dosage form and administered simultaneously.

The combination of KRAS G12C inhibitor(s) and TEAD inhibitor(s) may be used as medicaments, especially medicaments for the treatment of KRAS-G12C-mediated cancers. Thus, there is also described a medicament that comprise at least one KRAS G12C inhibitor and at least one specific TEAD inhibitor as disclosed hereabove.

According to another of its aspects, the present disclosure relates to a pharmaceutical composition comprising the previously described therapeutic combination, in other words comprising at least one KRAS G12C inhibitor in particular as described above and at least one TEAD inhibitor as disclosed hereabove.

In particular, the pharmaceutical composition contains a therapeutically effective dose of said KRAS G12C inhibitor and said TEAD inhibitor in an effective amount to reach a potentiation effect for inhibiting KRAS G12C protein.

In one embodiment, said pharmaceutical composition is for use in the treatment of KRAS G12C-mediated cancers as mentioned above.

The pharmaceutical composition may also contain at least one pharmaceutically acceptable excipient, diluent and/or carrier. Said excipients, diluents and/or carriers are chosen, according to the pharmaceutical form and the desired mode of administration, from the usual excipients, diluents and carriers known to those skilled in the art.

In another embodiment, the KRAS G12C inhibitor(s) and TEAD inhibitor(s) as described above can be simultaneously administered, wherein both the inhibitors are present in separate formulations.

In still another embodiment, the KRAS G12C inhibitor(s) and the TEAD inhibitor(s) can be administered separately, for example the KRAS G12C inhibitor can be administered just followed by the TEAD inhibitor, or vice versa. In some embodiments of the separate administration protocol, the KRAS G12C inhibitor and the TEAD inhibitor are administered a few minutes apart, or a few hours apart, or a few days apart.

The KRAS G12C inhibitor and the TEAD inhibitor when simultaneously administered in separate dosage forms or separately administered can be comprised in distinct pharmaceutical compositions. Said compositions may contain at least one pharmaceutically acceptable excipient, diluent and/or carrier as described above. According to another of its aspects, the present disclosure relates to a kit comprising in one or more separate packages the previously described therapeutic combination or a pharmaceutical composition comprising both KRAS G12C inhibitor(s) and TEAD inhibitor(s) as disclosed hereabove, optionally together with instructions for administration thereof and/or with a medical device for administration.

The kit is for use in co-administration of said KRAS G12C inhibitor and said TEAD inhibitor, either simultaneously or separately, especially for the treatment of KRAS G12C-mediated cancer, in particular of lung, colorectal or pancreatic cancer.

The KRAS G12C inhibitor(s) and the TEAD inhibitor(s) can be contained in a single pharmaceutical composition or in two separate pharmaceutical compositions in the kit.

According to another aspect, there is also described a method for treating a KRAS G12C- associated cancer, comprising administering the previously described therapeutic combination or pharmaceutical composition to a patient in need thereof.

There is also described a method for treating a KRAS G12C-associated cancer, comprising co-administering to a patient in need thereof a therapeutically effective amount of a KRAS G12C inhibitor and a TEAD inhibitor as disclosed above.

Also provided herein is a use of a therapeutic combination as disclosed herein in the manufacture of a medicament for the treatment of KRAS G12C-mediated cancers.

The examples that follow are not limiting but serve merely to illustrate the present disclosure.

Example 1 : Rav design combination experiment in KRAS mutant HOP-62 cell line using the KRAS G12C inhibitor N°1 and TEAD inhibitors N°1 and N°2

The NSCLC cell line HOP62 which carries a KRASG12C mutation was used for this study. HO-P62 cells were seeded in 384 well plates at 300 cells per well and incubated 24 hours at 37°C and 5% CO2. The KRAS G12C inhibitor N°1 used at 14 concentrations ranging from 10,000 nM to 0.006 nM was combined with TEAD inhibitors used at 18 concentrations ranging from 10,000 nM to 0.0001 nM, added to HOP-62 cells and incubated for 96 hours at 37°C and 5% CO2. Compound dilution and distribution to cells was performed on the TECAN MCA384 robotic platform. Cell proliferation was measured using Cell Titer Gio from PROMEGA (luminescence).

Three independent experiments with triplicates per experiment were performed and analyzed using the combination analysis software Combo2Screen. TEAD inhibitors were defined as non-active in this cell line, their effect on the KRAS G12C inhibitor was determined as an effect of potentiation and was quantified using the potentiation index based on the following equation: Potention only if Ki =

IC S oai = IC 6 Q of active compound with inactive compound at one concentration IC so a = IC 50 of active compound alone at one concentration

In this study, the different TEAD inhibitors potentiated the KRAS G12C inhibitor N°1 in HOP-62 KRAS G12C mutant NSCLC cells with a maximum effect of approximately eightfold, as exemplified below.

Example 2: Ray design combination experiment in KRAS mutant H-2030 cell lines using the KRAS G12C inhibitor N°1 and TEAD inhibitors N°1 and N°2

The NSCLC cell line H-2030 which carries a KRASG12C mutation was used for this study. H-2030 cells were seeded in 384 well plates at 250 cells per well and incubated 24 hours at 37°C and 5% CO2. The KRAS G12C inhibitor N°1 used at 14 concentrations ranging from 10,000 nM to 0.006 nM was combined with TEAD inhibitors used at 18 concentrations ranging from 10,000 nM to 0.0001 nM, added to H-2030 cells and incubated for 144 hours at 37°C and 5% CO2. Compound dilution and distribution to cells was performed on the TECAN MCA384 robotic platform. Cell proliferation was measured using Cell Titer Gio from PROMEGA (luminescence).

Three independent experiments with triplicates/experiment were performed and analyzed using the combination analysis software Combo2Screen. TEAD inhibitors were defined as non-active in this cell line, their effect on the KRAS G12C inhibitor was determined as an effect of potentiation and was quantified using the potentiation index based on the following equation: Potention only if Ki =

IC 50 ai = IC 50 of active compound with inactive compound at one concentration IC 50 a = IC 50 of active compound alone at one concentration

In this study, the different TEAD inhibitors potentiated the KRASG12C inhibitor N°1 in Fl- 2030 KRAS G12C mutant NSCLC cells with a maximum effect of approximately 18- to 33- fold, as exemplified below.

Example 3: IC50 shift experiment in the KRAS G12C mutant NSCLC cell line HOP-62 using the KRAS G12C inhibitors N°1 and N°2 and a set of structurally different TEAD inhibitors.

The KRAS G12C mutant NSCLC cell line HOP-62 was used for this study. Cells were seeded in 96 well plates at 1250 cells per well and incubated 24 hours at 37°C and 5% CO2. The KRAS G12C inhibitors N°1 and N°2 were used at 10 concentrations and combined with TEAD inhibitors used at 2 concentrations. Compound dilution and distribution to cells was performed on the TECAN MCA384 robotic platform. Cells were incubated with inhibitors for 144 hours at 37°C and 5% CO2. Cell proliferation was measured using Cell Titer Gio from PROMEGA (luminescence). For each KRAS G12C inhibitor, IC50 values in these cell lines were determined in the absence or presence of TEAD inhibitors.

In this study, the different TEAD inhibitors potentiate the IC50s of the KRAS G12C inhibitor N°1 or N°2 by up to 21 -fold in HOP-62 KRAS G12C mutant NSCLC cells.

(at 0.1 and 1 pM for the TEAD inhibitors and at ten concentrations from 10,000 nM to 0.3 nM with 3-fold dilution steps for IC50 determination of the KRAS G12C inhibitor) <7 geometric mean value on multiple sets of measures.

(at 0.1 and 1 pM for the TEAD inhibitors and at ten concentrations from 10,000 nM to 0.3 nM with 3-fold dilution steps for IC50 determination of the KRAS G12C inhibitor)

These tests on tumor models with KRAS G12C mutations show that the combination of specific TEAD inhibitors of the present disclosure with KRAS G12C inhibitors potentiates the effect of the KRAS G12C inhibitor by several orders of magnitude, in the above examples, between four to 33-fold, depending on the combination of inhibitors and cell lines used. The potentiation effects are observed in multiple different KRAS G12C models and essay set ups.
