AI Technical Summary
Existing EGFR tyrosine kinase inhibitors (TKIs) are prone to drug resistance when treating non-small cell lung cancer (NSCLC). Especially after the T790M mutation occurs, third-generation EGFR TKIs such as osimertinib are difficult to be effective in the long term.
EGFR TKI and AKT inhibitors were used in combination to enhance anti-proliferation and induce apoptosis effects. The method includes the use of EGFR TKI and AKT inhibitors in patients with EGFR mutation-positive NSCLC to cover the possible drug resistance mechanisms after EGFR inhibition.
By combining EGFR TKI and AKT inhibitors, tumors can be resensitized in some drug-resistant patients, delaying or preventing the emergence of drug resistance, thereby improving the long-term efficacy of the treatment.

Abstract
Description
[Technical field]
[0001] The present specification relates to an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) for use in the treatment of cancer (e.g., non-small cell lung cancer [NSCLC]), wherein the EGFR tyrosine kinase inhibitor (TKI) is administered in combination with an AKT inhibitor. [Background technology]
[0002] The discovery of activating mutations in epidermal growth factor receptor (EGFR) has revolutionized the treatment of the disease. In 2004, it was reported that activating mutations in exons 18-21 of EGFR correlate with the response of NSCLC to EGFR-TKI therapy (Non-Patent Document 1, Non-Patent Document 2). These mutations are estimated to occur in approximately 10-16% of human patients with NSCLC in the United States and Europe, and approximately 30-50% of human patients with NSCLC in Asia. The two most important EGFR activating mutations are exon 19 deletions and exon 21 missense mutations. Exon 19 deletions account for approximately 45% of known EGFR mutations. Eleven different mutations resulting in deletions of 3-7 amino acids have been detected in exon 19, all clustered around the uniformly deleted codons corresponding to amino acids 747-749. The most important exon 19 deletion is E746-A750. Missense mutations in exon 21 account for approximately 39 to 45% of known EGFR mutations, and among them, the substitution mutation L858R accounts for approximately 39% of all exon 21 mutations (Non-Patent Document 3).
[0003] Two first-generation (erlotinib and gefitinib), two second-generation (afatinib and dacomitinib) and one third-generation (osimertinib) epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are currently available for the management of EGFR mutation-positive NSCLC. All of these TKIs are effective in patients with NSCLC whose tumors harbor an in-frame deletion in exon 19 and an L858R point mutation in exon 21. These two mutations account for approximately 90% of all EGFR mutations. In approximately 50% of patients, resistance to first- and second-generation EGFR TKIs is mediated by the acquisition of the "gatekeeper" mutation, T790M. Currently, osimertinib is the only registered EGFR TKI that is active against exon 19 deletions and L858R mutations, independent of the presence of the T790M mutation. However, even patients treated with osimertinib eventually progress due to the development of acquired resistance, mainly due to other resistance mechanisms.Therefore, there remains a need to develop novel therapies for treating NSCLC, especially for patients whose disease has progressed after treatment with third-generation EGFR TKIs.
[0004] Induction of programmed cell death by apoptosis is a crucial mechanism of anticancer activity of osimertinib and other EGFR TKIs. However, certain cancers may develop (or be inherently) resistant to such apoptosis, reducing the effectiveness of treatment.
[0005] Through laboratory experiments with a population of cancer cells sensitive to osimertinib, it was found that the effect of EGFR TKIs could be enhanced in some patients by combined use with AKT inhibitors. AKT is a serine / threonine-specific protein kinase that plays a key role in multiple cellular processes such as glucose metabolism, apoptosis, cell proliferation, transcription and cell migration. Mammalian cells express three closely related AKT isoforms encoded by different genes: AKT1 (protein kinase Bα), AKT2 (protein kinase Bβ) and AKT3 (protein kinase Bγ). Exemplary AKT inhibitors include capivasertib or a pharma- ceutically acceptable salt thereof (also known as AZD5363, also known by the chemical name (S)-4-amino-N-(1-(4-chlorophenyl)-3-hydroxypropyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide), which is a selective inhibitor of all three AKT isoforms.
[0006] Without being bound by theory, it is proposed that in cancer cells that depend on the EGFR pathway, inhibiting this protein can induce a state in which cells are sensitive to AKT inhibitors. Cells that survive chronic treatment with EGFR TKI monotherapy may have defects in cell death and act as reservoirs for the development of clinical resistance. However, in a subset of these patients, the cellular adaptations that cancer cells require to avoid death in the presence of EGFR inhibition may reveal new vulnerabilities to AKT inhibitors.
[0007] In preclinical cell line models, a subpopulation of osimertinib-resistant cells showed enhanced sensitivity to AKT inhibitors compared with osimertinib-sensitive parental cells, suggesting that combining AKT with osimertinib may overcome emerging resistance and provide a potential avenue for treating patients whose cancers no longer respond to EGFR TKIs alone.
[0008] It was therefore determined that treatment with an AKT inhibitor could overcome such resistance and resensitize the cancer to the apoptotic effects of EGFR TKIs. Furthermore, a combination of an EGFR inhibitor and an AKT inhibitor could work together in therapy to prevent or delay the onset of resistance. [Prior art documents] [Non-patent literature]

[0010] Provided herein is a means of utilizing AKT inhibitors in combination with EGFR TKIs to enhance the anti-proliferative and pro-apoptotic effects of EGFR TKI treatment in cancer (eg, NSCLC).
[0011] Thus, the present specification discloses the combination of an EGFR TKI with an AKT inhibitor for EGFR mutated NSCLC, both as a first-line treatment (i.e., in patients who have not been treated with an EGFR TKI) and as a treatment at the minimal residual disease stage (i.e., in patients who have been previously treated with an EGFR TKI, where the combination treatment is initiated at the time of maximum drug response when the number of residual tumor cells is so low that it does not cause any physical signs or symptoms).
[0012] In one aspect, there is provided an EGFR TKI for use in treating cancer in a human patient, administered in combination with an AKT inhibitor.
[0013] The terms "treat", "treating" and "treatment" refer to at least partially alleviating, inhibiting, preventing and / or reversing a condition, disorder or disease, such as lung cancer. The term "cancer treatment" includes both in vitro and in vivo treatments, including in warm-blooded animals, such as humans. The effectiveness of cancer treatments can be evaluated in a variety of ways, including, but not limited to, inhibition of cancer cell proliferation (including reversal of cancer growth), promotion of cancer cell death (e.g., by promoting apoptosis or another cell death mechanism), amelioration of symptoms, duration of response to treatment, delay of disease progression and prolongation of survival. Treatments can also be evaluated with respect to the nature and extent of side effects associated with treatment. Additionally, efficacy can be evaluated with respect to biomarkers, such as levels of expression or phosphorylation of proteins known to be associated with certain biological phenomena. Other evaluations of efficacy are known to those skilled in the art.
[0014] The phrase "in combination with" and similar terms (including "concurrently") encompasses the administration of two or more active pharmaceutical ingredients to a subject, including simultaneous administration of separate compositions, administration of separate compositions at different times, or administration of a composition in which two or more active pharmaceutical ingredients are present.
[0015] In a further aspect, there is provided the use of an EGFR TKI in the manufacture of a medicament for treating cancer in a human patient, wherein the EGFR TKI is administered in combination with an AKT inhibitor.
[0016] In a further aspect, a method of treating cancer in a human patient in need of such treatment is provided, comprising administering to the human patient a therapeutically effective amount of an EGFR TKI, wherein the EGFR TKI is administered in combination with a therapeutically effective amount of an AKT inhibitor.
[0017] The term "effective amount" or "therapeutically effective amount" refers to an amount of a compound or combination of compounds described herein that is sufficient to achieve the intended use, including but not limited to disease treatment. Therapeutically effective amounts may vary depending on the intended use (in vitro or in vivo) or the subject and disease state to be treated (e.g., the subject's weight, age, and sex), the severity of the disease state, the method of administration, and the like, and can be readily determined by one of ordinary skill in the art. The term also applies to a dose that induces a particular response (e.g., the amount of apoptosis) in a target cell. The particular dose will vary depending on the particular compound selected, the administration regimen to be followed, whether the compound is administered in combination with other compounds, the timing of administration, the tissue to which the dose is administered, and the physical delivery system to which the compound is transported.
[0018] In a further aspect, there is provided a method of treating cancer in a human patient in need of such treatment, comprising administering to the human patient a first amount of an EGFR TKI and a second amount of an AKT inhibitor, wherein the first amount and the second amount together constitute a therapeutically effective amount.
[0019] In a further aspect, a pharmaceutical composition is provided comprising an EGFR TKI, an AKT inhibitor and a pharma- ceutically acceptable excipient.
[0020] The term "pharmaceutical acceptable" is used to specify that the subject (e.g., a salt, dosage form, or excipient (such as a diluent or carrier) is suitable for use in patients. Exemplary lists of pharmaceutical acceptable salts can be found in "Handbook of Pharmaceutical Salts: Properties, Selection and Use", P.H. Stahl and C.G. Wermuth, editors, Weinheim / Zurich: Wiley-VCH / VFiCA, 2002 or subsequent editions.
[0021] Pharmaceutically acceptable acid addition salts can be formed with inorganic and organic acids. Inorganic acids from which salts can be derived include, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, and phosphoric acid. Organic acids from which salts can be derived include, for example, acetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, and salicylic acid. Pharmaceutically acceptable base addition salts can be formed with inorganic and organic bases. Inorganic bases from which salts can be derived include, for example, sodium, potassium, lithium, ammonium, calcium, magnesium, iron, zinc, copper, manganese, and aluminum. Organic bases from which salts can be derived include, for example, primary, secondary, and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines, and basic ion exchange resins. Examples include isopropylamine, trimethylamine, diethylamine, triethylamine, tripropylamine and ethanolamine.

[0024] EGFR mutation-positive NSCLC, patient selection and diagnostic methods In embodiments, the cancer is characterized by a PIK3CA mutation (e.g., a gain-of-function mutation or a deletion, substitution, or insertion mutation, such as a PIK3CA H1047R Mutations, PIKC3A E453K Mutations, PI3K E542K Mutation or PIKC3A E545K PI3KCA mutation status can be determined by methods known in the art.
[0025] In embodiments, the cancer is PTEN deficient (e.g., comprises cancerous cells (e.g., a population of cancerous cells, such as a majority of cancerous cells) with a reduced normal amount (e.g., compared to non-cancerous cells of the same patient) or reduced function of the PTEN tumor suppressor protein). PTEN status can be determined by methods known in the art.
[0026] In embodiments, the cancer is lung cancer, such as non-small cell lung cancer (NSCLC).
[0027] In embodiments, the NSCLC is EGFR mutation-positive NSCLC.
[0028] In an embodiment, the EGFR mutation-positive NSCLC comprises an activating mutation in EGFR. In a further embodiment, the EGFR mutation-positive NSCLC comprises a non-resistant mutation. In a further embodiment, the activating mutation in EGFR comprises an activating mutation in exons 18-21. In a further embodiment, the activating mutation in EGFR comprises a deletion of exon 19 or a missense mutation in exon 21. In a further embodiment, the activating mutation in EGFR comprises a deletion of exon 19 or a L858R substitution mutation. In a further embodiment, the mutation in EGFR comprises a T790M mutation.
[0029] In embodiments, the EGFR mutation-positive NSCLC is locally advanced EGFR mutation-positive NSCLC.
[0030] In embodiments, the EGFR mutation-positive NSCLC is metastatic EGFR mutation-positive NSCLC.
[0031] In embodiments, the EGFR mutation-positive NSCLC is unsuitable for either curative surgery or radiation therapy.
[0032] There are many methods for detecting activating mutations of EGFR, which are known to those skilled in the art. Several tests suitable for use in these methods have been approved by the US Food and Drug Administration (FDA). These methods include both tumor tissue-based and plasma-based diagnostic methods. In general, EGFR mutation status is first evaluated using tumor tissue biopsy samples from human patients. If tumor samples are not available or are negative, EGFR mutation status can be evaluated using plasma samples. A specific example of a diagnostic test suitable for detecting EGFR mutations, and in particular for detecting exon 19 deletions, L858R substitution mutations, and T790M mutations, is the Cobas™ EGFR Mutation Test v2 (Roche Molecular Diagnostics).
[0033] Thus, in an embodiment, the EGFR mutation-positive NSCLC comprises an activating mutation in EGFR (e.g., an activating mutation in exons 18-21, e.g., a deletion in exon 19, a missense mutation in exon 21, and a resistance mutation such as the L858R substitution mutation and the T790M mutation), and the EGFR mutation status of the human patient has been determined using a suitable diagnostic test. In a further embodiment, the EGFR mutation status has been determined using a tumor tissue sample. In a further embodiment, the EGFR mutation status has been determined using a plasma sample. In a further embodiment, the diagnostic method uses an FDA approved test. In a further embodiment, the diagnostic method uses the Cobas™ EGFR Mutation Test (v1 or v2).

In a further embodiment, the human patient's disease has reached a maximal response during or after a previous treatment with osimertinib or a pharmaceutically acceptable salt thereof. The EGFR TKI treatment includes treatment with either a first generation, second generation, or third generation EGFR TKI, or a combination thereof.

[0169] Unless otherwise stated, all reagents were commercially available and were used as supplied.
[0170] Example 1: Activating mutations in PIK3CA promote resistance to osimertinib in vitro, which can be overcome by combination treatment with capivasertib. To preclinically test the hypothesis that activating mutations in PIK3CA promote resistance to osimertinib, we used CRISPR / Cas9 technology to transfect lung cancer cell line models with PIK3CA H1047R and PIK3CA E453KEach variant of PIK3CA was introduced into the PIK3CA-positive cells. Because the efficiency of knock-in using this technology is usually low, only a small proportion of cells were genetically modified, which was expected to mimic the emergence of simultaneous resistance mutations in tumors. This heterogeneous cell pool was then cultured under the selective pressure of osimertinib (100 nM) for 3 weeks to generate a cell pool resistant to osimertinib for downstream analysis. DNA sequencing (NGS and Sanger) of the final CRISPR cell pool of osimertinib selection confirmed the selective growth of PIK3CA H1047R-positive and PIK3CA E453K-positive cells, indicating that the inserted PIK3CA mutations conferred resistance to osimertinib.
[0171] PIK3CAm-induced resistance to osimertinib and its rescue by combination with capivasertib were analyzed in more detail by various experimental approaches, including the following:
[0172] a) Cell viability: The viability of osimertinib-resistant PC9-PIK3CAm cell pools was compared to parental PC9 cells when treated with osimertinib alone or in combination with capivasertib. PIK3CAm-induced resistance to osimertinib was determined by the EC 50 This was associated with an increase in PIK3CA expression, which could be partially rescued by co-treatment with capivasertib (Figures 1-3: PC9-PIK3CA treated with osimertinib 3 nM-10 μM alone or in combination with capivasertib 500 nM for 6 days). H1047R and PC9-PIK3CA E453K Cell-TiterGlo® assay in .
[0173] b) Caspase 3 / 7 activation assay: The osimertinib-induced apoptotic response in PC9-PIK3CAm cells was compared to PC9 parental cells by the Caspase-Glo® 3 / 7 assay, a luminescent assay that measures intracellular caspase-3 and caspase-7 activity. PIK3CAm-induced resistance to osimertinib was associated with a reduced apoptotic response that could not be restored by co-treatment with capivasertib (Figure 4).
[0174] c) Clonogenic assay: The proliferation of PC9-PIK3CAm cells was compared to parental PC9. Cells were cultured at low density (1.5 × 10 3 ) into 6-well plates and treated with osimertinib (160 nM) alone or in combination with capivasertib (500 nM). At the end of treatment (day 8), cells were stained with crystal violet and cell density (% surface) was quantified by ImageJ. As shown in Figure 5, PC9-PIK3Cam cells developed resistance to osimertinib, which could be partially rescued by combination with capivasertib.
[0175] d) Intracellular changes by WB analysis. Protein analysis by Western blot showed increased basal levels of pAKT, pERK and pS6 in PC9-PIK3CAm CRISPR cell pools compared to PC9 parental cells, indicating activation of downstream PI3K / AKT and MAPK signaling pathways in cells resistant to osimertinib. Treatment with osimertinib downregulated P-EGFR levels and MAPK signaling in both parental and PC9-PIK3CAm cells. However, in PC9-PIK3CAm cells, P-AKT and P-S6 levels were refractory to osimertinib treatment and could be partially reduced in a dose-dependent manner by co-treatment with osimertinib + capivasertib (Figure 6, PC9 and PC9 PIK3CAm cells treated with 160 nM osimertinib alone or in combination with 100 nM-300 nM-1 μM capivasertib for 4 h).
[0176] Example 2: Loss of PTEN promotes resistance to osimertinib in vitro, which can be overcome by combination treatment with capivasertib. To preclinically test the hypothesis that loss of PTEN promotes resistance to osimertinib, we deleted PTEN in two NSCLC cell lines (PC9 and HCC-827) by CRSIPR KO. DNA sequencing and WB analysis confirmed that the loss of PTEN in the generated PC9 cell lines and HCC-827 KO Loss of PTEN in ("PTEN knockout") cell lines was confirmed and resistance to osimertinib and rescue by combination with capivasertib was assessed by:
[0177] a) Cell viability: CTG (osimertinib 3 nM to 10 μM treatment, 6 days) reduced cell viability in HCC-827 PTEN KO cell lines and PC9 PTEN KO The sensitivity of the cell lines to osimertinib was compared with that of the parental cells. KO The cell lines exhibited resistance to osimertinib, as indicated by an increased EC50 of osimertinib, when compared to the parental HCC-827 cells (Figure 7). After 2–3 weeks of osimertinib treatment, PC9 PTEN KO The cells showed similar sensitivity to osimertinib when compared to the PC9 parental cells, and resistance emerged later (Figure 8). In this PC9 model, resistance was observed in PC9 PTEN cells treated with 160 nM osimertinib for 3 weeks compared to PC9 cells that had the same osimertinib exposure (PC9 NTC osimertinib, 3 weeks). KO This is associated with an increased EC50 in cells.
[0178] b) Clonogenic assay: HCC-827 PTEN treated with 160 nM osimertinib KO Cell lines and PC9 PTEN KO The proliferation of the cell lines was compared to the parental cells in a long-term assay. 3Cells were seeded at low density in 6-well plates and treated with 160 nM osimertinib, and cell density (% surface) was calculated at the end of treatment. After 3 weeks, HCC-827 PTEN KO The cells were more dense (20x) than the parental HCC-827, indicating that loss of PTEN resulted in osimertinib resistance. Co-treatment with 500 nM capivasertib resulted in partial rescue of osimertinib resistance (Figure 9). In the PC9 model, PC9 PTEN was downregulated when compared to the parental PC9 cells. KO A milder resistance phenotype was observed with only a 2× higher cell density (FIG. 10).
[0179] c) Intracellular changes by WB analysis. Protein analysis by Western blot showed that PC9 PTEN KO and HCC-827 PTEN KO Both HCC-827 and PTEN showed increased levels of P-AKT and P-S6. KO Unexpectedly, we also observed increased RAS-MAPK signaling in PC9 PTEN treated with osimertinib 160 nM for 3 weeks (Figure 11). KO Stable p-S6 levels were observed in cells (Figure 12). A dose-dependent downregulation of P-S6 levels was observed with capivasertib in combination with osimertinib (Figures 13 and 14).
[0180] d) Additional observations: - In the in vitro model HCC-827, resistance to osimertinib could be rescued by combination with capivasertib (Figure 15, CTG assay), consistent with the hypothesis that loss of PTEN promotes resistance. - In the in vitro model PC9, the combination of osimertinib + capivasertib was able to mildly sensitize cells to osimertinib (Figure 16, clonogenic assay).
[0181] Example 3: In vivo xenograft model Additionally, an in vivo model using patient-derived cell lines was used to investigate the activity of the combination.
[0182] a) PC9 PIKC3A H1047 Cell lines and PC9 PIKC3A E453K The cell lines were cultured in RPMI1640 supplemented with 10% FCS and incubated in a humidified incubator with 5% CO2 at 37°C. PC9 PIKC3A H1047 Xenografts and PC9 PIKC3A E453K Xenografts were implanted into the flanks of female NOD / SCID mice at 5 × 10 cells per animal in 100 μL of cell suspension containing 50% Matrigel. 6 Cells were established by subcutaneous implantation. All mice were over 6 weeks old at the time of cell implantation. Tumor growth was monitored twice weekly by bilateral caliper measurement, and tumor volume was calculated using the formula: TV (mm3) = [length (mm) x width (mm)2] x 0.5 (length and width are the longest and shortest diameters of the tumor).
[0183] PC9 PIKC3A H1047 and PC9 PIKC3A E453 is a CRISPR engineered cell line. Figures 17 and 18 show that the combination of an EGFR TKI with an AKT inhibitor enhances the response to treatment and slows growth even when treatment is stopped.
[0184] b) LC-F-12 tumor fragments from donor mice inoculated with primary human lung cancer tissue were collected and inoculated subcutaneously into the flanks of female athymic nude mice. Tumor growth was monitored twice weekly by bilateral caliper measurements, and tumor volume was calculated using the formula TV (cm3) = [length (cm) x width (cm)2] x 0.5 (length and width are the longest and shortest diameters of the tumor).
[0185] LC-F-12 is a PDX model derived from a patient who had not been treated with TKI. Figure 19 shows that the combination of EGFR TKI and AKT inhibitor enhances the response to treatment and delays growth even after treatment is stopped.
[0186] c) MR131 and CTG-2939 tumor fragments from donor mice inoculated with primary human lung cancer tissue were collected and inoculated subcutaneously into the flanks of female NSG mice. Tumor growth was monitored twice weekly by bilateral caliper measurements, and tumor volumes were measured as TV (cm). 3 ) = [length (cm) × width (cm)2] × 0.5 (length and width are the longest and shortest diameters of the tumor).
[0187] Figure 20 shows that the combination of an EGFR TKI and an AKT inhibitor induces tumor growth stasis in MR131, a model of acquired resistance due to loss of PTEN. Similarly, Figure 21 shows that the combination exhibits superior activity and induces tumor growth stasis compared to EGFR TKI monotherapy in CTG-2939, a model of acquired resistance due to loss of PTEN.
[0188] d) CTG-2180 tumor fragments from donor mice inoculated with primary human lung cancer tissue were collected and inoculated subcutaneously into the flanks of female athymic nude mice. Tumor growth was monitored twice weekly by bilateral caliper measurements, and tumor volumes were expressed as TV (cm). 3 ) = [length (cm) x width (cm) 2 ]×0.5 (where length and width are the longest and shortest diameters of the tumor).
[0189] FIG. 22 shows that the combination of an EGFR TKI with an AKT inhibitor induces superior tumor regression compared to EGFR TKI monotherapy in CTG-2180, a PDX model derived from a TKI-naive patient.
[0190] e) PC9 PTEN-KO and HCC827 PTEN-KO cell lines were cultured in RPMI1640 supplemented with 10% FCS and incubated in a humidified incubator with 5% CO2 at 37°C. PC9 PTEN-KO and HCC827 PTEN-KO xenografts were implanted into the flanks of female NOD / SCID and nude mice, respectively, at 5 × 10 cells per animal in 100 μL of cell suspension containing 50% Matrigel. 6 Cells were established by subcutaneous implantation. All mice were over 6 weeks old at the time of cell implantation. Tumor growth was monitored twice weekly by bilateral caliper measurement, and tumor volumes were calculated as TV (mm 3 ) = [length (mm) × width (mm)2] × 0.5 (where length and width are the longest and shortest diameters of the tumor).
[0191] Figure 23 shows that there is no evidence of benefit of combining osimertinib and capivasertib in the PTEN KO CRISPR engineered model in vivo, and Figure 24 shows that the degree of resistance to osimertinib in the PC9 / HCC827 PTEN KO model in vivo is minimal at best, thus limiting the opportunity to detect combination benefit.
