Abstract
A combination comprising a Mcl-1 inhibitor and a second anticancer agent, wherein the second anticancer agent is selected from anthracyclines, cytarabine and hypomethylating agents, and compositions and uses thereof.
Description
COMBINATION OF A MCL-1 INHIBITOR AND A STANDARD OF CARE TREATMENT FOR HEMATOLOGIC CANCERS,
USES AND PHARMACEUTICAL COMPOSITIONS THEREOF
FIELD OF THE INVENTION
The présent invention relates to a combination of a Mcl-1 inhibitor with a second anticancer agent, wherein the second anticancer agent is selected from anthracyclines (such as idarubicin, daunorubicin...), cytarabine (also known as cytosine arabinoside or ara-C) and hypomethylating agents (such as decitabine, azacitidine...). The présent invention relates to a combination of a Mcl-1 inhibitor with a second anticancer agent, wherein the second anticancer agent is selected from idarubicin, daunorubicin, mitoxantrone, cytarabine, decitabine, azacitidine and guadecitabine, more particularly idarubicin, daunorubicin, cytarabine, decitabine and azacitidine. The invention also relates to the use of said combination in the treatment of cancer, in particular hématologie cancer, and more particularly acute myeloid leukemia (AML), myelodysplastic syndromes, acute lymphocytic leukemia (ALL) and lymphoma. Also provided are pharmaceutical formulations suitabie for the administration of such combinations.
The presence of multiple acquired mutations within multiple clones in each AML case makes the concept of successful sélective targeting particularly difficult. This invention proposes the concept that cancers with diverse and multi-clonal molecular compositions may be successfully treated with the combination of an inhibitor of Mcl-1 and a cytotoxic drug able to effectively activate cellular apoptosis in a promiscuous manner, thereby leading to broad-based cell death of cancer cells beyond that achieved using Mcl-1 inhibitors or standard-of-care (SOC) chemotherapy separately. This approach could lead to enhanced rates of remission and increased clearance of minimal residual disease in the induction chemotherapy setting and this may lead to reduced rates of disease relapse and higher overall cure rates in AML as an example. AML is proposed as a model example due to the ability to quantitatively measure changes in clonal composition serially with treatment using digital PCR and RT-qPCR.
Inhibitors of Mcl-1 when combined with low-dose SOC chemotherapy could enhance the targeting of leukemic stem and progenitor cells by lowering the apoptotic threshold. This approach could be used in the post-remission setting as a maintenance therapy approach to eliminate residual AML stem cells and pre-leukemic stem cell clones comprised of diverse
-2molecular and cytogenetic abnormalities. The principle of demonstrating the éradication of leukemic and pre-leukemic progenitors will be demonstrated by reducing levels of clonal minimal residual disease or pre-leukemic clones as measured in differentiated mononuclear cells in the post-remission setting after exposure to Mcl-1 inhibitors in combination with SOC chemotherapy.
BACKGROUND OF THE INVENTION
Apoptosis is a highly regulated cell death pathway that is initiated by various cytotoxic stimuli, including oncogenic stress and chemotherapeutic agents. It has been shown that évasion of apoptosis is a hallmark of cancer and that effîcacy of many chemotherapeutic agents is dépendent upon the activation of the intrinsic mitochondrial pathway. Three distinct subgroups of the Bcl-2 family proteins control the intrinsic apoptosis pathway: (i) the pro-apoptotic BH3 (the Bcl-2 homology 3)-only proteins; (ii) the pro-survival members such as Bcl-2 itself, Bcl-xl, Bcl-w, Mcl-1 and Bcl-2al; and (iii) the pro-apoptotic effector proteins BAX and BAK (Czabotar et al., Nature Reviews Molecular Cell Biology 2014, 15, 49-63). Overexpression of the anti-apoptotic members of Bcl-2 family is observed in many cancers, particularly in hematological malignancies such as mantle cell lymphoma (MCL), follicular lymphoma/diffuse large B-cell lymphoma (FL/DLCL) and multiple myeloma (Adams and Cory, Oncogene 2007, 26, 1324-1337). Pharmacological inhibition of the anti-apoptotic proteins Bcl-2, Bcl-xl, Bcl-w and Mcl-1 by the recently developed BH3-mimetics drugs such as ABT-199 (venetoclax), ABT-263 (navitoclax) and S63845 has emerged as a therapeutic strategy to induce apoptosis and cause tumor régression in cancer (Zhang et al., Drug Resist. Updat. 2007, 10, 207-217; Kotschy et al., Nature 2016, 538, 477-482). Nevertheless, mechanisms of résistance to BH3 mimetics hâve been observed (Choudhary et al., Cell Death and Disease 2015, 6, el593) and the use of combination thérapies could improve effîcacy and delay or even abrogate résistance development.
Acute myeloid leukemia (AML) is a rapidly fatal blood cancer arising from clonal transformation of hematopoietic stem cells resuiting in paralysis of normal bone marrow function and deaths due to complications from profound pancytopenia. AML accounts for % of ail adult leukemias, with the highest incidence rates occurring in the United States, Australia and Europe (WHO. GLOBOCAN 2012. Estimated cancer incidence, mortality and prevalence worldwide in 2012. International Agency for Research on Cancer). Globally, there are approximately 88,000 new cases diagnosed annually. AML continues to 5 hâve the lowest survival rate of ail leukemias, with expected 5-year survival of only 24 %.
Current thérapies for the treatment of AML include the administration of cytarabine alone or in combination with an anthracycline such as daunorubicin or idarubicin. Low-dose cytarabine treatment and demethylating agents such as azacitidine and decitabine are also recommended as low-intensity options for patients who are inéligible for intensive chemotherapy (Dohner et aL, DOI 10.1182/blood-2016-08-733196). Although the standard therapy for AML (cytarabine in combination with anthracyclines) was conceived over 4 décades ago, the introduction of successful targeted thérapies for this disease has remained an elusive goal. The concept of targeted therapy in AML has been hampered by the realization that this disease evolves as a multi-clonal hierarchy, with rapid outgrowth of leukemic sub-clones as a major cause of drug résistance and disease relapse (Ding et al., Nature 2012, 481, 506-510). Recent clinical investigations hâve demonstrated the efficacy of Bcl-2 inhibitors in the treatment of AML (Konopleva et aL, American Society of Hematology 2014, 118).
There remains a need for new treatments and thérapies for the treatment of hématologie 20 cancer, in particular AML, myelodysplastic syndromes, ALL and lymphoma, and more particularîy for the treatment of AML. The présent invention provides a novel combination of a Mcl-1 inhibitor and a second anticancer agent, wherein the second anticancer agent is selected from anthracyclines, cytarabine and hypomethylating agents, more particularîy idarubicin, daunorubicin, mitoxantrone, cytarabine, decitabine, azacitidine and 25 guadecitabine, and more preferably idarubicin, daunorubicin, cytarabine, decitabine and azacitidine. The results show that the Mcl-1 inhibitor in combination with a second anticancer agent, wherein the second anticancer agent is selected from idarubicin, cytarabine and decitabine interacts synergistically in AML cell lines (Figure 1; Tables 3, 4 and 5). We also show that the combination of a Mcl-1 inhibitor with a second anticancer 30 agent, wherein the second anticancer agent is selected from idarubicin or decitabine exhibits a synergistic pro-apoptotic activity in primary human AML samples (Figures 2 and 6; Table 6). We also show that a subset of primary AML samples were sensitive to the combination of a Mcl-1 inhibitor with cytarabine whereas normal human CD34+ progenitor cells were résistant to the same dose (Figure 3). We also show that Mcl-1 5 inhibitor combined with decitabine was well-tolerated without losing weight during treatment and yet leads to enhanced activity against human AML in a patient-derived xenograft model in vivo (Figures 4, 5 and 6). Finally, we show that the combination of a Mcl-1 inhibitor with cytarabine could provide benefit to the treatment of ALL patients (Table 7).

PHARMACOLOGICAL DATA
EXAMPLE 1: In vitro effect on prolifération of combining MCL-1 inhibitors with idarubicin, cytarabine and decitabine in Acute Myeloid Leukemia (AML) cell lines
Material and method
Cell lines were sourced and maintained in the basic media supplemented with FBS as indicated in Table 1. In addition, ail media contained penicillin (100 lU/mL), streptomycin (100 pg/mL) and L-glutamine (2 mM).
Cell lines were cultured at 37 °C in a humidified atmosphère containing 5 % CO2 and expanded in T-150 flasks. In ail cases cells were thawed from frozen stocks, expanded through > 1 passage using appropriate dilutions, counted and assessed for viability using a CASY cell counter prior to plating 150 pL/well at the densities indicated in Table 1 into 96-well plates. Ail cell lines were determined to be free of mycoplasma contamination inhouse. Stock solutions of compounds were prepared at a concentration of 5 mM in DMSO and stored at -20 °C.
In order to analyse the activity of the compounds as single agents, cells were seeded and treated with nine 2-fold serial dilutions of each compound dispensed individually directly into the cell assay plates. Effects of the compounds on cell viability were assessed after 3 days of incubation at 37 °C/5 % CO2 by quantification of cellular ATP levels using CellTiterGlo at 75 pL reagent/well. Ail the experiments were performed in triplicates. Luminescence was quantified on a multipurpose plate reader. Single agent IC50S were calculated using standard four-parametric curve fitting. IC50 is defined as the compound concentration at which the CTG signal is reduced to 50 % of that measured for the vehicle (DMSO) control (Table 2).
In order to analyse the activity of the compounds in combination with cytarabine (Table 3), idarubicin (Table 4) and decitabine (Table 5), cells were seeded and treated with seven or eight 3.16-fold serial dilutions of each compound dispensed, either individually or in ail possible permutations in a checkerboard fashion, directly into the cell assay plates as indicated in Figure 1. Effects of the single agents as well as their checkerboard combinations on cell viability were assessed after 3 days of incubation at 37 °C/5 % CO2 by quantification of cellular ATP levels using CellTiterGlo at 75 pL reagent/welL Two
-38independent experiments, each one performed in duplicates, were performed. Luminescence was quantified on a multipurpose plate reader.
Potential synergistic interactions between compound combinations were assessed using the Excess Inhibition 2D matrix according to the Loewe additivity model and are reported as 5 Synergy Score (Lehar et al., Nature Biotechnology 2009, 27(7), 659-66). Ail calculations were performed using Chalice™ Bioinformatics Software available in Horizon website.
The doubling time indicated in Table 1 is the mean of the doubling time obtained in the different passages (in T-150 flasks) performed from the thawing of the cells to their seeding in the 96-weel plates.

Synergy Scores above 2 (Lehar et al, 2009)) for the majority of the cell lines tested was observed (Tables 3, 4 and 5). These data indicate that the combination of Mcl-1 inhibitors
-42with the standard-of-care drugs for the treatment of hématologie cancer could provide benefit to the treatment of AML patients.
EXAMPLE 2: Synergistic pro-apoptotic activity of combining MCL-1 inhibitors with idarubicin in primary human AML samples
Material and method: Patient AML cells
Bone marrow samples from patients with AML were collected after informed consent in accordance with guidelines approved by The Alfred Hospital Human research ethics committee.
Mononuclear cells were isolated by density-gradient centrifugation Ficoll-Hypaque (GE 10 Healthcare, Austral ia) density-gradient centrifugation and red cell lysis was performed using 0.156 M NH4CI, 0.017 M Tris-HCl pH 7.2 as previously described (Rijal et al., Blood 2015, 125, 2815-2824). Cells were then re-suspended in phosphate-buffered saline containing 2 % Fêtai Bovine sérum (FBS; Sigma, Australia). Mononuclear cells were then suspended in RPMI-1640 (GIBCO, Australia) medium containing penicillin and 15 streptomycin (GIBCO) and heat inactivated fêtai bovine sérum 15 % (Sigma). Cells were washed in phosphate-buffered saline (PBS) containing 2 % FBS prior to use.
Cell viability assays
Freshly purified mononuclear cells from AML patient samples were adjusted to a concentration of 2.5 x 105/mL and 100 pL of cells aliquoted per well into 96 well plates 20 (Sigma). Cells were then treated with idarubicin and Compound 2 over a 5 log concentration range from 1 nM to 10 μΜ for 48 hours. For combinations assays, drugs were added at a 1:1 ratio from 1 nM to 10 μΜ and cells were incubated at 37 °C 5 % CO2. Cells were then stained with Sytox blue nucleic acid stain (Invitrogen, Australia) and fluorescence measured by flow cytométrie analysis using the LSR-II Fortessa (Becton 25 Dickinson, Australia). FACSDiva software was used for data collection, and FlowJo software for analysis. Blast cells were gated using forward and side scatter properties. Viable cells excluding Sytox blue were determined at 6 concentrations for each drug and the 50 % léthal concentration (LC50, in μΜ) determined.

Results
The effect on survival of combining the Mcl-1 inhibitors of the invention with idarubicin was assessed in several primary human AML samples (Figure 2; Table 6). Even if several samples are sensitive to Mcl-1 inhibitors and standard-of-care drugs for the treatment of AML as monotherapy, a larger number of samples wherein the monotherapy is ineffective or poorly effective are synergistically sensitive to the combination of Mcl-1 inhibitors with
-44standard-of-care drugs for the treatment of hématologie cancer showing that the combination could provide benefît to the treatment of AML patients.
EXAMPLE 3: Leukemic blasts displayed greater sensitivity to Mcl-1 inhibitors combined with cytarabine than CD34+ hematopoietic precursors
Material and method: Colony Assays
Colony forming assays were performed on freshly purified and frozen mononuclear fractions from AML patients.
Primary cells were cultured in duplicate in 35 mm dishes (Griener-bio, Germany) at 1 x 104 to 1 x 105. Cells were plated in 0.6 % agar (Difco, Australia): AIMDM 2x (IMDM powder-Invitrogen, supplemented with NaHCCh, dextran, Pen/Strep, B mercaptoethanol and asparagine): Fêtai Bovine Sérum (Sigma) at a 2:1:1 ratio. For optimal growth conditions ail plates contained GM-CSF (100 ng per plate), IL-3 (lOOng/plate R&D Systems, USA), SCF (100 ng/plate R&D Systems) and EPO (4 U/pIate). Growth was for 2-3 weeks in the presence and absence of drug at 37 °C at 5 % CO2 in a high humidity incubator. After incubation plates were fixed with 2.5 % glutaraldehyde in saline and scored using the GelCount from Oxford Optronix (Abingdon, United Kingdom).
Results
In clonogenic assays, a subset of primary AML samples and normal human CD34+ progenitor cells were résistant to 100 nM Compound 2. By contrast, the standard-of-care drugs, such as cytarabine 10 nM, were toxic to clonogenic growth of both leukemic and normal progenitor cells. Finally, a subset of primary AML samples was sensitive to 10 nM Compound 2 + cytarabine, whereas normal human CD34+ progenitor cells were less affected by this dose (Figure 3).
EXAMPLE 4: Mcl-1 inhibitor combined with decitabine is well tolerated in vivo
To détermine the tolerability of Compound 2 in combination with decitabine, NSG mice were treated with:
a) decitabine 0.4 mg/kg or 0.8 mg/kg IP injection, or
b) decitabine 0.4 mg/kg or 0.8 mg/kg in combination with Compound 2 25 mg/kg (IV), over 1 week and white blood cells (WBC), platelet, hemoglobin (Hb), red blood cells (RBC) counts were determined using the Hemavet blood analyzer.
Compound 2 combined with decitabine was well-tolerated (Figure 5) and mice did not lose weight during treatment (Figure 4).
Taken altogether, Examples 2, 3 and 4 show that the combination of a Mcl-1 inhibitor and a standard-of-care drug for the treatment of hématologie cancer is a novel approach to treating in particular AML, without need for additional chemotherapy and with an acceptable therapeutic safety window.
EXAMPLE 5: Mcl-1 inhibitor combined with decitabine synergistically inhibits PDX AML in vivo
Material and method
Bone marrow leukemic blasts from AML patient sample AML54 were intravenously injected into NOD—IL2Rycnull (NRG) mice (The Jackson Laboratory, Bar Harbor, USA) for expansion. The NRG-SG3 mice were monitored for leukemia development by flow cytométrie analysis of peripheral blood for human CD45-positive (hCD45+) cells. To establish mouse models of patient primary AML, 1 x 106 leukemic blasts were injected into NRG-SG3 mice via tail-vein injection and animais monitored for leukemia progression using flow cytométrie analysis of peripheral blood for hCD45+ cells. hCD45+ cell counts in the bone marrow from the fémurs of euthanized animais were used to détermine the extent of leukemia infiltration. Bone marrow cells were extracted by flushing fémurs in PBS supplemented with 2 % fêtai bovine sérum. To détermine efficacy on AML, cohorts of mice were treated with vehicle control, decitabine (0.4 mg/kg) daily IP
-46for 5 days, twice weekly IV injection with Compound 2 (Mcl-1 inhibitor, 25 mg/kg) or decitabine in combination with Compound 2. Drug efficacy was determined by flow cytométrie analysis of hCD45+ cells in bone marrow isolated from fémurs of mice in vehicle.
Results
As shown in Figure 6, there was a remarkable decrease in human AML cell numbers in mice treated by decitabine in combination with Compound 2, with hCD45+ cells accounting for less than 9 % of bone marrow leukocytes. These results indicate that combination of a Mcl-1 inhibitor and a standard-of-care drug for the treatment of hématologie cancer effectively kills the bulk human AML blast cells in the PDX model of AML54.
EXAMPLE 6: Synergistic pro-apoptotic activity of combining MCL-1 inhibitors with standard-of-care drugs in primary human ALL samples
Material and method: Primary ALL patient samples
Bone marrow or peripheral blood samples from patients with ALL were collected after informed consent in accordance with guidelines approved by The Alfred Hospital Human research ethics committee. Mononuclear cells were isolated by Ficoll-Paque (GE Healthcare, Australia) density-gradient centrifugation, followed by red cell déplétion in ammonium chloride (NH4CI) lysis buffer at 37 °C for 10 minutes. Cells were then resuspended in phosphate-buffered saline containing 2 % Fêtai Bovine sérum (Sigma, Australia). Mononuclear cells were then suspended in RPMI-1640 (GIBCO, Australia) medium containing penicillin and streptomycin (GIBCO) and heat inactivated fêtai bovine sérum 15 % (Sigma).
Cell Viability
Freshly purified mononuclear cells from ALL patient samples were adjusted to a concentration of 2.5 x 105/ml and 100 pL of cells aliquoted per well into 96 well plates (Sigma). Cells were then treated with indicated drugs over a 6 log concentration range
-47from 1 nM to 10 μΜ for 48 hours. For combinations assays, drugs were added at a 1:1 ratio from 1 nM to 10 μΜ and incubated at 37 °C 5 % CO2. Cells were then stained with sytox blue nucleic acid stain (Invitrogen, Australia) and fluorescence measured by flow cytométrie analysis using the LSR-II Fortessa (Becton Dickinson, Australia). FACSDiva 5 software was used for data collection, and FlowJo software for analysis. Blast cells were gated using forward and side scatter properties. Viable cells excluding sytox blue were determined at 6 concentrations for each drug and the 50 % léthal concentration (LC50, in μΜ) determined.

EXAMPLE 7: Mcl-1 inhibitor combined with decitabine synergistically inhibits PDX AML in vivo
Material and method
To establish mouse models of primary patient AML, 1x106 leukemic blasts were injected into NOD-IL2Rcynu11 (NRG-SG3) mice (The Jackson Laboratory, Bar Harbor, ME, USA) via tail-vein injection and animais monitored for leukemia progression using flow cytométrie analysis of peripheral blood for hCD45+ cells. hCD45+ cell counts in the bone marrow from the fémurs of euthanized animais were used to détermine the extent of leukemia infiltration. Bone marrow cells were extracted by flushing fémurs in PBS supplemented with 2 % fêtai bovine sérum. To détermine the effîcacy of Compound 1 plus decitabine, mice received Compound 1 25 mg/kg twice weekly IV and decitabine IP daily (D1-D5) 0.4 mg/kg. Drug effîcacy was determined by flow cytométrie analysis of hCD45+ cells in bone marrow isolated from flushed fémurs. Sternums were fixed in formalin, sectioned and stained with hematoxylin and eosin or anti-hCD45 to assess leukemic burden and cellularity.
Results
The results obtained show that the combination of Mcl-1 inhibitors with standard-of-care drugs for the treatment of hématologie cancer could provide benefit to the treatment of AML patients.
