Description

[0001] TRIPLE KINASE INHIBITION FOR THE TREATMENT OF TYPE I INTERFERON RESPONSE ASSOCIATED DISORDERS FIELD OF THE INVENTION [1] The invention describes a novel combination therapy strategy and screening approaches, 5 comprising a Receptor-interacting serine / threonine-protein kinase 1 (RIPK1) inhibitor, an inhibitor IκB kinase epsilon (IKKε), and a TANK binding kinase 1 (TBK1) inhibitor for the treatment and / or prevention of diseases associated with a modulated immune response, such as disorders associated with a type I interferon response. The invention provides such inhibitory compounds and their specific combinations for use in medical applications, as well as pharmaceutical 10 compositions comprising the compounds of the invention. The invention further pertains to a method of treatment and / or prevention of a proliferative disease in a subject, the method comprising administering to the subject as single treatments or one or more combinatorial treatments, either sequentially or concomitantly, a therapeutically effective amount of inhibitors of RIPK1, inhibitors of IKKε – signaling, and inhibitors of TBK1. Further provided are approaches for 15 screening and testing candidate kinase inhibitors for their applicability in a triple combination in accordance with the invention. DESCRIPTION [2] The IkappaB kinase (IKK)-related serine / threonine kinases TBK1 and IKKε elicit anti-viral type-I interferon (IFN) response downstream of nearly all DNA and RNA sensors (Fitzgerald et 20 al., 2003; Hemmi et al., 2004; Yamamoto et al., 2003). TBK1 induces IFN responses downstream of the pathogen recognition receptors (PRRs) RIG-I and MDA5; cyclic GMP-AMP (cGAMP) synthase (cGAS); and TLR3 and TLR4, which transduce signals through the adaptor proteins MAVS, STING and TRIF, respectively. Upon ligand engagement, TBK1 phosphorylates the adaptor proteins MAVS, STING and TRIF, which results in the recruitment of the transcription 25 factor IRF3. IRF3 is then phosphorylated by TBK1, leading to its homo-dimerization and nuclear translocation. This cascade of events culminates in the induction of the expression of type I interferons and proinflammatory cytokines downstream of these nucleic acid sensors. Recognition of viral and bacterial nucleic acids in the cytosol or endosomal compartments and activation of TBK1 / IKK ^-dependent interferon and cytokine expression is important for host 30 defence. However, in addition to their important role in anti-viral immunity, type I interferons and cytokines critically contribute to the pathogenesis of a broad range of diseases characterized by autoinflammation and autoimmunity such as systemic lupus erythematosus (SLE) and Aicardi- Goutières Syndrome (AGS). Such diseases are often associated with abnormal regulation of nucleic acid metabolism and / or sensing and are collectively described under the term of type I 35 interferonopathies. Recognition of both endogenous and exogenous nucleic acids by innate immune receptors can trigger inflammation, because the capacity of innate sensors to discriminate between foreign and host nucleic acids is only limited. Mice lacking genes involved in DNA degradation such as DNAsel or DNAse1l3 and DNAse3 (also known as Trex1) display systemic lupus erythematous-like (SLE) pathology, and inflammatory myocarditis with 5 autoimmune-like pathology, respectively. In humans, mutations in the DNaseI or DNaseIl3 and DNase2a genes are respectively associated to SLE and deforming arthropathy, while mutations in the DNase3 gene is linked to chilblain lupus erythematous and Aicardi-Goutieres Syndrome (AGS). Studies in genetic mouse models showed that the genetic deletion of STING, IFNAR1 and IRF3 – together with IRF7 in the case of DNAse2a-deficient mice - rescues the myocarditis 10 phenotype of DNAse3-deficient mice and the embryonic lethal phenotype of DNAse2-deficient mice. Moreover, gain of function mutations in STING resulting in ligand-independent constitutive activation of TBK1 / IKK ^-mediated interferon and cytokine production also cause the pathogenesis of autoinflammatory lupus-like pathologies (Liu et al., 2014). In addition to abnormal activation of the DNA sensing machinery, genetic defects in proteins regulating RNA sensing have 15 also been linked to the pathogenesis of autoinflammatory and autoimmune pathologies. Mutations in ADAR1, an enzyme that deaminates adenosine in RNA and thus prevents its recognition by MDA5, are found in patients with AGS and mice lacking ADAR1 or its deaminase activity develop inflammatory pathologies (Heraud-Farlow and Walkley, 2016). [3] Together, the prior art shows that abnormal activation of interferon and cytokine production 20 caused by mutations affecting the nucleic acid sensing signalling machineries induce the pathogenesis of autoinflammatory and autoimmune diseases such as type I interferonopathies. Because of their essential function in inducing type I interferon and cytokine responses downstream of nucleic acid sensors, TBK1 and IKKε are therefore attractive therapeutic targets for the treatment of interferonopathies and other diseases triggered by abnormal activation of the 25 nucleic acid sensing and signalling machineries. In addition, TBK1 has been implicated in the pathogenesis of diet-induced obesity and metabolic disease (Zhao et al., 2018), suggesting that TBK1 inhibition could have a therapeutic effect in obesity-associated diseases. [4] The roles of TBK1 and IKK ^ have been studied using mice engineered to lack these kinases by disrupting the respective genes (these are referred to as ‘knockout’ mice). Mice lacking 30 IKK ^ were reported to be viable and fertile and did not develop any apparent pathology under steady state conditions, showing that IKK ^ is not essential for normal mouse development and physiology (Hemmi et al., 2004; Tenoever et al., 2007). In contrast, Tbk1- / -mice died during embryonic development due to TNFR1-mediated death of foetal liver cells (Bonnard et al., 2000). [5] Therefore, there is a continued need in the art to provide treatment strategies to tackle 35 immunological pathologies such as type I interferonopathies. It is an object of the present invention to meet that need.

[0002] EXAMPLES

[0105] Certain aspects and embodiments of the invention will now be illustrated by way of example and with reference to the description, figures and tables set out herein. Such examples of the methods, uses and other aspects of the present invention are representative only, and should not be taken to limit the scope of the present invention to only such representative examples. Material and Methods

[0106] Mice (sequences are shown in sequence listing in SEQ ID Nos: 4 to 16)

[0107] The generation of Ripk1D138Nmice were previously described (Polykratis et al., 2014). Trex1ko, Tbk1D135N, and IkbkeK38Amice were generated using CRISPR / Cas9 technology. Of note, Trex1 is a single exon gene. For Trex1komice, a short-guide (sg)RNA (5’- TTCCAGGTCTAAGAAGATGA -3’) and (5’- CCTGGGCAGTAAGTCAA GAG, for Tbk1D135Nmice, a short-guide (sg)RNA (5′- TGTTGCCTGGCTTGATAT CT - 3′) and long single stranded(ss) oligonucleotide (5′- AAATCCGTGAGTTTGTACACAGACTGGCCGTCCTCCCCTATGACGCGCATGATG TTGCCTGGCTTGATATtTCGaTGCACTATGCCGTTCTCTCGGAGATGATTCATCC CGCCCACTTCAGCAATAGGTACAAAACAAAGG -3′), and for IkbkeK38Amice a sgRNA (5′- CGGGGAGGTGGTTGC TGTAA-3′) and long ss oligonucleotide (5′- GCAGAGGTGGTCCCCATTGCTTACTCTCGCCCTGTGCCCACGCTAGAAATCCG GGGAGGTGGTTGCTGTAgctGTCTTCAACTCAGCCAGCTATCGGCGACCTCCTG AGGTTCAGGTGAGGGAGTTTGAGGTCCTGCGGAGGC -3′) and co-injected into fertilized wild- type oocytes together with Cas9 protein and mRNA.

[0108] The deletion of Trex1 exon was confirmed using the following primers: (5’- ATCCCAC TAGAACAACCCTGCC -3’) and (5’- TTCAGACTCCGCACCCTCATTT - 3’). For genotyping of IkbkeK38Amice, 330bp region spanning the mutation site of Ikbke were amplified using Universal Forward (5′- ACC CTT GAG GGA CAT CAG GT -3′) and Universal Reverse (5’- CGATGTTCTGGTGATTCAGCCT -3’), and WT (259bp) and mutant (107bp) sequence were respectively amplified using WT Reverse (5’- GCTGGCTGAGTTG AAGACCTTT -3’) and (5’- GGA GGT GGT TGC TGT AGC TG -3’) primers in a single PCR reaction. TBK1- D135N mutation destroyed the EcoRV restriction site on this genomic region. For genotyping of the Tbk1D135Nallele, the amplicon generated with primers (5’- ACTCCACATAGAACGTGCCTC - 3’) and (5’ ACACACTTGTGCCTGA GGATT -3’) were incubated with EcoRV-HF (Neb, cat no R3195) restriction enzyme for 90 minutes at 37°C. PCR amplicons were visualized on 2.0% agarose gels stained with ethidium bromide.

[0109] Mice were maintained at the specific-pathogen-free (SPF) animal facilities of the Institute for Genetics and the CECAD Research Center of the University of Cologne. All mouse procedures were conducted in accordance with national and institutional guidelines, and protocols were approved by the responsible local authorities in Germany (Landesamt für Natur, Umwelt und 5 Verbraucherschutz Nordrhein- Westfalen). Mice of the indicated genotype were assigned at random to groups and experiments were not blinded. Both male and female mice are included in all groups.

[0110] Blood analysis

[0111] Blood-cell-count analysis was performed in 40µl of peripheral blood using an Abacus 10 Junior Vet analyser according to the manufacturer's instructions.

[0112] Isolation and culture of bone marrow derived macrophages

[0113] For the preparation of BMDMs, bone marrow cells were plated on 145 mm bacterial Petri dishes (Greiner, cat no 639161_120) in DMEM medium (Invitrogen, cat no 41965062) supplemented with 20ng / ml mM-CSF (ImmunoTools, cat no.12343113), 10% fetal calf serum, 15 penicillin / streptomycin and sodium pyruvate. The cells were plated in tissue-coated dishes at Day 6 of culture. The experiments were performed on Day 7 of culture. The BMDMs were stimulated with MRT67307 (Selleckchem, cat no. S7948) or 100ng / ml ultrapure LPS (Enzo Life Sciences, cat no. ALX-581–010- L002) before the collection of samples.

[0114] Cytokine analysis 20

[0115] The cytokine levels in the supernatants from macrophage cultures were determined by ELISA kits for IL-1α (Thermo Scientific, cat no.88–5019–22), IL-1β (Thermo Scientific, cat. no. 88–7013–88), and IFNβ (Biolegend, cat no. BLD-43907) according to the manufacturers' instructions.

[0116] Immunoblotting 25

[0117] Cell lysates were denatured in 2×Laemmli buffer (Biorad, cat no 34095) supplement with 4% β-mercaptoethanol and 10mM Dithiothreitol. The protein samples were subsequently boiled at 95 °C for 4 minutes and separated by NuPageTM(Thermo Scientific, cat no. NP0336BOX). Separated proteins were transferred to PVDF membranes and were blocked using SuperBlockTMblocking buffer (Thermo Scientific, cat no.37515). Incubation with secondary antibody and 30 washing of the membrane were done in TBS supplemented with 0.1% Tween-20 (v / v) and 5% (w / v) non-fat dry milk. Incubation of the membranes with primary antibodies was performed in TBS supplemented with 0.1% Tween-20 (v / v), 5% (w / v) BSA and 0.01% sodium azide.

[0118] For re-blotting, membrane was stripped using Restore™ Western Blot Stripping

[0119] Buffer (Thermo, cat no.21059). The immunoblots were incubated overnight with primary antibodies against p-IRF3 Ser396 (Thermo Scientific, cat no MA5-14947), IRF3 (CST, cat no. 4302), IKKe (CST, cat no.3416), and TBK1 (CST, cat no.3013). anti-rabbit secondary antibody (Amersham Pharmacia, NA934V) was used to detect protein using chemiluminescence (Thermo 5 Scientific, cat no 34578 or Thermo Scientific cat no. 34095). Chemiluminescent signal on membranes was measured using Vilber FX system.

[0120] Biochemical serum analysis

[0121] Alanine aminotransferase (ALT) were measured in blood serum using a standard assay in a Cobas C111 biochemical analyzer (Roche, Mannheim, Germany). 10

[0122] Cell death assay

[0123] BMDMs were seeded in 96-well plate (3x105cells per well) one day before the treatment in the presence of 20ng / ml M-CSF (ImmunoTools, cat no.12343113).

[0124] Cells were treated with different concentrations of MRT67307 (Selleckchem, cat no. S7948) or BX795 (Medchemexpress, cat no. MCE-HY-10514) in combination with 10μM Nec1s 15 (Selleckchem, cat no. S8641) or 10μM GSK2982772 (Selleckchem, cat no. S8484) in the presence of 0.25 μM Diyo-1 (AAT Bioquest, cat no. 143413-85-8) and 20ng / ml M-CSF (ImmunoTools, cat no. 12343113). Cells were imaged for 24 hours using IncuCyte imaging system. Cell death was measured by the incorporation of Diyo-1 (AAT Bioquest, cat no.143413- 85-8) using Incucyte image analysis software. 20

[0125] Immunohistochemistry and histology

[0126] Heart samples from mice were fixed in 4 % PFA and embedded in paraffin. Sections of 5 µm were subjected to histological analysis by H&E staining and Masson’s Trichrome staining. For immunohistochemical analysis, slides were rehydrated and incubated with peroxidase blocking buffer (0.04 M NaCitrate, 0.121 M Na2HPO2, 0.03M NaN3, 3% H2O2) for 15 minutes. Slides 25 were washed and antigen-retrieval was performed by digestion with proteinase K (10 µg / ml) for 5 minutes in TEX-buffer (50 mM Tris, 1 mM EDTA, 0.5 % Triton X-100, pH 8.0) for CD45 staining or in citrate TRIS buffer (pH 6) in a pressure cooker for CD3 staining. Sections were blocked for 60 minutes and incubated with the primary antibody for CD45 (clone 30 F-11, eBioscience 14- 0451) or CD3 (clone CD3-12, Biorad MCA1477) at 4°C overnight. A biotinylated secondary anti- 30 rat antibody (Jackson Immuno Research, 112-065-003) was incubated on the sections for 60 minutes. Stainings were visualized using the ABC Vectastain Elite Kit (Vector Laboratories) and DAB substrate (Dako and Vector Laboratories). Sections were then counterstained with hematoxylin for staining of the nuclei, dehydrated and mounted with Entellan.

[0127] TUNEL staining

[0128] TUNEL stain was performed according to the protocol of the DeadEndTMFluorometric TUNEL Kit from Promega (G3250). In brief, sections were rehydrated and washed with 0.85 % NaCl solution and PBS. Tissue sections were then fixed in 4 % PFA for

[0129] 15 minutes and washed with PBS. Digestion with Proteinase K (20 µg / ml) was performed for 5 minutes and sections were washed with PBS. For TUNEL staining, sections were equilibrated with equilibration buffer (provided by the kit) and incubated with rTdT incubation buffer (provided by the kit) for 60 minutes at 37 °C covered with coverslips. The reaction was terminated by immersing the slides in 2x SSC buffer (provided by the kit) for 15 minutes. Sections were washed with PBS and mounted with Vectashield + DAPI (Vector Laboratories) to stain nuclei. Samples were analyzed under a fluorescence microscope.

[0130] The examples show:

[0131] To investigate the role of the kinase activity of TBK1 and IKK ^ in vivo the inventors used CRISPR / Cas9-mediated gene targeting to generate knock-in mice expressing kinase inactive TBK1 (TBK1D135N) (Figure 1A). This approach allows to study the specific function of the kinase activity of TBK1, thus simulating the effect of small molecules that inhibit its enzymatic activity without affecting any kinase-independent scaffold functions. Tbk1D135N / D135Nmice were embryonic lethal similarly to Tbk1- / -mice (Figure 1B), demonstrating that lack of TBK1 kinase activity, and not of any kinase-independent scaffold functions, causes embryonic lethality. The embryonic lethality of Tbk1D135N / D135Nmice was dependent on RIPK1 kinase activity, as crossing to Ripk1D138N / D138Nmice expressing kinase-inactive RIPK1 allowed the survival of Tbk1D135N / D135Nmice (Figure 1B). Tbk1D135N / D135N; Ripk1D138N / D138Nbut also Tbk1D135N / D135N; Ripk1D138N / WTmice reached adulthood without showing apparent pathology (Figure 1B and data not shown), demonstrating that even one RIPK1 kinase inactive allele was sufficient to rescue the embryonic lethality of Tbk1D135N / D135Nmice. These results demonstrated that genetic inhibition of TBK1 kinase activity leads to embryonic lethality in a RIPK1 kinase activity-dependent manner.

[0132] To study the role of the enzymatic activity of IKK ^ and to address its functional redundancy with TBK1 the inventors generated mice that express kinase inactive IKK ^ (IKKeK38A) (Figure 2A). IkkeK38A / K38Amice were viable and fertile and showed no apparent pathology, similarly to IKK ^- deficient mice (Hemmi et al., 2004; Tenoever et al., 2007). To assess possible functional redundancy between IKK ^ and TBK1, the inventors examined whether RIPK1 inhibition also prevents embryonic lethality in mice expressing kinase inactive versions of both IKK ^ and TBK1. The inventors found that Tbk1D135N / D135N; IkkeK38A / K38Amice also died during embryogenesis but were rescued by crossing to Ripk1D138N / D138Nmice (Figure 2B). Also heterozygous expression of kinase inactive RIPK1D138N was sufficient to rescue the embryonic lethality of these animals, with IkkeK38A / K38A; Tbk1D135N / D135N; Ripk1D138N / WTmice surviving to adulthood. However, IkkeK38A / K38A; Tbk1D135N / D135N; Ripk1D138N / WTmice developed neutrophilia and splenomegaly (Figure 3A-B), and showed liver damage as indicated by elevated ALT levels (Figure 4). Homozygous expression of kinase inactive RIPK1D138N conferred strong protection from splenomegaly and neutrophilia, with only a small fraction of Tbk1D135N / D135N; IkkeK38A / K38A; Ripk1D138N / D138Nmice showing mildly increased numbers of neutrophils and spleen size (Figure 3). Importantly IkkeK38A / K38A; Tbk1D135N / D135N; Ripk1D138N / D138Nmice did not show liver damage (Figure 4). Immunoblot analysis of bone marrow derived macrophages (BMDMs) from IkkeK38A / K38A; Tbk1D135N / D135N; Ripk1D138N / WTmice showed a complete lack of IRF3 phosphorylation in response to LPS stimulation, demonstrating that the introduced mutations fully inhibited TBK1 and IKK ^ kinase activity (Figure 5A). In addition, IkkeK38A / K38A; Tbk1D135N / D135N; Ripk1D138N / WTBMDMs did not produce IFN ^ in response to LPS stimulation, further confirming the full suppression of TBK1 / IKK ^-dependent interferon responses (Figure 5B). Therefore, inhibition of RIPK1 kinase activity rescued the embryonic lethality, suppressed splenomegaly and neutrophilia and prevented liver damage induced by the combined inhibition of the kinase activities of TBK1 and IKK ^.

[0133] To further investigate the mechanisms by which inhibition of TBK1 and IKK ^ cause neutrophilia in a RIPK1-kinase dependent manner, the inventors studied the role of TBK1 and IKK ^ in myeloid cells by employing a genetic mouse model allowing the inhibition of TBK1 kinase activity in myeloid cells. Specifically, the inventors generated mice containing one kinase inactive TBK1D135N allele with one loxP-flanked TBK1 allele (Tbk1FL / D135N) that were crossed with Cx3Cr1-Cre mice expressing Cre recombinase specifically in myeloid cells. Cre recombinase expression deletes the loxP-flanked Tbk1 allele resulting in the expression exclusively of the kinase inactive TBK1-D135N in myeloid cells (Figure 6). These Tbk1FL / D135NCx3Cr1-Cre mice did not develop neutrophilia or splenomegaly (Figure 7). To assess whether IKK ^ might compensate for the lack of TBK1 kinase activity, the inventors then generated IkkeK38A / K38ATbk1FL / D135NCx3Cr1- Cre, which lack IKK ^ kinase activity in all cells and in addition lack TBK1 kinase activity in myeloid cells. Analysis of these animals revealed that they developed prominent neutrophilia associated with splenomegaly (Figure 7). These results showed that the combined inhibition of IKK ^ and TBK1 in myeloid cells caused systemic pathology manifesting with neutrophilia and splenomegaly. This phenotype was reminiscent of the neutrophilia developing in mice with myeloid cell specific inhibition of IKK2 kinase activity (Ikk2FL / K44ACx3Cr1-Cre), which the inventors found is dependent on RIPK1 kinase activity as it is fully prevented by genetic inhibition of RIPK1 in Ikk2FL / K44ACx3Cr1-Cre Ripk1D138N / D138Nmice (WO2019 / 110832 incorporated herein by reference). The inventors therefore generated IkkeK38A / K38A; Tbk1FL / D135N; Cx3Cr1-Cre; Ripk1D138N / D138Nmice and found that inhibition of RIPK1 kinase activity prevented the development of splenomegaly and neutrophilia induced by the combined inhibition of TBK1 and IKK ^ in myeloid cells (Figure 7). Notably, heterozygous expression of kinase inactive RIPK1D138N had a partial effect considerably suppressing but not fully preventing splenomegaly and neutrophilia in IkkeK38A / K38ATbk1FL / D135N; Cx3Cr1-Cre; Ripk1WT / D138Nmice (Figure 7). Therefore, inhibition of RIPK1 kinase activity prevented the development of splenomegaly and neutrophilia caused by 5 combined inhibition of TBK1 and IKK ^ kinase activities. Moreover, the inventors found that pharmacological inhibition of TBK1 and IKK ^ kinase activity by treatment with MRT67307, a small molecule inhibitor of TBK1 and IKK ^ (Clark et al., 2011), caused cell death and the spontaneous release of IL-1 ^ and IL-1 ^ in BMDMs derived from wild type mice but not from Ripk1D138N / D138Nmice (Figure 8A, B). Pharmacological inhibition of RIPK1 using two highly specific RIPK1 kinase 10 inhibitors, namely Necrostatin-1s (Nec1s) and GSK2982772, also prevented IL-1 ^ release and cell death in BMDMs from wild type mice. In addition, treatment of wild type BMDMs with another TBK1 / IKK ^ inhibitor, BX795, also caused cell death and IL-1 ^ release that were fully prevented by pharmacological inhibition of RIPK1 with Nec1s or GSK2982772. Taken together, these results showed that inhibition of RIPK1 kinase activity prevents cell death, and IL-1 ^ and IL-1 ^ release 15 in BMDMs as well as the development of neutrophilia and splenomegaly in mice with myeloid cell specific inhibition of TBK1 and IKK ^ kinase activities.

[0134] The in vivo and in vitro findings showed that inhibition of RIPK1 kinase activity prevents embryonic lethality and supresses the development of neutrophilia, splenomegaly and liver damage in adult mice induced by combined inhibition of the kinase activities TBK1 and IKKε. 20 Based on these findings, the inventors envision that RIPK1 kinase inhibition will prevent the adverse effects caused by pharmacological inhibition of TBK1 / IKK ^, thus allowing the safe application of TBK1 / IKK ^ inhibitors for the treatment of human inflammatory and autoimmune diseases associated with elevated type I interferon signalling. To experimentally assess the applicability of combined inhibition of RIPK1 together with TBK1 / IKK ^ for the treatment of 25 diseases, the inventors performed a proof-of-concept study using Trex1-deficient mice as a mouse model of AGS, one of a group of diseases characterised as type I interferonopathies (Lee- Kirsch et al., . To investigate whether the combined inhibition of TBK1 and RIPK1 kinase activity can prevent the pathology induced by Trex1 deficiency, the inventors generated Trex1- / -; Tbk1D135N / D135N; Ripk1D138N / D138Nmice. Indeed, the inventors found that the combined genetic 30 inhibition of TBK1 and RIPK1 kinase activities, but not of RIPK1 kinase activity alone, strongly alleviated the development of pathology in Trex1- / -mice, as shown by strongly reduced infiltration of CD45+immune cells and particularly CD3+lymphocytes, reduced collagen deposition as well as reduced numbers of TUNEL+dying cells in the hearts of Trex1-deficient mice (Figure 9). Taken together, these results in a relevant mouse model of AGS provide experimental evidence 35 demonstrating that combined inhibition TBK1 and RIPK1 is well tolerated and effective for the therapy of type I interferonopathies.

[0135] In conclusion, this invention describes the combined application of RIPK1 inhibitors together with TBK1 / IKK ^ inhibitors for the treatment of human diseases associated with increased TBK1 / IKK ^-mediated responses such as type I interferon-associated diseases (e.g. example SLE and AGS), as well as metabolic diseases. The inventors provide evidence that RIPK1 inhibition 5 prevents the adverse effects caused by TBK1 / IKK ^ inhibition (neutrophilia, splenomegaly, liver damage), therefore RIPK1 inhibitors are predicted to allow the safe therapeutic application of TBK1 / IKK ^ inhibitors for the treatment of human diseases. In cases where both RIPK1-mediated cell death and inflammatory signalling and TBK1 / IKK ^-mediated responses contribute to disease pathogenesis, combination treatment with RIPK1 and TBK1 / IKK ^ inhibitors is expected to exhibit 10 synergistic therapeutic effects.

[0136] The inventors furthermore conducted cell culture experiments, which show that with increasing concentrations of TBK1 / IKKe inhibitor primary cells die / release IL-1B, which is prevented by RIPK1 kinase inhibition. Hence, the experiment shows that RIPK1 inhibitors can be used for extending the therapeutic window of TBK1 / IKKe inhibitors. 15

[0137] Combined inhibition of TBK1 and RIPK1 kinase activity prolongs survival of mice carrying Adar1 mutations, an enzyme that deaminates adenosine in RNA and thus prevents its recognition by MDA5, are found in patients with Aicardi–Goutières syndrome and mice lacking ADAR1 or its deaminase activity develop inflammatory pathologies. Particularly ADAR1 mutations mapping to the Zα domain combined with alleles resulting in loss of ADAR1 or specifically its p150 isoform 20 were shown to cause AGS and bilateral striatal necrosis (BSN) in human patients and severe MDA5-MAVS-mediated type I interferon-dependent pathology in mice. To model this condition, the inventors previously generated Adar1mZa / - mice and found that they developed a severe phenotype characterized by reduced body weight and early postnatal lethality. Messenger RNA expression analysis of lung, brain and spleen tissue of Adar1 mZa / - mice revealed increased 25 expression of several genes, the majority of which were linked to type I interferon responses. To assess whether combined inhibition of TBK1 and RIPK1 kinase activity could provide an effective approach for the treatment of this type I interferon-associated pathology the inventors crossed Adar1mZα / – mice with mice expressing kinase inactive TBK1-D135N and RIPK1-D138N resulting in Adar1mZα / –Tbk1D135N / D135N Ripk1D138N / D138N mice. The genetic inhibition of TBK1 and 30 RIPK1 kinase activities prolonged the survival of Adar1mZα / – mice, demonstrating that the inhibition of both TBK1 and RIPK1 kinase activities can be used effectively to treat a type I interferon-driven pathology caused by mutations in Adar1 (Figure 10).

[0138] Combined inhibition of TBK1 and RIPK1 kinase activity prevents the embryonic lethality of Dnase2a-deficient mice. Humans carrying mutations in Dnase2a, a lysosomal DNA degrading 35 enzyme, develop polyarthritis. Dnase2a-deficient mice display type I interferon receptor 1 (IFNAR1)-dependent embryonic lethality. However, with age mice lacking both Dnase2a and type I interferon receptor 1 (IFNAR1) develop polyarthritis that can be ameliorated by blocking TNF, IL1, or IL-6. Notably, the genetic abrogation of STING rescues the embryonic lethal and arthritis phenotype of Dnase2a-deficient mice, demonstrating that STING-induced inflammatory signaling drives these phenotypes in the absence of Dnase2a. A mutation, which disturbs the capacity of 5 STING to induce TNF production and TBK1 / IKKe-activation, can protect Dnase2a-deficient mice from both embryonic lethality and polyarthritis development. Dnase2a-deficient patient blood shows a specific genetic pattern related to blood disorders and an increased presence of developing red blood cells, indicating a potential unique impact of interferon on blood cell production. To assess whether combined inhibition of TBK1 and RIPK1 kinase activity could 10 provide an efficacious approach for treating the type I interferon-driven pathologies in these patients, the inventors crossed mice with mice lacking TBK1 and RIPK1 kinase activities resulting in Dnase2a- / - Tbk1D135N / D135N Ripk1D138N / D138N mice. Our data showed that the genetic inhibition of the kinase activities of both Tbk1 and Ripk1, but not Ripk1 alone, rescues the embryonic lethality of Dnase2a-deficient mice, indicating that the inhibition of both TBK1 and 15 RIPK1 kinase activities can effectively treat a pathology driven by type I interferon due to mutations in Dnase2a (Table A). Table A: The combined genetic inhibition of TBK1 and RIPK1 kinase activities rescue the embryonic lethality of Dnase2a-deficeint mice. Mendelian ratio of progeny from the intercross of Tbk1D135N / wtRipk1D138N / D138NDnase2a- / -mice is displayed. 20 REFERENCES
