Definitions

  • the present invention covers combinations of at least two components, component A and component B, comprising component A being an ATR kinase inhibitor, particularly Compound A, and component B being radium-223, particularly a pharmaceutically acceptable salt of radium-223.
  • component A being an ATR kinase inhibitor, particularly Compound A
  • component B being radium-223, particularly a pharmaceutically acceptable salt of radium-223.
  • Another aspect of the present invention covers the use of such combinations as described herein for the preparation of a medicament for the treatment or prophylaxis of a hyper - proliferative disease, particurlarly for the treatment of prostate cancer and/or bone metastases thereof.
  • Cancer is the second most prevalent cause of death in the United States, causing 450,000 deaths per year. While substantial progress has been made in identifying some of the likely environmental and hereditary causes of cancer, there is a need for additional therapeutic modalities that target cancer and related diseases. In particular there is a need for therapeutic methods for treating diseases associated with dysregulated growth / proliferation.
  • Cancer is a complex disease arising after a selection process for cells with acquired functional capabilities like enhanced survival / resistance towards apoptosis and a limitless proliferative potential. Thus, it is preferred to develop drugs for cancer therapy addressing distinct features of established tumors.
  • DDR DNA damage response
  • Proteins that directly recognize aberrant DNA structures such as the MRE11-Rad50-Nbsl complex recognizing DNA double strand breaks by binding to double-stranded DNA ends, or RPA (replication protein A) binding to single stranded DNA, recruit and activate the most upstream kinases of the DDR pathway, ATM (ataxia-telangiectasia mutated), ATR (ATM-and Rad3-related, UniProtKB/Swiss-Prot Q13535), and DNA-PKcs (DNA-dependent protein kinase).
  • ATM is primarily activated by DNA double strand breaks
  • DNA-PKcs is mainly involved in non-homologous end joining process of DNA repair
  • ATR responds to a broad spectrum of DNA damage, including double- strand breaks and lesions derived from interference with DNA replication.
  • Major components of downstream signaling of ATM include Chk2 and p53, whereas ATR signaling involves Chkl and cdc25.
  • Knockout of the ATR gene in mice is embryonically lethal and ATR knockout cells develop chromosome breaks and undergo apoptosis [E.J. Brown, D. Baltimore: ATR disruption leads to chromosomal fragmentation and early embryonic lethality. Genes Dev. 14, 397-402, 2000].
  • ATM is not essential for cell survival although ATM knockout cells are hypersensitive to ionizing radiation and agents which cause DNA double-strand breaks.
  • ATR which forms a complex with ATRIP (ATR-interacting protein, UniProtKB/Swiss-Prot Q8WXE1) is mainly activated by long stretches of single-stranded DNA which are generated by the continuing DNA unwinding activity of helicases upon stalled replication.
  • This replication stress with stalled replication forks may be induced by ultraviolet light, certain chemotherapeutic drugs, hydroxyurea, or aberrant oncogenic signaling resulting in increased replication initiation or origin firing.
  • Activation of ATR results in inhibition of the cell cycle in S or G2 phase via the Chkl-cdc25 pathway and in suppression of late origin firing.
  • the cell gains time to resolve the replication stress and, eventually, to restart replication after the source of stress has been removed.
  • As the ATR pathway ensures cell survival after replication stress it potentially contributes to resistance to chemotherapy. Thus inhibition of ATR kinase activity could be useful for cancer treatment.
  • oncogene-driven tumor cells e.g. Ras mutation/upregulation, Myc upregulation, CyclinE overexpression
  • ATR suppression in Ras oncogene driven cells was reported to result in substantial tumor cell killing [O. Gilad, BY Nabet, et al.: Combining ATR suppression with oncogenic Ras synergistically increases genomic instability, causing synthetic lethality or tumorigenesis in a dosage-dependent manner. Cancer Res. 70, 9693-9702, 2010].
  • a healthy normal cell which has ATM and ATR pathways in parallel, arrests in Gl phase of the cell cycle upon induced DNA damage even in presence of an ATR inhibitor.
  • a tumor cell which most often deficient in ATM and/or p53 signaling relies on the ATR pathway and undergoes cell death in presence of an ATR inhibitor. This suggests that ATR inhibitors may be used for the treatment of tumors with deficient ATM signaling and/or p53 function.
  • inhibitors of ATR kinase represent valuable compounds that should complement therapeutic options not only as single agents but also in combination with other drugs.
  • Radium-223 dichloride (Ra 223 Ci2) (Xofigo®) uses alpha radiation from radium-223 decay to kill cancer cells. It targets to bone tissue by virtue of its chemical similarity to calcium. It has an effect over a range of 2-10 cells and causes less damage to surrounding healthy tissues compared to current radiation therapy based on beta or gamma radiation. Significant increase in median overall survival was demonstrated in Phase III clinical trials and radium-223 dichloride (Xofigo) was approved as a treatment for castration-resistant prostate cancer (CRPC) patients with symptomatic bone metastases.
  • CRPC castration-resistant prostate cancer
  • a preferred suitable pharmaceutically acceptable salt of radium-223 is the dichloride (Ra 223 Cl2).
  • Radium-223 dichloride is a novel, targeted alpha-emitter that selectively binds to areas of increased bone turnover in bone metastases and emits high-energy alpha-particles of extremely short ( ⁇ 100 ⁇ ) range (Bruland O. S. et al., High-linear energy transfer irradiation targeted to skeletal metastases by the alpha-emitter 223 Ra: adjuvant or alternative to conventional modalities?, Clin. Cancer Res. 2006; 12: 6250s-7s). It is the first targeted alpha-emitter approved for the treatment of prostate cancer with bone metastases.
  • radium-223 is bound into newly formed bone stroma, especially within the microenvironment of osteoblastic or sclerotic metastases (Henriksen G. et al., Significant antitumor effect from bone-seeking, alpha-particle-emitting (223)Ra demonstrated in an experimental skeletal metastases model, Cancer Res. 2002; 62: 3120-3125; Henriksen G. et al., Targeting of osseous sites with alpha-emitting 223Ra: comparison with the beta-emitter 89Sr in mice, J. Nucl. Med 2003; 44: 252-59).
  • the high-energy alpha-particle radiation induces mainly double-strand DNA breaks resulting in a potent and highly localized cytotoxic effect in the target areas containing metastatic cancer cells
  • Lewington V.J. Bone- seeking radionuclides for therapy, J. Nucl. Med 2005; 46 (suppl 1): 38S-47S; Liepe K., Alpharadin, a 223 Ra-based alpha-particle-emitting pharmaceutical for the treatment of bone metastases in patients with cancer, Curr. Opin. Investig. Drugs 2009; 10: 1346-58; McDevitt M.R. et al., Radioimmunotherapy with alpha- emitting nuclides, Eur. J. Nucl. Med.
  • the short path length of the alpha-particles also means that toxicity to adjacent healthy tissue and particularly the bone marrow may be reduced (Kerr C, (223)Ra targets skeletal metastases and spares normal tissue, Lancet Oncol. 2002; 3: 453; Li Y., Russell P.J., Allen B.J., Targeted alpha-therapy for control of micrometastatic prostate cancer, Expert Rev. Anticancer Ther. 2004; 4: 459-68).
  • Radium-223 has demonstrated a favorable safety profile with minimal myelotoxicity in phase 1 and 2 studies of patients with bone metastases (Nilsson S. et al., First clinical experience with alpha-emitting radium-223 in the treatment of skeletal metastases, Clin. Cancer Res. 2005; 11 : 4451-59; Nilsson S. et al., Bone-targeted radium-223 in symptomatic, hormone-refractory prostate cancer: a randomised, multicentre, placebo-controlled phase II study, Lancet Oncol. 2007; 8: 587-94).
  • radium-223 reduces pain, improves disease-related biomarkers (e.g., bone alkaline phosphatase [ALP] and prostate-specific antigen [PSA]), and have suggested a survival benefit in patients with CRPC and bone metastases (Parker C. et al., A randomized, double-blind, dose-finding, multicenter, phase 2 study of radium chloride (Ra-223) in patients with bone metastases and castration-resistant prostate cancer, Eur Urol. 2013 Feb; 63(2): 189-97; Nilsson S.
  • ALP bone alkaline phosphatase
  • PSA prostate-specific antigen
  • the ALSYMPCA (ALpharadin in SYMptomatic Prostate CAncer patients) trial provides proof of principle for the role of targeted alpha-emitters in oncology.
  • radium-223 significantly prolonged overall survival with a 30.5% reduction in risk of death compared with placebo in patients with CRPC (Castration Resistant Prostate Cancer) and bone metastases.
  • Median survival with radium-223 was longer than placebo by 2.8 months.
  • All main secondary efficacy endpoints were statistically significant and favored treatment with radium-223, including the clinically defined endpoint of time to first skeletal-related event, which was significantly prolonged in patients receiving radium-223 (C. Parker et al., Alpha Emitter Radium-223 and Survival in Metastatic Prostate Cancer , The New England Journal of Medicine 369(3):213-23).
  • radium-223 inhibits osseous prostate cancer growth by dual targeting of cancer cells and bone microenvironment in mouse models.
  • a substantial percentage of cancer patients is affected by skeletal metastases.
  • As many as 85% of patients with advanced lung, prostate and breast carcinoma develop bony metastases (Garret R., Semin. Oncol. 72, 3433 -3435 (1993) Bone destruction in cancer; Nielsen, OS, Munro AJ, Tannock IF. J Clin Oncol 9, 509-5 24 (1991)).
  • Established treatments such as hormone therapy, chemotherapy and external radiotherapy often causes temporary responses, but ultimately most bone cancer patients experience relapses (Kanis JA.
  • 223 Ra is used as an a-emitting radiopharmaceutical for targeting of calcified tissues, e.g. bone surfaces and osseous tumor lesions. It can be suitable as a bone seeking radiopharmaceutical. It thus may be used for prophylactic cancer treatment by delivering a focused dose to bone surfaces in patients with a high probability of having undetected micro metastases at bone surfaces. Another example of its potential use would be in the treatment of painful osseous sites.

  • the alkaline-earth radionuclide radium-223 is suitable for the use of the nuclide as a cationic species and/or associated to a chelator or another form of a carrier molecule with affinity for calcified tissues.

Description

COMBINATION of ATR KINASE INHIBITORS WITH RADIUM-223 SALT
The present invention covers combinations of at least two components, component A and component B, comprising component A being an ATR kinase inhibitor, particularly Compound A, and component B being radium-223, particularly a pharmaceutically acceptable salt of radium-223. Another aspect of the present invention covers the use of such combinations as described herein for the preparation of a medicament for the treatment or prophylaxis of a hyper - proliferative disease, particurlarly for the treatment of prostate cancer and/or bone metastases thereof.
BACKGROUND
Cancer is the second most prevalent cause of death in the United States, causing 450,000 deaths per year. While substantial progress has been made in identifying some of the likely environmental and hereditary causes of cancer, there is a need for additional therapeutic modalities that target cancer and related diseases. In particular there is a need for therapeutic methods for treating diseases associated with dysregulated growth / proliferation.
Cancer is a complex disease arising after a selection process for cells with acquired functional capabilities like enhanced survival / resistance towards apoptosis and a limitless proliferative potential. Thus, it is preferred to develop drugs for cancer therapy addressing distinct features of established tumors.
The integrity of the genome of eukaryotic cells is secured by complex signaling pathways, referred to as the DNA damage response (DDR), and multiple DNA repair mechanisms. Upon recognizing DNA damage activation of the DDR pathways results in cell cycle arrest, suppression of general translation, induction of DNA repair, and, finally, in cell survival or cell death. Proteins that directly recognize aberrant DNA structures, such as the MRE11-Rad50-Nbsl complex recognizing DNA double strand breaks by binding to double-stranded DNA ends, or RPA (replication protein A) binding to single stranded DNA, recruit and activate the most upstream kinases of the DDR pathway, ATM (ataxia-telangiectasia mutated), ATR (ATM-and Rad3-related, UniProtKB/Swiss-Prot Q13535), and DNA-PKcs (DNA-dependent protein kinase). Whereas ATM is primarily activated by DNA double strand breaks, and DNA-PKcs is mainly involved in non-homologous end joining process of DNA repair, ATR responds to a broad spectrum of DNA damage, including double- strand breaks and lesions derived from interference with DNA replication. Major components of downstream signaling of ATM include Chk2 and p53, whereas ATR signaling involves Chkl and cdc25. Knockout of the ATR gene in mice is embryonically lethal and ATR knockout cells develop chromosome breaks and undergo apoptosis [E.J. Brown, D. Baltimore: ATR disruption leads to chromosomal fragmentation and early embryonic lethality. Genes Dev. 14, 397-402, 2000]. In contrast, ATM is not essential for cell survival although ATM knockout cells are hypersensitive to ionizing radiation and agents which cause DNA double-strand breaks.
ATR, which forms a complex with ATRIP (ATR-interacting protein, UniProtKB/Swiss-Prot Q8WXE1) is mainly activated by long stretches of single-stranded DNA which are generated by the continuing DNA unwinding activity of helicases upon stalled replication. This replication stress with stalled replication forks may be induced by ultraviolet light, certain chemotherapeutic drugs, hydroxyurea, or aberrant oncogenic signaling resulting in increased replication initiation or origin firing. Activation of ATR results in inhibition of the cell cycle in S or G2 phase via the Chkl-cdc25 pathway and in suppression of late origin firing. The cell gains time to resolve the replication stress and, eventually, to restart replication after the source of stress has been removed. As the ATR pathway ensures cell survival after replication stress it potentially contributes to resistance to chemotherapy. Thus inhibition of ATR kinase activity could be useful for cancer treatment.
In oncogene-driven tumor cells (e.g. Ras mutation/upregulation, Myc upregulation, CyclinE overexpression) increased replication stress has been observed as compared to healthy normal cells. ATR suppression in Ras oncogene driven cells was reported to result in substantial tumor cell killing [O. Gilad, BY Nabet, et al.: Combining ATR suppression with oncogenic Ras synergistically increases genomic instability, causing synthetic lethality or tumorigenesis in a dosage-dependent manner. Cancer Res. 70, 9693-9702, 2010].
Although ATM and ATR are principally activated by different types of DNA damage their signaling includes some cross-talk thus that they can, at least partially, substitute for each others function. This finding suggests some tumor-cell selectivity of pharmaceutical inhibition of ATR.
A healthy normal cell, which has ATM and ATR pathways in parallel, arrests in Gl phase of the cell cycle upon induced DNA damage even in presence of an ATR inhibitor. In contrast, a tumor cell which most often deficient in ATM and/or p53 signaling relies on the ATR pathway and undergoes cell death in presence of an ATR inhibitor. This suggests that ATR inhibitors may be used for the treatment of tumors with deficient ATM signaling and/or p53 function.
Details of DDR signaling and the functional role of ATM and ATR were recently reviewed in:
E. Fokas, R. Prevo et al.: Targeting ATR in DNA damage response and cancer therapeutics.
Cancer Treatment Rev 40, 109-117, 2014. J.M. Wagner & S.H. Kaufmann: Prospects for the use of ATR inhibitors to treat cancer. Pharmaceuticals 3, 1311-1334, 2010. D. Woods & J.J. Tuchi:
Chemotherapy induced DNA damage response. Cancer Biol. Thera. 14, 379-389, 2013. A. Marechal & L. Zou: DNA damage sensing by the ATM and ATR kinases. Cold Spring Harb. Perspect. Biol. 5, a012716, 2013. M.K. Zeman & K.A. Cimprich: Causes and consequences of replication stress. Nat. Cell Biol. 16, 2-9, 2014. S. Llona-Minguez, A. Hoglund et al.: Chemical strategies for development of ATR inhibitors. Exp. Rev. Mol. Med. 16, elO, 2014.
Thus inhibitors of ATR kinase represent valuable compounds that should complement therapeutic options not only as single agents but also in combination with other drugs.
Radium-223 dichloride (Ra223Ci2) (Xofigo®) uses alpha radiation from radium-223 decay to kill cancer cells. It targets to bone tissue by virtue of its chemical similarity to calcium. It has an effect over a range of 2-10 cells and causes less damage to surrounding healthy tissues compared to current radiation therapy based on beta or gamma radiation. Significant increase in median overall survival was demonstrated in Phase III clinical trials and radium-223 dichloride (Xofigo) was approved as a treatment for castration-resistant prostate cancer (CRPC) patients with symptomatic bone metastases.
A preferred suitable pharmaceutically acceptable salt of radium-223 is the dichloride (Ra223Cl2). Radium-223 dichloride is a novel, targeted alpha-emitter that selectively binds to areas of increased bone turnover in bone metastases and emits high-energy alpha-particles of extremely short (<100 μιη) range (Bruland O. S. et al., High-linear energy transfer irradiation targeted to skeletal metastases by the alpha-emitter 223Ra: adjuvant or alternative to conventional modalities?, Clin. Cancer Res. 2006; 12: 6250s-7s). It is the first targeted alpha-emitter approved for the treatment of prostate cancer with bone metastases.
As a bone-seeking calcium mimetic, radium-223 is bound into newly formed bone stroma, especially within the microenvironment of osteoblastic or sclerotic metastases (Henriksen G. et al., Significant antitumor effect from bone-seeking, alpha-particle-emitting (223)Ra demonstrated in an experimental skeletal metastases model, Cancer Res. 2002; 62: 3120-3125; Henriksen G. et al., Targeting of osseous sites with alpha-emitting 223Ra: comparison with the beta-emitter 89Sr in mice, J. Nucl. Med 2003; 44: 252-59). The high-energy alpha-particle radiation induces mainly double-strand DNA breaks resulting in a potent and highly localized cytotoxic effect in the target areas containing metastatic cancer cells (Lewington V.J., Bone- seeking radionuclides for therapy, J. Nucl. Med 2005; 46 (suppl 1): 38S-47S; Liepe K., Alpharadin, a 223Ra-based alpha-particle-emitting pharmaceutical for the treatment of bone metastases in patients with cancer, Curr. Opin. Investig. Drugs 2009; 10: 1346-58; McDevitt M.R. et al., Radioimmunotherapy with alpha- emitting nuclides, Eur. J. Nucl. Med. 1998; 25: 1341-51). The short path length of the alpha-particles also means that toxicity to adjacent healthy tissue and particularly the bone marrow may be reduced (Kerr C, (223)Ra targets skeletal metastases and spares normal tissue, Lancet Oncol. 2002; 3: 453; Li Y., Russell P.J., Allen B.J., Targeted alpha-therapy for control of micrometastatic prostate cancer, Expert Rev. Anticancer Ther. 2004; 4: 459-68).
Radium-223 has demonstrated a favorable safety profile with minimal myelotoxicity in phase 1 and 2 studies of patients with bone metastases (Nilsson S. et al., First clinical experience with alpha-emitting radium-223 in the treatment of skeletal metastases, Clin. Cancer Res. 2005; 11 : 4451-59; Nilsson S. et al., Bone-targeted radium-223 in symptomatic, hormone-refractory prostate cancer: a randomised, multicentre, placebo-controlled phase II study, Lancet Oncol. 2007; 8: 587-94).
Phase 2 studies have shown that radium-223 reduces pain, improves disease-related biomarkers (e.g., bone alkaline phosphatase [ALP] and prostate-specific antigen [PSA]), and have suggested a survival benefit in patients with CRPC and bone metastases (Parker C. et al., A randomized, double-blind, dose-finding, multicenter, phase 2 study of radium chloride (Ra-223) in patients with bone metastases and castration-resistant prostate cancer, Eur Urol. 2013 Feb; 63(2): 189-97; Nilsson S. et al., A randomized, dose -response, multicenter phase II study of radium-223 chloride for the palliation of painful bone metastases in patients with castration-resistant prostate cancer, Eur. J. Cancer 2012; 48: 678-86).
The ALSYMPCA (ALpharadin in SYMptomatic Prostate CAncer patients) trial provides proof of principle for the role of targeted alpha-emitters in oncology. In this trial, radium-223 significantly prolonged overall survival with a 30.5% reduction in risk of death compared with placebo in patients with CRPC (Castration Resistant Prostate Cancer) and bone metastases. Median survival with radium-223 was longer than placebo by 2.8 months. All main secondary efficacy endpoints were statistically significant and favored treatment with radium-223, including the clinically defined endpoint of time to first skeletal-related event, which was significantly prolonged in patients receiving radium-223 (C. Parker et al., Alpha Emitter Radium-223 and Survival in Metastatic Prostate Cancer , The New England Journal of Medicine 369(3):213-23).
According to Suominen et al. (Clin Cancer Res. 2017 Aug l;23(15):4335-4346) radium-223 inhibits osseous prostate cancer growth by dual targeting of cancer cells and bone microenvironment in mouse models. A substantial percentage of cancer patients is affected by skeletal metastases. As many as 85% of patients with advanced lung, prostate and breast carcinoma develop bony metastases (Garret R., Semin. Oncol. 72, 3433 -3435 (1993) Bone destruction in cancer; Nielsen, OS, Munro AJ, Tannock IF. J Clin Oncol 9, 509-5 24 (1991)). Established treatments such as hormone therapy, chemotherapy and external radiotherapy often causes temporary responses, but ultimately most bone cancer patients experience relapses (Kanis JA. Bone 17,101s-105s (1995), Bone and cancer. Pathophysiology and treatment of metastases). There is thus a strong need for new therapies to relieve pain and slow down tumor progression. 223Ra is used as an a-emitting radiopharmaceutical for targeting of calcified tissues, e.g. bone surfaces and osseous tumor lesions. It can be suitable as a bone seeking radiopharmaceutical. It thus may be used for prophylactic cancer treatment by delivering a focused dose to bone surfaces in patients with a high probability of having undetected micro metastases at bone surfaces. Another example of its potential use would be in the treatment of painful osseous sites.
The alkaline-earth radionuclide radium-223 is useful for the targeting of calcified tissues, e.g., bone and a pharmaceutical acceptable solution comprising 223Ra.
The alkaline-earth radionuclide radium-223 is suitable for the use of the nuclide as a cationic species and/or associated to a chelator or another form of a carrier molecule with affinity for calcified tissues. Thus may be combined with a chelator that can be subsequently conjugated to a molecule with affinity for calcified tissues. The effect of the radioisotope to generated by providing a cascade of a-particles on bone surfaces and/or in calcified tumors for the palliation of pain caused by various diseases and/or for the prophylactic use against possible minimal disease to the skeleton, and/or also for the therapeutic treatment of established cancer to the bone. The diseases where the radioisotopes could be used includes, but are not limited to skeletal metastases of prostate-, breast-, kidney- and lung cancer as well as primary bone cancer and also multiple myeloma.
However, the state of the art does not disclose the combinations of the present invention comprising an inhibitor of ATR kinase or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable salt of the alkaline-earth radionuclide radium-223. SUMMARY OF THE INVENTION

The term "substituted" means that one or more hydrogens on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valency under the existing circumstances is not exceeded, and that the substitution results in a stable compound. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.
The term "optionally substituted" means optional substitution with the specified groups, radicals or moieties. Ring system substituent means a substituent attached to an aromatic or nonaromatic ring system which, for example, replaces an available hydrogen on the ring system.
By "stable compound' or "stable structure" is meant a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.
As used herein, the term "one or more", e.g. in the definition of the substituents of the compounds of the general formulae of the present invention, is understood as meaning "one, two, three, four or five, particularly one, two, three or four, more particularly one, two or three, even more particularly one or two".
The invention also includes all suitable isotopic variations of the compound of component A, particularly of Compound A. An isotopic variation of the compound of component A is defined as one in which at least one atom is replaced by an atom having the same atomic number but an atomic mass different from the atomic mass usually or predominantly found in nature. Examples of isotopes that can be incorporated into the compound of component A include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulphur, fluorine, chlorine, bromine and iodine, such as 2H (deuterium), 3H (tritium), UC, 13C, 14C, 15N, 170, 180, 32P, 33P, 33S, 34S, 35S, 36S, 18F,
CI, Br, I, I, I and I, respectively. Certain isotopic variations of the compound of component A, for example, those in which one or more radioactive isotopes such as 3H or 14C are incorporated, are useful in drug and/or substrate tissue distribution studies. Tritiated and carbon- 14, i.e., 14C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements and hence may be preferred in some circumstances. Isotopic variations of the compound of component A can generally be prepared by conventional procedures known by a person skilled in the art such as by the illustrative methods or by the preparations described in the examples hereafter using appropriate isotopic variations of suitable reagents.
Where the plural form of the word compounds, salts, polymorphs, hydrates, solvates and the like, is used herein, this is taken to mean also a single compound, salt, polymorph, isomer, hydrate, solvate or the like.
The compounds of component A may contain one or more asymmetric centre, depending upon the location and nature of the various substituents desired. Asymmetric carbon atoms may be present in the (R) or (S) configuration, resulting in racemic mixtures in the case of a single asymmetric centre, and diastereomeric mixtures in the case of multiple asymmetric centres. In certain instances, asymmetry may also be present due to restricted rotation about a given bond, for example, the central bond adjoining two substituted aromatic rings of the specified compounds.
The compounds of component A may contain sulphur atoms which are asymmetric, such as an as mmetric sulphoxide or sulphoximine group, of structure:
Figure imgf000014_0001
, for example, in which * indicates atoms to which the rest of the molecule can be bound.
Substituents on a ring may also be present in either cis or trans form. It is intended that all such configurations (including enantiomers and diastereomers), are included within the scope of the present invention. Preferred compounds of component A are those which produce the more desirable biological activity, particularly preferred is Compound A. Separated, pure or partially purified isomers and stereoisomers or racemic or diastereomeric mixtures of the compounds of component A are also included within the scope of the present invention. The purification and the separation of such materials can be accomplished by standard techniques known in the art.
The optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, for example, by the formation of diastereoisomeric salts using an optically active acid or base or formation of covalent diastereomers. Examples of appropriate acids are tartaric, diacetyltartaric, ditoluoyltartaric and camphorsulfonic acid. Mixtures of diastereoisomers can be separated into their individual diastereomers on the basis of their physical and/or chemical differences by methods known in the art, for example, by chromatography or fractional crystallisation. The optically active bases or acids are then liberated from the separated diastereomeric salts. A different process for separation of optical isomers involves the use of chiral chromatography (e.g., chiral HPLC columns), with or without conventional derivatisation, optimally chosen to maximise the separation of the enantiomers. Suitable chiral HPLC columns are manufactured by Daicel, e.g., Chiracel OD and Chiracel OJ among many others, all routinely selectable. Enzymatic separations, with or without derivatisation, are also useful. The optically active compounds of this invention can likewise be obtained by chiral syntheses utilizing optically active starting materials.
In order to limit different types of isomers from each other reference is made to IUPAC Rules Section E (Pure Appl Chem 45, 11-30, 1976).
The present invention includes all possible stereoisomers of the compounds of component A as single stereoisomers, or as any mixture of said stereoisomers, e.g. R- or S- isomers, or E- or Z- isomers, in any ratio. Isolation of a single stereoisomer, e.g. a single enantiomer or a single diastereomer, of a compound of component A may be achieved by any suitable state of the art method, such as chromatography, especially chiral chromatography, for example. Further, the compounds of component A, particularly of Compound A, may exist as tautomers. For example, any compound of component A which contains a pyrazole moiety as a heteroaryl group for example can exist as a 1H tautomer, or a 2H tautomer, or even a mixture in any amount of the two tautomers, or a triazole moiety for example can exist as a 1H tautomer, a 2H tautomer, or a 4H tautomer, or even a mixture in any amount of said 1H, 2H and 4H tautomers, namely:

The amount of polar solvents, in particular water, may exist in a stoichiometric or non- stoichiometric ratio. In the case of stoichiometric solvates, e.g. a hydrate, hemi-, (semi-), mono-, sesqui-, di-, tri-, terra-, penta- etc. solvates or hydrates, respectively, are possible. The present combination includes all such hydrates or solvates.
Further, the compounds of the present combination can exist in free form, e.g. as a free base, or as a free acid, or as a zwitterion, or can exist in the form of a salt. Said salt may be any salt, either an organic or inorganic addition salt, particularly any pharmaceutically acceptable organic or inorganic addition salt, customarily used in pharmacy.
The present invention includes all possible salts of the components of the present combination as single salts, or as any mixture of said salts, in any ratio.
Furthermore, the present invention includes all possible crystalline forms, or polymorphs, of the compounds of components of the present combination, either as single polymorphs, or as a mixture of more than one polymorphs, in any ratio.
When radicals in the compounds of the present combination are substituted, the radicals may be mono- or polysubstituted, unless specified otherwise. In the context of the present invention, all radicals which occur more than once are defined independently of one another. Substitution by one, two or three identical or different substituents is preferred.

The synthesis of Compound A is described in Example 111 of WO2016020320 (Al).
The term "pharmaceutically acceptable salt" of component A, particularly of Compound A, refers to a relatively non-toxic, inorganic or organic acid addition salt of a compound of the present invention. For example, see S. M. Berge, et al. "Pharmaceutical Salts," /. Pharm. Sci. 1911 , 66, 1-19. Pharmaceutically acceptable salts include those obtained by reacting the main compound, functioning as a base, with an inorganic or organic acid to form a salt, for example, salts of hydrochloric acid, sulfuric acid, phosphoric acid, methane sulfonic acid, camphor sulfonic acid, oxalic acid, maleic acid, succinic acid and citric acid. Pharmaceutically acceptable salts also include those in which the main compound functions as an acid and is reacted with an appropriate base to form, e.g., sodium, potassium, calcium, magnesium, ammonium, and chorine salts. Those skilled in the art will further recognize that acid addition salts of the claimed compounds may be prepared by reaction of the compounds with the appropriate inorganic or organic acid via any of a number of known methods. Alternatively, alkali and alkaline earth metal salts of acidic compounds of the invention are prepared by reacting the compounds of the invention with the appropriate base via a variety of known methods. Representative salts of a component A of this invention include the conventional non-toxic salts and the quaternary ammonium salts which are formed, for example, from inorganic or organic acids or bases by means well known in the art. For example, such acid addition salts include acetate, adipate, alginate, ascorbate, aspartate, benzoate, benzenesulfonate, bisulfate, butyrate, citrate, camphorate, camphorsulfonate, cinnamate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, fumarate, glucoheptanoate, glycerophosphate, hemisulfate, heptanoate, hexanoate, chloride, bromide, iodide, 2-hydroxyethanesulfonate, itaconate, lactate, maleate, mandelate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oxalate, pamoate, pectinate, persulfate, 3-phenylpropionate, picrate, pivalate, propionate, succinate, sulfonate, sulfate, tartrate, thiocyanate, tosylate, and undecanoate.
Base salts include alkali metal salts such as potassium and sodium salts, alkaline earth metal salts such as calcium and magnesium salts, and ammonium salts with organic bases such as dicyclohexylamine and N-methyl-D-glucamine. Additionally, basic nitrogen containing groups may be quaternized with such agents as lower alkyl halides such as methyl, ethyl, propyl, or butyl chlorides, bromides and iodides; dialkyl sulfates like dimethyl, diethyl, dibutyl sulfate, or diamyl sulfates, long chain halides such as decyl, lauryl, myristyl and strearyl chlorides, bromides and iodides, aralkyl halides like benzyl and phenethyl bromides and others.
Said component A may be in the form of a pharmaceutical formulation which is ready for use to be administered simultaneously, concurrently, separately or sequentially with component B and optionally component C as further described infra. The components A and B and optionally C may be administered independently of one another by the oral, intravenous, topical, local installations, intraperitoneal or nasal route. The specific compounds of the lists as disclosed above are preferred as being component A of the combination, most preferred is "Compound A" used in the Experimental Section. It is to be understood that the present invention relates also to any combination of the embodiments of component A described above.
COMPONENT B OF THE COMBINATION
Component B is a pharmaceutically acceptable salt of the alkaline-earth radionuclide radium- 223. A pharmaceutically acceptable salt of radium-223 can be, for example, an acid addition salt with an inorganic acid, such as hydrochloric, hydrobromic, hydroiodic, sulfuric, bisulfuric, phosphoric, or nitric acid, for example, or with an organic acid, such as formic, acetic, acetoacetic, pyruvic, trifluoroacetic, propionic, butyric, hexanoic, heptanoic, undecanoic, lauric, benzoic, salicylic, 2 (4 hydroxybenzoyl) benzoic, camphoric, cinnamic, cyclopentanepropionic, digluconic, 3 hydroxy 2 naphthoic, nicotinic, pamoic, pectinic, persulfuric, 3 phenylpropionic, picric, pivalic, 2 hydroxyethanesulfonate, itaconic, sulfamic, trifluoromethanesulfonic, dodecylsulfuric, ethansulfonic, benzenesulfonic, para toluenesulfonic, methansulfonic, 2 naphthalenesulfonic, naphthalinedisulfonic, camphorsulfonic acid, citric, tartaric, stearic, lactic, oxalic, malonic, succinic, malic, adipic, alginic, maleic, fumaric, D gluconic, mandelic, ascorbic, glucoheptanoic, glycerophosphoric, aspartic, sulfosalicylic, hemisulfuric, or thiocyanic acid, for example.
A preferred pharmaceutically acceptable salt of radium-223 is the dichloride (223RaCl2). Methods for preparation of a pharmaceutically acceptable solution comprising radium-223 are disclosed e.g. in WO 2000/40275(A2), WO 2011/134671(A1), and WO 2011/134672(A1).
Pharmaceutically acceptable solutions comprising radium-223 show a unique mechanism of action as a targeted radiopharmaceutical. They represent a new generation of alpha emitting therapeutic pharmaceuticals based on the natural bone-seeking nuclide radium-223. Preferably, an aqueous solution of radium-223 chloride (223R3Cl2) for intravenous injection, sterile and free from bacterial endotoxins is used.
Preferably, the solution is isotonic, containing a sodium citrate buffered saline to physiological pH. A preferred dosage regimen for radium-223 chloride injection is 50 kBq per kg body weight given at 4 week intervals, as a course consisting of 6 injections. Single radium-223 doses up to 250 kBq per kg body weight were evaluated in a phase I clinical trial. The observed adverse reactions at this dose were diarrhea and reversible myelosuppression (including one case (1/5) of grade 3 neutropenia).
As an example, the aqueous radium-223 dichloride solution may be supplied in a single-dose 10 ml vial which contains a fill volume of 6 ml. This product has a radioactivity concentration of radium-223 of 1,000 kBq/mL (0.03 mCi/mL), corresponding to 0.53 ng/mL of radium at reference date. The active moiety is the alpha particle emitting nuclide radium-223 (half-life is 11.4 days), present as a divalent cation (223Ra2+). The fraction of energy emitted from radium- 223 and its daughters as alpha-particles is 95.3%, the fraction emitted as beta-particles is 3.6%, and the fraction emitted as gamma-radiation is 1.1%. The combined energy from the emitted radiation from complete decay of radium-223 and its daughter nuclides is 28.2 MeV.
Radium-223 is to be administered intravenously by qualified personnel as a slow bolus injection. An intravenous access line should be used for administration of Radium-223. The line must be flushed with isotonic saline before and after injection of Radium-223. Radium-223 selectively targets areas of increased bone turnover, as in bone metastases, and concentrates by forming a complex with hydroxyapatite. Alpha emission contributes about 93% of the total radiation absorbed dose. The high linear energy alpha particle radiation induces double-strand DNA breaks, resulting in a potent and localized cytotoxic effect in the target areas containing metastatic cancer cells. The short path length (less than 100 micrometers) of the alpha particles minimizes the effect on adjacent healthy tissue such as the bone marrow.

They provide the active ingredient in admixture with a dispersing or wetting agent, a suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, for example those sweetening, flavoring and coloring agents described above, may also be present. Components of this invention can also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil such as liquid paraffin or a mixture of vegetable oils.

Illustrative of oils which can be used in the parenteral formulations of this invention are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, sesame oil, cottonseed oil, corn oil, olive oil, petrolatum and mineral oil. Suitable fatty acids include oleic acid, stearic acid, isostearic acid and myristic acid. Suitable fatty acid esters are, for example, ethyl oleate and isopropyl myristate. Suitable soaps include fatty acid alkali metal, ammonium, and triethanolamine salts and suitable detergents include cationic detergents, for example dimethyl dialkyl ammonium halides, alkyl pyridinium halides, and alkylamine acetates; anionic detergents, for example, alkyl, aryl, and olefin sulfonates, alkyl, olefin, ether, and monoglyceride sulfates, and sulfosuccinates; non-ionic detergents, for example, fatty amine oxides, fatty acid alkanolamides, and poly(oxyethylene-oxypropylene)s or ethylene oxide or propylene oxide copolymers; and amphoteric detergents, for example, alkyl-beta- aminopropionates, and 2-alkylimidazoline quarternary ammonium salts, as well as mixtures.
The parenteral compositions of this invention will typically contain from about 0.5% to about 25% by weight of the active ingredient in solution. Preservatives and buffers may also be used advantageously. In order to minimize or eliminate irritation at the site of injection, such compositions may contain a non-ionic surfactant having a hydrophile-lipophile balance (HLB) preferably of from about 12 to about 17. The quantity of surfactant in such formulation preferably ranges from about 5% to about 15% by weight. The surfactant can be a single component having the above HLB or can be a mixture of two or more components having the desired HLB.
Illustrative of surfactants used in parenteral formulations are the class of polyethylene sorbitan fatty acid esters, for example, sorbitan monooleate and the high molecular weight adducts of ethylene oxide with a hydrophobic base, formed by the condensation of propylene oxide with propylene glycol.
The pharmaceutical compositions of the present invention can be in the form of sterile injectable aqueous suspensions. Such suspensions may be formulated according to known methods using suitable dispersing or wetting agents and suspending agents such as, for example, sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethyl-cellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents which may be a naturally occurring phosphatide such as lecithin, a condensation product of an alkylene oxide with a fatty acid, for example, polyoxyethylene stearate, a condensation product of ethylene oxide with a long chain aliphatic alcohol, for example, heptadeca-ethyleneoxycetanol, a condensation product of ethylene oxide with a partial ester derived form a fatty acid and a hexitol such as polyoxyethylene sorbitol monooleate, or a condensation product of an ethylene oxide with a partial ester derived from a fatty acid and a hexitol anhydride, for example polyoxyethylene sorbitan monooleate. The sterile injectable preparation can also be a sterile injectable solution or suspension in a nontoxic parenterally acceptable diluent or solvent. Diluents and solvents that may be employed are, for example, water, Ringer's solution, isotonic sodium chloride solutions and isotonic glucose solutions. In addition, sterile fixed oils are conventionally employed as solvents or suspending media. For this purpose, any bland, fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid can be used in the preparation of injectables.
Components of the invention can also be administered in the form of suppositories for rectal administration of the drug. These components can be prepared by mixing the drug with a suitable non-irritation excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials are, for example, cocoa butter and polyethylene glycol.
Another formulation employed in the methods of the present invention employs transdermal delivery devices ("patches"). Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds of the present invention in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art (see, e.g., US Patent No. 5,023,252, issued June 11, 1991, incorporated herein by reference). Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.
Controlled release formulations for parenteral administration include liposomal, polymeric microsphere and polymeric gel formulations that are known in the art.
It can be desirable or necessary to introduce a component of the present invention to the patient via a mechanical delivery device. The construction and use of mechanical delivery devices for the delivery of pharmaceutical agents is well known in the art. Direct techniques for, for example, administering a drug directly to the brain usually involve placement of a drug delivery catheter into the patient's ventricular system to bypass the blood-brain barrier. One such implantable delivery system, used for the transport of agents to specific anatomical regions of the body, is described in US Patent No. 5,011,472, issued April 30, 1991.

Combinations of the present invention might also be used for treating diseases associated with excessive and/or abnormal angiogenesis.
Inappropriate and ectopic expression of angiogenesis can be deleterious to an organism. A number of pathological conditions are associated with the growth of extraneous blood vessels. These include, e.g., diabetic retinopathy, ischemic retinal-vein occlusion, and retinopathy of prematurity [Aiello et al. New Engl. J. Med. 1994, 331, 1480 ; Peer et al. Lab. Invest. 1995, 72, 638], age-related macular degeneration [AMD ; see, Lopez et al. Invest. Opththalmol. Vis. Sci. 1996, 37, 855], neovascular glaucoma, psoriasis, retrolental fibroplasias, angiofibroma, inflammation, rheumatoid arthritis (RA), restenosis, in-stent restenosis, vascular graft restenosis, etc. In addition, the increased blood supply associated with cancerous and neoplastic tissue, encourages growth, leading to rapid tumor enlargement and metastases. Moreover, the growth of new blood and lymph vessels in a tumor provides an escape route for renegade cells, encouraging metastases and the consequence spread of the cancer. Thus, combinations of the present invention can be utilized to treat and/or prevent any of the aforementioned angiogenesis diseases, e.g., by inhibiting and/or reducing blood vessel formation ; by inhibiting, blocking, reducing, decreasing, etc. endothelial cell proliferation or other types involved in angiogenesis, as well as causing cell death or apoptosis of such cell types.
DOSE AND ADMINISTRATION
Component A
Based upon standard laboratory techniques known to evaluate compounds useful for the treatment of hyper-proliferative diseases and angiogenic diseases, by standard toxicity tests and by standard pharmacological assays for the determination of treatment of the conditions identified above in mammals, and by comparison of these results with the results of known medicaments that are used to treat these conditions, the effective dosage of the compounds of this invention can readily be determined for treatment of each desired indication. The amount of the active ingredients to be administered in the treatment of one of these conditions can vary widely according to such considerations as the particular component and dosage unit employed, the mode of administration, the period of treatment, the age and sex of the patient treated, and the nature and extent of the condition treated. The total amount of the active ingredients to be administered will generally range from about 0.001 mg/kg to about 200 mg/kg body weight per day, and preferably from about 0.01 mg/kg to about 50 mg/kg body weight per day. Clinically useful dosing schedules of a compound will range from one to three times a day dosing to once every four weeks dosing. In addition, "drug holidays" in which a patient is not dosed with a drug for a certain period of time, may be beneficial to the overall balance between pharmacological effect and tolerability. A unit dosage may contain from about 0.5 mg to about 1500 mg of active ingredient, and can be administered one or more times per day or less than once a day. The average daily dosage for administration by injection, including intravenous, intramuscular, subcutaneous and parenteral injections, and use of infusion techniques will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily rectal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily vaginal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily topical dosage regimen will preferably be from 0.1 to 200 mg administered between one to four times daily. The transdermal concentration will preferably be that required to maintain a daily dose of from 0.01 to 200 mg/kg. The average daily inhalation dosage regimen will preferably be from 0.01 to 100 mg/kg of total body weight.
Component B
A preferred dosage regimen for radium-223 injection is 50 kBq per kg body weight given at 4 week intervals, as a course consisting of 6 injections. Single radium-223 doses up to 250 kBq per kg body weight were evaluated in a phase I clinical trial. The observed adverse reactions at this dose were diarrhea and reversible myelosuppression (including one case (1/5) of grade 3 neutropenia).
As an example, the aqueous radium-223 dichloride solution may be supplied in a single-dose 10 ml vial which contains a fill volume of 6 ml. This product has a radioactivity concentration of radium-223 of 1,000 kBq/mL (0.03 mCi/mL), corresponding to 0.53 ng/mL of radium at reference date.
Radium-223 is to be administered intravenously by qualified personnel as a slow bolus injection. An intravenous access line should be used for administration of radium-223. The line must be flushed with isotonic saline before and after injection of radium-223.
Of course the specific initial and continuing dosage regimen for each patient will vary according to the nature and severity of the condition as determined by the attending diagnostician, the activity of the specific compounds employed, the age and general condition of the patient, time of administration, route of administration, rate of excretion of the drug, drug combinations, and the like. The desired mode of treatment and number of doses of a compound of the present invention or a pharmaceutically acceptable salt or ester or composition thereof can be ascertained by those skilled in the art using conventional treatment tests.

Compound A
Component B :
In this Experimental Section and in the Figures, component B is radium-223 dichloride, the synthesis of which is disclosed in WO2000/040275, which is incorporated herein in its entirety by reference.
Test system/ In vivo Model (applied in Experiments 1, 2 and 3):
The efficacy of Compound A in combination with radium-223 dichloride (Ra-223) was studied in the osteoblastic and mixed prostate cancer bone metastases model LNCaP-luc in male NOD/Scid mice (Minhong Zou et al., ONCOLOGY REPORTS 30: 615-622, 2013; Multiple metastases in a novel LNCaP model of human prostate cancer). LNCaP is an androgen-receptor (AR) positive CRPC cell line with several mutations/deletions in DNA damage or mismatch repair genes (APCR2714C, ARIDlAfs, ATG5fs, ATMA1119V/K1572N, ATRXEE2264- 2265E, BRCA2fs, CHEK2T430N, ERCC3A740T;R391W, ERCC5L1023I,

LNCaP cells secrete prostate specific antigen (PSA) and are known to form osteoblastic and mixed lesions when inoculated to bone marrow cavity. Therefore this model can be effectively used for testing the effects of cancer drug candidates on the growth of prostate cancer cells in bone. In this experiment a luciferase transfected LNCaP cell line (LNCaP-luc) has been used to allow additional tumor growth monitoring by Bioluminescent Imaging (BLI) (Ruxana T. Sadikot and Timothy S. Blackwell; Proc Am Thorac Soc Vol 2. pp 537-540, 2005; Bioluminescence Imaging).
Mice were 5-8 weeks of age at the beginning of the study. On day 0 mice were given intratibial inoculation of LNCaP-luc human prostate cancer cells. The development of osteoblastic lesions were monitored by X-ray imaging before dosing was started and in 3 weeks intervals thereafter. The lesion area in hind limbs was determined from the images with MetaMorph image analysis software (Molecular Devices LLC, Sunnyvale, CA, USA) by drawing the outlines of radio- opaque and -lucent areas. Tumor burden was quantified by imaging the bioluminescence emitted by the LNCaP-luc cells. The obtained data were analyzed using Living Image® software (PerkinElmer, Waltham, MA, USA) version 4.2. Average radiance (p/s/cm2/sr) was determined from the inoculated tibia. Blood samples were taken every second week and the animals radiographed every three weeks, starting from week four. On week five, animals were stratified to treatment groups (n = 10-20) according to the BLI signal, PSA and radiography, and dosing was started. Body weights were determined twice a week. Changes in the body weight were a measure of treatment-related toxicity (> 10% = critical, stoppage in treatment until recovery, > 20% = toxic, termination). The animals were sacrificed six or seven weeks after dosing was started. PSA and N-terminal procollagen type I (PINP) were measured in plasma as markers of tumor growth and bone formation. PSA was measured using Human PSA ELISA assay (R&D Systems) (Hsing AW, Chokkalingam AP. Prostate cancer epidemiology. Front Biosci.

BJU Int. 2001;88:811-7), the levels of PINP were determined using VICTOR2 Multilabel Counter (PerkinElmer, Waltham, MA, USA) (N. Koopmans et al., THE JOURNAL OF UROLOGY, Vol. 178, 849-853, September 2007. Serum Bone Turnover Markers (PINP and ICTP) for the Early Detection of Bone Metastases in Patients With Prostate Cancer: A Longitudinal Approach; Windy Dean-Colomb et al.; Breast Cancer Res Treat. 2013 January ; 137(2). Elevated serum PINP predicts development of bone metastasis and survival in early-stage breast cancer). Statistical analysis was effected using single-factor ANOVA and comparison with the control group by means of pair-by-pair comparative analysis (Dunnett's test) or student's t-test.
Experiment 1:
The following experimental groups were assessed:
1) Vehicle for Ra-223: 28 mmol/L sodium citrate, 5 ml/kg, iv (=intraveneous) every 4 weeks (q4w)
2) Ra-223: 300 kBq/kg, 5 ml/kg, iv, q4w
3) Compound A dose 1 : 20 mg/kg 2 days on/ 5 days off po (= peroral) once per day (qd) + Vehicle for Ra-223,28 mmol/L sodium citrate, 5 ml/kg, iv, q4w
4) Compound A dose 2: 50 mg/kg 2 days on/ 5 days off po qd+ Vehicle for Ra-223, 28 mmol/L sodium citrate, 5 ml/kg, iv, q4w
5) Combo Ra-223 + Compound A dose 1: Ra-223 (300 kBq/kg, 5 ml/kg, iv, q4W, + Compound A (20 mg/kg 2 days on/ 5 days off po qd, started on week 4 after tumor cell inoculation) 6) Combo Ra-223 + Compound A dose 2: Ra-223 (300 kBq/kg, 5 ml/kg, iv, q4W, started on week 4 after tumor cell inoculation) + Compound A (50 mg/kg 2 days on/ 5 days off po qd, started on week 4 after tumor cell inoculation)
Results of Experiment 1:
Tumor growth in vehicle treated control group resulted in an increase of PSA level in plasma, increase of the BLI signal in bone and an enlarged bone lesion area. However, BLI analysis revealed high variation in the vehicle treated control group, whereby this parameter has been excluded in the final study analysis. Ra-223 single agent decreased PINP level in plasma compared to vehicle treated control group. Compound A treatment alone had no significant effect on tumor burden as analyzed by PSA or PINP. Combination therapies were significantly (P < 0.05) more effective in decreasing PSA (see Figure 1 A) and PINP (see Figure 1 B) level in plasma than vehicle, Ra-223 alone or the respective test dose of Compound A alone. The treatments were well tolerated, no critical body weight loss >10% was recorded (see Figure 2). In summary, our data indicate synergistic effects of the ATR inhibitor Compound A and radium- 223 in inhibiting tumor growth in the prostate cancer bone metastases model LNCaP-luc, indicating a strong potential as a future treatment of CRPC patients with bone metastases. To evaluate the cooperativity of the combination of Compound A with radium-223 dichloride expected additivity was calculated according to the Bliss model (C=A+B-A*B; wherein C is the expected T/C of the combination of drug A and drug B if they act additive, A is T/C of drug A, B is T/C of drug B). Excess >10% over the expected additive effect is assumed to indicate synergism of the two drugs, less than 10% of the expected additive effect is assumed to indicate antagonism (Bliss, C.I., The toxicity of poisons applied jointly. Ann. Appl. Biol. 26, 585-615, 1939) (see Table 1):

Experiment 2:
To evaluate different dosing schedules of Compound A in Ra-223 combination treatment the following experimental groups were assessed in Experiment 2:
1) Vehicle for Ra-223: 28 mmol/L sodium citrate, 5 ml/kg, iv (= intraveneous) every 4 weeks (q4w)
2) Ra-223: 150 kBq/kg, 5 ml/kg, iv, q4w

Tumor growth in vehicle treated control group resulted in an increase of PSA level in plasma, increase of the BLI signal in bone and an enlarged bone lesion area. Ra-223 or Compound A single agent treatments had no significant effect on tumor burden as analysed by PSA level in plasma, BLI signal and total bone lesion area in comparison to vehicle treated control group. Combination therapies were significantly (P < 0.05) more effective in decreasing PSA level in plasma compared to vehicle control when Compound A was applied in weekly cycles for 2 days on and 5 days off starting concurrently with Ra-223 or 24h or 48h after Ra-223 (see Figure 3 A). Total bone lesion area was significantly reduced in combination therapy compared to vehicle control when Compound A was applied in weekly cycles for 2 days on and 5 days off starting concurrently with Ra-223 or 24h after Ra-223 (see Figure 3 B). Tumor burden determined by BLI signal in bone was significantly reduced by all tested combination treatment schedules in comparison to vehicle control (see Figure 3 C). Overall, treatments were well tolerated. No treatment related critical body weight loss (> 10%) or toxicities/death were recorded (data not shown).
In summary, our data indicate that, based on tumor burden (PSA, BLI) and bone lesions, Compound A treatment starting 24h after the first Ra-223 dose and applied in continued weekly cycles, achieves best anti-tumor activity in Ra-223 combination treatment in the prostate cancer bone metastases model LNCaP-luc. However, Compound A treatment starting concurrently or 48h after the first Ra-223 dose and applied in continued weekly cycles, as well as Compound A treatment starting 24h after each Ra-223 dose, applied in 4 weekly cycles, also show inhibitory effects in LNCaP-luc bone tumor growth in combination treatment with Ra-223.

Experiment 3:
To evaluate different doses of Compound A in Ra-223 combination treatment the following experimental groups were assessed in Experiment 3:
1) Vehicle for Ra-223: 28 mmol/L sodium citrate, 5 ml/kg, iv (= intraveneous) every 4 weeks (q4w)
2) Ra-223: 150 kBq/kg, 5 ml/kg, iv, q4w
3) Compound A: 20 mg/kg 2 days on/ 5 days off po (= peroral) once per day (qd)
4) Combo Ra-223 (150 kBq/kg, 5 ml/kg, iv, q4w) + Compound A (5 mg/kg 2 days on/ 5 days off po, qd, start 24 hours after Ra-223)
5) Combo Ra-223 (150 kBq/kg, 5 ml/kg, iv, q4w) + Compound A (10 mg/kg 2 days on/ 5 days off po, qd, start 24 hours after Ra-223) 6) Combo Ra-223 (150 kBq kg, 5 ml/kg, iv, q4w) + Compound A (20 mg kg 2 days on/ 5 days off po, qd, start 24 hours after Ra-223)
7) Combo Ra-223 (150 kBq/kg, 5 ml/kg, iv, q4w) + Compound A (40 mg/kg 1 day on/ 6 days off po, qd, start 24 hours after Ra-223)
Results of Experiment 3:
Tumor growth in vehicle treated control group resulted in an increase of PSA level in plasma, increase of the BLI signal in bone and an enlarged bone lesion area. Ra-223 or Compound A single agent treatments had no significant effect on tumor burden as analysed by PSA level in plasma, BLI signal and total bone lesion area compared to vehicle treated control group, evaluation of bone growth marker PINP in plasma revealed reduction by Ra-223 alone compared to vehicle treated control. All tested Compound A doses evaluated in combination with Ra-223 achieved significant (P < 0.05) decrease in serum PSA or PINP level, BLI signal and bone lesion area compared to vehicle control group (see Table 3, Figure 4 A-D), except Ra-223 + Compound A 5 mg/kg achieving no significance with regards to PSA (see Figure 4 A). Overall, treatments were well tolerated. No treatment related critical body weight loss (> 10%) or toxicities/death were recorded (data not shown).
In summary, our data indicate that, based on tumor burden (PSA, BLI), bone growth (PINP) and bone lesions, Compound A doses higher than 5 mg/kg applied once daily for 2 days on and 5 days off starting 24h after the first Ra-223 dose and given in continued weekly cycles, demonstrate anti-tumor activity of the combination treatment in the prostate cancer bone metastases model LNCaP-luc and improve efficacy of respective monotherapies. Overall, best anti-tumor activity, at good tolerability, was achieved with Compound A doses of 20 mg/kg once daily for 2 days on and 5 days off or 40 mg/kg once daily for 1 day on and 6 days off starting 24h after the first Ra-223 dose and given in continued weekly cycles.
