Definitions
- the present invention falls within the therapeutic field, more specifically in the field of the treatment of hemophilia.
- the present invention relates to a compound of particular chemical structure, for its use for the treatment of haemophilia.
- Hemophilia is a rare genetic disease resulting in an impossibility for the blood to clot, and whose symptoms are spontaneous and repetitive post-traumatic bleeding in the joints and muscles. This bleeding can result in severe bleeding, the consequences of which can be particularly serious.
- hemophilia type A due to a deficiency of the coagulation factor FVIII, which is the most common type of hemophilia
- hemophilia type B due to a deficiency of the factor coagulation FIX.
- TFPI tissue Factor Pathway Inhibitor
- the alpha isoform contains an N-terminus of 22 residues, followed by three Kunitz domains (K1, K2, K3) and then a long negatively charged C-terminus.
- the beta isoform lacks a K3 domain and is terminated with a different C-terminus.
- the three-dimensional structure of each Kunitz domain is experimentally known.
- the K2 domain of TFPI binds to the active site of FXa and the K1 domain of TFPI binds to the active site of FVIIa, as described in particular in the publication by Girard et al., 1989, Nature 338(6215), 518-20.
- hemophilia is systematically treated by replacement therapies, consisting of intravenous injections, in the subject affected by the disease, of the missing factors FVIII or FIX. These treatments, in addition to their binding mode of administration, have the disadvantage of generating antibodies.
- New therapeutic strategies currently under development are based on the use of proteins which either increase coagulation, such as emicizumab, a bispecific monoclonal antibody, restoring coagulation equivalently to 10 to 20 IU/dL (10 to 20%) of factor VIII, but which can under certain conditions be responsible for thrombotic accidents, or block the main anticoagulants of the coagulation cascade, in particular TFPI.
- emicizumab a bispecific monoclonal antibody
- restoring coagulation equivalently to 10 to 20 IU/dL (10 to 20%) of factor VIII but which can under certain conditions be responsible for thrombotic accidents, or block the main anticoagulants of the coagulation cascade, in particular TFPI.
- Concizumab an anti-TFPI monoclonal antibody, has in particular been proposed as an inhibitor of TFPI.
- the present invention aims to provide a treatment for hemophilia not having in particular the disadvantages of antibody/protein-based treatments, this treatment making it possible to effectively restore coagulation in patients affected by the disease, preferably being administered by oral route.
- the present invention relates to a compound of formula (III') below, or one of its pharmaceutically acceptable salts, for its use, as an active agent, for the treatment of hemophilia in a subject suffering from by illness:

- Y 2 ' represents a covalent bond or an amide group
- a 2 ' represents an optionally substituted cyclic or heterocyclic group comprising two fused rings, at least one of said rings being aromatic.

- the subject treated according to the invention is in particular a mammal, for example a non-human mammal. It is preferably a human being.
- the compound used according to the invention advantageously makes it possible to restore coagulation, by restoring the generation of thrombin, in the plasma of a subject with haemophilia, type A as well as type B, including for subjects affected by severe forms of the disease.

- the compound used according to the invention does not present any toxicity for mammals. It can advantageously be administered orally, much more simply than the proteins used by the prior art, which must in turn be administered by injection.
- the compound according to the invention and its pharmaceutically acceptable salts, by their chemical nature and their low molecular weight, generally less than 5 kDa and even, for certain combinations of substituents, less than 1 kDa, or even less than 500 Da, are in particular much easier, and less expensive, to prepare than the protein/antibody compounds proposed by the prior art for the treatment of haemophilia.

In the case of a haemophilia A patient, the generation of thrombin is low or even almost zero for some patients.
- thrombin generation test makes it possible to globally evaluate the coagulation rate of a given plasma and in the present case, it makes it possible to evaluate the capacity of a molecule to restore or not restore coagulation in a hemophiliac patient.
- Hemophilia patient plasma was obtained from Cryopep (Montpellier, France).
- Adapalene is commercially available, in particular from Prestwick. It was dissolved in an 8% solution of dimethylsulfoxide (DMSO) then diluted to a concentration of 1 mM and then tested at the following concentrations: 50 mM, 5 mM, 0.5 mM (final concentrations in plasma).
- DMSO dimethylsulfoxide
- the thrombin generation test was performed at 37°C using a fully automated STA-Genesia analyzer (Diagnostica Stago) with STG®- Bleedscreen reagent (Diagnostica Stago) according to the manufacturer's instructions and according to the method established by Pr. Hemker in 2003.
- the STG®- Bleedscreen reagent is a mixture of tissue factor (TF) at low concentration with phospholipid vesicles (PL).
- the test is triggered by the addition of a mixture of calcium + fluorescent substrate (ZGGR-AMC) (STG®-FluoStart mixture).
- the plasma of a hemophiliac patient is spiked with the same buffer for diluting the compound, an 8% solution of dimethylsulfoxide (DMSO), as a negative control (0.4% of final DMSO ) in order to obtain the basal level of thrombin generation of the plasma used.
- DMSO dimethylsulfoxide
- the positive control is the same plasma spiked with plasma factor VIII (Factane, LFB, France) at a concentration of 1 IU/mL (or 100% factor VIII) in order to obtain the expected “normal” level of thrombin generation plasma used.
- the negative control (plasma from a hemophilia A patient overloaded with the dilution buffer) shows weak thrombin generation with a peak at 25 nM of thrombin and an ETP at 360 nM.min.
- the positive control (plasma from a hemophilia A patient spiked with 1 IU/mL of factor VIII) shows a “normal” generation of thrombin with a peak at 51 nM and an ETP at 599 nM.min.
- concentration of adapalene For the different concentrations of adapalene, an increase in the generation of thrombin is observed depending on the concentration of adapalene: the higher the concentration, the greater the generation of thrombin.
- adapalene already has an effect on increasing thrombin generation with a peak at 29.7 nM and an ETP at 455 nM.min.
- the increase in thrombin generation is greater with a peak at 39 nM and an ETP at 504 nM.min.
- adapalene restores thrombin generation to the same level as the positive control (100% FVIII) with a peak at 55 nM and an ETP at 588 nM.min.
- adapalene (Ad) at 50 mM makes it possible to obtain an increase in the generation of thrombin compared to the negative control, with a peak of thrombin generated and an ETP at the same level as the positive control.
- TFPI-K1 K2 truncated human TFPI
- Adapalene was tested for its ability to release FXa inhibition by TFPI-K1 K2 using a colorimetric assay in a 96-well plate format. All steps were performed at room temperature. FXa inhibition by increasing TFPI-K1 K2 concentrations was first analyzed to determine the best detection conditions. Concentrations of TFPI-K1 K2 and of FXa (New England Biolabs) of 30 nM and 0.5 nM respectively, were chosen to ensure complete inhibition of FXa, without a significant excess of TFPI-K1 K2. Each protein was diluted using the same buffer: 20 mM Hepes, 135 mM NaCl, 1% BSA, 2 mM CaCl 2 , pH 7.3. The test was performed manually in 96-well plates (Nunc Maxisorp®). The experiment was performed in duplicate at a final adapalene concentration of 50 mM.
- the plates were centrifuged to remove any bubbles and the optical density (OD) at 405 nm, corresponding to the hydrolysis of the PNAPEP-1025 substrate, was measured for 1 h at room temperature.
- Pd2(dba)2 (1.7 mg, 0.0016 mmol, 1 mol%) was added to a flame-dried reactor followed by SPHOS (2.6 mg, 0.0064 mmol, 4 mol%), 1 -(5-bromo-2-methoxyphenyl)adamantane (5) (50 mg, 0.16 mmol, 1 eq.), methyl 1,2,3,4-tetrahydroisoquinoline-6-carboxylate hydrochloride (6) (43 mg , 0.19 mmol, 1.2 eq.) and NaOfBu (36.5 mg, 0.38 mmol, 2.4 eq.). Anhydrous toluene (600mI, 267mM) was added and the reactor was sealed.
- ester (10) (30 mg, 0.07 mmol, 1eq.) in 4:1 THF:MeOH at room temperature was added 2M NaOH (105 ⁇ I, 0.21 mmol, 3 eq.) .
- the solution obtained was mixed for 16 h at 60°C.
- the reaction mixture was then poured into water and the aqueous phase was extracted with AcOEt.
- the resulting aqueous phase was acidified using 1 M HCl and extracted 3 times with AcOEt.
- the combined organic phases were dried over Na 2 SO 4 , filtered and concentrated in vacuo to obtain (HEMO-031) (17 mg, 59%) in the form of a white solid.
- ester (12) 15 mg, 0.035 mmol, 1eq.
- 2M NaOH 53 ⁇ l, 0.11 mmol, 3 eq.
- the solution obtained was stirred for 2 hours at 60°C.
- the reaction mixture was poured into water and the aqueous phase was extracted with AcOEt.
- the resulting aqueous phase was acidified with 1 M HCl and extracted 3 times with AcOEt.
- the combined organic phases were dried over Na2SO4, filtered and concentrated in vacuo to obtain (HEMO-032) (9mg, 62%) as a white solid.
- a second thrombin generation test is carried out, for compounds H27, H31, H32, H35, H38, H39 and compound H24.
- the thrombin generation test was carried out at 37°C using a CAT analyzer (Diagnostica Stago) with the PPP Reagent LOW reagent (Diagnostica Stago) in accordance with the manufacturer's instructions and according to the method established by Pr. Hemker in 2003.
- PPP Reagent LOW is a mixture of tissue factor (TF) 1pM with phospholipid vesicles (PL, 4mM).
- TF tissue factor
- PL, 4mM phospholipid vesicles
- ZGGR-AMC calcium + fluorescent substrate
- the plasma of a hemophiliac patient is spiked with the same buffer for diluting the compound, an 8% solution of dimethylsulfoxide (DMSO), as a negative control (0.4% of final DMSO ) in order to obtain the basal level of thrombin generation of the plasma used.
- DMSO dimethylsulfoxide
- the positive control is the same plasma spiked with plasma factor VIII (Factane, LFB, France) at a concentration of 1 IU/mL (or 100% factor VIII) in order to obtain the expected “normal” level of thrombin generation plasma used.
