Abstract

Composition for the treatment of diseases associated with lysosomal disorders. Pharmaceutical composition comprising a pharmacological chaperone (CF) and Coenzyme Q10 (CoQ) and its use for the treatment of a disease caused by mutations in the GBA1 gene, particularly for the treatment of Gaucher disease.

Description

The present invention relates to a pharmaceutical composition comprising a pharmacological chaperone (CF) and coenzyme 0 10 (CoO). Likewise, the present invention relates to the method of preparing said composition and its use for the treatment of a lysosomal storage disease associated with the

10 mutation of lysosomal acid ~ -glucocerebrosidase (GBA1 gene), particularly for the treatment of Gaucher disease, and more particularly for the treatment of Gaucher disease with neuropathic phenotype (Gaucher disease type II or type 111).

15 STATE OF THE TECHNIQUE

Smooth storage disorders describe a heterogeneous group of rare inherited diseases with loss of function of lysosomal enzymes. As a result, an abnormal metabolism of several substrates is generated that is not

20 gradually degrade and accumulate in lysosomes, affecting their function and that of other organelles such as mitochondria, autophagic imbalance and inflammation, and which results in phenotypes that include visceromegaly, neurological pathologies, skeletal injuries and premature death.

25 Currently, some of these pathologies only have symptomatic therapies that follow two therapeutic strategies: substrate reduction therapy (TRS), which inhibits the enzymes involved in the production of the substrate that accumulates, and enzyme replacement therapy (TER) , which exogenously administers the active recombinant enzyme that is found to be defective.

Gaucher's disease is the most predominant lysosomal storage disorder. It is caused by mutations in the GBA1 gene that result in a defective enzyme ~ -glucocerebrosidase or insufficient activity. Many of these mutations lead to significant defects in the folding of protein 35 during translation in the endoplasmic reticulum (ER), resulting in a reduction in the transport of the enzyme to the lysosome (degradation mediated by the

cellular quality control machinery). The decrease in its catalytic activity causes the accumulation of glucosylceramide and glucosyl sphingolipids in macrophage lysosomes and visceral organs. Gaucher's disease is subdivided into 3 types based on age that begins to manifest the disease and the involvement of the central nervous system (CNS). Gaucher patients without CNS manifestations are classified as type 1, more common; while those patients with neurological manifestations are classified in types 11 and III (Grabowski, G.A., Gaucher disease: gene frequencies and genotype / phenotype correlations. Genet Test,

1997. 1 (1): p. 5-12)

10 For lysosomal disorder of Gaucher's disease, TER is a high economic cost and is not very effective for cases that show involvement of the central nervous system since recombinant enzymes do not cross the blood brain barrier. Thus, there is a large number of patients for whom there is no treatment or its effectiveness is very low.

The TRS drugs have greater potential to penetrate the CNS and produce benefits at the neuronal level. This is the case of N-butyl-1-deoxynojirimycin (NBDNJ, Miglustat, Zavesca®), which acts as a weak glucosylceramide inhibitor

20 synthase, reducing the biosynthesis of glucosylceramide. Miglustat has been approved only for use in Gaucher type 1 patients, of mild to moderate severity, but not for patients of type 11 and 111. In addition, many patients treated with Miglustat have experienced side effects that include diarrhea, loss of weight and tremors.

25 Some inhibitors of glycosidases enzymes involved in lysosomal storage diseases are able to bind to the active site and stabilize the appropriate folding, being able to act as "pharmacological chaperones» (CF) that facilitate the transport of the catalytically active form to lysosomes. Of this

Thus, the development of compounds with pharmacological chaperone activity has been postulated as a possible therapeutic strategy for the treatment of lysosomal storage diseases, of particular interest for those clinical manifestations of the disease that involve the central nervous system. For this, it is essential that increases in the activity of the enzyme are achieved

35 mutated, at the origin of the disease, sufficiently high, which can hardly be achieved with the use of pharmacological chaperones alone.

One of the most prevalent mutations in Gaucher's disease is the L444P variant, which results in an incorrect folding in the ER and failures in its transport to the lysosome. Homozygous patients for the L444P mutation have severe neurological forms of the disease. The mutation is a 1448T> C 5 base change in the GBA1 gene that results in the substitution of the amino acid lysine for proline at position 444 in the polypeptide chain, located in one of the non-catalytic domains of the enzyme glucocerebrosidase (GBA) . This mutation is especially refractory to the available treatments, including TCF, so there is an urgent need to develop therapeutic strategies that are useful, in particular, in patients with this genotype. Recently, it has been reported that b2-cyclic spino iminoazúres derived from L-idonojirimycin behave as CFs in human Gaucher fibroblasts homozygous for the L444P mutation, increasing glucocerebrosidase activity and lysosome enzyme traffic. One of the most promising candidates within this family of CFs is the N- [N '- (4

15 adamantan-1-ylcarboxamidobutyl) thiocarbamoyl] -1,6-anhydro-L-donoji rimycin (NAd 8TAlJ) (Alfonso, P., et al., Bicyclic derivatives of L-idonojirimycin as pharmacoJogicaJ chaperones for neuronopathic forms of Gaucher disease. Chembiochem, 2013. 14 (8): p.943-9).

20 A lower production cost, the possibility of oral administration and the ability to cross the blood brain barrier are advantages of this therapy for Gaucher's disease, especially for types II and 111.

Despite its potential, research in pharmacological chaperone therapy

25 (TCF) has not yet led to new drugs. This ultimate objective would be greatly facilitated by the development of strategies that enhance the action of pharmacological chaperones, for example by co-formulation with other active compounds.

30 There is therefore a need to identify molecules that allow correcting or improving the pathologies associated with lysosomal storage diseases, particularly Gaucher disease, and acting in synergy with pharmacological chaperones, so that formulations containing both components produce a superior therapeutic benefit.

DESCRIPTION OF THE INVENTION

In the present invention it is described that the combination of a pharmacological chaperone and coenzyme 0 10 (CoO) produces a benefit in patient cells

5 of Gaucher greater than the sum of those that would produce the individual treatments, representing an improved therapeutic option for the treatment of the disease of Gaucher, especially for the neuropathic types of it.

Thus, one aspect of the present invention relates to a pharmaceutical composition 10 comprising a pharmacological chaperone (CF) and Coenzyme 0 10 (Coa).

Throughout the present invention, the term "pharmacological chaperone" refers to a compound capable of binding to the human p-glucocerebrosidase enzyme, which is mutated and is dysfunctional in patients suffering from 15 Gaucher disease, and driving to an increase in your medically relevant activity. As examples of pharmacological chaperones currently under study, iminoazúres derivatives such as 1-deoxinojirimycin, isofagomine, iminoazúres sp2 derivatives such as NAdB-AIJ and other compounds not related to iminoazúres such as trans-4- (2) -amino-3,5

Dibromobenzylamino) cyclohexanol (ambroxol).

Coenzyme 0 10, also known as ubiquinone, ubidecarenone or coenzyme Q, is a 1,4-benzoquinone that can exist in three redox states: fully oxidized (ubiquinone), semiquinone (ubisemiquinone), and totally reduced (ubiquinol). In the following, the term coenzyme 0 10 (Coa) refers to any of these redox forms or states. CoO is an antioxidant and energy transporter considered as a potential treatment for neurodegenerative diseases, such as Parkinson's disease (Ebadi, M., et aL, Ubiquinone (coenzyme q10) and mitochondria in oxidative stress of parkinson's disease.

EXAMPLES

The invention will now be illustrated by tests carried out by the inventors, which show the effectiveness of the product of the invention.

Example 1. Effect of the combined CoQ and NAdBT-AIJ treatment, in relative 1: 1 molar ratio, in vitro in Gaucher cells with the l444P variant in homozygosis on mitochondrial dysfunction.

Cultures of control dermal fibroblasts and patients with disease

20 Gaucher carriers of the L444P mutation were analyzed to check the status and functioning of the mitochondrial network.

First, a 20% reduction in mitochondrial respiratory chain activity was observed, specifically in the 11 + 111 complex, associated with a

25 secondary deficiency in Coenzyme QlO levels. As a consequence of these anomalies, it was confirmed that the mitochondrial membrane potential (6lVm) is decreased in Gaucher fibroblasts with a high proportion of depolarized mitochondria isolated from the tubular mitochondrial network (Figure 1A and 1B) observed by immunofluorescence microscopy after staining with MitoTracker net. The essays

Flow cytometry, using this same marker (Figure 1C), allows quantifying the reduction of mitochondrial membrane potential. The fibroblasts were cultured in the absence and presence of CoQ (25IJM), CF NAdBT-AIJ (25IJM) or CoQ + CF in relative 1: 1 mole ratio (25IJM + 25IJM) for 96 h. The mitochondrial membrane potential was recovered by individual treatments but from

35 more significantly with the combined treatment.

The energy production levels in the form of ATP are also reduced due to the reduction of mitochondrial membrane potential and the treatments also managed to increase them proportionally to the increase in mitochondrial potential.

The association of mitochondrial dysfunction with an increase in the production of reactive oxygen species (ROS) is well demonstrated. Figure 1D depicts the measures of mitochondrial oxidative stress in fibroblasts obtained by flow cytometry assays using the MitoSOX Red marker. Production

10 mitochondrial superoxide is increased 1.5 times confirmed oxidative stress in Gaucher fibroblasts. Supplementation with coa, NAdBT-AIJ or a combination of both in a 1: 1 relative mole ratio induces a considerable reduction of these levels.

Example 2. Effect of the CoQ and NAdBT-AIJ combined treatment, in relative 1: 1 molar ratio, in vitro in Gaucher cells with L444P variant in homozygosis on autophagic stress.

There is a relationship between high levels of oxidative stress and activation of autophagy.

20 To determine whether autophagy is increased in Gaucher L444P fibroblasts, the amount of acid vacuoles was quantified by staining with LysoTracker and fluorescence microscopy and flow cytometry assays. Using this technique, a 1.4-fold increase in LysoTracker staining was observed in Gaucher fibroblasts compared to control fibroblasts (Figure 2A).

25 The number of lysosomes in the cultures was quantified to elucidate whether autophagy in these fibroblasts decreases as a result of an improvement in mitochondrial function by CoQ supplementation and / or mutant glucocerebrosidase folding by treatment with NAdBT-AIJ chaperones. Figure 2A indicates that the

30 lysosomal activity is reduced by individual treatment but more significantly by the combination of both.

Analysis by polyacrylamide gel electrophoresis with dodecyl sulfate (SDSPAGE) -Western blot suggests an increase in autophagic markers such as Atg1235 5, beclin1 and LC3B in pathological fibroblasts versus controls. This autophagy was found to be selective of the mitochondria, observing the presence of

Colocalization "punctatas" in immunofluorescence assays of autophagic markers (LC3B) with mitochondrial markers (cytochrome c) Figure 2B. LC3B staining was difficult to detect in control fibroblasts. In Gaucher fibroblasts the population of small round mitochondria shows a high

5 colocalization of cytochrome c and LC3B (r = O.8929), while mitochondria tubular no (r = 0.0526).

Supplementation with coa (25 IJM) or CF NAdBT-AIJ (25 IJM) partially reduced the number of "punctatas" LC3 / Cytochrome C. However, the combination of both 10 treatments in 1: 1 relative mola ratio was highly effective and drastically reduced these elements.

Example 3. Effect of the CoQ and NAdBT -AIJ combined treatment, in 1: 1 relative molar ratio, in vitro in Gaucher cells with the L444P variant in

15 homozygosis on the enzymatic activity glucocerebrosidase and its correct traffic to the lysosomes. Glucocerebrosidase activity in the fibroblasts of patients is reduced to levels below 10% compared to control cell values. Figure 3A shows how enzymatic activity is partially restored after

20 improvement of mitochondrial function by CoQ (1.2 times) as well as by the correct folding induced by treatment with NAdBT-AIJ chaperones (2.4 times). The combined treatment of both compounds in a 1: 1 relative mole ratio achieves a greater improvement in activity levels (3.4 times).

25 Deficiencies in enzymatic activity are associated with reduced levels of protein expression which, as with activity, are recovered with coa and CF treatment. The protein expression levels determined by Western blot are shown in Figure 3B. The expression of o-tubulin is used as load control. A densitometric analysis of the

30 Western blot result.

Example 4. Effect of the combined CoQ and NAdBT -AIJ treatment on glucocerebrosidase traffic_ The natural traffic of the glucocerebrosidase enzyme to the lysosome is also

35 reestablished after co-treatment of coa and CF, as shown in Figure 4. It shows a fluorescence microscopy assay with antibodies against lysosomal LAMP-1 protein and glucocerebrosidase. The colocalization of both proteins confirms the presence of the enzyme in ellisosome. Fibroblasts that were ca-treated with CoQ and CF NAdBT-AIJ in relative 1: 1 mole ratio have a glucocerebrosidase staining profile with greater intensity and colocalization

5 with the lysosomal LAMP-1 protein. In turn, the signal of the glucocerebrosidase that lays with the POI protein of the endoplasmic reticulum decreases, suggesting that the protein is transported correctly to the Golgi apparatus and to the lysosomes.

10 Example 5. Effect of the combined CoQ and ambroxol (ABX) treatment, in relative 1: 1 molar ratio, in vitro of Gaucher cells with the variant l444P / P415R in heterozygosis on the glucocerebrosidase enzyme activity. Glucocerebrosidase enzyme activity in fibroblasts derived from patients

15 Gaucher carriers of the L444P / P415R mutations in heterozygosis are also diminished compared to healthy control fibroblasts. The treatment with ambroxol (ABX), which acts as a pharmacological chaperone, at a concentration of 50 ... 1M, partially recovers the enzymatic activity (1.6 times more). To a lesser extent, but significantly, coa treatment also allows

20 obtain greater glucocerebrosidase activity in cells derived from Gaucher patients (1.2 times more). The combined treatment of both compounds in a 1: 1 relative mole ratio achieves a significant improvement in activity levels (2.8 times).
