Description

[Technical Field]

[0001] Technical Field The present invention relates to an active pharmaceutical ingredient selected from N-[2-hydroxy-3-(1-piperidinyl)-propoxy]pyridine-1-oxide-3-carboximidoyl chloride, its stereoisomers and acid addition salts thereof, and in particular to arimoclomol for use in an improved method of treating Gaucher disease (GD). [Background technology]

[0002] background Gaucher disease is an autosomal recessive lysosomal storage disorder (LSD) characterized by a deficiency of the enzyme glucocerebrosidase (GBA). The enzyme deficiency is caused by mutations in the gene GBA1, which leads to the accumulation of glucosylceramide (GlcCer) and its deacylated form, glucosylsphingosine (GlcSph). Glucosylsphingosine accumulates in the brain and is thought to be responsible for the neurological symptoms of Gaucher disease.

[0003] This disease is characterized by lysosomal dysfunction, cellular stress, and death caused by a significant decrease in enzyme activity. It is most often due to the L444P mutation, the homozygosity of which is strongly associated with the GD3 genotype (GD3). The L444P genotype has previously been demonstrated to respond to several heat shock protein (HSP) induction strategies.

[0004] Gaucher disease has traditionally been classified into three subtypes based on the presence or absence of primary central nervous system (CNS) involvement: GD1 type (GD1) with no neurological symptoms, GD2 type (GD2) with acute early neurological disease, and GD3 with a slower, chronic neuropathic disease.

[0005] Clinical onset of GD1 can occur at any age, but when symptoms begin in childhood, the phenotype is typically more severe and progresses more rapidly. The most frequent manifestations of the disease are splenomegaly, hepatomegaly, and bone disease, accompanied by anemia and thrombocytopenia (primarily due to hypersplenism). Signs and symptoms associated with hepatosplenomegaly can range from absence to abdominal distension, discomfort, or pain. Thrombocytopenia leads to an increased tendency for bleeding and bruising, and anemia can cause fatigue and growth failure with low body weight and reduced growth. Bone marrow infiltration by Gaucher cells leads to osteopenia, osteonecrosis, and osteosclerosis, sometimes resulting in acute onset of severe pain (bone spasms), chronic bone pain, and pathological fractures, which substantially impact patients' quality of life.

[0006] Gaucher disease type 3 is characterized as a milder chronic neurological disorder compared with GD2 (acute type). Symptoms begin later in childhood, with or without visceral and bone marrow involvement as seen in GD1. The earliest CNS involvement can be assessed by a detailed ophthalmologic examination, revealing abnormalities in horizontal saccade initiation, strabismus, and ocular palsy or paresis. Neurological progression is characterized by severe hypertonia, rigid arches (opisthotonus), ataxia, dysphagia, and seizures. Visceral disease in GD3 is often more severe than in GD1. Clinical scoring scales have been developed and validated to assess disease severity and the potential clinical benefit of treatment in both GD1 and GD3.

[0007] Two types of treatments are currently available for GD patients: enzyme replacement therapy (ERT), which uses recombinant GBA enzyme, and substrate reduction therapy (SRT), which acts by inhibiting GlcCer synthase, thereby reducing substrate production. Both types of treatment improve peripheral features of the disease but do not improve neurological symptoms and are therefore ineffective in treating neuropathic GD.

[0008] The accumulation of GlcCer and GlcSph in lysosomes occurs primarily in mononuclear macrophages, resulting in phagocytic macrophages called "Gaucher cells." In brain tissue from GD patients with neurological symptoms, neuronal loss and shrunken, atrophic neurons have been reported in the basal ganglia and nuclei of the midbrain, pons and medulla, cerebellum, dentate nucleus, and hypothalamus.

[0009] Chronic stimulation of the immune system occurs due to activated macrophages. Although there is considerable variability between patients, elevated levels of several interleukins ([IL]-1α, IL-1β, IL-1Ra, sIL-2R, IL-6, IL-8, IL-10, IL-18), tumor necrosis factor (TNF)-α, transforming growth factor-β, macrophage colony-stimulating factor, macrophage inflammatory protein-1 (MIP-1), and chemokine (CC motif) ligand 18 have been reported. The most important biomarker, chitotriosidase, is an enzyme produced in large amounts by macrophages and neutrophils. Histochemistry of bone marrow aspirates and spleen sections reveals these reservoir cells.

[0010] The HSR is an important homeostatic system that is induced under conditions of metabolic stress (e.g., protein misfolding and aggregation, nutrient deprivation, oxidative stress, or heat stress). Its main components are HSPs (especially HSP70), which have significant cytoprotective properties. Heat shock protein 70 acts as a molecular chaperone, assisting the folding of newly synthesized damaged proteins, preventing protein aggregation, and targeting severely damaged proteins for degradation. Notably, the cytoprotective effects of HSP70 include protection against lysosomal dysfunction, cell death, and demyelination in mouse studies. Arimoclomol is a safe and well-tolerated co-inducer of HSP70 expression that acts through activation of heat shock factor-1, a key regulator of HSP gene transcription. It is available for oral administration and exhibits the ability to cross the blood-brain barrier. Summary of the Invention

[0011] Abstract A double-blind, randomized, placebo-controlled, phase 2 dose-ranging study was conducted at seven centers in India in patients with Gaucher disease (GD) types 1 and 3 who were not receiving enzyme and / or substrate replacement therapy. A total of 39 patients were randomized 1:1:1:1 to receive placebo or 100 mg, 200 mg, or 400 mg of arimoclomol citrate (weight-adjusted) three times daily. The objective of the phase 2 study was to evaluate the response of three dose levels of arimoclomol on various clinical and disease-specific biomarkers over a 6-month treatment period. Overall, 37 patients were included in the analysis set (two patients were excluded because they had negative confirmatory GD genotypes), of which 21 were type 1 GD patients and 16 were type 3 GD patients.

[0012] The data presented herein demonstrate a dose-dependent effect of arimoclomol on certain disease-related secondary clinical endpoints, including liver and spleen size. Arimoclomol also demonstrated a relative decrease in serum chitotriosidase activity, and patients with baseline anemia demonstrated a time-dependent increase in hemoglobin at the highest dose.

[0155] In some embodiments, the composition is formulated for oral administration, e.g., in the form of a tablet or capsule, or as an oral powder, e.g., an oral powder suitable for suspension in a liquid, or e.g., as a suspension for oral administration.

[0156] Pharmaceutical compositions containing the active pharmaceutical ingredients of the present disclosure may be prepared by conventional techniques. [Example]

[0157] Example 1 - A multicenter, double-blind, randomized, placebo-controlled trial of arimoclomol in patients diagnosed with Gaucher disease type 1 or type 3 material and method Methods / Study Design This is a placebo-controlled, randomized, double-blind study evaluating the response of three dose levels of arimoclomol to various pharmacodynamic (PD) biomarkers in blood and cerebrospinal fluid (CSF) as indicators of enhanced glucocerebrosidase (GBA) enzyme activity on GD1 and GD3.

[0158] The purpose of this study was to evaluate whether arimoclomol can dose-dependently increase GBA enzyme activity in patients with GD. Changes in serum levels of well-established biomarkers related to GBA enzyme activity, as well as changes in hemoglobin and platelet counts, were assessed over a double-blind, 6-month period and compared with placebo. Because both GD1 and GD3 patients have signs of cerebral involvement (although nonclinical in GD1 patients), the same panel of biomarkers was assessed in the CSF of GD1 and GD3 patients.

[0159] Eligible GD1 and GD3 patients were randomized on a 1:1:1:1 basis into four groups to receive arimoclomol 300 mg / day, arimoclomol 600 mg / day, arimoclomol 1200 mg / day, or placebo treatment (administered three times daily [tid]).

[0160] Pediatric patients received a corresponding dose based on their body weight (kilograms). Adult patients randomized to the study before the protocol implementation date received a fixed dose, and adult patients randomized to the study after the protocol implementation date received an IMP dose based on their body weight. Patients were stratified according to GD type (type 1 or 3). Patients randomized to receive placebo were further randomized on a 1:1:1 basis to receive arimoclomol at 300 mg / day, 600 mg / day, or 1200 mg / day (in the absence of safety concerns) in the open-label extension phase of the study.

[0161] If an unacceptable adverse event (AE) occurred, as determined by the investigator, the patient received a reduced dose of the investigational product (IMP) until visit 3. Patients continued on the reduced dose for the remainder of the study.

[0162] All patients received a single dose of arimoclomol (100 mg single dose for the 300 mg / day treatment group, 200 mg single dose for the 600 mg / day treatment group, or 400 mg single dose for the 1200 mg / day treatment group, or the corresponding dose per kg for pediatric patients) before the protocol implementation date. Single-dose pharmacokinetics (PK) was performed at the corresponding dose per kg for all patients randomized after the protocol implementation date. PK evaluation was performed at the second postrandomization visit to confirm the suitability of the dose selected for this study (in terms of the target test drug (AUC0-8 - area under the curve from 0 to 8 hours [AUC] [AUC0-8])). After the single dose, blood samples for PK analysis were collected pre-dose and 0.5, 1, 2, 4, and 8 hours after administration. Patients randomized to the placebo group received the extension phase dose. The corresponding data were evaluated by an independent assessor to verify the AUC0-8. Patients then immediately began continuous administration of IMP according to randomization. IMP was administered three times daily (tid).

[0163] If the AUC was above target or an unexpected profile potentially affecting patient safety resulted in a dose reduction, patients received the reduced dose of IMP (blinded) on Visit 3. The dose level was recommended by an independent assessor. Additional blood samples for quantitative population pharmacokinetic analysis of arimoclomol were collected pre-dose and 0.5 hours post-dose on Visit 5 and pre-dose and 1.5 hours post-dose on Visit 7.

[0164] Cerebrospinal fluid samples for quantitative population pharmacokinetic analysis of arimoclomol were collected predose at Visit 5 and after the first daily dose at Visit 7. Results of the population pharmacokinetic analysis and PK / PD modeling were reported separately. Following the proof-of-concept phase, all patients were offered the opportunity to continue into the open-label extension phase, during which patients attended the site 1 month after the end of the blinded phase visit and every 6 months after the end of the blinded phase visit. During this open-label extension phase, patients who received arimoclomol during the proof-of-concept phase of the study continued on the same arimoclomol dose assigned to them, while patients who received placebo received arimoclomol 300 mg / day, 600 mg / day, or 1200 mg / day (adult patients) or the corresponding weight-adjusted dose (pediatric patients). All patients randomized after the protocol implementation date received an IMP dose based on weight.

[0165] Study population and patient numbers Male and female patients aged 4 to 60 years with a diagnosis of GD (either type 1 or type 3) comprised the study population. 40 patients were expected to be enrolled / randomized in the study.

When dispersed, IMP was also administered via a gastric tube (if applicable). The tube was flushed with 5 mL of water for complete administration.

[0178] Dosage and Regimen For patients randomized prior to the implementation date of this protocol, the dose was administered in mg three times daily based on the patient's weight. (See Table 1 below.) For pediatric patients, the dose was administered according to weight as shown in Table 1 below. Adult patients (age 18 and older) received the fixed dose shown in Table 1 below.

[0179] [Table 1]

[0180] All patients, including adult patients randomized into the study after the implementation date of this protocol, received an IMP dose based on body weight, as shown in Table 2 below.

[0181] [Table 2]

[0182] Efficacy assessment Primary endpoint The primary efficacy endpoint of the study was the percent change in serum chitotriosidase activity (a marker of macrophage activation) from baseline to 6 months, with baseline defined as the mean of the pre-treatment visits (visits 1 and 2).

[0183] Secondary endpoints Measurement of growth and maturation Patients under 18 years of age: Changes in weight / height curves at 6 months and every other year until the end of the study Age at onset of puberty (Tanner stage II) in patients who had not reached puberty at the time of screening. Tanner stage (Tanner stages I to IV) at baseline and 6 months, and at least every 12 months thereafter until the end of the study. For adult patients aged 18 years and older, clinical efficacy outcomes were as follows: Change from baseline in body weight at 6 months and every 12 months thereafter until the end of the study

[0184] Imaging Endpoints Imaging efficacy endpoints consisted of changes in liver and spleen size (in centimeters) (assessed by ultrasound) at 6 months and every other year through the end of the study.

[0185] Clinical GD Severity Endpoints (All Patients): Gaucher disease type 1 disease severity scoring system (GD1-DS3) Modified Severity Scoring Tool (mSST)

[0186] Exploratory Endpoints Other exploratory endpoints included blood and CSF biomarker analysis and patient acceptability / preference for IMP.

[0187] Exploratory biomarker endpoints measured in blood included: Changes in plasma glucosylsphingosine (GlcSph) levels at 6 months and every 6 months until the end of the study * Changes in hemoglobin, ferritin, and platelet levels at 6 months and every 6 months until the end of the study * Changes in GBA enzyme activity (white blood cells) at 6 months and every 6 months until the end of the study * Changes in serum macrophage inflammatory protein-1b (MIP-1β, a cytokine for bone complications) at 6 months and every 6 months until the end of the study * * Change from baseline (Baseline defined as the mean of the pre-treatment visits (Visit 1 and Visit 2))

[0188] Exploratory biomarker endpoints measured in CSF included: Changes in glycoprotein nontransferase B at 6 and 12 months ** Changes in GlcSph levels at 6 and 12 months ** Changes in chitotriosidase activity (a marker of macrophage activation) at 6 and 12 months ** Changes in GBA enzyme activity levels at 6 and 12 months ** Changes in heat shock protein 70 levels at 6 and 12 months ** ** Change from the second visit to 6 or 12 months after the second visit

[0189] Pharmacokinetics Blood samples were collected after the first dose (visit day 2) at the following time points: 0.5, 1, 2, 4, and 8 hours post-dose. AUC0-8 after the first dose was used to assess whether exposure levels were acceptable. Additional blood samples for quantitative population PK analysis of arimoclomol plasma concentrations were collected pre-dose and 0.5 hours post-dose at visit day 5 and pre-dose and 1.5 hours post-dose at visit day 7.

[0190] Cerebrospinal fluid samples for quantitative population PK analysis of arimoclomol CSF concentrations were collected pre-dose at visit 5 and after the first daily dose at visit 7.

[0191] statistical methods The primary efficacy endpoint was analyzed using an analysis of covariance (ANCOVA) model for the ITT population. Logarithmic chitotriosidase activity was used for the analysis. The response variable in the ANCOVA model was logarithmic chitotriosidase activity at 6 months, and the independent variables included the randomized IMP dose (300 mg / day, 600 mg / day, 1200 mg / day, and 0 mg / day [placebo]), GD type, and logarithmic baseline chitotriosidase activity as continuous variables. An ancillary analysis was performed using the same model, but using the actual dose administered at Visit 3 after dosing adjustment based on potential PK assessments at Visit 2.

[0192] The following ANCOVA model was used to correlate the log of drug concentrations in blood and CSF with chitotriosidase activity in the blood / CSF population at 6 months: ANCOVA model for log of CSF drug concentration measured on visit 5, GD type, and log of baseline chitotriosidase activity as covariates. ANCOVA model for the log of blood drug concentration measured on visit 5, GD type, and the log of baseline chitotriosidase activity as covariates.

[0193] Secondary efficacy endpoints, including changes in weight and height, liver size, spleen size, and changes in biomarkers (blood and CSF) versus baseline (if appropriate), were analyzed using an ANCOVA model with treatment group (actual dose administered at Visit 3 after possible dosing adjustment based on PK assessment at Visit 2, or placebo) and corresponding baseline values ​​as covariates. For biomarker analysis, appropriate data transformations were performed, if necessary, prior to statistical analysis.

[0194] Descriptive statistics for age at pubertal onset and Tanner stage were provided by treatment group. No inferential analyses were performed.

[0195] Safety assessments included the following endpoints: incidence and severity of AEs (or treatment-emergent AEs [TEAEs]), C-SSRS, and mean and change from baseline, as well as laboratory safety laboratory and vital sign data considered clinically important. No formal statistical analysis of safety data was performed.

[0196] Arimoclomol plasma and CSF concentrations were summarized using descriptive statistics and by visit day and time point. The AUC0-8 after the first dose (visit day 2) was assessed using noncompartmental methods. Estimated AUC0-8 for each patient was listed.

[0197] The relationship between arimoclomol plasma and CSF concentrations and biomarkers was investigated. All plasma and CSF arimoclomol concentration and dosing data were combined with PK sampling date and time and used to create a population PK input file for use in population PK modeling analysis. Furthermore, the relationship between arimoclomol PK (plasma / CSF) and biomarkers was also investigated using a population PK / PD modeling approach.

[0198] Treatment period The proof-of-concept phase of the study was six months in duration. The open-label extension phase will continue until arimoclomol receives Marketing Authorisation (MA) in India or until analysis of data from the proof-of-concept phase of the study or information from the development programme, whichever comes first, no longer warrants its continuation.

[0199] Duration of patient participation in the study Randomization (Visit 2) occurred 7 to 35 days after screening (Visit 1). During the proof-of-concept, double-blind, placebo-controlled period of the study, patients visited the study at 1 month (Visit 3), 3 months (Visit 4), and 6 months (Visit 5 [end of blinded period]) after Visit 2. During the open-label extension phase of the study, patients visited the study at 1 month (Visit 6), 3 months (Visit 6.1), 6 months (Visit 7), and every 6 months thereafter until the end of the study. The total duration of patient participation in the study depended on the date of the MA in India or the availability of relevant data from the development program.

[0200] result Treatment Groups and Important Baseline Characteristics Thirty-nine subjects were randomized into the intention-to-treat (ITT) population, but two patients were excluded from the ITT set due to negative confirmatory GD genotype analysis (post-hoc). There were 31 children and 6 adults in the ITT analysis set.

[0201] The number of patients in each treatment group and their baseline characteristics are summarized in Table 3 below.

[0202] [Table 3]

[0203] Dose-dependent plasma exposure of arimoclomol Plasma exposure (AUC) was estimated for each patient using population PK modeling. A dose-dependent increase in plasma exposure was observed following administration of arimoclomol (see Figure 1).

[0204] Clinical findings Primary endpoint Chitotriosidase activity increased across all treatment groups, with a lower increase in the arimoclomol group compared to placebo. Although significance was not achieved (p=0.4), a relative decrease in chitotriosidase activity from baseline was observed in all dose groups compared to placebo (see Figure 2).

[0205] Secondary Clinical Endpoints Clinically significant dose-dependent reductions in liver size (dose trend effect p<0.05) and spleen size (dose trend analysis p<0.10) were observed compared to placebo (see Figures 3 and 4). The strong correlation between liver and spleen size and treatment (correlation coefficient: 0.53) confirms the consistency of effect.

[0206] Patients in the higher dose group who were anemic at baseline showed a time-dependent increase in hemoglobin (time trend analysis p<0.05) (see Figure 5).

[0207] A dose-dependent reduction in a validated clinical composite measure of Gaucher disease type 1 (the "Clinical GD1 Severity Score") was also observed, although this did not achieve statistical significance.

[0208] Other exploratory biomarkers: A trend towards a dose-dependent increase in glycosylsphingosine (lyso-Gb1) was observed (see Figure 6), but did not achieve statistical significance.
