METHOD OF TREATING NEURODEGENERATIVE AND OCULAR NEO VASCULAR DISEASESCROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This patent application claims the benefit of U.S. Provisional Patent Application No. 63 / 633,115, filed April 12, 2024, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION
[0002] Lipoprotein-associated phospholipase A2 (Lp-PLA?) previously known as plateletactivating factor acetylhydrolase (PAF-AH), is a phospholipase A2 enzyme involved in hydrolysis of lipoprotein lipids or phospholipids. Lp-PLA2 travels with low-density lipoprotein (LDL) and rapidly cleaves oxidized phosphatidylcholine molecules derived from the oxidation of LDL. See, for example, Zalewski et al., Arterioscler. Thromb. Vase. Biol.. 25(5): 923-931 (2005). Lp-PLA2 hydrolyzes the sn-2 ester of the oxidized phosphatidylcholines to provide lipid mediators, lyso-phosphatidylcholine (lysoPC) and oxidized nonesterified fatty acids (NEFAs). It has been observed that lysoPC and NEFAs elicit inflammatory responses. See, for example, Zalewski et al. (2005).
[0003] A number of Lp-PLA2 inhibitors and / or uses thereof have been previously described. See, for example, U.S. Patent 9,783,546. The disclosed uses include treating disease that may be associated with the increased involvement of monocytes, macrophages, or lymphocytes, with the formation of lysophosphatidylcholine and oxidized free fatty acids, with lipid oxidation in conjunction with Lp-PLA2 activity, or with endothelial dysfunction. Examples of such diseases include neurodegeneration disease (e.g., Alzheimer's disease, Parkinson's disease, Huntington's disease, and vascular dementia), atherosclerosis, stroke, metabolic bone disorder (e.g., bone marrow abnormalities), dyslipidemia, Paget's diseases, type II diabetes, metabolic syndrome, insulin resistance, hyperparathyroidism, diabetic ocular disorder (e.g., macular edema, diabetic retinopathy, and posterior uveitis), macular edema, wound healing, rheumatoid arthritis, chronic obstructive pulmonary disease (COPD), psoriasis, and multiple sclerosis.
[0004] In view of the number of pathological responses that are mediated by Lp-PLA2, attempts have been made to prepare compounds that inhibit its activity. Though a number of such compounds have been disclosed in the art, attempts at treating such diseases have notbeen sufficiently successful. As such, there remains a need to develop methods of treating neurodegenerative and ocular neovascular diseases. The invention disclosed herein provides such methods of treating disease. These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.BRIEF SUMMARY OF THE INVENTION

[0011] In some embodiments, the neurodegenerative disease is Alzheimer’s disease. In certain embodiments, the Alzheimer’s disease is clinical, pre-clinical, or prodromal Alzheimer's disease.
[0012] In some embodiments the neurodegenerative disease is Down’s syndrome, cerebral amyloid angiopathy, vascular dementia, or dementia caused by neurodegeneration. In certain embodiments, the cerebral amyloid angiopathy is clinical or pre-clinical cerebral amyloid angiopathy.
[0013] In some embodiments, the ocular neovascular disease is diabetic retinopathy, proliferative diabetic retinopathy, retinal vein occlusion, central retinal vein occlusion, branched retinal vein occlusion, diabetic macular edema, diabetic retinal ischemia, ischemicretinopathy, or diabetic retinal edema. In certain embodiments, the ocular neovascular disease is diabetic macular edema.
[0014] As used herein, unless otherwise indicated, “disease” refers to any alteration in state of the body or of some of the organs, interrupting or disturbing the performance of the functions and / or causing symptoms such as discomfort, dysfunction, distress, or even death to the person afflicted or those in contact with a person. A disease can also include a distemper, ailing, ailment, malady, disorder, sickness, illness, complaint, interdisposition, and / or affectation.
[0015] As used herein, unless otherwise indicated, “neurodegenerative disease” refers to a class of neurological disease where the neurological disease is characterized by a gradual and progressive loss of neural tissue, and / or altered neurological function, typically reduced neurological function as a result of a gradual and progressive loss of neural tissue. This gradual loss may take place in the brain or outside of the brain where nerve cells are present. In certain embodiments, the neurodegenerative diseases described herein include neurodegenerative diseases where there is a defective blood-brain barrier, for example, a permeable blood-brain barrier. In certain embodiments, the neurodegenerative diseases described herein include neurodegenerative diseases caused by the deterioration of the bloodbrain barrier. Examples of neurodegenerative diseases where there is a defective blood-brain barrier include, but are not limited to, Alzheimer's disease, Huntington's disease, Parkinson's disease, vascular dementia, and the like. In some embodiments, the neurodegenerative diseases described herein include neurodegenerative diseases caused by adverse effects derived from LysoPC and NEFAs. In certain embodiments, the neurodegenerative diseases described herein include neurodegenerative diseases caused by adverse effects derived from LysoPC. In certain embodiments, the neurodegenerative diseases described herein include neurodegenerative diseases caused by adverse effects derived from NEFAs.
[0016] As used herein, unless otherwise indicated, “vascular dementia” is also referred to as “multi-infarct dementia,” which refers to a group of syndromes caused by different mechanisms, which all result in vascular lesions in the brain. The main subtypes of vascular dementia are, for example, vascular mild cognitive impairment, multi-infarct dementia, vascular dementia due to a strategic single infarct (affecting the thalamus, the anterior cerebral artery, the parietal lobes, or the cingulated gyrus), vascular dementia due to hemorrhagic lesions, small vessel disease (including, for example, vascular dementia due to lacunar lesions and Binswanger disease), and mixed dementia.

[0028] As used herein, “pharmaceutically acceptable excipient” means a pharmaceutically acceptable material, composition, carrier, or vehicle involved in providing form or consistency to the pharmaceutical composition. Each excipient may be compatible with the other ingredients or components of the pharmaceutical composition when commingled, such that interactions which would substantially reduce the efficacy of the compound of the invention when administered to a subject and interactions which would result in a pharmaceutical composition that is not pharmaceutically acceptable are avoided.
[0029] The compound of the invention and the one or more pharmaceutically acceptable excipients may be formulated into a dosage form adapted for administration to the subject by the desired route of administration. For example, dosage forms include those adapted for (1) oral administration (including buccal or sublingual) such as tablets, capsules, caplets, pills, troches, powders, syrups, elixirs, suspensions, solutions, emulsions, sachets, and cachets, (2) parenteral administration (including subcutaneous, intramuscular, intravenous or intradermal) such as sterile solutions, suspensions, and powders for reconstitution, (3) transdermal administration such as transdermal patches, (4) rectal administration such as suppositories, (5) nasal inhalation such as dry powders, aerosols, suspensions, and solutions, and (6) topical administration (including buccal, sublingual or transdermal) such as creams, ointments,lotions, solutions, pastes, sprays, foams, and gels. Such compositions may be prepared by any methods known in the art of pharmacy, for example, by bringing into association a compound of the invention with one or more excipients.
[0030] Pharmaceutical compositions adapted for oral administration may be presented as discrete units such as capsules or tablets; powders or granules; solutions or suspensions in aqueous or non-aqueous liquids; edible foams or whips; or oil-in-water liquid emulsions or water-in-oil liquid emulsions.
[0031] Suitable pharmaceutically acceptable excipients may vary depending upon the particular dosage form chosen. In addition, suitable pharmaceutically acceptable excipients may be chosen for a particular function that they may serve in the composition. For example, certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate the production of uniform dosage forms. Certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate the production of stable dosage forms. Certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate carrying or transporting the compound or compounds of the invention once administered to the subject from an organ, or a portion of the body, to another organ, or a portion of the body. Certain pharmaceutically acceptable excipients may be chosen for their ability to enhance patient compliance.

A total of 5 (18%) participants had at least 1 treatment-related TEAE, comprising 3 (13%) participants in the compound overall group and 2 (40%) participants in the placebo group. The most frequently reported TEAEs were headache, catheter site pain, catheter site swelling, and dizziness. All the reported AEs were mild or moderate in intensity and none of the AEs led to withdrawal from the study. No apparent dose-dependent increase in the frequency and severity of AEs was observed.[OHl] A summary of adverse events is outlined in Table 2.Table 2 - Summary of Adverse Events in the MAD Study.
[0112] The results of this study indicated that once daily repeated doses of up to 180 mg for 14 days were safe and well tolerated.EXAMPLE 3
[0113] This example evaluated the pharmacokinetic (PK) profile of ( ?)-3-((3,5-difluoro- 4-((2-(trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)-7, 8, 8a, 9-tetrahydro- 114,614- pyrrolo[r,2':3,4]imidazo[l,2-c]pyrimidin-l-one when administered to human subjects in a single ascending dose (SAD) study.
[0114] Participants were administered a single oral dose of either 1 mg, 5 mg, 20 mg, 60 mg, or 180 mg, and PK plasma samples for concentration determination were collected atpre-dose (0 h) on Day 1 (DI) and at 0.5, 1, 2, 3, 4, 5, 6, 9, 12 h, 24 h (D2), 48 h (D3), 72 h (D4), and 96 h (D5) post dose. The plasma concentrations were determined by a validated liquid chromatography with tandem mass spectrometry (LC-MS / MS) method. The PK parameters including maximum plasma concentration (Cmax), the time it takes to reach the maximum concentration (Tmax), the area under the curve from the time of dosing to the last measureable concentration (AUCiast), the area under the curve from the time of dosing extrapolated to infinity (AUCO-INF), the half-life (T1 / 2), the volume of distribution based on the terminal elimination phase following extravascular administration (Vz / F), and the total body clearance following extravascular administration (CL / F) were determined by noncompartmental analysis.
[0115] The results of this study indicated that (R)-3-((3,5-difluoro-4-((2- (trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)-7,8,8a,9-tetrahydro-lH,6H- pyrrolo[l',2':3,4]imidazo[l,2-c]pyrimidin-l-one had low plasma clearance, moderate intersubject variability and suitable elimination half-life for once daily dosing in human subjects. A dose-proportional increase in exposure from 1 mg to 180 mg was observed.EXAMPLE 4
[0116] This example evaluated the pharmacokinetic (PK) profile of (7?)-3-((3,5-difluoro- 4-((2-(trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)-7,8,8a,9-tetrahydro-lH,6H- pyrrolo[l',2':3,4]imidazo[l,2-c]pyrimidin-l-one when administered to human subjects in a multiple ascending dose (MAD) study.
[0117] Participants were administered once daily oral doses of either 30 mg, 90 mg, or 180 mg for 14 days, and plasma PK samples for concentration determination were collected at pre-dose (0 h) on Day 1 (DI), D2, D3, D5, D8, D12, and D14. Post-dose PK plasma samples were collected on DI and D14 at 0.5, 1, 2, 3, 4, 5, 6, 9, and 12 h post morning dose. In addition, PK plasma samples were collected on 24 h (DI 5), 48 h (DI 6), 72 h (DI 7), and 96 h (D18) post the D 14 morning dose. The plasma concentrations were determined by a validated LC-MS / MS method. PK parameters, including maximum concentration (Cmax), the time it takes to reach the maximum concentration (Tmax), the area under the curve over the dosing interval tau concentration (AUCo-tau), the half-life (T1 / 2), D14 / D1 observed accumulation ratio in exposure (Rac) were determined by non-compartmental analysis.
[0118] The results of this study indicated that (R)-3-((3,5-difluoro-4-((2- (trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)-7,8,8a,9-tetrahydro-lH,6H-pyrrolo[l',2':3,4]imidazo[l,2-c]pyrimidin-l-one had mild exposure accumulation (<1.5 folds) over repeated once daily dosing. In particular, a dose-proportional increase in exposure (AUCo-tau) from 30 mg to 90 mg and then a less than dose-proportional increase in AUCo-tau from 90 mg to 180 mg was observed after repeated once daily oral administration.EXAMPLE 5
[0119] This example evaluates the dose-dependent inhibition of plasma Lp-PLA2 activity of (A)-3-((3,5-difluoro-4-((2-(trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)-7,8,8a,9- tetrahydro-lH,6H-pyrrolo[r,2':3,4]imidazo[l,2-c]pyrimidin-l-one when administered to human subjects in a single ascending dose (SAD) study.
[0120] Participants were administered single oral doses of 1 mg, 5 mg, 20 mg, 60 mg, 180 mg, or placebo and the plasma samples for Lp-PLA2 activity were collected at pre-dose (0 h) on Day 1 (DI) and at 0.5, 1, 2, 3, 6, 12 h, 24 h (D2), 48 h (D3), 72 h (D4), and 96 h (D5) post dose. The plasma Lp-PLA2 activity was measured using the PLAC test and the percentage of Lp-PLA2 inhibition relative to the pre-dose baseline was calculated over a span of 96 h.
[0121] The results of this study indicated that (A)-3-((3,5-difluoro-4-((2- (trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)-7,8,8a,9-tetrahydro-lH,6H- pyrrolo[l',2':3,4]imidazo[l,2-c]pyrimidin-l-one had a dose- and concentration-dependent inhibition of plasma Lp-PLA2 activity. The percentage mean Lp-PLA2 inhibition was greater than 80% at 24 hours post dose in the participants administered doses of 5 mg, 20 mg, 60 mg, and 180 mg as compared to the pre-dose baseline (Table 3).Table 3 - The Percentage Mean Lp-PLAi Inhibition Versus Pre-dose Baseline at 24 Hours Post Dose in the SAD Study.EXAMPLE 6
[0122] This example evaluates the dose-dependent inhibition of plasma Lp-PLA2 activity of (7?)-3-((3,5-difluoro-4-((2-(trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)-7,8,8a,9- tetrahydro-lH,6H-pyrrolo[r,2':3,4]imidazo[l,2-c]pyrimidin-l-one when administered to human subjects in a multiple ascending dose (MAD) study.
[0123] Participants were administered once daily oral doses of 30 mg, 90 mg, or 180 mg, and the plasma samples for Lp-PLA2 activity were collected at pre-dose (0 h) on Day 1 (DI), D2, D3, D5, D8, D12, and D14. Post-dose plasma samples were collected on DI and D14 at 0.5, 1, 2, 3, 6, and 12 h post morning dose. In addition, plasma samples were collected on 24 h (D15), 48 h (D16), 72 h (D17), and 96 h (D18) post the D14 morning dose. The plasma Lp- PLA2 activity was measured using the PL AC test and the percentage of Lp-PLA2 inhibition relative to the Day 1 pre-dose baseline was calculated over a span of 432 h.
[0124] The resulting data indicated that all doses provided a higher percentage of Lp- PLA2 inhibition over 432 h. The percentage mean Lp-PLA2 inhibition was greater than 90% at trough at steady state in all doses as compared to the pre-dose baseline (Table 4).Table 4 - The Percentage Mean Lp-PLAi Inhibition Versus Pre-dose Baseline at Trough at Steady State in the MAD study.EXAMPLE 7
[0125] This example evaluates the cerebrospinal fluid (CSF) distribution of (7?)-3-((3 ,5- difluoro-4-((2-(trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)-7,8,8a,9-tetrahydro-lH,6H- pyrrolo[l',2':3,4]imidazo[l,2-c]pyrimidin-l-one when administered to human subjects.
[0126] Participants were administered an oral dose of 60 mg or placebo, and the CSF samples were taken at 2 h post administration by lumbar puncture. PK plasma samples for concentration determination were collected at pre-dose (0 h) on Day 1 (DI) and at 0.5, 1, 2, 3,4, 5, 6, 9, 12 h, and 24 h (D2) post dose. The CSF and plasma concentrations were determined by validated LC-MS / MS methods. The CSF-to-plasma unbound concentration ratio was calculated by correcting the CSF-to-plasma concentration ratio with plasma and brain tissue unbound fraction measured in vitro. The CSF Lp-PLA2 activity was measured by incubating CSF with probe substrate platelet-activating factor (PAF) for 60 minutes and the resultant hydrolyzed product lyso-PAF was quantified.
[0127] The CSF-to-plasma unbound concertation ratio was determined to be 1.2. The percentage mean Lp-PLA2 inhibition at approximately 2 hours post single oral dose of 60 mg was greater than 80% relative to that of the placebo group.
[0128] The results of this study indicated that (A)-3-((3,5-difluoro-4-((2- (trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)-7,8,8a,9-tetrahydro-lH,6H- pyrrolo[r,2':3,4]imidazo[l,2-c]pyrimidin-l-one was brain penetrable and substantially inhibited Lp-PLA2 activity in the central nervous system.EXAMPLE 8
[0129] This example evaluates the effect of a high-fat breakfast on the pharmacokinetic (PK) parameters of (A)-3-((3,5-difluoro-4-((2-(trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)- 7, 8,8a,9-tetrahydro- lH,6H-pyrrolo[ l',2' : 3 ,4]imidazo[ 1 ,2-c]pyrimidin- 1 -one when administered to human subjects.
[0130] Participants were administered an oral dose of 60 mg under fasted and fed state conditions in a cross-over manner and PK plasma samples for concentration determination were collected at pre-dose (0 h) on Day 1 (DI) and at 0.5, 1, 2, 3, 4, 5, 6, 9, 12 h, 24 h (D2), 48 h (D3), 72 h (D4), and 96 h (D5) post dose. The plasma concentrations were determined by a validated LC-MS / MS method. The PK parameters including maximum plasma concentration (Cmax), the time it takes to reach the maximum concentration (Tmax), the area under the curve from the time of dosing to the last measurable concentration (AUCiast), the area under the curve from the time of dosing extrapolated to infinity (AUCO-INF), the half-life (T1 / 2), the volume of distribution based on the terminal elimination phase following extravascular administration (Vz / F), and the total body clearance following extravascular administration (CL / F) were determined by non-compartmental analysis.
[0131] The results of this study indicated that the intake of high-fat food led to a minor increase in AUC exposure (26%), a slight decrease in peak concentration (20%), a delayed Tmax, and had no effect on the terminal half-life and exposure variability.EXAMPLE 9
[0132] This example evaluated the induction effect of (R)-3-((3,5-difhroro-4-((2- (trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)-7,8,8a,9-tetrahydro-lH,6H- pyrrolo[l',2':3,4]imidazo[l,2-c]pyrimidin-l-one on metabolizing enzyme CYP3A when administered to human subjects in a multiple ascending dose (MAD) study.
[0133] Participants were administered once daily oral doses of either 30 mg, 90 mg, 180 mg, or a placebo and plasma samples for 4P-hydroxycholesterol (an endogenous marker of CYP3A activity in humans) concentration were collected at pre-dose on Day 1 (DI) and Day 14 (D14). The plasma concentrations of 4P-hydroxycholesterol were determined by a validated LC-MS / MS method. Treatment effect on plasma 4P-hydroxycholesterol will be assessed using an analysis of covariance model of log-transformed D14 / D1 concentration ratio.
[0134] The mean plasma Day 14 / Day 1 ratios of 4P-hydroxy cholesterol concentrations showed no difference between the 30 mg and placebo-treated participants. However, the mean plasma Day 14 / Day 1 ratios of 4P-hydroxy cholesterol concentrations were slightly greater for the 90 mg and 180 mg treated participants compared to the placebo-treated participants in a dose-dependent manner.
[0135] The results of this study indicated that once daily oral doses of 180 mg or less of (7?)-3-((3,5-difluoro-4-((2-(trifluoromethyl)pyridin-4-yl)oxy)benzyl)oxy)-7,8,8a,9-tetrahydro- lH,6H-pyrrolo[r,2':3,4]imidazo[l,2-c]pyrimidin-l-one led to no CYP3A induction or low levels of CYP3 A induction.
