Cardiovascular disease is a class of diseases that involve the heart and blood vessels. Atherosclerosis is thought to be a major cause of cardiovascular disease. Atherosclerosis, or the narrowing and hardening of arteries caused by a buildup of plaque, can lead to, e.g., heart attacks (myocardial infarction), strokes, peripheral vascular disease, and coronary artery disease. Atherosclerosis is a heavy burden to our modern society. Preclinical data suggest 2-hydroxypropyl-beta-cyclodextrins could have profound beneficial effects on the pathomechanisms responsible for atherosclerotic disease development and arrest or reverse the progression of cardiovascular disease. Therefore, 2-hydroxypropyl-beta-cyclodextrins may provide a novel treatment option for cardiovascular disease.

It should be understood that, in some cases, “an effective amount” or “a therapeutically effective amount” varies from subject to subject, due to variation in metabolism of the composition, age, weight, general condition of the subject, concomitant medications the subject may be taking, the condition being treated, the severity of the condition being treated, and the judgment of the prescribing physician. In some instances, the disease or condition being treated is atherosclerotic cardiovascular disease (e.g., coronary artery disease (CAD)), or consequential diseases caused by atherosclerotic cardiovascular disease. In some cases, the disease or condition being treated is atherosclerosis. In some instances, the methods may be used to treat and/or prevent an underlying cause of atherosclerotic cardiovascular disease (e.g., CAD). The underlying cause of atherosclerotic cardiovascular disease may be, e.g., early vascular alterations (e.g., stiffening, impairments), calcification, plaque accumulation in the arteries and/or veins, elevation in circulating levels of lipids, inflammation, cholesterol accumulation, plaque formation, vessel occlusion, plaque rupture, and/or ischemia.
Methods of Treating Atherosclerotic Cardiovascular Disease
Examples 2-4 herein depict data demonstrating increased plasma cholesterol crystal dissolution capacity, increased oxysterol levels, and increased mRNA levels of the LXR transcription factor-regulated genes ABCA1 and ABCG1 in a human subject treated with 2-hydroxypropyl-beta-cyclodextrin. The data suggests that 2-hydroxypropyl-beta-cyclodextrin may be used to treat atherosclerosis and/or atherosclerotic cardiovascular disease, as described herein.
Disclosed herein are methods for treating a subject having, suspected of having, or at risk of developing atherosclerotic cardiovascular diseases. The atherosclerotic cardiovascular disease may be, e.g., CAD, PAD, PVD, stroke, chronic kidney disease (CKD) caused or contributed to by atherosclerosis, end-stage kidney disease (ESKD) caused or contributed to by atherosclerosis, acute kidney failure caused or contributed to by atherosclerosis, atherosclerotic renovascular disease (ARVD), renal artery stenosis, aortic aneurysm, idiopathic peripheral atrial hypertension, erectile dysfunction, intermittent claudication, and/or post-surgical or iatrogenic arterial disease. Further disclosed herein are methods for treating a subject having, suspected of having, or at risk of developing atherosclerosis. In some cases, the methods involve treating a subject having, suspected of having, or at risk of developing acute coronary syndrome (ACS) or chronic coronary syndrome (CCS) (e.g., as defined by the European Society of Cardiology). In some cases, treating a subject as described herein may inhibit, prevent, or reduce the development of atherosclerotic plaques (e.g., cholesterol-rich plaques and/or lipid-rich plaques) in the subject. In some cases, treating a subject as described herein may mediate, promote, enhance, or increase the regression of already-developed atherosclerotic plaques (e.g., cholesterol-rich plaques and/or lipid-rich plaques). In some cases, treating a subject as described herein may result in fewer atherosclerotic plaques in the subject, smaller atherosclerotic plaques in the subject, or both. In some cases, reducing the number and/or size of atherosclerotic plaques in the subject may ameliorate, prevent, or reduce one or more symptoms associated with atherosclerosis and/or atherosclerotic cardiovascular disease (e.g., CAD).
In various aspects, the methods involve administering a cyclodextrin to a subject. Cyclodextrins are a family of cyclic oligosaccharides, consisting of a cyclic (e.g., macrocyclic) ring of glucose subunits joined by α-1,4 glycosidic bonds. Cyclodextrins contain a number of glucose monomers in a ring formation. Common cyclodextrins include alpha-cyclodextrins (consisting of six glucose monomers), beta-cyclodextrins (consisting of seven glucose monomers), gamma-cyclodextrins (consisting of eight glucose monomers), and delta-cyclodextrins (consisting of nine glucose monomers). The outer portion of the ring structure is hydrophilic and the inner cavity of the ring structure is hydrophobic; thus, cyclodextrins generally are water soluble (e.g., due to the hydrophilic exterior), and capable of incorporating hydrophobic molecules in the cavity (e.g., due to the hydrophobic cavity). Parent cyclodextrins have limited water solubility; therefore, several chemically modified cyclodextrins have been synthesized where the hydroxyl groups are substituted with other chemical moieties to increase solubility. In various aspects, the methods provided herein involve administering a cyclodextrin to a subject (e.g., a human) in need thereof (e.g., having, suspected of having, or at risk of developing atherosclerosis and/or atherosclerotic cardiovascular disease (e.g., CAD)). In some cases, the subject has, is suspected of having, or is at risk of developing atherosclerotic plaques (e.g., cholesterol-rich plaques and/or lipid-rich plaques).

In some instances, the 2-hydroxypropyl-beta-cyclodextrin is selected from the group consisting of: Kleptose® HP Parenteral Grade (Roquette Frères, #346114; accessible at roquette.com/-/media/roquette-sharepoint-libraries/sdol_product-specification-sheet/roquette_quality_specification-sheet_kleptose-hp-parenteral-grade_50_346114 en.pdf as of Aug. 26, 2020), Kleptose® HPB Parenteral Grade (Roquette Frères, #346111; accessible at roquette.com/-/media/roquette-sharepoint-libraries/sdol_product-specification-sheet/roquette_quality_specification-sheet_kleptose-hpb-parenteral-grade_50_346111 en.pdf as of Aug. 26, 2020), Kleptose® HPB-LB Parenteral Grade (Roquette Frères, #346115; accessible at roquette.com/-/media/roquette-sharepoint-libraries/sdol_product-specification-sheet/roquette_quality_specification-sheet kleptose-hpb-lb-parenteral-grade_50_346115 en.pdf as of Aug. 26, 2020), Cavitron® W7 HP5 Pharma cyclodextrin (Ashland; accessible at ashland.com/file_source/Ashland/Product/Documents/Pharmaceutical/PC_11734_Cavitron_Cavasol.pdf as of Aug. 26, 2020), Cavitron® W7 HP7 Pharma cyclodextrin (Ashland; accessible at ashland.com/file_source/Ashland/Product/Documents/Pharmaceutical/PC_11734_Cavitron_Cavasol.pdf as of Aug. 26, 2020), Trappsol® Cyclo™ (Cyclo Therapeutics, Inc.; accessible at cyclotherapeutics.com/cyclodextrins/trappsol-cyclo as of Aug. 26, 2020), and VTS-270/adrabetadex.
In certain embodiments, a cyclodextrin provided or used in a (e.g., pharmaceutical) composition or method or other application herein is a mixture of cyclodextrins; for example, in some embodiments, a 2-hydroxypropyl-beta-cyclodextrin provided herein comprises a mixture of 2-hydroxypropyl-beta-cyclodextrins. In some embodiments, a cyclodextrin molecule provided herein is optionally substituted with one or more chemical group, each chemical group independently being a hydroxypropyl group, a hydroxyethyl group, a methyl group, an ethyl group, a carboxymethyl group, a heptakis(2,6-di-O-methyl) group, a sulfoethyl group, a sulfopropyl group, and/or a sulfobutyl ethyl group, or its oligomer thereof. In some preferred embodiments, the cyclodextrin is a hydroxypropyl-beta-cyclodextrin, such as wherein one or more hydroxyl of the cyclodextrin is substituted with hydroxypropyl (e.g., 2-hydroxypropyl group). For example, one or more hydroxyl positions are substituted by one or more hydroxypropyl groups by substituting the H of the hydroxyl (OH) with a —CH2CH2(OH)CH3 group, such as illustrated in Formula I below. In some embodiments, the 2-hydroxypropyl-beta-cyclodextrin comprises a plurality of cyclodextrins with various different Degree of Substitution (DS) values and/or having a Molar Substitution (MS) value.
In some embodiments, the plurality of beta-cyclodextrin molecules in a beta-cyclodextrin (mixture of beta-cyclodextrin molecules) is characterized by an average molar substitution. The “molar substitution,” or “MS,” is the average number of substituents per glucose unit in the beta-cyclodextrin molecules. In some embodiments, MS is determined according to the procedures set forth in the USP monograph on Hydroxypropyl Betadex (USP NF 2015) (“USP Hydroxypropyl Betadex monograph”), incorporated herein by reference in its entirety. In some embodiments, the (e.g., pharmaceutical) compositions provided herein contain a plurality of beta-cyclodextrin molecules having an average MS of at least about 0.3. In some embodiments, the (e.g., pharmaceutical) compositions provided herein contain a plurality of beta-cyclodextrin molecules having an average MS of about 0.3 to 1.0.
In some embodiments, the plurality of beta-cyclodextrin molecules is characterized by average degree of substitution. The term “degree of substitution,” or “DS,” refers to the total number of substituents substituted directly or indirectly on a beta-cyclodextrin molecule. In some embodiments, the beta-cyclodextrin molecule may have one, or multiple, glucose units that are substituted by a substituent at a hydroxyl position. Thus, average DS refers to the total number of substituents in a population of beta-cyclodextrins divided by the number of beta-cyclodextrin molecules. In some embodiments, the average DS of the molecule is measured using Electron Spray Ionization-Mass Spectrometry (ESI-MS) analysis (e.g., HPLC-ESI-MS, etc.). In some embodiments, the average DS of the molecule is determined by peak heights of an electrospray MS spectrum. In some embodiments, the average DS of the molecule is determined by multiplying the MS by 7. In some embodiments, the (e.g., pharmaceutical) compositions provided herein contain a plurality of beta-cyclodextrin molecules having an average DS of about 2.0 to 7.0.
In some embodiments, any atom of the cyclodextrins described herein (e.g., 2-hydroxypropyl-beta-cyclodextrin) may be substituted with any suitable isotope. In a particular embodiment, any one or more hydrogen atoms of the cyclodextrins described herein (e.g., 2-hydroxypropyl-beta-cyclodextrin) may be substituted or replaced with deuterium atoms. Such cyclodextrins are expected to have similar or improved properties as compared to the original cyclodextrin that does not contain deuterium. Deuterium is a safe, stable, non-radioactive isotope of hydrogen. Compared to hydrogen, deuterium forms stronger bonds with carbon. In some instances, the increased bond strength imparted by deuterium can positively impact properties of the cyclodextrins, creating the potential for improved drug efficacy, safety, and/or tolerability. In addition, deuteration may cause decreased metabolic clearance in vivo, thereby increasing the half-life and circulation of the compound. At the same time, because the size and shape of deuterium are essentially identical to those of hydrogen, replacement of hydrogen by deuterium would not be expected to affect the biochemical potency and selectivity of the compound as compared to the original chemical entity that contains only hydrogen.
In various aspects, a therapeutically effective amount of 2-hydroxypropyl-beta-cyclodextrin is administered to the subject. In some embodiments, administration of a therapeutically effective amount of 2-hydroxypropyl-beta-cyclodextrin increases a circulating and/or systemic level of one or more derivative of cholesterol as compared to a baseline. In some embodiments, the one or more derivative of cholesterol is a by-product of cholesterol biosynthesis. In some embodiments, the one or more derivative of cholesterol comprises a hydrogenated product, products with differently hydrogenated 1H-cyclopenta[a]phenanthren-3-ol products, or products formed with a hydroxyl, epoxyl, or keto group. In some cases, the one or more derivative of cholesterol is an oxysterol or a sterol.
A therapeutically effective amount may be an amount of 2-hydroxypropyl-beta-cyclodextrin effective to increase a circulating and/or a systemic amount of one or more sterols and/or oxysterols in the subject as compared to a baseline. A circulating and/or systemic amount of a sterol and/or oxysterol may be an amount present in a biological sample of the subject (e.g., blood (e.g., whole blood), plasma, serum, and the like). In some cases, the level of a circulating and/or systemic sterol and/or oxysterol may be increased by at least about 10% as compared to a baseline (e.g., at 24 hours after treatment), (e.g., at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, or greater).

Generally, the circulating and/or systemic levels of sterols and oxysterols (e.g., after treatment with 2-hydroxypropyl-beta-cyclodextrin) are compared to a baseline level (e.g., a circulating and/or systemic level of the sterol and/or oxysterol in the subject prior to treatment with the 2-hydroxypropyl-beta-cyclodextrin). Non-limiting examples of sterols and oxysterols that may demonstrate increased levels (e.g., in the whole blood, plasma, and/or serum) by administration of 2-hydroxypropyl-beta-cyclodextrin include: 27-hydroxycholesterol, 24-hydroxycholesterol, and 25-hydroxycholesterol. In various aspects, the therapeutically effective amount of 2-hydroxypropyl-beta-cyclodextrin may be an amount sufficient to maintain or sustain the systemic and/or circulating level of the sterol and/or oxysterol for at least 24 hours after treatment (e.g., at least 36 hours, at least 48 hours, at least 72 hours, at least 96 hours).
In a particular aspect, a therapeutically effective amount of 2-hydroxypropyl-beta-cyclodextrin is an amount effective to increase a circulating and/or systemic amount of 27-hydroxycholesterol as compared to a baseline.

In a particular embodiment, the level of circulating and/or systemic 27-hydroxycholesterol may be increased to at least about 100 ng/mL. In another aspect, the level of circulating and/or systemic 27-hydroxycholesterol may be increased to at least about 40 ng per mg of total circulating and/or systemic cholesterol, for example, to at least about 50 ng per mg, to at least about 60 ng per mg, to at least about 70 ng per mg, to at least about 80 ng per mg, to at least about 90 ng per mg, or to at least about 100 ng per mg of total circulating and/or systemic cholesterol. In a particular aspect, the level of circulating and/or systemic 27-hydroxycholesterol may be increased to at least about 90 ng per mg of total circulating and/or systemic cholesterol.
Additionally or alternatively, a therapeutically effective amount of 2-hydroxypropyl-beta-cyclodextrin may be an amount effective to increase a circulating and/or systemic amount of 24-hydroxycholesterol as compared to a baseline. In some cases, the level of circulating and/or systemic 24-hydroxycholesterol may be increased by at least about 10% as compared to a baseline (e.g., at 24 hours after treatment), for example, increased at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, or greater.

In a particular embodiment, the level of circulating and/or systemic 24-hydroxycholesterol may be increased to at least about 50 ng/mL. In another aspect, the level of circulating and/or systemic 24-hydroxycholesterol may be increased to at least about 40 ng per mg of total circulating and/or systemic cholesterol, for example, to at least about 50 ng per mg, to at least about 60 ng per mg, to at least about 70 ng per mg, to at least about 80 ng/mg, to at least about 90 ng per mg, or to at least about 100 ng per mg of total circulating and/or systemic cholesterol.

The subject may be less than 30 years old (e.g., less than 20 years old, less than 15 years old, less than 10 years old, or less than 5 years old). The subject can be diagnosed with atherosclerosis and/or atherosclerotic cardiovascular disease (e.g., CAD). The subject can be diagnosed with acute coronary syndrome (ACS) or chronic coronary syndrome (CCS) (e.g., as defined by the European Society of Cardiology). Atherosclerosis and/or atherosclerotic cardiovascular disease can be diagnosed via e.g., angiogram, cholesterol test, a computed tomography (CT) scan, Duplex scanning, an echocardiogram, an electrocardiogram (ECG or EKG), exercise stress test, an intravascular ultrasound, a magnetic resonance imaging (MRI) scan, a positron emission tomography (PET) scan, an optical coherence tomography (OCT) scan, a pharmacologic stress test, symptoms/medical history (e.g., patient-reported symptoms), fat attenuation index (FAI), or a combination thereof. The subject can have a symptom associated with atherosclerosis and/or atherosclerotic cardiovascular disease. The symptom associated with atherosclerosis and/or atherosclerotic cardiovascular disease can be chest pain (e.g., angina), shortness of breath, fatigue, confusion, muscle weakness, or a combination thereof. The subject can be at risk of developing atherosclerosis and/or atherosclerotic cardiovascular disease. A subject at risk of developing atherosclerosis and/or atherosclerotic cardiovascular disease can have at least one atherosclerosis risk factor. In some embodiments, atherosclerosis risk factors include, without limitation, being overweight or obese, high blood pressure, high cholesterol level, diabetes, lack of physical activity, one or more co-morbidities (e.g., smoking, renal disease, rheumatoid disease), and the use of chemotherapeutic agents.

The artery can be, e.g., a coronary artery, a cerebral artery, a peripheral artery, the aorta. The subject may have one or more atherosclerotic plaques having a high cholesterol and/or high lipid content (e.g., as measured by optical coherence tomography (OCT)). The subject may have one or more plaques having a low calcium score (e.g., as measured by a computed tomography (CT) scan). The subject may have stable or unstable CAD. The subject may have acute coronary syndrome (ACS) or chronic coronary syndrome (CCS) (e.g., as defined by the European Society of Cardiology). The subject may be treated (e.g., by the methods described herein) after (e.g., immediately after) having a myocardial infarction. The subject may have a thickening of the arterial wall (tunica media). The subject may be treated (e.g., by the methods described herein) after undergoing chemotherapy (e.g., the subject may have an increased risk of or may have developed atherosclerosis due to the use of chemotherapeutic agents).
The methods disclosed herein can be used to treat and/or prevent atherosclerotic cardiovascular disease. For example, the methods disclosed herein can be used to treat and/or prevent CAD, PAD, PVD, stroke, chronic kidney disease (CKD) caused by atherosclerosis, end-stage kidney disease (ESKD) caused by atherosclerosis, acute kidney failure caused by atherosclerosis, atherosclerotic renovascular disease (ARVD), renal artery stenosis, aortic aneurysm, idiopathic peripheral atrial hypertension, erectile dysfunction, intermittent claudication, and/or post-surgical or iatrogenic arterial disease. The methods disclosed herein can be used to treat and/or prevent atherosclerosis.
In some embodiments, the methods described herein causes a reduction in the size of atherosclerotic plaques (e.g., cholesterol-rich plaques and/or lipid-rich plaques) in the subject. The plaques may have a high cholesterol and/or high lipid content. The cholesterol and/or lipid content may be measured by, e.g., optical coherence tomography (OCT). The plaques may have a low calcium content. The plaques may have a low calcium score on a computed tomography (CT) scan.

Males and females with stable coronary artery disease participate in a randomized, double blind, single-center, placebo controlled studies. Safety (Phase 1b) and efficacy (Phase 2a) of 2-hydroxypropyl-beta-cyclodextrin to induce 27-hydroxycholesterol levels and epigenetic changes, after single (Phase 1b) and repeated dosing (Phase 2a) is assessed.
This randomized, double-blind, placebo-controlled trial is conducted at a single study center and has two parts.
Part A (Phase 1b) evaluates the safety and tolerability of 2-hydroxypropyl-beta-cyclodextrin, pharmacokinetics of 2-hydroxypropyl-beta-cyclodextrin, and explores the effects on biomarker endpoints in up to four sequential cohorts of CAD patients administered single-ascending IV doses of 2-hydroxypropyl-beta-cyclodextrin. After each cohort, safety and tolerability data is reviewed prior to further dose escalation in the next cohort. Dose escalation may continue up to the maximum well-tolerated dose, but does not exceed plasma 2-hydroxypropyl-beta-cyclodextrin exposures pre-specified in the study protocol.
Part B (Phase 2a) evaluates the safety and tolerability of 2-hydroxypropyl-beta-cyclodextrin, pharmacokinetics of 2-hydroxypropyl-beta-cyclodextrin, and effects on 27-hydroxycholesterol measured at 48 hours post-infusion as the primary biomarker endpoint in up to three sequential cohorts of CAD patients with escalating, multiple IV doses of 2-hydroxypropyl-beta-cyclodextrin, administered at intervals for up to four weeks. Doses and dose intervals for Part B are chosen based on preliminary safety and tolerability, and PK and biomarker (PD) results from Part A.
The dose levels in Part A are: Group A1: subjects are administered either 250 mg/kg 2-hydroxypropyl-beta-cyclodextrin or placebo; Group A2: subjects are administered either 500 mg/kg 2-hydroxypropyl-beta-cyclodextrin or placebo; Group A3: subjects are administered either 1,000 mg/kg 2-hydroxypropyl-beta-cyclodextrin or placebo; and Group A4: subjects are administered either 1,500 mg/kg 2-hydroxypropyl-beta-cyclodextrin or placebo.
In Part B, each Dose Group (Dose A; Dose B) enrolls a total of 24 subjects, including at least four of each gender. Each Dose Group is randomized to three Dose Frequency arms (qweek; q2weeks; qmonth). In each Dose Frequency arm, six subjects are randomized to 2-hydroxypropyl-beta-cyclodextrin and two subjects to placebo. Group 1: subjects are administered either 2-hydroxypropyl-beta-cyclodextrin or placebo, lx week, up to four doses; Group 2: subjects are administered either 2-hydroxypropyl-beta-cyclodextrin or placebo, lx every two weeks, up to four doses; and Group 3: subjects are administered either 2-hydroxypropyl-beta-cyclodextrin or placebo, lx month, up to four doses.
Primary Objectives
The primary endpoint determines the safety and tolerability of 2-hydroxypropyl-beta-cyclodextrin, administered as single and multiple IV doses.
Secondary Objectives
The secondary endpoint evaluates the single- and multiple-dose pharmacokinetics of 2-hydroxypropyl-beta-cyclodextrin.
Safety Endpoints
Safety endpoints include physical examinations, vital signs (e.g., blood pressure, heart rate, respiratory rate, temperature, body weight), 12-lead ECG, pulse oximetry spO2, routine clinical laboratory tests (e.g., hematology, chemistry, urinalysis), liver function test (eGFR), audiometry, and adverse events.
Pharmacodynamics Endpoints
Pharmacodynamics endpoints include cholesterol metabolites (e.g., 24-, 25-, 27-hydroxycholesterol) in blood and urine samples; cholesterol crystal dissolution capacity (CCDC) assay (ex vivo) in whole blood samples; plasma lipids (e.g., HDL-, LDL-cholesterol, total cholesterol, triglycerides) and ApoA1 levels; plasma myeloperoxidase (MPO) and fibrinogen; plasma markers of inflammation (e.g., IL-1B, IL-1a, IL-6, hsCRP) and/or plasma levels of anti-inflammatory cytokines (e.g., IL-1ra) and C3/C4 complement activity; gene expression (including LXR target genes), epigenomic assays, and phagocytosis assays (ex vivo) in isolated PBMCs; and flow-mediated dilatation (FMD) of brachial artery (e.g., non-invasive, quantitative ultrasound imaging method).
The efficacy and biological effects of HPCD treatment on specific organ and cell systems is also assessed by determining secondary endpoints. Secondary endpoints include: change in flow-mediated vasodilation (FMD) of the brachial artery, as assessed by ischemia-induced endothelium-dependent vasodilation after 7 days, using high-resolution ultrasonography; sterols/oxysterols (e.g. 24S- and 25-hydroxycholesterol levels in serum/plasma, urine, and stool); epigenomic data, ATAC sequencing of whole blood (PBMC); cholesterol crystal dissolution capacity (CCDC); change in gene expression of LXR-regulated genes in PMBCs; PBMC's phagocytic activity; MPO, fibrin; microbiome; pK of HPCD in serum, urine, stool; lipid levels (triglycerides, LDL-/HDL-cholesterol, ApoA1) in serum, urine, and stool; serum markers of inflammation and myocardial damage (IL-1β, IL-1a, IL-6, hsCRP, troponin, CK, CK-MB, and NT-pro-BNP); serum levels of anti-inflammatory cytokines (e.g., IL-1ra); complement activation; all-cause and cardiovascular mortality; myocardial infarction; major and minor stroke; and blood pressure (24 h registration).
A male human subject was treated with 2-hydroxypropyl-beta-cyclodextrin with single-ascending doses administered intravenously every 4 weeks according to Table 1 below.
For each dose, whole blood was collected pre-dose, post-dose (line flush), 1 hour post-dose, and 24 hours post-dose. Plasma was separated from the whole blood and subjected to a cholesterol crystal dissolution capacity (CCDC) assay using techniques similar to those described in the literature. The CCDC assay measures the ability of a sample to dissolve cholesterol crystals.
Blood plasma pre-dose was also incubated ex vivo with 2-hydroxypropyl-beta-cyclodextrin and the ability of the plasma to dissolve cholesterol crystals was measured.
Taken together, the data presented herein demonstrates that treatment with 2-hydroxypropyl-beta-cyclodextrin increases plasma cholesterol crystal dissolution capacity which may lead to dissolution of and/or clearance of atherosclerotic plaques. The data further demonstrates that treatment with 2-hydroxypropyl-beta-cyclodextrin may be a suitable treatment for atherosclerosis and/or atherosclerotic cardiovascular disease, as described herein.
In this Example, a male human subject was treated with 2-hydroxypropyl-beta-cyclodextrin as in Example 2, and plasma levels of 24S-hydroxycholesterol and 27-hydroxycholesterol were measured.
In this Example, a male human subject was treated with 2-hydroxypropyl-beta-cyclodextrin as in Example 2, and ABCA1 and ABCG1 mRNA levels were measured.
