Definitions
- Age-related macular degeneration affects about 14-24% of the people aged 65 to 74 and about 35% of the people over 75 around the world, and results in vision impairment or loss in the center of the visual field (the macula) because of damage to the retina. It is a major cause of vision loss and potentially blindness in people over 50 years of age.
- the two principal forms of AMD are atrophic (non-exudative or "dry”) AMD and neovascular (exudative or "wet”) AMD.
- Atrophic AMD is characterized by geographic atrophy (GA) at the center of the macula in the advanced stage of AMD, and vision can slowly deteriorate over many years due to loss of photoreceptors and development of GA.
- GA geographic atrophy
- Neovascular AMD is a more severe form of AMD and is characterized by neovascularization (e.g., choroidal neovascularization) in the advanced stage of AMD, which can rapidly lead to blindness.
- Neovascular AMD affects more than 30 million patients worldwide and is a leading cause of vision loss in people aged 60 years or older - if untreated, patients are likely to lose central vision in the affected eye within 24 months of disease onset.
- About 90% of AMD patients have the dry form, and about 10% develop neovascular AMD.
- the present disclosure provides apolipoprotein (apo) mimetics for the treatment of AMD and other eye diseases and disorders.
- an apoA-I mimetic and/or an apoE mimetic are administered to treat AMD or another eye disorder.
- the apoA-I mimetic comprises, or is, L-4F or D-4F.
- the apoE mimetic comprises, or is, AEM-28-14.
- One or more other therapeutic agents can be administered in combination with an apo mimetic to treat AMD or another eye disorder. The one or more other therapeutic agents can be selected to target different underlying factors of AMD or the other eye disorder.
- An apo mimetic optionally in conjunction with another therapeutic agent, can be administered to treat, e.g., AMD in different stages (including the early, intermediate and advanced stages) of AMD and for different phenotypcs of AMD (including geographic atrophy and neovascular AMD), and to prevent or slow the progression to the next stage of AMD.

- Age-related changes to the retina and the choroid of the eye which contribute to the development of age-related macular degeneration (AMD) include the loss of rod photoreceptors, the thinning of the choroid, and the accumulation of lipofuscin and reportedly components thereof (e.g., A2E [N-retiny lidene-N-retinyl-elhanolamine]) in the retinal pigment epithelium (RPE) as well as lipids in the sub-RPE basal lamina (sub-RPE-BL) space and the Bruch's membrane (BrM, which is part of the choroid).
- A2E N-retiny lidene-N-retinyl-elhanolamine
- BLinD and drusen are believed to develop from a lipid wall that forms on the BrM.
- the abnormal aggregates of material, combined with the loss of normal extracellular matrix (ECM) maintenance function partially mediated by altered ratios of matrix metalloproteinases [MMPs] and tissue inhibitors of MMPs [TIMPs]), result in alterations in the BrM, with consequent formation of BLinD and drusen.
- ECM extracellular matrix
- Drusen are extracellular deposits rich in lipids (e.g., esterifed cholesterol [EC] and phospholipids) and lipoprotein components (e.g., apolipoprotein B [apoB] and/or apoE) and form in the sub-RPE-BL space between the RPE-BL and the inner collagenous layer of the BrM, possibly as a result of RPE secretion of EC-rich very low-density lipoproteins (VLDLs) basolaterally.
- lipids e.g., esterifed cholesterol [EC] and phospholipids
- lipoprotein components e.g., apolipoprotein B [apoB] and/or apoE
- Esterified cholesterol and phospholipids accumulate in the BrM throughout adulthood and eventually aggregate as BLinD on the BrM or soft drusen in the sub-RPE-BL space of older eyes.
- Soft drusen and BLinD are two forms (a lump and a thin layer, respectively) of the same lesion containing lipoprotein-dcrived debris.
- EC-rich, apoB/apoE-containing lipoproteins secreted by RPE cells are retained by a BrM that progressively thickens with age, until an oily layer forms on the BrM, with oxidation of lipids or other modifications followed by fusion of individual lipoproteins over time to form BLinD.
- SDD subretinal drusenoid deposits
- UC unesterified cholesterol
- FIG 1 illustrates tissue layers involved in AMD pathology and the role of lipid accumulation in AMD pathogenesis.
- the BrM consists of three layers: the inner collagenous layer (ICL), the elastic layer (EL) and the outer collagenous layer (OCL).
- the RPE basal lamina (RPE-BL) is attached to the ICL of the BrM, and there is no space between the RPE-BL and the ICL (the sub-RPE-BL space is a "potential" space).
- RPE cells secrete lipoprotein particles (circles in Figure 1) basally, which are dispersed in the ICL and the OCL of the BrM (the left-most panel in Figure 1).
- pre-BLinD As more lipoprotein particles are secreted and accumulate over the years, they form pre-BLinD on the tightly packed ICL of the BrM (the second-from-left panel in Figure 1). Secretion and accumulation of more lipoprotein particles over the years result in aggregation of the lipoprotein particles to form BLinD (a layer) on the BrM ICL and soft drusen (lumps) (the two middle panels in Figure 1).
- the formation of pre-BLinD creates a space between the RPE-BL and the BrM ICL (sub-RPE-BL space), which increases with the formation of BLinD and soft drusen and with a greater amount of them.
- the accumulation of lipid deposits, BLinD and soft drusen elevates the RPE off the BrM ICL (the second-from-right panel in Figure 1), and if the elevation (the sub-RPE-BL space) is sufficiently large, the RPE-BL can become detached from the BrM ICL.
- the RPE-BL can become detached from the BrM ICL.
- drusenoid pigment epithelial detachment PED
- PED drusenoid pigment epithelial detachment
- RPE cells become increasingly removed from their source of nutrients and oxygen in the choriocapillaris.
- RPE cells on the top of drusen migrate anteriorly into the neurosensory retina to seek retinal vasculature, and the RPE layer breaks up as RPE cells die, resulting in atrophy of the RPE layer. Furthermore, the lipid barrier created by BLinD and soft drusen blocks the exchange of incoming nutrients (including vitamin A) and outgoing waste between the choriocapillaris and the RPE cells, which leads to RPE cell atrophy and then death. RPE cell atrophy and death also result in the atrophy and death of photoreceptors as the RPE cells can no longer shuttle nutrients to the photoreceptors.
- BLinD on the BrM and soft drusen in the sub-RPE-BL space are rich sources of lipids that can be oxidized to form highly anti-inflammatory, and thus pro-angiogenic, oxidized lipids such as oxidized phospholipids.
- the biomechanically fragile cleavage plane created by BLinD and soft drusen are vulnerable to ramification by new blood vessels emanating from the choroid, crossing the BrM, and infiltrating the sub-RPE-BL space in type 1 neovascularization (NV) and breaking through to the subretinal space in type 2 NV, which are described below.
- NV neovascularization
- Leakage of fluid from the neovessels into the sub-RPE-BL space in types 1 and 2 NV further contributes to the volume of the sub-RPE-BL space and the elevation of the RPE off the BrM, and thereby can cause PED.
- Chronic inflammatory responses to the changes described above include complement- mediated pathways, infiltration by circulating macrophages, and activation of inflammasomes and microglia.
- Activation of the complement cascade leads to activation of the central component 3 (C3) and initiation of the terminal pathway with the cleavage of component 5 (CS) into CSa and CSb.
- the terminal pathway results in the assembly of a membrane attack complex (MAC), e.g., in the basal RPE membrane, the BrM or the choriocapiUaiy endothelial cell membrane, by stepwise binding of C5b, C6, C7, C8 and polymerized C9 to form a pore in the lipid bilayer of the membrane.
- MAC membrane attack complex
- the MAC can lead to the dysfunction and death of the RPE, the BrM and/or the choriocapillary endothelium, with outer retinal atrophy ensuing.
- CSa elicits pro-angiogenic effects, and combined with calcification and fracture of the BrM, can contribute to NV, including choroidal NV (CNV).
- the early stage of AMD (which is atrophic AMD) is characterized by the presence of a few medium-size drusen and pigmentary abnormalities such as hyperpigmentation or hypopigmentation of the RPE.
- the intermediate stage of AMD (which is atrophic AMD) is characterized by the presence of at least one large druse, numerous medium-size drusen, hyperpigmentation or hypopigmentation of the RPE, and geographic atrophy (GA) that does not extend to the center of the macula (non-central [or para-central] GA).
- GA represents the absence of a continuous pigmented layer and the death of at least some portion of RPE cells. Non-central GA spares the fovea and thus preserves central vision.
- the advanced (late) stage of AMD that remains atrophic AMD is characterized by the presence of drusen and GA that extends to the center of the macula (central GA).
- Central GA includes macular atrophy. Central GA involves the fovea and thus results in significant loss of central vision and visual acuity. RPE below the retina atrophies, which causes vision loss through the death of photoreceptors. RPE atrophy can result from a large accumulation of drusen and/or BLinD that contributes to the death of the overlying RPE, when the drusen become thick and the RPE is far removed from the choriocapillaris.
- Drusen may include calcification in the form of hydroxy apatite, and may progress to complete calcification, at which stage RPE cells have died.
- the RPE-BL thickens in a stereotypic manner to form basal laminar deposits (BLamD); RPE cells hence reside on a thick layer of BLamD. Junctions between the normally hexagonal-shaped RPE cells may be perturbed, and individual RPE cells may round up, stack and migrate anteriorly into the neurosensory retina, where the RPE cells are farther from their supply of nutrients and oxy gen in the
- the advanced stage of AMD that becomes neovascular AMD is characterized by neovascularization and any of its potential sequelae, including leakage (e.g., of plasma), plasma lipid and lipoprotein deposition, sub-RPE-BL, subretinal and intraretinal fluid, hemorrhage, fibrin, fibrovascular scars and RPE detachment.
- leakage e.g., of plasma
- plasma lipid and lipoprotein deposition lipid and lipoprotein deposition
- sub-RPE-BL subretinal and intraretinal fluid
- hemorrhage e.g., fibrin
- fibrin e.g., fibrin, fibrovascular scars and RPE detachment.
- CNV new blood vessels grow up from the
- neovascularization There are three types of neovascularization (NV). Type 1 NV occurs in the sub-RPE-BL space, and new blood vessels emanate from the choroid under the macular region. Type 2 NV occurs in the subretinal space above the RPE, and new blood vessels emanate from the choroid and break through to the subretinal space. In types 1 and 2 NV, new blood vessels cross the BrM and may ramify in the pro-angiogenic cleavage plane created by soft drusen and BLinD.
- Type 3 NV spinal angiomatous proliferation occurs predominantly within the retina (intraretinal), but can also occur in the subretinal space, and new blood vessels emanate from the retina with possible anastomoses to the choroidal circulation.
- Type 3 NV is the most difficult subtype of NV to diagnose and has the most devastating consequences in terms of photoreceptor damage, but type 3 NV responds well to treatment with an anti-VEGF agent.
- a neovascular AMD patient can also have a mixture of subtypes of NV, including type 1 plus type 2, type 1 plus type 3, and type 2 plus type 3.
- NV neurodegenerative disease
- Another form of NV is polypoidal vasculopathy, which is of choroidal origin and is the most common form of NV among Asians, whose eyes generally have few drusen but may have BLinD.
- the RPE can become detached from the BrM in each subtype of NV. For instance, leakage of fluid from neovessels into the sub-RPE-BL space in type 1 NV can result in pigment epithelium detachment.
- the new blood vessels generated by NV are fragile, leading to leakage of fluid, blood and proteins below the macula. Leakage of blood into the subretinal space is particularly toxic to photoreceptors, and intraretinal fluid signifies a poor prognosis for vision. Bleeding and leaking from the new blood vessels, with subsequent fibrosis, can cause irreversible damage to the retina and rapid vision loss if left untreated.
- Modified lipids including peroxidized lipids, can be strongly pro-inflammatory and thus can be pro-angiogenic. Therefore, modification (including oxidation) of lipids can be an important step leading to the development of NV, including type 1 NV.
- the modified lipids linoleate hydroperoxide and 7-ketocholesterol can be present in and on die BrM and can stimulate NV.
- NV can be regarded as a wound-healing process following inflammation.
- age-related macular degeneration is a disease or disorder that has a variety of underlying factors.
- Three of the major factors of AMD are formation of lipid-rich deposits, inflammation and neovascularization in the retina, the subretinal space, the sub-RPE-BL space and the BrM.
- Formation of lipid-containing deposits is one of the initial major factors that leads to sequelae such as chronic inflammation, non-central and/or central geographic atrophy (GA) of the retina, neovascularization (including CNV) and ultimately central vision loss or legal blindness.
- G non-central and/or central geographic atrophy
- CNV central vision loss or legal blindness
- Lipid-scavenging apolipoprotein mimetics which also possess other beneficial properties such as anti-inflammatory, antioxidant and anti-angiogenic properties, can be used to treat AMD and complications thereof.
- Apolipoprotein peptide mimetics can effectively reduce the accumulation of lipid-rich deposits in the eye.
- Apolipoprotein (apo) mimetics can modulate (e.g., inhibit) the production of lipoproteins (e.g., VLDLs), modulate (e.g., inhibit) cellular uptake of plasma lipids (e.g., cholesterol) and lipoproteins (e.g., VLDLs), mediate the clearance or scavenging of lipids (e.g., cholesterol and oxidized lipids, such as oxysterols) and lipoproteins (e.g., VLDLs) and remnants thereof (e.g., low- density lipoproteins [LDLs] and chylomicron remnants), and inhibit the formation of lipid-containing lesions.
- lipoproteins e.g., VLDLs
- VLDLs low- density lipoproteins
- apoE mimetics increase lipid (e.g., cholesterol) efflux, mediate the clearance of lipids (e.g., cholesterol) and lipoproteins (e.g., VLDLs and chylomicrons), reduce cholesterol and triglyceride levels, decrease the formation of lipid-containing lesions, and possess antioxidant and anti-inflammatory properties.
- lipids e.g., cholesterol
- lipoproteins e.g., VLDLs and chylomicrons
- apoA-I mimetics promote lipid (e.g., cholesterol) efflux, reduce the formation of lipid-containing lesions (in the eye and arterial intima), and exhibit antioxidant and anti-inflammatory properties.
- apoA-V mimetics decrease VLDL-triglyceride (TG) production and stimulate lipoprotein lipase-mediated lipolysis of VLDL-TG.
- apoC-II mimetics increase lipid (e.g., cholesterol) efflux and activate lipoprotein lipase-mediated lipolysis of lipoproteins.
- a beneficial effect of increased lipoprotein lipase-mediated lipolysis of lipoproteins can be, e.g., reduced tissue availability of dietary-derived lipids, which may affect the upstream sources to RPE-derived lipoproteins that are secreted into the BrM, die sub-RPE-BL space and the subretinal space.
- apoA-I mimetics such as those described herein (e.g., L-4F and D-4F) can dissolve, mobilize and remove accumulated extracellular, and potentially intracellular, lipid deposits in the eye.
- L-4F and D-4F may be able to remove intracellular lipids via the LDL-receptor by forming pre-pHDL particles.
- Lipid deposits on the BrM form a lipid wall that acts as a diffusion barrier between the RPE and the choriocapillaris, promotes the formation of basal linear deposits (BLinD) and soft drusen, and is implicated in local inflammation and oxidative stress.
- ApoA-I mimetics can clear lipid deposits from the BrM, thereby remodeling the BrM structure to a normal or healthier state and restoring the BrM function, including reduced hydraulic resistivity and increased metabolite and micronutrient exchange between the choriocapillaris and the RPE, which improves RPE health.
- apoA-I mimetics e.g., L-4F
- apoA-I mimetics can reduce local inflammation and oxidative stress by, e.g., clearing lipid deposits from the BrM, BLinD and soft drusen.
- apoA-I mimetics e.g., L- 4F
- ApoA-I mimetics can also have high affinity for pro-inflammatory oxidized lipids and mediate their removal, adding to the high anti-inflammatory potential of the mimetics.
- the majority of AMD-associated lipid deposits are extracellular and accessible to lipid-clearing apoA-I mimetics.
- apoA-T mimetics can be used at any stage of AMD, including from early- to advanced-stage AMD, to treat an important upstream factor of AMD - accumulation of lipid deposits such as BlinD on the BrM and soft drusen in the sub-RPE-BL space - and, through the removal of such deposits, to inhibit or curtail downstream factors of AMD, such as local inflammation and oxidative stress.

- the apo mimetic includes, or is, L-4F having me structure When folded into the
- L-4F is an amphipathic ⁇ --helix that has opposing polar and hydrophobic faces and mimics apoA-I, the predominant apolipoprotein of HDL.
- the apoA-I mimetic 4F possesses anu-dyslipidemic properties.
- L-4F is capable of binding both oxidized lipids and unoxidized lipids with a greater affinity than apoA-I itself and reduces lipid deposits, e.g., in the sub-RPE-BL space and on the Bruch's membrane (BrM).
- L-4F is a potent lipid acceptor and scavenger that removes extracellular lipids (and potentially intracellular lipids), including neutral lipids, esterified cholesterol and phospholipids, from, e.g., the BrM and the sub-RPE-BL space, thereby improving, e.g., the BrM structure (e.g., reducing the thickness and normalizing the layer arrangement of the BrM) and the BrM function (e.g., decreasing hydraulic resistivity of the BrM and increasing metabolite and micronutrient exchange between the RPE and the choriocapillaris, including facilitating
- Extracellular age-related lipid deposits at, e.g., the BrM form a hydrophobic diffusion barrier that causes oxidative stress and inflammation in, e.g., the RPE and the retina, and removal of such lipid deposits by L-4F curtails such oxidative stress and inflammation.
- L-4F possesses additional beneficial properties. For instance, L-4F exhibits a strong antiinflammatory property, due in part to its high-affinity binding to pro-inflammatory oxidized lipids (e.g., oxidized phospholipids) and fatty acid hydroperoxides and its clearance of such oxidized lipids. L-4F can also enhance the ability of HDL-cholesterol to protect LDL-cholesterol from oxidation, thereby curtailing the formation of pro-inflammatory oxidized lipids. Furthermore, L-4F inhibits complement activation and reduces the levels of complement factor D and the membrane attack complex, which can be additional reasons for its antioxidant and anti-inflammatory properties and can result from its inhibition of downstream effects of lipid deposition.
- pro-inflammatory oxidized lipids e.g., oxidized phospholipids
- fatty acid hydroperoxides fatty acid hydroperoxides and its clearance of such oxidized lipids.
- L-4F can also enhance the ability of HDL-cholesterol to protect LDL-
- L-4F has anti- angiogenic property.
- Extracellular lipid-rich deposits in the sub-RPE-BL space provide a biomechanically fragile, pro-inflammatory milieu into which new blood vessels can enter and propagate, unimpeded by RPE basal lamina connections to the rest of the BrM. Removal of such lipid deposits by L-4F can close up or substantially reduce this pro-angiogenic cleavage plane.
- L-4F demonstrated an effective ability to scavenge neutral lipids and esterified cholesterol, to
- lipoproteins both native and modified in drusen are not bound to structural collagen and elastin fibrils, unlike lipoproteins in the BrM, the former are more loosely bound than the latter and hence are easier to remove. Therefore, the great reduction of esterified cholesterol and lipid deposits from the BrM in the macaque study demonstrates the ability of L-4F to effectively reduce soft drusen and scavenge lipids, including esterified cholesterol, from eye tissues, including the BrM. Although the RPE has active proteases, intravitreally injected L-4F readily crossed the RPE and reached the BrM, and effectively removed lipid deposits from the BrM in the macaque study.
- Removal of lipid deposits from the BrM by L-4F normalizes the structure and function of the BrM.
- reduction of drusen volume by L-4F can decrease elevation of the RPE layer off the BrM and thereby can reduce metamorphopsia, and can prevent, delay the onset of or slow the progression of non- central or central geographic atrophy and thereby can improve vision.
- Reduction of drusen volume in humans can be readily quantified using spectral domain optical coherence tomography (SDOCT) and commercially available software.
- SDOCT spectral domain optical coherence tomography
- L-4F can maintain or improve the health of the RPE and thereby can prevent or forestall RPE atrophy, including in non-central and central geographic atrophy.
- Soft drusen and drusenoid pigment epithelial detachments (PED) grow over time because RPE cells continue to secrete lipoproteins.
- the RPE layer over the drusen and drusenoid PED roughens over time, and RPE cells migrate out of the RPE layer and anteriorly into the neurosensory retina, preferentially over the apices, where the RPE cells are farther from the choriocapillaris and thus seek oxygen from the retinal circulation.
- L-4F can prevent the anterior migration of RPE cells and thereby can keep RPE cells sufficiently close to the choriocapillaris so that RPE cells are not energetically and metabolically decompensated and hence do not atrophy. Furthermore, removal of lipid deposits from the BrM improves the transport of incoming micronutrients (including vitamin A) and outgoing waste between the choriocapillaris and the RPE. By reducing drusen and removing lipid deposits from the BrM, L-4F can maintain RPE health and forestall RPE atrophy, and thereby can preserve photoreceptors and vision. Health of the RPE overlying drusen can be monitored by SDOCT of the macula.
- MAC membrane attack complexes
- C5b-9 is the final product of activation of the complement system, and builds up in the BrM-choriocapillaris complex during a person's lifespan, starting in childhood.
- L-4F can improve the health of the BrM and the choriocapillaris endothelium, and thereby can improve the blood supply to the outer retina and micronutricnt exchange between the choriocapillaris and the RPE and can promote the clearing of lipoprotein particles secreted by the RPE into the systemic circulation.
- L-4F can prevent or forestall neovascularization (NV). Basal linear deposits and soft drusen are major sources of potentially pro-inflammatory lipids in the sub-RPE-BL space where type 1 NV, the most common type of NV, occurs.
- L-4F can also scavenge any peroxidized lipids and other modified lipids formed.
- L-4F can prevent the migration of RPE cells away from the nutrient-transporting choriocapillaris and hence their secretion of distress-induced VEGF, a potent stimulus of NV.
- normalization of the BrM as a result of removal of lipid deposits from the BrM by L-4F suppresses choroidal NV by reinforcing the natural barrier between the choriocapillaris and the sub-RPE-BL space.
- L-4F can prevent or curtail NV, including type 1 NV, and can improve the treatment of neo vascular AMD, and reduce the treatment burden, with anti- angiogenic agents, including intravitreally injected anti-VEGF agents.

- the frequency of administration and the total number of administrations are per administered eye in certain embodiments and for both eyes in other embodiments, as the apo mimetic may also have a therapeutic effect in the fellow non-administered eye.
- the duration/length of treatment with the apolipoprotein mimetic can be adjusted if desired and can be selected by the treating physician to minimize treatment burden and to achieve desired outcome(s), such as reduction of lipid deposits to a desired level (e.g., the presence of a few medium-size drusen or the absence of any large druse) and elimination or reduction of geographic atrophy (non-central or central) to a desired level.
- desired level e.g., the presence of a few medium-size drusen or the absence of any large druse

- the apo mimetic e.g., an apoA-I mimetic (e.g., L-4F) and/or an apoE mimetic (e.g., AEM-28-14)] is administered at least in the early phase of intermediate AMD to prevent or delay the onset of non-central GA.
- Intermediate AMD is characterized by a substantial amount of confluent soft drusen, which can mainly comprise esterified cholesterol and phospholipids.
- Reduction of confluent soft drusen in intermediate AMD using the apo mimetic can result in decrease in the thickness ("thinning") and normalization of the Bruch's membrane, as well as renewal of the overlying RPE cell layer due to improved exchange of micronutrients and metabolites between the choriocapillaris and the RPE.
- Reduction of confluent soft drusen can be observed by non-invasive techniques such as spectral domain optical coherence tomography (SDOCT).
- SDOCT spectral domain optical coherence tomography
- the apo mimetic e.g., an apoA-I mimetic (e.g., L-4F) and/or an apoE mimetic (e.g., AEM-28-14)] is administered at least in the early stage of AMD.
- the apo mimetic can be administered at an earlier stage (e.g., the early stage or the intermediate stage) of AMD to slow or stop the progression of AMD.
- the apo mimetic [e.g., an apoA-I mimetic (e.g., L-4F) and/or an apoE mimetic (e.g., AEM-28-14)] is administered at least in the early stage of AMD to prevent or delay the onset of non-central GA.
- the apo mimetic is administered locally to, into, in or around the eye (e.g., by intravitreal, subconjunctival, subretinal or sub-Tenon's injection or eye drop) in the early stage of AMD.
- the apo mimetic e.g., an apoA-I mimetic (e.g., L-4F) and/or an apoE mimetic (e.g., AEM-28-14)
- the apo mimetic can be administered less frequently (e.g., an injection every about 3, 4 or 6 months), in a smaller total number of administrations (e.g., about 1, 2 or 3 injections) or in a higher dose per administration (e.g., about 0.5-1 mg or 1-1.5 mg per injection), or any combination or all thereof, to minimize the treatment burden.
- the apo mimetic does not need to eliminate or remove all or most of the abnormal lipid deposits from the eye to have a therapeutic or prophylactic effect in AMD. If a threshold amount of abnormal lipids is cleared from the eye, natural transport mechanisms, including traffic between the choriocapillaris endothelium and the RPE layer, can properly work again and can clear remaining abnormal lipids from the eye. Furthermore, lipids accumulate in the eye slowly over a period of years (although fluctuations in druse volume in a shorter time frame are detectable).
- apo mimetic can still have a therapeutic or prophylactic effect in early AMD.
- the apo mimetic e.g., an apoA-I mimetic (e.g., D-4F) and/or an apoE mimetic (e.g., AEM-28-14)
- a variant of the apo mimetic containing one or more, or all, D-amino acids can be administered systemically (or by eye drop, because the ocular surface contains peptidases/proteases).
- administration can be much higher than its dose for local administration (e.g., by intravitreal injection or eye drop) to take into account its systemic distribution and its potential systemic anti-dyslipidemic effects, such as reduction or removal of atherosclerotic plaques in the systemic vasculature, which may be a major target (and thus a sink) for the apo mimetic in systemic circulation.
- local administration e.g., by intravitreal injection or eye drop

- the apo mimetic e.g., an apoA-I mimetic (e.g., L-4F) and/or an apoE mimetic (e.g., AEM-28-14)
- the apo mimetic in intermediate AMD and advanced AMD (including atrophic AMD and neovascular AMD), can be administered by injection (e.g., intravitreal, subconjunctival, subretinal or sub-Tenon's injection) more frequently (e.g., once every about 4-12 or 4-8 weeks in intermediate AMD, and once every about 4-8 or 4-6 weeks in advanced AMD), in a greater total number of injections (e.g., about 4-8 injections or more in intermediate AMD, and about 8-12 injections or more in advanced AMD), in a higher dose per injection (e.g., up to about 1-1.5 mg per injection), or in a larger total dose for the entire treatment regimen (e.g., up to about 10-15 mg or more in intermediate AMD, and up to about 15-20 mg or more in advanced AMD), or any combination or all thereof, to remove a greater amount of lipid deposits, including drusen and basal linear deposits, from the eye, including from the sub-RPE-BL space and the Bruch'
- treatment is expected to keep stable, or to improve, photopic (daylight) vision mediated by cone photoreceptors and scotopic (night) vision mediated by rod photoreceptors.
- the health of RPE cells can be assessed with qAF, where stability of or increase in qAF intensity can indicate stable or improved RPE health, as a reduction in qAF intensity can signify degeneration of RPE cells.
- qAF can be used to quantify the area or size of geographic atrophy, and hence to monitor the progression of non-central GA or central GA, as was done in the MAHALO Phase II study on lampalizumab.
- RPE cells can also be assessed with SDOCT, where the presence of hyper-reflective foci located vertically above drusen within the retina indicates migratory RPE cells, which signifies that the RPE layer is about to disintegrate just before atrophy of RPE cells and photoreceptors. Poor RPE health can be an indicator of poor visual outcome in atrophic AMD and neovascular AMD.
- OCT-FA can detect the presence of sub- RPE-BL, subretinal or intraretinal fluid, which can signify active neovascularization and leakage of fluid from new blood vessels.
- an apo mimetic e.g., an apoA-I mimetic (e.g., L-4F) and/or an apoE mimetic (e.g., AEM-28-14)
- injection e.g., intravitreal, subconjunctival, subretinal or sub-Tenon's injection
- the apo mimetic can be administered in a certain frequency of injections and in a certain dose per injection.
- the apo mimetic can be injected less frequently and/or in a lower dose per injection, or the apo mimetic can be injected less frequently and in a higher dose per injection so that a substantially similar total dose is administered over a certain time period.
- one or more diagnostic methods show a worsening of the disease, or no change in the disease (particularly in a more severe form of the disease, such as non-central or central geographic atrophy or neovascular AMD) after the initial phase of treatment (e.g., SDOCT shows an increase in soft drusen volume, or no change in soft drusen volume after the initial phase of treatment), the apo mimetic can be injected more frequently and/or in a higher dose per injection. If one or more diagnostic methods show stark improvement in the disease (e.g., SDOCT shows elimination of all or most soft drusen), treatment with the apo mimetic can be paused or stopped.
- treatment with the apo mimetic such as the treatment regimen that had resulted in the stark improvement
- SDOCT shows an appreciable or significant amount of soft drusen
- treatment with the apo mimetic such as the treatment regimen that had resulted in the stark improvement
- the progression and treatment of AMD can be monitored using diagnostic methods to adjust the treatment accordingly.
- Such a treatment regimen can be called an "as-needed" or "pro re nata” regimen.
- An as-needed regimen involves routine clinic visits (e.g., once every 4, 6 or 8 weeks) so that one or more diagnostic methods can be performed to monitor the progression and treatment of AMD, although the therapeutic agent might not be administered during a clinic visit depending on the results of the diagnostic tests.
- an apo mimetic e.g., an apoA-I mimetic (e.g., L-4F) and/or an apoE mimetic (e.g., AEM-28-14)] administered by injection (e.g., intravitreal, subconjunctival, subretinal or sub-Tenon's injection
- the apo mimetic can be administered in a certain frequency of injections (e.g., once monthly) and in a certain dose per injection during the initial phase of treatment.
- the apo mimetic can be injected less frequently (e.g., once every 6 or 8 weeks), and in the same dose per injection as the initial dose per injection or in a higher dose per injection so that a substantially similar total dose is administered over a certain time period.
- the second phase of treatment can last for a selected period of time.
- the apo mimetic can be injected even less frequently (e.g., once every 10 or 12 weeks), and in the same dose per injection as the initial dose per injection or in a higher dose per injection so that a substantially similar total dose is administered over a certain time period.
- the optional third phase of treatment can last for a selected period of time. And so on.
- Such a treatment regimen can be called a "treat-and-extend" regimen.
- one or more diagnostic methods can be performed to monitor the progression and treatment of AMD and possibly to adjust the treatment depending on the results of the diagnostic tests. For example, if one or more diagnostic methods show a worsening of the disease (e.g., SDOCT shows an increase in soft drusen volume), the apo mimetic can be injected more frequently and/or in a higher dose per injection.
- the apo mimetic can be injected less frequently and/or in a lower dose per injection, or the apo mimetic can be injected less frequently and in a higher dose per injection so that a substantially similar total dose is administered over a certain time period.
- a treat-and-extend regimen does not involve routine diagnostic visits, but the therapeutic agent is administered in routine treatment visits (whose frequency decreases in the second phase and the optional third phase of treatment), even though the therapeutic agent, or the dose administered, might not be medically needed at that time.
- a potential advantage of a treat-and-extend regimen over an as-needed regimen is that it can decrease the total number of clinic visits made for monitoring and treatment.

- a maximal effect such as substantially complete resolution of subretinal fluid and/or intraretinal fluid without new retinal hemorrhage, or no further reduction of subretinal fluid and/or intraretinal fluid in OCT-FA for at least two consecutive clinic visits in the absence of new retinal hemorrhage.
- the anti-angiogenic agent can be injected less frequently (the interval between injections can be extended by, e.g., about 2 or 4 weeks). If the disease remains stable, the interval between injections can be extended by, e.g., about 2 or 4 weeks at a time, and the total extension period can be up to, e.g., about 3, 4, 5 or 6 months. If the patient shows a relatively mild deterioration in the disease (e.g., reappearance of a relatively small amount of subretinal fluid and/or intraretinal fluid or a relatively small increase in the amount thereof), the interval between injections of the anti-angiogenic agent can be shortened by, e.g., about 1 or 2 weeks.

- a smaller gauge e.g., smaller than 30G
- excipients inhibit peptide/protein aggregation and increase peptide/protein solubility, for example, they can be employed to increase the concentration of a peptide or protein in a solution or suspension.
- Increased peptide/protein concentration decreases the volume needed to administer a given amount of the peptide or protein, which can have beneficial effects such as reduced ocular pressure if the peptide or protein is administered by injection into the eye.
- increased peptide/protein concentration allows a greater dose of the peptide or protein to be administered for a given volume, which can permit the peptide or protein to be administered less frequently for a given total dose administered over a time period.
- Less frequent administration (e.g., by intravitreal injection) of the peptide or protein can have benefits, such as improved patient compliance and health due to fewer invasive procedures being performed.
- the apo mimetic [e.g., an apoA-I mimetic (e.g., L-4F) and/or an apoE mimetic (e.g., AEM- 28-14)] can be used alone or in combination with one or more other therapeutic agents to treat AMD.
- other therapeutic agents include without limitation those described elsewhere herein.

- an apo mimetic e.g., an apoA-I mimetic [e.g., L-4F] and/or an apoE mimetic [e.g., AEM-28-14]
- One or more other therapeutic agents can optionally be administered.
- the vision impairment or loss can be associated with atrophic AMD (including non-central and/or central geographic atrophy) or neovascular AMD (including types 1, 2 and/or 3 neovascularization).
- AMD has a variety of underlying factors, including formation of lipid- containing deposits, formation of toxic byproducts, oxidation, inflammation, neovascularization and cell death.
- a plurality of therapeutic agents targeting multiple underlying factors of AMD, or having different mechanisms of action, can be utilized for the treatment of AMD.
- Therapeutic agents that can be used, optionally in combination with apolipoprotein mimetics, to treat AMD include without limitation:

- a therapeutic agent can be administered in the same formulation or in separate formulations as the other therapeutic agent.
- lipid-rich deposits is an important upstream cause of AMD that leads to complications such as non-central and central geographic atrophy and neovascularization.
- One multi- pronged approach to preventing or minimizing the accumulation of lipid-rich material is to inhibit the production of lipids (e.g., cholesterol and fatty acids) and lipoproteins (e.g., VLDLs) by RPE cells, to inhibit the uptake of plasma lipids (e.g., cholesterol and fatty acids) and lipoproteins (e.g., VLDLs) by RPE cells, to inhibit the secretion of lipids (e.g., cholesterol and fatty acids) and lipoproteins (e.g., VLDLs) and components thereof (e.g., apoB and apoE) by RPE cells into the BrM, the sub-RPE-BL space and the subretinal space, and to clear lipids (e.g., cholesterol and oxidized lipids) and lipoproteins (e
- apoB is involved in the formation of at least hepatic VLDL, which is the parent of at least plasma LDL.
- Inhibition of apoB production by RPE cells and inhibition of the uptake by RPE cells of fatty acids available to lipidate apoB could curtail the production of VLDLs, and hence possibly LDLs, by RPE cells.
- Anti-dy slipidemic agents modulate inter alia the production, uptake and clearance of lipids, lipoproteins and other substances that play a role in the formation of lipid-containing deposits in the retina, the subretinal space, the sub-RPE-BL space, and the choroid (e.g., the BrM).
- One class of anti- dyslipidemic agents is fibrates, which activate peroxisome proliferator-activated receptor-alpha (PPAR-a).
- Fibrates are hypolipidemic agents that reduce fatty acid and triglyceride production, induce lipoprotein lipolysis but stimulate the production of high-density lipoprotein (HDL, which mediates reverse cholesterol transport), increase LDL removal from plasma, and stimulate reverse cholesterol transport from cells to the circulation and ultimately the liver, where cholesterol is metabolized and excreted into the bile.
- HDL high-density lipoprotein
- Choesterol can also be cleared through, e.g., the removal of HDL-cholesteryl ester by the gut.
- fibrates include without limitation bezafibrate, ciprofibrate, clinofibrate, clofibric acid, clofibrate, aluminum clofibrate, clofibride, etofibrate. fenofibrate, gemfibrozil, ronifibrate, simfibrate, and analogs, derivatives and salts thereof.
- Other hypotriglyceridemic agents include omega-3 fatly acids, such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
- statins HMG-CoA reductase inhibitors
- Statins inhibit cholesterol synthesis, decrease the production of VLDL and LDL apoB (or the production of apoB-containing VLDLs and LDLs), reduce apoB secretion, and lower the level of plasma lipids.
- statins include, but are not limited to, atorvastatin, cerivastatin, fluvastatin, mevastatin, monacolins (e.g., monacolin K [lovastatin]), pitavastatin, pravastatin, rosuvastatin, simvastatin, and analogs, derivatives and salts thereof.
- ACC inhibitors inhibit fatty acid and triglyceride (TG) synthesis and decrease VLDL-TG secretion.
- Non- limiting examples of ACC inhibitors include anthocyanins, avenaciolides, benzodioxepines ⁇ e.g., 7- (4-propyloxy-phenylethyn>'l)-3,3-dimethyl-3,4 dihydro-2H-benzo[b] [l,4]dioxepine ⁇ ,

- Acyl-CoA cholesterol acyltransferase (ACAT) inhibitors can also be used as anti- dyslipidemic agents.
- ACAT inhibitors inhibit cholesterol esterification and decrease the production of VLDL and LDL apoB (or the production of apoB-containing VLDLs and LDLs).
- Examples of ACAT inhibitors include without limitation avasimibe, pactimibe, pellitorine, terpendole C, and analogs, derivatives and salts thereof.
- GLP-1 receptor agonists reduce the production of apoB and VLDL particles and hence VLDL-apoB and VLDL-TG, decrease the cellular content of cholesterol and triglycerides, and reduce or reverse hepatic steatosis (fatty liver) by decreasing hepatic lipogenesis.
- Non-limiting examples of GLP-1 receptor agonists include exendin-4, albiglutide, dulaglutide, exenatide, liraglutide, lixisenatide, semaglutide, taspoglutide, CNT0736, CNT03649, and analogs, derivatives and salts thereof. Because GLP-1, the endogenous ligand of the GLP-1 receptor, is rapidly degraded by dipeptidyl peptidase 4 (DPP-4), anti-dyslipidemic effects similar to those of GLP-1 receptor agonists can be achieved with the use of a DPP-4 inhibitor, albeit with potentially lower potency.
- DPP-4 inhibitors include alogliptin, anagliptin, dutogliptin, gemigliptin.
- linagliptin saxagliptin, sitagliptin, teneligliptin, vildagliptin, berberine, lupeol, and analogs, derivatives and salts thereof.
- Additional anti-dyslipidemic agents include inhibitors of the microsomal triglyceride transfer protein (MTTP), which is expressed in RPE cells.

- MMPs Matrix metalloproteinases degrade extracellular matrix (ECM) proteins and play an important role in cell migration (dispersion and adhesion), cell proliferation, cell differentiation, angiogenesis and apoptosis.
- ECM extracellular matrix
- apoptosis For example, as AMD progresses to the advanced stage, elevated levels of MMPs can degrade the Bruch's membrane (BrM), an ECM and part of the choroid. Endothelial cells migrate along the ECM to the site of injury, proliferate, form endothelial tubes, and mature into new blood vessels that arise from capillaries in the choroid and grow through the fractured BrM.
- Bruch's membrane Bruch's membrane
- neovascularization including CNV
- neo vascular AMD can also cleave peptide bonds of cell-surface receptors, releasing pro-apoptotic ligands such as FAS.

- an MMP activator rather than an MMP inhibitor may be desired.
- the BrM undergoes constant turnover, mediated by MMPs and TIMPs.
- the BrM thickens progressively with age, partly because of increased levels of TIMPs and a resulting reduction in ECM turnover. Thickening of ECM in the BrM with age may result in the BrM's retention of lipoproteins secreted by the RPE, eventually leading to the formation of BLinD and drusen.
- the accumulation of lipid-rich BLinD and basal laminar deposits (BlamD, which are excess extracellular matrix in thickened RPE-BL) lengthen the diffusion distance between the choriocapillaris and the RPE.
- An MMP activator can be used to achieve greater BrM turnover and less thickening of the BrM, but not to the point where the BrM becomes so degraded that new blood vessels can grow through the BrM.
- MMP activators include without limitation basigin (extracellular matrix

- Neovascular AMD is the underlying mechanism of neovascularization (including types 1 , 2 and 3), which can occur in the advanced stage of AMD to lead to neovascular AMD and severe vision loss if left untreated.
- Neovascular AMD is characterized by vascular growth and fluid leakage in the choroid, the sub-RPE-BL space, the subretinal space and the neural retina. Leakage from blood vessels can be more responsible for vision loss associated with neovascular AMD than growth of new blood vessels.
- VEGFs vascular endothelial growth factors
- VEGFs are potent, secreted endothelial-cell mitogens that stimulate the migration and proliferation of endothelial cells, and increase the permeability of new blood vessels, resulting in leakage of fluid, blood and proteins from them.
- VEGFs increase the level of MMPs, which degrade the ECM further.
- VEGFs enhance the inflammatory response.
- VEGFs or receptors therefor are not the only potential targets for anti-angiogenic agents. For example, targeting integrins associated with receptor tyrosine kinases using an integrin inhibitor (e.g., ALG-1001) inhibits the production and growth of new blood vessels and reduces the permeability (leakage) of blood vessels.
- an integrin inhibitor e.g., ALG-1001
- Angiogenesis can also be inhibited through inhibition of other targets, including without limitation kinases (e.g., tyrosine kinases, such as receptor tyrosine kinases) and phosphatases (e.g., tyrosine phosphatases, such as receptor tyrosine phosphatases).
- kinases e.g., tyrosine kinases, such as receptor tyrosine kinases
- phosphatases e.g., tyrosine phosphatases, such as receptor tyrosine phosphatases.

- the two or more anti-angiogenic agents comprise an anti-VEGF/VEGFR agent and an anti-PDGF/PDGFR agent, such as bevacizumab or ranibizumab and E10030, or aflibercept and REGN2176-3.
- E10030 blocks PDGF-B from binding to its natural receptor on pericytes, causing pericytes to be stripped from newly formed abnormal blood vessels. Left unprotected, the endothelial cells are highly vulnerable to the effects of an anti-VEGF agent. Because of this ability to strip pericytes, El 0030 may have an effect on both immature blood vessels and more mature blood vessels slightly later in the disease process.

- Laser surgery can also be employed to destroy abnormal blood vessels in the eye and generally is suitable if the growth of abnormal blood vessels is not too extensive and the abnormal blood vessels are not close to the fovea.
- PDT utilizes a laser in combination with a compound (e.g., verteporfin) that, upon activation by light of a particular wavelength, injures target cells and not normal cells.

- RPE cells may atrophy and die as a result of rampant lipid deposition in the sub-RPE-BL space and over the BrM.
- an advanced-stage AMD patient can first be treated with a lipid-clearing apo mimetic [e.g., an apoA-I mimetic (e.g., L-4F) and/or an apoE mimetic (e.g., AEM-28-14)] and then receive RPE cell replacement (e.g., via one or more injections into or implantations in, e.g., die space below the retina).

- the choriocapillaris endothelium can be replaced with stem cell-derived choriocapillaris endothelial cells.
- Choriocapillaris vascular dropout/loss and reduced choroidal blood flow can occur early in the pathogenesis of AMD.
- the vascular density of the choriocapillaris is inversely correlated with the density of sub-RPE-BL deposits (e.g., drusen and BLinD), and the number of "ghost" vessels (remnants of previously healthy capillaries) is positively correlated with sub-RPE-BL deposit density.
- Vascular endothelial-cell loss may result from activation of the complement system and formation of MACs in the choriocapillaris, which can be inhibited by the use of a complement inhibitor (e.g., an inhibitor of MAC formation, deposition or function).
- a complement inhibitor e.g., an inhibitor of MAC formation, deposition or function
- Endothelial dysfunction may also be caused by : 1) a diminished amount of nitric oxide, which can be due to a high level of dimethylarginine (which interferes with L-arginine-stimulated nitric oxide synthesis) and can be corrected by the use of an agent that increases the level of nitric oxide (e.g., a stimulator of nitric oxide synthesis or an inhibitor of dimethylarginine formation; 2) an increase in reactive oxygen species, which can impair nitric oxide synthesis and activity and can be inhibited by the use of an antioxidant (e.g., a scavenger of reactive oxygen species); and 3) inflammatory events, which can be inhibited by an agent that inhibits endothelial inflammatory events (e.g., an apoA-I mimetic such as Rev-D-4F).

- Anecortave acetate can be administered once every 6 months using this delivery method, compared to monthly or bimonthly intravitreal injections of ranibizumab or aflibercept, respectively.
- the posterior juxtascleral depot method greatly decreases the risk of intraocular infection, endophthalmitis and detachment of the retina.
- a therapeutic agent may be desired in certain circumstances.
- oral administration of a therapeutic agent can increase patient compliance due to ease of use and non- invasiveness if, e.g., a topical formulation for local delivery (e.g., eye drop or contact lens) cannot be developed for mat therapeutic agent
- a pathological event of AMD may have a non-local component.
- the amount of lipid-containing material RPE cells secrete into the BrM, the sub-RPE-BL space and the subretinal space may be affected in part by the uptake of plasma lipids (e.g., cholesterol and fatty acids) and lipoproteins (e.g., LDLs) by RPE cells.

- AVA-101 comprises an adeno-associated virus 2 (AAV2) vector containing a gene that encodes soluble VEGFR 1 (FLT-1).
- AVA-101 Local administration of AVA-101 into the eye (e.g., the RPE or choriocapillary endothelium) results in expression of soluble VEGFR 1 by the host retinal cells.
- the soluble VEGFR 1 protein binds to VEGF in the extracellular space, which prevents VEGF from binding to membrane-bound VEGFRs and thereby inhibits angiogenesis.
- AVA- 101 can be administered as, e.g., a single subretinal injection for the treatment of, e.g., neovascular AMD (including types 1, 2 and/or 3 neovascularization), which precludes the need for multiple or frequent injections.

- the capsule and the scaffold maintain the cells (e.g., growth support and delivery of nutrients).
- the encapsulated cell-based drug-delivery system e.g., via access through the sclera
- the NTC-201 cells produce and secrete CNTF through the semipermeable capsule.
- Such an encapsulated cell technology e.g., NT-501 provides a controlled, continuous and sustained delivery of CNTF, and prolongs the half-life of CNTF from about 1-3 min to about 20-50 months.
- Intraocular delivery of CNTF using such an encapsulated cell technology can, e.g., reduce photoreceptor loss associated with the degeneration of cells of the retina, and hence can be used to treat, e.g., geographic atrophy.
- One or more polypeptide therapeutic agents can also be delivered via administration of naturally occuring cells that produce and release such agents.
- cells derived from umbilical cord tissue can rescue photoreceptors and visual functions, reportedly through the production and release of neuroprotectors such as neurotrophic factors.
- the therapeutically effective amount and the frequency of administration of, and the duration of treatment with, a particular therapeutic agent for the treatment of AMD or another eye disorder may depend on various factors, including the eye disease, the severity of the disease, the mode of administration, the age, body weight, general health, gender and diet of the subject, and the response of the subject to the treatment, and can be determined by the treating physician.
- the dosing regimen of one or more, or all, of the therapeutic agcnt(s) comprises one or more loading doses followed by one or more maintenance doses.

- a hydrogel can be locally administered to the eye by, e.g., eye drop, injection or implantation.
- the polymer chains of the cellulosic polymer and the polystyrene nanoparticles can form relaxed bonds under pressure, which allows the hydrogel to flow readily when pushed through a needle, but can form solidified bonds within seconds of release of the pressure, which allows the hydrogel to transform into a drug-carrying capsule in the eye.
- the hydrogel is loaded with a peptide or protein, such as an apolipoprotein mimetic or an anti-VEGF/VEGFR agent.
- a peptide or protein such as an apolipoprotein mimetic or an anti-VEGF/VEGFR agent.
- the peptide or protein can be released from the hydrogel as the edges of the hydrogel are gradually eroded by exposure to water in the eye, which allows the peptide or protein to be released from the hydrogel over the course of months and possibly years.

- the formulations can form spherical depots in an aqueous medium (e.g., a buffer) and release the peptide/protein for an extended period (e.g., about 1, 2, 3, 4, 5 or 6 months).
- the release rate of the peptide/protein can be influenced by the polymer viscosity based on the polymer MW, and by the drug loading to a lesser extent, which permits fine- tuning of the drug-release profile.
- the peptide/protein can maintain its structure when incorporated into the polymer matrix, and can maintain its biological activity (e.g., high affinity for its biological target) after being released from the polymer matrix.
- a solid therapeutic agent can be administered in the form of microparticles comprising primarily or consisting essentially of the therapeutic agent.
- the agent in the form of such microparticles would substantially completely dissolve over time after administration, and thereby would have a longer duration of action and require fewer administrations (e.g., injections).
- such microparticles may form a depot for prolonged delivery of the therapeutic agent.
- Such microparticles can optionally contain a relatively small amount of one or more excipients.
- Microparticles comprising primarily or consisting essentially of a therapeutic agent can be administered locally by, e.g, injection (e.g., intravitreal, subconjunctival, subretinal or sub-Tenon's injection), eye drop or implant (e.g., intravitreal, subretinal or sub-Tenon's implant).

- An impermeable member is positioned at the inner tube's first end and prevents passage of the drug out of the inner drug core through the inner tube's first end.
- a permeable member is positioned at the inner tube's second end and allows diffusion of the drug out of the inner drug core through the inner tube's second end.
- Guo's sustained-release system can be applied by injection or implantation to the vitreous humor, under the retina or onto the sclera, for example.

- Figure 2 shows the scoring of staining of neutral lipids in and on the Bruch's membrane with oil red O (ORO) in the injected eye and the fellow non-injected eye of macaques receiving 6 monthly intravitreal injections of L-4F or placebo (scrambled L-4F).

- Figure 5 shows the intensity of staining of complement factor D in the injected eye and the fellow non-injected eye of macaques receiving 6 monthly intravitreal injections of L-4F or placebo (scrambled L-4F).
- Lipid deposition in the Bruch's membrane contributes to thickening of the BrM.
- Bruch's membrane thickness was measured at the temporal outer macula of enucleated eyes examined by electron microscopy post-mortem. Eyes injected with L-4F exhibited reduction of BrM thickness (1.31 um ⁇ SE 0.11) by about 24% compared to eyes injected with placebo (1.73 um ⁇ SE 0.02).
- Figure 6 shows the thickness of the Bruch's membrane measured at the temporal outer macula in the injected eye and the fellow non-injected eye of macaques receiving 6 monthly intravitreal injections of L-4F or placebo (scrambled L-4F).
- L-4F had similar effects on the fellow non-injected eye as on the injected eye after 6 monthly intravitreal injections (see Figures 2-6). Without intending to be bound by theory, L-4F intravitreally injected into one eye reached the BrM and from there could have entered the choriocapillaris and hence systemic circulation and ultimately the fellow non-injected eye. Also without intending to be bound by theory, the magnitude of L-4F's therapeutic effects in the fellow non-injected eye could have been due in part to the relatively small body weight of the macaques relative to eye size and the primarily vegetarian diet of the macaques, which exhibited no atherosclerosis, a potential target for L-4F in systemic circulation.
- L-4F was well tolerated in all of the macaques, as none of the macaques intravitreally injected with L-4F experienced any significant adverse event or side effect. For example, 6 monthly intravitreal injections of L-4F did not increase the blood level of high-sensitivity C-reactive protein (hsCRP) compared to the blood level of hsCRP on the day prior to the first injection of L-4F.
- hsCRP high-sensitivity C-reactive protein
- Circulating hsCRP which is mainly produced in the liver, is a non-specific marker for systemic inflammation.
- the apoA-I mimetic L-4F functioned as an effective lipid scavenger and removed lipid deposits from the BrM in a monkey model of age-related maculopathy. Removal of lipid deposits from the BrM restored BrM integrity as examined by electron microscopy. In addition, downstream effects of lipid deposition such as local inflammation were reduced, as demonstrated by the marked reduction of complement activation in eyes injected with L-4F.
- Randomized, open-label, dose-escalation Phase I/il studies are conducted to evaluate the safety, tolerability, pharmacokinetics and effective dose of L-4F or a variant (e.g., D-4F) or a salt (e.g., acetate salt) thereof administered (e.g., by intravitreal injection) to patients with AMD (e.g., intermediate-stage AMD).
