A Phase 2b Study of FovistaTM, a Platelet Derived
Growth Factor (PDGF) Inhibitor in Combination with a Vascular Endothelial Growth
Factor (VEGF) Inhibitor for Neovascular Age-Related Macular Degeneration (AMD) |
| |
 |

|
| |
Purpose/Methods: To assess
the safety and efficacy of FovistaTM in combination with ranibizumab
compared to ranibizumab monotherapy, 449 patients with neovascular AMD were
randomized in a prospective, controlled, superiority trial to receive one of
the following treatment regimens administered every 4 weeks for 24 weeks:
FovistaTM 0.3 mg in combination with ranibizumab 0.5 mg; FovistaTM 1.5 mg in
combination with ranibizumab 0.5 mg; or sham in combination with ranibizumab
0.5 mg.
Results: The combination of FovistaTM (1.5 mg) with ranibizumab met the
pre-specified primary endpoint of superiority in mean visual acuity gain
compared to ranibizumab monotherapy (10.6 ETDRS letters at week 24, compared
to 6.5 letters, p=0.019). An additional 62% benefit from baseline was noted
in the FovistaTM (1.5 mg) combination therapy arm over ranibizumab
monotherapy. A classic dose-response curve was observed. Enhanced visual
outcomes for FovistaTM 1.5 mg combination therapy compared to ranibizumab
monotherapy were present at every monthly timepoint. The relative magnitude
of visual benefit increased over time, implying a benefit to continued
combination therapy. The superiority of FovistaTM 1.5 mg combination therapy
over ranibizumab monotherapy was consistent across all subgroups including
those analyzing baseline vision, lesion size, and central retinal thickness.
FovistaTM 1.5 mg combination was superior to ranibizumab monotherapy across
multiple treatment endpoints including 3, 4 and 5 lines of vision gain (ETDRS
chart). OCT and fluorescein angiography analysis showed patients receiving
FovistaTM 1.5 mg combination therapy had greater reduction in neovascular
size compared to those receiving ranibizumab monotherapy. No significant
safety issues were observed for either treatment group in the trial. |

Lipoprotein-associated Phospholipase A2 Inhibition
Regulates Retinal Vasopermeability During Experimental Diabetes |
| |
 |
Peter Adamson
Vice President and Head of Research, GSK Ophthalmology
GlaxoSmithKline
|
| |
|
| |
Diabetic macular edema is
recognized to have an inflammation-linked etiology. It is hypothesized that
inhibition of lipoprotein-associated phospholipase A2 (Lp-PLA2) is protective
against hyperglycemia-related compromise of the blood retinal barrier (BRB).
Lp-PLA2 was localized to the vascular endothelium of human retinal
capillaries,and in parallel, brown Norwegian rats had diabetes induced and
maintained for 4 weeks with treatment using vehicle or SB435495 (a specific
inhibitor of Lp-PLA2). A different group of hyperglycemic animals were
maintained treatment free for 4 weeks prior to initiating the 4 wk treatment
regimen with SB435495. A group of non-diabetic BN rats were used as controls.
BRB function was determined by retinal fluorescein angiography, Evan’s blue (EB)
leakage and immunohistochemical detection of intravascular and extravasated rat
albumin in the retina.
SB435495-treatment during initiation of diabetes resulted in less vascular leak
when compared to the vehicle-treated diabetic controls. EB leakage was elevated
in the vehicle-treated diabetic group when compared to non-diabetic
counterparts. 4 weeks treatment with SB435495 significantly prevented this
response after either 4 or 8 weeks of prior diabetes. In vehicle-treated
diabetic rats, albumin immunoreactivity was apparent in the retina from both
superficial and deep capillary plexi. In SB435495-treated diabetic rats, albumin
was co-localized with blood vessels with a pattern similar to non-diabetic
controls.
This data indicates that inhibition of Lp-PLA2 in a preclinical model of
hyperglycemia induced retinal vascular leak can prevent breakdown of the inner
BRB. Lp-PLA2 may thus be a useful target for treatment of DME.

Intrinsic Lipid Circuits: Key Regulators of Innate Immunity and Ocular
Inflammatory-Reparative Responses |
| |
Karsten Gronert, Associate Professor, Ophthalmology, University of
California, Berkeley |
| |
|
| |
Inflammation, a frequent and self-resolving response, is essential for
protection and integrity of tissues and is intimately linked to wound healing.
Healthy execution of inflammatory/reparative responses requires activation of
conserved resolution programs. Distinct classes of lipoxygenase (LOX)-derived
eicosanoids and their w-3 PUFA homologs
establish a tone of anti-inflammatory signals, are early response signals to
injury or infection and key regulators of resolution and healing. Our research
efforts are focused on elucidating function and regulation of these protective
lipid circuits in the eye. We have discovered intrinsic lipid circuits in the
cornea and retina that control inflammation, leukocyte function, wound healing
and angiogenesis. These protective lipid circuits are regulated by dietary
w-3 PUFA that amplify the generation of specific docosahexaenoic
acid-derived autacoids. Sex-specific differences in ocular
inflammatory/reparative responses and estrogen’s role in ocular diseases are not
well understood. Our ongoing work has uncovered that estrogen receptors
selectively regulate protective lipid circuits, which correlates with
estrogen-driven and sex-specific differences in wound healing and inflammation.
In addition, we recently discovered that eicosanoids are an early and obligatory
effector function of inflammasomes, which are critical intracellular sensor for
infection/stress and activators of essential cellular innate immune responses.
The lecture will present our current understanding of the formation, regulation
and mechanism of action of intrinsic lipid circuits and their potential role in
the pathogenesis of ocular inflammatory diseases. |

Early Detection of Amblyopia in the Primary Care Setting: A Cost Effective
Alternative to Vision Screening |
| |
Justin Shaka, Chief Executive Officer, REBIScan |
| |
|
| |
Amblyopia (“lazy eye”) and strabismus (misaligned
eyes) are medical eye conditions that combine as the leading causes of
preventable monocular vision loss in children, and are major contributors to
worldwide blindness. Amblyopia, which effects 5% of the population, is fully
treatable if caught early, yet millions of children suffer permanent vision loss
every year because of lack of detection.
The failure to detect amblyopia has become a public health catastrophe; however,
REBIScan has developed a hand-held device that has shown unprecedented accuracy
at detecting disease. Using patented technology based out of Johns Hopkins
University and Boston Children’s Hospital, clinical trials have shown the
Pediatric Vision Scanner (PVS) to be 98% accurate in children as young as the
age of 2. The PVS uses retinal birefringence scanning to analyze the nerve
fibers of the fovea, and, in under 3 seconds, provides an objective, binary
output.
By supplying this technology into primary care settings, we can catch amblyopia
when it starts, and reduce the inefficient spending that goes toward detecting
risk factors and false referrals to specialists. The combined cost of amblyopia
screening and strabismus surgery in the US is estimated to be $800 million
annually, while the cost to society from loss of function is estimated at well
over $20 billion. REBIScan’s solution to this problem will give access to a
newly developed technology to all children, thereby eliminating vision loss from
amblyopia, while introducing a cost-effective payment model.
Benefits of the talk:
1. Understanding the shortcomings of vision screening and how retinal
birefringence scanning solves those problems
2. Cost-effective methods to detecting disease over risk-factors
3. Realistic approach to eradicating vision loss as a result of amblyopia |

Sustained Delivery of Proteins and Antibodies – A drug delivery technology
that may provide opportunities
One of the many challenges to pharmaceutical industry is to develop
effective delivery systems for protein and antibody drugs. pSivida’s new
approach is using biocompatible and biodegradable structures of meso-porous
silicon to provide sustained delivery of therapeutics. The primary focus
with this technology is the delivery of large biologic molecules, including
proteins and antibodies. The pore diameter and surface area of meso-porous
silicon materials can be adjusted to enable the adsorption of specific
classes of proteins and antibodies. Adsorbed agents are then released on a
sustained basis over time. These materials are also being evaluated for the
delivery of smaller molecules.
• What are the challenges of deliver protein and antibody drugs
• pSivida’s drug delivery systems
• Meso-porous silicon properties and scientific background
• Sustained delivery will bring new life to protein and antibody drugs

Utility of a Mouse Model for Evaluation of Potential Therapies for
Age-related Macular Degeneration |
| |
Chi-Chao Chan, Chief, Immunopathology Section; Laboratory of Immunology; Head,
Histopathology Core, National Eye Institute, National Institutes of Health |
| |
|
| |
We use the Ccl2-/-/Cx3cr1-/- on rd8 background (DKO/rd8) mouse as a model
for age-related macular degeneration (AMD). These mice develop progressive
focal retinal degeneration characterized by photoreceptor and RPE atrophy,
elevated ocular A2E and immune dysfunction, plus retinal dystrophy from the
rd8 background. We examined the effect of feeding AREDS2 formulation to
DKO/rd8 mice: one group was fed the AREDS2 diet with lutein, zeaxanthin and
DHA/EPA, the other group was fed an isocaloric diet. After three months, 75%
of control DKO/rd8 mice had retinal lesion progression, compared to 19% of
AREDS2-treated mice. Ocular A2E levels were significantly lower and the mean
outer nuclear layer was also significantly thicker in AREDS2-treated mice
compared to the controls. Retinal expression of iNos, Tnf-?, Cox-2, and Vegf
were lower in AREDS2-treated eyes. The data suggest that oxidative
inflammatory damage was counteracted early enough to halt RPE damage and
photoreceptor loss, and thus support a beneficial effect of AREDS2
formulation for AMD. While the identification of rd8 and rd8-associated
retinal phenotype impacts the power of DKO/rd8 as an AMD model, the use of
the model as self-control by treating one eye as the control allows for
appropriate experimental interventional studies. In intervention studies on
DKO/rd8, treatment is shown to alleviate photoreceptor and RPE lesions that
can be attributed to Ccl2 and Cxcr3 null while showing little or no effect
on rd8 lesions. Therefore, DKO/rd8 may still serve as a suitable and
relevant model for compound screening on focal retinal degenerative diseases
including AMD. |

A Novel Approach to Treat Corneal Defects |
| |
 |
Barbara Wirostko
Chief Scientific Officer and Co-Founder
Jade Therapeutics
Clinical Adjunct Associate Professor, Ophthalmology
University of Utah
|
| |
|
| |
Jade Therapeutics develops
locally administered, sustained-release formulations of already-approved
drugs for use in poorly served ophthalmic indications. This approach could
enable improved therapeutic outcomes along with increased patient compliance
to therapy and decreased frequency of administration and office visits –
ultimately resulting in better visual function with enhanced quality of
life.
The Company’s initial focus is on a novel, bioresorbable topical ocular
product that elutes recombinant human growth hormone (rHGH) over a period of
approximately 1-2 weeks to help address persistent corneal epithelial
defects (PCED). PCED can result from injury to the eye (such as chemical or
blast trauma), disease of the eye (including ocular infections, severe dry
eye, neurotrophic keratitis, diabetic neuropathies, and neurologic palsies),
and various ocular surgeries. Practitioners report that today’s therapeutic
options are quite limited as there are currently no approved drugs designed
to help heal the ocular surface in general or to resolve corneal defects in
particular.
Commercially available, systemically administered rHGH has been used safely
for decades by thousands of patients for various non-ophthalmic indications,
where it has been shown broadly to activate epithelial and other cell types
in order to repair and build tissue. Jade’s own studies have demonstrated
promising results in accelerating corneal healing in various rabbit models.
Aims of the presentation:
• Better characterize PCED as a disease and the associated unmet need
• Share the MOA/rationale for rHGH in treating PCEDs
• Discuss the data that exist for non-ocular wound healing
• Share the preclinical data to date for Jade’s product |

Gene Therapy for the Treatment of Neovascular AMD |
| |
Abraham Scaria, Senior Scientific Director,
Genzyme |
| |
|
| |
VEGF plays a critical role in neovascular
age-related macular degeneration and proliferative diabetic retinopathy. VEGF
antagonists are useful for treating such disorders; however current treatments
require monthly intravitreal injections. We have designed a soluble anti-VEGF
molecule (sFLT01) and delivered it by intravitreal injection of an
adeno-associated viral (AAV) vector since AAV vectors are capable of long-term
gene expression. AAV2-sFLT01 inhibited retinal neovascularization in the murine
oxygen-induced retinopathy model and in the laser-induced choroidal
neovascularization (laser-CNV) model in mice. In the eyes of rodents and
cynomolgus monkeys, AAV2-sFLT01 gives expression levels persistent for at least
one year. We also performed laser-CNV experiments 5 months after vector
administration in non-human primates and showed that sFLT01 is effective at
inhibiting neovascularization in this model. Results of our 12-month safety
study of AAV2-sFLT01 administered intravitreally in cynomolgus monkeys will be
discussed. In summary, we have demonstrated long-term efficacy with minimal side
effects following intravitreal delivery of AAV-sFLT01 in rodents and non-human
primate models. These results suggest an alternate method for the long-term
treatment for diseases of ocular neovascularization, without the need for
repeated intraocular injections. A Phase I clinical trial is under way at four
clinical sites in the USA. |

PRINT Technology for Ocular Drug Delivery |
| |
Kenneth J. Mandell, Vice President, Early
Development, Liquidia Technologies, Inc. |
| |
|
| |
As many as 285 million people suffer from
disease-related visual impairments and blindness wordlwide. Unfortunately, the
safety and effectiveness of many medical therapies for ocular disorders are
limited due to poor ocular drug uptake, non-specificity to target tissues,
systemic side effects, and poor adherence to therapy. To address these critical
unmet needs, Liquidia is using its proprietary PRINT technology platform to
rationally design and manufacture micro- and nano-particle systems for the
treatment of ocular diseases. The PRINT particles, which can consist of both
small molecule and biologic therapeutics, are designed and manufactured with the
goal of improving the delivery, safety and efficacy of medicines used to treat
ocular disease. The technology can be used to precisely engineer particles of
virtually any size, shape and chemistry and finely tune them to perform as
highly targeted therapeutics with enhanced effectiveness and safety.
Additionally, the ability to engineer therapeutic particles with tunable release
kinetics could significantly reduce dosing requirements and increase patient
compliance. The PRINT technology platform can be applied to topical therapies to
achieve a highly homogenous distribution on the ocular surface with the
potential for increased retention and tolerability. Such advancements could
allow for the delivery of ocular therapies with improved therapeutic index using
fewer doses and result in improved patient compliance and therapeutic outcomes.

Suprachoroidal Drug Delivery: Clinical and Pre-Clinical Experience |
| |
Samirkumar Patel, Director, Research and New
Product Development, Clearside Biomedical |
| |
|
| |
Treating diseases that affect the posterior
segment of the eye is primarily done by direct injection of drugs into the
vitreous. Currently doctors have very few viable options to deliver a drug
directly to the choroid and retina where the pathology of many posterior segment
diseases occurs. Direct injection into the suprachoroidal space with a
microneedle can accomplish this and be done in a minimally invasive manner. This
talk will focus on how injecting drugs into the suprachoroidal space using
Clearside’s proprietary microneedle, has demonstrated efficacy in posterior
inflammation (uveitis) in animal models and early human clinical safety
experience.
Benefits/topic covered:
- An understanding of the microinjection technology
- An understanding of the suprachoroidal space anatomy and benefits of drug
administration to this space
- Safety and efficacy data on suprachoroidal delivery in animal models
- Early clinical safety experience with Clearside’s suprachoroidal
microinjection technology in human subjects |

Polyesteramides: Materials, Formulation and Processes for Ocular Drug Delivery |
| |
John Zupancich, Staff Scientist, DSM
Biomedical |
| |
|
| |
The incorporation of amino acid-based units into resorbable, biodegradable
polymers introduces not only metabolisable building blocks within the polymer,
but also one or more functional groups along the polymer chain. This allows
modification of the polymer to tailor its physicochemical properties,
bio-erosion and performance as drug eluting matrices. DSM is developing a
portfolio of polyesteramide polymers (“PEAs”) based on
a-amino acids, aliphatic dicarboxylic acids and aliphatic
a-w diols. A
main advantage of PEAs is that by design, they predominantly degrade via an
enzymatic mechanism and consequently due to exclusive surface erosion, drug
release follows nearly zero-order kinetics.
Recently, significant advances have been made in optimizing the delivery of
drugs to target tissues within the eye. Although topical administration remains
the most common method, application of injectable, degradable ocular delivery
devices provide better control over dosage, reduces amounts of formulated drug
required and offers the opportunity to delivery drug more efficiently to the
posterior segment of the eye.
In this presentation we will present DSM’s portfolio of PEAs and address various
topics on ocular biocompatibility, degradation, processing and utility as a 6+
month sustained release delivery vehicle using latanoprost and dexamethasone as
examples. |

Drug-Eluting Contact Lenses |
| |
|
| |
Joseph B. Ciolino, Assistant Professor, Ophthalmology, Mass. Eye & Ear
Infirmary, Harvard Medical School |
| |
|
| |
Purpose: To the report the in vitro and in vivo results in the
development of a latanoprost-eluting contact lens designed for the treatment of
glaucoma.
Methods: Drug-eluting therapeutic contact lenses (TCL) were created by
encapsulating drug-polymer films in methafilcon A by ultraviolet light
polymerization. TCLs were placed in phosphate buffered solution at 37°C with
continuous rotation. The release media was sampled and changed daily. Drug
concentrations were measured with an enzyme-linked immunosorbent assay (ELISA).
TCLs were inserted on the left eye of New Zealand white rabbits for 4 weeks. The
eyes were examined under an operating microscope and the anterior chamber (AC)
fluid was collected during 28 days of continuous wear. For comparison,
latanoprost 0.005% solution (drops) was topically applied and the AC fluid was
sampled after drop administration (1, 3, 6, 12, and 24 hrs). Each sample was
collected on a different day and the AC drug concentration was measured by
ELISA. The 24-hr area under the curve (AUC) for latanoprost drops was calculated
and compared to the AC concentration measured during 28 days of TCL wear.
Results: In vitro, TCLs demonstrated an initial burst and then eluted a
sustained and therapeutic daily amount of latanoprost for 4 weeks. In vivo, the
TCLs demonstrated no signs of toxicity. Through 28 days of continuous wear, the
TCLs delivered a therapeutic level of latanoprost to the anterior chamber
without any signs of toxicity.
Conclusions: This contact lens design can potentially be used as a treatment for
glaucoma and as a platform for ocular drug delivery with widespread
applications.
“Benefits”
-Highlight potential future therapeutics
-Discuss the potential of contact lens drug delivery
-Discuss advantages and disadvantages of contact lenses as a means of drug

Applying Primate Ophthalmic Models to Realize Clinical Objectives |
| |
Matthew Lawrence, CSO & CEO, RxGen |
| |
|
| |
Navigating the path from basic science discovery
or clinical observation to new approved therapeutic strategy is demanding,
requiring careful consideration of preclinical and clinical strategy, resources,
time, talent and the quality of data and analysis applied. Before setting off on
that path, and along that path, many decisions are required, not least of which
is the validity of the preclinical models employed and the manner in which they
are applied, and their interpretation with respect to the specific clinical
indication being pursued. In ophthalmology, non-human primate models represent
an important, and in some instances, essential test system in which to evaluate
pharmacology, efficacy and/or safety, both to de-risk a program in the early
stages of development, and at a later stage, given the significant investment of
time and resources required for clinical trials, to provide confidence in safely
and effectively pursuing the proposed clinical strategy. The rationale and
practical considerations for why, when, how and where to extend preclinical
modeling into non-human primates is not always clear without balanced attention
to comparative medicine, regulatory, technical, and cost considerations. This
can be achieved by early engagement with groups routinely implementing and
refining validated, clinically predictive models. Where such models do not
exist, goals can be met by pursuing collaborative and consortia approaches to
expand the model portfolio available for immediate development needs, and
ultimately to the broader ophthalmic research community and the clinical
challenges we collectively address. The objectives of effective and efficient
translational development will be discussed in this context. |

Dark Adaptation: A Functional Clinical Trial Endpoint for Age-related Macular
Degeneration |
| |
Gregory Jackson, Associate Professor, Ophthalmology, Penn State University |
| |
|
| |
Age-related macular degeneration is a progressive
chronic retinal disease. AMD causes the deterioration of the Bruch’s
membrane/retinal pigment epithelium cell complex which compromises photoreceptor
function and health. Disruption of retinal pigment epithelium function alters
the retinoid cycle which primarily governs the speed of dark adaptation. Slowed
dark adaptation is a prominent deficit of visual function in patients with early
AMD. Cone recovery is slower. The rod-cone break and rod intercept are delayed,
and the slope of the second component of rod-mediated dark adaptation is
shallower. Studies of dark adaptation in AMD patients report increasing
impairment of DA with increasing disease severity. This relationship suggests
that there is a progressive loss of dark adaptation with disease progression. A
significant change in DA parameters within one year might be a useful marker of
disease progression which could be modified by therapeutic intervention. To
address this possibility, we have conducted a 12-month natural history study of
DA in patients with mild to intermediate AMD. We found that nearly 20% of
patients with AMD exhibited a significant change in dark adaptation while
maintaining stable acuity and AREDS severity grade. This study suggests that
dark adaptation may be a suitable functional endpoint for early clinical studies
evaluating novel treatments for early to intermediate AMD.
Benefits
1. A framework for the validation of novel functional clinical trial endpoints
will be presented
2. Data will be presented supporting dark adaptation as a clinical trial
endpoint for age-related macular degeneration
3. The 12-month natural history of dark adaptation in early to intermediate AMD

New Advances in the Development of Rho Kinase Inhibitors for the Treatment of
Glaucoma |
| |
Casey Kopczynski, Chief Scientific Officer,
Aerie Pharmaceuticals |
| |
|
| |
The objective of Aerie’s development program is to bring new, more effective
treatment options to patients with glaucoma or ocular hypertension. Aerie's
glaucoma pipeline includes novel inhibitors of Rho kinase (ROCK) that lower
intraocular pressure (IOP) through a new mechanism of action, improving the
outflow of aqueous humor through the trabecular meshwork (TM).
AR-12286 is a first-in-class ROCK inhibitor that has demonstrated an excellent
safety and efficacy profile in Phase 2 clinical studies as a once-daily eye
drop. Aerie has developed the first fixed-dose combination (FDC) of a ROCK
inhibitor plus a prostaglandin agonist, PG286 (AR-12286 plus travoprost), and
evaluated the efficacy and safety of this FDC vs. travoprost monotherapy in a
7-day Phase 2a clinical study. PG286 was well tolerated and reduced 8 AM IOP by
12.2 mmHg (46%) compared to 9.1 mmHg (34%) for travoprost. PG286 has the
potential to become the most effective once-daily combination product for
treating glaucoma.
AR-13324 is the first of a new class of glaucoma drugs that lowers IOP through a
unique dual mechanism of action, increasing TM outflow through ROCK inhibition
while also decreasing the production of aqueous humor. A first-in-human Phase 2a
study evaluating AR-13324 0.01%, 0.02% and 0.04% dosed once-daily in the morning
has been completed. All dose levels produced large reductions in IOP. AR-13324
0.02% defined the top of the dose response curve and was well tolerated. The
results suggest peak efficacy is achieved >8 hours after dosing, and that
maximal efficacy will be achieved with evening dosing.

Challenging conventional wisdom can be an uphill
battle when innovating, especially in clinical development of a drug. The
payoffs can be huge. A leader must demonstrate passion, tenacity, creativity,
and perhaps a stubborn streak. Learn about MacuCLEAR’s aggressive clinical
program for The Chiou Syndrome, its novel drug MC-1101 for treating dry AMD, and
how it resulted in a pivotal trial design using novel endpoints. Understand how
they are championing uncharted territories with the FDA and in a cost effective
way.
The attendee should come away with:
• Guidelines for working with FDA
• Getting functionally relevant novel endpoints considered for novel targets
• Managing risk in clinical development
• A “passing attack” approach to technology development that leads to truth
seeking and cost efficiency. |
