Development
Program for the Treatment of DME
We are currently conducting two Phase 3 pivotal clinical trials
(individually referred to as Trial A and Trial B, and
collectively as our FAME Study) for Iluvien involving
956 patients in sites across the United States, Canada,
Europe and India to assess the efficacy and safety of Iluvien in
the treatment of DME. Combined enrollment was completed in
October 2007, and the month 24 clinical readout from our FAME
Study was received in December 2009. We believe that the month
24 data supports approval of the low dose of Iluvien for the
treatment of DME. Therefore, we plan to proceed with the
preparation of a registration dossier and to submit an NDA in
the United States for the low dose of Iluvien to the FDA in
the second quarter of 2010 with the month 24 clinical data,
followed by registration filings in certain European countries
and Canada.
Consistent with the FDA requirement for registration and
approval of drugs being developed for diabetic retinopathy,
including DME, the primary efficacy endpoint for our FAME Study
is the difference in the percentage of patients whose best
corrected visual acuity (BCVA) improved from baseline by 15 or
more letters on the Early Treatment Diabetic Retinopathy Study
(ETDRS) eye chart between the treatment and control groups at
month 24. The ETDRS eye chart is the standard used in clinical
trials for measuring sharpness of sight as established by the
National Eye Institutes Early Treatment Diabetic
Retinopathy Study. In addition, the FDA requires a numerical
comparison of the percentage of patients with BCVA improvement
of 15 or more letters between the month 24 and month 18 data to
determine if the month 24 results are equal to or greater than
the month 18 results. Patients enrolled in our FAME Study will
be followed for 36 months. Although we will submit the
additional 12 months of clinical data to applicable regulatory
authorities, the approval of Iluvien by regulatory authorities,
including the FDA, will be based on the month 24 clinical data
from our FAME Study.
We believe that Iluvien meets the requirements for Priority
Review in the United States and we intend to make a formal
request for this review classification when we file our NDA with
the FDA. Upon receipt, the FDA will notify us within
60 days of Iluviens final review classification. In
the European Union, we will be utilizing the
1
decentralized registration procedure. The Iluvien insertion
system will not require a separate device application, but it
must meet the safety and regulatory requirements of the
applicable regulatory authorities when evaluated as part of the
drug product marketing application.
FAME
Study
We initiated our FAME Study in September 2005. Trial A and Trial
B have identical protocols and completed enrollment in October
2007 with a total of 956 patients across 101 academic and
private practice centers. Trial A drew patients from sites
located in the northern regions of the United States, Europe and
India and all sites in Canada, while sites in the southern
regions of the United States, India and Europe comprise Trial B.
Our FAME Study was designed to assess the safety and efficacy of
Iluvien in patients with DME involving the center of the macula,
and who had at least one prior macular laser treatment
12 weeks or more before study entry. The inclusion criteria
for our FAME Study were designed to select DME patients with
BCVA between 20/50 (68 letters on the ETDRS eye chart) and
20/400 (19 letters on the ETDRS eye chart) in the study eye
and no worse than 20/400 in the non-study eye. Patients who had
received steroid drug treatments for DME within three months of
screening or anti-VEGF injections within two months of
screening, and patients with glaucoma, ocular hypertension, IOP
greater than 21mmHg or concurrent therapy with IOP-lowering
agents in the study eye at screening were not eligible to
participate in this trial.
The following table describes the baseline characteristics of
the patients randomized into our FAME Study.

Patient characteristics, such as age, gender and baseline BCVA,
were balanced across the treatment and control groups. As part
of randomization, the patients were divided into two separate
groups, those with a baseline BCVA score greater than or equal
to 49 letters on the ETDRS eye chart and those with a baseline
BCVA score of less than 49 letters on the ETDRS eye chart.
We randomly assigned patients participating in our FAME Study to
one of three groups at a ratio of 2:2:1. The first two of these
groups were assigned to an active drug formulation and the third
group serves as the control group, undergoing a sham insertion
procedure designed to mimic an intravitreal insertion. The
treatment groups consist of one group receiving a low dose of
Iluvien and another group receiving a high dose of Iluvien. To
reduce potential bias, these trials use a randomized,
double-masked study design so that neither the patient nor the
investigational staff involved with assessing the patient knows
to which group the patient belongs. In order to simulate an
insertion and help to maintain proper patient masking, the sham
insertion procedure includes all steps involved in the insertion
procedure, except that a blunt inserter without a needle is used
to apply pressure to the anesthetized eye.
As part of our FAME Study, investigators were able to re-treat
each patient with Iluvien following their month 12 follow up
visit. Through month 24, 24.5% of patients had been treated
with more than one Iluvien insert and 2.5% of patients had been
treated with three or more Iluvien inserts.
Primary Efficacy Endpoint. The primary
efficacy endpoint for our FAME Study is the difference in the
percentage of patients with improved BCVA from baseline of 15 or
more letters on the ETDRS eye chart at month 24 between the
treatment and control groups. In December 2009, we received the
month 24 clinical readout for our FAME Study and have analyzed
the full data set consistent with the recommendations regarding
the appropriate
2
population for primary analysis as described in the
FDA-adopted
International Conference on Harmonization of Technical
Requirements for Registration of Pharmaceuticals for Human Use
(ICH) Guidance E9, Statistical Principles for Clinical
Trials. ICH is a joint initiative involving regulatory
authorities and pharmaceutical industry representatives from
Europe, Japan and the United States who discuss scientific and
technical aspects of product registration.
The full data set includes all 956 patients randomized into
our FAME Study, with data imputation employed, using last
observation carried forward (LOCF), for data missing
because of patients who discontinued the trial or are
unavailable for
follow-up
(the Full Analysis Set). As part of our analyses, we determined
statistical significance based on the Hochberg-Bonferroni
procedure (H-B procedure), which is a procedure employed to
control for multiple comparisons. We also made a target
p-value
adjustment of 0.0001 to account for each of the nine instances
our independent data safety monitoring board reviewed unmasked
interim clinical data. These adjustments resulted in a required
p-value of
0.0491 or lower for each of Trial A and Trial B to
demonstrate statistical significance for both the low dose and
high dose of Iluvien. Based upon the H-B procedure, if either
dose of Iluvien in a trial did not meet statistical
significance, the alternate dose was required to achieve a
p-value of 0.02455 or lower in that trial to demonstrate
statistical significance.
In the Full Analysis Set, the primary efficacy endpoint was met
with statistical significance for both the low dose and the high
dose of Iluvien in Trial A and Trial B, as well as on
a combined basis. The table below summarizes the primary
efficacy variable results.

Additionally, as required by the FDA, a numerical comparison of
the responder rates at month 18 and month 24 in the Full
Analysis Set demonstrated that the responder rates for both the
low dose and high dose of Iluvien at month 24 were numerically
greater than the month 18 responder rates in both Trial A
and Trial B.
Based on these results, we plan to submit an NDA in the United
States for the low dose of Iluvien in the second quarter of
2010, followed by registration filings in various European
countries and Canada. We intend to request Priority Review of
our NDA from the FDA. If Priority Review is granted, we can
expect a response to our NDA from the FDA in the fourth quarter
of 2010.
Our FAME Study protocol provides for analyses of additional data
sets. The all-randomized and treated data set includes
953 patients randomized into our FAME Study and treated,
with data imputation employed, using the LOCF method, for data
missing because of patients who discontinued the trial or are
unavailable for
follow-up
(the ART Data Set). Three patients who were randomized, but not
treated, are included in the Full Data Set and excluded from the
ART Data Set. In the ART Data Set, the primary efficacy endpoint
was met with statistical significance for both doses of Iluvien
in both Trial A and Trial B. The percentage of
patients in the ART Data Set achieving improved BCVA of 15 or
more letters at month 24 for Trial A is 14.7% for the
control group, 26.8% for the low dose
3
(p-value
0.029) and 26.2% for the high dose
(p-value
0.032). The percentage of patients in the ART Data Set achieving
improved BCVA of 15 or more letters at month 24 for
Trial B is 17.8% for the control group, 30.8% for the low
dose
(p-value
0.028) and 31.3% for the high dose
(p-value
0.026).
The modified ART Data Set includes all 953 patients
included in our ART Data Set and excludes data collected
subsequent to the use of treatments prohibited by the protocol,
such as Avastin, Lucentis, triamcinolone acetonide or vitrectomy
(the Modified ART Data Set). In instances when a treatment
prohibited by our FAME study protocol was used, the last
observation prior to the protocol violation was imputed forward
to month 24 using the LOCF method. The percentage of patients in
the Modified ART Data Set achieving improved BCVA of 15 or more
letters for Trial A is 12.6% for the control group, 22.6%
for the low dose
(p-value
0.057) and 24.1% for the high dose
(p-value
0.026). Neither dose of Iluvien for Trial A was
statistically significant based on the
H-B procedure.
The percentage of patients in the Modified ART Data Set
achieving improved BCVA of 15 or more letters at month 24
for Trial B is 13.3% for the control group, 29.7% for the
low dose
(p-value
0.004) and 29.3% for the high dose
(p-value
0.005). Both doses of Iluvien for Trial B were
statistically significant.
Our FAME Study protocol provides that the primary assessment of
efficacy is based on the Modified ART Data Set and that other
data sets are considered secondary. The protocol did not specify
the Full Analysis Set as a data set for analyzing the study;
however, consistent with the recommendations regarding the
appropriate population for primary analysis as described in the
FDA-adopted ICH Guidance E9, we believe that the FDA will
consider the Full Analysis Set to be the most relevant data set
for determining the safety and efficacy of Iluvien in
Trials A and B.
Additional Clinical Observations. In addition
to the primary efficacy variable, we also observed a number of
other clinically relevant results in the month 24 clinical data
from our FAME Study. These observations included, among others,
the following:
|
|
|
|
|
patients with improved BCVA of 15 or more letters at each follow
up visit;
|
|
|
|
patients with improved BCVA of 15 or more letters at any time
point;
|
|
|
|
other levels of BCVA improvement at month 24;
|
|
|
|
BCVA improvement of 15 or more letters relative to baseline
BCVA; and
|
|
|
|
decrease in excess foveal thickness.
|
The analyses of these Full Analysis Set observations set forth
below are presented for Trial A and Trial B on a
combined basis for patients who received the low dose of Iluvien
in comparison to the control group.
Patients With Improved BCVA of 15 Letters or More at Each
Follow Up Visit. Our analysis of the results of
the FAME Study through month 24 indicates that the low dose of
Iluvien provides an improvement in BCVA as early as three weeks
after insertion. The low dose of Iluvien was statistically
significantly better than the control group in our FAME Study by
week 3 of patient follow up, and maintained a statistically
significant advantage over the control through month 24. The
chart below demonstrates the treatment effect of the low dose of
Iluvien versus the control group, as measured by an improvement
in BCVA of 15 letters or more, at each scheduled follow up visit
during the FAME Study.
4
Patients With Improved BCVA of 15 or More Letters at Any Time
Point. Our analysis of the results of the FAME
Study through month 24 indicates that a significantly greater
percentage of patients receiving the low dose of Iluvien versus
the control group had an improvement in BCVA of 15 letters or
more when assessed at any follow up visit. During the first
24 months of the FAME Study, 177 out of 376 patients
randomized to receive the low dose of Iluvien, or 47.1%,
demonstrated improved BCVA of 15 letters or more at any time
point compared to 51 out of 185 patients, or 27.6%,
randomized to the control group.
Other Levels of BCVA Improvement at Month
24. While the FDAs requirement for the
registration and approval of drugs being developed for DME is
that the primary efficacy variable be based on an improvement in
BCVA of 15 letters or more, lesser degrees of improvement in
BCVA are considered clinically significant. The table below
demonstrates the low dose of Iluviens statistically
significant improvements in BCVA versus the control group at
month 24 of our FAME Study.

BCVA Improvement of 15 or More Letters Relative to Baseline
BCVA. Our analysis of the results of the FAME
Study at month 24 indicates that Iluvien has a statistically
significant advantage over the control group irrespective of the
severity of a patients baseline BCVA. The table below
demonstrates the statistically significant treatment effect of
Iluvien versus the control group in patients with baseline BCVA
of more than 49 letters on the EDTRS eye chart, and patients
with BCVA of 49 letters or less on the EDTRS eye chart at
baseline.

Decrease In Excess Foveal Thickness. In
addition to the functional measures of BCVA, we assessed the
effect of Iluvien using an anatomic measure, namely the decrease
in excess foveal thickness as determined by optical coherence
tomography. Excess foveal thickness is a measurement of the
swelling of the macula at its center point (known as the fovea).
We consider any measurement above 180 microns to represent
excess foveal thickness. Based on a review of the month 24
clinical readout as summarized in the chart below, patients
receiving the low dose
5
of Iluvien demonstrated a statistically significant difference
versus the control group in decreasing excess foveal thickness
by week 1 of patient follow up of our FAME Study, and
maintain a statistically significant advantage through month 24.
At month 24, patients receiving the low dose of Iluvien
demonstrated a mean decrease in excess foveal thickness of 156.1
microns versus 100.5 microns for the control group.
Safety. Iluvien was well tolerated through
month 24 of our FAME Study in both the low and high dose patient
populations. Our preliminary assessment of adverse event data
indicates that there is no apparent risk of systemic adverse
events to patients as a result of the use of Iluvien. The use of
corticosteroids in the eye is primarily associated with two
undesirable side effects: increased IOP, which may increase the
risk of glaucoma and require additional procedures to manage,
and cataract formation. Excluding IOP related side effects and
cataracts, we observed no significant eye related adverse events
when comparing both the low dose and high dose patient
populations to control. Thus, based on the month 24 clinical
readout from our FAME Study, we believe that the adverse events
associated with the use of Iluvien are within the acceptable
limits of a drug for the treatment of DME.
The table below summarizes the IOP related adverse events
occurring in all patients randomized and treated in our
FAME Study.

An IOP of 30 mmHg is a clinically significant level that we use

According to the CDC, diabetic individuals aged 50 or older are
1.5 times more likely to develop cataracts than non-diabetic
individuals. A review of the baseline characteristics of our
patient population reflects this increased risk of cataracts for
diabetic patients, with 34.3% of the patients randomized into
our FAME Study having previously undergone a cataract surgery in
the study eye. The month 24 clinical readout from our FAME Study
6
demonstrated that of the patients who had a natural lens (no
prior cataract surgery) at baseline, 43.6% of the control group,
80.0% of the low dose and 87.5% of the high dose had cataract
formation reported as an adverse event. Additionally, of the
patients who had a natural lens at baseline, 23.1% of the
control group, 74.9% of the low dose and 84.5% of the high dose
underwent cataract surgery.
PK
Study
We initiated an open-label Phase 2 human pharmacokinetic
clinical study (PK Study) in August 2007 to assess the systemic
exposure of FA by measuring plasma levels of FA. Analysis of
plasma levels through month 18 in September 2009 demonstrated no
systemic exposure of FA (plasma levels were below the limit of
detection of 100 picograms per milliliter). Based on these
results, we intend to file a carcinogenicity waiver with the
applicable regulatory authorities, including with the FDA in
connection with our NDA submission.
A total of 37 patients were enrolled in the PK Study,
17 patients on the high dose of Iluvien and
20 patients on the low dose of Iluvien. The last patient
was enrolled in the study at the end of February 2008. Data from
the PK Study are being evaluated on an ongoing basis with
interim evaluations at months 3, 6, 12, 18, 24, 30 and 36.
Risks
Related to Our Business and Industry
We are
heavily dependent on the success of our lead product candidate,
Iluvien, which is still under development. If we are unable to
commercialize Iluvien, or experience significant delays in doing
so, our business will be materially harmed.
We have invested a significant portion of our time and financial
resources in the development of Iluvien, our only product
candidate in clinical development. We anticipate that in the
near term our ability to generate revenues will depend solely on
the successful development and commercialization of Iluvien.
Based on our analysis of the month 24 clinical readout from our
Phase 3 pivotal clinical trials for the use of Iluvien in the
treatment of diabetic macular edema, or DME (collectively, our
FAME Study), we plan to file a New Drug Application (NDA) for
the low dose of Iluvien in the United States in the second
quarter of 2010, followed by registration filings in certain
European countries and Canada. However, we may not complete our
registration filings in our anticipated time frame. Even after
we complete our NDA filing, the U.S. Food and Drug
Administration (FDA) may not accept our submission, may request
additional information from us, including data from additional
clinical trials, and, ultimately, may not grant marketing
approval for Iluvien. In addition, although we believe the month
24 clinical readout from our FAME Study demonstrates that
Iluvien is effective in the treatment of DME, clinical data
often is susceptible to varying interpretations and many
companies that have believed that their products performed
satisfactorily in clinical trials have nonetheless failed to
obtain FDA approval for their products.
If we are not successful in commercializing Iluvien, or are
significantly delayed in doing so, our business will be
materially harmed and we may need to curtail or cease
operations. Our ability to successfully commercialize Iluvien
will depend, among other things, on our ability to:
|
|
|
|
|
successfully complete our clinical trials;
|
|
|
|
produce, through a validated process, batches of Iluvien in
quantities sufficiently large to permit successful
commercialization;
|
|
|
|
receive marketing approvals from the FDA and similar foreign
regulatory authorities;
|
|
|
|
establish commercial manufacturing arrangements with third-party
manufacturers;
|
|
|
|
launch commercial sales of Iluvien; and
|
|
|
|
secure acceptance of Iluvien in the medical community and with
third-party payors.
|
We face
heavy government regulation, and approval of Iluvien and our
other product candidates from the FDA and from similar entities
in other countries is uncertain.
The research, testing, manufacturing and marketing of drug
products are subject to extensive regulation by U.S. federal,
state and local government authorities, including the FDA, and
similar entities in other countries. To
7
obtain regulatory approval of a product, we must demonstrate to
the satisfaction of the regulatory agencies that, among other
things, the product is safe and effective for its intended use.
In addition, we must show that the manufacturing facilities used
to produce the products are in compliance with current Good
Manufacturing Practice (cGMP) regulations.
The process of obtaining regulatory approvals and clearances
will require us to expend substantial time and capital. Despite
the time and expense incurred, regulatory approval is never
guaranteed. The number of preclinical and clinical tests that
will be required for regulatory approval varies depending on the
drug candidate, the disease or condition for which the drug
candidate is in development and the regulations applicable to
that particular drug candidate. Regulatory agencies, including
those in the United States, Canada, the European Union and other
countries where drugs are regulated, can delay, limit or deny
approval of a drug candidate for many reasons, including that:
|
|
|
|
|
a drug candidate may not be safe or effective;
|
|
|
|
regulatory agencies may interpret data from preclinical and
clinical testing in different ways from those which we do;
|
|
|
|
they may not approve of our manufacturing process;
|
|
|
|
they may conclude that the drug candidate does not meet quality
standards for stability, quality, purity and potency; and
|
|
|
|
they may change their approval policies or adopt new regulations.
|
The FDA may make requests or suggestions regarding conduct of
our clinical trials, resulting in an increased risk of
difficulties or delays in obtaining regulatory approval in the
United States. For example, the FDA may object to the use of a
sham injection in our control arm or may not approve of certain
of our methods for analyzing our trial data, including how we
evaluate the risk/benefit relationship. Further, we intend to
market Iluvien, and may market other product candidates, outside
the United States and specifically in the European Union and
Canada. Regulatory agencies within these countries will require
that we obtain separate regulatory approvals and comply with
numerous and varying regulatory requirements. The approval
procedures within these countries can involve additional
testing, and the time required to obtain approval may differ
from that required to obtain FDA approval. Additionally, the
foreign regulatory approval process may include all of the risks
associated with obtaining FDA approval. For all of these
reasons, we may not obtain foreign regulatory approvals on a
timely basis, if at all. Approval by the FDA does not ensure
approval by regulatory authorities in other countries or
jurisdictions, and approval by one foreign regulatory authority
does not ensure approval by regulatory authorities in other
foreign countries or jurisdictions or by the FDA.
We plan to submit an NDA in the United States for the low dose
of Iluvien in the second quarter of 2010 with 24 months of
clinical data from our FAME study, followed by registration
filings in certain European countries and Canada. Consistent
with recommendations regarding the appropriate population for
primary analysis as described in the FDA-adopted
International Conference on Harmonization of Technical
Requirements for Registration of Pharmaceuticals for Human Use
(ICH) Guidance E9, Statistical Principals for
Clinical Trials, we believe that the FDA will consider the
most relevant population for determining safety and efficacy to
be the full data set of all 956 patients randomized into
our FAME Study, with data imputation employed using last
observation carried forward, for data missing because of
patients who discontinued the trial or are unavailable for
follow-up
(the Full Analysis Set). The primary efficacy endpoint was met
with statistical significance for both the low dose and the high
dose of Iluvien in both trials using the Full Analysis Set and
we intend to submit an analysis based on this data set for the
low dose to the FDA. However, our FAME Study protocol did not
include the Full Analysis Set and provides that the primary
assessment of efficacy will be based on another data set that
excludes from the Full Analysis Set three patients who were
enrolled but never treated as well as data collected for
patients subsequent to their use of treatments prohibited by our
FAME Study protocol (the Modified ART Data Set). Statistical
significance was not achieved for either the low dose or the
high dose in one trial using the Modified ART Data Set. There is
no assurance that that the FDA will utilize the Full Analysis
Set and not the Modified ART Data Set or another data set in
determining whether Iluvien is safe and effective, which could
result in the FDA not granting marketing approval for Iluvien.
8
In addition, although we expect to obtain a waiver from
regulatory agencies for the requirement to perform a
carcinogenicity study in animals, this waiver is dependent upon
our demonstration of negligible systemic absorption exposure of
the active fluocinolone acetonide (FA) in our open-label Phase 2
human pharmacokinetic clinical study (PK Study) which we may not
be able to demonstrate beyond month 18. Carcinogenicity studies
identify a tumorigenic potential in animals and are used to
assess the relevant risk in humans.
Any delay or failure by us to obtain regulatory approvals for
our product candidates could diminish competitive advantages
that we may attain and would adversely affect the marketing of
our products. We have not yet received regulatory approval to
market any of our product candidates in any jurisdiction.
Iluvien
utilizes FA, a corticosteroid that has demonstrated undesirable
side effects in the eye; therefore, the success of Iluvien will
be dependent upon the achievement of an appropriate relationship
between the benefits of its efficacy and the risks of its
side-effect profile.
The use of corticosteroids in the eye has been associated with
undesirable side effects, including increased incidence of
intraocular pressure (IOP), which may increase the risk of
glaucoma, and cataract formation. We have received only the
month 24 clinical readout from our FAME Study and the extent of
Iluviens long-term side effect profile is not yet known.
Upon review of our NDA for the low dose of Iluvien in the
treatment of DME, the FDA may conclude that our FAME Study did
not demonstrate that Iluvien has sufficient levels of efficacy
to outweigh the risks associated with its side-effect profile.
Conversely, the FDA may conclude that Iluviens side-effect
profile does not demonstrate an acceptable risk/benefit
relationship in line with Iluviens demonstrated efficacy.
In the event of such conclusions, we may not receive regulatory
approval from the FDA or from similar regulatory agencies in
other countries.
Even if
we do receive regulatory approval for Iluvien, the FDA or other
regulatory agencies may impose limitations on the indicated uses
for which Iluvien may be marketed, subsequently withdraw
approval or take other actions against us or Iluvien that would
be adverse to our business.
Regulatory agencies generally approve products for particular
indications. If any such regulatory agency approves Iluvien for
a limited indication, the size of our potential market for
Iluvien will be reduced. For example, our potential market for
Iluvien would be reduced if the FDA limited the indications of
use to patients diagnosed with only clinically significant DME
as opposed to DME or restricted the use to patients exhibiting
IOP below a certain level at the time of treatment. Product
approvals, once granted, may be withdrawn if problems occur
after initial marketing. If and when Iluvien does receive
regulatory approval or clearance, the marketing, distribution
and manufacture of Iluvien will be subject to regulation in the
United States by the FDA and by similar entities in other
countries. We will need to comply with facility registration and
product listing requirements of the FDA and similar entities in
other countries and adhere to the FDAs Quality System
Regulations. Noncompliance with applicable FDA and similar
entities requirements can result in warning letters,
fines, injunctions, civil penalties, recall or seizure of
Iluvien, total or partial suspension of production, refusal of
regulatory agencies to grant approvals, withdrawal of approvals
by regulatory agencies or criminal prosecution. We would also
need to maintain compliance with federal, state and foreign laws
regarding sales incentives, referrals and other programs.
Iluvien
may not be granted Priority Review by the FDA and, even if
Iluvien receives Priority Review, Iluvien may not receive
approval within the six-month review/approval cycle.
We believe that Iluvien may be eligible for Priority Review
under FDA procedures. We will request Priority Review for
Iluvien at the time we submit our NDA. Although the FDA has
granted Priority Review to other products that treat retinal
disease (including Visudyne, Retisert, Macugen, Lucentis and
Ozurdex), Iluvien may not receive similar consideration.
However, even in the event that Iluvien is designated for
Priority Review, such a designation does not necessarily mean a
faster regulatory review process or necessarily confer any
advantage with respect to approval compared to conventional FDA
procedures. Receiving Priority Review from the FDA does not
guarantee approval within the six-month review/approval cycle.
