PSIVIDA ANNOUNCES POSITIVE RESULTS FROM THE TWO PHASE 3 FAME TRIALS
OF ILUVIEN IN PATIENTS WITH DIABETIC MACULAR EDEMA
More patients receiving either the High Dose or Low Dose Iluvien showed improvement in best
corrected visual acuity of 15 or more letters at 2 years compared to those receiving sham treatment.
This was statistically significant.
pSividas licensee, Alimera Sciences, plans to file New Drug Application (NDA) in the second quarter
of 2010.
WATERTOWN, MA - December 24, 2009 -- pSivida Corp. (NASDAQ: PSDV, ASX: PVA, FF:
PV3), a drug delivery company with two of the only three ophthalmic sustained release delivery
products approved by the FDA for treatment of back of the eye diseases, today reported top-line 24
month results from the Phase III FAME study of Iluvien for the treatment of Diabetic Macular
Edema (DME) being conducted by pSividas collaborative partner Alimera Sciences. The Company
will host a conference call and webcast today at 4:30pm Eastern Time (details follow below). More
detailed information is available in the Company's Form 8-K filed today with the Securities &
Exchange Commission.
The FAME study was designed as two Phase 3 pivotal clinical trials (Trial A and Trial B). 956 patients
with DME were enrolled and randomized to receive either a high dose Iluvien (0.45 @g/day), a low
dose Iluvien (0.23 @g/day) or a sham insertion. The primary efficacy endpoint for the FAME Study is
the difference in the percentage of patients whose best corrected visual acuity (BCVA) improved by 15
or more letters from baseline on the Early Treatment Diabetic Retinopathy Study (ETDRS) eye chart at
month 24 between the treatment and control groups.
Based on Alimeras analysis of the Full Analysis Set, as described by the International Conference on
Harmonization (ICH) Guidance E9 and adopted by the FDA, the primary efficacy endpoint was met
with statistical significance for both doses of Iluvien in each of Trial A and Trial B, as well as on a
combined basis, as shown below:
Trial A Trial B Combined
Individual % p-value Individual % p-value Individual % p-value
Control 14/95 14.7% -- 16/90 17.8% -- 30/185 16.2% --
Low
Dose
51/190 26.8% 0.029 57/186 30.6% 0.030 108/376 28.7% 0.002
High
Dose
51/196 26.0% 0.034 62/199 31.2% 0.027 113/395 28.6% 0.002
The Full Analysis Set includes all 956 patients randomized into the FAME Study, with data imputation
employed using Last Observation Carried Forward (LOCF) for data missing because of patients who
discontinued the trial or were unavailable for follow up. This data set is commonly referred to as the
"intent to treat" population.
In addition, both the low and high dose Iluvien showed greater numerical efficacy at month 24 than at
month 18, a requirement for approval with 24 month data.
Safety was assessed from all patients enrolled in the study. Intraocular pressure (IOP) increases to 30
millimeters of mercury (mmHg) or greater at any time point, a key adverse event studied in the trial,
were seen in 21.6% of the high dose patients and 16.3% of the low dose patients. Over the 24 month
period 5.1% of patients receiving the high dose and 2.1% of the patients receiving the low dose had
received a trabeculectomy (filter surgery) to reduce their eye pressure.
Based on these and other data, Alimera plans to file for approval of the low dose of Iluvien for the
treatment of DME in the second quarter of 2010, followed by registration filings in various European
countries and Canada. Submission of the NDA will be based on the month 24 safety and efficacy data
while the FAME Study will continue to month 36.
We are very encouraged by these data and look forward to our collaborative partner Alimera filing the
NDA for potentially the first ophthalmic drug therapy approved for DME, said Dr. Paul Ashton,
President and CEO of pSivida. These data further validate our drug delivery technology.
In addition to the analysis described above, as prospectively planned in the protocol, Alimera also
conducted several other analyses of the 24 month data. These included (a) an All Randomized and
Treated (ART) analysis of the 24 month data that includes data from all subjects randomized and
treated and imputes values for all missing data using the LOCF method and (b) a Modified ART
analysis that utilizes the ART population but excludes data collected subsequent to the use of
treatments prohibited by protocol (such as intravitreal injections of Avastin, Lucentis or triamcinolone
acetonide) with the last observation prior to protocol violation imputed to month 24 using the LOCF
method. The results of these separate analyses are described below:
By the ART analysis, in Trial A 26.8% of low dose patients and 26.2% of high dose patients gained 15
or more letters at 24 months compared with 14.7% of patients randomized to control (p = 0.029 and
0.032, respectively). In Trial B of the ART analysis 30.8% of low dose patients and 31.3% of high
dose patients gained 15 or more letters compared with 17.8% of control patients (p = 0.028 and 0.026,
respectively). The results for both doses in both trials were statistically significant. By the Modified
ART method, in Trial A 22.6% of patients in the low dose and 24.1% of patients in the high dose
gained 15 or more letters compared with 12.6% of control patients (p = 0.057 and 0.026, respectively).
Trial A was not statistically significant for either dose. In Trial B by Modified ART, 29.7% of patients
in the low dose and 29.3% of patients in the high dose gained 15 or more letters compared with 13.3%
of control patients (p = 0.004 and 0.005, respectively). The results for both doses were statistically
significant.
The FAME study protocol provides that the primary assessment of efficacy will be based on the
Modified ART dataset and that the other datasets will be considered secondary; the protocol did not
specify the Full Analysis Set as a dataset for analyzing the study. However, we believe that the FDA
will consider the Full Analysis Set to be the most relevant population for determining safety and
efficacy in Trials A and B.
We look forward to the continued benefits of our agreement with Alimera, including a $25 million
milestone payment that would be due on approval of Iluvien, profit participation on sales of Iluvien
and payment of the $15 million conditional note from Alimera. If the note is not paid by April 2010,
the annual interest rate increases to 20% (to be paid quarterly) and Alimera is to begin monthly
principal payments of $500,000, Dr. Ashton continued.
More detailed analyses will be presented in February 2010 at the Angiogenesis, Exudation and
Degeneration 2010 Meeting in Miami, Florida.

About the FAME Study
The Phase 3 FAME Study consists of two multi-center, randomized, double-masked trials for Iluvien
in sites across the United States, Canada, Europe and India. The two trials have identical protocols and
enrolled 956 patients across 101 academic and private practice centers. Patients in each trial were
randomly assigned to one of three groups in a 2:2:1 randomization, respectively. One group received a
high dose of Iluvien (an approximate initial 0.45 micrograms (@g) per day dose), a second received a
low dose of Iluvien (an approximate initial 0.23 micrograms (@g) per day dose) and the third group
received sham. The sham included all the steps involved in the insertion procedure with the exception
that patients in this group had a blunt inserter without a needle to apply pressure to the anesthetized eye
in order to simulate an insertion. This procedure mimics an intravitreal insertion and helps to maintain
proper patient masking.
In addition to comparing the incidence of improvement in BCVA of 15 letters or greater from baseline
between the treated and control arms, a numerical comparison of improvement of BCVA of 15 or more
letters versus baseline was made between the month 24 and month 18 data, within each treatment arm.
The results showed that the incidence of improvement at month 24 is numerically greater than that at
month 18. Submission of the NDA will be based on the month 24 safety and efficacy data while the
study will continue to month 36.
About DME
DME, the primary cause of vision loss associated with diabetic retinopathy, is a disease affecting the
macula, the part of the retina responsible for central vision. When the blood vessel leakage of diabetic
retinopathy causes swelling in the macula, the condition is called DME. The onset of DME is painless
and may go undetected by the patient until it manifests with the blurring of central vision or acute
vision loss. The severity of this blurring may range from mild to profound loss of vision. The
Wisconsin Epidemiologic Study of Diabetic Retinopathy found that over a ten-year period
approximately 19% of diabetics studied were diagnosed with DME. Based on this study and the
current U.S. diabetic population, Alimera estimates that there will be an incidence of approximately
340,000 cases of DME annually in the United States. As the population of diabetics increases, Alimera
expects the annual incidence of diagnosed DME to increase.
About Iluvien
Iluvien is an investigative, extended release intravitreal insert that Alimera is developing for the
treatment of DME. Each Iluvien insert is designed to provide a therapeutic effect for up to 36 months
by delivering sustained sub-microgram levels of fluocinolone acetonide (FA). Iluvien is inserted in the
back of the patients eye to a position that takes advantage of the eyes natural fluid dynamics. Iluvien
is inserted with a device that employs a 25-gauge needle, which allows for a self-sealing wound.
