Press Release Details

WATERTOWN, Mass., Nov. 05, 2015 (GLOBE NEWSWIRE) -- pSivida Corp. (NASDAQ:PSDV), (ASX:PVA),  a leader in the development of sustained release, drug delivery products for treating eye diseases, today provided a Company update and announced financial results for its first fiscal quarter ended September 30, 2015.

Development of Medidur™ for posterior uveitis, pSivida's lead product candidate, advanced signifcantly in the first quarter of fiscal 2016.  pSivida now plans to file a New Drug Application (NDA) for Medidur based on six-month efficacy data from its two Phase III trials, rather than 12-month data from one trial and six-month data from the second, after the U.S. Food & Drug Administration (FDA) advised pSivida that this data will be acceptable for review by the agency. Because all patients in the first Phase III trial completed six months of follow-up in September 2015, pSivida now expects to report top-line results from the first Phase III trial in December 2015.  Enrollment in the second trial continues on schedule, with a planned NDA for Medidur in the first half of 2017. pSivida has begun discussions with the MHRA (Medicines and Healthcare Products Regulatory Agency) to determine the requirements for approval in the EU.

Top-line results from a three-year, ongoing investigator-sponsored study of low and high doses of Medidur showed a statistically significant reduction in recurrence of uveitis (p=0.014), which is also the primary endpoint in pSivida's Phase III trials, and a statistically significant improvement in visual acuity (p=0.014) at the last follow-up visit in eyes treated with Medidur compared to those that were not treated with Medidur (pSivida is studying only the low dose).  pSivida also reported that, in its first Phase III trial, only 5% more study eyes (2/3's of which received Medidur) experienced elevated intraocular pressure (IOP) (over 21 mm Hg) than the fellow non-study eyes (none of which received Medidur) at three months of follow-up.  Because initial IOP elevation is an indication of the likelihood of subsequent clinically significant IOP increases, a key safety measure, the minimal difference at three months suggests favorable results for the safety of Medidur in the Phase III trials. 

"We look forward to reporting the top-line results from our first Phase III trial, which we now expect to be available at the end of this year,"  said Paul Ashton, Ph.D., President and CEO of pSivida.

pSivida is working on expanding the use of its patented Durasert™ technology platform beyond ophthalmology. pSivida and Hospital for Special Surgery, the leading specialty hospital for orthopedics and rheumatology, have been collaborating to develop an implant for the treatment of pain associated with severe knee osteoarthritis (OA). This implant is comprised of a screw with an embedded Durasert device that is surgically implanted in the knee. The implant is designed to deliver a corticosteroid directly to the joint on a sustained basis to provide long-term pain relief and thereby delay or eliminate the need for knee replacement surgery. Following promising pre-clinical data showing maintenance of sustained drug levels in the knee, the principal investigator filed an investigational new drug (IND) application and is awaiting information from the FDA as to any additional requirements it may have for initiating the clinical trial. "Knee OA is the primary reason for knee replacement surgery, with over 700,000 performed last year in the U.S. alone. These numbers are expected to increase with projected increases in aging and overweight populations. The potential to provide sustained treatment of the pain associated with severe knee OA and avoid knee replacement with a simple implant procedure is very exciting," said Dr. Ashton.

pSivida continued to make good progress in its programs to use its Durasert technology to create treatments for additional chronic eye diseases age-related macular degeneration (AMD) and glaucoma, both of which have known drug treatments and represent very significant market potentials. pSivida initiated a pre-clinical program evaluating the use of Durasert to deliver off-patent or soon-to-be off-patent anti-cancer drugs that inhibit VEGF and PDGF to treat wet and dry AMD, the leading cause of vision loss in people age 60 and older.  pSivida also was successful in optimizing the ability of Tethadur to deliver antibodies in in vitro studies. "Higher molecule loading capacity and enhanced antibody stability are critical attributes for sustained antibody delivery to a small cavity like the eye for an extended period so we are very pleased with our success in achieving these attributes in the lab. We are moving on to confirmatory testing of Tethadur.  We are targeting INDs for both AMD and Tethadur products in the next year," said Dr. Ashton.

"We had $24.0 million in cash at September 30, 2015.  That should give us the capital resources to continue our planned product development programs, including our two Medidur trials, into early 2017, even without any potential future payments arising from ILUVIEN," said Dr. Ashton.

Results for the FY 2016 First Quarter.  Revenues for the quarter ended September 30, 2015 totaled $466,000 compared to $25.3 million for the prior year quarter. The decrease was primarily due to the ILUVIEN FDA approval milestone earned in September 2014.

Operating expenses for the three months ended September 30, 2015 totaled $5.4 million compared to $4.5 million a year earlier. The increase was primarily attributable to higher CRO costs for the Medidur clinical development program.

Income tax benefit of $41,000 for the three months ended September 30, 2015 compared to income tax expense of $226,000 for the three months ended September 30, 2014. The prior year quarter included $260,000 of federal alternative minimum tax expense based on projected U.S. taxable income for calendar year 2014, which was primarily attributable to the $25.0 million ILUVIEN FDA approval milestone. Refundable foreign research and development tax credits were earned in both periods.

Net loss for the quarter ended September 30, 2015 was $4.9 million, or $0.17 per share, compared to net income of $20.6 million, or $0.67 per diluted share, for the prior year quarter.

At September 30, 2015, cash, cash equivalents and marketable securities totaled $24.0 million.

About Posterior Uveitis. Posterior uveitis is a chronic, non-infectious inflammatory disease affecting the posterior segment of the eye, often involving the retina, which is a leading cause of blindness in the developed and developing countries. It afflicts people of all ages, producing swelling and destroying eye tissues, which can lead to severe vision loss and blindness. In the U.S., posterior uveitis affects approximately 175,000 people, resulting in approximately 30,000 cases of blindness and making it the third leading cause of blindness in the U.S.

Patients with posterior uveitis are typically treated with systemic steroids, but over time frequently develop serious side effects that can limit effective dosing. Patients then often progress to steroid-sparing therapy with systemic immune suppressants or biologics, which themselves can have severe side effects, including an increased risk of cancer. Medidur is designed to provide improved outcomes compared to standard of care, but with a significant reduction in side effects.

About Medidur Phase III Trials . pSivida is conducting two Phase III trials to assess the safety and efficacy of Medidur for the treatment of posterior uveitis. These are randomized, sham-controlled, double-masked trials. The primary endpoint of both trials is recurrence of posterior uveitis at six months, with patients in both trials followed for three years.  The first Phase III Medidur trial is fully enrolled with 129 patients in 16 centers in the U.S. and 17 centers outside the U.S. As the last 6-month follow-up visit for patients in this trial occurred in September 2015, top-line data is expected in December 2015. The second trial will enroll up to 150 patients in approximately 15 centers in India. We plan to seek FDA approval of Medidur based on 6-month data from the two Phase III trials and a short-duration utilization study of our redesigned proprietary inserter, together with data referenced from the Phase III trials of ILUVIEN for DME.
