Advanced Cell Technology, Inc. (OTCBB: ACTC), a regenerative medicine company based in Marlborough, Mass., announced on January 3 that the U.S. Food and Drug Administration (FDA) has cleared its Investigational New Drug (IND) application to treat dry age-related macular degeneration (AMD) using retinal pigment epithelial (RPE) cells derived from human embryonic stem cells (hESCs).
ACT is now permitted to launch a Phase 1-2 multicenter clinical trial to treat patients with dry AMD, the most common form of macular degeneration in the world.
There are no treatments available for this prevalent disease of an aging global population. According to the company, dry AMD, representing a substantial global market opportunity and afflicts between 10-15 million Americans.
Age-Related Macular Degeneration has two predominant forms, wet and dry. Dry AMD is the most common form, accounting for almost 90 percent of all cases. The progress of dry AMD includes a breakdown or thinning of the layer of RPE cells in the patient’s macula, the region at the center of the retina responsible for high acuity vision. Over time, the progressive loss of RPE cells and accompanying loss of photoreceptors can cause severe vision loss and even blindness.
“ACT is now the first company to receive FDA clearance for two hESC trials, and is now a true translational leader in the field of regenerative medicine,” said interim CEO Gary Rabin. “It marks a major step forward, not just within the stem cell sector, but, potentially for modern healthcare techniques. We plan to proceed into the clinic with both of our hESC-based programs as quickly as possible.”
The Phase 1-2 trial will be a prospective, open-label study that is designed to determine the safety and tolerability of the RPE cells following sub-retinal transplantation into patients with dry AMD. Twelve patients will be enrolled in the study at multiple clinical sites. Sites currently under consideration are the Jules Stein Eye Institute at UCLA, and the Ophthalmology Department at Stanford University School of Medicine. Additional sites may be considered.
“Dry AMD is the leading cause of blindness in individuals over the age of 55,” said Robert Lanza, M.D., chief scientific officer. “As the population ages, the incidence of AMD is expected to double over the next 20 years, further exacerbating this unmet medical need. Using our clinical-grade hESC lines, we are able to generate a virtually unlimited and reproducible supply of healthy RPE cells. Because only a small number of cells (50-200K) are needed to treat each patient, manufacturing and distribution of the therapeutic product is scalable with many similarities to the drug businesses that pharmaceutical companies understand well. Based on our animal model studies, we are very excited about the opportunity to treat patients. In a rat model of macular degeneration, we have seen a remarkable improvement in visual performance over untreated animals, without any adverse effects. We have also maintained near-normal function in a mouse model of Stargardt’s Disease, a form of juvenile macular degeneration. In addition to this trial, we plan to concurrently use our RPE cells in our Phase I/II Clinical Trial for Stargardt’s Disease, which received the green light from the FDA in November. We hope to see a similar benefit in both Stargardt’s Disease and Dry AMD patients.”
ACT’s dry AMD therapeutic program uses RPE cells derived from hESCs to replace the lost RPE cells in the patient’s eyes. ACT’s proprietary RPE cell manufacturing process is protected by a number of broad patents, as is the use of hESC-derived RPE cells for treating macular degeneration. While the initial portion of the clinical trial will focus on safety, in subsequent clinical trials the company hopes to demonstrate that the RPE cells injected into the retinal space will be capable of slowing or halting progression of the disease, and potentially even restoring some visual acuity to patients.
“It is estimated that over ten million Europeans suffer from age-related macular degeneration, representing a vast unmet need and a significant market opportunity,” commented Edmund Mickunas, vice president of regulatory affairs. “We are moving ahead aggressively to seek regulatory clearance from the European Medicines Agency to conduct clinical trials in Europe.”

Genetic Testing for AMD is here Today
by:Diana Shechtman OD FAAO & Steven Ferrucci OD FAAO
Age-Related macular degeneration (AMD) is a progressive disease and the leading cause of vision loss among the elderly, affecting central vision required for daily activities such as driving and reading. There are a number of factors affecting AMD, such as advanced age, smoking, UV exposure, overall health (that contribute to high blood pressure, obesity, diet) and family history. Many factors may be modified and yet others like genetics cannot. Although AMD may seem to be hereditary in some families and not others, genetics have been shown to contribute significantly to the disease. Multiple twin and sibling studies have collaborated to the familial nature of the disease. First-degree relatives of patients with AMD are at a significantly increased risk for the disease. Furthermore, large epidemiological studies have suggested a strong genetic risk factor for AMD. In fact, the risk of developing AMD increases 4 fold among patients with a positive family history. In 2005 a breakthrough occurred in the area of genetic research and AMD; Klein and associates discovered a strong link between AMD and certain genetic variants. Similarly, numerous other genes have been implicated in AMD, which may increase the risk of AMD up to 70%.
Until recently there was no test to help determined patient’s inherited risk for AMD. Today, Macula Risk (ArcticDX, Toronto, Ontario) is a genetic test specifically designed to determine genetic predisposition to AMD and vision loss attributed to the more advanced stage of the disease.
Macula Risk genetic test separates individuals into one of 5 macula risk (MR) categories, with MR 3 through 5 representing an increased risk for the more advance stage of the disease. This accounts for approximately 20% of the general population. MR1 has less than a 5% risk of the advanced stage of the disease, while MR 5 carries greater than 55% risk. These results can aid the doctor in devising a specific management plan and follow-up protocol in order to reassure early intervention to prevent vision loss.
The test only requires a simple in-office cheek swab, which is sent directly to the genetic lab. The report includes test results and written genetic support information (including access to genetic counseling). Macula Risk genetic testing is covered by most insurance providers, including Medicare, as long as the specific diagnosis (ICD-9) are identified by the doctor. The prognostic genetic test is intended for patients who have a diagnosis of early or intermediate AMD. Thus, the “at risk patient,” would have to pay a fee for the test.
Despite our best efforts and new treatment options available today, many people are still losing vision from AMD. New advancements in the area of AMD are becoming an integral part in preventing future visual deterioration. AMD is affected by both environmental and genetic factors that interact with one another to determine prevalence and progression of the disease. Furthermore, at this time we do not know all of the genes linked to AMD. Hence, genetic testing in the area of AMD is only a risk indicator and cannot predict “without a shadow of a doubt,” which patients will and which will not develop the disease. However, this test provides a genetic profile screening to help identify those at risk as well as aids in tailoring a distinct management approach for those with the disease. With various researches devoted to treatment options for AMD, genetic testing in the area of AMD is at the frontier of providing crucial information.

The link Between Age-Related Macular Degeneration and Cardiovascular Disease
by:Johns Hopkins Health Alert
Several studies have found that people with age-related macular degeneration (AMD) are more likely to have heart disease than those without age-related macular degeneration. A U.S. Medicare study, for example, found that elderly people with age-related macular degeneration were 20% more likely to have a heart attack than their counterparts who didn't have age-related macular degeneration. And a large Australian study, reported in the British Journal of Ophthalmology, suggests that age-related macular degeneration increases the risk of dying from coronary heart disease or stroke.
The researchers used data from nearly 3,000 participants, age 49 and older, in the Blue Mountains Eye Study -- none with a history of coronary heart disease or stroke at enrollment. They found that people younger than age 75 who had early signs of age-related macular degeneration at the study's start were twice as likely to die of coronary heart disease as their counterparts who did not have early signs. However, there was no increased risk of dying of a stroke in this group.
People with late age-related macular degeneration at the beginning of the study who were under age 75 had five times the risk of dying of coronary heart disease and 10 times the risk of dying of a stroke. The link between late age-related macular degeneration and risk of death from cardiovascular disease should be interpreted cautiously, warn the researchers, because there were so few people with late age-related macular degeneration at study entry.
Surprisingly, the researchers found no increased risk of death from cardiovascular disease among people over age 75 with age-related macular degeneration. They speculate that past 75, patients died of other serious health conditions that overshadowed the connection.
Take-away message: What's behind the link between age-related macular degeneration and cardiovascular disease? Some researchers suspect that age-related macular degeneration and cardiovascular diseases may share a common genesis: for instance, atherosclerosis, inflammation, and oxidative stress (the cell damage caused by free radicals) are known to affect both conditions. Another alternative: age-related macular degeneration may simply be a disease of aging.

DeGette Hails Approval of Second Embryonic Stem Cell Human Trial
by:PoliticalNews
Congresswoman Diana DeGette (CO-01) hailed the approval of the second human treatment trial using human embryonic stem cells. The test, just approved by the FDA, will be conducted by Advanced Cell Technology (ACT) and will focus on Stagart disease. Medical professionals believe a successful human trial will open the doors to the treatment of other, more common eye diseases such as macular degeneration. DeGette has been the leading Congressional advocate for federal funding of ethical embryonic stem cell research, as these investments drive breakthrough trials like the one announced this week.
“Embryonic stem cell research holds enormous promise for countless diseases,” said DeGette, “and the approval of this test is yet another step towards the breakthroughs it can bring for millions of Americans. I am excited to see the results of this, and other trials, and encourage my colleagues to recognize the enormous benefits of ethical embryonic stem cell research.”
Stagart’s disease affects central vision – e.g., reading and facial recognition – and can cause its victims to lose peripheral vision, only be able to see various levels of light, or ultimately go blind. This test will treat Stagart’s patients with healthy cells, created from embryonic stem cells, to replace the “scavenger cells” that deteriorate their vision.
The test is the second trial using embryonic stem cells to be approved in the United States. Last month, the Geron Corporation was permitted to conduct a trial involving embryonic stem cells to treat spinal cord injuries. Preliminary testing is still ongoing in that trial. Like the Geron trial, this latest trial will focus primarily on the safety and viability of embryonic stem cell use in the treatment of this condition. The Stagart’s trial will likely start early next year and 12 subjects will be treated.
“The approval of these two tests in such close order demonstrates how the investment by the federal government in ethical stem cell research is beginning to bear fruit for the millions of Americans facing debilitating diseases and conditions,” said DeGette. “The breakthroughs of these discoveries underscore the critical importance of finally codifying ethical stem cell research regulations, so our scientists and their critical work can no longer be subject to political whims.”

UC Santa Barbara Part of International Research Collaboration Focusing on Age-Related Macular degeneration Cure
By AScribe Newswire
SANTA BARBARA, Calif., Nov. 15 - An international collaboration between UC Santa Barbara, the Keck School of Medicine of the University of Southern California (USC), and several other research institutions, is bringing together leaders in the fields of stem cell biology, basic science, and ophthalmology to develop a treatment for blindness caused by age-related macular degeneration.
The California Project to Cure Blindness (CPCB) was formed with a $16 million California Institute for Regenerative Medicine (CIRM) "disease team" grant awarded in late 2009 to fund development of a stem cell-based treatment for age-related macular degeneration. As part of the CIRM Disease Team partnership program, an additional $4.1 million from Britain's Medical Research Council funds collaborative work at University College of London.
"UCSB scientists in the Center for Stem Cell Biology and Engineering and the Center for the Study of Macular Degeneration are excited to provide the basic research that will allow translation of stem cell research to the clinic," said Dennis Clegg, professor in UCSB's Department of Molecular, Cellular, and Developmental Biology, and co-director of the UCSB Center for Stem Cell Biology and Engineering. Both centers are part of UCSB's Neuroscience Research Institute. Grant funds totaling $2.5 million for this work were assigned to UCSB through USC.
The overall grant was awarded to principal investigator Mark Humayun, professor of ophthalmology, cell and neurobiology and biomedical engineering at the Keck School, and David R. Hinton, professor of pathology and ophthalmology at the Keck School. Co-investigator is Martin Pera, director of the Eli and Edythe Broad CIRM Center for Regenerative Medicine and Stem Cell Research at USC.
"With this collaboration, we hope to accelerate research on a stem cell-based therapy for age-related macular degeneration," said Humayun. "Age-related macular degeneration is the leading cause of irreversible vision loss, affecting one in three people age 75 or older. The CIRM grant enables us to work with numerous researchers and experts who are dedicated to finding the cure to this devastating medical condition."
The cause of blindness in age-related macular degeneration is the death of retinal pigment epithelial cells, which provide critical support of photoreceptor function and health. The project objective is to replace damaged retinal epithelium with healthy tissue derived from human embryonic stem cells to prevent loss of vision.
Stem cell therapy offers the possibility of a wider range of options for age-related macular degeneration patients, said Keck School Dean Carmen A. Puliafito. "While exciting new pharmaceuticals to treat age-related macular degeneration are now available, these are effective only in a select group of patients, and can be used only during a narrow time window," said Puliafito, an ophthalmologist whose academic focus is macular degeneration. "In contrast, stem cell therapy promises to be broadly applicable. The potential is tremendous."
CIRM President Alan Trounson noted that the disease team approach exemplified by the California Project to Cure Blindness could transform the direction of future research.
"Scientists have talked for years about the need to find ways to speed the pace of discovery," said Trounson. "CIRM, through the Disease Team Award Program, has encouraged applicants to form teams composed of the best researchers from around the world. The partnership between the California Project to Cure Blindness and Britain's Medical Research Council is a great example of CIRM's vision of a new standard for funding translational research."

CIRM to dole Out $72M to Advance Research and Recruit Stem Cell Scientist
The California Institute for Regenerative Medicine (CIRM) approved funding for 19 awards worth $67 million under the Early Translation II Awards program. The 29-member governing board also voted to approve the second Research Leadership Award of $4.8 million, given to aid in recruiting Peter Coffey, D.Phil., from the University College London to the University of California, Santa Barbara.
The Early Translation II Awards are the second of what CIRM expects to be a 12- to 18-month award cycle for translational research grants. The funded projects are expected to either result in a candidate drug or cell therapy or make significant strides toward such a candidate.
“We are looking for ways to complement our leading edge of stem cell-based treatments for patients, and these projects will load our frontline portfolio with promising studies on autism, muscular dystrophy, Canavan disease, and liver disease,” says Alan Trounson, CIRM president.
The awards went to one for-profit and 11 not-for-profit institutions. The for-profit company iPierian will take its award in the form of a loan. Three of the awards include collaborators in Germany. The portion of the projects carried out by these collaborators will be supported by the Federal Ministry of Education and Research, the science financing agency in Germany, which will fund up to $15 million for this round of awards.
The $4.8 million grant under the Research Leadership Award program will be spread over six years and will back Dr. Coffey’s research on maturing embryonic stem cells into retinal pigment epithelial cells to treat macular degeneration and other forms of vision loss such as diabetic retinopathy and retinitis pigmentosa. Dr. Coffey is part of a team working toward a therapy for macular degeneration led by Mark Humayun, M.D., Ph.D., at the University of Southern California.
“Recruiting internationally renowned stem cell experts such as Dr. Coffey builds a critical mass of stem cell leadership in California to drive the creation of innovative therapies for patients suffering from chronic disease or injury,” notes Robert Klein, chair of the CIRM governing board.

AstraZeneca joins UCL to find stem cell cure for diabetic blindness
* Julia Kollewe
12 September 2010
AstraZeneca and University College London (UCL) will announce a research partnership tomorrow to develop medicines that use stem cells to repair damaged eyesight in people with diabetes.
Under the three-year deal funded by the drugmaker, researchers from AstraZeneca will team up with scientists at the UCL Institute of Ophthalmology to work on new medicines that use the regenerative capacity of stem cells. They hope to come up with a compound in three to five years, which could then undergo clinical development and possibly be on the market in 10 years' time.
Dr Marcus Fruttiger of the UCL Institute of Ophthalmology, who is leading the project, said: "These tools could be used either to manufacture transplantable material or to directly stimulate new cell growth in the eye to help restore or improve the vision of those with diabetic retinopathy [DR]."
DR is now the most common cause of vision impairment or blindness among western people of working age. The majority of patients with type-1 diabetes, which occurs when the body produces no insulin and often develops during the teenage years, will suffer eyesight problems and about 20%-30% will become blind. Moreover, at least 50% of patients with type-2 diabetes – the far more common type of diabetes, which occurs when the body produces too little insulin or when cells in the body do not react properly to insulin – will also develop retinopathy over time.
With the rapid spread of type-2 diabetes, which is linked to obesity, the need for a retinopathy treatment will grow as more than 438 million people are expected to suffer from diabetes by 2030. A study published this year by Oxford University predicted that eight out of 10 men and almost seven in 10 women will be overweight or obese by 2020. It forecast a 98% rise in obesity-related diabetes by 2050.
Alan Lamont, director of sciences and technology alliances at AstraZeneca. said: "We're getting very keen on the whole area of regenerative medicines and they will be part of our research development over the next few years." He said the collaboration aimed to come up with a treatment that could be administered to the back of the eye to repair damage locally.
AstraZeneca's US rival Pfizer also has a partnership with Professor Pete Coffey of the UCL Institute of Ophthalmology, for another eye condition, macular degeneration. Coffey said: "It's great that 'Big Pharma' is considering regenerative medicines as a serious possibility." He added: "This is British science being developed into a commercial entity with the pharmaceutical industry. It's a good example why the government shouldn't cut funding for biomedical research."
While this is the first time that AstraZeneca has worked on medicine for retinopathy, diabetes has been an area of focus. The company has a new diabetes treatment on the market called Onglyza, which was developed with Bristol-Myers Squibb, and the companies are developing a second diabetes drug that could be submitted to regulators for approval later this year.

Federal stem cell ruling blocks Yale scientists
By Rachel Gilmore
For two decades, Lawrence Rizzolo, the director of medical studies at the Yale School of Medicine, has been working toward a project that aims to transplant young, healthy retinal cells to replace diseased tissues in the eyes of patients who are going blind.
But now Rizzolo fears he may have to delay, or even stop, his research because of last week’s ruling by a federal judge that prevents federal funding for studies involving embryonic stem cells, the building blocks for human organs and tissues that Rizzolo needs for his project.
Rizzolo had applied for a grant from the National Institutes of Health to replace his funding from the nonprofit International Retinal Research Foundation, which ends in December. Rizzolo also has a three-year state grant from Rocky Hill, Conn.-based state holding company Connecticut Innovations, but he says he cannot continue his research without the federal funding.
Rizzolo’s laboratory is one of about a dozen facilities on campus that use stem cells. Haifan Lin, director of the Yale Stem Cell Center, said he did not yet know how the moratorium will affect Yale researchers.
“We’re all waiting for clarification on the implications of the judge’s ruling,” University President Richard Levin said.
But frozen funding could lead scientists to lose their jobs. Rizzolo said that although a fourth researcher will join his laboratory in October, he may soon have to fire his workers because the grants and not the University pay for his researchers’ salaries.
Although the U.S. Department of Justice has filed a motion seeking to delay the federal judge’s ban on funding, the relief would only be temporary, NIH spokesman Don Ralbovsky said. The Justice Department declined to comment Thursday.
Opponents of embryonic stem cell research have hailed the ruling.
“The American people should not be forced to pay for experiments — prohibited by federal law — that destroy human life,” said Steven Aden, the legal counsel for the Alliance Defense Fund, which advised the party that brought the lawsuit to court.
Most labs at Yale’s Stem Cell Center are supported primarily by state funds, which are not affected by the ruling, said Diane Krause, the center’s assistant director. But, she explained, those state grants were meant to be a springboard for acquiring federal funding.
“Discontinuation of NIH funding of work with human embryonic stem cells could be a disaster,” she said.
School of Medicine Dean Robert Alpern agreed, saying that halting the stem cell research would be a “loss to society.”
Krause and other Yale researchers met Aug. 26 with Connecticut attorney general and U.S. Senate candidate Richard Blumenthal LAW ’73, who told the News this week that he plans to file a brief in support of the appeal.
“It is incredibly important for our scientific and legislative leaders to come together and solve this issue quickly,” Blumenthal said in a statement. “We have already lost so many years of work to backwards-looking and bureaucratic federal policy.”
Linda McMahon, his Republican challenger for Chris Dodd’s Senate seat, also supports stem cell research, according to her website. The McMahon campaign did not respond to multiple phone requests for comment this week.
Even if the Justice Department successfully delays the ruling, NIH has not said whether it would accept new applications. That would be a problem for Yibing Qyang, an assistant professor of cardiology at the School of Medicine who currently has a $95,499 federal grant and had planned on applying for another in October.
“I cannot live without federal funding,” said Qyang, who is priming stem cells to become healthy heart cells in patients with heart disease.
Yale has received at least $17 million in state funding from a $100 million stem cell research pot funded in part by tobacco taxes. It also received $4.9 million in NIH stem cell research grants in 2009 and 2010. NIH gave $123 million to researchers in fiscal year 2010 for embryonic stem cell research, Ralbovsky said.
Rizzolo studies eye tissues called retinal pigment epithelia. Many eye diseases — including macular degeneration, from which more than 10 million Americans suffer — affect these tissues, which function as a support for the retina, the part of the eye responsible for sight. Doctors have tried to transplant retinal and epithelial cells to combat these diseases. But most of the transplants fail because they are risky and the patients who choose to undergo them are usually almost blind. Patients in the early stages of macular degeneration are unlikely to attempt a transplant; Rizzolo said he hopes that his research with stem cells, which he started to use about a year ago, would lead to other, less risky, treatments for the disease.
Rizzolo added that, in the past year, two Yale colleagues had entirely shut down their stem-cell research labs because of funding shortages.
“It’s pretty frustrating when you work so hard to see something go unfunded for political reasons,” he said.
The Yale Stem Cell Center, established in 2006, brings together more than 30 faculty members across the University.

International Stem Cell Corporation Formalizes Stem Cell- Based Eye Care Programs Into Cyovis
Article Date: 22 Aug 2010
International Stem Cell Corporation (OTCBB:ISCO), announced that its stem cell therapeutic programs focused on protective, transparent corneas (CytoCor™) in the front of the eye and the light-sensitive retinal tissue (CytoRet™) in the back of the eye will be formalized into a new business unit, Cytovis™. Together these programs will leverage external and internal development, regulatory and commercial expertise in cellular ophthalmology to form a focused portfolio of complementary product candidates designed to address high unmet medical needs with apparent pharmacoeconomic and quality of life benefits.
CytoCor is the brand name for ISCO's corneal tissue that can be derived from the company's proprietary parthenogenetic stem cells or commonly used embryonic stem cells. Research and development with partners Absorption Systems in the US, Sankara Nethralaya in India and Automation Partnership in the UK continues for the purpose of optimizing the tissue for transplantation in the 10 million people worldwide suffering from corneal vision impairment and as an alternative to the use of live animals and animal eyes in the $500+M market for safety testing of drugs, chemicals and consumer products. ISCO's goal in the coming months is to establish funding and infrastructure in India for accelerated development of CytoCor for the therapeutic application and to advance and implement the chemical testing application with partners in the US and Europe.
CytoRet is the brand name for ISCO's stem cell-derived retinal tissue. ISCO is using its parthenogenetic stem cells to develop individual retinal pigmented epithelial ("RPE") cells and layered retinal structures internally and in collaboration with the laboratory of Dr. Hans Keirstead, Professor of Anatomy and Neurobiology at the University of California, Irvine. ISCO recently commenced a new research collaboration with UC Irvine to launch the next phase of its retinal studies with that institution, including preclinical trials. Potential therapeutic applications include retinitis pigmentosa, an untreatable inherited disease affecting about 100,000 Americans, and the dry form of age-related macular degeneration, a major cause of blindness in the elderly of the Western world. ISCO's goal is to establish functional proof of concept for RPE cellular therapy in models of human disease in the next twelve-eighteen months.
Jointly referred to as Cytovis ("cyto" for cellular, "vis" for vision), these two cellular ophthalmology programs share a number of features and benefits. First, with the aging of the population worldwide and the growing number of work-related eye injuries in India, China and other major countries, the market opportunity is growing steadily. Second, there are strong pharmacoeconomic and quality-of-life rationales for full or partial vision restoration or delay of vision impairment diseases. Third, delivery of cells and tissues to the confined anatomy of the eye inherently provides for better safety and efficacy than, for example, the systemic circulation or the central nervous system. This will likely result in lower regulatory barriers and shorter and less costly development paths compared to that of anatomically deeper and more widespread diseases. Fourth, a number of eye diseases cannot be treated with surgery or traditional small molecule or protein therapeutics, yet cell and tissue therapy is proven to work but currently limited by availability of safe and sufficient cells and tissue from human donors. Finally, eye care development programs like CytoCor and CytoRet share a number of regulatory, development and commercial aspects that make it feasible for a relatively small team to produce substantial clinical outcomes and achieve competitive presence in the marketplace alone or in collaboration with dedicated partners.
Brian Lundstrom, ISCO's President, says: "ISCO's proprietary parthenogenetic stem cell technology continues to form the foundation for the company's long term regenerative medicine therapy programs. In the nearer term, CytoCor and CytoRet's unique benefits in the field of cellular ophthalmology offer the potential for partnering and funding at a relatively early stage. Combined with the current and future revenue of Lifeline Cell Technology and the revenue potential of Lifeline Skin Care, scheduled for launch in the 4th quarter, Cytovis adds significantly to ISCO's diversity and value creation potential for its investor base in a cost-efficient fashion."

Potential therapeutic applications include retinitis pigmentosa, an untreatable inherited disease affecting about 100,000 Americans, and the dry form of age-related macular degeneration, a major cause of blindness in the elderly of the Western world. ISCO's goal is to establish functional proof of concept for RPE cellular therapy in models of human disease in the next twelve-eighteen months.
Jointly referred to as Cytovis ("cyto" for cellular, "vis" for vision), these two cellular ophthalmology programs share a number of features and benefits. First, with the aging of the population worldwide and the growing number of work-related eye injuries in India, China and other major countries, the market opportunity is growing steadily. Second, there are strong pharmacoeconomic and quality-of-life rationales for full or partial vision restoration or delay of vision impairment diseases. Third, delivery of cells and tissues to the confined anatomy of the eye inherently provides for better safety and efficacy than, for example, the systemic circulation or the central nervous system. This will likely result in lower regulatory barriers and shorter and less costly development paths compared to that of anatomically deeper and more widespread diseases. Fourth, a number of eye diseases cannot be treated with surgery or traditional small molecule or protein therapeutics, yet cell and tissue therapy is proven to work but currently limited by availability of safe and sufficient cells and tissue from human donors. Finally, eye care development programs like CytoCor and CytoRet share a number of regulatory, development and commercial aspects that make it feasible for a relatively small team to produce substantial clinical outcomes and achieve competitive presence in the marketplace alone or in collaboration with dedicated partners.
Brian Lundstrom, ISCO's President, says: "ISCO's proprietary parthenogenetic stem cell technology continues to form the foundation for the company's long term regenerative medicine therapy programs. In the nearer term, CytoCor and CytoRet's unique benefits in the field of cellular ophthalmology offer the potential for partnering and funding at a relatively early stage. Combined with the current and future revenue of Lifeline Cell Technology and the revenue potential of Lifeline Skin Care, scheduled for launch in the 4th quarter, Cytovis adds significantly to ISCO's diversity and value creation potential for its investor base in a cost-efficient fashion."

Researchers create retina from embryonic cells
By Adrian Galbreth
Researchers in the US have successfully created a retina from human embryonic stem cells, which offers hope to millions with degenerative eye disorders.
Experts at the University of California Irvine created an eight-layer, early stage retina from human embryonic stem cells, which is the first ever three-dimensional tissue structure to be made from stem cells.
Study leader Hans Keirstead of the Reeve-Irvine Research Center and the Sue and Bill Gross Stem Cell Research Center at the facility, said the process also marks the first step towards the development of transplant-ready retinas to treat conditions such as retinitis pigmentosa and macular degeneration, a leading cause of blindness.
"We made a complex structure consisting of many cell types. This is a major advance in our quest to treat retinal disease," he explained.
Recently, German research centre Fraunhofer-Gesellschaft claimed that a new implant made of plastic could soon offer patients the chance to see again without having to wait for cornea transplants.ADNFCR-1853-ID-19804594-ADNFCR
