Stem Cells in Ophthalmology Update 28: First Ophthalmic Stem Cell Treatment Recommended for Approval

On December 19th, the European Medicines Agency’s (EMA’s) Committee for Medicinal Products for Human Use (CHMP) recommended the stem cell product Holoclar (Chiesi Farmaceutici S.p.A.)  as a first-ever medicinal treatment for severe limbal stem cell deficiency, a condition caused by physical or chemical burns to the eye or eyes in adults, which can result in blindness.
The EMA has designated Holoclar as both an orphan medicine and an advanced therapy medicinal product, which enabled the manufacturer to receive free scientific advice and protocol assistance for drug development. The CHMP recommendation was based on an assessment by the expert (Read more...)

Stem Cells in Ophthalmology Update 27: ACT Interim Clinical Results Are Outstanding

Having treated 36 patients in two clinical trials for Stargardt’s Macular Dystrophy (SMD – 24 patients to date) and for dry Age-Related Macular Degeneration (AMD – 12 patients to date), Advanced Cell Technology reported the interim results obtained with 18 of these patients (9 in each trial) in the US-based studies. Both trials (NCT01345006 – Stargardt’s, and NCT01344993 – AMD) began in July 2011, giving the company up to three-year’s data for the earliest patients, and a median of 22 months followup for all. The interim results were reported in The Lancet, published online October 14, 2014 in: “ (Read more...)

Iluvien Update 8: Alimera Sciences Receives FDA Approval of Iluvien for Treatment of DME

After several attempts to gain approval for its NDA for Ilunien, the FDA has finally seen the light (after approval in the UK, Germany, and marketing or pending approvals in seventeen other EU countries).
I first began writing about Iluvien in July 2010 – see my comprehensive writeup about the technology behind this and other sustained delivery drug systems – Iluvien and the Future of Ophthalmic Drug Delivery Systems. In addition I have written about the products progress in seven updates, the latest in August 2012, Iluvien Update 7: Alimera Sciences to Re-File for FDA Approval of Iluvien for (Read more...)

Retina Revealed

Over the weekend, I read an excellent account of how the various parts of the retina work. Ben Shaberman, the senior science writer for the Eye on the Cure blog (Foundation Fighting Blindness), put together an easy to read and understand overview of what the various cell layers of the retina do and how they interact. Since the retina is the focus of most of what I write about, I asked Ben for his permission to reproduce the writeup in this space. Permission was granted and here is what he wrote:

Stem Cells in Ophthalmology Update 26: First Wet AMD Patient Treated With RPE Derived from iPS Cells

Earlier this week, it was reported that Masayo Takahashi, an ophthalmologist at the RIKEN Center for Developmental Biology (CDB) in Kobe had appeared in front of a 19-member health-ministry committee for the safety of the clinical use of stem cells. She was flanked by Shinya Yamanaka, the biologist who first created iPS cells. Yamanaka shared the 2012 Nobel Prize in Physiology or Medicine for his breakthrough and now heads the Center for iPS Cell Research and Application in Kyoto. Takahashi was seeking approval to implant a retinal pigmented epithelial (RPE) sheet made from induced pluripotent stem (iPS) cells into a (Read more...)

An Update on Avalanche Biotechnologies: A Potential Longer-Lasting Wet AMD Treatment?

There is breaking news this week about Avalanche Biotechnologies and I would like to share it, as well as a brief update on the clinical trial underway using their proprietary gene therapy approach to treating the wet form of AMD.
(Editors Note: For a comprehensive look at the company, its people, and technology, please take a look at my original writeup, placed online in late February 2012: A Novel Gene Therapy Approach to Treating the Wet Form of AMD: The BioFactoryTM From Avalanche Biotech.)
Now for the breaking news. On May 5th, in a joint announcement, Avalanche (Read more...)

A New Approach for Repairing/Rejuvenating Damaged Photoreceptors and Other Retinal Tissue for Restoring Vision

Over the past several years, I have written about new technologies for treating retinal diseases, including the use of drugs (Avastin, Lucentis and Eylea for wet AMD), laser treatment (Ellex’s 2RT – Retinal Regeneration, for dry AMD), and the use of stem cells and gene therapy for a wide range of ophthalmic diseases.

Earlier this year, I became aware of a new company, jCyte, who was investigating the use of retinal progenitor cells to replace damaged or destroyed photoreceptors to restore vision to those whose photorecptors had stopped working, especially in those with the latter stages of  retinitis pigmentosa (RP).

Reversing Retinal Cell Death With Inkjet Printing?

For the past several months, I have been working with Mark Hillen, the editor of The Ophthalmologist, in providing him with background information about stem cells and gene therapy used in ophthalmology to treat various retinal diseases. Articles, based on my information, along with material developed by Mark, have been published in past issues of his magazine. (Stem Cell Clinical Trials and Gene Therapy Clinical Trials.)

The Ophthalmologist is a new professional journal, published by Texere Publishing, for a target audience of ophthalmologists and industry professionals, mainly based in Europe.

The latest issue (February 2014) contains an (Read more...)
