FDA Authorizes Clinical Trial for CRISPR/Cas9 Therapy for LCA 10

Audio version:

Editas Medicine, a company developing gene-editing treatments, has received authorization from the US Food and Drug Administration to launch a clinical trial for its emerging CRISPR/Cas9 therapy for people with a mutation in the gene CEP290, which causes Leber congenital amaurosis 10 (LCA10). LCA causes severe vision loss or blindness at birth.

Michael Kalberer: Determined to Empower Others and Bring Hope

Audio version:

Long Island native Michael Kalberer has a knack for connecting with everyone around him, despite being born with cerebral palsy (CP), a disorder that affects a person’s ability to move and maintain balance. The condition can also cause vision loss. At the age of 12, Michael noticed issues with his depth perception and visual field, which resulted in a diagnosis that he was legally blind. At 33 years old, he was finally diagnosed, specifically, with Leber congenital amaurosis (LCA).

A Boy with No Boundaries

Audio version:

Last summer, Kai Wang devoured 12 audio books on science and engineering feats like the Golden Gate Bridge, atomic bombs, and the cotton gin. He listened to the books over and over — some as many as five times. One of his favorite titles was “Rocket Men,” a 400-page book for adults on Apollo 8, the first manned mission to the moon.  He finished it in a week.

Kai enjoys talking with his mom, Mina, about everything he learns and reads. But it’s not just banter for him — he’s often quizzing her to see what she knows.

Vision Improvements Reported in ProQR’s Clinical Trial for LCA10 Treatment

ProQR, a biotech company in the Netherlands, has reported vision improvements for patients in a Phase 1/2 clinical trial for QR-110, a therapy for people with Leber congenital amaurosis 10 (LCA10), which is caused by the p.Cys998X mutation in the CEP290 gene. The mutation is estimated to affect about 2,000 people in the Western world.

The company reported that 60 percent of subjects in the trial demonstrated improvements in visual acuity and their ability to navigate a mobility course. The treatment was also safe for patients.

ARVO 2018: Dr. Shannon Boye Reports on her Emerging Gene Therapy for LCA (GUCY2D)

At the annual ARVO research conference in Honolulu, I had an opportunity to talk with FFB-funded researcher Shannon Boye, PhD, University of Florida, about her advancement of gene therapy for Leber congenital amaurosis (GUCY2D mutations) toward a clinical trial.

FDA Committee Unanimously Recommends Approval for Spark’s RPE65 Gene Therapy – Final Decision Due in January 2018

Ashley and Cole Carper traveled from Little Rock, AR, to tell their family’s story at the FDA hearing.

Ashley and Cole Carper traveled from Little Rock, AR, to tell their family’s story at the FDA hearing.

Spark Therapeutics has taken a major step closer to gaining marketing approval for its vision-restoring gene therapy for people with RPE65 mutations causing Leber congenital amaurosis (LCA) and retinitis pigmentosa. At the conclusion of a public hearing on October 12, 2017, an advisory committee comprised of FDA-selected experts voted unanimously – 16 to 0 – to recommend approval. The FDA is due to make a final decision on marketing approval for the treatment, known as voretigene neparvovec, by January 12, 2018.

The event held at FDA headquarters included the presentation of trial results from Spark representatives, as well as compelling testimony from patients, family members, and industry stakeholders.

Twenty-four-year-old Katelyn Corey told hearing attendees that before receiving the treatment, her constant adaptation to dwindling vision didn’t leave time for much else in her life. But her circumstances changed dramatically in December 2013, after she received the RPE65 gene therapy in Spark’s Phase III clinical trial.

When scientists embark on developing a treatment for an inherited retinal disease, one of their first tasks is to identify or create a model of the condition. Disease models can be cells in a Petri dish, a genetically engineered mouse or rat, or larger animal such as a pig. Each type of model has its pros and cons, including cost and similarity of disease characteristics to those in humans.

The investigators then use the model to study how vision is lost — that is, they figure out which types of retinal cells degenerate, what is causing the degeneration, and how quickly the cells stop working. After they gain an understanding of the disease, researchers evaluate potential therapeutic approaches using the model as a testing platform.

The goal: Move a therapy into a human study.

VISIONS 2016 – Dr. Richard Weleber Receives FFB’s Highest Research Honor, Recognized in Touching Video

Dr. Richard WeleberConsidering all that Richard Weleber, M.D., has accomplished over four decades —
including leadership and oversight of clinical trials for emerging retinal-disease therapies and innovations in retina imaging and functional evaluation at the world-renowned Casey Eye Institute, Oregon Health & Science University — it comes as no surprise that he’s been given FFB’s Llura Liggett Gund Award for career achievement. Dr. Weleber became the 10th recipient of the Foundation’s highest honor, named after FFB co-founder Lulie Gund, during the opening lunch of the VISIONS 2016 conference.

For Rare Disease Day – The Many Benefits of Genetic Research

Rare Disease Day logoIt’s apropos that Rare Disease Day 2016 will be held on the rarest day on the calendar—Leap Day, February 29.

However, collectively, rare diseases are not uncommon. About 30 million Americans, nearly 10 percent of our population, are affected by one of 7,000 rare diseases. They’re an important public health issue, making it incumbent upon us to work hard to eradicate them.
