Gene therapy is promising to provide treatments and potential cures for a long list of rare, genetic diseases. A key element of these therapies are the viral vectors that are used to deliver and insert the genetic material used to treat a patient. Guangping Gao, co-director of the Li Weibo Institute for Rare Diseases Research, director of the Horae Gene Therapy Center and Viral Vector Core, and pr...

Sanath Kumar Ramesh’s son Raghav was born with an ultra-rare and progressive disorder known as SSMD. The condition is caused by mutations in the GPX4 gene. There are only a handful of known patients with GPX4 mutations. In the past, most known cases resulted in death about a month after birth. Ramesh has moved with remarkable speed to find patients, raise money, and drive research. But he also rea...

In his new book, Emmy-winning news and documentary television producer Miguel Sancho recounts the efforts he and his wife Felicia Morton went through to get their son Sebastian diagnosed and treated for chronic granulomatous disease, a rare and deadly immunodeficiency. The book “More than You Can Handle: A Rare Disease, a Family in Crisis, and the Cutting-Edge Medicine that Cured the Incurable” fo...

The Innovative Genomics Institute; a partnership between the University of California, Berkeley and the University of California, San Francisco led by Nobel laureate Jennifer Doudna; is working to harness CRISPR-based genome editing to correct underlying mutations in monogenic diseases. The institute is initially focusing its efforts on sickle cell disease and a rare familial autoimmune disorder....

The economic burden of rare disease in the United States reached nearly $1 trillion in 2019, according to a new study from the Everylife Foundation for Rare Diseases. About 43 percent of that total is for direct medical costs. The balance includes such things as forced retirement, absenteeism, and presenteeism—the lost productivity of people who show up to work but are not fully functioning. We sp...

The ability to target the underlying cause of a disease and make a lasting correction makes gene therapy an attractive approach to treating neurodegenerative conditions. The advent of Zolgensma, a gene therapy for the treatment of the rare neurodegenerative condition spinal muscular atrophy, serves as a model for this approach. A recent review article in Nature Neuroscience looks at the advances i...

Poseida Therapeutics is perhaps best known for its immune-oncology cell therapy products, but the company’s platform technologies are also being used to develop a growing pipeline of gene therapy candidates. While the most advanced ones in its pipeline use viral vectors, newer candidates make use of a non-viral nanoparticle vector. This technology can increase the payload of the gene therapy, avoi...

Jazz Pharmaceuticals has been successful at building and commercializing a growing pipeline of therapies to treat rare neurologic conditions and hematologic cancers. Central to its strategy has been the use of acquisitions to build its pipeline. In fact, we should note that since recording this podcast, the company continued that approach with news that it would acquire GW Pharmaceuticals for $7.2...

CRISPR is a powerful editing tool, but it works best as a way to knock out genes rather than correct them. New approaches to gene editing, though, are providing the promise of more effective tools for addressing the underlying drivers of monogenic diseases. A recent study in Nature of an approach known as base editing in a mouse model of the ultra-rare genetic condition progeria, a disease that ca...

Arya Singh grew up with a child’s-eye-view of hospitals, operating rooms, and clinical trial sites. As someone with the rare and progressive neuromuscular disorder spinal muscular atrophy type 2, Singh knew what it meant to be isolated and frightened by both as a patient and a clinical trial participant. Now a student at Yale University with plans to pursue her interests in law and public policy i...

Glioblastoma is an aggressive and rare brain cancer. Though it is typically treated with surgery, radiation, and chemotherapy, the prognosis for patients is grim with only 10 percent of surviving at least five years. Plus Therapeutics is developing a pipeline of radiotherapies that are encapsulated in nanoliposomes. Through novel deliver and formulation of these therapies, the company believes it...

Patients’ data is critical to rare disease innovation, but it does little to help advance progress if it is not widely accessible to researcher. RARE-X is a nonprofit working to bust data silos through a federated data-sharing platform and empower rare disease patient communities to more easily gather, structure and securely share critical data through a common platform. We spoke to Nicole Boice,...

The genetic basis of sickle cell disease has been long understood, but it has only been recent that new treatments and a growing pipeline of therapies have emerged. The inherited blood disorder causes red blood cells to become crescent shaped, which restricts the flow in blood vessels and limits oxygen delivery to the body’s tissues leading to severe pain and organ damage. At the end of 2019, Glob...

At the end of November, the U.S. Food and Drug Administration approved Rhythm Pharmaceuticals Imcivree, the first therapy for chronic weight management in patients with certain genetic forms of obesity. The approval validates Rhythm’s approach to target a specific biological pathway common to a number of these conditions. We spoke David Meeker, CEO of Rhythm, about genetic obesities, the company’s...

Orchard Therapeutics founder and former chief scientific officer Bobby Gaspar took the helm of the gene therapy company in March to replace CEO Mark Rothera when he stepped down. Since taking over, Gaspar has led a restructuring of the company and narrowed the focus to prioritize what it saw as high-value programs including its gene therapy for metachromatic leukodystrophy, a rare and life-threate...

Tessera Therapeutics is seeking to move beyond gene editing and gene therapy to what it calls “gene writing.” The company said its technology can be used to change base pairs, make small insertions or deletions, and integrate entire genes into the genome. We spoke to Geoffrey von Maltzahn, co-founder and CEO of Tessera, about the company’s gene writing technology, how it works, and the potential f...

In November, the U.S Food and Drug Administration approved Eiger Biopharmaceutical’s Zokinvy, the first therapy to treat the ultra-rare disorder progeria, a genetic disease that causes premature aging. The approval of Zokinvy, which began life as a potential cancer therapy known as lonafarnib, shows the essential role patient organization can play in driving research and bringing together collabor...

The rare disease drug developer Retrophin has been through a number of changes in recent years including a new CEO, a late-stage failure of a key program, and the resolution of dueling lawsuits between it and its former CEO and convicted fraudster Martin Shkreli. Now with data from its lead experimental therapy sparsentan expected next year in two different rare kidney diseases, the company has ch...

While gene therapies provide great promise for people with rare, genetic diseases, the pursuit of these one-time treatments may not seem economically viable to commercial developers. In the case of ultra-rare conditions, the patient populations may be so small that it may not be possible for companies to recoup their investments, let alone make a profit. The nonprofit Columbus Children’s Foundatio...

Daniel de Boer became a biotech executive after his son was diagnosed with the genetic respiratory disease cystic fibrosis. He founded ProQR Therapeutics with an initial focus on developing RNA therapies to treat cystic fibrosis, but the company has since turned its attention to a group of rare, inherited retinal diseases that cause blindness. We spoke to de Boer, CEO of ProQR, about the evolution...

The economics of developing gene therapies can make it unattractive for biopharmaceutical companies to invest in bringing a gene therapy through development and to the market for ultra-rare conditions. But researchers at the National Center for Advancing Translational Sciences are working to develop a set of gene therapy vectors that can be used in multiple indications and eliminate the time and c...

Though there are only a handful of gene therapies on the market today, there is a robust and growing pipeline of these transformative medicines advancing toward market.
