When Stealth Biotherapeutics sought approval for its experimental therapy to treat the ultra-rare and life-threatening condition Barth syndrome, the U.S. Food and Drug Administration said it wouldn’t review its application because the clinical studies the company performed involved too few patients to make a determination about the efficacy of the drug. The notice was part of a history of interact...

Primary mitochondrial myopathies are a group of rare, often life-threatening disorders caused by genetic mutations that affect the energy needs of skeletal muscles and can impact the ability to walk, lift, or do other everyday activities. High energy tissues like the heart, brain, and muscle are most affected by these disorders. Currently, there are no approved drugs to treat people with these con...

In neurodegenerative diseases like ALS, cells in the brain suffer a decline in their ability to produce energy. These impairments help to drive the progression of these diseases. Clene Nanomedicine is developing a nanocrystal suspension of gold atoms that are small enough to enter mitochondria—the cellular organelles that power activity—to increase two critical energy metabolites to fuel cellular...

One of the greatest challenges emerging therapies face is being able to reach the tissues and cells in the body where they need to go to provide benefit. Rather than using viral vectors or lipid nanoparticles, Evox is harnessing exosomes, a natural transporter within the body, to carry therapeutic cargo to desired targets. The company has developed platform technology to modify exosome so it can l...

Though enzyme replacement therapies have proven a viable strategy for treating lysosomal storage disorders, one problem is that these medicines face challenges reaching all of the cells throughout the body that are affected by these conditions, particularly in the brain. Avrobio is developing one-and-done gene therapies to treat cystinosis and other lysosomal storage disorders to overcome the limi...

Around the time Deb Scharper’s husband Tommy turned 38, he became forgetful, started to act odd, and lost interest in his long-time passion of driving and repairing cars. He grew paranoid and eventually suffered a breakdown in which he sought to harm his children and himself. The family had him admitted to a psychiatric facility and he was diagnosed and treated for depression. It would take until...

Hypoparathyroidism is a rare condition that is caused by the lack of functional parathyroid glands. The condition can lead to a long list of complications including muscle pain, brain fog, and damage to the kidneys. Amolyt Pharma is developing a therapeutic peptide to treat hypoparathyroidism. We spoke to Mark Sumeray, chief medical officer of Amolyt, about what its like for people living with the...

In 2022, three gene therapies for rare conditions won approval in the United States. As these and other advanced therapies make it to market, drug companies and payers need to wrestle with pricing issues, particularly for one-and-done therapies that are potentially curative. We spoke to Alice Valder Curran, partner with Hogan Lovells, about the challenges of value-based pricing for gene therapies,...

The transformational potential of AAV gene therapies has been limited by challenges of delivering genetic material to the cells where they need to go, gene expression, immunity, and the complexity of manufacturing them. Apertura Gene Therapies is seeking to simultaneously engineering AAV capsids, genetic regulatory elements, and payloads to overcome these limitations. We spoke to Joseph La Barge,...

In October, Alnylam said it would halt development of a therapy for a rare eye disorder to evaluate the impact of the Inflation Reduction Act. The decision is a reflection of the unintended consequences that policies can have on rare disease drug development. We spoke to Amanda Malakoff, executive director of the Rare Disease Company Coalition, about the policy landscape for rare disease therapies...

In December 2020, Ovid Therapeutics’ experimental therapy OV101 for the rare, neurodevelopmental condition Angelman Syndrome failed to meet its primary endpoint in a phase 3 clinical trial and the company chose to discontinue development. But rather than let the data from the study languish on the shelf, Ovid made the decision to contribute it to the Angelman Syndrome Foundation’s LADDER database....

Fabry disease is a progressive disorder that affects organs throughout the body including the heart, kidneys, and nervous system. People with the condition may suffer for years before obtaining a diagnosis. Jack Johnson, who co-founded the Fabry Support and Information Group, traced Fabry disease back more than five generations in his family. We spoke to Johnson about his own experience with the c...

Racial disparities in care and outcomes have been well documented but the problems can be particularly acute in cases of rare, genetic diseases. One example of this is the rare blood cancer cutaneous T-cell lymphoma. African Americans are twice as likely as people of European or Asian descent to develop CTCL, are typically diagnosed with more advanced disease, and have a lower survival rate from t...

Just three years after Children’s Mercy Research Institute launched its Genomic Answers for Kids program, it reported that it had hit the milestone of providing 1,000 rare disease diagnoses to families. One reason for the success of the GA4K program has been the use of advanced genomic sequencing that captures the full genome and methylome to reveal part of the human genome that has never been cli...
