About
Focused on Designing Meaningful Medicines
Quellis was founded to deliver best-in-class therapies to patients suffering serious rare diseases – and underserved by current treatment options. The Company is based in Boston, and is led by partners from the biotech incubator Viridian LLC in collaboration with team at biotech accelerator Xontogeny LLC, and with funding from the Perceptive Xontogeny Venture Fund. The Quellis team has deep experience in mAb discovery and development, company creation, and private and public biotech investment. Our shared goal is to create meaningful medicines for every disease we target.
The lead Quellis program targets a life-threatening and burdensome rare disease. Approved medications leave substantial unmet needs for these patients; Quellis is pursuing a product-focused hypothesis to discover a new molecule with best-in-class performance. The Company is currently optimizing several new monoclonal antibodies (mAbs) leveraging a validated mechanism of action. We are engineering these mAbs to include features intended to deliver greater value and improve patients’ lives. As part of these efforts, the Company plans to incorporate Xencor, Inc.’s Xtend™ Fc technology, for which the Company holds a target-exclusive license from Xencor. Xtend is a clinically proven antibody technology that provides for improved antibody half-life and thereby reduces the size and frequency of doses that patients require compared to a standard antibody drug candidate.

Edasalonexent (formerly CAT-1004) is an oral and small molecule experimental therapy being developed by Catabasis Pharmaceuticals to treat all forms of Duchenne muscular dystrophy (DMD).
How edasalonexent works
DMD is one of the most common types of muscular dystrophy. It primarily affects boys and leads to the progressive loss of muscle fibers. The condition is caused by a mutation that results in a lack of dystrophin protein production. This protein provides structure to muscle fibers and protects them against injury. Without dystrophin, muscle fibers get damaged at each contraction.
A signaling pathway called the NF-kappa B pathway is activated in DMD patients from infancy. This pathway is responsible for muscle fiber breakdown, and the failure to repair muscle injuries that are seen in DMD patients.
Edasalonexent inhibits NF-kappa B, blocking the pathway. Through this mechanism, it is thought that edasalonexent may be able to preserve muscle function in DMD patients.
Edasalonexent in clinical trials
A combined Phase 1/2 clinical trial (NCT02439216) called MoveDMD evaluated the safety, efficacy, and pharmacokinetics (how the treatment moves in the body) of edasalonexent in children with a genetically confirmed diagnosis of DMD. A total of 31 boys, ages 4 to 8, were enrolled.
Edasalonexent preserved muscle function and substantially slowed DMD disease progression through 60 weeks of treatment compared to placebo. Consistent improvements in all assessments of muscle function were observed after more than a year of treatment. Edasalonexent was well-tolerated with no safety signals observed in the trial.
A Phase 3 clinical trial to further test edasalonexent is now underway. This 52-week trial, PolarisDMD (NCT03703882), is a multi-center trial with test sites in the U.S., Canada, Asia, and Australia.
PolarisDMD aimed to recruit 125 boys, ages 4 to 7, who have not been treated with corticosteroids for at least six months. The study actually exceeded this recruitment target due to high demand and enrolled 130 participants and is no longer enrolling. Patients were randomized, 2:1, to receive either edasalonexent (100 mg/kg capsule) or placebo daily. Patients will have clinical visits every three months, and the study’s primary goal is to measure the change in North Star Ambulatory Assessment scores at one year. This includes tests that measure the time it takes the children to stand, the four-stair climb test, and the 10-meter walk/run test. The boys’ muscle strength and growth, as well as their heart and bone health, will also be assessed. No muscle biopsies or magnetic resonance imaging (MRI) will be required for this study. The trial is expected to conclude in June 2020.
After 12 months, patients will be invited to continue receiving edasalonexent, or begin treatment, in an open-label extension study, GalaxyDMD (NCT03917719). The study is open to patients involved in the MoveDMD or PolarisDMD trials or DMD-affected siblings of boys enrolled in those trials. GalaxyDMD will follow the participants for up to 104 weeks (2 years) and is expected to complete in June of 2020.
Other information
The U.S. Food and Drug Administration (FDA) granted edasalonexent orphan drug, rare pediatric disease, and fast track designations. The European Commission (EC) also granted the treatment orphan medicinal product designation for the treatment of DMD.
