QurAlis Receives Clinical Trial Authorisation (CTA) in European Union (EU) for QRL-201, a First-in-Class STATHMIN-2 Precision Therapy for ALS

EU CTA marks second regulatory clearance for Phase 1 ANQUR clinical trial of QRL-201 in ALS

ANQUR is first-ever clinical trial to evaluate a therapy that rescues STATHMIN-2 expression in ALS patients

QurAlis recently announced first patient dosed in Canada; enrollment completed in Cohort 1 portion of ANQUR

CAMBRIDGE, Mass., June 6, 2023 /PRNewswire/ -- QurAlis Corporation, a clinical-stage biotechnology company developing breakthrough precision medicines for amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases with genetically validated targets, today announced that the European review has been completed for the Clinical Trial Regulation (CTR) and each participating country has issued a notice of acceptance for QRL-201 for the potential treatment of ALS. QurAlis expects to initiate the Phase 1 ANQUR clinical trial of QRL-201 in participating European Union (EU) countries by the fourth quarter of 2023.

“This EU Clinical Trial Authorisation marks the second regulatory clearance for QRL-201 as we execute our global strategy focused on bringing breakthrough precision medicines to patients with ALS and other neurodegenerative diseases,” said Kasper Roet, Ph.D., CEO and co-founder of QurAlis. “We believe QRL-201 has the potential to halt disease progression, which could transform the care and treatment of ALS. We are dedicated to ensuring efficient advancement of our ANQUR clinical trial so that we can fulfill our mission to make a meaningful difference in patients’ lives.”

QRL-201 is a first-in-class precision therapeutic product candidate aiming to restore STATHMIN-2 (STMN2) expression in ALS patients. ANQUR is the first-ever study to evaluate a therapy that rescues STMN2 expression in ALS patients. STMN2 is a well-validated protein important for neural repair and axonal stability and is the most significantly regulated gene by TDP-43 exclusively in humans. Its expression is significantly decreased in nearly all ALS patients and it is the most consistently decreased gene over all sporadic ALS patient data sets. QRL-201 rescues STMN2 loss of function in QurAlis ALS patient-derived motor neuron disease models in the presence of TDP-43 pathology.

The Clinical Trial Authorisation (CTA) in Europe is part of a global regulatory strategy established by QurAlis for the clinical development of QRL-201, which also includes a cleared CTA in Canada. QurAlis has completed enrolling patients in the Cohort 1 portion of the ANQUR clinical trial in Canada and recently announced the first patient has been dosed. Participating countries in the EU CTA include Germany, Belgium, the Netherlands, and Ireland.

About the ANQUR Clinical Trial
ANQUR (NCT05633459) is a first-in-human global, multi-center, randomized, double-blind, placebo-controlled multiple-ascending dose Phase 1 clinical trial designed to evaluate the safety, tolerability, and pharmacokinetics of QRL-201 versus placebo in patients with amyotrophic lateral sclerosis (ALS). The primary objective of the study is to determine the safety and tolerability of multiple doses of QRL-201 in people living with ALS. The ANQUR clinical trial is expected to include 64 study participants with ALS across sites in Canada, the European Union, U.S., and United Kingdom.

About STATHMIN-2 and TDP-43
STATHMIN-2 (STMN2) is a well-validated protein important for neural repair and axonal stability, the expression of which is significantly decreased in nearly all ALS patients. Also known as SCG-10, STMN2 is a protein essential for the stabilization of microtubules which form an important component of the cytoskeleton of cells and axons. STMN2 is highly expressed in human motor neurons, the cells that primarily degenerate in patients suffering from ALS. In animal models, STMN2 deletion was found to cause axonal degeneration and loss of muscle innervation, which is the primary functional deficit that leads to paralysis in ALS patients.

Using human neuronal stem cell models from ALS patients, QurAlis co-founder and former Harvard professor Kevin Eggan, Ph.D., discovered in 2019 that the expression of STMN2 is regulated by TDP-43. The Eggan Lab showed that loss of normal TDP-43 function leads to a highly significant decrease in expression of STMN2 and an impairment in neuronal repair which could be rescued by restoring STMN2 levels. These results were published in Nature Neuroscience.

In addition to nearly all ALS patients, TDP-43 pathology is also associated with approximately 50 percent of patients with frontotemporal degeneration (FTD), the second most common form of dementia; about a third of Alzheimer’s Disease patients; and up to seven percent of Parkinson’s disease patients.

There are currently no cures for ALS or FTD. Limited therapeutic options are available for ALS and FTD patients who are in desperate need for effective therapies.
