Phase 3 Trial of Oral Levosimendan as Respiratory Treatment for ALS Recruiting in US, Europe and Australia

July 10, 2018 - als

A new Phase 3 hearing evaluating levosimendan (also famous as ODM-109), an verbal diagnosis by Orion for respirating problems in amyotrophic parallel sclerosis (ALS), has recruited a initial patients, a Finnish curative company announced.

The trial, called REFALS (NCT03505021), aims to examine a intensity advantages of enlarged diagnosis with levosimendan on respiratory muscles in ALS patients. The therapy is approaching to assistance hindrance a decrease in patients’ ability to exhale and check a need for movement support.

REFALS aims to partisan 450 patients during sites in North America, Europe, and Australia. They will be incidentally reserved to accept possibly levosimendan, administered in 1 mg verbal capsules, or remedy once to twice a day for 48 weeks (11 months). Enrollment information is available here.

The trial’s primary idea is to establish a changes in lung function, totalled by a flat delayed critical ability — a limit volume of atmosphere that can be solemnly inhaled or exhaled when in a flat (lying face upward) position — after 12 weeks of treatment. This is critical since signs of respiratory ineptitude mostly seem when fibbing down.

Additional objectives embody changes in a Revised ALS Functional Rating Scale ALSFRS-R function, a certified instrument for monitoring incapacity course in ALS patients, including respiratory duty and survival.

Levosimendan is a calcium sensitizer and potassium channel opener. It is widely authorized — nonetheless not in a U.S. — underneath a trade name Simdax as an intraveneous medicine for strident worsening of serious ongoing heart failure. The therapy is also means to stimulate fundamental muscles, like those obliged for breathing, to calcium.

In a prior Phase 2 hearing LEVALS (NCT02487407),66 ALS patients were randomized to diagnosis with levosimendan (1 mg and 2 mg daily doses) or remedy for dual weeks distant by a wash-out duration (19-23 days). After completing a third diagnosis period, patients continued to an open-label follow-up partial for 6 months.

Treatment with levosimendan was found to be generally well-tolerated, with many common inauspicious events including headache and an increasing heart rate.

These side effects led to discontinuations, especially due to increasing heart rate, in one studious on a 1 mg sip and 10 receiving 2 mg of levosimendan. The remedy organisation had dual discontinuations.

LEVALS’ primary endpoint was changes in delayed critical ability when sitting during 9 months, though a investigate unsuccessful to strech differences among a groups. However, levosimendan diagnosis led to earnest signals in flat delayed critical capacity.

Results were presented during a 28thInternational Symposium on ALS/MND in Dec 2017 in a print titled,“Oral levosimendan (ODM-109):
Key placebo-controlled formula from a proviso 2 investigate in ALS patients with SVC between 60-90% likely during screening

If a Phase 3 hearing is positive, Orion skeleton to record for selling permission for verbal administration of levosimendan in ALS in a United States and Europe; it has been designated an waif drug in both countries.
