Safety results pave way to next stage trials for new drug for common form of motor neurone disease

Recently published study shows acceptable safety and tolerability for the drug of interest in patients affected by Amyotrophic Lateral Sclerosis.

Researchers from the University of Birmingham and Swedish drug development company TikoMed AB have recently published peer reviewed research in PLOS ONE providing additional support that their low molecular weight dextran sulfate compound ILB® is safe and well tolerated in patients with Amyotrophic Lateral Sclerosis (ALS), the most common form of motor neurone disease.

Eleven patients participated in the prospective, single-arm, open-label, phase II clinical trial encompassing long-term weekly ILB® injections for up to 38 weeks of 2 mg/kg.

The trial was carried out at the University Hospitals Birmingham NHS Foundation Trust, by the University of Birmingham’s Drugs, Devices, Diagnostics and Biomarkers (D3B) team from the Cancer Research (UK) Clinical Trials Unit, in collaboration with the pharmaceutical company Tikomed AB who are based in Sweden.

The trial outcomes demonstrated that:

  • Long-term weekly ILB® injections of 2 mg/kg were well tolerated, had minimal side-effects and had an acceptable safety profile in all the 11 patients
  • ALSFRS-R score* and ALSAQ-40 score** changed minimally over the 48-week reporting period which may indicate a slowing of disease progression in this small ILB® treated patient cohort.

TikoMed is now moving forward with planning a phase IIb multi-centre efficacy trial of ILB®.

We worked together to test the safety and tolerability of a new drug called ILB® in patients affected by motor neurone disease, often referred to as Lou Gehrig's disease. We showed that weekly injection of ILB® was safe for patients. We initially planned to deliver 10 weeks of treatment to each patient but were able to safely extend treatment up to 38 weeks. The study had to stop due to the Covid pandemic. Now we know that ILB® treatment is safe we can conduct larger studies to find out if this drug slows progression of motor neurone disease.

This trial demonstrated the good safety profile of long-term weekly injected ILB® in patients with ALS. I am very grateful for the engaging participation by the patients in especially difficult circumstances due to the onset of the pandemic during the trial period.
