What is the drug thought to do in the body?

Lenzumestrocel (Neuronata-R® inj.) is a collection of stem cells taken from the participant, called ‘mesenchymal stem cells’. These stem cells can develop into many different cell types such as nerves and muscles. Treatment with Lenzumestrocel is expected to target several pathways that can stimulate the growth of new nerve cells and regulate the immune systems response to damaged cells. 

Phase 3 - ALSUMMIT

Current status: Collecting data 

Primary objective: To investigate if Lenzumenstrocel can change the rate of disease progression and survival, using the Joint rank score (combined assessment of function and survival). 

The phase 3 trial is investigating the long-term effects, safety and efficacy of Lenzumestrocel in a placebo-controlled, double-blind trial. The study recruited 115 participants which were split into 3 groups - 2 treatment groups and a placebo group. Both treatment groups will be given 2 injections at 26-day intervals, with the second treatment group being given an additional 3 injections at 3-month intervals. All participants will be given Riluzole as a baseline throughout the study. You can read more about this study here.

The trial recruited in South Korea only.

Previous Clinical Trials

Phase 1 trial

The phase 1 clinical trial tested the safety of Lenzumestrocel by injecting one dose into 8 participants with MND. The study measured changes to the participants vital signs such as breathing ability, heart health and blood tests, showing the treatment was safe. 

Phase 2 trial

The phase 2 trial compared the safety and tolerability of the drug in 37 people living with MND with a control group of people without the disease. Participants received the treatment twice over 2 months and were monitored for 6 months. The treatment was also found to be safe and well-tolerated. Some participants saw a slowing in disease progression 3 months after treatment, as measured by ALSFRS-R.  However, as this was a small trial, further research is needed to gather evidence on whether it is beneficial for people with MND.
