In short
Lenzumestrocel, an innovative cell therapy, is currently being studied in clinical trials for its potential to treat knee cartilage defects. This advanced therapy medical product, also known as BiCure ortho MSCp, uses autologous bone marrow-derived mesenchymal stem cells to potentially repair damaged cartilage in the knee joint. The ongoing research aims to evaluate the efficacy and safety of this treatment compared to conventional methods.

What is LENZUMESTROCEL?
LENZUMESTROCEL is an advanced medical treatment that uses autologous bone marrow-derived mesenchymal stem cells. "Autologous" means the cells come from your own body, specifically from your bone marrow. These cells are then expanded (increased in number) in a laboratory and used to treat certain medical conditions.
This treatment is also known by several other names, including:
- NEURONATA-R
- Human culture expanded autologous mesenchymal stromal cells
- Autologous bone marrow derived mesenchymal stem cells, expanded
Medical Conditions Treated
LENZUMESTROCEL is being studied for the treatment of knee cartilage defects. This condition is also referred to as:
- Articular cartilage defect
- Cartilage damage
- Cartilage repair
These terms all refer to damage or wear in the cartilage that covers the ends of the bones in your knee joint. This cartilage helps your knee move smoothly and cushions the bones. When it's damaged, it can cause pain and difficulty moving.
How LENZUMESTROCEL Works
LENZUMESTROCEL is a type of cell therapy. The treatment involves taking your own stem cells, growing more of them in a lab, and then placing them back into your body where they're needed. In this case, the cells are placed onto a 3D scaffold (a structure that supports cell growth) and then applied to the damaged area in your knee.
The stem cells are believed to help repair the damaged cartilage by:
- Developing into new cartilage cells
- Promoting healing in the surrounding tissue
- Reducing inflammation
Clinical Trial Details
LENZUMESTROCEL is currently being studied in a Phase IIb clinical trial. This means it has already shown promise in earlier studies, and researchers are now testing it in a larger group of people to better understand its effectiveness and safety.
The main goal of this trial is to compare two treatments:
- Conventional microfracture (a surgical technique to repair cartilage) plus a 3D scaffold with LENZUMESTROCEL
- Conventional microfracture plus a 3D scaffold alone
Researchers want to see if adding LENZUMESTROCEL to the standard treatment leads to better results for patients with knee cartilage defects.
Eligibility Criteria
To participate in this study, patients must meet certain criteria. Some key requirements include:
- Age between 18 and 55 years
- Diagnosed with chondral defects (cartilage damage) in the weight-bearing part of the knee joint
- The defect is located in the weight-bearing part of the femoral condyle (the end of the thigh bone that forms part of the knee joint)
- The cartilage defect is no larger than 6 cm²
- No previous knee surgery for treating a cartilage defect
There are also several conditions that would prevent someone from participating in the study, such as certain infections, cancer, or pregnancy.
Treatment Procedure
The treatment involves several steps:
- Bone marrow is collected from the patient
- Stem cells are isolated and grown in a laboratory
- The patient undergoes knee surgery (microfracture)
- The expanded stem cells are placed on a 3D scaffold
- The scaffold with stem cells is applied to the damaged area in the knee
The maximum dose of LENZUMESTROCEL used in the study is 5,500,000 cells, given as a single treatment.
Expected Outcomes
The researchers will measure the success of the treatment in several ways:
- Lysholm knee function score: This measures how well your knee functions in daily activities
- KOOS (Knee Injury and Osteoarthritis Outcome Score): This assesses pain, symptoms, daily function, sports activities, and quality of life related to your knee
- Pain levels using a VAS (Visual Analog Scale)
- X-ray and MRI evaluations of the knee
These measurements will be taken at various points over two years to track progress and compare the results between the two treatment groups.
Safety Considerations
While LENZUMESTROCEL has shown promising results in earlier studies, this trial will continue to monitor its safety. Patients will be checked for any adverse events (side effects or complications) throughout the study period.
It's important to note that this is still an experimental treatment. If you're considering participating in this or any clinical trial, always discuss it thoroughly with your doctor to understand the potential risks and benefits.
