Breakthrough Treg Therapy Offers New Hope for ALS Patients
Breakthrough in ALS Treatment with Treg Cell Therapy
Recently, significant advancements have emerged in the treatment of Amyotrophic Lateral Sclerosis (ALS), a challenging neurodegenerative disease. Cellenkos Inc. has pioneered an innovative cryopreserved allogeneic T regulatory (Treg) cell therapy, showing promising results including clinical safety and preliminary efficacy for ALS patients.
Clinical Findings and Treatment Approach
Research indicates that the administered Treg infusion significantly slows down disease progression and leads to improved biomarkers. The study highlights that patients receiving this novel therapy exhibited a slowed decline in their ALS Functional Rating Scale-Revised (ALSFRS-R) scores. Prior to the treatment, the scores decreased at an alarming average rate of ?1.66 points per month. During the treatment phase, this decline dramatically slowed to only ?0.41 points per month.
Notably, following the completion of therapy, the decline rate slightly increased to ?0.60 points per month, signaling a continued benefit from the treatment. Alongside the clinical improvements, reductions in plasma neurofilament levels—a critical biomarker for neuronal injury—were also observed, further supporting the treatment's effectiveness.
Treatment Protocol and Patient Experience
Patients received treatment in an outpatient setting through intravenous infusions, with each participant administered a standard fixed dose of 100 million Treg cells. The regimen began with weekly infusions for the first month, transitioning to monthly doses over six months, with potential for additional infusions depending on the needs and discretion of their physician. Importantly, this treatment protocol does not necessitate lymphodepletion, immunosuppression, or HLA matching, allowing for same-day discharge from the outpatient facility. Furthermore, the absence of dose-limiting toxicities is a notable achievement in this study.
The pivotal trial involved six participants, averaging a median age of 48.5 years, who received a median of 11 infusions during the follow-up period, during which all participants remained alive. Among those with adequate follow-up data, the median duration of follow-up was 18 months, providing encouraging feedback on the therapy's longevity and efficacy.
Innovations from Cellenkos and Future Directions
Dr. Simrit Parmar, the founder of Cellenkos and a faculty member at Texas A&M University, expressed that these results signal a transformative moment for individuals facing ALS. Unlike traditional cell therapies that are often costly and intricate, Cellenkos's Treg therapy is off-the-shelf and ready for use, significantly simplifying the treatment process.
Looking ahead, Cellenkos is progressing with their next-generation product, CK0803, which is designed to enhance the therapy's effectiveness by overexpressing specific proteins that help Tregs migrate to inflammatory sites in the brain. This could potentially improve targeting of ALS-related pathologies, further aligning these new therapies with the needs of patients.
Understanding Amyotrophic Lateral Sclerosis (ALS)
ALS is a relentless neurodegenerative disease that impacts the nerve cells responsible for voluntary muscle movements. As the disease progresses, individuals experience increasing muscle weakness and paralysis, leading to severe limitations in daily activities. Tragically, most patients diagnosed with ALS do not survive beyond a few years. Presently, there is no cure available, putting intense emphasis on the urgency for new treatments.

Utilizing their proprietary platform, CRANE, Cellenkos's therapies can be tailored without the need for HLA or ABO matching. The innovative approach allows for outpatient administration and enhances rapid, point-of-care delivery of treatments, benefiting patients and healthcare providers alike.
Frequently Asked Questions
What are Treg cells and how do they work in ALS treatment?
Treg cells are specialized immune cells that help to regulate and maintain immune responses. In ALS treatment, they may help slow disease progression by reducing inflammation and protecting neuronal cells.
How effective is Cellenkos' Treg therapy?
Clinical studies show that this therapy significantly slows disease progression and reduces markers of neuronal injury, indicating a positive impact on ALS symptoms.
What is the treatment process for patients receiving Treg therapy?
Patients receive a series of intravenous infusions of Treg cells. The initial treatment consists of weekly infusions that transition to monthly doses for an extended period.
Are there any side effects reported with Treg therapy?
In the clinical trial, no dose-limiting toxicities were reported, suggesting that Treg therapy is safe and well-tolerated by patients.
What future developments can we expect from Cellenkos?
Cellenkos is advancing next-generation therapies, including CK0803, aimed at improving the targeting of therapies to inflamed brain regions and further enhancing treatment efficacy in ALS.
