Sovateltide Mediated Endothelin B Receptors Agonism and Curbing Neurological Disorders

International Journal of Molecular Sciences, 2022 · DOI: 10.3390/ijms23063146 · Published: March 15, 2022

Simple Explanation

This review discusses neurological disorders such as stroke and Alzheimer's disease, highlighting the complex challenges in developing effective treatments. It focuses on the endothelin system and the potential of endothelin B receptors (ETBRs) as drug targets. The review emphasizes the drug sovateltide (IRL-1620), a selective agonist of ETBRs, and its potential in treating neurological disorders. It presents preclinical and clinical data demonstrating sovateltide's safety and efficacy in treating acute ischemic stroke and ongoing studies for Alzheimer's disease and spinal cord injury. Ultimately, the paper suggests that ETBRs signaling could be a key target for developing new drugs to treat a range of neurological and neurovascular diseases, holding promise for future therapeutic interventions.

Study Duration

Not specified

Participants

Healthy male volunteers and cerebral ischemic stroke patients

Evidence Level

Level II; Clinical Phase I and Phase II trials, Preclinical animal studies

Key Findings

1
Sovateltide has shown promise in preclinical studies for treating cerebral stroke, Alzheimer's disease, spinal cord injury, and neonatal hypoxic-ischemic encephalopathy by promoting neuroprotection and neuroregeneration.
2
Clinical phase I studies have demonstrated sovateltide to be safe and tolerable at therapeutic dosages, while phase II studies have indicated its efficacy in treating acute ischemic stroke.
3
Sovateltide uniquely promotes the differentiation of neuronal progenitor cells into mature neuronal cells, suggesting a novel mechanism of action for treating CNS disorders.

Research Summary

This review highlights the potential of sovateltide, a selective ETBRs agonist, as a therapeutic candidate for neurological disorders. Preclinical and clinical studies suggest its safety and efficacy in treating acute ischemic stroke, with ongoing trials for Alzheimer’s disease and spinal cord injury. Sovateltide promotes neuroprotection, neuroregeneration, and the differentiation of neuronal progenitor cells, offering a unique approach to treating CNS disorders. The findings provide hope for developing effective therapies for previously non-curable neurological diseases, pending the results of ongoing clinical trials.

Practical Implications

Drug Development

ETBRs agonism, particularly through sovateltide, presents a novel target for developing first-in-class drugs for stroke, Alzheimer's disease, spinal cord injury, and neonatal hypoxic-ischemic encephalopathy.

Clinical Treatment

Sovateltide could become an adjuvant therapy to existing treatments, enhancing neuroprotection and regeneration in patients with neurological disorders.

Future Research

Further studies are warranted to fully elucidate the mechanisms of action of sovateltide and to explore its potential in treating other neurological conditions.

Study Limitations

1
The review primarily focuses on the endothelin system and sovateltide, potentially overlooking other therapeutic targets and approaches.
2
Clinical trial data for Alzheimer's disease and spinal cord injury are still ongoing, limiting definitive conclusions about sovateltide's efficacy for these conditions.
3
The complex pathophysiology of neurological disorders may require combinatorial therapies, which are not extensively addressed in this review.
