Guillain-Barré Syndrome (GBS): Understanding

Guillain-Barré Syndrome (GBS): Overview

Guillain-Barré Syndrome (GBS) is a rare neurological disorder in which the immune system mistakenly attacks part of the peripheral nervous system, the network of nerves located outside of the brain and spinal cord. GBS can range from a very mild case with brief weakness to nearly devastating paralysis, leaving you unable to breathe independently. Fortunately, most people eventually recover from even the most severe cases of GBS. After recovery, some people will continue to have some degree of weakness. GBS can increase in intensity over a period of hours, days, or weeks until certain muscles cannot be used at all and, when severe, the person is almost totally paralyzed. In these cases, the disorder is life-threatening, potentially interfering with breathing and, at times, with blood pressure or heart rate..

Two characteristic symptoms of GBS are Weakness and Sensory Changes. Weakness is usually symmetrical and worsens within hours or days, with most individuals reaching their peak weakness within two weeks. Sensory changes, such as tingling, pain, or the sensation of insects crawling under the skin, are common, particularly in the feet or hands. Other symptoms can include difficulty with eye muscles, swallowing, speaking, and chewing, along with coordination problems, severe pain (especially at night), and autonomic issues like abnormal heart rate, blood pressure, and digestion.

Antecedent infections, particularly with Campylobacter jejuni, are found in up to 70% of Guillain-Barré Syndrome (GBS) cases, with molecular mimicry playing a key role in the disease’s development. The lipooligosaccharide of Campylobacter jejuni shares similarities with gangliosides on peripheral nerve membranes, triggering immune responses that damage the nerves. Specific antibodies, such as anti-GD1a, anti-GM1, and anti-GQ1B, target different components of peripheral nerves, influencing the clinical presentation of GBS. For instance, Miller-Fisher syndrome is linked to anti-GQ1B antibodies, while axonal motor neuropathy is associated with anti-GM1 antibodies. However, not all GBS patients test positive for these antibodies, suggesting the need for further research to better understand their role and the pathophysiology of GBS.

The diagnosis of Guillain-Barré Syndrome (GBS) relies on clinical history, examination, and supportive tests like cerebrospinal fluid (CSF) analysis and electrodiagnostic studies, as there are no specific biomarkers. The two main diagnostic criteria are the NINDS criteria (1978), which is more clinically focused and includes typical and atypical GBS features, and the Brighton Collaboration criteria (2011), which helps classify GBS or Miller-Fisher Syndrome (MFS) based on diagnostic certainty. Differential diagnoses must be considered, as GBS shares symptoms with several other disorders, making early diagnosis challenging. There is no cure for Guillain-Barré Syndrome (GBS), but treatments like plasma exchange (plasmapheresis) and intravenous immunoglobulin (IVIg) can help reduce immune-related nerve damage and shorten recovery time if started early. Hospital care focuses on preventing complications, such as respiratory support, pain management, and physical therapy. Rehabilitation helps regain strength and independence. While most people recover fully, some may experience residual weakness, fatigue, and long-term complications, requiring ongoing care and psychological support.

Guillain-Barré Syndrome (GBS) Emerging Drugs Chapters

This segment of the Guillain-Barré Syndrome (GBS) report encloses its detailed analysis of various drugs in different stages of clinical development, including Phase III, II, I, Preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Guillain-Barré Syndrome (GBS) Emerging Drugs

ANX005: Annexon, Inc.

ANX005, is a first-of-its kind selective, targeted and rapid-acting agent designed to reduce inflammation and nerve damage by stopping C1q activity in the peripheral and central nervous systems. In GBS, ANX005 is designed to seek out C1q and prevent its binding to targets on peripheral nerves. ANX005 is administered intravenously and has been observed to act almost immediately in blocking C1q function. The aim of an effective treatment in GBS is to rapidly stop the autoimmune damage on nerve cells, allowing patients to regain muscle strength sooner and to regain independence and return to pre-illness activities. ANX005 has received both Fast Track and Orphan Drug designations from the U.S. Food and Drug Administration as well as orphan drug designation from the European Medicines Agency for the treatment of GBS. Currently the drug is in Phase III stage of Clinical trial evaluation for the treatment of Guillain-Barré Syndrome (GBS).

Imlifidase: Hansa Biopharma

Imlifidase is a unique antibody-cleaving enzyme originating from Streptococcus pyogenes that specifically targets IgG and inhibits IgG-mediated immune response. It has a rapid onset of action, cleaving IgG-antibodies and inhibiting their activity within hours after administration. imlifidase can effectively and very rapidly remove immunoglobulin G through enzymatic cleavage – halting the progression of nerve damage associated with GBS and stopping disease progression. By rapidly reducing harmful IgG antibodies, imlifidase could potentially halt the progression of GBS, leading to quicker recovery and improved functional outcomes for patients. The U.S. Food and Drug Administration has also granted Orphan Drug Designation to imlifidase for the treatment of GBS Currently, the drug is in Phase II stage of its development for the treatment of Guillain-Barré Syndrome (GBS).
