Nasal monoclonal antibody treatment for COVID-19 shows promise for treating virus, other diseases

March 10, 2023
Similar reduction in inflammatory markers were seen when given to patients with multiple sclerosis.

A pilot trial by investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, tested the nasal administration of the drug Foralumab, an anti-CD3 monoclonal antibody.

Investigators found evidence that the drug dampened the inflammatory T cell response and decreased lung inflammation in patients with COVID-19. Further analysis showed the same gene expression modulation in patients with multiple sclerosis, who experienced decreased brain inflammation, suggesting that Foralumab could be used to treat other diseases. Their results are published in the Proceedings of the National Academy of Sciences.

In both COVID-19 and multiple sclerosis, the immune system is overactive. Foralumab, manufactured by Tiziana Life Sciences, is a drug that stimulates regulatory T cells of the immune system, or anti-inflammatory cells, resulting in decreased inflammation. This contrasts with other monoclonal antibodies previously given to treat or prevent symptoms of COVID-19 (such as Evusheld) that target the SARS-CoV-2 spike protein, which only had activity against specific variants and subvariants.
