Pfizer (PFE) Streptococcus Jab Gets FDA's Breakthrough Tag

In this article:

Pfizer PFE announced that the FDA has granted Breakthrough Therapy Designation to its Group B Streptococcus (GBS) vaccine candidate.

The prestigious designation to the vaccine candidate, GBS6 or PF-06760805 has been given for the prevention of invasive GBS infections due to vaccine serotypes in newborns and young infants by active immunization of their mothers during pregnancy. GBS6 is being evaluated in the phase II study in healthy pregnant women aged 18 to 40 years in South Africa, the United Kingdom, and the United States. Interim data from this study formed the basis for the BTD tag.

The FDA’s BTD designation facilitates the development and expedites the review of new drugs and vaccines intended to treat or prevent serious conditions and address unmet medical needs.

Pfizer’s stock is down 21.9% this year so far compared with a decrease of 4.3% for the industry.

GBS is a common bacterium, which is usually harmless in healthy adults. However, in newborns it can cause serious illnesses like meningitis, pneumonia, and sepsis. At present, prenatal screening and antibiotics during childbirth are mediums used to protect against GBS. However, these are not fully effective in preventing GBS disease, especially beyond the first week of life. If approved for use in pregnant women, the GBS6 vaccine can help prevent GBS disease in newborns.

GBS6 was granted PRIME designation by the European Medicines Agency’s Committee for Medicinal Products for Human Use in April.
