Blue Water Vaccines Announces Exclusive, Global License Agreement for Chlamydia Vaccine Candidate Development from The University of Texas Health San Antonio

CINCINNATI, Nov. 21, 2022 (GLOBE NEWSWIRE) — Blue Water Vaccines Inc. (“BWV” or “Blue Water Vaccines” or “the Company”) a biopharmaceutical company developing transformational vaccines to address significant global health challenges, today announced the signing of an exclusive, global license agreement for the development of a live attenuated, oral Chlamydia vaccine candidate from The University of Texas Health San Antonio (“UT Health San Antonio”).

“With millions of new and existing infections each year and no preventative treatment available, there remains a large unmet need for an efficacious Chlamydia vaccine both here in the U.S. and on a global scale,” said Joseph Hernandez, Chairman and Chief Executive Officer of Blue Water Vaccines. “We are thrilled to enter into this partnership with UT Health San Antonio and to pursue development of this groundbreaking vaccine candidate.”

Developed in the laboratory of Guangming Zhong, Ph.D., at UT Health San Antonio, the novel vaccine candidate utilizes a live attenuated Chlamydia strain, Chlamydia muridarum (“C. muridarum”). After oral delivery of the vaccine, C. muridarum was able to colonize in the gastrointestinal tract of mice and induce transmucosal protection against genital tract Chlamydia infection, without altering the gut microbiota or the development of gut mucosal resident memory T cell responses to a non-chlamydial infection. In addition, the vaccine was shown to be nonpathogenic in mice, indicating the potential to develop the live attenuated C. muridarum vaccine into a protective, human Chlamydia vaccine.

“Chlamydia vaccines have historically been challenging to produce, but our novel approach has demonstrated strong results in mouse models, which we believe will translate into a human vaccine candidate,” said Dr. Zhong of UT Health San Antonio. “We look forward to this new partnership with Blue Water Vaccines and to the development of this vaccine to benefit patients worldwide.”

According to the CDC, Chlamydia is the most frequently reported bacterial STI in the United States, with about 1.6 million new cases reported in 2020 alone. Globally, the WHO estimates about 129 million new cases of chlamydia each year and may be and underrepresentation given many cases are asymptomatic and low availability of diagnostic testing in low- and middle-income countries. Currently, there is no vaccine available to prevent chlamydia infection, and the main treatment is through antibiotic regimens with the possibility of reinfection after antibiotics have treated the disease. If undetected or left untreated, Chlamydia represents a major cause of pelvic inflammatory disease and infertility in women.
