ILiAD Biotechnologies Announces $42.8M Financing Round to Advance BPZE1 Pertussis Vaccine

The announced financing is led by Knott Partners. With the addition of the Class D financing, over $100 million in cumulative funding has now been secured for the development of BPZE1.

BPZE1 is the most advanced next generation pertussis vaccine, designed to overcome deficiencies of current vaccines, including limited durability and the inability to prevent nasopharyngeal Bordetella pertussis infections that lead to transmission, especially to vulnerable infants. BPZE1 has successfully completed four human clinical studies and at the end of 2021, the FDA provided BPZE1 with Fast Track designation.

In addition to funding continued operations, R&D and manufacturing development of BPZE1, the financing will support further clinical studies of the vaccine. The Phase 2b pertussis Human Challenge clinical study is currently enrolling volunteers and will directly measure whether ILiAD’s candidate vaccine, BPZE1, can prevent nasopharyngeal B. pertussis colonization after direct challenge with wild-type B. pertussis bacteria. In preclinical studies, BPZE1 was able to prevent B. pertussis colonization after wild-type B. pertussis challenge, while acellular pertussis vaccines were not.

“We are very pleased to close the $42.8M Class D investment which will allow ILiAD to continue to progress the development of our leading next generation pertussis vaccine,” said Keith Rubin, MD, Founder and Chief Executive Officer of ILiAD. Dr. Rubin added, “From day one, the importance of inducing mucosal immunity has been central to ILiAD’s mission to achieve global eradication of disease due to B. pertussis and it’s gratifying that key investors, public health agencies and leaders in the field of infectious disease are recognizing its pivotal role.”

BPZE1 was developed by Camille Locht, PhD and Nathalie Mielcarek, PhD at the Institut Pasteur de Lille (https://pasteur-lille.fr/en/) and French National Institute of Health and Medical Research (https://www.inserm.fr/en). ILiAD holds exclusive global rights to BPZE1 and related B-Tech™ technologies that are covered by 62 issued patents. An additional 31 patents are pending globally.

About Pertussis

Pertussis (whooping cough) is a life-threatening disease caused by the highly contagious respiratory bacterium Bordetella pertussis. According to U.S. Centers for Disease Control and Prevention, each year pertussis affects approximately 16 million people globally, accounting for nearly 200,000 deaths. Although estimated global vaccination coverage is 84%, current vaccines have failed to control epidemics. In addition, current vaccines do not fully protect infants under age 6 months, since immunization requires multiple injections, usually at 2, 4 and 6 months.

About BPZE1

BPZE1 is a next-generation live-attenuated pertussis vaccine designed to induce comprehensive and durable protection against B. pertussis infection (colonization) and disease (whooping cough). BPZE1 is being developed to block B. pertussis from colonizing the upper respiratory tract, protecting adults and adolescents, and potentially preventing transmission especially to infants. While ILiAD is currently focused on developing a vaccine to directly protect adults and adolescents and to indirectly protect vulnerable infants, future development aims to immunize neonates directly.
