Altimmune Submits Investigational New Drug Application for NasoShield in Preparation for its Phase 1 Trial

Dec 11, 2017

145 Patients to be enrolled
Data expected in the second quarter of 2018
Study will be fully-funded by BARDA

GAITHERSBURG, Md., Dec. 11, 2017 (GLOBE NEWSWIRE) --  Altimmune, Inc. (Nasdaq:ALT), a clinical-stage immunotherapeutics company, today announced the Company has submitted an Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) for NasoShield, the Company’s next generation anthrax vaccine.  In animal models, a single dose of NasoShield induces rapid and durable antibody responses and protects against lethal challenge likely in half the time as the current FDA approved anthrax vaccine, which requires multiple doses.

“We are excited to continue to move the NasoShield program forward with this IND filing and look forward to starting the initial human clinical trial in early 2018,” said Dr. Sybil Tasker, Chief Medical Officer at Altimmune.  “In the setting of a bioterrorism event or natural exposure, a single dose, needle-free vaccine would avoid taxing health care resources and represents a great improvement over current standard of care. We are proud to help the government improve responsiveness to public health threats and look forward to achieving the milestones of this important project.”

This Phase 1 study will assess the safety and immunogenicity of a single intranasal dose of NasoShield at four dose cohort levels. One additional cohort will receive a repeated dose at Day 21.  The study is expected to enroll 145 patients who will receive either NasoShield, three doses of the currently licensed anthrax vaccine, or placebo.  Data on the single dose cohorts are expected sometime in the second quarter of 2018.

The NasoShield program is funded through a contract currently valued at $21.6 million with options, that if fully exercised, has a value of $127 million (HHSO100201600008C) with the Biomedical Advanced Research and Development Authority (BARDA), which runs through September 2021, and, if all options are exercised, will provide funding through the end of Phase 2 development.
