Item 8.01 Results of Operations and Financial Condition.
On August 31, 2022, HilleVax, Inc. (the “Company”) announced that an independent safety data monitoring committee (the “DMC”) completed a prespecified review of safety data from 203 subjects enrolled in the run-in portion of NEST-IN1 (“Norovirus Efficacy and Safety Trial for Infants” or “NOR-212”), the Company’s Phase 2b trial for HIL-214. HIL-214 is the Company’s investigational virus-like particle based vaccine candidate for the prevention of moderate-to-severe norovirus-related acute gastroenteritis in infants. Based on its review, the DMC recommended continuation of NEST-IN1 without modification, and enrollment has subsequently resumed. The Company also announced that it intended to report immunogenicity results from the first 200 subjects in NEST-INI in the fourth quarter of 2022 and remained on-track for topline safety and efficacy data from the full study in the second half of 2023.
NEST-IN1 is a Phase 2b, randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy, safety, and immunogenicity of HIL-214 in infants of approximately 5 months of age at the time of initial vaccination at sites in the United States and Latin America. The study is planned to enroll 3,000 subjects who will be randomized 1:1 to receive a two-dose regimen of either HIL-214 or placebo. The clinical trial protocol includes a prespecified 200 subject run-in to assess safety and immunogenicity. The primary objective of the trial is to evaluate the protective efficacy of HIL-214 against the first confirmed moderate or severe AGE event due to a HIL-214 vaccine strain, GI.1 or GII.4, (excluding certain co-infections) that occurs prior to each subject reaching 12 months of age. A key secondary endpoint is to evaluate the protective efficacy of HIL-214 against any GI or GII norovirus strain.
Forward-Looking Statements
The Company cautions you that statements contained in this current report regarding matters that are not historical facts are forward-looking statements. The forward-looking statements are based on our current beliefs and expectations and include, but are not limited to: the expected continuation of enrollment in the NEST-IN1 trial and the expected timing of data readouts from this trial. Actual results may differ from those set forth in this current report due to the risks and uncertainties inherent in the Company’s business, including, without limitation: the Company currently depends entirely on the success of HIL-214, and the Company has not yet completed any clinical trials of HIL-214; potential delays in the commencement, enrollment, and completion of clinical trials and preclinical studies; the Company’s dependence on third parties in connection with manufacturing, research and clinical and preclinical testing; unexpected adverse side effects or inadequate immunogenicity or efficacy of HIL-214 or any future vaccine candidates that may limit their development, regulatory approval, and/or commercialization; unfavorable results from clinical trials; results from prior clinical trials and studies not necessarily being predictive of future results; the Company’s ability to maintain undisrupted business operations due to the COVID-19 pandemic, including delaying or disrupting the Company’s clinical trials, manufacturing and supply chain; regulatory developments in the United States and foreign countries; any future impacts to the Company’s business resulting from the conflict between Russia and Ukraine or other geopolitical developments outside the Company’s control; and other risks described in the Company’s prior press releases and the Company’s filings with the Securities and Exchange Commission (the “SEC”), including under the heading “Risk Factors” in the Company’s quarterly report on Form 10-Q and any subsequent filings with the SEC. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof, and the Company undertakes no obligation to update such statements to reflect events that occur or circumstances that exist after the date hereof. All forward-looking statements are qualified in their entirety by this cautionary statement, which is made under the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.
