HilleVax Reports Second Quarter 2023 Financial Results and Highlights Recent Company Progress

BOSTON, August 14, 2023 – HilleVax, Inc. (Nasdaq: HLVX), a clinical-stage biopharmaceutical company focused on developing and commercializing novel vaccines, today reported financial results for the quarter ended June 30, 2023, highlighted recent progress and outlined key upcoming milestones for HIL-214, the company’s investigational virus-like particle (VLP) based vaccine for the prevention of moderate-to-severe norovirus-related acute gastroenteritis.

“HilleVax has continued to make excellent progress in our HIL-214 program following completion of enrollment of our NEST-IN1 clinical trial in late April 2023. Due to issues relating solely to the logistical complexity of processing diarrheal samples from various geographies, we are adjusting our guidance to read out top line clinical data on all subjects in our NEST-IN1 clinical trial to mid-2024,” said Rob Hershberg, MD, PhD, Chairman and Chief Executive Officer of HilleVax. “We remain committed to potentially bringing the first vaccine to market to address the global unmet need associated with norovirus infections.”

Recent Business Highlights

In Q2 2023, HilleVax announced completion of enrollment of the NEST-IN1 (Norovirus Efficacy and Safety Trial for INfants) Phase 2b clinical trial with over 3,000 subjects enrolled in six countries.
In Q2 2023, HilleVax announced the appointment of Nanette Cocero, Ph.D., MBA, to its Board of Directors.

Upcoming Expected Milestones

Topline safety and clinical efficacy data from NEST-IN1 in mid-2024.

Second Quarter 2023 Financial Results

As of June 30, 2023, the company had cash, cash equivalents and marketable securities totaling $244.1 million.

Research and development expenses for the second quarter 2023 were $23.0 million, compared to $8.8 million for the second quarter 2022. The increase was primarily due to increased activities for the development of HIL-214 and the growth in the number of R&D employees.

General and administrative expenses for the second quarter 2023 were $7.2 million, compared to $4.0 million for the second quarter 2022. The increase was primarily due to the growth in the number of G&A employees.

Other income for the second quarter 2023 was $2.3 million, compared to $41.1 million of other expense for the second quarter 2022. The other income in the second quarter of 2023 was primarily driven by interest income on the company’s cash, cash equivalents and marketable securities, while the other expense in the second quarter of 2022 was primarily driven by changes in the fair value of convertible promissory notes and warrant liabilities.

Net loss for the second quarter 2023 was $27.9 million, compared to $53.9 million for the second quarter 2022.



About HilleVax
