CAPE CANAVERAL, Fla., March 27, 2024 (GLOBE NEWSWIRE) -- Vaxxinity, Inc. (Nasdaq: VAXX), a U.S. company pioneering the development of a new class of immunotherapeutic vaccines, today reported financial results for the fourth quarter and full year ended December 31, 2023, and provided a corporate update.

“2024 will prove to be a critical year for Vaxxinity as we refocus our efforts on our neurodegeneration programs and move closer to obtaining our company’s first approval,” said Mei Mei Hu, CEO of Vaxxinity. “Just this month, we presented exploratory biomarker data from our Phase 1 trial of UB-312 in Parkinson’s patients: a first of its kind demonstrating target engagement of toxic alpha-synuclein in the CNS and a potential correlation with clinical efficacy. This represents a major step for our platform in neurodegeneration where the safe engagement of aberrant protein targets in the CNS remains critical, and new hope for the Parkinson’s community. We also seek to advance UB-311, our anti-Aβ Alzheimer’s candidate, as we resume dialogue with regulatory authorities and partners. Finally, we’re looking forward to the readout from the Phase 1 trial of VXX-401, our vaccine candidate for hypercholesterolemia, as well as the potential marketing authorization of UB-612, our heterologous booster vaccine candidate for COVID-19.”

2023 and Recent Clinical Pipeline Developments

UB-312 in Parkinson’s disease (PD) and other synucleinopathies

• UB-312 targets toxic forms of aggregated α-synuclein (aSyn).
• Two exploratory CSF biomarkers show promise as measures of disease progression:
  • aggregated aSyn, as measured by an aSyn Seed Amplification Assay developed in collaboration with Mayo Clinic, UTHealth Houston, and Amprion, with funding from The Michael J. Fox Foundation.
  • phosphorylated aSyn (pS129-aSyn).
• PD patients with UB-312-induced antibodies in CSF had significantly less aSyn aggregation (p = 0.0183) and pS129-aSyn (p = 0.0351) as compared to placebo.
• PD patients with UB-312-induced antibodies in CSF showed significant improvement in the clinical MDS-UPDRS II activities of daily living scale as compared to placebo (p = 0.0062).
• Anti-aSyn antibody titer levels in CSF correlate with reduction in aggregated aSyn, which correlated with improvement in MDS-UPDRS II.
• In March 2024, JC Dodart, Chief Scientific Officer, presented these exploratory analyses at AD/PD 2024 in Lisbon, Portugal.

VXX-401 in hypercholesterolemia

• VXX-401 targets proprotein convertase subtilisin/kexin type 9 (PCSK9) to reduce LDL cholesterol.
• All six cohorts of the Phase 1 trial of VXX-401 are fully enrolled.
• In February 2024, results from multiple preclinical studies of VXX-401 in non-human primates, demonstrating robust, sustained reduction in LDL-C, were published in the Journal of Lipid Research.
• The company anticipates topline Phase 1 data by mid-2024.

UB-612 COVID-19 booster

• UB-612 employs a “multitope” approach to neutralizing the ancestral SARS-CoV-2 virus and its variants.
• In November 2023, Vaxxinity presented data from its head-to-head Phase 3 trial of UB-612 at Vaccines Summit in Boston, MA, and published a peer-reviewed article about UB-612 in Vaccine reporting antibody response against SARS-CoV-2 in cynomolgus macaques.

2023 and Recent Corporate Updates

• Academic Collaborations & State of Florida Grant. In January 2024 Vaxxinity announced a collaboration with the University of Central Florida to conduct research funded by the state of Florida to further the development of our active immunotherapies against myostatin and activin A to prevent and mitigate muscle and bone wasting, well-known health challenges related to long-term spaceflight. These targets share biological mechanisms implicated in obesity, diabetes, and highly prevalent age-related diseases. In the same month, Vaxxinity announced a collaboration with the University of Florida’s Center for Translational Research in Neurodegenerative Disease (CTRND) to support our development of vaccines for neurodegenerative diseases.

Fourth Quarter and Year End 2023 Financial Results

As of December 31, 2023, Vaxxinity had $30.4 million of highly liquid assets, including $4.9 million of cash and cash equivalents and $25.5 million of short-term investments, compared to $86.8 million as of December 31, 2022.

Comparison of three months ended December 31, 2023 to three months ended December 31, 2022

Research and development expenses were $8.2 million and $13.1 million for the three months ended December 31, 2023 and 2022, respectively.

The $4.9 million decrease in research and development expenses was primarily due to decreases in program-related costs of $0.6 million for our UB-313 migraine program, $0.4 million for our VXX-401 hypercholesterolemia program, and $0.4 million for our UB-312 Parkinsons program, as well decreases in personnel and consulting costs totaling $2.1 million.

General and administrative expenses were $3.4 million and $7.7 million for the three months ended December 31, 2023, and 2022, respectively.

The $4.3 million decrease was primarily due to a decrease in personnel costs of $1.7 million, consulting and professional services totaling $0.9 million, and travel expenses of $0.5 million.

Net loss for the three months ended December 31, 2023, was $11.4 million or $0.09 per share compared to $20.5 million or $0.16 per share for the three months ended December 31, 2022.

Comparison of the year ended December 31, 2023 to the year ended December 31, 2022

Research and development expenses were $35.9 million and $47.6 million for the years ended December 31, 2023 and 2022, respectively.

The $11.7 million decrease in research and development expenses was primarily due to decreases in program-related costs of $4.3 million for our UB-612 Covid-19 program and $1.0 million for our UB-312 Parkinson’s Disease program, as well decreases in personnel costs of $4.2 million and consulting costs of $1.8 million.

General and administrative expenses were $22.4 million and $28.4 million for the years ended December 31, 2023, and 2022, respectively.

The $6.0 million decrease was primarily due to a decrease in personnel costs of $2.0 million, D&O insurance premiums of $1.8 million, and consulting and professional services costs of $1.2 million.

Net loss for the year ended December 31, 2023, was $56.9 million or $0.45 per share compared to $75.2 million or $0.60 per share for the year ended December 31, 2022.
