Vaxxinity Reports Third Quarter 2023 Financial Results and Provides Corporate Update

CAPE CANAVERAL, Fla., Nov. 08, 2023 (GLOBE NEWSWIRE) — Vaxxinity, Inc. (Nasdaq: VAXX), a U.S. company pioneering the development of a new class of medicines, today reported financial results for the third quarter ended September 30, 2023, and provided a corporate update.

“We continue to advance our clinical programs and to validate our platform with the goal of addressing major chronic diseases with more convenient, cost-effective, and accessible immunotherapies worldwide. This quarter, we have demonstrated proof of technology with our third clinical program, as well as our first proof of mechanism in our UB-312 program for Parkinson’s. We have observed clear target engagement with aggregated alpha-synuclein in patient CSF, indicating that UB-312-induced antibodies cross the blood-brain barrier and engage the toxic pathology of Parkinson’s disease,” said Mei Mei Hu, CEO of Vaxxinity. “Our expertise in developing active immunotherapies that break immune tolerance and generate specific, potent antibodies against self-antigens has us well positioned to achieve our next important milestones in the coming year: in addition to further analyses of data from our UB-312 trial, we are excited for initial topline results from our Phase 1 trial of VXX-401, which targets PCSK9 for hypercholesterolemia, expected in the first half of 2024, and our first potential approval with UB-612 as a COVID-19 booster in the UK and Australia.

“Furthermore, we are excited to add two industry veterans to our executive leadership team: Peter Powchik, M.D., as Executive Vice President, Global Scientific Director, and Sumita Ray, J.D. as Chief Legal, Compliance, and Administrative Officer. With over 10 approved drugs and 50 years of life sciences experience combined, these additions elevate our talented team and strengthen our abilities to execute going forward. Finally, with the conclusion of several clinical trials, we’ve found efficiencies to reduce our cash burn and extend our runway.”

Third Quarter 2023 and Recent Updates

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

• UB-312 targets toxic forms of aggregated alpha-synuclein (aSyn) in the brain.
• In the Phase 1 trial, UB-312 successfully broke immune tolerance in 12 out of 13 Parkinson’s patients who completed dosing.
• UB-312-induced antibodies slowed aSyn aggregation in patient cerebrospinal fluid (CSF), demonstrating BBB crossing and target engagement in vivo.
• UB-312 reduced aggregated aSyn in PD patients over time, as compared to placebo, as measured by fluorescence max in a seed amplification assay.
• This data has been generated through a two-year partnership funded by The Michael J. Fox Foundation (MJFF) to explore quantitative markers of target engagement, with a focus on aggregated aSyn in biological fluids.

UB-311 in Alzheimer’s disease (AD)

• UB-311 targets toxic forms of aggregated amyloid-β in the brain to fight Alzheimer’s disease (AD).
• Results from the Phase 2a trial of UB-311 in patients with mild AD were published in The Lancet’s eBioMedicine in August 2023.
• The U.S. Food and Drug Administration has granted Fast Track Designation for UB-311 for the treatment of AD.

VXX-401 in hypercholesterolemia

• VXX-401 targets proprotein convertase subtilisin/kexin type 9 (PCSK9) to reduce low-density lipoprotein (LDL) cholesterol.
• The first four cohorts of the Phase 1 trial of VXX-401 are fully enrolled, and as of October 2023, we have expanded the trial to test higher dose levels of VXX-401 due to its favorable safety and tolerability profile to date.
• The company is on track to report initial topline data from the trial in the first half of 2024.

UB-612 COVID-19 booster

• UB-612 employs a peptide-protein subunit approach to neutralizing the ancestral SARS-CoV-2 virus and its variants.
• Regulatory authorities in the UK and Australia are reviewing Vaxxinity’s application for conditional/provisional marketing authorization of UB-612 under their established work share agreement. If successful, this submission lays the groundwork for regulatory filings and the commercialization of UB-612 in other countries, including low- and middle-income countries.

Third Quarter 2023 Financial Results

As of September 30, 2023, Vaxxinity had $42.5 million of highly liquid assets, including $17.4 million of cash and cash equivalents and $25.1 million of short-term investments, compared to $86.8 million as of December 31, 2022.

Comparison of three months ended September 30, 2023 to three months ended September 30, 2022

Research and development expenses were $7.9 million and $12.5 million for the three months ended September 30, 2023 and 2022, respectively.

The $4.6 million decrease in research and development expenses was primarily due to decreases in costs related to our UB-612 COVID-19 vaccine program totaling $2.4 million and decreases in personnel and consulting costs totaling $2.3 million, partially offset by increases in our VXX-401 hypercholesterolemia program and UB-312 PD program totaling $0.5 million.

General and administrative expenses were $5.5 million and $7.3 million for the three months ended September 30, 2023, and 2022, respectively.

The $1.8 million decrease was primarily due to a decrease in director and officer insurance expense of $0.5 million and decreases in personnel costs, consulting and professional services totaling $1.0 million.

Net loss for the three months ended September 30, 2023, was $13.1 million or $0.10 per share compared to $19.3 million or $0.15 per share for the three months ended September 30, 2022.
