WAYNE, Pa., Nov. 06, 2025 (GLOBE NEWSWIRE) -- Avalo Therapeutics, Inc. (Nasdaq: AVTX), a clinical stage biotechnology company fully dedicated to developing IL-1β-based treatments for immune-mediated inflammatory diseases, today announced business updates and financial results for the third quarter of 2025.

“Now that enrollment is complete, we’re fully focused on completing the LOTUS trial, preparing for the data readout in mid-2026, and progressing our Phase 3 planning,” said Dr. Garry Neil, Chief Executive Officer. “This marks an important transition for Avalo as we turn our focus from enrollment to completion of the trial, guided by strong conviction in AVTX-009’s high-affinity inhibition of IL-1β and its potential to deliver meaningful benefit for people living with hidradenitis suppurativa.”

Recent Corporate Highlights and Upcoming Anticipated Milestones:

• Announced completion of enrollment of the Phase 2 LOTUS trial. The global trial includes approximately 250 adults with moderate to severe hidradenitis suppurativa to evaluate the efficacy and safety of subcutaneous bi-weekly and monthly dosing regimens compared to placebo.

  • Topline data expected in mid-2026.

• Appointed Kevin Lind to the Board of Directors. Mr. Lind brings extensive leadership experience spanning financial and corporate strategy as well as business development execution at development-stage biotech companies.

• Expanded leadership team with the appointment of Taylor Boyd as Chief Business Officer and Ashley Ivanowicz as Senior Vice President, Human Resources.

Third Quarter 2025 Financial Update:

• Cash, cash equivalents and short-term investments were $111.6 million as of September 30, 2025. Net cash used in operating activities was $37.2 million for the nine months ended September 30, 2025. The Company’s current cash, cash equivalents and short-term investments are expected to fund operations into 2028.
  

• Research and development expenses were $13.6 million for the third quarter of 2025, an increase of $4.1 million from the third quarter of 2024, driven by costs related to and supporting the Phase 2 LOTUS trial.
  

• General and administrative expenses were $5.6 million for the third quarter of 2025, an increase of $1.3 million from the third quarter of 2024, primarily driven by stock-based compensation expense.
  

• Net loss was $30.6 million for the third quarter of 2025, as compared to net income of $23.0 million for the third quarter of 2024. The difference was driven by a $47.3 million change in other expenses from the prior period primarily related to the warrants issued in the March 2024 private placement, all of which were fully exercised in 2024. Additionally, research and development expenses increased $4.1 million, as discussed above. Basic and diluted net loss per share was $2.19 for the third quarter of 2025 compared to basic net income per share of $0.98 for the third quarter of 2024, based on 14,000,451 weighted average common shares outstanding and 5,546,257 weighted average basic common shares outstanding, respectively. Diluted net loss per share for the third quarter of 2024 was $2.83, based on 10,784,037 weighted average diluted common shares outstanding.

About Avalo Therapeutics

Avalo Therapeutics is a clinical stage biotechnology company fully dedicated to developing IL-1β-based treatments for immune-mediated inflammatory diseases. Our lead asset, AVTX-009, is in a Phase 2 clinical trial for hidradenitis suppurativa (HS). We’re also exploring additional opportunities to make an impact in prevalent indications that have significant remaining unmet needs. For more information about Avalo, please visit www.avalotx.com.

About AVTX-009 

AVTX-009 is a humanized monoclonal antibody (IgG4) that binds to interleukin-1β (IL-1β) with high affinity and neutralizes its activity. IL-1β is a pro-inflammatory cytokine that plays a central role in the pathogenesis of a wide range of human diseases.¹ It activates immune cells that generate proinflammatory cytokines, including IL-6, TNF-α, and IL-17. Dysregulated IL-1β signaling is a major driver of inflammation, contributing to the progression of autoimmune disorders. IL-1β inhibition has proven effective in multiple immune-mediated inflammatory diseases.^1-3

About the LOTUS Trial

The LOTUS trial is a randomized, double-blind, placebo-controlled, parallel-group Phase 2 trial with two AVTX-009 dose regimens to evaluate the efficacy, safety and tolerability of AVTX-009 in approximately 250 adults with moderate to severe hidradenitis suppurativa. Subjects were randomized (1:1:1) to receive either one of two dosing regimens of AVTX-009 or placebo during a 16-week treatment phase. The primary efficacy endpoint is the proportion of subjects achieving Hidradenitis Suppurativa Clinical Response (HiSCR75) at Week 16. Secondary objectives include but are not limited to: the proportion of patients achieving HiSCR50 and HiSCR90 as well as change from baseline in: International HS Severity Score System (IHS4), draining fistula count, abscess and inflammatory nodule (AN) count, and patients achieving at least a 30% reduction on a numerical rating scale in Patient's Global Assessment of Skin Pain (PGA Skin Pain). For additional information this trial (NCT06603077), please visit www.clinicaltrials.gov or www.lotustrial.com.

About Hidradenitis Suppurativa

Hidradenitis suppurativa (HS) is a chronic, progressive, often debilitating inflammatory skin disease that causes painful nodules, abscesses, and tunnels to form under the skin.^4-6,8 Areas commonly affected by HS include the nape of the neck, breasts, chest, armpits, abdomen, buttocks and anus, groin and genitals, and inner thighs.⁷ If not adequately and promptly treated, the chronic inflammation characteristic of HS may progress to tissue destruction and permanent scarring.^4-6,9 HS typically first presents in late adolescence or early adulthood and is estimated to affect 0.7–1.2% of the U.S. population, though some sources suggest the prevalence may be as high as 2–4%.^10,11,12
