Avalo Reports Third Quarter 2023 Financial Results and Provides Business Updates

Successfully eliminated $35 million debt paving the way for future growth and innovation
Divested AVTX-800 series for potential milestone payments of $45 million, fully focusing the pipeline on Avalo’s promising immunology assets
Disclosed improved cash of approximately $10.2 million as of September 30, 2023

WAYNE, PA AND ROCKVILLE, MD, November 9, 2023 — Avalo Therapeutics, Inc. (Nasdaq: AVTX), today announced business updates and financial results for the third quarter of 2023.

Dr. Garry Neil, Chief Executive Officer and Chairman of the Board remarked, “We made significant progress in the third quarter, highlighted by the full debt payoff and divestiture of the 800 series. Our strengthened balance sheet and focused pipeline underscores our unwavering commitment to execute our strategy to progress our promising immunology drug candidates and positions us to consider collaborations, pursue funding for research and development, and bring innovative treatments to market.”

Dr. Neil continued, “I am excited to potentially kick off a randomized placebo-controlled trial of quisovalimab, our anti-LIGHT mAb, in patients with ulcerative colitis or another inflammatory indication, subject to funding. This drug candidate has previously shown strong target engagement in both acute and chronic inflammatory diseases, and I remain optimistic that it could transform the lives of patients with immunological diseases and address unmet medical needs. Additionally, we look forward to progressing AVTX-008, our BTLA agonist fusion protein with high-binding affinity and serum stability, to IND. Targeting BTLA represents a promising and increasingly recognized avenue for developing therapies that can effectively modulate the immune response in autoimmune diseases while minimizing the risk of systemic immunosuppression. We believe AVTX-008 is unique in this class because it is a fusion protein that utilizes the natural ligand thus avoiding potential problems with agonist mAbs. Finally, we continue to evaluate new opportunities to further augment our immunology pipeline.”

Corporate Updates:

In September of 2023, Avalo paid off the remaining $14.3 million of its original $35 million debt owed to Horizon Technology Finance Corporation (Nasdaq: HRZN). As a result, Avalo’s obligations under the debt agreement were deemed satisfied.

On October 27, 2023, Avalo completed the divestiture of its rights, title and interest in, assets relating to AVTX-801, AVTX-802 and AVTX-803 (collectively, the 800 Series) to AUG Therapeutics, LLC (AUG). The Company is entitled to up to $45 million of contingent milestone payments. The Company previously announced it entered into a purchase agreement with AUG to divest the 800 Series on September 12, 2023.

Program Updates:

Quisovalimab (AVTX-002): Anti-LIGHT monoclonal antibody (mAb) targeting immune-inflammatory diseases.
Quisovalimab has shown a rapid and sustained reduction of LIGHT levels, as well as a favorable safety and tolerability profile, in all indications studied including COVID-19 Acute Respiratory Distress Syndrome (ARDS), Crohn’s Disease and Non-Eosinophilic Asthma (NEA).

Quisovalimab was statistically significant in reducing respiratory failure and mortality in patients hospitalized with COVID-19 ARDS in a randomized placebo-controlled trial. Quisovalimab also demonstrated positive trends in an open-label study in Crohn’s Disease.

A post-hoc analyses in the PEAK Trial showed a sub-population of NEA patients with baseline LIGHT levels over 125 pg/mL, which represented over 50% of patients, had an approximate 50% reduction in asthma-related events (AREs) for patients treated with quisovalimab compared to placebo.

Avalo is pursuing funding for the program and is considering a randomized placebo-controlled trial in patients with Ulcerative Colitis or other inflammatory conditions.

AVTX-008: B and T Lymphocyte Attenuator (BTLA) agonist fusion protein targeting immune dysregulation disorders.
AVTX-008 is uniquely positioned as a fusion protein with high-binding affinity and serum stability. It utilizes the natural ligand thus it may avoid the potential problems with agonist mAbs.

Avalo previously identified a lead molecule, is evaluating several immune dysregulation disorders to pursue and plans to rapidly progress the asset to IND, subject to funding.

Third Quarter 2023 Financial Update:

Avalo had $10.2 million in cash and cash equivalents as of September 30, 2023. The Company fully eliminated its debt with principal payments of $21.2 million, inclusive of the full payoff of the remaining loan in September of 2023. The Company raised $46.2 million of net proceeds from equity financings in the nine months ended September 30, 2023.

Total operating expenses decreased $24.7 million for the nine months ended September 30, 2023 as compared to the same period in 2022. This decrease was primarily driven by decreases to both research and development expenses and selling, general and administrative as a result of cost savings initiatives implemented in the first quarter of 2022 and fewer research and development programs ongoing in the current year.

The net loss and net loss per share for the nine months ended September 30, 2023 was largely driven by operating expenses. The significant decrease in net loss for the nine months ended September 30, 2023 as compared to the prior year period was due to the $24.7 million decrease in operating expenses, partially offset by the $14.5 million of license revenue in the prior year that did not repeat. Net loss per share decreased as a result of the decrease in net loss and due to a significant increase in shares outstanding.

About quisovalimab (AVTX-002)

Quisovalimab is a fully human monoclonal antibody (mAb), directed against human LIGHT (Lymphotoxin-like, exhibits Inducible expression, and competes with Herpes Virus Glycoprotein D for Herpesvirus Entry Mediator (HVEM), a receptor expressed by T lymphocytes). There is increasing evidence that the dysregulation of the LIGHT-signaling network which includes LIGHT, its receptors HVEM and LTβR and the downstream checkpoint BTLA, is a disease-driving mechanism in autoimmune and inflammatory reactions in barrier organs. Therefore, we believe reducing LIGHT levels can moderate immune dysregulation in many acute and chronic inflammatory disorders. Quisovalimab previously demonstrated proof of concept in COVID-19 induced acute respiratory distress syndrome including reduction in mortality and respiratory failure, as well as a positive signal in patients with Crohn’s Disease.

About AVTX-008

AVTX-008 is a fully human B and T Lymphocyte Attenuator (BTLA) agonist fusion protein in the IND-enabling stage. AVTX-008 is differentiated by having specific binding to BTLA, with no binding to LIGHT or CD160. AVTX-008 also has high-serum stability and solubility.

About Avalo Therapeutics

Avalo Therapeutics is a clinical stage biotechnology company focused on the treatment of immune dysregulation by developing therapies that target the LIGHT-signaling network.

LIGHT and its signaling receptors, HVEM (TNFRSF14), and lymphotoxin β receptor (TNFRSF3), form an immune regulatory network with two co-receptors of herpesvirus entry mediator, checkpoint inhibitor B and T Lymphocyte Attenuator (BTLA), and CD160 (the LIGHT-signaling network). Accumulating evidence points to the dysregulation of the LIGHT network as a disease-driving mechanism in autoimmune and inflammatory reactions in barrier organs. Therefore, we believe reducing LIGHT levels can moderate immune dysregulation in many acute and chronic inflammatory disorders.
