Acquired AVTX-009, Phase-2 ready anti-IL-1β mAb, in March 2024 Increased cash position with private placement financing in March 2024 providing up to $185 million, including initial upfront investment of $115.6 million Topline results from planned Phase 2 trial of AVTX-009 in hidradenitis suppurativa expected in 2026 Expected cash runway into 2027 WAYNE, Pa. and ROCKVILLE, Md., March 29, 2024 (GLOBE NEWSWIRE) -- Avalo Therapeutics, Inc. (Nasdaq: AVTX), today announced business updates and year-end financial results for 2023. “We are very excited about the acquisition of AVTX-009 and concurrent financing of up to $185 million, $115.6 million of which we received upfront. The progress we made in 2023 to strengthen our balance sheet helped enable these transactions. I am proud of the team’s efforts and continued dedication in executing our strategy focused on the treatment of inflammatory conditions,” said Dr. Garry Neil, Chief Executive Officer and Chairman of the Board. “Our focus in 2024 is executing operationally on the development of AVTX-009 for the treatment of hidradenitis suppurativa. Our experienced team is ready to hit the ground running on progressing the drug candidate and is motivated by the potential of developing a meaningful treatment for patients suffering from hidradenitis suppurativa, many of whom are searching for improved treatment options.” Corporate Updates On March 27, 2024, Avalo acquired AVTX-009, a Phase 2 ready anti-IL-1β mAb, through an acquisition of AlmataBio, Inc. The consideration included stock valued at $15 million, as well as a $7.5 million payment due upon closing of the private placement investment. Avalo is also required to pay development milestones to the former AlmataBio stockholders including $5 million due upon the first patient dosed in a Phase 2 trial in patients with hidradenitis suppurativa (HS) and $15 million due upon the first patient dosed in a Phase 3 trial, both of which are payable in cash, Avalo stock, or a combination thereof at the election of the former AlmataBio stockholders. On March 28, 2024, Avalo closed a private placement led by Commodore Capital and TCGX, with participation from BVF Partners, Deep Track Capital, OrbiMed, Petrichor, and RA Capital Management for gross proceeds of up to $185 million, including $115.6 million of initial upfront funding received at close. The upfront investment is expected to fund operations through Avalo’s planned Phase 2 data readout in hidradenitis suppurativa and into 2027. As part of the private placement, the Company issued (i) an aggregate of $115.6 million of non-voting convertible preferred stock and (ii) warrants to purchase Avalo’s common stock or an equivalent amount (as converted to common stock) of non-voting convertible preferred stock for an aggregate exercise price of $69.4 million. The warrants are exercisable for approximately $5.80 per underlying share of common stock until the earlier of five years from the date of issuance or 30 days after the public announcement of the first patient dosed in a Phase 2 trial of AVTX-009 in HS. On an as-converted basis and after accounting for the financing and acquisition (excluding the exercise of the warrants), the total number of shares of Avalo common stock outstanding would be approximately 23.4 million immediately after the closing of the transactions. Program Updates and Milestones: AVTX-009: Anti-IL-1β monoclonal antibody (mAb) targeting inflammatory diseases. Avalo intends to pursue the development of AVTX-009 in hidradenitis suppurativa and expects topline data from its planned Phase 2 trial in hidradenitis suppurativa in 2026. In addition to hidradenitis suppurativa, Avalo intends to develop AVTX-009 in at least one other chronic inflammatory indication. Quisovalimab (AVTX-002): Anti-LIGHT mAb targeting immune-inflammatory diseases. Avalo is conducting a strategic review of the quisovalimab program. AVTX-008: B and T Lymphocyte Attenuator (BTLA) agonist fusion protein targeting immune dysregulation disorders. Avalo is conducting a strategic review of the AVTX-008 program. 2023 Financial Update: As of December 31, 2023, Avalo had $7.4 million in cash and cash equivalents. We raised approximately $46.2 million of net proceeds from equity financings in 2023 and fully retired our original $35 million of debt with principal payments of $21.2 million, inclusive of the full payoff of the loan in September 2023. The decrease in net loss was primarily attributable to a $26.2 million decrease in operating expenses driven by significantly reduced research and development expenses and selling, general and administrative expenses partially offset by a decrease of $14.2 million in license and other revenue. The significant reduction of research and development expenses was driven by fewer development programs ongoing during 2023 (due to divestitures in both 2022 and 2023), the AVTX-002 trial reading out in June of 2023 with no new trials initiated in the second half of the year, and a reduction of manufacturing costs due to the timing of manufacturing runs. Selling, general and administrative expenses decreased due to a smaller infrastructure to support the focused pipeline, severance in 2022 that did not repeat, as well as cost savings initiatives. Net loss per share decreased as a result of the decrease in net loss and due to an increase in the shares outstanding. In March 2024, we closed a private placement financing for gross upfront proceeds of $115.6 million. Avalo estimates upfront net proceeds of approximately $105 million after deducting estimated transaction fees and expenses from both the private placement financing and the acquisition of AlmataBio. We expect future research and development expenses and cash used in operating activities to increase in 2024 as a result of our development plans to initiate and progress a Phase 2 trial in hidradenitis suppurativa. Topline results from this planned Phase 2 trial are expected in 2026 and the upfront funding is expected to fund operations through this data readout and into 2027.

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 central driver in the inflammatory process. Overproduction or dysregulation of IL-1β is implicated in many autoimmune and inflammatory diseases. IL-1β is a major, validated target for therapeutic intervention. There is evidence that inhibition of IL-1β could be effective in hidradenitis suppurativa and a variety of inflammatory diseases in dermatology, gastroenterology, and rheumatology. 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. Avalo’s lead asset is AVTX-009, an anti-IL-1β mAb, targeting inflammatory diseases. Avalo’s pipeline also includes quisovalimab (anti-LIGHT mAb) and AVTX-008 (BTLA agonist fusion protein).

Successfully eliminated $35 million debt paving the way for future growth and innovationDivested AVTX-800 series for potential milestone payments of $45 million, fully focusing the pipeline on Avalo’s promising immunology assetsDisclosed improved cash of approximately $10.2 million as of September 30, 2023 WAYNE, Pa. and ROCKVILLE, Md., Nov. 09, 2023 (GLOBE NEWSWIRE) -- 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 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. For more information about Avalo, please visit www.avalotx.com.
