Initial interim data show favorable drug exposure and confirm ALG.APV-527 biological activity Early promising signs of clinical activity in heavily pretreated patients Dose-escalation trial data on track for readout 2H 2024 LUND, SWEDEN and SEATTLE WA / ACCESSWIRE / March 7, 2024 / Alligator Bioscience AB ("Alligator") (ATORX) and Aptevo Therapeutics ("Aptevo") (Nasdaq:APVO) today announced positive interim data from the dose escalation phase of their Phase 1 trial evaluating ALG.APV-527 for the treatment of solid tumors likely to express the tumor antigen 5T4. The multi-center, dose escalation trial is now more than 50% enrolled, and preliminary results include: Treatment was overall well-tolerated, and a maximum tolerated dose has not yet been determined, dose-escalation in higher-dose cohorts is ongoing ALG.APV-527 could be measured in all patients with plasma concentration of ALG.APV-527 consistent with the administered dose Biomarker analyses indicate the expression of the targets (4-1BB and 5T4) in tumor biopsies and confirm biological activity of ALG.APV-527 Of particular interest, signs of clinical activity were observed for both enrolled patients with heavily pre-treated breast cancer. These patients demonstrated measurable level of drug in circulation (pharmacokinetic) and reproducible elevation of serum pharmacodynamic markers with dosing, suggesting the drug is biologically active. One patient remained on study for seven months and a second remains on study beyond nine months. Both patients achieved best overall response of stable disease. "I am pleased to share that we are now dosing cohort four, heading into higher dose ranges where we believe there is potential for increased signs of clinical activity based on preclinical models. We have treated patients with multiple tumor types including breast, pancreatic, non-small cell lung cancer and colorectal cancer. It is our belief that continued analysis of this cross section of tumor types will offer important insights about ALG.APV-527 that can be used to increase our success in later stage development," said Dirk Huebner, MD, Chief Medical Officer at Aptevo. "Additionally, as the trial has progressed, we have seen growing enthusiasm among our clinical sites, evidenced by a long and growing waiting list of patients who would like to participate in the study. We look forward to announcing additional data later in the year." "We're thrilled to share positive interim Phase 1 data from our trial with ALG.APV-527, a testament to our dedicated collaboration with Aptevo. The presence of both targets in tumor biopsies is a particularly encouraging finding, which underlines the potential of our novel bispecific antibody to treat multiple indications," said Sumeet Ambarkhane, MD, CMO at Alligator Bioscience. "We very much look forward to continuing this journey together, to make a meaningful impact in the fight against cancer." About the Trial The ALG.APV-527 Phase 1 trial is a multi-center, multi-cohort, open-label trial that will include six cohorts (dose levels) in a 3+3 design*. The trial will be conducted at up to 10 sites in the U.S. among adult patients with multiple solid tumor types/histologies likely to express the 5T4 antigen. ALG.APV-527 will be given intravenously once every two weeks. The trial will assess the safety and tolerability, pharmacokinetics, pharmacodynamics and preliminary anti-tumor activity of ALG.APV-527. *The 3+3 design proceeds in cohorts of three patients treated at increasing dose levels. Dose escalation stops when at least two out of three or six patients experience dose limiting toxicities or DLTs at that dose level. About ALG.APV-527 ALG.APV-527 is a bispecific conditional 4-1BB agonist, only active upon simultaneous binding to 4-1BB and 5T4. This has the potential to be clinically important because 4-1BB can stimulate the immune cells (antitumor-specific T cells and NK cells) involved in tumor control, making 4-1BB a particularly compelling target for cancer immunotherapy. 5T4 is an oncofetal tumor associated antigen overexpressed on numerous solid tumors including non-small-cell lung carcinoma (NSCLC), breast, head and neck, cervical, renal, gastric, and colorectal cancer. Preclinical studies, highlighting the differentiated design of the molecule that minimizes systemic immune activation, allowing for highly efficacious tumor-specific responses as demonstrated by potent activity in preclinical models, were recently published in the peer-reviewed publication, Molecular Cancer Therapeutics, a journal of the American Association for Cancer Research (AACR). About Alligator Bioscience Alligator Bioscience AB is a clinical-stage biotechnology company developing tumor-directed immuno-oncology antibody drugs. Alligator's portfolio includes several promising drug candidates, with the CD40 agonist mitazalimab as its key asset. Furthermore, Alligator is co-developing ALG.APV-527 with Aptevo Therapeutics Inc., several undisclosed molecules based on its proprietary technology platform, Neo-X-Prime™, and novel drug candidates based on the RUBY™ bispecific platform with Orion Corporation.

Announces 1H24 Plan for Development of Lead Candidate APVO436 for the Treatment of Frontline Acute Myeloid Leukemia, Interim Results Expected Late 2H24 ALG.APV-527 Phase 1 Trial for the Treatment of Multiple Solid Tumors Continues Enrollment, Interim Results Expected 1H24 SEATTLE, WA / ACCESSWIRE / March 5, 2024 / Aptevo Therapeutics Inc. (NASDAQ:APVO), a clinical-stage biotechnology company focused on developing novel immune-oncology therapeutics based on its proprietary ADAPTIR™ and ADAPTIR-FLEX™ platform technologies, today reported financial results for the year ended December 31, 2023 and provided a business update. Business Update APVO436 APVO436, Aptevo's CD3 x CD123 bispecific, is currently in clinical development for the treatment of acute myeloid leukemia (AML), of which there are approximately 20,000 new diagnoses and 11,000 deaths annually In 2023, the Company concluded a multi-center, multi-cohort dose expansion study. Trial results showed a 91% clinical benefit rate in combination with venetoclax + azacitidine in venetoclax naïve patients, a less than 30% incidence of CRS across all trial cohorts (the majority were grades 1 &2) and meaningful duration of remission, including three patients who transitioned to transplant after receiving therapy. Transplant is the best possible outcome for AML patients Upon review of this data and in consultation with the FDA, Aptevo intends to initiate an open- label Phase 1b/2 trial in 1H24 to further evaluate APVO436 in combination with the current standard of care, venetoclax + azacitidine, in frontline, venetoclax naïve AML patients The first part of the trial consists of a Phase 1b dose optimization study that will explore multiple doses of APVO436 in combination with venetoclax + azacitidine and is expected to add to the existing body of clinical data supporting further development of APVO436 in AML The Company plans to report interim data in late 2H24 "We are excited about our results and have compiled a significant body of data around APVO436 based on the trials we have completed to date. For example, we know it is safe, well tolerated, clinically active and shows a favorable duration of remission. For the next step in our APVO436 clinical program, we will target frontline AML patients who are venetoclax treatment naïve. Other populations that may benefit from APVO436, and therefore could be the focus of future clinical trials, include patients with relapsed/refractory AML and patients with myelodysplastic syndrome, both populations having been explored in earlier phases of APVO436 development. For the upcoming frontline trial, we know that the right combination is APVO436 + venetoclax + azacitidine and we have a targeted dose range. This upcoming Phase 1b/2 trial will allow us to further optimize and de-risk the regimen as it progresses to later stage development," said Marvin White , President and Chief Executive Officer at Aptevo. "We look forward to reporting early clinical results later in the year." ALG.APV-527 ALG.APV-527 is a 5T4 x 4-1BB bispecific currently being evaluated in a multi-cohort, multi-center Phase 1 dose escalation trial initiated in 2023 for multiple solid tumor types representing large patient populations with significant unmet medical needs The goal of the dose escalation trial is to evaluate safety and tolerability, and to evaluate the compound for signs of clinical activity ALG.APV-527 is designed to overcome the safety issues of other 4-1BB agonists by 5T4-dependent immune activation. In cytokine release assays performed as part of IND-enabling studies, the Company found no evidence of increased cytokine release, that can lead to potentially serious side effects, in vitro using human peripheral blood mononuclear cells or whole blood The Company believes ALG.APV-527 has the potential to be clinically important because 4-1BB can stimulate the immune cells (tumor-specific T cells and NK cells) involved in tumor control Aptevo expects to provide an interim data readout in 1H24 "We are pleased with the progress of the ALG.APV-527 Phase 1 clinical program. We believe this drug has the potential to impact patients in large patient populations that are significantly underserved by available treatment options," said Dirk Huebner, MD, Chief Medical Officer at Aptevo. " We look forward to reporting initial data in 1H24." 2023 Summary Financial Results Cash Position: Aptevo had cash and cash equivalents as of December 31, 2023, totaling $16.9 million. Royalty Revenue: Royalty revenue for the period covered by this report reflects revenue recorded only in the first quarter of 2022 due to our Amendment to Royalty Purchase Agreement with HCR. As a result of the amendment, we ceased reporting as royalty revenue, royalties paid by Pfizer to HCR related to Pfizer's sales of RUXIENCE® (rituximab-pvvr). The last quarter for which we reported this royalty revenue was Q1 2022. The Amendment had the effect of eliminating the requirement to report all future Pfizer non-cash royalty revenue and extinguishing the liability that we recorded upon the initial sale of the royalties to HCR. RUXIENCE is a registered trademark of Pfizer. Research and Development Expenses : Research and development expenses decreased by $0.8 million, from $17.9 million for the year ended December 31, 2022 to $17.1 million for the year ended December 31, 2023. The decrease was primarily due to lower spending on the APVO436 trial costs as we concluded our Phase 1b expansion study. The decrease was partially offset by higher spending on the ALG.APV-527 trial costs as 2023 consisted of a full year of CRO and patient visit costs compared to start-up activities in 2022. General and Administrative Expenses : General and administrative expenses decreased by $2.1 million, from $13.9 million for the year ended December 31, 2022 to $11.8 million for the year ended December 31, 2023. The decrease is primarily due to lower employee and consulting costs. Other Income (Expense) Net: Other Income (Expense) from Continuing Operations, Net consists of other income, net of $0.6 million for the year ended December 31, 2023 and other expense, net of $4.0 million for the year ended December 31, 2022. The change was primarily due to higher interest income from our money market funds and lower interest expense due to the principal paydown of our debt and full repayment of the outstanding balance in the first quarter of 2023. Additionally, we no longer record non-cash interest expense due to the amendment of our royalty purchase agreement with HCR in the second quarter of 2022, which eliminated the liability related to the sale of royalties and the related non-cash interest expense. Gain Related to Sale of Non-Financial Asset consists of a $9.7 million gain recorded in Q1 2023 related to the sale of all of the deferred payments and a portion of the milestone payments from Medexus to XOMA. Gain on extinguishment of liability related to sale of royalties covered by this report reflects a gain of $37.2 million recorded in 2022 due to our amended royalty Purchase agreement with HCR. Milestone income related to sale of royalties related to Pfizer's net sales of RUXIENCE in fiscal year 2022 prior to amendment of our royalty purchase agreement in Q2 2022. We did not record such income in 2023. Discontinued Operations: Income from discontinued operations was $1.2 million for the year ended December 31, 2023, consisting of $0.5 million in deferred payments from Medexus related to IXINITY sales and $0.2 million related to funds released from escrow from the sale of Aptevo BioTherapeutics in 2020. Additionally, we received $0.6 million related to the sale of hyperimmune business to Saol (later acquired by Kamada, Ltd.) as a result of the collection of certain accounts receivable. As a result of our Purchase Agreement with XOMA (US) LLC in March 2023, we no longer receive deferred payments from Medexus. We are still entitled to receive a percentage of future milestones based on Medexus' achievement of certain IXINITY net sales and regulatory approvals. Income from discontinued operations was $1.0 million for the year ended December 31, 2022, which related to collection of deferred payments from Medexus related to IXINITY sales. Net Income (Loss) : Aptevo had a net loss of $17.4 million or $1.42 per share for the year ended December 31, 2023, compared to a net income of $8.0 million or $1.57 per share for the corresponding period in 2022.
