Alligator Bioscience and Aptevo Therapeutics Announce Data from Phase 1 ALG.APV-527 Monotherapy Trial Showing 60% of Evaluable Patients Achieved Stable Disease in Solid Tumor Study

LUND, Sweden I September 16, 2024 I Alligator Bioscience AB (“Alligator”) (Nasdaq Stockholm: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 results, which include clinical activity, safety, tolerability outcomes, pharmacokinetics and pharmacodynamics were presented in a poster session on Saturday, September 14, 2024, at the European Society for Medical Oncology (ESMO) Annual Congress in Barcelona, Spain. ALG.APV-527 is a first-in-class bispecific antibody that targets 4-1BB and the tumor antigen 5T4. The compound is being evaluated in a multi-center, dose escalation trial that has 18 patients included in the safety analysis. These patients received multiple prior rounds of therapy for the treatment of solid tumor types. The trial is approaching full enrollment and interim results include: Clinical Activity/Efficacy Safety and Tolerability Evidence of favorable pharmacokinetics and biological activity of ALG.APV-527 “4-1BB has been a target of interest-though with excess toxicity-for decades, and novel bispecific approaches like this will enable us to maximize anti-tumor immunity while limiting the systemic toxicity concerns that have plagued this key immune costimulatory receptor. With this backdrop, these Phase 1 interim results are very encouraging, with ALG.APV-527 showing a positive safety profile with 60% of evaluable patients achieving stable disease, meaning not progressing for variable time frames including one breast cancer patient being treated with monotherapy on study with SD for more than 11 months. We are excited to see signs of clinical activity, underscoring the potential of the drug to benefit patients with solid tumors in the clinical setting, supported by a positive safety and tolerability profile,” stated Thomas Marron, MD, PhD, Professor in Immunology & Immunotherapy and in Medicine, Hematology and Medical Oncology at Icahn School of Medicine at Mount Sinai , participating Investigator of the trial. Trial Overview The ALG.APV-527 Phase 1 trial is a multi-center, multi-cohort, open-label dose-escalation trial that includes administration of ALG.APV-527 in up to six escalating dose levels in a 3+3 design*. The trial is enrolling 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 is assessing 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 (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, has been 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.

Alligator Bioscience's Phase 2 mitazalimab Pancreatic Cancer Data Published in The Lancet Oncology

LUND, SE / ACCESSWIRE / June 03, 2024 / Alligator Bioscience (STO:ATORX) Publication in world-leading clinical oncology journal validates the quality and potential implications of Phase 2 OPTIMIZE-1 results The study reported Objective Response Rate (ORR) of 40.4% in 57 evaluable patients, primary endpoint was met. The novel combination of mitazalimab and mFOLFIRINOX and the unique dosing schedule resulted in an unprecedented Duration of Response (DoR, median 12.5 months) together with a prolonged Overall Survival (OS, median 14.3 months). These results compare favorably to the historically reported outcomes for FOLFIRINOX alone and most other standard of care or investigational therapies. These data were also presented at the ASCO annual meeting on June 1; updated data with longer follow-up are expected end of June 2024. Lund, Sweden - Alligator Bioscience (Nasdaq Stockholm: ATORX) today announced the publication of positive Phase 2 data on its lead drug candidate mitazalimab in first line metastatic pancreatic cancer in The Lancet Oncology . The journal is an internationally trusted source of clinical, and global health knowledge. With an Impact Factor of 51.1, it is the world-leading clinical oncology research journal. With a 5-year overall survival rate of less than 5%, current systemic therapies for metastatic pancreatic ductal adenocarcinoma (mPDAC) are associated with poor outcomes. Data presented in The Lancet Oncology, from the OPTIMIZE-1 trial of mitazalimab in combination with mFOLFIRINOX, showed a confirmed ORR of 40.4% in 57 evaluable patients (unconfirmed ORR was 50.9%). Median DoR was 12.5 months and the median OS was 14.3 months. Median Progression Free Survival (PFS) was 7.7 months. These data compare favorably to the historically reported outcomes with FOLFIRINOX (ORR 31.6%, mDoR 5.9 months, mOS 11.1 months and mPFS 6.4 months) [1] . The recently approved new treatment regimen of NALIRIFOX was associated with an ORR of 42%, mDoR of 7.3 months, mPFS 7.4 months and a mOS of 11.1 months. [2] "The long-lasting responses and related biomarker associations reported in OPTIMIZE-1 are highly encouraging, demonstrating a critical immunomodulatory contribution of mitazalimab. The increase in ORR and PFS, compared to FOLFIRINOX alone, are superior outcomes and we believe that the reported depth and duration of response are strong indicators that the observed increases in survival will remain evident," said Prof. Jean-Luc van Laethem, Head of the Digestive Oncology Department of Erasme Hospital (ULB) Brussels, Principal Investigator of the OPTIMIZE-1 trial and lead author of the article in The Lancet Oncology. "Furthermore, mitazalimab showed a favorable safety pro it could offer better quality of life for pancreatic patients who currently have few treatment options. The data from OPTIMIZE-1 are very promising and are strongly supportive of the continued development of mitazalimab and mFOLFIRINOX in mPDAC, in a confirmatory trial." OPTIMIZE-1 , an open-label, single-arm, multicenter, Phase 1b/2 study, assessed the safety and efficacy of mitazalimab (CD40 mAb agonist) in combination with standard of care chemotherapy mFOLFIRINOX. The DoR and OS are expected to improve further, as a majority of the patients were still alive at the time of the analysis (cut-off date November 2023). The OPTIMIZE-1 results compare favorably to the previously reported outcomes with FOLFIRINOX[1] as well as more recently reported data of the NALIRIFOX regimen in the NAPOLI 3 Phase 3 trial[2]. The OS at 12 months in OPTIMIZE-1 was 59.3%, compared to 48.1% for FOLFIRINOX[1] and 45.6% for NALIRIFOX[2]. "This publication in The Lancet Oncology is an important validation of the highly promising results of our OPTIMIZE-1 mitazalimab study. A substantial number of patients were either in the treatment or in the follow-up at the time of the primary analysis . Consequently, the 18-month survival follow-up data, which we expect at the end of June 2024, should provide further important insights into the potential of mitazalimab," said Søren Bregenholt, CEO of Alligator Bioscience.

It is expected to become the second leading cause of cancer death in the western world by 2030. There are about 200,000 annual cases in the U.S. and the EU, with very poor prognosis: five-year survival is about 10% and median survival about 6 months. For 80% of patients, the only option is chemotherapy that offers only marginal benefit. FOLFIRINOX is expected to be the preferred first line regimen in the U.S. and the EU for patients with good performance status.
