Medicenna Announces Oral Presentation of MDNA11 Data from the Phase 1/2 ABILITY-1 Study at the 2024 ASCO Annual Meeting
Oral presentation of MDNA11’s Phase 1/2 ABILITY-1 Study will feature new and updated clinical data
Updated bizaxofusp survival results from the Phase 2b recurrent glioblastoma trial versus propensity matched external control arm will also be presented as a poster
TORONTO and HOUSTON, April 24, 2024 (GLOBE NEWSWIRE) -- Medicenna Therapeutics Corp. (“Medicenna” or the “Company”) (TSX: MDNA, OTCQB: MDNAF), a clinical-stage immunotherapy company focused on the development of Superkines, announced today that it will be presenting two abstracts, including an oral podium presentation, at the Annual Meeting of the American Society of Clinical Oncology ("ASCO") to be held in Chicago from May 31 – June 4, 2024.
The oral podium presentation will include new clinical data from the ongoing Phase 1/2 ABILITY-1 Study evaluating MDNA11, a long-acting ‘beta-enhanced not-alpha’ interleukin-2 (IL-2) super-agonist, as both a monotherapy and in combination with pembrolizumab (KEYTRUDA®) in patients with advanced or metastatic solid tumors.
Details of the podium presentation are as follows:
Title: “Results from ABILITY-1 Monotherapy Dose Escalation Study with MDNA11, an Engineered Long-acting IL-2 agonist, in patients with advanced solid tumors”
Abstract #: 2508
Abstract Session: Developmental Therapeutics – Immunotherapy
Date and Time: June 3, 2024; 11:30 AM-2:30 PM CDT
Presenter: Dr Victoria G. Atkinson, MBBS, FRACP, Gallipoli Medical Research Foundation, Greenslopes Private Hospital, and Princess Alexandra Hospital, University of Queensland, Australia.
The second abstract will provide new data analyses for bizaxofusp (formerly known as MDNA55) survival outcomes compared to a propensity matched external control arm (ECA) in nonresectable recurrent glioblastoma (rGBM).
Details of the poster presentation are as follows:
Title: "Phase 2 Study of Bizaxofusp, an IL-4R Targeted Toxin Payload, in Nonresectable Recurrent GBM: Comparison of Overall Survival with Contemporaneous Eligibility-Matched and Propensity Score Balanced External Control Arm"
Abstract #: 2709
Abstract Session: Poster Session – Central Nervous System Tumors
Date and Time: June 1, 2024; 9:00 AM-12:00 PM CDT

About MDNA11
MDNA11 is a long-acting ‘beta-enhanced not-alpha’ interleukin-2 (IL-2) Superkine specifically engineered to overcome the shortcomings of aldesleukin and other next generation IL-2 variants by preferentially activating immune effector cells (CD4+ T, CD8+ T and NK cells) responsible for killing cancer cells, with minimal or no stimulation of immunosuppressive Tregs. These unique proprietary features of the IL-2 Superkine have been achieved by incorporating seven specific mutations and genetically fusing it to a recombinant human albumin scaffold to improve the pharmacokinetic (PK) profile and pharmacological activity of MDNA11 due to albumin’s natural propensity to accumulate in highly vascularized sites, in particular tumor and tumor draining lymph nodes. MDNA11 is currently being evaluated in the Phase 1/2 ABILITY-1 study as both a monotherapy and in combination with pembrolizumab (KEYTRUDA®).
About the ABILITY-1 Study
The ABILITY-1 study (NCT05086692) is a global, multi-center, open-label study that assesses the safety, tolerability, pharmacokinetics, pharmacodynamics and anti-tumor activity of MDNA11 as monotherapy or in combination with pembrolizumab (KEYTRUDA®). In the combination dose escalation of the Phase 2 study, approximately 6-12 patients are expected to be enrolled and administered ascending doses of MDNA11 intravenously once every two weeks in combination with pembrolizumab. This portion of the study includes patients with a wide range of solid tumors with the potential for susceptibility to immune modulating therapeutics. Upon identification of an appropriate dose regimen for combination, the study will proceed to a combination dose expansion cohort.
About Bizaxofusp
Bizaxofusp (formerly known as MDNA55) is Medicenna’s IL-4 Empowered Superkine that has been studied in 5 clinical trials in over 130 patients, including a Phase 2b trial in patients with recurrent glioblastoma (rGBM), the most common and uniformly fatal form of brain cancer. Results from the Phase 2b study, which were published in the journal Neuro-Oncology® (Sampson, et al. June 2023), demonstrated that bizaxofusp more than doubled the median survival in end-stage rGBM patients when compared to a well-matched external control arm. Medicenna has obtained agreement from the U.S. FDA on the study design for the registrational Phase 3 LIGHT (Localized Infusion for the treatment of recurrent Glioblastoma with High-dose bizaxofusp Therapy) trial and the Company is actively pursuing potential partnerships to conduct the LIGHT trial, and if approved, bizaxofusp’s commercialization in key global markets. Bizaxofusp has been granted FastTrack and Orphan Drug status from the FDA and FDA/EMA, respectively.
About Medicenna
Medicenna is a clinical-stage immunotherapy company focused on developing novel, highly selective versions of IL-2, IL-4 and IL-13 Superkines and first-in-class Empowered Superkines. Medicenna’s long-acting IL-2 Superkine, MDNA11, is a next-generation IL-2 with superior affinity toward CD122 (IL-2 receptor beta) and no CD25 (IL-2 receptor alpha) binding, thereby preferentially stimulating cancer-killing effector T cells and NK cells. Medicenna’s IL-4 Empowered Superkine, bizaxofusp (formerly MDNA55), has been studied in 5 clinical trials enrolling over 130 patients, including a Phase 2b trial for recurrent GBM, the most common and uniformly fatal form of brain cancer. Bizaxofusp has obtained FastTrack and Orphan Drug status from the FDA and FDA/EMA, respectively. Medicenna’s early-stage BiSKITs (Bifunctional SuperKine ImmunoTherapies) and the T-MASK (Targeted Metalloprotease Activated SuperKine) programs are designed to enhance the ability of Superkines to treat immunologically “cold” tumors.
