With the Response Rate increasing to 23%, MDNA11 continues to show compelling single-agent activity in the ABILITY-1 study amongst high-dose phase-2 eligible patients (N=13) that failed checkpoint inhibitor therapies, while maintaining an acceptable safety profile
Tumor shrinkage was also observed in all high-dose phase-2 eligible patients with stable disease (SD). In addition to a new PR, the clinical benefit rate (PR plus SD for over 24 weeks) and tumor control rate (PR plus all SD) increased to 46% and 69%, respectively
First patient was dosed in Phase 1 combination escalation portion of the ABILITY Study evaluating MDNA11 with KEYTRUDA® (pembrolizumab)
Additional monotherapy data updates and preliminary combination escalation and expansion data to be shared in H1 and H2 of 2024
Cash runway extended through multiple data readouts and into Q2 of calendar 2025
TORONTO and HOUSTON, Feb. 14, 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, today announced financial results and corporate highlights for the third quarter of fiscal 2024, ended December 31, 2023, and outlined its strategic outlook for 2024.
“We are off to a solid start in 2024 with further validation of single-agent anti-tumor activity of our IL-2 super-agonist, MDNA11, in the ABILITY-1 study,” said Dr. Fahar Merchant, President and CEO of Medicenna. “We are encouraged by another PR, increasing the total number of PRs to 3 in patients with prior failure from immune checkpoint therapy. With response rates above 20% at this early stage of the trial in high-dose phase-2 eligible patients, we believe that MDNA11’s differentiated mechanism demonstrates its clinical superiority to competing IL-2 programs. This is especially gratifying in view of the desirable safety, pharmacokinetic and pharmacodynamic characteristics observed to date. We look forward to reporting additional monotherapy dose expansion and combination escalation and expansion data from the ABILITY-1 study during H1 and H2 2024.”
Dr. Merchant continued, “We believe 2024 will be a transformational year for Medicenna as we continue advancing our mid- and late-stage MDNA11 and bizaxofusp assets for patients battling difficult to treat cancers. The global multi-arm Phase 1/2 ABILITY-1 study is expanding to various cancer centers in the US, Canada, Australia, South Korea and Europe evaluating MDNA11 as a single-agent and in combination with KEYTRUDA® in patients with advanced solid tumors. For bizaxofusp, we plan to seek Breakthrough Therapy Designation from the FDA, in addition to securing alignment with the EMA for the Phase 3 trial design supported by the FDA. These endeavors will further enhance potential partnership activities for bizaxofusp. We are excited for the year ahead and are increasingly confident about the significant potential of our evolutionary cytokines and delivering on our mission to bring revolutionary medicines to patients.”
PROGRAM AND BUSINESS UPDATE:
Highlights for the three months ended December 31, 2023, along with recent developments include:
MDNA11
Bizaxofusp (MDNA55)

Financial Results
As of December 31, 2023, cash and cash equivalents were $21.8 million, compared to $25.7 million on September 30, 2023.
Net loss for the quarter ended December 31, 2023, was $5.0 million or ($0.07) per share compared to a net loss of $1.1 million or ($0.02) per share for the quarter ended December 31, 2022. The increase was primarily a result of a reduction in the non-cash gain related to the change in valuation of the Company’s derivative warrant liability.
Research and development expenses of $3.0 million were incurred during the quarter ended December 31, 2023, compared with $2.9 million incurred in the quarter ended December 31, 2022. Higher clinical costs associated with the MDNA11 ABILITY-1 study relative to the prior year quarter were mostly offset by reductions in stock-based compensation and licensing fees.
General and administrative expenses of $1.8 million were incurred during the quarter ended December 31, 2023, compared with $2.0 million during the quarter ended December 31, 2022. The decrease in general and administrative expenses in the current quarter is primarily related to a reduction in directors’ and officers’ liability insurance premiums.
Medicenna’s interim consolidated financial statements for the three and nine months ended December 31, 2023, and the related management’s discussion and analysis (MD&A) are available on SEDAR+ at www.sedarplus.ca and EDGAR.
About Medicenna Therapeutics
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.
