TORONTO and HOUSTON, Dec. 22, 2021 (GLOBE NEWSWIRE) -- Medicenna Therapeutics Corp. (“Medicenna” or “the Company”) (NASDAQ: MDNA TSX: MDNA), a clinical stage immuno-oncology company, today announced preliminary data from the Phase 1/2 ABILITY (A Beta-only IL-2 ImmunoTherapY) study of MDNA11, the Company’s selective, long-acting and novel IL-2 super-agonist.
Key findings from the ABILITY study’s first two dose escalation cohorts, which evaluated MDNA11 monotherapy in patients with advanced malignancies and administered intravenously once every two weeks, include the following:
“These preliminary clinical data represent an important step towards demonstrating how MDNA11’s differentiated ‘beta-only’ approach positions it as a potentially best-in-class IL-2 cytokine in development,” said Fahar Merchant, PhD., President and Chief Executive Officer of Medicenna. “Patients in the ABILITY study’s first two cohorts have not displayed major safety issues while showing increases in anti-cancer immune cells that could be further enhanced as we evaluate higher doses of MDNA11 in subsequent dose escalation cohorts. We are very pleased with the ABILITY study’s early results to date and are on track to provide additional updates on safety, pharmacokinetic, and pharmacodynamic data next quarter with initial efficacy results anticipated in mid-2022.”
The ABILITY (A Beta-only IL-2 ImmunoTherapY) study is designed to assess the safety, pharmacokinetics, pharmacodynamics, and anti-tumor activity of various doses of intravenously administered MDNA11 in patients with advanced, relapsed, or refractory solid tumors. The trial includes an MDNA11 monotherapy arm, as well as a combination arm designed to evaluate MDNA11 with a checkpoint inhibitor. Approximately 80 patients are expected to be enrolled into the ABILITY Study. Following establishment of the recommended Phase 2 dose (RP2D) and optimal treatment schedule in the study’s dose escalation phase, Medicenna plans to conduct a dose expansion phase that will enroll patients with renal cell carcinoma, melanoma, and other solid tumors in monotherapy and combination settings.
Medicenna is a clinical stage immunotherapy company focused on the development of 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 CD122 (IL-2 receptor beta) binding without CD25 (IL-2 receptor alpha) affinity thereby preferentially stimulating cancer killing effector T cells and NK cells. Medicenna’s early-stage BiSKITs™ program, (Bifunctional SuperKine ImmunoTherapies) is designed to enhance the ability of Superkines to treat immunologically “cold” tumors. Medicenna's IL-4 Empowered Superkine, MDNA55, has been studied in 5 clinical trials including a Phase 2b trial for recurrent GBM, the most common and uniformly fatal form of brain cancer. MDNA55 has obtained Fast-Track and Orphan Drug status from the FDA and FDA/EMA, respectively.
