Medicenna's MDNA55 Data From Mid-Stage Brain Cancer Study Published In Peer-Reviewed Clinical Cancer Research
Medicenna Therapeutics Corp (NASDAQ: MDNA) announced the peer-reviewed publication of clinical data from its Phase 2b trial evaluating MDNA55 in recurrent glioblastoma (rGBM).
The Phase 2b trial evaluated MDNA55, an interleukin-4 (IL-4)-guided toxin, as a treatment for rGBM, the most common and uniformly fatal form of brain cancer.
Results show that the median overall survival (OS) was 11.8 months, which is longer than what would be expected from the approved drugs carmustine (OS of 5.1 – 7.5 months), lomustine (OS of 7.1 – 9.8 months), or temozolomide (OS of 5.4 – 9.9 months).
Notably, the data also shows a potential link between patients experiencing radiographic progression and those exhibiting insufficient MDNA55 penetration into the tumor, suggesting that at least a portion of patients who did not respond well to MDNA55 may have benefited from higher drug concentrations.
These analyses supplement previously presented findings observed in Medicenna's proposed patient population showing an 81% tumor control rate (26/32) and a median OS of 15.7 months, which represents a >100% improvement compared to an external control arm (median OS of 7.2 months).
Medicenna is currently pursuing a partnership strategy to facilitate MDNA55's further development through the planned Phase 3 clinical trial.
Price Action: MDNA shares are up 5.4% at $3.7 during the market trading hours on the last check Friday.
