ORIGINAL: Medexus Demonstrates Cost-Effectiveness of Gleolan-Guided Surgery for High-Grade Glioma

ISPOR 2023 Presentation Shows 33% Lowered Costs with Gleolan Compared to Conventional White Light Surgery

2023-05-09 21:55 ET - News Release

Toronto, Ontario and Chicago, Illinois--(Newsfile Corp. - May 9, 2023) - Medexus Pharmaceuticals (TSX: MDP) (OTCQX: MEDXF) today presented data demonstrating a 33% cost savings with Gleolan® (aminolevulinic acid HCl) oral solution, compared to conventional white light surgery, in US patients with high-grade glioma. The data were presented at ISPOR 2023, the annual meeting of the Professional Society for Health Economics and Outcomes Research (formerly known as the International Society for Pharmacoeconomics and Outcomes Research) in Boston, Mass.

"These latest data reinforce that the efficiencies from Gleolan clearly justify the costs in all appropriate patients in whom imaging complete resection, or ICR, is a goal of surgery," commented study investigator Andrew E. Sloan, MD, a neurosurgeon at Piedmont Healthcare in Atlanta, Ga.

Use of Gleolan has been associated with improved imaging complete resection (ICR). In the pivotal trial leading to its approval, the ICR rate for Gleolan-guided surgery was 64%, compared to 38% for conventional white light surgery.*

"Although Gleolan is additive to the cost of surgery, its use results in lower cost per ICR, and therefore is a more efficient use of resources in the surgical resection of high-grade glioma," said Mark Fosdal, DHSc, PA-C, Director of Scientific Communications at Medexus.

The study presented at ISPOR 2023 compared the cost per ICR with Gleolan-guided surgery (in conjunction with blue light) to that of conventional white light surgery in patients with high-grade glioma. In reviewing data from facilities representing 80% of all Gleolan utilization in the United States, the investigators calculated an average adjusted total cost savings per ICR of US$38,292 for Gleolan-guided surgery when compared to conventional white light surgery.

About Gleolan®

Gleolan is the first and only optical imaging agent approved by the US Food and Drug Administration (FDA) for use in people with high-grade glioma (suspected World Health Organization [WHO] Grades III and IV on preoperative imaging) as an adjunct for the visualization of malignant tissue during surgery. Its active ingredient, aminolevulinic acid HCl (also known as 5-ALA), is a natural metabolite in the human body that is produced within the hemoglobin metabolic pathway.

When combined with white light and a blue filter, 5-ALA illuminates the brain tumor in a fluorescent pink color, allowing the neurosurgeon to see suspected malignant high-grade glioma tissue in real time. By providing the neurosurgeon with a better view of the surgical field, Gleolan facilitates a more precise and complete resection (removal) of the tumor.

NX Development Corp., the licensor of Medexus's commercialization rights to Gleolan in the United States, estimates that Gleolan has been used in more than 100,000 surgeries conducted in 42 countries worldwide. In pivotal studies in patients with suspected malignant high-grade glioma, use of Gleolan has been associated with decreased need for reoperation, no increased risk for long-term neurological complications, and reduced frequency and time to reintervention.**

Adverse reactions occurring in >1% of patients in the week following surgery were pyrexia, hypotension, nausea, and vomiting.
