BioArctic and Mesenkia enter oncology research collaboration
Rhea-AI Summary
BioArctic (Nasdaq Stockholm: BIOA B) and Mesenkia Therapeutics have signed a research collaboration agreement to develop a novel antibody-based approach for glioblastoma, a highly aggressive brain cancer where delivery of large molecules to the brain is difficult.
The project will combine BioArctic's BrainTransporter™ technology with a Mesenkia KITAIbodies®-derived antibody targeting HVEM on glioblastoma tumor and tumor stem cells. BioArctic will generate the drug candidate, after which both parties plan preclinical studies to validate the concept and then decide on further steps. The collaboration is described as expanding BioArctic's BrainTransporter pipeline into oncology and leveraging Mesenkia's glioblastoma-focused antibody expertise.
Positive
- Signed research collaboration to combine BrainTransporter with Mesenkia’s KITAIbodies for glioblastoma
- Pipeline expansion as BrainTransporter platform moves beyond neurodegenerative diseases into oncology
Negative
- None.
AI-generated analysis. How Rhea-AI works. Not financial advice.
The collaboration combines BioArctic's proprietary BrainTransporter™ technology with an antibody, developed with Mesenkia's KITAIbodies® platform. The antibody targets HVEM[1], a protein found on the surface of certain glioblastoma tumor cells, including tumor stem cells. By addressing these cells, which are thought to contribute to tumor recurrence and treatment resistance, the project aims to unlock new treatment possibilities for patients with a very high unmet medical need.
Under the agreement, BioArctic will be responsible for generating a novel drug candidate by combining its BrainTransporter technology with Mesenkia's antibody. BioArctic and Mesenkia thereafter plan to perform preclinical studies to validate the concept and, based on the results of these studies, decide on next steps.
This research collaboration represents an important step in expanding BioArctic's BrainTransporter pipeline into oncology and further validates the platform's potential beyond neurodegenerative diseases. It also builds on BioArctic's core expertise in development and delivery of pharmaceuticals to the brain.
"We are excited to broaden our research and take a first step into oncology through this collaboration," said Gunilla Osswald, Chief Executive Officer of BioArctic. "Glioblastoma remains one of the most challenging cancers to treat, with limited therapeutic options and poor prognosis for those affected. By combining our BrainTransporter technology with Mesenkia's innovative antibody approach, we aim to target key disease-driving mechanisms to develop new ways to treat this devastating disease."
"This agreement marks an important step for Mesenkia and creates clear opportunities to explore a new treatment strategy for patients with glioblastoma together with BioArctic. The need for new treatments is substantial, particularly given the challenge of delivering medicines to tumor cells throughout the brain. By combining Mesenkia's antibody expertise with BioArctic's BrainTransporter technology, we can address one of the disease's key barriers in a new way. We look forward to advancing the concept together with BioArctic, with the long-term goal of enabling better treatment options for patients and their loved ones," said Moa Fransson, Chief Executive Officer of Mesenkia.

About BioArctic AB
BioArctic AB (publ) is a Swedish research-based biopharma company focusing on innovative treatments that can delay or stop the progression of neurodegenerative diseases. The company invented Leqembi® (lecanemab) – the world's first drug proven to slow the progression of the disease and reduce cognitive impairment in early Alzheimer's disease. Leqembi has been developed together with BioArctic's partner Eisai, who are responsible for regulatory interactions and commercialization globally. In addition to Leqembi, BioArctic has a broad research portfolio with antibodies against Parkinson's disease and ALS as well as additional projects against Alzheimer's disease. Several of the projects utilize the company's proprietary BrainTransporter™ technology, which has the potential to actively transport antibodies across the blood-brain barrier to enhance the efficacy of the treatment. BioArctic's B share (BIOA B) is listed on Nasdaq Stockholm Large Cap. For further information, please visit www.bioarctic.com.
