News Summary

Recent advancements in mesothelioma treatment show promise with PORT-7, a new drug by Portage Biotech. This selective adenosine A2B receptor inhibitor demonstrates superior efficacy over existing therapies and could revolutionize how this aggressive cancer is treated. Preclinical results were highlighted during a presentation at the AACR Annual Meeting, showcasing its potential in combination with other treatments. As research progresses, there is hope for a future where mesothelioma treatment is significantly improved, offering new life to patients.

PORT-7 Emerges as a New Hope Against Mesothelioma

In the ongoing battle against mesothelioma, a rare and aggressive cancer primarily caused by asbestos exposure, promising new advancements have been reported that may change the treatment landscape for patients. The focus is on Portage Biotech Inc. and its breakthrough drug, PORT-7 (TT-4), a selective adenosine A2B receptor inhibitor. Significant preclinical findings were unveiled, showcasing PORT-7’s potential to outperform existing treatments for mesothelioma.

Presentation at the AACR Annual Meeting

The cutting-edge research unveiled in the preclinical trials will be presented by Dr. Luciano Mutti, a leading expert in the field from the University of L’Aquila, Italy. The presentation occurred at the esteemed American Association for Cancer Research® (AACR) Annual Meeting, held at the McCormick Place Convention Center in Chicago on April 28, 2025. This leading event attracts oncologists, researchers, and industry insiders focused on the latest advancements in cancer therapies, making it the perfect platform for such groundbreaking news.

Key Findings Reveal Superior Efficacy

In preclinical studies utilizing a murine model of mesothelioma, PORT-7 demonstrated an impressive single-agent activity that surpassed that of current standard therapies, specifically the anti-PD1 antibody. Most notably, when PORT-7 was combined with the anti-PD1 treatment, the results were astounding. This combination therapy not only outperformed each treatment individually but also indicated a significant enhancement of the immune response. Tumor analyses revealed the formation of tertiary lymphoid structures in treated mice, a clear marker of a burgeoning immune reaction that is critical in combating cancer.

A New Strategy to Tackle Immune Resistance

Mesothelioma is notorious for its immune resistance, presenting a challenge to effective treatment. PORT-7’s ability to stimulate immune response provides a beacon of hope for those grappling with this daunting diagnosis. As the research progresses, Portage Biotech is gearing up to transition PORT-7 into a first-in-human clinical trial, which signifies an important step toward real-world applications for cancer patients.

Integrating PORT-6 for Enhanced Outcomes

In a complementary development, Portage Biotech is advancing another promising compound, PORT-6, a potent and selective inhibitor targeting the A2A adenosine receptor. The ultimate goal is to co-administer PORT-6 alongside PORT-7 in an ongoing trial dubbed ADPORT-601. This pioneering approach marks a noteworthy milestone as it will be the first to combine two highly selective adenosine receptor antagonists, aiming to achieve a complete blockade of adenosine-induced immunosuppression within the tumor microenvironment.

Potential for Comprehensive Treatment Strategies

This dual-antagonist treatment strategy is designed to completely neutralize adenosine-mediated immune suppression, thereby amplifying anti-tumor responses and expanding the efficacy of immunotherapy in treating various solid tumors, including mesothelioma. If successful, these innovative treatments could revolutionize the current therapeutic approaches, offering new life and revitalized hope for countless patients diagnosed with this aggressive form of cancer.

Conclusion

As research continues and preparations for clinical trials intensify, Portage Biotech stands at the forefront of transforming how the medical community approaches the treatment of mesothelioma. The promise of PORT-7 and its synergistic relations with PORT-6 represent a significant leap forward in harnessing the immune system to combat one of the most tenacious cancers known to mankind. This advancing science could very well rewrite the future of mesothelioma treatment.
