Myeloid Therapeutics Breaks New Ground with mRNA CAR Data

Myeloid Therapeutics Revolutionizes Cancer Treatment with New Data

– MT-302 and MT-303 introduce innovative in vivo mRNA CAR therapies –

– Translational results indicate potential in immune reprogramming and tumor infiltration –

Myeloid Therapeutics, Inc., a pioneering company in the realm of RNA therapeutic development, is set to present groundbreaking research on two key mRNA CAR therapies, MT-302 and MT-303, during an esteemed medical event. This announcement is poised to redefine standard treatments in cancer therapy by offering more effective and accessible options for patients.

At the upcoming annual meeting of the American Society of Clinical Oncology (ASCO), Myeloid is set to unveil vital insights regarding the design and early findings from clinical trials concerning its lead in vivo mRNA CAR therapies. These presentations are not just significant for the company but for the broader field of RNA-based immuno-oncology.

According to Daniel Getts, PhD, the CEO and Co-founder of Myeloid Therapeutics, “Our presentations at ASCO exhibit the successful application of our proprietary mRNA-LNP platform, which focuses on directly engineering immune cells in vivo.” He elaborated that MT-302 and MT-303 represent a move away from conventional CAR therapies by eliminating complex ex vivo processes, thereby delivering direct and targeted immune response in patients suffering from advanced solid tumors.

Matt Maurer, MD, Chief Medical Officer of Myeloid Therapeutics, echoed this sentiment, stating, “This research demonstrates our ability to administer multiple doses of LNP-mRNA effectively, enabling CAR-programmed myeloid cells to penetrate solid tumors and modify the tumor microenvironment, which is pivotal for future clinical applications.” He believes the preliminary results highlight the promise of Myeloid’s technological advancements and could potentially transform the approach to treating solid tumors.

Exploring MT-302: A Targeted Approach in Cancer Treatment

MT-302 stands out as the inaugural mRNA-based CAR therapy administrated intravenously to begin human clinical trials. This innovative solution employs synthetic mRNA encapsulated within lipid nanoparticles (LNPs) to effectively reprogram the patient’s circulating immune cells to exhibit a CAR targeting TROP2.

Key Findings of MT-302

• Immune Activation: Detailed single-cell RNA sequencing has revealed a selective expression of CAR in myeloid cells, coupled with an increase in pro-inflammatory gene activity across diverse tumor types.
• Target Engagement: Pharmacodynamic indicators confirm that the CAR was successfully delivered and expressed following systemic application.
• Continued Dose Escalation: Ongoing dose escalation is taking place with an optimized linear mRNA formulation, building upon preclinical data showing extended expression over 12 days.

Introducing MT-303: The Future of Hepatocellular Carcinoma Therapy

On the other hand, MT-303 represents an advanced mRNA CAR therapy tailored to reprogram specific myeloid cells to identify and eliminate GPC3+ tumor cells. This is achieved through intravenous administration of an LNP-mRNA construct.

MT-303 Clinical Trial Insights

• Design: A multicenter, open-label Phase 1 trial is underway for evaluating advanced solid tumors expressing GPC3. This trial utilizes a Bayesian Optimal Interval (BOIN) methodology for dose escalation.
• Mechanism: The therapy is driven by a GPC3-targeted CAR construct that is selectively expressed in myeloid cells, highlighting its innovative approach.

Myeloid Therapeutics intends to present further clinical data as the Phase 1 studies for MT-302 and MT-303 progress, offering hope for future advancements in cancer therapies.
