Moderna Begins Clinical Trial of Novel mRNA-2808 T-Cell Engager for Multiple Myeloma
New Approach Targets Tumor Heterogeneity with Multiplexed Therapy
Moderna, Inc. has taken a notable step in cancer treatment by dosing the first patient in a Phase 1/2 clinical study of mRNA-2808, its investigational T-cell engager for relapsed or refractory multiple myeloma (RRMM). This trial, which marks Moderna’s entry into T-cell engager therapies, leverages their mRNA technology to simultaneously target three validated myeloma-associated antigens. The innovative multiplexed design aims to tackle tumor heterogeneity—one of the greatest hurdles in myeloma treatment—and combat the common challenge of target-mediated resistance.
Phase 1/2 Study Details and Patient Access
The clinical study (NCT07116616) is underway at SCRI Oncology Partners in Nashville, in partnership with the Sarah Cannon Research Institute. The initial phase focuses on dose escalation and evaluates safety and tolerability for patients aged 18 and older who have RRMM. By encoding three T-cell engagers into a single therapy, Moderna aims to increase the chances of effective tumor control where current therapies may fall short due to the cancer’s complex biology.
| Therapy | Study Phase | Targets | Study Population | Location |
|---|---|---|---|---|
| mRNA-2808 | Phase 1/2 (dose escalation) | 3 Myeloma-associated antigens | RRMM patients, age 18+ | SCRI Oncology Partners, Nashville, TN |
Multiplexed T-Cell Engagement: Potential to Address Resistance in Myeloma
The T-cell engager strategy behind mRNA-2808 sets it apart. Traditional single-target approaches often struggle with disease recurrence, as myeloma cells adapt and develop resistance. By contrast, mRNA-2808’s three-pronged antigen targeting seeks to improve efficacy and reduce escape pathways that commonly undermine treatment.
Dr. Kyle Holen, Head of Development, Oncology at Moderna, emphasized the therapy’s innovative profile: “Our mRNA platform uniquely allows for the multiplexing of several T-cell engager targets, designed to attack the disease from multiple angles.” This strategy may help fill a significant gap for patients who have exhausted other treatment options.
What Could This Mean for Multiple Myeloma Patients?
Multiple myeloma remains a particularly challenging cancer, with patients often relapsing despite available therapies. If mRNA-2808 shows promising safety and efficacy in the ongoing study, it could become a game changer for those who develop resistance to current regimens. As Dr. Hans Lee, Director of Myeloma Research at SCRI, notes: “mRNA-based therapies could change the way we think about treating cancers like multiple myeloma.”
Takeaway: A New Frontier in mRNA-Driven Cancer Therapy
While results are not yet available, the launch of Moderna’s Phase 1/2 trial with a multiplexed mRNA-based T-cell engager puts the spotlight on novel immuno-oncology approaches. Investors, clinicians, and patients will be closely watching how this platform performs—not just in myeloma, but as a proof-of-concept for mRNA-driven cancer medicines in broader indications.
As Moderna continues to diversify beyond infectious diseases, this trial serves as an early marker of how rapidly the field of mRNA therapeutics is advancing. It’s a story worth following for anyone interested in the next wave of precision cancer therapies.
