Marker Therapeutics - Our Science
Our Science
MultiTAA Technology

Marker’s Multi-Antigen Targeted (MultiTAA) technology utilizes a novel, non-genetically modified cell therapy approach that selectively expands tumor-specific T cells from a patient’s blood capable of recognizing a broad range of tumor antigens. In early clinical trials, the multi-antigen approach has been well-tolerated and shown to enhance tumor killing capability.

Targets Multiple
Tumor Antigens

Marker’s unique MultiTAA technology differs significantly from today’s leading cell therapies, which are genetically engineered to recognize a single portion (or epitope) of a single tumor-associated antigen. MultiTAA-specific T cells recognize up to six antigens for a potent, durable anti-tumor response.

Broad, Durable
Anti-Tumor Effect

MultiTAA-specific therapies consistently demonstrate epitope spreading – inducing the patient’s own T cells to expand, potentially contributing to a lasting anti-tumor effect.

Clinical
Safety

MultiTAA-specific T cell therapies have been well-tolerated in clinical trials to date and may have reduced toxicities compared to current engineered CAR-T and T cell receptor-based therapies.

Natural
T Cells

MultiTAA-specific T cell therapies, which are based on the selective expansion of a patient’s natural T cells and are not genetically engineered, carry no mutagenesis risk.

Improved
Manufacturing

MultiTAA-specific T cells are significantly less expensive to manufacture than genetically engineered T cells. The cell manufacturing process is efficient and scalable.

Outpatient
Administration

Unlike other cell therapies which require pre-conditioning regimens and hospitalization, MultiTAA-specific T cell therapies are designed to be administered in an outpatient setting.
