The Product

MyeliMMune™ — an allogeneic tumor antigen

An off-the-shelf, cell-based immunotherapy that presents a comprehensive antigenic blueprint of multiple myeloma to the patient’s own immune system — built from two human myeloma cell lines together with GM-CSF–secreting cells that act as a built-in immune adjuvant.

Off-the-shelf

HLA-agnostic and allogeneic — manufactured in advance, with no patient-specific tissue matching required.

Broad & multi-target

Presents a wide antigen array rather than a single marker, reducing the opportunity for tumor escape.

Durable by design

GM-CSF recruits antigen-presenting cells to generate long-lived, marrow-homing memory T cells.

Antigen Coverage
Lineage-specific surface antigens

BCMA · FGFR3 · SLAMF7

Cancer-testis antigens

MAGE-A3 · NY-ESO-1

Mutant protein drivers

TP53 · NRAS · BRAF

Mechanism of Action

From broad antigens to permanent immune surveillance

01

Present

A broad myeloma antigen array is delivered with a GM-CSF adjuvant.

02

Recruit

GM-CSF attracts antigen-presenting cells to prime the response.

03

Expand

De novo expansion of durable, marrow-homing memory T-cell clones.

04

Surveil

Permanent, multi-target surveillance that maintains remission.

Maintains remission rather than simply reducing tumor burden — while avoiding the toxicities of passive antibody therapies.

Clinical Development

A clear path from proof to approval

Phase 1 · Complete

Durable immunity, clean safety

Single-arm study at Johns Hopkins. No treatment-related dose-limiting toxicities; immune responses persisting up to 5–7 years; progression-free survival not reached at extended follow-up.

Phase 2 · Planned

SmoldeiMMune-1

A randomized Phase II study of MyeliMMune™ for smoldering myeloma patients.

Phase 3 · Planned

Confirmatory study

A randomized confirmatory trial to follow positive Phase II proof-of-concept, targeting FDA approval for this first-in-class therapy.

The Company

Intercepting myeloma before symptomatic disease takes hold

Meridian Therapeutics is a clinical-stage biopharmaceutical company developing immune-based therapies for hematologic malignancies, with an initial focus on multiple myeloma. We exclusively own the MyeliMMune™ intellectual property and existing cGMP-manufactured inventory, with a corporate IND in place.

Our mission

Intercept myeloma before symptomatic disease takes hold — using the durability of the immune system to maintain and extend the responses that conventional therapies achieve but rarely sustain.

Our vision

Intercept hematologic malignancies before symptomatic transition, applying the same active-immunity approach across blood cancers beyond multiple myeloma.
