The inhibitory receptor PVRIG is dominantly expressed in the bone marrow of patients with multiple myeloma and its blockade enhances T-cell engager's immune activation.

Therapeutic advances in treating patients with multiple myeloma (MM), including novel immunotherapies, have improved the disease control, but it remains incurable. Although traditional immune check point inhibitors have shown limited clinical benefit, targeting alternative immune-inhibitory pathways may offer a novel way to address relapsed disease. Blockade of the immune regulator TIGIT was shown to enhance antitumor immunity in preclinical MM models.

Targeting B-cell maturation antigen for treatment and monitoring of relapsed/refractory multiple myeloma patients: a comprehensive review.

Despite major therapeutic advancements in recent years, multiple myeloma (MM) remains an incurable disease with nearly all patients experiencing relapsed and refractory disease over the course of treatment. Extending the duration and durability of clinical responses will necessitate the development of therapeutics with novel targets that are capable of robustly and specifically eliminating myeloma cells. B-cell maturation antigen (BCMA) is a membrane-bound protein expressed predominantly on malignant plasma cells and has recently been the target of several novel therapeutics to treat MM patients.

Serum B-Cell Maturation Antigen Reflects Disease Status in a Patient Who Developed Nonsecretory Multiple Myeloma: A Case Report.

Introduction: Multiple myeloma (MM) is an incurable bone marrow (BM)-based cancer involving clonal plasma cells. Most patients show elevated levels of serum monoclonal protein (sMP) and kappa or lambda serum free light chains (sFLCs) at diagnosis. However, around 1-2% of patients, termed nonsecretory, do not produce these biomarkers.

Preclinical and clinical evaluation of the Janus Kinase inhibitor ruxolitinib in multiple myeloma.

Multiple myeloma (MM) is the most common primary malignancy of the bone marrow. No established curative treatment is currently available for patients diagnosed with MM. In recent years, new and more effective drugs have become available for the treatment of this B-cell malignancy.
