CD38 Inhibitors Market: Understanding and Treatment Algorithm

CD38 inhibitors represent a promising and rapidly evolving area in immunotherapy. CD38 is a multifunctional transmembrane glycoprotein with both receptor and enzymatic functions, playing a central role in calcium signaling, immune cell regulation, and cellular metabolism. It is highly expressed over a variety of immune cells, especially plasma cells, and is markedly upregulated in several pathological conditions, including hematologic malignancies, autoimmune diseases, and inflammatory disorders. This makes CD38 an attractive and versatile therapeutic target. Inhibition of CD38 can modulate immune responses, deplete pathogenic cell populations, and restore immune balance—opening new avenues for treating diseases beyond cancer.

While CD38-targeting monoclonal antibodies like DARZALEX and SARCLISA have already transformed the treatment landscape for multiple myeloma, ongoing research is expanding their application to conditions such as systemic lupus erythematosus, antibody-mediated rejection in organ transplantation, and other immune-driven diseases. With a growing pipeline of next-generation inhibitors, CD38-targeted therapies hold vast potential in precision medicine.

CD38 inhibitor Treatment

CD38 inhibitors have emerged as powerful agents in the treatment of a range of immune-mediated and malignant diseases. CD38, a multifunctional glycoprotein expressed over plasma cells, natural killer (NK) cells, and other immune cells, plays a central role in calcium signaling, cell adhesion, and immunoregulation. Its overexpression in pathological conditions such as multiple myeloma, autoimmune diseases, and transplant rejection makes it an attractive therapeutic target.

Monoclonal antibodies targeting CD38 have shown the ability to deplete pathogenic plasma cells and modulate immune responses effectively. DARZALEX (Daratumumab), the first approved anti-CD38 therapy, has significantly improved survival outcomes in multiple myeloma and demonstrated potential in autoimmune diseases like systemic lupus erythematosus (SLE) by reducing autoantibody-producing plasma cells. It has also shown benefit in managing antibody-mediated rejection (AMR) in organ transplantation, where conventional therapies often fail.

DARZALEX is approved for use in adult patients with multiple myeloma both as monotherapy and in various combination regimens. It can be used alone in patients who have received at least three prior lines of therapy, including a proteasome inhibitor and an immunomodulatory agent, or who are double-refractory to both. In combination therapy, DARZALEX is approved with several backbones depending on the treatment setting, including lenalidomide and dexamethasone, bortezomib-based regimens, carfilzomib and dexamethasone, and pomalidomide and dexamethasone. These combinations are indicated across newly diagnosed, transplant-eligible, and -ineligible, and relapsed or refractory patient populations, offering flexible treatment options across different stages of disease.

CD38 Inhibitor Marketed Drugs

• DARZALEX (daratumumab): Janssen Pharmaceutical

DARZALEX (daratumumab) is a first-in-class CD38-directed monoclonal antibody used in the treatment of multiple myeloma. CD38 is a surface protein highly expressed over myeloma cells, and daratumumab works by targeting and eliminating these malignant cells through multiple mechanisms, including antibody-dependent cellular cytotoxicity, complement-dependent cytotoxicity, and apoptosis. It also modulates the immune system by depleting immunosuppressive cells.

DARZALEX was first approved by the U.S. Food and Drug Administration (FDA) in November 2015 as a monotherapy for patients with multiple myeloma who had received at least three prior lines of therapy, including a proteasome inhibitor and an immunomodulatory agent, or who were double-refractory to both. This marked a significant advancement in multiple myeloma treatment, offering a novel therapeutic mechanism and improving outcomes for heavily pretreated patients. Further, it got EMEA approval in April 2017 and PMDA approval in September 2017. 

Since its initial approval, DARZALEX has gained several expanded indications and is now used widely in combination regimens across various stages of multiple myeloma, from newly diagnosed to relapsed or refractory cases.

• SARCLISA (Isatuximab): Sanofi  

SARCLISA (isatuximab-irfc) is a CD38-directed monoclonal antibody developed for the treatment of multiple myeloma. Like daratumumab, it targets the CD38 antigen highly expressed on the surface of myeloma cells, promoting their destruction through immune-mediated mechanisms such as antibody-dependent cellular cytotoxicity and complement activation. Additionally, it may induce direct apoptosis in tumor cells independent of immune effector functions.

SARCLISA received its initial U.S. FDA approval in March 2020 for use in combination with pomalidomide and dexamethasone in adult patients with relapsed or refractory multiple myeloma who had received at least two prior therapies, including both lenalidomide and a proteasome inhibitor. This approval offered a new therapeutic option for patients with difficult-to-treat disease.

Since then, its indications have expanded. Most notably, in September 2024, SARCLISA became the first FDA-approved CD38 therapy in combination with standard of care i.e. bortezomib, lenalidomide, and dexamethasone (VRd) for adults with newly diagnosed multiple myeloma who are not eligible for autologous stem cell transplant (ASCT). It is also approved in combination with carfilzomib and dexamethasone for patients with relapsed or refractory disease who have received one to three prior lines of therapy. These approvals mark SARCLISA as a growing force in the treatment landscape of multiple myeloma, especially for patients who may not be candidates for transplant or who have relapsed following standard regimens.
