CD20 Market Insights

• CD20 Inhibitors are monoclonal antibodies that specifically target the CD20 protein present on the surface of B cells, leading to their depletion through mechanisms such as antibody-dependent cellular cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), and direct apoptosis. This targeted action spares other immune cells, offering a more selective and effective therapeutic approach.
• CD20 inhibitors are primarily approved and used for the treatment of B-cell malignancies and autoimmune diseases such as non-Hodgkin lymphoma (NHL), multiple sclerosis (MS), rheumatoid arthritis (RA), and others.
• Upon approval in 1997, rituximab became the first anti-CD20 monoclonal antibody approved by the FDA for the treatment of NHL. Today, it is approved for mature B-cell acute leukemia (B-AL), chronic lymphocytic leukemia (CLL), rheumatoid arthritis (RA) in combination with methotrexate in adult patients with an inadequate response to one or more TNF antagonist therapies, granulomatosis with polyangiitis (GPA) and microscopic polyangiitis(MPA) in adults and pediatric patients aged 2 years and older (in combination with glucocorticoids), and moderate to severe pemphigus vulgaris (PV) in adult patients.
• More than 25 years post-approval, rituximab remains a blockbuster drug, generating total global sales of USD 1,694 million in 2024, including USD 1,034 million from the U.S., USD 184 million from Europe, USD 21 million from Japan, and USD 455 million from international markets.
• Several CD20-targeting mAbs are now available for the treatment of both indolent and aggressive forms of B-cell non-Hodgkin lymphoma (NHL) in the front line, at relapse, and as maintenance therapy.
• Currently, several monoclonal antibodies target CD20 receptors available to treat multiple sclerosis (MS), including ocrelizumab, ofatumumab, and ublituximab. These agents have shown robust efficacy in reducing clinical manifestations and MRI lesion activity, forming a cornerstone of highly effective disease-modifying treatments.
• Beyond traditional mAbs, advancements include antibody-drug conjugates (ADCs), bispecific antibodies (BsAbs), and chimeric antigen receptor-modified (CAR) T cells. ADCs combine the precision of antibodies with the cytotoxic potential of drugs, enhancing therapeutic efficacy. BsAbs, especially CD20xCD3 constructs, redirect cytotoxic T cells to eliminate cancer cells with improved precision and potency. CAR-T cells represent a highly personalized and promising strategy for treating hematologic malignancies.
• Moreover, several CD20 inhibitors are currently being evaluated in CD-20 Clinical Trials. One example is odronextamab (REGN1979), a hinge-stabilized, IgG4-based CD20xCD3 bispecific antibody designed with reduced effector function. It is under investigation for follicular lymphoma, B-cell non-Hodgkin lymphoma (B-NHL), and other B-cell malignancies, with anticipated FDA approval during the forecast period.
• In February 2025, Regeneron Pharmaceuticals announced that the FDA had accepted the Biologics License Application (BLA) for odronextamab for review for relapsed/refractory Follicular Lymphoma, with a decision expected by July 2025.
• In March 2025, the FDA accepted the supplemental Biologics License Application (sBLA) for GAZYVA (obinutuzumab) for lupus nephritis. This decision is based on positive Phase III REGENCY trial results, which showed that GAZYVA plus standard therapy significantly improved complete renal response (CRR) compared to standard therapy alone. FDA approval is expected by October 2025.

CD20 Inhibitors Market: Understanding and Treatment Algorithm

CD20 inhibitors are a class of therapeutic agents designed to target the CD20 protein, a non-glycosylated phosphoprotein predominantly expressed on the surface of B cells from the pre-B to mature stages. This 297-amino acid, four-transmembrane protein plays a crucial role in B cell proliferation and differentiation. CD20 is highly expressed in various B-cell malignancies, making it an attractive target for therapeutic intervention. The expression of CD20 is regulated by a complex network of epigenetic factors and transcription factors, including EZH2, HDAC1/2, NFκB, and FOXO1, among others. These factors influence the signaling propensity of the B cell receptor (BCR), thereby affecting CD20 expression and function. ​

Therapeutically, CD20 inhibitors, particularly monoclonal antibodies, have revolutionized the treatment of B-cell malignancies such as non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL). These antibodies can induce tumor cell death through several mechanisms: antibody-dependent cell-mediated cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), and direct induction of apoptosis. The first-generation anti-CD20 monoclonal antibody, rituximab, is a chimeric IgG1 antibody that has been widely used in clinical practice. Subsequent generations, such as ofatumumab (fully human IgG1) and obinutuzumab (humanized IgG1 with enhanced Fc glycosylation), have been developed to improve efficacy and reduce immunogenicity. These newer agents demonstrate enhanced ADCC and CDC activities, thereby offering more potent therapeutic options for patients with CD20-positive B-cell malignancies.

Targeting CD20 using monoclonal antibodies has proven to be an important therapeutic approach for the management of autoimmune disorders, such as RMS. BRIUMVI is uniquely designed to lack certain sugar molecules normally expressed on the antibody. Removal of these sugar molecules, allows for efficient B-cell depletion at low doses. BRIUMVI is indicated for the treatment of adults with relapsing forms of multiple sclerosis (RMS), including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. It is the first and only anti-CD20 monoclonal antibody approved in the United States and European Union for adult RRMS patients that can be administered in a one-hour infusion, twice a year, following the starting dose.

• OCREVUS (ocrelizumab): Genentech

OCREVUS is a CD20-directed cytolytic antibody indicated for the treatment of relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults with primary progressive MS, in adults. The precise mechanisms through which OCREVUS exerts its therapeutic clinical effects in relapsing multiple sclerosis and relapsing-remitting multiple sclerosis are not fully elucidated but are presumed to involve immunomodulation through selective binding to CD20-expressing B cells. Following cell surface binding to B lymphocytes, OCREVUS results in antibody-dependent cellular cytolysis and complement-mediated lysis.

OCREVUS received FDA approval on March 28, 2017, for the treatment of relapsing and primary progressive multiple sclerosis. This approval made it the first drug approved for primary progressive MS. OCREVUS ZUNOVO, a subcutaneous injection formulation of ocrelizumab, was approved in September 2024.

CD-20 Emerging Drugs

• CHO-HO1: CHO Pharma

CHO-H01 is the world’s first glycoengineered bio better antibody featuring a homogeneous, fully α2,6-sialylated biantennary glycan structure. According to the NIH, biobetters are newly developed drugs based on existing peptide or protein therapeutics, enhanced to improve characteristics such as target epitope affinity and selectivity, as well as resistance to degradation.

CHO-H01 is designed to target CD20, a protein found on the surface of B cells. It works mainly through several immune mechanisms: triggering cell killing by immune cells (ADCC), promoting immune cell engulfing of cancer cells (ADCP), activating the complement system to kill cells (CDC), and inducing cancer cell death (apoptosis). Compared to its original non-glycoengineered version, CHO-H01 binds more strongly to the FcγRIIIa receptor, shows 30–50 times higher ADCC activity, and is more effective at reducing tumor growth in preclinical studies. It also remains effective against B lymphoma cells that no longer respond to Rituximab.

CHO-H01 is currently in Phase I/IIa, recruiting subjects with refractory non-Hodgkin lymphoma (NHL).

• MB-106 : MustangBio

Mustang Bio, in partnership with Fred Hutch, is advancing MB-106, a CD20-targeted CAR T therapy, initially aimed at treating hematologic malignancies and now pivoting toward autoimmune diseases.  As of March 2025, 73 patients have been treated in ongoing Phase 1 CD-20 clinical trials, demonstrating a favorable safety profile and high response rates, including a 90% overall response rate in Waldenström macroglobulinemia. Despite these promising results, Mustang closed its own MB-106 trials in mid-2024 due to funding limitations. The clinical development of MB-106 will now focus solely on autoimmune indications, with a Phase I investigator-sponsored trial at Fred Hutch planned for initiation in late 2025. This strategic shift underscores a resource-driven realignment while maintaining development momentum in a promising therapeutic domain.
