NCT05704400 ↗ Efficacy of Anti-CD20 Ab Associated With Anti-CD38 in the Childhood Multidrug Dependent and Resistant Nephrotic Syndrome Not yet recruiting Istituto Giannina Gaslini Phase 2 2023-03-01 Nephrotic syndrome is considered a disease caused by an interplay of immunological stimuli with adaptive immunity(CD80/CD40) as trigger and Treg in the mid between co-stimulatory molecules and effectors. The positive effect of drugs blocking CD20 maturation in SDNS suggests a main role of these cells in regulating the system. Multidrug dependent, multidrug resistant nephrotic syndrome as well as post transplant FSGS recurrence patients can be considered difficult to treat patients and the association of two drugs, one targeting CD20 and a targeting plasmacells can be use in order to block the stimulatory cascade at more sites.

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00517530 ↗ A Dose-Escalating Study of Obinutuzumab in Patients With B-lymphocyte Antigen (CD20+) Malignant Disease (GAUGUIN) Completed Hoffmann-La Roche Phase 1/Phase 2 2007-09-01 The primary objective for the phase I part of the study is to investigate the safety and tolerability of escalating intravenous (IV) doses of obinutuzumab given as monotherapy in participants with CD20+ (tumor-infiltrating lymphocytic) Malignant Disease, including B-cell chronic lymphocytic leukemia (CLL) and Non-Hodgkin's Lymphoma (NHL). The primary objective for the phase II part of the study is to investigate the efficacy and safety of one dose of obinutuzumab in participants with relapsed/refractory CLL and NHL that is, in turn, either indolent (iNHL) or aggressive (aNHL). It is an open label dose escalating study in phase I and open label in phase II, but the two doses in iNHL & aNHL are randomized (to high or low dose of the same open label treatment). CLL was not randomized as only one dose level was used. Participants with a response who might gain additional benefit from being treated again in the opinion of the investigator may be enrolled in a Retreatment Period.
NCT00576758 ↗ GAUSS: A Study of Obinutuzumab (RO5072759) in Patients With Indolent Non-Hodgkin's Lymphoma Completed Hoffmann-La Roche Phase 2 2008-01-01 This study will investigate the efficacy of weekly intravenous obinutuzumab [GA101 (RO5072759)] monotherapy, in patients with relapsed CD20+ indolent Non-Hodgkin's Lymphoma. Patients will be randomized to receive either GA101 or rituximab, given as four weekly infusions. At the conclusion of the initial trial patients may be eligible to continue therapy up to 24 months. The anticipated time on study treatment is 3- 24 months, and the target sample size is 100-500 individuals.
NCT00825149 ↗ A Study of Obinutuzumab in Combination With Chemotherapy in Participants With CD20+ B-Cell Follicular Non-Hodgkin's Lymphoma Completed Hoffmann-La Roche Phase 1 2009-02-01 This open-label, randomized, phase Ib study will assess the safety and efficacy of obinutuzumab given in combination with FC (fludarabine and cyclophosphamide) or CHOP (cyclophosphamide, doxorubicin, vincristine and prednisolone) or bendamustine induction chemotherapy in participants with Cluster of Differentiation (CD) 20+ B-cell Follicular Lymphoma (FL). Participants with complete response or partial response after induction therapy may receive maintenance therapy every 3 months for 2 years or until disease progression, whichever comes first. All participants in the induction period of the study will have a safety follow-up visit 28 days after completing the last dose of obinutuzumab + chemotherapy, and will be followed for at least 2 years, unless they are being treated in maintenance or discontinue from the study prior to this time point. Participants who complete/discontinue maintenance therapy will also be followed for a period of 2 years after receiving the last dose of obinutuzumab or until progression/new antilymphoma treatment.
NCT01010061 ↗ CLL11: A Study of Obinutuzumab (RO5072759 [GA101]) With Chlorambucil in Patients With Previously Untreated Chronic Lymphocytic Leukemia (Stage 1a) Completed Genentech, Inc. Phase 3 2009-12-21 This open-label, randomized, 3-arm study will evaluate the efficacy and safety of obinutuzumab (RO5072759) in combination with chlorambucil as compared to rituximab plus chlorambucil or chlorambucil alone in patients with previously untreated chronic lymphocytic leukemia (CLL).

Obinutuzumab Market Analysis and Financial Projection

Last updated: February 4, 2026

What is the status of clinical trials for obinutuzumab?

Obinutuzumab, marketed as Gazyva by Roche, is a monoclonal antibody targeting CD20-positive B cells. It is approved for use in chronic lymphocytic leukemia (CLL) and follicular lymphoma (FL). The drug has undergone multiple phases of clinical trials to evaluate its efficacy across various hematologic malignancies.

Ongoing and Completed Clinical Trials

  • Phase 3 Trials:

    • CLL: The CLL14 trial compared obinutuzumab plus chlorambucil against chlorambucil alone. Results published in 2019 showed improved progression-free survival (PFS) 29.2 months versus 15.2 months (hazard ratio: 0.35; p < 0.001) [1].
    • Follicular Lymphoma (FL): The GALLIUM trial evaluated obinutuzumab versus rituximab plus chemotherapy, demonstrating superior PFS at 45.0 months (HR: 0.66; p = 0.001) in favor of obinutuzumab [2].
  • Phase 1/2 Trials:

    • Trials investigating obinutuzumab in combination with novel agents such as venetoclax and ibrutinib remain active, targeting relapsed/refractory B-cell lymphomas.
  • Regulatory Submissions:

    • Roche has submitted supplemental indications based on emerging data. For example, new potential uses in marginal zone lymphoma (MZL) are under review, with trial data pending.

Trial Completion Dates and Status

Most pivotal phase 3 trials concluded between 2018 and 2021. Registration databases show ongoing trials include:

  • A phase 2 study (NCT04549751) evaluating obinutuzumab with venetoclax in CLL, expected completion in Q2 2023.
  • An extension study in follicular lymphoma (NCT01861091) continues follow-up for long-term safety and efficacy.

Total active or recruiting trials stands at approximately 20, primarily registered on ClinicalTrials.gov, with a focus on B-cell malignancies and combination therapies.

How does obinutuzumab fit within the market for B-cell lymphoma treatments?

Market Size and Historical Data

The global B-cell non-Hodgkin lymphoma (NHL) therapeutics market was valued at approximately $8.4 billion in 2022, projected to reach $13.2 billion by 2030, expanding at a compound annual growth rate (CAGR) of around 5.8%. Obinutuzumab constitutes a significant segment within this landscape, directly competing with rituximab and ofatumumab.

Competitive Landscape

  • Key Competitors:

    • Rituximab: Estimated 60% market share within anti-CD20 therapies before biosimilars entered.
    • Obinutuzumab: Gained market share post-approval in 2014 for CLL and 2017 for FL.
    • Ofatumumab: Marketed for CLL and multiple sclerosis.
  • Market Penetration:

    • In 2022, obinutuzumab captured approximately 15% of first-line B-cell lymphoma therapy sales, with growth driven by data from GALLIUM and CLL14 trials.

Pricing and Reimbursement

  • The wholesale acquisition cost (WAC) in the U.S. is approximately $7,000 per 100 mg vial and $26,000 for a 1000 mg vial. Total treatment courses vary but typically reach $50,000–$70,000.
  • Coverage is generally favorable due to demonstrated clinical benefits, but reimbursement varies by country and healthcare system.

Market Drivers and Barriers

  • Drivers include superior efficacy data over rituximab, increased adoption of combination regimens, and expansion into new indications.
  • Barriers include high costs, competition from biosimilars, and the potential for adverse effects such as infusion reactions and H пользовательsystem_Text_Pending
