Hemophagocytic Lymphohistiocytosis clinical trials at University of California Health

4 in progress, 2 open to eligible people

Showing trials for

  • PK and PD of Emapalumab in Children and Adults With MAS in Still's or SLE

    open to eligible people ages 6 months to 80 years

    The purpose of this study is to assess the safety, tolerability and efficacy of emapalumab in children and adults with macrophage activation syndrome (sHLH/MAS) in Still's disease (including systemic juvenile idiopathic arthritis and adult onset Still's disease) or with sHLH/MAS in systemic lupus erythematous, resenting an inadequate response to high dose glucocorticoid treatment.

  • Response-Adapted Ruxolitinib-Containing Regimen For The Treatment Of Hemophagocytic Lymphohistiocytosis

    open to eligible people ages up to 22 years

    This study is a multi-site Phase Ib/II, 2-arm non-randomized clinical trial to determine the efficacy and tolerability of a response-adapted regimen combining ruxolitinib, dexamethasone, and etoposide as Frontline therapy for patients with newly diagnosed hemophagocytic lymphohistiocytosis (HLH) or as Salvage therapy for patients with relapsed/refractory HLH. Primary Objective - To determine the efficacy and tolerability of a response-adapted ruxolitinib-containing regimen for patients with newly diagnosed HLH. Secondary Objectives - To describe the efficacy and tolerability of a response-adapted ruxolitinib-containing regimen for patients with relapsed/refractory HLH. - To describe the overall response and outcome for patients with newly diagnosed or relapsed/refractory HLH who are treated with this response-adapted ruxolitinib-containing regimen. Exploratory Objectives - To estimate the pharmacokinetic (PK) parameters of ruxolitinib, assess covariates of ruxolitinib pharmacokinetics, and test whether the drug's effectiveness is correlated with systemic drug exposure. - To query specific immunologic biomarkers and determine whether the levels of these biomarkers correlate with disease response and outcome.

  • ELA026 in Participants With Secondary Hemophagocytic Lymphohistiocytosis

    Sorry, not currently recruiting here

    Hemophagocytic lymphohistiocytosis is a rare, aggressive and life-threatening syndrome of excessive immune activation. ELA026 is a fully human IgG1 SIRP-directed monoclonal antibody designed to reduce the myeloid and T cells driving the inflammation. The purpose of this study is to assess the safety, efficacy pharmacokinetics and pharmacodynamics of ELA026 in participants with secondary hemophagocytic lymphohistiocytosis.

  • Ruxolitinib With De-Intensified HLH-94 for the Treatment of Hemophagocytic Lymphohistiocytosis (HLH)

    Sorry, not yet accepting patients

    This phase II trial tests the effects of ruxolitinib in combination with a de-intensified HLH-94 drug regimen has on patients with newly diagnosed hemophagocytic lymphohistiocytosis (HLH), a disorder caused by dysregulated immune responses (that is, immune responses that are too strong and cause inflammatory damage to normal tissues). The therapy used for HLH decreases the activity of the immune system. Ruxolitinib is a type of drug called a kinase inhibitor. It works by blocking the signals that cause inflammatory cells to multiply. De-intensified HLH-94 is a treatment regimen that includes 4 weeks of dexamethasone with the dose being decreased each week, and up to 4 weeks of etoposide. This combination is commonly used to treat HLH. Dexamethasone is a steroid medication that works by fighting inflammation. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and deoxyribonucleic acid (DNA) repair and may kill cancer cells and is used to kill the types of white blood cells in HLH that are attacking the body. Giving ruxolitinib in combination with a de-intensified HLH-94 drug regimen may reduce toxic exposure to therapy while maintaining efficacy in patients with HLH.
