Description

Summary

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.

Official Title

An Open-label, Single-arm, Multicenter Study to Evaluate the Safety, Efficacy and Pharmacokinetics of Multiple Doses of ELA026 in Participants With Secondary Hemophagocytic Lymphohistiocytosis (sHLH)

Details

This study is an open-label, single arm, multicenter interventional study, comprised of 4 cohorts; a dose escalating cohort (cohort 1) followed by 3 fixed dose cohorts (Cohorts 2-4). Newly diagnosed and previously treated participants with secondary hemophagocytic lymphohistiocytosis will be enrolled and treated over 12-weeks. Secondary hemophagocytic lymphohistiocytosis is the most common form of this disease and is typically associated with several other clinical conditions (eg, malignancy associated HLH (m-HLH), infection, or autoimmune disease).

Eligibility

You can join if…

Open to people ages 6 years and up

  1. ≥12 years at the time of HLH diagnosis (Cohort 1)
  2. ≥6 years at the time of HLH diagnosis (Cohort 2-4)
  3. Treatment naïve OR
  4. Early refractory sHLH
  5. Participant with sHLH confirmed criteria based on fulfilling 5 out of 8 HLH-2004 diagnostic criteria.

You CAN'T join if...

  1. Known or previous treatment for primary HLH
  2. Any other significant concurrent, uncontrolled medical condition that in the opinion of the Investigator contraindicates participation in this study
  3. Unknown trigger for sHLH
  4. Active, relapsed/refractory malignancy for which no suitable therapies are available to treat the malignancy triggering the HLH
  5. Allogeneic hemopoietic stem cell transplant (HSCT) within 100 days of the first dose of ELA026.
  6. Ongoing administration of any therapies used to treat HLH (excluding dexamethasone)
  7. Live or attenuated vaccine received within 6 weeks or bacille Calmette-Guerin (BCG) vaccine within 12 weeks prior to Screening
