January 4, 2021 updated by: University of Michigan Rogel Cancer Center

Pilot Study of Ruxolitinib in Secondary Hemophagocytic Syndrome

This is a pilot study to determine the efficacy of Ruxolitinib in secondary hemophagocytic syndrome. The primary objective is to assess the efficacy of ruxolitinib 15 mg PO twice daily in patients with HPS. The primary endpoint is overall survival at two months.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Hemophagocytic Syndrome (HPS) is a disorder characterized by pathological activation of the immune system resulting in a systemic disorder characterized by excessive cytokine production and macrophage activation, culminating in cytopenias and evidence of hemophagocytosis on tissue specimens. The disorder can be sporadic or familial due to one of several mutations and is primarily seen in the pediatric population, with a reported incidence of 1 case per 3000 admissions. The actual incidence in adults is unknown and can be rarely sporadic, or secondary to viral infections, malignancy, or autoimmune disease.

HPS is a universally fatal disease if untreated. In adults, the median survival has been reported to be less than 2 months if diagnosis and treatment is delayed. Adult patients are treated with pediatric protocols with early institution of etoposide and steroids and consolidation with allogeneic stem cell transplant in appropriately selected patients if a familial form is identified. Other treatment strategies have been attempted, including rituximab, infliximab, entaracept, tocilizumab, and alemtuzumab. These anecdotal reports highlight the therapeutic potential of cytokine-targeted therapies in this disorder.

This is a pilot study to determine the efficacy of Ruxolitinib in secondary hemophagocytic syndrome. The primary objective is to assess the efficacy of ruxolitinib 15 mg PO twice daily in patients with HPS. The primary endpoint is overall survival at two months.

Patients will receive Ruxolitinib at 15 mg twice daily orally either on an empty stomach or with food for 4 weeks (28 days) in a 4 week (28 day) cycle. Ruxolitinib will be administered in continuous 28-day cycles.

In the absence of treatment delays or cessation due to adverse events, treatment may continue indefinitely or until one of the following criteria applies:

  • Disease progression.
  • Intercurrent illness that prevents further administration of treatment.
  • The investigator considers it, for safety reasons, to be in the best interest of the patient.
  • Unacceptable adverse events such as any toxicity or other issue that causes a delay of study drug administration by more than 4 weeks.
  • General or specific changes in the patient's condition render the patient unacceptable for further treatment in the judgment of the investigator.
  • Patient decision to withdraw from treatment (partial consent) or from the study (full consent.
  • Death.

Patients will be followed for toxicity for 30 days after treatment has been discontinued or until death, whichever occurs first.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients, or their legally authorized representative, must voluntarily provide written IRB-approved informed consent.
  • Males and females, 18 years of age or older at the time of enrollment.
  • Patients must meet the diagnostic criteria for HPS (at least 5 of the following): fever, splenomegaly, cytopenia involving ≥2 cell lines (Hemoglobin <9 g/dL; platelets <100,000/μL; absolute neutrophil count <1000/μL), hypertriglyceridemia or hypofibrinogenemia, tissue demonstration of hemophagocytosis, low or absent NK (Natural Killer) cell activity, serum ferritin ≥3000 ug/L, soluble IL-2 receptor (CD25) >2400 U/mL.
  • In the investigator's opinion, the patient has the ability to participate fully in the study, and comply with all its requirements.

Exclusion Criteria:

  • CNS (Central Nervous System) involvement
  • Malabsorption
  • Known secondary HPS (Hemophagocytic Syndrome) that is otherwise treatable (e.g. non-Hodgkin's lymphoma).
  • Pregnant or lactating female: all females of child-bearing potential must have a negative serum pregnancy test within 7 days of treatment; lactating females must discontinue breast feeding.
  • Estimated creatinine clearance <15mL/min
  • Has received any prior systemic therapy, excluding corticosteroids, within 7 days (or 5 half-lives) of treatment.
  • No active malignancy at the time of enrollment, except nonmelanoma skin cancers or carcinoma in situ. Patients with a prior history of malignancy are eligible if their malignancy has been definitely treated or is in remission and does not require ongoing adjuvant or cancer-directed therapies.
  • Active hepatitis B or hepatitis C or known HIV infection
  • Known (and biopsy-confirmed) liver cirrhosis; or, a reported history of liver cirrhosis with a Model for End-stage Liver Disease (MELD) score >20.
