Phase II Study of Tocilizumab for Patients With Glucocorticoid-refractory Acute GVHD After Allogeneic Hematopoetic Stem Cell Transplant (HSCT)

Tocilizumab (an Anti-human IL-6 Receptor Monoclonal Antibody) as a First Line Therapy for Patients With Glucocorticoid-refractory Acute Graft vs. Host Disease (aGVHD) After Allogeneic Hematopoetic Stem Cell Transplant (HSCT), a Phase II Study.

The purpose of this study is to determine if Tocilizumab is a safe and effective treatment for steroid-refractory acute graft versus host disease.

Study Overview

• Status: Terminated
• Conditions: Glucocorticosteroid Refractory Acute GVHD
• Intervention / Treatment: Drug: Toclizumab

Detailed Description

This clinical trial is testing a drug called Tocilizumab (a monoclonal antibody) as a first line therapy for subjects with steroid-refractory acute graft versus host disease (acute GVHD) after undergoing a bone marrow transplant. The purpose of the study is to test the safety and efficacy of Tocilizumab at differing dose schedules. There are 2 phases to this study. Both phases include subjects with acute GVHD have not responded to steroid treatment. Subjects enrolled in Phase IIp will receive Tocilizumab 8 mg/kg every week or every 2 weeks. Subjects enrolled in Phase II will receive one of two dose schedules determined by the results of Phase IIp. Depending on the dose they are assigned to, subjects will receive Tocilizumab every week or every 2 weeks for a total of 8 doses. The study medication may be interrupted, withheld or stopped for different reasons. However, subjects will be asked to follow up periodically for one year after starting Tocilizumab treatment.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years to 80 years (ADULT, OLDER_ADULT)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• Men or women ≥ 18 and ≤ 80 years of age
• Karnofsky Performance Status Scale ≥ 50%
• Glucocorticosteroid refractory acute GVHD Grade 2-4 by the Glucksberg functional classification.
• Patients who had experienced aGVHD grade 2-4 and responded to glucocorticosteroids in the past then had a flare of aGVHD requiring increasing immune suppression to 1 mg/kg of prednisone or equivalent are eligible for this study if they are refractory to steroids and provided that they did not receive a second line therapy for aGVHD in the past.

• Glucocorticosteroid refractory GVHD is defined as the following:

  • No response to corticosteroid therapy at ≥ 1.0 mg/kg methylprednisolone or equivalent after the onset of acute GVHD for a minimum of 3 and a maximum of 7 days OR
  • Progression of at least 1 overall grade within 3 days of glucocorticosteroid use OR
  • Incomplete response by 14 days of glucocorticosteroid use
• Ability to comply with planned procedures
• Ability to understand the information provided and to provide written evidence of informed consent
• Willingness of females of childbearing potential to use adequate contraception.
• Post-menopausal for at least 1 year or surgical sterilization or hysterectomy at least 3 months prior to screening

Exclusion Criteria:

• Subjects with only grade 1 acute GVHD
• Concurrent medical condition or disease that may interfere with clinical trial participation
• Relapsed or persistent malignancy.
• Receiving other drugs for the treatment of glucocorticosteroid refractory GVHD.
• Severe hepatic veno-occlusive disease or sinusoidal obstruction syndrome.
• History of hypersensitivity or severe allergic reactions to humanized or murine monoclonal antibodies
• Receipt of any experimental, unregistered therapy within or outside a clinical trial within 30 days or 5 plasma half-lives (whichever is shorter) before dosing
• Planned or current participation in any other clinical trial for treatment of GVHD during this clinical trial. Subjects are permitted on this trial if 30 days (or 5 half-lives) have passed since enrollment on other investigational drugs. If a subject develops another condition, he/she is permitted on other clinical trials to treat that condition. Subjects are not permitted to go on other clinical trials for steroid refractory acute GVHD. Subjects are permitted to participate in trials for chronic GVHD.
• Pregnancy (a negative serum or urine pregnancy test should be performed for all women of childbearing potential within 7 days of treatment) or lactation.
• Pre-existing or recent onset of demyelinating disorders
• Pre-existing or recent onset of gastrointestinal perforation
• Treatment with any investigational agent within 4 weeks of screening or 5 half-lives of the investigational drug (whichever is longer)
• Receipt of a live vaccine within 4 weeks prior to first infusion
• Previous treatment with Natalizumab (Tysabri®)
• History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies
• Known active UNCONTROLLED bacterial, viral, fungal, mycobacterial, or other infection (including tuberculosis or atypical mycobacterial disease, but excluding fungal infections of nail beds).
• Concomitant malignancies.
• History of psychiatric disorder that would interfere with normal participation in this protocol
• Significant cardiac or pulmonary disease (including obstructive pulmonary disease)
• ANC < 0.5 x 103
• History of drug, alcohol, or chemical abuse within 6 months prior to screening
• Serum creatinine > 1.9 mg/dL (168 µmol/L). Patients with serum creatinine values exceeding limits may be eligible for the study if their estimated glomerular filtration rates (GFR) are >30
• Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 3 times upper limit of normal (ULN) unless liver GVHD is suspected
• Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that may affect the interpretation of the results or render the patient at high risk from treatment complications

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Subjects With GVHD Who Are Tolerable to Tocilizumab After Having Failed Response to Glucocorticosteroid Treatment	Both subjects enrolled on this study experienced failed response to glucocorticosteroid treatment but were able to tolerate tocilizumab. We were unable to collect extensive data on these 2 subjects because they both died early on in the study due to disease complications.	Day 28

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Disease-free Overall Survival at 100 Days, 6 Months and One Year From the Time of the First Tocilizumab Infusion.	We were unable to evaluate disease-free survival at 100 days, 6 months and one year from the time of the first tocilizumab infusion. All subjects enrolled on this study died before this time point and the study closed to enrollment due to slow accrual.	Approximately 1 year
Toclizumab Response in Each Organ	We were unable to assess the Tocilizumab response in each organ at 1 year. All subjects enrolled on this study died before this time point and the study closed to enrollment due to slow accrual.	1 year
Effect of Toclizumab on Karnofsky Performance Status	We were unable to evaluate the effect of tocilizumab on Karnofsky Performance Status at 1 year. All subjects enrolled on this study died before this time point and the study closed to enrollment due to slow accrual.	1 year
