Brief Summary:
This study is being done in patients who have been receiving corticosteroids or other immunosuppressive therapies for the treatment of cGVHD for at least 6 months. The purpose of this study is to find out if itacitinib in combination with corticosteroids or other immunosuppressive therapies is safe and effective in people with cGVHD.

Condition or disease Intervention/treatment Phase
Chronic Graft-versus-host-disease Drug: Itacitinib Phase 2

Detailed Description:
Graft versus host disease remains a major hurdle to improve allogeneic hematopoietic stem cell transplantation outcome, with cGVHD being associated with decreased quality of life. Suppression of the immune system with corticosteroids forms the basis of first-line therapy for management of GVHD, but sustained responses are usually seen in less than 50 percent of patients and there is no standard second- or third-line treatment for steroid refractory cGVHD. Identification of novel therapeutic targets are needed to improve outcomes. Therapeutic potential has been shown by a JAK inhibitor in the treatment of steroid refractory GVHD. Itacitinib is a novel, selective inhibitor of the JAK family of protein tyrosine kinases and will be studied here in patients with steroid refractory cGVHD.

Primary Outcome Measures :
  1. Overall response rate (ORR) [ Time Frame: Approximately 6 months after the beginning of study drug treatment ]
    Defined as the proportion of patients with a cGVHD response of complete response (CR) or partial response (PR) after 6 months of treatment as defined by National Institutes of Health Consensus Criteria

Secondary Outcome Measures :
  1. Number of patients that can withdraw or decrease steroids [ Time Frame: Steroid dose will be assessed prior to first dose of study treatment, throughout study treatment, and when study treatment ends (approximately 2 years) ]
    Ability to withdraw or decrease steroids to ˂0.5 mg/kg of methylprednisolone or equivalent

  2. Overall survival [ Time Frame: Survival will be assessed every 3 months for 1 year after last dose of study treatment ]
    Defined as the time from the first day of study drug administration to death on study

  3. Assessment of safety based on frequency of adverse events [ Time Frame: Safety will be assessed throughout study treatment until 30 days after the last dose of study treatment (approximately 2 years) ]
    Safety will be assessed in terms of adverse events

  4. Quality of life impact [ Time Frame: Quality of life will be assessed prior to the start of study treatment, at two timepoints while receiving study treatment, and when study treatment ends (approximately 2 years) ]
    Changes in symptom burden will be measured using the Lee Symptom Scale. Subscale scores and the summary score range from 0 to 100, with a higher score indicating worse symptoms.

  5. Number of patients with recurrence or progression of cGVHD [ Time Frame: cGVHD status will be assessed prior to the start of study treatment, throughout study treatment, and when study treatment ends (approximately 2 years) ]
    Patients will be assessed for severity of cGVHD using clinician- and patient-reported activity assessments and review of steroid dose

  6. Relapse rate of underlying malignancy [ Time Frame: Relapse of underlying malignancy will be assessed throughout study treatment, when study treatment ends, and every 3 months for 1 year after last dose of study treatment (approximately 3 years) ]
    Patients will be closely monitored for any evidence of underlying disease relapse or recurrence; Formal re-staging will be done at physician discretion

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Written informed consent signed by the patient or legal guardian prior to any study-related screening procedures
  2. Patients who have undergone allo-hematopoietic stem cell transplant(s) (HSCT) from any donor HLA type (related or unrelated donor with any degree of HLA matching) using any graft source (bone marrow, peripheral blood stem cells, or cord blood). Recipients of non-myeloablative, myeloablative, and reduced intensity conditions are eligible.
  3. Active, clinically diagnosed, moderate or severe cGVHD per NIH Consensus Criteria:

    • Moderate cGVHD: at least 1 organ (except lung) with a score of 2, ≥3 organs involved with a score of 1 in each organ, or lung score of 1
    • Severe cGVHD: at least 1 organ with a score of 3, or lung score of 2 or 3
  4. cGVHD must be refractory to steroids defined by at least one criteria:

    • Patient is refractory to glucocorticoid therapy at screening: ongoing treatment with prednisone equivalent ≥0.20 mg/kg/day x 4 weeks (wks) at screening and organ progression documented 4 wks after the initiation of this regimen
    • Patient is dependent on glucocorticoid therapy at screening: treatment with a prednisone equivalent mean dose ≥0.20 mg/kg/day received for 12 wks at screening
    • Patient is intolerant to glucocorticoids at screening: ongoing treatment with prednisone equivalent ≥0.20 mg/kg/day x 4 wks at screening and presence of at least one documented glucocorticoid toxicity
  5. Evidence of myeloid and platelet engraftment (absolute neutrophil count ˃1,000/mm^3 and platelet count ˃25,000/mm^3). Use of growth factors or platelet transfusions is not allowed within 7 days before screening of laboratory assessment.
  6. Patients must currently be receiving systemic or other immunosuppressive therapies for the treatment of cGVHD for a duration of ˃6 months prior to start of study treatment
  7. Patients must be able to swallow and retain oral medication
  8. Eastern Cooperative Oncology Group Performance Status score of 0, 1, or 2
  9. Adequate hematologic function

  11. Patients willing to avoid pregnancy or father children based on 1 of the following:

    • Women of non-childbearing potential (i.e., surgically sterile by hysterectomy and/or bilateral oophorectomy OR ≥12 months of amenorrhea)
    • Women of childbearing potential who have a negative serum pregnancy test at screening and who agree to take appropriate precautions to avoid pregnancy from screening through safety follow-up.

Exclusion Criteria:

  1. Receiving concomitant JAK inhibitor for cGVHD; prior treatment with a JAK inhibitor for acute GVHD is permitted if treatment was stopped more than 60 days prior to study start. Patients are eligible if JAK inhibitors for treatment of cGVHD are stopped due to side effects and not due to refractoriness.
  2. Treatment with any other investigational agent, device, or procedure, within 28 days (or 5 half-lives, whichever is longer) of enrollment. For previous study drugs where 5 half-lives is ≤28 days, a minimum of 10 days between termination of that study drug and administration of itacitinib is required.

    • Active uncontrolled bacterial, fungal, parasitic, or viral infection. Infections are considered controlled if appropriate therapy has been instituted and, at the time of screening, no signs of infection progression are present. Progression of infection is defined as hemodynamic instability attributable to sepsis, new symptoms, worsening physical signs or radiographic findings attributable to infection. Persisting fever without other signs or symptoms will not be interpreted as progressing infection.
