Brief Summary:
A Phase IIa single arm open-label study to investigate the safety, tolerability, and PK of F-652 in combination with systemic corticosteroids in subjects who have undergone Hematopoietic Stem Cell Transplantation (HSCT) and have newly diagnosed grade II-IV lower GI acute Graft Verses Host Disease (aGVHD). Treatment with F-652 will be once a week for 4 weeks, with post treatment follow up visits on days 28, 56, 180 and 365.

Condition or disease Intervention/treatment Phase
Acute Graft vs Host Disease Drug: Recombinant Human Interleukin-22 IgG2-Fc (F-652) Drug: Systemic Corticosteroids Phase 1 Phase 2

Detailed Description:

This is a Phase IIa single arm open-label study to investigate the safety, tolerability, and PK of F-652 in combination with systemic corticosteroids in subjects who have undergone HSCT and have newly diagnosed grade II-IV lower GI aGVHD. The HSCT may be derived from bone marrow, peripheral blood stem cells, or cord blood. The PK of F-652 in this subject population will be investigated. Subjects may be replaced if subject withdrawal is not related to safety or treatment response.

F-652 will be administered in conjunction with prednisone (or equivalent) at the time of the onset of clinical symptoms consistent with GI and/or liver aGVHD. Prednisone (or equivalent) will be given at a dose of 2 mg/kg/day and tapered as per protocol.

F-652 will be administered intravenously at a rate of 100 mL/hour for one hour once per week for four weeks. A total of 4 doses will be administered at a dose of 45 μg/kg each. Subjects will be followed for safety and efficacy through Day 180, and subject survival status will be collected at Day 365.

In the first stage of the trial, a total of 16 subjects will be enrolled. If six or fewer have a Day 28 treatment response, the trial will close due to a lack of efficacy. If seven or more have a response, an additional 11 subjects will be enrolled into study for a total sample size of 27. During the course of a subject's therapy, dose reduction may occur on an individual basis as per protocol.

    The number of participants with Lower GI aGVHD treatment response at days 14 and 56 categorized by complete response (CR), very good partial response (VGPR), partial response (PR), no response (NR)/stable, and progression

  2. The Number of Participants With Overall aGVHD Treatment Response at Days 14, 28, and 56. [ Time Frame: Measured at day 14, 28 and 56 after initial dosing of F-652 ]
    The number of participants with overall aGVHD treatment response at Days 14, 28, and 56 categorized by complete response (CR), partial response (PR), no response (NR), and progression.

  3. The Number of Participants With Discontinuation of Immunosuppressive Medication at Day 180 and 1 Year Post Initial Dosing of F-652. [ Time Frame: Measured at Day 180 and 1 year after initial dosing of F-652. ]
    The number of participants with discontinuation of immunosuppressive medication at day 180 and one year post initial dose.

  4. The Number of Participants With Overall Survival at 1 Year After First Infusion of F-652. [ Time Frame: Measured 1 year after first infusion. ]

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Age ≥18 years and ≤80.
  2. Newly diagnosed lower GI grade II-IV aGVHD with clinical diagnosis based on modified Keystone criteria1 following allogeneic HSCT using bone marrow, peripheral blood stem cells, or cord blood. Grading of aGVHD will be based on International Bone Marrow Transplant Registry (IBMTR) criteria.
  3. Subjects are willing to undergo a biopsy to confirm lower GI aGVHD. Biopsy results are not needed to initiate treatment. However, if aGVHD is not confirmed histologically, treatment with F-652 will be discontinued.
  4. Female subjects of childbearing potential who agree to practice 2 effective methods of contraception.
  5. Male subjects, even if surgically sterilized (i.e. Status post-vasectomy) must agree to agree to practice contraception.
  6. Have adequate renal function (Serum creatinine <3 mg/dL).
  7. ANC >500/mm3.
  8. Show evidence of a personally signed and dated informed consent document indicating that the subject (or legally acceptable representative) has been informed of all pertinent aspects of the trial.

Exclusion Criteria:

Subjects who met any of the following criteria were excluded from the study:

  1. Evidence of relapse or progression of hematologic malignancy at the time of study enrollment.
  2. Active uncontrolled infection. Subjects with a controlled infection receiving definitive therapy for 48 hours prior to enrollment were eligible.
  3. Subjects requiring vasopressors or mechanical ventilation.
  4. Subjects who had received previous systemic corticosteroids for the treatment of acute GI GVHD for longer than 5 days. Subjects who were treated with systemic corticosteroids for aGVHD for a prior allogeneic HSCT >12 months ago were eligible.

  15. Cytotoxic, biologic, or investigational agents were not permitted throughout the study. These included, but were not limited to, ATG, alemtuzumab, rituximab, photopheresis, and thalidomide. Subjects who participated in any other investigational drug trial or had exposure to any other investigational agent, device, or procedure, within 4 weeks prior to screening and throughout the entire trial, except for trials of investigational drugs administered prophylactically for GVHD or CMV post-allogeneic HSCT. In this exception, the other investigational drug must have been discontinued upon enrolling (i.e., screening/sign ICF) into this study.
