Brief Summary:
An open-label, Phase II trial designed to assess the recommended phase 2 dose (RP2D) of itacitinib in combination ECP and efficacy of the combination after 24 weeks of therapy. The trial will consist of two parts: Part One will assess the RP2D. For dose-finding purposes, the DLT evaluation period will be defined as the time from the first dose of itacitinib lead-in (7-day lead-in) to the last day of cycle one combination therapy (Cycle one day 28). Part Two will further describe and characterize the safety and efficacy of the regimen. The RP2D will be determined by a 3+3 dose de-escalation design. Should dose level one be deemed intolerable, enrollment will proceed at dose level -1. The RP2D will be affirmed according to the rules of the 3+3 dose de-escalation scheme (Section 4.2). Once an RP2D has been confirmed, Part 2 will open as an expansion cohort.

Official Title: A Phase II Study of Itacitinib (INCB039110) and Extracorporeal Photopheresis (ECP) for First-Line Treatment in Chronic Graft Versus Host Disease
Actual Study Start Date : January 29, 2021
Estimated Primary Completion Date : October 2023
Estimated Study Completion Date : October 2025


Arm Intervention/treatment
Experimental: Treatment: all patients
Patients will self-administer itacitinib every morning regardless of food. ECP will be administered twice weekly on consecutive days for 8 weeks per institutional standards. At the end of 8 weeks of combination therapy, patients will start a standard ECP taper schedule and itacitinib will be continued at the assigned dose level. After six cycles of therapy, itacitinib may be tapered at the treating investigator's discretion as described below.
Drug: Itacitinib
All eligible patients will begin study therapy with approximately a week lead-in of itacitinib monotherapy at scheduled dose. Itacitinib will be taken daily at scheduled dose for a total of six cycles. itacitinib may be tapered as deemed appropriate by the treating investigator. Patients will remain on study therapy as long as treatment discontinuation criteria are not met.

Device: Extracorporeal Photopheresis (ECP)
ECP will begin after itacitinib lead in period. ECP will be administered twice weekly on consecutive days for 8 weeks per institutional standards. At the end of 8 weeks of combination therapy, patients will start a standard ECP taper schedule.

    • Hepatic:

      • Total bilirubin ≤ 2 mg/dL
      • AST(SGOT)/ALT(SGPT) ≤ 2.5 × institutional ULN (unless of non-hepatic origin). AST/ALT ≤ 5 x ULN is acceptable if associated with chronic GVHD.

    • Coagulation:

      • PT/INR < 1.5 x ULN and PTT (aPTT) < 1.5 x ULN (unless abnormalities are unrelated to coagulopathy or bleeding disorder). When treated with warfarin or other vitamin K antagonist, then INR ≤ 3 x ULN.

    • Woman of childbearing potential who has a negative serum pregnancy test at screening and negative urinary test before the first dose on Day 1 and who agrees to take appropriate precautions to avoid pregnancy (with at least 99% certainty) from screening through safety follow-up. Permitted methods that are at least 99% effective in preventing pregnancy should be communicated to the subject and their understanding confirmed.
    • Men who agree to take appropriate precautions to avoid fathering children (with at least 99% certainty) from screening through safety follow-up. Permitted methods that are at least 99% effective in preventing pregnancy should be communicated to the subject and their understanding confirmed.

  • Participants have uncontrolled manifestations of acute GVHD.
  • Treatment with any investigational medication within ≤ 30 days or 5 half-lives, whichever is longer, before the first dose of study drug.
  • Patients who have received any previous systemic treatment for chronic GVHD, including corticosteroids, prior to Cycle 1, Day 1.

Note: Prior and concomitant use of Calcineurin-Inhibitors (CNIs) for prevention and treatment of acute GVHD, as well as topical/inhaled steroids, is acceptable.

  • Received prior JAK inhibitor therapy for any indication ≤ 4 weeks prior to Cycle 1 Day 1.
  • Patients with relapsed or progressive malignant disease or any post-transplant lymphoproliferative disease.
  • Chronic GVHD occurring after a non-scheduled donor lymphocyte infusion (DLI) administered for pre-emptive treatment of malignancy recurrence. Participants who have received a scheduled DLI as part of their transplant procedure and not for management of malignancy relapse are eligible.

  • Pregnant or currently breast-feeding. Note: INCB039110 is a JAK1 inhibitor with the potential for serious or life-threatening birth defects or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with INCB039110, breastfeeding should be discontinued if the mother is treated with INCB039110. These potential risks may also apply to other agents used in this study.
  • Vaccinated with live, attenuated vaccines within 4 weeks of the first dose of study drug and while on trial.
  • Use of any prohibited concomitant medications as described in Section 6.5. A washout period of prohibited medications for a period of at least 5 half-lives or as clinically indicated should occur prior to the start of treatment.

  • History of other malignancy (not including the underlying malignancy that was the indication for the transplant), with the following exceptions:

    • Malignancy treated with curative intent and with no evidence of active disease present for more than 3 years prior to Screening and felt to be at low risk for recurrence by the treating physician.
    • Adequately treated non-melanomatous skin cancer or lentigo maligna melanoma without current evidence of disease.
    • Adequately treated cervical carcinoma in situ without current evidence of disease.
  • The subject has uncontrolled, significant intercurrent or recent illness including, but not limited to, the following conditions:

    • A clinically significant respiratory disease that requires mechanical ventilation support or ≥ 50% oxygen.
    • Any uncontrolled active systemic infection or active infection requiring systemic treatment that was ongoing ≤ 7 days before screening. Subjects with acute infections requiring treatment should delay screening/enrollment until the course of therapy has been completed and the event is considered resolved. Prophylactic antibiotics will be permitted.
    • Cholestatic disorders, or unresolved sinusoidal obstructive syndrome/ veno-occlusive disease of the liver (defined as persistent total bilirubin > 2 mg/dL, or abnormalities not attributable to GVHD and ongoing organ dysfunction).
  • History of thromboembolic event within 1 month before study registration.
  • HIV-infected patients on effective antiretroviral therapy with an undetectable viral load within 6 months are eligible for this trial.
  • Active HBV or HCV infection that requires treatment, or at risk for HBV reactivation (i.e., positive HBsAg). Participants with negative HBsAg and positive total HBc antibody may be included if HBV DNA is undetectable at the time of screening. Participants who are positive for HCV antibodies are eligible only if PCR is negative for HCV RNA. Participants whose immune status is unknown or uncertain must have results confirming immune status before enrollment. Serology results performed less than or equal to 6 months prior to the first planned dose of itacitinib are acceptable for determining eligibility.
