Chronic Graft-versus-host-disease
Conditions
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 dose limiting toxicity (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. Once an RP2D has been confirmed, Part 2 will open as an expansion cohort. As this study was terminated after enrolling three patients out of an anticipated target accrual of 58, Part Two of this study did not occur.
Interventions
DRUGItacitinib
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. Patients with Partial Response (PR) or better may continue itacitinib for up to 1 year.
ECP will begin after itacitinib lead in period. At the end of 8 weeks of combination therapy, patients will start a standard ECP taper schedule. Patients achieving PR or better after 6 cycles of itacitinib may continue treatment with itacitinib for up to 1 year. Thereafter, itacitinib may be tapered at the treating investigator's discretion.

Count of Participants With Organ-specific Responses at 24 Weeks
Participants were assessed for chronic graft versus host disease (GVHD) severity per the NIH Consensus Development Project Criteria at baseline and after 24 weeks of treatment. The criteria evaluate 9 organ systems, and for each organ, defines changes in symptoms to qualify as a partial response (PR), complete response (CR), or progressive disease (PD) in that organ. In general, PR in an organ indicates partial improvement after prior involvement of that organ. CR indicates improvement to no symptoms after prior involvement. PD indicates worsening of symptoms in the organ system. Lack of response indicates that the organ system was involved at both baseline and 24 weeks, but did not improve or deteriorate sufficiently to qualify for PR, CR, or PD. No involvement/Not evaluable indicates that the organ system never had any GVHD symptoms or was not able to be evaluated.

Mean Clinician-evaluated GVHD Severity Score at 24 Weeks and 1 Year
Participants were assessed for chronic graft versus host disease (GVHD) severity per the NIH Consensus Development Project Criteria at baseline, after 24 weeks of treatment, and after one year of treatment. One data point in the criteria is a general rating the severity of the participant's GVHD symptoms, ranging from 0 (GVHD symptoms not at all severe) to 10 (most severe GVHD symptoms possible). The baseline severity score is reported in the baseline characteristics.
Time frame: at 24 weeks and 1 year
Population: Only one participant continued treatment long enough to be evaluated at 1 year.
| Arm | Measure | Group | Value (MEAN) | Dispersion |
|---|---|---|---|---|
| Treatment: All Participants | Mean Clinician-evaluated GVHD Severity Score at 24 Weeks and 1 Year | Severity score at 24 weeks | 4 score on a scale | Standard Deviation 1.73 |

|---|---|---|---|
| Treatment: All Participants | Mean Cumulative Prednisone Used up to 24 Weeks | 30 milligrams | Standard Deviation 42.426 |
Secondary
Mean NIH Global GVHD Score at 24 Weeks
Participants were assessed for chronic graft versus host disease (GVHD) severity per the NIH Consensus Development Project Criteria at baseline and after 24 weeks of treatment. One data point in the criteria is an overall global rating of the participant's GVHD, ranging from 0 (no GVHD) to 3 (severe GVHD). The baseline global score is reported in the baseline characteristics.
Time frame: 24 weeks
| Arm | Measure | Value (MEAN) | Dispersion |

| Treatment: All Participants | Mean NIH Global GVHD Score at 24 Weeks | 1.67 score on a scale | Standard Deviation 0.58 |
Secondary
Mean Participant-reported cGVHD Symptom Severity Score at 24 Weeks and at 1 Year
Participants were asked to rate their own symptoms for chronic graft versus host disease (cGVHD) severity per the NIH Consensus Development Project Criteria at baseline, after 24 weeks of treatment, and after one year of treatment. One data point in is a general rating of the severity of the participant's GVHD symptoms, ranging from 0 (GVHD symptoms not at all severe) to 10 (most severe GVHD symptoms possible). The baseline severity score is reported in the baseline characteristics.
Time frame: 24 weeks and 1 year
Population: One participant did not complete the cGVHD severity assessment at week 24. Two participants did not continue treatment long enough to self-assess for cGVHD severity at one year.
| Arm | Measure | Group | Value (MEAN) | Dispersion |
|---|---|---|---|---|
