E.2.1 | Main objective of the trial |
To evaluate the activity of ruxolitinib added to standard dose corticosteroids +/- CNI in pediatric subjects with moderate or severe treatment naivecGvHD or SR-cGvHD measured by overall response rate (ORR) at Cycle 7 Day 1 based on all subjects in the study |
|

ruxolitinib in treatment-naïve cGvHD
and SR-cGvHD pediatric subjects

- To assess non-relapse mortality (NRM)
- To assess overall survival (OS)
- To assess a reduction of at least ≥ 50% in daily corticosteroid use at Cycle 7 Day 1

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Male or female subjects age ≥28 days and <18
years at the time of informed consent.
• Subjects who have undergone alloSCT from any
donor source (matched unrelated donor, sibling, haploidentical) using bone marrow, peripheral blood stem cells, or cord blood. Recipients of myeloablative or reduced intensity conditioning are eligible.
• Subjects with diagnosed moderate to severe
cGvHD according to NIH 2014 Consensus Criteria
(Section 16.2) prior to Cycle 1 Day 1. Other possible
diagnoses for clinical symptoms supporting cGvHD
diagnoses must be excluded (e.g., infection, drug side effects, malignancy). Subjects must be either:
o Treatment-naive cGvHD subjects that have not
received any prior systemic treatment for cGvHD
except for a maximum 72h of prior systemic
corticosteroid therapy of methylprednisolone or
equivalent after the onset of chronic GvHD. Subjects
are allowed to have received prior systemic treatment for cGvHD prophylaxis (as long as the prophylaxis was started prior to the diagnosis of cGvHD).
OR
o Steroid-refractory moderate to severe cGvHD as
per institutional criteria, and still receiving systemic
corticosteroids for the treatment of cGvHD for a
duration of <18 months prior to Cycle 1 Day 1. In case the corticosteroids were interrupted due to response,
the duration of < 18 months applies to the last period of corticosteroid use.
Additional inclusion criteria as per fulll protocol may apply. |
|
E.4 | Principal exclusion criteria |
• SR-cGvHD subjects with a prior cGvHD
treatment with a JAK1- or a JAK2- or a JAK1/2-inhibitor, except when the subject achieved
complete or partial response and has been off JAK
inhibitor treatment for at least 4 weeks prior to Cycle Day 1 or up to 5 times the half-life of the prior JAK inhibitor, whichever is longer.
* Subjects who initiated systemic calcineurin
inhibitors (CNI; cyclosporine or tacrolimus) within 3
weeks prior to start of ruxolitinib on Cycle 1 Day 1.
Note: systemic CNI are allowed when initiated > 3
weeks from start of ruxolitinib.
• Failed prior alloSCT within the past 6 months
• Significant respiratory disease including subjects
who are on mechanical ventilation or who have a
resting oxygen saturation < 90% by pulse-oximetry on room-air.
• Impairment of gastrointestinal (GI) function
(unrelated to GvHD) or GI disease (unrelated to
GvHD) that may significantly alter the absorption of
oral ruxolitinib (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome or small bowel resection),
• Cholestatic disorders, or unresolved sinusoidal
obstructive syndrome/veno-occlusive disease of the
liver (defined as persistent bilirubin abnormalities not attributable to cGvHD and ongoing organ dysfunction)
• Presence of clinically active uncontrolled
infection including significant bacterial, fungal, viral or parasitic infection requiring treatment.
• Known human immunodeficiency virus (HIV)
infection.
• Evidence of uncontrolled hepatitis B virus (HBV)
or hepatitis C virus (HCV) based on assessment done
by Investigator or delegate.
• Known allergies, hypersensitivity, or intolerance
to any of the study medications, excipients, or similar compounds.
• History of bone disorders such as osteogenesis
imperfecta, rickets, renal osteodystrophy,
osteomyelitis, osteopenia, fibrous dysplasia,
osteomalacia etc. prior to the underlying diagnosis
which resulted in the alloSCT.
• History of endocrine or kidney related growth
retardation prior to the underlying diagnosis which
resulted in the alloSCT.
• Evidence of clinically active tuberculosis (clinical
diagnosis per local practice)
• Any corticosteroid therapy for indications other
than cGvHD at doses > 1 mg/kg/day methylprednisolone (or equivalent prednisone dose 1.25 mg/kg/day) within 7 days of the screening visit.
• History of progressive multifocal leukoencephalopathy (PML).
• Presence of severely impaired renal function
Other protocol-defined inclusion/exclusion criteria may apply. |

E.5 End points |
E.5.1 | Primary end point(s) |
Overall Response Rate ORR defined as the
proportion of subjects demonstrating a complete
response (CR) or partial response (PR) without the
requirement of additional systemic therapies for an
earlier progression, mixed response or non-response |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
1. Ruxolitinib concentrations by timepoint
2. Duration of response (DOR) assessed for
responders only. DOR is defined as the time from first response until cGvHD progression, death, or the date of addition of systemic therapies for cGvHD

at Cycle 4 Day 1
4. Proportion of subjects who achieved OR (CR+PR) at any time point
5. Composite time to event endpoint incorporating the following FFS events: i) relapse or recurrence of
underlying disease or death due to underlying disease, ii) non-relapse mortality, or iii) addition or initiation of another systemic therapy for cGvHD
6. Malignancy relapse/recurrence (MR) is defined
as the time from date of treatment assignment to
hematologic malignancy relapse/recurrence.
Calculated for subjects with underlying hematologic malignant disease
7. Non-relapse mortality (NRM), defined as the time
from date of treatment assignment to date of
death not preceded by underlying disease
relapse/recurrence.
8. Overall survival, defined as the time from the
date of treatment assignment to the date of death due to any cause
9. Proportion of subjects with ≥ 50% reduction from
baseline in daily corticosteroid dose at Cycle 7 Day 1
10. Proportion of subjects with reduction from
baseline in daily corticosteroid dose to ≤ 0.2
mg/kg/day methylprednisolone (or equivalent
dose of ≤ 0.25 mg/kg/day prednisone or
prednisolone) at Cycle 7 Day 1 |
