Information
from the label
The
risk of malignancies including lymphoma is increased in patients with
rheumatoid arthritis. Immunomodulatory medicinal products may
increase the risk of malignancies including lymphoma. The clinical
data are insufficient to assess the potential incidence of
malignancies following exposure to baricitinib. Long-term safety
evaluations are ongoing.1
Clinical
Trial Criteria
Patients
with a history of malignancy were not uniformly excluded from the
BARI phase 3 clinical development program.2
Patients
who were able to participate in the BARI phase 3 clinical trials
included patients with
cervical
carcinoma in situ that had been resected with no evidence of
recurrence or metastatic disease for at least 3 years, and
basal
cell or squamous epithelial skin cancers that had been completely
resected with no evidence of recurrence for at least 3 years.2
However,
patients were excluded from the phase 3 trials if they had
a
history of lymphoproliferative disease
signs
or symptoms suggestive of possible lymphoproliferative disease,
including lymphadenopathy or splenomegaly
active
primary or recurrent malignant disease, or
been
in remission from clinically significant malignancy for <5
years.2
Baricitinib
Phase 3 Program
Each
of the 4 phase 3 studies in the clinical program evaluated a distinct
treatment population of patients with moderate-to-severe RA.
RA-BEGIN compared
BARI 4 mg monotherapy, BARI 4 mg plus MTX, and MTX monotherapy in
patients who had limited or no prior treatment with MTX and were
naïve to other DMARDs.3
RA-BEAM compared
BARI 4 mg vs placebo or adalimumab, with background MTX, in patients
with inadequate response to MTX.4
RA-BUILD compared
BARI 2 mg and 4 mg vs placebo, with background csDMARD therapy, in
patients with inadequate response to csDMARDs.5
RA-BEACON compared
BARI 2 mg and 4 mg vs placebo, with background csDMARD therapy,
in patients with an inadequate response to at least one TNF
inhibitor, who may also have had an inadequate response to one or
more non-TNF inhibitor biologic DMARDs.6
Patients
With Medical History of Malignancy in the Baricitinib Phase
3 Program
Medical
history, including malignancy, was recorded upon enrollment into each
of the BARI phase 3 clinical studies.
A
history of malignancy was defined as malignancy that was previously
diagnosed and resolved prior to study entry.
As
shown in Table 1. Comorbid
Conditions of Special Interest in the Baricitinib Phase 3 Studies ,
the number of patients who had a historical diagnosis of malignancy
at baseline included
1.8%
(12/684) in RA-BUILD
2.1%
(11/527) in RA-BEACON
1.3%
(17/1305) in RA-BEAM, and
2.2%
(13/584) in RA-BEGIN.2
Patients
With Preexisting Malignancy in the Baricitinib Phase 3
Program
A
preexisting malignancy was defined as malignancy that was previously
diagnosed and was ongoing at study entry.2
In
RA-BEGIN, 1 patient (0.2%) in the MTX treatment group reported
preexisting malignant tumors and skin neoplasms at enrollment Table

Studies .2
Efficacy
and Safety Analysis of Patients With a History of Malignancy
The
individual phase 3 clinical trials were not designed to detect
differences in the efficacy and safety of BARI for the treatment of
moderate to severe RA in patients with or without a medical history
or pre-existing condition of malignancy. Due to the small numbers of
patients with a medical history or preexisting condition of
malignancy in the BARI phase 3 clinical program for RA, an analysis
of the efficacy and safety of BARI in these patients is not feasible.
