Clinical Trials Experience

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not predict the rates observed in a broader patient population in clinical practice. The clinical studies described in this subsection were conducted using XELJANZ tablets (referred to as “XELJANZ” in this subsection of labeling) and/or XELJANZ oral solution. A dosage of XELJANZ 10 mg twice daily is not recommended for the treatment of RA because of increased risks.

For the treatment of adults with moderately to severely active RA, the recommended dosage of XELJANZ is 5 mg twice daily and the recommended dosage for XELJANZ XR is 11 mg once daily. The safety of XELJANZ was also evaluated in two Phase 2 and five Phase 3 double-blind, placebo-controlled, multicenter trials in patients with RA. All seven trials included provisions for patients taking placebo to receive treatment with XELJANZ at Month 3 or Month 6 either by patient response (based on uncontrolled disease activity) or by design, so that adverse events cannot always be unambiguously attributed to a given treatment.

Therefore, some analyses that follow include patients who changed treatment by design or by patient response from placebo to XELJANZ in both the placebo and XELJANZ group of a given interval. Comparisons between placebo and XELJANZ groups were based on the first 3 months of exposure, and comparisons between XELJANZ 5 mg twice daily and XELJANZ 10 mg twice daily were based on the first 12 months of exposure. The long-term safety population includes all adults with RA who participated in a double-blind, placebo-controlled trial (including earlier development phase studies) and then participated in one of two long-term safety studies.

The design of the long-term safety studies allowed for modification of XELJANZ doses according to clinical judgment. This limits the interpretation of the long-term safety data with respect to dose. The most common serious adverse reactions were serious infections.

The proportion of patients who discontinued treatment due to any adverse reaction during the 0 to 3 months exposure in the double-blind, placebo-controlled trials was 4% for XELJANZ-treated patients and 3% for placebo-treated patients. The most commonly reported infections with XELJANZ were upper respiratory tract infections, nasopharyngitis, and urinary tract infections (4%, 3%, and 2% of patients, respectively). The most common serious infections included pneumonia, cellulitis, herpes zoster, and urinary tract infection.

Tuberculosis: In the seven placebo-controlled trials in patients with RA, during the 0 to 3 months exposure, tuberculosis (TB) was not reported in patients who received placebo, XELJANZ 5 mg twice daily, or XELJANZ 10 mg twice daily. Cases of disseminated TB were also reported. The median XELJANZ exposure prior to diagnosis of TB was 10 months (range from 152 to 960 days).

The median XELJANZ exposure prior to diagnosis of an opportunistic infection was 8 months (range from 41 to 698 days). One of these malignancies was a case of lymphoma that occurred during the 0-to-12-month period in a patient treated with XELJANZ 10 mg twice daily. The most common types of malignancy, including malignancies observed during the long-term extension in XELJANZ-treated patients, were lung and breast cancer, followed by gastric, colorectal, renal cell, prostate cancer, lymphoma, and malignant melanoma.

Confirmed lymphocyte counts less than 500 cells/mm 3 were associated with an increased incidence of treated and serious infections. There were no confirmed decreases in ANC below 500 cells/mm 3 observed in any treatment group. There was no clear relationship between neutropenia and the occurrence of serious infections.

In the long-term safety population, the pattern and incidence of confirmed decreases in ANC remained consistent with what was seen in the placebo-controlled clinical trials. Liver Enzyme Elevations: Confirmed increases in liver enzymes greater than 3 times the upper limit of normal (3× ULN) were observed in patients with RA treated with XELJANZ. In patients experiencing liver enzyme elevation, modification of treatment regimen, such as reduction in the dose of concomitant DMARD, interruption of XELJANZ, or reduction in XELJANZ dosage, resulted in decrease or normalization of liver enzymes.

In the placebo-controlled monotherapy trials (0–3 months), no differences in the incidence of ALT or AST elevations were observed between the placebo, and XELJANZ 5 mg, and 10 mg twice daily groups. One case of drug-induced liver injury was reported in a patient treated with XELJANZ 10 mg twice daily for approximately 2.5 months. The patient developed symptomatic elevations of AST and ALT greater than 3× ULN and bilirubin elevations greater than 2× ULN, which required hospitalizations and a liver biopsy.

Lipid Elevations: In the placebo-controlled clinical trials in patients with RA, dose-related elevations in lipid parameters (total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides) were observed at one month of exposure and remained stable thereafter. Changes in lipid parameters during the first 3 months of exposure in the placebo-controlled clinical trials are summarized below: • Mean LDL cholesterol increased by 15% in the XELJANZ 5 mg twice daily arm and 19% in the XELJANZ 10 mg twice daily arm. • Mean HDL cholesterol increased by 10% in the XELJANZ 5 mg twice daily arm and 12% in the XELJANZ 10 mg twice daily arm. • Mean LDL/HDL ratios were essentially unchanged in XELJANZ-treated patients. In a placebo-controlled clinical trial, elevations in LDL cholesterol and ApoB decreased to pretreatment levels in response to statin therapy.

In the long-term safety population, elevations in lipid parameters remained consistent with what was seen in the placebo-controlled clinical trials. Serum Creatinine Elevations: In the placebo-controlled clinical trials in patients with RA, dose-related elevations in serum creatinine were observed with XELJANZ treatment. The mean increase in serum creatinine was <0.1 mg/dL in the 12-month pooled safety analysis; however, with increasing duration of exposure in the long-term extensions, up to 2% of patients were discontinued from XELJANZ treatment due to the protocol-specified discontinuation criterion of an increase in creatinine by more than 50% of baseline.

The clinical significance of the observed serum creatinine elevations is unknown. Common Adverse Reactions Table 5 displays adverse reactions that occurred in 2% or more of patients on XELJANZ 5 mg or 10 mg twice daily and at least 1% greater than in XELJANZ-treated patients that observed in placebo-treated patients with or without DMARD in the RA trials. Table 5: Common Adverse Reactions reported in ≥2% of patients treated with either dose of XELJANZ and ≥1% greater than that reported for placebo. in Clinical Trials of XELJANZ for the Treatment of Rheumatoid Arthritis in Adults With or Without Concomitant DMARDs (0–3 Months) Preferred Term Placebo XELJANZ 5 mg Twice Daily XELJANZ 10 mg Twice Daily The recommended dose of XELJANZ for the treatment of RA is 5 mg twice daily. 1 2 2 Other adverse reactions that occurred in placebo-controlled and open-label extension studies in patients with RA included: Blood and lymphatic system disorders: Anemia Infections and infestations: Diverticulitis Metabolism and nutrition disorders: Dehydration Psychiatric disorders: Insomnia Nervous system disorders: Paresthesia Respiratory, thoracic and mediastinal disorders: Dyspnea, cough, sinus congestion, interstitial lung disease (cases were limited to patients with RA and some were fatal) Gastrointestinal disorders: Abdominal pain, dyspepsia, vomiting, gastritis, nausea Hepatobiliary disorders: Hepatic steatosis Skin and subcutaneous tissue disorders: Rash, erythema, pruritus Musculoskeletal, connective tissue and bone disorders: Musculoskeletal pain, arthralgia, tendonitis, joint swelling Neoplasms benign, malignant and unspecified (including cysts and polyps): Non-melanoma skin cancers General disorders and administration site conditions: Pyrexia, fatigue, peripheral edema Clinical Experience in Methotrexate-Naïve Patients Study RA-VI was an active-controlled clinical trial in methotrexate-naïve patients.

The safety experience in these patients was consistent with Studies RA-I through V. Adverse Reactions in Adults with Psoriatic Arthritis The safety of XELJANZ was evaluated in 2 double-blind Phase 3 clinical trials in adults with active psoriatic arthritis (PsA): • Study PsA-I (NCT01877668) had a duration of 12 months and enrolled adults who had an inadequate response to a nonbiologic DMARD and who were naïve to treatment with a TNF blocker. Study PsA-I included a 3-month placebo-controlled period and also included adalimumab 40 mg subcutaneously once every 2 weeks for 12 months. • Study PsA-II (NCT01882439) had a duration of 6 months and enrolled adults who had an inadequate response to at least one approved TNF blocker.

This clinical trial included a 3-month placebo-controlled period. All patients in the clinical trials in patients with PsA were required to receive treatment with a stable dose of a nonbiologic DMARD. No lymphomas were reported.

Malignancies have also been observed in the long-term extension study in patients with PsA treated with XELJANZ. The safety profile observed in adults with active PsA treated with XELJANZ was consistent with the safety profile observed in adults with RA. Adverse Reactions in Adults with Ankylosing Spondylitis The safety of XELJANZ was evaluated in adults with active ankylosing spondylitis (AS) in a double-blind placebo-controlled Phase 3 clinical trial (Study AS-I) and in a dose-ranging Phase 2 clinical trial (Study AS-II). • Study AS-I (NCT03502616) had a duration of 48 weeks and enrolled adults who had an inadequate response to at least 2 NSAIDs.

Study AS-I included a 16-week double-blind period in which patients received XELJANZ 5 mg or placebo twice daily and a 32-week open-label treatment period in which all patients received XELJANZ 5 mg twice daily. • Study AS-II (NCT01786668) had a duration of 16 weeks and enrolled adults who had an inadequate response to at least 2 NSAIDs. Of these, 316 patients were treated with XELJANZ 5 mg twice daily for up to 48 weeks. Concomitant treatment with stable doses of nonbiologic DMARDs, NSAIDs, or corticosteroids (≤10 mg/day) was permitted.

Adverse Reactions in Pediatric Patients 2 Years of Age and Older with Polyarticular Course Juvenile Idiopathic Arthritis XELJANZ tablets and XELJANZ oral solution 5 mg twice daily or weight-based equivalent twice daily was studied in 225 pediatric patients from 2 years to 17 years of age in Study pcJIA-I and one open-label extension study (Study A3921145). The total patient exposure (defined as patients who received at least one dose of XELJANZ tablets or XELJANZ oral solution) was 105.6 patient-years in Study pcJIA-I and 777.5 patient-years in Study A3921145. In general, the types of adverse reactions in pediatric patients 2 years of age and older with pcJIA, were consistent with those seen in adults with RA and PsA (see Adverse Reactions in Adults with Rheumatoid Arthritis and Adverse Reactions in Adults with Psoriatic Arthritis ).

Adverse Reactions in Adults with Ulcerative Colitis The safety of XELJANZ has been evaluated in adults with moderately to severely active UC in 4 randomized, double-blind, placebo-controlled trials (UC-I, UC-II, UC-III, and dose-ranging UC-V) and an open-label long-term extension study (UC-IV). Adverse reactions reported in ≥5% of patients treated with either XELJANZ 5 mg or 10 mg twice daily and ≥1% greater than reported in patients receiving placebo in either the induction or maintenance clinical trials of patients with UC were: nasopharyngitis, elevated cholesterol levels, headache, upper respiratory tract infection, increased blood creatine phosphokinase, rash, diarrhea, and herpes zoster. Induction Trials in Adults with UC Common adverse reactions reported in ≥2% of patients treated with XELJANZ 10 mg twice daily and ≥1% greater in XELJANZ-treated patients than placebo-treated patients in the 3 induction trials of patients with UC (Studies UC-I, UC-II, and UC-V) were: headache, nasopharyngitis, elevated cholesterol levels, acne, increased blood creatine phosphokinase, and pyrexia.

Maintenance Trial in Adults with UC Common adverse reactions reported in ≥4% of patients treated with either dosage of XELJANZ and ≥1% greater than reported in patients treated with placebo in the maintenance trial of patients with UC (Study UC-III) are shown in Table 6. During the UC controlled clinical studies (8-week induction and 52-week maintenance studies), which included 1,220 patients, 0 cases of solid cancer or lymphoma were observed in XELJANZ-treated patients. In the long-term extension study, malignancies (including solid cancers, lymphomas and NMSC) were observed in patients treated with XELJANZ 5 mg and 10 mg twice daily.

Five cases of pulmonary embolism were reported in patients taking XELJANZ 10 mg twice daily, including one fatality in a patient with advanced cancer.

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of XELJANZ (tablets and oral solution) and XELJANZ XR (extended-release tablets). Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune system disorders: Drug hypersensitivity (events such as angioedema and urticaria have been observed) Metabolism and nutrition disorders: Hypoglycemia Skin and subcutaneous tissue disorders: Acne

Table 7 includes drugs with clinically significant drug interactions when concomitantly used with XELJANZ (tablets and oral solution) and XELJANZ XR (extended-release tablets) and instructions for preventing or managing them. Table 7: Clinically Significant Interactions Affecting XELJANZ/XELJANZ XR When Concomitantly Used with Other Drugs Strong CYP3A4 Inhibitors (e.g., ketoconazole) Clinical Impact Increased exposure to tofacitinib Intervention Dosage modification of XELJANZ/XELJANZ XR is recommended Moderate CYP3A4 Inhibitors Concomitantly Used with Strong CYP2C19 Inhibitors (e.g., fluconazole) Clinical Impact Increased exposure to tofacitinib Intervention Dosage modification of XELJANZ/XELJANZ XR is recommended Strong CYP3A4 Inducers (e.g., rifampin) Clinical Impact Decreased exposure to tofacitinib and may result in loss of or reduced clinical response Intervention Concomitant use with XELJANZ/XELJANZ XR is not recommended Immunosuppressive Drugs (e.g., azathioprine, tacrolimus, cyclosporine) Clinical Impact Risk of added immunosuppression; concomitant use of XELJANZ/XELJANZ XR with biologic DMARDs or potent immunosuppressants has not been studied in patients with RA, PsA, AS, UC, or pcJIA. Intervention Concomitant use with XELJANZ/XELJANZ XR is not recommended See FPI for clinically significant drug interactions.

Pregnancy Risk Summary The available data with XELJANZ (tablets and oral solution) and XELJANZ XR (extended-release tablets) from a pregnancy exposure registry that enrolled 11 exposed pregnant females, pharmacovigilance, and published literature are insufficient to draw conclusions about a drug‑associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and the fetus associated with RA and UC in pregnancy (see Clinical Considerations ). In animal reproduction studies, fetocidal and teratogenic effects were noted when pregnant rats and rabbits received tofacitinib during the period of organogenesis at exposures multiples of 73-times and 6.3-times the maximum recommended dose of 10 mg twice daily, respectively.

Further, in a peri- and post-natal study in rats, tofacitinib resulted in reductions in live litter size, postnatal survival, and pup body weights at exposure multiples of approximately 73-times the recommended dosage of 5 mg twice daily and approximately 36 times the maximum recommended dosage of 10 mg twice daily, respectively (see Data ). The background risks of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

The background risks in the U.S. general population of major birth defects and miscarriages are of clinically recognized pregnancies, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk: Published data suggest that increased disease activity is associated with the risk of developing adverse pregnancy outcomes in women with RA or UC. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 grams) infants, and small for gestational age at birth.

Data Animal Data: In a rat embryofetal developmental study, in which pregnant rats received tofacitinib during organogenesis, tofacitinib was teratogenic at exposure levels approximately 146 times the recommended dose of 5 mg twice daily, and approximately 73 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 100 mg/kg/day in rats). Teratogenic effects consisted of external and soft tissue malformations of anasarca and membranous ventricular septal defects, respectively; and skeletal malformations or variations (absent cervical arch; bent femur, fibula, humerus, radius, scapula, tibia, and ulna; sternoschisis; absent rib; misshapen femur; branched rib; fused rib; fused sternebra; and hemicentric thoracic centrum). In addition, there was an increase in post-implantation loss, consisting of early and late resorptions, resulting in a reduced number of viable fetuses.

Mean fetal body weight was reduced. No developmental toxicity was observed in rats at exposure levels approximately 58 times the recommended dose of 5 mg twice daily, and approximately 29 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 30 mg/kg/day in pregnant rats). In a rabbit embryofetal developmental study in which pregnant rabbits received tofacitinib during the period of organogenesis, tofacitinib was teratogenic at exposure levels approximately 13 times the recommended dose of 5 mg twice daily, and approximately 6.3 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 30 mg/kg/day in rabbits) in the absence of signs of maternal toxicity.

Teratogenic effects included thoracogastroschisis, omphalocele, membranous ventricular septal defects, and cranial/skeletal malformations (microstomia, microphthalmia), mid-line and tail defects. In addition, there was an increase in post-implantation loss associated with late resorptions. In a peri- and postnatal development study in pregnant rats that received tofacitinib from gestation day 6 through day 20 of lactation, there were reductions in live litter size, postnatal survival, and pup body weights at exposure levels approximately 73 times the recommended dose of 5 mg twice daily, and approximately 36 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 50 mg/kg/day in rats).

There was no effect on behavioral and learning assessments, sexual maturation or the ability of the F1 generation rats to mate and produce viable F2 generation fetuses in rats at exposure levels approximately 17 times the recommended dose of 5 mg twice daily, and approximately 8.3 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 10 mg/kg/day in rats).

Pediatric Use The safety and effectiveness of XELJANZ (tablets and oral solution) in pediatric patients for indications, other than in patients with active pcJIA and PsA, have not been established. The safety and effectiveness of XELJANZ have not been established in pediatric patients less than 2 years of age. The safety and effectiveness of XELJANZ XR (extended-release tablets) in pediatric patients have not been established.

Polyarticular Course Juvenile Idiopathic Arthritis (pcJIA) The safety and effectiveness of XELJANZ (tablets and oral solution) for the treatment of active pcJIA have been established in pediatric patients 2 years of age and older who have had an inadequate response or intolerance to one or more TNF blockers. Use of XELJANZ for this indication is supported by evidence from adequate and well-controlled studies of XELJANZ tablets in adults with RA, pharmacokinetic (PK) data from adult patients with RA, and with additional safety, efficacy, and PK data from a clinical trial of XELJANZ in pediatric patients 2 years and older with active pcJIA (Study pcJIA-I). Adverse reactions observed in pediatric patients with pcJIA who received XELJANZ were consistent with those reported in adults with RA.

Use of XELJANZ for this indication is supported by evidence from well-controlled studies of XELJANZ tablets in adults with PsA, PK data from adults with PsA, and PK data from a clinical trial of XELJANZ in 225 pediatric patients with JIA, and safety data from 280 pediatric patients 2 years of age and older with JIA. Following administration of the recommended XELJANZ dosage in pediatric patients 2 years of age and older with PsA, tofacitinib plasma exposures are predicted to be comparable to those observed in adults with PsA based on population PK modeling and simulation. Systemic Juvenile Idiopathic Arthritis The safety and effectiveness of XELJANZ for the treatment of pediatric patients with systemic juvenile idiopathic arthritis (sJIA) have not been established.

The results from a two-part study (an open-label, run-in phase, followed by a double-blind, placebo-controlled, randomized event-driven withdrawal phase) in 100 patients 2 years to 17 years of age with sJIA with active systemic features did not demonstrate that XELJANZ (dosed at 5 mg twice daily or body weight-based equivalent twice daily) was efficacious in the treatment of sJIA with active systemic features. Of the 100 patients enrolled in the open-label run-in phase, 59 (59%) patients achieved a clinical response and were eligible for the double-blind withdrawal phase. There were 28 patients randomized to XELJANZ and 31 patients to placebo.

The study data were insufficient to demonstrate efficacy and, therefore, XELJANZ is not recommended for the treatment of sJIA. Adverse reactions observed in pediatric patients with sJIA receiving XELJANZ/XELJANZ oral solution were consistent with those reported in pcJIA and RA patients.

There is no specific antidote for overdose with XELJANZ (tablets and oral solution) and XELJANZ XR (extended-release tablets). In case of an overdose, it is recommended that the patient be monitored for signs and symptoms of adverse reactions. In a study in patients with end-stage renal disease (ESRD) undergoing hemodialysis, plasma tofacitinib concentrations declined more rapidly during the period of hemodialysis and dialyzer efficiency, calculated as dialyzer clearance/blood flow entering the dialyzer, was high.

However, due to the significant non-renal clearance of tofacitinib, the fraction of total elimination occurring by hemodialysis was small, and thus, limits the value of hemodialysis for treatment of overdose with XELJANZ/XELJANZ XR. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
