Hadlima

Patients treated with adalimumab products, including HADLIMA, are at increased risk for developing serious infections involving various organ systems and sites that may lead to hospitalization or death. Opportunistic infections due to bacterial, mycobacterial, invasive fungal, viral, parasitic, or other opportunistic pathogens including aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, histoplasmosis, legionellosis, listeriosis, pneumocystosis and tuberculosis have been reported with TNF blockers. Patients have frequently presented with disseminated rather than localized disease.

The concomitant use of a TNF blocker and abatacept or anakinra was associated with a higher risk of serious infections in patients with rheumatoid arthritis (RA); therefore, the concomitant use of HADLIMA and these biologic products is not recommended in the treatment of patients with RA

Treatment with HADLIMA should not be initiated in patients with an active infection, including localized infections. Patients 65 years of age and older, patients with co-morbid conditions and/or patients taking concomitant immunosuppressants (such as corticosteroids or methotrexate), may be at greater risk of infection. Consider the risks and benefits of treatment prior to initiating therapy in patients:

• •with chronic or recurrent infection;
• •who have been exposed to tuberculosis;
• •with a history of an opportunistic infection;
• •who have resided or traveled in areas of endemic tuberculosis or endemic mycoses, such as histoplasmosis, coccidioidomycosis, or blastomycosis; or
• •with underlying conditions that may predispose them to infection.

Cases of reactivation of tuberculosis and new onset tuberculosis infections have been reported in patients receiving adalimumab products, including patients who have previously received treatment for latent or active tuberculosis. Reports included cases of pulmonary and extrapulmonary (i.e., disseminated) tuberculosis. Evaluate patients for tuberculosis risk factors and test for latent infection prior to initiating HADLIMA and periodically during therapy.

Treatment of latent tuberculosis infection prior to therapy with TNF blocking agents has been shown to reduce the risk of tuberculosis reactivation during therapy. Prior to initiating HADLIMA, assess if treatment for latent tuberculosis is needed; and consider an induration of ≥ 5 mm a positive tuberculin skin test result, even for patients previously vaccinated with Bacille Calmette- Guerin (BCG).

Consider anti-tuberculosis therapy prior to initiation of HADLIMA in patients with a past history of latent or active tuberculosis in whom an adequate course of treatment cannot be confirmed, and for patients with a negative test for latent tuberculosis but having risk factors for tuberculosis infection. Despite prophylactic treatment for tuberculosis, cases of reactivated tuberculosis have occurred in patients treated with adalimumab products. Consultation with a physician with expertise in the treatment of tuberculosis is recommended to aid in the decision whether initiating anti- tuberculosis therapy is appropriate for an individual patient.

Strongly consider tuberculosis in the differential diagnosis in patients who develop a new infection during HADLIMA treatment, especially in patients who have previously or recently traveled to countries with a high prevalence of tuberculosis, or who have had close contact with a person with active tuberculosis.

Closely monitor patients for the development of signs and symptoms of infection during and after treatment with HADLIMA, including the development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. Tests for latent tuberculosis infection may also be falsely negative while on therapy with HADLIMA.

Discontinue HADLIMA if a patient develops a serious infection or sepsis. For a patient who develops a new infection during treatment with HADLIMA, closely monitor them, perform a prompt and complete diagnostic workup appropriate for an immunocompromised patient, and initiate appropriate antimicrobial therapy.

If patients develop a serious systemic illness and they reside or travel in regions where mycoses are endemic, consider invasive fungal infection in the differential diagnosis. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Consider appropriate empiric antifungal therapy, taking into account both the risk for severe fungal infection and the risks of antifungal therapy, while a diagnostic workup is being performed. To aid in the management of such patients, consider consultation with a physician with expertise in the diagnosis and treatment of invasive fungal infections.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The most common adverse reaction with adalimumab was injection site reactions. In placebo- controlled trials, 20% of subjects treated with adalimumab developed injection site reactions (erythema and/or itching, hemorrhage, pain or swelling), compared to 14% of subjects receiving placebo. Most injection site reactions were described as mild and generally did not necessitate drug discontinuation.

The proportion of subjects who discontinued treatment due to adverse reactions during the double-blind, placebo-controlled portion of studies in subjects with RA (i.e., Studies RA-I, RA- II, RA-III and RA-IV) was 7% for subjects taking adalimumab and 4% for placebo-treated subjects. The most common adverse reactions leading to discontinuation of adalimumab in these RA studies were clinical flare reaction (0.7%), rash (0.3%) and pneumonia (0.3%).

In the controlled portions of the 39 global adalimumab clinical trials in adult subjects with RA, PsA, AS, CD, UC, Ps, HS, and UV, the rate of serious infections was 4.3 per 100 patient-years in 7973 adalimumab-treated subjects versus a rate of 2.9 per 100 patient-years in 4848 control-treated subjects. Serious infections observed included pneumonia, septic arthritis, prosthetic and post- surgical infections, erysipelas, cellulitis, diverticulitis, and pyelonephritis

In 52 global controlled and uncontrolled clinical trials in RA, PsA, AS, CD, UC, Ps, HS, and UV, that included 24,605 adalimumab-treated subjects, the rate of reported active tuberculosis was 0.20 per 100 patient-years and the rate of positive PPD conversion was 0.09 per 100 patient-years. In a subgroup of 10,113 U.S. and Canadian adalimumab-treated subjects, the rate of reported active TB was 0.05 per 100 patient-years and the rate of positive PPD conversion was 0.07 per 100 patient- years. These trials included reports of miliary, lymphatic, peritoneal, and pulmonary TB. Most of the TB cases occurred within the first eight months after initiation of therapy and may reflect recrudescence of latent disease. In these global clinical trials, cases of serious opportunistic infections have been reported at an overall rate of 0.05 per 100 patient-years. Some cases of serious opportunistic infections and TB have been fatal

In the rheumatoid arthritis controlled trials, 12% of subjects treated with adalimumab and 7% of placebo-treated subjects that had negative baseline ANA titers developed positive titers at week 24. Two subjects out of 3046 treated with adalimumab developed clinical signs suggestive of new- onset lupus-like syndrome. The subjects improved following discontinuation of therapy. No subjects developed lupus nephritis or central nervous system symptoms. The impact of long-term treatment with adalimumab products on the development of autoimmune diseases is unknown.

There have been reports of severe hepatic reactions including acute liver failure in subjects receiving TNF-blockers. In controlled Phase 3 trials of adalimumab (40 mg SC every other week) in subjects with RA, PsA, and AS with control period duration ranging from 4 to 104 weeks, ALT elevations ≥ 3 x ULN occurred in 3.5% of adalimumab-treated subjects and 1.5% of control- treated subjects. Since many of these subjects in these trials were also taking medications that cause liver enzyme elevations (e.g., NSAIDS, MTX), the relationship between adalimumab and the liver enzyme elevations is not clear. In a controlled Phase 3 trial of adalimumab in subjects with polyarticular JIA who were 4 to 17 years, ALT elevations ≥ 3 x ULN occurred in 4.4% of adalimumab-treated subjects and 1.5% of control-treated subjects (ALT more common than AST); liver enzyme test elevations were more frequent among those treated with the combination of adalimumab and MTX than those treated with adalimumab alone. In general, these elevations did not lead to discontinuation of adalimumab treatment. No ALT elevations ≥3 x ULN occurred in the open-label study of adalimumab in subjects with polyarticular JIA who were 2 to <4 years.

In controlled Phase 3 trials of adalimumab (initial doses of 160 mg and 80 mg, or 80 mg and 40 mg on Days 1 and 15, respectively, followed by 40 mg every other week) in adult subjects with Crohn’s Disease with a control period duration ranging from 4 to 52 weeks, ALT elevations ≥ 3 x ULN occurred in 0.9% of adalimumab-treated subjects and 0.9% of control-treated subjects. In the Phase 3 trial of adalimumab in pediatric subjects with Crohn’s disease which evaluated efficacy and safety of two body weight based maintenance dose regimens following body weight based induction therapy up to 52 weeks of treatment, ALT elevations ≥ 3 x ULN occurred in 2.6% (5/192) of subjects, of whom 4 were receiving concomitant immunosuppressants at baseline; none of these subjects discontinued due to abnormalities in ALT tests. In controlled Phase 3 trials of adalimumab (initial doses of 160 mg and 80 mg on Days 1 and 15 respectively, followed by 40 mg every other week) in adult subjects with UC with control period duration ranging from 1 to 52 weeks, ALT elevations ≥3 x ULN occurred in 1.5% of adalimumab-treated subjects and 1.0% of control-treated subjects. In controlled Phase 3 trials of adalimumab (initial dose of 80 mg then 40 mg every other week) in subjects with Ps with control period duration ranging from 12 to 24 weeks, ALT elevations ≥ 3 x ULN occurred in 1.8% of adalimumab-treated subjects and 1.8% of control-treated subjects. In controlled trials of adalimumab (initial doses of 160 mg at Week 0 and 80 mg at Week 2, followed by 40 mg every week starting at Week 4), in subjects with HS with a control period duration ranging from 12 to 16 weeks, ALT elevations ≥ 3 x ULN occurred in 0.3% of adalimumab-treated subjects and 0.6% of control-treated subjects. In controlled trials of adalimumab (initial doses of 80 mg at Week 0 followed by 40 mg every other week starting at Week 1) in adult subjects with uveitis with an exposure of 165.4 PYs and 119.8 PYs in adalimumab-treated and control-treated subjects, respectively, ALT elevations ≥ 3 x ULN occurred in 2.4% of adalimumab-treated subjects and 2.4% of control-treated subjects.

The data described below reflect exposure to adalimumab in 2468 subjects, including 2073 exposed for 6 months, 1497 exposed for greater than one year and 1380 in adequate and well-controlled studies (Studies RA-I, RA-II, RA-III, and RA-IV). Adalimumab was studied primarily in placebo- controlled trials and in long-term follow up studies for up to 36 months duration. The population had a mean age of 54 years, 77% were female, 91% were Caucasian and had moderately to severely active rheumatoid arthritis. Most subjects received 40 mg adalimumab every other week

Table 1summarizes reactions reported at a rate of at least 5% in subjects treated with adalimumab 40 mg every other week compared to placebo and with an incidence higher than placebo. In Study RA-III, the types and frequencies of adverse reactions in the second year open-label extension were similar to those observed in the one-year double-blind portion.

Other infrequent serious adverse reactions that do not appear in the Warnings and Precautions or Adverse Reaction sections that occurred at an incidence of less than 5% in adalimumab-treated subjects in RA (RA-I, RA-II, RA-III, and RA-IV) studies were:

In general, the adverse reactions in the adalimumab-treated subjects in the polyarticular juvenile idiopathic arthritis (JIA) trials (Studies JIA-I and JIA-II)

In Study JIA-I, adalimumab was studied in 171 subjects who were 4 to 17 years of age, with polyarticular JIA. Severe adverse reactions reported in the study included neutropenia, streptococcal pharyngitis, increased aminotransferases, herpes zoster, myositis, metrorrhagia, and appendicitis. Serious infections were observed in 4% of subjects within approximately 2 years of initiation of treatment with adalimumab and included cases of herpes simplex, pneumonia, urinary tract infection, pharyngitis, and herpes zoster.

In Study JIA-I, 45% of subjects experienced an infection while receiving adalimumab with or without concomitant MTX in the first 16 weeks of treatment. The types of infections reported in adalimumab-treated subjects were generally similar to those commonly seen in polyarticular JIA subjects who are not treated with TNF blockers. Upon initiation of treatment, the most common adverse reactions occurring in this population treated with adalimumab were injection site pain and injection site reaction (19% and 16%, respectively). A less commonly reported adverse event in subjects receiving adalimumab was granuloma annulare which did not lead to discontinuation of adalimumab treatment.

In the first 48 weeks of treatment in Study JIA-I, non-serious hypersensitivity reactions were seen in approximately 6% of subjects and included primarily localized allergic hypersensitivity reactions and allergic rash.

In Study JIA-I, 10% of subjects treated with adalimumab who had negative baseline anti-dsDNA antibodies developed positive titers after 48 weeks of treatment. No subject developed clinical signs of autoimmunity during the clinical trial.

Approximately 15% of subjects treated with adalimumab developed mild-to-moderate elevations of creatine phosphokinase (CPK) in Study JIA-I. Elevations exceeding 5 times the upper limit of normal were observed in several subjects. CPK concentrations decreased or returned to normal in all subjects. Most subjects were able to continue adalimumab without interruption.

In Study JIA-II, adalimumab was studied in 32 subjects who were 2 to <4 years of age or 4 years of age and older weighing <15 kg with polyarticular JIA. The safety profile for this population was similar to the safety profile seen in subjects 4 to 17 years of age with polyarticular JIA.

In Study JIA-II, 78% of subjects experienced an infection while receiving adalimumab. These included nasopharyngitis, bronchitis, upper respiratory tract infection, otitis media, and were mostly mild to moderate in severity. Serious infections were observed in 9% of subjects receiving adalimumab in the study and included dental caries, rotavirus gastroenteritis, and varicella.

In Study JIA-II, non-serious allergic reactions were observed in 6% of subjects and included intermittent urticaria and rash, which were all mild in severity.

Adalimumab has been studied in 395 subjects with psoriatic arthritis (PsA) in two placebo- controlled trials and in an open label study and in 393 subjects with ankylosing spondylitis (AS) in two placebo-controlled studies

During the 4-week open label induction phase of Study PCD-I, the most common adverse reactions occurring in the pediatric population treated with adalimumab were injection site pain and injection site reaction (6% and 5%, respectively).

A total of 67% of children experienced an infection while receiving adalimumab in Study PCD-I. These included upper respiratory tract infection and nasopharyngitis.

A total of 5% of children experienced a serious infection while receiving adalimumab in Study PCD-I. These included viral infection, device related sepsis (catheter), gastroenteritis, H1N1 influenza, and disseminated histoplasmosis.

In Study PCD-I, allergic reactions were observed in 5% of children which were all non-serious and were primarily localized reactions.

Adalimumab has been studied in 1696 subjects with plaque psoriasis (Ps) in placebo-controlled and open-label extension studies

Adalimumab has been studied in 727 subjects with hidradenitis suppurativa (HS) in three placebo- controlled studies and one open-label extension study

Flare of HS, defined as ≥25% increase from baseline in abscesses and inflammatory nodule counts and with a minimum of 2 additional lesions, was documented in 22 (22%) of the 100 subjects who were withdrawn from adalimumab treatment following the primary efficacy timepoint in two studies.

Adalimumab has been studied in 464 adult subjects with uveitis (UV) in placebo-controlled and open-label extension studies

Consider the risks and benefits of TNF-blocker treatment including HADLIMA prior to initiating therapy in patients with a known malignancy other than a successfully treated non-melanoma skin cancer (NMSC) or when considering continuing a TNF blocker in patients who develop a malignancy.

In the controlled portions of clinical trials of some TNF-blockers, including adalimumab products, more cases of malignancies have been observed among TNF-blocker-treated adult subjects compared to control-treated adult subjects. During the controlled portions of 39 global adalimumab clinical trials in adult patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), Crohn’s disease (CD), ulcerative colitis (UC), plaque psoriasis (Ps), hidradenitis suppurativa (HS), and uveitis (UV), malignancies, other than non-melanoma (basal cell and squamous cell) skin cancer, were observed at a rate (95% confidence interval) of 0.7 (0.48, 1.03) per 100 patient-years among 7973 adalimumab-treated subjects versus a rate of 0.7 (0.41, 1.17) per 100 patient-years among 4848 control-treated subjects (median duration of treatment of 4 months for adalimumab-treated subjects and 4 months for control-treated subjects). In 52 global controlled and uncontrolled clinical trials of adalimumab in adult patients with RA, PsA, AS, CD, UC, Ps, HS, and UV, the most frequently observed malignancies, other than lymphoma and NMSC, were breast, colon, prostate, lung, and melanoma. The malignancies in adalimumab-treated subjects in the controlled and uncontrolled portions of the studies were similar in type and number to what would be expected in the general U.S. population according to the SEER database (adjusted for age, gender, and race).¹

In controlled trials of other TNF blockers in adult patients at higher risk for malignancies (i.e., subjects with COPD with a significant smoking history and cyclophosphamide-treated patients with Wegener’s granulomatosis), a greater portion of malignancies occurred in the TNF blocker group compared to the control group.

During the controlled portions of 39 global adalimumab clinical trials in adult patients with RA, PsA, AS, CD, UC, Ps, HS, and UV, the rate (95% confidence interval) of NMSC was 0.8 (0.52, 1.09) per 100 patient-years among adalimumab-treated subjects and 0.2 (0.10, 0.59) per 100 patient-years among control-treated subjects. Examine all patients, and in particular patients with a medical history of prior prolonged immunosuppressant therapy or psoriasis patients with a history of PUVA treatment for the presence of NMSC prior to and during treatment with HADLIMA.

In the controlled portions of clinical trials of all the TNF-blockers in adults, more cases of lymphoma have been observed among TNF-blocker-treated subjects compared to control-treated subjects. In the controlled portions of 39 global adalimumab clinical trials in adult patients with RA, PsA, AS, CD, UC, Ps, HS, and UV, 2 lymphomas occurred among 7973 adalimumab-treated subjects versus 1 among 4848 control-treated subjects. In 52 global controlled and uncontrolled clinical trials of adalimumab in adult patients with RA, PsA, AS, CD, UC, Ps, HS, and UV with a median duration of approximately 0.7 years, including 24,605 subjects and over 40,215 patient- years of adalimumab, the observed rate of lymphomas was approximately 0.11 per 100 patient- years. This is approximately 3-fold higher than expected in the general U.S. population according to the SEER database (adjusted for age, gender, and race).¹Rates of lymphoma in clinical trials of adalimumab cannot be compared to rates of lymphoma in clinical trials of other TNF blockers and may not predict the rates observed in a broader patient population. Patients with RA and other chronic inflammatory diseases, particularly those with highly active disease and/or chronic exposure to immunosuppressant therapies, may be at a higher risk (up to several fold) than the general population for the development of lymphoma, even in the absence of TNF blockers. Post-marketing cases of acute and chronic leukemia have been reported in association with TNF-blocker use in RA and other indications. Even in the absence of TNF-blocker therapy, patients with RA may be at a higher risk (approximately 2-fold) than the general population for the development of leukemia.

Malignancies, some fatal, have been reported among children, adolescents, and young adults who received treatment with TNF-blockers (initiation of therapy ≤ 18 years of age), of which HADLIMA is a member. Approximately half the cases were lymphomas, including Hodgkin's and non-Hodgkin's lymphoma. The other cases represented a variety of different malignancies and included rare malignancies usually associated with immunosuppression and malignancies that are not usually observed in children and adolescents. The malignancies occurred after a median of 30 months of therapy (range 1 to 84 months). Most of the patients were receiving concomitant immunosuppressants. These cases were reported post- marketing and are derived from a variety of sources including registries and spontaneous postmarketing reports.

Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers including adalimumab products. These cases have had a very aggressive disease course and have been fatal. The majority of reported TNF blocker cases have occurred in patients with Crohn's disease or ulcerative colitis and the majority were in adolescent and young adult males. Almost all of these patients had received treatment with the immunosuppressants azathioprine or 6-mercaptopurine (6–MP) concomitantly with a TNF blocker at or prior to diagnosis. It is uncertain whether the occurrence of HSTCL is related to use of a TNF blocker or a TNF blocker in combination with these other immunosuppressants. The potential risk with the combination of azathioprine or 6- mercaptopurine and HADLIMA should be carefully considered.
