Clinical Trials Experience

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. Adults Induction The most common adverse reactions occurring in at least 1% of LIALDA- or placebo-treated adult patients with mildly to moderately active ulcerative colitis in two eight-week, randomized, double-blind, placebo-controlled trials (Study 1 and Study 2) are listed in Table 2. Table 2: Adverse Reactions Reported in at least 1% of patients in at least one LIALDA group and greater than placebo in Two Eight-Week, Placebo-Controlled Trials of Induction Therapy (Study 1 and Study 2) in Adults with Mildly to Moderately Active Ulcerative Colitis Adverse Reaction LIALDA 2.4 g once daily LIALDA 4.8 g once daily Placebo (n=177) (n=179) (n=179) Headache 6% 3% <1% Flatulence 4% 3% 3% Liver Function Test Abnormal <1% 2% 1% Alopecia 0 1% 0 Pruritus <1% 1% 1% Pancreatitis occurred in less than 1% of patients during induction in clinical trials and resulted in discontinuation of therapy with LIALDA in patients experiencing this event. Maintenance of Remission A LIALDA dosage of 2.4 g/day, administered as either 1.2 g twice daily or 2.4 g once daily, was evaluated for safety in three maintenance trials in patients with mildly to moderately active ulcerative colitis: a 6-month double-blind, active-controlled study (Study 3) and two 12- to 14-month open-label studies.

The most common adverse reactions with LIALDA in these maintenance trials are listed in Table 3. Table 3: Adverse Reactions Reported in at least 1% of patients in Three Trials of Maintenance of Remission in Adults with Ulcerative Colitis LIALDA 2.4 g/day Administered either as 1.2 g twice daily or 2.4 g once daily (n=1082) Adverse Reaction % Headache 3% Liver function test abnormal 2% Abdominal pain 2% Diarrhea 2% Abdominal distension 1% Abdominal pain upper 1% Dyspepsia 1% Back pain 1% Rash 1% Arthralgia 1% Fatigue 1% Hypertension 1% The following adverse reactions, presented by body system, were reported in less than 1% of LIALDA-treated patients with ulcerative colitis in either induction or maintenance trials: Cardiac Disorder : tachycardia Ear and Labyrinth Disorders : ear pain Gastrointestinal Disorders : abdominal distention, colitis, diarrhea, flatulence, nausea, pancreatitis, rectal polyp, vomiting General Disorders and Administrative Site Disorders : asthenia, face edema, fatigue, pyrexia Investigations : decreased platelet count Musculoskeletal and Connective Tissue Disorders : arthralgia, back pain Nervous System Disorders : dizziness, somnolence, tremor Respiratory, Thoracic and Mediastinal Disorders : pharyngolaryngeal pain Skin and Subcutaneous Tissue Disorders : acne, prurigo, rash, alopecia, pruritus, urticaria Vascular Disorders : hypertension, hypotension Pediatrics LIALDA was evaluated in 105 pediatric patients 5 through 17 years of age with mildly to moderately active ulcerative colitis . The adverse reaction profile was similar to that of adults. The most common adverse reactions reported in at least 5% of pediatric patients treated with LIALDA were: abdominal pain, upper respiratory tract infection, vomiting, anemia, headache, and viral infection.

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of LIALDA or other mesalamine-containing products. 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. Body as a Whole : lupus-like syndrome, drug fever Cardiac Disorders : pericarditis, pericardial effusion, myocarditis Gastrointestinal : cholecystitis, gastritis, gastroenteritis, gastrointestinal bleeding, perforated peptic ulcer Hepatic : jaundice, cholestatic jaundice, hepatitis, liver necrosis, liver failure, hepatotoxicity, Kawasaki-like syndrome including changes in liver enzymes Hematologic : agranulocytosis, aplastic anemia Immune System Disorders : anaphylactic reaction, angioedema Musculoskeletal and Connective Tissue Disorders : myalgia, lupus-like syndrome Neurological/Psychiatric : peripheral neuropathy, Guillain-Barré syndrome, transverse myelitis, intracranial hypertension Renal Disorders : renal failure, interstitial nephritis, nephrogenic diabetes insipidus, nephrolithiasis Urine discoloration occurring ex-vivo caused by contact of mesalamine, including inactive metabolite, with surfaces or water treated with hypochlorite-containing bleach Respiratory, Thoracic and Mediastinal Disorders : interstitial lung disease, hypersensitivity pneumonitis (including interstitial pneumonitis, allergic alveolitis, eosinophilic pneumonitis), pleurisy/pleuritis Skin : psoriasis, pyoderma gangrenosum, erythema nodosum, photosensitivity, SJS/TEN, DRESS, and AGEP Urogenital : reversible oligospermia

Nephrotoxic Agents, Including Non-Steroidal Anti-Inflammatory Drugs

The concurrent use of mesalamine with known nephrotoxic agents, including non-steroidal anti-inflammatory drugs (NSAIDs), may increase the risk of nephrotoxicity. Monitor patients taking nephrotoxic drugs for changes in renal function and mesalamine-related adverse reactions .

Azathioprine and 6-Mercaptopurine

The concurrent use of mesalamine with azathioprine or 6-mercaptopurine and/or any other drugs known to cause myelotoxicity may increase the risk for blood disorders, bone marrow failure, and associated complications. If concomitant use of LIALDA and azathioprine or 6-mercaptopurine cannot be avoided, monitor blood tests, including complete blood cell counts and platelet counts.

Interference with Urinary Normetanephrine Measurements Use of

LIALDA may lead to spuriously elevated test results when measuring urinary normetanephrine by liquid chromatography with electrochemical detection . Consider an alternative, selective assay for normetanephrine.

Pregnancy Risk Summary Published data from meta-analyses, cohort studies, and case series on the use of mesalamine during pregnancy have not reliably informed an association with mesalamine and major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data ). There are adverse effects on maternal and fetal outcomes associated with ulcerative colitis in pregnancy (see Clinical Considerations ). In animal reproduction studies, there were no adverse developmental outcomes with administration of oral mesalamine during organogenesis to pregnant rats and rabbits at doses 1.8 and 2.9 times, respectively, the maximum recommended human dose (see Data ). The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriages in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Clinical Considerations Disease-associated maternal and embryo/fetal risk Published data suggest that increased disease activity is associated with the risk of developing adverse pregnancy outcomes in women with ulcerative colitis. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) infants, and small for gestational age at birth. Data Human Data Published data from meta-analyses, cohort studies, and case series on the use of mesalamine during early pregnancy (first trimester) and throughout pregnancy have not reliably informed an association of mesalamine and major birth defects, miscarriage, or adverse maternal or fetal outcomes.

There is no clear evidence that mesalamine exposure in early pregnancy is associated with an increased risk of major congenital malformations, including cardiac malformations. Published epidemiologic studies have important methodological limitations which hinder interpretation of the data, including inability to control for confounders, such as underlying maternal disease, maternal use of concomitant medications, and missing information on the dose and duration of use for mesalamine products. Animal Data Reproduction studies with mesalamine during organogenesis have been performed in rats at doses up to 1000 mg/kg/day (1.8 times the maximum recommended human dose based on a body surface area comparison) and rabbits at doses up to 800 mg/kg/day (2.9 times the maximum recommended human dose based on a body surface area comparison) and have revealed no evidence of harm to the fetus due to mesalamine.

Pediatric Use The safety and effectiveness of LIALDA have been established for the treatment of mildly to moderately active ulcerative colitis in pediatric patients weighing at least 24 kg. Use of LIALDA in this population is supported by evidence from adequate and well-controlled trials in adults, a multicenter, randomized, double-blind, parallel group trial in 105 pediatric patients 5 to 17 years of age, and additional pharmacokinetic analyses. The safety profile in pediatric patients was similar to that observed in adults . The safety and effectiveness of LIALDA have not been established in patients weighing less than 24 kg.

is contraindicated in patients with known or suspected hypersensitivity to salicylates, aminosalicylates, or to any of the ingredients of LIALDA . Known or suspected hypersensitivity to salicylates or aminosalicylates or to any of the ingredients of LIALDA.

is an aminosalicylate, and symptoms of salicylate toxicity may include nausea, vomiting, abdominal pain, tachypnea, hyperpnea, tinnitus, and neurologic symptoms (headache, dizziness, confusion, seizures). Severe intoxication with salicylates may lead to electrolyte and blood pH imbalance, and potentially end organ (e.g., renal and liver) damage. There is no specific known antidote for mesalamine overdose; however, conventional therapy for salicylate toxicity may be beneficial in the event of acute overdosage and may include gastrointestinal tract decontamination to prevent further absorption. Correct fluid and electrolyte imbalance by the administration of appropriate intravenous therapy and maintain adequate renal function.

LIALDA is a pH-dependent, delayed-release product and this factor should be considered when treating a suspected overdose.
