LIALDA tablets are indicated for the induction of remission in patients with active, mild to moderate ulcerative colitis. Effectiveness of LIALDA beyond 8 weeks has not been established.
The recommended dosage for the induction of remission in adult patients with active, mild to moderate ulcerative colitis is two to four 1.2g tablets to be taken once daily with meal for a total daily dose of 2.4g or 4.8g.
1.2g tablets
LIALDA is contraindicated in patients with hypersensitivity to salicylates (including mesalamine) or to any of the components of LIALDA.
Organic or functional obstruction in the upper gastrointestinal tract may delay onset of action of LIALDA.
The majority of patients who are intolerant or hypersensitive to sulfasalazine can take mesalamine medications without risk of similar reactions. However, caution should be exercised when treating patients allergic to sulfasalazine.
Mesalamine-induced cardiac hypersensitivity reactions (myocarditis and pericarditis) have been reported with LIALDA and other mesalamine medications. Caution should be taken in prescribing this medicine to patients with conditions predisposing them to the development of myocarditis or pericarditis.
Mesalamine has been associated with an acute intolerance syndrome that may be difficult to distinguish from a flare of inflammatory bowel disease. Although the exact frequency of occurrence has not been determined, it has occurred in 3% of patients in controlled clinical trials of mesalamine or sulfasalazine. Symptoms include cramping, acute abdominal pain and bloody diarrhea, sometimes fever, headache and rash. If acute intolerance syndrome is suspected, prompt withdrawal is required.
Reports of renal impairment, including minimal change nephropathy, and acute or chronic interstitial nephritis have been associated with mesalamine medications and pro-drugs of mesalamine. For any patient with known renal dysfunction, caution should be exercised and LIALDA should be used only if the benefits outweigh the risks. It is recommended that all patients have an evaluation of renal function prior to initiation of therapy and periodically while on treatment. [See Drug Interactions (7.1) and Animal Toxicology (13.2)]
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.
LIALDA tablets have been evaluated in 655 ulcerative colitis patients in controlled and open-label trials.
In two 8-week placebo-controlled clinical trials involving 535 ulcerative colitis patients, 356 received 2.4g/day or 4.8g/day LIALDA tablets and 179 received placebo. More treatment emergent adverse events occurred in the placebo group (119) than in each of the LIALDA treatment groups (109 in 2.4g/day, 92 in 4.8g/day). A lower percentage of LIALDA patients discontinued therapy due to adverse events compared to placebo (2.2% vs. 7.3%). The most frequent adverse event leading to discontinuation from LIALDA therapy was exacerbation of ulcerative colitis (0.8%).
The majority of adverse events in the double blind, placebo-controlled trials were mild or moderate in severity. The percentage of patients with severe adverse events was higher in the placebo group (6.1% in placebo; 1.1% in 2.4g/day; 2.2% in 4.8g/day). The most common severe adverse events were gastrointestinal disorders which were mainly symptoms associated with ulcerative colitis. Pancreatitis occurred in less than 1% of patients during clinical trials and resulted in discontinuation of therapy with LIALDA in patients experiencing this event.
Overall, the percentage of patients who experienced any adverse event was similar across treatment groups. Treatment related adverse events occurring in LIALDA or placebo groups at a frequency of at least 1% in two Phase 3, 8-week, double blind, placebo-controlled trials are listed in Table 1. The most common treatment related adverse events with LIALDA 2.4g/day and 4.8g/day were headache (5.6% and 3.4%, respectively) and flatulence (4% and 2.8%, respectively).

Pooled Safety Analysis
In a pooled safety analysis of patients with active ulcerative colitis who participated in two Phase 2 trials and three Phase 3 trials, (four of the five studies were in acute disease, the fifth study was a long-term safety extension study with subjects enrolled from the two 8-week placebo-controlled pivotal studies) the majority of subjects did not experience treatment emergent adverse events associated with LIALDA. Of the events reported, the majority were transient, and mild or moderate in severity.
In the pooled safety analysis of 664 patients with active ulcerative colitis who participated in controlled clinical studies, 356 received 2.4g/day or 4.8g/day LIALDA tablets and 179 received placebo in the pivotal, 8-week double-blind placebo-controlled clinical studies. A total of 558 subjects were enrolled into a long-term safety extension study. Of these 558 patients, 363 (79.1%) received LIALDA for >48 weeks.
In the pooled safety analysis, the percentage of patients who experienced any adverse event was similar across treatment groups. Treatment related adverse events occurring in LIALDA or placebo groups at a frequency of at least 1% in two Phase 3, 8-week, double blind, placebo-controlled trials are listed in Table 1.
The overall incidence of serious adverse events with LIALDA in the pooled safety population compared to placebo was: 5% of LIALDA subjects (33/664) experienced serious adverse events, compared with 1.4% of subjects (9/664) in the placebo-controlled pool. The most common severe adverse events were gastrointestinal disorders which were mainly symptoms associated with ulcerative colitis. The most common adverse reactions were headache, abdominal pain, and nausea.
In the pooled safety analysis, the following treatment-related adverse events, presented by body system, were experienced by at least 1% of the LIALDA-treated ulcerative colitis patients in controlled trials.
Vascular Disorder: hypertension
Skin and Subcutaneous Tissue Disorders: pruritus, rash
Gastrointestinal Disorders: abdominal distention, abdominal pain, diarrhea, dyspepsia, flatulence, nausea, vomiting
Investigations: liver-function test abnormal (e.g. ALT; AST; bilirubin)
Musculoskeletal and Connective Tissue Disorders: arthralgia associated with myalgia, back pain
Nervous System Disorder: headache
General Disorders and Administrative Site Disorders: asthenia, pyrexia
In the pooled safety analysis, the following treatment-related adverse events, presented by body system, were experienced by less than 1% of the LIALDA-treated ulcerative colitis patients in controlled trials.
Blood and Lymphatic System Disorder: thrombocytopenia
Cardiac Disorder: tachycardia
Vascular Disorder: hypotension
Skin and Subcutaneous Tissue Disorders: acne, alopecia, urticaria
Gastrointestinal Disorders: pancreatitis, rectal polyp
Nervous System Disorders: dizziness, somnolence, tremor
Respiratory, Thoracic and Mediastinal Disorders: pharyngolaryngeal pain

Ear and Labyrinth Disorder: ear pain
The following adverse reactions have been identified during post-approval use of Lialda in clinical practice. 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.
Cardiac Disorders: myocarditic, pericarditis
Hepatobiliary Disorders: hepatitis
Renal Disorders: interstitial nephritis
Respiratory, Thoracic and Mediastinal Disorders: hypersensitivity pneumonitis (including interstitial pneumonitis, allergic alveolitis, eosinophilic pneumonitis)
No investigations of interaction between LIALDA and other drugs have been performed. However, the following are reports of interactions between mesalamine medications and other drugs.
The concurrent use of mesalamine with known nephrotoxic agents, including non-steroidal anti-inflammatory drugs (NSAIDs) may increase the risk of renal reactions.
The concurrent use of mesalamine can increase the potential for blood disorders.
Teratogenic Effects: Pregnancy Category B
There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Mesalamine is known to cross the placental barrier. [See Carcinogenesis, Mutagenesis and Impairment of Fertility 13.1]
Low concentrations of mesalamine and higher concentrations of its N-acetyl metabolite have been detected in human breast milk. While there is limited experience of lactating women using mesalamine, caution should be exercised if LIALDA is administered to a nursing mother, and used only if the benefits outweigh the risks.
Safety and effectiveness of LIALDA tablets in pediatric patients who are less than 18 years of age have not been studied.
Clinical trials of LIADLA did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In a pharmacokinetic study, systemic exposure to mesalamine increased by up to 2-fold in elderly subjects (>65 years) compared with younger adult subjects (18-35 years) after a 4.8g single dose of LIALDA. Systemic exposures in individual subjects were inversely correlated with renal function as assessed by estimated creatinine clearance. In general, dose selection for an elderly patient should be cautions, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concurrent disease or other drug therapy.
No information is available on patients with hepatic impairment, and therefore, caution is recommended in these patients.
No consistent trend on gender effect was observed in the clinical trials.
No information is available which examines LIALDA in different races.
LIALDA is an aminosalicylate, and symptoms of salicylate toxicity may include tinnitus, vertigo, headache, confusion, drowsiness, sweating, hyperventilation, vomiting, and diarrhea. Severe intoxication may lead to disruption of electrolyte balance and blood-pH, hyperthermia, and dehydration.
Conventional therapy for salicylate toxicity may be beneficial in the event of acute overdosage. Fluid and electrolyte imbalance should be corrected by the administration of appropriate intravenous therapy. Adequate renal function should be maintained.
Each LIALDA delayed release tablet for oral administration contains 1.2g 5-aminosalicylic acid (5-ASA; mesalamine), an anti-inflammatory agent. Mesalamine also has the chemical name 5-amino-2-hydroxybenzoic acid and its structural formula is:
Molecular formula: C7H7NO3
Molecular weight: 153.14
The LIALDA tablet contains a core of mesalamine (5-aminosalicylic acid), 1.2g, formulated with MMX Multi Matrix System® technology. MMX® uses a gastro-resistant film of methacrylic acid copolymers, Type A and Type B, which are designed to delay the initial release of mesalamine until exposure to approximately pH 7 and above. A consistent and sustained release was observed across the pH range 6.8 to 7.2. The MMX® technology also uses a matrix of lipophilic and hydrophilic excipients which facilitate the delayed and extended delivery of effective concentrations of mesalamine through the entire colon with limited systemic absorption.
The inactive ingredients of LIALDA tablets are sodium carboxymethylcellulose, carnauba wax, stearic acid, silica (colloidal hydrated), sodium starch glycolate (type A), talc, magnesium stearate, methacrylic acid copolymer types A and B, triethylcitrate, titanium dioxide, red ferric oxide and polyethyleneglycol 6000.
The mechanism of action of mesalamine is not fully understood, but appears to have a topical anti-inflammatory effect on the colonic epithelial cells. Mucosal production of arachidonic acid metabolites, both through the cyclooxygenase and lipoxygenase pathways, is increased in patients with chronic inflammatory bowel disease, and it is possible that mesalamine diminishes inflammation by blocking cyclooxygenase and inhibiting prostaglandin production in the colon.
Mesalamine has the potential to inhibit the activation of nuclear factor kappa B (NFkB) and consequently the production of key pro-inflammatory cytokines. More recently, it has been proposed that impairment of PPAR-y nuclear receptors (y-form of peroxisome proliferator-activated receptors) may be implicated in ulcerative colitis. PPAR-y receptor agonists have shown efficacy in ulcerative colitis and evidence has been accumulating that the mechanism of action of mesalamine may be mediated by PPAR-y receptors.
The pharmacodynamic actions of mesalamine occur in the colonic/rectal mucosae local to the delivery of drug from LIALDA into the lumen. There is information suggesting that severity of colonic inflammation in ulcerative colitis patients treated with mesalamine is inversely correlated with mucosal concentrations of mesalamine. However, plasma concentrations representing systemically absorbed mesalamine are not believed to contribute extensively to efficacy.
Absorption
The total absorption of mesalamine from LIALDA 2.4g or 4.8g given once daily for 14 days to healthy volunteers was found to be approximately 21-22% of the administered dose.
Gamma-scintigraphy studies have shown that a single dose of LIALDA 1.2g (one tablet) passed intact through the upper gastrointestinal tract of fasted healthy volunteers. Scintigraphic images showed a trail of radio-labeled tracer in the colon, suggesting that mesalamine had distributed throughout this region of the gastrointestinal tract. Complete disintegration of LIALDA and complete release of mesalamine occurred after approximately 17.4 hours.
In a single dose study, LIALDA 1.2g, 2.4g and 4.8g were administered in the fasted state to healthy subjects. Plasma concentrations of mesalamine were detectable after 2 hours and reached a maximum by 9-12 hours on average for the doses studied. The pharmacokinetic parameters are highly variable among subjects (Table 2). Mesalamine systemic exposure in terms of area under the plasma concentration-time curve (AUC) was slightly more than dose proportional between 1.2g and 4.8g LIALDA. Maximum plasma concentrations (Cmax) of mesalamine increased approximately dose proportionately between 1.2g and 2.4g and sub-proportionately between 2.4g and 4.8g LIALDA, with the dose normalized value at 4.8g representing, on average, 74% of that at 2.4g based on geometric means.

Administration of a single dose of LIALDA 4.8g with a high fat meal resulted in further delay in absorption and plasma concentrations of mesalamine were detectable 4 hours following dosing. However, high fat meal increased systemic exposure of mesalamine (mean Cmax: 91%; mean AUC: 16%) compared to results in the fasted state. LIALDA was administered with food in the Phase 3 trials.
In a single and multiple dose pharmacokinetic study of LIALDA 2.4g or 4.8g was administered once daily with standard meals to 28 healthy volunteers per dose group. Plasma concentrations of mesalamine were detectable after 4 hours and were maximal by 8 hours after the single dose. Steady state was achieved generally by 2 days after dosing. Mean AUC at steady state was only modestly greater (1.1- to 1.4-fold) than predictable from single dose pharmacokinetics.
In a single dose pharmacokinetic study of LIALDA, 4.8g was administered in the fasted state to 71 healthy male and female volunteers (36 young (18-35yrs); 24 elderly (65-75yrs); 11 elderly (>75yrs)). Increased age resulted in increased systemic exposure (up to 2-fold, based on AUC0-t, AUC0-∞ and Cmax) to mesalamine and its metabolite N-acetyl-5-aminosalicylic acid but did not affect the percentage of mesalamine absorbed. Increased age resulted in a slower apparent elimination of mesalamine, though there was high between-subject variability. Systemic exposures in individual subjects were inversely correlated with renal function as assessed by estimated creatinine clearance.

Distribution
Mesalamine is approximately 43% bound to plasma proteins at the concentration of 2.5 μg/mL.
Metabolism
The only major metabolite of mesalamine (5-aminosalicylic acid) is N-acetyl-5-aminosalicylic acid, which is pharmacologically inactive. Its formation is brought about by N-acetyltransferase (NAT) activity in the liver and intestinal mucosa cells principally by NAT-1. Although this enzyme is known to be subject to genetic polymorphism, NAT-1 genotypes have been shown not to be predictive of mesalamine efficacy or toxicity.
Elimination
Elimination of mesalamine is mainly via the renal route following metabolism to N-acetyl-5-aminosalicylic acid (acetylation). However, there is also limited excretion of the parent drug in urine. Of the approximately 21-22% of the dose absorbed, less than 8% of the dose was excreted unchanged in the urine at steady state after 24 hours, compared with greater than 13% for N-acetyl-5-aminosalicylic acid. The apparent terminal half-lives for mesalamine and its major metabolite after administration of LIALDA 2.4g and 4.8g were, on average, 7-9 hours and 8-12 hours, respectively.
Carcinogenesis
In a 104-week dietary carcinogenicity study in CD-1 mice, mesalamine at doses up to 2500 mg/kg/day was not tumorigenic. This dose is 2.2 times the maximum recommended human dose (based on a body surface area comparison) of LIALDA. Furthermore, in a 104-week dietary carcinogenicity study in Wistar rats, mesalamine up to a dose of 800 mg/kg/day was not tumorigenic. This dose is 1.4 times the recommended human dose (based on a body surface area comparison) of LIALDA.
Mutagenesis
No evidence of mutagenicity was observed in an in vitro Ames test or an in vivo mouse micronucleus test.
Impairment of Fertility
No effects on fertility or reproductive performance were observed in male or female rats at oral doses of mesalamine up to 400 mg/kg/day (0.7 times the maximum recommended human dose based on a body surface area comparison). Semen abnormalities and infertility in men, which have been reported in association with sulfasalazine, have not been seen with other mesalamine products during controlled clinical trials.
Reproduction studies with mesalamine 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 impaired fertility or harm to the fetus due to mesalamine.
In animal studies with mesalamine, a 13-week oral toxicity study in mice and 13-week and 52-week oral toxicity studies in rats and cynomolgus monkeys have shown the kidney to be the major target organ of mesalamine toxicity. Oral daily doses of 2400 mg/kg in mice and 1150 mg/kg in rats produced renal lesions including granular and hyaline casts, tubular degeneration, tubular dilation, renal infarct, papillary necrosis, tubular necrosis, and interstitial nephritis. In cynomolgus monkeys, oral daily doses of 250 mg/kg or higher produced nephrosis, papillary edema, and interstitial fibrosis.
Two similarly designed, randomized, double blind, placebo-controlled trials were conducted in 517 adult patients with active, mild to moderate ulcerative colitis. The study population was primarily Caucasian (80%), had a mean age of 42 years (6% age 65 years or older), and was approximately 50% male. Both studies used LIALDA doses of 2.4g/day and 4.8g/day administered once daily for 8 weeks except for the 2.4g/day group in Study 1, which was given in two divided doses (1.2g BID). The primary efficacy end-point in both trials was to compare the percentage of patients in remission after 8 weeks of treatment for the LIALDA treatment groups vs placebo. Remission was defined as an Ulcerative Colitis Disease Activity Index (UC-DAI) of ≤ 1, with scores of zero for rectal bleeding and for stool frequency, and a sigmoidoscopy score reduction of 1 point or more from baseline.
In both studies, the LIALDA doses of 2.4g/day and 4.8g/day demonstrated superiority over placebo in the primary efficacy endpoint (Table 4). Both LIALDA doses also provided consistent benefit in secondary efficacy parameters, including clinical improvement, treatment failure, clinical remission, and sigmoidoscopic improvement. LIALDA 2.4g/day and 4.8g/day had similar efficacy profiles.
