A total of 148 patients received at least 1 dose of 10 mg lenalidomide in the del 5q MDS clinical study. At least one adverse event was reported in all of the 148 patients who were treated with the 10 mg starting dose of REVLIMID^Ã? (lenalidomide). The most frequently reported adverse events were related to blood and lymphatic system disorders, skin and subcutaneous tissue disorders, gastrointestinal disorders, and general disorders and administrative site conditions. (See PRECAUTIONS)

Thrombocytopenia (61.5%; 91/148) and neutropenia (58.8%; 87/148) were the most frequently reported adverse events observed. The next most common adverse events observed were diarrhea (48.6%; 72/148), pruritis (41.9%; 62/148), rash (35.8%; 53/148) and fatigue (31.1%; 46/148). Table 4 summarizes the adverse events that were reported in ≥ 5% of the REVLIMID^Ã? (lenalidomide) treated patients in the del 5q MDS clinical study. Table 5 summarizes the most frequently observed Grade 3 and Grade 4 adverse reactions regardless of relationship to treatment with REVLIMID^Ã? (lenalidomide). In the single-arm studies conducted, it is often not possible to distinguish adverse events that are drug-related and those that reflect the patients underlying disease.

Data were evaluated from 691 patients in two studies who received at least one dose of REVLIMID^Ã? (lenalidomide)/dexamethasone (346 patients) or placebo/dexamethasone (345 patients). In the REVLIMID^Ã? (lenalidomide) /dexamethasone treatment group, 151 patients (45%) underwent at least one dose interruption with or without a dose reduction of REVLIMID^Ã? (lenalidomide) compared to 21% in the placebo/dexamethasone treatment group. Of these patients who had one dose interruption with or without a dose reduction, 50% in the REVLIMID^Ã? (lenalidomide) /dexamethasone treatment group underwent at least one additional dose interruption with or without a dose reduction compared to 21% in the placebo/dexamethasone treatment group. Most adverse events and Grade 3/4 adverse events were more frequent in patients who received the combination of REVLIMID^Ã?(lenalidomide)/dexamethasone compared to placebo/dexamethasone.

Table 6 summarizes the number and percentage of patients with Grade 1-4 adverse events reported in ≥ 10% of patients in either treatment group in Studies 1 and 2.

Table 7 summarizes the Grade 3/4 adverse events reported in ≥ 2% of patients in either treatment group in Studies 1 and 2.

Results from human in vitro metabolism studies and nonclinical studies show that REVLIMID^Ã? (lenalidomide) is neither metabolized by nor inhibits or induces the cytochrome P450 pathway suggesting that lenalidomide is not likely to cause or be subject to P450-based metabolic drug interactions in man.

Co-administration of multiple doses of 10 mg of lenalidomide had no effect on the single dose pharmacokinetics of R- and S- warfarin. Co-administration of single 25-mg dose warfarin had no effect on the pharmacokinetics of total lenalidomide. Expected changes in laboratory assessments of PT and INR were observed after warfarin administration, but these changes were not affected by concomitant lenalidomide administration.

When digoxin was co-administered with lenalidomide the digoxin AUC was not significantly different, however, the digoxin C_max was increased by 14%. Periodic monitoring of digoxin plasma levels, in accordance with clinical judgment and based on standard clinical practice in patients receiving this medication, is recommended during administration of lenalidomide.
