5 WARNINGS AND PRECAUTIONS

5.6 Risk of Increased Toxicity in the Presence of Impaired Renal Function
  • Patients with moderate to severe renal function impairment may be at greater risk for increased exposure and toxicity. Monitor patients for renal function and systemic toxicity and adjust dosing accordingly. Serious adverse drug reactions including toxic epidermal necrolysis and mucositis were reported in patients with end stage renal disease (ESRD) undergoing dialysis who were administered FOLOTYN therapy. Avoid FOLOTYN use in patients with end stage renal disease including those undergoing dialysis unless the potential benefit justifies the potential risk [see Dosage and Administration (2.2), Adverse Reactions (6.2), Use in Specific Populations (8.7), and Clinical Pharmacology (12.3)].

6 ADVERSE REACTIONS

6.2 Post Marketing Experience
  • 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.

Dermatologic Reactions

  • Toxic epidermal necrolysis, sometimes fatal, has been reported during post-marketing use of FOLOTYN. Fatal cases have been reported following the first dose of FOLOTYN, including when a reduced dose is given, and have been reported in patients with end-stage renal disease undergoing dialysis

8 USE IN SPECIFIC POPULATIONS

8.7 Renal Impairment
  • The safety, efficacy and pharmacokinetics of FOLOTYN have not been evaluated in patients with renal impairment. The risk for toxicity may be greater when administering FOLOTYN to patients with moderate-to-severe impairment due to the contribution of renal excretion (approximately 34%) to the overall clearance of pralatrexate. Serious adverse drug reactions, including TEN and mucositis have been reported in patients with ESRD undergoing dialysis. Monitor patients for renal function and for systemic toxicity due to increased drug exposure and adjust dosing accordingly. Avoid the use of FOLOTYN in patients with end stage renal disease undergoing dialysis unless the potential benefit justifies the potential risk

5 WARNING AND PRECAUTIONS

5.2 Mucositis
  • Treatment with FOLOTYN may cause mucositis. If ≥ Grade 2 mucositis is observed, omit dose and follow guidelines in Section 2.5, Table 1[see Dosage and Administration (2.5)].
5.3 Dermatologic Reactions
  • FOLOTYN has been associated with severe dermatologic reactions, which may result in death. These dermatologic reactions have been reported in clinical studies (14/663 patients [2.1%]) and post marketing experience, and have included skin exfoliation, ulceration, and toxic epidermal necrolysis (TEN). These reactions may be progressive and increase in severity with further treatment, and may involve skin and subcutaneous sites of known lymphoma. Patients with dermatologic reactions should be monitored closely, and if severe, FOLOTYN should be withheld or discontinued.
