NIPENT

CLINICAL STUDIES The following table provides efficacy results for 4 groups (columns) of patients with hairy cell leukemia: patients who initially received NIPENT, patients who initially received alpha-interferon (IFN), and 2 different groups of patients who received NIPENT after proving to be refractory to, or intolerant of IFN therapy. The first 2 groups represent treatment results from the SWOG 8691 study, a large multicenter study comparing NIPENT and IFN in untreated (frontline) patients with confirmed hairy cell leukemia. The third group represents evaluable patients from the SWOG study ...

ADVERSE REACTIONS Most patients treated for hairy cell leukemia in the five NCI-sponsored Phase 2 studies and the Phase 3 SWOG study experienced an adverse event. The following table lists the most frequently occurring adverse events in patients treated with NIPENT (both frontline and IFN-refractory patients) compared with IFN (frontline only), regardless of drug association. The drug association of some adverse events is uncertain as they may be associated with the disease itself (e.g., infecti...

CONTRAINDICATIONS NIPENT is contraindicated: In patients who have demonstrated hypersensitivity to NIPENT.

Drug Interactions Allopurinol and NIPENT are both associated with skin rashes. Based on clinical studies in 25 refractory patients who received both NIPENT and allopurinol, the combined use of NIPENT and allopurinol did not appear to produce a higher incidence of skin rashes than observed with NIPENT alone. There has been a report of one patient who received both drugs and experienced a hypersensi...
