One patient with hairy cell leukemia treated with NIPENT during another clinical study developed unilateral uveitis with vision loss.
Nineteen (5%) patients withdrew from the Phase 3 SWOG 8691 study because of adverse events; 9 during initial NIPENT treatment, 4 during NIPENT crossover, 5 during initial IFN treatment, and 1 during both initial IFN treatment and NIPENT crossover. In the Phase 2 studies in IFN-refractory hairy cell leukemia, 11% of patients withdrew from treatment with NIPENT due to an adverse event.
