5 Warnings and Precautions

5.4 Effect on Growth

Additions and/or revisions underlined:

OJEMDA can cause reductions in growth velocity. In FIREFLY-1 [see Adverse Reactions (6.1)], treatment- emergent adverse effects on growth were reported in 46% of 133 patients 18 years of age or younger; 35% were Grade 3 or higher. Reduction in growth velocity resulted in dose interruption in 5% of patients, dose reduction in 2.3% of patients, and permanent discontinuation in 3% of patients. The median change from baseline in height percentile was -14 (z-score change -0.6) for evaluable patients on study for 12 months (N=107) and -20 (z-score change -0.9) for evaluable patients on study for 18 months (N=95).

Growth velocity improved after interruption of treatment with OJEMDA. Among 81 evaluable patients, the median annualized growth velocity ranged from 0.86 to 1.8 cm/year during the 2-year treatment period. Of those, 17 patients had height measurements recorded at least 90 days off-treatment and had a 4.2 cm/year median annualized growth velocity. Routinely monitor patient growth during treatment with OJEMDA [see Adverse Reactions (6), Use in Specific Populations (8.4)].
