5 Warnings and Precautions

Newly added subsection:

5.6 Risk of P. vivax Malaria Recurrence

Lack of efficacy in reducing P. vivax malaria recurrence in patients treated with KRINTAFEL combined with an artemisinin-containing antimalarial was seen in a clinical trial (NCT02802501). In this double-blind, randomized, placebo-controlled trial in which all patients with P. vivax malaria were treated with dihydroartemisinin/piperaquine (not approved artemisinin-containing antimalarial) and were coadministered KRINTAFEL, primaquine, or placebo, lack of efficacy (recurrence rates at 6 months following treatment) was seen in patients treated with KRINTAFEL.

Concomitant administration of KRINTAFEL with antimalarials other than chloroquine is not recommended.
