FDA Denies 2 Vanda Tasimelteon Petitions
FDA has denied petitions submitted by Vanda Pharmaceuticals on 1/25 and 1/27 asking that the agency revoke approval of ANDAs held by Teva and Apotex for generic forms of Hetlioz (tasimelteon) 20 mg capsules. The petitions claimed the ANDAs do not have the same labeling as the reference-listed drug and thus violated the law’s prohibition against “untrue statement(s) of material fact” and posed safety concerns.
In its denial letter, FDA said it did not find that approval of the generics violated the “same labeling” requirement because the generic container does not include braille or the associated instructions found in the reference-listed drug’s container labeling.
“The omission of braille on the generic tasimelteon products’ container labeling is a permissible difference due to difference in manufacturer,” FDA says. “Additionally, we do not find that omitting the special instructions ‘Dispense in original container’ and ‘Do not cover braille’ on the container labeling for the generic products violates the ‘conditions of use’ requirements, as they are not ‘conditions of use’ for Hetlioz or the generic tasimelteon 20 mg capsule products.”
FDA also did not find that either ANDA included an untrue statement of material fact related to the omission of braille or the associated instructions in their container labeling and said the labeling differences do not raise any safety concerns.
