# SUPPLEMENTARY INFORMATION:

On June 16, 2011, FDA approved an additional indication for Celgene's new drug application (NDA) 22393 for ISTODAX (romidepsin) for injection, 10 mg, specifically for treatment of peripheral T-cell lymphoma (PTCL) in adult patients who have received at least one prior therapy, under the Agency's accelerated approval regulations, 21 CFR part 314, subpart H. The accelerated approval of Celgene's ISTODAX (romidepsin) for injection for PTCL included a required postmarketing clinical trial intended to verify the clinical benefit of romidepsin (the Ro-CHOP study) for PTCL.

On March 13, 2020, FDA approved Teva's NDA 208574 for Romidepsin injection, 10 mg/2 milliliter, for treatment of peripheral T-cell lymphoma (PTCL) in adult patients who have received at least one prior therapy, under the Agency's accelerated approval regulations, 21 CFR part 314, subpart H. The accelerated approval of Teva's Romidepsin injection for PTCL also included a required postmarketing clinical trial intended to verify the clinical benefit of romidepsin for PTCL. Teva's Romidepsin injection product was approved under the 505(b)(2) approval pathway, and the listed drug relied upon is Celgene's NDA 22393, ISTODAX (romidepsin) for injection.

On August 6, 2020, Celgene submitted high level results from the Ro-CHOP study to FDA, which indicated the study failed to meet its primary endpoint of progression free survival. On May 14, 2021, Celgene informed FDA that after careful consideration, Celgene decided to voluntarily withdraw the PTCL indication from ISTODAX (romidepsin) for injection.

On June 17, 2021, Celgene submitted a supplemental NDA proposing to remove the PTCL indication. On July 14, 2021, Celgene submitted a letter asking FDA to withdraw approval of the PTCL indication pursuant to § 314.150(d) (21 CFR 314.150(d)) and waiving its opportunity for a hearing.

On August 27, 2021, Teva submitted a labeling supplement proposing to remove the PTCL indication. On September 12, 2021, the Agency requested Teva voluntarily request withdraw of the PTCL indication pursuant to § 314.150(d) and waive its opportunity for a hearing. On September 14, 2021, Teva amended its supplement by submitting a cover letter requesting withdrawal of approval of the PTCL indication pursuant to § 314.150(d) and waiving its opportunity for a hearing.

Therefore, under § 314.150(d), approval of the PTCL indications for ISTODAX (romidepsin) for injection, and Romidepsin injection, is withdrawn effective May 9, 2022. Withdrawal of approval of the PTCL indication does not affect any other approved indication(s) for ISTODAX (romidepsin) for injection or Romidepsin injection.

Dated: May 4, 2022.
