Material Changes

  • Related Agreements: The Manufacturing and Supply Agreement, Pharmacovigilance Agreement, Quality Agreement, and Technology Transfer Agreement entered in March 2022 will also terminate on the Termination Date.
  • Reversion of Rights: Upon termination, all rights and licenses granted to Bayer return to Atara, granting the Company full rights to continue clinical development and future commercialization of the programs worldwide.

Outlook, Management Commentary, and Risks

  • Program Status: Atara will continue to support the ongoing ATA2271 Phase 1 study conducted by Memorial Sloan Kettering Cancer Center (MSK).
  • Strategic Shift: The Company intends to lead IND-enabling studies and process development for ATA3271 but plans to postpone the anticipated IND for ATA3271 beyond the fourth quarter of 2022.
  • Resource Allocation: The postponement is due to the allocation of resources to other programs, specifically ATA188, tab-cel, and ATA3219, while the Company re-assesses its strategy for the mesothelin CAR T programs.
  • Risks: The filing includes standard forward-looking statement disclaimers, noting that actual outcomes may differ due to risks discussed in the Company's 2021 Form 10-K.

Investor Verification Checklist

  • Verify the specific terms of the transition negotiations regarding the transfer of clinical trial data and regulatory documentation.
  • Confirm the updated timeline for the ATA3271 IND application given the stated postponement beyond Q4 2022.
  • Review the impact of resource reallocation on the progress of the ATA188, tab-cel, and ATA3219 programs.
