Rhea-AI Filing Summary

Rocket Pharmaceuticals, Inc. announced it voluntarily withdrew its U.S. Biologics License Application for mozafancogene autotemcel (RP-L102 / Fanskya) on October 3, 2025. The company stopped new internal investment in RP-L102 in July 2025 and also withdrew its MAA with the EMA in July 2025, citing a corporate prioritization to focus resources on programs with clearer regulatory and commercial paths. Rocket said the withdrawal reflects business and strategic considerations and does not reflect safety or efficacy concerns; it stated that data to date show RP-L102 has been generally well tolerated with no significant safety signals. The company will consider external partnerships and reserves the ability to re-engage regulators later if a sustainable pathway emerges.

Positive

  • Data to date show RP-L102 has been generally well tolerated with no significant safety signals
  • Withdrawal preserves ability to re-engage regulators if a future partnership or pathway is identified
  • Company will consider external partnerships that could enable advancement without internal investment

Negative

  • Voluntary withdrawal of the U.S. BLA on October 3, 2025 for RP-L102
  • Cessation of new internal investment in RP-L102 in July 2025
  • Withdrawal of the MAA with the EMA in July 2025, removing near-term regulatory filings for the program

Insights

Company withdrew its U.S. BLA for RP-L102 to refocus resources while preserving future options.

The withdrawal of the BLA on October 3, 2025 and the earlier MAA withdrawal in July 2025 indicate a strategic reallocation of capital toward programs with clearer regulatory and commercial prospects. This is a business-driven move rather than a regulatory safety action, as Rocket explicitly states there are no significant safety signals in the RP-L102 data.

Maintaining the option to seek external partnerships preserves the program's potential pathway forward without ongoing internal spend; that keeps the asset off the companys active development budget while leaving regulatory engagement possible if a partner supports advancement.

Item 8.01.
Other Events.

On October 3, 2025, Rocket Pharmaceuticals, Inc. (“Rocket” or the “Company”) reported that it has voluntarily withdrawn its Biologics License Application (“BLA”) to the U.S. Food and Drug Administration (“FDA”) for mozafancogene autotemcel (also known as “Fanskya,” “Fanca-cel,” or “RP-L102”), an investigational gene therapy for the treatment of Fanconi Anemia (“FA”).

This decision follows the Company’s previously announced corporate prioritization, under which Rocket is focusing its resources on programs with the clearest regulatory and commercial pathways. As a result, Rocket ceased new internal investment in RP-L102 in July 2025, subsequently withdrew its Marketing Authorization Application (“MAA”) with the European Medicines Agency in July 2025, and has now withdrawn its U.S. BLA.

The Company’s decision to withdraw the BLA is based on business and strategic considerations and does not reflect concerns regarding the safety or efficacy profile of RP-L102. Data generated to date continue to support that RP-L102 has been generally well tolerated, with no significant safety signals observed, and a risk-benefit profile that appears favorable.

The Company will consider external partnership opportunities that could potentially enable the advancement of RP-L102 in the future. Withdrawal of the BLA preserves Rocket’s ability to re-engage with regulators at a later date should there be an appropriate strategic or partnership pathway to sustainably progress the program
