About elivaldogene autotemcel (eli-cel, Lenti-D(tm) gene therapy)

In July 2020, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) granted an accelerated assessment to eli-cel gene therapy for cerebral adrenoleukodystrophy (CALD). bluebird bio is currently on track to submit the Marketing Authorization Application (MAA) in the EU for eli-cel for CALD by year-end 2020, and the Biologics License Application (BLA) in the U.S. in mid-2021.

bluebird bio is currently enrolling patients for a Phase 3 study (ALD-104) designed to assess the efficacy and safety of eli-cel after myeloablative conditioning using busulfan and fludarabine in patients with CALD. Contact clinicaltrials@bluebirdbio.com for more information and a list of study sites.

Additionally, bluebird bio is conducting a long-term safety and efficacy follow-up study (LTF-304) for patients who have been treated with eli-cel for CALD and completed two years of follow-up in bluebird bio-sponsored studies.

The Phase 2/3 Starbeam study (ALD-102) has completed enrollment. For more information about the ALD-102 study visit: www.bluebirdbio.com/our-science/clinical-trials or clinicaltrials.gov and use identifier NCT01896102.

Adrenoleukodystrophy (ALD) is a rare, X-linked metabolic disorder that is estimated to affect one in 21,000 male newborns worldwide. Approximately 40 percent of boys with ALD will develop CALD, the most severe form of ALD. CALD is a progressive neurogenerative disease that involves breakdown of myelin, the protective sheath of the nerve cells in the brain that are responsible for thinking and muscle control. Symptoms of CALD usually occur in early childhood and progress rapidly, if untreated, leading to severe loss of neurologic function, and eventual death, in most patients.

The European Medicines Agency (EMA) accepted eli-cel gene therapy for the treatment of CALD into its Priorities Medicines scheme (PRIME) in July 2018, and previously granted Orphan Medicinal Product designation to eli-cel.

The U.S. Food and Drug Administration (FDA) granted eli-cel Orphan Drug status, Rare Pediatric Disease designation, and Breakthrough Therapy designation for the treatment of CALD.

Eli-cel is not approved for any indication in any geography.

About idecabtagene vicleucel (ide-cel; bb2121)

Ide-cel is a B-cell maturation antigen (BCMA)-directed genetically modified autologous chimeric antigen receptor (CAR) T cell immunotherapy. The ide-cel CAR is comprised of a murine extracellular single-chain variable fragment (scFv) specific for recognizing BCMA, attached to a human CD8 ? hinge and transmembrane domain fused to the T cell cytoplasmic signaling domains of CD137 4-1BB and CD3-? chain, in tandem. Ide-cel recognizes and binds to BCMA on the surface of multiple myeloma cells leading to CAR T cell proliferation, cytokine secretion, and subsequent cytolytic killing of BCMA-expressing cells.

In addition to the pivotal KarMMa trial evaluating ide-cel in patients with relapsed and refractory multiple myeloma, bluebird bio and Bristol Myers Squibb's broad clinical development program for ide-cel includes clinical studies (KarMMa-2, KarMMa-3, KarMMa-4) in earlier lines of treatment for patients with multiple myeloma, including newly diagnosed multiple myeloma. For more information visit clinicaltrials.gov.

In July 2020, Bristol Myers Squibb (BMS) and bluebird bio submitted the Biologics License Application for ide-cel to the U.S. Food and Drug Administration for the treatment of adult patients with multiple myeloma who have received at least three prior therapies, including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 antibody. Ide-cel is the first CAR T cell therapy submitted for regulatory review to target BCMA and for multiple myeloma.

Ide-cel was granted Breakthrough Therapy Designation (BTD) by the U.S. Food and Drug Administration (FDA) and PRIority Medicines (PRIME) designation, as well as Accelerated Assessment status, by the European Medicines Agency for relapsed and refractory multiple myeloma.

Ide-cel is being developed as part of a Co-Development, Co-Promotion and Profit Share Agreement between BMS and bluebird bio.

Ide-cel is not approved for any indication in any geography.
