Taysha Gene Therapies Provides Update on Deprioritized Pipeline Programs

DALLAS, Feb. 15, 2024 (GLOBE NEWSWIRE) -- Taysha Gene Therapies, Inc. (Nasdaq: TSHA) (“Taysha” or “the Company”), a clinical-stage gene therapy company focused on developing and commercializing AAV-based gene therapies for the treatment of monogenic diseases of the central nervous system (CNS), today provided an update on its deprioritized pipeline programs as part of an ongoing effort to help support their further potential development.

Taysha has been working to find ways to advance its deprioritized programs. On November 13, 2023, Taysha terminated its existing loan and security agreement and entered into a new loan and security agreement that provides consent to allow the Company to transfer intellectual property (IP) for several deprioritized programs to third parties in a more efficient manner. The Company’s new loan and security agreement also extended its cash runway into 2026.

Recent progress on previously deprioritized pipeline programs includes:

  • TSHA-120: The Company initiated the transfer of the United States Food and Drug Administration Investigational New Drug (IND) application and investigational clinical trial material for TSHA-120 in giant axonal neuropathy (GAN) to clinical trial collaborator National Institute of Neurological Disorders and Stroke (NINDS), creating an opportunity for continued clinical evaluation of TSHA-120 in GAN. Additionally, the Company entered discussions with the originating advocacy organization regarding TSHA-120 in an effort to transfer rights back to the advocacy organization to move the program forward.
  • TSHA-101: The Company transferred rights back to Queen’s University (Queen’s) for TSHA-101 in GM2 gangliosidosis, resulting in Queen’s regaining exclusive IP to the program.
  • TSHA-104 and TSHA-112: The Company transferred rights back to the originating institution for select programs, including TSHA-104 in SURF1-associated Leigh syndrome and TSHA-112 in APBD.
  • TSHA-118: The Company provided investigational clinical trial material for TSHA-118 in CLN1 to support an individual-patient investigator-initiated IND request from RUSH University Medical Center for the treatment of a patient with CLN1 disease.

“Today’s announcement demonstrates meaningful progress to advance important development work for several deprioritized programs. Creating options for these programs has been a focus since the Company completed a management change in December 2022, and the new loan and security agreement afforded the flexibility to implement certain opportunities,” said Sean P. Nolan, Chairman and Chief Executive Officer of Taysha. “As we continue to focus on advancing our lead TSHA-102 program for the treatment of Rett syndrome, we are pleased that we can ensure these programs are provided to the right advocates, clinicians and scientific experts who can potentially move these programs forward for the benefit of patients.”

The Company continues to explore potential partnerships and opportunities for its other deprioritized programs to help support their further potential development.
