Mission Therapeutics Discontinues Preclinical Operations to Focus on Advanced Clinical Programs

• Mission Therapeutics announces strategic shift by closing its UK preclinical laboratory operations while maintaining sufficient cash runway through 2026.

• The company will concentrate on two clinical-stage USP30 inhibitors: MTX652 for acute kidney injury and heart failure, and MTX325 for Parkinson's disease.

• Mission maintains its strategic collaboration with AbbVie for Alzheimer's disease programs, following a previous $20 million milestone payment achievement.

Mission Therapeutics has announced a strategic reorganization, discontinuing its preclinical operations and closing its United Kingdom laboratory to focus resources on its advanced clinical programs. The company confirms its strong financial position with a cash runway extending well into 2026.

Strategic Focus on Clinical-Stage Assets

The company's pipeline now centers on two promising clinical candidates targeting USP30, a deubiquitylating enzyme (DUB) that plays a crucial role in mitochondrial quality control. These enzymes have emerged as attractive therapeutic targets due to their involvement in multiple disease pathways.
MTX652, the company's lead asset, recently achieved a significant milestone by securing FDA clearance for Phase II studies in acute kidney injury in December 2023. The drug demonstrated an excellent pharmacokinetic profile and encouraging safety data in first-in-human studies earlier that year. Beyond kidney injury, MTX652 is being developed as a potential treatment for heart failure.

Advancing Novel Neurodegeneration Programs

In a significant development for its neurology portfolio, Mission recently initiated a landmark Phase I trial of MTX325 in March 2024. This USP30 inhibitor is being evaluated initially in healthy volunteers, with plans to assess its disease-modifying potential in Parkinson's disease patients later this year. The program holds additional promise for expansion into other neurodegenerative conditions, including amyotrophic lateral sclerosis.

Ongoing Strategic Partnership with AbbVie

Mission's collaboration with AbbVie, established in 2018, continues to progress in the Alzheimer's disease space. The partnership has shown notable success, with Mission achieving a significant milestone in 2021 that resulted in a $20 million payment. While specific details remain confidential, the collaboration involves two DUB targets under development.

Impact on Operations

The strategic realignment affects the company's preclinical research staff, though specific numbers have not been disclosed. Recent LinkedIn posts from employees have indicated operational changes, reflecting the company's shift toward clinical development focus. Despite these organizational changes, Mission maintains that its financial position remains strong, supporting continued development of its clinical programs.
