Protara Therapeutics Achieves Major FDA Milestones for TARA-002
On January 5, 2026, Protara Therapeutics, Inc. (Nasdaq: TARA), a pioneering clinical-stage biotechnology firm, announced significant advancements in the development of its investigational cell-based therapy, TARA-002. The U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy and Fast Track designations for TARA-002, which targets pediatric patients suffering from macrocystic and mixed cystic lymphatic malformations (LMs).
Implications of FDA Designations
The Breakthrough Therapy designation is designed to expedite the development of medications that show promise in treating serious conditions. TARA-002's selection signifies the FDA's recognition of the therapy's potential to substantially improve clinical outcomes for patients. The Fast Track designation further facilitates the review process for therapies that address serious conditions with significant unmet medical needs.
Additionally, TARA-002 has been included in the FDA's Chemistry, Manufacturing, and Controls (CMC) Development and Readiness Pilot (CDRP) Program, which aims to accelerate the manufacturing processes of products during clinical development stages. This initiative is pivotal in enabling quicker patient access to new therapies.
Expert Commentary
Jesse Shefferman, CEO of Protara Therapeutics, emphasized the importance of these designations: “Receiving these important FDA designations and invitation to participate in the CDRP program highlights the significant unmet need among pediatric patients with LMs and underscores our belief that TARA-002 could serve as a meaningful treatment option for this underserved patient population.” The company aims to meet with the FDA in the coming months to outline a path toward registration for TARA-002.
Understanding TARA-002 and Lymphatic Malformations
TARA-002 is an investigational therapy derived from a unique strain of streptococcus pyogenes, inactivated to preserve its immune-stimulating properties. It is based on a master cell bank shared with OK-432, a treatment that has been standard care for lymphatic malformations in Japan for over 30 years. TARA-002 has previously received the Rare Pediatric Disease designation, affirming its promise in this treatment space.
- Over 50% of lymphatic malformations are detected at birth.
- 90% are diagnosed before the age of three.
- Significant morbidities include airway obstruction, intralesional bleeding, and other serious functional disabilities.
