Management Comments

• Following a highly productive 2024 marked by positive data in our NMIBC program and with the funds from a successful financing, we are well positioned to accelerate our development programs and deliver on our mission to provide novel therapies to patients impacted by cancer and rare diseases, said Jesse Shefferman, Chief Executive Officer of Protara Therapeutics.
• On the heels of our recently reported positive interim data from six-month evaluable patients, we continue to believe that TARA-002 could represent a meaningful and differentiated addition to the NMIBC treatment paradigm with an attractive product profile for both physicians and patients.

Industry Context

Protara is developing TARA-002 for NMIBC, a market with significant unmet need, as current therapies for BCG-unresponsive NMIBC were approved based on single-arm trials, and radical cystectomy is often the standard of care after BCG failure.

Comparison to Industry Standards

• The 72% complete response rate at six months in the ADVANCED-2 trial compares favorably to other therapies in development for BCG-unresponsive NMIBC.
• TARA-002's administration is among the easiest of approved and experimental NMIBC treatments, potentially reducing the burden on physicians and patients compared to therapies like Adstiladrin and N-803/BCG-TICE.

Stakeholder Impact

• Shareholders: The positive data and strengthened financial position are likely to be viewed favorably by shareholders.
• Patients: The development of TARA-002 and IV Choline Chloride offers potential new treatment options for patients with NMIBC, LMs, and choline deficiency.
• Employees: The company's progress and financial stability provide job security and opportunities for growth.

Next Steps

• Report data on 12-month evaluable patients in the ADVANCED-2 trial in mid-2025.
• Report results from a futility analysis of approximately 25 six-month evaluable BCG-Unresponsive patients by the end of 2025.
• Commence the THRIVE-3 registrational trial of IV Choline Chloride in the first half of 2025.
• Report initial results from additional cohorts in the Phase 2 STARBORN-1 trial of TARA-002 in pediatric patients with LMs by the end of the first half of 2025.
• Provide an update on the design of its planned BCG-Nave registrational trial by the end of the first half of 2025 following regulatory alignment.
• Continue to explore the administration of systemic priming dosing prior to initiation of intravesical administration, as well as combination therapy with TARA-002 in NMIBC patients with CIS.
