8-K: Cara Therapeutics to Merge with Tvardi Therapeutics, Focusing on STAT3-Targeted Therapies

Cara Therapeutics and Tvardi Therapeutics have agreed to merge, creating a combined entity focused on developing novel therapies targeting STAT3 for fibrosis-driven diseases.

Summary

• Cara Therapeutics and Tvardi Therapeutics have entered into a merger agreement, with Tvardi becoming a wholly-owned subsidiary of Cara.
• The combined company will focus on advancing Tvardi's programs, particularly its STAT3-targeting therapies for diseases like idiopathic pulmonary fibrosis (IPF) and hepatocellular carcinoma (HCC).
• The merger is expected to close in the first half of 2025, with the pro forma company ownership being 83% Tvardi and 17% Cara, assuming Cara has net cash of $22.875 million to $23.125 million at closing.
• The pro forma company will be well-capitalized, including $28.3 million from a recent Tvardi financing, and is expected to be funded into the second half of 2026.
• This funding will support multiple Phase 2 readouts in IPF and HCC expected in the second half of 2025 and prepare programs for Phase 3 development.
• Tvardi's management will operate the pro forma company, and the combined board will include six representatives from Tvardi and one from Cara.
• Tvardi's lead drug candidate, TTI-101, has shown promising results in preclinical and early clinical trials, demonstrating a dual mechanism of action by inhibiting STAT3's nuclear function without impacting its mitochondrial function.
• TTI-101 has shown potential in reversing fibrosis and improving lung function in IPF models, and early clinical data suggests encouraging trends in lung function.
• In HCC, TTI-101 has demonstrated durable partial responses in patients, with a 55% overall decrease in pY-STAT3 levels and a 79% decrease in stable disease patients.
• The company plans to submit an Investigational New Drug (IND) application for TTI-109 in the first half of 2025.

Industry Context

This merger reflects a trend in the biopharmaceutical industry where companies combine resources and expertise to accelerate the development of promising therapies. The focus on STAT3 as a target aligns with growing interest in novel approaches to treating fibrosis and cancer.

Comparison to Industry Standards

• The document compares TTI-101's performance in IPF to other recent studies, including PLN-74809, BMS-986278, and BI 1015550, noting that TTI-101's blinded data suggests a higher percentage of patients with stable or increased FVC.
• In HCC, TTI-101's early results are compared to trials of Tempest, MORPHEUS, and IMBrave150, showing a higher disease control rate and objective response rate in some cohorts.
• The document highlights that TTI-101 has shown a 55% overall decrease in pY-STAT3 levels and a 79% decrease in stable disease patients, which is a significant improvement compared to other therapies.
• The document notes that the current expected ORR in 2L HCC is <5%, while TTI-101 has shown a 33% ORR in monotherapy and 58% in combination therapy in early trials.

Stakeholder Impact

• Shareholders of both Cara and Tvardi will be impacted by the merger, with the potential for increased value if the combined company is successful.
• Employees of both companies will be impacted by the integration of the two organizations.
• Patients with IPF and HCC may benefit from the development of new therapies.
• Potential investors will be interested in the combined company's prospects.

Next Steps

• Complete the merger between Cara Therapeutics and Tvardi Therapeutics.
• Advance the development of Tvardi's programs, particularly TTI-101 and TTI-109.
