Business Overview
Trevi Therapeutics is a clinical-stage biopharmaceutical company focused on developing Haduvio, an oral nalbuphine extended-release therapy targeting chronic cough in IPF and refractory chronic cough (RCC) patients. The company generates revenue through capital raises and is advancing clinical programs primarily through its IPF and RCC segments, aiming to fill significant unmet medical needs where no approved therapies exist.
Performance Analysis
Trevi’s fourth quarter results reflect increased investment in clinical development, with research and development expenses rising to $9.3 million from $6.5 million year-over-year, driven by intensified activity in the Phase 2b CORAL and Phase 2a RIVER trials, alongside the Human Abuse Potential (HAP) study. General and administrative expenses also increased modestly to $2.9 million due to higher stock-based compensation and personnel costs. The net loss expanded to $11.4 million from $7.8 million, consistent with the company’s commitment to advancing its pipeline.
Importantly, Trevi ended 2024 with $107.6 million in cash and marketable securities, bolstered by a $50 million underwritten offering in December. This strong liquidity position supports ongoing trials and planned regulatory interactions, with a cash runway extending into the second half of 2026. The company’s financial discipline aligns with its clinical execution, enabling sustained investment in pivotal studies without immediate financing pressure.
- Clinical Expense Growth: Increased R&D spend reflects accelerated trial enrollment and expanded study sites across multiple geographies.
- Stable Operational Metrics: Patient discontinuation rates remained in single digits throughout the CORAL trial, supporting data integrity.
- Capital Positioning: December equity raise strategically timed post-positive data to fund near-term milestones and reduce dilution risk.
Overall, the financial results underscore Trevi’s transition from early-stage development toward late-stage clinical validation, with resource allocation focused on maximizing the value of Haduvio’s differentiated profile.
Executive Commentary
"Trevi had three positive and meaningful clinical data read-outs over the past few months validating the strategy of developing Haduvio as a potential best-in-class therapy for chronic cough conditions."
Jennifer Good, President and CEO
"Our cash runway guidance into the second half of 2026 remains unchanged and funds completing our ongoing Phase IIb CORAL trials for chronic cough in patients with IPF, and based on our current estimates, our next RCC trial."

Strategic Positioning
1. Dual Indication Focus on IPF and RCC
Trevi’s strategic emphasis on both IPF chronic cough and refractory chronic cough leverages Haduvio’s dual central and peripheral opioid receptor mechanism, which differentiates it from peripherally acting competitors. The recent Phase 2a RIVER trial data demonstrated statistically significant efficacy in RCC, while the ongoing Phase 2b CORAL trial targets IPF, the company’s lead indication. This dual-indication approach positions Trevi to capture multiple underserved markets with high unmet needs.
2. Robust Clinical Execution and Data Integrity
The company’s clinical programs have maintained consistent enrollment and low discontinuation rates, with the sample size re-estimation confirming original powering assumptions. This operational discipline reduces regulatory risk and supports the credibility of upcoming data readouts. The absence of protocol changes post-SSRE further ensures data comparability across enrollment phases.
3. Regulatory Engagement and NDA Planning
Trevi plans to pursue an end-of-Phase II meeting with the FDA by year-end 2025 to discuss pivotal trial design and safety database requirements. The company’s strategy to file an NDA initially for IPF chronic cough, followed by a supplemental NDA for RCC, reflects a methodical regulatory pathway. The Human Abuse Potential study’s positive results support the expectation that Haduvio will remain unscheduled, potentially facilitating market access.
4. Commercial Positioning Targeting Treatment Failures
In RCC, Trevi aims to position Haduvio as a second or third-line therapy for patients who have failed existing off-label treatments and potentially P2X3 antagonists, which currently address only severe cough subpopulations. This targeted approach may allow Trevi to maintain specialty pricing aligned with its IPF indication and address a substantial unmet patient segment.
5. Financial Stewardship Supporting Long-Term Development
The company’s $107.6 million liquidity, including a recent $50 million capital raise, provides runway into late 2026, covering ongoing trials and initial RCC study costs. This financial foundation enables Trevi to execute its clinical and regulatory plans without immediate capital constraints, a critical factor for clinical-stage biopharmaceutical companies navigating multiple late-stage studies.
Key Considerations
Trevi’s 2024 performance reflects a well-executed clinical development strategy with a clear focus on chronic cough indications and a financially prudent approach to funding. The following considerations are pivotal for investors assessing the company’s trajectory:
- Clinical Differentiation: Haduvio’s mixed kappa agonist and mu antagonist (KAMA) mechanism targets cough hypersensitivity centrally and peripherally, potentially offering broader efficacy than competitors focused solely on peripheral pathways.
- Trial Design and Placebo Effects: The company’s conservative assumptions around placebo response and consistent enrollment metrics reduce execution risk and support data robustness.
- Regulatory Milestones: Upcoming Phase 2b CORAL data and planned FDA meetings are critical inflection points that will influence pivotal trial design and eventual market approval timelines.
- Market Positioning in RCC: Targeting treatment failure patients post-P2X3 antagonist approval could carve a sustainable niche, but competitive dynamics and payer acceptance remain to be tested.
- Cash Burn Trajectory: Expected quarterly cash burn of $12 to $14 million in early 2025 aligns with clinical program expansion but will require monitoring as late-stage trials commence.
Risks
Trevi faces typical clinical-stage biopharmaceutical risks, including the possibility that upcoming trial data may not replicate prior positive outcomes or meet regulatory expectations. The reliance on a limited number of pivotal studies to support NDA filings adds concentration risk. Competitive pressures from other chronic cough therapies, including P2X3 antagonists, and uncertainties around market adoption and reimbursement also present material challenges. Additionally, while the HAP study supports an unscheduled status for Haduvio, final DEA scheduling decisions remain pending and could impact commercialization.
Forward Outlook
For Q1 2025, Trevi expects to continue investing in clinical development with cash burn net of interest income estimated between $12 million and $14 million per quarter. The company anticipates announcing topline data from the Phase 2b CORAL trial in IPF chronic cough patients in Q2 2025.
- Completion of CORAL trial enrollment and data readout expected in Q2 2025.
- Preparation for end-of-Phase II FDA meeting by end of 2025 to define pivotal program.
Management plans to initiate protocol development for the next RCC study, incorporating feedback from the FDA and leveraging insights from the recent RIVER trial data.
