Tourmaline Bio, Inc. (TRML)·Q4 2024 Earnings Summary
Executive Summary
- TRML delivered a clinical‑execution quarter: TRANQUILITY Phase 2 was over‑enrolled to 143 participants and timing was narrowed to topline data in Q2 2025, keeping ASCVD Phase 3 readiness on track .
- Cash, cash equivalents and investments ended at $294.9M, extending runway into the second half of 2027; OpEx rose with increased R&D tied to TRANQUILITY and spiriTED, driving Q4 net loss of $22.2M and EPS of $(0.86) .
- TED strategy was recalibrated: prior plan to initiate Phase 3 in H2 2024 shifted to “dependent upon Phase 2b spiriTED results,” indicating a more data‑driven sequence and reduced near‑term spend on TED Phase 3 .
- Street consensus (S&P Global) was unavailable via tool limits, so beats/misses vs estimates cannot be assessed; investor focus should center on Q2 2025 TRANQUILITY data and cash runway catalyst [GetEstimates error]*.
What Went Well and What Went Wrong
What Went Well
- TRANQUILITY exceeded the enrollment target (143 vs. 120 planned) and timeline was firmed to Q2 2025; management framed 2025 as “a potentially transformative year of data” .
- Strengthened cardiovascular credibility with a world‑class CV SAB (Ridker added in Jan., Simon added in Mar.), bolstering Phase 3 readiness for ASCVD and broader inflammation thesis .
- Management tone was confident about balance sheet and program momentum: “Complemented by our strong balance sheet…making further progress towards realizing the enormous standard‑of‑care changing potential of pacibekitug” .
What Went Wrong
- Q4 R&D expense increased to $20.5M (vs. $8.0M LY), reflecting higher trial, manufacturing, and medical affairs costs; net loss widened to $22.2M, highlighting cash burn as development scales .
- Cash declined sequentially to $294.9M (Q4) from $314.4M (Q3) and $334.4M (Q2), consistent with rising OpEx and trial activity .
- TED Phase 3 initiation was deferred from “on track in H2 2024” to “dependent on Phase 2b spiriTED results,” removing a near‑term TED P3 catalyst and concentrating value on cardiovascular readouts .
Financial Results
Segment reporting: Not applicable; TRML is a clinical‑stage biotech without commercial segments in the quarter .
Key Balance Sheet & Liquidity KPIs:
Drivers and notes:
- Q4 OpEx increase was driven by headcount, trial costs for TRANQUILITY and spiriTED, drug manufacturing, and medical affairs .
- Q4 G&A decreased y/y due to lower stock‑based comp; full‑year G&A increased on headcount, professional fees, and public company insurance costs .

Key Takeaways for Investors

- Liquidity is sufficient through multiple data events: runway into H2 2027 supports execution without immediate financing risk .
- Strategy tightened: TED Phase 3 shifted to post‑P2b data, reducing near‑term cash burn in TED and aligning spend with readouts .
- External validation building: CV SAB enhancements (Ridker, Simon) add credibility to the IL‑6 inflammation thesis across ASCVD and broader CVD .
- Balance sheet trends reflect focused development: sequential cash drawdown consistent with accelerated trial activity; monitor quarterly OpEx vs. clinical milestones .
- Pipeline optionality: AAA PoC planning after TRANQUILITY presents a second cardiovascular shot on goal .
- Trading lens: Position sizing should reflect binary‑type catalyst risk around Q2 2025 data—consider hedging strategies and scenario analysis around hs‑CRP reduction magnitude and safety profile communicated at topline .
