Contineum Therapeutics Inc. (NASDAQ: CTNM) is facing fresh investor scrutiny after reporting that PIPE-307, one of its most advanced investigational drug candidates, failed to achieve key efficacy endpoints in a Phase 2 clinical trial targeting relapsing-remitting multiple sclerosis (RRMS). The topline data from the VISTA trial, announced on November 21, 2025, showed that while PIPE-307 was safe and well-tolerated across both dose arms, it did not produce a statistically significant improvement in the primary outcome measure, binocular 2.5 percent low contrast letter acuity.
This development marks a major setback for the neuroscience-focused drugmaker, which had positioned PIPE-307 as a differentiated oral therapy candidate within the remyelination space. The data miss now threatens to derail development momentum in multiple sclerosis and narrows near-term investor visibility into the company’s clinical pipeline outside of its IPF and chronic pain programs.
Contineum Therapeutics Chief Medical Officer and Head of Development, Dr. Timothy Watkins, acknowledged the trial’s failure to meet efficacy expectations, calling the outcome disappointing but affirming that the company remains committed to pursuing novel therapies for patients with inflammatory and fibrotic diseases. He also noted that further interrogation of the exploratory data is ongoing and that full results would be presented at a future medical conference and submitted to a peer-reviewed journal for publication.
The Phase 2 VISTA trial was designed as a randomized, double-blind, placebo-controlled, multi-center proof-of-concept study. In addition to low contrast visual acuity, the trial incorporated a range of imaging and clinical endpoints sensitive to remyelination in RRMS, making it a key inflection point for PIPE-307’s therapeutic relevance. With the topline data failing to meet its objectives, analysts expect Contineum Therapeutics to reassess PIPE-307’s development timeline, particularly in the RRMS indication.
How is the stock reacting and what are investors pricing in after the PIPE-307 trial outcome?
Shares of Contineum Therapeutics dropped sharply following the news, declining more than 11 percent during morning trading on November 21. By mid-morning, the stock was trading near $10.83, down from a previous close of $12.22. Intraday lows touched $10.40 before recovering slightly. The stock had traded as high as $12.94 the previous day, highlighting how quickly sentiment turned once investors digested the VISTA data.
Despite the one-day sell-off, Contineum Therapeutics remains up modestly over the trailing five-day period, indicating that investors may be differentiating between PIPE-307’s RRMS readout and the broader pipeline thesis. The 52-week trading range for the stock spans from $3.35 to $16.11, suggesting ample room for both pessimism and optimism as the company advances other assets.
Technical analysts will likely monitor the stock’s behavior around the 50-day moving average and key support levels in the $10–$10.40 range. Institutional investors are expected to shift focus toward the company’s lead fibrosis and chronic pain programs, which may offer nearer-term catalysts.
What does the failed trial mean for the PIPE-307 asset overall and its role in Contineum’s development pipeline?
While the failure in RRMS is a setback, PIPE-307 is not being abandoned altogether. Contineum Therapeutics has previously licensed the compound to Johnson & Johnson for development in major depressive disorder. Under the compound code JNJ-89495120, PIPE-307 is currently being evaluated in the Phase 2 Moonlight-1 trial. That study, which began enrolling in December 2024, is a randomized, double-blind, placebo-controlled, multicenter trial aimed at establishing the drug’s efficacy, safety, and tolerability in adult patients with major depressive disorder. Recruitment is ongoing, with a target enrollment of 124 patients.
Although the VISTA results now dampen expectations for PIPE-307 in multiple sclerosis, the molecule’s potential in central nervous system conditions remains an open question. Investors and analysts are expected to closely track the Moonlight-1 trial as a litmus test for whether PIPE-307 has a future in neuropsychiatric indications.
Contineum Therapeutics has not confirmed whether it will completely discontinue RRMS development or explore alternate formulations or biomarkers that could better predict response. Until full exploratory endpoint data is released, the outlook for PIPE-307 in RRMS remains highly uncertain.
What clinical and financial milestones are shaping sentiment around PIPE-791 and the rest of the pipeline?
The company’s attention is now expected to pivot decisively toward PIPE-791, an LPA1 receptor antagonist being developed for idiopathic pulmonary fibrosis and chronic pain. In September 2025, Contineum reported positive topline data from a PET imaging study that demonstrated high brain receptor occupancy in both healthy volunteers and patients with progressive multiple sclerosis, with a clear pharmacokinetic correlation between drug exposure and receptor engagement.
Contineum Therapeutics intends to initiate a global Phase 2 trial of PIPE-791 in idiopathic pulmonary fibrosis in the fourth quarter of 2025. The trial is expected to build on prior safety and PK data and will likely serve as the company’s next major value-creation milestone.
The company is also conducting a separate Phase 1b trial of PIPE-791 in patients with chronic osteoarthritis and lower back pain. That trial began dosing in March 2025 and is expected to deliver topline data in the first half of 2026. With the PIPE-791 program now representing the core of Contineum’s development focus, investor expectations are shifting toward this dual-path strategy in fibrotic and pain-related disorders.
To extend financial flexibility, the company has made the decision to defer development activities on its PIPE-791 program in progressive multiple sclerosis and its CTX-343 candidate. This has allowed Contineum to extend its projected cash runway to 2028.
What do the third-quarter financials reveal about Contineum’s capital strength and R&D priorities?
Contineum Therapeutics ended the third quarter of 2025 with $182.4 million in cash, cash equivalents, and marketable securities. The company also raised $19 million during the quarter via at-the-market offerings, selling approximately 3.2 million shares of Class A common stock at a weighted average price of $6.04 per share.
Research and development expenses rose to $11 million, marking a 13 percent increase from the same period in 2024. This increase was primarily attributed to the advancement of clinical programs including PIPE-307 and PIPE-791, along with higher employee-related costs. General and administrative expenses rose 21 percent year-over-year to $3.9 million, driven by increased stock-based compensation and staffing needs.
The net loss for the quarter came in at $12.8 million, compared to $10.3 million in the prior-year period. While the rising burn rate reflects a maturing clinical portfolio, the strengthened balance sheet provides Contineum with runway to pursue its key trials and operational priorities without immediate dilution concerns.
What should investors track next as Contineum regroups post-RRMS trial failure?
With PIPE-307’s Phase 2 failure in RRMS now confirmed, investors are likely to recalibrate their focus toward near-term catalysts in Contineum Therapeutics’ pipeline. Key events that could influence sentiment include:
The launch of the global Phase 2 trial for PIPE-791 in idiopathic pulmonary fibrosis by the end of 2025. The readout of topline data from the PIPE-791 chronic pain trial, expected in the first half of 2026. Interim updates or data disclosures from the Johnson & Johnson-sponsored Moonlight-1 trial of PIPE-307 in major depressive disorder. Full publication or presentation of the VISTA trial exploratory endpoint results to assess potential subpopulation insights.
Until these milestones materialize, analysts covering the stock suggest that buy-side attention will shift to the risk-reward balance of PIPE-791 and how successfully Contineum can pivot its development strategy. While PIPE-307’s trial failure has bruised sentiment, the company’s diversified NI&I pipeline and conservative capital allocation provide a runway for recovery.
