Company Overview
89bio is focused on developing innovative therapies for patients with severe metabolic disorders. The company's primary asset, pegozafermin, is an FGF21 analog that has shown promise in treating MASH, formerly known as non-alcoholic steatohepatitis (NASH), and SHTG. With multiple Phase 3 trials underway, 89bio is positioning itself as a potential leader in addressing unmet medical needs in these indications.
Clinical Developments
Pegozafermin is currently being evaluated in three Phase 3 trials, targeting different MASH populations and SHTG. These trials represent significant milestones for 89bio, as each indication offers a potential market opportunity exceeding $1 billion. The company's clinical program design has received positive feedback from the U.S. Food and Drug Administration (FDA), potentially paving the way for expedited confirmatory outcomes.
Analysts are particularly interested in the upcoming data from Akero Therapeutics' (NASDAQ:AKRO) 96-week Phase 2b SYMMETRY study in F4 MASH patients, expected in February 2025. This data is considered crucial for assessing the probability of success for 89bio's own Phase 3 trials, given the similarities between pegozafermin and Akero's EFX, both being FGF21 analogs.
The scarcity of clinical data in F4 MASH patients adds weight to the anticipated results, as they could provide valuable insights into the efficacy of FGF21 analogs in advanced liver disease. Previous data from Akero's 36-week readout in October 2023 missed statistical significance but showed trends in fibrosis improvement and NASH resolution, leaving room for optimism in the longer-term data.
Market Landscape
The MASH treatment landscape is evolving rapidly, with FGF21 analogs expected to maintain a significant role, particularly for F2-F3 MASH patients. However, the potential impact of GLP-1 therapies on the market remains a subject of debate among analysts. Current projections suggest that GLP-1 therapies may not pose direct competition for the F4 MASH population, potentially carving out a distinct niche for drugs like pegozafermin.
89bio's position in this competitive space is bolstered by pegozafermin's potential advantages, including less frequent dosing and lower gastrointestinal side effects compared to some competitors. These factors could contribute to improved patient compliance, a critical aspect of chronic disease management.
Financial Performance
According to InvestingPro data, 89bio trades at 2.5x book value, with analyst price targets ranging from $12 to $49, suggesting significant potential upside. The market's perception of 89bio's value remains a topic of discussion, with analysts noting a valuation gap between 89bio and its peer, Akero Therapeutics. Some view this disparity as unjustified, considering 89bio's additional Phase 3 trial for SHTG, which represents an extra market opportunity.

The company's stock performance is closely tied to clinical trial outcomes and competitor data. Analysts suggest that positive readouts from Akero could potentially drive 89bio's shares up by more than 50-60%, highlighting the interconnected nature of valuations in the biotech sector.
Bear Case
How might disappointing long-term data affect ETNB's prospects?
The success of 89bio's pegozafermin hinges significantly on the durability and improvement of clinical results over extended periods. If longer-term data fail to demonstrate sustained efficacy or show deterioration compared to the 36-week dataset, it could severely impact investor confidence. Analysts caution that such a scenario might lead to a decline in ETNB shares by more than 40-50%.
The absence of compelling long-term data could also weaken 89bio's position in the competitive MASH treatment landscape, potentially allowing rival therapies to gain market share. This could result in reduced market potential for pegozafermin and diminish the company's ability to secure favorable partnerships or financing terms for future development and commercialization efforts.
What challenges does ETNB face in the competitive MASH treatment landscape?
89bio operates in an increasingly crowded field of MASH treatments, with various therapeutic approaches vying for market dominance. The emergence of GLP-1 therapies and other drugs targeting obesity and type 2 diabetes presents a complex competitive environment. While current analysis suggests that GLP-1s may not directly compete in the F4 MASH population, the overall impact on treatment paradigms and patient selection remains uncertain.
The company must also contend with the challenge of differentiating pegozafermin in a market where multiple FGF21 analogs are under development. As competitors like Akero Therapeutics advance their clinical programs, 89bio needs to clearly demonstrate pegozafermin's unique benefits to secure its market position. The lack of immediate clarity on MASH launch trajectories adds another layer of uncertainty, potentially affecting investor sentiment and the company's ability to plan for commercialization effectively.
Bull Case
How could positive AKRO data benefit ETNB?
Positive data from Akero Therapeutics' 96-week Phase 2b SYMMETRY study could have significant implications for 89bio. Given the similarities between pegozafermin and Akero's EFX, favorable results would likely be interpreted as a validation of the FGF21 analog approach in treating MASH. This could lead to increased confidence in 89bio's clinical program and potentially drive substantial appreciation in ETNB shares, with some analysts projecting gains of more than 50-60%.
Furthermore, positive AKRO data could attract more attention and investment to the MASH treatment space, potentially benefiting 89bio through increased partnering opportunities or improved financing conditions. It might also accelerate regulatory discussions and pave the way for a more streamlined approval process, as regulatory agencies become more familiar with the efficacy and safety profiles of FGF21 analogs in MASH treatment.
What advantages does pegozafermin offer over competitors?
Pegozafermin possesses several characteristics that could provide it with a competitive edge in the MASH and SHTG markets. The drug's less frequent dosing schedule compared to some alternatives could significantly improve patient adherence, a crucial factor in managing chronic conditions like MASH. Additionally, the reported lower incidence of gastrointestinal side effects may contribute to better tolerability and long-term compliance.
89bio's strategic decision to pursue both MASH and SHTG indications for pegozafermin positions the drug as a potential "pipeline-in-a-product." This dual-indication approach not only diversifies the company's market opportunities but also provides multiple paths to commercial success. The inclusion of an SHTG trial, which some competitors lack, could give 89bio access to an additional billion-dollar market, potentially justifying a higher valuation relative to peers focused solely on MASH.
