Centessa Pharmaceuticals (CNTA) presents a compelling investment opportunity within the clinical-stage biopharmaceutical landscape. Our analysis supports a Buy rating with a 12-month price target of $22.00, representing a potential upside of 44% from the current share price of $15.25 (as of 29 August 2023).1 This thesis is anchored by the anticipated Phase 2a data readout for ORX750, Centessa’s lead orexin receptor agonist targeting narcolepsy and idiopathic hypersomnia, expected in H2 2024.2 Coupled with a robust cash position mitigating near-term dilution risk, and a diversified pipeline, Centessa is poised to capture significant value in the underserved sleep disorder market.
Industry Overview
The global market for narcolepsy and idiopathic hypersomnia treatments is estimated at $3 billion and projected to expand at an 8.5% compound annual growth rate (CAGR) through 2030.3 Existing therapies primarily address symptoms rather than underlying causes, leaving a significant unmet need for more effective treatments. Centessa aims to disrupt this landscape with its innovative orexin receptor agonist technology, which holds the potential to improve both daytime sleepiness and cognitive function in patients.
Company Analysis
Centessa operates as a clinical-stage biopharmaceutical company focused on developing novel treatments for neurological disorders. Their core programmes revolve around the orexin pathway, a critical regulator of wakefulness and arousal. ORX750, their lead candidate, represents a potential first-in-class oral OX2R agonist poised to enter Phase 2b trials. Beyond ORX750, Centessa’s preclinical pipeline, including ORX142 and ORX489, leverages the proprietary LockBody® platform for immuno-oncology applications, offering further diversification and long-term growth potential. Currently, Centessa generates no revenue, with operations funded by a substantial cash reserve.
Investment Thesis
Our investment thesis rests on three key pillars: the potential clinical success of ORX750, the company’s strong financial footing, and the broader market opportunity within the sleep disorder space. Positive Phase 2a data for ORX750 could validate its efficacy and safety profile, unlocking substantial upside potential given the significant unmet need. Centessa’s cash runway, estimated to extend into mid-2027, provides ample resources to advance its pipeline and minimises the risk of near-term dilutive financing. Finally, the growing prevalence of sleep disorders and the limitations of current treatments create a favourable market backdrop for innovative therapies like ORX750.
Valuation & Forecasts
We employed a discounted cash flow (DCF) model to assess Centessa’s intrinsic value. Our base case assumes a 50% probability of success for ORX750 in narcolepsy, with peak sales reaching $1.2 billion. We incorporated a discount rate of 12%, reflecting the inherent risks associated with clinical-stage biotech companies. Our model yields a base case valuation of $18.00 per share, with a bull case scenario reaching $25.00 if ORX750 demonstrates exceptional efficacy and captures significant market share.
| Metric | 2024E | 2025E | 2026E |
|---|---|---|---|

| FCF ($M) | -130 | -160 | -190 |
Risks
Key risks to our investment thesis include the possibility of negative or inconclusive clinical trial results for ORX750, unexpected regulatory hurdles, competitive pressures from existing and emerging therapies, and the inherent volatility of the biotech sector. While Centessa’s cash position mitigates immediate funding risks, future capital raises may be required to support late-stage clinical development and commercialisation, potentially diluting existing shareholders.
Recommendation
Despite these risks, we believe the potential rewards outweigh the challenges. Centessa’s innovative approach to addressing unmet needs in the sleep disorder market, coupled with its strong financial position and promising pipeline, warrants a Buy rating. We set a price target of $22.00, reflecting our base case valuation and the anticipated positive inflection point upon the release of Phase 2a data for ORX750. Investors should, however, be aware of the inherent risks associated with clinical-stage biotech investments and position their portfolio accordingly.
