Summit Therapeutics stock reaffirmed at Market Outperform by Citizens

Investing.com - Citizens has reiterated its Market Outperform rating and $40.00 price target on Summit Therapeutics plc (NASDAQ:SMMT), a $15.6 billion market cap biotech company, following positive data for its cancer drug ivonescimab. The stock has declined 8.5% over the past week, with analyst targets ranging from $12 to $49.

The firm highlighted ivonescimab’s "broad dominance" in a head-to-head trial against tislelizumab (tisle), suggesting strong potential performance against pembrolizumab in the non-small cell lung cancer (NSCLC) market.

Citizens noted that ivonescimab demonstrated efficacy across all patient subgroups regardless of PD-L1 Tumor Proportion Score (TPS), indicating versatility in first-line NSCLC treatment settings.

The research firm emphasized that ivonescimab’s superiority over tislelizumab could potentially be extrapolated to other checkpoint inhibitor approved indications, expanding its market potential.
