TD Cowen initiates Sionna Therapeutics stock with Buy rating

On Tuesday, TD Cowen began coverage on Sionna Therapeutics (NASDAQ:SION) shares, assigning them a Buy rating. The move comes as the firm takes a favorable view of Sionna’s potential in the cystic fibrosis (CF) treatment space, despite the stock’s recent 42% decline year-to-date. TD Cowen’s analysis is based on Sionna’s innovative approach to targeting a previously challenging aspect of the disease. According to InvestingPro data, analysts have set price targets ranging from $32 to $45 for the stock.

Sionna Therapeutics, with a market capitalization of $636 million, is focused on developing therapies that directly target the Nucleotide Binding Domain 1 (NBD1), a key component in the cystic fibrosis disease process. TD Cowen’s coverage note highlighted the significance of Sionna’s pipeline, emphasizing the promising in vitro and early clinical data. According to the research firm, Sionna’s drug candidates demonstrate good pharmacokinetics and pharmacodynamics (PK/PD) and could potentially improve or normalize the function of the CF Transmembrane Conductance Regulator (CFTR) when used in combination therapies.

The firm’s optimism is further bolstered by Sionna’s ongoing Phase 1 Single Ascending Dose/Multiple Ascending Dose (SAD/MAD) trials for their drug candidates SION ’719 and SION ’451. These trials are expected to yield data in the first half of 2025. Building on this momentum, Sionna Therapeutics plans to initiate a Phase 2a Proof of Concept (POC) trial in the second half of 2025, with results anticipated in 2026.

TD Cowen’s initiation of coverage on Sionna Therapeutics with a Buy rating reflects confidence in the company’s strategic approach to cystic fibrosis treatment. This coverage could potentially signal to investors the firm’s belief in Sionna’s capacity to make significant strides in the CF therapeutic market in the coming years.
