Sonnet BioTherapeutics (NASDAQ: SONN), a clinical-stage biotech company specializing in oncology-focused immunotherapies, has priced a $5.0 million underwritten public offering. The offering includes 1,111,111 shares of common stock, each sold with one common warrant for the purchase of an additional two shares, at a combined price of $4.50 per share. This offering is set to close on or around November 7, 2024, and is expected to generate gross proceeds of approximately $5.0 million before underwriting discounts and commissions.
The proceeds from this offering are intended to fund Sonnet’s ongoing research and development, clinical trials, working capital, and liability repayments, advancing the company’s mission to develop novel biologic therapies for cancer treatment. While the offering is an exciting opportunity for the company to secure necessary funding, it also brings with it potential risks, including the possibility of shareholder dilution through the issuance of new shares and warrants.
Notably, Sonnet’s share price has seen increased volatility today, with trading volume significantly surging. This rise in trading activity follows the announcement of the offering and its anticipated closure. As is often the case with at-the-market offerings under Nasdaq rules, the pricing of the shares could pressure the stock value in the short term. However, investors may also be reacting positively to the financial backing that will enable Sonnet to accelerate the clinical development of its promising drug pipeline.
Sonnet is known for its proprietary FHAB (Fully Human Albumin Binding) platform, which enables the development of biologic drugs designed to target tumor and lymphatic tissues more efficiently. This technology utilizes a human single-chain antibody fragment (scFv) to hitch a ride on human serum albumin, guiding the drug directly to the target tissue for improved therapeutic effectiveness. The FHAB platform is adaptable, enabling the creation of a wide range of therapeutic candidates, including cytokines, peptides, antibodies, and vaccines.
One of Sonnet’s leading therapeutic candidates is SON-1411, a novel bifunctional fusion protein designed to enhance the efficacy of the immune response against cancer. SON-1411 combines IL-18BPR (a receptor that binds IL-18) with IL-12 and is linked to the FHAB platform. This innovative approach is aimed at overcoming limitations observed in previous IL-18-based therapies, which suffered from poor efficacy due to the presence of IL-18 binding protein (IL-18BP) in the tumor microenvironment. By modifying the IL-18 domain, SON-1411 seeks to bypass this issue and enhance the therapeutic potential of IL-18 in cancer treatment.
In addition to SON-1411, Sonnet is also advancing SON-1010, an IL-12-FHAB fusion protein, through clinical trials for solid tumors and ovarian cancer. The company is evaluating SON-1010 in collaboration with Roche, in combination with the immune checkpoint inhibitor atezolizumab, for the treatment of platinum-resistant ovarian cancer. Moreover, Sonnet is working on SON-1210, a combination of IL-12-FHAB and IL-15, for the treatment of solid tumors like pancreatic cancer.
Despite the potential dilution concerns stemming from the offering, the announcement underscores the company’s strategic commitment to advancing its promising drug candidates. As Sonnet BioTherapeutics progresses through clinical trials and secures additional funding, the surge in trading volume today suggests strong market interest in the company’s future prospects. The funding from the offering will be crucial in supporting Sonnet’s clinical trials and advancing the company’s vision of delivering targeted, effective treatments for cancer patients.
