Shuttle Pharma Secures $4.25 Million in Private Placement Deal
Biotech firm taps accredited investor to support acquisitions and marketing efforts.

Shuttle Pharmaceuticals (NASDAQ: SHPH) has locked in a $4.25 million private placement with an accredited investor, bolstering its war chest as the company continues to develop therapies that enhance the effectiveness of radiation therapy (RT) for cancer patients. The offering, priced at-the-market under Nasdaq rules, involves the sale of 1,180,877 shares of common stock, or pre-funded warrants, at $3.60 per share.
The transaction, announced on June 20, 2025, positions the development-stage biotech company to advance its strategic goals, which include potential acquisitions, expanded marketing initiatives, and broader corporate objectives. Shuttle Pharma confirmed that WestPark Capital will serve as the exclusive placement agent for the offering, which is expected to close on or around June 23, pending customary closing conditions.
Fueling Growth and Expanding Reach
With the additional capital, Shuttle Pharmaceuticals aims to ramp up efforts to strengthen its position in the oncology space. The company remains focused on improving outcomes for cancer patients undergoing radiation therapy by developing radiation sensitizers, compounds that enhance the ability of radiation to destroy cancer cells while minimizing damage to healthy tissue.
According to the company, the funds will support its broader mission to improve survival rates and quality of life for cancer patients. This infusion of capital could also signal future business development activity, particularly acquisitions that align with Shuttle’s growth strategy.
Regulatory Framework and Offering Mechanics
The securities included in the private placement have not been registered under the Securities Act of 1933 and will only be offered to accredited investors. As part of the deal, Shuttle agreed to a registration rights agreement, committing to file one or more registration statements with the Securities and Exchange Commission (SEC) to cover the resale of both the shares and any shares issued through the exercise of pre-funded warrants.
The company noted it will disclose further information regarding the transaction in a forthcoming Form 8-K filing with the SEC.
Positioned for Impact in Cancer Therapy
Shuttle Pharmaceuticals continues to push forward as a specialty biotech firm focused squarely on the intersection of radiation therapy and pharmaceutical innovation. By working to improve the therapeutic index of RT, the company hopes to boost cancer cure rates, extend survival, and reduce the collateral damage of treatment.
With this latest funding round, SHPH has taken a meaningful step toward executing that vision. Investors will now watch closely to see how the company deploys its new capital in a sector where innovation could mean the difference between remission and recurrence.
