$16.0 million in upfront gross proceeds with the potential to receive up to an additional $18.0 million in potential warrant exercise proceeds for an aggregate of up to $34.0 million in total gross proceeds

DOYLESTOWN, Pa., March 11, 2024 (GLOBE NEWSWIRE) -- Aprea Therapeutics, Inc. (Nasdaq: APRE) (“Aprea”, or the “Company”), a clinical-stage biopharmaceutical company focused on precision oncology through synthetic lethality, today announced that it has entered into a securities purchase agreement with new and existing healthcare focused institutional investors and certain Company insiders to raise up to $34.0 million in gross proceeds, including initial upfront funding of $16.0 million and up to an additional $18.0 million upon cash exercise of accompanying warrants at the election of the investors.

The financing is being led by Sphera Healthcare and includes participation from new and existing healthcare-focused investors, including Nantahala Capital, DAFNA Capital Management, Exome Asset Management and Stonepine Capital Management, among others, as well as certain Company insiders.

“This meaningful financing led by high quality healthcare institutions will support Aprea in our goal to be a leader in the field of Synthetic Lethality (SL) and DNA Damage and Response (DDR),” said Dr. Oren Gilad, President and CEO of Aprea. “It will provide the capital to fund our Phase 1 ACESOT-1051 clinical trial evaluating a highly potent, oral WEE1 inhibitor for Cyclin E over-expressing cancers including breast and ovarian cancers as well as continuation of patient enrollment in the dose expansion portion of the Phase 1/2a clinical trial (AR-276-01) evaluating ATR inhibitor, ATRN-119, in patients with advanced solid tumors having mutations in defined DDR-related genes.”

Maxim Group LLC is acting as the sole placement agent for the private placement.

Pursuant to terms of the securities purchase agreement, Aprea will issue an aggregate of 2,194,788 shares of its common stock (or pre-funded warrants in lieu thereof) and accompanying warrants to purchase up to an aggregate of 2,194,788 shares of its common stock at a combined purchase price of $7.29 per share and accompanying warrants, in accordance with the "Minimum Price" requirement as defined in the Nasdaq rules. The accompanying warrants will consist of two tranches:

• Tranche A warrants to purchase up to 1,097,394 shares of common stock at an exercise price of $7.29 per share for an aggregate of up to $8.0 million and will expire at the earlier of (i) 30 days following the announcement of the recommended Phase 2 dose for the Company’s ATR inhibitor program for ATRN-119 and the daily VWAP of the Company’s common stock equaling or exceeding $14.58 per share for 30 consecutive trading days following the announcement and (ii) three years from the date of issuance.
• Tranche B warrants to purchase up to 1,097,394 shares of common stock at an exercise price of $9.1125 per share for an aggregate of up to $10.0 million and will expire at the earlier of (i) 30 days following the announcement of the recommended Phase 2 dose for the Company’s WEE1 inhibitor program for APR-1051 and the daily VWAP of the Company’s common stock equaling or exceeding $18.225 per share for 30 consecutive trading days following the announcement and (ii) five years from the date of issuance.

In lieu of shares of common stock, certain investors are purchasing pre-funded warrants at a combined purchase price of $7.289 per pre-funded warrant and accompanying warrants, which equals the purchase price per share of common stock and accompanying warrant, less the $0.001 per share exercise price of each pre-funded warrant. The private placement is expected to close on or about March 13, 2024 subject to satisfaction of customary closing conditions.

Aprea intends to use the upfront net proceeds from the private placement for general corporate purposes and to fund clinical development of APR-1051, the Company’s WEE1 inhibitor product candidate which recently received IND clearance. The aggregate net proceeds (assuming the cash exercise of all accompanying warrants) are expected to be sufficient to fund the Company into 2026.
