  • The $100 million equity raise is expected to fund commercialization preparations for CAN-2409 in early-stage, localized prostate cancer.
  • Candel also plans to use part of the funds to support the ongoing phase 3 trial of CAN-2409 in non-small cell lung cancer.
  • RTW is set to receive a tiered single-digit percentage of U.S. net sales, subject to a cap.

Shares of Candel Therapeutics, Inc. (CADL) fell 14% in extended trading on Thursday, after the company outlined plans for a $100 million public stock offering, outweighing a $100 million royalty funding agreement announced the same day.

Candel Launches $100M Public Offering

Candel said it has launched an underwritten public offering of $100 million of its common stock. The underwriters have also been granted a 30-day option to purchase up to an additional $15 million in shares on the same terms.

According to the company, the proceeds will go toward preparing for the potential launch of Aglatimagene Besadenovec, also known as CAN-2409, in early-stage, localized prostate cancer. This includes medical affairs, launch readiness and other commercialization-related work. Candel also plans to use part of the funds to support the ongoing phase 3 trial of CAN-2409 in non-small cell lung cancer.

RTW Royalty Deal Adds $100M In Funding

Earlier in the day, Candel separately disclosed a $100 million royalty funding agreement with funds managed by RTW Investments. The deal will support a potential U.S. launch of CAN-2409 in intermediate to high-risk localized prostate cancer.

The royalty financing is tied to regulatory progress. It will become available upon approval of CAN-2409 by the U.S. Food and Drug Administration (FDA). Under the terms of the agreement, RTW would receive a tiered single-digit percentage of annual U.S. net sales of the therapy, subject to a cap.
