RayzeBio Reports Third Quarter 2023 Financial Results and Provides Corporate Update

SAN DIEGO, Nov. 13, 2023 (GLOBE NEWSWIRE) -- RayzeBio, Inc. (Nasdaq: RYZB), a targeted radiopharmaceutical company developing an innovative pipeline against validated solid tumor targets, today reported financial results for the third quarter ended September 30, 2023 and provided an update on key corporate initiatives.

“We have made significant progress in 2023 and achieved several clinical, discovery and corporate milestones as we continue to lead innovation in developing targeted radiopharmaceuticals for the benefit of patients with cancer,” said Ken Song, M.D., President and CEO of RayzeBio. “Our lead asset, RYZ101, is the first Actinium-225 based treatment in a Phase 3 clinical trial. We are on track to file an IND in the first half of 2024 for our next clinical drug candidate, which is focused on treating patients with liver cancer. Additionally, our oversubscribed IPO in September 2023 provides us with a strong balance sheet to fully invest in our initiatives.”

Recent Highlights and Upcoming Milestones

  • Enrollment ongoing for the Phase 3 portion of the ACTION-1 clinical trial as well as follow-up of patients from the Phase 1b: Enrollment is ongoing in the registrational global Phase 3 portion of the ACTION-1 clinical trial of RYZ101 for patients with SSTR2 expressing GEP-NETs who have experienced progression of their cancer following treatment with Lu177 somatostatin analog therapy. RayzeBio expects to present the Phase 3 interim analysis in late 2025 / early 2026. As part of the IPO and subsequently at ESMO in October 2023, RayzeBio reported the interim results of the Phase 1b portion of the ACTION-1 clinical trial, where RayzeBio enrolled a total of 17 patients. As of the last data cut off on June 30, 2023, treatment has been well tolerated with no treatment-related serious adverse events or dose discontinuations due to any adverse event. Additionally, five patients have had a confirmed partial response, or PR, which is based on two consecutive evaluations showing PR, representing a confirmed objective response rate, or ORR, of 29%. RayzeBio is continuing to monitor the patients and expects to present updated Phase 1b data at a medical conference during the first half of 2024.
  • RYZ801 and RYZ811 IND filing for HCC expected in 1H 2024: RYZ801 is a novel proprietary peptide which targets GPC3 for delivery of Ac225 for the treatment of HCC. Using Gallium 68, or Ga68, an imaging radioisotope, RayzeBio has already shown uptake of its novel proprietary peptide binder in patients with HCC via early human imaging studies conducted outside of the United States. RYZ801 is currently in IND enabling studies. Additionally, RayzeBio is developing RYZ811, which is a paired diagnostic imaging agent with the same peptide binder and chelator as RYZ801 but with Ga68 as the radioisotope. The Company plans to file an IND for each of RYZ801 and RYZ811 in the first half of 2024 followed by a Phase 1 clinical trial in HCC patients.
  • Buildout of our state of the art manufacturing facility on track to be completed by the end of 2023: RayzeBio expects its in-house manufacturing facility in Indianapolis to be completed by the end of 2023 with GMP drug production starting in the first half of 2024. This facility will be an important milestone in creating vertical integration, which is essential to be a successful targeted radiopharmaceutical company.
  • Completed $357 million upsized Initial Public Offering: In September, the Company completed its upsized IPO of 19,869,240 shares of common stock, at a price to the public of $18.00 per share. RayzeBio sold 18,706,240 shares of common stock and a selling stockholder sold 1,163,000 shares of common stock. The aggregate gross proceeds to RayzeBio from the offering, before deducting underwriting discounts and commissions and other offering expenses payable by RayzeBio, were approximately $336.7 million.
  • Strengthened team with key Board of Director Appointments: RayzeBio added seasoned biotech executive Christy Oliger to its board of directors in August 2023 to provide commercial expertise. Additionally, in November 2023, RayzeBio added Tim Van Hauwermeiren, co-founder and CEO of argenx to its board of directors, further strengthening the board.

Third Quarter Financial Results

  • Cash Position: As of September 30, 2023, RayzeBio had cash, cash equivalents and short-term investments of $540.2 million. RayzeBio projects its cash position is sufficient to fund operations through various milestones across its clinical programs.
  • Research and Development (R&D) Expenses: R&D expenses for the third quarter of 2023 were $18.2 million, compared to $18.8 million for the third quarter of 2022. R&D expenses decreased primarily due to reduction in expenses related to license rights, offset by increases related to the clinical advancement of RYZ101 in GEP-NETs, pre-clinical efforts for RYZ801 and personnel costs, including share-based compensation expense associated with the growth of the Company’s R&D team.
  • General and Administrative (G&A) Expenses: G&A expenses for the third quarter of 2023 were $3.5 million, compared to $2.1 million for the third quarter of 2022. The increase of $1.4 million was primarily attributable to the increase in personnel costs associated with increased headcount and legal and other professional services conducted to support the growth of the business.
  • Net Loss: Net loss for the third quarter of 2023 was $18.2 million, compared to the net loss for the third quarter of 2022 which was $20.4 million.
