SOUTH SAN FRANCISCO, Calif., Nov. 08, 2022 (GLOBE NEWSWIRE) -- Sutro Biopharma, Inc. (Sutro or the Company) (NASDAQ: STRO), a clinical-stage oncology company pioneering site-specific and novel-format antibody drug conjugates (ADCs), today reported its financial results for the quarter ended September 30, 2022, its recent business highlights, and a preview of select anticipated milestones.
“We are pleased with the productivity and potential of our cell-free platform, as demonstrated most recently by Vaxcyte’s positive topline data readout for its 24-valent pneumococcal conjugate vaccine, VAX-24,” said Bill Newell, Sutro’s Chief Executive Officer. “We feel confident in the ability of our platform to generate additional value and capital, as exemplified by the iADC collaboration with Astellas. As we look towards the end of the year, we are on track to present the STRO-002 Phase 1 dose-expansion data and expect to be disclosing the study design on a registration-enabling Phase 2 study for patients with advanced ovarian cancer.”
Recent Business Highlights and Select Anticipated Milestones
STRO-002, FolRα-Targeting ADC: STRO-002 is being studied in the clinic, in both the U.S. and Europe, for patients with ovarian and endometrial cancers.
STRO-001, CD74-Targeting ADC: The Phase 1 study for patients with B-cell malignancies, including patients with non-Hodgkin’s lymphoma (NHL) and multiple myeloma (MM), continues in dose escalation.
Additional Pipeline Programs: A Sutro Research Forum highlighted STRO-003 and Sutro’s emerging research portfolio.
Collaboration Updates: Sutro continues to seek to maximize the value of its proprietary cell-free platform by working with partners on programs in multiple disease spaces and geographies and has generated from collaborators an aggregate of approximately $600 million in cash through September 30, 2022, which includes payments and equity investments.
Third Quarter 2022 Financial Highlights
Cash,CashEquivalentsandMarketableSecurities
As of September 30, 2022, Sutro had cash, cash equivalents and marketable securities of $287.3 million, as compared to $191.6 million as of June 30, 2022, providing a projected cash runway into the first half of 2024, based on current business plans and assumptions. The above balances do not include the value associated with Sutro’s holdings of Vaxcyte common stock.
UnrealizedGainfromIncreaseinValueofVaxcyteCommonStock
As of September 30, 2022, Sutro held approximately 1.5 million shares of Vaxcyte common stock, with a fair value of $36.9 million. The non-operating, unrealized gain of $3.5 million in the third quarter of 2022 was due to the increase since June 30, 2022 in the estimated fair value of Sutro’s holdings of Vaxcyte common stock. Vaxcyte common stock held by Sutro will be remeasured at fair value based on the closing price of Vaxcyte’s common stock on the last trading day of each reporting period, with any non-operating, unrealized gains and losses recorded in Sutro’s statements of operations. Sutro sold approximately 1 million shares of Vaxcyte common stock at fair market value during the period from October 1, 2022 through November 7, 2022.
Revenue
Revenue was $25.1 million for the quarter ended September 30, 2022, as compared to $8.5 million for the same period in 2021, related principally to recognition of the milestone payment from Merck and the Astellas, BMS, and EMD Serono collaborations in 2022 and the Merck, BMS, and EMD Serono collaborations in 2021. Future collaboration and license revenue from Astellas, Merck, BMS, EMD Serono, Tasly, and BioNova, and from any additional collaboration and license partners, will fluctuate as a result of the amount and timing of revenue recognition of upfront, milestones, and other agreement payments.
OperatingExpenses
Total operating expenses for the quarter ended September 30, 2022 were $46.4 million, as compared to $43.2 million for the same period in 2021. The third quarter of 2022 includes non-cash expenses for stock-based compensation of $6.8 million and depreciation and amortization of $1.4 million, as compared to $6.5 million and $1.1 million, respectively, in the comparable 2021 period. Total operating expenses for the quarter ended September 30, 2022 were comprised of research and development expenses of $31.7 million and general and administrative expenses of $14.6 million, which are expected to increase in 2022 as Sutro’s internal product candidates advance in clinical development and additional general and administrative expenses are incurred as a public company.
