SOUTH SAN FRANCISCO, Calif., Nov. 12, 2026 (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 third quarter ended September 30, 2026 and recent business highlights.<\/p>\n

\u201cOver the past year, we have delivered on our commitment to advance our next-generation ADCs with two programs, STRO-004 and STRO-006, entering the clinic in less than a year, and our dual-payload ADC, STRO-227, expected to follow in early 2027,\u201d said Jane Chung, Chief Executive Officer of Sutro. \u201cEarly data from STRO-004 give us confidence in its potential to deliver meaningful clinical benefit with our proprietary ADC platform. In addition, our collaboration partner Astellas has initiated patient dosing with a second dual-payload immunostimulatory ADC, further highlighting our strong execution and ability to deliver differentiated, novel dual-payload ADCs. Together these advances reflect our proficiency in translating platform innovation into a growing pipeline of therapies designed to improve patient outcomes and create long-term value.\u201d<\/p>\n

\n
\n Sutro Pipeline<\/u>
\n <\/strong>\n <\/p>\n

\n STRO-004:<\/strong> Sutro\u2019s potential best-in-class Tissue Factor (TF)-targeting DAR8 exatecan ADC is being evaluated in the ongoing Phase 1 STRIV<\/em>E-01 study in patients with advanced solid tumors. As previously reported in August 2026, initial dose escalation in 49 heavily pretreated patients demonstrated encouraging early clinical activity, including confirmed and ongoing unconfirmed partial responses across three tumor types in RECIST-evaluable patients, alongside favorable tolerability and a differentiated pharmacokinetic profile. Dose optimization continues in backfill cohorts of selected indications. The Company plans to provide its next STRIV<\/em>E-01 study update and initiate expansion cohorts in select indications in the first half of 2027.<\/p>\n

\n STRO-006:<\/strong> Sutro\u2019s next-generation, highly selective integrin \u03b26 (ITGB6)-targeting ADC with a DAR8 exatecan payload, is designed for the treatment of multiple solid tumors. In October 2026, the Company announced the first patient dosed in a Phase 1, open-label, multicenter study evaluating the safety, tolerability, pharmacokinetics and preliminary antitumor activity of STRO-006 as a monotherapy in adults with advanced or metastatic solid tumors. The dose-escalation portion will enroll patients with ITGB6-expressing tumor types, including head and neck cancer, non-small cell lung cancer, esophageal\/gastric cancer, colorectal cancer, endometrial cancer, urothelial cancer and breast cancer, with dosing beginning at 1.5 mg\/kg. The Company anticipates an initial Phase 1 data update in the second half of 2027.<\/p>\n

\n STRO-227:<\/strong> Sutro\u2019s DAR10 dual-payload ADC targeting PTK7, consists of MMAE (DAR2) and exatecan (DAR8) payloads to enable complementary mechanisms of action within a single molecule. The program is advancing toward initiation of a Phase 1 clinical trial in early 2027 and is a key component of Sutro\u2019s strategy to expand its portfolio of ADCs designed for the potential to widen the therapeutic index and overcome resistance.<\/p>\n

\n
\n Next-Generation ADC Collaborations<\/u>
\n <\/strong>\n <\/p>\n

\n Astellas:<\/strong> Two programs are advancing in the clinic under Sutro\u2019s collaboration with Astellas focused on dual-payload immunostimulatory ADCs (iADCs). The first program, which targets TROP2, continues to actively dose patients.<\/p>\n

The second program, targeting B7-H3, began dosing patients, resulting in a $10 million milestone payment received by Sutro in October 2026.<\/p>\n

\n
\n Recent Scientific Presentations<\/u>
\n <\/strong>\n <\/p>\n

At the 17th Annual World ADC Conference held October 12\u201315, 2026, Sutro presented initial STRO-004 clinical safety and pharmacokinetic findings in a plenary session, along with new preclinical updates on STRO-006, STRO-227 and novel payload mechanisms, demonstrating the potential of the Company\u2019s platform to deliver next-generation ADCs with a wider therapeutic index and the potential to overcome resistance to single-payload ADCs. The presentations are available in the Scientific Publications section of Sutro Biopharma\u2019s website at www.sutrobio.com.<\/p>\n
