Sutro’s novel iADC modality was generated with Sutro’s proprietary and integrated cell-free protein synthesis platform and site-specific conjugation platform. The molecule allows for a single therapy to target tumors with conjugated toll-like receptor (TLR) agonist in addition to a conjugated cytotoxic warhead. The iADC modality provides for dual mechanisms to attacking the tumor, through cytotoxic killing as well as potentially building a protective immune response. Using dual conjugations to deliver both components as systemic therapy potentially broadens the types of tumors that can be treated.
"This novel iADC modality is a further confirmation of the fruitful journey at Sutro, building upon a decade of research working with precisely conjugated ADCs," commented Trevor Hallam, Ph.D., President of Research and Chief Scientific Officer of Sutro. "Sutro’s novel iADC technology has therapeutic potential in difficult-to-treat cancers by both directly targeting cancer cells and activating the patient’s own immune system through the dual mechanism of action. With this technology, we can potentially develop an off-the-shelf therapy that aims to program a patients natural immune response to treat cancer and protect against future disease."
Dr. Hallam presented virtually at a session during the pre-conference seminar titled, "A New Molecular Class to target Tumor Immunity by both disrupting the tumor and enabling the immune system" on Tuesday, March 29, 2022.
Arturo Molina, M.D., M.S., FACP, Chief Medical Officer of Sutro, presented a session titled "Targeting FolRα in Gynecologic Cancers & other Solid Tumours with the Novel Antibody-Drug Conjugate, STRO-002," on Wednesday, March 30. The talk examined nonclinical and clinical data of STRO-002 in ovarian, endometrial, and other cancers, including the previously disclosed interim dose-expansion data of STRO-002-GM1.
