Silverback Therapeutics to Present SBT6290 Preclinical Data at the AACR 2021 Annual Conference
Silverback Therapeutics (Nasdaq: SBTX) will present preclinical data on SBT6290 at the AACR 2021 Conference, showcasing its potential to activate myeloid cells in tumors. SBT6290 targets Nectin4, overexpressed in several solid tumors, aiming to enhance immunotherapy efficacy. The data supports its anti-tumor activity and demonstrates the versatility of Silverback's ImmunoTAC platform, with plans for IND submission in Q4 2021. This candidate, along with the lead program SBT6050, focuses on overcoming immunotherapy resistance in difficult-to-treat cancers.
- SBT6290 shows promising preclinical data, indicating anti-tumor activity.
- Targets Nectin4, prevalent in multiple solid tumors, enhancing potential market appeal.
- Plans to submit an IND for SBT6290 in Q4 2021, indicating progress in development.
- Dependence on future clinical trials for validation of SBT6290's efficacy and safety.
- Potential delays in IND submission could impact investor confidence.
Silverback Therapeutics, Inc. (Nasdaq: SBTX) (“Silverback”), a clinical-stage biopharmaceutical company leveraging its proprietary ImmunoTAC technology platform to develop systemically delivered, tissue-targeted therapeutics for the treatment of cancer, chronic viral infections and other serious diseases, will present preclinical data on its second product candidate, SBT6290, at the American Association of Cancer Research (AACR) 2021 Annual Conference, taking place virtually April 10-15. The data highlight the ability of SBT6290, a systemically administered Nectin4-directed TLR8 ImmunoTAC product candidate, to selectively activate myeloid cells in the tumor microenvironment, a promising approach to overcome resistance mechanisms associated with most current immunotherapies.
“SBT6290 showcases the versatility of our ImmunoTAC platform and along with our lead program SBT6050, exemplifies our goal to target difficult-to-treat solid tumors subset by subset. We are building on learnings from SBT6050, leveraging the same TLR8 linker-payload, which is highly transferrable across different targeting antibodies,” said Valerie Odegard, Ph.D., president & chief scientific officer of Silverback Therapeutics. “These preclinical data show that SBT6290 activates human myeloid cells in a Nectin4-dependent manner and that a SBT6290 mouse surrogate confers single agent anti-tumor activity in preclinical studies. We will continue to evaluate SBT6290 in GLP toxicology studies and anticipate submitting an IND for this program in the fourth quarter of 2021.”
SBT6290 comprises a selective TLR8 agonist conjugated to a Nectin4-specific monoclonal antibody. Nectin4 is a cell surface adhesion molecule that is overexpressed in multiple solid tumor types including urothelial, triple negative breast, squamous cell head and neck, and non-small cell lung cancers, with limited expression in normal tissues.
The abstract is now available on the AACR Annual Meeting website. Details of the poster presentation are as follows:
Title: SBT6290, a Systemically Administered Nectin4-Directed TLR8 ImmunoTAC® Product Candidate, is Designed for Tumor-localized Activation of Myeloid Cells
Abstract Number: 1858
Session Category: Immunology
Session Title: Therapeutic Antibodies, Including Engineered Antibodies
Virtual Poster Session Date and Time: The poster will be made available on the AACR website and Silverback website on April 10, 2021 at 8:30 a.m. ET
