Arvinas unveils preclinical findings for ARV-806
ARV-806 Overview: Arvinas presented preclinical data for ARV-806, a PROTAC KRAS G12D degrader, at the 2025 AACR-NCI-EORTC conference, highlighting its potential to target both ON and OFF forms of the KRAS G12D mutation, which is prevalent in various solid tumors.
Efficacy and Potency: The data showed that ARV-806 effectively degraded KRAS G12D with high potency in cancer cell lines and demonstrated significant tumor volume reductions in preclinical models, indicating its potential as a best-in-class therapy for KRAS G12D mutated cancers.
Clinical Development: Arvinas is currently conducting a Phase 1 clinical trial for ARV-806 in patients with advanced solid tumors harboring the KRAS G12D mutation, aiming to address the unmet medical needs in this area.
Pharmacodynamic Activity: ARV-806 exhibited sustained pharmacodynamic activity, maintaining target degradation for over a week, which supports the possibility of intermittent dosing in clinical settings.

Arvinas Initiates ARV-393 and Glofitamab Combination Trial for DLBCL Expected in 2026
- Clinical Trial Launch: Arvinas plans to initiate a combination clinical trial of ARV-393 and glofitamab in 2026, aiming to provide a chemotherapy-free treatment option for patients with diffuse large B-cell lymphoma, addressing a significant unmet medical need.
- Significant Efficacy: In a high-grade B-cell lymphoma model, the combination of ARV-393 and glofitamab achieved an 81% tumor growth inhibition rate, demonstrating substantial synergistic anti-tumor effects that could offer a more effective treatment option for patients.
- Mechanistic Research Support: RNA sequencing analysis revealed that ARV-393 upregulates CD20 expression and promotes interferon signaling pathways, indicating a strong mechanistic rationale for its combination with glofitamab, providing theoretical support for future clinical applications.
- Market Potential: As demand for chemotherapy-free treatment options increases, this research by Arvinas not only aims to improve patient quality of life but also positions the company to capture market share in the competitive biopharmaceutical landscape.

Arvinas Initiates ARV-393 and Glofitamab Combination Trial for DLBCL, Expected in 2026
- Trial Initiation: Arvinas plans to initiate a combination clinical trial of ARV-393 and glofitamab in 2026, aiming to provide a chemotherapy-free treatment option for patients with diffuse large B-cell lymphoma, addressing a significant unmet medical need.
- Preclinical Data: In a high-grade B-cell lymphoma model, the combination of ARV-393 and glofitamab achieved an 81% tumor growth inhibition rate, demonstrating significant synergistic anti-tumor effects and indicating the clinical potential of this combination.
- Dose Optimization: At a higher dose of 6 mg/kg for ARV-393, the combination therapy showed increased tumor regression rates, with complete regression observed in 10 out of 10 mice, highlighting the efficacy and safety of this treatment approach.
- Mechanistic Insights: RNA sequencing revealed that ARV-393 upregulates CD20 expression and enhances interferon signaling pathways, which may provide a mechanistic basis for its synergistic effects with glofitamab, further supporting its clinical rationale.
