Breaking Down Silverback Therapeutics, Inc. (SBTX) Financial Health: Key Insights for Investors

Born in 2016 and headquartered in Seattle, Silverback Therapeutics set out to improve patients' lives by developing tissue-targeted therapeutics using its proprietary ImmunoTAC™ platform, with a mission rooted in scientific excellence, patient-centricity, and ethical governance; the company pursued potent, locally acting therapies to precisely modulate immune and oncologic pathways while minimizing systemic toxicities, but in March 2022 restructured to discontinue lead oncology programs and concentrate on chronic hepatitis B virus (cHBV) and ImmunoTAC discovery programs, ultimately completing a reverse merger in November 2022 with ARS Pharmaceuticals (ceasing independent operations and retiring its NASDAQ ticker SBTX), developments that reshaped its vision to focus resources on high unmet medical needs and underscore the core values that guided its strategic pivots-read on to explore how mission, vision, and values intersected with these pivotal corporate milestones

Silverback Therapeutics, Inc. (SBTX) - Intro

• Advance differentiated, tissue-selective therapeutics that provide meaningful clinical benefit with improved safety margins compared with systemic agents.
• Translate platform innovation into scalable programs in infectious disease (cHBV) and targeted immuno-oncology approaches where local activity drives therapeutic index.
• Foster partnerships and disciplined capital stewardship to extend runway for discovery and early clinical milestones.

• Patient First - development decisions driven by patient benefit and tolerability.
• Scientific Integrity - rigorous, evidence-based research and transparent reporting.
• Collaboration - multidisciplinary teamwork and external partnerships to accelerate translation.
• Accountability - ethical governance, regulatory compliance, and responsible resource allocation.

• Discovery-through-clinic pathway emphasizing tissue selectivity and therapeutic index improvement.
• Prioritization of cHBV programs to address significant unmet global burden and durable virologic suppression goals.
• Continued preclinical ImmunoTAC expansion to identify additional tissue-targeted indications with high unmet need.

• Pipeline focus and platform potential are central to SBTX's value proposition following the March 2022 pivot.
• Operational discipline and targeted resource deployment guide program prioritization and external collaborations.

Silverback Therapeutics, Inc. (SBTX) - Mission Statement

• Develop locally acting, tissue-targeted medicines that reduce systemic exposure and adverse events.
• Leverage the proprietary ImmunoTAC™ platform to direct immune effector functions to specific tissues.
• Prioritize indications with high unmet medical need and meaningful patient impact, with clear go/no-go decision criteria.
• Optimize resource allocation to extend runway and accelerate discovery in prioritized areas.

• In March 2022 Silverback announced a restructuring that discontinued its lead oncology programs to concentrate resources on cHBV and ImmunoTAC discovery efforts.
• Emphasis on tissue-targeted immunomodulation aimed to improve therapeutic index versus systemically distributed biologics or small molecules.
• Program prioritization reflected a shift toward chronic viral disease where long-term local immune modulation could offer transformative benefits.

• Concentration of R&D efforts on discovery-stage ImmunoTAC assets to generate a diversified preclinical pipeline tailored for tissue specificity.
• Redirection of capital and personnel to indications where local immune modulation can address chronic disease burden (e.g., cHBV).
• Rigorous portfolio pruning to preserve cash runway and increase probability of delivering value-driving preclinical/early clinical data.

Silverback Therapeutics, Inc. (SBTX) - Vision Statement

• Scientific excellence: rigorous target validation, translational biomarker strategies, and robust preclinical-to-clinical translation driven by ImmunoTAC™ platform capabilities.
• Patient-centricity: designing locally acting modalities to improve efficacy and safety profiles for patients, with clinical endpoints focused on meaningful outcomes (e.g., functional cure rates for cHBV).
• Ethical governance: adherence to transparent corporate governance, regulatory compliance, and stewardship of capital to advance high-value programs.

• ImmunoTAC™ platform: a proprietary approach to generate tissue-targeted therapeutics intended to concentrate pharmacologic activity at disease sites and limit systemic immune activation.
• Portfolio concentration: in March 2022 Silverback restructured operations, discontinuing its lead oncology programs to redeploy resources toward cHBV and ImmunoTAC discovery efforts-aligning pipeline priorities with areas of high unmet need and anticipated clinical impact.

• Resource optimization: the March 2022 shift prioritized discovery and cHBV programs to extend runway and focus R&D spend on programs with higher probability of addressing large unmet patient populations.
• Clinical and translational metrics: emphasis on measurable biomarkers of local target engagement and safety signals to de-risk clinical development and accelerate go/no-go decisions.

• Therapeutic differentiation: leveraging tissue-targeted design to reduce dose-limiting systemic immune-related adverse events commonly seen with non-targeted immune modulators.
• Patient outcomes: aiming to increase rates of functional cure in cHBV and improve tolerability in immune-oncology indications through localized pharmacology.
