- Advanced AI and tech-enabled strategies to model feasibility and identify, enroll and retain patient populations with specific subtypes or biomarkers or rare forms of breast cancer
- A patient-centric model that incorporates patient needs and perspectives throughout the clinical trial to ease the burden of participation and improve engagement, adherence and outcomes
- An Oncology Center of Excellence that integrates commercial, medical, patient, payer and regulatory insights into early clinical trial design to ensure every protocol is aligned with real-world value
Let’s talk about your next breast cancer clinical trial.
Breast cancer clinical trials face unique challenges due to the disease’s biological complexity, heterogeneity, diverse patient population and rapidly evolving treatment landscape. The biological heterogeneity of breast cancer creates opportunities to tailor interventions across the treatment continuum, but also introduces complexity in clinical trial design, requiring nuanced eligibility criteria and stratified enrollment strategies that can slow recruitment and complicate statistical analysis.
Trials must account for multiple molecular subtypes, which can limit eligible participants and complicate study design. Recruitment is often hindered by restrictive eligibility criteria, lack of awareness and underrepresentation. Additionally, the fast pace of therapeutic innovation can render control arms outdated, requiring adaptive trial designs that are resource-intensive and statistically demanding.
Innovative trial designs in breast cancer research are reshaping how treatments are tested and personalized.
- Adaptive trials, like I-SPY 2, allow modifications during the study based on early results, improving efficiency and responsiveness.
- Basket and umbrella trials focus on genetic mutations or molecular subtypes, enabling targeted therapies across or within cancer types.
- Platform trials combine these approaches under a single protocol, streamlining the evaluation of multiple treatments.
Additionally, pragmatic trials and real-world evidence studies assess therapies in everyday clinical settings, enhancing relevance. These designs accelerate drug development and support precision medicine in breast cancer by tailoring interventions to individual tumor biology.
