Adaptive Design for a Confirmatory Basket Trial in Multiple Tumor Types Based on a Putative Predictive Biomarker

Area of Science:

• Oncology
• Clinical Trial Design
• Translational Research

Background:

• Tumor classification is increasingly molecular, leading to targeted therapies.
• Molecular subtypes create rare disease subsets, complicating traditional clinical trial enrollment.
• Basket trials allow pooling patients with shared molecular targets across different cancer histologies.

Purpose of the Study:

• To explore qualitative designs for confirmatory basket trials.
• To address challenges in developing targeted therapies for rare molecular subtypes.
• To enhance patient access to novel treatments in niche oncological indications.

Main Methods:

• Consideration of qualitative research methodologies for confirmatory basket trial design.
• Focus on pooling patient cohorts based on shared molecular alterations across diverse histologies.
• Evaluation of regulatory pathways for accelerated approval using surrogate endpoints.

Main Results:

• Confirmatory basket designs can facilitate development and approval for rare indications.
• These designs improve patient access to novel targeted therapies.
• Combining trials in a basket approach can reduce development costs and aid regulatory review.

Conclusions:

• Qualitative designs offer a viable strategy for confirmatory basket trials.
• Basket trials are crucial for advancing targeted therapy development in rare molecular subtypes.
• This approach enhances regulatory evaluation of risk-benefit for niche cancer indications.
