Summary
The MULTISARC trial assesses if next-generation sequencing (NGS) is feasible for metastatic soft-tissue sarcomas (STS). This study aims to determine if an NGS-guided strategy improves patient outcomes in rare cancers.
Area of Science:
- Oncology
- Genomics
- Clinical Trials
Background:
- Soft-tissue sarcomas (STS) are rare, heterogeneous tumors with over 70 subtypes.
- Next-generation sequencing (NGS) offers a personalized approach to identify driver mutations for tailored cancer treatment.
- Current STS treatment often follows a standard paradigm, lacking individualization based on molecular profiles.
Purpose of the Study:
- To evaluate the feasibility of conducting next-generation sequencing (NGS) in a large cohort of metastatic STS patients within a clinically relevant timeframe.
- To determine if a therapeutic strategy guided by NGS improves outcomes for participants with advanced soft-tissue sarcomas.
- To provide high-level evidence for integrating NGS into routine clinical practice for advanced STS.
Main Methods:
- A randomized, multicentre, phase II/III trial (MULTISARC) involving 960 participants across 17 centers.
- Participants are randomized 1:1 to either an experimental arm receiving NGS or a standard care arm ('No NGS').
- NGS feasibility is defined by timely, interpretable results and a multidisciplinary tumor board recommendation within 7 weeks.
Main Results:
- The study expects a feasibility rate exceeding 70% for NGS implementation.
- Participants in the 'No NGS' arm failing treatment can switch to the NGS arm upon investigator request.
- The trial design is inspired by umbrella and biomarker-driven studies, facilitating adaptable treatment strategies.
Conclusions:
- The MULTISARC trial is designed to generate robust evidence for the widespread adoption of NGS in advanced STS care.
- Implementing NGS can potentially shift STS treatment from a one-size-fits-all approach to a patient-specific therapeutic strategy.
- This study supports the integration of molecular profiling into routine oncological practice for rare cancers like STS.
