Rare cancers, defined by an incidence of fewer than 6 cases per 100,000 persons per year, constitute nearly 25% of adult malignancies. They are associated with poor patient outcomes due to incomplete biological understanding and inadequate representation in clinical trials. To address this gap, the DKFZ/NCT/DKTK MASTER (Molecularly Aided Stratification for Tumor Eradication Research) program, developed by NCT and DKFZ, integrates whole-genome/exome sequencing (WGS/WES), RNA sequencing (RNA-seq), and genome-wide DNA methylation profiling to inform clinical decision-making in patients with advanced rare cancers. This approach has demonstrated significant improvements in overall response rates (ORR) in 24% and disease control rates (DCR) in 55% of cases, with a progression-free survival (PFS) ratio greater than 1.3 in 36% of patients.
The randomized, multi-basket, phase II, Italian multicenter ROME study conducted among pretreated patients with metastatic cancer, demonstrated that targeted therapy guided by comprehensive genomic profiling and molecular tumor board (MTB) recommendations significantly improved overall response rate and progression-free survival. Additionally, the study revealed a substantial long-term PFS benefit extending to 12 months and beyond. Although the toxicity profiles differed between the targeted therapy and standard-of-care groups, the incidence of adverse events was comparable. These findings, reported at the ESMO Congress 2024, emphasize the pivotal role of MTBs in advancing precision oncology through a tumor agnostic, molecularly guided therapeutic approach.
The objective of the randomized, multicentric, diagnostic RATIONALE trial is to evaluate the efficacy of molecularly guided treatment versus standard treatment in patients with rare cancers by comparing progression-free survival (PFS) between the two arms: an immediate molecular profile-informed treatment arm (MPI arm) and a standard treatment arm with molecular profile-informed treatment upon progression or intolerable toxicity after standard therapy (MPP arm).
Patients with rare epithelial and mesenchymal neoplasms are evenly randomized in a 1:1 ratio to either the MPl arm or MPP arm. Comprehensive molecular profiling includes WGS and RNA-seq for both arms. A multidisciplinary MTB evaluates these molecular profiles and provides clinically relevant management recommendations, including diagnostic reevaluation, genetic counseling, and molecularly informed treatment options. Recommendations may include matching patients to molecularly stratified clinical trials or - if no suitable clinical trials can be identified - coordinated applications will be provided for off-label use in routine clinical care. The primary efficacy endpoint is progression-free survival (PFS), whereas secondary endpoints are overall survival (OS), overall response rate (ORR), disease control rate (DCR) after three and six months, and patient-reported outcomes (PROs).
Based on data from the MASTER cohort, it is anticipated a median PFS of three months with treatment selected by the physician's discretion. Drawing on findings from the CRAFT trial (ClinicalTrials.gov: NCT04551521), MTB-guided treatment is expected to positively impact the primary endpoint with a hazard ratio (HR) ranging from 0.4 to 0.6. Assuming 30% implementation rate of MTB recommendations, a sample size of 756 eligible patients will be required to demonstrate a significant improvement in PFS with immediate MTB guided treatment, yielding an HR of 0.5 for the MPI arm and overall study HR of 0.7862. The calculation is based on a type 1 error of 5% and a statistical power of 90%. Considering a conservative estimate that that 20% of patients will not be evaluable, the total rounded required sample size is 946 patients.

Inclusion criteria
Exclusion criteria
Time frame: 48 months
Progression free survival (PFS) measured from (i) start of the genomics-guided treatment or (ii) standard-of-care treatment started after randomization until radiographic disease progression or death, whatever occurs first. Patients alive and progression-free are censored at last tumor measurement according to radiographic and disease-specific assessment. For patients undergoing active tumor therapy before randomization (bridging treatment), PFS is measured from (i) start of the genomics-guided treatment or (ii) standard-of-care treatment started following the bridging treatment until radiographic disease progression or death,
whatever occurs first.
Time frame: 48 months
Overall Survival (OS), the time from randomization until death from any cause. Patients without event are censored on the last date of follow-up.
Time frame: 48months
rPFS, defined as the time from randomization to time of progression of the disease or death from any cause, whatever occurs first.
Time frame: 48 months
mrPFS, defined as the time from release of MTB report to time of progression of the disease or death from any cause, whatever occurs first.
Time frame: 48 months
Paired Progression Free Survival (PFS ratio) observed with genomic guided treatment (PFS2) and Progression Free Survival observed directly before genomics-guided treatment (PFS1)
Time frame: 6 months
Overall Response rate (ORR), defined as the proportion of patients with complete response (CR) or partial response (PR) as assessed per RECIST v1.1 at 3 and 6 months after start of the recommended therapy is analyzed.
Time frame: 6 months
Disease Control Rate (DCR), defined as the proportion of patients with CR, PR or stable disease (SD) as assessed per RECIST v1.1. DCR at 3 and 6 months after start of the recommended therapy is analyzed.
Time frame: 6 months
HRQoL, measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) as presented in patient-reported outcomes.
Time frame: 3 months
MTB recommendation rate, defined as the proportion of patients who receive therapeutic recommendations in the MTB
