Attention and Interpretation Modification (AIM) for Fear of Cancer Recurrence: An Intervention Development Study

The purpose of this study is to test, customize, and personalize a mobile app-based intervention program in order to help rare and breast cancer survivors cope with fears of cancer recurrence.

Treatment Guided by Comprehensive Genome and Transcriptome Analysis Versus Standard of Care in Advanced Rare Cancers

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.

Genomic Investigation of Unusual Responders

Studies have shown that tumors from the same patient may respond very differently to the same therapeutic agents. This study aims to investigate the genetic basis of tumors that respond abnormally well or poorly to therapeutic agents in an effort to understand the fundamental genetic basis of this response. The present protocol seeks to retrospectively perform Exome, next-generation (DNA) sequencing and/or other molecular techniques on tumor samples to identify the genetic basis of a patient's exceptional response to chemotherapy.

Registry Study on Rare Cancers in Korea

This study aims to determine the participation rate of patients with registered rare cancers in clinical research.

Ontario-wide Cancer TArgeted Nucleic Acid Evaluation

Substantial progress has been made in the treatment of cancer through the use of targeted therapies, but what works for one patient might not work for another patient. Certain drugs are now being developed that target specific molecules in the body that are believed to be part of the disease. Biomarkers are specific characteristics of the cancer that may help provide prognostic information (e.g. how well patients will be regardless of the treatments given) or help predict sensitivity or resistance to a specific treatment. The study will collect archival tumor samples (previously collected biopsy or surgical tumor samples) to provide biomarker data about a patient's cancer, which may help their physicians to identify which clinical trials of new drug treatments may be most appropriate for the patient in the future and may also guide the use of approved treatments that may potentially benefit the patient. Another goal of this study is to develop a province-wide registry of targeted gene sequencing testing results that will be made available to cancer researchers. Additional tumour tissue and blood samples collected from all study participants will also be stored in a biobank at the Ontario Institute for Cancer Research for future research. The study will also look at linking data from this study to other health care databases to further collect information about the health care the patients received, including medical tests, clinic visits, or procedures both before and after participating in this study. Having more information about patient health to relate to the DNA sequences may provide new insights into cancer and its treatment.

A Phase II Study on Adjuvant Vaccination with Dendritic Cells Loaded with Autologous Tumor Homogenate in Resected Stage IV Rare Cancers.

Single-arm, monocentric trial to assess safety and immunological efficacy of adjuvant vaccination with autologous dendritic cells loaded with autologous tumour homogenate after curative resection for stage IV rare cancers (In Head/Neck tumors (H\&N), NEuroendocrine Tumors (NET) and Soft Tissue Sarcomas (STS).
