Brief Summary:
The IMRD study is a single-centre, prospective observational study which will investigate the rate of ctDNA (circulating tumor DNA) detection from the start of adjuvant therapy following curative-intent surgery. The study will include patients of age 18 years old or older, who provided informed consent. Eligible patients are affected by one of the following non-metastatic resected tumors: i) breast cancer (BC), ii) non-oncogene addicted (EGFR/ALK-wild type) non-small-cell lung cancer (NSCLC), iii) high-risk and very high-risk prostate cancer, iv) high-grade serous ovarian cancer (HGSOC), and v) gastric cancer. Eligible patients will undergo surgery and receive adjuvant treatment(s) as per standard guidelines. Patients who underwent neoadjuvant treatments and had a complete pathological response (i.e., no residual tumor at surgery following neoadjuvant treatments) will not be eligible for the present study.
During adjuvant treatment and following its conclusion, patients will be subjected to instrumental monitoring, as per standard guidelines and clinical practice. For eligible patients, a baseline plasma sample will be collected at the time of surgery (feasibility window) and prior to the start of adjuvant treatments (not prior to 28 from the date of surgery) for assessing the detection of ctDNA. Afterwards, plasma samples will be collected at 3, 6 and 9 months from the start of postoperative adjuvant treatments. For patient specific monitoring, a tumor-informed targeted sequencing panel, using tumor-specific mutations detected with WES, will be employed to gather the most sensitive diagnostic platforms, mitigating the risk of negative cases. At 6 months or upon positive ctDNA detection, either a thoracic-abdominal-pelvic or total-body CT scan will be performed to exclude the presence of overt metastatic disease. All patients included in the study will be monitored with longitudinal ctDNA assessment until one-year or follow-up or until the radiological detection of metastatic disease, whichever will occur first. Additional follow-up will be carried outside the IMRD study and will follow standard clinical protocols and schedules. Being an observational study, no treatment intervention will be applied as per protocol based on the detection or absence of ctDNA. For conducting exploratory analyses, the primary tumors will be retrieved and subjected to WES, and the study will aim to detect molecular tumor variables associated with a lack of ctDNA clearance following curative-intent treatment interventions.
The study will be conducted in 2 phases. The first phase aims at verifying the feasibility and sustainability of such approach, based on the identification of at least 15% positive patients. This phase is predicted to be completed within 2 years, and is the object of the present application. If the first endpoint is achieved, we will expand the study to include the co-primary endpoint, which aims at estimating the fraction of patients with persistent ctDNA 6 months post-surgery despite adjuvant therapy.
