Filter by:Phase 2, open-label, multicenter, randomized study comparing the safety and efficacy of personalized ultra-fractionated stereotactic adaptive radiotherapy (PULSAR) combined with immune checkpoint inhibitor (ICI) immunotherapy (PULSAR-ICI) + IMSA101 and PULSAR-ICI alone in patients with NSCLC or RCC
In recent years, the scientific community has recognized the need to differentiate between poly- and oligo-metastatic disease (OMD) in oncology due to their distinct clinical and biological behavior. The definition of "true" and good-prognosis OMD is necessarily retrospective, as many patients initially considered oligo-metastatic develop poly-metastatic disease within one year. The PREDICTION study is a prospective, observational, and monocentric investigation. The study has two primary objectives. The first one is descriptive and aims to determine the prevalence of specific biological characteristics in OMD derived from gastrointestinal tract neoplasms (colon, stomach, biliary tract, exocrine glands of the digestive tract). These biological characteristics include genetic landscape and T lymphocyte infiltrate of the primary tumor and/or metastases. Genetic assessment will be done on formalin-fixed paraffin-embedded (FFPE) tissues or liquid biopsies with the Oncomine Solid Tumour DNA kit (Thermo Fisher Scientific, Waltham, MA, USA). Data analysis will be performed using the Torrent Suite Software v5.0 (Thermo Fisher Scientific). The analysis of T lymphocytes will be conducted through immunohistochemistry (IHC) in primary and or metastatic tissues (if available). The second co-primary objective aims to identify OMD through the prognostic effect of a score designed ad hoc. It is tested in a single pathology, namely in patients with metastatic colorectal cancer. A score is constructed based on the following characteristics, with possession of all characteristics (3+) constituting the full score: a primitive/metastasis genetic concordance >80% = 1 point; high T-lymphocyte infiltration GRZB+ (>10 cells/mm2) in the primary tumor and/or metastases (where tissue is available) = 1 point; absence of clonal evolution favoring specific key-driver genes = 1 point. The hypothesis is that patients with true OMD (score 3+) have a significantly lower rate of progression at one year, defined as recurrence after radical surgery or progression (in oligometastatic patients who are not candidates for upfront definitive local treatment) based on RECIST v 1.1 criteria since enrollment in the study, compared to those with false OMD who subsequently develop polymetastatic disease. The treatments will be chosen at the discretion of the referring Oncologist, in multidisciplinary sessions, according to normal clinical practice. The sample size was determined using a two-sided test of difference between proportions to evaluate the statistical significance of the difference in recurrence within 1 year. For this purpose, the following scenario was considered: a reasonable probability of the simultaneous occurrence of the 3 factors in true OMD (score 3+) of 60%; a recurrence rate of 20% for true OMD (score 3+), and 80% for false OMD (score <3+). With a significance level of α=0.05, a test power of 90%, and a Fisher exact test, the required number of patients to be enrolled is 32, to be recruited over an expected period of 2 years.
This is a randomised prospective monoinstitutional study comparing radiosurgery at a total dose up to 24 Gy to five fraction stereotactic radiotherapy with simultaneous integrated boost (SIB) up to 50 Gy for the treatment of bone metastases in oligometastatic cancer treated with radical intent. At the end of the first 12 months from the start of the study an interim analysis will be performed taking into account all major endpoints for an initial evaluation of the study , with only an observational purpose, without subsequent protocol changes.
A prospective, observational study that assesses the clinical feasibility of ctDNA-based liquid biopsy in patients with oligometastatic NSCLC receiving surgery.
The goal of this phase II clinical trial is to explore the efficacy and safety of anti-PD1 combined with stereotactic body radiation therapy (SBRT) for patients with oligometastatic esophageal squamous cell carcinoma. Participants will receive anti-PD1 and SBRT to the metastatic lesions which are amenable to the delivery of SBRT after 4~6 cycles of systemic chemotherapy and anti-PD-1.
TAORMINA is an international, multicentre, randomised phase 3 trial for patients with oligometastatic breast cancer (OMBC) that will be allocated to combined stereotactic ablative radiotherapy (SABR) + systemic therapy (investigational arm) versus systemic therapy alone (control arm) as 1st line therapy.
The aim is to investigate whether the addition of short-term androgen deprivation therapy (ADT) during 1 month or short-term ADT during 6 months together with an androgen receptor targeted therapy (ARTA) to metastasis-directed therapy (MDT) significantly prolongs poly-metastatic free survival (PMFS) and/or metastatic castration-refractory prostate cancer free survival (mCRPC-FS) in patients with oligorecurrent hormone sensitive prostate cancer.
Standard Maintenance Therapy versus Local Consolidative Radiation Therapy and standard maintenance therapy in 1-5 sites of OligoMetastatic Non-small cell lung cancer (NSCLC): A Phase III Randomized Controlled Trial
A Phase II randomized controlled trial of TKI Alone versus TKI and Local Consolidative Radiation Therapy in oncogene driver mutated oligo metastatic Non-small cell lung cancer patients.
To investigate the prognostic and predictive value of plasma HPV (pHPV) prior, during and after induction chemotherapy (ICT) in locally advanced squamous cell carcinoma of the anus (SCCA) or synchronous metastatic SCCA patients treated with ICT prior to definitive (chemo)radiotherapy ((C)RT) according to multidisciplinary team (MDT) conferences based decisions. Further to investigate the use of pHPV measurements and other relevant markers for prediction of response and survival after ICT prior to definitive (C)RT.
