Filter by:The goal of this open-label randomized, multicenter, comparative phase II trial is to evaluate the efficacy of the immunotherapy, dostarlimab, as first-line treatment for deficient mismatch repair (dMMR)/microsatellite instability (MSI) non-resectable metastatic or locally advanced non-colorectal and non-endometrial cancers compared to the standard of care chemotherapy. Adult patients (aged ≥18 years) with histologically confirmed dMMR/MSI duodenum and small bowel adenocarcinoma, gastric and oeso-gastric junction (OGJ) adenocarcinoma with combined positive score (CPS)<5, pancreatic adenocarcinoma, ampulla of vater adenocarcinoma, adrenocortical carcinoma, carcinoma of unknown primary site, neuroendocrine carcinoma (Grade3) all primary, and soft tissue sarcoma (except Gastro-Intestinal Stromal Tumor) will be included in this study. They will be randomized and treated with either dostarlimab (experimental arm A), or chemotherapy (control arm B). Patients with documented disease progression following the first line chemotherapy (Arm B) may be eligible for crossover to be treated with dostarlimab, with the same schedule as arm A.
The utility of adjuvant chemotherapy in the management of Small Bowel Adenocarcinoma (SBA) remains unproven and awaits the results of a large, global, prospective, phase III, randomised, controlled trial. Across the 830 million population of North America and Europe, there are approximately 3,000 patients with stage I-III SBA every year who would be potentially eligible for such an adjuvant chemotherapy trial. Given the absence of good-quality and evidence-based data, it has been agreed that a trial considering adjuvant chemotherapy versus no chemotherapy was appropriate for patients with stage I-III SBA in whom the oncologist and patient feel that the benefit of adjuvant chemotherapy is uncertain. For those patients with stage I-III SBA who, with their oncologists, feel that the potential benefit of adjuvant chemotherapy is certain (and hence are not willing to accept randomisation to the 'no chemotherapy' arm), a randomisation between single agent fluoropyrimidine versus doublet fluoropyrimidine and oxaliplatin chemotherapy will be offered. Tumour stage will be used as a stratification factor. Those patients who do not consent to be randomised will be offered registration to allow collection of demographic, clinicopathological and survival data, thereby making optimal use of the rare patient population available. In addition, archival Formalin Fixed Paraffin Embedded (FFPE) tissue and contemporaneous venous blood samples will be collected from every registered patient to allow molecular profiling and future translational research. A questionnaire about underlying risk factors (e.g. Crohn's disease, coeliac disease, Lynch syndrome etc) will be completed along with the other collected data on all registered patients.
