REGYNERA(dia)TION is an international, multicenter, ambispective observational patient registry of adults with recurrent gynecologic malignancies after prior radiotherapy who are treated or planned for reirradiation and/or total ablative strategies as part of routine clinical care. The registry does not assign treatment. Radiotherapy technique, dose, systemic therapy, surgery, metastasis-directed therapy, imaging, and follow-up are selected by the treating multidisciplinary team according to local standards and patient-specific factors. The registry will collect harmonized retrospective and prospective data on disease characteristics, prior radiotherapy, recurrence pattern, reirradiation or ablative treatment exposure, response, progression, survival, severe treatment-related morbidity, fistula events, and patient-reported outcomes where available.

RecruitingNot applicable🇵🇱 PolandLung cancer

In this phase III study, the primary objective is to test with a one-sided significance of 5% whether for the treatment of small cell lung cancer (SCLC) patients, brain MRI surveillance alone is non-inferior in terms of overall survival compared to prophylactic cranial irradiation (PCI) combined with brain MRI surveillance in the entire study population.

RecruitingPhase III🇵🇱 PolandMale onlyProstate cancerMetastatic / advanced

The primary objective of this study is to measure efficacy of saruparib + physician's choice of ARPI compared with placebo + ARPI in men with metastatic hormone-sensitive prostate cancer (mHSPC) who have previously received docetaxel chemotherapy or a prostate-specific membrane antigen (PSMA)-directed lutetium-177 radioligand therapy with no evidence of disease progression and PSA ≥ 0.2 ng/mL.

About the trial

Immunotherapy (IO), such as treatment with anti-PD-1, PD-L1, or CTLA-4 inhibitors, is a rapidly expanding treatment for multiple metastatic cancers with improved survival for certain cancers. However, the optimal duration of immunotherapies is currently unknown. Our hypothesis is that a reduced dose intensity of IO could be as effective as the current standard treatment in term of prevention of the disease progression. If proved right, this study will have a positive medico-economic impact by reduction of the costs associated with the treatment and the toxicity, and an increase of the patients' quality of life.
