Open-label, phase II, basket trial. This trial is a screening program for abemaciclib efficacy in multiple platinum-resistant tumour types by using metabolic imaging (PERCIST) and RECIST v1.1 criteria.
Based on the rate of FDG-avidity and the absence of deactivation of the Rb gene function in more than 95% of cases, we propose to define 5 tumour types of interest in a preliminary stage:
- Platinum-refractory esophageal adenocarcinoma (ADC)
- Platinum-refractory esophageal squamous cell carcinoma (SCC)
- Platinum-refractory cholangiocarcinoma
- Platinum-refractory and progressive after immunotherapy urothelial cancer
- Platinum-refractory endometrial cancer

In various solid tumour types FDG-PET/CT has been shown to identify treatment-refractory diseases with a high negative predictive value (NPV) through a whole-body quantitative assessment of treatment-induced changes in tumour glucose uptake soon after treatment initiation, before any structural changes are observed. Progress in the standardisation of FDG-PET/CT imaging and response analysis now allow its use in multicentric trials opening the possibilities for trials where treatment allocation will be based on early metabolic response. MiMe has been built on the assumption that a medication which does not induce any metabolic changes in a given clinical setting is unlikely to induce a significant benefit and does consequently not deserve further investigation as a single agent in this setting.
MiMe, by assessing metabolic response early during the treatment course, will hopefully provide useful information about the drug activity in various cancer types, and about mechanisms of resistance through a potential ambitious translational research program with serial collection of circulating-tumour DNA (ct-DNA).

This study contains 2 stages; during the 1st stage, a maximum of 17 patients will be enrolled in each tumour type cohort. After 13 evaluable patients have been enrolled, an interim analysis will be performed. If 3 or more patients are seen to have experienced a treatment success, then the cohort will pass into the 2nd stage in which a maximum of 20 more patients are enrolled. If 2 or less patients are seen to have experienced a treatment success, then that cohort will be closed and will not proceed into the 2nd stage.
Subjects will receive 200 mg of abemaciclib orally, twice a day, during cycles of 28 days each. The subject will undergo: A baseline FDG-PET/CT and a baseline CT scan and A blinded early FDG-PET/CT at D14 +/- 2 days of study treatment.
A treatment success is defined as a patient who has metabolic response according to PERCIST with a response cut off set at 15% at the early FDG-PET/CT and a morphological disease control after 2 cycles measured by RECIST v1.1.
Subjects will receive 200 mg of abemaciclib orally, two times a day, during cycles of 28 days each. An early FDG-PET/CT will be performed at cycle 1 day 14 to search for any new lesions.
