Study was stopped due to negative preliminary analysis, slow recruitment (105 patients over 2,5 years), lack of funding, need for more centers, and the changing treatment landscape (approval of ICIs in combination with other cancer treatments).

The goal of this prospective, multicentre study is to investigate short- and long-term cardiovascular effects in cancer patients treated with immune checkpoint inhibitors (ICIs).
The main question[s] it aims to answer are:
Participants will be closely monitored by performing the following additional visits and testing:
The increasing use of immune checkpoint inhibitors (ICIs) in the treatment of both advanced and early stages of various malignancies has resulted in a substantial increase in the incidence of cardiovascular immune related adverse events (irAEs). The current guidelines are based on anecdotal evidence and expert opinions due to the lack of solid data and prospective studies. Therefore, cardiac monitoring, in patients receiving ICIs, is often not implemented by oncologists as many questions remain unanswered. Hence, the urgent need to investigate the possible short and long term cardiovascular effects of ICIs.
The investigators developed a multicentre, prospective study in which patients with a solid tumour eligible for ICI treatment will be enrolled. The study exists of routine investigations of blood parameters (troponin and (N-terminal) brain-type natriuretic peptide levels in particular) and a thorough cardiovascular follow-up on fixed time points during a period of two years. The cardiovascular follow-up consists of continuous remote patient monitoring, routine cardiology consultations including electrocardiograms, transthoracic echocardiograms, CT-scans for calcium scoring and non-invasive endothelial function tests. Associations between these blood parameters and short and long term cardiovascular irAEs will be statistically analysed.
This project will allow for a better estimate of the incidence of both short and long-term cardiovascular irAEs in a 'real world' patient population receiving ICIs. If the investigators are able to accurately predict and detect short- and long-term cardiovascular irAEs in an early (and subclinical) stage by correct implementation and interpretation of existing cardiac markers, they could be managed early on in a more effective manner.

| The incidence of an elevated hs-TnT above the ULN if the baseline value was normal; or 1.5 ≥ times baseline if the baseline value was above the ULN within the first three months of treatment. The maximum measured value will be taken into account. | For the primary endpoint, the cumulative incidence of troponin elevation will be calculated with death as a competing risk. Cumulative incidences and corresponding 95% confidence intervals will be reported and a cumulative incidence plot will be used to visualize the results. | Preliminary analysis once 50 patients have reached their 3-month cardiac follow-up visit and 3 months after last patient is included. |

| Chest Computed Tomography (CT) without contrast | Diagnostic Test | Calcium score. This will be performed at baseline, 12 and 24 months. The scans at 12 and 24 months will be combined, if possible, with standard of care scans for cancer treatment. |
|
|
| Non-invasive endothelial function tests | Procedure |
This aspect of the study will only be performed in the patients included by the Antwerp University Hospital due to organizational/practical issues. |
|
|
| Electrocardiogram | Procedure | An ECG will be taken prior to each ICI cycle during the first three months of treatment. |
|
|
| Extra serum sample (7.5 mL) | Diagnostic Test | An extra serum sample will be taken at baseline, 3, 6, 12, 24 months and in case of sudden cardiac problems. This will subsequently be analysed to determine high-sensitivity troponin I, high-sensitivity troponin T and NT-proBNP. |
