Medical research participation percentages haven't always been fully representative of a given demographic.

The goal is to find out which aspects of a clinical study may make it more difficult for patients to take part or see it through.

The data will be evaluated through different demographic lenses and identify trends that could help improve the experience of future mesothelioma patients during clinical trials.

Inclusion Criteria:

• Must have a medical diagnosis of mesothelioma that has been confirmed by a physician.
• Aged ≥ 18 years old and ability to provide written informed consent obtained prior to participation in the study and any related procedures being performed.
• Willing and able to comply with scheduled visits, treatment schedule, laboratory tests and other requirements of the study.

Exclusion Criteria:

• Pregnant or lactating woman
• Patients with any significant history of non-compliance to medical regimens or with inability to grant a reliable informed consent.
• Known medical condition that, in the investigator's opinion, would increase the risk associated with study participation or study drug(s) administration or interfere with the interpretation of safety results
