This study will explore the ability of patients on first line combination immunotherapy to sample cytokines at home. The data from this study will be used to evaluate the feasibility of in-home testing and the ability to analyse patients cytokine profiles retrospectively to help feed the development of further studies.
Patients will be informed of the study and given a minimum of 24 hours to consider. Once consented patients will enter the study where they will take cytokine samples at home over a 12 week period.

RECRUITINGPatient adherence to protocol defined DBS time points.
the number of DBS samples successfully collected against the number of total expected samples
Time frame: 12 months
Number of in-home DBS samples passing quality assurance checks in patients receiving CPI therapy by multi-cytokine ELISA.
the number of DBS samples passing quality assurance checks against the number of DBS samples successfully collected.
Time frame: 12 months
Compare cytokine concentrations by DBS sampling and intravenous blood sampling by multi-cytokine ELISA.
The changes of cytokine concentrations will be estimated by the log-ratio of cytokine concentrations measured at two time points. The trend of cytokine concentration during treatment will be estimated by fitting a linear regression model based on all cytokine concentrations collected during treatment.
Time frame: 12 months
