Identifying adverse events

A system for identifying an adverse event likely to occur in respect of a subject to receive or having received immunotherapy treatment, the system comprising:

• a memory comprising instruction data representing a set of instructions;
• and
• a processor configured to communicate with the memory and to execute the set of instructions, wherein the set of instructions, when executed by the processor, cause the processor to:
• obtain a subject profile associated with the subject, wherein the subject profile comprises at least the age of the subject and the gender of the subject;
• obtain drug administration data associated with the subject, wherein the drug administration data comprises details of a drug or drugs that have previously been administered to the subject, details of a drug or drugs that are currently being administered to the subject and/or details of a drug or drugs that are due or planned to be administered to the subject;
• obtain medical data associated with the subject, wherein the medical data comprises at least one of a clinical history associated with the subject and a genetic profile associated with the subject;
• obtain toxicity data, wherein the toxicity data comprises (i) data relating to known toxicities associated with the drugs (ii) data relating to toxicities likely to occur in subjects having medical data relevant to the subject and/or (iii) data relating to toxicities likely to occur in subjects of an age range and gender relevant to the subject;
• determine, based on the subject profile, the drug administration data and the toxicity data, a first set of adverse events likely to occur in respect of the subject;
• determine, based on the subject profile, the medical data and the toxicity data, a second set of adverse events likely to occur in respect of the subject;
• identify at least one indicator associated with at least one determined adverse event;
• and
• output the at least one indicator to a user interface configured for communication with the processor such that the at least one indicator is detectable by a medical test to determine an occurrence of the least one determined adverse event.
