Question 1 of 10Pass mark: 80%

Question 1 of 10 Which case information is particularly important when assessing a possible autoimmune flare during tremelimumab treatment?

The baseline autoimmune diagnosis, disease activity, immunosuppressive therapy and similarity of the new phenotype to prior disease Only the patient's tumour histology Only the antibody concentration measured before treatment The absence of any infusion reaction during the first dose

Question 2 of 10 What does the article mean by maintaining two levels of reasoning in tremelimumab pharmacovigilance?

Evaluate CTLA-4-specific biology while also assessing the full clinical regimen as the context in which toxicity occurred Perform separate analyses only and never integrate product-level and regimen-level information Treat every adverse event as either molecular or clinical, but not both Use only aggregate data because individual case assessment cannot address combination therapy

Question 3 of 10 Which follow-up information would most improve assessment of suspected checkpoint-related colitis?

Stool frequency, blood or mucus, infectious studies, imaging or endoscopy, treatment and outcome Only the patient's cancer stage at initial diagnosis Only the antibody batch number The date of the patient's most recent routine vaccination

Question 4 of 10 A report describes 'diarrhoea' during dual checkpoint therapy but provides no stool frequency, infectious work-up or inflammatory assessment. What is the main pharmacovigilance concern?

The broad term may obscure clinically important colitis and prevents adequate assessment of alternative causes and severity The event is automatically non-serious because diarrhoea is a common symptom The report proves that the event was caused by platinum chemotherapy The absence of an endoscopy means the event must be deleted

Question 5 of 10 Why is a biochemical liver-test abnormality alone insufficient to establish immune-mediated hepatitis?

Because infection, underlying liver disease, tumour progression and concomitant medicines may produce similar abnormalities Because liver tests are not relevant to checkpoint inhibitor safety Because immune-mediated hepatitis can only be diagnosed by skin biopsy Because all liver-test abnormalities during immunotherapy are expected and non-serious

Question 6 of 10 Why should exact product and batch information be retained where available?

It supports assessment of hypersensitivity, infusion reactions and potential quality complaints It is needed to determine whether CTLA-4 is expressed on antigen-presenting cells It replaces the need to document clinical symptoms It establishes that all adverse events were caused by the product

Question 7 of 10 Which operational control would best address a common pharmacovigilance failure in tremelimumab cases?

Use structured follow-up that captures organ phenotype, complete combination exposure, alternative causes and delayed events Require all cases to assign the event to one antibody before entering any clinical details Stop case retrieval once tremelimumab administration has ended Replace clinical follow-up with batch information alone

Question 8 of 10 How should time-to-onset analyses handle the limited tremelimumab exposure in the STRIDE regimen?

Use the complete regimen timeline and continue retrieval of delayed events after the final tremelimumab dose Censor all surveillance at the date of the single tremelimumab dose Count only events occurring within the infusion period Use the date of durvalumab initiation as the only relevant exposure date

Question 9 of 10 Which statement best describes endocrine immune-mediated toxicity after checkpoint blockade?

Inflammatory activity may settle while permanent endocrine dysfunction requires long-term hormone replacement Endocrine effects are always transient and require no follow-up after symptom resolution Endocrinopathies are expected only during intravenous infusion Hormone replacement should be omitted from the case outcome because it is not an adverse event

Question 10 of 10 Which pair correctly matches a safety issue with a high-value follow-up element?

Pneumonitis — imaging pattern, infection testing, oxygenation and steroid response Endocrinopathy — only the infusion start time Myocarditis — only stool culture results Cytopenia — only mucosal body-surface involvement
