Background
Information on this page is provided to help sponsors understand the reporting requirements for individual case safety reports (ICSRs) contained in the Pharmacovigilance Guideline.
What to report
Report valid ICSRs of all serious adverse reactions to the New Zealand Pharmacovigilance Database. This includes ICSRs where the company does not agree with the reporter's causality assessment.
Valid ICSRs must contain the following four mandatory items:
- An identifiable reporter
- An identifiable patient
- A suspect medicine
- A suspect reaction.
How to report
Choose one of the methods shown in Table 1 to report valid serious ICSRs.
| Method of reporting | Directions |
|---|---|
| Online via the New Zealand Adverse Reaction Reporting Form
with
CIOMS attachment (Preferred) |
New Zealand Adverse Reaction Reporting form:
https://pophealth.my.site.com/carmreportnz/s/ Complete the following sections of the webform only:
|
| Email CIOMS form to carmreport@health.govt.nz | |
| Electronic file transfer system (EFT) | Submit CIOMS form via Medsafe's electronic file transfer system (EFT). EFT information can be located on the Medsafe website. |
When to report
Submit valid ICSRs of serious adverse reactions within 15 calendar days of receipt (Table 2). The clock for reporting starts (ie, Day 0) when the New Zealand sponsor or contracted vendor receives the information.
| Adverse reaction report | Report as soon as possible and no later than |
|---|---|
| Initial reports of serious adverse reactions | 15 calendar days |
| Follow-up reports when additional medically relevant information is
received for a previously reported case. Note: Please indicate that it is a follow-up report and quote the original report number so they can be linked. |
15 calendar days |
Specific situations
Table 3 provides guidance on reporting valid ICSRs in certain situations.
| Specific situation | Valid ICSRs requiring reporting |
|---|---|
| Lack of therapeutic effecta | Medicine used for an approved indication resulting in a lack of therapeutic
effect which was serious for the individual. Examples include vaccines, contraceptives, and antibiotics (with sensitivity in in vitro testing). Use clinical judgement when considering reporting other cases of lack of therapeutic effect. |
| Misuse or abuse | The misuse or abuse caused a serious adverse reaction. |
| Off-label use of an approved medicine | The off-label use resulted in a serious adverse reaction. |
| Unapproved medicines (Section 29) | There was an unexpectedb serious adverse reaction. |
| Unapproved medicinal cannabis products | There was a serious adverse reaction. |
| Medication error | The medication error caused a serious adverse reaction. |
| Overdose or occupational exposure | The overdose or occupational exposure caused a serious adverse reaction. |
| Quality defects | Serious adverse reactions after a quality defect has been investigated and is not confirmed. See guideline for more information on reporting quality defects. |
| Period after suspension, revocation of consent to distribute, or company-initiated removal from the market | Report unexpectedb serious adverse reactions up to the expiry date of the last distributed batch in New Zealand. |
| Post authorisation safety studies | There was a serious adverse reaction considered related by the principal investigator or sponsor. |
Notes:
- For vaccines, cases of a lack of prophylactic efficacy may highlight signals of
reduced immunogenicity in a subgroup of vaccines, waning immunity, or strain replacement.
For antibiotics, a lack of therapeutic effect may indicate newly developing resistance, making further study necessary. Antibiotics used in life-threatening situations where the medicine was not appropriate for the infective agent do not require reporting to Medsafe.
A lack of therapeutic effect may also be related to, but not necessarily considered to be, a quality issue. - An unexpected adverse reaction is an adverse reaction that is not currently listed in the Company Core Data Sheet.
Clinical trials
See Table 4 for guidance on what to report and the timeframe for reporting. Report using one of the methods in Table 1, or Ethics RM.
| Type of clinical trial | What to report | Report as soon as possible and no later than |
|---|---|---|
| SCOTT/GTAC trials | SUSARs that are life-threatening or fatal only | 15 calendar days |
| Other clinical trials | Serious adverse reactions | 15 calendar days |
