Adverse Event and Product Complaint Reporting

Part of Amgen's mission to serve patients includes collecting, reviewing and reporting all Adverse Events (AEs), Other Safety Findings (OSFs), and Product Complaints (PCs) information associated with the use of Amgen's investigational and marketed products. Please refer to our Adverse Event and Product Complaint Reporting Policy for additional information

It is Amgen's policy to comply with all regulations and laws worldwide relating to reporting Adverse Events, Other Safety Findings and Product Complaints (collectively known as Reportable Events). Individuals subject to this policy are required to report all Reportable Events within one business day of learning of it.

Adverse Events (AE)

An AE is any untoward medical occurrence in a patient administered an Amgen product and which is not necessarily caused by the Amgen product. An AE can therefore be any unfavorable and unintended sign (e.g., an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, combination product, or medical device, whether or not considered related to the product. This includes:

  • Any clinically significant worsening of a pre-existing condition; or
  • An AE that has been associated with the discontinuation of the use of a product.

Other Safety Findings (OSFs)

The following are considered Other Safety Findings regardless of whether they are associated with an AE and they must be reported to Amgen:

  • Use of an Amgen product while pregnant and/or breast feeding. This includes pregnancies in women whose sexual partner took, or is taking, an Amgen product.
  • Medication errors
  • Overdose
  • Underdose
  • Misuse is defined as the intentional improper use of a medicinal product, combination product or medical device not in accordance with the authorized product information.
  • Abuse
  • Addiction
  • Transmission of an infectious agent through a contaminated Amgen product
  • Accidental Exposure
  • Occupational Exposure
  • Lack or loss of therapeutic efficacy
  • Missed dose, if not taken prior to the next scheduled
  • Unexpected therapeutic benefit
  • Reports of patient "death" after exposure to Amgen's product where no other details are provided (e.g., fatal outcomes)
  • Off-label use of an Amgen product defined as the intentional use of a product in a manner inconsistent with the locally approved label, i.e., a different dose, use, indication or patient population than that approved in the local label. U.S. Commercial field staff are not required to report off-label use unless the off-label use is associated with an AE. However, US Commercial field staff must report all other AEs, PCs and OSFs irrespective of whether the event is from on-label or off- label use.

Product Complaints (PC)

Any written, electronic or oral communication that alleges deficiencies related to the identity, quality, durability, reliability, safety, effectiveness, or performance of a drug, combination product, or device after it is released for distribution to market or clinic by either: (1) Amgen or (2) distributors or partners for whom Amgen manufactures the material. This includes all components distributed with the drug, such as packaging, drug containers, delivery system, labelling, and inserts.

Use Error is a situation in which the outcome of device use was different than intended, but not due to malfunction of the device. The error may have been due to a poorly designed device, or it may have been used in a situation that promoted incorrect usage.  Use errors are considered product complaints

What to Report

When submitting a Reportable Event, you will need to have the following information ready:

  • The identifiable patient:
    • The person who has taken or been administered the product (e.g. age, gender, etc.), in compliance with local privacy laws.
  • An identifiable reporter:
    • The source that reported the event (e.g. patient, health care provider, friend, etc.), in compliance with local privacy laws.
  • The medicinal product:
    • Amgen product name, indication and lot number if known.
  • The reportable event:
    • Description of the AE, other safety finding or product complaint.

Please report as much relevant information as possible. You should still report even if you do not have all the required information.

It does not matter whether the Reportable Event is thought to be caused or not thought to be caused by taking an Amgen product – all AEs, OSFs and PCs must be reported. Report it, even if it is listed in the approved company prescribing information as a possible side effect. When in doubt, report it.
