Primary

MeasureTime frameDescription
Safety information (Adverse Event)14 days from the initiation of tolvaptan sodium phosphate treatmentAny untoward medicinal occurrence in a patient or clinical study subject administered a Medicinal Product and which does not necessarily have a causal relationship with this treatment (see Annex Ⅳ, ICH-E2A Guideline). An Adverse Event can therefore be any unfavorable and unintended sign (e.g. abnormal laboratory finding), symptom, or disease temporally associated with the use of a Medicinal Product, whether or not it is considered causally related to the Medicinal Product.
Number of Special Situations14 days from the initiation of tolvaptan sodium phosphate treatmentCollecting any Situations related to the use of an Otsuka product which may or may not be associated with an adverse event: * Maternal (pregnancy and breastfeeding) or paternal (via semen) exposure; * Exposure during breastfeeding; * Overdose/Incorrect dosage, misuse, abuse (e.g. patient sharing products); * Medication errors (e.g. patient took wrong dose); * Lack of therapeutic efficacy (e.g. the product doesn't work); * Occupational exposure (e.g.: nurse administering the product is exposed); * Cases of suspected transmission of infectious agents; * Use of suspected or confirmed falsified product(s) or quality defect of the product(s); * Withdrawal reactions; * Accidental exposure (e.g.: child takes parent's product); * Drug-drug/drug-food interactions; * Unintentional use of product in a non-approved population (e.g.: pediatric or geriatric population); * Disease progression/exacerbation of existing disease
Number of off-Label Use14 days from the initiation of tolvaptan sodium phosphate treatmentCollecting any type of off-Label Use that refers to situations where a product is intentionally used for a medical purpose not in accordance with the authorized product information. Off-label use also includes the intentional use in nonauthorized population categories not indicated in the label.
Incidence of Serious Adverse Event (e.g. resulting in death or life-threatening)14 days from the initiation of tolvaptan sodium phosphate treatmentCollecting the number of any adverse drug experience/event occurring at any dose which * results in death * is life-threatening * requires inpatient hospitalization or prolonged of existing hospitalization * results in persistent or significant disability or incapacity * is a congenital anomaly/birth defect * is medically significant.
Incidence of Non-serious Adverse Events (i.e. all Adverse Events that do not meet the definition of a serious Adverse Event)14 days from the initiation of tolvaptan sodium phosphate treatmentCollecting the number of non-serious Adverse Events
