Detailed Description
There is an increased lack of short- and long-term real-life effectiveness and safety data on new oral antivirals authorised and commercialised to treat COVID-19. To date, only two clinical trials have been published with data on the efficacy and safety of the use of the Paxlovid® and Lagevrio®. Since there is a public health, political, social and economic pressure to prevent severity, hospitalisation and death from COVID-19, monitoring the effectiveness and safety of commercialised oral antiviral therapies against COVID-19 has become emergent pharmacovigilance and public health task6.
A real-life cohort event monitoring system allows for the monitoring of newly introduced oral antivirals, in addition to existing spontaneous reporting systems and healthcare database studies (i.e., secondary data), as it is complementary to these systems in several ways. First, it is better suited to capture the more frequent AE, including those that are not medically attended. It generates more comprehensive safety data, e.g. on disease course and the impact of the AE. Moreover, there is insufficient data on these new medicines in real clinical practice, particularly from large-scale studies on the long-term efficacy or safety.
This work, with scientific and academic interest but, essentially, clinical and regulatory importance, constitutes a duty of the regional pharmacovigilance units. As such, it is also an obligation of the Pharmacy and Therapeutics Commissions, based on the legislation in force, to "collaborate in studies to monitor the safety and effectiveness of medicines promoted in the context of the National Pharmacovigilance System".

Description
Inclusion Criteria:
Participants eligible to be included in the study are identified by medical prescribing of one of the drugs under study, and either the medicine recipient or their proxy should:
- Comply with the eligibility criteria for prescribing these drugs (including patients ≥ 18 years old), according to Norm nr 005/2022 of the General Directorate of Health of Portugal*;
- Enrol in the study within the first 72 hours after dispensing treatment;
- Be able to understand the Portuguese language;
- Available for follow-up during study time;
Provide informed consent.
- Compliance with the eligibility criteria for prescribing these drugs is the sole responsibility of the prescriber who assesses the patient, so the study centres only include patients referred by the prescriber.
Exclusion Criteria:
Will be considered ineligible participants those who:
- Are not available for follow-up and monitoring;
- Participate in phase I, II, III or IV clinical trials;
- Life expectancy is less than one month.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Safety outcome
Time Frame: 6 days after onset treatment for both drugs.
|
The incidence of AE (with particular focus on AE of special interest) that emerge during or after the treatment period, serious AE, and AE leading to discontinuation of the treatment, as coded according to the MedDRA. Incidence data will be provided for each treatment group within the safety analysis population, including all patients who received at least one drug dose. The occurrence of AE will be asked in open question / unsolicited. For each reported AE, date of onset, outcome, duration of symptoms (if recovered), and severity/impact of the symptoms (including medical assistance & hospitalisation) will be asked. |
6 days after onset treatment for both drugs.
|
Safety outcome
Time Frame: 39 days after treatment onset for nirmatrelvir/ritonavir cohort.

Effectiveness outcome
Time Frame: 29 days after treatment onset for both drugs.
|
The incidence of hospitalisation for any cause (defined as ≥24 hours of acute care in a hospital or any similar facility) or death for any cause through day 29.
|
29 days after treatment onset for both drugs.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Adherence to treatment
Time Frame: 6 days after onset treatment for both drugs.
|
Will be measured using the self-reported 7-item Measure Treatment Adherence (MTA) tool validated for the Portuguese Population.
The MTA is a psychometric tool derived from the Morisky et al. questionnaire and evaluates the individuals' behaviour concerning the daily use of medication.
|
6 days after onset treatment for both drugs.
