CADTH is committed to supporting Canada’s health care decision-makers through this challenging and uncertain time.
Our COVID-19 evidence portal contains the latest COVID-19 information from CADTH and other respected organizations. Content is updated daily to reflect the rapidly changing and growing state of the international scientific evidence related to this disease.
The following is a summary of the most recent information posted to our COVID-19 portal.
Webinar: Blood Plasma Therapies For COVID-19 (August 25, 2020)
- In this webinar, an expert panel will talk about convalescent plasma therapy and other plasma-based therapies being investigated in trials as potential treatments for COVID-19. The CONCOR-1 study, a nationwide clinical trial approved by Health Canada, will also be part of this discussion.
- Our panel of experts includes Dr. Dana Devine (Canadian Blood Services), Dr. Jeannie Callum (Sunnybrook Health Sciences Centre), and Heather Logan (CADTH).
- To participate, please register (there is no cost).
- CADTH searched the evidence-based guidelines on resuming routine cancer screening during the COVID-19 pandemic.
- One evidence-based guideline from the American Gastroenterological Association Institute was identified; however, no evidence-based guidelines that were either broader in scope, or specific to other fields, were identified.
- This tool provides general information about the drug dexamethasone and its past uses, as well as new evidence for dexamethasone as a potential treatment for COVID-19.
- The results from the dexamethasone arm of the RECOVERY trial are provided, together with the current Canadian recommendations for its use in treating those with COVID-19.
- The HIV medications lopinavir and ritonavir (LPVR), in combination, are currently being investigated as a proposed COVID-19 treatment.
- The potential mechanism of action of LPVR is that it may disrupt the replication and spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) within the body.
- However, there is uncertainty around the clinical effectiveness of LPVR in patients with COVID-19.
- CADTH reviewed and summarized the evidence regarding the clinical effectiveness of LPVR for the treatment and prevention of COVID-19.
- Favipiravir is an oral antiviral drug that has emerged as a potential treatment or prevention option for COVID-19.
- An international expert panel issued a weak recommendation for not using favipiravir in patients with non-severe or severe COVID-19 because of low-quality evidence.
- Favipiravir is not approved in Canada and is not currently accessible outside of clinical trials.
- The horizon scan that evaluated the efficacy and safety of favipiravir for the treatment of COVID-19 identified two published studies related to the drug.
- This report reviews the current scientific evidence on the potential benefits and harms of chloroquine and hydroxychloroquine for the prevention or treatment of COVID-19.
- A total of four trials were identified — three treatment trials and one prevention trial.
- The evidence available at this time is limited in both quantity and quality, with some of the studies terminated early due to safety concerns.
- CADTH will continue to update this report as more evidence becomes available.
- CADTH conducted a limited literature search to identify a list of potential technologies that may be used to address the negative effects of social isolation on older adults living in long-term care.
- A list of technologies that encourage engagement and communication is identified; these include technologies for robotic companions and pets, physical activities and games, and communication.
- Where possible, the availability of the technology in Canada is noted.
