STAT News: New Covid trial results may point toward better ways to study medicines. “Last week, a clinical trial called TOGETHER produced two potentially important conclusions: A little-discussed experimental drug called peginterferon lambda cut in half the number of Covid-19 patients who ended up going to the emergency room or hospital. And the much-discussed antiparasitic drug ivermectin failed to prevent hospitalization for Covid patients at all. TOGETHER, like the RECOVERY study conducted in the United Kingdom and REMAP-CAP, conducted basically everywhere but the United States, was a platform study, a streamlined clinical trial that evaluated multiple medicines at once and that use a common placebo group. It’s from these platform studies that doctors have learned perhaps the most about Covid-19.”
