Gilead Sciences Inc., whose Covid-19 treatment has whipsawed markets amid conflicting early reports about its efficacy, is set to report the first results from a company-sponsored study of the experimental drug.

Data from the first 400 severely ill coronavirus patients being treated with remdesivir in an open-label study are expected before the end of next week. While not expected to provide a definitive answer on efficacy, the report is likely to again trigger wide swings in Gilead’s shares and the broader market. Options prices show investors expect a more than 9% move in the drugmaker’s stock price over the next week.
