In order to figure out the FDA approval dates for Elagolix, Linzagolix, and Opigolix, we mainly relied on FDA databases like Access Data. There, no results came up for Linzagolix and Opigolix. Knowing that this might be an indication that the drugs have not been approved by the FDA, we turned to the official websites of the companies developing these drugs. We found that these companies provided no information on the FDA approval of their drugs. We then examined their press releases and annual reports. Through these mediums, we were able to conclude that they have not approved by the FDA. The same approach was carried out to find the dates of FDA submission and randomized clinical trials of the drugs. To get a breakdown of the randomized clinical trials (RCT) for Elagolix, Linzagolix, and Opigolix, we leveraged a clinical trial database managed by the US National Library of Medicine.
