HGEN is blinded still, they are just doing some reverse engineering of the numbers based on the recommended increase in patients by the DSMC.

From the PR (this was Nov 6th, so I'm not sure you can contribute any spikes today related to a PR from 2 weeks ago)...any bold emphasis is mine.

The data safety monitoring board (DSMB) composed of independent subject matter experts conducted an interim analysis of the unblinded data for trial sizing and powering and recommended increasing the target number of events (recoveries) from 257 to 402 to maintain the power of the study at 90 percent. The adaptive trial design only allows for the addition of patients if interim data are in the “promising zone” (i.e., achieving or surpassing an average improvement in recoveries of 29 percent (hazard ratio (HR) > 1.29) through day 28).

The company remains blinded to the data and based on the recommended number of events, the HR was calculated to be 1.37, an average of 37 percent more recoveries observed in the lenzilumab arm compared to the control arm. Any observed benefit in the lenzilumab arm would be over and above the use of remdesivir and/or steroids which are among the treatments that have been used as SOC in both the lenzilumab treatment arm and the placebo arm of the study.

At the recommendation of the DSMB, the company plans to increase enrollment to achieve 402 events (approximately 515 patients). This increase in enrollment ensures an even higher probability of success in meeting the primary endpoint and maintains the power of the study at 90 percent.
