ImmuPharma said it remains on track to provide top-line results in the first quarter of next year.
The data was provided ahead of an investor update to be held in London that will be coupled with the company’s annual meeting later Friday.
“As the trial continues to progress, we are delighted to observe the continuation of our robust safety record, as Lupuzor is being administered to greater numbers of patients over a longer period of time,” chairman Tim McCarthy said
