ImmunityBio Founder Issues Clarification

However, Patrick Soon Shiong, ImmunityBio’s founder, took to X on Saturday to clarify what the update signified.

“The fact that we have patients alive still at 12 months and that the ‘median has NOT YET  been reached’ IS a positive and promising finding to date with our chemo free treatment in which patients have failed current standards of care,” he said.

He added that “median overall survival” is a scientific endpoint that is used to measure survival, which currently stands at six months for patients with brain tumors. Explaining what this means, he said that half of the patients at this stage do not survive beyond the timeframe of six months or longer.
