Our Team

The founding of ALX Oncology was based upon technology invented at Stanford University. This discovery involves soluble versions of signal regulatory protein-α (SIRPα) that have been engineered to bind CD47 with significantly greater affinity than natural SIRPα.1

ALX Oncology is an independent, private biotechnology company. Since May 2015, we have raised a total of $176 million in funding.
