Is anyone else in the ALTA3263 clinical trial for colon cancer?

My husband started ALTA 3263 about 3 weeks ago for stage 4 colon cancer (current liver lesions). He gets his third cetuximab infusion soon and takes 400 mg pills twice per day. His first scan for this treatment is in about 3 weeks. He has symptoms that are sometimes unpleasant, but nothing unmanageable so far. I'm hoping and praying this works for CRC patients.
