Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety of Gedatolisb + PTK7-ADC using NCI CTCAE v4.0	safety and toxicity data will be assessed using NCI CTCAE v4.0 and tabulated and reported	through study completion i.e. up to 1 year
Secondary	Efficacy in all enrolled subjects	efficacy as determined by clinical benefit at 18 weeks	18 weeks
Secondary	Overall response rate in all enrolled subjects	efficacy as determined by overall response rate	through study completion i.e. up to 1 year
Secondary	Progression free survival in all enrolled subjects	efficacy as determined by progression free survival	through study completion i.e. up to 1 year
Secondary	Pharmacodynamic determination of inhibition of PI3k signaling	Pathological H-score will be determined from tissue obtained at screening and Cycle 1 Day 15. H-score will be compared to calculate percentage inhibition between samples.	Cycle 1 Day 15
Secondary	Pharmacodynamic determination modulation of Wnt pathway	pathological H-score will be determined from tissue obtained at screening and Cycle 1 Day 15. H-score will be compared to calculate percentage change in expression between samples.	Cycle 1 Day 15
Secondary	Pharmacodynamic determination modulation of Wnt pathway	RNA sequencing of tissue collected at screening and Cycle 1 Day 1 to compare Wnt pathway expression after treatment	Cycle 1 Day 15
