Secondary | Duration of Response | Duration of responses based on assessment of confirmed complete response (CR) or confirmed partial response (PR) according to RECIST. Confirmed CR defined as disappearance of all target lesions. Confirmed PR defined as =30% decrease in sum of the longest dimensions (LD) of the target lesions taking as a reference the baseline sum LD according to RECIST. Confirmed responses are those that persist on repeat imaging study =4 weeks after initial documentation of response. | Every 2 cycles (each cycle=21 days) until disease progression or participant discontinuation; maximum follow-up was from baseline up to 12 cycles | No |
Secondary | Germ Line Polymorphism of Candidate Genes Targeted by PF-03814735 | Percentage of germ line polymorphism cell expression in relation to clinical response. Responses include CR: disappearance of all target lesions; PR: =30% decrease in sum of LD of target lesions referencing baseline sum LD; Progressive disease: =20% increase in sum LD of target lesions from smallest sum LD recorded since Tx start or appearance of =1 new lesions; Stable disease: neither sufficient shrinkage to=PR nor sufficient increase to=PD during first 6 weeks after Tx start referencing smallest sum LD since Tx start. | Schedule A Cycle 1 or Cycle 2 /Day 4 or Day 5, Schedule B Cycle 1/Day 9 or Day 10 (each cycle=21 days) | No |
Secondary | Aurora Gene Somatic Mutations/Amplification and Pathway Genes in Tumor Tissue | Percentage of aurora gene somatic mutations/amplification and pathway genes in relation to clinical response. Responses include CR: disappearance of all target lesions; PR: =30% decrease in sum of longest dimensions (LD) of target lesions referencing baseline sum LD; Progressive disease: =20% increase in sum LD of target lesions from smallest sum LD recorded since Tx start or appearance of =1 new lesions; Stable disease: neither sufficient shrinkage to=PR nor sufficient increase to=PD during first 6 weeks after Tx start referencing smallest sum LD since Tx start. | Schedule A Cycle 1 or Cycle 2 /Day 4 or Day 5, Schedule B Cycle 1/Day 9 or Day 10 (each cycle=21 days) | No |
