A Study for Patients With Head and Neck Cancer

OS duration is defined as the time from the date of randomization to the date of death from any cause. For each participant who is not known to have died as of the data-inclusion cut-off date, OS duration will be censored at the date of the participant's last contact prior to that cut-off date.

Objective PFS is defined as the time from date of randomization to date of objectively determined progressive disease (PD) or death from any cause, whichever comes first. PD was defined by Response Evaluation Criteria in Solid Tumors (RECIST). PD=at least a 20% increase in sum of longest diameter of target lesions. For participants who are not known to have died as of the data-inclusion cut-off date, and who do not have progressive disease, PFS will be censored at the date of the last objective progression-free disease assessment prior to the date of any subsequent systemic anticancer therapy.

Tumor Response is evaluated as CR (Complete Response) or PR (Partial Response) per Response Evaluation Criteria in Solid Tumors (RECIST criteria). Possible evaluations include: CR: Disappearance of all target lesions. PR: At least a 30% decrease in the size of target lesions. Response rate (%) = (number of participants with CR+PR/number of participants)*100

DoR is time from first observation of complete response (CR) or partial response (PR) to first observation of PD or death. Response is objective status of CR or PR using RECIST criteria. CR is disappearance of lesions. PR is >30% decrease in size of lesions. Responder is any participant with CR or PR. PD is at least 20% increase in sum of longest diameter of target lesions. For participants alive as of data-inclusion cut-off date and who do not have PD, DoR will be censored at date of last objective progression-free disease assessment before date of any subsequent systemic anticancer therapy.

FACT-H&N consists of 39 items with 5-point rating scale from 0 (not at all) to 4 (very much). FACT-H&N Total score ranges from 0 to 148. Higher score represents a better quality of life. Time to worsening was defined as the first date of worsening in the FACT H&N Total score that was considered at least the prospectively defined minimally important difference (MID) as compared with participant's baseline score, or date of death from any cause. The MID for FACT H&N Total score was a decrease of 12 points.

Correlation between highly up/downregulated genes and clinical response (Overall Survival (OS) and Progression-Free Survival (PFS)). OS is is defined as the time from the date of randomization to the date of death from any cause. PFS is defined as the time from the date of randomization to the date of objectively determined progressive disease or death from any cause, whichever comes first.

0 participants were analyzed; Reason: The relatively low number of samples collected would not have yielded a meaningful genomic analysis and the decision was made to not analyze the data.
