Hide Outcome Measure 4

Measure Type	Secondary
Measure Title	Percentage of Participants With Disease Control (CR, PR, or SD)
Measure Description	This is the total number of patients with a best overall response of CR, PR, and stable disease (SD) divided by the total number of patients treated.
Time Frame	Tumor evaluations were performed at a minimum of every 6 weeks while on cetuximab therapy. Patients with a PR or CR had a confirmatory tumor assessment no less than 4 weeks after the initial evaluation demonstrating a response.
Safety Issue	No

Population Description

Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Disease control rate was the total number of patients with best overall response of CR, PR and SD divided by the total number of patients treated.

The sponsor cannot require changes to the communication and cannot extend the embargo.
	The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
	Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed. Restriction Description: Investigators may not independently publish/disclose any study data, findings or conclusions except as part of an overall multi-center publication. After final publication, or if a draft publication is not produced within approximately 6 months of the final report of the study results, investigators may independently publish, subject to review for sponsor confidential information which may be redacted at sponsor request. Publication may be delayed up to 90 days to seek patent protection.
