General information about the trial
|
|||
Main objective of the trial |
• To evaluate the efficacy, as measured by progression free survival (PFS), of MEHD7945A (administered every 2 weeks) versus cetuximab (administered weekly) in subjects with recurrent/metastatic squamous cell carcinoma of the head and neck (R/M SCCHN)
• To evaluate the efficacy, as measured by PFS, of MEHD7945A (administered every 2 weeks) versus cetuximab (administered weekly) in subjects with R/M SCCHN whose tumors express high levels of heregulin (HRG)

Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
24 Aug 2012 |
Study GO28076 had been amended primarily to address comments and recommendations received from study investigators regarding enrollment of patients who have failed platinum-based therapy and are not eligible for local focal therapy as well as reducing the wash-out period required for non-biologic therapies prior to initiating study treatment. Additional changes had been made to ensure enrollment of at least 80 HPV-negative patients and to align the duration of pregnancy prevention with the duration of safety follow-up. |
||
12 Feb 2013 |
Study GO28076 had been amended primarily to update clinical data from the Phase I study, DAF4873g, as of 25 November 2012, including results from QT analyses (see Section 1.2.2) and to add triplicate electrocardiogram (ECG) monitoring for patients treated with MEHD7945A in Arms A and Ax. |
||
Interruptions (globally) |

Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
Study terminated early by Sponsor in Sep. 2014 due to primary analysis indicating primary endpoint of PFS improvement with MEHD47945A over Cetuximab was not met. One subject remained on MEHD7945A at the investigator’s request until June 2015. |
