GSK Biologicals' 2241658A Antigen-Specific Cancer Immunotherapeutic

Severe toxicity was defined, according to the Common Terminology Criteria for Adverse Events (CTCAE) (version 4.0), as 1)an Antigen-Specific Cancer Immunotherapeutic (ASCI) related or possibly related Grade 3 or higher toxicity. Grade 3 myalgia, arthralgia, headache, fever, rigors/chills and fatigue (including lethargy, malaise and asthenia) should persist for 48 hours despite therapy to be taken into account and as 2)an ASCI related or possibly related Grade 2 or higher allergic reaction occurring within 24 hours of the dose administration.

Grade 3 myalgia, arthralgia, headache, fever, rigors/chills and fatigue (including lethargy, malaise and asthenia) should persist for 48 hours despite therapy in order to be taken into account and as 2)an ASCI related or possibly related Grade 2 or higher allergic reaction occurring within 24 hours of the dose administration. All active follow-up visits and procedures were stopped, hence this follow-up analysis was not performed as initially planned.

Best response was recorded from the start of treatment until disease progression. Response assessment was essentially based on a set of measurable lesions (target lesions \[TL\]), and any other lesions (non-target lesions \[NTL\]), both identified at baseline. Complete Response (CR)=disappearance of all TL or NTL; Partial Response (PR) = at least 30 percent (%) decrease in the sum of the longest diameter(LD) of TL compared to baseline, stable disease (SD) = neither sufficient shrinkage to qualify PR nor sufficient increase to qualify for Progressive disease (PD) compared with baseline; PD = at least 20% increase in the sum of LD of TL compared with baseline, or the appearance of one or more new lesions, or both of these, and/or unequivocal progression of existing NTL; NE =non-evaluable; Clinical response: any CR or PR best overall response; Disease control: any CR, PR, SD or SD/PR best overall response.
