PRIMARY outcome

Timeframe: From time of first dose of study drug through 6 months

Population: Treated participants; all participants who received at least one dose of ixabepilone or cetuximab. Participants who did not die prior to 6 months but dropped out of the study were not included in the numerator.

The percentage of participants surviving at 6 months was defined as the number of treated participants who had not died prior to 6 months from the date of their first dose divided by the total number of treated participants.

SECONDARY outcome

Timeframe: From time of first dose of study until 16.49 months (longest period for participant between first dose and documented disease progression)

Population: Response-evaluable participants; all participants with measurable disease who received at least one dose of ixabepilone or cetuximab and who had at least one on-treatment tumor assessment.

Tumor response was assessed according to the Response Evaluation Criteria In Solid Tumors (RECIST) criteria: Complete Response (CR)= disappearance of all non-target lesions, Partial Response (PR)= at least 30% reduction in the sum of the longest diameter (LD) of all target lesions in reference to the baseline sum LD; Stable Disease (SD)= neither PR nor progressive disease (PD) criteria were met; PD = at least 20% increase in the sum of the LD of all target lesions, taking as reference the smallest sum LD recorded at or following baseline.

Population: Response-evaluable participants; all participants with measurable disease who received at least one dose of ixabepilone or cetuximab and who had at least one on-treatment tumor assessment.

Percentage of participants with objective tumor response was determined by the number of participants with PR or CR divided by the total number of response-evaluable participants. Tumor response was assessed according RECIST criteria: PR=at least 30% reduction in the sum of the LD of all target lesions in reference to the baseline sum LD, CR=Disappearance of all non-target lesions.

SECONDARY outcome

Timeframe: From the first dosing date of Cycle 1 until the last dosing date of the last cycle. Last dosing cycle for a participant was Cycle 21.

Population: Since the combination of ixabepilone and cetuximab tested in this trial failed to meet the primary objective of sufficiently improving 6-month survival rate relative to historical control in participants with metastatic pancreatic cancer, dose modification data were collected but not summarized.

Dose reduction of ixabepilone and/or cetuximab due to toxicity was permitted for participants deriving benefit from therapy. Each drug could be dose modified independently of the others. Participants unable to start a cycle due to unacceptable toxicity related to ixabepilone or cetuximab could have therapy delayed for up to 4 weeks. If toxicities prevented the administration of ixabepilone or cetuximab therapy, participants continued receiving the other therapy as scheduled. A dose interruption for ixabepilone or cetuximab was defined as any interruption during the infusion period.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Baseline

Population: Tissue was available for a small proportion of patients and only 1 out of 11 was EGFR positive, hence EFGR expression analysis was not performed.

EGFR expression was evaluated by means of an immunohistochemical assay using tumor tissue collected prior to receiving first dose.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Baseline, Week 3, Week 6, Week 9, Week 12, Week 12, Week 18, Week 24 and every 3 weeks through end of study (participant death/withdrawal from study)

Population: Since the combination of ixabepilone and cetuximab tested in this trial failed to meet the primary objective of sufficiently improving 6-month survival rate relative to historical control in participants with metastatic pancreatic cancer, FHSI-8 score data were collected but not summarized.

The FHSI-8 includes eight items representing pancreatic-related symptoms; each symptom is rated by participants on a scale of from 0 to 4. The FHSI-8 total score ranges in value from 0 to 32, with higher scores representing fewer symptoms and lower scores representing more symptoms. Scoring of the FHSI-8 was to be conducted according to the Functional Assessment of Chronic Illness Therapy (FACIT) manual. The symptom assessment was to include treated participants who had baseline measurement and at least one on-study measurement of FHSI-8 questionnaire.

n=54 participants at risk
All participants were administered ixabepilone at a starting dose of 32 mg/m\^2 as a 3-hour intravenous (IV) infusion every 3 weeks. In addition, all participants were administered an initial dose of cetuximab (400 mg/m\^2 IV over 2 hours) followed by a weekly lower dose (250 mg/m\^2 IV over 1 hour).
