4126 Background: Molecular targeting of pathways that are deregulated in pancreatic cancer is a promising approach aimed at improving the dismal prognosis of APC pts. However, the clinical impact of novel “biological” drugs (ND) remains to be defined. Methods: All prospective phase III trials comparing single-agent Gemcitabine (G) with either a ND or a combination of ND and G (ND+G) were considered eligible. A pooled analysis was performed and event-based relative risk ratios (RR) with 95% CI were derived through both a fixed- and a random-effect model approach, exploring OS as the primary outcome and PFS and ORR as secondary outcomes. Heterogeneity between different trials was also taken into account. Results: Six trials involving 2361 pts were identified; ND tested included: FTI inhibitors (1 trial), MMP inhibitors (3 trials), EGFR inhibitors (1 trial), and anti-gastrin vaccine (1 trial). The analysis was conducted considering three different subgroups: 1) overall population (2361 patients, 6 trials), 2) ND+G vs G (1879 patients, 4 trials), and 3) ND vs G (482 patients, 2 trials). As shown in the table, no significant differences in either the primary outcome (OS) or the secondary outcome of PFS were observed in the overall population as well as in ND+G vs G trials, while a significant negative trend for ND was found in ND vs G trials with regard to both endpoints. Conversely the evaluation of the secondary endpoint of ORR significantly favored G in the overall population as well as in ND vs G trials, while a not significant negative trend for ND was observed in ND+G vs G trials. Conclusions: G remains the treatment of choice in APC pts. The ND tested, either alone or combined with G, do not seem to add any benefit over G. A better understanding of pancreatic cancer biology and further clinical evaluation of new agents and is needed to improve prognosis in APC pts.

4118 Background: Since the introduction of gemcitabine (G), attempts have been made to develop G-based combination regimens to improve the dismal outcome of APC pts. Results of randomized trials, however, have been conflicting and single-agent G presently remains the standard of care for such pts. Methods: All prospective phase III trials comparing single-agent G with G-based polychemotherapy regimens (poly-G) were considered eligible. A pooled analysis was performed and event-based relative risk ratios (RR) with 95% CI were derived through both a fixed- and a random-effect model approach, exploring OS as the primary outcome and PFS and ORR as secondary outcomes. Heterogeneity between different trials was also taken into account. Results: Twelve trials involving 3682 pts were identified. The analysis was conducted considering three different subgroups: 1) overall population (3682 patients, 12 trials), 2) platinum-containing poly-G (PG) vs G (768 pts, 5 trials), and 3) fluoropyrimidine-containing poly-G (FG) vs G (1640 pts, 4 trials). As shown in the table, no significant differences in the primary outcome (OS) were observed in any of the three groups analyzed. Conversely, a significant advantage for poly-G was evident with regard to both PFS and ORR in the overall population as well as in the PG vs G subgroup, although with some heterogeneity. A heterogeneous non-significant trend towards a better PFS and ORR outcome was also observed in the FG vs G subgroup. Conclusions: Single-agent G remains the treatment of choice in APC pts. However, the addition of platinum compounds to G appears to significantly improve PFS and ORR, possibly justifying the use of platinum-based poly-G in younger and fit patients.

e16723 Background: With the aim of improving the prognosis of the disease, in recent years attempts have been made to optimize the adjuvant treatment of pancreatic cancer, having demonstrated the usefulness of chemotherapy in several phase III trials: CONKO-001, JASPAC-01, ESPAC -4 and PRODIGE. Methods: The method to measure the Area Under the Curve (AUC) is universally known. When the curve is not homogeneous, the AUC is calculated using the traditional method of breaking down the total area into a sum of many polygons. We have calculated the AUC through pixel counting using Image J, which is an image processing application, programmed in Java, developed in the National Institutes of Health and free to access. To estimate the consistency between the pixels and the sum of polygons, we have performed several curves with linear edges to measure the AUC through the sums of the polygons, and then by counting pixels with the Image J application. We have verified that the results are similar, so the pixel count can be used to replace the sum of polygons, especially when the curves are not homogeneous. Entering the areas obtained with Image J in the worksheet, made for this purpose, and available for free at evalmed.es, the measures of the effect are automatically obtained: prolongation of the average surival time (PtS), prolongation of the average event free time (PtSLEv) and time lived without an event (PtvSEV). Results: The median follow-up in all studies was 60 months, with the exception of CONKO-001, for which we have data at an average follow-up time of 136 months, however for our comparative purpose we cite the results in the first 60 months. -CONKO-001: PtS was 5.1 months (24.2 observation vs 29.3 gemcitabine). PtSLEv was 9.6 months (13 observation vs 22.6 gemcitabine). PtvSEv was 22.57 months. -JASPAC-01: PtS was 9.04 months (32.4 gemcitabine vs 41.5 gemcitabine + S1). PtSLEv was 9.75 months (21.6 gemcitabine vs 31.4 gemcitabine + S1). PtvSEv was 31.38 months. -ESPAC-4: PtS was 3.2 months (34 gemcitabine vs 37.2 gemcitabine + capecitabine). PtSLEv was 2.7 months (25.6 gemcitabine + 28.3 gemcitabine + capecitabine). PtvSEv was 24.92 months. -PRODIGE: PtS was 6 months (37 gemcitabine vs 43 FOLFIRINOX). PtSLEv was 8.9 months (22.4 gemcitabine vs 31.2 FOLFIRINOX). PtvSEv was 31.23 months. Conclusions: In the adjuvant treatment with chemotherapy in pancreatic cancer, the transit from observation to gemcitabine, and from here to the most intensive schedules, has meant or contributed an important advance for patients in terms of PtS, PtSLEv and PtvSEv.

The design and conduct of a randomized, double-blinded, placebo-controlled, multicenter, phase III study of recombinant interferon beta-1a (IFN-β-1a) as treatment for exacerbating-remitting MS are described, as are baseline characteristics of the study population. The purpose of the study was to determine if 6.0 × 106 IU (30 μg) of IFN-β-1a, administered by weekly intramuscular (i.m.) injections, was effective in delaying the onset of sustained disability. The primary outcome measure was time to onset of treatment failure, defined as a worsening on the Kurtzke Expanded Disability Status Scale (EDSS) of greater than or equal to 1.0 point compared with baseline, persisting for at least 6 months. An intent-to-treat design was used. The primary outcome measure was analyzed using the Mantel-Cox log-rank statistic and Kaplan-Meier survival curves. Secondary outcomes included quantitative measures of upper and lower extremity function, neuropsychological test performance, functional and quality of life assessments and several measures derived from annual brain MRI studies. Entry criteria included prestudy exacerbation rates of at least 0.67 per year and EDSS scores of 1.0–3.5. A total of 301 MS patients were randomly assigned to receive weekly i.m. injections of IFN-β-1a or placebo. The average age of the study population at entry was 37 years; 92% were Caucasian and 73% were women. The mean prestudy disease duration was 6.5 years, mean prestudy exacerbation rate was 1.2 per year and the mean EDSS score was 2.3. The randomization yielded well-balanced treatment arms. Various aspects of the study are discussed, including: (1) the decision to focus study design on sustained disability; (2) the rationale for the treatment regimen; (3) measures taken to assure the reliability of the primary outcome measure; and (4) a description of the secondary outcome measures.
