Abstract: Palbociclib is a cyclin-dependent kinase 4 and 6 inhibitor approved for advanced breast cancer. In the adjuvant setting, the potential value of adding palbociclib to endocrine therapy for hormone receptor–positive breast cancer has not been confirmed. PATIENTS AND METHODS In the prospective, randomized, phase III PALLAS trial, patients with hormone receptor–positive, human epidermal growth factor receptor 2–negative early breast cancer were randomly assigned to receive 2 years of palbociclib (125 mg orally once daily, days 1-21 of a 28-day cycle) with adjuvant endocrine therapy or adjuvant endocrine therapy alone (for at least 5 years). The primary end point of the study was invasive disease-free survival (iDFS); secondary end points were invasive breast cancer–free survival, distant recurrence-free survival, locoregional cancer-free survival, and overall survival. RESULTS Among 5,796 patients enrolled at 406 centers in 21 countries worldwide over 3 years, 5,761 were included in the intention-to-treat population. At the final protocol-defined analysis, at a median follow-up of 31 months, iDFS events occurred in 253 of 2,884 (8.8%) patients who received palbociclib plus endocrine therapy and in 263 of 2,877 (9.1%) patients who received endocrine therapy alone, with similar results between the two treatment groups (iDFS at 4 years: 84.2% v 84.5%; hazard ratio, 0.96; CI, 0.81 to 1.14; P = .65). No significant differences were observed for secondary time-to-event end points, and subgroup analyses did not show any differences by subgroup. There were no new safety signals for palbociclib in this trial. CONCLUSION At this final analysis of the PALLAS trial, the addition of adjuvant palbociclib to standard endocrine therapy did not improve outcomes over endocrine therapy alone in patients with early hormone receptor–positive breast cancer.

Abstract: Background: As the development and use of oral anticancer agents increases, it is critical to understand patient adherence to both standard and investigational agents. The open label, phase 3 multicenter PALLAS trial investigates whether adding 2 years of the CDK4/6 inhibitor palbociclib (P) to adjuvant endocrine therapy (ET) improves invasive disease-free survival (iDFS) over adjuvant ET alone in patients (pts) with HR- positive, HR2-negative, stage II-III breast cancer. Pts were randomly assigned to either Palbociclib (125 mg/day, 3 weeks on, 1 week off, in a 28-day cycle) plus ongoing provider/patient-choice adjuvant ET (P+ET) versus ET alone. We examined patient-reported adherence to ET +/- P during the first two years of study treatment. Methods: Adherence outcomes were measured in English-speaking pts in the U.S., UK, Ireland and Australia, Spanish-speaking pts in Spain and Mexico, and German-speaking pts in Germany and Austria. Adherence measures included drug diaries completed at each cycle, pill counts (for P only) collected at each study visit, and the Morisky Medication Adherence Scale-4 item and the McHorney Adherence Estimator questionnaires completed at cycles 2, 3, 6, 12, 18, and 24 (22 months). Mean adherence for each cycle was defined as the average proportion of prescribed pills taken (via drug diary) across all patients who initiated that cycle. Persistence was defined as the duration of drug initiation to treatment cessation (via drug diary). Generalized estimating equations were used to model the “most adherent” pts on the Morisky (score = 5 vs score & lt;5) and “low risk” for adherence problems on the McHorney (score=0 vs score & gt;0) to compare the average difference between arms over time for ET, adjusting for baseline demographic and clinical variables. Results: 81% (N=4688) of PALLAS pts were included in this analysis. Median persistence to ET was 23.6 months in P + ET (n=2169), 23.7 months in ET alone (2136) and 20.4 months for P (n=2194). The number of pts who initiated each cycle for ET declined over time and was similar between arms; the decline was more marked for P (Table 1). Mean adherence range as measured by drug diary was 98.2-99.3% for ET in P+ET and 98.0 - 99.4% in ET alone; and for P, ranged from 93.4 - 98.8%. The adherence and persistence results were nearly identical whether measured by drug diary or pill count for P. The observed percent “most adherent” for P measured by the Morisky scale ranged from 71.9% - 79.6% and the percent “low risk” for adherence problems measured by the McHorney scale, 64.0% - 73.4%. The percent of pts “most adherent” and “low risk” for adherence problems to ET was higher, on average over time, in the P+ET group compared to ET alone (75% vs 68%, p & lt;0.01; 75% vs 72%, p=.05, respectively). Conclusions: Self-reported mean adherence for both P + ET and ET alone was strikingly high for pts who remained on therapy; persistence was also high with ET during the 2-year treatment period. Current analyses suggest that nonadherence to either P or ET was likely not a major contributor to the iDFS results seen in the overall PALLAS trial. These results illustrate the importance of measuring and monitoring patient adherence to oral study agents.

Abstract: Background Advances in the multidisciplinary care of hormone-receptor positive (HR+) early breast cancer (eBC) have markedly improved clinical outcomes: however, disease recurrence may still occur, particularly in patients (pts) with moderate or high-risk cancers at the time of diagnosis. The use of CDK4/6 inhibitors (CDK4/6i) combined with endocrine therapy (ET) is a standard of care for advanced breast cancer, supporting the rationale to study CDK4/6i in the eBC setting. Here we present the final protocol-planned analyses of the global phase III PALLAS trial investigating whether the addition of the CDK4/6i palbociclib (P) to adjuvant ET improves outcomes over ET alone for HR+/HER2- eBC. Methods PALLAS (PALbociclib CoLlaborative Adjuvant Study, NCT02513394) is a randomized phase III open-label trial in which pts with stage II-III HR+/HER2- eBC were randomized to receive either 2 years of P with adjuvant ET (P+ET) or ET alone. The primary endpoint is invasive disease-free survival (iDFS); secondary endpoints include distant recurrence-free survival (DRFS), locoregional recurrence-free survival (LRRFS), overall survival (OS), and safety. Mandatory biospecimen collection has supported the creation of an expansive translational science program, and long-term follow-up is planned. Revised sample size calculations required recruitment of 5600 pts in order to detect a 25% iDFS improvement in patients receiving P+ET with 85% power; this final protocol-planned analysis was planned after 469 iDFS events. Results From September 1, 2015 to November 30, 2018, 5,761 pts (median age 52 years, range 22-90) were randomized in 406 centers in 21 countries worldwide. 1,014 (17.6%) had stage IIA disease (capped) and 4,728 (82.1%) stages IIB/III. 4,754 (82.5%) had received prior (neo)adjuvant chemotherapy. After a protocol-planned 2nd interim analysis in May 2020 crossed the futility threshold, 349 P+ET pts still on active treatment stopped P and were transferred to follow-up. At the time of final analysis cutoff date (November 20, 2020), after a median follow-up of 31 months and 516 events recorded, iDFS was similar between the two arms, with 3-year iDFS of 89.3% (95% CI: 87.8-90.6%) for Palbo+ET, and 89.4% (88.0-90.7%) for ET alone (hazard ratio 0.96, 95% CI: 0.81-1.14). There was no statistically significant difference in secondary outcome endpoints. Subgroup analyses revealed no significant interactions between treatment effect and other factors (including risk category). The safety profile of P was as expected, with grade 3 or 4 neutropenia the most common side effect (safety population: 1759/2841 [61.9%] vs 11/2902 [0.4%] ). Overall 42% of pts. discontinued P prior to the planned 2-year duration, 28.2% of Palbo+ET pts discontinued therapy due to adverse events, without an observed impact on survival outcomes. Conclusions Now with the full number of events, this analysis of the PALLAS trial shows that the addition of 2 years of P to ongoing adjuvant ET did not improve survival endpoints for pts with stage II-III HR+/HER2- eBC. Whether P is beneficial in the adjuvant setting for certain sub-groups of pts will be further evaluated with longer-term follow-up and by the ongoing translational science program.

Abstract: Translational research and the clinical development of therapeutic cancer vaccines require strong scientific rationale in order to better understand the mode-of-action and to incorporate the lessons learned in the optimization of cancer vaccines by (i) selecting appropriate immunomodulators to generate more effective vaccine regimens, (ii) combining vaccine regimens and standard-of-care therapeutics with synergistic potential and (iii) identifying patient populations that may have a better chance of responding to the vaccine. Here we demonstrate how preclinical and clinical immune response markers combined with cellular and serum biomarkers that define the immune regulatory environment were utilized as guiding tools in the development of three novel multi-peptide vaccines in renal cell cancer (IMA901), colorectal cancer (IMA910) and glioblastoma (IMA950). All three vaccine products comprise multiple tumor-associated peptides (TUMAPs) confirmed, by mass spectrometry, to be naturally presented in human cancer tissue. Each vaccine was selected using differential transcriptomics approaches and validated by in vitro analysis of immunogenicity with artificial antigen-presenting cells followed by in vivo analysis of immune responses in clinical trials. The vaccines contain HLA class I and II-restricted peptides designed to elicit CD8+ cytotoxic and CD4+ helper T-cell responses, respectively. IMA901 is a novel renal cell cancer (RCC) vaccine consisting of 9 HLA class I and 1 HLA class II TUMAPs with the majority of peptides confirmed to be naturally presented on and shared between RCC tissues. Consecutive independent Phase I and II clinical studies were conducted in HLA-A*02+ advanced/metastatic RCC patients (total 96) receiving repeated intradermal vaccinations with IMA901 plus human granulocyte-macrophage colony-stimulating factor (GM-CSF). The two studies demonstrated an association between overall survival and multiple vaccine-induced T-cell responses and an impact of single-dose cyclophosphamide (300 mg/m2) on regulatory T cells (Tregs) and overall survival. Furthermore, two myeloid-derived suppressor cell (MDSC) populations (CD14+ HLA-DR−/low and CD14− CD11b+ CD15+) were significantly negatively associated with survival in vaccinated RCC patients. The knowledge acquired in these trials was used to design a randomized, controlled Phase III study. Recruitment of 339 advanced/metastatic first-line RCC patients was recently completed. IMA901 is combined with the tyrosine kinase inhibitor sunitinib based on the findings that sunitinib down-modulates the two MDSC populations described above. Furthermore, in this Phase III study, the relevance of two serum biomarkers (Apoliprotein A1 and CCL17) found in the Phase II study to be associated with immune response and OS will be prospectively explored (Walter, Weinschenk et al., Nat Med 2012). IMA910 is a novel colorectal cancer (CRC) vaccine consisting of 10 HLA class I and 3 HLA class II TUMAPs with the majority of peptides confirmed to be naturally presented on and shared between CRC tissues. A Phase I/II trial was conducted in 92 HLA-A*02+ advanced colorectal cancer patients with stable (SD) or responding (PR/CR) disease after 12 weeks of first-line oxaliplatin-based therapy. Thereafter, first-line oxaliplatin-based chemotherapy was stopped and patients received a single dose of cyclophosphamide to reduce Tregs followed by repeated intradermal vaccinations with IMA910 plus GM-CSF (first cohort; n=66) with or without topically applied imiquimod (second cohort; n=26). IMA910 elicited immune responses towards multiple class I (in 43% of the subjects) and class II TUMAPs (65%). Similarly to the IMA901 vaccine trial in RCC, such vaccine-induced CD8+ as well as CD4+ T-cell responses to multiple TUMAPs were associated with increased overall survival. Patients who additionally received imiquimod were more often multi-peptide class I responders (p=0.016) as determined by intracellular cytokine staining (ICS) assay and showed a modestly (two-fold) increase of T-cell freqencies (p=0.12) as determined by HLA multimer assay. Interestingly, the same two populations of MDSC as described above in renal cell cancer patients were negatively associated with vaccine-induced immune response and overall survival implying a potential generalized role of these two MDSC populations. Further development of this vaccine is planned in a setting where an MDSC-modulating standard-of-care (e.g. chemotherapy) is applied. IMA950 is a novel glioblastoma vaccine consisting of 9 HLA class I and 2 HLA class II TUMAPs with the majority of peptides confirmed to be naturally presented on and shared between glioblastoma tissues. A Phase I study sponsored by Cancer Research UK is currently ongoing in the United Kingdom. A total of 45 newly diagnosed glioblastoma patients will be treated. The study is expected to complete recruitment in the first quarter of 2013. The primary objectives of this first-in-man study are to assess the safety, tolerability and immunogenicity of IMA950 plus GM-CSF when given alongside standard chemoradiotherapy followed by adjuvant chemotherapy with temozolomide. Patients enter the trial into one of two cohorts (start of vaccination either prior to or after initial chemoradiotherapy) in order to determine potential differences in the immune response in these two cohorts. First immunomonitoring data indicate a high immune as well as multi-TUMAP response rate in the study population. Updated and unpublished immune data will be presented at the meeting. Analysis of the in vitro immunogenicity data obtained from healthy donors during the discovery phases of these programs and comparison of these data with the in vivo immunogenicity data obtained in the clinical trials demonstrated that in all four clinical trials in a total of approx. 200 patients the in vitro data correlated with the in vivo data. This implies that such a standardized in vitro assay system may be utilized in future to further optimize vaccine regimens by selecting the most immunogenic novel peptides before entering clinical trials. In conclusion, we suggest that use of preclinically well characterized naturally presented tumor antigens combined with systematic clinical immunomonitoring and cellular/serum biomarker screening will be helpful to guide rational development of novel cancer vaccines.

Abstract: Abstract 535 Introduction: In 2008, first results of a multicenter, international randomized phase III trial (CLL8) were presented, showing superiority of FCR chemoimmunotherapy for response rates and progression-free survival (PFS) when compared to FC chemotherapy. We now report updated results with a longer median observation time of 37.7 months (mo). Methods and Patients: 817 treatment-naïve patients (pts) with good physical fitness and CD20-positive CLL randomly (1:1) received treatment with 6 courses of either FCR or FC therapy. Both treatment arms were well balanced with regard to sex, age, stage, genomic aberrations and IGVH gene status. The median age was 61 years (range 30 to 81), 25.7% pts were female in both arms, 64.1% were Binet B, 31% Binet C and 4.9% Binet A. The median cumulative illness rating scale (CIRS) score was 1 (range 0-8). The overall incidences of trisomy 12 and abnormalities of 13q, 11q23, and 17p13 detected by FISH were 12%, 57%, 25%, and 8%, respectively. A mean number of 5.2 treatment courses were delivered in the FCR arm vs 4.8 courses in the FC arm (p=0.006). Dose reductions by more than 10% in at least one treatment course were performed in 47% (FCR) and 27% (FC) of pts (p 〈 0.001), respectively. 74% (FCR) and 67% (FC) of pts received 6 cycles (p=0.02). The total median cumulative dose applied per pt was 775 mg for F and 7712 mg for C, with no statistically significant difference among the two treatment arms. Pts in Binet stages A and B received more treatment cycles (5.31) than Binet C pts (4.52; p 〈 0.001). Only 57.1% (FC) and 60.3% (FCR) Binet C pts received 6 cycles. Dose reductions by more than 10% were observed in 49% of FCR pts (vs 28% FC (p=0.001). Results: As of June 2009, the median observation time was 37.7 (mo). 761 pts (FCR 388; FC 371) were evaluable for response, 790 pts (FCR 401; FC 389) for PFS and all for OS. FCR induced a higher overall response rate than FC (95.1 vs 88.4%) and more complete remissions (44.1 vs 21.8%; p 〈 0.001). Median PFS was 32.8 mo for FC and 51.8 mo for FCR pts (p 〈 0.001, Hazard Ratio (HR) 0.56, CI 95% 0.460-0.689). The largest benefit for FCR was observed in Binet stage A and B for CR, ORR and PFS (Binet A: p=0.08, HR 0.423 CI 95%, 0.157-1.135, Binet B: p 〈 0.001 HR: 0.504 CI 95%, 0.390-0.651, Binet C: p=0.08, HR 0.732 CI 95%, 0.514-1.041). In Binet C, the median PFS was 14 mo for pts treated with up to 3 courses FC, but 44 mo for pts that received 4 courses or more (p 〈 0.001). Median PFS for pts treated with up to 3 cycles FCR was 12.5 mo, while for pts with 4 cycles or more, median PFS has not been reached (p 〈 0.001). Statistically significant differences were observed in OS between the two treatment arms. The OS rate at 37.7 mo was 84.1% in the FCR arm versus 79.0 % in the FC arm (p=0.01). In both arms, the median OS has not been reached. Only patients in Binet stages A and B showed a superior OS after FCR treatment (Binet A: HR 0.19, CI 95%, 0.023-1.613 p=0.09; Binet B: HR 0.45, CI 95%, 0.296-0.689, p 〈 0.001; Binet C HR1.4, CI 95%, 0.843-2.620, p=0.168). As previously reported more hematologic adverse events, particularly neutropenia, were observed with FCR treatment, but this did not result in an increased infection rate. More deaths have occurred in the FC arm (86/396, 21.7%) than in the FCR arm (65/404, 16.1%). In the majority of cases, the underlying cause of death was progressive disease (FC 48/86, FCR 33/65), secondary malignancies (FC 13/86, FCR 5/65) or unrelated causes of death such as myocardial infarction (FC 15/86, FCR 17/65). Treatment related mortality occurred in 8 (2.0%) of pts in each arm. Of these, 7 FC-treated pts and 5 FCR-treated pts died from infections related to treatment. In 7 pts (3 FC vs. 4 FCR), treatment was discontinued before the third treatment course due to fatal toxicity. Multivariate analysis was performed to evaluate factors predicting outcome. Age, sex, FCR-treatment, response, number of cycles (0-3), 17p-deletion, increased serum levels of thymidine kinase and β2-microglobulin and unmutated IGVH genes were independent prognostic factors predicting OS or PFS. Conclusion: Treatment with FCR chemoimmunotherapy is more effective than FC chemotherapy. The partial failure to demonstrate a benefit for FCR in Binet stage C patients may be related to an insufficient treatment intensity in these patients with higher tumor load. To our knowledge, this is the first time that a randomized trial is able to demonstrate that a specific first-line treatment for CLL results in an improved overall survival. The results corroborate the recommendation to use FCR as standard therapy in physically fit pts with CLL requiring therapy. Disclosures: Hallek: Roche: Consultancy, Honoraria, Research Funding.

Abstract: Introduction: Previous phase II studies have suggested that a combination of FCR may increase the outcome of both untreated and relapsed CLL pts. In order to validate this concept the German CLL study group (GCLLSG) initiated a multicentre, multinational phase III trial, CLL8, to evaluate the efficacy and tolerability of FCR versus FC for the first-line treatment of pts with advanced CLL. Methods and Patients: 817 pts with good physical fitness as defined by a cumulative illness rating scale (CIRS) score (Extermann et al., JCO 1998) of up to 6 and a creatinine clearance (cr cl) □d 70 ml/min were enrolled between July 2003 and March 2006. Pts were randomly assigned to receive 6 courses of either FC (N=409; F 25mg/m2 i.v. d1–3 and C 250 mg/m2 i.v. d1–3; q 28 days) or FC plus R (N=408; 375 mg/m2 i.v. d 0 at first cycle and 500 mg/m2 d1 all subsequent cycles; q 28 days). Both treatment arms were well balanced with regard to age, stage, genomic aberrations and VH status. 64% were Binet B, 32% Binet C and 5% Binet A. The median age was 61 years (range 30 to 81), the median CIRS score was 1 (range 0–8). The overall incidences of trisomy 12 and abnormalities of 13q, 11q23, and 17p13 detected by FISH were 12%, 57%, 25%, and 8%, respectively, with no statistically significant differences between treatment arms. A mean number of 5.2 courses was given in the FCR arm versus 4.8 courses in the FC arm (p=0.006). 74% (FCR) and 67% (FC) of pts received 6 cycles. Dose was reduced by more than 10% in at least one treatment course in 43% (FCR) and 30% (FC) of pts, and in 21% (FCR) and 17% (FC) of all treatment courses given. 17 pts did not receive any study medication, 10 due to violation of enrolment criteria (4 decreased renal function, 2 active secondary malignancies, 2 active infections, 1 autoimmune thrombocytopenia, 1 pt not requiring treatment), 3 due to withdrawal of consent, 2 due to worsened concomitant diseases. 2 pts were lost before start of treatment. 56 pts were not evaluable for response: 17 did not receive any study medication, 16 withdrew consent before interim staging, 7 due to violation of enrolment criteria, 4 discontinued treatment due to toxicity and 12 due to early death (caused by toxicity, progression or secondary malignancy). Prophylactic use of antibiotics or growth factors was not generally recommended in the protocol. Results: At the time of analysis, June 2008, the median observation time was 25.5 months (mo). 761 pts (FCR 390; FC 371) were evaluable for response, 787 pts (FCR 400; FC 387) for PFS and all for OS. The overall response rate (ORR) was significantly higher in the FCR arm (95%; 370/390) compared to FC (88%; 328/371 (p=0.001). The complete response rate of the FCR arm was 52% as compared to 27.0% in the FC arm (p & lt;0.0001). PFS was 76.6% at 2 years in the FCR arm and 62.3% in the FC arm (p & lt;0.0001). There was a trend for an increased OS rate in the FCR arm (91% vs 88% at 2 years p=0.18). Hazard Ratio for PFS was 0.59, for OS 0.76. The largest benefit for FCR was observed in Binet stage A and B with regard to CR, ORR and PFS (A: p=0.01, B: p & lt;0.0001). FCR treatment was more frequently associated with CTC grade 3 and 4 adverse events (47% of FC vs 62% of FCR treated pts). Severe hematologic toxicity occurred in 55% (FCR) versus 39% (FC) of all patients. Significant differences were observed for neutropenia (FCR 33,6%; FC 20,9% p=0.0001) and leukocytopenia (FCR 24%; FC 12,1% p & lt;0.0001) but not for thrombocytopenia (FCR 7,4%; FC 10,8% p=0.09) and anemia (FCR: 5,4% FC 6,8% p=0.42). The incidence of CTC grade 3 or 4 infections was not significantly increased in the FCR arm (18,8% versus 14,8% in the FC arm, p=0.68). Tumor lysis syndrome (FCR 0,2% FC 0,5%) and cytokine release syndrome (FCR 0,2% FC 0,0%) were rarely observed in both arms. Treatment related mortality occurred in 2.0% in the FCR and 1.5% in the FC arm. Multivariate analyses were performed to evaluate factors predicting outcome. Amongst these variables age, sex, Binet stage, CIRS score, renal function (cr cl & lt; 70 ml/min) were independent prognostic factors predicting OS or PFS. Conclusion: Treatment with FCR chemoimmunotherapy improves response rates and PFS when compared to the FC chemotherapy. FCR caused more neutropenia/leukopenia without increasing the incidence of severe infections. These results suggest that FCR chemoimmunotherapy might become the new standard first-line treatment for physically fit CLL patients.

Abstract: 4079 Background: Perioperative ECF is a standard treatment for localized gastric/OGJ adenocarcinoma. However, 5-year survival rate remains below 40%. The FLOT regimen is an effective combination with pathologic response rates in the 15% range. This phase III study compares both regimens in resectable stages. Methods: Pts are stratified by different baseline criteria and randomized to either 3 + 3 perioperative cycles of ECF (epirubicin 50 mg/m 2 , d1; cisplatin 60 mg/m², d1; 5-FU 200 mg/m², d1-d21, qd21) or 4 + 4 cycles of perioperative FLOT (docetaxel 50mg/m 2 , d1; 5-FU 2600 mg/m², d1; leucovorin 200 mg/m², d1; oxaliplatin 85 mg/m², d1, qd14). 5-FU can be replaced by capecitabine in the ECF-arm (ECX). Central pathology is performed. This is a preplanned safety analysis after 300 patients. Results: The ongoing studyhas enrolled 380 of planned 590 pts, so far. 305 pts were included in this analysis. Median age is 62 yrs; 78% of pts are male. The primaries were gastric in 44.9%, OGJ in 50.4% and not evaluable/documented in 4.7% of pts. 281 pts were eligible for safety analyses. Median no. of preoperative cycles was 3 and 4 with ECF/ECX and FLOT, respectively, 35.9% vs. 44.6% of pts (ECF/ECX vs. FLOT) started postoperative chemotherapy (ct) and 22.5% vs 33.1% received all planned cycles. Grade 3/4 neutropenia was observed in 28.0% of ECF/ECX and 45.3% of FLOT pts (p=.0026). Thromboembolic events occurred in 14.1% vs. 5.8% in pts with ECF/ECX vs. FLOT (p=.027). Serious adverse events occurred in 52.1% vs. 47.5% of pts with ECF/ECX vs. FLOT (p=.48). Preoperative delay/interruptions of ct were observed in 71.1% vs. 56.8% of pts with ECF/ECX vs. FLOT (p=.013). Dose modifications of preoperative ct were performed in 27.5% vs. 20.1% of treatment cycles with ECF/ECX vs. FLOT, respectively. 197 pts have undergone surgery so far. Severe surgical morbidity was similar in both arms (ECF/ECX, 19.8%; FLOT, 16.8%). Surgical mortality was observed in 4 and 2 pts with ECF/ECX and FLOT. Toxic deaths were observed in 1 pt each. Conclusions: Perioperative FLOT is feasible and safe. Clinical trial information: NCT01216644.
