    Abstract: FOLFOXIRI plus bevacizumab has demonstrated benefits for metastatic colorectal cancer (mCRC) patients. However, challenges arise in its clinical implementation due to expected side effects and a lack of stratification criteria. Methods The AIO “CHARTA” trial randomised mCRC patients into clinical Group 1 (potentially resectable), 2 (unresectable/risk of rapid progression), or 3 (asymptomatic). They received FOLFOX/bevacizumab +/− irinotecan. The primary endpoint was the 9-month progression-free survival rate (PFSR@9). Secondary endpoints included efficacy in stratified groups, QoL, PFS, OS, ORR, secondary resection rate, and toxicity. Results The addition of irinotecan to FOLFOX/bevacizumab increased PFSR@9 from 56 to 67%, meeting the primary endpoint. The objective response rate was 61% vs. 69% ( P  = 0.21) and median PFS was 10.3 vs. 12 months (HR 0.83; P  = 0.17). The PFS was (11.4 vs. 12.9 months; HR 0.83; P  = 0.46) in potentially resectable patients, with a secondary resection rate of 37% vs. 51%. Moreover, Group 3 (asymptomatic) patients had a PFS of 11.1 vs. 16.1 months (HR 0.6; P  = 0.14). The addition of irinotecan did not diminish QoL. Conclusion The CHARTA trial, along with other studies, confirms the efficacy and tolerability of FOLFOXIRI/bevacizumab as a first-line treatment for mCRC. Importantly, clinical stratification may lead to its implementation. Trial registration The trial was registered as NCT01321957.

    Abstract: 194 Background: Salvage radiotherapy (RT) is often utilized in case of biochemical progression after radical prostatectomy (RP). Here we report the outcomes of the European SAKK 09/10 randomized phase 3 trial with the aim to compare effectiveness and tolerability of conventional vs. dose-intensified salvage RT. Methods: SAKK 09/10 is an open-label, multicenter, randomized phase 3 trial performed in 24 centers in Switzerland, Germany and Belgium. Men with biochemical progression (two consecutive rises with the final PSA 〉 0.1 ng/mL or three consecutive rises) after RP with a PSA nadir of ≤ 0.4 ng/mL, with a PSA ≤ 2 ng/mL at randomization and without clinical evidence of macroscopic disease were recruited. Patients were randomly assigned to either conventional dose RT (64 Gy in 32 fractions) or dose-intensified RT (70 Gy in 35 fractions) directed to the prostate bed. Three-dimensional conformal RTor intensity-modulated RT/rotational techniques were used. The primary endpoint was freedom from biochemical progression (PSA ≥ 0.4 ng/mL and rising). Secondary endpoints included clinical progression-free survival, time to hormonal treatment, overall survival, acute and late toxicity (according to the NCI CTCAE v4.0) and quality of life (according to the EORTC QLQ-C30 and PR25). The trial was registered under NCT01272050 in clinicaltrials.gov. Results: Between 02/2011 and 04/2014, 350 patients were randomly assigned to 64 Gy (n = 175) or 70 Gy (n = 175), of whom 344 aged between 48 to 75 years were assessable for the intention-to-treat population. The median PSA at randomization was 0.3 ng/mL (range, 0.03-1.61 ng/mL). At the time of data cutoff (July 3, 2020), the median follow-up was 6.2 years (IQR 5.5-7.2) and a total of 138 biochemical progression events occurred. The estimated freedom from biochemical progression rate at 6 years was 62.3% (95% CI 54.2-69.4%) and 61.3% (95% CI 53.4-68.3%) for the 64 Gy and the 70 Gy arm, respectively, and the hazard ratio adjusted by stratification factors was 1.14 (95% CI 0.82-1.60; log-rank p = 0.44). No significant difference was found for clinical progression-free survival, time to hormonal treatment and overall survival between the two arms, respectively. Late grade 2 and 3 genitourinary toxicity was observed in 35 (21.2%) and 13 (7.9%) patients treated with 64 Gy, and in 46 (26.3%) and 7 (4%) patients with 70 Gy (p = 0.81). Lategrade 2 and 3 gastrointestinal toxicity was observed in 12 (7.3%) and 7 (4.2%) patients with 64 Gy, and in 35 (20%) and 4 (2.3%) patients with 70 Gy(p = 0.009). Quality of life data will be presented. Conclusions: Dose-intensified salvage RT to the prostate bed was not superior to conventional dose RT. However, dose-intensified salvage RT was associated with higher frequencies of late grade ≥ 2 gastrointestinal toxicity. Clinical trial information: NCT01272050.

    Abstract: 5010 Background: GC has been shown to independently prognosticate outcomes in prostate cancer. Herein, we validate the GC in a European randomized phase III trial of dose escalated SRT after RP. Methods: SAKK 09/10 (NCT01272050) randomized 350 patients with biochemical recurrence after RP to 64Gy vs 70Gy. No patients received androgen deprivation therapy (ADT) or pelvic nodal radiotherapy. A pre-specified statistical plan was developed to assess the impact of the GC on clinical outcomes. RP samples were centrally reviewed for the highest-grade tumor and those passing quality control (QC) were run on a clinical-grade whole-transcriptome assay to obtain the GC score (0 to 1; 〈 0.45, 0.45-0.6, 〉 0.6 for low-, intermediate-, and high, respectively). The primary aim of this study was to validate the GC for the prediction of freedom from biochemical progression (FFBP) using Cox multivariable analysis (MVA) adjusting for age, T-category, Gleason score, persistent PSA after RP, PSA at randomization, and randomization arm. The secondary aims were to evaluate the association of GC with clinical progression-free survival (CPFS) and use of salvage ADT. Results: Of 233 patients with tissue available, 226 passed QC and were included for analysis. The final GC cohort was a representative sample of the overall cohort, with a median follow-up of 6.3 years (IQR 6.0-7.2). GC score (continuous per 0.1 unit, score 0-1) was independently associated with FFBP (HR 1.14 [95% CI 1.03-1.25], p = 0.009). Higher GC scores were independently associated with CPFS, use of salvage ADT, and rapid biochemical failure ( 〈 18 months after SRT). High- vs. low/intermediate-GC showed a HR of 2.22 ([95% CI 1.37-3.58], p = 0.001) for FFBP, 2.29 ([95% CI 1.32-3.98] , p = 0.003) for CPFS, and 2.99 ([95% CI 1.50-5.95], p = 0.002) for use of salvage ADT. Patients with high-GC had 5-year FFBP of 45% [95% CI 32-59] vs 71% [95% CI 64-78] in low-intermediate GC. Similar estimates for GC risk groups were observed in the 64Gy vs 70Gy in GC high (5-year FFBP of 51% [95% CI 32-70] vs 39% [95% CI 20-59]) and in low-intermediate GC (75% [95% CI 65-84] vs 69% [95% CI 59-78]). Conclusions: This study represents the first contemporary randomized controlled trial in patients with recurrent prostate cancer treated with early SRT without ADT that has validated the prognostic utility of the GC. Independent of standard clinicopathologic variables and radiotherapy dose, patients with a high-GC were more than twice as likely than a lower GC score to experience biochemical and clinical progression and receive salvage ADT. This data confirms the clinical value of Decipher GC for tailoring treatment in the postoperative salvage setting.

    Abstract: 3533 Background: FOLFOXIRI/Bevacizumab (Bev) is superior to FOLFIRI/Bev in the TRIBE trial (F Loupakis, NEJM 2014). The CHARTA trial was developed parallel to TRIBE with the same 4-drug-protocol but vs. FOLFOX/B ev as control arm. Methods: From 7/11 to 12/14 250 patients were randomized, including ECOG 0-2, ≥ 1 measurable lesion 〉 1cm, stratified by ESMO-Group 1,2,3 (HJ Schmoll, Ann Oncol 2012). Induction: 6 months, maintenance Capecitabine+Bev until progression or max.12 months, at P reinduction by investigators decision. 25% dose reduction was allowed in cycle 1 + 2 on the investigator’s discretion. Primary EP: significant improvement of PFS-rate @ 9 months (p 〈 0.1, 2-sided Fisher’s-exact test); secondary EP: RR, PFS, OS, toxicity. Results: 241 pts. (1 not elig., 8 prot. violation) are evaluable after a follow up of 31.4 (0.1-51) months. m/f: 65%/35%, age 61y (21-82), ECOG 0-1/2: 96%/4%. The Primary Endpoint was met: PFS @ 9 months 56% vs. 68%, p= 0.086. PFS was improved: 9.8 vs. 12.0 months, HR 0.7 (ns.), identical to TRIBE with 9.7 vs. 12.1 months. Response rate (A/B): CR: 5%/5%, CR/PR 60%/70%, SD 25%/21%, PD 14%/9%. Final OS will be available at the meeting. Toxicity was low to moderate without major differences except ° ¾ diarrhea (12%/16%) and neutrophils (14%/20%). Clinical/molecular prognostic or predictive factors are equally distributed (stratification by ESMO groups) (see table). There are major, but mostly not significant differences in RR/ PFS in most subgroups, however, not strong enough to safely identify patients with high potential to benefit from the 4-drug combination. Therefore, a multivariate analysis to model a common prognostic and predictive risk score is ongoing and will be presented at the meeting. Conclusion: “CHARTA” supports the superiority of FOLFOXIRI/Bev. A combined prognostic and predictive classification is required to better select those patients with most potential benefit from the 4-drug combination. Clinical trial information: NCT01321957.

    Abstract: 3544 Background: FOLFOXIRI/bev is a highly efficacious first line regimen in MCRC. Despite higher rates of neutropenia, diarrhea and stomatitis, FOLFOXIRI/bev is tolerable and feasible in MCRC patients. To date nothing is known about the impact of this regimen on HRQOL. Methods: 250 patients were randomized to FOLFOX/bev (arm A) or FOLFOXIRI/bev (arm B). HRQOL were assessed at baseline, every 8 weeks during induction treatment (6 months) and every 12 weeks during maintenance treatment, using the EORTC QLQ-C30, QLQ-CR29 and QLQ-CIPN20. The mean values of every score were calculated as the average of week 8, 16 and 24 assessment. Test concerning mean values were performed as t-test, with global type I error set at 0.05. HRQOL deterioration and improvement rates were analyzed and compared between treatment groups using chi² tests. Results: For HRQOL analysis, 237 patients were eligible (arm A: 118; arm B: 119). Compliance rate with the HRQOL questionnaires was 95.4% at baseline, 72.6% at week 8, 59.5 % at week 16 and 43.5% at week 24. Whereas mean global quality of life score (GHS/QOL) was similar between arm A and B (59.8 vs. 58.8; p = 0.726), mean scores for nausea/vomiting (9.4 vs. 16.0; p = 0.015) and diarrhea (23.7 vs. 32.1; p = 0.051) significantly or borderline significantly favored arm A during induction period. Furthermore, at week 8 scores of nausea/vomiting (9.2 versus 17.3, p = 0.006) appetite loss (19.5 vs. 29.4; p = 0.035) and financial problems (18.3 vs. 29.5; p = 0.021) and at the end of treatment physical functioning (75.0 vs. 65.8; p = 0.048) were significantly better for arm A compared to arm B. No significant differences were observed in the remaining EORTC scores. The rates of deterioration and improvement between baseline and week 8 of at least 10 points in the EORTC scores were similar (e.g. deterioration-rate GHS/QOL score 21.5% vs. 26.5% for arm A vs. B; p = 0.461). Conclusions: Although no remarkable detriment in HRQOL was noted, the better efficacy of FOLFOXIRI/bev compared to FOLFOX/bev is associated with a decrease in mainly gastrointestinal QOL scores. Further subgroup-analyses will be presented at the meeting. Clinical trial information: NCT01321957.

    Abstract: 658 Background: The 4-drug-regimen FOLFOXIRI+Bevacizumab (Bev) was superior to FOLFIRI+Bev (TRIBE F.Loupakis, NEJM 2014). CHARTA investigates the same 4-drug-regimen vs. FOLFOX+Bev. Methods: 250 patients were randomized from 7/11 to 12/14 to standard FOLFOX+Bev (A) vs. FOLFOXIRI+Bev (B), with dose/schedule as in TRIBE, 25% dose reduction in cycle 1 + 2, if necessary. Incl.criteria: ECOG 0-2, ≥ 1 measurable lesion 〉 1cm; stratified by ESMO-Group 1, 2, 3 (HJ Schmoll et. al., Ann Oncol 2012). Induction: 6 months, maintenance Capecitabine+Bev until progression or max. of 12 months, with reinduction by individual decision. Primary EP: significant improvement of PFS-rate at 9 months (p 〈 0.1, 2-sided Fisher’s-exact test); secondary EP: RR- rate, PFS, OS, sec. resection. Results: Evaluable 241 pts. (1 not elig., 8 prot. violation); m/f: 65%/35%, age 61 yrs. (21-82), left/right: left A: 51, 5%, B: 48, 5%; right A: 45%, B: 55%; ECOG 0-1/2: 96% / 4%, ESMO-group 1/2/3: 29%/ 55%/ 16%. Primary endpoint was met: significantly improved PFS at 9 months 56% vs. 68% (p= 0,086). Preliminary PFS 9,76 vs. 12,0 months (HR 0.77, p=0.61), identical to TRIBE: 9.7 vs. 12.1. Response (A/B): CR: 5/5%, CR/PR 60/70%, SD 25/21%, PD 14/9%; sec. resection: 21/23%. Subgroup - analyses did not show significant differences, except CR / PR left/right (A/B): left 59/68%, right 63/73%; PFS (months) left 10.4/12 (HR 0.69, p=0.03), right: 8.2 /10.7); non-significant improvement in ESMO-group 3 (HR 0.51), RAS-wt (HR 0.67), Koehne-Score High risk HR 0.58; ECOG 1: HR 0.69. QL-Global- Health-Score: slightly worse in A, vs. improved in B. Dose-intensity 〈 70%/ 70-90%/ 〉 90% (A/B): 39/37%/ 18/26%/ 41%/36%; initial dose-reduction 17% of pts. Toxicity: low to moderate without major differences between A & B, except grade ¾ diarrhea 12/16%, neutrophils 14/20%, GI 12/20%. Conclusions: The 4-drug-regimen has superior activity with the same outcome as TRIBE and is well tolerated, without a negative effect of initial dose-reduction, and an improvement of global QoL-Score. Final PFS, OS data and detailed subgroup/multivariate analysis, including Quality of life data, will be presented. Clinical trial information: NCT01321957.

    Abstract: Patients with biochemical failure (BF) after radical prostatectomy may benefit from dose-intensified salvage radiation therapy (SRT) of the prostate bed. We performed a randomized phase III trial assessing dose intensification. Patients and Methods Patients with BF but without evidence of macroscopic disease were randomly assigned to either 64 or 70 Gy. Three-dimensional conformal radiation therapy or intensity-modulated radiation therapy/rotational techniques were used. The primary end point was freedom from BF. Secondary end points were acute toxicity according to the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.0) and quality of life (QoL) according to the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaires C30 and PR25. Results Three hundred fifty patients were enrolled between February 2011 and April 2014. Three patients withdrew informed consent, and three patients were not eligible, resulting in 344 patients age 48 to 75 years in the safety population. Thirty patients (8.7%) had grade 2 and two patients (0.6%) had grade 3 genitourinary (GU) baseline symptoms. Acute grade 2 and 3 GU toxicity was observed in 22 patients (13.0%) and one patient (0.6%), respectively, with 64 Gy and in 29 patients (16.6%) and three patients (1.7%), respectively, with 70 Gy (P = .2). Baseline grade 2 GI toxicity was observed in one patient (0.6%). Acute grade 2 and 3 GI toxicity was observed in 27 patients (16.0%) and one patient (0.6%), respectively, with 64 Gy, and in 27 patients (15.4%) and four patients (2.3%), respectively, with 70 Gy (P = .8). Changes in early QoL were minor. Patients receiving 70 Gy reported a more pronounced and clinically relevant worsening in urinary symptoms (mean difference in change score between arms, 3.6; P = .02). Conclusion Dose-intensified SRT was associated with low rates of acute grade 2 and 3 GU and GI toxicity. The impact of dose-intensified SRT on QoL was minor, except for a significantly greater worsening in urinary symptoms.
