LBA2 Background: Docetaxel (D) improves OS of men with mPrCa who have progressed on androgen deprivation therapy (ADT). We aimed to assess the benefit of upfront chemohormonal therapy for metastatic PrCa. Methods: 1:1 randomization to ADT alone or ADT + D dosed 75mg/m2 every 3 weeks for 6 cycles within 4 month (mos) of starting ADT. Stratification factors: high volume (HV) vs. low volume (LV) disease (HV: visceral metastases and/or 4 or more bone metastases); anti-androgen use beyond 30 days; Age ≥70 vs. < 70 years; ECOG PS 0-1 vs. 2; Prior adjuvant ADT > 12 vs. ≤ 12 mos; FDA approved drug for delaying skeletal related events. Key eligibility criteria: suitable organ and neurological function for D; adjuvant ADT ≤ 24 mos and no progression within 12 mos of adjuvant ADT. OS was the primary endpoint and the study was powered to assess for a 33.3% improvement in median OS (80% power and 1-sided alpha=2.5%). Projected median OS for ADT alone: HV-33 mos; LV-67 mos. Results: 790 men were accrued from 7/28/06 to 11/21/2012: ADT N=393; ADT + D: N=397; balanced for demographic, stratification and disease factors. Median age: 63 years (range: 36 to 91); 98% ECOG PS 0 or 1; 89% Caucasian; 24% prior radiotherapy, 24% prior prostatectomy; HV 64% on ADT and 67% on ADT + D. Data released after 4th interim analysis in Sept 2013 when O’Brien Fleming upper boundary was crossed with 53.1% information. This report reflects 1/16/2014 data with median follow-up of 29 mos with 137 deaths on ADT alone vs. 104 deaths on ADT+D. ADT+D: Grade (G) 3/4 Neutropenic fever: 4%/2%; G3 neuropathy: 1% sensory, 1% motor; 1 death due to treatment (no deaths due to treatment on ADT). Efficacy data is in the table below. After disease progression, 123 pts on ADT alone and 45 pts on ADT + D received docetaxel. Conclusions: ADT + D improves OS over ADT alone in men with HV mPrCa. Longer follow-up is needed for men with LV mPrCa. Clinical trial information: NCT00309985. [Table: see text]

Purpose Docetaxel added to androgen-deprivation therapy (ADT) significantly increases the longevity of some patients with metastatic hormone-sensitive prostate cancer. Herein, we present the outcomes of the CHAARTED (Chemohormonal Therapy Versus Androgen Ablation Randomized Trial for Extensive Disease in Prostate Cancer) trial with more mature follow-up and focus on tumor volume. Patients and Methods In this phase III study, 790 patients with metastatic hormone-sensitive prostate cancer were equally randomly assigned to receive either ADT in combination with docetaxel 75 mg/m2 for up to six cycles or ADT alone. The primary end point of the study was overall survival (OS). Additional analyses of the prospectively defined low- and high-volume disease subgroups were performed. High-volume disease was defined as presence of visceral metastases and/or ≥ four bone metastases with at least one outside of the vertebral column and pelvis. Results At a median follow-up of 53.7 months, the median OS was 57.6 months for the chemohormonal therapy arm versus 47.2 months for ADT alone (hazard ratio [HR], 0.72; 95% CI, 0.59 to 0.89; P = .0018). For patients with high-volume disease (n = 513), the median OS was 51.2 months with chemohormonal therapy versus 34.4 months with ADT alone (HR, 0.63; 95% CI, 0.50 to 0.79; P < .001). For those with low-volume disease (n = 277), no OS benefit was observed (HR, 1.04; 95% CI, 0.70 to 1.55; P = .86). Conclusion The clinical benefit from chemohormonal therapy in prolonging OS was confirmed for patients with high-volume disease; however, for patients with low-volume disease, no OS benefit was discerned.

8034 Background: Nintedanib (N) is an oral inhibitor of VEGFR, FGFR, and PDGFR. This global phase 3 study investigated the safety and efficacy of N + pemetrexed (PEM) vs placebo (P) + PEM in patients (pts) with advanced, non-squamous NSCLC previously treated with chemotherapy. Methods: Pts were randomized 1:1 to N 200 mg po bid + PEM 500 mg/m2 iv q21d (n=353, Arm A) or P + PEM (n=360, Arm B). Continuation until PD or unacceptable toxicity with N, P, PEM, or a combination was permitted. 1° endpoint was centrally reviewed PFS. The null hypothesis was tested on the ITT population after 394 events had occurred (two sided α=5%). 2° endpoints included OS, investigator-assessed PFS, response rate (RR), safety, and QoL. Results: Baseline pt characteristics were balanced between Arm A vs B (median age 59 y, female 45–42%, ECOG PS 1 62-61%, adenocarcinoma 95–93%, prior bevacizumab 8%). Based on a planned DMC futility analysis of investigator-assessed PFS, enrolment was halted after randomizing 713/1300 planned pts (no safety issues identified). Ongoing pts were unblinded and follow-up continued per protocol. Subsequent ITT analysis of the 1° endpoint (centrally reviewed PFS) favored Arm A vs B (median 4.4 vs 3.6 mo, HR 0.83 [95% CI: 0.7–0.99], p=0.04). Disease control was also significantly improved in N-treated pts (61 vs 53%, odds ratio 1.37, p=0.039). No difference in OS (HR 1.03) or RR (9%) was found. Exploratory analyses identified time since start of 1st-line therapy as a predictive marker of improved outcome with N + PEM (ASCO 2013). There was no increase in SAEs or G5 AEs with N + PEM. Addition of N to PEM resulted in a higher incidence of ≥G3 elevated ALT (23 vs 7%), elevated AST (12 vs 2%), and diarrhea (3 vs 1%), but no difference in ≥G3 hypertension, bleeding, thrombosis, mucositis, or neuropathy. Conclusions: The 1° endpoint was met even though the study was stopped prematurely. Treatment with N + PEM significantly improved centrally reviewed PFS vs P + PEM in pts with advanced non-squamous NSCLC previously treated with chemotherapy, and had a manageable safety profile.

Descriptive Statistical Analysis

241 Background: Androgen deprivation represents the standard treatment for PCA with osseous metastases. We explored the role of cRP in the largest cohort of contemporary patients with mPCA treated in 4 tertiary referral centres. Methods: A total of 114 patients with mPCA, lymph node, osseous or visceral metastases underwent cRP. Surgery related complications (Clavien-Dindo classification) and functional outcome were analysed. Oncologic outcome parameters such as cancer specific & overall survival as well as biochemical and clinical-free survival were evaluated using descriptive statistical analysis. Results: Mean patient age was 61 (42-69) years. Mean and median follow-up was 39.7 months (7-75) and 47 months (28-96), resp. 93 (81.6%) and 21 (18.4%) patients had low volume and high volume mets, resp.,. 80(70.2%) pts underwent neoadjuvant ADT with LHRH analogues. Surgical approach was open retropubic RP in 104 (92%) pts and 2 (1.8%), 10 (8.8%) and 101 (89.4%) pts underwent no, limited or extended pelvic LAD, resp. Adjuvant therapy was delivered in 99 (86.8%) pts. Pathohistology revealed significant vital PCA in 100% of cases: n = 16 (14.0%) exhibited pT4a, n = 21 (18.4%) had pT2 and the remainder had pT3a/b PCA. Positive lymph nodes or positive surgical margins were identified in 61.6% and 36.8%, resp.. 110 (96.5%) are alive and 66.7% are relapse-free. 74 (64.9%) pts did not experience any surgery related complications; 15 (13.1%) pts experienced Clavien Dindo grade IIIb/IV complications and underwent reintervention. Low versus high volume (32.2% vs 50%, p = 0.03), PSA at cRP < 1ng/ml vs PSA > 4 ng/ml, (18.9% vs 45.6%, p = 0.02) were associated with relapse. Low vs high volume disease (7.1% vs 32.1%), PSA < 4ng/ml vs PSA > 4 ng/ml (6.1% vs 47.8%) and neoadjuvant vs no neoadjuvant therapy (8.75% vs 24.2%) were associated with Clavien-Dindo IIIB complications (p < 0.05). Conclusions: cRP is feasible in men with mPCA independent on the extent of disease with a low rate of significant complications and good functional outcome. About two thirds of the patients remain relapse-free after a median follow-up of close to 4 years. cRP might be an individualized treatment option in the multimodality management of mPCA.

4040 Background: PD-1 inhibitor and chemotherapy have shown significant clinical benefits in 1L-treatment of G/GEJ. While it is not clear for locally advanced stage. The aim of this single-arm phase Ib trial is to assess the feasibility of sintilimab (PD-1 inhibitor) in combination with cCRT in locally advanced GC. Methods: Patients (pts) with initial histopathologically confirmed G/GEJ adenocarcinoma, diagnosed as locally advanced III-IVA per AJCC 8th and ECOG PS of 0-1 were eligible. Sintilimab (200mg, iv, Q3W) was given with CRT sandwich in sequence of one induction chemotherapy (S-1+Nab-PTX), weekly Nab-PTX(80-100mg/m2, d1, d8, d15, d22), concurrent radiotherapy (45Gy/1.8Gy*25f), and one consolidation chemotherapy (S-1+Nab-PTX). Pts received three additional combinations of sintilimab and chemotherapy after surgery or investigator’s best choice for unresectable pts after planned therapy. The primary endpoint was pCR and a Simon two-stage was employed at first 9 pts. This interim analysis was pre-planned after finishing stage I assessment. Accrual is ongoing with another 25 in next stage. Results: In the first stage, 5 out of 9 pts achieved pCR and passed to next stage. As of 7th Feb 2021, 28 pts met inclusion criteria with median age 67 yrs (range 47-81), men 86%, PS 1 25%, cT3/4a/4b 28%/54%/18%, cN1/N2/N3 7%/50%/43% and Borrmann II/III/IV 57%/18%/25%. The location on GEJ and G was 14% and 86%. Of 23 pts completed neoadjuvant, all were evaluated as D2-surgery feasibility. 19 pts had completed gastrectomy (4 pts waiting for surgery) with pCR 42.1% (8/19), MPR (≤10% viable tumor cells) 73.7% (14/19) and R0 resection 94.7% (18/19). Down-staging to pT0 and pN0 were both observed in 42.1%. The median follow-up was 5.8m unavailable for survival evaluation at present. Grade (gr) 3-4 TRAE occurred in 39.3% (11/28) pts with most common events as myelosuppression (39.3%) and increased transaminase (10.7%). IrAEs occurred in 21.4% (6/28) pts with one gr 4 hepatitis and others gr 1-2. Peri-operative complications occurred in 3 pts with gr 1-2 pneumonia, increased transaminase, and ileus. No death or unexpected toxicity observed. Conclusions: SHARED interim analysis demonstrated a promising feasibility of sintilimab in combination with cCRT with preliminary impressive pCR & MPR and acceptable toxicity in phase III-IVA G/GEJ cancer. These results warrant further accrual and evaluation. Clinical trial information: ChiCTR1900024428.

Background: Both EPO levels and anemia have shown prognostic value in several cardiac disorders. An observational study with a prospective follow-up was performed to investigate their independent prognostic roles in severe aortic stenosis.Methods: An up to 36-month follow-up of consecutive patients with severe aortic stenosis undergoing TAVR in a high-volume center was performed. Patients with eGRF &lt;30 mL/min/1.73 m2 were excluded. EPO levels and/or anemia status and its association with mid-term mortality were assessed.Results: Out of 407, 360 met eligibility criteria. Median age was 83 years, with 71.4% having a NYHA class III/IV. Anemia was present in 51.9%, and iron deficiency in 52.8%. Median (IQR) EPO levels were 14.4 (9.30–24.30) mIU/mL. Median follow-up was 566 days. Anemia was associated with overall mortality (HR 2.40, 95% CI 1.51–3.80, p &lt; 0.001). Higher logEPO levels were associated with mid-term mortality (HR 4.05, 95% CI 2.29–7.16, p &lt; 0.001), even after adjusting for clinically and/or statistically relevant factors (multivariate HR 2.25, 95 CI 1.09–4.66, p = 0.029). Kaplan-Meier analyses showed early diverging curves for anemia vs. non-anemia, whereas curves for patients in various EPO level quartiles started to diverge at about 100 days, with differences consistently increasing during the subsequent entire follow-up period.Conclusions: Differently from anemia, which was a strong predictor for both early and late mortality in severe aortic stenosis after TAVR, independent prognostic value of EPO only emerged after post-TAVR recovery. EPO prognostic value was independent from anemia and mild-to-moderate renal dysfunction. High EPO levels could be useful to identify patients with severe aortic stenosis showing a compromised mid-term survival in spite of TAVR use and independently from early TAVR results.

8006 Background: The GITMO-IIL trial evaluated if an intensified treatment with ASCT is better than conventional chemotherapy (both supplemented with Rituximab) in high-risk FL at diagnosis. Methods: Eligibility required a FL with aaIPI>1 or IIL>2 score and an age of 18–60. Primary endpoint was EFS. The analysis was intention to treat. Secondary endpoints were PFS, DFS, OS, rate and prognostic value of MR. R-HDS and CHOP-R have been already described (Ladetto et al ASH 2005, Rambaldi et al Blood 2002). Planned sample size was 240 to detect a 20% absolute increase in the 3-years EFS. However the trial was stopped at 136 pts due to R-HDS superiority in EFS at a planned interim analysis. Cross-over was allowed after CHOP-R failure. Centralized PCR-based molecular analysis was planned on BM cells. Results: Age, stage, LDH, bulky disease, B-symptoms ECOG PS, extranodal disease aaIPI, IIL and retrospectively assigned FLIPI were similar in the two arms. CRs were 59% with CHOP-R and 85% with R-HDS (p<0.001). At a median follow-up of 39 months EFS and PFS are 36% and 38% for CHOP-R and 66% and 72% for R-HDS. OS is 83% in each arm. 67% of relapsed R-CHOP pts underwent R- HDS. MRs were 44% after CHOP-R and 80% after R-HDS (p<0.001). MR was associated to a better PFS (p<0.001). Of note, 3yrs PFS of pts with or without MR was similar in the two arms (MR: 67% with CHOP-R and 76% with R-HDS) (no MR: 25% for CHOP-R and 32% for R-HDS). MR was the strongest independent prognostic factor for PFS, EFS and DFS by multivariate analysis. Conclusions: This is the first phase III trial including MR analysis in a high proportion of pts and comparing intensified versus conventional therapy in the rituximab age. This trial indicates that: a) R-HDS has a better EFS and PFS in truly high-risk FL patients; b) MR is the strongest outcome predictor available in FL; c) the similar outcome in pts achieving (or not achieving) MR, regardless of treatment received, indicates that the superior performance of R-HDS is mostly due to its superior MR rate.

8567 Background: Vemurafenib (vem) has been FDA approved for the treatment of unresectable or metastatic BRAFV600E mutated melanoma since August 2011 based on results of a randomized phase III study (treatment-naive) and a single arm phase II study (previously treated). We report results of an expanded access study that allowed appropriate patients (pts) to receive vem until the drug was approved. Methods: Eligible pts had metastatic melanoma with a BRAFV600E mutation as detected by the cobas 4800 BRAFV600 Mutation Test. Enrolled pts received oral vem 960 mg b.i.d. Adverse events (AEs) were evaluated for vem-related toxicities; tumor responses were assessed using RECIST 1.1. Results: 29 US sites screened 745 pts and enrolled 374 from December 2010 until October 2011. The following results are based on a median follow up time and treatment duration of 2 months. At baseline, mean age of pts was 54 y with 22% of pts ≥65 y; 75% had stage M1c disease; 29% had received radiotherapy for brain metastases. 19% of pts were ECOG PS 2 or 3; 71% of pts had prior systemic therapy for metastatic melanoma (21% 1 regimen; 50% ≥2 regimens). 50 pts had prior adjuvant treatment. At data cut-off, 243 pts had sufficient follow-up time for tumor assessment. In this group, the unconfirmed overall response rate was 52% (95% CI, 46 to 59). The median time to response was 1.8 months. Based on 240 pts with available ECOG PS status at time of analysis, response rate was 53% for pts with ECOG PS 0 or 1 (n=209), and 45% for pts with ECOG PS 2 or 3 (n=31). 370 pts were evaluable for safety analysis. The most common vem-related AEs were rash (36%), arthralgia (33%) and fatigue (21%) with the majority (~90%) of grade 1 or 2. 25 vem-related serious AEs were reported in 5.4% of pts with a slightly higher rate of pts with ECOG PS 2 or 3 (8.7%) compared to ECOG PS 0 or 1 (4.7%). 18% of pts missed at least one dose and 11% of pts required dose reduction of at least one level due to AEs. Conclusions: This expanded access study, with its limited follow-up time, confirms the established rapid and high tumor response rate with vem. No new safety signals were detected. Compared to the overall population, pts with an ECOG PS 2 or 3 demonstrated a similar benefit.

LBA4003 Background: CRT is one of the best treatment options for localized EC. As new combinations are required to improve safety and survival, we launched a randomized phase II study to assess the complete response (CR) rate of CRT with FOLFOX versus 5FU/cisplatin in 97 pts with localized EC (Conroy 2010). The trial having met its objectives, it has been pursued as a phase III trial. Stratified randomization was performed centrally in a 1:1 ratio according to histological type, pretreatment weight loss in the prior 6 months (<10% vs ≥10%), ECOG PS (0 vs 1 vs 2), and center. Methods: Pts with technically unresectable cancer or those with surgical contraindications or who refused to undergo surgery were eligible. Eligibility criteria also included age >18 years (y), PS ≤ 2, previously untreated adenocarcinoma or squamous cell EC (any T, N0 or N1, M0 or M1a). The radiation dose was 50 Gy (2Gy/fr) 5 d/wk for 5 wks in both arms. In Arm A, pts received 6 bimonthly cycles (cy): oxaliplatin 85 mg/m2 d1 and leucovorin 200 mg/m2 followed by 5-FU 400 mg/m2 bolus d1 then 1,600 mg/m2 46h continuous infusion (ci) ; the first 3 cy were delivered during RT, the 3 other after. In Arm B, pts received 4 cy: cisplatin 75 mg/m2 d1 followed by 5FU 1,000 mg/m2/d ci d1-4, the first 2 cy during RT and 2 other after. The primary endpoint was PFS. Main secondary endpoints were OS, grade 3-4 toxicities, and quality of life. A total of 266 pts would provide 90% power to detect a 20% 3y-PFS difference (α=0.05). Results: 267 pts were enrolled between 10/2004 and 08/2011. Treatment cohorts were well balanced: male 81%; median age 61 y; PS 0 53%, squamous cell 85.8%, stage III 52%, IVA 6.0% and IVB 3.0%. Full treatment was delivered to 67.9% and 72.2% of pts in arms A/B, respectively. 7 toxic deaths occurred in each arm. Grade 3/4 toxicities per pt (%) in arms A/B were neutropenia 30.6/31.3, febrile neutropenia 5.3/7.0, anemia 5.4/11.0, asthenia 17.6/10.2, respectively. The median FU time was 25.3 mos. 3y-PFS was 18.2/17.4 % (HR=1.07; 95%CI =0.80-1.43) and median OS was 20.2 /17.5 m (HR=1.06; 95%CI =0.77-1.46). Conclusions: CRT with FOLFOX does not improve PFS compared to cisplatin and 5-FU and has similar toxicities.

9013 Background: Dabrafenib is a selective BRAF inhibitor with demonstrated efficacy in BRAF V600E-positive mutation in MM. The primary analysis of BREAK-3 (NCT01227889) compared progression-free survival (PFS) in patients (pts) with BRAF V600E-positive mutation MM treated with dabrafenib or DTIC. Methods: Median PFS for dabrafenib of 5.1 months (mo) and study methods were previously described (Hauschild A, et al. Lancet. 2012,380:358–365). Independent review ended at the primary analysis. PFS was updated in Jun 2012 at median follow-up of 10.5 mo for dabrafenib (67% of PFS events), and 9.9 mo for DTIC. Median overall survival (OS) was not reached, so another analysis of OS and safety was performed with data as of Dec 2012, at which time the median follow-up was 15.2 (dabrafenib) and 12.7 (DTIC) mo. PFS of subjects who crossed over was also evaluated at that time. Results: PFS hazard ratio was 0.37 [95% CI; 0.23, 0.57]; median PFS was 6.9 mo dabrafenib and 2.7 mo DTIC. In Dec 2012, 36/63 DTIC pts crossed over; median PFS was 4.3 [95% CI; 4.1, 6.1] mos. OS is presented in the Table.The four most common adverse events (AE) on the dabrafenib arm were hyperkeratosis (39%), headache (35%), arthralgia (35%), and pyrexia (32%). Serious AEs ≥ 5% on the dabrafenib arm included cutaneous squamous cell carcinoma/keratoacanthoma (10%) and pyrexia (5%). Conclusions: Longer follow-up confirms the benefits of dabrafenib on PFS and response rate. Median OS in the dabrafenib arm was over 18 mo and over 15 mo in the DTIC arm. OS results are confounded by crossover of DTIC pts to dabrafenib and likely by subsequent therapy after progression. The effects of subsequent therapy results will be investigated. The safety profile had no significant changes. Clinical trial information: NCT01227889. [Table: see text]
