8505 Background: Although level 1 evidence is lacking, the majority of patients (pts) with LSCLC are treated with a high dose QD TRT regimen in clinical practice. CALGB 30610/RTOG 0538 was designed to determine if administering high dose TRT would improve overall survival (OS), compared with standard 45 Gy BID TRT, in LSCLC pts treated with chemoradiotherapy. Methods: Eligible pts had LSCLC, ECOG performance status (PS) 0-2 and regional lymph node involvement excluding contralateral hilar or supraclavicular nodes. This phase 3 trial was conducted in 2 stages. In the first stage, pts were randomized 1:1:1 to 45 Gy BID over 3 weeks, 70 Gy QD over 7 weeks, or 61.2 Gy concomitant boost (CB) over 5 weeks. For the second stage, the study planned discontinuation of one high dose arm based on interim toxicity analysis with patients then randomized 1:1 in the two remaining arms. TRT was given starting with either the 1st or 2nd (of 4 total) chemotherapy cycles. The primary endpoint was OS measured from date of randomization. Results: The trial opened 03/15/2008 and closed 12/01/2019 upon completing accrual, with the CB arm discontinued 3/11/2013 after interim analysis. This analysis includes 638 pts randomized to 45 Gy BID TRT (n = 313) or 70 Gy QD TRT (n = 325). Median age was 63 years (range 37-81), the majority of pts were Caucasian (86%), female (52%), and with ECOG PS 0-1 (95%). After median follow-up of 2.84 years (IQR:1.35 -5.61) for surviving pts, QD compared to BID did not result in a significant difference in OS (HR 0.94, 95% CI: 0.76-1.2, p = 0.9). Median, 2- and 4-year OS for QD were 30.5 months (95% CI: 24.4-39.6), 56% (95% CI: 0.51-0.62), and 39% (95% CI: 0.33-0.45), and for BID 28.7 months (95% CI: 26.2-35.5), 59% (95% CI: 0.53-0.65), and 35% (95% CI: 0.29-0.42). QD also did not result in a significant difference in PFS (HR 0.96, 95% CI: 0.78-1.18, p = 0.94). Most grade 3+ hematologic and non-hematologic adverse events (AEs) were similar between cohorts. Rates of grade 3+ febrile neutropenia, dyspnea, esophageal pain and dysphagia for QD were 12.6%,7%, 11.6% and 11.3%, and for BID 13.6%, 4%, 11.2 % and 9.5%. Grade 5 AEs were reported in 3.7% and 1.7% of the QD and BID cohorts, respectively. Results will be updated at presentation. Conclusions: High dose QD TRT to 70 Gy did not significantly improve OS compared with standard 45 Gy BID TRT. Nevertheless, favorable outcomes on the QD arm provide the most robust evidence available supporting high dose once-daily TRT as an acceptable option in LSCLC. Outcomes from this study, the largest conducted in LSCLC to date, will help guide TRT decisions for this patient population.

4653 Background: D-based chemotherapy is a burgeoning option for men with advanced HRPC. Alone or in combination with E, D has been shown to improve median survival. In this study we tested the combination of D with two different doses of E in patients (pts) with HRPC to improve response rates and to lower side effects. Methods: 72 metastatic HRPC pts were randomly assigned to receive D (70 mg/m2 IV, d2, q3w) and E (3 × 280 mg/d PO starting 1 day prior to D, for 5 consecutive days) for arm A or E (3 x 140 mg/d PO starting 1 day prior to D, for 3 consecutive days) for arm B. Premedication with oral DX at a total daily dose of 16 mg, in divided doses two times a day was administered in arm A on day 1 to 5 and in arm B on day 1 to 3. Initially, 6 cycles were administered and repeated after significant PSA rise. Pts were monitored for PSA response, time to progression (TTP), survival and toxicity. Results: PSA declines of ≥75%, ≥50% and ≤50% were 36.8%, 55.3% and 44.7% in arm A and 38.2%, 67.6% and 32.4% in arm B, respectively (P = .442). TTP in Arm A and Arm B were 11 months (95% CI, 7–14) versus 14 months (95% CI, 8–19), P = .6911) and overall survival 21 months (95% CI, 6–35) versus 22 months (95% CI, 18–27), respectively, (P = .4149). The primary treatment-related side effects observed in arm A and arm B were granulocytopenia (34% and 29%, P = .663) and thrombotic complications caused by E (four pts (11%) and one pt (3%), respectively, P = .206). Associated baseline factors with overall survival in univariate analysis were ECOG performance status (P < .001), hemoglobin level (P < .001), bone pain (P < .001), and PSA (P < .097) and in multivariate analysis ECOG performance status (95% CI, 2.9–13.9) and bone pain (95% CI, 3.2–20.1), (P < .001). Conclusions: In this randomized phase II study the combination of D and E had substantial activity in HRPC. We did not find a statistically significant difference of higher dose of E in combination with D compared to a lower dose of E and D regarding PSA response, TTP and survival. However, there was a tendency of higher toxicity in the high dose E group. These treatment-related toxicities were mainly hematologic and manageable. The results of this study support the assertion that estramustine is not necessary in docetaxel-based treatment regimens. No significant financial relationships to disclose.

e19092 Background: Metastatic lung cancer patients are at best treated palliatively. We evaluated the effects of metronomic chemotherapy on survival outcomes in this population. Methods: Thirty four subjects with treatment refractory (n=26) and treatment naive (n=7) metastatic lung cancer were included in a open label single arm efficacy study of metronomic chemotherapy. Patients were given a chemotherapy regimen of Tab. Cyclophsophamide 50 mg once daily and cap. etoposide 50 mg once daily, 3 weeks on and one week off in 28 day cycle over a minimum period of 3 months or until the progression of their disease whichever was earlier. Patients were assessed for treatment response using RECIST criteria (version 1.1) and duration of progression free survival and overall survival. Data were analysed using Kaplan Meier survival analysis. Results: The mean age of the study population was 63.4 ±11.2 years. The mean duration of metronomic chemotherapy was 94.9 ±60.4 days. Overall 64.7% had progressive disease and 26.5% had stable disease. There was a significant improvement in overall survival in those with ECOG performance status of 1 compared to ECOG status of 2 (median survival =240 vs.52 days, Log Rank Mantel Cox =11.32, p=0.001) and pathology grade 2 compared to grade 3 (median survival =200 vs. 37 days, Breslows Wilcoxon =5.76, p=0.02) and stable disease on RECIST compared to progressive disease following metronomic chemotherapy (Median survival =360 vs. 50 days, Log Rank Mantel Cox =8.68, p=0.003). There was also a significant improvement in progression free survival in those with ECOG performance status of 1 compared to ECOG status of 2 (median survival =98 vs. 52 days, Log Rank Mantel Cox =6.62, p=0.001) and in grade 2 compared to grade 3 disease (mean survival =97 vs.32 days, Log Rank Mantel Cox =4.73, p=0.03). Tumor load and multiple organ sites of disease did not seem to influence survival. Conclusions: The results suggest stable response in about one third of study population, favorable progression free and overall survival rates following metronomic chemotherapy. Performance status is important predictors in this category of population.

200 Background: In the phase 3 PREVAIL trial, enzalutamide (ENZA), an androgen receptor inhibitor, improved overall survival (OS) and radiographic progression-free survival (rPFS) relative to placebo (PBO) in chemotherapy-naïve men with mCRPC. Methods: PREVAIL randomized 1,717 patients (pts) with asymptomatic or minimally symptomatic chemotherapy-naïve mCRPC 1:1 to ENZA 160 mg daily or PBO. Coprimary endpoints were OS and rPFS. This prespecified analysis evaluated the impact of age (≥ 75 vs < 75 years) on efficacy and safety. Results: In PREVAIL, 609 (35%) pts were aged ≥ 75 years. This older subset had several poorer baseline prognostics relative to those aged < 75 years: worse ECOG performance status (ECOG 1: 45.0% vs 24.7%), higher prostate-specific antigen (PSA; 73.3 vs 37.3 ng/mL) and more cardiovascular disease (26.9% vs 16.5%). In both older and younger pts, ENZA improved OS, rPFS and time to PSA progression (Table). Pts aged ≥ 75 years in both the ENZA and PBO groups combined had a higher rate of grade ≥ 3 adverse events (46% vs 37% in younger pts) and among enzalutamide-treated men more older pts reported falls (any grade; ENZA 19% and PBO 8%) than younger pts (ENZA 7% and PBO 4%). Fewer pts ≥ 75 years received subsequent antineoplastic therapies. Conclusions: In PREVAIL, efficacy outcomes in elderly (≥ 75 years) and younger (< 75 years) pts with chemotherapy-naïve mCRPC were comparable and pts consistently benefited from ENZA treatment. Safety with ENZA was similar in both age groups, although older pts reported a higher incidence of falls and received fewer subsequent antineoplastic therapies.

e15599 Background: The role of the second line chemotherapy in advanced gastric cancer was not clear, but possibility of prolongation of survival is open question. Irinotecan is promising agents in gastric cancer and this phase II study evaluated the efficacy and safety of combination chemotherapy with irinotecan, high dose of 5-fluorouracil (5-FU) and leucovorin in taxane and cisplatin based chemotherapy refractory metastatic gastric cancer. Methods: Eligible criteria were as followed; histologic confirmed adenocarcinoma of stomach, previously treated with taxane and cisplatin, age≥18, Eastern Clinical Oncology Group (ECOG) performance status of 1 or less, adequate organ function. Irinotecan (150 mg/m2) as a 30-min infusion and leucovorin (200 mg/m2) as a 15-min infusion were given on day 1, followed by 5-FU 400 mg/m2bolus infusion then 5-FU 2,400 mg/m2 as a 48-hour continuous infusion. This cycle was repeated every 2 weeks until disease progression or unacceptable toxicities. Results: Thirty-four patients were enrolled. The median age was 57 years (range 27–73 years), and the ECOG performance status of all patients was 1. All patients were evaluable for safety and survival and twenty seven patients (79.4%) were evaluable for tumor response. The overall response rate was 18.5% (95% CI: 3.9–33.1). The median progression free survival and overall survival were 4.6 (95% CI: 2.4–6.9) and 9.3 months (95% CI: 5.2–13.4), respectively. Greater than grade 3 haematological toxicities were neutropenia in nine (26.5%), febrile neutropenia in one (2.9%) and thrombocytopenia in one patient (2.9%). The major non-haematological toxicity was asthenia, but most of patients showed grade 1 or 2. Greater than grade 3 non- haematological toxicities were elevated AST/ALT in four (11.8%), hyperbilirubinemia in two (5.9%), nausea in two patients (5.9%). Conclusions: This results showed that the combination chemotherapy with irinotecan, 5-FU and leucovorin was well tolerated and active in taxane and cisplatin refractory patients.

AbstractBackgroundPatients with high-grade glioma (HGG) are at increased risk of venous thromboembolism (VTE), throughout the course of disease. Prophylactic anticoagulation is not established among patients with HGG, outside of perioperative context, due to potential for intracranial hemorrhage (ICH) and the limited data available for predictive VTE scores in primary brain tumors. The aim of this study was to characterize VTE prevalence in adult patients with HGG and assess ICH risk during therapeutic anticoagulation.MethodsRetrospective analysis of patients diagnosed with HGG at our institution, between 2009 and 2018. All adult patients proposed to systemic treatment were included into this study. Exclusion criteria was anticoagulation previous to diagnosis. VTE was defined as any radiographic-confirmed thrombus in the venous system. Risk factors of interest for VTE and bleeding risk scores were analyzed by chi-squared test and multivariate logistic regression. Survival analysis was performed using Kaplan-Meier method.ResultsA total of 410 patients were included of whom 31 (7,8%) developed a VTE, including 22 deep vein, 6 pulmonary and 3 central venous thrombosis. Twenty-nine patients with VTE had a WHO grade 4 glioma and 2 patients had grade 3 (anaplastic astrocytoma and oligodendroglioma).In 22 cases, the VTE occurred during systemic treatment, more frequently during Temozolomide (n=15), followed by Irinotecan+Bevacizumab (n=6), Lomustine+Bevacizumab (n=1) and PCV (n=1). The median time between diagnosis and VTE was 10,11 months (95CI 6,46-14,79). Khorana score, age, ECOG performance status, smoking and obesity did not significantly differ in the VTE population. All VTE were initially treated with low molecular weight heparin (LMWH), of which 64.5% maintained LMWH, and the remainder switched to warfarin (19.4%) or to direct oral anticoagulant (16.1%). Six patients (19,4%) had spontaneous ICH under anticoagulation. Patients with grade 3 glioma (p=0,032) had significantly higher rates of ICH than grade 4. Patients with higher ECOG had significantly higher risk of ICH (OR 3,23 (95CI 1,18-8,81), p=0,022). HAS-BLED and ACCP bleeding scores were not associated with ICH. There was no significant difference in overall survival for TVE or ICH.ConclusionAccording to our data, ICH occurred in nearly 20% anticoagulated patients with HGG, as described in literature, and did not correlate with poorer prognosis. High ECOG performance status was an independent risk factor for ICH. Further effort towards better prediction models for VTE and ICH in HGG is warranted.

Abstract Granulocyte colony-stimulating factor has been shown to decrease the time to neutrophil recovery following autologous PBSCT. Therefore, it was hypothesized that a single injection of pegfilgrastim (P) would mimic the role of filgrastim (F), resulting in at least an equivalent shortening of post-PBSCT neutropenia. PBSCT eligible NHL patients over the age of 18 years with preserved end-organ function were identified prior to the administration of high-dose chemotherapy, and following adequate stem cell harvest and cryopreservation (ie, >2.5 x 106 CD34+ cells/kg). All patients received either standard BEAM or BEAC high-dose chemotherapy (HDC). Prior to HDC, patients were randomly assigned to receive either P at a fixed-dose of 6 mg on Day +1(Arm A), or weight-based, dose-adjusted F rounded to the nearest prefilled syringe beginning on Day +1(Arm B) following transplantation. Between July 2003 and April 2007, 101 eligible patients were enrolled within our transplant network. Three patients were deemed ineligible (CHF death, patient withdrew consent, other). The analyses and results presented below outline the remaining 98 patients. The demographic characteristics of both arms were well-balanced with regards to stage at diagnosis, stage at treatment, ECOG Performance Status, histology, and prior therapy. The comparison of P vs F is summarized in the table below. Incidence of Grade 3–4 adverse events were comparable in both arms as was transplant-related mortality. In conclusion, administration of pegfilgrastim post-auto PBSCT appears to be equivalent to multiple daily dosing of filgrastim, and might be considered in lieu of filgrastim obviating the need for multiple injections.

Abstract Background: Dasatinib (BMS-354825) is a multi-targeted kinase inhibitor of BCR-ABL and SRC. Based on its high level of activity in pts with CML-CP who are resistant to or intolerant of imatinib (IM), we initiated a phase II trial to study the efficacy and safety of dasatinib in pts with previously untreated CML-CP. Methods: The primary objective was to estimate the proportion of pts attaining major molecular response (BCR-ABL/ABL ratio ≤ 0.05% in our lab) at 12 months (mo). All pts received dasatinib orally 100 mg/day, and were randomized to either a 50 mg-twice-daily (BID) or a 100 mg-once-daily (QD) schedule. Dose escalation to 140 mg/day and 180 mg/day for poor response or dose reduction to 80 mg/day and 40 mg/day for toxicity, maintaining the same schedule, was allowed. Results: Thirty-seven pts have been enrolled between November 2005 and June 2007 (19 on the QD schedule, 18 BID). Median age was 41 years (yrs) (range 18–76 yrs). Nine (24%) of the pts were Sokal intermediate-risk and 3 (8%) were high-risk. Median baseline WBC count was 29.1 x 109/L (range 3.4–300.0). Three pts had clonal evolution at start of therapy. At 3 mo, complete hematologic response (CHR) was achieved in all pts,major cytogenetic response occurred 31/33 (94%), and complete cytogenetic response (CCyR) in 26/33 (79%) evaluable pts. After 6 mo of therapy, 30/32 (94%) evaluable pts had achieved CCyR. This compares favorably with results obtained in historical controls with IM at standard (400 mg) and high-dose (800 mg) at our institution: At 12 mo, 8/25 (32%) evaluable pts had achieved a major molecular response. Responses are similar in both treatment schedule groups. The most common non-hematologic adverse events (AE) included fatigue (n=22), musculoskeletal pain (n=20), headache (n=19), and dizziness (n=14), and were predominantly grade (grade 1–2). Grade 3–4 non-hematologic toxicity (regardless of causality) included headache, pain, rash, neuropathy and memory impairment (1 each). Pleural effusion occurred in 5 (14%) pts (all grade 1–2). Grade 3–4 hematologic toxicity (transient) included neutropenia in 4 (11%) pts, thrombocytopenia in 4 (11) pts, and anemia in (5%). With a median duration of therapy of 10 mo, 18 (49%) pts required transient treatment interruption, 14 due to non-hematologic toxicities, 3 due to hematologic toxicities, and 1 due to both. Sixteen pts (43%) have required dose reductions. The actual median daily dose for all pts was 100 mg; it was 100 mg for pts treated on the QD schedule, and 90 mg for those in the BID schedule. There is no significant difference in grade 3–4 toxicity by treatment schedule. Conclusion: Rapid, complete cytogenetic responses to dasatinib 100 mg/day occur in a high percentage of patients with previously untreated CML-CP. Once daily dosing appears to be associated with less toxicity. Accrual to this trial continues.

598 Background: Prior clinical data suggest a dose-related response to cmab when combined with irinotecan in pts with KRAS WT tumors who do not develop grade 2 and above rash with standard cmab dosing. However, the investigation of higher doses of cmab in the setting of acquired or innate resistance to standard dose cmab has not been previously investigated. We conducted a phase II clinical trial of high-dose cmab plus irinotecan in KRAS WT pts with standard-dose cmab plus irinotecan – refractory disease to address this question. Methods: Pts with KRAS WT MCRC progressing on standard dose of cmab with irinotecan were eligible for study. Pts should have received a minimum of 6 weeks of prior standard dose cmab plus irinotecan and progressed within 4 weeks from the last dose. Cmab was administered at 500 mg/m2/week and irinotecan was administered at the same dose/schedule on which the patient previously progressed. 12-week PFS rate was the primary endpoint. Results: 8 pts were treated on study: median age 68 yrs (45-85), 5 pts were males, ECOG performance status was 1 in all 8 pts. Grade ≥ 3 toxicities consisted of hypomagnesaemia (4 pts), anemia (1 pt), leucopenia (1 pt), fatigue (1 pt), and diarrhea (1 pt). 6 pts achieved stable disease (with regression in target lesions noted in 3 pts). 12 week PFS rate is 5/8 and 18 week PFS is 4/8. 3 pts remain on study at 4.5, 5, and 8 months from enrollment. Conclusions: High-dose cmab/irinotecan is well tolerated except for hypomagnesemia. Encouraging prolonged disease stabilizations warrant further investigation of this approach in pts in KRAS WT population. Accrual is ongoing. [Table: see text]

e16034 Background: Apatinib, a small molecule multi-target tyrosine kinase inhibitor with high selectivity for VEGFR-2, has been approved for the treatment of advanced gastric cancer or gastroesophageal adenocarcinoma in China by significantly improving progression-free survival (PFS) and overall survival (OS). Here, we report safety and efficacy data from an open-label, single-arm, multicenter, phase IV trial of apatinib as a third-line or later line treatment for advanced gastric cancer. Methods: Eligible patients had histologically or cytologically confirmed advanced gastric cancer or gastroesophageal junction adenocarcinoma; and an Eastern Cooperative Oncology Group (ECOG) performance status of 0–2; and adequate haematological and hepatic function; and failure of at least two lines of chemotherapy. Patients received oral apatinib until disease progression, death or unacceptable toxicity. The primary endpoint was safety, and secondary endpoints included PFS and OS. Results: The intention-to-treat population (ITT) included 2004 patients. At baseline, the median age was 59 (range, 19-85) years, ECOG performance status of 0/1/2 (%) was 15.4/68.8/15.1, and stage III/IV was 3.5/96.4; 98.8% had metastases, and among which metastatic foci≤2/ > 2 was 64.5/34.2 (%), respectively. 89.6% of the patients were given apatinib 500mg as the initial does and the median treatment duration was 56 days. After a median follow-up of 126.5 days, adverse events (AEs) occurred in 95.1% of the patients and 70.3% were grade ≥3. 87.9% of the patients experienced treatment-related AEs (TRAEs), of which 51% had grade ≥3, 12.3% and 16.8% reduced dose and discontinued the treatment, respectively. 57 (2.9%) TRAEs-related deaths were reported, mainly because of gastrointestinal bleeding (16 cases), upper gastrointestinal haemorrhage (7), cerebral haemorrhage (2), and gastric perforation (1). The incidence of TRAEs of special interest was 74.3%; 38.1% of patients developed grade≥3, mainly including hypertension (26.3%), bleeding (5.1%), proteinuria (4.5%), and hand-foot syndrome (3.1%). In an ITT population, median PFS was 2.7 months (95%CI 2.23-2.79) and median OS was 5.8 months (95% CI 5.42-6.11). Conclusions: This study confirms that apatinib has a well-established and manageable safety profile and survival benefit as third or later line therapy for patients with advanced gastric cancer or gastroesophageal junction adenocarcinoma. Clinical trial information: NCT02426034.

9000 Background: In the randomized phase 3 CheckMate 9LA trial (NCT03215706), first-line NIVO + IPI combined with 2 cycles of chemo significantly improved overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) vs chemo alone (4 cycles). Clinical benefit was observed regardless of programmed death ligand 1 (PD-L1) expression level and histology. Here we report data with 2 years’ minimum follow-up from this study. Methods: Adult patients (pts) with stage IV / recurrent NSCLC, ECOG performance status ≤ 1, and no known sensitizing EGFR/ALK alterations were stratified by PD-L1 (< 1% vs ≥ 1%), sex, and histology (squamous vs non-squamous) and were randomized 1:1 to NIVO 360 mg Q3W + IPI 1 mg/kg Q6W + chemo (2 cycles; n = 361) or chemo alone (4 cycles; n = 358). Pts with non-squamous NSCLC in the chemo-alone arm could receive pemetrexed maintenance. The primary endpoint was OS. Secondary endpoints included PFS and ORR by blinded independent central review, and efficacy by different PD-L1 levels. Safety was exploratory. Results: At a minimum follow-up of 24.4 months for OS (database lock: Feb 18, 2021), pts treated with NIVO + IPI + chemo continued to derive OS benefit vs chemo, with a median OS of 15.8 months vs 11.0 months, respectively (HR, 0.72 [95% CI, 0.61–0.86]); 2-year OS rates were 38% vs 26%. Median PFS with NIVO + IPI + chemo vs chemo was 6.7 months vs 5.3 months (HR, 0.67 [95% CI, 0.56–0.79]); 8% and 37% of pts who had disease progression received subsequent immunotherapy, respectively. ORR was 38% with NIVO + IPI + chemo vs 25% with chemo. Similar clinical benefit with NIVO + IPI + chemo vs chemo was observed in all randomized pts and across the majority of subgroups, including by PD-L1 expression level (Table) or histology. Any grade and grade 3–4 treatment-related adverse events were reported in 92% and 48% of pts in the NIVO + IPI + chemo arm vs 88% and 38% in the chemo arm, respectively. Conclusion: With 2 years’ minimum follow-up, first-line NIVO + IPI + chemo demonstrated durable survival and benefit versus chemo in pts with advanced NSCLC; no new safety signals were identified.
