7578 Background: BBR 2778 is a novel aza-anthracenedione that shows structural similarities to the anthracyclines, demonstrates single agent activity in patients with NHL, and does not exhibit cardiotoxic effects in animal models. This phase III open-label study was designed to compare the efficacy and tolerability of combination rituximab and BBR 2778, with that of single agent rituximab, in patients (pts) with relapsed or refractory indolent NHL. Methods: Pts were randomly assigned to receive both rituximab and BBR 2778 (experimental arm), or rituximab alone (control arm). In the experimental arm, pts received 375 mg/m2 rituximab IV on days 1 and 8 of cycles 1 and 2 only, and 90 mg/m2 BBR 2778 IV on days 2 and 8 of cycle 1, and on days 1 and 8 of all subsequent cycles. Pts could receive six 21-day cycles of BBR 2778. In the control arm, pts received 375 mg/m2 rituximab IV on days 1, 8 and 15 of cycle 1 and day 1 of cycle 2 only. Disease response was assessed every other cycle according to International Workshop to Standardize Response Criteria for NHL. Toxicities were assessed throughout the study using NCI-CTC criteria. Study was closed early due to poor enrollment. Results: 38 pts (20 experimental, 18 control) were enrolled. Mean age was 66 and 59 years in the experimental and control arm, respectively. Most patients were males and most had ECOG performance status 0 or 1. Efficacy is summarized in the table. Response rate (75 vs 33%) and time to progression (13.2 vs 8.1 months) were better in the BBR 2778 arm. Only pts in the experimental arm had study drug related serious adverse events (2 febrile neutropenia, 1 pneumonia, 1 neutropenia) and adverse events resulting in withdrawal (6 vs 0). Conclusions: Combination of BBR 2778 and rituximab is superior to rituximab alone with regard to time to progression and overall response rate. BBR 2778 combined with rituximab appeared to be a generally well tolerated regimen in patients with relapsed/refractory indolent NHL. [Table: see text] [Table: see text]

e15550 Background: The combination of anti-VEGF or anti-EGFR targeted drugs with chemotherapy is the standard first-line therapy for metastatic colorectal cancer (mCRC), and the followed maintenance treatment is an optional approach to balance the efficacy and toxicity. However, studies regarding the maintenance strategies based on antiangiogenic TKIs are limited currently. Anlotinib, a novel oral multi-target TKI which can inhibit both tumor angiogenesis and tumor cell proliferation simultaneously, substantially prolonged the PFS with manageable toxicity for refractory mCRC in the phase III ALTER0703 clinical trial. Here we report an update on the effectiveness and safety of anlotinib plus XELOX as first-line treatment followed by anlotinib monotherapy for mCRC. Methods: In this open label, single-arm, multicenter phase II clinical trial, 53 mCRC patients without prior systemic treated, aged 18-75 and an ECOG performance status of 0 or 1 were planned to recruit. Eligible patients received capecitabine (1000 mg/m2, po, d1-14, q3w) and oxaliplatin (130 mg/m2, iv, d1, q3w) plus anlotinib (10mg, po, d1̃14, q3w) treatment for 6 cycles. After 6 cycles of inducing therapy, patients would receive anlotinib (12mg, po, d1̃14, q3w) as maintenance therapy until disease progression or intolerable adverse events (AEs). The primary endpoint was PFS; Secondary endpoints included ORR, DCR, DOR and safety. Results: By the data analysis cutoff date of January 22, 2021, a total of 18 patients were enrolled, of which 12 patients were available for efficacy assessment. In best overall response assessment, there were 50.0% PR (6/12), 33.3% SD (4/12) and 16.7% PD (2/12). The ORR was 50.0% (95% CI, 21.1-78.9%) and DCR was 83.3% (95% CI, 51.5-97.9%). The longest duration of treatment was 8.8 months and the response was still ongoing. The median PFS was not reached. The most common treatment related adverse events (TRAEs) of any grade (≥20%) were leukopenia, hypertension, neutropenia, diarrhea, fatigue, hypertriglyceridemia. Grade 3/4 TRAEs included hypertension (22.2%), hypertriglyceridemia (11.1%), lipase elevated (11.1%) and neutropenia (5.6%). No grade 5 AEs occurred. Conclusions: The update results suggested that anlotinib combined with XELOX as first line regimen followed by anlotinib monotherapy showed promising anti-tumor activity and manageable safety for patients with mCRC. And the conclusions needed to be confirmed in trials continued subsequently. Clinical trial information: ChiCTR1900028417.

7637 Background: Impaired performance status in NSCLC is associated with poor prognosis and reduced tolerance for treatment- related toxicities. Current treatment guidelines agree that PS 2 patients with advanced NSCLC benefit from systemic chemotherapy; however, no consensus exists on specific treatment recommendations; i.e., single-agent vs. combination chemotherapy. Methods: Two recent phase III randomized trials in advanced NSCLC (STELLAR 3 and 4) enrolled exclusively PS 2 patients and compared experimental treatment to either standard combination chemotherapy (paclitaxel/carboplatin; P/C), or single agent chemotherapy (vinorelbine or gemcitabine; V or G). An exploratory comparison of the control arms was performed to determine the degree of benefit and amount of added toxicity associated with standard combination vs. single agent chemotherapy. Results: Combination chemotherapy resulted in improved time to progression compared to single agent ( Table ). However, no statistical difference between treatment arms was noted for overall survival and 1-yr survival. Adverse events are listed in the table . Overall, the frequency of serious adverse events was 40% in the combination-arm and 35% in the single agent-arm. When only considering drug-related toxicities, the frequency of serious adverse events was 21% in the combination-arm and 5% in the single agent-arm. Conclusions: PS 2 patients receiving single agent chemotherapy have a similar outcome compared to those receiving combination chemotherapy; serious treatment related toxicities are less frequent with single agent therapy. Based on the currently available evidence, the use of single-agent therapy seems reasonable in PS 2 patients. [Table: see text] [Table: see text]

129 Background: Docetaxel (T) administered at every three weeks is standard treatment for advanced HRPC. We compared 2-weekly to 3-weekly T as first- or second-line chemotherapy of advanced HRPC in this prospective randomized multicenter trial. Methods: 360 pts were randomly allocated to receive T 75 mg/m2 i.v. d1 q3 wks (tT) or 50 mg/m2 i.v. d1 and d 14, q4 wks (bT) from March 2004 to May 2009. Prednisolon 10 mg/day was administered in both groups. The groups were well balanced according to the WHO performance status, mean age (70 vs. 68, range 45–87), and the median serum PSA level at study entry (109 vs. 98 μ g/L, range 11–1,490). The primary endpoint was TTF. Study identifier: NCT00255606 . Results: 158 pts (tT, 79; bT, 79) were included in this preplanned interim safety analysis. 567 and 487 cycles were administered in the tT and bT groups, respectively. The most common grade 3–4 adverse events (expressed as %/cycles) in tT /bT were neutropenia 20%/14%, infection with/without neutropenia 8%/3%, fatigue 3%/ 3%, febrile neutropenia 2%/1%, and bone pain 2%/1%. Serious adverse events occurred more frequently in tT (n=60, 10.6% of cycles) than in bT (n=29, 6.0%, p=0.012). One pt. died from coronary infarction and one was diagnosed with ALL (both in bT group). 30 pts (38%) in bT group and 22 pts (28%) in tT group were receiving treatment at 6 months. (p=0.176). Conclusions: Biweekly T has been better tolerated than the conventional triweekly T with fewer serious adverse events and may be associated with similar efficacy. [Table: see text]

TPS7130 Background: There is an unmet need for safer and more effective therapies for CLL patients who are older/have comorbidites. Ibrutinib, a small molecule inhibitor of BTK, has demonstrated single-agent activity in CLL in the Ph 1b/2 study, PCYC-1102-CA. Treatment-naïve (TN) patients aged >= 65 yrs (n=31) experienced an estimated PFS and OS of 96% at 26 months; ORRs per iwCLL were: 10% CR, 58% PR, and 13% PR with lymphocytosis (Byrd, ASH 2012). AEs were generally Grade 1/2, most commonly diarrhea. Incidence of Grade 3/4 hematologic toxicities was low. These findings support a phase III study of ibrutinib in older patients with treatment-naïve CLL/SLL. Methods: The ongoing study is a randomized, multicenter, open label Ph 3 study comparing safety and efficacy of ibrutinib vs. chlorambucil in TN patients aged >= 65 yrs with CLL/SLL. Approximately 272 patients will be randomized in 1:1 ratio to receive either chlorambucil or ibrutinib, stratified for ECOG PS and Rai stage. Oral chlorambucil will be administered at 0.5 mg/kg on Days 1 and 15 of each 28-day cycle, for up to 12 cycles. Ibrutinib 420 mg q.d. will continue until PD or unacceptable toxicity. Key incl. criteria include age >= 65 yrs, active disease requiring treatment per iwCLL, measurable nodal disease by CT, ECOG performance status 0-2, and adequate organ function (ANC ≥1,000/μL, platelets ≥50,000/μL, creatinine clearance ≥30 mL/min). Key excl. criteria include Richter’s transformation, del(17p13.1) or previous treatment for CLL/SLL. The primary endpoint of the study is PFS, assessed by Independent Review Committee (IRC). Secondary endpoints include ORR, MRD-negative CRs, fatigue by FACIT-F, hematological improvement, safety, and tolerability. Subjects who relapse on PCYC-1115 will be enrolled on PCYC-1116 for long term follow up. Second line therapy is investigator choice; ibrutinib will be made available for patients who experience IRC-confirmed PD ≤12 months of completing chlorambucil therapy, if they meet the treatment criteria. Approximately 85 sites will enroll patients in North America, Europe, Israel, Australia/New Zealand and China. Enrollment began in Q1 2013. Clinical trial information: NCT01722487.

8567 Background: Clinical trial (CT) IMpower133 met both primary endpoints and is the first CT to show significant clinical improvement over standard chemotherapy (C) with a good safety profile in first line (1L) ES-SCLC. The addition of ATZ to CB + ET resulted in an OS landmark of 34% and 22% compared to 21% and 16.8% of patients alive at 18 and 24 months respectively versus C. IMfirst evaluates ATZ + CB or CP + ET in a broader patient population than the pivotal study. ECOG Performance status (PS) 2, asymptomatic untreated brain metastases, underlying stable autoimmune diseases and HIV+ pts are eligible. IMfirst also includes the possibility of 6 C induction cycles according to investigator´s choice and consolidation radiotherapy. Methods: To evaluate the safety and efficacy of ATZ added to CB or CP + ET as 1L treatment in an interventional real world setting of ES-SCLC. Exploratory endpoints include tumor biomarker analysis related to ATZ. Results: As of Oct 2020, 117 pts had been enrolled, 105 treated with ATZ + CB + ET and 12 with ATZ + CP + ET. The median age was 65 years (Y) (range 35-89); 84 males; 14 pts (12%) had CNS metastases and 66 pts were current smokers and 50 former smokers, one had never smoked. The PS was 0 in 28 pts (24%), 1 in 75 (64%) and 2 in 14 (12%). The median of cycles of ATZ received was 4 for all the pts (range 1-12) and 2 for the pts (40) in maintenance phase (range 1-8). Number of pts with adverse events (AEs) was 109, 36 with Serious Adverse Events (SAEs) and 63 with AEs. 8 pts had SAEs related to treatment, 4 had adverse events of special interest and 13 pts discontinued the treatment due to AEs: 6 to ATZ, 12 to CB or CP and 10 to ET, 1 patient discontinued ATZ due to a related AE. Table shows the treatment related AEs (TRAEs). No grade 5 TRAEs were reported. Conclusions: IMfirst induction phase analysis confirms the safety profile of ATZ plus C in a broader population of patients. Efficacy, biomarker and further safety analyses will be presented in the future with longer follow up.[Table: see text]

Purpose We hypothesized that the addition of gefitinib, an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, to docetaxel would enhance therapeutic efficacy in squamous cell carcinoma of the head and neck (SCCHN). Patients and Methods Patients with recurrent or metastatic SCCHN with Eastern Cooperative Oncology Group (ECOG) performance status of 2, or patients with ECOG performance status of 0 to 2 but were previously treated with chemotherapy, were randomly assigned to receive weekly docetaxel plus either placebo (arm A) or gefitinib 250 mg/d, orally (arm B) until disease progression. At the time of progression, patients in the placebo arm could receive single-agent gefitinib. EGFR, c-MET, and KRAS mutations and polymorphisms in drug metabolizing enzymes and transporters were evaluated by pyrosequencing. Results Two hundred seventy patients were enrolled before the study was closed early at interim analysis (arm A, n = 136; arm B, n = 134). Median overall survival was 6.0 months in arm A versus 7.3 months in arm B (hazard ratio, 0.93; 95% CI, 0.72 to 1.21; P = .60). An unplanned subset analysis showed that gefitinib improved survival in patients younger than 65 years (median 7.6 v 5.2 months; P = .04). Also, there was a trend for improved survival in patients with c-MET wild-type (5.7 v 3.6 months; P = .09) regardless of treatment. Grade 3/4 toxicities were comparable between the two arms except that grade 3/4 diarrhea was more common with docetaxel/gefitinib. Of 18 eligible patients who received gefitinib after disease progression in arm A, one patient had a partial response. Conclusion The addition of gefitinib to docetaxel was well tolerated but did not improve outcomes in poor prognosis but otherwise unselected patients with SCCHN.

15050 Background: Paclitaxel (PTX) and 5’-DFUR have single-agent activity in gastric cancer and have distinct mechanisms of action and no overlap of key toxicities. Synergistic interaction between PTX and 5’-DFUR is mediated by taxane-induced up-regulation of thymidine phosphorylase, which converts 5’-DFUR to 5-FU. We conducted a combination phase II study of PTX and 5’-DFUR in patients with unresectable or recurrent gastric cancer to evaluate the efficacy and safety in an outpatient. Methods: Eligibility criteria included patients with histologically proven unresectable or recurrent gastric cancer who had measurable lesions fitting RECIST, up to one prior chemotherapy, a performance status of 0–2 and adequate organ function. According to our results of phase I study (Proc ASCO 2004, Abstr. 4228), the treatment included PTX 70 mg/m2 i.v. on days 1, 8, and 15 every 4 weeks and 5’-DFUR 600 mg/body p.o. everyday until there was disease progression or the appearance of unacceptable toxicity. Primary endpoint was: RR; and secondary endpoints were OS, PFS, TTF and onset rate of adverse events. Results: Between June 2004 and July 2006, 42 patients were enrolled in this study: including 34 men; 8 women; median age of 70 years (range, 44–85 years); and PS levels were, zero with 27, one with 13 and two with 2 patients. In 42 eligible patients, clinical usefulness was evaluated resulting in response rate of 40.5% (CR, 1; PR, 16; SD, 17; PD, 6; and NE, 2 patients). The first-line therapy involved 28 patients in whom the response rate was 50.0%. The second-line therapy involved 13 patients (all TS-1 failure) in whom the response rate was 23.1%. OS was 371 days, PFS was 170 days and TTF was 147 days. All patients were treated in outpatient. Severe adverse events were found in 2 patients to discontinue the present treatment, though other adverse events were relatively mild without death due to the present therapy. Commonly observed grade 3/4 adverse events were neutropenia (26.2%), appetite loss (4.8%), neuropathy (4.8%), and fatigue (4.8%). Conclusions: The outpatient combination of a weekly PTX and 5’-DFUR chemotherapy is active and well tolerated. No significant financial relationships to disclose.

1003 Background: Single-agent DOC is commonly used to treat MBC. Axitinib (AG) is a potent TKI of VEGFRs. A phase I lead-in study identified 80 mg/m2 q3wks of DOC in combination with 5 mg BID of AG as the recommended phase 2 dose. The primary objective was to determine whether the time to progression (TTP) of AG+DOC arm is superior to DOC+PL. Methods: Pts with no prior chemotherapy for MBC and =12 mos from adjuvant chemotherapy (aCT), measurable disease, ECOG performance status (PS) of 0–2, and no uncontrolled brain metastases were randomly assigned (2:1) to receive treatment with either DOC+AG or DOC+PL without prophylactic growth factor in cycle 1. Tumor measurements were performed q9wks. Pts were stratified according to estrogen receptor (ER) status, prior aCT and PS (0–1 or 2). Results: A total of 168 pts were randomized. 92 pts had received prior aCT, 27 of whom received a prior taxane. Treatment arms were well balanced for prior adjuvant and taxane therapy. A median of 7 cycles of AG+DOC (range: 1–18) and 7 cycles of DOC+PL (range: 1–23) were administered. The most common non-hematologic adverse events observed in the AG+DOC arm included diarrhea (60%), nausea (53%), alopecia (51%), fatigue (49%), stomatitis (44%) and vomiting (40%). Grade 3/4 adverse events that were increased with AG+DOC vs DOC included febrile neutropenia (16 vs 7%), fatigue (13 vs 5%), stomatitis (13 vs 2%), diarrhea (11 vs 0%) and hypertension (5 vs 2%). Other grade 3/4 hematologic toxicities were similar in both arms. The median TTP (by RECIST) was 8.2 mo with AG+DOC arm and 7 mo with DOC+PL arm with a hazard ratio of 0.73 (prespecified, one-sided p=0.052). The overall response rate (ORR) was 40% for AG+DOC arm and 23% for DOC+PL arm (p=0.038). In a hypothesis-generating subgroup analysis, the median TTP in patients receiving prior aCT was 9.0 mo with AG+DOC arm and 6.3 mo with DOC+PL arm with a hazard ratio of 0.54 (p=0.012). Within this stratum, ORR was 45% for AG+DOC arm and 13% for DOC+PL arm (p=0.003). Conclusions: The anti-angiogenic TKI AG combined with DOC (80 mg/m2 q3wks) as first line therapy for MBC has an acceptable safety profile and promising anti-tumor activity. No significant financial relationships to disclose.

4000 Background: Cetuximab in combination with irinotecan-based regimens has proven activity in previously-treated patients (pts) with mCRC. The present trial investigated the effectiveness of cetuximab in combination with standard FOLFIRI compared with FOLFIRI alone in the first-line treatment of pts with epidermal growth factor receptor (EGFR)-expressing mCRC. Methods: Pts were randomized 1:1 to receive either cetuximab (400 mg/m2 initial dose then 250 mg/m2/week [w]) plus FOLFIRI q 2 w (irinotecan 180 mg/m2, FA 400 mg/m2, 5-FU bolus 400 mg/m2, 5-FU infusion 2,400 mg/m2 over 46 hours) (Group A) or FOLFIRI alone (Group B). The primary endpoint was progression-free survival (PFS), with secondary endpoints of overall survival (OS), response rate (RR), disease control rate and safety. 633 events were required to statistically differentiate PFS between groups with 80% power. Results: Between August 2004 and October 2005, 1,217 pts were randomized, 608 to Group A and 609 to Group B (60% male, median age 61 [19–84], ECOG performance status: 0=54%; 1=43.5%; 2=3.5%). Median PFS was significantly longer for Group A compared to Group B (8,9 months [8 - 9,5] for Group A vs. 8 months [7.6 - 9] for Group B, p=0.036). Response Rate was also significantly increased by cetuximab (46.9% vs. 38.7%, p=0.005). Treatment was generally well tolerated with neutropenia (26.7% Group A, 23.3% Group B), diarrhea (15.2% and 10.5% respectively) and skin reactions (18.7% and 0.2% respectively) being the most common grade 3/4 adverse events. Conclusions: Cetuximab in combination with FOLFIRI significantly increases response rate and significantly prolongs PFS in the first-line treatment of pts with mCRC, reducing the relative risk of progression by approximately 15%. Treatment-related side effects of cetuximab in combination with FOLFIRI were as expected, with diarrhea being moderately and skin reactions significantly more frequent as compared to FOLFIRI alone.

8561 Background: Pralatrexate is a novel targeted antifolate designed to accumulate preferentially in cancer cells. PROPEL, a pivotal phase 2, non-randomized, open-label, international study, is the largest prospective study in patients (pts) with relapsed or refractory PTCL. Methods: Pts received 30 mg/m2 of pralatrexate intravenously weekly for 6 of 7 weeks, supplemented with B12 and folic acid. Primary endpoint = objective response rate (ORR); secondary endpoints = response duration, progression-free survival, and overall survival. Eligibility criteria: histologically confirmed PTCL, disease progression after ≥ 1 prior treatment, and ECOG performance status ≤ 2. Pathology was confirmed by independent central review, response to therapy was assessed by independent central review using International Workshop Criteria (IWC). Results: 115 pts were enrolled, 109 were evaluable for efficacy. 111 treated pts included 76 males (68%) and 35 females (32%). Pts had failed a median of 3 prior regimens and thus were heavily pre-treated. 78 pts (70%) failed CHOP, 18 (16%) had previous autologous stem cell transplant. 25% of pts never responded to any prior therapy; 53% did not respond to last prior therapy. The majority (59 pts, 53%) had PTCL not-otherwise specified. The ORR by central review was 27% (n = 29). 11 pts (10% overall, 38% of responders) had a complete response (CR), 18 pts (17%) had a partial response (PR), and 23 (21%) had stable disease. ORR by investigators assessment was 39% (n = 42). The median duration of response cannot be accurately estimated at this time, though responses of > 1 year have been observed. 69% of responses were after just 1 cycle. 5 responding pts went on to transplant. The most frequent Grade (Gr) 3–4 adverse events were mucosal inflammation (Gr 3 = 17%, Gr 4 = 4%) and thrombocytopenia (Gr 3 = 14%, Gr 4 = 19%). Conclusions: The results of PROPEL show that pralatrexate exhibits substantial activity in pts with relapsed or refractory PTCL, as assessed by a rigorous central review, with durable CRs /PRs, irrespective of the amount of prior therapy.
