German Multicenter Trial

4003 Background: Two randomized trials (GERCOR/GISCAD: gemcitabine [GEM] plus oxaliplatin versus Gem; German multicenter trial: Gem plus cisplatin versus Gem) indicated superior efficacy in terms of response rate and progression-free survival (PFS) for combined therapy. While a trend for prolonged overall survival (OS) was reported in these underpowered studies, they failed to demonstrate a significant advantage. Methods: We report a pooled analysis of both studies. Standard methods for meta-analysis based on individual patient (pt) data were used. Results: Among 503 evaluable pts, 252 received the combination therapy (GP), while 251 pts were treated with Gem single agent (G). In the GP vs G groups, an ECOG performance status = 0 was observed in 40% vs 35%, distant metastasis in 72% vs 73%, and pathological tumor grading of 3 in 34% vs 38%, respectively. A high degree of homogeneity was noted among the study groups with regard to survival data. For PFS, the pooled univariate analysis indicated a hazard ratio (HR) of 1.34 (95% CI, 1.11–1.63, p=.0030; median PFS 5.5 m vs 3.5 m) in favour of the GP-combination. The benefit of the GP-combination was greatest in the subgroup of pts with PS 0 (HR=1.56; 95% CI, 1.11–2.20, p=.013). OS was significantly superior in the GP pts (HR=1.23; 95% CI, 1.02–1.49, p=.031; median OS 8.3 m vs 6.7m). Again, pts with a PS=0 may have a greater benefit from treatment intensification (HR=1.38; 95% CI, 0.99–1.93, p=.063). Conclusions: This pooled data analysis indicates that combination of gemcitabine with a platinum analog such as oxaliplatin or cisplatin significantly improves PFS and OS as compared to single-agent gemcitabine in APC.

e18004 Background: Anti-PD1 checkpoint inhibitors (ICI) represent an established standard of care for patients with recurrent/metastatic head & neck squamous cell carcinoma (RMHNSCC). Landmark studies excluded patients with ECOG performance status (PS) ≥ 2; the benefit of ICI in this population is therefore unknown. Methods: We retrospectively reviewed RMHNSCC patients who received at least 1 dose of ICI at our institution. Demographic data and clinical outcomes were obtained; the latter included objective response to ICI (ORR), physician-documented CTCAE grade 2+ toxicity (irAE), and any unplanned hospitalization within 100-days of last ICI dose (UH). Associations between demographic data and clinical outcomes were explored using both uni- and multivariate analysis. Overall survival (OS) was estimated using a Cox proportional hazards model; ORR, irAE, and UH were evaluated with logistic regression. This project was approved by our institutional IRB. Results: We identified 152 RMHNSCC patients who were treated with ICI between 1/2013 and 1/2019. ECOG PS was 0 in 42 (27%), 1 in 75 (50%), 2 in 27 (18%), 3 in 2 (1%), and unknown in 6 (4%) patients. The median age was 61 (range: 25 - 90). 124 (82%) were male, 124 (82%) were white, and 69 (45%) were never-smokers. The most common primary sites were the oropharynx (n = 59, 40%), oral cavity (n = 39, 26%), nasopharynx (n = 11, 7%), and larynx (n = 10, 6%). 54 (36%) were p16+ oropharynx cancers. CPS score was available in 10 (6.6%). Single agent ICI was received by 118 (77%) patients. 66 (44%) had a documented irAE and 54 (36%) had an UH. A multivariate model for OS containing PS, smoking status and HPV status showed a strong association between inferior OS and ECOG 2/3 compared to 0/1 (p < 0.001; HR = 3.30, CI = 2.01-5.41), as well as former (vs. never) smoking status (p < 0.001; HR = 2.17, CI = 1.41-3.35). Current smoking (p = 0.25) did not reach statistical significance. On univariate analysis, poor PS was associated with inferior ORR (p = 0.03; OR = 0.25, CI = 0.06-0.77) and increased UH (p = 0.04; OR = 2.43, CI = 1.05—5.71). There was no significant association between irAE and any patient characteristic. Conclusions: We observed inferior overall survival among ICI-treated RMHNSCC patients with ECOG 2/3 in our single-institution, retrospective series. Our findings help frame discussion of therapeutic options in this poor-risk population. Further study must be done to determine which interventions are of greatest benefit for RMHNSCC patients with declining performance status.

The Impact

9559 Background: In randomized trials, ASCT improves survival in MM patients (pts) < age 65. The impact of ASCT on survival in older adults with MM is unknown. Methods: In a retrospective cohort study, all pts ≥ age 65 with MM diagnosed between 2000 and 2010 were identified from the Barnes-Jewish Hospital Oncology Data Services Registry (N=199), including demographic, comorbidity (ACE-27 index) and survival data. Medical records were reviewed for stage, ECOG Performance Status (PS) and treatment. Pts > age 77 or who received only steroids/supportive care were excluded (N=53). The primary endpoint was overall survival (OS), defined as time from diagnosis to death, censored at last follow-up. Univariate analyses for factors associated with undergoing ASCT were performed using Fisher’s exact test or nonparametric rank-sum test; multivariate logistic regression was used to create propensity scores for ASCT. The association between ASCT and OS was assessed using a multivariate Cox proportional hazard model with propensity scores adjustment; missing values in predictors were imputed using multiple imputations. Results: Of 146 pts included, the median age was 68 (range 65-77); 53% were male, 81% Caucasian; 43% underwent ASCT. Comorbidities were common (43.9% mild, 21.6% moderate and 9.3% severe). Durie-Salmon Stages were I – 9.5%, II-18.1%, III-72.4%. PS at diagnosis was 0 - 18.3%, 1 - 51.0%, 2 - 21.2% and 3 - 9.6%. Most received novel agents (thalidomide, lenalidomide or bortezomib) in their initial treatment (25.2% alkylators only, 58.6% novel single agents ± steroids, 16.2% novel combination regimens). Age (p<0.0001) and insurance/payer (p=0.02) were associated with ASCT. On univariate analysis, ASCT [Hazard Ratio (HR) 0.54 (95% confidence intervals (CI) 0.35-0.82)] and PS [PS 1: HR 2.3 (CI 1.0-4.9), PS2: HR 3.3 (1.4-7.9); PS 3: HR 3.5 (CI 1.3-9.3)] were associated with mortality. On multivariate analysis controlling for PS, comorbidity, stage and propensity to undergo ASCT, ASCT was associated with reduced mortality [HR 0.52 (CI 0.30-0.92), p=0.02]. Conclusions: In pts over age 65 with MM, ASCT is associated with better OS after adjusting for propensity to undergo ASCT.

e17506 Background: The anti-PD1/-PDL1 ICmABs can result in objective responses in some (13-20%) patients (pts) with HNSCC. We evaluated clinical factors that may predict oncologic outcomes. Methods: We identified pts who received an ICmAB at our institution and retrospectively collected demographic, tumor, treatment, progression, and survival data. The Kaplan Meier method was used to estimate survival. Log-rank and Wilcoxon tests were used to explore associations between clinical features and outcomes. Results: 55 pts received ICmAB in a clinical trial at our center from 8/2012 to 12/2016. The median age was 64 years, 13 (24%) were female, and 45 (82%) were white. ECOG Performance Status (PS) was 0 and 1 in 23 (42%) and 32 (58%) pts, respectively. 29 (53%) were current/former smokers who smoked a median of 20 (range 0-70) pack years. Primary sites included: oropharynx (OP) 31 (56%), oral cavity 9 (16%), nasopharynx 6 (11%), nasal cavity 3 (5%), hypopharynx (HP) 2 (4%), unknown (UK) 2 (4%), and skin 2 (4%). 28 (51%) were p16+, with the following primary sites: OP in 26, UK in 1, and HP in 1. 53 (96%) received prior curative intent therapy. A median of 2 (range 0-5) lines of systemic therapy (including curative intent) were given prior to ICmAB initiation, and 31 received an ICmAB as a single agent. There were 19 (35%) objective responses with 1 complete response, and 14 (25%) had stable disease. With a median follow-up of 12 months (m), the median overall survival (OS) was 15m (95% CI 11,47), and median time to progression was 4m (95% CI 2.2, 6.8). An ECOG PS of 0 vs 1 was associated with superior OS (36m vs 11m p = 0.001). Tobacco use, p16+ disease, single agent ICmAB vs. combination, number of lines of prior systemic therapy, or radiation therapy within 3m prior to ICmAB initiation did not appear to have a relationship with survival. Conclusions: A PS of 0 predicted for more favorable OS among HNSCC pts receiving ICmAB in this single center retrospective cohort. In contrast to data with chemotherapy, established prognostic markers (including p16+ and limited/no tobacco use) did not appear to impact survival.

PurposeThis phase III trial compared the efficacy and safety of gemcitabine (Gem) plus capecitabine (GemCap) versus single-agent Gem in advanced/metastatic pancreatic cancer.Patients and MethodsPatients were randomly assigned to receive GemCap (oral capecitabine 650 mg/m2twice daily on days 1 to 14 plus Gem 1,000 mg/m2by 30-minute infusion on days 1 and 8 every 3 weeks) or Gem (1,000 mg/m2by 30-minute infusion weekly for 7 weeks, followed by a 1-week break, and then weekly for 3 weeks every 4 weeks). Patients were stratified according to center, Karnofsky performance score (KPS), presence of pain, and disease extent.ResultsA total of 319 patients were enrolled between June 2001 and June 2004. Median overall survival (OS) time, the primary end point, was 8.4 and 7.2 months in the GemCap and Gem arms, respectively (P = .234). Post hoc analysis in patients with good KPS (score of 90 to 100) showed a significant prolongation of median OS time in the GemCap arm compared with the Gem arm (10.1 v 7.4 months, respectively; P = .014). The overall frequency of grade 3 or 4 adverse events was similar in each arm. Neutropenia was the most frequent grade 3 or 4 adverse event in both arms.ConclusionGemCap failed to improve OS at a statistically significant level compared with standard Gem treatment. The safety of GemCap and Gem was similar. In the subgroup of patients with good performance status, median OS was improved significantly. GemCap is a practical regimen that may be considered as an alternative to single-agent Gem for the treatment of advanced/metastatic pancreatic cancer patients with a good performance status.

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.

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.

17111 Background: Bevacizumab is a novel antiangiogenic agent that has been shown to improve response rates and survival of patients with advanced non-squamous NSCLC when added to paclitaxel and carboplatin. Pemetrexed is a multitargeted antimetabolite that has shown activity in NSCLC as a single agent and when combined with carboplatin. Because the combination of pemetrexed and carboplatin has activity comparable to that of other standard platinum doublets and promising toxicity profile (Zinner, 2005), the addition of bevacizumab to this regimen is investigated. Methods: This single cohort, phase 2 study evaluates the safety and efficacy of the combination of pemetrexed and carboplatin plus bevacizumab in patients with untreated non-squamous NSCLC. Eligibility requires ECOG performance status 0–1, Stage IIIB (malignant effusion) or Stage IV non- squamous NSCLC, no evidence of CNS metastases, no anticoagulation. Treatment consists of pemetrexed 500 mg/m2 over 10 minutes, carboplatin AUC 6 over 30 minutes, and bevacizumab 15 mg/kg over 30–90 minutes. Treatment is repeated every 21 days for 6 cycles. For patients who have either stable disease or partial response, pemetrexed 500 mg/m2 and bevacizumab 15 mg/kg are continued every 21 days until progression of disease or toxicity. All patients receive folic acid, vitamin B12 and steroid prophylaxis. Tumor response is assessed using RECIST every 2 cycles during treatment with carboplatin and then every 3 cycles during treatment with pemetrexed and bevacizumab alone. Results: From 8/2005 to 12/2005, 10 (of planned 50) patients with Stage IIIB and IV non-squamous NSCLC have been enrolled and treated. Patient characteristics are: median age: 65 (48–71), 20% female, 80% male, 30% stage IIIB, 70% stage IV. Median number of cycles delivered is 5 (range 1–9). No patient has discontinued therapy secondary to progressive disease or toxicity to date. 6 patients are evaluable for response: 1 PR, 1 minor response (24% reduction), 4 SD. No grade 3/4 toxicities have been experienced. Conclusions: This is a highly tolerable and active regimen with little toxicity to date. Updated response and toxicity data will be forthcoming.

13134 Background: Perifosine is a novel alkylphospholipid that has been shown to affect multiple signal transduction pathways including Akt, MAPK and JNK (Kondapaka, Mol. Canc. Ther 2: 1093–1103. 2003). Treatment with a taxane initially activates Akt, and persistent activation increases resistance to the drug (Vanderweele, Mol. Canc. Ther. 3: 1605–13, 2004). Methods: Twelve patients (pts) were enrolled on this study. T was given at a dose of 175 mg/m2 on day 8 (after 7 days of perifosine) of a 21 day cycle; this was to obtain a steady state level of P at the tumor before exposure to T. The intent of the protocol was to determine if full dose P could be delivered with 50 mg of perifosine given orally 1, 2 or 3 times a day on days 1–14 of each cycle. Results: Disease sites included lung 3, thyroid 3, breast 1, esophagus 1 and other 4, Median age was 66 (range 45 - 83); 6 pts were male and median ECOG performance status was 1 (range 0–2). All pts had received prior chemotherapy (median 2 regimens); 3 had prior treatment with a taxane. Three pts were entered at each dose level and the cohort expanded to 6 pts if 2 or more pts experienced a grade 3/4 non-hematologic toxicity (DLT) during cycle 1. A dose level was toxic if 4 or more pts experienced a DLT during cycle 1. A total of 30 cycles and a median of 2 cycles (range 1–11) per patient were delivered. There were no grade 3/4 hematologic toxicities. Full dose T was given in all treatment cycles. P dose reductions were required in 6% of cycles (50 mg - 7%, 100 mg - 0%, 150 mg - 7%). One patient missed one dose due to nausea and one pt was stopped due to diarrhea. The grade 3 toxicities for each cohort are given in the table below. The elevated glucose value was 321. Nine pts were evaluable for response; two pts with thyroid cancer had stable disease by the RECIST criteria for 9 and 10+ months. Conclusions: In this study the usual single agent doses of P (150 mg daily) & T (175 mg/m2 q 3 weeks) were given together without increasing the toxicities that would be expected from using each drug alone. Phase II studies are warranted to define activity of the combination. [Table: see text] [Table: see text]

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.

8580 Background: The utility of BCT for M remains controversial. A prospective phase II study was conducted to assess the clinical benefit of BCT in patients with stage IV M. Methods: Between March 2005 and March 2006 11 pts (6 Male and 5 Female with a median age of 54 (range 36 - 82)) with metastatic M were treated with paclitaxel 225 mg/m2 via continuous 24 hour IV infusion every 3 wks for 4 cycles or maximum benefit followed by HD IL2, 1.33 mg/m2 every 8 hours for 5 days of wk1 and wk3 based on pts tolerance to a maximum of 12 doses per wk. 2 Male pts received IL2 followed by paclitaxel. Pts had a ECOG performance status of 0 - 2, with a median time of 60 months since diagnosis of disease (range 7 to 240 months). 11 pts (92%) had multiple metastatic sites (50% had lung mets, 58% had liver mets) and 4 pts (33%) had prior chemotherapy or immunotherapy. Results: Of the 13 assessable pts one achieved a PR after paclitaxel and CR after IL2 continuing at 20+ months. One had SD for 1 year after receiving HD IL2 and SD for 6 months while on paclitaxel independently, One had PR for 6 months on paclitaxel and one had MR with paclitaxel for 3 months. 9 pts (69%) had PD on paclitaxel and again on IL2, with a median survival from treatment of 7 months, 2 of these got no IL2 due to rapid PD. An overall response rate of 30% (1 CR on paclitaxel + IL2 , 1 PR on paclitaxel, 2 SD (including MR) on paclitaxel) was seen with a median survival from treatment of 15 months. Conclusions: In this study there may be prolonged survival among responders, which may be due to synergy of sequential BCT, or may reflect single agent activity of each drug. BCT should still be considered as an experimental therapy and further evaluated. No significant financial relationships to disclose.
