7128 Background: Pemetrexed (P), a multi-targeted antifolate, is synergisitic with gemcitabine (G) in preclinical models. A phase I study examining a biweekly schedule established a recommended phase 2 dose of G 1500 mg/m2 followed by P 500mg/m2. Methods: Patients with Stage IIIB (with pleural effusion) or IV NSCLC, ECOG PS of 0 or 1, no prior systemic chemotherapy, immunotherapy, or biological therapy were enrolled. G was infused over 30 minutes, followed immediately by P given intravenously over 10 minutes once on day 1 every 14 days. Cycles were repeated until 12 treatments or progressive disease. All patients received folic acid, vitamin B12 and steroid prophylaxis. Results: Data on 53 patients (29 male, 24 female) are currently available. Median age: 64 (range: 35, 80), ECOG performance status 0:1 = 38%:60%, Stage IIIB:IV = 19%:81%. Three hundred twelve cycles of treatment were administered with 14 dose reductions (26.4%); median number of doses was 5 for both G and P, and median dose intensity was 98.05% for both G and P. Response data included 1 complete response (1.9%), 14 partial responses (26.4%), 24 stable diseases (45.3%), and 10 progressive diseases (18.9%), with a response rate of 28.3% (95% CI: 16.8–42.3%). Patient-based Grade 3/4 hematologic events included febrile neutropenia (9.4%), neutropenia (28.3%), and thrombocytopenia (1.9%). Grade 3/4 non-hematologic events included fatigue (22.6%), dyspnea (7.5%), dehydration (7.5%), diarrhea (5.7%), constipation (3.8%), and pneumonia (1.9%). Preliminary median survival was 7.8 months (95% CI: 6.0–10.8) with 43.4% patients censored and median TTPD was 4.6 months (95% CI: 2.8–6.1). Conclusion: Biweekly G and P appear to be well tolerated in advanced NSCLC. A clinical benefit rate (ORR + SD) of 73.6% indicates activity in patients with advanced NSCLC. The dose intensity for biweekly G and P is higher than a previously reported 6-cycle, 21-day regimen with median dose intensity of 83.2% for P and 82.2% for G (West, et al. Proc ASCO 2005; 7117).

14076 Background: Chemotherapy remains the main treatment option for metastatic oesopagogastric cancer (MOC) patients (Pts). First-line regimens have proved a slight but significant increase in quality of life and survival, but a standard regimen has not been defined yet. Several new drugs, as Docetaxel (D), Oxaliplatin (O) and Capecitabine (C) have demostrated activity in MOC. They have shown synergy in preclinical models and activity in previous phase II trials. The purpose of our study is to asses activity and feasibility of the combination of D, O and C as first-line chemotherapy in MOC patients. Methods: MOC patients, with good ECOG performance status and chemonaive are eligible. Pts receive D 60 mg/m2 day 1, O 85 mg/m2 day 1 and oral C 650mg/m2 bid d1–14 every 3 weeks. Primary endpoints are response according to WHO criteria and toxiciy assesment according to NCI.CTCAE v3.0. Results: From November 2004 to December 2005, 17 Pts have been enrolled. Median ECOG PS is 1 (0–2) M/F:9/8. Median age is 57 years (38–68) Primary tumor are gastric carcinomas (82%) and lower oesofagus carcinomas (18%). Metastatic sites included peritoneum 58%, liver 23% and lung 23%. Median number of cycles is 5 (1–7) Treatment is well tolerated with no toxic deaths. NCI grade 3–4 toxicities include 2 Pts (11.8%) with grade 4 neutropenia and one of them developed septic shock; 2 Pts with grade 3 asthenia, 1 Pt with grade 3 vomiting and 1 patient with grade 3 neurotoxicity. Main NCI grade 2 toxicities are dhiarrea (35.3%) and neurotoxicity (23.5%). 13 Pts have been evaluated for response until now: 9 Pts have a confirmed Partial Response (69.2%) and 2 of them underwent salvage surgery; 3 Pts have Stabilized Disease and 1 Pt Progression Disease. Median time to progression and median overall survival have not been reached yet and the study is still ongoing. Conclusions: The combination of D, O and C at the dosses and schedule used in this trial is effective in MOC with a manageable toxicity profile No significant financial relationships to disclose.

5046 Background: AA is a potent inhibitor of the enzyme CYP17, a major contributor to androgen biosynthesis. Keto is also known to inhibit this enzyme but AA is many-fold stronger in its action. 33 pts with progressive metastatic disease, normal organ function, ECOG performance status (PS) 0–1, and no prior chemo were enrolled. Pts with prior keto treatment were excluded. AA (1000 mg qd) plus prednisone (5mg bid) were administered orally in 28 day cycles. Methods: Results: At baseline median age was 71.0 (range 52–85) yrs and median PSA was 24.7 (range 7.1–1110.0) ng/mL;19/26 pts (73%) had an ECOG PS of 0 and 7/26 (27%) had PS of 1; the median number of prior hormonal therapies was 2; all pts were on LHRHa and 73% of pts had received anti-androgen, all of whom had undergone prior anti-androgen withdrawal. Pts were evaluated at each cycle for PSA response according to PSAWG criteria. 27 pts have available data for PSA response. Total maximal PSA declines of ≥30%, ≥50%, ≥90% were observed in 89% (24/27), 85% (23/27) and 41% (11/27) pts, respectively. Week 12 PSA declines displayed a similar and sustained trend: ≥30%, ≥50% and ≥90% PSA decline in 82%, 78%, and 26% of pts. Post-treatment ECOG PS score was 0 in 24 (92%) pts: 19% experienced improvement in PS (PS 1 to 0 in 5 pts) and 19/19 pts maintained a PS of 0; Median time to PSA progression has not been reached. Majority of adverse events were grades 1–2. Incidence of hypokalemia - 12%; HTN - 6%; edema - 15%. One pt experienced a grade 3 drug-related HTN. Conclusions: Abiraterone acetate plus prednisone has significant anti-cancer activity in patients with metastatic CRPC not previously treated with ketoconazole or chemotherapy, as demonstrated by declines in PSA and improvement in performance status, and is well-tolerated.

e18505 Background: DLBCL occurs frequently in elderly pts and recent studies demonstrated that immunochemotherapy with R-mini-CHOP could be a safe and effective treatment for selected pts over 80 years Methods: Since 2008, R-mini-CHOP has been the treatment proposed for elderly pts with DLBCL referred to our oncogeriatric unit, irrespectively of their performance status (PS). We reviewed data of elderly pts treated for DLBCL at our institution from January 2008 to June 2011. Results: 74 pts (50 women, 24 men) were treated for DLBCL. Median age was 85 years (range 71–97), 84 % of pts ≥ 80 years and 16 % of pts ≥ 90 years. 68 pts (92%) had at least one comorbidity. Median number of daily medicines was 4 (range 0 – 12), irrespectively of treatments for DLBCL. Malnutrition was diagnosed in 49 pts. 50 pts (67,5 %) had a poor PS (> 2). Age-adjusted International Pronostic Index (aaIPI) was 0-1 in 9 pts, 2 in 28 pts and 3 in 35 pts. 61 pts were treated with mini-CHOP (cyclophosphamide: 400 mg/m2 D1; doxorubicine: 25 mg/m2 D1; vincristine: 1 mg total dose D1 and prednisolone 40 mg/m2 by oral route from D1 to D5) plus rituximab (375 mg/m2 D1) every 21 days for 6 cycles. Doxorubicine was replaced by etoposide (150 mg/m2 D1) for 5 pts because of cardiac dysfunction. 8 pts received reduced dose intensity chemotherapy ( without doxorubicine) for the 2 first cycles because of high risk toxicity. Prophylaxis of neutropenia with GCSF was systematic. Median survival was 11 months. 21 pts died during treatment, because of progressive disease (13) or treatment toxicity (6). Complete response (CR) was observed in 44 pts (59,5 %). With a median follow-up of 18 months, 11 relapses were observed. In our population study, aaIPI appears highly predictive of CR, with a CR Rate of 87,5 %, 75 % and 43% respectively for pts with aaIPI 0 - 1, 2 and 3.Hematological toxicity was the most common side effect. Grade 3–4 neutropenia was observed in 28% of the pts and grade 3–4 thrombocytopenia in 12%. 14 pts (19%) experienced at least one episode of febrile neutropenia. Conclusions: In unselected elderly pts with DLBCL, immunochemotherapy with R-mini-CHOP can be effective, but with significant toxicity, even using systematic G-CSF prophylaxis. Prognosis remains poor for pts with aaIPI 3

321 Background: Patients (pts) with UC and creatinine clearance (CrCl) < 60 ml/min are considered cisplatin-ineligible. Since the safety of cisplatin use in patients with CrCl < 60 has not been comprehensively studied, we conducted a retrospective study in this population. Methods: Data were requested and retrospectively collected from 5 collaborating institutions. All patients had stage 2 or higher UC and CrCl < 60. Patient characteristics including age, sex, indication for chemotherapy (neoadjuvant, adjuvant or metastatic disease), schedule, total dose of cisplatin, adverse effects, renal function, blood cell counts and radiologic tumor response were collected. Descriptive statistics were employed with no baseline assumptions. Results: 104 patients were evaluable with a mean age of 63.7+ 8.1 yrs (range 41-77yrs) and 63.5% (n=66) were men. Mean CrCl by Cockroft-Gault formula was 50.8 + 8.0 ml/min (range 26-59 ml/min). Baseline ECOG performance status was 0 in 71.8% (n=74); 1 in 20.3% (n=21) and 2 in 7.8% (n=8) of patients. 40.4% (n=42) received chemotherapy for metastatic disease and the rest received perioperative chemotherapy. Of the patients with metastatic disease, 7.1% patient had complete response (CR), 40.5 % patients had partial response. Mean total dose of cisplatin used in all patients was 414.32±198.01 mg, with 81.7% (n=85) patients receiving ≥70mg/m2 dose per cycle. Percentage of patients with any toxicity with baseline CrCl <45 and >45 were 43.5% and 39.5%, respectively (p=0.81). Neutropenic infection occurred in 16.3% and thrombocytopenic bleed in 8.6%. Grade 3 renal toxicity was seen in only one patient (0.96%) and no toxic deaths were reported. Conclusions: This retrospective clinical experience in pts with UC with CrCl <60 ml/min and mostly ECOG-PS 0-1 suggests that cisplatin-based chemotherapy is feasible and warrants exploration given CRs induced in metastatic disease. Incorporation of prophylactic growth factors and modified schedules may mitigate myelosuppression.

12024 Background: Carboplatin (CBDCA) and gemcitabine (GEM) in combination is used commonly in lung cancer and is administered on a 21 day cycle. The purpose of this study was to determine the maximum tolerated dose (MTD) of CBDCA and GEM administered on a biweekly schedule and to assess safety and efficacy of this schedule. Methods: GEM was given intravenously (IV) over 30 minutes followed by CBDCA also given IV over 30 minutes. This combination was given on day 1 every 2 weeks. The dose levels examined are shown in the Table . A total of 26 patients were studied (18 male, 8 female) with median age of 56 (range 41–83 years); ECOG performance status of 24 patients were 0 (5), 1 (16), 2 (2), 3 (1); prior chemotherapy ranged from 0 to 4 regimens; median number of cycles administered per patient was 3 (range 1–9) with a total of 81 cycles. The primary tumors were lung (11), melanoma (4), head and neck (3), squamous cell penile/toe (2), bladder (2), kidney (1), gastric (1), esophageal (1) and ovary (1). Results: No DLTs were seen in any of these patients and the MTD was not reached. Delay in treatment was seen in total of 6 cycles due to myelosuppression and 1 cycle due to nausea and anorexia. Grade 3/4 hematological toxicity rates: anemia - 3/81 cycles (3.7%), neutropenia - 20/81 cycles (25%), and thrombocytopenia - 4/81 cycles (5%). Non-hematological toxicity was mild. The median time to progression was 40 days (range 4–133) and of 18 evaluable patients partial response or stable disease was seen in 7 (38.8%). Conclusions: Even at maximum tested dose of GEM at 2000 mg/m2 and CBDCA at AUC of 3.0, this schedule is well tolerated. Hematological toxicity such as neutropenia and thrombocytopenia was minimal. We plan to study this schedule of GEM and CBDCA in appropriate tumor types in combination with biologic agents. [Table: see text] [Table: see text]

14025 Background: Metastatic SBA and ampullary adenocarcinoma (AAC) are incurable, aggressive malignancies. Limited data exists regarding the role of systemic chemotherapy in these diseases. Given the marked activity of CAPOX in other cancers of the gastrointestinal tract, we have investigated the activity of this combination in these two tumor types. Methods: Patients (pts) with either metastatic or unresectable SBA and AAC who had adequate organ function, ECOG performance status (PS) ≤2 and measurable disease per modified RECIST criteria were enrolled. Prior use of 5-FU or capecitabine as adjuvant therapy, neoadjuvant therapy, or with radiation was allowed. CAPOX was administered as a 21 day cycle with oxaliplatin 130mg/m2 IV on day 1 and capecitabine 750mg/m2 PO BID days 1–14. Up to 30 pts will be enrolled. The primary endpoint is overall response rate (ORR). Results: Eleven pts have been enrolled from 11/04 to 12/05 (6 with AAC and 5 with SBA). Ten pts have received ≥2 cycles and are evaluable for response. All pts had metastatic disease and none had received prior chemotherapy. Patient (pt) characteristics: median age 59 (49–76); M/F (4/7); 91% PS 0–1. Grade 3/4 toxicities included fatigue (5), neuropathy (1), anorexia (1), thrombocytopenia (1), hypokalemia (1), hyponatremia (1), and musculoskeletal (1). Common grade 1/2 toxicities included neuropathy (8), nausea (8), diarrhea (6), and fatigue (5). Four pts required dose reduction and 1 pt discontinued due to toxicity (grade 3 fatigue). Six pts, 3 AAC and 3 SBA, responded with an ORR of 60% (95% CI 31 to 83%). Five responses have been confirmed and 1 AAC pt obtained a complete response after 5 cycles of treatment. Median time to progression was 6.8m (95% CI 4.4 to 9.3+m). Conclusions: The combination of CAPOX is both well-tolerated and highly active. The ORR of 60% is one of the highest yet reported in the literature for the treatment of adenocarcinoma of the small bowel and ampulla of Vater. Enrollment continues on this trial.

14599 Background: We prospectively conducted a phase II trial to test the efficacy and safety of irinotecan, 5-fluorouracil and leucovorin (FOLFIRI) regimens for the first-line treatment of previously untreated patients with recurrent or metastatic advanced CRC. Methods: Thirty-four previously untreated patients with advanced CRC were enrolled in this study from June 2001 to December 2006. Eligible patients had histologically confirmed adenocarcinoma, no prior systemic therapy in palliative setting, ECOG PS = 2, adequate organ function, written informed consent and at least one measurable disease. The patients received either irinotecan 180 mg/m2 on day 1 with a LV bolus of 200 mg/m2 and a FU bolus of 400 mg/m2, and this was followed by a FU continuous infusion of 600 mg/m2 on day 1 and day 2 (the classic FOLFIRI regimen), or they were treated with a LV bolus of 400 mg/m2 and a FU bolus of 400 mg/m2 followed by a FU continuous infusion of 2,400 mg/m2 for 46 hours (the simplified FOLFIRI regimen), and these treatments were repeated every 2 weeks until disease progression. Results: There were 13 females and 21 males with median age of 54 years (range: 41–79). The most common metastatic sites were lung and liver. A total of 262 cycles were administrated with median 6 cycles per patient (range: 1–22). All pts were evaluable for toxicity, and 30 pts for response to the treatment. The objective response rate was 26.4% with 2 complete responses respectively. Sixteen (47%) pts had stable disease and 7 (20.5%) had a progression. The tumor control rate was 73.4%. The median TTP was 5.3 months, and the overall survival was 10.1 months. The prognostic factor for longer TTP and survival was the ECOG performance status (PS). The type of regimens was not affected on response rate, TTP and survival. The chemotherapy was generally well tolerated and the most common grade 3–4 toxicities were neutropenia, diarrhea. The non- hematological toxicities were similar for both treatment groups, with more frequent grade =3 neutropenia being noted for the simplified FOLFIRI regimen. Conclusions: The FOLFIRI regimen was demonstrated to have a moderate antitumor activity with acceptable toxicity profiles, and tend to show more favorable outcome for patients with good ECOG PS. No significant financial relationships to disclose.

Low Dose Chemotherapy

e17500 Background: Majority of patients with SCLC present with advanced stage and poor ECOG performance status. Hence delivery of adequate dose of chemotherapy is compromised. We hypothesized that initial low-dose chemotherapy might improve PS and enable administration of standard-dose chemotherapy, thus extending benefit of chemotherapy to otherwise ineligible patients. Methods: 30 patients with ECOG performance status 2-4 received low-dose chemotherapy consisting of either single agent carboplatin at AUC 2 or an abbreviated course of platinum-etoposide. Patients whose PS improved got full-dose chemotherapy with the standard regimen of platinum-etoposide. Demographic details, toxicity, time to progression and overall survival were analyzed. Univariate and multivariate analysis was performed to determine factors associated with TTP and OS. Results: Median age was 58 years with male predominance. The PS was IV in 9, III in 20 and II in 1 patient. Extensive-stage and limited-stage disease was seen in 24 and 6 patients respectively.15 patients received single-agent carboplatin, 10 patients abbreviated cisplatin-etoposide, 1 patient each cyclophosphamide and cisplatin-etoposide and 3 patients refused chemotherapy. Major grade 3-4 toxicity was mucositis in 1, loose motions in 1 and hyponatremia in 4 patients. There was no grade 3- 4 haematological toxicity. The median number of dose-reduced cycles was 1 and 3 patients received more than 2 cycles. 22 patients were eligible and willing for full-dose chemotherapy. The median time to start of full-dose chemotherapy was 11.5 days (4-26 days). The median number of cycles of standard-dose chemotherapy was 5 (1-6) with 16 completing planned schedule. Grade 3-4 toxicity was neutropenia in 50%, febrile neutropenia in 25%, loose motions in 25% and hyponatremia in 40%. The overall TTP and OS was 182 days and 263 days respectively. Presence of SIADH (p = 0.02) and completion of standard treatment (p = 0.001) had a positive impact on TTP while completion of treatment (p = 0.01) and normal LDH (p = 0.03) had a positive impact on OS. Conclusions: Low-dose chemotherapy is well-tolerated and might help in extending the benefit of standard-dose chemotherapy to otherwise ineligible patients.

294 Background: Currently, there are no standard treatments for relapsed or refractory urothelial carcinoma (UC). Discouraging results have been observed in trials evaluating established chemotherapeutics as single agents or in combination regimens. Paclitaxel has moderate activity when used alone and in combination in UC. Pazopanib is active in other solid tumors secondary to its potent anti-angiogenic effects. We report the results of a multi-center phase II study evaluating the combination of paclitaxel with pazopanib in refractory UC. Methods: Eligible patients (pts) had histologically confirmed UC, with disease that progressed on upto 2 chemotherapeutic regimens. Pazopanib (800 mg) was administered daily, with weekly paclitaxel (80mg/m2) for 3 weeks in a 28 day cycle. Treatment was continued until disease progression or unacceptable toxicity. The primary endpoint of the study was response-rate (RR) based on RECISTv 1.1 criteria. Secondary endpoints included safety, and progression free-survival (PFS). Results: From April 2010 to September 2014, 32 patients were enrolled. Median age was 67 years (29-89) and median ECOG performance status was 1 (0-2). 17 pts (54%) had UC of the upper urinary tract disease and 15(47%) had primary bladder tumors. All pts had multiple metastatic sites, including 9 (28%) with liver metastases. Median number of prior cytotoxic regimens was 2, and 50% were considered cisplatin responsive. Objective responses were observed in 58% with 3 (12%) complete responses (CR), and 12 pts (46%) with partial responses (PR). Another 9 (35%) acheived stable disease (SD). High grade toxicities included grade 3 hypertension (n=2), grade 3 fatigue (n=4), grade 3 thrombosis (n=2) and grade 4 neutropenia (n=2). Nearly half of the patients( n= 14 ) required growth factor support. Conclusions: Our phase II study combining paclitaxel and pazopanib demonstratedsignificant anti-tumor activity in relapsed/refractory UC. This combination is safe, effective and is worthy of evaluation in randomized phase 3 study. Clinical trial information: NCT01108055.

9507 Background: Brain metastases (BMts) are a major cause of morbidity/death in MEL. We report the first efficacy data in MEL patients (pts) with BMts who received NIVO+IPI in study CheckMate 204. Methods: In this multicenter US trial (NCT02320058), MEL pts with ≥1 measurable BMt 0.5-3.0 cm and no neurologic symptoms or steroid Rx received NIVO 1 mg/kg + IPI 3 mg/kg Q3W x 4, then NIVO 3 mg/kg Q2W until progression or toxicity. Pts with severe adverse events (AEs) during NIVO+IPI could receive NIVO when toxicity resolved; stereotactic radiotherapy (SRT) was allowed for brain oligo-progression if an assessable BMt remained. The primary endpoint was intracranial (IC) clinical benefit rate (complete response [CR] + partial response [PR] + stable disease [SD] > 6 months). The planned 90-pt accrual is complete; we report efficacy and updated safety for 75 pts with disease assessment before the Nov 2016 database lock. Results: Median age was 59 yrs (range 22–79). Median number of induction doses was 3; 26 pts (35%) received 4 NIVO+IPI doses and 38 pts (51%) began NIVO maintenance. Response data are reported at a median follow-up of 6.3 months (Table). The IC objective response rate (ORR) was 56% (95% CI: 44–68); 19% of pts had a complete response. IC and extracranial responses were largely concordant. Rx-related grade 3/4 AEs occurred in 48% of pts, 8% neurologic, including headache and syncope. Only 3 pts (4%) stopped Rx for Rx-related neurologic AEs. One pt died of immune-related myocarditis. Conclusions: In CheckMate 204, prospectively designed to investigate NIVO+IPI in MEL pts with BMts, NIVO+IPI had high IC antitumor activity with objective responses in 56% of pts, CR in 19%, and no unexpected neurologic safety signals. The favorable safety and high anti-melanoma activity of NIVO+IPI may represent a new Rx paradigm for pts with asymptomatic MEL BMts and could change practice to avoid or delay whole brain RT or SRT.
