9540 Background: Inhibitors of mTOR have demonstrated activity in preclinical pediatric solid tumor models. A phase I trial to define the dose limiting toxicities (DLTs) associated with the mTOR inhibitor TEM in combination with IRN and TMZ was conducted in patients (pts) with refractory solid tumors. Methods: Escalating doses of TEM were administered intravenously on days (d) 1 and 8 of a 21-d cycle for a maximum of 1 year (y). IRN (50 mg/m2/dose) was administered orally on d1-5. TMZ (100 mg/m2/dose) was administered orally on d1-5. When the maximum planned dose of TEM was reached (35 mg/m2/dose), IRN was escalated stepwise from 50 to 90 mg/m2/dose. Pts were enrolled on 6 dose levels using the rolling-six design. Results: 46 eligible pts (30 male, median age 11y, range 1 – 21) were enrolled; 37 were fully evaluable for toxicity [neuroblastoma (9), osteosarcoma (4), Ewing sarcoma (3), rhabdomyosarcoma (3), CNS (10) or other (8) tumors]. 173 cycles, median 2 (range 1 – 17) have been delivered. Dose-limiting hyperlipidemia was observed during cycle 1 in 2 pts at dose level 3 (TEM 25 mg/m2, IRN 50 mg/m2, TMZ 100 mg/m2); both pts were on chronic corticosteroids. The protocol was amended to preclude chronic systemic steroid use and modify hyperlipidemia management. Dose-limiting hyperlipidemia was not observed in subsequent pts. Cycle 1 DLT (elevated GGT) was observed in 1 pt treated with TEM 35 mg/m2, IRN 65 mg/m2, TMZ 100 mg/m2. DLT has not been observed in 4 of the first 6 pts treated at the highest planned dose level (TEM 35 mg/m2, IRN 90 mg/m2, TMZ 100 mg/m2). Additional ≥Grade 3 regimen-related toxicities occurring in >1 evaluable pt include neutropenia (12), lymphopenia (10), leukopenia (6), thrombocytopenia (4), anemia (2), nausea or vomiting (5), hypokalemia (4), hypophosphatemia (2), diarrhea (2), elevated transaminases (2), and infection (2). 1 pt had a Grade 3 allergic reaction to TEM. 1 pt had a confirmed partial response and 4 have remained on protocol therapy for ≥1 year. Conclusions: The combination of TEM (35 mg/m2/dose) d 1 and 8, IRN (90 mg/m2/dose) d 1-5, and TMZ (100 mg/m2/dose) d 1-5 of a 21-d cycle appears to be well tolerated in children with refractory solid tumors.

3096 Background: In preclinical studies, combination of sirolimus with gemcitabine enhances apoptosis in vitro and increases anti-tumor efficacy in vivo. Methods: Patients with advanced solid tumors, age 18-70 years, no prior mTOR inhibitor or gemcitabine, ECOG PS 0-1, and adequate hematological, renal and hepatic function, were enrolled in this phase I study to assess safety, tolerability, pharmacokinetics (PK), and to identify the dose limiting toxicity (DLT), maximum tolerated dose (MTD) and recommended dose (RD) of the combination of sirolimus and gemcitabine. A 3+3 dose escalation design with cohorts of 3-6 patients was used. Sirolimus was given po continuously. Gemcitabine was given iv 10mg/m2/minute on days 1 and 8 every 3 weeks. Dose levels 1, 2 and 3 corresponded to sirolimus 2, 2 and 5mg/24h plus gemcitabine 800, 1000 and 1000mg/m2 respectively. After observing DLTs at higher dose level and poorer mTOR signaling inhibition at lower doses, a new cohort of sirolimus 5mg/24h plus gemcitabine 800 mg/m2 was added. Skin biopsies pre and post treatment were performed to assess the inhibition of mTOR pathway. Results: 19 patients were enrolled: median age 51 years (36-70); gender 12M, 7F. Median number of cycles was 4. Patients were treated at 4 dose levels, the MTD was reached at level 3 and the RD was: sirolimus 5mg/24h and gemcitabine 800mg/m2. 3 DLTs were observed, 1 at dose level 2 and 2 at dose level 3: transaminitis grade 3, thrombocytopenia grade 3 and thrombocytopenia grade 4. Other toxicities grade 1-2 included anemia, neutropenia, asthenia, mucositis and high cholesterol levels. 2 patients achieved partial response (1 uterine cervix cancer and 1 colon cancer). Immunohistochemistry of pS6 in skin biopsies showed significative inhibition of mTOR pathway at RD. PK parameters estimated were in agreement with those previously reported in the literature. No influence of sirolimus administration on gemcitabine clearance was found. Conclusions: Combination of sirolimus and gemcitabine is feasible and safe, allowing administration of active doses of both agents and achieving mTOR signaling inhibition. A phase II study to assess the activity of this combination in sarcomas is ongoing.

150 Background: Everolimus is able to stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving everolimus together with hormonotherapy and radiation therapy may kill more tumor cells. Methods: We conducted a phase I trial to evaluate the impact of everolimus (RAD001), an mTOR inhibitor, in patients treated concurrently with radiotherapy (RT) and ablative androgen treatment in high-risk locally advanced prostate cancer. Inclusion criteria were high-risk locally advanced non metastatic prostate cancer defined as clinical stage ≥ T3 or Gleason score ≥ 8 or PSA ≥ 20. The week before the beginning of RT, RAD001 was administered at different dose levels, twice daily, until the last day of irradiation. A nonsteroid antiandrogen was also given for 1 month at the beginning of RT. Prostate and seminal vesicle were irradiated up to 74Gy in 37 fractions of 2Gy with concomitant long-term LHRH analogue. The starting dose of RAD001 was 5mg/d with subsequent dose levels of 7.5 and 10 mg/d. The primary endpoint was the determination of the maximum tolerated dose (MTD). Dose escalation was implemented according to the continual reassessment method (CRM). Results: Fifteen patients were enrolled and 14 were assessable for toxicity and response. Significant toxicities were demonstrated at the 7.5 and 10 mg/d dose levels. Dose-limiting toxicity (DLT) occurred in two patients at dose level 7.5 mg/d and characterized by a grade 3 diarrhea and a grade 3 hydronephrosis due to dehydration and kidney lithiasis. DLT also occurred in two patients at dose level 10 mg/d (grade 3 diarrhea and grade 3 laryngopharyngeal infection). The MTD was reached at 7.5 mg/day (dose-level II). The recommended dose of RAD001 was 5 mg/d. After a median follow-up of 22 months, 12 patients are alive, 1 is dead (not related to cancer) and 2 patients had relapsed. Conclusions: Concomitant hormone-radiotherapy and everolimus is well-tolerated with mucositis, hypercholesterolemia, and urinary disorders. The recommended phase-II trial dose of everolimus in this combined setting is 5 mg/day. Clinical trial information: NCT00943956.

18145 Background: Bortezomib (Vc) is a novel proteosome inhibitor with activity in several malignancies including multiple myeloma, mantle cell lymphoma, and NSCLC. In NSCLC, Vc has additive activity combined with carboplatin and gemcitabine in first line and with docetaxel in second line treatment. Pemetrexed (P) is active in NSCLC and preclinical data suggests a pro-apoptotic synergy between Vc and P. Therefore, we initiated a phase I/II dose finding study of Vc + P in previously-treated patients (pts) with advanced or metastatic NSCLC. Methods: Fifteen pts have been accrued to 3 of 4 planned dose levels of Vc + P. Starting doses (and # pts treated) were Vc 1.4 mg/m2 day 1 & 8 + P 400 mg/m2 day 1 every 3 weeks (3 pts). The 2nd and 3rd dose levels were Vc 1.6 mg/m2 day 1 & 8 + P 500 mg/m2 day 1 (8 pts, 5 new + 3 from dose level 1) and Vc 1.8 mg/m2 day 1 & 8 + P 500 mg/m2 day 1 (7 pts). Results: 15 pts are evaluable for response and toxicity and include 8 males, 7 females, median age 67 (range, 55–82), PS 0/1 (3/12 pts), median of 2 prior therapies (range 1–3). Confirmed PRs occurred in 2 pts (13%) and stable disease in 5 (33%). Dose limiting toxicities consisted of grade 4 fatigue (1 pt) and neutropenia/fever (1 pt) at dose level 2, and grade 3 abdominal pain and fatigue (1 pt) and grade 3 diarrhea and vomiting (1 pt) at dose level 3. Conclusions: The above combination is safe at the doses tested thus far and active in pts with heavily pretreated, advanced NSCLC. We are currently exploring Vc 2.0 mg.m2 Day 1 & 8 + P 500 mg/m2 day 1 every 3 weeks to determine the MTD and plan a multi-site Phase II study to determine response rate and survival in a larger pt population.

2561 Background: Becatecarin (rebeccamycin analogue-RA) is an anti-tumor antibiotic with inhibitory activity against both topoisomerase II and I as well as DNA intercalating properties. We performed a phase I trial to a) determine the maximum tolerated dose (MTD) of RA in combination with oxaliplatin; b) determine the dose limiting toxicities (DLT) (c) obtain data on pharmacokinetics and (d) observe for any antitumor activity. Methods: Eligibility criteria included patients with advanced solid tumors refractory to standard therapy; performance status 0–2; adequate hematologic, renal and liver function. Patients were treated with RA as a 1 hour infusion daily x 5 and oxaliplatin on day 5 only, after RA infusion. Treatment was repeated q 21 days. The following dose levels were evaluated: Dose level 1: RA 80 mg/m2/d and oxaliplatin 90 mg/m2; Dose level 2: RA 80 mg/m2/d and oxaliplatin 130 mg/m2; Dose level 3: RA 110 mg/m2/d and oxaliplatin 130 mg/m2. Results: A total of 15 evaluable patients were enrolled. Median age was 56 (8 male, 7 female). A variety of tumor types were enrolled. A total of 56 cycles were administered. DLT occurred at a dose of RA at 110 mg/m2/d x 5 days and oxaliplatin at 130 mg/m2 and consisted of grade 3 hypophosphatemia and grade 4 atrial fibrillation. At this dose level 2 of 3 enrolled patients also developed grade 3 neutropenia. The MTD and recommended phase II dose was RA at 80 mg/m2/daily x 5 along with oxaliplatin 130 mg/m2 day 5 q 21 days. Three confirmed partial responses were observed in patients with hepatocellular, gallbladder and esophageal cancers. Six patients experienced stable disease. Conclusions: At the MTD combination RA and oxaliplatin is well tolerated and given the response rate and stable diseases observed, phase II studies are recommended.

146 Background: Intraperitoneal (IP) chemotherapy is a promising treatment option for gastric cancer with peritoneal metastasis. We previously verified the safety and efficacy of IP paclitaxel (PTX) combined with S-1 and intravenous PTX in phase I and phase II studies. S-1 plus oxaliplatin (SOX) demonstrated efficacy in a phase II study, and is regarded as a candidate for the next-generation standard regimen for gastric cancer. We designed a new regimen combining weekly IP PTX with SOX in order to maximize systemic effects as well as local effects in the peritoneal cavity. A dose-escalation study of IP PTX in combination with fixed doses of SOX was carried out to determine the maximum-tolerated dose (MTD) and recommended dose (RD). Methods: PTX was administered intraperitoneally on days 1 and 8 with an initial dose of 20 mg/m2 (level 1), stepped up to 30 mg/m2 (level 2) or 40 mg/m2 (level 3) depending on observed toxicity. S-1 was administered orally at a dose of 80 mg/m2/day (b.i.d.) for 14 days followed by a 7-day rest. Oxaliplatin was administered intravenously at a dose of 100 mg/m2 on day 1. This treatment was repeated every 3 weeks. Toxicity was graded according to CTCAE v4.0. Dose-limiting toxicities (DLTs) were defined as grade 4 leukopenia, grade 3 febrile neutropenia, grade 3 thrombocytopenia, and grade 3 non-hematological toxicity. The MTD was defined as the dose level at which 2 or more of 3 or 6 patients developed DLTs during two courses of treatment. The RD was defined as one dose level under the MTD. Results: A total of 12 gastric cancer patients with peritoneal metastasis were enrolled. No DLTs were observed at all dose levels. Neutropenia in one patient at dose level 3 was the only grade 3 toxicity observed. Grade 2/3 leukopenia, neutropenia and thrombocytopenia were observed only in 2 patients at dose level 3. Regarding grade 2 non-hematological toxicities, anorexia, fatigue and nausea were observed in 6, 4 and 2 patients, respectively, independent of dose levels. Consequently, the MTD was not reached, and the RD of IP PTX was determined to be 40 mg/m2 (level 3). Conclusions: Combination chemotherapy of IP PTX with SOX was shown to be a safe regimen that should be further explored in clinical trials.

10013 Background: IMC-A12, a fully human IgG1 monoclonal antibody to the Insulin-Like Growth Factor-I Receptor (IGF-IR), is active preclinically in a variety of pediatric solid tumors. We performed a phase I trial to determine the toxicities, maximum tolerated dose (MTD), pharmacokinetics (PK), and pharmacodynamics (PD) of IMC-A12 in children with refractory solid tumors. Methods: IMC-A12 was administered as a weekly 1 hr IV infusion, without interruption. Two dose levels, 6 and 9 mg/kg, were evaluated using a standard 3+3 cohort design. After defining initial safety, patients (pts) with refractory Ewing sarcoma (ES) were treated in an expanded cohort at each dose level. Results: 24 eligible patients (11 male), median 15.3 yrs (range, 7.0 to 21.5), were enrolled. Among the 12 pts enrolled on the dose-escalation component, DLT (grade 4 thrombocytopenia) occurred in 1/6 pts at 6 mg/kg. No DLTs occurred in 6 pts at 9 mg/kg or in the ES cohort. 1/10 evaluable pts with ES at the 6 mg/kg dose had a partial response; no CRs were observed. Grade 2 or higher non-DLTs possibly attributable to IMC-A12 observed in the first course include anemia (n=4), leukopenia (n=1), lymphopenia (n=2), neutropenia (n=2), opportunistic infection (n=1), ↑liver transaminases (n=2), and hyperglycemia (n=1). No ≥ grade 3 hyperglycemia occurred. Mean (± SD) trough IMC-A12 concentrations were 59.8 ± 31.1 and 117 ± 70.8 μg/ml at the 6 and 9 mg/kg dose levels, respectively. A majority of pts at both dose levels exhibited > 50% reduction in PBMC IGF-IR protein levels. Conclusions: In order to exceed target trough concentrations associated with optimal anti-tumor activity in pre-clinical models, 9 mg/kg IV weekly is the recommended Phase II IMC-A12 dose in children. A phase II protocol for children with refractory solid tumors will be performed. [Table: see text]

3564 Background: Heat shock protein 90 (HSP90) is a molecular chaperone involved in the maintenance and function of client proteins, many of which are integral to key oncogenic processes. AUY922 is a competitive inhibitor of HSP90. Preclinical evidence suggests potential synergy between HSP90 inhibition and fluorouracil. This phase I study was designed to determine the maximum tolerated dose (MTD) of AUY922 in combination with standard dose of capecitabine as treatment for patients with advanced solid tumors. Methods: Pts with refractory solid tumors received AUY922 with capecitabine in a standard 3+3 dose escalation. Dose levels were capecitabine 1000mg/m2 PO BID d 1-14 of 21-day cycles, with escalating doses of AUY922 IV days 1, 8, and 15; the 6th dose level combined the MTD of AUY922 with capecitabine 1250mg/m2. Dose-limiting toxicities (DLTs), safety, and efficacy were evaluated. Results: 23 pts were treated at 6 dose levels: 22mg/m2 (n = 3); 28mg/m2 (n = 3); 40mg/m2 (n = 3); 55mg/m2 (n = 5); 70mg/m2 (n = 3); 70mg/m2 with capecitabine 1250mg/m2 (n= 6). No DLTs were observed until the 6th dose level (grade 3 diarrhea). Related adverse events (% grade 1/2; % grade 3/4) included: diarrhea (43%; 17%), fatigue (30%; 13%), nausea (39%; 0), hand-foot skin reaction (30%; 5%), anorexia (30%; 4%), vomiting (30%; 0), and darkening vision (26%; 0). Vision darkening, a class effect of HSP90 inhibitors, was reversible with drug hold and retreatment was possible. Two pts (9%) had hematologic G 3/4 events of neutropenia. Of the 19 pts evaluable for response, partial response was noted in 4 patients (colorectal, 2; breast, 1; stomach, 1); 2 had progressed on prior fluorouracil, and remained on treatment for 13-35 wks. Stable disease was noted in 8 pts (35% [colorectal, 5; pancreas, 2; breast, 1]) with a median duration of 25.5 wks (range: 11-44+). All 5 colorectal pts were refractory to 5-FU. Conclusions: The addition of AUY922 to standard dose capecitabine was well-tolerated at doses of up to 70mg/m2. Preliminary efficacy is encouraging, particularly as seen in pts previously resistant to fluorouracil, and warrants further investigation of this regimen. Clinical trial information: NCT01226732.

PURPOSE The objectives of this phase I trial were to determine the dose-limiting toxicities (DLTs) of the novel topoisomerase I inhibitor topotecan combined with cisplatin, to define the maximum-tolerated doses (MTDs) of the combination without and with the use of filgrastim, and to define recommended doses for phase II trials. PATIENTS AND METHODS Patients with advanced solid tumors were eligible if they had normal bone marrow, renal, and hepatic function and had not previously been treated with platinum compounds. Topotecan was administered intravenously on days 1 through 5 and cisplatin was administered intravenously on day 1 of a 21-day cycle. The topotecan dose was fixed at 1.0 mg/m2/d on the first four dose levels, and cisplatin was escalated in 25-mg/m2 increments from 25 to 100 mg/m2 without filgrastim. After encountering DLT, the dose of cisplatin was decreased by one level and topotecan dose escalation was attempted. After defining the MTD without growth factor, the study proceeded with escalating cisplatin doses to define the MTD with filgrastim 5 micrograms/kg subcutaneously (SC) daily starting on day 6 of treatment. Priming with filgrastim 5 micrograms/kg SC on days -6 to -2 before the first course was explored last. RESULTS Of 38 patients entered, 37 were eligible, 35 assessable for toxicity in the first course, and 28 assessable for response. The principal toxicity was grade 4 neutropenia, which had to last more than 7 days to be considered dose-limiting. No DLT was observed at the starting cisplatin dose of 25 mg/m2 (dose level 1). On level 2 (cisplatin 50 mg/m2, one patient had dose-limiting neutropenia and one patient had grade 3 renal toxicity. On level 3 (cisplatin 75 mg/m2), two patients had dose-limiting neutropenia. Therefore, cisplatin dose escalation was stopped. On dose level 5 (cisplatin 50 mg/m2 and topotecan 1.25 mg/m2/d), one patient had grade 4 neutropenia that lasted more than 7 days and one patient died of neutropenic sepsis. The remaining dose levels used topotecan 1.0 mg/m2/d plus cisplatin 75 mg/m2 (level 6) and 100 mg/m2 (levels 7 and 8) with filgrastim. No DLT was observed on level 6. On level 7, two patients had dose-limiting neutropenia and one patient had grade 3 hyperbilirubinemia. Priming with filgrastim on level 8 demonstrated no obvious advantage over level 7, and one patient had grade 4 thrombocytopenia that lasted more than 7 days. Three patients with non-small-cell lung cancer achieved a partial response and one patient with breast cancer had a complete response. CONCLUSION Topotecan and cisplatin in combination cause more neutropenia than expected from either drug given alone at the same dosage. The recommended phase II doses are topotecan 1.0 mg/m2/d for 5 days in combination with cisplatin 50 mg/m2 on day 1 without filgrastim or cisplatin 75 mg/m2 on day 1 with filgrastim support.

e15580 Background: The antiangiogenic tyrosine kinase inhibitor regorafenib provides a survival benefit in patients with previously treated metastatic colorectal cancer. Antiangiogenic therapy causes hypoxic stress within tumor cells, which activate autophagy as a survival mechanism. Entinostat, a histone deacetylase (HDAC) inhibitor, increases dependence on autophagy through epigenetic mechanisms. Hydroxychloroquine (HCQ) blocks autophagy by blunting lysosomal acidification and is synergistic with antiangiogenic therapies. We hypothesized that HCQ and entinostat would be tolerable with regorafenib and potentiate the antitumor response. Methods: This was a 3+3 phase I trial to find the recommended phase II dose (RP2D) of HCQ and entinostat with regorafenib in patients with metastatic colorectal cancer previously treated with a fluoropyrimidine, oxaliplatin, and irinotecan. No prior regorafenib or HDAC inhibitor therapy was permitted. Regorafenib was dosed at 160mg daily on days 1-21 of 28-day cycles, with provision to lower the starting dose to 80mg if toxicity was excessive. Entinostat was dosed at 3mg weekly in dose level 1 and at 5mg weekly in dose levels 2 and 3 while HCQ was dosed at 200mg qAM and 400mg qPM in dose levels 1 and 2 and at 600mg BID at dose level 3. Expansion was planned at the RP2D with a primary endpoint of objective response rate. Results: Twenty-eight patients were screened, and 20 patients were enrolled from November 2017 to January 2020. Six patients were treated at dose level 1 with no dose-limiting toxicity. The starting regorafenib dose was reduced to 80mg after 3 patients discontinued therapy early due to fatigue or rash due to regorafenib. At dose level 2, 7 patients were enrolled to achieve 6 evaluable patients. One DLT (G3 fatigue) was noted and one patient withdrew consent after 14 days due to fever and tumor pain flare possibly related to treatment. Six patients enrolled at dose level 3; no DLTs were seen. One additional patient received HCQ 400mg BID instead of 600mg BID due to a clerical error. Weight loss (60%), fatigue (50%), and anorexia (50%) were the most common toxicities. Thirteen grade 3 toxicities were noted, with rash (15%), fatigue (10%), and alkaline phosphatase elevation (10%) the most common. No grade 4 toxicities were observed. Seven patients discontinued therapy early due to toxicity. Nearly all patients experienced rapid weight loss, with a range of 1.5 lbs to 27.1 lbs and a median weight loss of 9.5 lbs at two weeks. No objective responses were observed. The median PFS was 1.8 months, the median OS was 5.2 months, and no patient remained on study longer than 4 months. Expansion was not pursued due to toxicity and lack of efficacy. Conclusions: The combination of regorafenib, HCQ, and entinostat was poorly tolerated without evident activity in metastatic colorectal cancer. The substantial weight loss suggests a potential adverse metabolic interaction between these drugs. Clinical trial information: NCT03215264.

14046 Background: The Brown University Oncology Group has attempted to modify the regimen of docetaxel, cisplatin and fluorouracil (DCF) to reduce toxicity, simplify administration and maintain efficacy. We have a completed a phase I/II study of weekly doxetaxel, carboplatin and capecitabine for patients with advanced esophagogastric cancer (Safran et al, Am J Clin Oncol, 2006). In this phase I study we have substituted oxaliplatin for carboplatin to determine the maximum tolerated dose (MTD) of weekly docetaxel and oxaliplatin with capecitabine. Methods: Patients with metastatic esophageal and gastric cancers received docetaxel and oxaliplatin on days 1 and 8 and capecitabine in divided doses, twice daily, on days 1–10, with each cycle repeated every 21 days. Patients were treated at 4 dose levels as shown in the table. Results: Fourteen patients have been enrolled. The median age was 58.5 years. Eight patients had esophageal cancer and six had gastric cancer. Grade 3/4 dose limiting toxicities (DLTs) of diarrhea, nausea, and febrile neutropenia occurred in three of four patients at dose level 3. An intermediate dose level was added (2A), reducing the capecitabine dose. Conclusion: Oxaliplatin 50 mg/m2 and docetaxel 35 mg/m2 day 1 and 8 with capecitabine 750 mg/m2 BID × 10 days in 21 day cycles may represent a promising, easily administered regimen for metastatic esophageal and gastric cancer. Enrollment continues at dose level 2A. [Table: see text] [Table: see text]
