10020 Background: Children with DIPG have a dismal prognosis despite use of RT, which is the mainstay of therapy. All chemotherapy regimens used so far demonstrated no benefit. EGFR and VEGFR pathways are considered important in tumorigenesis of DIPG. Methods: We conducted a traditional phase I study combining oral vandetanib (VEGFR-2 and EGFR inhibitor) during and after local RT in children with DIPG. Five dosage levels were tested (50, 65, 85, 110, and 145mg/m2 per day). Vandetanib and RT started on the same day. The first 6 weeks of therapy constituted the dose-limiting toxicity (DLT)-evaluation period. Correlative studies consisted of pharmacokinetic analysis (PK), pharmacodynamic studies in blood, and standard and investigational imaging (before and 1, 3, and 6 weeks after start of therapy). Results: Twenty-one patients were enrolled on study (50 [n = 3], 65 [n = 3], 85 [n = 3], 110 [n = 6], and 145mg/m2 [n = 6]). Two patients experienced DLT consisting of rash/mucositis (level 4) and diarrhea (level 5). The maximum-tolerated dose (MTD) of vandetanib was not reached. Other significant toxicities included lymphopenia grade 3/4 (n = 10), grade 3 neutropenia and hypophosphatemia (one each), grade 2 proteinuria (n = 2), grade 2 hypertension (n = 4), and mild QTc prolongation (n = 7) .Once the phase I component was completed, two extra patients were enrolled at dosage level 5; one of them developed grade 4 seizure secondary to posterior reversible encephalopathy syndrome. PK (n = 21) showed similar drug clearance and volume of distribution compared to adults. However, drug exposure at steady state normalized by dose seemed higher in children. Increased tumor perfusion during the first 6 weeks of therapy was observed in the first 12 patients analyzed. Conclusions: Although MTD was not reached, we recommend administration of vandetanib at a dose of 110mg/m2 per day during and after local RT in children. Further combination studies of vandetanib in children with DIPG are planned. No significant financial relationships to disclose.

3592 Background: We designed a phase I study to determine maximum tolerated dose (MTD) of irinotecan when combined with sLV5FU2 in mCRC patients (pts). Methods: Pts were genotyped for UGT1A1 *28 and *6, and stratified into 3 groups according to the number of defective allele (DA), designated 0 (*1/*1), 1 (*1/*28, *1/*6), and 2 (*28/*28, *6/*6, *6/*28). Within each group, the dose of irinotecan was escalated (table) in combination with fixed dose of sLV5FU2. Plasma drug levels and dose-limiting toxicity (DLT) were evaluated at cycle 1. Results: A total of 43 pts were accrued: 19 for 0 DA, 20 for 1 DA and 4 for 2 DA group. The MTD was estimated as 300 mg/m2/2-week for the 1 DA group with 2 DLTs in the level 3, and the MTD was not reached for the 0 DA group with 1 DLT in the level 4 (table). The mean relative extents of glucuronidation, AUClast ratio of SN-38G to SN-38, were 9.36, 6.81, and 5.09 for the 0, 1, and 2 DA groups, respectively (P=0.017). Of the 43 pts, five pts showed AUClast, SN38 that exceeded 400 ng·h/mL (1.02 umol·h/L) and DLT was observed in 40% (2/5). The overall response rate was 67.4% (95% CI, 51.5-80.9) with 6 complete responses and 23 partial responses. Median progression-free and overall survival was 8.0 months (95% CI, 7.1-8.9) and 25.6 months (95% CI, 23.4-27.7), respectively. Grade 3 or 4 toxicity during all treatment cycles included neutropenia (79% [0 DA]; 90% [1 DA]; 75% [2 DA]), leucopenia (21%; 30%; 0%), febrile neutropenia (0%; 10%; 0%) and diarrhea (0; 5%; 0) per patient. Conclusions: Dose-normalized exposure of SN38 was significantly higher in the 2 DA UGT1A1 group. Higher doses of irinotecan based on UGT1A1 genotyping are feasible when combined with sLV5FU2 in mCRC pts. The recommended dose of irinotecan was 330, 270, 150 mg/m2/2-week for pts with 0, 1, 2 DA based on pharmacokinetic analysis. [Table: see text]

2568 Background: PM00104 is a novel synthetic alkaloid related to the marine compounds jorumycin and renieramycins. Preliminary preclinical studies suggest changes in cell cycle and DNA binding properties and transcriptional inhibition as main mechanisms of action. PM00104 has shown broad in vitro and in vivo anti-tumor activity (IC50 ≤ 10-8 M) with an acceptable toxicology profile. Methods: The aim of this phase I study was to assess the safety profile, dose-limiting toxicities (DLT), maximum tolerated dose (MTD), recommended dose (RD), pharmacokinetics (PK), relationship between PK and pharmacodynamics (PD) and anti-tumor activity of PM00104 administered as a 24-hour i.v. infusion q3w. Sequential cohorts of 3–6 pts were treated at 133, 266, 400, 800, 900, 1600, 3200, 4000 and 5000 μg/m2. Results: Twenty nine pts have been treated (18 male, 11 female; median age: 59, range: 44–78; ECOG PS ≤2). Five pts developed DLTs: 2 pts at 5000 μg/m2 (grade 4 thrombocytopenia/neutropenia and grade 3 nausea/vomiting in 1 pt; and grade 3 nausea in 1 pt); 1 at 4000 μg/m2 (grade 4 neutropenia/thrombocytopenia and grade 3 asthenia); 1 at 3200 μg/m2 (grade 3 tumor pain) and 1 at 266 μg/m2 (grade 3 transaminase increase). The MTD was reached at 5000 μg/m2 and the RD at 4000 μg/m2. At the RD 6 more pts have been included in order to further evaluate the safety profile and anti-tumor activity. Other adverse events included nausea and vomiting (more frequent at doses ≥800 μg/m2), fatigue, anorexia and diarrhea; most of them being of ≤grade 2 severity. No objective responses were seen but 3 pts with pancreatic adenocarcinoma, hepatocarcinoma and lower esophagus adenocarcinoma presented stable disease lasting >3 months. PM00104 shows a dose-proportional PK profile, the half-life being 20–30 hours and the volume of distribution around 1000 L. Conclusions: PM00104 has shown an acceptable safety profile with signs of anti-tumor activity in pts with advanced malignancies when administered as a 24-hour i.v. infusion q3w. PM00104 is also being evaluated with other administration schedules as monotherapy and in combination with other anti-tumor agents. [Table: see text]

Purpose: A phase I study was performed to determine the maximum-tolerated dose (MTD) and safety profile of irinotecan (CPT-11) administered as a single intravenous infusion every 3 weeks in children with recurrent or refractory solid tumors. Patients and Methods: Eighty-one patients were enrolled, including 48 less heavily, and 33 heavily pretreated patients (cranial irradiation and/or high-dose chemotherapy). Children received CPT-11 as a 120-minute infusion at doses ranging from 200 to 720 mg/m2. The dose-limiting toxicities (DLT) on first cycle were determined in both cohorts. Results: One hundred twenty-two cycles and 81 cycles were administered in less heavily, and heavily pretreated patients, respectively. The primary DLT was delayed diarrhea in less heavily pretreated patients, and neutropenia in heavily pretreated patients. MTD was 600 mg/m2 in both cohorts. Grade 3 to 4 neutropenia occurred in 33% and 38% of cycles in less heavily, and heavily pretreated patients, respectively. Grade 3 to 4 nonhematologic toxicities included nausea/vomiting (7% and 4% of cycles in less heavily, and heavily pretreated patients, respectively), asthenia (7% and 4% of cycles, respectively), and delayed diarrhea (6% and 2.5% of cycles, respectively). Four partial responses at 600 mg/m2 (high-grade glioma, neuroblastoma, medulloblastoma, and rhabdomyosarcoma) and 21 minor responses and stable diseases were observed. Pharmacokinetic analysis of CPT-11 and SN-38 was performed in 77 patients. The mean ± standard deviation (SD) CPT-11 plasma clearance was 20.7 ± 9.5 L/h/m2 (range, 5 to 54). The mean ± SD SN-38 metabolic ratio was 1.5% ± 1.1% (range, 0.15% to 5.55%). Conclusion: The recommended phase II dose of CPT-11 in a 3-week schedule is 600 mg/m2 in less heavily, and heavily pretreated children with solid tumors.

Abstract Genomic aberrations in the cell cycle and mTOR pathways have been reported in diffuse pontine gliomas (DIPG) and high-grade gliomas (HGG). Dual inhibition of CDK4/6 (ribociclib) and mTOR (everolimus) has strong biologic rationale, non-overlapping single-agent toxicities, and adult clinical experience. The maximum tolerated dose (MTD) and/or recommended phase two dose (RP2D) of ribociclib and everolimus administered during maintenance therapy following radiotherapy was determined in the phase I study as a rolling 6 design. Ribociclib and everolimus were administered once daily for 21 days and 28 days, respectively starting two-four weeks post completion of radiotherapy. All HGG patients and any DIPG patient who had undergone biopsy were screened for RB protein by immunohistochemistry. Eighteen eligible patients enrolled (median age 8 years; range: 2–18). Six patients enrolled at dose levels 1,2, and 3 without dose limiting toxicities (DLT). Currently, five patients are enrolled at dose level 3 expansion cohort. The median number of cycles are 4.5 (range: 1–20+). Among the expansion cohort, one dose limiting toxicity included a grade 3 infection and one patient required a dose reduction in course 3 due to grade 3 ALT and grade 4 hypokalemia. The most common grade 3/4 adverse events included neutropenia. Preliminary pharmacokinetic studies on 12 patients suggest an impact of ribociclib on everolimus pharmacokinetics. The MTD/RP2D of ribociclib and everolimus following radiotherapy in newly diagnosed DIPG and HGG is anticipated to be 170 mg/m2/day x 21 days and 1.5 mg/ m2/day every 28 days which is equivalent to the adult RP2D.

Abstract Phase I and II clinical studies demonstrated activity of Clofarabine in acute leukemias. In previous studies we have investigated clofarabine, plus ara-C combinations and reported a CR rate of 24% in relapsed AML and 52% in previously untreated AML ≥ 50 years (yrs) with acceptable toxicity profile. Anthracyclines are active in AML. To explore clofarabine further in AML combinations we conducted a phase I study of clofarabine with idarubicin with or without ara-C in pts with relapsed AML, MDS, and CML. Considered as dose-limiting toxicities (DLT) are ≥ grade 3 drug-related toxicities. Maximum tolerated dose (MTD) will be determined by “3+3” dose escalation scheme. On the clofarabine (C)/idarubicin (I) combination (CI), 9 AML pts are enrolled (2 primary refractory, 7 first relapse). Median age: 58 yrs (range 24–71). Median first remission duration (CRD1): 3.1 mos. (0–7.6). For the first dose level, C was given at 22.5mg/m2 i.v. daily x 5d and I at 12mg/m2 i.v. daily x 3d. Among the first 6 pts, 2 ≥ gr. 3 toxicities (diarrhea, rash, ↑ bili) occurred necessitating dose de-escalation of C to 15mg/m2 i.v. daily x 5 and I 8mg/m2 i.v. daily x 3. Among 3 pts, 1 ≥ gr.3 toxicity (↑ bili) was observed. No responses occurred. On the CI + ara-C arm (CIA), 7 AML pts are enrolled (1 primary refractory, 6 first relapse). Median age: 58 yrs. (24–78). Median CRD1: 11.2 mos. (0–13.1). First dose level: C 22.5mg/m2 i.v. daily x 5d, I 8mg/m2 i.v. daily x 3d, A 1g/m2 i.v. daily x 5d. Of 3 pts, 2 developed ≥ gr.3 toxicities (↑ bili, diarrhea) leading to the following de-escalation: C 15mg/m2 i.v. daily x 5d, I 6mg/m2 i.v. daily x 3d, A 0.75g/m2 i.v. daily x 5d. Of 4 pts (1 ≥ gr. 3 rash, ↑ bili), 3 pts achieved CR. The phase I study is ongoing until determination of DLT and MTD for each arm. Our preliminary results indicate clinical activity of CIA even at the low dose level.

12008 Background: Taxanes have demonstrated activity across a broad range of cancers, but resistance remains an issue. TPI 287 is a third generation taxane designed to overcome issues of resistance secondary to mdr and mutant tubulin. The purpose of this Phase I study was to determine the maximum tolerated dose and pharmacokinetics of IV TPI 287. Methods: Phase I study: TPI 287 is administered IV on days 1, 8, 15 of a 28 day cycle (Q7D) with at least 3 patients treated per dose escalation, in a typical phase I design. Dosing began at 7 mg/m2 and has advanced to the fifth cohort of patients, who are being treated at a dose of 85 mg/m2. Tumor response is assessed after every second cycle via imaging and tumor measurements. Samples are collected for PK analysis and circulating tumor cell (CTC) quantitation. Results: Sixteen pts have been enrolled (9 males, median years = 60.11; 7 females, median years = 50.71: median number of previous chemotherapies = 4). Diagnoses included colorectal (4), prostate (3), breast, kidney, cervical, brain, lung, osteosarcoma, basal cell, endometrial, ovarian cancers. Of 16 pts, 8 and 5 have completed 1, 2 cycles, respectively. Only one drug related grade 3 adverse event (hypersensitivity reaction) occurred, at 14 mg/m2. No other reported toxicities are related to TPI 287. PK and CTC studies are ongoing. Conclusions: These initial results show that TPI 287 is well tolerated at a dose up to 56 mg/m2 administered Q7D, and dose escalation continues. [Table: see text]

3082 Background: CX-3543 is a novel small molecule specifically designed to target three dimensional nucleic acid motifs, and thus induce apoptosis in cancer cells. Preclinically, CX-3543 demonstrated potency in suppressing xenograft tumor growth with a broad therapeutic window. The objectives of this phase I study are: to determine the maximum tolerated dose (MTD) and dose limiting toxicities (DLTs), to establish the pharmacokinetics (PKs), and to determine the recommended dose for further clinical development of CX-3543. Methods: Eligible patients with advanced solid tumors or lymphomas whose tumors progressed on standard therapy or for whom there are no standard therapies receive CX-3543 in successive dose cohorts at: 10, 20, 40, 80 and 160 mg/m2. Dosing is by one hour intravenous infusion daily for five consecutive days repeated on a three week cycle. Therapy is continued until the patient shows signs of intolerance to CX-3543 or evidence of advancing disease. Response by RECIST criteria is determined after every 2 cycles. Results: Ten patients with solid tumors (3–4 per cohort) have received intravenous CX-3543. Doses have been well tolerated. Seven grade 3 adverse events have been reported during the study, but none of these are related to CX-3543. To date no objective responses have been observed. One patient with advanced refractory prostate cancer has stable disease of longer than 4 months duration. CX-3543 has demonstrated good linearity in PK parameters between the dose cohorts with a terminal half life of approximately 12 hours following the first dose. Conclusions: To date, CX-3543 has shown no drug related toxicity and has predictable PKs. No DLTs have yet been observed, and the MTD remains to be defined in this Phase I study. Further enrollment to the planned dose escalation cohorts is ongoing. [Table: see text]

3593 Background: BAY 73–4506 is a multikinase inhibitor targeting both the tumor and its vasculature. BAY 73–4506 inhibits VEGFR-2 and -3, and tumor cell signaling kinases (RET, KIT, PDGFR, and Raf). This drug shows potent, oral activity in a wide variety of preclinical xenograft models. Methods: This phase I dose-escalation trial investigated the safety, pharmacokinetic (PK), and pharmacodynamic (PD) profile of BAY 73–4506 given orally in 21 days on/7 days off cycles, until discontinuation due to toxicity or tumor progression. PK was assessed on days 1 and 21 of cycle 1. PD markers included dynamic contrast-enhanced MRI (DCE-MRI) and circulating sVEGFR-2 and VEGF levels assessed at each cycle. Tumor response was evaluated per RECIST criteria. Results: 22 patients (pts) with documented progressive disease were enrolled at doses of 10 mg to 120 mg once daily. Tumor types included CRC (27%), RCC (18%) and pancreatic cancer (14%). Pts had received a median of 3 prior therapies, including anti-VEGF agents in 5 pts. BAY 73–4506 PK appeared linear with dose; the AUC target exposure level of 13 mg*h/L (from preclinical models) was reached at 30 mg. The major metabolite of BAY 73–4506 (active in vitro) reached a similar AUC(0–24)ss as the parent drug at 120 mg. Commonly reported drug-related adverse events (=10% of pts) were hoarseness (7 [32%], all CTC grade 1), hypertension (5 [23%], all CTC grade 1–2), fatigue (3 [14%], CTC grade 3 in 1 pt [5%]), hand-foot-skin reaction (HFSR) (3 [14%], CTC grade 3 in 1 pt [5%], mucositis (3 [14%], all CTC grade 1). Maximum tolerated dose was exceeded at 120 mg with dose-limiting toxicities including fever without documented infection, HFSR, fatigue, and leukopenia. 2 pts (RCC & osteosarcoma) achieved RECIST partial response. 4 pts had stable disease, one of them a cervical cancer pt with extensive tumor cavitation. PD parameters (decrease in sVEGFR-2 levels, decrease in iAUC60s of Gd-DTPA by DCE-MRI) correlated with drug exposure. Conclusions: BAY 73–4506 was well tolerated at 60 mg with report of dose-limiting toxicities at 120 mg. 6 (28%) of 22 pts demonstrated antitumor activity. Optimal dose and regimen are under evaluation in preparation for phase II trials. No significant financial relationships to disclose.

7569 Background: We conducted a phase I/II study of combination chemotherapy with nedaplatin (CDGP) and amrubicin (Amr) for patients with untreated, advanced non small-cell lung cancer (NSCLC). Methods: Eligible patients were having adequate organ function and PS of 0-1. CDGP was given on day 1 and amrubicin on days 1, 2 and 3. The treatment was repeated every 3 weeks. We fixed the dose of CDGP as 100 mg/m2, and escalated the dose of amrubicin from a starting dose of 25 mg/m2 by 5mg/m2 per each levels until the maximum tolerated dose (MTD). The MTD was defined as the dose level at which at least two of three or two of six patients experienced a dose-limiting toxicity (DLT). Results: Between June 2009 and May 2011, 36 patients were enrolled. In the phase I study, two DLTs occurred in six patients at level 2; dose level 1 was therefore recommended (25 mg/m2 Amr, 100mg/m2 CDGP). DLTs included cerebral infarction and grade 4 thrombocytopenia. In the phase II study, including phase I study, a total of 36 patients were enrolled and 132 cycles of chemotherapy were conducted. Grade 3 or 4 neutropenia, grade 3 anemia and grade 3 or 4 thrombocytopenia occurred in 75%, 16.6% and 19.4% in all cycles, respectively. Febrile neutropenia occurred in 4cycles (3%) but all of them were controllable. Eighteen patients achieved a partial response and the overall response rate was 51.4%. Conclusions: Combination of CDGP and Amr was highly effective and well tolerable in patients with untreated, advanced NSCLC.

2544 Background: C-Met protein is a receptor tyrosine kinase which is overexpressed or mutated in a variety of tumor types, causing cell proliferation, metastasis, and angiogenesis. Tivantinib is an orally bioavailable small molecule which binds to the c-Met protein. This phase I study was designed to determine the maximum tolerated dose (MTD) of tivantinib in combination with standard dose FOLFOX for the treatment of patients with advanced solid tumors. Methods: Patients with advanced solid tumors for which FOLFOX (5-FU IV 400 mg/m2 day 1; 5-FU CIV 2400 mg/m2 day 1; Leucovorin IV 400 mg/m2 day 1; Oxaliplatin IV 85 mg/m2 day 1) would be appropriate chemotherapy received escalating doses of tivantinib BID (days 1-14) in a standard 3 + 3 design. Dose-limiting toxicities (DLTs), non-dose-limiting toxicities (NDLTs), safety, and preliminary efficacy were evaluated. Results: Fourteen patients (50% colorectal) were treated across 3 dose levels: 120 mg (n=3); 240 mg (n=5); 360 mg (n=6). No DLTs were observed until the 3rd dose level (treatment delay ≥3 days, secondary to grade 3 neutropenia). Common related adverse events (% grade 1/2; % grade 3/4) included: diarrhea (36%; 0%), neutropenia (0%; 29%), nausea (14%; 14%), vomiting (14%; 14%), dehydration (14%; 7%), and thrombocytopenia (14%; 0%). To date, 7 patients have been evaluated for response including 4 (57%) with stable disease evident at the 8-week evaluation (CRC, 2 patients; unknown primary favoring CRC, 1 patient; esophageal, 1 patient) and 3 (21%) with disease progression. The 4 patients with stable disease are continuing on treatment; three (CRC and unknown primary) had received prior FOLFOX. Conclusions: The addition of tivantinib to standard therapy FOLFOX appears tolerated up to its recommended phase II monotherapy dose of 360 mg. Preliminary efficacy is encouraging, and a phase II study is proceeding with this regimen for the first line treatment of advanced gastroesophageal patients. Clinical trial information: NCT01611857.
