Purpose This phase I trial was conducted to determine the safety, tolerability, pharmacokinetics, and pharmacodynamics of deforolimus (previously known as AP23573; MK-8669), a nonprodrug rapamycin analog, in patients with advanced solid malignancies. Patients and Methods Patients were treated using an accelerated titration design with sequential escalating flat doses of deforolimus administered as a 30-minute intravenous infusion once daily for 5 consecutive days every 2 weeks (QD×5) in a 28-day cycle. Safety, pharmacokinetic, pharmacodynamic, and tumor response assessments were performed. Results Thirty-two patients received at least one dose of deforolimus (3 to 28 mg/d). Three dose-limiting toxicity events of grade 3 mouth sores were reported. The maximum-tolerated dose (MTD) was 18.75 mg/d. Common treatment-related adverse events included reversible mouth sores and rash. Whole-blood clearance increased with dose. Pharmacodynamic analyses demonstrated mammalian target of rapamycin inhibition at all dose levels. Four patients (one each with non–small-cell lung cancer, mixed müllerian tumor [carcinosarcoma], renal cell carcinoma, and Ewing sarcoma) experienced confirmed partial responses, and three additional patients had minor tumor regressions. Conclusion The MTD of this phase I trial using an accelerated titration design was determined to be 18.75 mg/d. Deforolimus was well tolerated and showed encouraging antitumor activity across a broad range of malignancies when administered intravenously on the QD×5 schedule. On the basis of these overall results, a dose of 12.5 mg/d is being evaluated in phase II trials.

PURPOSE: This phase I trial sought to evaluate the toxicity of and determine the maximum-tolerated dose (MTD) for the two-drug regimen doxorubicin and gemcitabine (AG) followed by the three-drug regimen of ifosfamide, paclitaxel, and cisplatin (ITP) in patients with unresectable or metastatic transitional-cell carcinoma. PATIENTS AND METHODS: Patients received AG every other week for six cycles followed by ITP every 3 weeks for four cycles. Five AG dose levels were investigated, up to doxorubicin 50 mg/m2 and gemcitabine 2,000 mg/m2, to determine the MTD of the regimen. The dose and schedule of ITP were constant: ifosfamide 1,500 mg/m2 (days 1 to 3); paclitaxel 200 mg/m2 (day 1); and cisplatin 70 mg/m2 (day 1). Granulocyte colony-stimulating factor was given between all cycles of therapy. RESULTS: Fifteen patients enrolled onto this phase I trial. AG was well tolerated at all dose levels, with no grade 3 or 4 myelosuppression. Toxicity experienced with ITP included grade 3 and 4 granulocytopenia in four patients and grade 3 nausea/vomiting in three patients. No grade 3 and 4 neurotoxicity was observed. Eight of 14 assessable patients experienced a major response to AG, including five of six patients treated at the two highest AG dose levels. After completion of AG-ITP, nine of 14 assessable patients had a major response (three complete responses and six partial responses). CONCLUSION: AG is a well-tolerated and active regimen. Sequential chemotherapy with AG-ITP is also well tolerated, and phase II investigation at the highest dose level is ongoing.

e13104 Background: The aim of this study was to determine the maximum tolerated dose (MTD) and recommended dose of docetaxel-PNP when administered every 3 weeks in patients with advanced solid malignancies. Methods: Three to six patients received docetaxel at dose levels of 20-75 mg/m2 as 60-min infusions every 3 weeks according to the single dose-escalating 3+3 method. Blood samples at the first dose of docetaxel-PNP were collected for PK analysis. Results: Nineteen pts were treated for a median of two cycles (1-14) in the phase I study. Dose escalation was performed up to 75 mg/m2. The most frequently reported adverse events were grade 4 neutropenia (52.6%, 10/19), grade 1 myalgia (42.1%, 8/19) and grade 1 alopecia (42.1%, 8/19). No acute infusion reactions were noted. Two dose-limiting toxicity was observed at 20 and 60 mg/m2, which were grade 3 hypophosphatemia and death of unknown cause, respectively. Although the MTD was not determined, the recommended dose was determined as 60 mg/m2. This was based on neutropenia and PK parameters which are summarized in the table. PK parameters revealed dose linearity. Partial response was seen in one patient and stable disease in seven patients. Conclusions: Administration of docetaxel-PNP was well tolerated up to 60 mg/m2 every 3 weeks by heavily pretreated patients. Further phase II trials are recommended at this dose level.

1563 Background: Reovirus is an oncolytic virus which replicates preferentially in transformed cells possessing activated Ras signaling pathways. Promising activity was found in in vivo models of MGs and in a phase I trial in patients (pts.) with cutaneous metastases from systemic cancer. We performed this dose-escalation trial of i.t. administration of reovirus to determine the dose limiting toxicity (DLT) and maximum tolerated dose (MTD) in pts. with recurrent MG. Response, survival and time to progression (TTP) were secondary aims. Methods: Pts. were ≥ 18 yrs old, had a KPS ≥ 60, received prior radiotherapy ± chemotherapy, a histologically proven recurrence of MG and recurred ≤ 3 times. Reovirus was administered i.t. stereotactically at one of three dose levels (1 × 107, 1 × 108 or 1 × 109 TCID50) in a volume of 0.9 mls. Results: Twelve pts. were treated at 3 dose levels; seven were men, the median (mdn) KPS was 80, mdn age was 53.5 yrs, 10 had glioblastoma multiforme, one anaplastic astrocytoma and another anaplastic oligoastrocytoma. There were the 1st, 2nd or 3rd recurrences in 6, 5 and 1 pts., respectively. During i.t. viral administration all pts. were treated with prophylactic anticonvulsants and 6 (50%) were receiving corticosteroids. The 1st, 2nd and 3rd cohorts contained 3, 6 and 3 pts., respectively. There were no grade 3 or 4 adverse events definitely or probably related to the administration of reovirus. A transient increase in GGT was possibly related to reovirus administration and a patient experienced grade 3 motor weakness that could be related to post-injection edema. Viral shedding and systemic immune responses were examined but results are pending. There were no CR, or PR; a pt. had SD, 10 PD and one was not evaluable. The mdn survival was 20 weeks (range, 6–171), 6 pts. survived > 6 months and 3 are alive 6, 7 and 40 months from the reovirus injection. The mdn TTP was 4.3 weeks (range: 3.4–39). Conclusions: A MTD was not reached. The intratumoral administration or reovirus was well tolerated in patients with recurrent MGs. Phase 2 studies in MGs are planned. [Table: see text]

5099 Background: Bevacizumab, an intravenous monoclonal antibody against VEGF, and sunitinib, an oral multi-targeted tyrosine kinase inhibitor of VEGF and PDGF receptors, both have activity in mRCC [NEJM 349:427–434; JAMA 295:2516–2524]. Combining bevacizumab and sunitinib may increase antitumor efficacy by maximizing inhibition of the VEGF pathway. The safety and maximum tolerated dose (MTD) of sunitinib in combination with bevacizumab was assessed in this Phase I trial. Methods: Cohorts of 3–6 pts with mRCC received escalating doses of sunitinib (dose levels: 25, 37.5, and 50 mg po) daily for 4 weeks (wks) followed by 2 wks off with fixed- dose bevacizumab (10 mg/kg iv) every 2 wks continuously. Pre-determined dose-limiting toxicities (DLTs) in the first 6-wk cycle included Grade (Gr) 4 neutropenia, ≥Gr 3 thrombocytopenia of ≥7 days, Gr 4 hypertension or proteinuria, and other Gr 3 non-hematologic toxicity of ≥7 days. Pts who came off study prior to completion of cycle 1 for any reason other than a DLT were replaced. Serum VEGF levels were measured before and during cycles 1 and 2. Results: 16 pts (11 male, 5 female, median age 57) were enrolled. Of 8 patients entered at the first dose level (sunitinib 25 mg, bevacizumab 10 mg/kg), 2 were replaced; 1 never received treatment and 1 did not complete cycle 1 due to rapid progression of disease (PD). No DLTs occurred in the remaining 6 evaluable pts in this cohort. At the 2nd dose level (n =6, sunitinib 37.5 mg, bevacizumab 10 mg/kg), 1 pt receiving low molecular weight heparin had a DLT of Gr 4 hemorrhage. 2 pts have enrolled in the 3rd dose level (sunitinib 50 mg, bevacizumab 10 mg/kg) but are not yet evaluable for toxicity or response. Gr 3/4 toxicities over all cycles included Gr 3 hypertension (n=4), Gr 3 proteinuria (n=2), Gr 3 abdominal pain (n=2), Gr 4 hemorrhage (n=1), and Gr 3 hand/foot syndrome (n=1). 13 pts were evaluated for best response–4 had partial responses, 7 had stable disease, and 2 had PD. Serum VEGF levels decreased during cycle 1 in all pts. Conclusions: The combination of sunitinib and bevacizumab in mRCC pts was tolerable at the first 2 dose levels. Once the MTD is identified, further testing of this combination in phase II trials may be indicated for mRCC as well as other malignancies. [Table: see text]

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]

PurposeThe objectives of this phase I trial were to determine the maximum-tolerated dose (MTD), toxicity profile, dose-limiting toxicities (DLTs), pharmacokinetics, and preliminary response rate for ixabepilone, a microtubule-stabilizing agent, administered intravenously daily for 5 days in children and adolescents.Patients and MethodsPatients ≥ 2 and ≤ 18 years with relapsed or refractory solid tumors were enrolled onto sequential cohorts to the following five dose levels: 3.0 (n = 3), 4.5 (n = 4), 6.0 (n = 3), 8.0 (n = 6), and 10 (n = 3) mg/m2/d. Eligibility criteria, dose levels, definitions of DLT and MTD, and pharmacokinetic sampling times were designed to be as similar as possible to the adult phase I trial of ixabepilone on the same schedule.ResultsNineteen children (median age, 10 years; range, 2 to 18 years) were enrolled, and 18 (12 with sarcomas) were assessable for toxicity. DLTs (grade 4 neutropenia for > 5 days and grade 3 fatigue) were observed in two of three patients receiving 10 mg/m2/d. The MTD of ixabepilone administered daily for 5 days every 21 days was 8 mg/m2/d. Myelosuppression, GI, and hepatic toxicities were common non-DLTs. Peripheral neuropathy was uncommon. Ixabepilone clearance was 475 ± 247 mL/min/m2, volume of distribution at steady-state was 12.2 ± 5.4 L/kg, and half-life was 14 hours.ConclusionThe recommended dose of ixabepilone for phase II trials in solid tumors is 8 mg/m2/d daily for 5 days every 21 days. This dose is 33% higher than the MTD in adults receiving the same dosing schedule. Pharmacokinetic parameters in children and adolescents were highly variable but similar to adults.

PURPOSE A phase I trial was undertaken because interleukin-1 alpha (IL-1 alpha) possesses antiproliferative, immunostimulatory, antiinfection, myeloprotective, and myelorestorative properties that could be beneficial in cancer treatment. PATIENTS AND METHODS In this phase I trial, IL-1 alpha was administered intravenously (IV) during a 15-minute period daily for 7 days to patients with advanced solid malignancies. RESULTS The maximum-tolerated dose (MTD) of IL-1 alpha alone was 0.3 microgram/kg. A second group of patients received indomethacin plus IL-1 alpha based on preclinical studies, which indicated that indomethacin could abrogate IL-1 alpha-induced hypotension; however, the MTD of IL-1 alpha plus indomethacin was 0.1 microgram/kg lower than IL-1 alpha alone. Fever, chills, headache, nausea, vomiting, and myalgia were common but were not dose-limiting. Hypotension resulted from a marked decrease in systemic vascular resistance and required pressors at 0.3 and 1.0 micrograms/kg IL-1 alpha. Dose-limiting toxicities included hypotension, myocardial infarction, confusion, severe abdominal pain, and renal insufficiency. IL-1 alpha treatment caused a significant, dose-related increase in the total WBC count (mainly segmented neutrophils and neutrophilic bands). Bone marrow cellularity increased because of enhanced numbers of relatively mature myeloid cells and megakaryocytes. Platelet counts decreased during therapy but were significantly elevated above baseline values 1 to 2 weeks posttreatment; this may have been an effect of IL-6 that was shown to be induced by IL-1 alpha treatment. Significant increases in triglycerides, cortisol, C-reactive protein, thyroid-stimulating hormone and decreases in cholesterol, testosterone, and protein-C were observed with treatment. CONCLUSION We conclude that at doses of IL-1 alpha that can be given safely to cancer patients, significant, potentially beneficial hematopoietic effects occur.

PURPOSE Based on preclinical evidence in murine models that interleukin-6 (IL-6) mediates regression of metastatic tumors, we performed a phase I study of recombinant human IL-6 in patients with refractory advanced malignancies to determine its pharmacokinetics, toxicities, and possible immunologic and antitumor effects. PATIENTS AND METHODS Recombinant IL-6 was administered as a single subcutaneous dose daily for 7 days, with 7 days off therapy followed by another 7 days of IL-6. Doses were escalated in cohorts of three patients starting at 3 micrograms/kg/d, provided that toxicity at the preceding dose level was not dose-limiting. Dose-limiting toxicity was defined as grade III or IV major organ toxicity that did not resolve to grade II or less in 24 hours after stopping IL-6, using the National Cancer Institute Common Toxicity Criteria. Patients were treated with 3, 10, and 30 micrograms/kg/d IL-6 subcutaneously. RESULTS Three patients each were treated at the 3- and 10-micrograms dose levels. Two of five patients treated with 30 micrograms/kg/d IL-6 subcutaneously had grade III major organ toxicity that required IL-6 therapy to be discontinued. All patients experienced fever, chills, and minor fatigue. Significant increases in C-reactive protein (CRP), fibrinogen, platelet counts, and lymphocyte IL-2 receptor levels were seen in patients at the 10- and 30-micrograms/kg dose levels. Decreases in albumin and hemoglobin were observed, particularly at the 30-micrograms/kg dose level. The half-life (T1/2 beta) was 4.2 hours, with a peak IL-6 level at 5 hours. No antitumor responses were seen. CONCLUSION A safely tolerated dose of daily subcutaneous IL-6 is 10 micrograms/kg, with hepatotoxicity and cardiac arrhythmia being the dose-limiting toxicities at 30 micrograms/kg. Phase II trials of IL-6 administered subcutaneously daily for at least 7 days for two cycles with an intervening week of rest are recommended for phase II trials. However, patients with extensive replacement of liver by tumor and abnormal liver functions should receive IL-6 therapy with caution.
