11070 Background: Pazopanib is a tyrosine kinase inhibitor approved globally for advanced soft tissue sarcomas. The dose finding phase of this cooperative group trial assessed the dose limiting toxicities (DLT) and the maximally tolerated dose (MTD) of adding pazopanib to neoadjuvant chemoradiation or radiation therapy in children and adults with unresected intermediate/high-risk trunk and extremity non-rhabdomyosarcoma soft tissue sarcomas (NRSTS). Methods: ARST1321, a jointly designed intergroup study lead by Children's Oncology Group and NRG Oncology opened for enrollment in July 2014. Eligible adult and pediatric patients with newly diagnosed, unresected trunk/extremity NRSTS with plans for primary tumor resection were enrolled into either the Chemotherapy Cohort (those with chemosensitive NRSTS > 5 cm, grade 3, including all synovial sarcoma) or the Non-Chemotherapy Cohort (those with chemotherapy insensitive NRSTS of any size, grade 2/3, or any chemosensitive NRSTS for whom no chemotherapy was planned per discretion of patients and treatment teams). In the Chemotherapy Cohort, pazopanib was given with ifosfamide (7.5 grams/m2) and doxorubicin (75 mg/m2) plus 45 Gy preoperative RT starting after cycle 2. Primary tumor was resected at week 13, followed by chemotherapy and pazopanib to week 25. In the Non-Chemotherapy Cohort, pazopanib was given with 50 Gy preoperative RT, primary tumor was resected at week 10, and pazopanib continued to week 25. Feasibility was assessed through week 6 of therapy to determine pazopanib dose escalation/de-escalation based on DLT, total doses of pazopanib, and overall adverse event profile. Results: In the Chemotherapy Cohort, MTD was reached at Dose Level 1 (350 mg/m2 peds; 600 mg adults) with two DLTs (1 grade 3 ALT rise, 1 intolerability to therapy) in 10 patients. In the Non-Chemotherapy Cohort, 11 patients enrolled at Dose Level 1 (350 mg/m2 peds; 600 mg adults) without any observed DLTs and all received ≥75% of prescribed total pazopanib dose; MTD was reached at Dose Level 2 (450 mg/m2 peds; 800 mg adults) with 2 DLTs in ten patients enrolled (1 grade 3 dermatitis and 1 intolerability to therapy) and 9/10 receiving ≥75% of full dose. Conclusions: Pazopanib in combination with chemoradiation or radiation therapy alone was found to be safe in children and adults with NRSTS. Following this finding, ARST1321 opened in both arms using the newly determined pazopanib MTDs. Clinical trial information: NCT02180867.

4559 Background: We conducted a phase I dose-finding study of sorafenib (S) in combination with capecitabine (X) and cisplatin (P) in patients with previously untreated metastatic or inoperable advanced gastric cancer. Methods: Four dose levels of S, X, and P combination were tested. The doses of S (p.o. daily), X (p.o. on days 1–14), and P (i.v. on day 1) were escalated at the following schedule; level 1: S 400 mg/d, X 1,600 mg/m2/d, P 80 mg/m2; level 2: S 800 mg/d, X 1,600 mg/m2/d, P 80 mg/m2; level 3: S 800 mg/d, X 2,000 mg/m2/d, P 80 mg/m2; level 1A: S 800 mg/d, X 1,600 mg/m2/d, P 60 mg/m2. The cycle was repeated every 3 weeks. Dose limiting toxicities (DLTs) were evaluated only in the first cycles and a standard 3+3 dose escalation design was implemented. Results: A total 21 pts were enrolled in the study. No DLTs were observed at dose level 1 (n=3). One DLT (grade 3 diarrhea) was noted at dose level 2 (n=6), and 2 DLTs (two grade 4 neutropenias longer than 5 days in duration) were observed at dose level 3 (n=6), which made the level 3 dose the maximum tolerated dose (MTD). However, at cycle 2 and thereafter at dose level 2, the relative dose intensity (RDI) of S and X could not be maintained (mostly below 80%) due to the frequent dose reductions and cycle delays. So, we explored a new dose level (1A) between dose level 1 and 2. Since no DLTs were found in 6 patients at level 1A with RDI mostly above 80% throughout the treatment period, level 1A was determined as recommended dose (RD). Most frequent grade 3 and 4 hematologic toxicities were neutropenia (25.0% of cycles), and most frequent grade 2 and 3 non-hematologic toxicities were hand-foot syndrome (9.4%), asthenia (7.0%), and anorexia (5.5%). The objective responses were confirmed in 10 out of 16 patients with measurable lesions (62.5%; 95% CI, 38.8–86.2%). With a median follow-up of 8.1 months, estimated median progression-free survival was 10.0 months (95% CI, 1.6–18.4 months) and median overall survival has not been reached. Conclusions: Diarrhea and neutropenia were DLTs in this S, X, and P combination. The dose schedule of sorafenib 400 mg po bid daily with capecitabine 800 mg/m2 po bid on days 1–14, and cisplatin 60 mg/m2 iv on day 1 in every 3 weeks is recommended for further development in AGC.

e14506 Background: The mammalian target of rapamycin (mTOR) is a key downstream protein activated via PI3K-AKT pathway, and regulates cell growth, proliferation, and survival. Inhibition of mTOR in addition to EGFR may overcome upstream resistance to EGFR inhibitors in CRC. This is a phase Ib study to determine the maximum tolerated dose (MTD) of the PIE combination. Methods: Patients with KRAS WT mCRC following failure of first line fluoropyrimidine based therapy received IV irinotecan and panitumumab every 2 weeks, and everolimus orally throughout a 14 day cycle. Dose finding used a standard 3+3 design with the MTD defined as the dose with dose limiting toxicity (DLT) in ≤1/6 patients. A DLT is any of the following in the first 28 days; febrile neutropenia, G3/G4 neutropenia > 14 days, any G4 thrombocytopenia, any non-haematologic event of G4 or of G3 for >7 days, treatment delays of >14 days. Dose level 1; irinotecan 200mg/m2, panitumumab 6mg/kg, everolimus 5mg alternate days. Dose level 2; irinotecan 200mg/m2, panitumumab 6mg/kg, and everolimus 5mg daily. Results: 15 patients have been enrolled into the study, 2 withdrew prior to receiving any therapy. Five patients were enrolled at dose level 1. Two patients were not evaluable. Of the three evaluable patients there was no DLT. Three patients were then treated at dose level 2. Following one DLT (grade 3 mucositis >7 days), the cohort was expanded to 5 evaluable patients but suspended after a further DLT (grade 3 mucositis > 7 days). Other grade 3 toxicities were anorexia, rash, vomiting, and hypersensitivity. There were no grade 4 toxicities. Dose level 1 was expanded by 3, to a total of 6 evaluable patients. Grade 3 toxicities were mucositis (17%), fatigue (17%), diarrhoea (33%), rash (17%), hypomagnesemia (17%), and neutropenia (17%). There was no DLT. Conclusions: Dose level 2 exceeded the MTD. Dose level 1 appears tolerable and warrants further investigation. The phase II component of the study is ongoing. Clinical trial information: NCT01139138.

Purpose We report on feasibility of preoperative chemotherapy with or without radiation therapy (RT) in the context of a phase III randomized clinical trial involving localized, high-risk, soft tissue sarcomas. Patients and Methods Of 321 eligible patients, 161 were randomly assigned to three preoperative cycles of epirubicin 120 mg/m2 plus ifosfamide 9 g/m2, and 160 were randomly assigned to three preoperative plus two postoperative cycles. Among them, 303 patients were included in this analysis; 169 were male and 134 were female, with a median age of 48 years (range, 15 to 79 years). One hundred fifty-two patients received concurrent RT preoperatively at a total dose of 44 to 50 Gy. Preoperative chemotherapy-related hematologic toxicity and early postoperative complications were reported. The influence of RT, age, and sex on hematologic grade 3 or 4 toxicities and wound complications was analyzed. Chemotherapeutic dose intensity (DI) was analyzed. Results Among the patients, 61.4%, 22.4%, and 23.8% experienced, grade 4 leucopenia, grade 3 or 4 anemia, and grade 3 or 4 thrombocytopenia, respectively. Respective rates were 66.4%, 24.3%, and 31.6% when RT was added preoperatively, and 56.3%, 20.5%, and 15.9% when preoperative chemotherapy was administered alone. Patient age affected grade 3 or 4 thrombocytopenia. Grade 4 leucopenia and grade 3 or 4 anemia presented 2.5 times more frequently in female patients than in male patients. Wound complications were observed in 13.5% of patients: 17% with preoperative RT and 10% without. Chemotherapeutic DI was greater than 90%, even in patients receiving preoperative RT and in patients age 65 years or older. Conclusion This preoperative chemotherapy is feasible and can also be proposed for selected elderly patients. Grade 3 or 4 hematologic toxicity was common, but DI was excellent. Concurrent preoperative RT is safe, although an increased rate of grade 4 thrombocytopenia and limited increase in wound complications may be observed.

337 Background: Little evidence exists on 2nd line therapy for gemcitabine resistant patients. The combination of oxaliplatin (Ox) and 5-FU has shown efficacy in small trials. We wanted to establish a tolerable dose of the combination of irinotecan, cetuximab and everolimus(ICE), and test it vs. the combination of capecitabine (Cap) and Ox in a randomized phase I/II setting. Methods: Patients were initially recruited in a 3+3 dose finding design with an expanded MDT cohort. After establishing MDT; patients were randomized between ICE (at MDT-1) and CapOx (Cap: 1250 mg/m2 BID and Ox: 70 mg/m2q14d). Patients that progressed could cross-over to the other arm. (NCT01042028). Results: Between January 2010 and November 2012, 40 patients were recruited. Due to DLT toxicity (mainly mucositis) at dose level 1 of the phase I trial, the protocol was amended and patients were treated at dose level -1. Ten patients were safely treated at this dose. The final dose for everolimus was 2.5 mg q1d, for irinotecan 180 mg/m2 q14d and 500 mg/m2q14d for cetuximab. At this dose level patients were randomized to either ICE or CapOx. Planned accrual was 90 patients, but due to the emergence of FOLFIRINOX and slow accrual, the study was terminated after randomization of 26 patients. One patient died before randomization. Median PFS for the ICE regime was 3.8 months (2.5-7.8), CapOx 3.5 (1.7-5.3) p=0.72. Median OS for ICE was 7.7 (4.5-11.8) and for CapOx 4.5 (2.2-7.4) p=0.04. Six patients crossed from CapOx to ICE, and 3 patients from ICE to CapOx upon progression. RR for ICE was 25% (5-57), CapOx 29% (8-58). Toxicity grade 3+ in the ICE regime was acne-like-rash (20%), fatigue (16%), infection (16%) and emboli (12%). CapOx was associated with grade 3+ neuropathy (21%), emboli (14%), pain (21%) and PPE (14%). Conclusions: The triple combination of ICE displayed similar PFS but significantly increased OS compared to CapOx. Both regimes displayed cancer activity with acceptable response rates. Toxicity was manageable. Due to early termination no solid conclusions can be drawn. Selected patients may benefit from dual-targeted therapy. Clinical trial information: NCT01042028.

Global Quality Of Life

We have documented functional and psychosocial changes in patients with extremity soft tissue sarcomas who have undergone multimodality limb-sparing treatments. In 88 patients, parameters related to economic status, sexual activity, pain, limb function, and global quality of life (QOL) were recorded prior to surgery and every 6 months postoperatively. Changes from the preoperative assessment for every parameter were analyzed in each patient. Six months after surgery, there was a decrease in employment status, sexual activity, and in limb function in a significant number of patients. At 12 months, these decreases were still evident. Despite these changes, global QOL measured by a standardized test showed at least some improvement in a significant proportion of patients at 12 months. These findings highlight the difficulty in defining QOL. It could not be ascertained if radiation therapy and/or chemotherapy were causative factors in specific changes because of the small numbers of patients in each subgroup. However, among 60 patients with high-grade sarcomas, significant wound problems developed in 10 of 33 who received postoperative radiation therapy in combination with adjuvant doxorubicin and cyclophosphamide chemotherapy compared with one of 27 patients who received adjuvant chemotherapy alone (P = .016). Also, among high-grade sarcoma patients with 12-month follow-up, six of 19 patients who received radiation therapy and chemotherapy developed joint contractures compared with zero of 15 patients who received chemotherapy alone (P less than .04). The combination of postoperative radiation therapy and chemotherapy appeared to be associated with significantly more tissue-related injury in patients with high-grade sarcomas compared with chemotherapy alone.
