TPS3636 Background: Colorectal cancer (CRC) is the second leading cause of cancer-related death in western countries. With advances in the treatment of metastatic CRC (mCRC) in the last decade using combination chemotherapy and bevacizumab, a monoclonal antibody against the vascular endothelial growth factor (VEGF), progression free survival (PFS) in first and second line setting was substantially improved. Tumour angiogenesis is also driven by other factors but VEGF including Platelet Derived Growth Factor (PDGF) and Fibroblast Growth Factor (FGF). BIBF1120 is a potent, orally available triple angiokinase inhibitor that blocks the receptor tyrosine kinase activity of human VEGFR1-3, FGFR1 and -3 and PDGFRα and -β. Thus, BIBF1120 could be an exciting addition to the treatment of patients with chemorefractory CRC. Methods: Randomized, double-blind, placebo-controlled, multicentre, phase II trial of BIBF1120 (orally, 200 mg, bid, d1-d14, Arm A) vs. placebo (Arm B) in patients receiving mFOLFOX6 (oxaliplatin, 85 mg/m2, fluorouracil, 400 mg/m2 bolus and 2400 mg/m2 over 46 h, leucovorin, 200 mg/m2) q14 d for patients (ECOG performance status 0-1) with chemorefractory mCRC who received one prior line of chemotherapy. Scheduled are 90 patients per treatment arm. Primary endpoint: PFS, Secondary endpoints: objective response, overall survival, duration of overall response, safety. Additionally there will be an explorative analysis of predictive biomarkers for BIBF1120. 4 of planned 180 patients have been enrolled. We expect the last patient out in June 2013.

PURPOSE: To study tolerability and efficacy of an intensified chronomodulated schedule of fluorouracil (5-FU) and l-folinic acid (l-FA) as first-line treatment of metastatic colorectal cancer, 5-FU was given near individually determined dose-limiting toxicity in a multicenter phase II trial. PATIENTS AND METHODS: One hundred patients (68 men and 32 women, median age 62 years, World Health Organization performance status ≤ 2) with previously untreated and inoperable metastases received chronomodulated daily infusion of 5-FU/l-FA (from 10:00 pm to 10:00 am with peak at 4:00 am). 5-FU dose was escalated from 900 to 1,100 mg/m2/d with fixed dose of l-FA at 150 mg/m2/d for 4 days every 14 days. RESULTS: 5-FU dose escalation was achieved in 66% of the patients. Grade 3 to 4 toxicities mainly consisted of nausea or vomiting (14% of patients and 1.5% of courses), hand-foot syndrome (38% of patients and 8% of courses), mucositis (26% of patients and 4% of courses), and diarrhea (21% of patients and 2.3% of courses). Objective response rate (ORR) was 41% (95% confidence interval, 31.5% to 50.5%). Twenty patients underwent metastases surgery; among these, 12 had a complete resection. Median progression-free survival was 7 months. Median survival was 17 months; 28% of the patients were alive at 2 years and 18.6% at 3 years. CONCLUSION: The ORR achieved with intensified chronomodulated delivery of 5-FU/l-FA was nearly twice as high as that earlier obtained by our cooperative group using less intensive 5-FU/FA chronotherapy.

5018 Background: The epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) are commonly over-expressed in OC and correlate with poor prognosis. The anti-VEGF antibody B and the EGFR tyrosine kinase inhibitor E have each demonstrated activity in OC. Dual inhibition with BE may overcome mechanisms of resistance encountered with either agent alone. Methods: We are conducting a 2-stage phase II trial of BE in pts with recurrent OC, primary peritoneal, and FT cancer. Eligible pts had ≤ 2 prior chemo regimens for recurrent or refractory disease; no prior VEGF or EGFR inhibitors; ECOG performance status (PS) 0–2; measurable disease; normal organ function; no proteinuria (<1000 mg/24 hours). B 15 mg/kg was given IV on day 1 every 21 days and daily E 150 mg PO was given continuously. CT scans were obtained every 9 weeks. 2 responses are required in the first stage to justify accrual into a second stage. Results: 13 pts enrolled at 3 centers from 7/05 to 10/05. Median age: 56 (range 45–70). PS (N with 0/1/2): 6/4/3. Primary site (N): OC 11, FT 2. Primary platinum response (N): refractory 4, resistant (<12 mo PFS) 2, sensitive (≥12 mo) 7. Total prior chemo regimens (N with 1/2/3): 1/8/4. 55 cycles of BE have been delivered (median 4, range 1–8). 12 pts are evaluable for response (1 too early). There has been 1 major response (8%). 8 patients (67%) had stable disease (SD). 1 pt with SD met 75% CA-125 response criteria. 8 pts remain on study. Median PFS has not been reached (median f/u 2.2 months). Attributable toxicities (N with grade 1/2/3/4): rash 4/7/0/0, diarrhea 6/1/2/0, stomatitis 3/1/0/0, myalgias 4/0/0/0, proteinuria 3/0/0/0, bilirubin 0/2/0/0. There were 2 bowel perforations (grade 3/4): both had 2 prior regimens, peritoneal implants >1 cm, 3 doses of B (last was 10 and 42 days prior), and small bowel obstructions in the preceding 28 days. Conclusions: The first stage of accrual is complete and further enrollment is on hold pending continued efficacy evaluation. There appeared to be an increased rate of bowel perforation, and identification of potential risk factors for this event would be critical for further development of this combination. Updated results will be presented. Supported by NCI Grant N01-CM-17102. [Table: see text]

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.

The Impact

TPS3635^ Background: The identification of prognostic and predictive biomarkers could significantly improve the risk-benefit ratio and cost-effectiveness of 1st-line mCRC regimens. This is the first prospective study of tumoral ERCC1 (chemo-resistance marker to platinum compounds) and plasma VEGF-A as potential biomarkers for oxaliplatin- and BV-containing regimens, respectively, in an effort to further define the optimal chemotherapy backbone with biologic therapies, including BV, for mCRC. Methods: In this randomized, open-label, global, phase II study, patients (N=360) with histologically or cytologically confirmed CRC and ≥1 measurable metastatic lesion are stratified at screening by tumoral ERCC1 mRNA expression (high vs low, cutoff of 1.7 [ERCC1/β-actin mRNA]). Eligibility criteria include completion of adjuvant therapy >12 months before screening and an ECOG performance status ≤1. Blood samples are collected to quantify plasma VEGF-A levels. Patients within each ERCC1 stratification group are randomized 1:1 to mFOLFOX6-BV or FOLFIRI-BV administered in 2-week cycles. BV will be given at a dose of 5 mg/kg IV q2w. Patients will remain on study treatment until disease progression (PD) or unacceptable toxicity. If oxaliplatin or irinotecan need to be discontinued, BV and 5-fluorouracil or capecitabine are to be continued until PD. The primary objectives are: 1) to assess ERCC1 and VEGF-A as biomarkers of progression-free survival (PFS) for oxaliplatin- and BV-containing regimens in 1st-line mCRC, and 2) within ERCC1 high patients, to test whether FOLFIRI-BV is associated with a prolonged 1st-line PFS compared to mFOLFOX6-BV. Secondary objectives include assessing the impact of these markers on overall survival, objective response, hepatic metastases resection, and safety. Exploratory endpoints include correlative analyses with additional tumor tissue, blood, and SNP markers. The first patient was enrolled in August 2011. An interim biomarker distribution assessment of the first 100 patients is planned, and the evaluation of the primary endpoints is estimated for early 2015. Clinicaltrials.gov: NCT01374425.

e17535 Background: Pathological complete response (pCR) with neoadjuvant chemotherapy is associated with improved survival in many solid tumors. We evaluated efficacy and tolerability of neoadjuvant plus adjuvant C+P in this phase II trial. Methods: We recruited patients (pts) with clinical stage IB-IIIA (TNM 7th ed) NSCLC, ECOG performance status (PS) 0-1 in this single-arm phase II trial using two-stage design with 90% power to detect pCR rate of >10% (vs null hypothesis of <2%). Pre-treatment mediastinal biopsy was required. Protocol was amended in 2009 to exclude squamous histology. Pts received 3 cycles of C 75mg/m2 + P 500mg/m2 (day 1 every 21 days) followed by surgical resection. Two cycles were delivered adjuvantly within 60-80 days after surgery. The primary end point was pCR. Secondary endpoints were objective response rate (ORR), overall survival (OS), disease-free survival (DFS), and adverse events (AEs). Results: 38 pts were enrolled with median age of 62 yrs, 19 males: 19 females. 74% (N=28) had ECOG PS 0. Preoperatively, 26% (N=10) had squamous histology, 29% (N=11) had biopsy-proven N2 involvement. Median of 4 cycles were administered. ORR was 29% (11 pts with PR). 4 pts did not undergo surgery (3 had disease progression; one became hypoxic during intubation in the OR). Resection status was R2 in 9% (3 of 34 pts), remaining pts had R0 resection. 6 pts had documented N2 clearance; median DFS (mDFS) and OS (mOS) of these pts have not reached (NR) vs 15 and 24 months respectively, in pts with persistent N2 disease. CTC grade 3+ nonhematologic AEs (<10%) include arterial thrombosis, bronchopleural fistula, empyema, hyperglycemia, fatigue and tinnitus. There was no pCR seen and thus accrual to 2nd stage was not pursued. There was no correlation between DFS or OS with ORR or pre-operative stage. There was statistically signification association between DFS with histology (favoring squamous, p=0.03) and post-op stage (p=0.024). The table shows mDFS and mOS in months according to pre-op stage. Conclusions: While the primary endpoint was not met, this regimen is active and well-tolerated perioperatively in NSCLC pts. [Table: see text]

TPS4148 Background: Tumors often consist of highly hypoxic subregions that are resistant to chemotherapy and radiotherapy. The investigational hypoxia-targeted drug TH-302 is reduced at its nitroimidazole group, and under hypoxic conditions releases the DNA alkylator bromo-isophosphoramide mustard (Br-IPM). A randomized Phase IIb trial of TH-302 in pts with metastatic or locally advanced unresectable pancreatic adenocarcinoma (PDAC) confirmed a significant PFS improvement (p=0.008) in pts treated with TH-302 at 340 mg/m2+ gemcitabine compared with gemcitabine alone (Borad et al, ESMO 2012). Skin and mucosal toxicities, mainly Grade 1/2, and myelosuppression (thrombocytopenia, neutropenia and anemia) were the most common AEs related to TH-302 and did not lead to increases in treatment discontinuation. Grade 3/4 myelosuppression was more frequent in the TH-302 + gemcitabine arm. AEs leading to treatment discontinuation as well as non-hematological serious AEs were balanced across arms. Methods: This is a Phase III, randomized, double-blind, placebo-controlled trial (NCT01746979) of gemcitabine + TH-302 compared with gemcitabine + placebo in pts with locally advanced unresectable or metastatic PDAC. The study is designed to detect a 25% risk reduction of death with 90% power and two-sided alpha of 5%. A total of 660 pts are planned to be randomized 1:1. Key eligibility criteria include histologically or cytologically confirmed disease, no prior chemotherapy or systemic therapy (except as specified in the protocol), ECOG performance status 0 – 1, and bilirubin ≤ 1.5x upper limit of normal. Randomized pts receive TH-302 + gemcitabine or gemcitabine + placebo in 4-week cycles until progressive disease, intolerable toxicity, or pt withdrawal. The primary objective is to evaluate OS. Secondary objectives include PFS, objective response, and disease control; safety and tolerability; pt-reported QoL and pain; CA 19-9 levels and PK of TH-302; exploratory pharmacogenomic markers and potential predictive biomarkers. Enrollment to the study is ongoing. Clinical trial information: NCT01746979.

BackgroundCombination chemotherapy is associated with improved outcomes in trials of selected fit patients with advanced colorectal cancer (acrc). For older or less-fit patients, combination chemotherapy is associated with greater toxicity and less benefit. Capecitabine monotherapy is a reasonable option for those patients, but the optimal dose remains controversial.MethodsA multicentre phase i/ii trial of reduced-dose capecitabine (2000 mg/m2, days 1–14 every 21 days) was conducted in 221 patients representing one or more of the following subsets: age greater than 65 years (n = 167), Eastern Cooperative Oncology Group (ecog) performance status of 1 or greater (n = 139), elevated lactate dehydrogenase (ldh) (n = 105), or prior pelvic radiation (n = 54). Based on phase i results, patients with prior pelvic radiation received capecitabine 750 mg/m2 twice daily. The goal was to ascertain efficacy in a design that was unlikely to cause high levels of toxicity.Results Median age in the patient cohort was 72 years. A median of 5 and a mean of 8 capecitabine cycles were given (range: 0–50 cycles). Grade 3 or 4 toxicity occurred in 25% of patients during the first 3 cycles (8.1% hand–foot syndrome, 7.7% diarrhea). The response rate was 13.6%, with a 69.7% disease control rate. Median progression-free survival (pfs) was 5.6 months. Post progression, 56 patients received further capecitabine monotherapy (median of 4 additional cycles). Median overall survival duration for the patients was 14.3 months. Median survival was significantly higher for those who, at baseline, had an ecog performance status of 0 (compared with 1 or more) and normal ldh (compared with elevated ldh).Conclusions Toxicity is less with dose-reduced capecitabine than with historical full-dose capecitabine, with only a small trade-off in efficacy, seen as a lower objective response rate. The improved tolerability could lead to an increased number of cycles of therapy, and pfs appears to be consistently higher at the lower dose. Those observations should, in the absence of a head-to-head clinical trial, be viewed as compelling evidence that 1000 mg/m2, or even 750 mg/m2, twice daily is an appropriate dose in elderly or frail patients with acrc.

PurposeGemcitabine plus cisplatin is active in malignant mesothelioma (MM), although single-arm phase II trials have reported variable outcomes. Vascular endothelial growth factor (VEGF) inhibitors have activity against MM in preclinical models. We added the anti-VEGF antibody bevacizumab to gemcitabine/cisplatin in a multicenter, double-blind, placebo-controlled randomized phase II trial in patients with previously untreated, unresectable MM.Patients and MethodsEligible patients had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 and no thrombosis, bleeding, or major blood vessel invasion. The primary end point was progression-free survival (PFS). Patients were stratified by ECOG performance status (0 v 1) and histologic subtype (epithelial v other). Patients received gemcitabine 1,250 mg/m2on days 1 and 8 every 21 days, cisplatin 75 mg/m2every 21 days, and bevacizumab 15 mg/kg or placebo every 21 days for six cycles, and then bevacizumab or placebo every 21 days until progression.ResultsOne hundred fifteen patients were enrolled at 11 sites; 108 patients were evaluable. Median PFS time was 6.9 months for the bevacizumab arm and 6.0 months for the placebo arm (P = .88). Median overall survival (OS) times were 15.6 and 14.7 months in the bevacizumab and placebo arms, respectively (P = .91). Partial response rates were similar (24.5% for bevacizumab v 21.8% for placebo; P = .74). A higher pretreatment plasma VEGF concentration (n = 56) was associated with shorter PFS (P = .02) and OS (P = .0066), independent of treatment arm. There were no statistically significant differences in toxicity of grade 3 or greater.ConclusionThe addition of bevacizumab to gemcitabine/cisplatin in this trial did not significantly improve PFS or OS in patients with advanced MM.

PurposeSunitinib is an oral, multitargeted receptor tyrosine kinase inhibitor of the vascular endothelial growth factor receptor and multiple other growth factor receptors. We assessed the safety and efficacy of sunitinib in patients with metastatic colorectal cancer after failure of standard therapy.Patients and MethodsEighty-four patients were enrolled onto this two-stage phase II trial and were stratified by whether they had received prior bevacizumab (n = 43) or not (n = 41). Treatment comprised sunitinib 50 mg orally daily for 4 weeks, followed by 2 weeks off treatment, in repeated 6-week cycles.ResultsBy Response Evaluation Criteria in Solid Tumors criteria, one patient, who was in the prior bevacizumab cohort, achieved a partial response, and 13 patients (two in the prior bevacizumab cohort and 11 in the no prior bevacizumab cohort) achieved stable disease lasting ≥ 22 weeks. Median time to progression in the prior bevacizumab and bevacizumab-naïve cohorts was 2.2 months (95% CI, 1.9 to 2.3 months) and 2.5 months (95% CI, 2.3 to 3.1 months), respectively, whereas median overall survival time was 7.1 months (95% CI, 4.9 to 10.6 months) and 10.2 months (95% CI, 8.2 to 15.3 months), respectively. The most common adverse events were fatigue, diarrhea, nausea, vomiting, and anorexia. Twenty-six patients (32%) required dose reduction to 37.5 mg/d, and one patient required dose reduction to 25 mg/d.ConclusionSunitinib did not demonstrate a meaningful single-agent objective response rate in colorectal cancer refractory to standard chemotherapy. However, the mechanisms of action and acceptable safety profile of sunitinib warrant further study in combination with standard regimens for metastatic colorectal cancer.

7081 Background: Targeting both vascular endothelial growth factor (VEGF) and platelet derived growth factor (PDGF) may be an appropriate therapeutic strategy in MM. MM express VEGF, PDGF, and their receptors, suggesting autocrine growth-stimulating loops. VEGF inhibitors and PDGF inhibitors have in vitro activity in MM. In MM patients (pts), high VEGF levels correlate with poor outcome. Vatalanib inhibits VEGF and PDGF receptor tyrosine kinases. Methods: We conducted a phase II trial of V in pts with unresectable, histologically-confirmed MM, measurable disease, no prior therapy, ECOG performance status (PS) 0–1. Primary endpoint: 3-month (mo) progression-free survival (PFS). V 1250 mg, was given orally daily. CT scans were obtained Q6 weeks. Baseline serum VEGF, PDGF were determined. Results: 47 eligible pts (46 evaluable) enrolled at 19 sites from 7/03–11/04. Pt characteristics: male 92%, median age 75 (range 51–92; 64% were >70). Histology: epithelial 80%, sarcomatoid 11%, biphasic 9%. Site of origin: pleura 87%, peritoneum 6%, other 6%. PS 0/1: 21%/ 79%. 261 cycles were administered, median 3, range 1–32; 2 pts continue treatment. Grade 3/4 toxicities: neutropenia 2%, lymphopenia 2%, nausea/vomiting 15%/9%, increased ALT/AST 9%/6%, hypertension 2%, gastrointestinal bleed 2%. Partial response: 11% (5 pts), stable disease 66%. 3-mo PFS: 55% (95% CI: 40%, 68%), median PFS: 4.1 mo; median survival 10.0 mo. Median baseline serum levels in 40 pts: VEGF 425 pg/mL, PDGF 22754 pg/mL. There was no correlation between baseline VEGF or PDGF levels and response, PFS, or survival. Conclusions: The study did not achieve the protocol-specified 3-mo PFS of 75%. However, the objective response rate of 11% and median survival of 10 months are similar to other active single-agents for MM, which suggests that V may warrant further study in this disease.
