7595 Background: Most SCLC patients initially respond to chemotherapy but then relapse and die so new therapies are urgently required. Pre-clinical data shows statins induce growth arrest and apoptosis in SCLC and several other tumour cell types and are additive with chemotherapy. This may in part be due to impaired Ras superfamily function as statins deplete mevalonate, reducing geranylgeranylation and farnesylation of these proteins. We therefore undertook this large pragmatic phase III trial in order to determine if overall survival (OS) was affected by the addition of pravastatin in SCLC. Methods: Patients with limited (LD) or extensive (ED) stage SCLC were randomised to pravastatin 40mg OD or placebo for up to 2 years and given standard chemotherapy according to local practice recommended as either cisplatin 60mg/m2 iv or carboplatin AUC 5 or 6 and etoposide 120 mg/m2iv d1 to 3 or 100 mg BD po d2 & 3; max 6 cycles plus radiotherapy as usually given. Patients were excluded if they had used statins within 12 months prior to randomisation. Stratification was: LD vs ED and ECOG 0,1 vs 2,3. Endpoints were: primary - OS; secondary - progression free survival (PFS), local PFS (local control), response rates (RR) and toxicity. Results: Between 2007 and 2012, 846 patients were randomised, 422 (49.9.%) received pravastatin and 424 (50.1%) placebo in 93 participating sites in the UK. The median age was 64 years (range 54-69); ECOG performance status: 0: 23%; 1: 54%; 2: 17% and 3: 6%; weight 72.6 kg; LD, 357 (42.2%); ED, 479 (56.6%); 211 (24.9%) had ipsilateral effusion and 201 (23.8%) had ipsilateral SCF lymph nodes; Relative Dose intensity of cisplatin/carboplatin and etoposide was 91.6% (range 80.8 to 99.7), and 94.7% (range 85.7 to 100); 83.4% vs 86.3% completed > 4 cycles of chemotherapy on the pravastatin and placebo arms respectively. Most patients completed 6 cycles of chemotherapy: 263 (62.3%) vs 265 (62.5%) in the pravastatin vs. placebo groups. Updated results showing OS, PFS, local PFS and toxicity will be presented. Conclusions: This trial will report on whether pravastatin 40 mg OD added to standard therapy alters the outcome for SCLC patients. Clinical trial information: ISRCTN56306957.

LBA10008 Background: Oral multikinase inhibitor regorafenib (REG) demonstrated substantial activity in a phase II trial in pts with GIST after failure of both IM and SU (J Clin Oncol. 2011; 29:606s; abstr 10007). This phase III, randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of REG for this unmet clinical need. Methods: Eligible pts had metastatic and/or unresectable GIST, objective failure of both prior IM and SU (progressive disease [PD] on, or intolerance to, IM and PD on SU), ≥1 measurable lesion, ECOG performance status 0 or 1. Pts were randomized 2:1 to receive best supportive care plus either REG 160 mg po once daily (3 wks on/1 wk off) or placebo (PL). The primary endpoint was progression-free survival (PFS) (modified RECIST 1.1, independent central review). Secondary endpoints included overall survival (OS), disease control rate (DCR, defined as rate of partial response [PR] plus stable disease [SD] lasting for ≥12 wks), response rate and duration, safety and correlative genotype analyses. At time of PD, pts were eligible for unblinding and crossover to open-label REG. Results: Between Jan and Aug of 2011, 234 pts were screened; 199 were randomized (REG: 133, PL: 66). Pts were stratified at randomization according to number of prior systemic therapies and geographical region. Baseline characteristics were balanced between the two arms. The primary endpoint was met: median PFS was 4.8 months for REG vs. 0.9 months for PL. Hazard ratio for PFS was 0.27 (95% CI, 0.18-0.39), p<0.0001. PFS rates at 3 and 6 months were 60% and 38% for REG vs. 11% and 0% for PL. DCR was 53% (REG) vs. 9% (PL).The HR for OS was 0.77 (p=0.20) with 85% PL pts having crossed over to REG. The most common > grade 3 treatment-emergent AEs in the REG arm during double-blind study were hypertension (28%), hand-foot skin reaction (21%), and diarrhea (8%). Conclusions: This randomized trial demonstrated that REG significantly improved PFS and DCR in pts with advanced GIST after failure of at least prior IM and SU. REG was well tolerated, with AEs as expected for this class and manageable with dose modifications.

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.

Advanced Gist

LBA10502 Background: To palliate and prolong disease control after failure of all available treatment in advanced GIST, resumption of IM dosing has been commonly practiced based on evidence of rapid GIST progression after discontinuation of all TKIs. We evaluated the efficacy of IM rechallenge in pts with advanced GIST following failure of all TKIs. Methods: Eligible pts had metastatic and/or unresectable GIST with prior benefit from first-line IM (defined as disease control for > 6 months), progressive disease (PD) on first-line IM, PD on or intolerance to SU, and ECOG performance status 0-3. Pts were randomized 1:1 to receive best supportive care with either IM 400 mg po once daily or PL. At the time of PD, pts were unblinded and allowed to cross-over to open-label IM. The primary endpoint was progression-free survival (PFS) determined by blinded external radiology review according to RECIST v1.0. Secondary endpoints included overall survival (OS), time to progression, disease control rate (DCR) at 12 weeks, and safety. Results: Between July 2010 and January 2013, 81 pts were randomized (IM: 41, PL: 40) at a single Korean center. All baseline characteristics were balanced between the arms and 40% of pts received ≥ 3 prior TKIs. The planned final analysis in March 2013 demonstrated that the primary endpoint was met, with significantly greater PFS for pts randomized to IM vs. PL : 1.8 vs. 0.9 months, respectively (p=0.002), hazard ratio (HR) 0.45 (95% CI, 0.27-0.76). DCR at 12 weeks was 32% for IM vs. 5% for PL (p=0.003). With 92.5 % of PL pts rapidly crossing over to IM, median OS was 8.2 months for IM vs. 7.5 months for PL (HR of 0.99, p=0.982). The most common treatment-emergent AEs (> grade 3) during double-blind period in the IM arm included anemia (29%), fatigue (10%), and hyperbilirubinemia (7%). Conclusions: Rechallenge of IM significantly improves PFS and DCR in pts with advanced GIST after failure of at least IM and SU, likely by continuous kinase inhibition of the bulk of disease clones which retain IM sensitivity. However, TKI-resistant clones continue to progress leading to relatively brief duration of benefit. Clinical trial information: NCT01151852.

IntroductionStereotactic body radiotherapy (SBRT) is a non-invasive alternative to surgery for the treatment of non-metastatic prostate cancer (PC). The objectives of the Novel Integration ofNew prostate radiation schedules with adJuvant Androgen deprivation (NINJA) clinical trial are to compare two emerging SBRT regimens for efficacy with technical substudies focussing on MRI only planning and the use of knowledge-based planning (KBP) to assess radiotherapy plan quality.Methods and analysisEligible patients must have biopsy-proven unfavourable intermediate or favourable high-risk PC, have an Eastern Collaborative Oncology Group (ECOG) performance status 0-1 and provide written informed consent. All patients will receive 6 months in total of androgen deprivation therapy. Patients will be randomised to one of two SBRT regimens. The first will be 40 Gy in five fractions given on alternating days (SBRT monotherapy). The second will be 20 Gy in two fractions given 1 week apart followed 2 weeks later by 36 Gy in 12 fractions given five times per week (virtual high-dose rate boost (HDRB)). The primary efficacy outcome will be biochemical clinical control at 5 years. Secondary endpoints for the initial portion of NINJA look at the transition of centres towards MRI only planning and the impact of KBP on real-time (RT) plan assessment. The first 150 men will demonstrate accrual feasibility as well as addressing the KBP and MRI planning aims, prior to proceeding with total accrual to 472 patients as a phase III randomised controlled trial.Ethics and disseminationNINJA is a multicentre cooperative clinical trial comparing two SBRT regimens for men with PC. It builds on promising results from several single-armed studies, and explores radiation dose escalation in the Virtual HDRB arm. The initial component includes novel technical elements, and will form an important platform set for a definitive phase III study.Trial registration numberANZCTN 12615000223538.

PurposeThis phase III study compared the safety and efficacy of the following three different irinotecan-containing regimens in the first-line treatment of metastatic colorectal cancer: irinotecan plus infusional fluorouracil (FU)/leucovorin (LV) (FOLFIRI), irinotecan plus bolus FU/LV (mIFL), and irinotecan plus oral capecitabine (CapeIRI).Patients and MethodsA total of 430 previously untreated metastatic colorectal cancer patients were randomly assigned to receive FOLFIRI (n = 144), mIFL (n = 141), or CapeIRI (n = 145). Patients were concurrently randomly assigned to a double-blind treatment with celecoxib or placebo. After a protocol amendment, an additional 117 patients were randomly assigned to either FOLFIRI plus bevacizumab (FOLFIRI+Bev; n = 57) or mILF plus bevacizumab (mIFL+Bev; n = 60), whereas the CapeIRI arm was discontinued. The primary study end point was progression-free survival (PFS), with secondary end points of overall survival (OS), response rate, and toxicity.ResultsMedian PFS was 7.6 months for FOLFIRI, 5.9 months for mIFL (P = .004 for the comparison with FOLFIRI), and 5.8 months for CapeIRI (P = .015). Median OS was 23.1 months for FOLFIRI, 17.6 months for mIFL (P = .09), and 18.9 months for CapeIRI (P = .27). CapeIRI was associated with higher rates of severe vomiting, diarrhea, and dehydration. After the amendment to add bevacizumab, the median survival time has not yet been reached for FOLFIRI+Bev and was 19.2 months for mIFL+Bev (P = .007). FOLFIRI+Bev was associated with a higher rate of ≥ grade 3 hypertension than mIFL+Bev.ConclusionFOLFIRI and FOLFIRI+Bev offered superior activity to their comparators and were comparably safe. An infusional schedule of FU should be the preferred irinotecan-based regimen in first-line metastatic colorectal cancer.

4601 Background: A phase I/II study with GV1001, a telomerase peptide vaccine, showed a median overall survival (OS) of 8.6 months in non-resectable PC (Bernhardt SL et al, Br J Cancer. 2006;95:1474–1482). This phase III trial was conducted to determine the impact on overall survival of G monotherapy vs. GV1001 in sequential combination with G in unresectable and metastatic PC. Methods: Eligible patients (pts) had chemotherapy-naive, advanced PC and ECOG performance status 0–1. Pts were randomized 1:1 to receive arm A: G (1,000 mg/m2 30 min i.v.) weekly for 7 weeks (w), 1w off and then 3w during 4-weekly cycles, or arm B: GV1001 0.56 mg s.c. plus GM-CSF as immune adjuvant on days 1, 3, 5, 8, 15, 22, 36, then every 4 weeks. Patients who progressed clinically or radiologically during GV1001 continued on GV1001 and concomitant gemcitabine. CT scans were performed every 8 weeks. The primary end-point was OS. A sample size of 520 patients allowed the detection of a hazard ratio (HR) of 0.73 (B/A), with 2α = 0.05 and 90% power. Results: Between June 2006 and May 2008, 365 pts were enrolled (A / B; 182 / 183). The study was stopped prematurely due to a preliminary analysis with 178 events showing no survival benefit of GV1001. Pts were well balanced for baseline characteristics: male 59.3% / 62.8%; median age 61y / 61y; ECOG PS 0 34.3% / 36.7%; locally advanced 22.4% / 20.7%. As of August 2008, 238 pts (A / B : 114 / 124) had died. Median OS was 7.3 / 5.9 months (HR 0.8; 95% CI 0.6–1.0). Median progression-free survival (PFS) was 3.7 / 1.9 months (HR 0.5; 95%CI 0.4–0.7). Grade 3–4 AEs: gastrointestinal 6% / 8%, infection 5% / 5%, vascular disorders 2% / 3%, neutropenia 6% / 3%. Conclusions: GV1001 did not show efficacy in sequential combination with G in advanced PC. The advantage of G monotherapy over the sequential combination may be due to the delayed treatment with G in arm B. [Table: see text]

7565 Background: Standard first-line chemotherapy for elderly NSCLC pts has been considered as a monotherapy with vinorelbine or gemcitabine globally. However, we have demonstrated the high efficacy of CP for elderly pts in our previous trial (Ann Oncol 2010). Meanwhile, D has been considered as an alternative option for this population in Japan according to the result of WJTOG9904 (JCO 2006). Thus we compared the two regimens to select the proper candidate for future phase III trial. Methods: Eligible pts were aged 70 years or older with newly diagnosed stage IIIB/IV NSCLC; ECOG performance status 0-1; adequate organ function; written informed consent. Pts were randomized to receive carboplatin (AUC 6) on day 1 and paclitaxel (70mg/m2 on day 1, 8, and 15) every 4 weeks or D (60mg/m2 on day 1) every 3 weeks. The primary endpoint was overall response rate (ORR), and secondary endpoints were progression-free survival (PFS), overall survival, and toxicity profile. Assuming that ORR of 40% would be potential usefulness while ORR of 20% would be the lower limit of interest, 40 pts in each arm were required if expect 10% loss to follow up. Results: Between July 2006 and September 2010, 84 pts were enrolled and 41 pts in CP arm and 42 pts in D arm were eligible (median age, 76 years; 75% male; 72% stage IV). Median treatment cycle was 4 in each arm (CP, range 1-6; D, range 1-8). ORRs were 51% (95%CI: 36-66%) and 26% (95%CI: 12-39%) in the CP and D arm, respectively. With a median follow-up of 18.4 months, median PFS were 6.5 and 3.9 months in the CP and D arm, respectively (Logrank, P=0.0027). Grade 3 or severer toxicities were as follows: neutropenia (CP, 56% and D, 79%), anemia (CP, 15% and D, 7%), thrombocytopenia (CP, 10% and D, 0%), infection (CP, 20% and D, 25%). One treatment-related death due to neutropenia, pneumonia, and lethal arrhythmia occurred in D arm but none in CP arm. Conclusions: The platinum doublet CP achieved higher activity with an acceptable toxicity profile for elderly pts with advanced NSCLC compared to monotherapy with D. The superiority of CP to the monotherapy in this trial is consistent with results of recent IFCT-0501 trial (Lancet 2011).

587 Background: Patients with liver metastases (LM) from colorectal cancer (CRC) have a severe prognosis with the 5-year survival of 25% after radical resection; for not operable metastases the survival is poor. Embolization using polyvinil alcohol microspheres loaded with IRI 200 mgr (D) is a feasible procedure. FOLFIRI (CT) is active for the treatment of CRC. We planned this phase III study to assess survival as primary endpoint to increase median survival (MS) by 40% at 2-y (HR=0.72). QoL, responses, progression-free survival (PFS) and safety are secondary endpoints. Methods: Between December 2006 and December 2008, 74 pts were randomized, 37 patients to D and 37 to CT. Two D patients had early progression and two CT patients refused. 70 cycles of D were administered in 35 pts, with a dose intensity (DI) of 99%, and 292 CT cycles were delivered to 35 pts with a DI of 90%. Results: At a median follow up of 30 months ( 18-42) we reported (D vs CT): MS 48% vs 28%, Response Rate 70% vs 20%, Acute Toxicity 70% vs 20%, Late Toxicity 20% vs 80%, QoL improvement 65% vs 25%, Costs for each pt: 7,000 vs 24,000 euro. Conclusions: D increased the 30-Months MS difference of 20% compared to CT. D improved responses, Performance Status and reduced costs. D reported higher immediate toxicity, mainly fever and abdominal pain, than CT. Late toxicity, mainly haematological, diarrhoea, asthenia and alopecia, was more common in CT. We conclude that D compared to CT increases survival and palliative results in patients with LM from CRC.

3575 Background: The literature reports that adding biologics to chemotherapy (ctx) may increase the incidence of clinically significant neutropenia. his trial was conducted to evaluate the efficacy of PEG in reducing the incidence of febrile neutropenia (FN) in pts with locally-advanced (LA) or metastatic (m)CRC receiving first-line treatment with either FOLFOX/B or FOLFIRI/B. Methods: Key eligibility: ≥ 18 years old; measurable, nonresectable CRC per RECIST 1.1. Pts were randomly assigned 1:1 to either placebo or 6 mg PEG ~24 h after ctx/B. The study treatment period included four Q2W cycles, but pts could continue their assigned regimen until progression. Pts were stratified by region (North America vs rest of world), stage (LA vs mCRC), and ctx (FOLFOX vs FOLFIRI). Estimated sample size (N = 800) was based on the expected incidence of grade 3/4 FN (primary endpoint) across the first 4 cycles of ctx/B, powered for PEG superiority over placebo. Other endpoints included overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). Results: 845 pts were randomized (Nov 2009 to Jan 2012) and received study treatment; 783 pts completed 4 cycles of ctx/B. Median age was 61 years; 512 (61%) pts were male; 819 (97%) had mCRC; 414 (49%) received FOLFOX, and 431 (51%) received FOLFIRI. Grade 3/4 FN (first 4 cycles) for placebo vs PEG was 5.7% vs 2.4%; OR 0.41; p = 0.014. A similar incidence of other ≥ grade 3 adverse events was seen in both arms (28% placebo; 27% PEG). See table for additional results. Conclusions: PEG significantly reduced the incidence of grade 3/4 FN in this pt population receiving standard ctx/B for CRC. Follow-up is ongoing. Clinical trial information: NCT00911170. [Table: see text]

TPS5613 Background: Folate receptor (FR) is expressed on the majority of epithelial ovarian cancers and FR expression appears to be a negative prognostic factor in this setting. Vintafolide (EC145) is a folate-conjugate designed to selectively deliver desacetylvinblastine monohydrazide (DAVLBH) to FR-expressing cells. 99mTc-Etarfolatide (EC20) is a technetium-labeled folate that identifies FR-expressing tumors. In a phase 2 study comparing vintafolide + PLD with PLD alone, the combination demonstrated a statistically and clinically significant delay in PFS (5.0 months) compared with PLD alone (2.7 months) in women with platinum-resistant ovarian cancer (Naumann et al, ASCO 2011). Data also indicated that 99mTc-etarfolatide may have utility for selecting patients most likely to benefit from vintafolide therapy. Methods: This is an international, randomized, double-blind, placebo-controlled phase 3 study of PLD ± vintafolide therapy compared in patients with primary or secondary platinum-resistant ovarian cancer (NCT01170650). Key eligibility criteria include: ≥18 years, pathology-confirmed epithelial ovarian, fallopian tube or primary peritoneal carcinoma, prior platinum-based chemotherapy, a RECIST v1.1 measureable lesion, and ECOG performance status 0 or 1. At baseline, patients undergo 99mTc-Etarfolatide imaging to identify FR-positive lesions and are subsequently randomized to the vintafolide ± PLD. PLD (50 mg/m2) adjusted for Ideal Body weight is administered on day 1 of a 4-week cycle and treatment continues until the maximum allowable cumulative dose (550 mg/m2) is reached or until disease progression or intolerable toxicity. Vintafolide (2.5 mg) or placebo is administered on days 1, 3, 5, 15, 17, and 19 of a 4-week cycle and treatment can continue for up to 20 cycles or until unacceptable toxicity or disease progression. The primary objective is to assess PFS based on investigator assessment (RECIST v1.1) in FR positive patients. Secondary objectives include OS, safety/tolerability, overall response rate, and disease control rate. Enrollment to the study is currently ongoing. Clinical trial information: NCT01170650.
