10563 Background: P inhibits activation of the Akt pathway which results in apoptosis and block cancer cell proliferation. Since AKT is a molecule downstream of Kit, its inhibition may overcome Kit-dependent imatinib resistance. We performed a phase II trial to assess antitumor activity of perifosine in patients with advanced GIST who were refractory to imatinib mesylate. Methods: Pts with Kit(+) advanced GIST who have PD on IM were eligible. Pts continued their current dose of IM and were randomized to one of two dosing schedules of P (Arm A: 100 mg p.o. qd x 28 + IM or Arm B: 900 mg [300 mg p.o tid] qweekly + qd IM). A Bayesian approach was utilized to assess a target response rate or 20% with an unacceptable toxicity rate of 15% or less. Response was measured at q8 wk intervals by RECIST and Choi criteria. The primary endpoint was to determine the efficacy of P with IM in pts with advanced GIST with PD while receiving IM. Results: From 8/2005 to 7/2008, 41 pts were accrued. After 1 pt exclusion and 2 cross-overs, 22 pts were in Arm A and 18 pts in Arm B. Median age was 58 (range, 32–82), 51% were male, and median ECOG PS was 1. The most common primary site of disease and metastasis was the stomach (29%) and liver (66%), respectively. KIT genotype was available for 22 pts(54%); 5(12%) WT, 13(32%) exon 11 mutations, and 4(10%) exon 9 mutations. The median number of cycles was 2 (range, 1–24). By Choi and RECIST, 30 pts(73%) and 36 pts(87%) were available for response, respectively. No CR was identified but the PR rate was 4/36 (11%) by Choi (4 PR, 9 SD) and 0/36 (0%) by RECIST (16 SD). 4/5 (80%) of pts with WT KIT appeared to benefit (Choi: 1 PR, 3 SD; RECIST: 4 SD). Median PFS and OS for 40 pts were 2.2 months and 18.3 months. No difference in PFS was noted for the 2 schedules. Toxicity was assessed in 39 pts; 46 grade 3 events and 4 grade 4 events (ALT elevation, blurred vision, fatigue, and mood alteration) were noted. The most common grade 3 event was fatigue (20%). Three pts (7%) were removed from the study for toxicity (Arm A:1 pt, Arm B:2 pts). Conclusions: The addition of P to IM has minimal activity in IM-refractory GIST although its activity in GIST with WT KIT may be further investigated.

7084 Background: the combination of CPT-11 and CDDP (IP) is an active regimen for SCLC. (Noda et al NEJM ’02, Hanna et al ASCO 2005). We performed a multicenter phase II study to assess the efficacy and toxicity of IP regimen with concurrent TRT in previously untreated LS-SCLC pts. Methods: Eligible pts were required to have histologically confirmed SCLC, measurable disease, no prior therapy, ECOG PS of 0–2, adequate organ functions, and to give informed consent. Treatment consisted of: CDDP 60 mg/m2 D1, I 60mg/m2 IV D1, 8 Q 21D for 4 cycles, and concurrent TRT 2.0 Gy daily to a total of 60.0 Gy, beginning with the 2nd cycle. I was adjusted to 50 mg/m2 at 2nd and 3rd cycles (during TRT). Pts were restaged after 4 cycles. Pts without progression or undue toxicity received 2 additional cycles. PCI (2.0 Gy X 10) was offered to CR pts. The primary endpoints were response rate and OS. Results: Twenty-six pts were included and 25 pts were evaluable for response (median age 62; M/F, 22/4; PS 0/1/2, 9/17; T2–4N0,T2–4N+ 6/20pts). Among 126 cycles administered, the relative dose-intensities of I and CDDP were 80% and 92% respectively. Median number of cycles/pt was 5 (1–6), and 22 pts completed the IP + TRT program. Fifteen pts achieved a CR and 6 pts a PR, for an overall RR of 84%. Median TTP was 12 months. At a median follow-up of 14 months, 19 pts are alive, and estimated median survival is 17 months. Grade 3–4 (NCI-CTC 3.0) toxicity (per cycle) during concurrent therapy included: neutropenia (25%), anemia (3%), thrombocytopenia (3%), diarrhea (10%), vomiting (5%), esophagitis (10%). There were no treatment-related deaths. Two pts required hospitalization during the concurrent therapy due to g3 diarrhea (1 pt) and febrile neutropenia (1 pt). Conclusions: The concurrent regimen of IP + TRT is highly effective in pts with LS-SCLC. The associated toxicity profile is predictable and adequate. Further study is warranted.

4519 Background: Gemcitabine (G) is standard for metastatic pancreatic cancer (PC), with median survivals of 6 months (m). Second cytotoxic or biologic agents do not substantially advance survival. EGFR is expressed on PC and a phase II trial of G plus cetuximab (C) resulted in favorable 1 year survival. A phase II trial of irinotecan/docetaxel (I/D) chemotherapy reported a median survival for metastatic patients (pts) of 9 m. We conducted this randomized phase II trial to confirm the activity of this non-G regimen, and determine whether combining it with C was feasible and active. The primary endpoint was response. Methods: Pts required histologic confirmation of adenocarcinoma of the pancreas, evidence of distant metastases, ECOG PS 0–1, normal bilirubin, written informed consent, and were randomly assigned to Arm A (N=47) or B (N=45). Imaging with CT or MR within 4 weeks (wk) was used for tumor measurement. Dexamethasone was given 12 hours (h), 1 h before and 12 h after chemotherapy. Pts on Arm A received D 35 mg/m2 over 1 h and I 35 mg/m2 over 30 minutes weekly x 4 in a 6 wk cycle. Pts on Arm B received the same therapy, but C (loading dose 400 mg/m2 wk 1, 250 mg/m2 weekly thereafter) was given before D. Pts not receiving therapeutic anticoagulation received enoxaparin 40 mg per day. Pts were restaged (RECIST) after 2 cycles. Results: Median age Arm A: 59.9, Arm B: 60.2 years. Arm A 55% male, 32% PS 0, 97% EGFR immuno+. Arm B 84% male, 42% PS 0, 97% EGFR +. Median number of cycles for each arm 2 (1 -10). >4 cycles were delivered to 10.5% of pts Arm A, 20.9% Arm B. Grade ¾ neutropenia 26% Arm A, 33% Arm B. Grade 3 nausea 28% Arm A, 18% Arm B; Grade ¾ diarrhea 33% Arm A, 44.4% Arm B. 1 treatment-related death per arm. Median overall survival (OS), with 70.2% of pts known to have died, 6.5m [(95% CI (4.8, 8.6)] in Arm A. With 86.7% of pts known to have died in Arm B, OS 7.4 m [95% CI (4.4, 10.7)]. Response/progression data will be available at time of presentation. Conclusions: Weekly I/D ± C is associated with high rates of grade ¾ neutropenia/diarrhea. Median survival is 6.5m for I/D and 7.4m for I/D/C. Non-G containing therapy is active in metastatic PC. [Table: see text]

4102 Purpose: To compare oxaliplatin (L-OHP) plus raltitrexed (RTX) with L-OHP plus fluorouracil and leucovorin (LV/5FU) for patients (pts) with recurrent and metastatic colorectal cancer(CRC). Methods: Eligible pts had to have histologically proven recurrent or metastatic CRC,not having previously received oxaliplatin as palliative chemotherapy,ECOG PS = 2,age:18∼70,and adequate hematological,renal and hepatic function.After written informed consent,pts were randomized to L-OHP:130 mg/m2 d1 + RTX: 3 mg/m2 d1 (Arm A) or + LV: 200 mg/m2 + 5FU:375 mg/m2 d1–5 (Arm B). Results: Between Jan 2005 and July 2006, 216 pts were enrolled at 15 centers in China.112 pts (mean age: 55.0 (19∼70), M/F: 57/46, PS 0/1/2: 46/53/13) were randomly assigned to A and 102 (mean age: 54.2(22∼70), M/F: 54/46, PS 0/1/2: 44/59/9) to B. 203 pts were eligible for response evaluation (A:103, B:100).The median number of cycles was 4 (1∼6) in A and 3 (1∼6) in B (P=0.1431).The RR was 29.1% (CR:2, PR:28, SD:50 , PD:23) in A and 17.0% (CR:2, PR:15, SD:46 , PD:37) in B (P=0.0437).The disease-control rate was 77.7% in A and 63.0% in B (P=0.0237). After a median follow-up of 10 months (4–16.5),92 pts had had progression of disease (40 in A and 52 in B); 73 deaths had occurred (35 in A and 38 in B), median time to progression was not reached. Following-up is ongoing.The median QoL scores for the two arms were comparable. 214 were included in the safety analyses (A:112, B:102). There was a higher incidence of neutropenia (48.2% verse 29.4%, P=0.005) and transaminase increase (49.1% verse 35.3%, P=0.041) among A. Grade 3 or 4 neutropenia was much common in pts in A than those in B (20.5% verse 4.9% , P=0.001), but was complicated by fever in only 3.6% of cases (4 pts) in A and in 2.9% of cases (3 pts) in B. No pts were dead or infectious due to neutropenia. There were similar rates of grade 3 or 4 transaminase elevation in the two groups. Vomitting and anorexia were much commoner with B. Conclusions: The L-OHP+RTX seems beneficial in recurrent and metastatic CRC, demonstrating better response rate and higher disease control rate with acceptable tolerability, maintenance of QoL and convenient administration schedule.

The Cost

e15624 Background: There is no established 2nd line therapy for patients (pts) with advanced gastroesophageal (GE) cancer. In 2004, the Danish government initiated a national health programme for pts with advanced cancer. Non- proven therapy may be offered after approval by an expert panel appointed by the National Board of Health that subsequently finances the cost of treatment. This programme has had a major impact on the management of cancer pts in Denmark and has accelerated the introduction and implementation of new therapies. Inspired by the excellent results in colorectal cancer a combination of cetuximab and irinotecan (CetIri) was chosen for platinum-resistant GE cancer. While awaiting approval of a phase II protocol CetIri was offered at a single institution. We report our preliminary experience with biweekly CetIri as 2nd line therapy in pts with GE cancer. Methods: All pts had histologically confirmed GE cancer (adeno- or squamous cell carcinoma) and all pts had previously received first line platinum based therapy. Pts received CetIri (cetuximab 500 mg/m2and irinotecan 180 mg/m2day 1) every 2nd week until progression or unacceptable toxicity. Response rate was evaluated by the investigator according to RECIST every 8th week. Toxicity was prospectively evaluated according to NCIC-CTC 3.0. Results: From December 2007 to August 2008, 31 consecutive pts was treated with CetIri. Median age was 62 years (33–76). Median performance status was 1 (0–2). Localisation of primary was: Esophagus 10%, GE junction 64%, gastric 26%. Twenty-seven pts (87%) had adenocarcimona. Median number of cycles were 6 (1–21). Most important grade 2–4 toxicities were non-haematological toxicity as diarrhea (25%), nausea (21%) and vomiting (11%). Three pts (11%) had grade 3 leukopenia, 1 had febrile neutropenia. Two pts had PR. Median PFS was 3.2 months. Fourteen pts (45%) received at least 6 courses (3 month of therapy). After a median follow-up of 6 month 5 pts continue CetIri without sign of PD. Conclusions: Biweekly CetIri is a convenient and well-tolerated 2nd line regimen in pts with GE cancer. Predictive factors are needed to select which pts will benefit from therapy. A confirmatory phase II study is ongoing. [Table: see text]

7109 Background: We previously reported results of treating MF patients with 3 cycles of 300, 400, or 500 mg of SAR302503 (NCT01420770; Blood 2012;120:21 Abs 2837). This is a report of efficacy and safety after 6 cycles. Methods: Patients ≥18 years of age with intermediate-2 or high-risk MF and splenomegaly were eligible. SAR302503 is administered orally, once a day in consecutive 4-week cycles until disease progression or unacceptable toxicity. Spleen response (≥35% reduction in spleen volume vs baseline) was assessed by MRI/CT (blinded independent central review). Results: 31 patients were enrolled (n=10 in the 300 and 400 mg groups; n=11 to 500 mg). Risk status was balanced in all but the 300 mg group (70% high-risk). Most patients were JAK2V617F positive (90%) and blood transfusion independent (81%). Spleen response rates at the end of cycle (EOC) 6 (secondary end point) were 30% (3/10) in the 300 mg group, 60% (6/10) with 400 mg, and 55% (6/11) with 500 mg compared with EOC 3 rates of 30%, 50%, and 64%, respectively. One patient on 500 mg who had a spleen response at EOC 3 (39% reduction), but not at EOC 6 (25% reduction) had dose reductions to 200 mg due to anemia. Median number of cycles was 13 (range, 2–17) and 24 patients have been on treatment >12 months. SAR302503 reduced baseline constitutional symptoms at the EOC 3, with the greatest responses for night sweats in 14/15 patients (93%), itching 10/14 (71%), early satiety and abdominal pain, each in 10/18 (56%). Most common adverse events were anemia and diarrhea, with grade 3–4 rates of 58% and 13%, respectively. The rate of grade 3–4 thrombocytopenia was 16%. There was no grade 3–4 neutropenia. The diarrhea rate tended to decrease after the first 2 treatment cycles. There have been no reports of withdrawal syndrome after stopping SAR302503. Median JAK2V617F allele burden was 93% at baseline, 87% at the EOC 3, and 78% at EOC 6 in 19/26 patients who had available samples. The expression of 22 of 97 cytokines was significantly regulated (≥1.5 fold difference; p<0.05) after cycle 1. Conclusions: In this Phase II trial, continued treatment with SAR302503 was associated with clinically meaningful reductions in splenomegaly. Symptom data will be updated. Clinical trial information: NCT01420770.

3587 Background: There are few therapies for second-line KRASm CRC. Inhibiting downstream signal transduction may offer therapeutic options. Use of selumetinib (MEK 1/2 inhibitor; AstraZeneca) is supported by preclinical and clinical evidence. We designed a dose-finding/phase II study of IRI + SEL in KRASm CRC. Methods: Eligibility included: KRASm or BRAFm CRC with measurable disease progressing after 1st-line therapy with an oxalipatin + bevacizumab regimen; PS 0-1; acceptable organ function. Patients (Pts) were treated with IRI 180 mg/m2 iv q2w and SEL 50 or 75 mg po bid. Dose escalation was traditional 3+3 (50 mg bid SEL, then 75 mg bid). In Part B/phase II, primary endpoint was PI-determined response rate (RR) by RECIST. A Simon 2-stage design allowed expansion to 45 pts if ≥1 responses in 20 pts was seen; ≥4/45 responses would be encouraging, when compared to historical RR of 4% (and median PFS 2.5 mo) [EPIC, Sobrero 2008], with approximately 90% power to detect an ORR of 15% at the 10% alpha level (one-sided). Results: N =32 pts entered; 31 treated. Median age was 54 (27-75) yrs; 18 male and 24 Caucasian. The first 3 pts tolerated SEL 50 mg bid without DLT and the remaining 28 were treated at 75 bid. Median number of cycles on study was 3.5 and median PFS was 3.4 mo. Grade 3 AEs included (N): diarrhea 3, fatigue 2, neutropenia 2, and 1 each thrombocytopenia, enteritis, GI bleed, rash. There was one Grade 4 neutropenia. The best PI-reported response included 3 (10%) confirmed PR and 16 (52%) SD [including 1 unconfirmed PR]. 6 patients were on study for more than 6 (up to 22) months. The study was terminated early due to non-protocol considerations. Conclusions: In this small study, the RR of 10% and med PFS of 3.4 mo in pts with KRASm CRC treated with IRI + SEL in 2nd line are promising compared with prior studies in non-selected patients. MEK inhibition in KRASm CRC should be explored further. Supported in part by AstraZeneca.

Clinical Trial Information

2019^ Background: Patients (pts) with GBM with unmethylated MGMT have a worse prognosis than those with methylated MGMT. Novel approaches for this poor risk group are warranted. The Brain Tumor Trials Collaborative (BTTC) performed a phase II trial evaluating standard chemoradiation followed by bevacizumab and erlotinib in patients with MGMT unmethylated GBM. EGFR and VEGFR are upregulated during radiation suggesting that this combination could be more effective than post-radiation adjuvant temozolomide (TMZ). Methods: After informed consent, adult patients with supratentorial GBM, KPS ≥ 70 and > 1 cm2 tumor block for MGMT promoter analysis were screened. Only tumors with confirmed unmethylated MGMT promoter were enrolled. All patients received RT + TMZ and then approximately 4 weeks after RT they received bevacizumab 10 mg/kg every 2 weeks and erlotinib 150 mg/day, continuously. One cycle was 4 weeks; evaluation by MRI was every 2 cycles. Treatment continued until disease progression or intolerable adverse events. Results: 115 patients were screened; 48 were enrolled (2 unevaluable: 1 for an infratentoral GBM and 1 withdrew after 7 days of treatment) with 29 men, 17 women. Median age was 56 yrs (29-75); median KPS was 90 (70-90). The median number of cycles was 8 (2-38) with 4 patients remaining on trial at the time of analysis. Objective responses: 4 CR, 12 PR and 30 SD. Median PFS is 7.3 months (95% CI (6.4, 11)) and median OS 14.2 months (95% CI (10.7, not reached)). There were no unexpected toxicities; grade 3/4 rate < 5%. Conclusions: Adjuvant bevacizumab and erlotinib in GBM with unmethylated MGMT is well tolerated. Preliminary efficacy data is comparable with outcomes in similar unmethylated MGMT patient populations from the EORTC/NCIC and RTOG 0525 studies. Tissue correlation is being performed. Clinical trial information: NCT00720356.

5135 Background: In a PC-3 tumor cell model YM155 inhibited survivin mRNA transcription and survivin protein expression and showed potent (nM) anti-proliferation activity with strong signs of tumor regression. In a phase I study, two highly refractory HRPC patients exhibited a > 50% reduction of PSA from baseline. Methods: Patients with metastatic HRPC who received prior taxane chemotherapy were eligible. The primary endpoint is PSA response rate (decline by ≥ 50%). Other endpoints include objective tumor response by RECIST and evaluation of toxicity. A two stage Simon study design required one response in stage I (N=13) and 3 responses in stage II (N=14). If 4 responses are achieved then an additional 33 pts (N=60) will be enrolled to further characterize the efficacy and safety. Patients are considered evaluable if they complete 2 cycles. YM155 is given as a 168 hour continuous infusion every three weeks (1 cycle) at a dose of 4.8 mg/m2/day. Results: First two stages are enrolled with treatment ongoing. Data on 32 pts is provided. Median age is 67 y/o (range 53 - 81) with ECOG PS of 0 - 2. All but one patient received at least one prior taxane containing regimen. Two patients are PSA responders to date. One achieved response at cycle 2 (currently at cycle 3) and one at cycle 6 (currently at cycle 10). The median number of cycles is 3 (range 1 - 10). Two patients discontinued due to adverse events; in only one patient was the event (fever) considered related to study drug. Five/32 patients reported grade 3, 4, or 5 AE considered related to drug (coagulopathy secondary to coumadin therapy followed by intracranial hemorrhage, fatigue, URI, decreased Hgb, thrombocytopenia). Seven/32 patients remain on drug including the two responders. Conclusions: The preliminary data of YM155 in HRPC demonstrates activity and has an acceptable toxicity profile. No significant financial relationships to disclose.

Weekly Cisplatin

18150 Background: Every 3-week cisplatin doublets used to treat advanced NSCLC carry a significant risk of renal and other toxicities and can be difficult for patients with co-morbidities. To reduce these toxicities, we conducted a phase II study to evaluate the efficacy and toxicity of weekly cisplatin and docetaxel in advanced NSCLC. Methods: Eligibility included patients with advanced or recurrent NSCLC, ECOG PS of 0–1, and no prior chemotherapy for metastatic disease. This Cancer Institute of New Jersey network, single stage phase II clinical trial was designed to give 3 weekly doses of cisplatin at 25 mg/m2 and docetaxel at 35 mg/m2, followed by 1 week of rest, for a total of 6 cycles of therapy. Toxicity was monitored weekly, and disease evaluation was performed every 2 cycles. The primary endpoint was response rate (RR); secondary endpoints included time to progression (TTP), median and 1-year survival. Results: From 12/03 to 11/06, 36 patients were enrolled so far. The median age of patients is 63 (range 47–78), the majority is white (n=33), 29 have stage IV disease, and half (n=18) are women. Fourteen have an ECOG PS=0 and 22 with PS=1. Histologic subtypes are: adenocarcinoma (n=24), NSCLC NOS (n=7), squamous (n=5). Eleven patients received = 4 cycles of therapy; median number of cycles delivered is 2.5. Reasons for treatment discontinuation include completion of therapy (n=5), progression of disease (n=16), adverse events (n=8), and patient preference (n=4). Three patients continue on therapy at this time. No complete responses were yet observed; 8 patients (22%) achieved a partial response; 10 patients had stable disease, 10 patients progressed, and 8 came off study before first disease evaluation. Median TTP was 3.1 months (mo) (95% CI 2, 5.5), median survival is 8.3 mo (95% CI 5,16.2) and 1-year survival is 39% (95% CI 20, 57). Most toxicities were mild but also included neutropenia (grade 3, n=1; grade 4, n=1), neutropenic fever (n=1), renal toxicity (grade 3, n=2), nausea (grade 3, n=1), fatigue (grade 3, n=3), diarrhea (grade 3, n=4) and metabolic abnormalities (grade 3, n=3). Conclusion: Weekly cisplatin and docetaxel is well tolerated with a low incidence of toxicity and demonstrates activity similar to every 3-week treatment in patients with advanced NSCLC. No significant financial relationships to disclose.

e19023 Background: Bevacizumab (B), in addition to platinum-based chemotherapy, is indicated for 1st-line treatment of p with advanced NSCLC other than predominantly squamous cell histology. B has been shown to improve progression free survival (PFS) and overall survival (OS) when combined with cisplatin/gemcitabine and carboplatin/paclitaxel, respectively. However, there are limited data on the safety and efficacy of B in combination with other widely used chemotherapy doublets for NSCLC. This is a single-arm, open- labeled, single-stage phase II trial of cisplatin (C), docetaxel (D) and B for NSCLC. Methods: Eligibility criteria: chemo- naïve, stage IIIB wet or IV, non-squamous NSCLC, PS 0–1, no brain metastases and no history of gross hemoptysis. P received D (75 mg/m2), C (75 mg/m2), and B (15 mg/kg iv) on day 1 every 3 weeks for up to 6 cycles, followed by B 15 mg/kg alone every 3 weeks until disease progression or toxicity. Primary endpoint: PFS. Results: 50 p were enrolled (enrollment completed): 24% female, median age 60 (36–74), PS 1: 64%, adenocarcinoma: 72%; stage IV: 92%. Two p did not start treatment. Median follow-up is 5.3 months (range 0–13.6). Median number of cycles of B was 7 (range 0–18). 56% completed 6 cycles of treatment; 24% received ≥ 12 cycles of B. Most frequent grade ≥ 3 toxicities: diarrhea (14.6%), fatigue (14.6%), dyspnea (9.8%), anorexia (4.9%), alopecia (4.9%), esophagitis (4.9%), constipation (4.9%), mucositis (12.2%), proteinuria (4.9%); hematological toxicities: neutropenia (22%), febrile neutropenia (9.8%), leucopenia (14.6%), lymphopenia (4.9%). Of interest, 41.5% developed grade <3 epistaxis and 17% hypertension (1 p grade 3). One p died due to hemoptysis. 46 p were evaluable for response: 29 PRs (ORR: 63%). 18 of 48 p have experienced progression or death with a median SLP of 7.8 months (95% CI: 6.6-NR). Median OS is 13.5 months (95% CI: 12.7–13.6; 81.2% p censored); 1-year survival is 83.9% (95% CI: 67.4%-92.5%). Conclusions: Treatment with C, D and B, followed by maintenance B in 1st line of advanced non-squamous NSCLC shows an acceptable toxicity profile and promising efficacy. Final results will be presented. [Table: see text]
