5088 Background: Gimatecan, a new camptothecin derivative, is a potent topoisomerase I inhibitor, active by oral route. Methods: A multicenter two stage Simon design phase II study was performed to evaluate the single agent antitumor activity of gimatecan. Secondary objectives were safety, time to event/time related parameters, and translational medicine evaluations. Women with advanced epithelial ovarian, fallopian tube or peritoneal cancer who had progressed or recurred after prior treatment with platinum and taxanes, had a progression-free interval from last platinum-based therapy < 12 months, had measurable disease by RECIST or assessable by CA 125 (GCIG criteria) and a ECOG performance status ≤ 1 were eligible. Gimatecan 0.8 mg/m2 was administrated orally for five consecutive days every four weeks. Radiological response was assessed every two cycles. Results: From June to December 2005, 70 women [median age 61 years (range 37–79)] were treated in 10 European sites. Number of prior chemotherapy regimens was: 1 in 20, 2 in 35, 3 in 15 patients, respectively. Progression-free interval from last platinum-based therapy was 0–6 months in 51 patients and 6–12 months in 19 patients. The study is still ongoing, and to date 40 consecutive patients are assessable. Preliminary response analysis indicated a 23.5% response rate based on CA 125 (8/34) and a 10% response rate based on RECIST (3/29). Main toxicity was hematological, namely thrombocytopenia and neutropenia. Conclusions: Preliminary results suggest that oral gimatecan administered as single agent is active, with bone marrow suppression resulting at present as the main toxicity in these patients previously treated with platinum and taxanes. However, many patients are still on treatment and data need to mature to have a broader picture of activity and safety. [Table: see text]

5554 Background: Belotecan (Camtobell, Chong Keun Dang Corp, Seoul, Korea; CKD602) is a camptothecin derivative with anti-tumor properties recently developed. This phase II study was designed to evaluate the toxicity and efficacy of belotecan combined with carboplatin in patients with recurrent epithelial ovarian cancer (EOC). Methods: Belotecan 0.3 mg/m2/day (days 1–5) and carboplatin AUC 5 (day 5) were administered every 3 weeks for 6 cycles. Eligible patients had recurrent EOC, peritoneal serous cancer, or fallopian tube cancer. The primary objective was to determine response rate defined by Response Evaluation Criteria in Solid Tumors and CA-125 response; other end points included toxicities and progression free survival (PFS). Results: Until this preliminary analysis, sixteen patients had received the treatment and 13 patients were evaluable for response. Eight patients had platinum-sensitive disease (minimum treatment free interval≥6 months) and 6 had platinum-resistant disease (minimum treatment free interval <6 months). Overall response rate was 53.9%; there were 3 complete responses (23.1%), 4 partial responses (30.8%), 4 patients with stable disease (30.8%), and two patients with progressive disease (15.4%). Grade 3 and 4 hematologic toxicities included neutropenia (38%), thrombocytopenia (25%), and anemia (15%); there was one episode of febrile neutropenia. None of the patients experienced grades 3 and 4 gastrointestinal toxicities, including nausea, vomiting, and anorexia. Conclusions: The newly developed topoisomerase I inhibitor, belotecan (CKD-602), combined with carboplatin is a well-tolerated regimen with activity in recurrent EOC; further testing of this regimen is warranted.

7017 Background: Bortezomib (PS-341), a small molecule proteasome inhibitor, has single agent activity in NSCLC and potentiates Gem/Carbo in pre-clinical models in a sequence-specific manner (Mortensen, Cancer Chem Pharm, 2004). A phase I trial of Gem/Carbo + PS-341 in patients (pts) with advanced NSCLC yielded an encouraging response rate of 48%. Here we describe the results of a SWOG phase II study of this regimen in advanced NSCLC. Methods: 114 eligible chemonaive stage IV and selected stage IIIB (pleural effusion) NSCLC pts received Gem 1000 mg/m2 on days 1, 8 and Carbo AUC 5 on day 1, followed 1 hour later by PS-341 1.0 mg/m2 on days 1, 4, 8, 11, with cycles repeated every 3 weeks. Non-progressing pts could continue PS-341 alone after 4 cycles. Results: Pt characteristics: Median age: 64 years; Sex M/F = 68/46; Performance status 0/1 = 50/64; stage IIIB/IV = 13/101. Response rate: 20% (95% CI 13–29%); 66% (95% CI 56–75%) had stable disease. At a median follow-up of 13 months, progression free and median survival times were 5 months (95% CI 3.5–5.3) and 11 months (95% CI 8.2–12.5). One-year survival was 46% (95% C.I. 37–55%). Most common grade 3/4 toxicities: neutropenia (52%), thrombocytopenia (63%), and fatigue (13%). Ongoing correlative studies are examining markers of proteasome inhibition (Bcl2 family, NFKB, IKB) and hypoxia (PAI-1, VEGF, OPN, HIF-1) in tumor tissue and surrogate specimens. Conclusions: The 11 month median survival achieved with the addition of PS-341 to Gem/Carbo in this phase II study is unprecedented in prior SWOG trials in advanced NSCLC, and does not appear to be explained by altered patient characteristics. The toxicity profile of this regimen is favorable. A phase III trial of Gem/Carbo ± Bortezomib in advanced stage NSCLC is under development. Supported by CA38926, CA32102.

7643 Background: Cetuximab, a chimeric IgG1 monoclonal antibody against the external domain of the epidermal growth factor receptor (EGFR), has demonstrated single-agent activity against NSCLC. When administered in combination with carboplatin and docetaxel, a commonly used regimen for advanced NSCLC, cetuximab exhibits synergistic interaction in preclinical studies. Therefore, we conducted a phase II study to evaluate the efficacy of the combination of cetuximab, carboplatin, and docetaxel for the treatment of advanced NSCLC. Methods: Chemotherapy-naive patients = 18 years with histologically/cytologically confirmed stage IIIB (w/ effusion) or stage IV NSCLC received cetuximab (400 mg/m2 on day 1 and 250 mg/m2 on days 8 and 15) plus docetaxel (75 mg/m2 on day 1) and carboplatin (AUC=6 on day 1) every 21 days for up to 6 cycles. Thereafter, patients without evidence of disease progression (CR/PR/SD) were continued on single-agent cetuximab (250 mg/m2/week) for a maximum of 1 year or until disease progression. The primary endpoint was response rate. Results: 81 patients were enrolled and 76 are evaluable for response. Patient characteristics included: gender male/female, 43/38; median age 63 years (range 42–83); ECOG performance status 0/1/, 31/50; and stage IIIB/IV- 5/76. The median number of cycles administered was 4 (range 1–6). The response rate (CR/PR) was 14.5% (95% CI, 7.5 to 24.4), with a median progression-free survival of 4.7 months and a median overall survival of 11 months. With combination therapy, the salient grade 3/4 events were neutropenia (28%), febrile neutropenia (3.8%), hypotension (4%), hypokalemia and hypomagnesemia (5%), hypersensitivity (1%), acne-like rash (3%), peripheral neuropathy (1%), and myalgia (1%). Twenty-five patients received maintenance therapy with single-agent cetuximab (median duration of treatment was 12 weeks) and this was well tolerated. Conclusions: This large multicenter phase II study of the novel combination of cetuximab with docetaxel and carboplatin shows promising efficacy for patients with advanced and metastatic NSCLC and has an acceptable toxicity profile.

PURPOSE Docetaxel (Taxotere, Rhone-Poulenc Rorer, Antony, France) and cisplatin are two of the most active single agents used in the treatment of non-small-cell lung cancer (NSCLC). A recently reported phase I study of the combination of docetaxel and cisplatin recommended a dose of 75 mg/m2 of both drugs every 3 weeks for subsequent phase II study. PATIENTS AND METHODS Eligible patients were aged 18 to 75 years with a World Health Organization (WHO) performance status < or = 2 and life expectancy > or = 12 weeks, with metastatic and/or locally advanced NSCLC proven histologically or cytologically. Patients were not permitted to have received prior chemotherapy, extensive radiotherapy, or any radiotherapy to the target lesion and must have had measurable disease. Concurrent treatment with colony-stimulating factors (CSFs) or prophylactic antibiotics was not permitted. Docetaxel (75 mg/m2) in 250 mL 5% dextrose was given intravenously (i.v.) over 1 hour immediately before cisplatin (75 mg/m2) in 500 mL normal saline given i.v. over 1 hour in 3-week cycles. Premedication included ondansetron, dexamethasone, promethazine, and standard hyperhydration with magnesium supplementation. RESULTS A total of 47 patients, two thirds of whom had metastatic disease, were entered onto this phase II study. The majority of patients were male (72%) and of good (WHO 0 to 1) performance status (85%). All 47 patients were assessable for toxicity and 36 were for response. Three patients were ineligible and eight (17%) discontinued treatment because of significant toxicity. In assessable patients, the overall objective response rate was 38.9% (95% confidence limits [CL], 23.1% to 56.5%), 36.1% had stable disease, and 25% progressive disease. On an intention-to-treat analysis, the objective response rate was 29.8%. Median survival was 9.6 months and estimated 1-year survival was 33%. Significant (grade 3/4) toxicities included nausea (26%), hypotension (15%), diarrhea (13%), and dyspnea mainly related to chest infection (13%). One patient experienced National Cancer Institute (NCI) grade 3 neurosensory toxicity after eight cycles. Grade 3/4 neutropenia was common and occurred in 87% of patients, but thrombocytopenia > or = grade 3 was rare (one patient). Significant (grade 3/4) abnormalities of magnesium levels were common (24%). Febrile neutropenia occurred in 13% of patients and neutropenic infection in 11%, contributing to two treatment-related deaths. No neutropenic enterocolitis or severe fluid retention was reported. CONCLUSION Compared with other active regimens used in this setting, the combination of docetaxel and cisplatin in advanced NSCLC is an active regimen with a similar toxicity profile to other combination regimens.

Abstract BACKGROUND Patients with relapse of recurrent glioma have a poor outcome and limited treatment options. The aim of this study is to investigate the clinical benefit and tolerability of weekly intravenous administration of carboplatin-based monotherapy in adult glioma patients who had progressed from previous chemotherapy lines based on temozolomide and nitrosoureas MATERIAL AND METHODS This was a single arm, Phase II study. Eligibility criteria included progressive or recurrent malignant glioma after radiotherapy and chemotherapy-based treatments and Karnofsky Performance Status (KPS) > 60. RESULTS Thirty-two patients (median age: 43.5 y) were enrolled to receive weekly carboplatin monotherapy in intravenous mode of administration. The median duration of response was 7.3 months with an overall disease control rate of 31.3%. Median progression-free survival (PFS) was 2.3 months while overall survival (OS) was 5.5 months. Patients achieving clinical benefit exhibited a longer PFS (4.6 vs 1.5 months; p>0.001) and OS (7.9 vs 3.2 months; p=0.041) compared to those not achieving clinical benefit. CONCLUSION Our findings show that single agent, weekly, intravenous carboplatin may have a role in the treatment patients with recurrent malignant glioma

Purpose This phase II study evaluated the activity of combined treatment with interferon alfa-2b and sorafenib, a Raf and multiple receptor tyrosine kinase inhibitor, in patients with advanced renal carcinoma. Patients and Methods Eligible patients had metastatic or unresectable renal carcinoma with a clear-cell component, no prior systemic therapy, performance status 0 to 1, and measurable disease. Treatment consisted of interferon alfa-2b 10 × 106 U subcutaneously three times weekly and sorafenib 400 mg orally bid. The primary end point was confirmed Response Evaluation Criteria in Solid Tumors response rate. Results Twelve (19%) of 62 assessable patients achieved an objective confirmed response. An additional 31 (50%) had an unconfirmed partial response or stable disease as best response. The median progression-free survival was 7 months (95% CI, 4 to 11 months). The most common adverse events were fatigue, anorexia, anemia, diarrhea, nausea, rigors/chills, leukopenia, fever, and transaminase elevation. Von Hippel-Lindau gene mutations were detected in four (22%) of 18 archival tumor specimens. Conclusion The confirmed response rate for the combination of sorafenib and interferon in advanced renal carcinoma is greater than expected with either interferon or sorafenib alone. The toxicity of this combination is dominated by adverse events common to interferon that limit further development of this regimen.

PURPOSE Docetaxel and cisplatin has documented single-agent activity and different toxicity profiles in patients with metastatic urothelial cancer. We performed a phase II study in which docetaxel was combined with cisplatin to evaluate response rate, toxicity, and survival. PATIENTS AND METHODS Eligibility criteria included performance status (World Health Organization [WHO]) less than 3; normal bone marrow, liver, and renal function; and no concurrent malignancy or symptomatic peripheral neuropathy. Docetaxel (Taxotere; Rhône-Poulenc Rorer, Paris, France) 75 mg/m2 was combined with cisplatin 75 mg/m2 every third week. Patients received premedication with prednisolone and clemastine. RESULTS A total of 25 patients were assessable for response and toxicity. Median age was 64 years; five patients had locoregional disease only and 20 had metastatic disease. Response was achieved in 15 patients (60%; 95% confidence interval [CI], 39% to 79%), including seven patients (26%) who achieved a complete response. Overall median survival time was 13.6 months (range, 1.5 to 26.4+). The most frequent toxicity was nausea and vomiting (80% of patients). Neutropenia grade 3 or 4 was observed in 56% of patients, but only one had febrile neutropenia. Mucositis and diarrhea were encountered in 13% of cycles, mostly grade 1 or 2. Peripheral neuropathy and skin changes grade 1 and 2 were observed in 76% and 36%, respectively. Fluid retention and hypersensitivity reactions were infrequent and mild. CONCLUSION The combination of docetaxel and cisplatin is effective and feasible in patients with metastatic urothelial cancer with a manageable safety profile.

Abstract Topoisomerase enzymes are critical components of genomic replication and function to minimize torsional stress on DNA. Inhibition of topoisomerase function leads to DNA strand breaks followed by apoptosis. In malignant lymphomas, topo II inhibitors (anthracyclines, epidophyllotoxins) are part of many active regimens, and topo I inhibitors (camptothecins) show modest single agent activity. Supported by preclinical data, we hypothesized that the sequential administration of a topo II inhibitor followed by a topo I inhibitor would be potentially synergistic, with enhanced cytotoxicity of the topo I inhibitor due to increased target enzyme levels following topo II inhibition. The treatment regimen consisted of doxorubicin 25 mg/m2 IV on day 1 and topotecan 1.75 mg/m2/d IV on days 3–5, repeated at 21 day intervals. The primary objective of this phase II study was to determine the overall response rate, time to progression, and toxicity in patients with relapsed/refractory aggressive NHL. Eligible patients had recurrent or refractory aggressive NHL, no prior camptothecins, and limited prior anthracycline exposure (<400 mg/m2 prior doxorubicin; <96 mg/m2 prior mitoxantrone), and an ejection fraction ≥ 45% at baseline. Results: From July 2000 to August 2003, 26 patients were registered. One registered patient did not start protocol treatment and is excluded from analysis. Of 22 patients with a known histologic subtype, 18 had diffuse large B cell lymphoma and there was one case each of Burkitt’s, follicular grade III, anaplastic large cell, and anaplastic large cell, Hodgkin’s like lymphoma. The median age was 58 (range 23–74) years. All patients were heavily pretreated with a median of 2 (range 1–5) prior regimens, including 5 patients who had a prior stem cell transplant (SCT). A median of 2 cycles (range 1–6) were administered. Five patients (20%, 95% CI 0.07, 0.42) responded with 1 (4%) complete remission (CR) and 4 (16%) partial remissions (PR); an additional 3 (12%) patients had stable disease. 12 (48%) patients progressed during or after the first cycle and 5 (20%) progressed after the second cycle. The one patient achieving a CR had Burkitt’s lymphoma, and received a total of 6 cycles; this patient remains in remission 21 months following the end of treatment. Of the PR patients, 2 remain in PR at 1.5 and 12 months following therapy, and 2 patients have progressed at 1.5 and 6 months. Interestingly, 4 of the 5 responders had prior SCT. The main toxicity was hematologic, with 14 (63%) and 9 (41%) patients having grade 3 or 4 neutropenia and thrombocytopenia, respectively. Three patients had febrile neutropenia. There were no treatment-related deaths. Seven patients remain alive and 18 patients have died. The median follow-up time for surviving patients is 14 (range 7–27) months. The median event-free survival is 1.3 months and the median overall survival is 3.6 months. The combination of doxorubicin and topotecan is well-tolerated and has modest activity in relapsed/refractory NHL, with an occasional patient having a prolonged remission.

Abstract Tosedostat (TSD, CHR-2797) is an aminopeptidase inhibitor that selectively depletes amino acid pools in malignant cells, resulting in anti-proliferative, pro-apoptotic and antiangiogenic effects. In a phase I study, treatment with TSD resulted in complete remission in a number of refractory AML patients. The primary objective of this phase II study was to determine whether TSD was a sufficiently effective therapy to warrant pivotal studies. Methods. This was an open label, single agent, phase II study to assess clinical activity of TSD in elderly and/or previously treated patients with AML/MDS. Patients were treated with once daily oral doses of the maximum acceptable dose (130 mg) of TSD for up to 84 days. Further treatment was allowed if, in the opinion of the investigator, this was considered to be beneficial. Clinical responses were assessed by monthly bone marrow aspirates and weekly hematological assessments. Results. Of the 41 TSD-treated patients with AML (n=38) or MDS (n=3), who were enrolled between March and October 2007, 27 were male, 14 female, with a mean age of 67 years (range 34–82). The median performance status (ECOG) at baseline was 1 (range 0–2). Twelve (31.6%) AML patients and 2 (66.7%) MDS patients were chemotherapy naïve, and 9 (23.7%) AML patients had either secondary disease or adverse cytogenetics. For 16 (39%) patients, treatment with TSD was a second or later salvage attempt. Thirty two patients (30 AML, 2 MDS-RAEB1 and 2) received ≥28 days treatment, and 21 (51.2%) patients completed the formal 84-day study period (19 AML, 2 MDS). Nine (22%) of the patients (7 AML, 2 MDS) continued treatment with TSD after 84 days, and 6 (15%) patients were on TSD in total for more than 6 months (4 AML, 2 MDS). Ten (26.3%) of the AML patients responded to treatment; amongst these, 2 patients received TSD as 2nd/3rd salvage therapy, and a further 2 patients did not show a complete response (CR) after 2 previous induction courses of chemotherapy. Three AML patients achieved a CR (< 5% blasts in bone marrow), of whom 2 were in durable remission (232 days, continuing*; 171 days), and 7 had a partial response (PR, 5–15% blasts) lasting approximately 1–3 months. Two (66.7%) of the MDS patients also responded to treatment with TSD; these patients maintained stable disease for more than 6 months. All responders (CR, PR and SD) were >60 years at the time of the first dose. Median overall survival in AML patients was 130 days (range 8 – 478 days*). The most frequently reported adverse events were: fatigue (61%), thrombocytopenia (49%), pyrexia (39%), peripheral edema (39%) and diarrhea (34%); 9 (22%) patients withdrew due to drug related toxicity. TSD had no effect on hemoglobin or neutrophils. Conclusions. This study in patients with advanced AML/MDS with adverse prognosis demonstrates the anti-leukemic activity of TSD in elderly AML patients, as measured by CR and decreases in leukemic blasts. In addition, 2 relapsed high risk MDS patients achieved disease stabilization. TSD at 130mg qd is also very well tolerated over a long period of exposure (6–10 months). These results support further pivotal studies with TSD in elderly AML and MDS patients.
