Phase I safety and pharmacokinetics of BAY 43-9006 administered for 21 days on/7 days off in patients with advanced, refractory solid tumours

BAY 43-9006 is a novel dual-action Raf kinase and vascular endothelial growth factor receptor (VEGFR) inhibitor that targets tumour cell proliferation and tumour angiogenesis. This Phase I study was undertaken to determine the safety profile, maximum tolerated dose (MTD), dose-limiting toxicities (DLTs), pharmacokinetics, and tumour response profile of oral BAY 43-9006 in patients with advanced, refractory solid tumours. BAY 43-9006 was administered daily for repeated cycles of 21 days on/7 days off. A total of 44 patients were enrolled at doses from 50 to 800 mg b.i.d. Pharmacokinetic profiles of BAY 43-9006 in plasma were determined during the first treatment cycle. The most frequently reported adverse events over multiple cycles were gastrointestinal (75%), dermatologic (71%), constitutional (68%), pain (64%), or hepatic (61%) related. A MTD of 400 mg b.i.d. BAY 43-9006 was defined. BAY 43-9006 was absorbed rapidly; steady-state conditions were reached within 7 days. BAY 43-9006 exposure increased nonproportionally with increasing dose. In all, 32 patients were evaluated for tumour response: 15 patients showed tumour progression, 16 patients experienced stable disease (>6 months in eight patients), and one patient with renal cell carcinoma achieved a partial response. BAY 43-9006 given for 21 days with 7 days off treatment was safe, well tolerated, and showed antitumour activity.

Pioneering Quality Assessment in European Cancer Centers: A Data Analysis of the Organization for European Cancer Institutes Accreditation and Designation Program

PURPOSE In order to improve the quality of care in Cancer Centers (CC) and designate Comprehensive Cancer Centers (CCCs), the Organization for European Cancer Institutes (OECI) launched an Accreditation and Designation (A&D) program. The program facilitates the collection of defined data and the assessment of cancer center quality. This study analyzes the results of the first 10 European centers that entered the program. METHODS The assessment included 927 items divided across qualitative and quantitative questionnaires. Data collected during self-assessment and peer-review from the 10 first participating centers were combined in a database for comparative analysis using simple statistics. Quantitative and qualitative results were validated by auditors during the peer review visits. RESULTS Volumes of various functions and activities dedicated to care, research, and education varied widely among centers. There were no significant differences in resources for radiology, radiotherapy, pathologic diagnostic, and surgery. Differences were observed in the use of clinical pathways but not for the practices of holding multidisciplinary team meetings and conforming to guidelines. Regarding human resources, main differences were in the composition and number of supportive care and research staff. All 10 centers applied as CCCs; five obtained the label, and five were designated as CCs. CONCLUSION The OECI A&D program allows comparisons between centers with regard to management, research, care, education, and designation as CCs or CCCs. Through the peer review system, recommendations for improvements are given. Assessing the added value of the program, as well as research and patient treatment outcomes, is the next step.

Breast cancer therapies in development. A review of their pharmacology and clinical potential.

SummaryAlthough the management of breast cancer has improved over the past few decades, it remains an important challenge for the clinician.Cytotoxic chemotherapy and hormonotherapy, when given in the adjuvant setting, have a definitive though modest impact on the outcome of early-stage breast cancer. In metastatic disease, these therapies help to provide substantial palliation of symptoms but have a limited impact on survival.The discovery of vinorelbine and the taxanes, paclitaxel and docetaxel, certainly represented the most encouraging clinical development of the 1980s in breast cancer therapy. Several other new cytotoxic agents have been recognised for their potential in the treatment of this disorder. Many of them are only in a very early phase of their clinical development and it remains to be proven that they will have a major role in daily practice in the near future.In terms of hormonal treatment, new aromatase inhibitors and new anti-estrogens have been developed and, to date, show equivalent efficacy compared with the more classical hormonal agents. Some of them may be substantially better tolerated.Our increasing understanding of the process of metastasis, of the mechanisms of resistance of cancer cells and of cell transformation, proliferation and differentiation is now translating into several promising new treatment strategies for the management of breast cancer patients. Thus, the success of these promising new therapeutic agents and strategies, which have been identified over the past few years and are in various stages of clinical development, will certainly depend in part on their proper evaluation in well designed clinical trials.

Potential Role of Oral Anthracyclines in Older Patients with Cancer

SummaryTwo anthracycline analogues, idarubicin and menogaril, have acceptable bioavailability via the oral route of administration.Encouraging antitumour activity of oral idarubicin has been reported in breast cancer, non-lymphocytic leukaemia, non-Hodgkin’s lymphoma and myeloma. The outlook for menogaril is less clear, given the modest antitumour activity reported so far.Although the oral formulations of idarubicin and menogaril remain investigational, they represent a step forward in the direction of developing new active anticancer drugs with oral bioavailability.Further prospective studies of the orally-active anthracyclines in elderly patients with cancer are justified. These studies should address specific issues such as optimal dosage regimens as a function of ‘physiological age’, and quality of life.

Phase I clinical and pharmacokinetic trial of oral menogaril administered on three consecutive days

Eighteen adult patients with solid tumors were treated with oral menogaril, a new anthracycline antibiotic active against human breast cancer after intravenous administration. The drug was given orally on 3 consecutive days every 4 weeks at doses ranging from 50 to 175 mg/m2/day. Reversible and dose-related leukopenia was the dose-limiting toxicity. Thrombocytopenia was less frequent. Hematologic toxicity was maximal usually 2 weeks after treatment and recovery usually occurred within 4 weeks. At doses from 50 to 150 mg/m2/day, non-hematologic side-effects of oral menogaril were infrequent and mild and consisted of nausea and vomiting (one patient), alopecia (two patients), mucositis (two patients) and liver function test abnormalities (three patients). The single patient treated at a daily dose of 175 mg/m2/day developed grade IV leucothrombocytopenia, with fever and gastrointestinal bleeding. This was followed by heart failure and the patient died from multisystem organ failure. Peak plasma concentrations of menogaril ranged from 0.043 to 0.409 microM and were linearly correlated with the dose. Similarly, the area under the plasma concentration versus time curve varied from 0.33 to 9.59 microM X h and was linearly correlated with the dose. The mean harmonic half-life was 11.3 +/- 6.4 h. A comparison of the data from the present trial and our previous study with intravenous menogaril indicates a bioavailability of 32 +/- 12%. There was an excellent relationship between the white blood cell decrease (as a percentage of the pretreatment value) and several pharmacokinetic parameters; the best correlation was obtained with the plasma concentration of menogaril at 4 h after treatment. A dose of 150 mg/m2/day for 3 consecutive days is recommended for phase II trials with oral menogaril but the bioavailability of the drug should be monitored carefully and, more specifically, the concept of a pharmacokinetic adjustment of the dose of menogaril should be evaluated prospectively.

Results of the Belgian expanded access program of eribulin in the treatment of metastatic breast cancer closely mirror those of the pivotal phase III trial

BACKGROUND Eribulin is a non-taxane microtubule dynamics inhibitor that showed a survival benefit versus treatment of physicians choice in a phase III trial enrolling patients with metastatic breast cancer (MBC). METHODS The E7389-G000-398 trial was designed to provide eribulin to MBC patients pre-treated with anthracylines, taxanes and capecitabine. Patient characteristics, efficacy and safety data were collected prospectively. Efficacy and survival analyses were performed using retrospectively collected data of patients treated at a single institution. RESULTS One hundred fifty-four patients were enrolled and the median number of previous lines of chemotherapy was 4. The most frequent adverse events were fatigue/asthenia (74%), alopecia (55%), peripheral neuropathy (46%) and neutropenia (43%). Objective response rate (ORR) was 24% in the evaluable population and 14% in patients pre-treated with both taxanes and vinorelbine. In patients with oestrogen receptor (ER)+/human epidermal growth factor receptor 2 (HER2)- MBC, response rate was 29% and 21% with triple-negative disease. Activity was minimal in HER2+ MBC treated with eribulin monotherapy (14% ORR). Median progression-free survival was 3.2 months. Median overall survival was 11.3 months; 77% of patients were alive at 6 months and 43% at 12 months. CONCLUSION Eribulin was active in MBC patients with a high tumour burden and predominant visceral disease. Safety profile was similar to what was reported in the phase III trials. Prophylactic granulocyte colony-stimulating factor administration allowed optimal dose intensity and could have contributed to the recorded response rate. Activity is sustained after treatment with taxanes and vinorelbine. The recently investigated combination of eribulin and trastuzumab should lead to higher activity in HER2-positive MBC.

Phase I Clinical Trial of Oral Menogaril Administered on Three Consecutive Days

Eighteen adult patients with solid tumors were treated with oral menogaril, a new anthracycline antibiotic active against human breast cancer after intravenous administration. The drug was given orally on 3 consecutive days every 4 weeks at doses ranging from 50 to 175 mg/m2/day. Reversible and dose-related leukopenia was the dose-limiting toxicity. At doses from 50 to 150 mg/m2/day, non-hematologic side effects of oral menogaril were unfrequent and mild and consisted of nausea and vomiting (1 patient), alopecia (2 patients), mucositis (2 patients) and liver function test abnormalities (3 patients). The only patient treated at a daily dose of 175 mg/m2 developed grade IV leukothrombocytopenia, with fever and gastrointestinal bleeding. This was followed by heart insufficiency and the patient died from multisystem organ failure. A dose of 150 mg/m2/day for 3 consecutive days is recommended for phase II trials with oral menogaril.

Participation of Italian Cancer Centres of the Alleanza Contro Il Cancro (ACC) in the Organisation of European Cancer Institutes (OECI) Accreditation and Designation program: A successful first national initiative

The Organisation of European Cancer Institutes (OECI) launched a program for accreditation and designation (A&D) of cancer centers in Europe based on voluntary participation in 2008. In 2012, the Italian Ministry of Health decided to fund cancer centers in Italy, members of the Alleanza Contro il Cancro (ACC), to go through the OECI accreditation program. Ten centers participated in the program and 10 completed the full cycle of the OECI A&D process in consecutive series over a 2-year period. The process was successfully completed within the planned timeline and the overall findings were presented to the Italian Ministry of Health and representatives of all the participating centers in November 2015. The program had a considerable team-building effect, which will likely continue as the improvement plans are implemented. Centers fed back to OECI that the A&D program had led to better formal organization of multidisciplinary teams (MDTs) and cancer care pathways, and had helped them to harmonize the integration of research into clinical practice. Centers also concluded that they benefited from recognition through an international accreditation system, and that it had led to them developing better patient information and involvement. The importance of the improvement plans that each center had to produce following the audit reviews cannot be underestimated. The OECI concludes that implementation of the A&D program at the national level is feasible despite national peculiarities related to health planning and organization in each member state. This is a good example of an EU project working well, with member states helping each other and learning from best practice, to improve the overall quality of cancer care and research and to establish consistency. The initial accreditation is the first part of an ongoing process of improving comprehensive cancer care, integrating bench to bedside.The Organisation of European Cancer Institutes (OECI) launched a program for accreditation and designation (A&D) of cancer centers in Europe based on voluntary participation in 2008.
