Vascular disrupting agents: a novel mechanism of action in the battle against non-small cell lung cancer.
Targeting vasculature, essential in oxygen and nutrient supply, represents a new frontier in the treatment of cancer. Apart from angiogenesis inhibitors that compromise the formation of new blood vessels, a second class of vascular disrupting agents (VDAs) targets endothelial cells and pericytes of the already established tumor vasculature, resulting in tumor ischemia and necrosis. VDAs have been divided into two types: ligand-directed VDAs and small molecules. Ligand-directed VDAs consist of targeting and effector moieties that are linked together. Their clinical efficacy appears limited because of cost and a lack of specificity and toxicity. Small molecules include two classes: the synthetic flavonoids, which work through induction of local cytokine production, and the tubulin-binding agents. The aim of this review is to discuss the hypothesized molecular mechanisms of action of VDAs and their early preclinical and clinical results, emphasizing ASA404, combretastatin A-4 disodium phosphate, ABT-751, and NPI-2358, reported in the treatment of non-small cell lung cancer, which is the leading cause of cancer death worldwide, and also to discuss future developments in this cancer population.

[Tumor vasculature as a therapeutic target in non-small cell lung cancer].
Despite developments in conventional (chemo)radiotherapy and surgery, survival of non-small cell lung cancer (NSCLC) patients remains poor. Treatments with targeted molecular drugs offer novel therapeutic strategies. Bevacizumab, a recombinant anti-vascular endothelial growth factor (VEGF) antibody, is the antiangiogenic drug at the most advanced stage of development in the therapy of NSCLC. However, a number of questions and future challenges relating to the use of bevacizumab in NSCLC remain. Furthermore, novel agents targeting the pre-existing NSCLC vasculature (i.e. vascular disrupting agents, VDAs) or multiple tyrosine kinase inhibitors have emerged as unique drug classes delivering promising results in several preclinical and clinical studies. Herein, we review the most recent data using these novel targeted agents either alone or in combination with chemotherapy in NSCLC.

[Antimicrotubule agents].
Microtubules are among the most strategic subcellular targets of anticancer agents. Recently, new antimicrotubule agents have been introduced to clinical cancer chemotherapy. Navelbine is a new derivative of vinca alkaloids, which especially has an activity against NSCLC. Unlike classical anti-microtubules agents like colchitine and vinca alkaloids, which induce depolymerization of microtubules, taxol has an unique mechanism of action which induces tubulin polymerization. Taxotere, an analogue of taxol is slightly more active as a promoter of tubulin polymerization than Taxol. E7010 is a novel sulfonamide that inhibits tubulin polymerization. Results of preclinical and clinical studies of these agents are reviewed. Topics: Aminophenols; Animals; Antineoplastic Agents; Carcinoma, Non-Small-Cell Lung; Docetaxel; Humans; Leukemia, Experimental; Lung Neoplasms; Mice; Microtubules; Paclitaxel; Sulfonamides; Taxoids; Vinblastine; Vinorelbine | 1993 |

A phase I trial and in vitro studies combining ABT-751 with carboplatin in previously treated non-small cell lung cancer patients.
ABT-751 is a novel antimitotic agent that exerted cytotoxic effects in preclinical studies. Carboplatin has efficacy in treating advanced non-small cell lung cancer (NSCLC) in combination with other drugs.. Lung cancer cell lines were treated with ABT-751 and/or carboplatin to investigate their impact on cell growth. A phase I study with an expansion cohort was conducted in previously treated NSCLC patients. The primary objective was the maximum tolerated dose (MTD); secondary objectives were objective response rates, median survival, time to tumor progression, dose-limiting toxicities (DLTs), and pharmacodynamic evaluation of buccal swabs.. Combining ABT-751 with carboplatin significantly reduced growth and induced apoptosis of lung cancer cell lines. Twenty advanced NSCLC patients were enrolled. MTD was ABT-751 125 mg orally twice daily for 7 days with carboplatin AUC 6. DLTs included fatigue, ileus, neutropenia and pneumonitis. Two patients had confirmed partial responses. Median overall survival was 11.7 months (95% CI 5.9-27.0). Time to tumor progression was 2.8 months (95% CI 2.0-2.7). Four of 6 patients showed decreased cyclin D1 protein in posttreatment versus pretreatment buccal swabs.. Combining ABT-751 with carboplatin suppressed growth of lung cancer cell lines and had modest clinical antitumor activity in advanced NSCLC previously treated predominantly with carboplatin. Further studies of this combination are not recommended while investigations of biomarkers in different patient populations, alternative schedules and combinations may be pursued.

Phase I/II study of pemetrexed with or without ABT-751 in advanced or metastatic non-small-cell lung cancer.
ABT-751 is an antimitotic and vascular disrupting agent with potent preclinical anticancer activity. We conducted a phase I and randomized double-blind phase II study of pemetrexed with ABT-751 or placebo in patients with recurrent advanced or metastatic non-small-cell lung cancer (NSCLC).. One hundred seventy-one patients received intravenous pemetrexed 500 mg/m(2) day 1 and oral ABT-751 or placebo days 1 to 14 of 21-day cycles. The primary end point was progression-free survival (PFS). Secondary end point included overall survival (OS); pharmacokinetic and pharmacodynamic parameters were also analyzed.. The recommended phase II dose of ABT-751 with pemetrexed is 200 mg. Fatigue, constipation, anemia, nausea, and diarrhea were the most common toxicities in both study arms. No pharmacokinetic interactions were observed. Median PFS in the ABT-751 arm was 2.3 months versus 1.9 for placebo (P = .819, log-rank) for the intention-to-treat population. However, differences in PFS (P = .112, log-rank) and OS (P = .034, log-rank; median 3.3 v 8.1 months) favoring ABT-751 were seen in the squamous NSCLC subgroup. Baseline circulating tumor cell concentrations were predictive of improved OS (P = .013). Changes from baseline of greater than 20% in plasma levels of placenta growth factor (P = .056), squamous cell carcinoma antigen (P = .03), and cytokeratin 19 fragment antigen 21-1 (P = .01) were markers best associated with improved OS.. Addition of ABT-751 to pemetrexed is well-tolerated, but does not improve outcome in unselected patients with recurrent NSCLC. ABT-751 may have therapeutic potential in squamous NSCLC. Exploratory cellular and molecular analyses in this study identified biomarkers that may correlate with survival.

A phase II study of ABT-751 in patients with advanced non-small cell lung cancer.
To determine the tolerability and efficacy of ABT-751, an oral antimitotic agent that inhibits polymerization of microtubules, in patients with advanced taxane-refractory non-small cell lung carcinoma (NSCLC).. Eligibility was limited to patients with recurrent or metastatic NSCLC who had received one to two cytotoxic chemotherapy regimens, had a performance status of zero to one, and adequate organ function. Treatment included ABT-751 200 mg daily for 21 consecutive days, followed by 7 days off drug. Objectives were to determine response rate, time to tumor progression, survival, and tolerability of ABT-751.. All 35 enrolled patients were assessable for survival, response, and tolerability. Median time to tumor progression and overall survival were 2.1 and 8.4 months, respectively. The objective response rate was 2.9%. One patient achieved a partial response that was ongoing 567 days after initial documentation. Treatment was well tolerated; fatigue, constipation, and dehydration were the only treatment related, grade three adverse events occurring in more than one patient. Incidence of grade 3/4 hematologic and blood chemistry toxicities was acceptable, and ABT-751 was not associated with myelosuppression.. ABT-751 associated toxicity was acceptable. The median time to progression and overall survival as demonstrated for ABT-751 were comparable to other agents considered active in this patient population and to current treatments approved for second-line NSCLC. The novel antimitotic targeting of ABT-751 in combination with the compound's acceptable nonmyelosuppressive toxicity profile and efficacy similar to agents currently in use in this setting, warrant further evaluation of this compound in combination with other cytotoxic agents in advanced NSCLC.

Chemosensitization and radiosensitization of human lung and colon cancers by antimitotic agent, ABT-751, in athymic murine xenograft models of subcutaneous tumor growth.
ABT-751 is an orally active antimitotic agent that is currently in Phase II clinical trials. This agent binds to the colchicine site on ss-tubulin and inhibits polymerization of microtubules. This disruption of microtubule dynamics leads to a block in the cell cycle at the G2/M phase, and promotes apoptosis. ABT-751, as a single agent, has antitumor activity against a series of xenograft models including non-small cell lung cancer (NSCLC) and colon cancer. The current studies were conducted to determine whether ABT-751 enhances antitumor activity of standard cytotoxic therapies currently in clinical use.. Efficacy of ABT-751, in combination with cisplatin, 5-FU, and radiation, was evaluated in the Calu-6 NSCLC, HT-29 colon, and HCT-116 colon carcinoma xenograft models, respectively. Tumor-bearing athymic mice were treated with ABT-751 orally once a day at 75 or 100 mg/kg/day on a 5-days-on, 5-days-off schedule for two cycles.. Efficacy of ABT-751 at 100 mg/kg/day was tested in combination with cisplatin at its maximum tolerable dose (MTD) (10 mg/kg/day, i.p. x1) in Calu-6 tumor-bearing athymic mice. The percent treated/control (%T/C) tumor volume ratios on day 38 were 35, 37, and 6, and the percent tumor growth delay (%TGD) values were 71, 65, and 188 for cisplatin, ABT-751 and the combination groups, respectively. HT-29 colon tumors were used to test ABT-751 in combination with an MTD of 5-FU, 30 mg/kg/day, i.p., q.d. x5. The %T/C ratios on day 38 were 22, 28, and 5 and the %TGD values were 75, 75, and 150 for 5-FU, ABT-751, and the combination groups, respectively. Treatment of HCT-116 colon carcinoma tumors with ABT-751, concurrent with the radiation treatment, was able to both enhance radiation-induced tumor regression, and delay the time to recurrence and progression. Growth curves allowed calculation of enhancement of radiation-induced growth delay (defined as the additional time required for a treated tumor to reach four times its original size) of 2, 9, and 12 days, for ABT-751 alone, radiation alone, and the combination, respectively.. Collectively, these studies demonstrate that ABT-751 enhanced efficacy of standard cytotoxic therapies in a variety of tumor xenograft models, and that enhancement was at least additive in all systems.

Mechanism of action of E7010, an orally active sulfonamide antitumor agent: inhibition of mitosis by binding to the colchicine site of tubulin.
E7010 (N-[2-[(4-hydroxyphenyl)amino]-3-pyridinyl]-4-methoxybenzenesulfonami de), an orally active sulfonamide antitumor agent that is currently in a Phase I clinical trial, showed rather consistent growth-inhibitory activities against a panel of 26 human tumor cell lines (IC50 = 0.06-0.8 microg/ml), in contrast to vincristine (VCR; IC50 = 0.0002-0.04 microg/ml), 5-fluorouracil (IC50 = 0.2-30 microg/ml), Adriamycin (IC50 = 0.002-0.7 microg/ml), mitomycin C (IC50 = 0.007-3 microg/ml), 1-beta-D-arabinofuranoxylcytosine (IC50 = 0.005 to >30 microg/ml), camptothecin (IC50 = 0.002-0.4 microg/ml), and cisplatin (IC50 = 0.5-20 microg/ml). It caused a dose-dependent increase in the percentage of mitotic cells in parallel with a decrease in cell proliferation, like VCR. It also showed a dose-dependent inhibition of tubulin polymerization, which correlated well with the cell growth-inhibitory activity. 14C-labeled E7010 bound to purified tubulin, and this binding was inhibited by colchicine but not by VCR. However, its binding properties were different from those of colchicine, as well as those of VCR. E7010 was active against two kinds of VCR-resistant P388 cell lines, one of which showed multidrug resistance due to the overexpression of P-glycoprotein (resistant to Taxol), and the other did not show multidrug resistance (sensitive to Taxol). Furthermore, four E7010-resistant P388 cell lines showed no cross-resistance to VCR, a different pattern of resistance to podophyllotoxin, and collateral sensitivity to Taxol. Therefore, E7010 is a novel tubulin-binding agent that has a wider antitumor spectrum than VCR and has different properties from those of VCR or Taxol.

In vivo tumor growth inhibition produced by a novel sulfonamide, E7010, against rodent and human tumors.
The search for compounds active against solid tumors has led us to the discovery of a novel sulfonamide, E7010 (N-[2-[(4-hydroxyphenyl)amino]-3-pyridinyl]-4- methoxybenzenesulfonamide), which inhibits tubulin polymerization. When administered orally, E7010 showed good antitumor activity against various rodent tumors and human tumor xenografts. In tests on mouse tumor, E7010, administered in doses of 25-100 mg/kg daily for 8 days, inhibited the growth of colon 38 carcinoma inoculated s.c. in mice by 60-99%. E7010 was active against s.c. inoculated M5076 fibrosarcoma (75% tumor growth inhibition), s.c. inoculated Lewis lung carcinoma (84% increase in life span), and i.p. inoculated P388 leukemia (118% increase in life span). In a test on rat tumor, E7010 inhibited the growth of SST-2 mammary carcinoma inoculated s.c. in rats by 84%. In tests on s.c. inoculated human tumor xenografts, E7010, when administered orally, showed a broad spectrum of activity. E7010 inhibited the growth of: four kinds of gastric cancer, H-81, H-111, SC-2, and SC-6 by 60-78%; three kinds of colon cancer, H-143, COLO320DM, and WiDr by 58-83%; three kinds of lung cancer, LC-376, LC-6, and LX-1 by 63-82%; and two kinds of breast cancer, H-31 and MX-1 by 79-87%. In studies on drug-resistant P388 leukemia, E7010 was effective against vincristine-resistant P388, cisplatin-resistant P388, and 5-fluorouracil-resistant P388 sublines in mice. Because of its good activity against rodent tumors and human tumor xenografts, E7010 is currently undergoing Phase I clinical trials.
