Abstract
PURPOSE To test the concept of taxane sequencing in combined-modality therapy, this phase II trial (S9504) evaluated consolidation docetaxel after concurrent chemoradiotherapy in patients with pathologically documented stage IIIB non-small-cell lung cancer (NSCLC). Results were compared with those of the predecessor study (S9019) with identical eligibility, staging criteria, and treatment, excepting docetaxel consolidation. PATIENTS AND METHODS Treatment consisted of cisplatin 50 mg/m2 on days 1, 8, 29, and 36, etoposide 50 mg/m2 on days 1 through 5 and 29 through 33, and concurrent thoracic radiotherapy (total dose of 61 Gy). Consolidation docetaxel started 4 to 6 weeks after chemoradiotherapy at an initial dose of 75 mg/m2. RESULTS Stage subsets (tumor-node-metastasis system) in 83 eligible patients were as follows: T4N0/1, 31 patients (37%); T4N2, 22 patients (27%), and T1-3N3, 30 patients (36%). Concurrent chemoradiotherapy was generally well tolerated, but two patients died from probable radiation-associated pneumonitis. Neutropenia during consolidation docetaxel was common (57% with grade 4) and most frequent during escalation to 100 mg/m2. Median progression-free survival was 16 months, median survival was 26 months, and 1-, 2-, and 3-year survival rates were 76%, 54%, and 37%, respectively. Brain metastasis was the most common site of failure. In S9019, median survival was 15 months and 1-, 2-, and 3-year survival rates were 58%, 34%, and 17%, respectively. CONCLUSION Consolidation docetaxel after concurrent chemoradiotherapy in stage IIIB NSCLC is feasible and generally tolerable, and results compare favorably with the predecessor trial S9019. Nevertheless, this study remains hypothesis-generating and does not provide definitive evidence of the benefit of this approach. Phase III trials evaluating the S9504 regimen have been initiated to validate these results.

Abstract
PURPOSE This phase II clinical study evaluated the efficacy of pemetrexed for the treatment of malignant pleural mesothelioma (MPM). PATIENTS AND METHODS Patients with a histologically proven diagnosis of MPM, chemotherapy-naive measurable lesions, and adequate organ function received pemetrexed (500 mg/m2) intravenously over 10 minutes every 3 weeks. After a protocol change, most patients also received folic acid and vitamin B12 supplementation to improve safety. RESULTS A total of 64 patients were enrolled. Nine (14.1%) of the 64 patients had a partial response. The Kaplan-Meier estimate for median overall survival was 10.7 months. Forty-three patients received vitamin supplementation for all courses of therapy, and 21 patients did not. Seven of the nine responders were vitamin supplemented. The median overall survival was 13.0 months for supplemented patients and 8.0 months for nonsupplemented patients. Vitamin-supplemented patients completed more cycles of therapy than nonsupplemented patients (median, six v two cycles, respectively). Grade 3/4 neutropenia (23.4%) and grade 3/4 leukopenia (18.8%) were the most common laboratory toxicities. Fatigue and febrile neutropenia were the most commonly reported nonlaboratory events (grade 3, 6.3%; grade 4, 0.0% each). The incidence of these toxicities was generally lower in the supplemented patients. CONCLUSION Single-agent pemetrexed for MPM resulted in a moderate response rate (14.1%) and median overall survival of 10.7 months. Patients supplemented with folic acid and vitamin B12 tolerated treatment better (less toxicity and more cycles of treatment) and had a 5-month greater median overall survival than nonsupplemented patients. These results indicate that patients with MPM could benefit from single-agent pemetrexed treatment combined with vitamin supplementation.

Abstract
This study was performed to assess the feasibility of administering 1843U89, a potent, noncompetitive inhibitor of thymidylate synthase that does not require polyglutamation for activity, as a 2-min i.v. infusion daily for 5 days every 3 weeks, to determine whether folic acid supplementation ameliorates the toxic effects of 1843U89 and permits further dose escalation, and to recommend doses of 1843U89 administered without and with folic acid for further clinical evaluations. The study also sought to characterize the pharmacokinetic behavior of 1843U89 and to seek preliminary evidence of anticancer activity. Patients with advanced solid malignancies were treated with escalating doses of 1843U89 as a 2-min i.v. infusion daily for 5 days every 3 weeks. Initially, patients were treated in the absence of high-dose folic acid until dose-limiting toxicity was consistently noted. Next, patients were treated with escalating doses of 1843U89 preceded by 1000 mg of folic acid administered p.o. 30 min before each of the 5 daily doses of 1843U89. Patients (32) received 101 total courses of 1843U89 at doses ranging from 1 to 6 mg/m(2)/day with and without folic acid. At the 2 mg/m(2)/day dose level without folic acid, 2 of 7 new patients experienced dose-limiting toxicity, principally neutropenia, mucositis, and malaise in 3 of 11 courses. 1843U89 doses were further increased with folic acid to 6 mg/m(2)/day, but repetitive treatment was not feasible at this dose level because of an unacceptable high incidence of severe neutropenia and mucositis. Other toxicities included thrombocytopenia, rash, and fever. In contrast, repetitive treatment at the 5 mg/m(2)/day dose level was feasible. The pharmacokinetics of 1843U89 were neither dose dependent nor affected by folic acid. On day 1, clearance, terminal half-life, and steady-state volume of distribution values averaged 47.1 +/- 21.7 ml/min/m(2), 7.72 +/- 4.09 h, and 16.7 +/- 8.8 liter/m(2)/h, respectively. The results of the study indicate that the administration of 1843U89 as a 2-min infusion daily for 5 days every 3 weeks without and with folic acid is feasible at 1843U89 doses as high as 2 and 5 mg/m(2)/day, respectively. Because folic acid pretreatment results in no diminution of the antitumor activity of 1843U89 in preclinical studies and ameliorates the toxic effects of 1843U89 in both preclinical models and cancer patients, the therapeutic index of 1843U89 may be enhanced by folic acid pretreatment and, therefore, the development of 1843U89 with folic acid is warranted. However, the question of whether to administer 1843U89 at a dose of 2 mg/m(2)/day with folic acid, which is associated with negligible toxicity, or at its highest feasible dose with folic acid, 5 mg/m(2)/day, should be addressed in appropriately designed trials.

Abstract
PURPOSE To evaluate the safety and efficacy of a five-day regimen of oral 5-fluorouracil (5-FU) plus eniluracil (776C85) in patients with metastatic colorectal cancer (CRC). PATIENTS AND METHODS Seventy-five patients with metastatic CRC that was previously untreated or refractory to 5-FU-leucovorin (LV) were enrolled and divided into two strata based upon their treatment history. Twenty-four had not previously received chemotherapy or had received adjuvant chemotherapy that ended > 6 months prior to enrollment on study (previously untreated stratum). Fifty-one patients had disease refractory to intravenous (i.v.) 5-FU-LV (previously treated stratum). All patients received seven consecutive daily doses of eniluracil (20 mg/day) with once daily oral 5-FU given on days 2-6, repeated every four weeks. One-half of the patients in each stratum also received 50 mg/day oral LV on days 2-6. The 5-FU dose was 25 mg/m2 when administered without LV and 20 mg/m2 when administered with LV. RESULTS Partial response (PR) was noted in 2 of 12 patients receiving eniluracil-5-FU and in 3 of 12 patients receiving eniluracil-5-FU-LV in the previously untreated stratum. No responses were observed in the refractory disease stratum, however, 15 patients (30%) demonstrated stable disease over 2-18+ courses of therapy. Non-hematologic toxicities were mild; only 7% of patients experienced grade 3 diarrhea. Myelosuppression was frequent and dose limiting. Neutropenic sepsis was reported in 13.5% of patients. CONCLUSIONS Eniluracil with 5-FU administered orally with or without LV on a five-day schedule is active and well tolerated when given as primary therapy to patients with metastatic CRC.

Abstract
PURPOSE This study was undertaken to evaluate the feasibility of administering docetaxel (Taxotere; Rhône-Poulenc-Rorer) as a one-hour intravenous (i.v.) infusion on day 1 combined with 5-fluorouracil (5-FU) as a bolus i.v. injection for five (days 1-5) or three (days 1-3) consecutive days every four weeks. PATIENTS AND METHODS Thirty-seven patients with advanced solid malignancies were treated with 115 total courses involving seven dose levels of the two regimens of docetaxel and 5-FU (docetaxel/5-FU [mg/m2]/mg/m2/d]). In an effort to reduce fluid retention and hypersensitivity phenomena related to docetaxel, patients received premedication with dexamethasone 8 mg orally twice daily for three consecutive days beginning 24 hours before treatment. RESULTS Severe (grade 4) neutropenia lasting longer than seven days with or without fever and/or severe mucositis, precluded further dose escalation above docetaxel 60 mg/m2 on day 1 and 5-FU 300 mg/m2/day administered on days 1-5 every four weeks. The rates of these toxic effects were also unacceptably high above docetaxel 60 mg/m2 on day 1 and 5-FU 300 mg/m2/day administered on days 1-3 every four weeks. Nine patients experienced various manifestations of fluid-retention that were potentially related to study drugs. However, neither treatment delay nor discontinuation of treatment was required. Nausea, vomiting, diarrhea, and fatigue, were mild to modest in severity and occurred infrequently (< 10% of courses). Two patients with metastatic breast cancer experienced complete responses and a partial response occurred in a patient with metastatic non-small-cell lung cancer. CONCLUSION Based on the results of this study, the regimen of docetaxel 60 mg/m2 on day 1 followed by 5-FU 300 mg/m2/d i.v. for three or five days every four weeks is well tolerated and these doses are recommended for further evaluations. The feasibility of administering docetaxel 60 mg/m2 followed by 5-FU 300 mg/m2 for three or five days every four weeks and the preliminary antitumor activity noted indicate that further disease-directed studies of docetaxel and 5-FU are warranted in patients with relevant solid malignancies.

Abstract
Prolonged exposure to topotecan in in vitro and in vivo experiments has yielded the highest antitumor efficacy. An oral formulation of topotecan with a bioavailability of 32-44% in humans enables convenient prolonged administration. Pharmacokinetic/pharmacodynamic relationships from four Phase I studies with different schedules of administration of oral topotecan in 99 adult patients with malignant solid tumors refractory to standard forms of chemotherapy were compared. Topotecan was administered as follows: (a) once daily (o.d.) for 5 days every 21 days (29 patients); (b) o.d. for 10 days every 21 days (19 patients); (c) twice daily (b.i.d.) for 10 days every 21 days (20 patients); and (d) b.i.d. for 21 days every 28 days (31 patients). Pharmacokinetic analysis was performed in 55 patients using a validated high-performance liquid chromatographic assay and noncompartmental pharmacokinetic methods. Totals of 109, 48, 64, and 59 courses were given, respectively. Dose-limiting toxicity consisted of granulocytopenia for the o.d. x 5-day dosage, a combination of myelosuppression and diarrhea in both of the 10-day schedules, and only diarrhea in the 21-day schedule. Pharmacokinetics revealed a substantial variation of the area under curve (AUC) of topotecan lactone in all of the dose schedules with a mean intrapatient variation of 25.4 +/- 31.0% (o.d. x 5), 34.5 +/- 25.0% (o.d. x 10), 96.5 +/- 70.1% (b.i.d. x 10), and 59.5 +/- 51.0% (b.i.d. x 21). Significant correlations were observed between myelotoxicity parameters and AUC(t) day 1 and AUC(t) per course of topotecan lactone. In all of the studies, similar sigmoidal relationships could be established between AUC(t) per course and the percentage decrease of WBCs. At maximum-tolerated dose level, no significant difference in AUC(t) per course was found [AUC(t) per course was 107.4 +/- 33.7 ng x h/ml (o.d. x 5), 145.3 +/- 23.8 ng x h/ml (o.d. x 10), 100.0 +/- 41.5 ng x h/ml (b.i.d. x 10), and 164.9 +/- 92.2 ng x h/ml (b.i.d. x 21), respectively.] For oral topotecan, the schedule rather than the AUC(t)-per-course seemed to be related to the type of toxicity. Prolonged oral administration resulted in intestinal side effects as a dose-limiting toxicity, and short-term administration resulted in granulocytopenia. On the basis of this pharmacokinetic study, no schedule preference could be expressed, but based on patient convenience, administration once daily for 5 days could be favored.

Abstract
The weekly administration of docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) at doses up to and including 40 mg/m2 induces low levels of hematologic and nonhematologic toxicity. In particular, weekly scheduling appears to markedly reduce the incidence of neutropenia compared with regimens in which an equivalent dose rate (mg/m2/wk) is given once every 3 weeks. Encouraging responses have been reported in patients with a range of tumor types, including breast cancer, treated with weekly docetaxel. Further trials of weekly docetaxel are in progress, and it appears that this schedule may prove particularly valuable in certain elderly patients who are unsuited to more aggressive chemotherapy.

Abstract
Topotecan is a specific inhibitor to topoisomerase I. An oral formulation of topotecan is available with a bioavailability of 32-44% in humans. A phase I and pharmacological study of the oral formulation of topotecan administered daily for 5 days every 21 days was performed in adult patients with solid tumours to determine the maximum tolerated dose (MTD). Adult patients with a WHO performance status < or = 2 adequate haematological, hepatic and renal functions, with malignant solid tumours refractory to standard forms were entered into the study. Pharmacokinetics were performed on days 1 and 4 of the first course using a validated high performance liquid chromatographic assay. 29 patients entered the study, all patients were evaluable for toxicity and response. The doses studied in the 29 patients were 1.2, 1.8, 2.3, 2.7 mg/m2/day and a fixed dose of 4 mg/day without surface area adjustment. A total of 109 courses were given. Dose limiting toxicity (DLT) was reached at a dose of 2.7 mg/m2/day and consisted of CTC (NCI-Common Toxicity Criteria) grade IV granulocytopenia. The regimen was well tolerated. Non-haematological toxicities were mild, including fatigue, anorexia, nausea, vomiting and diarrhoea. A significant correlation was observed between the percentage decrease in white blood cells versus the area under the curve (AUC(t)) of topotecan lactone (R = 0.76 P < 0.01) which was modelled by a sigmoidal Emax function. The correlation coefficient between the absolute topotecan dose administered and the AUC(t) was R = 0.52 (P = 0.04). Pharmacokinetics of the fixed dose of 4 mg/day were comparable to the 2.3 mg/m2/day dose. DLT in this phase I study of five daily doses of oral topotecan every 21 days was granulocytopenia. The recommended dose for phase II studies is 2.3 mg/m2/day or alternatively, a fixed dose of 4 mg/day.

Abstract
Prolonged exposure to topotecan (TPT) in in vitro experiments and in vivo studies in animals yielded the highest antitumor efficacy. An oral bioavailability of TPT of 32-44% enables convenient prolonged administration. Because of unpredictable diarrhea in the third week of the twice daily (b.i.d.) 21-day schedule of p.o. administered TPT and the finding of optimal down-regulation of topoisomerase I level after 10-14 days in mononuclear peripheral blood cells, a shorter period of administration (10 days) was chosen for Phase I and pharmacological studies of oral administration of TPT. Adult patients with malignant solid tumors that were refractory to standard forms of chemotherapy were entered. Two dose schedules were studied: once daily (o.d.) and b.i.d. administration for 10 days every 3 weeks. TPT o.d. for 10 days was studied at dose levels 1.0, 1.4, and 1.6 mg/m2/day, and dose levels were 0.5, 0.6, 0.7, and 0.8 mg/m2 with the 10-day b.i.d. schedule. Pharmacokinetics were performed on days 1 and 8 of the first course using a validated high-performance liquid chromatographic assay and noncompartmental pharmacokinetic methods. Nineteen patients were entered in the 10-day o.d. schedule, with a total of 48 courses given. Dose-limiting toxicity (DLT) was reached at 1.6 mg/m2/day and consisted of common toxicity criteria (CTC) grade IV thrombocytopenia and CTC grade III diarrhea. The maximum tolerated dose was 1.4 mg/m2/day. In the 10-day b.i.d. administration of TPT, a total of 64 courses were studied in 20 patients. DLT was reached at a dose of 0.8 mg/m2 b.i.d. and consisted of CTC grade IV myelosuppression and CTC grade IV diarrhea. The maximum tolerated dose was 0.7 mg/m2 b.i.d. Nonhematological toxicities with both schedules included mild nausea and vomiting, fatigue, and anorexia. Pharmacokinetics revealed a substantial variation of the area under the plasma concentration-time curve of TPT lactone in both schedules. Significant correlations were observed between the myelotoxicity parameters and the area under the plasma concentration-time curve at day 1 of TPT lactone o.d. and b.i.d. The DLT of 10 daily administrations of oral topotecan every 3 weeks consisted of a combination of myelosuppression and diarrhea for both schedules studied. The recommended doses for Phase II studies are 1.4 mg/m2/day for 10 days for the o.d. administration and 0.7 mg/m2 for the b.i.d. schedule.

Abstract
BACKGROUND Human corticotropin-releasing factor (hCRF) is an endogenous peptide responsible for the secretion and synthesis of corticosteroids. In animal models of peritumoral brain edema, hCRF has significant anti-edematous action. This effect, which appears to be independent of the release of adrenal steroids, appears mediated by a direct effect on endothelial cells. We conducted a feasibility and phase I study with hCRF given by continuous infusion to patients with brain metastasis. PATIENTS AND METHODS Peritumoral brain edema documented by MRI and the use of either no steroids or stable steroid doses for more than a week were required. MRIs were repeated at completion of infusion and estimations by dual echo-image sequence (Proton density and T2-weighted images) of the amount of peritumoral edema were performed. The study was performed in two stages. In the feasibility part, patients were randomized to receive either 0.66 or 1 microgram/kg/h of hCRF or placebo over 24 hours. The second part was a dose finding study of hCRF over 72 hours at escalating doses. RESULTS Seventeen patients were enrolled; only one was receiving steroids (stable doses) at study entrance; dose-limiting toxicity (hypotension) was observed at 4 micrograms/kg/h x 72 hours in two out of four patients, while zero of five patients treated at 2 micrograms/kg/h developed dose-limiting toxicities. Flushing and hot flashes were also observed. Improvement of neurological symptoms and/or exam were seen in 10 patients. Only small changes were detected by MRI. Improvement in symptoms did not correlate with changes in cortisol levels, and changes in cortisol levels were not correlated with changes in peritumoral edema. CONCLUSIONS hCRF is well tolerated in doses up to 2 micrograms/kg/h by continuous infusion x 72 hours. Hypotension limits administration of higher doses. The observation of clinical benefit in the absence of corticosteroids suggests hCRF may be an alternative to steroids for the treatment of patients with peritumoral brain edema. Further exploration of this agent in efficacy studies is warranted.

Abstract
The relatively recent introduction of a new class of chemotherapeutic agents--the taxoids--has raised hope of improved survival for patients with advanced or metastatic cancer. Following encouraging preclinical results of taxoid combinations, this phase I, nonrandomized trial was designed to evaluate a 1-hour intravenous infusion of docetaxel (Taxotere) on day 1 combined with fluorouracil (5-FU) as a daily intravenous bolus for 5 consecutive days. To date, 27 patients with advanced solid neoplasms have received 86 courses of docetaxel/5-FU at the following dose levels: 25/100, 35/150, 50/200, 60/200, and 60/300 mg/m2. Preliminary results showed no unexpected toxicities, and the principal toxicity was neutropenia of short duration. A treatment regimen of 60 mg/m2 docetaxel on day 1 and 300 mg/m2 of 5-FU given for 5 days, with a single course length of 28 days, is projected as the maximum tolerated dose.

Abstract
An early study with gemcitabine in pancreas cancer indicated greater relief of disease-related symptoms than expected from the objective tumour response rate. A novel design was created to assess changes in symptomatology prospectively in two studies. The design focuses on typical features seen in patients with advanced pancreas cancer (pain, impaired function, weight loss) and the endpoint is 'clinical benefit response'. Traditional endpoints of objective tumour response and survival were also included. In a randomised study, the clinical benefit response rate for gemcitabine was 24% compared with 5% for 5-fluorouracil (5-FU) (P = 0.0022). The median survival was 5.65 months for gemcitabine compared with 4.41 months for 5-FU (P = 0.0025). The corresponding objective response rates were 5.4% and 0%. Disease stabilised in 39% and 19% of gemcitabine and 5-FU patients, respectively. In a second study of 5-FU-refractory patients, 27.0% of patients were clinical benefit responders. The median survival in this second study was 3.8 months; the objective response rate was 11%, and 30% of patients had stable disease. These trials show that gemcitabine improves disease-related symptoms and survival in patients with pancreas cancer.

Abstract
PURPOSE To compare the efficacy and safety of oral granisetron hydrochloride tablets with that of oral prochlorperazine sustained-release capsules in preventing nausea and emesis induced by moderately emetogenic chemotherapeutic agents. PATIENTS AND METHODS In this multicenter, double-blind, randomized, parallel group study, oral granisetron and oral prochlorperazine were compared in 230 chemotherapy-naive, adult cancer patients who received moderately emetogenic chemotherapy. Patients were stratified by gender and randomized to receive either 1.0 mg oral granisetron HCI twice a day for 7 days, or 10 mg oral prochlorperazine sustained-release capsules twice a day for 7 days. The first dose was given 1 hour before initiation of chemotherapy and the second dose 12 hours after the first dose. Patients were evaluated for emetic episodes, extent of nausea, and adverse events for 7 days after the start of chemotherapy. Primary efficacy parameters were complete response (no emetic episodes, no greater than mild nausea, no antiemetic rescue) and total control (no emetic episodes, no nausea, no antiemetic rescue) in the 24 hours after the start of chemotherapy. RESULTS Granisetron was significantly more effective than prochlorperazine in achieving a complete response (74% vs. 41%, respectively) and total control of nausea and vomiting (58% vs. 33%, respectively) at the 24-hour assessment. Complete response at 24 hours was significantly higher in the granisetron-treated patients than in prochlorperazine-treated patients. In women, granisetron showed a complete response rate of 69% versus 38% with prochlorperazine; in men, granisetron showed a complete response rate of 92% versus 61% with prochlorperazine. Both regimens were well tolerated, with headache (36% for granisetron, 29% for prochlorperazine) and constipation (31% for granisetron, 6% for prochlorperazine) the most common adverse events. CONCLUSIONS : Oral granisetron 1 mg twice a day was significantly more effective than oral prochlorperazine sustained release capsules 10 mg twice a day in complete response and total control of nausea and vomiting at 24 hours after chemotherapy. Both agents were well tolerated.

Abstract
BACKGROUND Anti-metabolites such as methotrexate (MTX) and 5-fluorouracil (5-FU) have been used clinically for many years. Although their effects are partly due to thymidylate synthase (TS) inhibition, they also have non-specific, non TS effects on RNA and purine synthesis. Direct and specific TS inhibitors therefore presented an attractive research target. Collaborative research between the Institute of Cancer Research and Zeneca Pharmaceuticals led to the design of specific folate based quinazoline TS inhibitors. ZD1694 ('Tomudex'), the first of these drugs reaching advanced clinical development, is currently completing phase III studies. DESIGN Eight phase II trials were carried out using 'Tomudex', 3.0 mg/m2, given as a short 15-minute infusion 3-weekly. RESULTS 'Tomudex' demonstrates activity in a range of tumour types, most notably advanced colorectal and breast cancer (objective response rate 26%) and has acceptable toxicity: the most common WHO grade 3 and 4 adverse events were self-limiting reversible increases in liver transaminases, transient leucopenia, diarrhoea, nausea and vomiting and tiredness or malaise. Mucositis/stomatitis, alopecia and skin toxicity were notable for their low incidence and mild intensity. CONCLUSIONS 'Tomudex' represents the successful culmination of a rational drug design programme, and shows promise as a new cytotoxic for the treatment of colorectal cancer. Further studies in other tumour types are planned.

Abstract
Docetaxel (Taxotere), a semisynthetic analogue of the antitumor agent paclitaxel, inhibits tubulin depolymerization. Paclitaxel produces a peripheral neuropathy. This study delineates clinically and electrophysiologically the characteristics of a peripheral neuropathy due to docetaxel. In 186 patients receiving docetaxel in phase I and phase II protocols, we performed serial neurologic exams. As patients became symptomatic, quantitative sensory testing and nerve conduction studies were done. Twenty-one patients developed mild to moderate sensory neuropathy on taxotere at a wide range of cumulative doses (50 to 750 mg/m2) and dose levels (10 to 115 mg/m2). Ten of these patients also developed weakness of varying degree in proximal and distal extremities. Nine of the 21 patients had received neurotoxic chemotherapy before; 16 were treated with docetaxel at a dose level of 100 to 115 mg/m2. In summary, docetaxel produced a sensorimotor peripheral neuropathy in 11% of our patient population.

Abstract
PURPOSE To determine the potential efficacy and dose-limiting toxicity of taxotere, a hemisynthetic inhibitor of tubulin depolymerization. PATIENTS AND METHODS Fifty-eight patients were administered taxotere in this phase I clinical trial as a 6-hour or a 2-hour infusion repeated every 21 days. Forty patients received 181 courses on the 6-hour infusion schedule, and 18 patients received 105 courses on the 2-hour infusion schedule. RESULTS Neutropenia was the dose-limiting toxicity on both schedules. The maximally tolerated dose was 100 mg/m2 on the 6-hour infusion schedule and 115 mg/m2 on the 2-hour infusion schedule. The most prominent nonhematologic toxicities included mucositis (more prominent on the 6-hour infusion schedule), transient rash (more common on the 2-hour infusion schedule), and alopecia. Hypersensitivity reactions were seen in five patients. There was no evidence of neurotoxicity or cardiotoxicity. One partial response was noted on the 6-hour infusion schedule (one in refractory breast cancer) and four additional partial responses were noted on the 2-hour infusion schedule (two in adenocarcinoma of the lung, one in refractory breast cancer, one in cholangio-carcinoma). In addition, 10 patients had minor responses. Pharmacokinetic studies showed plasma concentrations of taxotere declined in a triexponential manner, with a terminal half-life of 11.8 hours. CONCLUSION The recommended starting dose for phase II taxotere trials is 100 mg/m2 administered as a 2-hour infusion, repeated every 21 days. Taxotere is a promising antineoplastic agent worthy of extensive phase II testing in patients with a variety of malignancies.

Abstract
Amplification of oncogenes in human tumors has been associated with a poor prognosis. Microscopically visible amplified oncogenes can be located either within chromosomes in homogeneously staining regions, or in an extrachromosomal compartment in double minutes (DMs). The DMs are composed of submicroscopic circular DNA (episomes), which have multimerized to form the microscopically visible DMs. When amplified oncogenes are located in an extrachromosomal location, they are vulnerable to loss from the cell. In this study we have found that the topoisomerase II inhibitor etoposide, in concentrations easily achievable clinically, causes a significant decrease in the number of DM-containing amplified oncogenes in three different human tumor cell lines. The elimination of amplified oncogenes from the cell could be accompanied by less aggressive tumor behavior.
