A 12-month oral repeated dose toxicity study of (+/-)-4-diethylamino-1, 1-dimethylbut-2-yn-1-yl 2-cyclohexyl-2-hydroxy-2-phenylacetate monohydrochloride monohydrate (NS-21), a new drug for the treatment of urinary frequency and incontinence, was conducted in beagle dogs. Male and female dogs were given the drug orally for 12 months at doses of 0 (control), 3, 17.5 and 100 mg/kg. After discontinuation of the treatment, a 2-month recovery test was also conducted. No effects related to the treatment were observed on survival and water consumption. Mydriasis, vomiting and a decrease in body weight or a suppression of its weight gain were seen in the 17.5 and 100 mg/kg groups. Salivation and a decrease in food consumption were seen in the 100 mg/kg group. Ophthalmologic examination confirmed the mydriasis in the 17.5 and 100 mg/kg groups. Electrocardiographic and hematological examinations and urinalysis showed no abnormalities attributable to the treatment. Blood chemical examination revealed increases in GPT and ALP in the 17.5 and 100 mg/kg groups, increases in GOT and triglyceride and a decrease in total protein in the 100 mg/kg group. Pathological examination disclosed hepatocellular hypertrophy and concentric lamellar bodies derived from the smooth-ER in the 100 mg/kg group, and hyperplasia of smooth-ER, an increase in number of lysosomes and bile pigments in the bile capillary, hepatocyte and stellate cells of Kupffer in the 17.5 and 100 mg/kg groups. The recovery test showed that the above-mentioned changes were satisfactorily reversible or the degree and frequency of these changes were lowered. The serum concentrations of NS-21 and its active metabolite. RCC-36, in the treated groups were increased in a dose-dependent manner. No treatment-related effects were seen in the 3 mg/kg group. These results show that the NOAEL (no observed adverse effect level) of NS-21 is 3 mg/kg for 12-month oral toxicity in dogs.

The inhibitory effects of GG032X tablets, a new dosage form (fast dispersing tablet) of ondansetron, 5-HT2 receptor antagonist, on nausea and emesis induced by cisplatin (CDDP), were investigated along with safety and usefulness. Subjects were chemotherapy patients starting CDDP administration for the first time, who were receiving a high single dose of CDDP (50 mg/m2 or more and intravenous drip infusion of less than 4 hours), or lower multiple doses of CDDP (a single dose of 10 mg/m2 or more, administered intravenously for 3-5 consecutive days). GG032X tablets were administered orally 1-2 hours before CDDP administration. In lower multiple doses of CDDP, GG032X tablets and CDDP were administered, as much as possible, at the same respective time when they were administered on the first day. Efficacy of GG032X tablets was evaluated in terms of inhibitory effect on nausea and emesis 24 hours after administration of a high single dose of CDDP, and of the inhibitory effect on nausea and emesis during the study period (3-5 days) in lower multiple doses of CDDP. Efficacy, safety and usefulness were evaluated in accordance with the evaluation criteria used in the clinical study of already-approved ondanstron tablets. In a high single dose of CDDP, the cases judged "effective" or better in the investigation of the inhibitory effect of the drug on nausea and emesis, accounted for 52.9% (63/119 cases). As for the overall safety rating, the cases judged as "safe" accounted for 87.0% (107/123 cases), and as a "minor safety problem" accounted for 13.0% (16/123 cases). As for the usefulness rating, the cases judged "useful" or better accounted for 52.1% (62/119 cases). Major adverse effects included headache, fever, atrial fibrillation and increases in total bilirubin, GOT and GPT values. None of these was serious, and the patients recovered without any treatment or by nosotropic therapy. Meanwhile, in lower multiple doses of CDDP, the inhibitory effect judged "effective" or better accounted for 70.6% (12/17 cases). As for the overall safety rating, all cases were judged "safe". In terms of usefulness, those cases judged "useful" or better accounted for 70.6% (12/17 cases). No adverse effect was observed. Study results of these two groups were almost the same as those for already-approved ondansetron tablets. According to the results of questionnaires for the patients who participated in the study and took GG032X tablets, the drug was found to be easy to take and had favorable results. Based on the above results, GG032X tablets were evaluated as having the same inhibitory effect as the already-approved ondansetron tablets against CDDP-induced nausea and emesis, and were considered safe and clinically useful.

To evaluate the feasibility of adjuvant chemotherapy, we analyzed the toxicities of chemotherapy for primary breast cancer in Japanese women. Since the opening of the National Cancer Center Hospital East, 180 female breast cancer patients have received adjuvant chemotherapy or chemo-hormonal therapy following surgical treatment between June 1992 and December 1995. On the basis of informed consent about prognosis and adjuvant therapy, most patients decided to choose the type of cytotoxic chemotherapy themselves. Adjuvant chemotherapy consisted of oral fluoropyrimidine compounds (OFP), cyclophosphamide + adriamycin +/- 5-fluorouracil [CA(F)] or cyclophosphamide + methotrexate + 5-fluorouracil (CMF). Toxicity was determined using the Toxicity Grading Criteria of the Japan Clinical Oncology Group (JCOG). Sixty-six patients received OFP, 59 CA(F) and the rest 55 CMF. The toxicity grading of leukocytes and neutrophils was significantly higher in patients treated with CA(F) or CMF than in those treated with OFP. Similar results were also seen relating to the toxicity of nausea/vomiting and alopecia. There was no statistical difference in the toxicity grading of hemoglobin, glutamic oxaloacetic transaminase/glutamic pyruvic transaminase (GOT/GPT) and stomatitis/ gastritis between the three groups of patients. Interestingly, the number of patients that were forced to discontinue chemotherapy was higher in those receiving OFP than in those receiving CA(F) or CMF. Cytotoxic chemotherapy of CA(F) or CMF results in greater toxicity than OFP, but is tolerated and feasible in the adjuvant setting used in Japanese breast cancer patients from the viewpoint of toxicities by anticancer chemotherapy.

Taltirelin tetrahydrate (TA-0910), novel thyrotropin-releasing hormone (TRH) analogue, was orally administered to dogs as dose levels 0.5, 5, and 50 mg/kg for 13 weeks and 0.15, 1.5 and 15 mg/kg for 52 weeks. Blood concentrations of test substance measured in 52-week study revealed that absorption of TA-0910 was with dose-dependent manner and not changed through the treatment period. These toxicokinetics suggested that there were no alterations on metabolism of TA-0910 with repeated treatment. The animals receiving 5 or 50 mg/kg showed decrease in body weight or suppression of body weight gain, and decrease in food intake (13-week study). As an abnormality in general conditions, vomiting and salivation (5 mg/kg or more, both in 13- and 52-week studies), increase in behavior as water intake (5 mg/kg or more, 13-week study), and hyperlocomotion (50 mg/kg) were observed. Elevating GPT values were noted temporally in the animals treated with 5 mg/kg or more (both in 13- and 52-week studies) without abnormal findings in histopathology. The thyroid weights were increased in treated animals receiving 5 or 50 mg/kg in 13-week study, but no histopathological changes were noted. Electron microscopy revealed dilatation of granular endoplasmic reticulums in follicular cells of thyroid from 50 mg/kg group in 13-week study. It was concluded that no-effect levels of 13- and 52-week studies were 0.5 mg/kg and 1.5 mg/kg, respectively.

Azithromycin (AZM), a new oral macrolide antibiotic, in 10% fine granules or 100 mg capsules was given to pediatric patients to treat various infections. The following results were obtained in our studies of AZM for its antibacterial activities against clinical isolates, its pharmacokinetics, its efficacy, and its safety. 1. MICs of AZM, erythromycin (EM) and clarithromycin (CAM) were determined against a total of 57 strains all at 10(6) cfu/ml. Among Gram-positive cocci, MICs of AZM ranged from 0.78 to > 100 micrograms/ml against Staphylococcus aureus (20 strains), from 0.05 to 0.1 microgram/ml against Streptococcus pyogenes (11 strains), and from 0.0125 to 3.13 micrograms/ml against Streptococcus pneumoniae (10 strains). These MICs were similar to those of the other macrolides. Among Gram-negative bacilli, MICs of AZM were 0.05 micrograms/ml against Moraxella subgenus Branhamella catarrhalis (1 strain), from 0.78 to 3.13 micrograms/ml against Haemophilus influenzae (9 strains), 0.78 micrograms/ml against Haemophilus parainfluenzae (1 strain) and 6.25 micrograms/ml against salmonella sp. (1 strain). These values were similar to or lower than those of the other macrolides. Against Mycoplasma pneumoniae, MICs of AZM were < or = 0.0008 micrograms/ml in three strains. One strain of M. pneumoniae showed tolerance to AZM at MIC 25 micrograms/ml. The other agents exhibited higher MIC than AZM against this organism. 2. Plasma samples were collected from five patients receiving fine granules and four patients receiving capsules for drug level determination. The patients received AZM at 10.0 approximately 16.3 mg/kg body weight once daily for 3 days. Drug concentrations in plasma at two hours after Day 3 dosing were in a range between 0.02 and 0.19 micrograms/ml for fine granules and were in a range between 0.11 and 0.42 micrograms/ml for capsules. 3. Urine samples were collected from four patients receiving fine granules and four patients receiving capsules. Drug levels were determined to be 3 micrograms/ml at post-treatment 48 hours for fine granules and post-treatment 72 hours for capsules. Urinary excretion rates of AZM in three patients on capsules lied in a range between 4.69 and 10.17%. 4. Effectiveness of AZM in fine granules was evaluated in 128 patients having a total of 19 different infections. AZM was rated "excellent" in 51 patients, "good" in 63, "fair" in 8, "poor" in 6, resulting in an efficacy rate of 89.1%. Effectiveness of AZM in capsular form was evaluated in 23 patients with five different infections. AZM was found "excellent" in 13 patients and "good" in 10, resulting in an efficacy rate of 100%. 5. AZM in fine granules eradicated 45 strains of 54 in 8 different bacteria. AZM in capsules eradicated 9 strains of 10 strains in 6 different bacteria. 6. As for adverse reactions, one patient complained of eruption, one vomiting, one loose stool, five diarrhea, when administered with fine granular form of AZM. One patient on AZM capsules experienced urticaria and vomiting. 7. As for abnormal laboratory changes, three patients were found with decreased WBC, seven with increased eosinophil, two with increased GOT and GPT, one with increased GPT. They were all on fine granular form of AZM. As far as abnormalities found in patients administered with AZM in capsular form, two showed decreased WBC, one decreased WBC along with increased eosinophil, and three increased eosinophil.

A multicenter cooperative phase I study of ZD-1694 (raltitrexed), a novel, folate-based thymidylate synthase (TS) inhibitor, was conducted with single and repeated doses in 30 patients with various malignant tumors. ZD-1694 was intravenously infused over 15 minutes. In the single-dose study, the initial dose was fixed at 1.0 mg/m2 (1n), and the dose was escalated stepwise up to 3.5 mg/m2 (3.5 n). Based on the results of the single-dose study, in the repeated-dose study, doses of 2.5 n and 3 n were infused every three weeks (3 weeks/one course). In principle, patients received 2 courses or more. Of the 29 eligible patients, 16 were in the single-dose study and 13 in the repeated-dose study. Adverse reactions were evaluated in all eligible patients. In the single-dose study, neutropenia, nausea/vomiting, diarrhea, and transaminase (GOT, GPT) increases, of grade 3 or higher, occurred at high doses of 3 n and 3.5 n. These were regarded as dose-limiting toxicities (DLT). DLT of grade 3 or higher were observed in 1 of 4 patients given 3 n and 2 of 4 patients given 3.5 n. These results suggested that the maximum tolerated dose (MTD) of ZD-1694 was 3.5 n (3.5 mg/m2). In the repeated-dose study, DLT of grade 3 or higher was observed in no more than one third of each dose group, 2 of the 6 patients given 2.5 n and 2 of the 7 patients given 3 n. These results suggested that 3 n (3.0 mg/m2), a dose nearer to MTD, was the recommended dose for the phase II study. Although transaminase increases were observed in all patients, in 12 of them the increase was grade 2 or lower and reversible. A pharmacokinetic investigation showed the mean elimination half life of ZD-1694 plasma concentration was 91.5 hours in the single-dose group and 119.1 hours in the repeated dose group. It was suggested that ZD-1694 is metabolized to polyglutamates after uptake and retained in the cells for a long duration. However, no accumulation was seen in plasma concentration of ZD-1694 following repeated doses at 3-weekly intervals. One PR was observed in a patient with colorectal cancer receiving 2.5 n in the repeated-dose study. Based on these results, the recommended dosage and administration for the phase II study of ZD-1694 was 3 n (3.0 mg/m2) intravenously infused over 15 minutes every 3 weeks.

Docetaxel has been reported to show promising anti-tumour activity in pancreatic ductal cancer (PC). This study was conducted to evaluate the activity and toxicity of moderate-dose (60 mg m(-2)) docetaxel in Japanese chemo-naive patients with measurable metastatic PC. The patients had a performance status of 0-2. They received docetaxel intravenously over a 1- to 2-h period without any premedication for hypersensitivity reactions. This treatment was repeated every 3-4 weeks with dose adjustments based on the toxic effects observed. Twenty-one patients were eligible and treated with docetaxel. The median number of courses was 2 (range, 1-4). None of the patients achieved an objective response; seven showed no change and 13 showed progressive disease. In one patient, the response was not assessable because of early death. The median survival time for all patients was 118 days. The main grade 3-4 toxicities by patient were leucocytopenia (67%) and neutropenia (86%). Other grade 3-4 toxicities included anaemia (10%), thrombocytopenia (5%), nausea/vomiting (29%), anorexia (29%), GOT/GPT increase (10%), alkaline phosphatase increase (14%), malaise/fatigue (33%) and alopecia (24%). In conclusion, docetaxel, administered on this schedule, did not show significant anti-tumour activity in patients with metastatic PC.

Gadobenate dimeglumine formulation (E7155), at doses of 0 (physiological saline), 0.25, 0.5, 1 and 2 mmol/kg/day of body weight, was administered intravenously to male and female beagle dogs once daily for 4 consecutive weeks in order to evaluate the subacute toxicity of the test article. Reversibility of toxicity was evaluated during a 4-week recovery period at 1 and 2 mmol/kg/day. No toxicologically significant changes were observed at 0.25 and 0.5 mmol/kg/day. In animals receiving 1 or 2 mmol/kg/day, transient swelling and redness of the facial and eye areas, lethargy, decreased activity, emesis, retching, watery or unformed stool, decreased body weight or body weight gain, decreased food consumption, decreased hematocrit and hemoglobin concentration, increased APTT, increases in plasma ALP, GPT or gamma-GT, decreased plasma inorganic phosphorus, total protein or albumin, increased liver or kidney weight, subacute inflammatory infiltrates, loss of centrilobular hepatocytes or hepatocellular cytoplamic vacuolation in the liver, vacuoles in the epithelial cells of the renal tubles and/or hypocellularity in the bone marrow were seen. The results of toxicokinetic analysis showed that systemic exposure was similar in males and females, and there was no accumulation of the test material over the treatment period, although AUC tended to be enhanced by slightly more than the proportionate dose increase. These effects were recovered or tended to be reversed after a post-dosing period for 4 weeks. In conclusion, the No Observed Adverse Effect Level (NOAEL) was 0.5 mmol/kg/day.

Based on the results of our previous pilot study, we conducted a multi-institutional phase II study of combination chemotherapy consisting of oral UFT (Taiho Pharmaceutical Co. Ltd, Tokyo) plus cisplatin (CDDP) in patients with advanced non-small cell lung cancer (NSCLC). UFT capsule containing 100 mg tegafur and 224 mg uracil was orally administered in two divided doses on days 1 through 21 making the total tegafur dose 400 mg/m(2)/day (maximum 600 mg/body). CDDP was administered by drip infusion at a dose of 20 mg/m(2) on a 5-day schedule from day 8 to 12. Treatment was repeated every 4 weeks as long as the criteria for initiation of therapy were still met. Between April 1995 and March 1997, 51 patients were entered into the study. The mean age of all 50 eligible patients was 64 years(range: 40-78). There were 21 patients with clinical stage IIIB disease and 29 patients with IV disease. Thirty-two patients had adenocarcinoma, 14 had epidermoid carcinoma, and four had large cell carcinoma. Of the 47 assessable patients, 18 achieved a partial response with an overall response rate of 38.3% (95% confidence interval: 24.4-52.2%). The median response duration was 113 days. The median survival time of the eligible patients was 12.8 months, and the 1-year survival rate was 54%. Among the 51 patients enrolled, grade 3 or 4 leukopenia developed in one patient (2%), neutropenia in six patients (11. 8%), thrombocytopenia in six patients (11. 8%), and anemia in three patients (5. 9%). Non-hematological grade 3 or 4 toxicities included anorexia in 10 patients (19.6%), nausea in ten (19.6%), vomiting in two (3.9%), and diarrhea in two (3. 9%). Grade 3 abnormal laboratory data included bilirubinemia in four (7. 8%), GPT elevation in one (2.0%), and hematuria in one (2.0%). In conclusion, combination of CDDP plus oral UFT is efficacious, with low toxicity, in the treatment of advanced NSCLC. In particular, the low hematological toxicity may warrant application of this regimen to the treatment of elderly patients and in trials of concurrent chemoradiotherapy in patients with locally advanced NSCLC.

An early phase II multi-center collaborative study of amrubicin hydrochloride, a novel synthetic anthracycline derivative anticancer agent, was conducted for malignant lymphoma at 12 institutions nationwide. A total of 41 patients were enrolled in this study between January 1988 and October 1990. Of these, 36 patients, six patients with Hodgkin's disease (HD) and 30 patients with non-Hodgkin's lymphoma (NHL), were eligible for the study. The starting dose of amrubicin hydrochloride was 100 mg/m2 (body surface area) and it was administered once every three weeks, in principle. The efficacy was assessed for 34 patients, excluding two patients: one who has not been followed up adequately and the other violated the dosing schedule (once per week). The overall response rates (CR + PR) were 50.0% (3/6) for HD and 42.9% (12/28) for NHL. Furthermore, a relatively high response rate was noted in 8 (36.4%) of 22 NHL patients who had been treated with other anthracycline derivatives prior to the trial. The safety of amrubicin hydrochloride was assessed for 36 eligible patients. Leukopenia (grade 3 or higher) and thrombocytopenia were noted in 21 patients (58.3%) and 10 patients (27.8%), respectively. Anorexia, nausea/vomiting, fever, alopecia, decrease in hemoglobin and elevations of GOT and GPT levels were observed with a relatively high frequency. Other than myelosuppression, the following adverse reactions (grade 3 or higher) occurred during the course of the trial: diarrhea (two patients), alopecia (two patients), stomatitis (one patient), anorexia (one patient), nausea/vomiting (one patient) and fever (one patient). In conclusion, these results indicate that amrubicin hydrochloride is effective in the treatment of patients with malignant lymphoma.
