From October, 1993 to September, 1994 a controlled clinical trial was conducted in 60 patients on Furlutal in the prevention of anorexia, weight loss and myelosuppression caused by chemotherapy. Patients were randomly divieded into three groups, they received Furlutal in the 1st (group A), 2nd (group B) and every cycle in (group C), respectively. The results show that Furlutal is effective in preventing anorexia, weight loss and myelosuppression. In group A, 85% patients gained weight, averaged 2.5kg (range: 1-7kg); 80% in group B, averged 2.25kg (1-7kg) and 95% in group C, averaged 4kg (2.5-8kg). Grade III myelosuppression, according to WHO criteria, 52.5% occurred in of patients treated with 80 cycles of chemotherapy only while it occurred in 19% in those treated with 100 cycles of chemotherapy plus Furlutal (P < 0.01).

We report a case of lung metastasis from bladder cancer effectively responding to a combination chemotherapy using methotrexate, epirubicin and cisplatin (MEC therapy). A 78-year-old man with high grade bladder cancer underwent total cystectomy on June 5, 1991. He was pointed out to have an abnormal shadow on the plain chest X-ray on August 14, 1992. Computed tomography demonstrated multiple lung metastasis. MEC combination chemotherapy was applied for this case. After 3 courses of MEC therapy, computed tomography showed marked regression of tumor. He has been alive for 12 months with no evidence of disease after chemotherapy. Toxicity of MEC therapy were moderate myelosuppression and mild anorexia and alopecia. These toxicity was adequately tolerable by the 78-year-old patient. This case suggests that MEC therapy is effective against advanced bladder cancer.

Methoxymorpholinyldoxorubicin (FCE 23762) is a novel, highly lipophilic doxorubicin analogue. It possesses potent in vitro and in vivo antitumor activity including efficacy in multidrug-resistant tumor cell lines. It is also metabolically activated in vivo resulting in an 80-fold increase in potency over the parent drug. In this phase I study the drug was administered by i.v. bolus injection at 3-week intervals. Fifty-three patients with refractory solid tumors were treated; 133 courses of FCE 23762 were administered at doses ranging from 30 to 2250 micrograms/m2. The dose limiting toxicity was reversible myelo-suppression (granulocytopenia and thrombocytopenia), demonstrating a delayed nadir and recovery in comparison to doxorubicin. Other toxicities included transient elevation of hepatic transaminases, delayed and prolonged nausea and vomiting, mucositis, anorexia, fatigue, and diarrhea. Heavily pretreated patients demonstrated more myelosuppression than previously untreated patients at 1250 micrograms/m2. No cardiotoxicity was observed. Four objective tumor responses were seen: one complete response in a patient with pelvic recurrence of cervical cancer; one partial response in a patient with cutaneous and lymph gland metastases from head and neck cancer; and two minor responses in patients with liver metastases from colorectal cancer. Plasma concentrations of FCE 23762 and its 13-dihydro metabolite, FCE 26176, were measured in 20 patients at doses > or = 675 micrograms/m2, using HPLC with fluorescence detection. The area under the plasma concentration-time curve ranged from 30 to 80 ng/h/ml; plasma data suggested linear kinetics in the range of tested doses (although there was considerable interpatient variability). The maximum tolerated dose defined in this study using this schedule is 1500 micrograms/m2. A safe phase II dose for previously untreated patients using this schedule is 1250 micrograms/m2; however, this may actually be below the optimal dose for this patient population.

A phase I study of NKT-01 (deoxyspergualin), which is a derivative of an antitumor antibiotic, spergualin, was performed by a cooperative study group. NKT-01 was given intravenously by 3-h infusion. The effect of single administration was studied prior to evaluation of daily administration for 5 consecutive days. In all, 5 and 33 patients with various malignancies, including leukemia, were entered into the trials of single and daily administration, respectively. In the single-administration study, all patients were evaluable and no clear adverse effect was observed at doses ranging from 20 to 320 mg/m2. In the daily-administration study, 28 evaluable patients (16 men and 12 women; median age, 55.5 years) were treated with a daily dose of 20-500 mg/m2. Toxicities such as myelosuppression, mild nausea/vomiting, anorexia, alopecia, tongue and perioral numbness, and hypotension were observed dose-dependently during or after the treatment. Grade 2 leukopenia, thrombocytopenia, and anemia were experienced at a dose of 500 mg/m2. These usually recovered to normal values by approximately 3 weeks after treatment. A pharmacokinetic analysis of single administration revealed rapid plasma clearance, with mean half-lives for the alpha and beta phases being 28 min and 6.9 h, respectively. Approximately 12% of the infused dose was excreted into the urine in unmetabolized form. The pharmacokinetic parameters obtained after 5-day administration were similar to those recorded after single administration. Concerning treatment response, a transient but significant reduction in the number of leukemic cells was observed in one patient with adult T-cell leukemia. In this study, perioral numbness, hypotension, and hematological toxicity were concluded to be dose-limiting, with the maximal acceptable dose being 500 mg/m2. The recommended dose for a phase II study of NKT-01 against solid tumors was judged to be 400 mg/m2 given daily by 3-h infusion for 5 days, every 3 weeks. In hematological malignancies, however, higher myelosuppressive schedules of administration should be investigated.

A multicentral cooperative study was conducted to evaluate the clinical efficacy and toxicity of l-Leucovorin (l-LV) and 5-fluorouracil (5-FU) in advanced colorectal cancer. The administration schedule was a two-hour intravenous infusion of l-LV (250 mg/m2) and an intravenous bolus injection of 5-FU (600 mg/m2), given one hour after the beginning of the l-LV infusion. Sixty-four patients were treated weekly for six weeks followed by two-weeks rest, and then evaluated for response. Complete response and partial response were obtained in 21 patients (32.8%). The median survival time was 12.8 months. The most prominent side effects were anorexia (57.8%), nausea and vomiting (56.3%), diarrhea (48.4%) and myelosuppression such as leucopenia (54.7%), thrombocytopenia (18.8%) and decreased hemoglobin (40.6%). These side effects, however, were within permissible levels. Severe toxicity was prevented by discontinuance of the treatment. From the present study, l-LV and 5-FU combination therapy seems to be a very promising and useful treatment for patients with advanced colorectal carcinoma.

The clinical phase I study of TNP-351, an antifolate drug having a novel structure, was performed through a multicenter cooperative program in 40 patients with solid tumors. The test drug was used on dosage schedules of single and daily doses for 5 or 3 days (by intravenous drip over 30 minutes, respectively). From the daily administration for 5 days, severe adverse reactions such as myelosuppression, became manifest at 5 mg/m2 (1n). This schedule was then switched to daily administration for 3 days. Administration of the test drug was initiated at a dose of 5 mg/m2. On a single-dose schedule, the dose was increased up to 100 mg/m2 (20 n), and on the 3-day daily administration schedule, up to 10.8 mg/m2 (2.2 n). Consequently, 26 of the study patients received single doses; three of them the 5-day daily administration, and 11 the 3-day daily administration. The dose-limiting factors were leukopenia and thrombopenia on both the single-dose and 3-day daily administration schedules. MTD was 100 mg/m2, and MAD, 75 mg/m2 for the single-dose schedule; and 10.8 mg/m2 and 9 mg/m2 for the 3-day daily administration schedule. WBC and platelet counts fell to nadirs at 1-2 weeks on either the single-dose or 3-day daily administration schedule, and it took the respective parameters about 1 week to recover. Subjective and objective adverse reactions to the test drug consisted of digestive tract disorders manifested as stomatitis, anorexia, nausea and vomiting; and laboratory abnormalities such as elevations of GOT and GPT in addition to the myelosuppression. Many of these adverse reactions subsided within 3 weeks after initiation of TNP-351 treatment. On the single-dose schedule, the test drug occurred chiefly in unchanged form in the blood, and in this form it disappeared from the blood biphasically with an alpha phase of 0.29-0.95 hours, and a beta phase of 7.8-14.4 hours. This disappearance pattern did not vary with an increase in dose. The 24-hour urinary excretion rate of the unchanged form amounted to 42-62% of the administered doses. On the 3-day daily administration schedule, the test drug was not accumulated in vivo. In the present study, two patients with malignant fibrous histiocytoma responded to the test drug with tumor regression. The results suggested that the recommended dosage regimen for the clinical early phase II study of the test drug should comprise a course of 9 mg/m2/day (by intravenous drip infusion over 30 minutes) every day for 3 days, which should be repeated every 3 weeks.

A preclinical toxicology study of liposome encapsulated vincristine, free vincristine and empty liposomes was carried out in mice and dogs by single and multiple (daily for 5 days) intravenous injection. Single and multiple dose intravenous injection studies in mice showed the encapsulated form of vincristine to be less toxic than free vincristine. Empty liposomes injected intravenously into dogs were without significant toxicity. In dogs, the toxicities seen with liposomal vincristine were qualitatively similar to those of free vincristine with only minor quantitative differences. The principal toxicities of free and liposomal vincristine in dogs were anorexia, weight loss, pyrexia, myelosuppression and gastrointestinal toxicity. After single high doses of either formulation gastrointestinal toxicity was the dose-limiting toxicity, while either hematologic or gastrointestinal toxicity was dose limiting after multiple dose administration of either drug. Histopathologic lesions of importance were bone marrow atrophy, necrosis and atrophy of the lymphoproliferative tissues, necrosis of gastrointestinal tract mucosa, liver and pancreas, and hemorrhage. Distribution studies in rats showed significantly higher vincristine levels in serum, spleen, liver, trachea, jejunum, cerebrum, lung, ischiatic nerve and heart, and significantly lower levels in colon, stomach, salivary gland, thymus esophagus and pancreas after injection of the liposome-associated agent. No toxicities were seen that should preclude safe clinical trial of liposomal vincristine in man.

Forty-four dogs with histologically confirmed malignant tumors were used in a prospective study to determine the toxicity of the chemotherapeutic agent mitoxantrone, when administered at dosages higher than what has been previously reported for use in dogs. After each dose was administered, dogs were evaluated for signs of toxicosis for 3 weeks or until the dog developed progressive disease, died, or was euthanatized. Forty dogs had been refractory to 1 or more treatment modalities (surgery, n = 26; chemotherapy other than mitoxantrone, n = 17; radiation, n = 2) prior to entering this study. Ten dogs were given mitoxantrone at a dosage of 5.5 mg/m2 of body surface, IV, every 3 weeks (39 total doses); 11 were given mitoxantrone at a dosage of 6.0 mg/m2, IV, every 3 weeks (26 total doses); and 23 were given mitoxantrone at a dosage of 6.5 mg/m2, IV, every 3 weeks (70 total doses). The most common signs of toxicosis were vomiting, anorexia, diarrhea, lethargy, and sepsis secondary to myelosuppression. Two dogs, both of which received the highest dosage, died of complications attributable to mitoxantrone administration. The prevalence of toxicoses was not associated with age, breed, sex, tumor type, number of doses, or dosage. Dogs did develop myelosuppression 7 days after they were given mitoxantrone.(ABSTRACT TRUNCATED AT 250 WORDS)

We conducted a multi-institutional (33 institutes), late phase II study with a 21-consecutive-day oral administration of etoposide for malignant lymphoma. Patient entry criteria were either those refractory to standard therapies or those for whom no appropriate therapy was available. A once-daily dose of 50 mg/body was administered for 21 consecutive days. Of the evaluable 83 among 88 entry patients, the overall response rate was 53.0% (44/83), including 10 CR; 52.5% (42/80, 9 CR) with non-Hodgkin's lymphoma and 100% (2/2, 1 CR) with Hodgkin's disease. Regarding abnormal laboratory findings, myelosuppression was observed; the incidence rates of leukopenia (23.3% with Grade 3), neutropenia (32.6%), hemoglobin decrease (17.4%) and thrombocytopenia (4.7%) were 70.9%, 65.1%, 54.7% and 19.8%, respectively. Major adverse reactions and their incidence were: anorexia 43.0%, alopecia 37.2%, nausea/vomiting 32.6%, fatigue 18.6%, stomatitis 15.1%, fever 7.0% and diarrhea 5.8%. Therefore, a 21-consecutive-day oral administration of 50 mg/body/day or 75 mg/body/day appears to be effective for the treatment of malignant lymphoma.

A late phase II study of CPT-11 for advanced breast cancer was conducted at 27 institutions. Seventy-nine patients were enrolled, 75 were eligible for the study, and 65 were evaluable for efficacy. One complete response and 14 partial responses were obtained, and the response rate was 23%. The response rate of patients with prior endocrine therapy and prior chemotherapy including adriamycin or other anthracycline drugs was 27% (11/41) and 26% (12/46), respectively. The response rate for patients with estrogen receptor-negative tumors and premenopausal patients was 32% (6/19) and 27% (4/15), respectively. Responses were observed not only for soft tissue lesions such as lymph nodes (5/17), but also for distant metastases in the lungs (8/28) and bone (1/18). The major adverse reactions were myelosuppression and gastrointestinal symptoms. The incidence of Grade 2 or higher leukopenia, anemia, nausea/vomiting, anorexia, diarrhea and alopecia was 68%, 31%, 67%, 59%, 37%, and 30%, respectively. These results suggested that CPT-11 was a promising drug for advanced breast cancer.
